Abstract:

The article aims to analyze the development of the basic characteristics of the demographic dynamics in the CR in urban areas divided according to size in 1993−2004 and to express the changes in the development of the natural increase. Urban areas in the CR were divided into 3 groups according to their size (size-related groups): urban areas of up to 2 000 inhabitants − a country type, urban areas with 2 000 to 10 000 inhabitants − a transition type, urban areas with more than 10 000 inhabitants − towns. In 2004, there were 26% of inhabitants living in the country group, 20% in the transition group and 54% in towns. There was a decline in marriage rate in all the groups; in the country, with its higher level, the decline was more moderate. The divorce rate shows a moderate increase except 1999, when it dramatically fell thanks to the legislation. The divorce rate was the highest in towns and the lowest in the country. The birth rate continued its sharp decline in urban areas of all sizes during the first four years of the researched period, then it levelled off, and it has even been slightly rising in the last years. It was considerably lower in bigger towns than in the other two groups, which had practically an identical development. There was a kind of balance at the end of the period. The death rate was generally going down; it was the highest in the country areas, however, it was approximating the values in the other two groups. The dramatic fall of the natural increase levelled off and it also showed a moderate rise. Trends are expressed with polynomial functions. The article presents the characteristics development in graphs and the reasons for changes are being commented upon.

Abstract:

Welcome to the Advancing Practice series Exploring Caesarean Birth and Birth After Caesarean. In Australia, the caesarean birth rate has risen to 37.2%, rising from 7% in 1980, translating to an increase of over 500% in 52 years. In this series we will look at the growing trend for caesarean birth, the reasons women have caesarean births, the risks associated, and the maternal mortality rate associated with caesarean births. A look at some consumer feedback about their experience of caesarean birth will highlight the gaps in knowledge for some women. In addition, the status of childbirth education for women who have caesarean births will also be explored.

Abstract:

ObjectivesTo investigate time trends of preterm birth and estimate the contributions of risk factors to the changes in preterm birth rates over a decade (2009–2018) of transitional period in Shenzhen, China.DesignRetrospective cohort study between 2009 and 2018.SettingAll births in Baoan during January 2009 and December 2018 registered in the Shenzhen Birth Registry Database.Participants478 044 live births were included with sociodemographic and medical records for both women and infants.Outcome measuresThe incidence rate of preterm birth stratified by different maternal and infant characteristics. Multiple logistic regression was used to identify significant risk factors associated with preterm birth. The population attributable risk fraction of each factor was calculated to estimate its contribution to variations of preterm birth rate over the 10 years.ResultsA total of 27 829 preterm births from 478 044 (5.8%) live births were recorded and the preterm birth rate increased from 5.5% in 2009 to 6.2% in 2018. Medically induced preterm birth rate increased from 2.0% in 2009 to 3.4% in 2018 while spontaneous preterm labour rate decreased from 3.3% to 2.7% over the decade years. Risk factors including multiple pregnancy (0.28% increase) drove the rise of preterm birth rate, whereas changes in maternal educational attainment (0.22% reduction) and prenatal care utilisation (0.45% reduction) had contributed to the decline in preterm birth rate.ConclusionsAn uptrend of preterm birth rate was observed in an area under rapid sociodemographic transitions during 2009–2018 and the changes were associated with these sociodemographic transitions. Continued investments in girls’ education and prenatal care have the potential of reducing preterm birth rate.

AbstractA study was initiated to investigate the impact of information dissemination in Illinois upon the projected rise in the cesarean birth rate over the period from 1986 through 1988. The total cesarean birth rate in Illinois had not changed significantly during this period, whereas the rate of vaginal births after cesarean sections (VBAC) increased by 58.4% (p <.001). Information dissemination may have contributed to stemming an increase in the cesarean birth rate in Illinois while promoting VBAC deliveries.

