Maternal health problems are one of the main indicators of health status, namely maternal mortality. Maternal mortality is still a major public health challenge around the world, including in Indonesia. The purpose of this study was to explore aspects of nutritional knowledge related to healthy food, balanced nutrition, exclusive breastfeeding and care during teenage pregnancy for Javanese ethnicity in Ponorogo, East Java. This type of research is qualitative with a phenomenological approach. This research was conducted in June - July 2020. The main informants in this study were pregnant women aged 10-19 years in the working area of the Balong Community Health Center, Ponorogo Regency. The source of the informants was determined by snowball sampling. The snowball sampling technique is a form of judgment sampling. Data collection is more emphasized through in-depth interviews (in-depth interviews), namely individual dialogue with informants obtained directly from pregnant women. The results of the study of 6 informants who were teenage pregnant women in the Balong PKM work area, Ponorogo Regency, all informants had underweight nutritional status (BMI / age) and Chronic Energy Deficiency (KEK). The knowledge explored in the form of: food for pregnant women, balanced nutrition, exclusive breastfeeding, risk of teenage pregnancy and pregnancy care. Based on the results of the interview, the informant said that foods that are good for pregnant women to consume are fruits, vegetables, milk and vitamins. Regarding balanced nutrition, all informants did not know at all what balanced nutrition for care during pregnancy, the informant said there was no difference in pregnancy care except health checks at health services, treatments such as maintaining cleanliness and regular exercise.

Abstract Background The diet of women in the preconception period and during pregnancy has a crucial impact on the development of the fetus and the health and metabolism of the baby. The energy requirements of a pregnant woman are higher, in addition, she should ensure an appropriate intake of particular nutrients and fluids. Folic acid supplementation is the most effective intervention in reducing congenital neural coil defects, as is stopping the consumption of alcohol and minimizing the intake of caffeinated beverages. Objectives The aim of the study was to assess the dietary habits, including caffeine and alcohol consumption, of women who are pregnant or preparing to conceive a child. Material and methods The study population comprised (n=539) Polish women. An original questionnaire was used, including a metric and questions about preparation for pregnancy and dietary habits. Responses were collected via the Internet in forums for pregnant women. Results Of the total of the women surveyed, 73% said they were preparing for pregnancy. 64% of the respondents began taking folic acid supplements and 49% had started vitamin and mineral supplementation. Only 21% of women said they had changed their diet in preparation for conceiving offspring. As many as 34% of women said they themselves had adequate knowledge about nutrition during pregnancy, while 43% searched for information on this topic on the Internet. The factor that differentiated the practiced eating habits to the greatest extent was the level of education. Conclusions Despite numerous recommendations, there are still many women who do not prepare for pregnancy and do not follow preconception recommendations. A large number of Polish women with lower education still do not take folic acid. It is necessary to educate the society also about harmful effects of alcohol on the developing fetus. Knowledge should be spread with the use of social media, because women often look for information about nutritional rules on the Internet.

Evidence from women working night shifts during pregnancy indicates that circadian rhythm disruption has the potential to adversely influence pregnancy outcomes. In the general population, chronodisruption with the potential to affect pregnancy outcomes may also be seen in those with high energy intakes in the evening or at night. However, maternal night eating during pregnancy remains understudied. This narrative review provides an overview of the prevalence, contributing factors, nutritional aspects and health implications of night eating during pregnancy. We derived evidence based on cross-sectional studies and longitudinal cohorts. Overall, night eating is common during pregnancy, with the estimated prevalence in different populations ranging from 15% to 45%. The modern lifestyle and the presence of pregnancy symptoms contribute to night eating during pregnancy, which is likely to coexist and may interact with multiple undesirable lifestyle behaviors. Unfavorable nutritional characteristics associated with night eating have the potential to induce aberrant circadian rhythms in pregnant women, resulting in adverse metabolic and pregnancy outcomes. More research, particularly intervention studies, are needed to provide more definite information on the implications of night eating for mother-offspring health.

Pregnancy in women affected by chronic kidney disease (CKD) has become more common in recent years, probably as a consequence of increased CKD prevalence and improvements in the care provided to these patients. Management of this condition requires careful attention since many clinical aspects have to be taken into consideration, including the reciprocal influence of the renal disease and pregnancy, the need for adjustment of the medical treatments and the high risk of maternal and obstetric complications. Nutrition assessment and management is a crucial step in this process, since nutritional status may affect both maternal and fetal health, with potential effects also on the future development of adult diseases in the offspring. Nevertheless, few data are available on the nutritional management of pregnant women with CKD and the main clinical indications are based on small case series or are extrapolated from the general recommendations for non-pregnant CKD patients. In this review, we discuss the main issues regarding the nutritional management of pregnant women with renal diseases, including CKD patients on conservative treatment, patients on dialysis and kidney transplant patients, focusing on their relevance on fetal outcomes and considering the peculiarities of this population and the approaches that could be implemented into clinical practice.

