    1995-08-28

    We describe the first case of a baby with maternal uniparental disomy of chromosome 2. Growth failure, hypothyroidism, and hyaline membrane disease were present at birth, and the first year of life was complicated by bronchopulmonary dysplasia. At age 14 months, motor and intellectual development were normal, but growth remained below the 10th centile. The baby was investigated for uniparental disomy because trisomy 2 mosaicism had been detected in a second trimester amniocentesis. This is the first reported case in which amniotic fluid chromosome mosaicism has been associated with uniparental disomy. Implications for prenatal diagnosis are considered. 26 refs., 4 figs.

    Fe deficiency anaemia during early pregnancy has been linked with low birth weight and preterm birth. However, this evidence comes mostly from studies measuring Hb levels rather than specific measures of Fe deficiency. The present study aimed to examine the association between maternal Fe status during the first trimester of pregnancy, as assessed by serum ferritin, transferrin receptor and their ratio, with size at birth and preterm birth. In the Baby VIP (Baby's Vascular health and Iron in Pregnancy) study, we recruited 362 infants and their mothers after delivery in Leeds, UK. Biomarkers were measured in maternal serum samples previously obtained in the first trimester of pregnancy. The cohort included sixty-four (18 %) small for gestational age (SGA) babies. Thirty-three babies were born preterm (9 %; between 34 and 37 weeks). First trimester maternal Fe depletion was associated with a higher risk of SGA (adjusted OR 2·2, 95 % CI 1·1, 4·1). This relationship was attenuated when including early pregnancy Hb in the model, suggesting it as a mediator (adjusted OR 1·6, 95 % CI 0·8, 3·2). For every 10 g/l increase in maternal Hb level in the first half of pregnancy the risk of SGA was reduced by 30 % (adjusted 95 % CI 0, 40 %); levels below 110 g/l were associated with a 3-fold increase in the risk of SGA (95 % CI 1·0, 9·0). There was no evidence of association between maternal Fe depletion and preterm birth (adjusted OR 1·5, 95 % 0·6, 3·8). The present study shows that depleted Fe stores in early pregnancy are associated with higher risk of SGA. PMID:25946517

    While the World Health Organization's Baby-Friendly Hospital Initiative has increased breastfeeding duration and exclusivity, a survey found that only 8.5 % of maternity hospitals in 31 developed countries could be designated baby-friendly. Baby-friendly breastfeeding support is sometimes criticized as mother unfriendly. This study examined whether baby-friendly breastfeeding support was associated with breastfeeding satisfaction, duration, and exclusivity among Japanese mothers. In this cross-sectional study, 601 breastfeeding Japanese mothers completed questionnaires at their infants' 4-month health checkups at two wards in Yokohama, Japan; 363 were included in the analysis. Baby-friendly breastfeeding support was measured based on the WHO's "Ten Steps to Successful Breastfeeding." We measured satisfaction using two subscales of the Japanese version of the Maternal Breastfeeding Evaluation Scale. The association of baby-friendly support with maternal satisfaction was assessed using multiple linear regression, while the prevalence ratios (PRs) for breastfeeding were estimated using Poisson regression. Mothers were stratified by prepartum exclusive breastfeeding intention (yes, n = 256; no, n = 107). Mothers who experienced early skin-to-skin contact with their infants were more likely to report breastfeeding satisfaction than those who did not. Among mothers without exclusive breastfeeding intention, those who were encouraged to feed on demand were more likely to be breastfeeding without formula at 1 month (PR 2.66 [95 % CI 1.32, 5.36]) and to perceive breastfeeding as beneficial for their baby (regression coefficient = 3.14 [95 % CI 0.11, 6.17]) than those who were not so encouraged. Breastfeeding satisfaction was a useful measure of breastfeeding outcome. Early skin-to-skin contact and encouragement to feed on demand in the hospital facilitate breastfeeding satisfaction.

    1994-01-01

    Records of the diets of 513 London mothers towards the end of the first trimester of pregnancy have been reported previously to show the maternal nutritional intakes associated with birthweight in the optimum range, which may be assumed to approximate to basic maternal needs for reproduction. The diets associated with low birthweight and small head size were also recorded and were found to be inferior. The present paper shows social class gradients for baby size and 35 essential dietary components, providing an indication of which basic maternal nutritional needs were not always met. There was no social class gradient for intake of total energy, or the energy carriers carbohydrate and fat. There were, however, statistically highly significant social class gradients for intake of protein, seven minerals and six B-vitamins, all of which were also highly significantly correlated with birthweight. Maternal intake of these 14 components of diet fell progressively as birthweight fell, but only for the mothers of smaller babies below 3270g, the median for the study. Further increase of maternal intakes of any nutrient by mothers whose babies were above median did not apparently further increase birthweight. The social and medical problem presented by maternal nutrition is that of a minority of women who enter pregnancy with qualitatively inadequate nutritional status. This minority is found in all social classes but increases from social class I to V, and further still among single mothers. The women comprising this minority eat foods not meeting basic maternal needs for a range of nutrients characteristic of whole grains, vegetables and fruit and dairy produce, which may partly be explained by their high cost.

    ABSTRACT This report synthesizes evidence about innate hormonally mediated physiologic processes in women and fetuses/newborns during childbearing, and possible impacts of common maternity care practices and interventions on these processes, focusing on four hormone systems that are consequential for childbearing. Core hormonal physiology principles reveal profound interconnections between mothers and babies, among hormone systems, and from pregnancy through to the postpartum and newborn periods. Overall, consistent and coherent evidence from physiologic understandings and human and animal studies finds that the innate hormonal physiology of childbearing has significant benefits for mothers and babies. Such hormonally-mediated benefits may extend into the future through optimization of breastfeeding and maternal-infant attachment. A growing body of research finds that common maternity care interventions may disturb hormonal processes, reduce their benefits, and create new challenges. Developmental and epigenetic effects are biologically plausible but poorly studied. The perspective of hormonal physiology adds new considerations for benefit-harm assessments in maternity care, and suggests new research priorities, including consistently measuring crucial hormonally mediated outcomes that are frequently overlooked. Current understanding suggests that safely avoiding unneeded maternity care interventions would be wise, as supported by the Precautionary Principle. Promoting, supporting, and protecting physiologic childbearing, as far as safely possible in each situation, is a low-technology health and wellness approach to the care of childbearing women and their fetuses/newborns that is applicable in almost all maternity care settings.

    Objective To assess the coming challenges of caring for large numbers of frail elderly as the Baby Boom generation ages. Study Setting A review of economic and demographic data as well as simulations of projected socioeconomic and demographic patterns in the year 2030 form the basis of a review of the challenges related to caring for seniors that need to be faced by society. Study Design A series of analyses are used to consider the challenges related to caring for elders in the year 2030: (1) measures of macroeconomic burden are developed and analyzed, (2) the literatures on trends in disability, payment approaches for long-term care, healthy aging, and cultural views of aging are analyzed and synthesized, and(3)simulations of future income and assets patterns of the Baby Boom generation are developed. Principal Findings The economic burden of aging in 2030 should be no greater than the economic burden associated with raising large numbers of baby boom children in the 1960s. The real challenges of caring for the elderly in 2030 will involve: (1) making sure society develops payment and insurance systems for long-term care that work better than existing ones, (2) taking advantage of advances in medicine and behavioral health to keep the elderly as healthy and active as possible, (3) changing the way society organizes community services so that care is more accessible, and (4) altering the cultural view of aging to make sure all ages are integrated into the fabric of community life. Conclusions To meet the long-term care needs of Baby Boomers, social and public policy changes must begin soon. Meeting the financial and social service burdens of growing numbers of elders will not be a daunting task if necessary changes are made now rather than when Baby Boomers actually need long-term care.

    Background In animal studies, iron deficiency during pregnancy has been linked to increased offspring cardiovascular risk. No previous population studies have measured arterial stiffness early in life to examine its association with maternal iron status. Objective This study aimed to examine the association between maternal iron status in early pregnancy with infant brachio-femoral pulse wave velocity (PWV). Methods The Baby VIP (Baby's Vascular Health and Iron in Pregnancy) study is a UK-based birth cohort which recruited 362 women after delivery from the Leeds Teaching Hospitals postnatal wards. Ferritin and transferrin receptor levels were measured in maternal serum samples previously obtained in the first trimester. Infant brachio-femoral PWV was measured during a home visit at 2–6 weeks. Results Iron depletion (ferritin <15 µg/l) was detected in 79 (23%) women in early pregnancy. Infant PWV (mean = 6.7 m/s, SD = 1.3, n = 284) was neither associated with maternal ferritin (adjusted change per 10 µg/l = 0.02, 95% CI: −0.01, 0.1), nor with iron depletion (adjusted change = −0.2, 95% CI: −0.6, 0.2). No evidence of association was observed between maternal serum transferrin receptor level and its ratio to ferritin with infant PWV. Maternal anaemia (<11 g/dl) at <20 weeks’ gestation was associated with a 1.0-m/s increase in infant PWV (adjusted 95% CI: 0.1, 1.9). Conclusion This is the largest study to date which has assessed peripheral PWV as a measure of arterial stiffness in infants. There was no evidence of an association between markers of maternal iron status early in pregnancy and infant PWV. PMID:25790854

  13. Baby on board: do responses to stress in the maternal brain mediate adverse pregnancy outcome?

    PubMed

    Douglas, Alison J

    2010-07-01

    Stress and adverse environmental surroundings result in suboptimal conditions in a pregnant mother such that she may experience poor pregnancy outcome including complete pregnancy failure and preterm labor. Furthermore her developing baby is at risk of adverse programming, which confers susceptibility to long term ill health. While some mechanisms at the feto-maternal interface underlying these conditions are understood, the underlying cause for their adverse adaptation is often not clear. Progesterone plays a key role at many levels, including control of neuroendocrine responses to stress, procuring the required immune balance and controlling placental and decidual function, and lack of progesterone can explain many of the unwanted consequences of stress. How stress that is perceived by the mother inhibits progesterone secretion and action is beginning to be investigated. This overview of maternal neuroendocrine responses to stress throughout pregnancy analyses how they interact to compromise progesterone secretion and precipitate undesirable effects in mother and offspring.

    1991-01-01

    The effects of maternal year of birth and age on the declining prevalence of neural tube defects after 1972-3 were examined using 403 cases ascertained in a prospective study in the Fylde of Lancashire during 1957-89. Matched case-control data were analysed using conditional logistic regression analysis. The risk of an anencephalic baby was significantly greater for older mothers, but changes in the maternal age distribution in the population did not appear to be relevant to the recent decline in prevalence. Antenatal diagnosis and termination of pregnancy was the major cause. Mothers born before 1950 were at significantly greater risk of producing a baby with spina bifida or cranium bifidum. We suggest that abandonment of mercury as a therapeutic agent for infants in the early 1950s is a possible factor in the current decline of these malformations. PMID:1953007

    We describe the first case of a baby with maternal uniparental disomy for chromosome 2. Growth failure, hypothyroidism and hyaline membrane disease were present at birth, and the first year of life was complicated by bronchopulmonary dysplasia. At 14 months, motor and intellectual development appear to be normal, but growth remains below the 10th percentile. The baby was investigated for uniparental disomy because trisomy 2 mosaicism had been detected in a second trimester amniocentesis. This is the first reported case in which amniotic fluid chromosome mosaicism has been associated with uniparental disomy. Implications for prenatal diagnosis are considered.

    BACKGROUND Birth defects affect 3% of babies born, and are one of the leading causes of infant mortality. Both younger and older maternal age may pose increased risks for certain birth defects. This study assessed the relationship between maternal age at the estimated delivery date and the risk for birth defects. METHODS Data were obtained from the National Birth Defects Prevention Study, a population-based case-control study including mothers across 10 states. Maternal age was stratified into six categories: <20, 20 to 24, 25 to 29, 30 to 34, 35 to 39, and ≥40 years, and also analyzed as a continuous variable. Logistic regression models adjusted for maternal race/ethnicity, education, body mass index (BMI), folic acid use, smoking, gravidity, and parental age difference were used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS For maternal age <20 years, associations with total anomalous pulmonary venous return (aOR, 2.3; 95% CI, 1.3–4.0), amniotic band sequence (aOR, 2.4; 95% CI, 1.5–3.8), and gastroschisis (aOR, 6.1; 95% CI, 4.8–8.0) were observed. For the ≥40 year age group, associations with several cardiac defects, esophageal atresia (aOR, 2.9; 95% CI, 1.7–4.9), hypospadias (aOR, 2.0; 95% CI, 1.4–3.0), and craniosynostosis (aOR, 1.6; 95% CI, 1.1–2.4) were observed. Results using maternal age as a continuous variable were consistent with those that used categorized maternal age. CONCLUSION Elucidating risk factors specific to women at either extreme of maternal age may offer prevention opportunities. All women should be made aware of prevention opportunities, such as folic acid supplementation, to reduce the occurrence of birth defects. PMID:22821755

    PubMed

    Sauer, Mark V

    2015-05-01

    Advanced age is a risk factor for female infertility, pregnancy loss, fetal anomalies, stillbirth, and obstetric complications. These concerns are based on centuries-old observations, yet women are delaying childbearing to pursue educational and career goals in greater numbers than ever before. As a result, reproductive medicine specialists are treating more patients with age-related infertility and recurrent pregnancy loss, while obstetricians are faced with managing pregnancies often complicated by both age and comorbidities. The media portrayal of a youthful but older woman, able to schedule her reproductive needs and balance family and job, has fueled the myth that "you can have it all," rarely characterizing the perils inherent to advanced-age reproduction. Reproductive medicine specialists and obstetrician/gynecologists should promote more realistic views of the evidence-based realities of advanced maternal age pregnancy, including its high-risk nature and often compromised outcomes. Doctors should also actively educate both patients and the public that there is a real danger of childlessness if individuals choose to delay reproduction. PMID:25934599

    Nurse leaders used the Centers for Disease Control and Prevention's survey on Maternity Practices in Infant Nutrition and Care, as well as Baby-Friendly Hospital Initiative guidelines, to transform maternity care in a safety-net hospital with more than 3,500 births annually. Implementing evidence-based guidelines to support breastfeeding was essential for a vulnerable population characterized by minimal prenatal care and high rates of diabetes, hypertension, obesity, and poverty. Research showing the importance of breastfeeding in protecting against these factors guided extensive changes in our maternity care model. The nursing and medical teams changed long-held practices that separated women from their newborns and observed substantial improvements in breastfeeding initiation and exclusive breastfeeding rates at discharge.

    Background Maternal smoking during pregnancy has been consistently related to low birthweight. However, older mothers, who are already at risk of giving birth to low birthweight infants, might be even more susceptible to the effects of maternal smoking. Therefore, this study aimed to examine the modified association between maternal smoking and low birthweight by maternal age. Methods Data were obtained from a questionnaire survey of all mothers of children born between 2004 and 2010 in Okinawa, Japan who underwent medical check-ups at age 3 months. Variables assessed were maternal smoking during pregnancy, maternal age, gestational age, parity, birth year, and complications during pregnancy. Stratified analyses were performed using a logistic regression model. Results In total, 92641 participants provided complete information on all variables. Over the 7 years studied, the proportion of mothers smoking during pregnancy decreased from 10.6% to 5.0%, while the prevalence of low birthweight did not change remarkably (around 10%). Maternal smoking was significantly associated with low birthweight in all age groups. The strength of the association increased with maternal age, both in crude and adjusted models. Conclusions Consistent with previous studies conducted in Western countries, this study demonstrates that maternal age has a modifying effect on the association between maternal smoking and birthweight. This finding suggests that specific education and health care programs for older smoking mothers are important to improve their foetal growth. PMID:26795494

    Background: Parental traumatization has been associated with increased risk for the expression of psychopathology in offspring, and maternal posttraumatic stress disorder (PTSD) appears to increase the risk for the development of offspring PTSD. In this study, Holocaust-related maternal age of exposure and PTSD were evaluated for their association with offspring ambient cortisol and PTSD-associated symptom expression. Method: Ninety-five Holocaust offspring and Jewish comparison subjects received diagnostic and psychological evaluations, and 24 h urinary cortisol was assayed by RIA. Offspring completed the parental PTSD questionnaire to assess maternal PTSD status. Maternal Holocaust exposure was identified as having occurred in childhood, adolescence, or adulthood and examined in relation to offspring psychobiology. Results: Urinary cortisol levels did not differ for Holocaust offspring and comparison subjects but differed significantly in offspring based on maternal age of exposure and maternal PTSD status. Increased maternal age of exposure and maternal PTSD were each associated with lower urinary cortisol in offspring, but did not exhibit a significant interaction. In addition, offspring PTSD-associated symptom severity increased with maternal age at exposure and PTSD diagnosis. A regression analysis of correlates of offspring cortisol indicated that both maternal age of exposure and maternal PTSD were significant predictors of lower offspring urinary cortisol, whereas childhood adversity and offspring PTSD symptoms were not. Conclusion: Offspring low cortisol and PTSD-associated symptom expression are related to maternal age of exposure, with the greatest effects associated with increased age at exposure. These effects are relatively independent of the negative consequences of being raised by a trauma survivor. These observations highlight the importance of maternal age of exposure in determining a psychobiology in offspring that is consistent with increased

    While many studies have focused on the detrimental effects of advanced maternal age and harmful prenatal environments on progeny, little is known about the role of beneficial non-Mendelian maternal inheritance on aging. Here, we report the effects of maternal age and maternal caloric restriction (CR) on the life span and health span of offspring for a clonal culture of the monogonont rotifer Brachionus manjavacas. Mothers on regimens of chronic CR (CCR) or intermittent fasting (IF) had increased life span compared with mothers fed ad libitum (AL). With increasing maternal age, life span and fecundity of female offspring of AL-fed mothers decreased significantly and life span of male offspring was unchanged, whereas body size of both male and female offspring increased. Maternal CR partially rescued these effects, increasing the mean life span of AL-fed female offspring but not male offspring and increasing the fecundity of AL-fed female offspring compared with offspring of mothers of the same age. Both maternal CR regimens decreased male offspring body size, but only maternal IF decreased body size of female offspring, whereas maternal CCR caused a slight increase. Understanding the genetic and biochemical basis of these different maternal effects on aging may guide effective interventions to improve health span and life span. PMID:24661622

    Maternal age at first childbirth has increased in most developed countries in the past 20 years. The purpose of this study is to investigate effects of maternal age at delivery and parity on successful initiation of exclusive breastfeeding (EBF). This retrospective study investigated 1193 singleton dyads with vaginal-delivered at 37–42 gestational weeks during January and December in 2011 at one large “Baby-Friendly” certified hospital in Japan. A multivariate logistic regression model was used to evaluate individual and combined effects of maternal age and parity on successful initiation of EBF after adjusted for pre-pregnancy body mass index, gestational weight gain, pregnancy complications, mothers' underlying illness, smoking and alcohol drinking habits, gestational week at delivery, child's sex and nurturing support from grandparents. Success rates of EBF at one month after child delivery was 69.4% in primiparous aged ≥ 35 (group A: n = 284), 73.5% in multiparous aged ≥ 35 (group B: n = 268), 74.3% in primiparous aged < 35 (group C: n = 432), and 82.3% in multiparous aged < 35 (group D: n = 209). Older maternal age and primiparous became independently associated with EBF initiation. The combined effect for successful initiation of EBF was the lowest in group A referent to group D both at discharge and at one month (odds ratio (OR) 5.9, 95% confidence interval (CI): 3.0–11.9, and OR 2.2, 95% CI: 1.4–3.4, respectively). Primiparous mothers in late child-bearing aged 35 years or older are at the greatest risk of EBF initiation. PMID:26844198

    Objective: We measured cord blood and urine 8-iso-prostaglandin F2α (8-iso-PGF2α) levels in babies of different gestational ages to determine lipid peroxidation status. Methods: Babies at gestational ages of 28-43 weeks were divided into group A (28-32 weeks), group B (33-36 weeks), group C (37-41 weeks), and group D (42-43 weeks). 8-iso-PGF2α in umbilical cord blood (UCB) at birth and urine at 6 hours after birth was and tested by ELISA. Results: UCB and urine 8-iso-PGF2α levels in group C were 130.09 ± 31.73 pg/ml and 27.14 ± 6.73 pg/ml, respectively. UCB 8-iso-PGF2α levels in group A and B were 188.42 ± 59.34 pg/ml and 189.37 ± 68.46 pg/ml, and urine 8-iso-PGF2α were 32.14 ± 7.32 pg/ml and 30.46 ± 8.83 pg/ml, respectively. Blood and urine 8-iso-PGF2α levels in group D (post-term) were 252.01 ± 46.42 pg/ml and 44.00 ± 8.50 pg/ml. For all babies, UCB and urine iso-PGF2α levels were significantly correlated (r = 0.65, P < 0.01). Conclusions: We established blood and urine iso-PGF2α levels in normal full-term babies. Urine 8-iso-PGF2α levels may reflect the extent of lipid peroxidation in babies. In pre-term and post-term babies, there was evidence for increased lipid peroxidation. PMID:25664058

  14. 'Comfortable in my own skin': a new form of sexual freedom for ageing baby boomers.

    2014-12-01

    'Freedom of sexual expression' is a slogan that has long been synonymous with the generation known as the baby boomers during the 1960s and 1970s. But does this catchphrase still have currency for the men and women in this cohort who are mostly now over the age of fifty? This paper explores the question by reporting on qualitative data from a multi-method Australian study about the influence of growing older on baby boomers' sexual expression. The sample comprised ten interview participants and fifty-seven Internet survey respondents, aged between 50 and 70 years. Following a theoretical perspective known as the sociology of emotions, the analysis of data reveals that baby boomers' emotional experiences range from constraining to liberating sexual expression, to a paradoxical combination of both. The article argues that while sexual freedom is still an important concept to baby boomers, there are new emotional dimensions to its expression, particularly in the form of comfort and confidence, that come with age.

    A range of early circumstances surrounding the birth of a child affects peripartum hormones, parental behavior and infant wellbeing. One of these factors, which may lead to postpartum depression, is the mode of delivery: vaginal delivery (VD) or cesarean section delivery (CSD). To test the hypothesis that CSD mothers would be less responsive to own baby-cry stimuli than VD mothers in the immediate postpartum period, we conducted functional magnetic resonance imaging, 2–4 weeks after delivery, of the brains of six mothers who delivered vaginally and six who had an elective CSD. VD mothers’ brains were significantly more responsive than CSD mothers’ brains to their own baby-cry in the superior and middle temporal gyri, superior frontal gyrus, medial fusiform gyrus, superior parietal lobe, as well as regions of the caudate, thalamus, hypothalamus, amygdala and pons. Also, within preferentially active regions of VD brains, there were correlations across all 12 mothers with out-of-magnet variables. These include correlations between own baby-cry responses in the left and right lenticular nuclei and parental preoccupations (r = .64, p < .05 and .67, p < .05 respectively), as well as in the superior frontal cortex and Beck depression inventory (r = .78, p < .01). First this suggests that VD mothers are more sensitive to own baby-cry than CSD mothers in the early postpartum in sensory processing, empathy, arousal, motivation, reward and habit-regulation circuits. Second, independent of mode of delivery, parental worries and mood are related to specific brain activations in response to own baby-cry. PMID:18771508

    Health of the children's population is one of the most important components of safety of the country. The incidence level in children of early age reflects an interaction of economic, ecological, social and hygienic and medico-organizational factors in society. The issue of the paper is the comprehensive assessment of health of children of the first three years of life upon indices of the morbidity rate, physical development, interrelation of given indices with the structure of the family and their social status. Indices of the physical development of boys in the all age groups exceeded the corresponding indices in girls (p < 0.05). There was also statistically significant and augmentation of indices of body weights of children along with the age (p < 0.05). The highest morbidity rate in children was established in the first year of life, the minimal one--in the third year. In the all age groups diseases of respiratory organs prevailed, at this their proportion in the total amount of diseases in the third year of life considerably exceeded the same in first and second years of life. The highest incidences of children took place in the families formed by juvenile and lonely women. Diseases of digestive organs in the second and third years of life in children from juvenile and lonely mothers were considerably enlarged on frequency (by 1,4-1,7 times), infectious and parasitic diseases (by 1,1-1,7 times) in comparison with children from full families. In the all studied types offamilies and age groups the state of health of children was worse, than in full families. There was substantiated the development of the multilevel system for the prophylaxis of losses of health in children at early preschool age. PMID:26856178

    Since more and more women in developed countries are delaying childbearing to an older age, it is important to find out whether birth defects, other than those resulting from chromosomal anomalies, are related to maternal age. We have studied all 26,859 children with birth defects of unknown aetiology identified among 576,815 consecutive livebirths in British Columbia. All these cases' records were linked with provincial birth records to allow determination of maternal age at birth. We excluded children with chromosomal anomalies and those with other birth defects of known aetiology. Only 3 of the 43 birth defect categories studied showed significant maternal-age-specific trends: there were decreasing linear trends with maternal age for patent ductus arteriosus (chi 2 = 36.65, 1 df, p less than 0.01) and hypertrophic pyloric stenosis (chi 2 = 4.90, 1 df, p less than 0.05) and a bell-shaped curve (risk increasing to maternal age 30 then falling) for congenital dislocatable hip/hip click. The findings from this population-based analysis of no association between the incidence of birth defects of unknown aetiology and advancing maternal age should be reassuring to healthy women who opt to delay childbearing.

