Abstract:
There has been a recent increase in interest among evolutionary researchers in the hypothesis that humans evolved as cooperative breeders, using extended family support to help decrease offspring mortality and increase the number of children that can be successfully reared. In this study, data drawn from the 1970 longitudinal British cohort study were analysed to determine whether extended family support encourages fertility in contemporary Britain. The results showed that at age 30, reported frequency that participants saw their own parents (but not in-laws) and the closeness of the bond between the participant and their own parents were associated with an increased likelihood of having a child between ages 30 and 34. Financial help and reported grandparental childcare were not significantly positively associated with births from age 30 to 34. Men's income was positively associated with likelihood of birth, whereas women's income increased likelihood of birth only for working women with at least one child. While it was predicted that grandparental financial and childcare help would increase the likelihood of reproduction by lowering the cost to the parent of having a child, it appears that the mere physical presence of supportive parents rather than their financial or childcare help encouraged reproduction in the 1970 British birth cohort sample.

Abstract:
ObjectiveExamine the relationship between preconception stress and offspring birth weight.SettingPopulation-based cohort study linked with state-based administrative perinatal data.Participants6100 births from 3622 women from the 1973–1978 cohort of the Australian Longitudinal Study of Women’s Health who (1) recorded a singleton birth between January 1997 and December 2011; (2) returned at least one follow-up survey within 3 years of conception; and (3) had complete data on perceived stress prior to conception.Primary outcome measuresLinear generalised estimating equations were used to examine the relationship between preconception stress and a continuous measure of birth weight, exploring differences based on birth order and stress chronicity. The minimal sufficient adjustment set of covariates was determined by a directed acyclic graph.ResultsFor all births, there was no relationship between moderate/high acute or chronic stress and offspring birth weight in grams. Among first births only, there was a trend towards a relationship between moderate/high chronic stress and offspring birth weight. Offspring sex was associated with birth weight in all models, with female babies born lighter than male babies on average, after adjusting for covariates (p<0.0001).ConclusionsEffects of preconception stress on birth weight was largely driven by time to conception. With the timing of stress critical to its impact on obstetrical outcomes, preconception care should involve not only reproductive life planning but the space to provide interventions at critical periods so that optimal outcomes are achieved.

Abstract:
Background: The hypothesis that paracetamol may increase the risk of asthma and other allergic disease has gained consistent support from epidemiological studies, but evidence from longitudinal cohort studies, particularly those looking at the timing and dose of exposure are lacking. Epidemiological studies have also reported an inverse relation between gastro-intestinal infections including Helicobacter pylori, commensal bacteria and geohelminths and asthma and allergic disease, however, data from longitudinal birth cohort study are scarce. This thesis has therefore investigated the effects of paracetamol, H. pylori and other gastro-intestinal infections on the incidence and prevalence of allergic diseases and sensitization in a low-income birth cohort in which confounding by social advantage and other medical interventions is unlikely to play a role. Methods: In 2005/6 a population based cohort of 1065 pregnant women from Butajira, Ethiopia was established, to whom 1006 live singleton babies were born, and these children have been followed-up from birth to age five. At ages one, three and five, the International Study of Asthma and Allergies in Children (ISAAC) questionnaires were administered to the mothers to obtain data on wheeze, eczema and rhinitis. Allergen skin tests to Dermatophagoides pteronyssinus and cockroach were performed at ages three and five. Data on child's use of paracetamol, and various early life putative risk factors, including levels of Der p 1 and Bla g 1 allergen in the child's bedding and symptoms of respiratory tract infections were also measured. Stool samples were collected at ages three and five for analysis of H. pylori antigen using a rapid test (Medimar immunocard), as well as for geohelminths (at ages one, three and five) and selected commensal bacteria (at age three). Multivariate logistic regression was used to determine the independent effects of various markers of paracetamol use on the incidence of each outcome between age one and five, as well as on prevalence at age five. Similar analyses were also carried out to determine the independent effects of H. pylori, geohelminths and commensals on the incidence and prevalence of each outcome. Results: Effects of