In recent years there has been a deterioration in demographic indicators: a decrease in the birth rate, an increase in adult mortality, etc., due to numerous causes. In this context, the article addresses demographic issues related to subcultures and ideologies, such as childfree. The main characteristics of people classified as rejecters, aficionados, refusers, and postponers are discussed. We present the first results of a study conducted at the Khimki regional hospital. The study included 25 pregnant women. The survey results showed that most were planning a pregnancy before 30. A survey of expectant mothers indicated a positive attitude towards breastfeeding. The article discusses the issues of breastfeeding as an essential stage in forming a child's immunity and the factors of breastfeeding success. Women's nutrition during pregnancy and breastfeeding should be diverse and rich in vitamins and micronutrients. Special maternal drinks, such as Amalthea, based on New Zealand goat milk, can benefit breastfeeding. In the absence of breast milk, the selection of formula for the baby is one of the most challenging issues. It is important that the infant formula meet the child's nutritional needs to the maximum extent possible, including the functional milk components. For instance, the Nanny formula is based on New Zealand goat milk, using a single heat treatment process without separating milk into fractions, which preserves the native functional components of goat milk (oligosaccharides, nucleotides, milk fat).

Thesis (MVoeding)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: Introduction: Heavy alcohol consumption during pregnancy is teratogenic.49-51 A woman’s nutritional requirements increase during pregnancy.4 The dangers of heavy drinking in the presence of malnutrition may put the fetus at a further disadvantage to normal development and life. Objectives: To determine the nutritional status of pregnant women in relation to alcohol consumption during pregnancy, and pregnancy outcome. To relate the combined effect of maternal alcohol consumption and nutritional status to pregnancy outcome. Study design: Prospective, longitudinal and cohort. Study population: Pregnant women attending Hanover Park MOU for pre-natal care. They were classified as subjects (heavy drinkers) or controls (light drinkers or abstainers), and 15 pairs were matched according to race, parity and gestational age at the onset of their participation in the study. Methodology: A skilled FARR worker determined the alcohol consumption of the individuals through a validated questionnaire, whilst the investigator gathered the study data blinded to the participants’ alcohol consumption status. The investigator conducted three interviews with the pregnant individuals. Anthropometrical, clinical and biochemical investigations were done and questionnaires completed to determine dietary intake, sociodemographics, health and eating habits. An experienced FARR paediatrician examined the newborns, assessing their anthropometric status, health and the presence of any alcohol-related signs. Results: The nutritional status of the matched subjects and controls did not differ significantly in terms of dietary intake, anthropometric or clinical assessment. There were significant differences between the 2 groups’ serum vitamin A values (p<0.0097). Significant associations were found between the mother and newborn data; specifically energy intake and gestational age at birth (p<0.0083), MUAC and birth weight (p<0.04), and weight gain and weight for age (p<0.0056). The participants’ energy intake also had a significant correlation with their weight gain during pregnancy (r=0.0389, p<0.01). The prevalence of FAS in the total population was 6.67%; a finding that confirms previously reported data in nearby Wellington, Western Cape.49 Conclusion: Some mothers’ good nutritional status did not protect their offspring against alcohol’s teratogenic effects. Nutritional status did have a few statistical significant effects on pregnancy. However, the investigator is of the opinion that the few significant findings were not enough to accept or reject the hypothesis; therefore, making the results inconclusive.
AFRIKAANSE OPSOMMING: Inleiding: Swaar alkoholgebruik tydens swangerskap is teratogenies.49-51 Vroue se voedingsbehoeftes verhoog met swangerskap.4 Die gevare van swaar alkoholgebruik in die teenwoordigheid van wanvoeding mag die fetus verhoed om normal te ontwikkel en groei. Doelwitte: Om die voedingstatus van swanger vroue te bepaal in verhouding met alkoholgebruik tydens swangerskap, en die swangerskapsuitkoms. Asook om die gekombineerde effek van die moeder se voedingstatus en alkoholgebruik op haar swangerskapsuitkoms te bepaal. Studie-ontwerp: Prospektief, longitudinaal en kohort. Studiepopulasie: Swanger vroue wat Hanover Park MOU besoek vir voorgeboorte sorg. Hulle is of as toetslinge (swaar drinkers) of as kontroles (ligte drinkers of geheelonthouers) geklassifiseer, en 15 pare is gepaar na aanleiding van ras, pariteit en gestasionele ouderdom by die aanvang van deelname aan die studie. Metodologie: ‘n Ervare SAVN lid het die individue se alkoholgebruik bepaal deur middel van ‘n gevalideerde vraelys. Die navorser was geblind vir die individue se alkoholgebruik. Die navorser het drie onderhoude gevoer met elke individu. Antropometriese, kliniese en biochemiese ondersoeke is gedoen. Vraelyste is voltooi om dieetinname, gesondheid, sosiodemografiese en eetgewoonte- inligting te versamel. ‘n Ervare SAVN pediater het alle pasgeborenes ondersoek om hulle antropometriese status, gesondheid en die teenwoordigheid van enige alkohol-verwante tekens te bepaal. Resultate: Die voedingstatus van die gepaarde toets-en kontrolegroepe het nie beduidend verskil in terme van dieetinname, antropometriese of kliniese evaluering nie. Daar was ‘n beduidende verskil tussen die 2 groepe se serum vitamien A vlakke (p<0.0097). Beduidende assosiasies is gevind tussen die moeder en pasgebore se data; naamlike tussen energie-inname en gestasionele ouderdom by geboorte (p<0.0083), bo-armomtrek en geboortegewig (p<0.0056), en gewigstoename tydens swangerskap en die baba se gewig vir ouderdom (p<0.0056). Die deelnemers se energie-inname het ook ‘n beduidende positiewe korrelasie met hul gewigstoename tydens swangerskap gehad (r=0.0389, p<0.01). Die prevalensie van FAS in die totale populasie was 6.67%; wat ook gevind is onlangs in die nabygeleë Wellington, Weskaap.49 Gevolgtrekking: Sommige moeders se goeie voedingstatus het nie hul kinders teen alkohol se teratogeniese effekte beskerm nie. Voedingstatus se effek op swangerskapsuitkoms was statisties beduidend in ‘n paar gevalle. Tog is die navorser van mening dat daar nie genoeg beduidende bewyse is om die nulhipotese te aanvaar of verwerp nie; dus is die gevolgtrekking onopgelos.