    Summary Background National estimates for the numbers of babies born small for gestational age and the comorbidity with preterm birth are unavailable. We aimed to estimate the prevalence of term and preterm babies born small for gestational age (term-SGA and preterm-SGA), and the relation to low birthweight (<2500 g), in 138 countries of low and middle income in 2010. Methods Small for gestational age was defined as lower than the 10th centile for fetal growth from the 1991 US national reference population. Data from 22 birth cohort studies (14 low-income and middle-income countries) and from the WHO Global Survey on Maternal and Perinatal Health (23 countries) were used to model the prevalence of term-SGA births. Prevalence of preterm-SGA infants was calculated from meta-analyses. Findings In 2010, an estimated 32·4 million infants were born small for gestational age in low-income and middle-income countries (27% of livebirths), of whom 10·6 million infants were born at term and low birthweight. The prevalence of term-SGA babies ranged from 5·3% of livebirths in east Asia to 41·5% in south Asia, and the prevalence of preterm-SGA infants ranged from 1·2% in north Africa to 3·0% in southeast Asia. Of 18 million low-birthweight babies, 59% were term-SGA and 41% were preterm. Two-thirds of small-for-gestational-age infants were born in Asia (17·4 million in south Asia). Preterm-SGA babies totalled 2·8 million births in low-income and middle-income countries. Most small-for-gestational-age infants were born in India, Pakistan, Nigeria, and Bangladesh. Interpretation The burden of small-for-gestational-age births is very high in countries of low and middle income and is concentrated in south Asia. Implementation of effective interventions for babies born too small or too soon is an urgent priority to increase survival and reduce disability, stunting, and non-communicable diseases.

    Vitamin D deficiency is common during pregnancy and higher in Hispanic as compared with non-Hispanic white women. However, the association between vitamin D deficiency and adverse pregnancy outcomes remains unclear and may vary across ethnic groups, in part because of genetic variation in the metabolism of vitamin D. Few studies have included Hispanic women. Therefore, we investigated this association among 237 participants in the Behaviors Affecting Baby and You Study, a randomised trial of an exercise intervention among ethnically diverse prenatal care patients in Massachusetts. Baseline serum 25-hydroxyvitamin D (25(OH)D) was measured at 15·2 (sd 4·7) weeks' gestation. Information on adverse pregnancy outcomes was abstracted from medical records. Mean 25(OH)D was 30·4 (sd 12·0) ng/ml; 53·2 % of participants had insufficient (<30 ng/ml) and 20·7 % had deficient (<20 ng/ml) 25(OH)D levels. After adjusting for month of blood draw, gestational age at blood draw, gestational age at delivery, age, BMI and Hispanic ethnicity, women with insufficient and deficient vitamin D had infants with birth weights 139·74 (se 69·16) g (P=0·045) and 175·52 (se 89·45) g (P=0·051) lower compared with women with sufficient vitamin D levels (≥30 ng/ml). Each 1 ng/ml increase in 25(OH)D was associated with an increased risk for gestational diabetes mellitus among Hispanic women only (relative risk 1·07; 95 % CI 1·03, 1·11) in multivariable analysis. We did not observe statistically significant associations between maternal vitamin D status and other pregnancy outcomes. Our findings provide further support for an adverse impact of vitamin D deficiency on birth weight in Hispanic women. PMID:26507186

    There is controversy as to whether maternal age exerts an influence on the contractility of human myometrium in pregnancy. The aim of this study was to examine a series of functional contractile parameters of human myometrium in vitro, over a broad range of maternal ages. Myometrial tissue specimens were obtained at cesarean delivery from 32 women with maternal ages ranging from 28 to 52 years. Using in vitro recordings, a number of contractile parameters including maximal amplitude, mean contractile force, time to maximal amplitude, maximum rate of rise, and occurrence of simple and complex (biphasic and multiphasic) contractions were examined for spontaneous and induced contractile activity. The relationship between maternal age and individual parameters was evaluated using linear regression analysis. For all contractile parameters examined, for both spontaneous and induced contractions, no significant correlation was observed with maternal age between 28 and 52 years. The mean maximum amplitude values for spontaneous and oxytocin-induced contractions were 23 ± 3 and 43 ± 5 mN, respectively. The mean contractile forces for spontaneous and oxytocin-induced contractions were 1.5 ± 0.2 and 6.5 ± 0.9 mN, respectively. There was no variation in the proportion of biphasic or multiphasic contractions with maternal age. These results indicate there is no significant functional impairment of uterine contractility and no lack in responsiveness of myometrium in vitro, in the older mother. These findings do not support the concept that there may be a biological basis for dysfunctional labor or increased cesarean delivery rates in older parturients. PMID:25759369

    ABSTRACT Objective: Coeliac disease is a chronic disease and is common all over the world. It has many other associated systemic side effects. This study investigated the effect of paternal and maternal silent coeliac disease on birthweight and gestational age in newborns. Methods: The study group consisted of 81 newborns who were hospitalized for prematurity or term-intrauterine growth retardation. The parents of premature and/or small for gestational age babies born with coeliac disease-specific antigens were investigated. Results: The differences were not statistically significant in fathers' tissue transglutaminase levels between premature appropriate gestational age, premature small gestational age and term small gestational age infants (p > 0.05), but statistically significant in mothers (p < 0.05). Conclusions: Silent coeliac disease may occur in parents, especially in mothers of preterm and small for gestational age infants, even in the absence of apparent clinical indications. PMID:25781285

    Background Studies have shown that educating mothers can improve their adaptation to pregnancy and motherhood roles. There are also studies that have investigated the effects of certain interventions on maternal-fetal attachment. However, studies on the effects of maternal adaptation training on maternal-fetal attachment in mothers with a history of fetal or baby loss are rare. Objectives The aim of this study was to determine the effects of a pregnancy adaptation training package on maternal-fetal attachment in pregnant women with a history of baby loss. Patients and Methods This quasi-experimental study was conducted on 60 pregnant women with previous fetal or neonatal death in 2014. The women were randomly divided into an experimental group (n = 30) and a control group (n = 30). The pregnant women in the experimental group received routine prenatal education in addition to four sessions of a pregnancy adaption training package. The control group received only routine prenatal education. The data were collected using a demographic questionnaire, Cranley’s maternal-fetal attachment scale, and a prenatal self-evaluation questionnaire at the beginning and at the end of the study. The data analysis was conducted using the Mann-Whitney U, Wilcoxon, chi-square, Fisher’s exact, and spearman correlation coefficient tests. Results Before the intervention, there were no statistically significant differences between the study and control groups in terms of maternal-fetal attachment (P = 0.280) and adaptation to pregnancy (P = 0.883). However, following the intervention, the mean score of the maternal-fetal attachment was significantly higher in the experimental group, when compared with the control (77.57 ± 7.23 vs. 61.53 ± 2.62; P = 0.001). In addition, the mean post-intervention adaptation to pregnancy score was significantly lower in the experimental group than in the control group (118.89 ± 8.12 vs. 126.38 ± 4.17; P = 0.001). Conclusions The pregnancy adaptation

    Several studies have reported that the number of crossovers increases with maternal age in humans, but others have found the opposite. Resolving the true effect has implications for understanding the maternal age effect on aneuploidies. Here, we revisit this question in the largest sample to date using single nucleotide polymorphism (SNP)-chip data, comprising over 6,000 meioses from nine cohorts. We develop and fit a hierarchical model to allow for differences between cohorts and between mothers. We estimate that over 10 years, the expected number of maternal crossovers increases by 2.1% (95% credible interval (0.98%, 3.3%)). Our results are not consistent with the larger positive and negative effects previously reported in smaller cohorts. We see heterogeneity between cohorts that is likely due to chance effects in smaller samples, or possibly to confounders, emphasizing that care should be taken when interpreting results from any specific cohort about the effect of maternal age on recombination.

    The aims of the present study were to assess (1) the parental origin of trisomy 21 and the stage in which nondisjunction occurs and (2) the relationship between altered genetic recombination and maternal age as risk factors for trisomy 21. The study included 102 cases with Down syndrome from the Croatian population. Genotyping analyses were performed by polymerase chain reaction using 11 short tandem repeat markers along chromosome 21q. The vast majority of trisomy 21 was of maternal origin (93%), followed by paternal (5%) and mitotic origin (2%). The frequencies of maternal meiotic I (MI) and meiotic II errors were 86% and 14%, respectively. The highest proportion of cases with zero recombination was observed among those with maternal MI derived trisomy 21. A higher proportion of telomeric exchanges were presented in cases with maternal MI errors and cases with young mothers, although these findings were not statistically significant. The present study is the first report examining parental origin and altered genetic recombination as a risk factor for trisomy 21 in a Croatian population. The results support that trisomy 21 has a universal genetic etiology across different human populations. PMID:21861707

    Objective We utilized an updated nationally representative database to examine associations between maternal age and prevalence of maternal morbidity during complications of labor and delivery. Study design We used hospital inpatient billing data from the 2009 United States Nationwide Inpatient Sample (NIS), part of the Healthcare Cost and Utilization Project (HCUP). To determine whether the likelihood that maternal morbidity during complications of labor and delivery differed among age groups, separate logistic regression models were run for each complication. Age was the main independent variable of interest. Results In analyses that controlled for demographics and clinical confounders, we found that complications with the highest odds among women, 11–18 years of age, compared to 25–29 year old women, included preterm delivery, chorioamnionitis, endometritis, and mild preeclampsia. Pregnant women who were 15–19 years old had greater odds for severe preeclampsia, eclampsia, postpartum hemorrhage, poor fetal growth, and fetal distress. Pregnant women who were ≥35 years old had greater odds for preterm delivery, hypertension, superimposed preeclampsia, severe preeclampsia, and decreased risk for chorioamnionitis. Older women (≥40 years old) had increased odds for mild preeclampsia, fetal distress, and poor fetal growth. Conclusions Our findings underscore the need for pregnant women to be aware of the risks associated with extremes of age so that they can watch for signs and symptoms of such complications.

    Background Fetal sex and maternal age are each known to affect outcomes of pregnancies. The objective of the present study was to investigate the influence of the combination of maternal age and fetal sex on pregnancy outcomes in term and post-term singleton pregnancies. Material/Methods This was a retrospective study on term singleton pregnancies delivered between 2004 and 2008 at the Chaim Sheba Medical Center. Data collected included maternal age, fetal sex, and maternal and neonatal complications. The combined effect of fetal sex and maternal age on complications of pregnancy was assessed by multivariable logistic regression models. Results The study population comprised 37,327 pregnancies. The risk of operative deliveries increased with maternal age ≥40 and in pregnancies with male fetuses. The risk of maternal diabetes and of longer hospitalization increased as maternal age increased, and in women <40 carrying male fetuses. The risk of hypertensive disorders increased in pregnancies with males as maternal age advanced. The risk of shoulder dystocia and neonatal respiratory complications increased in male neonates born to women<40. The risk of neonatal hypoglycemia increased in males for all maternal ages.

Knowledge of fetal sex adds value to the risk assessment of pregnancies as maternal age increases. PMID:25892459

  12. Can we define maternal age as a genetic disease?

    PubMed Central

    Wilding, M.

    >Maternal age is strongly associated with a decrease in the probability of achieving pregnancy and the birth of a healthy child. Among current theories of the mechanism of this decrease is the hypothesis that a progressive degeneration of the respiratory capacity of mitochondria in eggs of women of advanced age leads to an energy deficit and consequent secondary effects on the oocyte and developing embryo. Mitochondria are uniquely inherited through the female germ line and these organelles contain DNA sequences that are independent from the genome. It is therefore possible that offspring born to females of advanced age inherit suboptimal mitochondria and that these persist throughout the life of the new being. This could in turn lead to long-term consequences for the offspring of females of advanced age such as a reduced potential lifespan in relation to the age of the mother at conception. In this review and hypothesis, we discuss the evidence relating to this theory and suggest that on this basis the maternal age effect could be classified as an inheritable genetic disease.

    It has long been recognised that mature-aged sibling dyads provide each other with emotional support. What has yet to be determined is whether this support function is maintained within the baby boomer generational cohort of sibling dyads who through economic relocation/migration have become separated by distance. As such, this paper highlights…

    The role of reproductive factors, such as parental age, in the pathogenesis of childhood leukemias is being intensively examined; the results of individual studies are controversial. This meta-analysis aims to quantitatively synthesize the published data on the association between parental age and risk of two major distinct childhood leukemia types in the offspring. Eligible studies were identified and pooled relative risk (RR) estimates were calculated using random-effects models, separately for childhood acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). Subgroup analyses were performed by study design, geographical region, adjustment factors; sensitivity analyses and meta-regression analyses were also undertaken. 77 studies (69 case-control and eight cohort) were deemed eligible. Older maternal and paternal age were associated with increased risk for childhood ALL (pooled RR = 1.05, 95 % CI 1.01-1.10; pooled RR = 1.04, 95 % CI 1.00-1.08, per 5 year increments, respectively). The association between maternal age and risk of childhood AML showed a U-shaped pattern, with symmetrically associated increased risk in the oldest (pooled RR = 1.23, 95 % CI 1.06-1.43) and the youngest (pooled RR = 1.23, 95 % CI 1.07-1.40) extremes. Lastly, only younger fathers were at increased risk of having a child with AML (pooled RR = 1.28, 95 % CI 1.04-1.59). In conclusion, maternal and paternal age represents a meaningful risk factor for childhood leukemia, albeit of different effect size by leukemia subtype. Genetic and socio-economic factors may underlie the observed associations. Well-adjusted studies, scheduled by large consortia, are anticipated to satisfactorily address methodological issues, whereas the potential underlying genetic mechanisms should be elucidated by basic research studies.

    Few information is available on parameters that can be used to objectively assess the foetal health during canine pregnancy. To identify a reliable parameter for the evaluation of foetal well-being, the effect of pre-gestational maternal bodyweight and gestational age on foetal heart rate (FHR) and on feto-maternal heart rate ratio (FHR/MHR) was investigated. Seventeen client-owned pregnant bitches of different pre-gestational maternal bodyweight were examined by serial echo colour Doppler. Only data from 11 uncomplicated pregnancies were included in the statistical analysis. The relationship between FHR, and FHR/MHR, and independent variables was analysed by polynomial regression (p ≤ .05). The FHR and the FHR/MHR significantly fitted a multiple quadratic regression for all independent variables. They both increased from 35 to 20 days before parturition and then a decreasing pattern followed. Higher values of both parameters were observed in bitches of lowest and highest bodyweight. Patterns of FHR and FHR/MHR were similar, but the ratio better describes the effect of the independent variables on the data. Thus, the highest significance of FHR/MHR compared to FHR alone encourages the application of this ratio to evaluate foetal well-being. The equation derived by the regression analysis of FHR/MHR could be applied in clinical practice to obtain its expected values in healthy pregnancies. PMID:27440379

    Intellectual functioning, parental age, and sexual orientation in 991 male sexual offenders were investigated. Sources of data included semistructured interviews, clinical charts, phallometric tests, and self-administered questionnaires. The results suggest two main conclusions: (i) Among pedophiles in general, erotic preference moves away from adult women along two dimensions: age and sex. The extent of this movement is greater, along both dimensions, for pedophiles with lower levels of intellectual functioning. (ii) High maternal age (or some factor it represents) increases the likelihood of exclusive sexual interest in boys. Intellectual deficiency (or some factor it represents) decreases the likelihood of exclusive sexual interest in girls. These two factors summate, so that a pedophile with both factors is more likely to be sexually interested in boys than a pedophile with only one. PMID:10483505

    The American Academy of Pediatrics recommends that infants be breastfed exclusively for the first 6 months of life, and that mothers continue breastfeeding for at least 1 year. However, in 2011, only 19.3% of mothers aged ≤20 years in the United States exclusively breastfed their infants at 3 months, compared with 36.4% of women aged 20-29 years and 45.0% of women aged ≥30 years. Hospitals play an essential role in providing care that helps mothers establish and continue breastfeeding. The U.S. Surgeon General and numerous health professional organizations recommend providing care aligned with the Baby-Friendly Hospital Initiative (BFHI), including adherence to the Ten Steps to Successful Breastfeeding (Ten Steps), as well as not providing gift packs containing infant formula. Implementing BFHI-aligned maternity care improves duration of any and exclusive breastfeeding among mothers; however, studies have not examined associations between BFHI-aligned maternity care and breastfeeding outcomes solely among adolescent mothers (for this report, adolescents refers to persons aged 12-19 years). Therefore, CDC analyzed 2009-2011 Pregnancy Risk Assessment Monitoring System (PRAMS) data and determined that among adolescent mothers who initiated breastfeeding, self-reported prevalence of experiencing any of the nine selected BFHI-aligned maternity care practices included in the PRAMS survey ranged from 29.2% to 95.4%. Among the five practices identified to be significantly associated with breastfeeding outcomes in this study, the more practices a mother experienced, the more likely she was to be breastfeeding (any amount or exclusively) at 4 weeks and 8 weeks postpartum. Given the substantial health advantages conferred to mothers and children through breastfeeding, and the particular vulnerability of adolescent mothers to lower breastfeeding rates, it is important for hospitals to provide evidence-based maternity practices related to breastfeeding as part of their

    Objectives To compare mental health and well-being outcomes at 3 and 9 months after the stillbirth among women who held or did not hold their baby, adjusting for demographic and clinical differences. Design Secondary analyses of data from a postal population survey. Population Women with a registered stillbirth in England in 2012. Methods 468 eligible responses were compared. Differences in demographic, clinical and care characteristics between those who held or did not hold their infant were described and adjusted for in subsequent analysis. Mental health and well-being outcomes were compared, and subgroup comparisons tested hypothesised moderating factors. Outcome Measures Self-reported depression, anxiety, post-traumatic stress disorder (PTSD) symptoms and relationship difficulties. Results There was a 30.2% response rate to the survey. Most women saw (97%, n=434) and held (84%, n=394) their baby after stillbirth. There were some demographic differences with migrant women, women who had a multiple birth and those whose pregnancy resulted from fertility treatment being less likely to hold their baby. Women who held their stillborn baby consistently reported higher rates of mental health and relationship difficulties. After adjustment, women who held their baby had 2.12 times higher odds (95% CI 1.11 to 4.04) of reporting anxiety at 9 months and 5.33 times higher odds (95% CI 1.26 to 22.53) of reporting relationship difficulties with family. Some evidence for proposed moderators was observed with poorer mental health reported by women who had held a stillborn baby of <33 weeks’ gestation, and those pregnant at outcome assessment. Conclusions This study supports concern about the negative impact of holding the infant after stillbirth. Results are limited by the observational nature of the study, survey response rate and inability to adjust for women's baseline anxiety. Findings add important evidence to a mixed body of literature.

    This study examined the relationships of age to use of alcohol, marijuana, and illicit drugs, and misuse of prescription drugs, among midlife women and whether these relationships are modified by birth cohort. Structural Equation Modeling was used to analyze National Survey on Drug Use and Health data, which included 2,035 baby boomer and silent generation cohort women, ages 30 to 55. Midlife women across cohorts reduced alcohol and marijuana use, but not illicit and prescription drug misuse, as they aged. A modifying effect of birth cohort was not supported, but findings did support differential aging effects across substances. Implications are discussed. PMID:26901493

    Current health care system serving 78M aging baby-boomers is no longer sustainable, as the cost about 1/5 GDP will reach 1/4 GDT when all is retired in decades, unless the system is changed. We design a high-tech safe net to enhance the timeliness of early correct treatment execution (otherwise, causing 1/4 mortality associated with an escalating legal fee waste). We follow the common sense that "a stitch in time saves nine," and adopt the military surveillance know-how in designing early warning health management system, comprising of smart sensor pairs for point-care surveillance. However, the grand plan of affordable smart sensors hardware for households requires an ODM & OEM teaming to conduct parallel designing and sequential marketing strategy. The military software strategy combating a treacherous adversary enemy match well with point cares surveillance overcoming real world microorganism variability. Moreover, such smart military software provides self-reference change detection, not by traditional cohort ensemble average, but by individual own higher order statistics (HOS) independent component analysis (ICA), which take the advantage of known initial condition for each individual and desirable over-sampling daily dynamics. The triggering of warning follows the military algorithms comprising of Receiver Operation Characteristics (ROC) and Automatic Target Recognition (ATR). To further reduce the unwanted false negative rate, a benchmarked is made against the traditional cohort-ensemble baseline average & the upper & lower bounds of variance as adopted by the gatekeepers - Medical Doctors (MD) and Nurses.

    Chaplains serving in the health care context provide a ministry to dying patients of inestimable worth as they comfort patients in the last chapter of the journey by being present, listening, and caring. Chaplains also play another important role, helping patients clarify ways in which their beliefs and values might influence health care decisions. This paper reviewed the current trends of spiritual diversity alongside the aging of a large Baby Boomer cohort. Chaplains may be challenged as they participate in the decision-making process, or as they support familes who make decisions about the care of loved ones nearing the end of life. Many of those who seek health care and comfort as the end of life approaches will bring a startling diversity of nonbelief, beliefs, and diverse religious and spiritual practices. This pattern of diversity will profoundly affect patients' decision-making around end-of-life issues. Case studies are used to illustrate possibilities for the chaplain's role at the bedside in the face of such diversity. The dimensional information of a new scale is presented for chaplains to assess diverse afterlife beliefs. As chaplains renew their studies of the worlds living religions, they will be better equipped to serve the needs of this large and spiritually diverse population. PMID:20183111

    BACKGROUND Brazil has witnessed dramatic changes in its fertility patterns in recent decades. The decline to below-replacement fertility has been accompanied by increases in the proportion of children born to young mothers. Yet we know little about the well-being of children born to young mothers in Brazil. OBJECTIVE and METHODS Using data from the 2006 Pesquisa Nacional de Demografia e Saúde and a quasi-natural experimental approach, this study examines the implications of maternal age at first birth for the education of Brazilian adolescents. RESULTS We find that being born to a young mother is associated with educational disadvantages in adolescence, but that these disadvantages are attenuated once we account for mothers’ selection into early childbearing. We also find that, in southern Brazil, adolescents born to young mothers have poorer educational outcomes compared with their peers born to older mothers, but that in northern Brazil no such disparities exist. CONCLUSIONS Adolescent educational disadvantages associated with being born to a young mother are not an artifact of selectivity, at least in southern Brazil. Regional variation in the effect of maternal age at first birth on adolescent education suggests the important role of the extended family and the father’s presence as mechanisms through which disadvantages operate.