Abstract:

INTRODUCTION: To take an epidemiologic look at the most up-to-date geographical variation in the average teenage birth rates by county in the United States. METHODS: Data from the National Center for Health Statistics were used in this retrospective cohort to count the total number of live births to females aged 15–19 years by county between 2003 and 2020. Software for disease surveillance and spatial cluster analysis was used to identify clusters of high or low birth rates in counties or areas of greater than 100,000 teenage females. The data were then further analyzed by unemployment rate, no high school diploma rate, Hispanic rate, African American rate, and poverty rate per county as influence on the prediction of teenage birth rate. RESULTS: Spatial analysis identified 94 significant spatial clusters of teenage births. When adjusted for time and space, there were three significant clusters within Texas, all within 2013–2020, showing a steep increase in teenage birth rates. The top cluster with a 60% higher chance of teenage birth than the remainder of the country. Individual covariates examined showed the best predicter of teenage birth is unemployment followed by low education. CONCLUSION: Nationally, teenage births have declined over the last 30 years; however, clusters of elevated teenage birth rates remain predominantly in the southeastern United States and Texas. When adjusting for covariates of social determinants of health, some of these clusters remained, indicating other factors with influence on teenage birth rate.

Abstract:

This research was conducted to investigate the relevance of lamb sex, birth type and birth rate on birth distribution within the 24 h daily cycle in Anatolian Merino sheep. The aim is to find solutions to problems that could arise in this subject. Birth records from 981 ewes and their 1,175 lambs from 2010–2011 were used for the study. The twin birth rate was 19.78% and the females were 54.54% and males 45.46%. The percentage of lambs born between 22: 01 and 04: 00, 04: 01 and 10:00, 10: 01 and 16: 00, and 16: 01 and 22: 00 was 25.99%, 29.36%, 25.57% and 20.08% respectively. For sheep giving birth for the first time, the highest birth rate (27.18%) was between 04: 01 and 10: 00, while for sheep giving birth for the second, third or fourth time the percentages were 28.88, 31.78 and 29.26%, respectively, and the births occurred at the same time. In the study, 53.93% of births took place during daylight hours while 46.07% of births took place at night. The percentage of births between 22: 00 and 04: 00 was 25.99%.

Abstract:

Abstract Introduction Preterm birth-related complications are the leading cause of under-5 mortality globally. Bhutan does not have a reliable preterm birth rate or data regarding outcome of preterm babies. Aim To determine the preterm birth rate at the Jigme Dorji Wangchuck National Referral Hospital (JDWNRH) in Thimphu, Bhutan, and assess their outcomes. Methods All live preterm births at JDWNRH from 1 January 2017 to 31 December 2017 were followed from birth till hospital discharge. Maternal demographic data, pregnancy details and delivery details were collected. Morbidity and mortality information as well as discharge outcome were collected on babies admitted to neonatal intensive care unit (NICU). Results Preterm birth rate among live births was 6.4%. Most mothers were younger than 30 years, housewives and had secondary education. Pregnancy registration rate and adequacy of antenatal visits were high. Most preterm births were singleton and the predominant mode of delivery was cesarean section. More than half of the births were initiated spontaneously, and the male:female ratio was 1.2:1. Most babies were late preterm and low birth weight. Half of them required NICU admission. Overall mortality rate was 11% and 21.6% for admitted preterm neonates. Preterm small-for-gestational-age neonates, and those born after provider-initiated preterm birth had significantly increased risk of mortality. Most preterm neonates were discharged without complications. The rate of extrauterine growth restriction was high. Conclusion This is the first study on the prevalence of preterm births and their outcomes in the largest tertiary-care hospital in Bhutan.

Abstract:

The birth rate is one of the factors increasing the rate of population growth. Birth or fertility can affect the population, getting more lower of birth rate in an area, the higher the life expectancy in that area. The number of births in Randau Jekak Village is increasing every year. The Naïve Bayes algorithm can be used to predict the future births rate because this algorithm is a simple algorithm and uses a lot of data as information in collecting data groups, and with data mining techniques it can see the predictive pattern of each variable and test. The testing data and the training data are expected to help the Village Institution or Office in Randau Jekak to suppressing the rate of population growth which increases every year. The results of this study can be concluded that the Naïve Bayes Algorithm is suitable for predicting the birth rate of babies in Randau Jekak Village with the classification technique, the birth rate in Randau Jekak Village in 2021 is High. The results of this data will be very useful for the Randau Jekak Village office in suppressing the rate of population growth in the coming year.