paracetamol: Of the 1006 children in the cohort at birth, 863 children were successfully followed up at age five (94% of surviving mother-child dyads). Wheeze and eczema incidence between the ages of one and five were reported in 5.9% (40/676) and 5.8% (39/700) of children respectively, and rhinitis and sensitization incidence between ages three and five were found in 3.9% (31/798) and 2.0% (15/766) of children respectively. Paracetamol use in the first three years of life was common, with 18% reported use at age one but not three, 23% at age three but not one and 21% at both time points. Use in the first year of life was significantly associated with a dose-dependent increased risk of incident wheeze between ages one and three (fully adjusted ORs, 95% CI, 1.77; 0.96, 3.26 for 1-3 tablets and 6.78; 1.89, 24.39 for ≥ 4 tablets in past month versus never), but not eczema. The risk of incident wheeze, eczema, rhinitis and sensitization between ages three and five was increased in those exposed, significantly so for incident eczema (p=0.02) and borderline significant for rhinitis (p=0.07), with fully adjusted odds ratios (ORs), including for symptoms of respiratory tract infections, for persistent exposure (ages one and three) versus never of 3.82 (95% CI 1.36, 10.73) and 3.10 (1.00, 9.57) respectively. Borderline significant trends were also seen between paracetamol dose in the first three years of life and incident eczema and rhinitis, with adjusted ORs for heavy reported use compared to low of 1.59 (0.44, 5.74; p trend=0.06) and 2.31 (0.72, 7.46; p trend=0.07) respectively, but not with incident wheeze (fully adjusted OR=3.64; 1.34, 9.90, p trend=0.11). Cross-sectional analysis at age five resulted in significant positive dose-response effects of lifetime use (use at ages one, three and five) in relation to the prevalence of all outcomes. Effects of gastro-intestinal infection H. pylori infection was found in 17% of the children at age three but not five, 21% at age five but not three years, and 25% at both ages. In the longitudinal analysis, H. pylori infection at age three was significantly associated with a decreased risk of incident eczema between ages three and five years (adjusted OR, 95% CI, 0.31; 0.10, 0.94, p=0.02), but the associations with incident wheeze, rhinitis and sensitization were not significant. In cross-sectional analysis at age three, H. pylori infection was associated with a borderline significant reduced risk of eczema (adjusted OR, 95% CI, 0.49; 0.24, 1.01, p=0.05) and D. pteronyssinus sensitization (adjusted OR, 95% CI, 0.42; 0.17, 1.08, p=0.07), and a significant inverse association between current exposure to H. pylori, and any sensitization at age five (adjusted OR, 95% CI, 0.26; 0.07, 0.92, p=0.02). However, no significant associations were seen for wheeze and rhinitis. The prevalence and intensity of geohelminth infection (hookworm, Ascaris lumbricoides and Trichuris trichiura) were found to be low in this cohort, with only 4% of children infected at age one, 9% at age three and only 0.2% at both ages. The risk of new onset wheeze between ages one and three was lower in those infected at age one (3.6%) than uninfected (7.8%), but infection was insufficiently prevalent to compute estimates of effect. Exposure to geohelminth infections in the first three years of life was not significantly associated with the incidence of reported outcomes or sensitization. However, A. lumbricoides infection was associated with a borderline increased risk of incident eczema between ages three and five (adjusted OR, 95% CI, 2.86; 1.04, 7.86, p=0.07). Children at age three were commonly colonized with enterococci 38% (207/544), lactobacilli 31% (169/544) and bifidobacteria 19% (103/544). However, none of these commensal bacteria were associated significantly with either incidence or prevalence of allergic outcomes. Conclusions: This longitudinal study from a developing country birth cohort provides further support for an association between early life use of paracetamol and increased risk of wheeze and allergic disease, which is unlikely to be explained by aspirin avoidance, reverse causation or confounding by indication. Furthermore, among young children in this cohort, the study found novel evidence to support the hypothesis of a protective effect of H. pylori infection on the risk of allergic disease, but no evidence to support an etiological role for the microflora enterococci, lactobacilli or bifidobacteria. The power of the study to explore the role of geohelminth infection on wheeze and allergic disease was limited by few infected children, and therefore understanding on this particular relation has not been much further advanced.

Abstract:
Abstract Attention deficit hyperactivity disorder (ADHD) and disruptive behavior disorder (DBD) are two very common and co-occurring psychiatric disorders among children and adolescents. They are among the leading reasons for clinical referrals to child and adolescent mental health facilities worldwide and have many unfavorable consequences with a high cost to society. In this thesis, the potential early risk factors associated with ADHD and/or DBD were examined, the current well-being of the adolescent with ADHD and/or DBD was evaluated and the later education and the psychiatric morbidity of the adolescent were researched. The study population in this thesis is based on a subsample of the Northern Finland Birth Cohort 1986 (NFBC 1986) containing 457 study subjects, of which 91 (19.9%) were diagnosed with ADHD, 44 (9.6%) with DBD, 72 (15.6%) with comorbid ADHD and DBD and 250 (54.7%) with neither of these disorders. Confirmatory factor analysis, Kaplan-Meier survival analysis, Kruskal-Wallis one-way analysis of variance and several regression analyses were carried out in the study. This thesis contains four original publications. The results in the first publication indicated that there are different risk factors in childhood associating with different behavioral problems in adolescence. The differences between behavioral problems were also visible in the results of the second publication, where those adolescents who were diagnosed with both ADHD and DBD had more severe conduct disorder symptoms and had increased risks for many psychiatric disorders. The results from the third publication suggested that those adolescents who were diagnosed with both ADHD and DBD fared worse in school at the end of ninth grade and were later less likely to achieve higher than basic education. Finally, the fourth publication showed that the adolescents diagnosed with DBD (both with and without ADHD) seemed to have an increased risk for admittance to the psychiatric inpatient hospital. This thesis underlines the differences between children and adolescents diagnosed with ADHD and/or DBD and emphasizes the role of comorbidity between these disorders as an indicator of poorer outcomes later in life
Tiivistelmä Tarkkaavaisuus- ja ylivilkkaushäiriö (attention deficit hyperactivity disorder, ADHD) sekä käytös- ja uhmakkuushäiriöt (disruptive behavior disorder, DBD) ovat hyvin yleisiä – ja usein yhtä aikaa ilmeneviä – lasten ja nuorten psyykkisiä häiriöitä. Nämä häiriöt ovat hyvin usein syynä lasten ja nuorten psykiatristen terveyspalveluiden käyttöön. Niillä on myös todettu olevan useita epätoivottuja seurauksia, joiden hoitaminen puolestaan nostaa yhteiskunnan kuluja. Tämä väitöskirjatyö tutkii mahdollisia varhaisia riskitekijöitä, jotka assosioituivat ADHD- ja/tai DBD-häiriöiden kanssa, arvioi näillä häiriöillä diagnosoitujen nuorten sen hetkistä hyvinvointia ja tutkii näiden nuorten kouluttautumista sekä muuta psykiatrista sairastavuutta. Tutkimusaineisto koostuu Pohjois-Suomen syntymäkohortti 1986 (Northern Finland Birth Cohort 1986, NFBC 1986) -aineiston osaotoksesta, johon kuuluu 457 henkilöä. Osaotoksesta 91:llä (19,9 %) oli diagnosoitu ADHD, 44:llä (9,6 %) DBD ja 72:lla (15,6 %) komorbidi ADHD ja DBD. 250 henkilöllä (54,7 %) osaotoksesta ei ollut diagnosoitu kumpaakaan diagnoosia. Aineiston analysoinnissa käytettiin konfirmatorista faktorianalyysiä, Kaplan-Meierin elossaolomenetelmää, Kruskal-Wallisin yksisuuntaista varianssianalyysiä ja useita regressioanalyysejä. Tämä väitöskirja koostuu neljästä osajulkaisusta. Ensimmäisen osajulkaisun tulokset osoittivat, että eri riskitekijät lapsuudessa assosioituivat eri käytösongelmiin nuoruudessa. Eri käytösongelmien eroavaisuudet olivat myös nähtävillä toisessa osajulkaisussa: niillä nuorilla, joilla oli diagnosoitu komorbidi ADHD ja DBD, todettiin olevan vakavampia käytöshäiriöiden oireita sekä kohonnut riski useisiin muihin psykiatrisiin sairauksiin. Kolmannen osajulkaisun tulokset viittasivat näiden nuorien, jotka oli diagnosoitu komorbidillä ADHD:lla ja DBD:llä, pärjäävän huonommin koulussa ja valmistuvan muita todennäköisemmin vain peruskoulusta. Lopuksi neljännessä osajulkaisussa todettiin, että DBD diagnoosin nuorena saaneilla (riippumatta ADHD diagnoosista) näytti olevan kohonnut riski psykiatriseen osastohoitoon joutumiselle. Tämä väitöskirjatyö alleviivaa tarkkaavaisuus- ja ylivilkkaushäiriöllä sekä käytös- ja uhmakkuushäiriöillä diagnosoitujen lasten ja nuorten eroavaisuuksia ja korostaa kyseisten häiriöiden komorbidin ilmenemisen roolia huonon lopputuloksen ennustetekijänä myöhemmin nuoren elämässä

Abstract:
The aim of this study is to examine the long-term cognitive effects and educational outcomes of being born small-for-gestational-age (SGA). It also assesses whether the family’s attitude towards education modifies the effect of SGA on cognitive performance. A total of 9598 children born in 1953 and living in the Stockholm metropolitan area in 1963 were included in this study. Data were obtained from the Stockholm Birth Cohort. Multiple ordinary least square regressions analyses suggest that SGA children have lower mean verbal, spatial and numerical test scores than appropriate-for-gestational-age (AGA) children. However, these differences are small. Other results from modification analyses indicate that the effect of SGA status on cognitive performance is modified by the family’s attitude towards education. Additional logistic regression analyses suggest that the unadjusted difference in log odds of attaining higher education is largely explained by the family’s attitude towards education. The results suggest that the detrimental influences of being born SGA on some cognitive and educational outcomes are limited and may be reduced.

