Abstract
ABSTRACTObjectiveTo analyze the changes in children's height, weight, BMI and rates of stunting and overweight and obesity over three periods: 1986–1987, 1996–1998, and 2023 for the community of Yalcoba in the Yucatan Peninsula.Material and MethodsFour hundred forty (6‐to‐15 years) children measured in 2023 were compared with data obtained in 1986–1987 (n = 675) and 1996–1998 (n = 628). Z‐scores of height and BMI were calculated to estimate percentages of stunting and high BMI‐for‐age (overweight and obesity). Comparisons of anthropometric parameters by sex and age groups between years of measurement were performed through one way ANOVAs.ResultsDifferences in anthropometric parameters were significant in all age groups of both sexes. Boys measured in 2023 were, on average, 6.4 and 3.3 cm taller than boys measured in the 1980s and 1990s, respectively. Increases in girls were 12 and 7.3 cm, respectively. Average increases in weight of boys measured in 2023 were 7.9 kg compared to the 1980s and 5.8 kg compared to 1990s. Average increases in girls measured in 2023 were 11.3 kg compared to the 1980s, and 7.6 kg compared to the 1990s. Stunting between the 1980s and 1990s decreased by 15 percentage points and between the 1990s and 2023 decreased by 47 percentage points. The percent of children deemed overweight/obese during these periods increased from 8 to 12–50 by 2023.ConclusionResults reflect the overall trends seen in the Yucatan where stunting has decreased substantially but the numbers of overweight/obese youths have increased dramatically in the past 30 years.

Abstract
OBJECTIVE The perinatal period and in utero environment are important for fetal growth, development, and fetal programming. This study aimed to determine the effect of parental anthropometry and the maternal metabolic milieu on offspring adiposity at 2 years of age. STUDY DESIGN This longitudinal birth cohort includes analysis of maternal (n = 337) and paternal (n = 219) anthropometry and maternal and fetal metabolic markers (n = 337), including glucose, homeostatic model of assessment (HOMA), C-peptide, and leptin from participants of the ROLO (the Randomized Control Trial of Low) pregnancy study, and their partners, to determine an association with offspring anthropometry at two years of age. RESULTS Linear regression, when adjusted for confounders, indicated maternal and paternal anthropometry and was associated with offspring weight and length at 2 years of age. Maternal height was negatively associated with general adiposity in the total cohort of children (p = 0.002) and in female children (p = 0.006) and central adiposity in the total child cohort (p < 0.001). Paternal height was also negatively associated with general adiposity in all children (p = 0.002) and central adiposity in total (p = 0.023) and female children (p = 0.008). Maternal glucose, insulin resistance, and fetal C-peptide positively correlated with anthropometry in total, male, and female children. CONCLUSION Parental anthropometry in the perinatal period has a long-lasting effect on offspring anthropometry beyond the neonatal period. Maternal and fetal metabolic factors influence adiposity, and this extends beyond the perinatal period. Parental adiposity may play a significant role in early childhood adiposity and may be a target for interventions to decrease the risk of early childhood obesity. KEY POINTS · Parental height and weight were associated with offspring anthropometry and measures of offspring adiposity at 2 years of age.. · Maternal glucose, insulin resistance, and fetal C-peptide correlated with offspring anthropometry.. · Parental anthropometry has long-term effect on offspring adiposity and is seen at 2 years of age..

PNAS NEXUS 2023; 2:pgad208. [PMID: 37388921 PMCID: PMC10306274 DOI: 10.1093/pnasnexus/pgad208] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 06/06/2023] [Accepted: 06/16/2023] [Indexed: 07/01/2023]
Abstract
Changes in growth and height reflect changes in nutritional status and health. The systematic surveillance of growth can suggest areas for interventions. Moreover, phenotypic variation has a strong intergenerational component. There is a lack of historical family data that can be used to track the transmission of height over subsequent generations. Maternal height is a proxy for conditions experienced by one generation that relates to the health/growth of future generations. Cross-sectional/cohort studies have shown that shorter maternal height is closely associated with lower birth weight of offspring. We analyzed the maternal height and offspring weight at birth in the maternity hospital in Basel, Switzerland, from 1896 to 1939 (N = ∼12,000) using generalized additive models (GAMs). We observed that average height of the mothers increased by ∼4 cm across 60 birth years and that average birth weight of their children shows a similarly shaped and upward trend 28 years later. Our final model (adjusted for year, parity, sex of the child, gestational age, and maternal birth year) revealed a significant and almost linear association between maternal height and birth weight. Maternal height was the second most important variable modeling birth weight, after gestational age. In addition, we found a significant association between maternal height and aggregated average height of males from the same birth years at time of conscription, 19 years later. Our results have implications for public health: When (female/maternal) height increases due to improved nutritional status, size at birth-and subsequently also the height in adulthood of the next generation-increases as well. However, the directions of development in this regard may currently differ depending on the world region.