Abstract:

The quantity and quality of the population are crucial to the prosperity of a country and a nation. The birth rate is a key indicator that affects future fertility levels. Data from the National Bureau of Statistics showed that the number of births in 2022 reached the lowest level in 60 years, ranking China among countries with a low fertility rate. So far, many scholars have studied the micro-influencing factors of the population birth rate in China. However, the mechanism of population birth rates is complex. There is a certain research gap in the current research on population birth rates by using multiple variable selection methods. Based on this, this paper attempts to use the variable selection method to make a comprehensive study of the macro factors affecting the birth rate in China and draws a conclusion. In the early days of the founding of New China, the natural environment and population factors were the main factors affecting fertility levels. Since the reform and opening up, social environment factors have become the main factors affecting the fertility level of the population. To predict the future birth rate of China, the influence of fertility policy will be further reduced, and economic and social factors will become the main factors affecting population fertility.

Abstract:

The research featured the decline of legitimate birth rate in the context of the transformation that family institution is currently undergoing. According to the Demography National project of the Russian Federation, the key objective of the national demographic policy is to increase the number of children up to 1.7 per woman. The authors believe that it is impossible to achieve the target indicator without revealing the institutional capacity of the so-called traditional family, which has a lower the level of birth control by abortion and contraception. In order to determine the institutional capacity of the national project, the authors estimated the legitimate birth rate and the level of birth control by the population. The methods involved the Coale-Trussell’s model, which is based on the assumption that controlled birth rate deviates from natural birth rate. The study was based on the data about the number of births in 2017. The data were obtained from twelve Siberian regions and included such information as maternal age and legitimacy. The Coale-Trussell’s model revealed a good institutional capacity that can enhance the demographic function of the family and increase the birth rate.

Abstract:

Objectives. To evaluate which type of embryo transfer (ET) has a superior pregnancy rate. Material and method. Prospective observational non-randomized study including 79 women that underwent 145 ET. Outcomes. The results show that the highest biochemical pregnancy rate (BPR) was in the fresh day 3 ET group (47.62%), but in this group there were also the highest abortion rate (80%) and the highest premature birth rate (100%), giving that, after 21 fresh day 3 ET did not result any term live birth. The frozen day 3 embryo has the lowest BPR (30%), but also the lowest abortion rate (33.33%) and the lowest premature birth rate (0%), in the present study after 13 frozen day 3 ET resulting 2 full-term births (15.38%). The results for the fresh day 5 blastocyst show a good BPR (43.48%), a low abortion rate (33.33%) and the lowest premature birth rate (0%), giving that in the study performed after 23 day 5 ET resulted 4 newborns at term (15.38%). The frozen day 5 blastocyst has a very good BPR (46.07%), the highest birth rate (21.62%), a high abortion rate (37.14%) and a low premature birth rate (7.41%), taking into account that in the present study after 89 day 5 frozen ET resulted 24 newborns, of which 22 full-term births (24.71%). Conclusions. The use of frozen day 5 blastocysts had the best results in terms of the ultimate goal - the birth of a live fetus at term.

Abstract:

ImportanceThe US has high rates of adverse birth outcomes, with substantial racial disparities augmented by stress and neighborhood disadvantage. Black people are more likely to live in neighborhoods with high rates of incarceration, which is a source of both stress and neighborhood disadvantage and, thus, may contribute to adverse birth outcomes.ObjectiveTo determine whether neighborhoods with high incarceration rates also have higher rates of adverse birth outcomes compared with neighborhoods with lower rates.Design, Setting, and ParticipantsThis cross-sectional study used publicly available data from the New York City Department of Health (2010-2014). Censored Poisson regression, with the US Census tract as the unit of analysis, was used to examine the association of neighborhood incarceration rate and birth outcomes. Multivariable models included percentage of births aggregated to the Census tract by maternal factors (age, parity, singleton vs multiple birth, insurance, and race) and neighborhood factors (poverty, education, and violent crime). Analyses were performed between May 2021 and October 2022.ExposureNeighborhood incarceration rate, categorized into quintiles.Main Outcomes and MeasuresThe primary outcome was the incidence rate ratio (IRR) of preterm birth and low birth weight. Secondary outcomes were IRRs of very preterm birth, extremely preterm birth, and very low birth weight. Hypotheses were formulated before data collection.ResultsAmong 2061 Census tracts with 562 339 births, incarceration rates varied from 0 to 4545 people incarcerated per 100 000, and high-incarceration neighborhoods had more residents of Black race (54.00% vs 1.90%), living in poverty (32.30% vs 10.00%), and without a general educational development equivalent (28.00% vs 12.00%) compared with low-incarceration neighborhoods. In fully adjusted models, high-incarceration neighborhoods had a 13% higher IRR of preterm birth (IRR, 1.13; 95% CI, 1.08-1.18), 45% higher IRR of very preterm birth (IRR, 1.45; 95% CI, 1.24-1.71), 125% higher IRR of extremely preterm birth (IRR, 2.25; 95% CI, 1.59-3.18), 10% higher IRR of low birth weight (IRR, 1.10; 95% CI, 1.05-1.16), and 52% higher IRR of very low birth weight compared with low-incarceration neighborhoods (IRR, 1.52; 95% CI, 1.28-1.81).Conclusions and RelevanceNeighborhood incarceration rate was positively associated with adverse birth outcomes, particularly those associated with infant mortality. Black people were significantly more likely to live in high-incarceration neighborhoods, suggesting that mass incarceration may contribute to racial disparities in birth outcomes.

Abstract:

In the United States, the overall teen birth rate has been decreasing. In 1991, the teen birth rate was 61.8 births for every 1,000 teen females, but in 2014, the same overall rate decreased to 24.2 births for every 1,000 teen females. Unfortunately, this decrease has not reflected equally across all the races/ethnic groups. In 2014, the teen birth rate for Hispanics was 38 births per 1,000 teen females. The NASN is aware about the disparities on teen birth among racial/ethnical groups and has released a specific statement about the role of school nurses on the improvement of pregnancy outcomes. This article explains the cultural, linguistic, and educational barriers faced by Hispanic teens with limited English proficiency when preventing pregnancy and describes the development and implementation of a sexual and reproductive health education curriculum. The implications for school nurses will be discussed.

Abstract:

In this research, we attempt to discover patterns that describe and predict the birth rate in Mexico by using data mining techniques based on relevant demographic and economic information about Mexico. More than twelve million births data obtained from the General Directorate of Health Information in the period 2008-2013 were analyzed. The acquired knowledge allows us to say that in Mexico the birth rate is affected by the social welfare, education and marginality at county level. Due to the diversity of the population and the large number of socioeconomic factors involved in Mexican society, it is difficult to find general impact factors for this issue. The results of this research are not intended to be definitive but its aim is to provide indicators that may influence decisions about birth control in Mexico.

BackgroundAlthough within Latin America Chile has one of the lowest birth rates among adolescents, it has a high rate in comparison to other developed nations.AimTo explore trends in birth rates among adolescents by selected demographics in Chile.MethodsThe national trend in birth rates was examined for women aged 15–19 years between 1992 and 2012. The birth rates for regions and communes were calculated using birth and census data and were analysed to determine its relationship to the regional or communal poverty rate, which were obtained from the Casen Survey. Differences in educational attainment were explored among adolescents with first-order and second-order or higher births using the Chi-square test.ResultsThe birth rate among adolescents has experienced a 25% decline in the past 20 years. Cross-regional variance in birth rates could not be explained by poverty rates. Within the Metropolitan Region, there is a positive correlation between poverty and adolescent birth rates. Among adolescents giving birth, 67% had completed 10–12 years of school at birth, but there is a significant difference in educational attainment between girls with a first-order and those with a higher-order birth.ConclusionsIn Chile, the adolescent birth rate varies greatly among regions and communes. This study found that urban and wealthy areas had lower birth rates than poor and rural ones, and that girls with a first-order birth had completed more years of school than girls with higher-order births.