Abstract:
Abstract Depression is a common mental disorder in the Finnish population. There are several biological, psychological and social factors in the background of depression. The aim of this study was to investigate depression in association with birth weight, age at menarche, obesity and metabolic syndrome using data from the Northern Finland 1966 Birth Cohort. A large, prospectively collected general population-based birth cohort of originally 12058 liveborn children was used as study population. The database provided information on birth characteristics and features of the primary family. The follow-up studies were performed at the age of 14 years by postal inquiry, and at the age of 31 years by postal inquiry and clinical examination. Information on age at menarche and weight and height was obtained from the postal questionnaire at 14 and 31 years and clinical examination at 31 years. Data on abdominal obesity and metabolic syndrome were gathered from the clinical examination. Data on depressive symptoms measured by the Hopkins Symptom Checklist-25 (HSCL-25), self-reported physician-diagnosed lifetime depression and the use of antidepressants were gathered from the postal questionnaire at 31 years. Females with high birth weight and high ponderal index (index of the birth measures, kg/m3) had a higher risk of depressive symptoms at 31 years measured by the HSCL-25 compared with females with normal birth weight and ponderal index. Males with ponderal index belonging to the lowest 5 percentile had an increased risk for physician-diagnosed depression at 31 years. Females with late menarche (≥ 16 years) had an elevated risk of depression measured by the HSCL-25, the use of antidepressants and self-reported physician-diagnosed depression compared with females with menarche at 12–15 years. Obesity measured by BMI at 14 years increased the risk of depressive symptoms measured by the HSCL-25 at 31 years among both males and females. Females who were obese both at baseline and at follow-up had an increased risk of depressive symptoms, and the proportion of those who used antidepressants was higher among females who had gained weight compared to females who had stayed normal-weighted. Males with abdominal obesity measured by waist-to-hip ratio had an increased risk of depressive symptoms and physician-diagnosed depression, and the proportion of those who used antidepressants was higher compared with subjects without abdominal obesity. Abdominal obesity did not associate with depression in females. Metabolic syndrome did not associate with depression. The results indicate an increased risk of depression at 31 years in females with high birth weight, late menarche, adolescent obesity and weight gain and in males with adolescent obesity and abdominal obesity
Tiivistelmä Depressio on yleinen mielenterveyden häiriö suomalaisväestössä. Depression taustalla on monia biologisia, psykologisia ja sosiaalisia tekijöitä. Tämän tutkimuksen tavoitteena oli tutkia depressiota selvittäen, onko syntymäpainolla, menarkeiällä, lihavuudella ja metabolisella oireyhtymällä yhteyttä depressioon Pohjois-Suomen vuoden 1966 syntymäkohorttiaineistossa. Tutkimusaineistoon kuului alun perin 12058 elävänä syntynyttä lasta. Tietokantaan oli jo aiemmin kerätty aineistoa syntymään ja primaariperheeseen liittyen. Kohortin jäsenten ollessa 14-vuotiaita tehtiin seurantatutkimus postikyselynä ja 31-vuotiaana tehtiin sekä postikysely että kliininen tutkimus. Tiedot menarkeiästä kerättiin 31-vuotispostikyselystä, paino- ja pituustiedot sekä 14- ja 31-vuotispostikyselyistä että kliinisen tutkimuksen tiedoista. Kliininen tutkimus sisälsi tiedot myös keskivartalolihavuuden ja metabolisen oireyhtymän määrittämiseksi. 31-vuotispostikyselyssä depressio-oireita kysyttiin HSCL-25 -oirekyselyllä; lisäksi kysyttiin, oliko lääkäri todennut aiemmin masennusta sekä oliko tutkittavilla käytössä masennuslääkkeitä. Naisilla, joiden syntymäpaino ja ponderaali-indeksi (syntymäpainon ja pituuden suhdetta kuvaava indeksi, kg/m3) oli korkea, depressio-oireiden riski 31-vuotiaana mitattuna HSCL-25:lla oli suurentunut verrattuna naisiin, joilla oli normaali syntymäpaino ja ponderaali-indeksi. Miehillä, joilla oli hyvin alhainen ponderaali-indeksi kuuluen alimpaan 5 % ryhmään, riski lääkärin toteamaan masennukseen oli suurentunut. Naisilla, joiden menarkeikä oli 16-vuotta tai myöhemmin, riski depressio-oireiden esiintyvyyteen, depressiolääkkeiden käyttöön ja lääkärin toteaman depression esiintyvyyteen oli suurentunut verrattuna naisiin, joiden menarkeikä oli 12–15-vuotta. Lihavuus 14-vuotiaana lisäsi masennusoireiden riskiä mitattuna HSCL-25:lla sekä 31-vuotiailla miehillä että naisilla. Naisilla, jotka olivat lihavia sekä 14- että 31-vuotiaana, masennusoireiden riski oli suurentunut. Naisilla, joiden paino oli noussut, masennuslääkkeitten käyttö oli yleisempää verrattuna naisiin, joilla paino oli pysynyt normaalina. Keskivartalolihavuus oli miehillä yhteydessä suurentuneeseen depressio-oireiden ja lääkärin toteaman masennuksen riskiin, ja he käyttivät yleisemmin masennuslääkkeitä verrattuna miehiin ilman keskivartalolihavuutta. Naisilla keskivartalolihavuus ei ollut yhteydessä masennukseen. Metabolinen oireyhtymä ei ollut yhteydessä masennukseen. Tulokset osoittavat korkean syntymäpainon, myöhäisen menarkeiän ja nuoruusiän lihavuuden sekä painon nousun lisäävän masennusriskiä 31-vuotiailla naisilla, 31-vuotiailla miehillä nuoruusiän lihavuus sekä keskivartalolihavuus olivat yhteydessä suurentuneeseen masennusriskiin

Abstract:
Streptococcus pneumoniae (the pneumococcus) is the most common cause of childhood pneumonia. Nasopharyngeal (NP) colonization by the pneumococcus is a necessary first step in the pathogenesis of pneumonia and yet the dynamic nature of pneumococcal colonization remains incompletely understood. In children, asymptomatic colonization of the nasopharynx by the pneumococcus is common and also serves as a reservoir for person-to-person transmission. We aimed to investigate in detail, the dynamics of pneumococcal nasopharyngeal carriage over the first year of life, in a cohort of South African children, particularly after implementation of the 13-valent pneumococcal conjugate vaccine (PCV-13). The study will further elucidate the interaction of S. pneumoniae with other respiratory pathogens and how such interactions may contribute development of severe disease.