    To investigate the possible risk factors related to macrosomia. Pregnant women and their newborns (n = 1041) were recruited from a cohort study in Maternal and Child Care Center of Hefei from January 2011 to July 2012. Questionnaires were applied to collect the demographic data besides the medical records. Detailed health records of the entire pregnancy were obtained using retrospective study. Meanwhile the data of neonatal outcomes was prospectively tracked. Associations between exposure risk factors and macrosomia were analyzed using Pearson's chi squared test. Logistic regression models were used to assess the independent association between these potential predictors and macrosomia. The incidence of macrosomia of this cohort was 11.24% of which male: female = 2.55:1. Male incidence (8.07%) of macrosomia was higher than female (3.17%), p < 0.001. Body mass index (BMI) before pregnancy (pre-BMI), maternal height, parity were not independently associated with macrosomia; multiple logistic regression analysis indicated that macrosomia was mainly independently associated with weight gain in pregnancy (OR=1.14, 95% CI [1.10-1.19]), maternal age (OR = 1.09, 95% CI [1.03-1.15]) and gestational age (OR = 1.62, 95% CI [1.31-1.99]), respectively. Our findings indicate that weight gain in pregnancy, maternal age and gestational age should be considered as independent risk factors for macrosomia. PMID:25954731

    Background. This study was done to assess the maternal and sociodemographic factors associated with low birth weight (LBW) babies. Methods. An unmatched case control study was done involving 159 cases (mothers having LBW singleton babies) and 159 controls (mothers having normal birth weight singleton babies). Results. More than 50% of LBW babies were from the mothers with height ≤145 cm while only 9.43% of NBW babies were from the mothers with that height. Finally, after multivariate logistic regression analysis, maternal height, time of first antenatal care (ANC) visit, number of ANC visits, iron supplementation, calcium supplementation, maternal education, any illness during pregnancy, and hypertension were found as the significant predictors of LBW. However, maternal blood group AB, normal maternal Body Mass Index (BMI), mother's age of 30 or more years, and starting ANC visit earlier were found to be protective for LBW. Conclusion. Study findings suggest that selectively targeted interventions such as delay age at first pregnancy, improving maternal education and nutrition, and iron and calcium supplementation can prevent LBW in Nepal.

    Maternal effects are ubiquitous in nature and affect a wide range of offspring phenotypes. Recent research suggests that maternal effects also contribute to ageing, but the theoretical basis for these observations is poorly understood. Here we develop a simple model to derive expectations for (i) if maternal effects on ageing evolve; (ii) the strength of maternal effects on ageing relative to direct environmental effects; and (iii) the predicted relationships between environmental quality, maternal age and offspring lifespan. Our model is based on the disposable soma theory of ageing, and the key assumption is thus that mothers trade off their own somatic maintenance against investment in offspring. This trade-off affects the biological age of offspring at birth in terms of accumulated damage, as indicated by biomarkers such as oxidative stress or telomere length. We find that the optimal allocation between investment in maternal somatic investment and investment in offspring results in old mothers and mothers with low resource availability producing offspring with reduced life span. Furthermore, the effects are interactive, such that the strongest maternal age effects on offspring lifespan are found under low resource availability. These findings are broadly consistent with results from laboratory studies investigating the onset and rate of ageing and field studies examining maternal effects on ageing in the wild.

    Many marketers have called the baby-boom generation, i.e., those individuals born between 1946 and 1964, one of the most over-studied and over-defined groups of individuals that has ever hit the marketplace. While it sometimes seems as if the attitudes, lifestyles, and problems of this large generation should be known to all, accurate generalizations about the baby boom are difficult to make. It is a diverse collection of individuals whose needs continue to shape American society. The key challenge to marketers will be to recognize these differences among the generations and take advantage of the opportunities presented to them. PMID:10142134

    2012-04-01

    Regardless of HIV status, all gay male Baby Boomers are aging in a context strongly shaped by HIV/AIDS. For this subcohort within the Baby Boom generation, the disproportionately high volume of AIDS deaths among gay men aged 25-44 years at the epidemic's peak (1987-1996) created a cohort effect, decimating their social networks and shaping their personal and social lives during the epidemic, throughout their life course, and into later years. But despite these lasting effects on an entire cohort of gay men, relevant scholarship narrowly focuses on older HIV-positive gay men using clinical, psychological, and social network approaches. It thus makes inadequate use of the life course perspective, which, by attention to timing, agency, and interdependence, can uncover the myriad interlocking and longitudinal aspects of the epidemic that affect this group. This article argues for the application of this latter approach to research into the lasting impacts of HIV/AIDS on this cohort of gay men. We examine HIV/AIDS mortality within this cohort at the epidemic's height, these deaths' concentration in urban gay communities, and the growing and increasingly diverse population of HIV-positive gay men born in the Baby Boom Years. Our conclusion suggests that a fuller examination of the role of HIV/AIDS in the lives of gay male Baby Boomers, using a life course perspective, is critical to appreciating this generation's heterogeneity and to expanding knowledge of how later life is shaped by the intersection between historical events, personal biography, and social and community ties.

    2012-06-01

    Drawing on the evolutionary terminal investment hypothesis and Trivers' (1974) parent-offspring conflict theory, we advance and evaluate a mediational model specifying why and how maternal age, via mating effort and parental investment, affects mother-child conflict. Data from a longitudinal study of 757 families indicate that (a) older maternal age predicts lower mating effort during the child's first 5 years of life, and (b) thereby, higher maternal investment in middle childhood when the child is around 10 years old. (c) Higher maternal investment, in turn, forecasts less child-perceived mother-child conflict in adolescence (age 15). These results proved robust against theoretically relevant covariates (family resources, parity, maternal education, and maternal personality characteristics) and in the context of an autoregressive model. Study limitations are noted and results are discussed in terms of the unique contributions of an evolutionary perspective to the determinants-of-parenting literature. PMID:22468690

  19. Growth curve analyses of the relationship between early maternal age and children's mathematics and reading performance.

    PubMed

    Torres, D Diego

    2015-03-01

    Regarding the methods used to examine the early maternal age-child academic outcomes relationship, the extant literature has tended to examine change using statistical analyses that fail to appreciate that individuals vary in their rates of growth. Of the one study I have been able to find that employs a true growth model to estimate this relationship, the authors only controlled for characteristics of the maternal household after family formation; confounding background factors of mothers that might select them into early childbearing, a possible source of bias, were ignored. The authors' findings nonetheless suggested an inverse relationship between early maternal age, i.e., a first birth between the ages of 13 and 17, and Canadian adolescents' mean math performance at age 10. Early maternal age was not related to the linear slope of age. To elucidate whether the early maternal age-child academic outcomes association, treated in a growth context, is consistent with this finding, the present study built on it using US data and explored children's mathematics and reading trajectories from age 5 on. Its unique contribution is that it further explicitly controlled for maternal background factors and employed a three-level growth model with repeated measures of children nested within their mothers. Though the strength of the relationship varied between mean initial academic performance and mean academic growth, results confirmed that early maternal age was negatively related to children's mathematics and reading achievement, net of post-teen first birth child-specific and maternal household factors. Once maternal background factors were included, there was no statistically significant relationship between early maternal age and either children's mean initial mathematics and reading scores or their mean mathematics and reading growth.

    The purpose of this study is to investigate a) longitudinal patterns of maternal postpartum alcohol use as well as its variation by maternal age at child birth and b) within maternal age groups, the association between other maternal characteristics and alcohol use patterns for the purposes of informed prevention design. Study sample consists of 3397 mothers from the Fragile Families and Child Wellbeing Study representing medium and large US urban areas. Maternal drinking and binge drinking were measured at child age 1, 3, and 5 years. We conducted separate longitudinal latent class analysis within each of the three pre-determined maternal age groups (ages 20-25, n = 1717; ages 26-35, n = 1367; ages 36+, n = 313). Results revealed different class structures for maternal age groups. While two classes (NB [non-binge]-drinkers and LL [low-level]-drinkers) were identified for mothers in each age group, a third class (binge drinkers) was separately distinguished for the two older age groups. Whereas binge drinking rates appear to remain stable over the 5 years postdelivery for mothers who gave birth in their early twenties, mothers ages 26 and older increasingly engaged in binge drinking over time, surpassing the binge drinking behavior of younger mothers. Depression significantly increases the odds of being a NB-drinker for the 20-25 age group and that of being a binge drinker for the 36+ age group, whereas smoking during pregnancy is associated with subsequent binge drinking only for mothers ages 20-25. Findings highlight the importance of distinguishing risk factors by maternal age groups for drinking while parenting a young child, to inform the design of intervention strategies tailored to mothers of particular ages.

    The purpose of this study is to investigate a) longitudinal patterns of maternal postpartum alcohol use as well as its variation by maternal age at child birth; b) within maternal age groups, the association between other maternal characteristics and alcohol use patterns for the purposes of informed prevention design. Study sample consists of 3,397 mothers from the Fragile Families and Child Wellbeing Study representing medium and large U.S. urban areas. Maternal drinking and binge drinking were measured at child age one, three, and five years. We conducted separate longitudinal latent class analysis within each of the three pre-determined maternal age groups (ages 20–25: n=1,717; ages 26–35: n=1,367; ages 36+: n=313). Results revealed different class structures for maternal age groups. While two classes (NB [non-binge]-drinkers and LL [low-level]-drinkers) were identified for mothers in each age group, a third class (binge drinkers) was separately distinguished for the two older age groups. Whereas binge drinking rates appear to remain stable over the five years post-delivery for mothers who gave birth in their early twenties, mothers ages 26 and older increasingly engaged in binge drinking over time, surpassing the binge drinking behavior of younger mothers.

  2. Advanced maternal age and risk perception: A qualitative study

    2012-01-01

    Background Advanced maternal age (AMA) is associated with several adverse pregnancy outcomes, hence these pregnancies are considered to be “high risk.” A review of the empirical literature suggests that it is not clear how women of AMA evaluate their pregnancy risk. This study aimed to address this gap by exploring the risk perception of pregnant women of AMA. Methods A qualitative descriptive study was undertaken to obtain a rich and detailed source of explanatory data regarding perceived pregnancy risk of 15 women of AMA. The sample was recruited from a variety of settings in Winnipeg, Canada. In-depth interviews were conducted with nulliparous women aged 35 years or older, in their third trimester, and with singleton pregnancies. Interviews were recorded and transcribed verbatim, and content analysis was used to identify themes and categories. Results Four main themes emerged: definition of pregnancy risk, factors influencing risk perception, risk alleviation strategies, and risk communication with health professionals. Conclusions Several factors may influence women's perception of pregnancy risk including medical risk, psychological elements, characteristics of the risk, stage of pregnancy, and health care provider’s opinion. Understanding these influential factors may help health professionals who care for pregnant women of AMA to gain insight into their perspectives on pregnancy risk and improve the effectiveness of risk communication strategies with this group.

    A case-control study was made in Gunma Prefecture of 1,390 mothers of babies born weighing 2,500 grams or less and an equal number of mothers of 3,000-up to-4,000 gram babies matched by place and month of birth. A correlation was found between low-birth-weight babies and maternal age, stature, menstrual history and past history. The mother's occupation, educational career, smoking habits, amount of sleep each day, date of issue of the Mother's Handbook and the number of the periodical health examinations received can be listed as socio-medical factors. Bleeding and lower abdominal pain during pregnancy, anemia and toxemia of pregnancy are found as prenatal factors. Low-birth-weight babies are found to be correlated with multiple pregnancy, breech presentation, placenta previa and premature separation of the placenta, also. PMID:6747384

    There has never been a greater need for scientists trained in reproductive science. Most developed countries are witnessing unprecedented rates of recourse to assisted conception sitting cheek-by-jowl with high rates of induced abortion. This article addresses these two incongruous faces of reproductive healthcare. Every year at least 44 million abortions are performed worldwide, many under unsafe and insanitary conditions that carry a significant risk to the lives of women deprived of safe, effective methods for controlling their fertility. Although birth control is a complex issue involving myriad social and political factors, the technical vacuum in this area is significant. Through no fault of the family planning authorities, there have been no radically new methods of fertility control since the oral contraceptive pill was introduced in 1960 and even this contribution to planned parenthood has its roots in the biochemistry of the 1920s and 1930s. Moreover, the pharmaceutical industry has, by and large, turned its back on fundamental research activities in this area. At present, our major investment in reproductive healthcare involves treating ever-increasing numbers of couples with assisted reproductive technologies (ART). However, these treatments are often delivered without critically considering the underlying causes of this condition or seriously contemplating the long-term consequences of the current enthusiasm for such therapy. Significantly, the clinical factors underpinning the commitment of couples to ART include advanced maternal age and a variety of lifestyle factors, such as smoking and obesity, which are known to compromise the developmental potential of the oocyte and DNA integrity in spermatozoa.

    The article addresses debates around the changing nature of old age, using U.K. data on spending on dress and related aspects of appearance by older women to explore the potential role of consumption in the reconstitution of aged identities. Based on pseudo-cohort analysis of Family Expenditures Survey, it compares spending patterns on clothing, cosmetics and hairdressing, 1961-2011. It concludes that there is little evidence for the 'baby boomers' as a strategic or distinctive generation. There is evidence, however, for increased engagement by older women in aspects of appearance: shopping for clothes more frequently; more involved in the purchase of cosmetics; and women over 75 are now the most frequent attenders at hairdressers. The roots of these patterns, however, lie more in period than cohort effects, and in the role of producer-led developments such as mass cheap fashion and the development of anti-ageing products.

  8. Mapping for maternal and newborn health: the distributions of women of childbearing age, pregnancies and births

    PubMed Central

    2014-01-01

    Background The health and survival of women and their new-born babies in low income countries has been a key priority in public health since the 1990s. However, basic planning data, such as numbers of pregnancies and births, remain difficult to obtain and information is also lacking on geographic access to key services, such as facilities with skilled health workers. For maternal and newborn health and survival, planning for safer births and healthier newborns could be improved by more accurate estimations of the distributions of women of childbearing age. Moreover, subnational estimates of projected future numbers of pregnancies are needed for more effective strategies on human resources and infrastructure, while there is a need to link information on pregnancies to better information on health facilities in districts and regions so that coverage of services can be assessed. Methods This paper outlines demographic mapping methods based on freely available data for the production of high resolution datasets depicting estimates of numbers of people, women of childbearing age, live births and pregnancies, and distribution of comprehensive EmONC facilities in four large high burden countries: Afghanistan, Bangladesh, Ethiopia and Tanzania. Satellite derived maps of settlements and land cover were constructed and used to redistribute areal census counts to produce detailed maps of the distributions of women of childbearing age. Household survey data, UN statistics and other sources on growth rates, age specific fertility rates, live births, stillbirths and abortions were then integrated to convert the population distribution datasets to gridded estimates of births and pregnancies. Results and conclusions These estimates, which can be produced for current, past or future years based on standard demographic projections, can provide the basis for strategic intelligence, planning services, and provide denominators for subnational indicators to track progress.

    The impact of a baby book intervention on promoting positive reading beliefs and increasing reading frequency for low-income, new mothers (n = 167) was examined. The Baby Books Project randomly assigned low-income, first-time mothers to one of three study conditions, receiving educational books, non-educational books, or no books, during pregnancy and over the first year of parenthood. Home-based data collection occurred through pregnancy until 18 months post-partum. Mothers who received free baby books had higher beliefs about the importance of reading, the value of having resources to support reading, and the importance of verbal participation during reading. The results showed that providing any type of baby books to mothers positively influenced maternal reading beliefs, but did not increase infant-mother reading practices. Maternal reading beliefs across all three groups were significantly associated with self-reported reading frequency when children were at least 12 months of age. PMID:25264394

    OBJECTIVES: This study explored whether ethnic differences in the impact of advanced maternal age on the risk of Down syndrome might reflect differences in use of prenatal diagnostic technologies. METHODS: Maternal age-specific odds of Down syndrome and amniocentesis use were compared among African Americans, Mexican Americans, and non-Hispanic Whites via birth data for the years 1989 to 1991. RESULTS: The odds ratio and population attributable risk of Down syndrome due to maternal age of 35 years or older were highest for Mexican Americans, intermediate for African Americans, and lowest for non-Hispanic Whites. CONCLUSIONS: Advanced maternal age has a greater impact on the risk of Down syndrome for African American and, particularly, Mexican American women than for non-Hispanic White women. This difference in impact might reflect lower availability or use of prenatal diagnostic technologies. PMID:11076250

  14. How are older maternal age and grand multiparity related to infant health?

    PubMed

    Haaga, J G

    1989-12-01

    Most of the studies that have shown excess risks of morbidity and mortality for infants born to older mothers or those at very high parity have used data from countries with low infant mortality rates, mainly in Europe and North America. In these countries, increasing numbers of women are delaying childbearing into their thirties and early forties, making the consequences of older maternal age for the infant an important public health concern. Grand multiparity, by contrast, is now exceedingly rare in those countries. In many developing countries, however, childbearing typically continues, even if it does not start, at older maternal ages, and grand multiparity is not at all uncommon, It is thus important for the design and targeting of maternal and child health and family planning programs to distinguish the effects of infant health of high parity from those of older maternal age, and of maternal age as such from those of primiparity at older ages. This review uses data from countries that now have low fertility and infant mortality rates as well as from countries where both rates are higher to assess the evidence for different mechanisms through which maternal age and parity affect infant health.

    Family history (FH) of dementia is a major risk factor for Alzheimer's disease, particularly when the FH is maternal and when the age of dementia onset (AO) is younger. This study tested whether brain amyloid-beta deposition, measured in vivo with (11)C-Pittsburgh compound B (PiB), was associated with parental dementia and/or younger parental AO. Detailed FH and positron emission tomography (PiB) data were acquired in 147 nondemented aging individuals (mean age 75 ± 8). No participant had both positive maternal and paternal FH. A series of analyses revealed that those with maternal, but not paternal, FH had greater levels of PiB retention in a global cortical region than those without FH. PiB retention in maternal FH was not significantly greater than paternal FH. Younger maternal dementia AO was related to greater PiB retention in offspring, whereas younger paternal dementia AO was not. Overall, results suggest that not only is amyloid-beta burden greater in individuals with maternal FH, but also that the burden is greater in association with younger maternal AO. PMID:26973104

    The present study investigated maternal dispositional empathy and skin conductance level (SCL) reactivity to infant emotional cues as joint predictors of maternal sensitivity. Sixty-four mother-toddler dyads (31 boys) were observed across a series of interaction tasks during a laboratory visit, and maternal sensitivity was coded from approximately 55 minutes of observation per family. In a second, mother-only laboratory visit, maternal SCL reactivity to infant cues was assessed using a cry-laugh audio paradigm. Mothers reported on their dispositional empathy via a questionnaire. As hypothesized, mothers with greater dispositional empathy exhibited more sensitive behavior at low, but not high, levels of SCL reactivity to infant cues. Analyses examining self-reported emotional reactivity to the cry-laugh audio paradigm yielded a similar finding: dispositional empathy was related to greater sensitivity when mothers reported low, but not high, negative emotional reactivity. Results provide support for Dix’s (1991) affective model of parenting that underscores the combined contribution of the parent’s empathic tendencies and his/her own emotional experience in response to child emotions. Specificity of the Empathy × Reactivity interaction is discussed with respect to the context in which reactivity was assessed (infant cry versus laugh) and the type of sensitivity examined (sensitivity to the child’s distress versus non-distress).

  18. The evolutionary dynamics of timing of maternal immunity: evaluating the role of age-specific mortality.

    If a female survives an infection, she can transfer antibodies against that particular pathogen to any future offspring she produces. The resulting protection of offspring for a period after their birth is termed maternal immunity. Because infection in newborns is associated with high mortality, the duration of this protection is expected to be under strong selection. Evolutionary modelling structured around a trade-off between fertility and duration of maternal immunity has indicated selection for longer duration of maternal immunity for hosts with longer lifespans. Here, we use a new modelling framework to extend this analysis to consider characteristics of pathogens (and hosts) in further detail. Importantly, given the challenges in characterizing trade-offs linked to immune function empirically, our model makes no assumptions about costs of longer lasting maternal immunity. Rather, a key component of this analysis is variation in mortality over age. We found that the optimal duration of maternal immunity is shaped by the shifting balance of the burden of infection between young and old individuals. As age of infection depends on characteristics of both the host and the pathogen, both affect the evolution of duration of maternal immunity. Our analysis provides additional support for selection for longer duration of maternal immunity in long-lived hosts, even in the absence of explicit costs linked to duration of maternal immunity. Further, the scope of our results provides explanations for exceptions to the general correlation between duration of maternal immunity and lifespan, as we found that both pathogen characteristics and trans-generational effects can lead to important shifts in fitness linked to maternal immunity. Finally, our analysis points to new directions for quantifying the trade-offs that drive the development of the immune system. PMID:25611057

    Polymorphic DNA markers have recently been used to estimate the fraction of trisomy 21 (Down syndrome) cases that may be attributable to postzygotic nondisjunction - indicative of a loss in the fidelity of the first few cell divisions after fertilization. In these studies, a postzygotic nondisjunction is defined as a case in which two chromosomes of the trisomic set are homozygous for all informative markers (i.e., for those markers that were heterozygous in their parent of origin). These studies estimate that the postzygotic mutation mechanism accounts for 4.5% (11/238) and 3.5% (9/255) of their cases, respectively, but their estimates may actually be conservative, since all noninformative haplotypes (frequency not reported) are arbitrarily attributed to meiosis II-type nondisjunction. Nevertheless, even the conservative estimates would, if confirmed, constitute a new and nonnegligible source of chromosomal segregation errors leading to trisomy. These studies` conclusions are supported by the observation that the 20 reported {open_quotes}postzygotic{close_quotes} cases (5 paternal and 15 maternal) appear to be less dependent on maternal age (mean maternal age 28.4 years) than maternal meiosis I-type failures (mean maternal age 31.2 years). However, given the limited sample size involved, one should be cautious in positing the absence of a maternal age effect. 5 refs., 1 fig.

    Maternal deprivation of neonatal animals has been shown to induce long-lasting changes in the reactivity of the neuroendocrine system. The aim of the present study was to investigate whether maternal deprivation also affects susceptibility to immune-mediated diseases such as experimental autoimmune encephalomyelitis (EAE) in adult life. To this end, 9-day-old rat pups were subjected to a short-lasting maternal deprivation for a period of 24 h. At the age of 8 weeks, we induced EAE in these rats by immunization with myelin basic protein (MBP) in complete Freund's adjuvant. Our data demonstrate that short-lasting maternal deprivation induces a marked increase in the severity of EAE in the animals in later life. The histopathological evaluation of spinal cord and cerebellum corresponded with the observed differences in clinical symptoms of EAE. Moreover, neonatal maternal deprivation affects macrophage functioning at adult age. In contrast, no differences were observed in in vitro mitogen- and MBP-induced cytokine production by splenocytes. LPS-induced corticosterone release did not differ either between maternally deprived and control animals. We conclude that short-lasting neonatal maternal deprivation of rat pups has long-lasting consequences for macrophage activity and for susceptibility to the inflammatory autoimmune disease EAE.