Abstract:

Preterm birth rate depending on parental educational level in recent years has not been surveyed in Japan. In this study, we showed the trend in preterm birth rate depending on parental educational level from 2000 to 2020 by linking data from the Census regarding individuals’ educational level and parents in birth data of the vital statistics. Four types of parental educational level, namely junior high school, high school, technical school or junior college, and university or graduate school, were compared. Slope and relative indexes of inequality for preterm birth by educational level were computed by binomial models. Data on 3,148,711 births and 381,129,294 people were used in the analysis, and data on 782,536 singleton births were used after data linkage. The preterm birth rate (%) for junior high school graduate mothers and fathers was 5.09 and 5.20 in 2020, respectively. Contrarily, the preterm birth rate (%) for parents who graduated from a university or graduate school was 4.24 for mothers and 4.39 for fathers, and the rate tended to increase as educational level decreased, irrespective of parental gender. Results of inequality indexes showed that a statistically significant inequality by parental educational level persisted from 2000 to 2020.

Abstract:

Objective. To examine predictors of pregnancy and infant outcomes, including maternal race/ethnicity. Design. Prospective and observational follow-up of high-risk pregnancies and births. Participants. Three hundred fifty-four mothers and their preterm and/or high-risk live-born neonates were closely followed in three tertiary care centers from the prenatal to postnatal periods for potential high-risk and/or preterm births that required neonatal resuscitations. Major Outcome Measures. Pregnancy complications, birth complications, and infant outcomes were examined in conjunction with maternal factors, including preexisting health problems, health behaviors (smoking, alcohol consumption, prenatal visits), and the birth setting (tertiary care centers or community hospitals). Results. About 22% of these infants were transferred into the tertiary care centers from the community hospitals right after birth; the rest were born in the centers. According to regression analyses, predictors of the birth setting were race (White vs. non-White), maternal health behaviors, pregnancy complications, fetal distress, and the presence of congenital defects for infants (p < .001). Predictors for fetal distress included race (Whites) and pregnancy-induced hypertension (p < .003). Predictors for lower birth weight included race (non-Whites), maternal cigarette smoking, pregnancy complications, fetal distress, and congenital defects (p < .001). Infant mortality rate was 3.9% for these high-risk infants, with the highest rate in infants born to Black mothers (8%). Conclusions. There are obvious health disparities among White and non-White women experiencing high-risk pregnancies and births. Future studies are needed to develop interventions targeted to different racial/ethnic groups during pregnancy to reduce preterm and high-risk births.

Abstract:

Background and Objective. In Latvia, the mean age of women giving birth increased from 27.3 in 2000 to 29.0 years in 2010 during the last 11 years. The aim of this study was to report on major congenital anomalies of newborns at birth by the maternal age and to compare the mean maternal age by different diagnosis subgroups and maternal and neonatal characteristics. Material and Methods. A cross-sectional retrospective study with the data from the Medical Birth Register (2000–2010) was carried out. The live birth prevalence rate was calculated for the subgroups of major congenital anomalies per 10 000 live births by the maternal age. Results. The live birth prevalence rate of major congenital anomalies during the period 2000– 2010 was 211.4 per 10 000 live births. The prevalence rate increased depending on the maternal age. Congenital heart defects, limb defects, and urinary system anomalies were the most common anomalies. The study results showed an age-related risk of abdominal wall defects, orofacial clefts, and chromosomal anomalies. There were significantly higher proportions of preterm births, newborns with low birth weight, and complications during pregnancy among mothers aged 35 years and more. Conclusions. The data on congenital anomalies from the Latvian Medical Birth Register can be used for the assessment of epidemiology of congenital anomalies. The results of this retrospective study showed a decrease in the live birth prevalence rate of major congenital anomalies despite an increase in the mean age of mothers in Latvia.