Abstract:
Much is known about childbirth fear in Sweden including its relationship to caesarean birth. Less is understood about this in Australia. Sweden has half the rate of caesarean birth compared to Australia. Little has been reported about women’s beliefs and attitudes to birth in either country. The contribution of psychosocial factors such as fear, attitudes and beliefs about childbirth to the global escalation of caesarean birth in high-income countries is an important topic of debate. The overall aim of this thesis is to investigate the prevalence and impact of fear on birthing outcomes in two cohorts of pregnant women from Australia and Sweden and to explore the birth attitudes and beliefs of these women.   A prospective longitudinal cohort study from two towns in Australia and Sweden (N=509) was undertaken in the years 2007-2009. Pregnant women completed self-report questionnaires at mid-pregnancy, late pregnancy and two months after birth. Fear of birth was measured in mid-pregnancy with a tool developed in this study: the Fear of Birth Scale (FOBS). The FOBS showed promise as a clinically practical way to identify women with significant fear. A similar prevalence of fear of birth (30 percent) was found in the Australian and Swedish cohorts (Paper I).  The Swedish women had attitudes indicating a greater concern for the personal impacts of birth and a belief system that situated birth as a natural event when compared to the Australian women (Paper II). Finally, when women’s attitudes and levels of fear were combined, three profiles were identified: Self determiners, Take it as it comes and Fearful (Paper III). Belonging to the Fearful profile had the most negative outcomes for women including higher rates of elective caesarean, more negative feelings in pregnancy and post birth and poorer perceptions of the quality of their antenatal and intra-partum care (Paper IV).

The Northern Finland 1966 Birth Cohort (NFBC 1966) consists of 12,068 pregnant women with expected dates of delivery in 1966, and their 12,058 live-born children. The data used here was collected prospectively for 10,934 individuals who were alive and resident in Finland at the age of 16. This study utilized an extensive data set collected in antenatal clinics at mid-pregnancy, by postal questionnaire at the age of 14 years and through national registers. A total of 121 suicide attempts (57 males) and 69 suicides (56 males) had occurred by the end of 2005. A single-parent family was a risk factor for attempted suicides and grand multiparity for suicides in male offspring. Adolescent regular smoking was associated with an increased risk of suicide attempts in both genders and for suicide among males. Good school performance at age 16 years was associated with an increased risk of suicide in psychosis cases, whereas in persons who did not develop psychosis it was associated with a lower suicide risk. The suicide rate in new-onset schizophrenia followed until the age of 39 was 7%. Over two thirds of the suicides took place during the first 3 years of the illness. This was the first study of suicide rates in a prospectively followed population-based birth cohort of individuals with schizophrenia. This study replicated association between some early family-related risk factors for attempted and accomplished suicide, and also presented data for previously unstudied early factors, namely maternal antenatal depression, smoking and unwanted pregnancy This study has clarified the association between adolescent smoking and later suicide risk. It also revealed the association between good school performance and elevated risk of suicide in psychotic people, in contrast to its protective effect in the non-psychotic population. However, even though there were significant antenatal and developmental risk factors, a later psychiatric disorder seems to be the major risk factor for both attempted and accomplished suicide. Nevertheless, suicide usually seems to be a long multifactorial process that begins in early life and has complex trajectories in adolescence or early midlife