    Purpose To investigate the association between maternal reproductive age and their children’ refractive error progression in Chinese urban students. Methods The Beijing Myopia Progression Study was a three-year cohort investigation. Cycloplegic refraction of these students at both baseline and follow-up vision examinations, as well as non-cycloplegic refraction of their parents at baseline, were performed. Student’s refractive change was defined as the cycloplegic spherical equivalent (SE) of the right eye at the final follow-up minus the cycloplegic SE of the right eye at baseline. Results At the final follow-up, 241 students (62.4%) were reexamined. 226 students (58.5%) with completed refractive data, as well as completed parental reproductive age data, were enrolled. The average paternal and maternal age increased from 29.4 years and 27.5 years in 1993–1994 to 32.6 years and 29.2 years in 2003–2004, respectively. In the multivariate analysis, students who were younger (β = 0.08 diopter/year/year, P<0.001), with more myopic refraction at baseline (β = 0.02 diopter/year/diopter, P = 0.01), and with older maternal reproductive age (β = -0.18 diopter/year/decade, P = 0.01), had more myopic refractive change. After stratifying the parental reproductive age into quartile groups, children with older maternal reproductive age (trend test: P = 0.04) had more myopic refractive change, after adjusting for the children's age, baseline refraction, maternal refraction, and near work time. However, no significant association between myopic refractive change and paternal reproductive age was found. Conclusions In this cohort, children with older maternal reproductive age had more myopic refractive change. This new risk factor for myopia progression may partially explain the faster myopic progression found in the Chinese population in recent decades. PMID:26421841

    The early-life environment, in particular maternal diet during pregnancy, influences a wide range of organs and systems in adult offspring. Mounting evidence suggests that developmental programming can also influence health and disease in grand-offspring. Transgenerational effects can be defined as those persisting into an F2 generation, where the F0 mother experiences suboptimal diet during her pregnancy. In this review, we critically examine evidence for transgenerational developmental programming effects in human populations, focusing on metabolic and reproductive outcomes. We discuss evidence from historical cohorts suggesting that grandchildren of women exposed to famine and other dietary alterations during pregnancy may experience increased rates of later health complications than their control counterparts. The methodological difficulties with transgenerational studies in human cohorts are explored. In particular, the problems with assessing reproductive outcomes in human populations are discussed. In light of the relative paucity of evidence available from human cohorts, we consider key insights from transgenerational experimental animal models of developmental programming by maternal diet; data are drawn from a range of rodent models, as well as the guinea-pig and the sheep. The evidence for different potential mechanisms of transgenerational inheritance or re-propagation of developmental programming effects is evaluated. Transgenerational effects could be transmitted through methylation of the gametes via the paternal and maternal lineage, as well as other possible mechanisms via the maternal lineage. Finally, future directions for exploring these underlying mechanisms further are proposed, including utilizing large, well-characterized, prospective pregnancy cohorts that include biobanks, which have been established in various populations during the last few decades.

    Nulliparous Long-Evans rats were bred at one of four different ages and assigned to one of three treatment groups within each age condition. Maternal ages were 9, 18, 32, and 36 weeks. Treatment groups were ethanol (E), administered by gavage as 8 g/kg in two divided doses on days 10-14 of gestation, pair-fed (PF) controls, administered as an isocaloric sucrose solution by gavage on days 10-14 of gestation, and ad lib fed controls (C). All offspring were surrogate fostered shortly after delivery to untreated recently parturient dams. Litter sizes were standardized to 8 on the day of birth. Offspring were assessed longitudinally for growth, mortality, and behavior (olfaction, locomotor activity, maze learning, avoidance acquisition and startle). Approximately 85% of the 36 week old dams did not produce viable litters. In the remaining maternal age conditions, ethanol delayed offspring olfactory orientation and increased locomotor activity, the latter dissipating after 50-60 days of age. These ethanol-related effects occurred independent of maternal age condition. Maternal age, independent of ethanol, was a factor which reduced litter size and offspring weight up to 50 days, but produced few effects on behavior. The combination of maternal age and prenatal ethanol interacted to increase pregnancy loss (oldest maternal age), reduce offspring weight up to day 99 (oldest and middle maternal age), alter olfactory orientation performance (oldest and middle maternal age), reverse the typical ethanol-induced increase in activity for males in the figure-8 test (oldest maternal age group), shift the pattern of open-field activity, and change errors in a complex water maze. Not all of these interactions turned out to be specific to the ethanol X old maternal age condition. Several of the interactions occurred in both the old and middle maternal age conditions. The only effect of old maternal age that interacted strongly with ethanol was in their combined effects on

  6. The Impact of Early Age at First Childbirth on Maternal and Infant Health

    2015-01-01

    The objective of this review was to assess whether early age at first childbirth is associated with increased risk of poor pregnancy outcomes. Early age at childbirth is variously defined in studies of its effect on maternal and infant health. In this systematic review, we limit analysis to studies of at least moderate quality that examine first births among young mothers, where young maternal age is defined as low gynaecological age (≤2 years since menarche) or as a chronological age ≤16 years at conception or delivery. We conduct meta-analyses for specific maternal or infant health outcomes when there are at least three moderate quality studies that define the exposure and outcome in a similar manner and provide odds ratios or risk ratios as their effect estimates. We conclude that the overall evidence of effect for very young maternal age (<15 years or <2 years post-menarche) on infant outcomes is moderate; that is, future studies are likely to refine the estimate of effect or precision but not to change the conclusion. Evidence points to an impact of young maternal age on low birthweight and preterm birth, which may mediate other infant outcomes such as neonatal mortality. The evidence that young maternal age increases risk for maternal anaemia is also fairly strong, although information on other nutritional outcomes and maternal morbidity/mortality is less clear. Many of the differences observed among older teenagers with respect to infant outcomes may be because of socio-economic or behavioural differences, although these may vary by country/ setting. Future, high quality observational studies in low income settings are recommended in order to address the question of generalisability of evidence. In particular, studies in low income countries need to consider low gynaecological age, rather than simply chronological age, as an exposure. As well, country-specific studies should measure the minimum age at which childbearing for teens has similar associations

    Background and purpose - Results from case-control studies of maternal age at conception and risk of idiopathic clubfoot have been inconsistent. We conducted a meta-analysis to determine whether there is any association between maternal age at conception and the morbidity of idiopathic clubfoot. Methods - We searched PubMed-MEDLINE, EMBASE, and the Cochrane Library up to June 2015 and supplemented the search with manual searches of the reference lists of the articles identified. 11 studies published between 1990 and 2015 were pooled. We investigated heterogeneity in maternal age and whether publication bias might have affected the results. Results - Compared to a control group, maternal age at conception of between 20 and 24 years old was associated with an increased risk of occurrence of clubfoot (OR = 1.2, 95% CI: 1.1-1.4). No such association was found for the age groups of ≥ 35, 30-34, 25-29, and < 20 years. There was no heterogeneity in the age groups of ≥ 35, 30-34, and 20-24 years, moderate heterogeneity in the 25- to 29-year age group, and a large degree of heterogeneity in the group that was < 20 years of age. The prediction intervals for the age groups of 25-29 and < 20 years were 0.56 to 1.3 and -0.39 to 2.4, respectively. We found no evidence of significant publication bias. Interpretation - From the results of this meta-analysis of 11 studies, maternal age at conception between 20 to 24 years of age appears to be associated with an increased risk of occurrence of clubfoot.

    Maternal age effect is well-known in the origin of numerical chromosomal aberrations and some isolated congenital abnormalities (CAs). The sex ratio (SR), i.e. number of males divided by the number of males and females together, of most CAs deviates from the SR of newborn population (0.51). The objective of this analysis was to evaluate the possible association of maternal age with the SR of isolated CAs in a population-based large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980-1996. First, SR of 24 CA entities/groups was estimated in 21,494 patients with isolated CA. In the next step SR of different maternal age groups was compared to the mean SR of the given CA-groups. The SR of four CA-groups showed some deviation in certain maternal age groups. Cases with anencephaly had female excess in young mothers (<25 years). Cases with skull's CAs particularly craniosynostosis had a male excess in cases born to women over 30 years. Two other CA groups (cleft lip ± palate and valvar pulmonic stenosis within the group of right-sided obstructive defect of heart) had significant deviation in SR of certain maternal age groups from the mean SR, but these deviations were not harmonized with joining age groups and thus were considered as a chance effect due to multiple testing. In conclusion, our study did not suggest that in general SR of isolated CAs might be modified by certain maternal age groups with some exception such as anencephaly and craniosynostosis.

    Uterine rupture is a potentially avoidable complication resulting in poor perinatal and maternal outcomes. This case had a number of unusual features including delivery of a healthy live baby; spontaneous posterior uterine rupture in a primigravida (and unscarred uterus); and delayed presentation with signs of peritonitis and sepsis rather than haemorrhage. A 19-year old primigravida had a vaginal delivery of a live infant at term, reporting having taken herbs to induce labour. She deteriorated and was transferred to our unit where she was found to have reduced consciousness, a distended abdomen and signs of sepsis. At laparotomy there was blood-stained ascites, signs of peritonitis and a posterior lower segment uterine rupture. A sub-total hysterectomy was performed but the patient's condition worsened resulting in maternal death 5 days post-operatively. This case highlights a number of differences in the presentation, management and outcomes of uterine rupture in resource-poor compared to resource-rich countries. PMID:27222683

    Objectives. In order to comprehensively examine the risks and resources associated with racial-ethnic disparities in adverse obstetric outcomes, the Los Angeles County Department of Public Health and the University of California, Los Angeles, joined efforts to design and implement the 2007 Los Angeles Mommy and Baby (LAMB) study. This paper aims to present the conceptual frameworks underlying the study's development, highlight the successful collaboration between a research institution and local health department, describe the distinguishing characteristics of its methodology, and discuss the study's implications for research, programs, and policies. Methods. The LAMB study utilized a multilevel, multistage cluster design with a mixed-mode methodology for data collection. Two samples were ultimately produced: the multilevel sample (n = 4,518) and the augmented final sample (n = 6,264). Results. The LAMB study allowed us to collect multilevel data on the risks and resources associated with racial-ethnic disparities in adverse obstetric outcomes. Both samples were more likely to be Hispanic, aged 20–34 years, completed at least 12 years of schooling, and spoke English. Conclusions. The LAMB study represents the successful collaboration between an academic institution and local health department and is a theoretically based research database and surveillance system that informs effective programmatic and policy interventions to improve outcomes among LAC's varied demographic groups.

    The evidence regarding older parental age and incidence of mood disorder symptoms in offspring is limited, and that which exists is mixed. We sought to clarify these relationships by using data from the Western Australian Pregnancy Cohort (Raine) Study. The Raine Study provided comprehensive data from 2,900 pregnancies, resulting in 2,868 live born children. A total of 1,220 participants completed the short form of the Depression Anxiety Stress Scale (DASS-21) at the 20-year cohort follow-up. We used negative binomial regression analyses with log link and with adjustment for known perinatal risk factors to examine the extent to which maternal and paternal age at childbirth predicted continuous DASS-21 index scores. In the final multivariate models, a maternal age of 30-34 years was associated with significant increases in stress DASS-21 scores in female offspring relative to female offspring of 25- to 29-year-old mothers. A maternal age of 35 years and over was associated with increased scores on all DASS-21 scales in female offspring. Our results indicate that older maternal age is associated with depression, anxiety, and stress symptoms in young adult females. Further research into the mechanisms underpinning this relationship is needed. PMID:26569038

    Meiotic recombination is a genetic process that is critical for proper chromosome segregation in many organisms. Despite being fundamental for organismal fitness, rates of crossing over vary greatly between taxa. Both genetic and environmental factors contribute to phenotypic variation in crossover frequency, as do genotype-environment interactions. Here, we test the hypothesis that maternal age influences rates of crossing over in a genotypic-specific manner. Using classical genetic techniques, we estimated rates of crossing over for individual Drosophila melanogaster females from five strains over their lifetime from a single mating event. We find that both age and genetic background significantly contribute to observed variation in recombination frequency, as do genotype-age interactions. We further find differences in the effect of age on recombination frequency in the two genomic regions surveyed. Our results highlight the complexity of recombination rate variation and reveal a new role of genotype by maternal age interactions in mediating recombination rate. PMID:26994290

    Maternal age at conception has long been demonstrated to have a significant correlation with pregnancy outcome and maternal health. Classically, very young (<20 years old) and old (= or >35 years) women have been classified as high-risk categories for child bearing. Recently, career, education, financial, and other goals have coerced women to delay childbearing all over the world. This trend is also becoming apparent in Pakistan, especially in the upper middle class, wealthy and educated women, as they become increasingly empowered. This review presents the association between maternal age and pregnancy outcome, particularly in the context of statistics of Pakistan, and its possible repercussions. On one hand, physicians need to develop effective counseling strategies for their patients in this regard, and on the other, more studies are required to ascertain the attitudes of Pakistani women, particularly those belonging to the upper and middle classes, regarding delayed childbearing, that can aid physicians in formulating effective counseling strategies.

  18. Efficacy of baby-CIMT: study protocol for a randomised controlled trial on infants below age 12 months, with clinical signs of unilateral CP

    PubMed Central

    2014-01-01

    Background Infants with unilateral brain lesions are at high risk of developing unilateral cerebral palsy (CP). Given the great plasticity of the young brain, possible interventions for infants at risk of unilateral CP deserve exploration. Constraint-induced movement therapy (CIMT) is known to be effective for older children with unilateral CP but is not systematically used for infants. The development of CIMT for infants (baby-CIMT) is described here, as is the methodology of an RCT comparing the effects on manual ability development of baby-CIMT versus baby-massage. The main hypothesis is that infants receiving baby-CIMT will develop manual ability in the involved hand faster than will infants receiving baby-massage in the first year of life. Method and design The study will be a randomised, controlled, prospective parallel-group trial. Invited infants will be to be randomised to either the baby-CIMT or the baby-massage group if they: 1) are at risk of developing unilateral CP due to a known neonatal event affecting the brain or 2) have been referred to Astrid Lindgren Children’s Hospital due to asymmetric hand function. The inclusion criteria are age 3–8 months and established asymmetric hand use. Infants in both groups will receive two 6-weeks training periods separated by a 6-week pause, for 12 weeks in total of treatment. The primary outcome measure will be the new Hand Assessment for Infants (HAI) for evaluating manual ability. In addition, the Parenting Sense of Competence scale and Alberta Infant Motor Scale will be used. Clinical neuroimaging will be utilized to characterise the brain lesion type. To compare outcomes between treatment groups generalised linear models will be used. Discussion The model of early intensive intervention for hand function, baby-CIMT evaluated by the Hand Assessment for Infants (HAI) will have the potential to significantly increase our understanding of how early intervention of upper limb function in infants at risk of

    Plagiocephaly was diagnosed in a baby aged 4 months and brachycephaly in a baby aged 5 months. Positional or deformational plagio- or brachycephaly is characterized by changes in shape and symmetry of the cranial vault. Treatment options are conservative and may include physiotherapy and helmet therapy. During the last two decades the incidence of positional plagiocephaly has increased in the Netherlands. This increase is due to the recommendation that babies be laid on their backs in order to reduce the risk of sudden infant death syndrome. We suggest the following: in cases of positional preference of the infant, referral to a physiotherapist is indicated. In cases of unacceptable deformity of the cranium at the age 5 months, moulding helmet therapy is a possible treatment option. PMID:19857299

    Parental child-feeding attitudes and practices may compromise the development of healthy eating habits and adequate weight status in children. This study aimed to identify maternal child-feeding patterns in preschool-aged children and to evaluate their association with maternal social and health behavioural characteristics. Trained interviewers evaluated 4724 dyads of mothers and their 4-5-year-old child from the Generation XXI cohort. Maternal child-feeding attitudes and practices were assessed through the Child Feeding Questionnaire and the Overt/Covert Control scale. Associations were estimated using linear regression [adjusted for maternal education, body mass index (BMI), fruit and vegetables (F&V) intake and child's BMI z-score]. Principal component analysis defined a three-factor structure explaining 58% of the total variance of maternal child-feeding patterns: perceived monitoring - representing mothers with higher levels of monitoring, perceived responsibility and overt control; restriction - characterizing mothers with higher covert control, restriction and concerns about child's weight; pressure to eat - identifying mothers with higher levels of pressure to eat and overt control. Lower socioeconomic status, better health perception, higher F&V intake and offspring cohabitation were associated with more 'perceived monitoring' mothers. Higher maternal F&V intake and depression were associated with more 'restrictive' mothers. Younger mothers, less educated, with poorer health perception and offspring cohabiting, were associated with higher use of 'pressure to eat'. Maternal socioeconomic indicators and family environment were more associated with perceived monitoring and pressure to eat, whereas maternal health behavioural characteristics were mainly associated with restriction. These findings will be helpful in future research and public health programmes on child-feeding patterns. PMID:24697990

    One in six children entering school experiences developmental delay. Maternal mental health represents one of the earliest, modifiable influences in a child's life. The objective of the review was to evaluate the association between maternal mental health and school-age child development, and we hypothesized there would be a negative association. Five databases were searched (Embase, CINAHL, Eric, PsycInfo, Medline). Key journals and reference lists were hand-searched. Two reviewers assessed studies based on inclusion criteria: (1) the exposure was any form of maternal mental health occurring during pregnancy or postpartum periods; (2) the outcome was child development (>48 months to 8 years); (3) the study recruited participants from developed countries; and (4) publication was in English between January, 1990 and December, 2012. Disagreements were resolved by consensus. Study quality was assessed by two reviewers using the Scottish Intercollegiate Guideline Network and disagreements were resolved by consensus. Data extraction was conducted by one reviewer using standardized forms. Maternal mental health problems in pregnancy and/or the postpartum period increased the likelihood that school-age children experienced suboptimal global, behavioral, cognitive, and socio-emotional development. The findings highlight the need for maternal mental health assessment during the prenatal, postnatal, and early childhood periods. PMID:24352625

    A study of 893 births was undertaken to determine the incidence of prolonged neonatal jaundice. 55% of these babies were breast feeding on discharge from the maternity hospital. Jaundice lasting for 3 weeks or more was found in 12 breast-fed term babies (2-4% of all breast-fed babies), and in no bottle-fed infant. 3 of the jaundiced babies gained weight poorly in the first 3 weeks of life, but after that age failure to thrive was not associated with the prolonged jaundice. The hyperbilirubinaemia, which persisted in 11 infants from between 21 to 80 days (mean 39 days), was due to elevations in both conjugated and unconjugated fractions. PMID:686778

    Sudden infant death syndrome (SIDS), neonatal deaths, and deaths from infection are higher among Indigenous Australians. This study aimed to determine the effects of inflammatory responses and exposure to cigarette smoke, two important factors associated with sudden death in infancy, on preterm birth, and birth weight in a cohort of Indigenous mothers. Indigenous Australian women (n = 131) were recruited as part of a longitudinal study while attending antenatal care clinics during pregnancy; blood samples were collected up to three times in pregnancy. Serum cotinine, indicating exposure to cigarette smoke, was detected in 50.4% of mothers. Compared with non-Indigenous women, the cohort had 10 times the prevalence of antibodies to Helicobacter pylori (33 vs. 3%). Levels of immunoglobulin G, antibodies to H. pylori, and C-reactive protein (CRP) were all inversely correlated with gestational age (P < 0.05). CRP levels were positively associated with maternal body mass index (BMI; ρ = 0.449, P = 0.001). The effects of cigarette smoke (cotinine) and inflammation (CRP) were assessed in relation to risk factors for SIDS: gestational age at delivery and birth weight. Serum cotinine levels were negatively associated with birth weight (ρ = −0.37, P < 0.001), this correlation held true for both male (ρ = −0.39, P = 0.002) and female (ρ = −0.30, P = 0.017) infants. Cotinine was negatively associated with gestational age at delivery (ρ = −0.199, P = 0.023). When assessed by fetal sex, this was significant only for males (ρ = −0.327, P = 0.011). CRP was negatively associated with gestational age at delivery for female infants (ρ = −0.46, P < 0.001). In contrast, maternal BMI was significantly correlated with birth weight. These data highlight the importance of putting programs in place to reduce cigarette smoke exposure in pregnancy and to treat women with chronic infections such as H. pylori to

    Offspring of older mothers are at increased risk of adverse birth outcomes, childhood cancers, type 1 diabetes, and neurodevelopmental disorders. The underlying biologic mechanisms for most of these associations remain obscure. One possibility is that maternal aging may produce lasting changes in the epigenetic features of a child’s DNA. To test this, we explored the association of mothers’ age at pregnancy with methylation in her offspring, using blood samples from 890 Norwegian newborns and measuring DNA methylation at more than 450,000 CpG sites across the genome. We examined replication of a maternal-age finding in an independent group of 1062 Norwegian newborns, and then in 200 US middle-aged women. Older maternal age was significantly associated with reduced methylation at four adjacent CpGs near the 2nd exon of KLHL35 in newborns (p-values ranging from 3x10-6 to 8x10-7). These associations were replicated in the independent set of newborns, and replicated again in women 40 to 60 years after their birth. This study provides the first example of parental age permanently affecting the epigenetic profile of offspring. While the specific functions of the affected gene are unknown, this finding opens the possibility that a mother’s age at pregnancy could affect her child’s health through epigenetic mechanisms.

    Childbirth is a major experience in a woman's life, but the relation between childbirth experiences and later mother-infant outcomes has been understudied. This study examined the relation between mode of delivery and subjective birth experience (e.g., perception of control, social support during labor and delivery), and mothers' descriptions of their babies and their maternal self-esteem, both powerful predictors of maternal caregiving behavior. This study had three questions: (a) Do mode of delivery and subjective birth experience predict mothers' descriptions of their babies and maternal self-esteem? (b) Are the effects of mode of delivery on mothers' descriptions and maternal self-esteem mediated by subjective birth experience? (c) Does infant age moderate any of these pathways? The sample consisted of 269 mothers of full-term, healthy infants who gave birth in the year prior to the study. Mode of delivery showed a direct effect on how mothers describe their babies, but not maternal self-esteem, which was not mediated by subjective birth experience. Subjective birth experience had direct effects on both outcomes. Infant age did not moderate any of these pathways. Results point to the subjective aspects of childbirth as important components of women's experience of labor and delivery. Implications are discussed. PMID:25704337

    OBJECTIVE The aim if the study was to investigate whether children born to older mothers have an increased risk of type 1 diabetes by performing a pooled analysis of previous studies using individual patient data to adjust for recognized confounders. RESEARCH DESIGN AND METHODS Relevant studies published before June 2009 were identified from MEDLINE, Web of Science, and EMBASE. Authors of studies were contacted and asked to provide individual patient data or conduct prespecified analyses. Risk estimates of type 1 diabetes by maternal age were calculated for each study, before and after adjustment for potential confounders. Meta-analysis techniques were used to derive combined odds ratios and to investigate heterogeneity among studies. RESULTS Data were available for 5 cohort and 25 case-control studies, including 14,724 cases of type 1 diabetes. Overall, there was, on average, a 5% (95% CI 2–9) increase in childhood type 1 diabetes odds per 5-year increase in maternal age (P = 0.006), but there was heterogeneity among studies (heterogeneity I2 = 70%). In studies with a low risk of bias, there was a more marked increase in diabetes odds of 10% per 5-year increase in maternal age. Adjustments for potential confounders little altered these estimates. CONCLUSIONS There was evidence of a weak but significant linear increase in the risk of childhood type 1 diabetes across the range of maternal ages, but the magnitude of association varied between studies. A very small percentage of the increase in the incidence of childhood type 1 diabetes in recent years could be explained by increases in maternal age. PMID:19875616

    Trisomy 16 is the most common human trisomy, occurring in > or = 1% of all clinically recognized pregnancies. It is thought to be completely dependent on maternal age and thus provides a useful model for studying the association of increasing maternal age and nondisjunction. We have been conducting a study to determine the parent and meiotic stage of origin of trisomy 16 and the possible association of nondisjunction and aberrant recombination. In the present report, we summarize our observations on 62 spontaneous abortions with trisomy 16. All trisomies were maternally derived, and in virtually all the error occurred at meiosis I. In studies of genetic recombination, we observed a highly significant reduction in recombination in the trisomy-generating meioses by comparison with normal female meioses. However, most cases of trisomy 16 had at least one detectable crossover between the nondisjoined chromosomes, indicating that it is reduced--and not absent--recombination that is the important predisposing factor. Additionally, our data indicate an altered distribution of crossing-over in trisomy 16, as we rarely observed crossovers in the proximal long and short arms. Thus, it may be that, at least for trisomy 16, the association between maternal age and trisomy is due to diminished recombination, particularly in the proximal regions of the chromosome.