Abstract:

The world’s main indicator of children’s health and general development is the infant mortality rate for infant under the age of five. Infant mortality is the term used to describe the death of a child before their first birthday. The infant mortality rate (IMR), which is the number of deaths of infants under one year of age per 1,000 live births, can be used to describe the prevalence of infant mortality in a population. Comparing the death rate of children under the age of five is the child mortality rate, commonly referred to as the under-five mortality rate. Nigeria, one of the nations with a high under-five mortality rate of 117 per 1,000 live births in 2019, is among those nations. The nation is among the top five nations with the highest mortality rate for children under five in 2019. This study aims to model infant mortality(Live birth and Still birth) rate using time series models and to predict the mortality rate using these models. Adeoyo Maternity Hospital Yemetu in Ibadan provided the data for this study. The data set is a monthly data and also a secondary data span for a period of 12 years (2009 to 2020). The time plot showed visual inspection and non-stationarity. Differencing was done and the unit root test performed for the purpose of comparison thereafter. Augmented-Dickey Fuller test and Phillip Perron unit root test was further tested for the establishment of stationarity in order to the main objectives. Three time series methods are the Autoregressive Integrated Moving Average Model(ARIMA), Exponential Smoothing and the Holt-Winters Method were used to model and predict the infant mortality rate data. The result shows that ARIMA order=c(0,0,1) with zero (0) mean for stillbirth and ARIMA order=c(1,0, 2) for live birth with the smallest AIC = (9.102 and 13.991). Akaike Information Criterion(AIC) values of (9.289, 14.139) and (9.102, 13.991) for live birth and still birth, respectively, were derived by exponential smoothing and Holtwinters technique. This means that Holtwinters' technique, which yielded the lowest AIC when compared to ARIMA and exponential smoothing, is the most accurate predictor of both stillbirth and live birth data. Given the high mortality rate for children under the age of five, it is crucial for the government to place more of an emphasis on health issues and to solve the problems plaguing Nigeria's child health care system.

Abstract:

Many scholars have previously studied the birth rate and its development, but there are still gaps in the research on which factors play a dominant role in the birth rate. Therefore, this paper will provide a clear study of this issue, using China as an example to help major countries solve the problem of low birth rates and economic development. The population issues caused by low birth rate were researched and the main factors for birth rate were found from research. The decisive factors that determine the birth rate in China were analyzed. The link between birth rate and economic development is examined. This study figures out that the two main factors that influence the birth rate are the divorce rate and the female employment rate. There is a relatively strong correlation between the birth rate and economic development. The formula and the principle of Vector Autoregressive (VAR), Bayesian Information Criterion (BIC) and Times Series Graphical lasso (TSGlasso), were researched and used.

Abstract:

Recently, there has been a significant increase in the rate of multiple births in most developed countries. However, few population-based studies have been conducted in China regarding the epidemiology of twin births in recent years. We performed a descriptive analysis of twin births from 1993 to 2005 using data from a population-based perinatal care program in southeast China. The twin birth rate in southeast China was 0.65%, and the twin birth rates from 1993 to 2005 fluctuated between 0.60% and 0.70%. During the three periods of 1993–1996, 1997–2000, and 2001–2005, the twin birth rate increased from 0.57% to 0.71% in urban areas (p = .005) and from 0.59% to 0.68% in mothers who had an education level of high school or higher (p = .046). After 2000, the twin birth rate of primiparae 30 years of age and older significantly increased from 0.72% to greater than 1.20%. We concluded that the twin birth rates in southeast China from 1993 to 2005 stayed constant in the overall population but increased in certain subgroups of women, presumably due to increased use of fertility treatment and the development of assisted reproductive technology.

Abstract:

AbstractBackgroundThe aetiology of conotruncal heart defects is poorly understood and the birth prevalence varies geographically. The known risk factors for developing conotruncal heart defects are as follows: CHD in siblings, genetic chromosomal abnormalities, paternal age >30 years, high parity, low birth weight, prematurity, and maternal diabetes.ObjectiveThe aim of this study was to characterise conotruncal heart defects, birth prevalence, mortality, and morbidity in the population of southern Israel, of whom 75% are Jewish and the rest are mostly Bedouin Arabs.MethodsThe data were obtained from Soroka University Medical Center database of births and newborns. Conotruncal heart defects cases were identified by ICD9 codes.ResultsDuring 1991–2011, there were 247,290 singleton live births and 393 conotruncal heart defects in Soroka University Medical Center. The birth prevalence per 10,000 live births of tetralogy of Fallot, transposition of the great arteries, and truncus arteriosus was 9.5, 5, and 1.8, respectively. In the multivariate analysis, Bedouin descent (adjusted odds ratio 2.40, p<0.001), maternal age >35 years (1.66, p=0.004), and siblings with congenital heart defects (1.98, p=0.005) were associated with tetralogy of Fallot, and Bedouin descent (1.61, p=0.05), siblings with congenital heart defects (2.19, p=0.004), and diabetes mellitus (7.15, p<0.001) were associated with transposition of the great arteries. In a univariate analysis, Bedouin descent (p=0.004) and congenital heart defects in siblings (p<0.001) were associated with truncus arteriosus.ConclusionWe observed higher birth prevalence of conotruncal heart defects compared with the birth prevalence reported worldwide, specifically among the Bedouins, a population characterised with high consanguinity rate. Therefore, genetic counselling and early fetal echocardiograms should be encouraged, especially in high consanguinity rate populations. Naturally, further educational efforts are needed in order to decrease consanguinity and its related consequences.

Abstract:

ObjectivesTo update the WHO estimate of preterm birth rate in China in 1990–2016 and to further explore variations by geographic regions and years of occurrence.DesignSystematic review and meta-analysis.Data sourcesPubmed, Embase, Cochrane Library and Sinomed databases were searched from 1990 to 2018.Eligibility criteriaStudies were included if they provided preterm birth data with at least 500 total births. Reviews, case–control studies, intervention studies and studies with insufficient information or published before 1990 were excluded. We estimated pooled incidence of preterm birth by a random effects model, and preterm birth rate in different year, region and by livebirths or all births in subgroup analyses.ResultsOur search identified 3945 records. After the removal of duplicates and screening of titles and abstracts, we reviewed 254 studies in full text and excluded 182, leaving 72 new studies. They were combined with the 82 studies included in the WHO report (154 studies, 187 data sets in total for the meta-analysis), including 24 039 084 births from 1990 to 2016. The pooled incidence of preterm birth in China was 6.09% (95% CI 5.86% to 6.31%) but has been steadily increasing from 5.36% (95% CI 4.89% to 5.84%) in 1990–1994 to 7.04% (95% CI 6.09% to 7.99%) in 2015–2016. The annual rate of increase was about 1.05% (95% CI 0.85% to 1.21%). Northwest China appeared to have the highest preterm birth rate (7.3%, 95% CI 4.92% to 9.68% from 1990 to 2016).ConclusionsThe incidence of preterm birth in China has been rising gradually in the past three decades. It was 7% in 2016. Preterm birth rate varied by region with the West having the highest occurrence.

Abstract:

The COVID 19 pandemic represents a major stress factor for non-infected pregnant women. Although maternal stress during pregnancy increases the risk of preterm birth and intrauterine growth restriction, an increasing number of studies yielded no negative effects of COVID 19 lockdowns on pregnancy outcome. The present study focused on pregnancy outcome during the first COVID 19 lockdown phase in Austria. In particular, it was hypothesized that the national lockdown had no negative effects on birth weight, low birth weight rate and preterm birth rate. In a retrospective medical record-based single center study, the outcome of 669 singleton live births in Vienna Austria during the lockdown phase between March and July 2020 was compared with the pregnancy outcome of 277 live births at the same hospital during the pre-lockdown months of January and February 2020 and, in addition, with the outcome of 28,807 live births between 2005 and 2019. The rate of very low gestational age was significantly lower during the lockdown phase than during the pre-lockdown phase. The rate of low gestational age, however, was slightly higher during the lockdown phase. Mean birth weight was significantly higher during the lockdown phase; the rates of low birth weight, very low birth weight and extremely low birth weight were significantly lower during the lockdown phase. In contrast, maternal gestational weight gain was significantly higher during the lockdown phase. The stressful lockdown phase in Austria seems to have no negative affect on gestational length and newborn weight among non-infected mothers.