Tiivistelmä Tämän tutkimuksen tarkoitus oli tutkia itsemurhien esiintyvyyttä, riskitekijöitä, siihen johtavia kehityspolkuja yleisväestöön perustuvassa prospektiivisessa pitkittäistutkimuksessa. Pohjois-Suomen vuoden 1966 syntymäkohorttiin kuului alun perin 12,068 raskaana olevaa naista joiden laskettu aika oli vuonna 1966, ja heidän 12,058 elävänä syntynyttä lastaan, kohortin jäsenet. Tässä tutkimuksessa käytetty aineisto on kerätty 11,017 kohortin jäsenestä, jotka olivat elossa ja asuivat Suomessa 16-vuotiaana. Käytetty aineisto on kerätty äitiysneuvoloissa, 14-vuotiaana tehdyssä postikyselyssä ja kansallisista rekistereistä. Kaikkiaan 121 itsemurhayritystä (joista 57 miehillä) ja 69 itsemurhaa (56 miehillä) tapahtui vuoden 2005 loppuun mennessä. Yhden vanhemman perhe syntymän aikaan oli riski myöhemmälle itsemurhayritykselle ja syntyminen monilapsiseen perheeseen (yli viisi lasta) oli riski itsemurhalle. Tupakointi 14-vuotiaana ennusti itsemurhayrityksiä kummallakin sukupuolella sekä itsemurhia miehillä. Hyvä koulumenestys 16-vuotiaana liittyi kohonneeseen itsemurhavaaraan niillä jotka myöhemmin sairastuivat psykoosiin, kun muilla se liittyi alentuneeseen vaaraan. Skitsofreniaan sairastuneista 7 % teki itsemurhan ja yli kaksi kolmannesta skitsofreniaan sairastuneiden itsemurhista tapahtui kolmen vuoden kuluessa sairastumisesta. Tämä tutkimus vahvisti aikaisempia havaintoja varhaisista riskitekijöistä itsemurhayrityksiin ja itsemurhiin. Tässä tutkimuksessa tutkittiin myös kokonaan uusia varhaisia riskitekijöitä, joita ei ole ennen tutkittu suhteessa itsemurhaan tai itsemurhayrityksiin, kuten äidin raskaudenaikainen masennus ja tupakointi sekä ei-toivottu raskaus. Tämän tutkimuksen avulla saatiin myös uutta tietoa teini-iässä aloitetun tupakoinnin suhteesta itsemurhiin ja -yrityksiin. Tutkimus paljasti hyvän koulumenestyksen lisäävän riskiä itsemurhaan henkilöillä jotka sairastuvat myöhemmin psykoosiin. Tämä oli ensimmäinen tutkimus, jossa skitsofreniaa sairastavien henkilöiden itsemurhakuolleisuutta selvitettiin yleisväestöön pohjautuvassa syntymäkohortissa. Vaikka tutkimuksessa tuli ilmi sekä syntymän, että nuoruuden aikaisia varhaisia riskitekijöitä, myöhempi psykiatrinen sairaus on merkittävin itsemurhan ja -yritysten riskitekijä. Siitä huolimatta itsemurha on aina monitekijäinen prosessi, joka voi alkaa jo ennen syntymää ja johon myöhemmät elämänvaiheet vaikuttavat

Abstract:
Background: Childhood excess weight and family food insecurity are food-system related public health problems that exist in Canada. Since both relate to issues of food accessibility and availability, which have elements of “place”, they may share common risk factors in the local environment that are amenable to intervention. In this area of research, the literature derives mostly from a US context, and there is a dearth of high quality evidence, specifically from longitudinal studies. Objectives: The main objectives of this thesis were to examine the adjusted associations between the place factors: material deprivation, social deprivation, social cohesion, disorder, and living location, with change in child BMI Z-score and with change in family food insecurity status in a Canadian cohort of children. Methods: The Québec Longitudinal Study of Child Development was used to meet the main objectives of this thesis. Response data from six collection cycles (4 – 10 years of age) were used in three main analyses. The first analysis examined change in child BMI Z-score as a function of the place factors using mixed models regression. The second analysis examined change in child BMI Z-score as a function of place factors using group-based trajectory modeling. The third and final analysis examined change in family food insecurity status as a function of the place factors using generalized estimating equations. Results: Social deprivation, social cohesion and disorder were strongly and positively associated with family food insecurity, increasing the odds by 45-76%. These place factors, on the other hand, were not consistently associated with child weight status. Material deprivation was not important for either outcome, except for a slight positive association in the mixed models analysis of child weight status. Living location was not important in explaining family food insecurity. On the other hand, it was associated with child weight status in both analyses, but the nature of the relationship is still unclear. Conclusions: Results do not suggest that addressing similar place factors may alleviate both child excess weight and family food insecurity. More high quality longitudinal and experimental studies are needed to clarify relationships between the local environment and child weight status and family food insecurity.