    This study leveraged data from the Minnesota Longitudinal Study of Risk and Adaptation (N = 243) to investigate the predictive significance of maternal sensitivity during the first three years of life for social and academic competence through age 32 years. Structural model comparisons replicated previous findings that early maternal sensitivity predicts social skills and academic achievement through mid-adolescence in a manner consistent with an Enduring Effects model of development and extended these findings using heterotypic indicators of social (effectiveness of romantic engagement) and academic competence (educational attainment) during adulthood. Although early socioeconomic factors and child gender accounted for the predictive significance of maternal sensitivity for social competence, covariates did not fully account for associations between early sensitivity and academic outcomes PMID:25521785

    In Brazil, there is a lack of complete records on death certificates, and its reliability is questioned, especially for causes attributed to pregnancy and childbirth. We investigated, based on death certificates of women in reproductive age, any fields for identifying maternal deaths. Documentary research, conducted in hospital records. We analyzed in death certificates, maternal and no maternal deaths, inconclusive deaths and hidden deaths. To analyze the underlying causes of death we used ICD 10th Revision. Of the 301 death certificates reviewed, 60% had the fields 43/44 completed, and 40% had these fields blank and/or ignored. We found 58.5% of no maternal deaths, 2% of maternal deaths and 39.5% inconclusive. The analysis of inconclusive deaths allowed us to classify 4.3% as hidden deaths. To overcome the incompletitudes of civil registries, it is necessary that all health professionals be committed to the reliability of the information, so the priority target could be reached.

    Background Several risk factors are associated with the incidence of human stillbirths. The prevention of stillbirths in women is a pressing clinical problem. Methods We reviewed 402 pathology records of fetal loss occurring in a large baboon (Papio spp.) colony during a 15-year period. Clinical histories of 565 female baboons with one or more fetal losses during a 20-year period were analyzed for weight, age, and reproductive history. Results Fetal loss was most common at term (35.57%) and preterm (28.61%) and less common in the first half of gestation (11.20%) and post-term (5.22%). Greater maternal weight, older age, history of stillbirth and higher parity were independent predictors for stillbirth. An exponential increase in the incidence of fetal loss was observed beginning at age 14 years in baboons. Conclusion Fetal loss and maternal risk factors associated with stillbirths in baboons were similar to those documented in women. PMID:19017195

    Early maternal support has been shown to promote specific gene expression, neurogenesis, adaptive stress responses, and larger hippocampal volumes in developing animals. In humans, a relationship between psychosocial factors in early childhood and later amygdala volumes based on prospective data has been demonstrated, providing a key link between early experience and brain development. Although much retrospective data suggests a link between early psychosocial factors and hippocampal volumes in humans, to date there has been no prospective data to inform this potentially important public health issue. In a longitudinal study of depressed and healthy preschool children who underwent neuroimaging at school age, we investigated whether early maternal support predicted later hippocampal volumes. Maternal support observed in early childhood was strongly predictive of hippocampal volume measured at school age. The positive effect of maternal support on hippocampal volumes was greater in nondepressed children. These findings provide prospective evidence in humans of the positive effect of early supportive parenting on healthy hippocampal development, a brain region key to memory and stress modulation.

    Identification of modifiable risk factors is gravely needed to prevent adverse prostate health outcomes. We previously developed a murine precancer model in which exposure to maternal obesity stimulated prostate hyperplasia in offspring. Here, we used generalized linear modeling to evaluate the influence of additional environmental covariates on prostate hyperplasia. As expected from our previous work, the model revealed that aging and maternal diet-induced obesity (DIO) each correlated with prostate hyperplasia. However, prostate hyperplasia was not correlated with the length of maternal DIO. Cage density positively associated with both prostate hyperplasia and offspring body weight. Expression of the glucocorticoid receptor in prostates also positively correlated with cage density and negatively correlated with age of the animal. Together, these findings suggest that prostate tissue was adversely patterned during early life by maternal overnutrition and was susceptible to alteration by environmental factors such as cage density. Additionally, prostate hyperplasia may be acutely influenced by exposure to DIO, rather than occurring as a response to worsening obesity and comorbidities experienced by the mother. Finally, cage density correlated with both corticosteroid receptor abundance and prostate hyperplasia, suggesting that overcrowding influenced offspring prostate hyperplasia. These results emphasize the need for multivariate regression models to evaluate the influence of coordinated variables in complicated animal systems. PMID:26243546

    Introduction Five hundred thousand maternal deaths occur each year worldwide, many of which are in developing countries. The maternal mortality rate is a measure that demonstrates the degree of adequacy of prenatal care and of economic and social conditions. The aim of this study was to determine the frequency and causes of pregnancy-related mortality rates in Yazd Province. Methods This cross-sectional study examined the maternal deaths related to pregnancy that were recorded in Yazd Province, Iran, from 2002 to 2011. All maternal deaths that occurred during pregnancy, during delivery, and 42 days after birth were analyzed in this study. The data were collected through a questionnaire, and both direct and indirect causes of maternal deaths were determined. Results Forty pregnancy-related deaths occurred in this period, and the maternal mortality rate was 20.8 deaths per 100,000 live births. The mean age of death in the mothers in this study was 29.17. Fifty-five percent of women of the women who died delivered their babies by cesarean section, and only 20% of them delivered their babies vaginally. Bleeding was the most common cause of maternal mortality (30%), and it was associated directly with maternal mortality. Furthermore 20% of the mothers died due to heart disease and cardiac complications, which were associated indirectly with maternal mortality. Conclusion Cesarean section and its complications were the main cause of death in many cases. Thus, providing a strategic plan to reduce the use of this procedure, educate mothers, and ensure adequate access to pre-maternal care and to care during pregnancy are the most important measures that can be taken to decrease the maternal mortality rate.

    Aneuploidy in human eggs is the leading cause of pregnancy loss and Down’s syndrome. Aneuploid eggs result from chromosome segregation errors when an egg develops from a progenitor cell, called an oocyte. The mechanisms that lead to an increase in aneuploidy with advanced maternal age are largely unclear. Here, we show that many sister kinetochores in human oocytes are separated and do not behave as a single functional unit during the first meiotic division. Having separated sister kinetochores allowed bivalents to rotate by 90 degrees on the spindle and increased the risk of merotelic kinetochore-microtubule attachments. Advanced maternal age led to an increase in sister kinetochore separation, rotated bivalents and merotelic attachments. Chromosome arm cohesion was weakened, and the fraction of bivalents that precociously dissociated into univalents was increased. Together, our data reveal multiple age-related changes in chromosome architecture that could explain why oocyte aneuploidy increases with advanced maternal age.

    Baby bottle tooth decay (BBTD) is a term applied to a specific form of rampant decay associated with inappropriate bottle or breast feeding of infants and young children. Although the prevalence of BBTD has been studied in individual ethnic groups, comparison studies are rare. Head Start children have frequently served as study subjects for assessing the prevalence of BBTD. The purpose of this study was to compare BBTD and caries prevalence among Head Start children who are members of four ethnic groups in five southwestern States. Age, residence, and fluoridation status were also compared for the total sample and ethnic categories. The sampling process was a stratified random site selection; it was used to obtain data on 1,230 children. This number constituted 3 percent of the children enrolled in Head Start in Public Health Service Region VI (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas) where the study was conducted. The criterion for determining the presence of BBTD was based on the number of carious deciduous maxillary incisors observed. The severity of the condition was reported as two of four and three of four of the target teeth affected. Thus, two levels of severity are reported. BBTD was prevalent in approximately 24 percent and 15 percent of the total sample, depending on the severity criterion used. Native American children had a significantly higher (P less than 0.05) prevalence than Hispanic, white, and black subjects. Rural children had significantly higher (P less than 0.05) prevalence of BBTD than nonrural children for all ethnic groups except whites. The prevalence of decayed and filled (df) surfaces of primary dentition was significantly greater for all rural than for non rural groups (P< 0.05).Children attending centers showed no significant differences based on fluoride status for the total sample or other variables. BBTD and caries prevalence increased with age. Studies are needed to identify predisposing factors among the ethnic

    In Western countries today, a growing number of women delay motherhood until their late 30s and even 40s, as they invest time in pursuing education and career goals before starting a family. This social trend results from greater gender equality and expanded opportunities for women and is influenced by the availability of contraception and assisted reproductive technologies (ART). However, advanced maternal age is associated with increased health risks, including infertility. While individual medical solutions such as ART and elective egg freezing can promote reproductive autonomy, they entail significant risks and limitations. We thus argue that women should be better informed regarding the risks of advanced maternal age and ART, and that these individual solutions need to be supplemented by a public health approach, including policy measures that provide women with the opportunity to start a family earlier in life without sacrificing personal career goals.

    Reported livebirth prevalence of Down syndrome (DS) may be affected by the maternal age distribution of the population, completeness of ascertainment, accuracy of diagnosis, extent of selective prenatal termination of affected pregnancies, and as yet unidentified genetic and environmental factors. To search for evidence of the latter, we reviewed all published reports in which it was possible to adjust both for effects of maternal age and for selective termination (where relevant). We constructed indices that allowed direct comparisons of prevalence rates after standardising for maternal age. Reference rates were derived from studies previously identified as having near complete ascertainment. An index value significantly different from 1 may result from random fluctuations, as well as from variations in the factors listed above. We found 49 population groups for which an index could be calculated. Methodological descriptions suggested that low values could often be attributed to under-ascertainment. A possible exception concerned African-American groups, though even among these most acceptable studies were compatible with an index value of 1. As we have reported elsewhere, there was also a suggestive increase in rates among US residents of Mexican or Central American origin. Nevertheless, our results suggest that "real" variation between population groups reported to date probably amounts to no more than +/-25%. However, reliable data in many human populations are lacking including, surprisingly, some jurisdictions with relatively advanced health care systems. We suggest that future reports of DS livebirth prevalence should routinely present data that allow calculation of an index standardised for maternal age and adjusted for elective prenatal terminations.

    Despite the best of intentions, we often act at the last minute when we are faced with a deadline. A recent recommendation by the English National Institute for Health and Clinical Excellence (NICE) to make In Vitro Fertilisation (IVF) available to women up to 42 years of age instead of 39 intends to offer more women the chance of pregnancy. Given what we know about behavioural responses to what is, in essence, a deadline, the policy could lead to procrastination and fewer wanted pregnancies. We examine how many women it would take to delay trying for a baby for this policy to result in fewer pregnancies. We take a cohort of 1000 women from age 34. If no women delay trying, the increased age on access to IVF results in 31 more pregnancies. Because of declining fertility with age, it would take only about a third of these women to delay trying for a baby until age 35 for there to be zero net benefits of increased IVF availability. If all women delayed by a year, the new policy will lead to 59 fewer pregnancies. We also estimate the implications for IVF treatment numbers as this has psychological and personal consequences. Our findings highlight how no policy sits in a behavioural vacuum and all policy decisions should consider the likely behavioural responses and incorporate them into their design and evaluation.

    OBJECTIVE: To analyze the characteristics of infant mortality at the extremes of maternal age. METHOD: Retrospective, cross-sectional quantitative study using data from Live Birth Certificates, Death Certificates and from Child Death Investigation records in Londrina, Paraná, in the years of 2000-2009. RESULTS: During the 10-year study period , there were 176 infant deaths among mothers up to 19 years of age, and 113 deaths among mothers aged 35 years or more. The infant mortality rate among young mothers was 14.4 deaths per thousand births, compared to 12.9 deaths in the other age group. For adolescent mothers, the following conditions prevailed: lack of a stable partner (p<0.001), lack of a paid job (p<0.001), late start of prenatal care in the second trimester of pregnancy (p<0.001), fewer prenatal visits (p<0.001) and urinary tract infections (p<0.001). On the other hand, women aged 35 or more had a higher occurrence of hypertension during pregnancy (p<0.001), and of surgical delivery (p<0.001). Regarding the underlying cause of infant death, congenital anomalies prevailed in the group of older mothers (p=0.002), and external causes were predominant in the group of young mothers (p=0.019). CONCLUSION: Both age groups deserve the attention of social services for maternal and child health, especially adolescent mothers, who presented a higher combination of factors deemed hazardous to the child's health.

    Known sex specific differences in fetal, neonatal morbidity and mortality have been documented. Sex differences also exist in birth-weight centile with males being larger than females at birth. However, these sex differences are not fully explored when studying passive measles immunity acquired by babies from their mothers. Moreover, the mechanisms that confer these sex differences are to a large extent unknown. Therefore, this study assessed sex of babies as a determinant of measles immunoglobulin G acquisition from their respective mothers. One hundred and seventy four newborn babies were enrolled in this study. Enzyme linked immunosorbent assay was used to measure maternal measles antibodies (MMA) from sera collected from these babies at birth. Gestational age of the newborn babies was determined using the Nagele rule, ultrasound scan reports and the Dubowitz criteria. Sex and mean MMA of these babies was compared using the Student’s t test. Significant comparison existed between mean MMA and sex of post term babies (P = 0.000), such that post term males had higher levels of MMA than females. However, overall sex and mean MMA comparison of these babies was not significant (P = 0.977). There were more MMA in male post term babies relative to their female peers; however, overall sex comparison of MMA was not significant. Therefore, there is the need for further study.

    To examine the combined effect of birth weight, mothers' education and prenatal smoking on psychometrically measured intelligence at school age 1,822 children born in 1992-1999 and attending the first six grades from 45 schools representing all of the fifteen Estonian counties with information on birth weight, gestational age and mother's age, marital status, education, parity and smoking in pregnancy, and intelligence tests were studied. The scores of Raven's Standard Progressive Matrices were related to the birth weight: in the normal range of birth weight (>or=2500 g) every 500 g increase in birth weight was accompanied by around 0.7-point increase in IQ scores. A strong association between birth weight and IQ remained even if gestational age and mother's age, marital status, education, place of residence, parity and smoking during pregnancy have been taken into account. Maternal prenatal smoking was accompanied by a 3.3-point deficit in children's intellectual abilities. Marriage and mother's education had an independent positive correlation with offspring intelligence. We concluded that the statistical effect of birth weight, maternal education and smoking in pregnancy on offspring's IQ scores was remarkable and remained even if other factors have been taken into account.

    The relationship between advanced maternal age and increased risk of trisomic offspring is well know clinically but not clearly understood at the level of the oocyte. A total of 383 oocytes that failed fertilization from 107 patients undergoing in vitro fertilization were analyzed by FISH using X-, 18-, and 13/21-chromosome probes simultaneously. The corresponding polar bodies were also analyzed in 188 of these oocytes. The chromosomes in the oocyte and first polar body complement each other and provide an internal control to differentiate between aneuploidy and technical errors. Two mechanisms of nondisjunction were determined. First, nondisjunction of bivalent chromosomes resulting in two univalents going to the same pole and, second, nondisjunction by premature chromatid separation (predivision) of univalent chromsomes producing either a balanced (2 + 2) or unbalanced (3 + 1) distribution of chromatids into the first polar body and M-II oocytes. Balanced predivision of chromatids, previously proposed as a major mechanism of aneuploidy, was found to increase significantly with time in culture (P < .005), which suggests that this phenomenon should be interpreted carefully. Unbalanced predivision and classical nondisjunction were unaffected by oocyte aging. In comparing oocytes from women <35 years of age with oocytes from women {ge}40 years of age, a significant increase (P < .001) in nondisjunction of full dyads was found in the oocytes with analyzable polar bodies and no FISH errors. Premature predivision of chromatids was also found to cause nondisjunction, but it did not increase with maternal age. 44 refs., 3 figs., 2 tabs.

    Germline mutations are the source of evolution and contribute substantially to many health-related processes. Here we use whole-genome deep sequencing data from 693 parents–offspring trios to examine the de novo point mutations (DNMs) in the offspring. Our estimate for the mutation rate per base pair per generation is 1.05 × 10−8, well within the range of previous studies. We show that maternal age has a small but significant correlation with the total number of DNMs in the offspring after controlling for paternal age (0.51 additional mutations per year, 95% CI: 0.29, 0.73), which was not detectable in the smaller and younger parental cohorts of earlier studies. Furthermore, while the total number of DNMs increases at a constant rate for paternal age, the contribution from the mother increases at an accelerated rate with age.These observations have implications related to the incidence of de novo mutations relating to maternal age.

    The effects of maternal employment on children's health are theoretically ambiguous and challenging to identify. There are trade-offs between income and time, and a mother's decision to work reflects, in part, her children's health and her underlying preferences. I utilize exogenous variation in each child's youngest sibling's eligibility for kindergarten as an instrument. Using the restricted-access National Health Interview Survey (1985-2004), I identify the effects on overnight hospitalizations, asthma episodes, and injuries/poisonings for children ages 7-17. Maternal employment increases the probability of each adverse health event by nearly 200 percent. These effects are robust and do not reflect a non-representative local effect. PMID:21316779

Methods We examined data from women without a prior cesarean who responded to Listening to Mothers III, a nationally representative survey of women who had given birth between July 2011 and June 2012 (n=1,960). We estimated the effect of having a suspected large baby (SLB) on the odds of six labor and delivery outcomes. Results Nearly one-third (31.2%) of women were told by their maternity care providers that their babies might be getting “quite large”; however, only 9.9% delivered a baby weighing ≥4,000 grams (19.7% among mothers with SLBs, 5.5% without). Women with SLBs had increased adjusted odds of medically-induced labor (AOR 1.9; 95% CI: 1.4–2.6), attempted self-induced labor (AOR 1.9; 95% CI: 1.4–2.7), and use of epidural analgesics (AOR 2.0; 95% CI: 1.4–2.9). No differences were noted for overall cesarean rates, although women with SLBs were more likely to ask for (AOR 4.6; 95% CI: 2.8–7.6) and have planned (AOR 1.8; 95% CI: 1.0–4.5) cesarean deliveries. These associations were not affected by adjustment for gestational age and birthweight. Conclusion Only one in five US women who were told that their babies might be getting quite large actually delivered infants weighing ≥4,000 grams. However, the suspicion of a large baby was associated with an increase in perinatal interventions, regardless of actual fetal size. PMID:26140835

    Early life adversity, such as postnatal maternal separation (MS), play a central role in the development of psychopathologies during individual ontogeny. In this study, we investigated the effects of repeated MS (4 h per day from postnatal day (PND) 1–21) on the brain-derived neurotrophic factor (BDNF) expression in the medial prefrontal cortex (mPFC), the nucleus accumbens (NAc) and the hippocampus of male and female juvenile (PND 21), adolescent (PND 35) and young adult (PND 56) Wistar rats. The results indicated that MS increased BDNF in the CA1 and the dentate gyrus (DG) of adolescent rats as well as in the DG of young adult rats. However, the expression of BDNF in the mPFC in the young adult rats was decreased by MS. Additionally, in the hippocampus, there was decreased BDNF expression with age in both the MS and non separated rats. However, in the mPFC, the BDNF expression was increased with age in the non separated rats; nevertheless, the BDNF expression was significantly decreased in the MS young adult rats. In the NAc, the BDNF expression was increased with age in the male non-maternal separation (NMS) rats, and the young adult female MS rats had less BDNF expression than the adolescent female MS rats. The present study shows unique age-differently changes on a molecular level induced by MS and advances the use of MS as a valid animal model to detect the underlying neurobiological mechanisms of mental disorders.

    Objective This study investigated the association between maternal ages at birth of last child and the likelihood of survival to advanced ages. Methods A nested case-control study using Long Life Family Study (LLFS) data. Three hundred and eleven women who survived past the oldest 5th percentile of survival according to birth cohort matched life tables were identified as cases and 151 women who died at ages younger than the top 5th percentile of survival were identified as controls. A Bayesian mixed-effect logistic regression model was used to estimate the association between maternal age at birth of last child and exceptional longevity among these 462 women. Results A significant association for later maternal age was found whereby women who had their last child beyond the age of 33 years had twice the odds of survival to the top 5th percentile of survival of their birth cohorts compared to women who had their last child by age 29 (OR=2.08, 95%CI 1.13; 3.92 for age between 33 and 37 years and OR=1.92, 95% CI 1.03; 3.68 for older age). Conclusion The study supports the findings from other studies demonstrating a positive association between older maternal age and greater odds of the mother surviving to unusually old age.

    Maternal obesity is linked with adverse outcomes for mothers and babies. To get an overview of risks related to obesity in pregnant women, a systematic review of reviews was conducted. For inclusion, reviews had to compare pregnant women of healthy weight with women with obesity, and measure a health outcome for mother and/or baby. Authors conducted full-text screening, quality assurance using the AMSTAR tool and data extraction steps in pairs. Narrative analysis of the 22 reviews included show gestational diabetes, pre-eclampsia, gestational hypertension, depression, instrumental and caesarean birth, and surgical site infection to be more likely to occur in pregnant women with obesity compared with women with a healthy weight. Maternal obesity is also linked to greater risk of preterm birth, large-for-gestational-age babies, foetal defects, congenital anomalies and perinatal death. Furthermore, breastfeeding initiation rates are lower and there is greater risk of early breastfeeding cessation in women with obesity compared with healthy weight women. These adverse outcomes may result in longer duration of hospital stay, with concomitant resource implications. It is crucial to reduce the burden of adverse maternal and foetal/child outcomes caused by maternal obesity. Women with obesity need support to lose weight before they conceive, and to minimize their weight gain in pregnancy. PMID:26016557

    The objective of this study is to determine the influence of maternal health literacy and child's age on participation in social welfare programs benefiting children. In a longitudinal prospective cohort study of 560 Medicaid-eligible mother-infant dyads recruited in Philadelphia, maternal health literacy was assessed using the test of functional health literacy in adults (short version). Participation in social welfare programs [Temporary Assistance to Needy Families (TANF), Supplemental Nutrition Assistance Program (SNAP), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), child care subsidy, and public housing] was self-reported at child's birth, and at the 6, 12, 18, 24 month follow-up interviews. Generalized estimating equations quantified the strength of maternal health literacy as an estimator of program participation. The mothers were primarily African-Americans (83%), single (87%), with multiple children (62%). Nearly 24% of the mothers had inadequate or marginal health literacy. Children whose mothers had inadequate health literacy were less likely to receive child care subsidy (adjusted OR = 0.54, 95% CI 0.34-0.85) than children whose mothers had adequate health literacy. Health literacy was not a significant predictor for TANF, SNAP, WIC or housing assistance. The predicted probability for participation in all programs decreased from birth to 24 months. Most notably, predicted WIC participation declined rapidly after age one. During the first 24 months, mothers with inadequate health literacy could benefit from simplified or facilitated child care subsidy application processes. Targeted outreach and enrollment efforts conducted by social welfare programs need to take into account the changing needs of families as children age. PMID:23990157

    Down syndrome caused by meiotic nondisjunction of chromosome 21 in humans, is well known to be associated with advanced maternal age, but success in identifying and understanding other risk factors has been limited. Recently published work in a U.S. population suggested intriguing interactions between the maternal age effect and altered recombination patterns during meiosis, but some of the results were counter-intuitive. We have tested these hypotheses in a population sample from India, and found that essentially all of the results of the U.S. study are replicated even in our ethnically very different population. We examined meiotic recombination patterns in a total of 138 families from the eastern part of India, each with a single free trisomy 21 child. We genotyped each family with a set of STR markers using PCR and characterized the stage of origin of nondisjunction and the recombination pattern of maternal chromosome 21 during oogenesis. Our sample contains 107 maternal meiosis I errors and 31 maternal meiosis II errors and we subsequently stratified them with respect to maternal age and the number of detectable crossover events. We observed an association between meiosis I nondisjuncion and recombination in the telomeric 5.1 Mb of chromosome 21. By contrast, in meiosis II cases we observed preferential peri-centromeric exchanges covering the proximal 5.7 Mb region, with interaction between maternal age and the location of the crossover. Overall reduction of recombination irrespective of maternal age is also evident in meiosis I cases. Our findings are very consistent with previously reported data in a U.S. population and our results are the first independent confirmation of those previous reports. This not only provides much needed confirmation of previous results, but it suggests that the genetic etiology underlying the occurrence of trisomy 21 may be similar across human populations.