Background A well-balanced nutritious diet is important for the pregnant woman and the growing fetus, as well as for their future health. Poor nutrition results from both over-consumption of energy-rich foods which can lead to a higher weight gain than is healthy and under-nutrition of essential nutrients. Food intake is regulated in complex biological systems by many factors, where steroid hormone is one factor involved. The overall aim of this thesis is to describe dietary intake, vitamin D levels, dietary information and dietary changes, and to study the relation between allopregnanolone and weight gain during pregnancy and postpartum. Methods Study I was a qualitative study with focus group interviews with 23 pregnant women. The text was analysed with content analysis. Study II was a quantitative cross-sectional study conducted in early pregnancy (n=209) with a reference group (n=206). Self-reported dietary data from a questionnaire was analysed using descriptive comparative statistics and a cluster analysis model (Partial Least Squares modelling). Study III had a quantitative longitudinal design. Vitamin D concentrations were analysed in 184 women, collected on five occasions during pregnancy and postpartum. Descriptive comparative statistics and a linear mixed model were used. Study IV was a quantitative longitudinal study with 60 women. Concentrations of allopregnanolone were analysed in gestational week 12 and 35. Descriptive and comparative statistics as well as Spearman’s correlation (rho) were used to describe the relationship between weight gain and allopregnanolone concentrations. Results The focus group interviews showed that women wanted to know more about different foods to reduce any risk for their child but the information about foods was partly up to themselves to find out. They expressedfeelingsof insecurityand guiltif they accidentallyate something“forbidden”. The recommendationswere followedas best as possiblealong withcommon sense todeal with dietchanges. The main themes were “Finding out by oneself”, “Getting professional advice when health problems occur”, “Being uncertain” and “Being responsible with a pinch of salt”. Some differences in the dietary patterns were found among the pregnant women compared to references, with less, vegetables (47 g/day), potatoes/rice/pasta (31 g/day), meat/fish (24 g/day) and intake of alcohol and tobacco/snuff but a higher intake of supplements. Bothpregnant women and referenceshad intakes offolatethrough diet45% (pregnant) and 22% (references) lower than current recommendations(500vs400g/day). Vitamin Dintake was34% lower than the recommendationsof 10mg/day. At least a third of the participants had insufficient plasma levels below 50 nmol/L of vitamin D. Season was a strong factor influencing the longitudinal pattern. Gestational week, season, total energy intake, dietary intake of vitamin D, and multivitamin supplementation over the previous 14 days were factors related to vitamin D levels. A correlation betweenallopregnanoloneconcentrations ingestationalweek 35and weight gainin weeks12–35was seen (p = 0.016). Therewas alsoa correlation betweenthe increase inallopregnanolone(weeks12–35) andweight gain(see above) (p = 0.028). Conclusions Dietary recommendations were described as contradictory and confusing and the dietary advice felt inadequate. The women faced their diet changes and sought information on their own but would have wished for more extensive advice from the midwife. The intake of vitamins essential for pregnancy was lower than recommended, which is also confirmed by low plasma levels of vitamin D in at least one third of the pregnant women. Vitamin D levels peaked in late pregnancy. Aside from gestational week and season which were related to plasma levels, intake from foods and supplements also affected the levels. Reasons for weight gain are complex and depend on many factors. Allopregnanolone is a factor that was seen to relate to the weight gain of the studied pregnant women.Bakgrund En välbalanserad näringsrik kost är viktig för den gravida kvinnan och det växande fostret, så även för deras framtida hälsa. En bristfällig kost kan utgöras av både överförbrukning av energirika livsmedel vilket kan leda till högre viktuppgång än vad som är hälsosamt och bristande intag av viktiga näringsämnen. Kostintag regleras av komplexa biologiska system där flera faktorer är inblandade däribland steroidhormonet allopregnanolon. Det övergripande syftet med denna avhandling är att under och efter graviditet beskriva kostintag, vitamin D-nivåer, kostinformation och kostförändringar och att studera allopregnanolons relation till viktökning. Metod Studie I var en kvalitativ studie med fokusgruppsintervjuer med 23 gravida kvinnor. Texten analyserades med innehållsanalys. Studie II var en kvantitativ tvärsnittsstudie som genomfördes i tidig graviditet (n = 209) och med en grupp icke-gravida kvinnor (kontrollgrupp) (n=206). Självrapporterade kostdata från ett frågeformulär analyserades med beskrivande, jämförande statistik och en klusteranalysmodell (Partial Least Squares modellering). Studie III hade en kvantitativ longitudinell design. Vitamin D-koncentrationer analyserades hos 184 kvinnor, vid fem tillfällen under graviditeten och efter förlossningen. Beskrivande, jämförande statistik och en linjär mixad regressionsmodell användes. Studie IV var en kvantitativ longitudinell studie med 60 kvinnor. Koncentrationerna av allopregnanolon analyserades vid graviditetsvecka 12 och 35. Beskrivande och jämförande statistik samt Spearman’s korrelation användes för att beskriva samband mellan viktökning och koncentrationer av allopregnanolon. Resultat Intervjuerna i studie I visade att kvinnor ville veta mer om olika typer av mat för att minska en eventuell risk för sina barn men kostinformation var delvis upp till dem själva att ta reda på. De VIII uttryckte känslor av osäkerhet och skuld om de råkat äta något ”förbjudet”. Rekommendationerna följdes så väl som möjligt, tillsammans med sunt förnuft för att hantera kostförändringar. Huvudteman var ”Söka information på egen hand”, ”Få professionell rådgivning när problem uppstår”, ”Känna sig osäker” och ”Ta ansvar med en nypa salt”. I studie II kunde man se vissa skillnader i kostmönster bland de gravida kvinnorna jämfört med kontrollgruppen: mindre intag av grönsaker (47 g/dag), potatis/ris/pasta (31 g/dag), kött/fisk (24 g/dag) och alkohol och tobak/snus och ett högre intag av kosttillskott. Både gravida kvinnor och kontrollgruppen hade lägre intag av folsyra via kosten med 45 % (gravida) och 22 % (kontrollgruppen) än de gällande rekommendationer som är (500 resp 400 g/dag). I studie III såg man att inta et av vitamin D var 34 % lägre än rekommendationen på 10 µg/dag. Minst en tredjedel av deltagarna hade otillräckliga plasma nivåer av vitamin D, under 50 nmol/L. Årstid var en stark faktor som påverkar det longitudinella mönstret. Graviditetsvecka, säsong, totala energiintaget, intaget av vitamin D och multivitamintillskott under de senaste 14 dagarna var faktorer som relaterade till Dvitaminnivåer. I studie IV sågs ett samband mellan allopregnanolon-koncentrationer vid graviditetsvecka 35 och viktökning från vecka 12 till 35 (p = 0,016). Det sågs också ett samband mellan ökningen av allopregnanolon (vecka 12–35) och viktökningen (se ovan) (p = 0,028). Slutsatser Kostrekommendationer beskrevs som motsägelsefulla och förvirrande och kostråden de fick uppfattades som otillräckliga. Kvinnorna tog itu med sina kostförändringar och sökte information på egen hand men hade önskat mer omfattande råd från barnmorskan. Intaget av vitaminer viktiga för graviditeten var lägre än rekommendationerna, vilket också bekräftas av låga plasmanivåer av D-vitamin hos cirka en tredjedel av de gravida kvinnorna. D-vitaminnivåerna nådde en topp i slutet av graviditeten. Graviditetsvecka och säsong på året påverkade D vitaminnivåer, så även intag via mat och kosttillskott. Orsakertill viktökning är komplexa och beror på många faktorer. Allopregnanolon är en faktor som sågs relatera till viktökningen hos de undersökta gravida kvinnorna.