Abstract:
[Truncated abstract] Asthma is a chronic and complex disorder and despite our increase in the understanding of the genetics, pathology and mechanisms underlying asthma a gold standard definition of asthma does not exist. A criterion for recognising and diagnosing asthma in epidemiological studies is crucial in order to determine risk factors for disease. Prospective longitudinal birth cohort studies have increased our understanding of the natural history and risk factors for asthma, yet we are still not able to accurately predict which children will go on to have asthma as adults. It is during the transition from childhood to adolescence where factors underlying asthma change and the prevalence of asthma shifts between the sexes. There are inconsistencies regarding risk factors for the development and persistence of disease during this transitional period. Risk factors predicting the development and persistence of asthma and intermediate phenotypes (BHR, airway inflammation and atopy) may be influenced by gender and risk factors predicting disease may differ between childhood and adolescence. Aims 1. To identify risk factors for Asthma, BHR and Atopy at 14yrs of age. 2. To determine risk factors for persistence of asthma between 6 and 14 years. 3. To examine the influence of gender on risk factors during adolescence. Method The West Australian Pregnancy Cohort is a longitudinal birth cohort. The cohort initially consisted of 2868 live births with follow-ups at 1, 2, 3, 6, 8, 10 and 14 years of V age. ... Strong associations were seen with BHR and new diagnosis of wheeze and asthma in VI teenagers. Interestingly having either a cat or dog inside was protective for persistence of disease; in particular stronger associations were seen in teenage girls not in boys. During this transitional period the risk factors for asthma and intermediate phenotypes differ between the sexes. Different mechanisms are likely to be involved in determining asthma in boys and girls during adolescence and shed new light on the recognised switch in the gender balance in asthma prevalence from the male predominance in childhood to the female predominance in adult life. Our understanding of the natural course of disease from the prenatal period to adulthood and the identification of the various asthma phenotypes has the potential to change prognosis and planning of therapeutic strategies. Identifying those at high risk for persistence of disease in the early stages of life will allow therapeutic interventions to be more appropriately targeted.

Abstract:
Mental health reflects an array of causal influences that span biological, psychological, and social circumstances, with resultant underlying causal pathways to poor mental health outcomes in childhood that are complex. Key features of this complexity are reciprocal interactions between person and environment that take place over time. The core of this thesis seeks to attend to the complexity of development to move the field of developmental health forward toward greater explanation, and more successful prediction and prevention. The focal point of the thesis is the psychosocial determinants of childhood mental health, the resource domain of the developing child, and the interplay between characteristics of the individual child, the family, and the community. The eventual goal is to better understand why and how socioeconomic circumstances impact on developmental health. One component of this thesis focuses on the expansion of extant developmental theory. The other component focuses on the development of an analytic strategy that more appropriately reflects the intricacies of this theoretical expansion. In the process, data are analysed, principally as a heuristic strategy, to illustrate the analytical approach needed to support the theoretical framework. The specification of a bioecological conceptual framework suitable to guide research and policy in developmental health is the first principal objective of the thesis. A critical examination of the resource framework proposed by Brooks-Gunn, Brown, Duncan, and Anderson Moore (1995) reveals it to be centred on family and community resources, but otherwise silent with respect to the physical and psychological resources of the child. The quintessential point of this thesis is that theory in developmental health must be able to account for the contribution individuals make to their own development. A modified resource framework is proposed that acknowledges financial, physical, human, and social capital, within the domains of the individual child, the family, and the community. The second principal objective of the thesis, the development of analytical methods that focus on the individual child and the complexity of data generated by this theoretical approach, is then introduced. Theory and method are thus integrated when comprehensive measures of characteristics in multiple domains across developmental periods are modeled using longitudinal data from the Western Australian Pregnancy Cohort (Raine) Study (Newnham, Evans, Michael, Stanley, & Landau, 1993). The mothers of 2,860 children were enrolled at 18 weeks in pregnancy and the children have been followed at birth, one, two, three, five, and eight years of age. Eighty-nine per cent (2,537 /2,860) of families were available for follow-up at eight and 74 per cent (2,126/2,860) of families responded. Extensive demographic, psychological, and developmental data were available for the children and their families and a limited amount of data were available for the communities in which they reside. A measure of mental health morbidity, the Child Behaviour Checklist (Achenbach, 1991), was available for the children at two, five, and eight years of age. In the first instance, dichotomous summary variables are derived for the demographic, psychological, and developmental variables of interest. Variables are then selected for inclusion in one of several explanatory models. To create a mathematical representation of resource characteristics, the information for each child is concatenated as a series of binary strings. Frequency tabulation is then used to aggregate the data and odds ratios are calculated to determine the degree of risk associated with each string of code, or pattern of factors relative to a nominated mental health outcome. The results provided a scaffold from which this theoretical and analytical approach is compared and contrasted with the reviewed literature. Two principal themes of investigation are pursued. The first theme to be examined is the interplay between characteristics of the child, family, and community and the contribution children make to their own development. The specific approach models the interaction between selected characteristics of the child, family and community in each of four developmentally significant time periods. The theoretical position adopted in the present study suggests that the effect of any personal or contextual factor on later development, if a relationship does truly exist, is most likely to be differential. That is, it is a combination of influences that determines developmental outcomes for children, not any single factor acting independently. The modelling process demonstrates that, for the children involved, personal and contextual factors impact mental health differentially depending on various other individual, family and/or community characteristics. The modelling process identifies patterns of factors that impact relatively small, but significant, numbers of children because the models focus on the effect for individual children rather than the effect for the group. For example, one model suggests that the effect of intra-uterine growth restriction for the group as a whole may be minimal, but the impact for some children could be critical depending on the combination of family and community influences, such as the mothers level of education, the family’s experience of significant life stress, and residence in a relatively disadvantaged community. The second theme to be examined is the possibility that the accumulation of resource deficits or risk characteristics, over time, amplifies the likelihood of mental health problems in childhood. The approach models selected characteristics of the child in each of the four periods of development collectively, and it also models selected characteristics spanning each of the four time periods discretely. The results suggest that latency, pathway, and recency effects may operate simultaneously, and that timing and accumulated burden may both be important determinants of risk. For example, with regard to children whose family experienced life stress, these three effects operated in a systematic way to increase the degree of risk of a mental health problem. In summary, the aggregation of data at the individual level is a productive approach in seeking to explain population level social phenomena. While seemingly paradoxical, the identification of the joint, interactive effects between individual, family, and community characteristics, better allows for the quantification of family and community characteristics operating through multiple causal pathways.