    Background Observational epidemiological studies indicate that maternal height is associated with gestational age at birth and fetal growth measures (i.e., shorter mothers deliver infants at earlier gestational ages with lower birth weight and birth length). Different mechanisms have been postulated to explain these associations. This study aimed to investigate the casual relationships behind the strong association of maternal height with fetal growth measures (i.e., birth length and birth weight) and gestational age by a Mendelian randomization approach. Methods and Findings We conducted a Mendelian randomization analysis using phenotype and genome-wide single nucleotide polymorphism (SNP) data of 3,485 mother/infant pairs from birth cohorts collected from three Nordic countries (Finland, Denmark, and Norway). We constructed a genetic score based on 697 SNPs known to be associated with adult height to index maternal height. To avoid confounding due to genetic sharing between mother and infant, we inferred parental transmission of the height-associated SNPs and utilized the haplotype genetic score derived from nontransmitted alleles as a valid genetic instrument for maternal height. In observational analysis, maternal height was significantly associated with birth length (p = 6.31 × 10−9), birth weight (p = 2.19 × 10−15), and gestational age (p = 1.51 × 10−7). Our parental-specific haplotype score association analysis revealed that birth length and birth weight were significantly associated with the maternal transmitted haplotype score as well as the paternal transmitted haplotype score. Their association with the maternal nontransmitted haplotype score was far less significant, indicating a major fetal genetic influence on these fetal growth measures. In contrast, gestational age was significantly associated with the nontransmitted haplotype score (p = 0.0424) and demonstrated a significant (p = 0.0234) causal effect of every 1 cm increase in maternal

    Objective: The aim of this study was to determine the effect of maternal anthropometry and metabolic parameters on neonatal anthropometry. Materials and Methods: This observational cross-sectional study was conducted from January 2008 to June 2009 at a single tertiary care center. Maternal anthropometry and metabolic parameters like fasting serum insulin, lipid profile, and random blood glucose were estimated in 50 pregnant women at term. Detailed anthropometry of the neonates was performed. Results: Large for gestational age (LGA) babies had higher maternal body mass index (BMI), fasting serum insulin, and cord blood insulin levels, and lower maternal high density lipoprotein (HDL) compared to appropriate for gestational age (AGA) group (P < 0.001). Among the maternal parameters, BMI, gestational age, fasting serum insulin, and random blood sugar (RBS) had significant positive correlation, while HDL had negative correlation with birth weight (P < 0.05). However, only maternal BMI was the significant predictor of neonatal birth weight on multiple regression analysis (ß = 0.340, P = 0.01). Conclusion: The BMI of glucose-tolerant mother is more important than metabolic parameters in determining the birth weight of term babies. PMID:23087859

    One hundred and fifty six babies with birth weight between 1500-2000 g and 103 full term-appropriate for gestational age (FT-AGA) babies delivered at University Hospital, District Hospital and village homes were included for a comparative study of mortality, morbidity and growth pattern. The low birth weight (LBW) babies from the three centres had similar birth weight and gestational age. Neonatal mortality rates for the LBW babies were similar at the three centres. The main cause of death were infections and aspiration with rates again being similar. Diarrhea and respiratory tract infections were common causes of morbidity. The mortality rates for the LBW babies were significantly higher as compared to FT-AGA babies irrespective of the place of delivery. The incidence of morbidities like diarrhea and respiratory infections were also higher in LBW babies. However, the differences were statistically significant mostly in the preterm group. The weight gain of all LBW babies was similar up to 3 months of age. The findings of an identical outcome for the LBW babies at village level to those managed at hospitals is an encouraging trend to increasing domiciliary care for LBW babies. PMID:8406701

    Methyl-donor nutrients are substrates for methylation reactions involved in neurodevelopment processes. The role of maternal intake of these nutrients on cognitive performance of the offspring is poorly understood. We examined the associations of maternal intake of folate, vitamin B12, choline, betaine and methionine during the first and second trimesters of pregnancy, with tests of cognitive performance in the offspring at 3 years of age using data from 1210 participants in Project Viva, a prospective pre-birth cohort study in Massachusetts. We assessed nutrient intake with the use of food frequency questionnaires. Children's cognition at age 3 years was evaluated with the Peabody Picture Vocabulary Test III (PPVT-III) and visual-motor skills with the Wide Range Assessment of Visual Motor Abilities test. In multivariable models adjusting for potential sociobehavioural and nutritional confounders, for each 600 µg/day increment in total folate intake during the first trimester, PPVT-III score at age 3 years was 1.6 points [95% confidence interval (CI) 0.1, 3.1; P = 0.04] higher. There was a weak inverse association between vitamin B12 intake during the second trimester and PPVT-III scores [-0.4 points per 2.6 µg/day; 95% CI -0.8, -0.1; P = 0.01]. We did not find associations between choline, betaine or methionine and cognitive outcomes at this age. Results of this study suggest that higher intake of folate in early pregnancy is associated with higher scores on the PPVT-III, a test of receptive language that predicts overall intelligence, at age 3 years.

    This study examined non-maternal involvement in feeding during the first two years of life and its association with breastfeeding duration, early introduction of complementary foods, and dietary intakes of selected foods and beverages. Data were from the Infant Care, Feeding and Risk of Obesity Study, a cohort of 217 low-income, African-American mother-infant dyads, followed from 3-18 months postpartum. Non-maternal caregivers (NMCs) were defined as persons involved in feeding an infant/toddler 50% or more of the total daily feedings. Use of any NMC and the type of NMC was tabulated for each study visit (3, 6, 9, 12, and 18 months). At each time point, more than half of all households reported a NMC. Fathers, grandmothers, and licensed childcare providers were the most common types of NMCs. In longitudinal models adjusted for confounding variables, NMC use was associated with a decreased likelihood of continued breastfeeding, and an increased likelihood of infants and toddlers consuming juice or whole fruit. Given the high prevalence of non-maternal involvement in feeding, interventions targeting multiple family members are warranted as they are likely to be more effective than those targeting the mother alone.

    Accepted indications for exploration in obstetrical brachial plexus palsy (OBPP) vary by center. Most agree that full elbow flexion against gravity at nine months of age implies high chance of spontaneous recovery and thus excludes a baby from surgical intervention. However, there are certain movements of the shoulder and forearm that may not be used frequently by the infant, but are extremely important functionally as they grow. These movements are difficult to assess in a baby and may lead to some clinicians to recommend conservative treatment, when this cohort of infants may in fact benefit substantially from surgery. A retrospective review was conducted on all infants managed surgically at the Brachial Plexus Center of a major children's hospital from 2009 to 2014. Further analysis identified five patients who had near-normal AMS scores for elbow flexion but who had weakness of shoulder abduction, flexion, external rotation, and/or forearm supination. In contrast to standard conservative management, this cohort underwent exploration, C5-6 neuroma excision, and sural nerve grafting. Data analysis was performed on this group to look for overall improvement in function. During an average follow-up period of 29 months, all patients made substantial gains in motor function of the shoulder and forearm, without loss of elbow flexion or extension, or worsening of overall outcome. In select infants with brachial plexus injuries but near-normal AMS scores for elbow flexion, surgical intervention may be indicated to achieve the best functional outcome. PMID:26806089

    It was hypothesized that the relationship between maternal age and infant birthweight varies significantly across neighborhoods and that such variation can be predicted by neighborhood characteristics. We analyzed 229,613 singleton births of mothers aged 20–45 from Chicago, USA in 1997–2002. Random coefficient models were used to estimate the between-neighborhood variation in age-birthweight slopes, and both intercepts- and-slopes-as-outcomes models were used to evaluate area-level predictors of such variation. The crude maternal age-birthweight slopes for neighborhoods ranged from a decrease of 17 grams to an increase of 10 grams per year of maternal age. Adjustment for individual-level covariates reduced but did not eliminate this between-neighborhood variation. Concentrated poverty was a significant neighborhood-level predictor of the age-birthweight slope, explaining 44.4 percent of the between-neighborhood variation in slopes. Neighborhoods of higher economic disadvantage showed a more negative age-birthweight slope. The findings support the hypothesis that the relationship between maternal age and birthweight varies between neighborhoods. Indicators of neighborhood disadvantage help to explain such differences.

    Variability in demographic traits between individuals within populations has profound implications for both evolutionary processes and population dynamics. Parental effects as a source of non-genetic inheritance are important processes to consider to understand the causes of individual variation. In iteroparous species, parental age is known to influence strongly reproductive success and offspring quality, but consequences on an offspring fitness component after independence are much less studied. Based on 37 years longitudinal monitoring of a long-lived seabird, the wandering albatross, we investigate delayed effects of parental age on offspring fitness components. We provide evidence that parental age influences offspring performance beyond the age of independence. By distinguishing maternal and paternal age effects, we demonstrate that paternal age, but not maternal age, impacts negatively post-fledging offspring performance. PMID:27053738

    OBJECTIVE—The purpose of this study was to examine age of diabetes diagnosis in youth who have a parent with diabetes by diabetes type and whether the parent's diabetes was diagnosed before or after the youth's birth. RESEARCH DESIGN AND METHODS—The cohort comprised SEARCH for Diabetes in Youth Study participants (diabetes diagnosis 2001–2005) with a diabetic parent. SEARCH is a multicenter survey of youth with diabetes diagnosed before age 20 years. RESULTS—Youth with type 2 diabetes were more likely to have a parent with either type 1 or type 2 diabetes (mother 39.3%; father 21.2%) than youth with type 1 diabetes (5.3 and 6.7%, respectively, P < 0.001 for each). Type 2 diabetes was diagnosed 1.68 years earlier among those exposed to diabetes in utero (n = 174) than among those whose mothers’ diabetes was diagnosed later (P = 0.018, controlled for maternal diagnosis age, paternal diabetes, sex, and race/ethnicity). Age at diagnosis of type 1 diabetes for 269 youth with and without in utero exposure did not differ significantly (difference 0.96 year, P = 0.403 after adjustment). Controlled for the father's age of diagnosis, father's diabetes before the child's birth was not associated with age at diagnosis (P = 0.078 for type 1 diabetes; P = 0.140 for type 2 diabetes). CONCLUSIONS—Type 2 diabetes was diagnosed at younger ages among those exposed to hyperglycemia in utero. Among youth with type 1 diabetes, the effect of the intrauterine exposure was not significant when controlled for mother's age of diagnosis. This study helps explain why other studies have found higher age-specific rates of type 2 diabetes among offspring of women with diabetes. PMID:18694977

    Background Prior research reports inverse associations between maternal prenatal urinary phthalate metabolite concentrations and mental and motor development in preschoolers. No study evaluated whether these associations persist into school age. Methods In a follow up of 328 inner-city mothers and their children, we measured prenatal urinary metabolites of di-n-butyl phthalate (DnBP), butylbenzyl phthalate (BBzP), di-isobutyl phthalate (DiBP), di-2-ethylhexyl phthalate and diethyl phthalate in late pregnancy. The Wechsler Intelligence Scale for Children, 4th edition was administered at child age 7 years and evaluates four areas of cognitive function associated with overall intelligence quotient (IQ). Results Child full-scale IQ was inversely associated with prenatal urinary metabolite concentrations of DnBP and DiBP: b = −2.69 (95% confidence interval [CI] = −4.33, −1.05) and b = −2.69 (95% CI = −4.22, −1.16) per log unit increase. Among children of mothers with the highest versus lowest quartile DnBP and DiBP metabolite concentrations, IQ was 6.7 (95% CI = 1.9, 11.4) and 7.6 (95% CI = 3.2, 12.1) points lower, respectively. Associations were unchanged after control for cognition at age 3 years. Significant inverse associations were also seen between maternal prenatal metabolite concentrations of DnBP and DiBP and child processing speed, perceptual reasoning and working memory; DiBP and child verbal comprehension; and BBzP and child perceptual reasoning. Conclusion Maternal prenatal urinary metabolite concentrations measured in late pregnancy of DnBP and DiBP are associated with deficits in children’s intellectual development at age 7 years. Because phthalate exposures are ubiquitous and concentrations seen here within the range previously observed among general populations, results are of public health significance. PMID:25493564

    The purpose of this study was to investigate whether maternal intimate partner violence (IPV) victimization during pregnancy is associated with abusive behavior by the mother towards infants at 4 months of age. A population-based sample of 6590 mothers with 4-month-old infants participated in this study in Japan. Abusive behavior was assessed via questionnaire and defined as frequency of shaking and smothering during the preceding month. Both verbal and physical IPV during pregnancy were assessed retrospectively. Multiple logistic regression analysis was used, adjusting for types of IPV and potential covariates, specifically postpartum depression. Maternal exposure to verbal and physical IPV during pregnancy was reported by 10.9% and 1.2% of women, respectively. In the adjusted model, women exposed to verbal IPV alone were significantly more likely to abuse offspring (odds ratio: 1.59, 95% confidence interval: 1.17-2.16) while exposure to physical IPV did not have an additive effect for abusive behavior. Maternal victimization by verbal, but not physical IPV was associated with maternal abusive behavior towards their 4-month-old infant. Screening for verbal abuse during pregnancy might be an efficient approach to identify high-risk mothers of infant abuse. PMID:27082752

    The objective was to identify maternal variables that could be used as predictors of the child's body mass index (BMI). We considered the following variables: (a) socio-demographic (age, education, occupation, marital status and family income); (b) anthropometric (BMI); and (c) upbringing strategies (monitoring and limits for eating habits, monitoring and sedentary behavior limits, discipline and control in feeding. A predictive correlational study was carried out with 537 dyads (mother-child). Children enrolled in 4 public schools (2 for pre-school children and 2 for primary school children) were selected for probabilistic, random sampling. The mothers answered the Feeding and Activity Upbringing Strategies Scale, giving socio-demographic information and the dyads' weight and height was measured. The data were analyzed for correlations and path analysis. It was found that the average age of mothers was 34.25 years (SD=6.91), with 12.40 years of education (SD=3.36), 53.3% mentioned that they were housewives and 46.7% had a paid job outside of the home; 38.5% showed pre-OB and 27.3% some degree of OB. The child's average age was 7.26 years (SD=2.46), and 3.2% showed low weight, 59.6% normal weight and 37.2% OW-0B. It was found that working outside the home, having a higher maternal BMI, less control and more discipline in feeding are variables that predict higher BMI in the child. We recommend the design of interventions to reduce and treat the child's OW-OB taking into account the predictors that were found. PMID:26821487

Also, pregnancy has been reported as the leading cause of death in adolescent girls in low- and middle-income countries. Aims: The aim of the study was to evaluate whether young maternal age was associated with an increased risk of obstetrics and perinatal adverse outcomes. Study Design: Case-control study. Methods: This case-control study was derived from a database of the medical records between January 2008 and December 2012. In the present study, 1374 teenage pregnancy and 1294 adult pregnancy cases were included. After restriction of analyses to singleton primiparous women, 1282 teenage pregnancy and 735 adult pregnancy cases were analyzed. Maternal age was separated into three groups: 15 and less, 16–19, and 20–34 years. Adjusted odds ratios (ORs) were derived through logistic regression models for the potential confounding factors. Results: Adolescents aged 15 years and younger had higher risks of preterm delivery, early preterm delivery, intrauterine fetal death and neonatal death compared with women aged 20 to 34 years after adjustment for confounding factors. In addition, both groups of adolescents had higher risks for anemia and episiotomy and lower risk of cesarean delivery. The rates of preeclampsia, gestational diabetes, chronic diseases, intrauterine growth restriction (IUGR) were higher in the adult group. Conclusion: Younger maternal age was correlated with increased risks of preterm delivery, fetal and neonatal death and anemia. PMID:27308080

    We examined the association of prenatal depressive symptoms at mid-pregnancy with child cognition at age 3 years in Project Viva, a pre-birth cohort study of 1030 mother-child pairs in eastern Massachusetts. We measured maternal depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS), a self-report measure validated for use during pregnancy. Measures of child cognition included the Peabody Picture Vocabulary Test (PPVT) and the Wide Range Achievement of Visual Motor Abilities (WRAVMA). At mid-pregnancy, 81 mothers (7.9%) scored 13 or above on the EPDS, indicating probable depression. In the unadjusted model, children born to mothers with prenatal depressive symptoms had PPVT scores that were 3.8 points lower [95% confidence interval (CI) -7.1, -0.5]. With adjustment for sociodemographic variables, the association substantially attenuated [adjusted regression coefficient b for PPVT score = -0.7 (95% CI -3.6, 2.3)]. In both unadjusted and multivariable models, prenatal depressive symptoms were not associated with WRAVMA scores [adjusted b for total WRAVMA score = -0.5 (95% CI -3.0, 2.1)]. We found no evidence to suggest that maternal prenatal depression is independently associated with early child cognition. PMID:20415752

    Low birth weight (LBW) babies (2500 gm or less at birth) are more likely to die and suffer sequelae. Intrauterine growth retardation (IUGR) babies also weight the same, but they are born at 37 weeks or over. Small for gestational age (SGA) is a related term used for babies weighing less than expected. 20.6 million LBW babies were born in 1979, most of then in developing countries. In the US, 12.1% of nonwhites vs. 6% of whites had LBW babies in 1980 (50% of infant deaths were attributed to LBWs). A study in Guatemala showed that LBWs accounted for 88% of neonatal deaths. 15-21% of the US decline in neonatal mortality since the 1960s was due to birth weight distribution. 50% of the decline in Alabama was attributable to improved obstetrical care from 1970 to 1980. 12,000 Finnish children were followed up for 14 years, and those born with weights below the mean had significantly higher mortality than normal weight children. The saving of very LBW babies by medical technology has raised ethical questions, as many have mental and physical retardation and the expenses are enormous. SGAs have smaller stature IUGR/low ponderal index infants had 2.9-5.7 times the mortality of full-term normal infants, and they also had poorer academic progress, but IUGR/adequate ponderal index babies fared even worse. Such afflictions carry across generations, as evidenced by a Seattle study on 748 white women indicating impaired reproductive performance of female infants. Some of the components producing LBW are: maternal genetic, social, cultural, and nutritional factors, smoking, and dieting during pregnancy, wars and famines (e.g., Leningrad and Wuppertal during and after World War II). Anthropometric studies indicate that mothers with greater body size have larger babies, but genetics also play a role here. Intervention studies confirmed the importance of nutrition: in a Mexican study and increase of 180 gm of birth weight and 29.6% reduction of LBW was produced by supplementation

    Objectives In light of the potential physical and emotional costs to both woman and child, this study was conducted to assess pregnancy complications and birth outcomes in primiparae at very advanced maternal age (VAMA, aged ≥45) compared to younger primiparae. Methods Retrospective cohort study comparing 222 VAMA primiparae and a reference group of 222 primiparae aged 30-35, delivering at Sheba Medical Center from 2008 through 2013.Results VAMA primiparae were more likely than younger primiparae to be single, to have chronic health conditions, and higher rates of gestational diabetes mellitus (GDM), gestational-hypertension (GHTN) and preeclampsia-eclampsia. VAMA primiparae conceived mostly by oocyte donation. They were more likely to be hospitalized during pregnancy, to deliver preterm and by cesarean birth. Infants of VAMA primiparae were at greater risk for low birthweight and Neonatal Intensive Care Unit admission. There were no differences in outcomes between VAMA primiparae with or without preexisting chronic conditions, or between those aged 45-49 and ≥50. In multivariable analysis VAMA was an independent risk factor for GDM, GHTN and preeclamsia-eclampsia, with adjusted odds ratio of 2.38 (95 % CI 1.32, 4.29), 5.80 (95 % CI 2.66, 12.64) and 2.45 (95 % CI 1.03, 5.85); respectively. The effect of age disappeared in multiple pregnancies. Conclusions Primiparity at VAMA holds a significant risk for adverse pregnancy and birth outcomes. The absence of chronic medical conditions or the use of a young oocyte donor does not improve these outcomes. Multiple pregnancies hold additional risk and may diminish the effect of age. Primiparity at an earlier age should be encouraged. PMID:26686195

    Advanced maternal age of first time pregnant mothers is associated with prolonged and dysfunctional labor and significant risk of emergency cesarean section. We investigated the influence of maternal age on myometrial contractility, expression of contractile associated proteins (CAPs), and global gene expression in the parturient uterus. Female Wistar rats either 8 (YOUNG n = 10) or 24 (OLDER n = 10) weeks old were fed laboratory chow, mated, and killed during parturition. Myometrial strips were dissected to determine contractile activity, cholesterol (CHOL) and triglycerides (TAG) content, protein expression of connexin-43 (GJA1), prostaglandin-endoperoxide synthase 2 (PTGS2), and caveolin 1 (CAV-1). Maternal plasma concentrations of prostaglandins PGE2, PGF2α, and progesterone were determined by RIA. Global gene expression in uterine samples was compared using Affymetrix Genechip Gene 2.0 ST arrays and Ingenuity Pathway analysis (IPA). Spontaneous contractility in myometrium exhibited by YOUNG rats was threefold greater than OLDER animals (P < 0.027) but maternal age had no significant effect on myometrial CAP expression, lipid profiles, or pregnancy-related hormones. OLDER myometrium increased contractile activity in response to PGF2α, phenylephrine, and carbachol, a response absent in YOUNG rats (all P < 0.002). Microarray analysis identified that maternal age affected expression of genes related to immune and inflammatory responses, lipid transport and metabolism, steroid metabolism, tissue remodeling, and smooth muscle contraction. In conclusion YOUNG laboring rat myometrium seems primed to contract maximally, whereas activity is blunted in OLDER animals and requires stimulation to meet contractile potential. Further work investigating maternal age effects on myometrial function is required with focus on lipid metabolism and inflammatory pathways. PMID:25876907

    Vertical transmission of Hepatitis B virus HBV can result in a state of chronic HBV infection and its complications. HBV vaccination with or without hepatitis B immunoglobulin (HBIG) prevents transmission of overt infection to the babies. However, whether it also prevents occult HBV infection in babies is not known. Consecutive pregnant women of any gestation found to be HBsAg positive were followed till delivery, and their babies were included in the study. Immediately after delivery, babies were randomized to receive either HBIG or placebo in addition to recombinant HBV vaccine (at 0, 6, 10 and 14 weeks). The primary end-point of the study, assessed at 18 weeks of age, was remaining free of any HBV infection (either overt or occult) plus the development of adequate immune response to vaccine. The babies were further followed up for a median of 2 years of age to determine their eventual outcome. Risk factors for HBV transmission and for poor immune response in babies were studied. Of the 283 eligible babies, 259 were included in the trial and randomized to receive either HBIG (n=128) or placebo (n=131) in addition to recombinant HBV vaccine. Of the 222 of 259 (86%) babies who completed 18 weeks of follow-up, only 62/222 (28%) reached primary end-point. Of the remaining, 6/222 (3%) developed overt HBV infection, 142/222 (64%) developed occult HBV infection, and 12/222 (5%) had no HBV infection but had poor immune response. All 6 overt infections occurred in the placebo group (P=0.030), while occult HBV infections were more common in the HBIG group (76/106 [72%] vs. 66/116 [57%]; P=0.025). This may be due to the immune pressure of HBIG. There was no significant difference between the two groups in frequency of babies developing poor immune response or those achieving primary end-point. The final outcome of these babies at 24 months of age was as follows: overt HBV infection 4%, occult HBV infection 42%, no HBV infection but poor immune response 8% and no HBV

    Background Age of puberty has declined substantially in developed settings and is now declining in the rest of the world with economic development. Early age of puberty is associated with non-communicable diseases in adulthood, and may be a long-term driver of population health with effects over generations. In a non-Western setting, we examined the association of maternal age of menarche with blood pressure in late childhood/adolescence. Methods We used generalised estimating equations to estimate the adjusted association of maternal age of menarche with age-, sex- and height-adjusted blood pressure z-score from 10 to 16 years in Hong Kong’s population-representative birth cohort, “Children of 1997” (n = 8327). We also assessed whether associations were mediated by body mass index (BMI) or pubertal stage. Results Earlier maternal age of menarche was associated with higher systolic blood pressure in adolescence [-0.02 z-score per year older maternal age of menarche, 95% confidence interval (CI) -0.04 to -0.003]. The association of maternal age of menarche with systolic blood pressure was mediated by adiposity and/or pubertal stage at 11 years. Maternal age of menarche was not associated with diastolic blood pressure. Conclusion Earlier maternal age of puberty was associated with higher systolic blood pressure, largely mediated by adiposity, highlighting the importance of tackling childhood obesity as a public health priority in view of the secular trend of declining age of puberty.