Abstract:

The increasing obesity rates among women of reproductive age create a major obstetrical problem as obesity during pregnancy is associated with many complications, such as a higher rate of caesarean sections. This medical record-based study investigates the effects of maternal prepregnancy obesity on newborn parameters, birth mode, and miscarriage rate. The data of 15,404 singleton births that had taken place between 2009 and 2019 at the public Danube Hospital in Vienna were enrolled in the study. Newborn parameters are birth weight, birth length, head circumference, APGAR scores, as well as pH values of the arterial and venous umbilical cord blood. In addition, maternal age, height, body weight at the beginning and the end of pregnancy, and prepregnancy body mass index (BMI) (kg/m2) have been documented. The gestational week of birth, the mode of delivery, as well as the number of previous pregnancies and births, are included in the analyses. Birth length, birth weight, and head circumference of the newborn increase with increasing maternal BMI. Furthermore, with increasing maternal weight class, there tends to be a decrease in the pH value of the umbilical cord blood. Additionally, obese women have a history of more miscarriages, a higher rate of preterm birth, and a higher rate of emergency caesarean section than their normal-weight counterparts. Consequently, maternal obesity before and during pregnancy has far-reaching consequences for the mother, the child, and thus for the health care system.

Abstract:

Purpose – The purpose of this paper is to take a forecasting approach to examine the relationship between the US birth rate, marriage rate, and economic conditions (measured by both realized unemployment and expected unemployment). The expectation data come from the Michigan Surveys of Consumers. Design/methodology/approach – Utilizing monthly data, the authors first specify a univariate and three augmented autoregressive integrated moving average forecasting models for 1975-2001. Second, the authors use recursive estimation to generate multi-period forecasts of the birth rate for 2002-2008. Third, the authors employ standard evaluation methods to compare the predictive information content of the forecasts. Findings – First, the birth rate is pro-cyclical. Second, the marriage rate contains useful predictive information for the birth rate. Third, controlling for past information in the birth and marriage rates, both realized and expected unemployment embody useful information for predicting the birth rate. Fourth, expected unemployment is a more informative indicator than realized unemployment. Practical implications – The finding that the birth rate is pro-cyclical emphasizes the importance of economic stability in promoting childbearing, and the authors suggest counter-cyclical macroeconomic policy to shield families from major shocks. A stable economy, and especially one where families are optimistic about the future, promotes childbearing. The results also empower policymakers to analyze systematically the impact of changes to the structure of marriage on childbearing. Originality/value – This appears to be the first study that utilizes a forecasting approach to better understand the complex relationships between childbearing, marriage, and macroeconomic conditions.

Abstract:

Objectives: To analyze the seven metropolitan cities of twin birth rate per 100 births (TBR) from 2000 to 2019 in Korea.Methods: We used the 2000-2019 birth certificated data (3,949,097 births) of seven metropolitan cities from Statistics Korea. The data of extra-marital birth and information missing cases (maternal and paternal age and triplet birth) were excluded. The odds ratio and 95% confidence intervals were calculated using logistic regression to describe the regional variance of TBR adjusted for maternal age, age difference between couple and maternal educational backgrounds.Results: During this period (2000-2019 years), the highest TBR by region was observed in Ulsan and Seoul metropolitan city (3.0), and the lowest TBR in Deagu metropolitan city (2.6). The TBR increased by 275 percent from 1.74 in 2000 to 4.79 in 2019. During the period from 2000-2004 to 2015-2019, there was the highest increment of TBR in Ulsan metropolitan city (odds ratio: 1.78; 95% confidence interval: 1.64-1.92) and Busan metropolitan city (1.74; 1.65-1.83), and the lowest increment in Daegu metropolitan city (1.24; 1.17-1.31), after adjustment by logistic regression for demographic variables. During the period 2015-2019 years, there was a significant increase the odds ratio of TBR in Ulsan metropolitan city (1.39), Busan metropolitan city (1.33), Seoul metropolitan city (1.25) and Incheon metropolitan city (1.23), as compared with the TBR of Deagu metropolitan city.Conclusions: Over the past two decades, TBR have risen dramatically in metropolitan cities of Korea. Regional variance of TBR was observed among metropolitan cities in Korea. There is a need for more research to understand the socio-demographic and medical factors associated with regional differences. The national birth registration system needs to be reformed to monitor whether twin births are spontaneous or assisted pregnancy.