Testo completoAbstract (sommario):
This study was designed to measure the prevalence and nutritional impact of dairy product restriction in both pregnant and lactating women. Dairy product (DP) restriction was assessed in 2091 prenatal class attendees. Subsamples of 279 healthy pregnant and 175 exclusively breastfeeding women provided repeat 24-hour dietary recalls which were used to estimate nutrient intake and to assess dietary adequacy using adjusted nutrient distributions. Pregnancy outcome was recorded. Pregnancy. DP restriction was reported by 13.2% (95% CI: 12.7%,14.1%) of pregnant women. Significant differences were found in the proportion of restrictors (Rs, 20.8%) below the calculated EAR for adjusted protein intakes vs. nonrestrictors (NRs, 9.2%, chi 2 = 6.78, p = 0.009). Intake distributions of calcium and vitamin D were compared to their respective Als for descriptive purposes and were lower for Rs vs. NRs but dietary inadequacy could not be assessed. Infants of NRs weighed on average 120 g +/- 468.9 g more than those of Rs but this difference was not statistically significant (p = 0.06). However, in multiple regression analysis where maternal weight gain, age, education and pregravid weight were controlled for, restriction predicted a comparable loss in birthweight of 122.5 g's (p = 0.048) and vitamin D intakes were positively associated with fetal growth. Lactation. Restriction (≤250 ml milk/day) was reported by 23% (95% CI; 16%--29%) of exclusively lactating women. Protein was lower than the EAR for 60% of Rs and 37.8% of NRs (chi 2 = 6.22, p = 0.025). The proportion of Rs and NRs < EAR from diet differed for thiamin (15% vs. 0%, chi2 = 0.97, p < 0.001), riboflavin (15% vs. 1.5%, chi2 = 12.93, p < 0.001) and zinc (65.0% vs. 34.8%, chi2 = 11.6, p < 0.041). From diet and supplement intake vitamin D and calcium remained lower for Rs compared to NRs but inadequacy could not be assessed or compared. DP restriction was not associated with greater weight loss amo