    The development and life performance of 404 high-producing Holstein dairy cows was studied from birth onwards and during two lactations. The management, environment and parental genetics of the cows were known in detail. Cluster analysis identified four performance 'types': high-yielding (HY) cows and persistently high-yielding (PHY) cows, which accounted for 33% of the animals; medium-yielding (MY) cows, 41%; and low-yielding (LY) cows, 26%. Prenatal determinants of the life performance of the progeny were analyzed. Developmental and environmental factors were excluded as determinants of performance (including birth weight, level of passive immunity transfer, growth rate, age at first parturition and reproductive efficiency). Life performance did show minor seasonal effects, with more HY cows but less PHY being born during the cold season (90.1% in HY; 58.3% in PHY v. 81.5%). Instead, the single most important factor influencing life performance of daughters was maternal age. HY cows were born from the youngest mothers (1.89±1.14 parturitions, 3.12±1.42-year old), whereas LY cows were born from the oldest (2.72±1.80 parturitions, 3.97±2.01-year old; P<0.001). Life performance of the dams did not differ among clusters. In addition, metabolic parameters (fat and protein yield) were found to correlate significantly with yields between the first and second lactations (milk yield: r=0.357; fat yield: r=0.211; protein yield: r=0.277; P<0.0001), suggesting the influence of the individual. These results suggest that under optimal health, nutritional and environmental conditions, maternal aging is an important determinant of the life performance of progeny and argue for the need to identify conditions that contribute to health and disease in progeny according to the Developmental Origin of Health and Disease or DOHaD concept. Our findings may help the development of novel management guidelines for dairy farms. PMID:25084160

    Amniocentesis is an invasive procedure performed during pregnancy to determine, among other things, whether the fetus has Down syndrome. It is often preceded by screening, which gives a probabilistic risk assessment. Thus, ample information is conveyed to women with the goal to inform their decisions. This study examined the factors that predict amniocentesis uptake among pregnant women of advanced maternal age (older than 35 years old at the time of childbirth). Participants filled out a questionnaire regarding risk estimates, demographics, and attitudes on screening and pregnancy termination before their first genetic counseling appointment and were followed up to 24 weeks of gestation. Findings show that women's decisions are not always informed by screening results or having a medical indication. Psychological factors measured at the beginning of pregnancy: amniocentesis risk tolerance, pregnancy termination tolerance, and age risk perception affected amniocentesis uptake. Although most women thought that screening for Down syndrome risk would inform their decision, they later stated other reasons for screening, such as preparing for the possibility of a child with special needs. Findings suggest that women's decisions regarding amniocentesis are driven not only by medical factors, but also by a priori attitudes. The authors believe that these should be addressed in the dialogue on women's informed use of prenatal tests. PMID:26065331

  15. Maternal age and spine development in a rotifer: ecological implications and evolution.

    2013-10-01

    Brachionus calyciflorus typically develops long, defensive spines only in response to a kairomone from the predatory rotifer, Asplanchna. However, in the absence of any environmental induction, females of some clones produce daughters with increasingly long spines as they age; late-born individuals can have posterolateral spines as long as those induced by Asplanchna: up to 50% or more of body length. Here, we construct a model using data from life-table and predator-prey experiments to assess how this maternal-age effect can influence the distribution of spine lengths in reproducing populations and provide defense against Asplanchna predation. When Asplanchna is absent, the frequency of individuals with late birth orders rapidly becomes extremely low; thus, any cost associated with the production of long-spined individuals is minimal. When Asplanchna is present at densities too low for spine induction, and preys selectively on individuals with no or short posterolateral spines, the frequency of long-spined individuals rapidly increases until a stable birth-order structure is reached. As a result, mortality from Asplanchna predation is greatly reduced. The pronounced and novel birth-order effect in this rotifer appears to be an effective bet-hedging strategy to limit predation by Asplanchna when its kairomone induces no or less than maximal spine development.

    Objective: Nutrition in childhood has an important role in current and adulthood health. Recent studies have shown that the mother’s lifestyle has an important role in the methods used by mother to feed child. This paper aimed to investigate the association between mother’s weight efficacy lifestyle with feeding practices in children aged 3- 6 years. Materials and Methods: In this cross-sectional study which was carried out in 30 primary schools of Rasht (Iran) in 2012, 165 mothers with children aged 3-6 years were participated. Mothers reported their own and their child’s demographics. Aspects of mother’s weight efficacy lifestyle and mother’s control practices were assessed using Weight Efficacy Lifestyle (WEL) questionnaire and Comprehensive Feeding Practices questionnaire (CFPQ) respectively. Height and weight of mothers participated in the study were measured. The role of mother’s weight efficacy in predicting child’s feeding practices was assessed using linear regression. Results: Results showed that mother’s weight efficacy was related to child feeding practices. The mothers with similar weight efficacy lifestyle applied similar methods in child nutrition. Mothers with better weight efficacy used more encourage balance and variety, environmental control, child involvement and less emotion regulation using foods. Conclusion: ‎ ‏ ‏‎ The result of the ‎study showed that maternal ‎lifestyle was associated with ‎child feeding practices.‎ PMID:27006673

    380 women of parity 1 or more living in coffee plantations of the Pacific lowlands of Guatemala were studied during the 18-month period from October 1977 to March 1979 to investigate the relationship between maternal stature, parity, offspring mortality, and number of surviving children. Average height was 142 cm or 4 feet 8 inches, average age was 28 years, and average parity was 4.4 children per woman: average number of surviving children per woman was 3. Simple correlation analysis shows that although shorter women appeared to have greater parities but fewer surviving children, the relationships were not statistically significant (p.05). However, when age and/or parity were adjusted, the association between maternal stature and number of surviving children became statistically significant (p.05). Children of shorter mothers exhibited high mortality rates which were not affected by adjustments for maternal age and parity (p.001). A possible explanation of the link between maternal stature and offspring survival is that taller women generally have heavier babies. This study suggests that maternal height can be used to identify infants at high mortality risk; this can have potential use in developing nations where many women do not get examined more than once during pregnancy.

    Maternal depression and anxiety represent risk factors for the quality of early mother-preterm infant interactions, especially in the case of preterm birth. Despite the presence of many studies on this topic, the comorbidity of depressive and anxious symptoms has not been sufficiently investigated, as well as their relationship with the severity of prematurity and the quality of early interactions. The Aim of this study was to evaluate the quality of early mother-infant interactions and the prevalence of maternal depression and anxiety comparing dyads of extremely low birth weight (ELBW) and very low birth weight (VLBW) preterm infants with full-term ones. Seventy seven preterm infants (32 ELBW; 45 VLBW) and 120 full term (FT) infants and their mothers were recruited. At 3 months of corrected age, 5 min of mother-infant interactions were recorded and later coded through the Global Ratings Scales. Mothers completed the Edinburgh Postnatal Depression Scale and Penn State Worry Questionnaire. Infant levels of development were assessed through the Griffiths Mental Development Scales. A relation emerged among the severity of prematurity, depression, anxiety, and the quality of interactions. When compared with the FT group, the ELBW interactions were characterized by high maternal intrusiveness and low remoteness, while the VLBW dyads showed high levels of maternal sensitivity and infant communication. Depression was related to maternal remoteness and negative affective state, anxiety to low sensitivity, while infant interactive behaviors were impaired only in case of comorbidity. ELBW’s mothers showed the highest prevalence of depressive and anxious symptoms; moreover, only in FT dyads, low maternal sensitivity, negative affective state and minor infant communication were associated to the presence of anxious symptoms. The results confirmed the impact of prematurity on mother–infant interactions and on maternal affective state. Early diagnosis can help to plan

    This study leveraged data from the Minnesota Longitudinal Study of Risk and Adaptation (N = 243) to investigate the predictive significance of maternal sensitivity during the first 3 years of life for social and academic competence through age 32 years. Structural model comparisons replicated previous findings that early maternal sensitivity predicts social skills and academic achievement through midadolescence in a manner consistent with an enduring effects model of development and extended these findings using heterotypic indicators of social competence (effectiveness of romantic engagement) and academic competence (educational attainment) during adulthood. Although early socioeconomic factors and child gender accounted for the predictive significance of maternal sensitivity for social competence, covariates did not fully account for associations between early sensitivity and academic outcomes.

    Maternal inflammation during pregnancy can elevate the risk of neurodegenerative disorders in offspring. However, how it affects age-related impairments of spatial learning and memory and changes in the neurobiological indictors in the offspring in later adulthood is still elusive. In this study, the CD-1 mice with maternal gestational inflammation due to receiving lipopolysaccharide (LPS, i.p. 50 or 25μg/kg) were divided into 3-, 12-, 18-, and 22-month-old groups. The spatial learning and memory were evaluated using a six-radial arm water maze and the levels of presynaptic proteins (synaptotagmin-1 and syntaxin-1) and histone acetylation (H3K9ac and H4K8ac) in the dorsal hippocampus were detected using the immunohistochemical method. The results indicated that there were significant age-related impairments of spatial learning and memory, decreased levels of H4K8ac, H3K9ac, and syntaxin-1, and increased levels of synaptotagmin-1 in the offspring mice from 12 months old to 22 months old compared to the same-age controls. Maternal LPS treatment significantly exacerbated the offspring impairments of spatial learning and memory, the reduction of H3K9ac, H4K8ac, and syntaxin-1, and the increment of synaptotagmin-1 from 12 months old to 22 months old compared to the same-age control groups. The changes in the neurobiological indicators significantly correlated with the impairments of spatial learning and memory. Furthermore, this correlation, besides the age and LPS-treatment effects, also showed a dose-dependent effect. Our results suggest that maternal inflammation during pregnancy could exacerbate age-related impairments of spatial learning and memory, and neurobiochemical indicators in the offspring CD-1 mice from midlife to senectitude.

    Objective Early parenting experiences likely shape children’s brain development, with consequences potentially extending into adulthood. Parents’ affective disorders and expressions of positive affect could exert an influence on affect-related circuitry. The current study evaluated how maternal depression and maternal warmth assessed in early childhood and early adolescence were related to boys’ reward function during early adulthood. Method Participants were 120 boys at socioeconomic risk for emotional problems. Mothers’ history of depression during the child’s lifetime was measured when boys were 42 months old and 10/11 years old. Maternal warmth was observed during mother–child interactions at 18 and 24 months and at 10 and 11 years. Results Maternal warmth during early childhood was associated with less activation in the medial prefrontal cortex (mPFC) when anticipating and experiencing reward loss. Maternal warmth during early adolescence was associated with less activation in the mPFC when winning rewards and greater activation in the caudate when experiencing loss. The association between maternal warmth during early childhood and early adolescence and reward function in the striatum and mPFC was stronger for boys exposed to maternal depression relative to boys who were not. Conclusions The experience of warmth and affection from mothers may be a protective factor for reward function in boys exposed to maternal depression, possibly by engaging vulnerable neural reward systems through affiliation.

    Aims The developmental origins of health and disease hypothesis states that later-life disease may be influenced by the quality of the in utero environment. Environmental toxicants can have detrimental effects on fetal development, potentially through effects on placental development and function. Maternal smoking during pregnancy is associated with low birth weight, preterm birth and other complications, and exposure to cigarette smoke in utero has been linked to gross pathologic and molecular changes to the placenta, including differential DNA methylation in placental tissue. The aim of this study was to investigate the relationship between maternal smoking during pregnancy, methylation changes in the placenta and gestational age. Materials & methods We used Illumina®’s (CA, USA) Human Methylation27 BeadChip technology platform to investigate the methylation status of 21,551 autosomal, non-SNP-associated CpG loci in DNA extracted from 206 human placentas and examined loci whose variation in methylation was associated with maternal smoking during pregnancy. Results We found that methylation patterns of a number of loci within the RUNX3 gene were significantly associated with smoking during pregnancy, and one of these loci was associated with decreased gestational age (p = 0.04). Conclusion Our findings, demonstrating maternal smoking-induced changes in DNA methylation at specific loci, suggest a mechanism by which in utero tobacco smoke exposure could exert its detrimental effects upon the health of the fetus.

    To study the association of advanced maternal age (AMA) and race/ethnicity on placental pathology in very low birthweight (VLBW) infants. Retrospective analysis of placental pathology of inborn singleton VLBW infants from a regional level 3 NICU between July, 2002 and June, 2009. Subjects were stratified by age and race/ethnicity. Statistical analysis included One-way ANOVA, Chi Square and multivariable analyses. A total of 739 mother/infant dyads were included. AMA was associated with a decrease in placental weight and placental weight/birthweight ratio. Black/Non-Hispanic mothers ≥35 had a lower placental weight (p = 0.01) and lower placental weight/birth weight ratio (z-score, -0.45 ± 0.71 vs -0.04 ± 1.1, p = 0.01) compared to Black/Non-Hispanic mothers <35 years of age. After controlling for gestational age, race/ethnicity, maternal diabetes, maternal smoking, maternal hypertension and clinical chorioamnionitis, AMA, but not race/ethnicity, remained independently associated with placental weight/birthweight ratio z score (full model r(2) = 0.22, p < 0.01). In our study sample of VLBW infants, placental weight and placental weight/birthweight ratio were lower in mothers of advanced maternal age compared to mothers <35 years of age. Our data suggest that maternal age affects placentation in VLBW infants, which could influence maternal and neonatal outcomes. PMID:25567078

    Objective Phthalates and bisphenol A (BPA) are ubiquitous environmental toxicants, present in high concentrations in numerous consumer products. We hypothesized that maternal exposure to phthalates and BPA in pregnancy is associated with shortened gestation. Methods Urinary phthalate and BPA metabolites from 72 pregnant women were measured at the last obstetric clinic visit prior to delivery. Using linear regression models, we estimated the change in gestational age associated with each interquartile range (IQR) increase in phthalate and BPA metabolite concentration. Results IQR increases in urinary mono(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and BPA concentrations were associated with 4.2 and 1.1 day decreases in gestation, respectively. When stratified by gender, these alterations were found only in male infants. Conclusions We conclude that MEHHP and BPA (free + glucuronide) are associated with reductions in gestation, with effects observed only in males. Our findings are consistent with the idea that these agents induce gender-specific alterations in signaling via PPAR-γ transcription factor, androgen precursors, and/or inflammatory mediators during the initiation of labor.

  18. The association between advanced maternal and paternal ages and increased adult mortality is explained by early parental loss

    PubMed Central

    Elo, Irma T.; Kohler, Iliana; Martikainen, Pekka

    2015-01-01

    The association between advanced maternal and paternal ages at birth and increased mortality among adult offspring is often attributed to parental reproductive ageing, e.g., declining oocyte or sperm quality. Less attention has been paid to alternative mechanisms, including parental socio-demographic characteristics or the timing of parental death. Moreover, it is not known if the parental age-adult mortality association is mediated by socioeconomic attainment of the children, or if it varies over the lifecourse of the adult children. We used register-based data drawn from the Finnish 1950 census (sample size 89,737; mortality follow-up 1971–2008) and discrete-time survival regression with logit link to analyze these alternative mechanisms in the parental age-offspring mortality association when the children were aged 35–49 and 50–72. Consistent with prior literature, we found that adult children of older parents had increased mortality relative to adults whose parents were aged 25–29 at the time of birth. For example, maternal and paternal ages 40–49 were associated with mortality odds ratios (ORs)of 1.31 (p<.001) and 1.22 (p<.01), respectively, for offspring mortality at ages 35–49. At ages 50–72 advanced parental age also predicted higher mortality, though not as strongly. Adjustment for parental socio-demographic characteristics (education, occupation, family size, household crowding, language) weakened the associations only slightly. Adjustment for parental survival, measured by whether the parents were alive when the child reached age 35, reduced the advanced parental age coefficients substantially and to statistically insignificant levels. These results indicate that the mechanism behind the advanced parental age-adult offspring mortality association is mainly social, reflecting early parental loss and parental characteristics, rather than physiological mechanisms reflecting reproductive ageing.

    Background Intracytoplasmic sperm injection (ICSI) was considered as the mainstay of treatment for male infertility. Nowadays, the scope of ICSI has been widened to include other causes of infertility. There are few published data on ICSI in countries with low incomes. Aims A cross-sectional study was conducted at Saad AbuAlla and Banoun Centers, Khartoum, Sudan to investigate outcomes of ICSI and to determine the parameters that might predict pregnancy success rate following ICSI. Methods The study included 191 infertile couples who underwent 296 ICSI cycles between 1st April 2013 and 31 March 2014. Results One hundred and ninety one couples (comprising 296 cycles of ICSI) were enrolled to the study. The mean (SD) number of retrieved oocytes was 9.7 (7.5).  The mean (SD) number of transferred embryos was 2.9 (1.0). Out of these, 50 (26.2%) and 40 (20.9%) had chemical and clinical pregnancy, respectively. Thirty–six couples (18.8%) and five couples (2.6%) had miscarriage and had ectopic pregnancy, respectively. Under logistic regression, younger age (OR = 0.8, 95% CI= 0.81 ─ 0.96, P = 0.004) and endometrial thickness (OR = 1.3, 95% CI= 1.07─1.60, P = 0.009) were the significant predictors for the success of ICSI in inducing pregnancy. Conclusion                 The rates of successful fertilisation and pregnancy-to-term rates in this setting depend mainly on the maternal age. PMID:27347370

    The manifestation of mitochondrial DNA (mtDNA) diseases depends on the frequency of heteroplasmy (the presence of several alleles in an individual), yet its transmission across generations cannot be readily predicted owing to a lack of data on the size of the mtDNA bottleneck during oogenesis. For deleterious heteroplasmies, a severe bottleneck may abruptly transform a benign (low) frequency in a mother into a disease-causing (high) frequency in her child. Here we present a high-resolution study of heteroplasmy transmission conducted on blood and buccal mtDNA of 39 healthy mother-child pairs of European ancestry (a total of 156 samples, each sequenced at ∼20,000× per site). On average, each individual carried one heteroplasmy, and one in eight individuals carried a disease-associated heteroplasmy, with minor allele frequency ≥1%. We observed frequent drastic heteroplasmy frequency shifts between generations and estimated the effective size of the germ-line mtDNA bottleneck at only ∼30-35 (interquartile range from 9 to 141). Accounting for heteroplasmies, we estimated the mtDNA germ-line mutation rate at 1.3 × 10(-8) (interquartile range from 4.2 × 10(-9) to 4.1 × 10(-8)) mutations per site per year, an order of magnitude higher than for nuclear DNA. Notably, we found a positive association between the number of heteroplasmies in a child and maternal age at fertilization, likely attributable to oocyte aging. This study also took advantage of droplet digital PCR (ddPCR) to validate heteroplasmies and confirm a de novo mutation. Our results can be used to predict the transmission of disease-causing mtDNA variants and illuminate evolutionary dynamics of the mitochondrial genome. PMID:25313049

    Gestational diabetes mellitus is a major complication of human pregnancy. The oral clearance (CL) of glyburide, an oral antidiabetic drug, increases 2-fold in pregnant women during late gestation versus nonpregnant controls. In this study, we examined gestational age–dependent changes in maternal-fetal pharmacokinetics (PK) of glyburide and metabolites in a pregnant mouse model. Nonpregnant and pregnant FVB mice were given glyburide by retro-orbital injection. Maternal plasma was collected over 240 minutes on gestation days (gd) 0, 7.5, 10, 15, and 19; fetuses were collected on gd 15 and 19. Glyburide and metabolites were quantified using high-performance liquid chromatography–mass spectrometry, and PK analyses were performed using a pooled data bootstrap approach. Maternal CL of glyburide increased approximately 2-fold on gd 10, 15, and 19 compared with nonpregnant controls. Intrinsic CL of glyburide in maternal liver microsomes also increased as gestation progressed. Maternal metabolite/glyburide area under the curve ratios were generally unchanged or slightly decreased throughout gestation. Total fetal exposure to glyburide was <5% of maternal plasma exposure, and was doubled on gd 19 versus gd 15. Fetal metabolite concentrations were below the limit of assay detection. This is the first evidence of gestational age–dependent changes in glyburide PK. Increased maternal glyburide clearance during gestation is attributable to increased hepatic metabolism. Metabolite elimination may also increase during pregnancy. In the mouse model, fetal exposure to glyburide is gestational age–dependent and low compared with maternal plasma exposure. These results indicate that maternal glyburide therapeutic strategies may require adjustments in a gestational age–dependent manner if these same changes occur in humans. PMID:24898265

    Filicide occurs in every socioeconomic stratum around the world. This study was conducted to evaluate motives, psychopathological aspects, and socio-demographic factors of 74 filicide cases of women in Turkey. Mean age of mothers, most of whom committed infanticide, was 26 years, and breakdown of criminal offenses are as follows: "to get rid of unwanted babies" (24.3%), "acute psychotic-type filicide" (21.6%), "fatal child abuse and neglect" (17.6%), "to get revenge" (12.2%), "protect the lonely child from the harm and badness after suicide" (10.8%), and "pity" (9.5%) motives. Results showed that maternal filicide cannot be reduced to only mental instability or environmental factors and indicates deficiencies in the capacity of the mothers' role in connecting with their child and with parenting skills. Finally, with regard to defendants' motives, similar factors that contribute to committing maternal filicide should be considered while making an assessment of the data and determining employee risk groups.