Abstract:
Objectives. To assess the comparative effectiveness and potential harms of cervical ripening in the outpatient setting (vs. inpatient, vs. other outpatient intervention) and of fetal surveillance when a prostaglandin is used for cervical ripening. Data sources. Electronic databases (Ovid® MEDLINE®, Embase®, CINAHL®, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews) to July 2020; reference lists; and a Federal Register notice. Review methods. Using predefined criteria and dual review, we selected randomized controlled trials (RCTs) and cohort studies of cervical ripening comparing prostaglandins and mechanical methods in outpatient versus inpatient settings; one outpatient method versus another (including placebo or expectant management); and different methods/protocols for fetal surveillance in cervical ripening using prostaglandins. When data from similar study designs, populations, and outcomes were available, random effects using profile likelihood meta-analyses were conducted. Inconsistency (using I2) and small sample size bias (publication bias, if ≥10 studies) were assessed. Strength of evidence (SOE) was assessed. All review methods followed Agency for Healthcare Research and Quality Evidence-based Practice Center methods guidance. Results. We included 30 RCTs and 10 cohort studies (73% fair quality) involving 9,618 women. The evidence is most applicable to women aged 25 to 30 years with singleton, vertex presentation and low-risk pregnancies. No studies on fetal surveillance were found. The frequency of cesarean delivery (2 RCTs, 4 cohort studies) or suspected neonatal sepsis (2 RCTs) was not significantly different using outpatient versus inpatient dinoprostone for cervical ripening (SOE: low). In comparisons of outpatient versus inpatient single-balloon catheters (3 RCTs, 2 cohort studies), differences between groups on cesarean delivery, birth trauma (e.g., cephalohematoma), and uterine infection were small and not statistically significant (SOE: low), and while shoulder dystocia occurred less frequently in the outpatient group (1 RCT; 3% vs. 11%), the difference was not statistically significant (SOE: low). In comparing outpatient catheters and inpatient dinoprostone (1 double-balloon and 1 single-balloon RCT), the difference between groups for both cesarean delivery and postpartum hemorrhage was small and not statistically significant (SOE: low). Evidence on other outcomes in these comparisons and for misoprostol, double-balloon catheters, and hygroscopic dilators was insufficient to draw conclusions. In head to head comparisons in the outpatient setting, the frequency of cesarean delivery was not significantly different between 2.5 mg and 5 mg dinoprostone gel, or latex and silicone single-balloon catheters (1 RCT each, SOE: low). Differences between prostaglandins and placebo for cervical ripening were small and not significantly different for cesarean delivery (12 RCTs), shoulder dystocia (3 RCTs), or uterine infection (7 RCTs) (SOE: low). These findings did not change according to the specific prostaglandin, route of administration, study quality, or gestational age. Small, nonsignificant differences in the frequency of cesarean delivery (6 RCTs) and uterine infection (3 RCTs) were also found between dinoprostone and either membrane sweeping or expectant management (SOE: low). These findings did not change according to the specific prostaglandin or study quality. Evidence on other comparisons (e.g., single-balloon catheter vs. dinoprostone) or other outcomes was insufficient. For all comparisons, there was insufficient evidence on other important outcomes such as perinatal mortality and time from admission to vaginal birth. Limitations of the evidence include the quantity, quality, and sample sizes of trials for specific interventions, particularly rare harm outcomes. Conclusions. In women with low-risk pregnancies, the risk of cesarean delivery and fetal, neonatal, or maternal harms using either dinoprostone or single-balloon catheters was not significantly different for cervical ripening in the outpatient versus inpatient setting, and similar when compared with placebo, expectant management, or membrane sweeping in the outpatient setting. This evidence is low strength, and future studies are needed to confirm these findings.

Abstract:
Researchers in the USA and Australia have found that sleep disturbances from early childhood are associated with reductions in well-being at age 10-11 years old. Ariel Williamson and colleagues came to this conclusion after analysing data from >5,000 children enrolled in the Longitudinal Study of Australian Children – Birth Cohort.