This paper attempted to determine the effect that gastrointestinal discomforts, socioeconomic status, dietary knowledge and beliefs about foods to omit during pregnancy had on the nutritional status of pregnant women. Hemoglobin, upper arm muscle circumference, weight for height and eating patterns measured nutritional status. Twenty women in their second trimester of pregnancy, active duty or the dependent wife of an Air Force E-4 and below, were surveyed. Questionnaires and anthropometric measures were used. Pearson Product Moment Correlations and a canonical correlation were accomplished. Data analysis indicated a significant negative correlation between eating patterns and gastrointestinal discomfort. There was a significant positive correlation between beliefs about foods to omit and eating patterns. Significant negative correlations existed between dietary knowledge and military status, monthly grocery bill, and number of people fed.

Testo completoAbstract (sommario):
The nutritional status of 78 women was assessed during the third trimester of pregnancy. The study was conducted in military barracks in Sierra Leone with 39 adolescent women (<20 years) and 39 adult women (>20 years).Twenty-four hour dietary recall interviews and anthropometric measures were collected. Laboratory, clinical and physiological data were obtained from the subjects' medical records. The dietary analysis of the diets consumed by adolescent and adult women showed differences in the intakes of only calcium, phosphorous, potassium, selenium and sodium. The average diet consumed by the women was <2/3 the recommended guidelines for carbohydrate and <2/3 the Recommended Dietary Allowances for persons in the U.S. for kilocalories, protein, riboflavin, pyridoxine, folacin, pantothenic acid, cholesterol, calcium, iron, magnesium, phosphorous, sodium and zinc. The women consumed diets that were >100 percent of the RDA for vitamins A, C, E, niacin and selenium. Differences occurred in the infant birthweights and Apgar scores at 1, 5 and 10 minutes between women who had abnormal measures for hemoglobin, hematocrit, ketonuria, albuminuria, glycosuria and/or malaria parasites and the women who were healthy.Maternal weight gain, age and infant health status did not correlate. The average weight gain for all the women was 17.85 kg which is within the acceptable range recommended for pregnancy. Maternal weight-at-term, gestational age, triceps skinfolds, arm circumference, hemoglobin, hematocrit were correlated with infant birthweight, length and head circumference. Maternal hemoglobin and hematocrit further correlated with infant Apgar scores at 1, 5 and 10 minutes.Hemoglobin and hematocrit levels were very low for the average women in the study (X 9.7 g/dl and 29.7 percent respectively). The malaria reduced the infant birthweight by 431 g. Albuminuria and ketonuria were associated with reduced infant birthweight while modest glycosuria was associated with increased birthweight.Department of Home Economics