    Newborn mammals are highly susceptible to respiratory infections. Although maternal antibodies (MatAb) offer them some protection, they may also interfere with their systemic immune response to vaccination. However, the impact of MatAb on the neonatal mucosal immune response remains incompletely described. This study was performed to determine the effect of ovalbumin (OVA)-specific MatAb on the anti-OVA antibody response in sera, nasal secretions and saliva from specific pathogen-free Vietnamese miniature piglets immunized at 7 or 14 days of age. Our results demonstrated that MatAb increased antigen-specific IgA and IgG responses in sera, and transiently enhanced an early secretory IgA response in nasal secretions of piglets immunized at 7 days of age. In contrast, we detected a lower mucosal (nasal secretion and saliva) anti-OVA IgG response in piglets with MatAb immunized at 14 days of age, compared with piglets with no MatAb, suggesting a modulatory effect of antigen-specific maternal factors on the isotype transfer to the mucosal immune exclusion system. In our porcine model, we demonstrated that passive maternal immunity positively modulated the systemic and nasal immune responses of animals immunized early in life. Our results, therefore, open the possibility of inducing systemic and respiratory mucosal immunity in the presence of MatAb through early vaccination. PMID:24754050

    Atopic eczema is most commonly diagnosed in children under the age of 5 yr. Environmental factors during pregnancy or in early life may confer risk for childhood atopic eczema. The present prospective study examined the relationship of the perinatal home environment and the risk of suspected atopic eczema among Japanese infants under the age of 1. Study subjects were 865 parent-child pairs. The term 'suspected atopic eczema' was used to define an outcome based on our questionnaire at 2-9 months postpartum. Adjustment was made for maternal age, gestation, family income, maternal and paternal education, maternal and paternal history of asthma, atopic eczema, and allergic rhinitis, time of delivery before the second survey, baby's older siblings, baby's sex, and baby's birth weight. A high mite allergen level from maternal bedclothes and mold in the kitchen during pregnancy were significantly associated with an increased risk of suspected atopic eczema. Frequent vacuuming practices during pregnancy and giving the infant a bath or shower at least once a day were significantly inversely related to the risk of suspected atopic eczema. Maternal smoking, maternal use of a synthetic duvet and pillow, carpet use in the living room and maternal bedroom, indoor domestic pets, no ducted heating appliance, and gas use for cooking during pregnancy and household smoking in the same room as the infant, infant's synthetic duvet, carpet use in the infant's room, or vacuuming the infant's room were not related to the risk of suspected atopic eczema. High house dust mite allergen levels and mold in the kitchen during pregnancy may increase the risk of infantile atopic eczema, whereas frequent vacuuming practices during pregnancy and giving the infant a bath or shower at least once a day may protect against infantile atopic eczema.

    Objectives To examine the association between maternal relationship status during pregnancy and infant birth outcomes. Methods Observational study of the National Longitudinal Survey of Youth 1979, a nationally representative sample of 12,686 men and women between the ages of 14 and 21. We used data from surveys of women reporting childbirth between 1979 and 2004. Relationship status was defined as relationship with an opposite-sex partner in the child's birth year. Relationship stability was defined as the consistency in relationship status in the 1 year before, of, and after the child's birth. Childbirth outcome included small-for-gestational age (SGA) infant. We applied random effects logistic regression models to assess the association between relationship status and stability and childbirth outcome-adjusting for maternal race, infant sex, history of miscarriage, employment, maternal age, multiparity, cohort-entry year, household poverty status, and tobacco use. Results The study included 4439 women with 8348 live births. In fully adjusted models, term SGA infants were more commonly born to partnered women (AOR 1.81; 95 % CI 1.20-2.73) and unmarried women (AOR 1.82; CI 1.34-2.47; LRT p value 0.0001), compared to married women. SGA infants were also more commonly born in unstable relationships (AOR 1.72; 95 % CI 1.14-2.63; LRT p value 0.01) compared to stable relationships. Conclusions for Practice Maternal relationship status and stability during pregnancy is independently associated with risk of SGA infant birth. PMID:27007984

    Background Previous studies have reported on adverse neonatal outcomes associated with parity and maternal age. Many of these studies have relied on cross-sectional data, from which drawing causal inference is complex. We explore the associations between parity/maternal age and adverse neonatal outcomes using data from cohort studies conducted in low- and middle-income countries (LMIC). Methods Data from 14 cohort studies were included. Parity (nulliparous, parity 1-2, parity ≥3) and maternal age (<18 years, 18-<35 years, ≥35 years) categories were matched with each other to create exposure categories, with those who are parity 1-2 and age 18-<35 years as the reference. Outcomes included small-for-gestational-age (SGA), preterm, neonatal and infant mortality. Adjusted odds ratios (aOR) were calculated per study and meta-analyzed. Results Nulliparous, age <18 year women, compared with women who were parity 1-2 and age 18-<35 years had the highest odds of SGA (pooled adjusted OR: 1.80), preterm (pooled aOR: 1.52), neonatal mortality (pooled aOR: 2.07), and infant mortality (pooled aOR: 1.49). Increased odds were also noted for SGA and neonatal mortality for nulliparous/age 18-<35 years, preterm, neonatal, and infant mortality for parity ≥3/age 18-<35 years, and preterm and neonatal mortality for parity ≥3/≥35 years. Conclusions Nulliparous women <18 years of age have the highest odds of adverse neonatal outcomes. Family planning has traditionally been the least successful in addressing young age as a risk factor; a renewed focus must be placed on finding effective interventions that delay age at first birth. Higher odds of adverse outcomes are also seen among parity ≥3 / age ≥35 mothers, suggesting that reproductive health interventions need to address the entirety of a woman’s reproductive period.

    Aim: The aim of this study was to evaluate physical growth of very low birth weight (VLBW) preterm babies at a mean age of three years and to investigate the factors which affected growth. Material and Methods: The factors including maternal problems, prenatal problems, early neonatal problems, nutrition, familial socioeconomical status and presence of chronic disease which affected catch-up growth in terms of height and weight in VLBW infants followed up in the neonatal intensive care unit (NICU) of our hospital were examined. The target height formula was used in assessment of growht in height and the contribution of genetic properties was investigated. The points of the subjects on the growth curve were plotted according to the Percentile Curve of the Turkish Children prepared by Neyzi et al. The states of the subjects with and without intrauterine growth retardation (were compared. The study was intitiated after obtaining approval from the ethics committeee of our hospital (100/25.10.2005). Results: One hundred and seventeen preterm babies (57 females and 60 males) with a mean adjusted age of 35.8±2.39 80 of whom were appropriate for gestational age (AGA), 28 of whom were symmetrical (small gestational age) SGA and 9 of whom were asymmetrical SGA were included in the study. The mean gestational age (GA) was found to be 31±2.16 weeks and the mean birth weight (BW) was found to be 1271±226 g. The mean current height was found to be 92.06±4.90 cm. The mean weight was found to be 12.98±1.94 kg. The mean target height was calculated to be 163.66±8.1 cm (157.20 cm for the girls and 170.20 cm for the boys). It was found that 15 preterm babies (12.8%) could not achieve the target height (girls: 6%, boys: 6.8%). The risk factors related with failure to achieve target height were found to include ventilator treatment, presence of chronic disease, advanced stage intracranial bleeding (ICB), posthemorrhagic hydrocephalus, absence of breastfeeding, failure to sit at

In 1971, to avoid a projected population of 2.4 billion by 2050, Chinese leaders launched the "later-longer-fewer" campaign. Men and women were encouraged to postpone marriage until their mid- to late-20s, to allow 4 years between pregnancies, and to limit their families to 2 children. The standards were slightly more lenient in the rural areas. Together, the campaign was responsible for a reduction in the total fertility rate from 5.9 births/woman in 1970 to 2.7 births in 1979. Yet, due to the age structure of the population, with 39% of Chinese under age 15, even replacement-level fertility was bound to generate growth for decades. Consequently, in 1979, the post-Mao leadership inaugurated the "1-child" policy, a program designed to limit the Chinese population to 1.2 billion by 2000. Family planning has become a state sanctioned and monitored activity. The policy is implemented via public education, persuasion, peer pressure, and a series of incentives and penalties. In this context, the question arises as to what caused China's birthrate to rise. A major factor is the effect of the country's youth-dominated age structure. Following the Great Leap Forward (1958-60) and the prolonged accompanying famine, the birthrate increased markedly as couples conceived the children they had postponed. These baby boomers, born from 1962-64, now are having their own babies. About 1/3 of the 1986 increase in births may be accounted for by the ripple effect of this relatively large cohort finally reaching reproductive age. Further, the age of 1st reproduction has declined recently in response to the Marriage Law of 1980, which lowers the legal marriage age. Another influence has been a gradual yet significant relaxation in some of the basic tenets of the 1-child policy. In 1984, the government reaffirmed the critical importance of family planning but increased

    Scientific reports suggest that the exposure to long-term stressors throughout or during late gestation increase anxiety- and depression-like behaviors of offspring in their later life. Moreover, several studies concluded that increasing age correlates with increased anxiety behaviors in humans and rodents. In the present study, we assessed the effects of prenatally administration of equal lipopolysaccharide (LPS) doses in various points of late gestation (days 15, 16, and 17) period, on neuroendocrine and immunological responses of pregnant mice, and subsequent long-lasting consequences of anxiety and depression with increasing age in male offspring at postnatal days (PD) 40 and 80. Four hours after the LPS injection, levels of corticosterone (COR) and pro-inflammatory cytokines (PIC) in pregnant mice, as compared to the control dams, were increased significantly. Furthermore, maternal inflammation raised the levels of COR, anxiety- and depression-like behaviors with increasing age in male offspring in comparison with saline male offspring. These data support other studies demonstrating that maternal stress increases the levels of anxiety and depression in offspring. Additionally, our data confirm other findings indicating that increasing age correlates with increased anxiety or depression behaviors in humans and rodents. Findings of this study suggest that time course of an inflammation response or stressor application during various stages of gestation and ages of offspring are important factors for assessing neuropsychiatric disorders.

    Although caffeine is commonly consumed during pregnancy, there are few reports on the association of in utero caffeine exposure with offspring cognition or behavior during childhood. We evaluated the association of maternal serum paraxanthine, caffeine's primary metabolite, at <20 and ≥26 weeks' gestation with the child's intelligence quotient (IQ) and problem behaviors at ages 4 and 7 years among 2,197 mother-child pairs. The mothers were controls from a case-control study of caffeine metabolites and spontaneous abortion that was nested within the Collaborative Perinatal Project (multiple US sites, 1959-1974). Associations of paraxanthine (adjusted for maternal age, race, education, smoking, prepregnancy weight, gestational age at blood draw, and child sex) with mean IQ were assessed by linear regression and associations with problem behaviors by logistic regression. Paraxanthine concentration at ≥26 weeks' gestation manifested an inverted-J-shaped association with child's IQ at age 7 years, with a peak difference (vs. undetectable) of 0.65 points at 750 µg/L (66th percentile) and a decrement thereafter. Paraxanthine at <20 weeks was linearly associated with internalizing behavior at age 4 years (for a 500-µg/L increase, odds ratio = 1.3, 95% confidence interval: 1.1, 1.5). None of the remaining 12 associations approached statistical significance. We conclude that over a range of values applicable to most pregnant women, there was no meaningful association of serum paraxanthine level with childhood IQ or problem behaviors. PMID:26585526

    The present study aimed to (a) characterize the personal competencies, the social resources, and the psychosocial adjustment (psychological distress, quality of life, and parenting self-perceptions) during the early postpartum period of primiparous women of advanced age (≥35 years at the time of delivery) and their partners (older parents) compared with that of younger first-time mothers (20-34 years) and their partners (younger parents); and (b) explore the role of personal competencies and social resources in couples' psychosocial adjustment, depending on the age group. Older (n = 74) and younger parents (n = 71) completed self-report measures to assess personal competencies and social resources (third trimester of pregnancy), psychological distress, and quality of life (third trimester of pregnancy and 1-month' postpartum) and parenting self-perceptions (1-month' postpartum). Older parents were more similar than different from younger parents regarding personal competencies, social resources, and psychosocial adjustment during the first postnatal month. Regardless of the age group, higher personal competencies and social resources predicted lower anxiety and more positive parenting self-perceptions in women. Beyond higher personal competencies, older maternal age also predicted higher quality of life. In men, higher personal competencies were protective against anxiety, but only at older maternal age.

    In India, a simple scoring method was used to select winners at 18 well-baby shows over the last five years in low-income areas of Kotla Mubarakpur and Gautam Nagar, in the Rajeev Gandhi Resettlement Colony, in jhuggi jhopri clusters around the All Institute of Medical Sciences (AAIMS) in New Delhi, and in the Bangladeshi refugee colony (Kidwai Nagar). The parameters used to select ideal babies were parents' age at marriage and educational status, mother's age at first birth, number of living children in relation to marriage duration, immunization status of living children, birth interval, contraceptive use, and routine criteria on general health and hygiene. Winners were chosen among infants, toddlers (1-2 years), and preschool children (2-5). Health promotional activities, maternal and child health (MCH) services, and family planning (FP) services were featured at the health camps where the well-baby shows occurred. 60-90 children and 100-2000 couples participated in the well-baby shows. Health workers explained to parents of children with a poor score why their children had a poor score. At the health camps, parents adopted FP methods and had their children immunized, regardless of score, so as to improve their score for the next show and to win prizes. The well-baby scores improved over time (24.64-31.2 for Kotla Mubarakpur, 19-24.6 for Gautam Nagar, 20.9-22.4 for Rajeev Gandhi, 20.6-23.6 for AIIMS jhuggi, and 13.6-21.4 for Kidwai Nagar). A weekly clinic operating in Kotla Mubarakpur accounted for the high initial mean score. Gautam Nagar had only periodic health services. A weekly mobile health van provided services in the Rajeev Gandhi colony. Door to door contacts were conducted in the jhuggi jhopri clusters to promote MCH/FP services. The scoring method reinforced integration of MCH/FP services. It allowed local health workers to make rapid analyses and MCH decision making. It also served as a tool to monitor the efficacy of local MCH/FP services. PMID

    The aim of this study is to analyse the impact of maternal age at first birth on low birth weight, preterm birth and low Apgar scores at one minute and at five minutes among live births delivered to primiparous Brazilian women in the city of São Paulo. Analyses were based on 73,820 birth records from the 1998 birth cohort. Logistic regression was used to assess the association between maternal age and each outcome variable, controlling for the following risk factors: delivery mode, plurality, sex, maternal education, number of prior losses, prenatal care, race, parity and community development. Maternal ages below 20 and above 30 years were significantly associated with the risks of low birth weight and preterm birth, but no association was found between maternal ages and Apgar score, with the exception that ages 15-19 reduced the odds of a low one-minute score. Even though this result seems to be inconsistent, low birth weight, preterm birth and low Apgar scores measure different dimensions of newborn well-being, and the association of each measure with maternal age is expected to diverge.

    Maternal beliefs about children's social behavior may be important contributors to socialization and development, but little is known about how such beliefs form. Transactional models suggest that children's characteristics may influence parents. At 2 years of age, the shy and aggressive behaviors of 65 toddlers (28 females) were observed during interactions with an unfamiliar peer; as well, mothers described the extent to which they advocated protective and authoritarian childrearing attitudes. These variables were used to predict mothers emotions, attributions, parenting goals, and socialization strategies in response to vignettes depicting aggressive and withdrawn child behaviors 2 years later. Most child effects were moderated by maternal attitudes or gender effects. Authoritarian mothers of aggressive toddlers were most likely to report high control and anger, to blame their children for aggression, and to focus on obtaining compliance rather than teaching skills to their children. Protective mothers reported that they would use warmth and involvement to comfort withdrawn children, especially their daughters. PMID:10368918

    Prior studies have found that close mother-child sleep proximity helps increase rates of breastfeeding, and breastfeeding itself is linked to better maternal and infant health. In this study, we examine whether breastfeeding and infant bed-sharing are related to daily rhythms of the stress-responsive hormone cortisol. We found that bed-sharing was related to flatter diurnal cortisol slopes, and there was a marginal effect for breastfeeding to predict steeper cortisol slopes. Furthermore, mothers who breastfeed but do not bed-share had the steepest diurnal cortisol slopes, whereas mothers who bed-shared and did not breastfeed had the flattest slopes (P < .05). These results were significant after controlling for subjective sleep quality, perceived stress, depression, socioeconomic status, race, and maternal age. Findings from this study indicate that infant parenting choices recommended for infants (breastfeeding and separate sleep surfaces for babies) may also be associated with more optimal stress hormone profiles for mothers.

    OBJECTIVE The objective of the study was to examine fetal/infant mortality by gestational age at term stratified by maternal age. STUDY DESIGN A retrospective cohort study was conducted using 2005 US national birth certificate data. For each week of term gestation, the risk of mortality associated with delivery was compared with composite mortality risk of expectant management. The expectant management measure included stillbirth and infant death. This expectant management risk was calculated to estimate the composite mortality risk with remaining pregnant an additional week by combining the risk of stillbirth during the additional week of pregnancy and infant death risk following delivery at the next week. Maternal age was stratified by 35 years or more compared with women younger than 35 years as well as subgroup analyses of younger than 20, 20–34, 35–39, or 40 years old or older. RESULTS The fetal/infant mortality risk of expectant management is greater than the risk of infant death at 39 weeks’ gestation in women 35 years old or older (15.2 vs 10.9 of 10,000, P < .05). In women younger than 35 years old, the risk of expectant management also exceeded that of infant death at 39 weeks (21.3 vs 18.8 of 10,000, P < .05). For women younger than 35 years old, the overall expectant management risk is influenced by higher infant death risk and does not rise significantly until 41 weeks compared with women 35 years old or older in which it increased at 40 weeks. CONCLUSION Risk varies by maternal age, and delivery at 39 weeks minimizes fetal/infant mortality for both groups, although the magnitude of the risk reduction is greater in older women.

    Study question Can routine antenatal blood pressure measurements between 20 and 36 weeks’ gestation contribute to the prediction of pre-eclampsia and its associated adverse outcomes? Methods This study used repeated antenatal measurements of blood pressure from 12 996 women in the Avon Longitudinal Study of Parents and Children (ALSPAC) to develop prediction models and validated these in 3005 women from the Southampton Women’s Survey (SWS). A model based on maternal early pregnancy characteristics only (BMI, height, age, parity, smoking, existing and previous gestational hypertension and diabetes, and ethnicity) plus initial mean arterial pressure was compared with a model additionally including current mean arterial pressure, a model including the deviation of current mean arterial pressure from a stratified normogram, and a model including both at different gestational ages from 20-36 weeks. Study answer and limitations The addition of blood pressure measurements from 28 weeks onwards improved prediction models compared with use of early pregnancy risk factors alone, but they contributed little to the prediction of preterm birth or small for gestational age. Though multiple imputation of missing data was used to increase the sample size and minimise selection bias, the validation sample might have been slightly underpowered as the number of cases of pre-eclampsia was just below the recommended 100. Several risk factors were self reported, potentially introducing measurement error, but this reflects how information would be obtained in clinical practice. What this study adds The addition of routinely collected blood pressure measurements from 28 weeks onwards improves predictive models for pre-eclampsia based on blood pressure in early pregnancy and other characteristics, facilitating a reduction in scheduled antenatal care.

    Objectives To compare the food, nutrient and ‘family meal’ intakes of infants following baby-led weaning (BLW) with those of infants following a more traditional spoon-feeding (TSF) approach to complementary feeding. Study design and participants Cross-sectional study of dietary intake and feeding behaviours in 51 age-matched and sex-matched infants (n=25 BLW, 26 TSF) 6–8 months of age. Methods Parents completed a questionnaire, and weighed diet records (WDRs) on 1–3 non-consecutive days, to investigate food and nutrient intakes, the extent to which infants were self-fed or parent-fed, and infant involvement in ‘family meals’. Results BLW infants were more likely than TSF infants to have fed themselves all or most of their food when starting complementary feeding (67% vs 8%, p<0.001). Although there was no statistically significant difference in the large number of infants consuming foods thought to pose a choking risk during the WDR (78% vs 58%, p=0.172), the CI was wide, so we cannot rule out increased odds with BLW (OR, 95% CI: 2.57, 0.63 to 10.44). No difference was observed in energy intake, but BLW infants appeared to consume more total (48% vs 42% energy, p<0.001) and saturated (22% vs 18% energy, p<0.001) fat, and less iron (1.6 vs 3.6 mg, p<0.001), zinc (3.0 vs 3.7 mg, p=0.001) and vitamin B12 (0.2 vs 0.5 μg, p<0.001) than TSF infants. BLW infants were more likely to eat with their family at lunch and at the evening meal (both p≤0.020). Conclusions Infants following BLW had similar energy intakes to those following TSF and were eating family meals more regularly, but appeared to have higher intakes of fat and saturated fat, and lower intakes of iron, zinc and vitamin B12. A high proportion of both groups were offered foods thought to pose a choking risk. PMID:27154478

    The association between paternal age and the occurrence of birth defects was studied using data collected in Metropolitan Atlanta. Paternal-age information for babies born with defects was obtained from birth certificates, hospital records, and interviews with mothers; for babies born without defects, the information was obtained from birth certificates. Several statistical techniques were used to evaluate the paternal-age-birth-defects associations for 86 groups of defects. Logistic regression analysis that controlled for maternal age and race indicated that older fathers had a somewhat higher risk for having babies with defects, when all types of defects were combined; an equivalent association for older mothers was not found. Logistic regression analyses also indicated modestly higher risks for older fathers for having babies with ventricular septal defects and atrial septal defects and substantially higher risks for having babies with defects classified in the category chondrodystrophy (largely sporadic achondroplasia) and babies with situs inversus. An association between elevated paternal age and situs inversus has not been reported before; the magnitude of the estimated increased risk for situs inversus was about the same as that found in this study for chondrodystrophy.

    The population attempting pregnancy and having babies is ageing. Gynaecological and obstetric complications worsen with age. Maternity services are struggling. Increasing rates of infertility and complications are not matched by the marvels in the laboratory. This paper argues that assisted reproduction treatment has had a damaging social impact. Despite its public acclaim, it helps few and fails many more. The assisted reproduction industry could take a new and revolutionary direction towards empowering men to experience pregnancy, producing babies from artificial gametes, with a final goal being the liberation of both women and men from the burdens and dangers of pregnancy through the development of artificial wombs.

    Chromosome aneuploidy is a major cause of pregnancy loss, abnormal pregnancy and live births following both natural conception and in vitro fertilisation (IVF) and increases exponentially with maternal age in the decade preceding the menopause. Molecular genetic analysis following natural conception and spontaneous miscarriage demonstrates that trisomies arise mainly in female meiosis and particularly in the first meiotic division. Here, we studied copy number gains and losses for all chromosomes in the two by-products of female meiosis, the first and second polar bodies, and the corresponding zygotes in women of advanced maternal age undergoing IVF, using microarray comparative genomic hybridisation (array CGH). Analysis of the segregation patterns underlying the copy number changes reveals that premature predivision of chromatids rather than non-disjunction of whole chromosomes causes almost all errors in the first meiotic division and unlike natural conception, over half of aneuploidies result from errors in the second meiotic division. Furthermore, most abnormal zygotes had multiple aneuploidies. These differences in the aetiology of aneuploidy in IVF compared with natural conception may indicate a role for ovarian stimulation in perturbing meiosis in ageing oocytes. PMID:22317970

    In this study, associations were explored between maternal health and lifestyle during pregnancy and in early childhood and preschool children’s caries experience. The study is based on the Norwegian Mother and Child Cohort study conducted by the Norwegian Institute of Public Health and on data from the Public Dental Services. A total of 1348 children were followed from pregnancy to age 5 yr. A clinical dental examination was performed at age 5 yr. Questionnaires were completed by the mothers during pregnancy and the first 18 months of life, and as part of the dental examination. Results from the multivariable logistic regression analysis showed that having an obese mother (OR 2.3, 95% CI 1.3–4.1), with a diet containing more fat (OR 1.6, 95% CI 1.1 – 2.5) or sugar (OR 1.5, 95% CI 1.1–2.3) than recommended, with low education (OR 1.5, 95% CI 1.1–2.3) or having one or both parents of non-western origin (OR 5.4, 95% CI 2.8–10.6) were statistically significant risk indicators for caries experience at age 5 yr. In conclusion, maternal weight and intake of sugar and fat in pregnancy were associated with caries experience in preschool children. These characteristics may enable early referral to the dental services and preventive care to be delivered. PMID:22112032