AbstractGlobally, the COVID-19 pandemic has disrupted the delivery of essential health services in general and reproductive, maternal, newborn, child health, and nutrition (RMNCHN) services in particular. The degree of disruption, however, varies disproportionately. It is more in low- and middle-income countries than in high-income countries. Focusing on India, the authors draw on various demand and supply side factors that hampered the provision of RMNCHN services and thus adversely affected many families across the country. Coupled with the gendered aspects of the social determinants of health, the pandemic intensified social vulnerabilities by impacting pregnant and lactating women and children the most. Modelling studies suggest that the progress India made over a decade on various maternal and child health and nutrition indicators may go in vain unless focused efforts are made to address the slide. Complementing government efforts to mitigate the health risks of the pandemic by strengthening health services, women-led initiatives played an important role in portraying how women’s collectives and women in leadership can be like a bridge over troubled waters in the times of a pandemic.

This chapter studies how the life-long nutritional status of a mother, from her own conception and throughout her life to the birth of her baby, impacts on the health and well-being of that baby. Indeed, the particular importance of the mother's nutrition in the months before conception is now recognized. Here the emphasis is on the achievement of appropriate body weight and optimal nutritional status (and stores) for the months ahead. Moreover, pre-pregnancy nutrition takes account of the needs of the very early stages of pregnancy (embryogenesis) when the woman may not know she is pregnant. Maternal nutrition also has a profound effect on all aspects of reproduction, including fertility. The chapter then considers lactation; during pregnancy, the mother's body prepares for lactation by storing some nutrients and energy.

Testo completoAbstract (sommario):
Abstract It is hypothesized that the risk of cardiovascular disease and diabetes in adult life is programmed in utero by specific patterns of abnormal fetal growth associated with maternal undernutrition. This hypothesis raises fundamental questions about patterns of fetal growth in utero and about the role of factors other than nutrition in fetal growth and development. An unambiguous concept of nutrition that relates to the mother’s diet, growth, and development in childhood, and her diet during pregnancy, facilitates the testing of precisely formulated hypotheses in work on nutrition, fetal growth and adult disease. Different patterns of fetal growth retardation in pregnancy form a continuum that depends mainly on the severity and timing of thenutritional or other insult. Growth failure in the third trimester tends to be asymmetrical, with weight loss but a relative sparing of fetal length. The hypothesis that nutritional insults in early pregnancy set the fetus on a low growth trajectory leading to symmetrical growth retardation is less securely based. The concept of nutritional programming is undoubtedly plausible in biological terms. However, a less discrete and deterministic model of programming is proposed, involving interactions between the maternal and fetal genotype, the mother’s environment and life style (including diet), her prepregnancy nutritional status, metabolism and physiology, the hormonal, metabolic and circulatory milieu which sustains fetal growth and the infant’s postnatal environment. The effects of prenatal nutrition on fetal growth in man depend on the timing of nutritional exposures in relation to critical periods of development and on interactions with the mother’s prepregnancy nutritional status and aspects of the mother’s metabolism and physiology such as glucose tolerance and blood pressure.

‘Cellular metabolism’ addresses the major biochemical pathways and processes of the cells of the body. These include the central metabolic pathways involved in energy production: the tricarboxylic acid or Krebs cycle, and ATP synthesis through the electron transport chain and oxidative phosphorylation (chemiosmotic theory). Metabolism of each of the major fuel sources is considered: lipids, carbohydrates, and proteins, including energy storage as fat and glycogen, and excretion of nitrogen via the urea cycle. The different cellular compartments for metabolism are explored, as is the integration and regulation of the metabolic processes in a number of conditions such as fasting and starvation, exercise, pregnancy, and diabetes. Finally in this chapter the clinical aspects of metabolism are discussed, including energy balance and nutrition, obesity, and inborn errors of metabolism.

Abstract Numerous recent studies have demonstrated associations between specific patterns of fetal and infant growth and coronary heart disease. In this chapter, we examine the potential long term health impacts of interventions to improve fetal and infant growth. Although the available evidence does not permit firm inference that reduced fetal or infant growth causes coronary heart disease, our discussion is based on the assumption that the reported associations are in fact causal. The magnitudes of the effect that interventions to improve fetal growth are likely to have on subsequent coronary heart disease were estimated using data from the Hertfordshire cohort. About 33% and 26% of coronary heart disease deaths among women and men, respectively, would be averted if all births weighed between 9 –9.5 lbs (3969 –4422 g). Most of this decline would occur secondary to increases in the birthweight of babies in the 7–8.5 lbs (3061 –3968 g) category. Simulations with more realistic assumptions based on the 1993 Canadian birth cohort show a marginal impact on subsequent coronary heart disease deaths. For instance, a 100 g increase in the birthweight of female and male babies would result in a 2.5% and a 1.9% decrease in coronary heart disease deaths, respectively. Various options for improving fetal growth were reviewed, including interventions to improve maternal nutrition before and during pregnancy, reduce smoking in pregnancy and improve other aspects of prenatal care. The effects of such interventions are likely to be relatively modest, at least in terms of their impacts on subsequent coronary heart disease. For instance, observational studies show that the mean birthweight reduction in smoking mothers is approximately 150 g, while clinical trials evaluating the effects of intervention to reduce smoking in pregnancy have reported mean birthweight increases ranging from 31 to 92 g. Other issues that must be considered before intervening to improve fetal growth include the potential for unintended (adverse) effects.

The production of animals has benefited significantly from the implementation of assisted reproductive technology. In breeding, marker systems are generally used for marker-aided selection (MAS). Marker-assisted selection is a procedure through which beneficial genes can be detected by the presence of marker genes. Marker assisted selection (MAS) is a type of indirect selection method in which a trait of interest is selected based on a marker related to the trait instead of the trait itself. To improve genetic evaluation and selection, all information gathered at markers and QTL will be blended with phenotypic data.The potential advantages of nuclear transfer cloning employing mammalian somatic cells are immense. However, in every species where actual clones have been developed, somatic cloning has been shown to be unsuccessful. High rates of foetal mortality and abortion can frequently be observed. The incomplete reprogramming of the somatic nuclei during the cloning process has been linked to these developmental abnormalities. Although a number of techniques have been employed, major advancements in nuclear transfer efficiency have not yet been made. Molecular biology is advancing at a pace never seen before these days. The ability to create transgenic animals is one of them. The first successful transgenic animal was a mouse. A few years afterwards saw the arrival of pigs, sheep, cattle, and rabbits. The effects of aberrant reprograming during pregnancy, the neo-natal stage, and development in the cloned generation are all part of the continuum known as the cloning syndrome. However, it does not seem to be passed on to successive generations after sexual reproduction.The majority of in vivo studies regarding somatic cell cloning in cows has concentrated on developing while pregnant and the neonatal phase.Broadly speaking, the primary initial three phases of artificial reproductive technologies (ARTs) - 1) artificial insemination (AI) and gamete and embryo sexing, 2) multiple ovulation and embryo transfer (MOET), and 3) in vitro fertilisation, or IVF, procedures - have developed into effective commercial uses that enable genetically-based growth in production, shortened generation intervals, disease control, and cost savings. The procedures included in the 4th phase of ART are considerably more experimental and include transgenesis, stem cell biology, and nuclear transfer (NT) cloning of embryonic or somatic cells. These technologies are totally reliant on earlier technological generations and are entwined with each other and the molecular tools that are currently accessible. However, a number of reproductive issues continue to prevent livestock from reproducing to their full potential, which has an impact on profitability and productivity. It is obvious that the use of these technologies as profitable endeavours will remain dubious if they are not combined with other aspects of animal production, like proper animal husbandry techniques, animal nutrition, and animal health.

Depression can result in changes in eating behavior and decrease the quality of eating. It has been shown that maternal depression during pregnancy can result in malnutrition, which can have adverse effects on the pregnancy and the offspring. There is currently no clear association between depression and diet; (2) Methods: Five hundred and forty-nine pregnant women recruited from Danyang Maternal and Child Health Hospital in Jiangsu Province participated in this study and were administered the Intuitive Eating Scale-2(IES-2), Edinburgh Post-natal Depression Scale (EPDS), Pregnancy Stress Scale (PPS), Self-rating Anxiety Scale (SAS), and Dietary Guidelines Adherence Index for Pregnant Women during Pregnancy (CDGCI-PW). The nutritional software collected dietary records for three consecutive days in mid-pregnancy to calculate dietary intake and nutrients that support energy production. The mediation analyses were conducted using SPSS 24.0 macro PROCESS; (3) Results: The relationship between depressive symptoms during pregnancy and diet quality was moderated primarily by two aspects of eating behavior, “Reliance on Hunger and Satiety Cues” (RHS) and “Body-Food Choice Congruence” (BFC). Depressive symptoms (EPDS scores) showed a negative correlation with RHS, BFC, and RHS, and BFC showed a positive correlation with diet quality, yielding a significant specific indirect effect. the multiple mediation model explained 14.7% of the variance in the diet quality; (4) Conclusions: Individual awareness of depression may influence the causal association between nutrition and depression. This study highlights the important role of eating behaviors during pregnancy in the relationship between depressive symptoms (EPDS scores) and diet quality and provides preliminary evidence for feasible ways pregnant women with depressive symptoms can improve diet quality, promote maternal and child health, and reduce depression.

Background: Dietary practices are an aspect of dietary quality that indicates general nutritional adequacy. Lack of diversified diet is a severe problem in the developing world, where diet are predominantly starchy staples with few animal products, seasonal fruits and vegetables. The nutritional status of a woman during pregnancy is important as a suboptimal diet impact negatively on the health of the mother, and the newborn. There is limited knowledge in the area of dietary practices and nutritional status of pregnancy factors affecting it among pregnant women despite evidence showing that maternal nutrition has important direct and /or indirect consequences for all other age cohorts. The study aimed to asses factors affecting dietary practices and nutritional status of pregnant adolescents. Method: Cross sectional analytic design was used and the study was carried out in Ol’Lessos village. A Sample size of 129 pregnant women was targeted with the first respondent being randomly selected and thereafter systemic sampling was used until the required sample was reached. Mid upper arm (MUAC) of the left arm of the respondents of the women were measured to determine the nutritional status. Data were collected using researcher administered questionnaires and focus group discussion guide. Data collected using 24-hour recall was analyzed by Nutrisurvey. Results: There were significant differences in the mean macronutrients and micronutrients with regard to the dds where respondents with a higher DDS (.> six) were more likely to have a higher macro and micronutrient intake compared with those who had a lower. The mean energy intake was 1909 Kcal +630 which is below the Recommended Daily Allowances (RDA)of 2400 kcal for pregnant women. Based on MUAC cut offs, 31.7 percent were malnourished (MUAC< 21.0 CM) while 68.3 percent of the respondents were normal (MUAC >21.0cm). MUAC was positively correlated with the socio-economic status. Based on the WHO cut offs,73.6 percent were anaemic. Regression showed that the age of the mother and the numbers of births were significant predictors of the MUAC of the pregnant women (p=0.001). Conclusion: It’s is recommended that guidelines for nutrition and diets be carried out through practical demonstrations in the community and health facilities. The findings of the study may be used by Ministry of Public Health and Sanitation (MOPHS) and other organizations to promote and implement programs aimed at improving dietary practices and nutrition status among pregnant in the county.

Testo completoAbstract (sommario):
Various unicellular algae produce omega-3 (w3) very-long-chain polyunsaturated fatty acids (VLC-PUFA), which are rarely found in higher plants. In this research and other studies from our laboratories, it has been demonstrated that the marine unicellular alga Nannochloropsis (Eustigmatophyceae) can be used as a reliable and high quality source for the w3 VLC-PUFA eicosapentaenoic acid (EPA). This alga is widely used in mariculture systems as the primary component of the artificial food chain in fish larvae production, mainly due to its high EPA content. Furthermore, w3 fatty acids are essential for humans as dietary supplements and may have therapeutic benefits. The goal of this research proposal was to understand the physiological and biochemical mechanisms which regulate the synthesis and accumulation of glycerolipids enriched with w3 VLC-PUFA in Nannochloropsis. The results of our studies demonstrate various aspects of lipid synthesis and its regulation in the alga: 1. Variations in lipid class composition imposed by various environmental conditions were determined with special emphasis on the relative abundance of the molecular species of triacylglycerol (TAG) and monogalactosyl diacylglycerol (MGDG). 2. The relationships between the cellular content of major glycerolipids (TAG and MGDG) and the enzymes involved in their synthesis were studied. The results suggested the importance of UDP-galactose diacylglycerol galactosyl (UDGT) in regulation of the cellular level of MGDG. In a current effort we have purified UDGT several hundredfold from Nannochloropsis. It is our aim to purify this enzyme to near homogeneity and to produce antibodies against this enzyme in order to provide the tools for elucidation of the biochemical mechanisms that regulate this enzyme and carbon allocation into galactolipids. 3. Our in vitro and in vivo labeling studies indicated the possibility that phosphatidylcholine (PC) and phosphatidylethanolamine (PE) are associated with desaturation of the structural lipids, whereas shorter chain saturated fatty acids are more likely to be incorporated into TAG. 4. Isolation of several putative mutants of Nannochloropsis which appear to have different lipid and fatty acid compositions than the wild type; a mutant of a special importance that is devoid of EPA was fully characterized. In addition, we could demonstrate the feasibility of Nannochloropsis biomass production for aquaculture and human health: 1) We demonstrated in semi-industrial scale the feasibility of mass production of Nannochloropsis biomass in collaboration with the algae plant NBT in Eilat; 2) Nutritional studies verified the importance algal w3 fatty acids for the development of rats and demonstrated that Nannochloropsis biomass fed to pregnant and lactating rats can benefit their offspring.