Infant and Young Child Feeding Knowledge among Caregivers of Children Aged between 0 and 24 Months in Seshego Township, Limpopo Province, South Africa. Healthcare (Basel) 2023; 11:healthcare11071044. [PMID: 37046971 PMCID: PMC10094686 DOI: 10.3390/healthcare11071044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 03/26/2023] [Accepted: 04/03/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND Appropriate infant and young child feeding (IYCF) involves the initiation of breastfeeding within an hour of delivery, exclusive breastfeeding for 6 months, introduction of complementary feeding at 6 months while continuing breastfeeding for 2 years or beyond. Adequate IYCF knowledge among caregivers is associated with improved practices, lowers risk of kids developing malnutrition, infection, morbidity, and mortality. Early introduction of solid foods, mixed feeding, inadequate breastfeeding, and complementary feeding are all prevalent in South Africa. These are related to caregivers' lack of IYCF knowledge. Hence, this study aims to determine the IYCF knowledge level of caregivers of children under 24 months in the semiurban Seshego Township, South Africa. METHODOLOGY Quantitative and cross-sectional design was applied. A total of 86 caregivers were selected using simple random sampling, which is representative of a target population of 110. Structured questionnaire was utilised to gather data, and analysed through statistical software, using descriptive and inferential statistics. Chi-square test was used to calculate associations at 95% confidence interval, where a p-value of < 0.05 was considered statistically significant. RESULTS Findings show that 67% of participants had good IYCF knowledge (a score of 81 to 100%) and there was a significant relationship between knowledge and education (p = 0.001). Moreover, 40.7% did not know that exclusive breastfeeding should be up to 6 months, and 90% mentioned that breastmilk protects the child against diseases. Most participants (82.6%) know that complementary feeding should be introduced at 6 months with continuation of breastfeeding. CONCLUSIONS Caregivers know that breastfeeding should begin immediately after birth, and that it protects against diseases. Moreover, they know that solid food should be introduced at 6 months. However, there is still a need to strengthen IYCF education, particularly on exclusive breastfeeding. Interventions to improve IYCF knowledge should be intertwined with improving educational and health literacy on breastfeeding and complementary feeding.

Abstract
BACKGROUND Little is known about the transgenerational effect of nutrition deficiency in early life. This study aimed to evaluate the associations of fetal and childhood exposure to famine of parents with their offspring's risk of overweight during childhood. METHODS This analysis included a total of 3734 participants of the China Health and Nutrition Survey aged 1-17 years whose fathers and/or mothers were born in 1955-1966. These children were classified into subgroups according to parental famine exposure status (unexposed and exposed) and timing (fetal-exposed and childhood-exposed). Random effects models were applied to evaluate the associations of parental famine exposure with body mass index (BMI) and overweight of offspring. Fractional polynomial functions were adopted to describe trajectories of BMI against age. RESULTS Compared with children of unexposed parents, there was a lower risk of overweight among offspring of childhood-exposed fathers [OR (95%CI): 0.80 (0.61, 1.04)] or exposed parents [0.84 (0.68, 1.04)], particularly among male offspring, but not among those with exposed mothers only [0.98 (0.65, 1.47)]. For BMI, children with exposed mothers only had a slightly higher BMI [β(95%CI): 0.17 (-0.15, 0.49)], while those with exposed fathers only had no difference [-0.02 (-0.23, 0.19)] or exposed parents had a slightly lower BMI [-0.17 (-0.33, 0.00)] (p < 0.05 for interaction between maternal and paternal exposures). Stratified analysis showed little heterogeneity between male and female offspring, but the association between paternal childhood exposure to famine and lower overweight risk in offspring was more evident in high (vs low) paternal education group (p for interaction< 0.05). CONCLUSIONS The transgenerational associations of early-life exposure to famine with lower risks of child overweight may be via the paternal line and differ by the educational levels of parents. Further studies are warranted to confirm the results and reveal the biological mechanisms underlying.

Abstract
Background and objectives Several studies have linked longer legs with favorable adult metabolic health outcomes and greater offspring birth weight. A recent Mendelian randomization study suggested a causal link between height and cardiometabolic risk; however, the underlying reasons remain poorly understood. Methodology Using a cross-sectional design, we tested in a convenience sample of 70 healthy young women whether birth weight and tibia length as markers of early-life conditions associated more strongly with metabolically beneficial traits like organ size and skeletal muscle mass (SMM) than a statistically derived height-residual variable indexing later, more canalized growth. Results Consistent with the 'developmental origins of health and disease' hypothesis, we found relatively strong associations of tibia length-but not birth weight-with adult organ size, brain size, SMM and resting energy expenditure measured by magnetic resonance imaging (MRI), dual-energy X-ray absorptiometry and indirect calorimetry, respectively. Conclusions and implications Building on prior work, these results suggest that leg length is a sensitive marker of traits directly impacting metabolic and reproductive health. Alongside findings in the same sample relating tibia length and height-residual to MRI-measured pelvic dimensions, we suggest there may exist a degree of coordination in the development of long bone, lean mass and pelvic traits, possibly centered on early, pre-pubertal growth periods. Such phenotypic coordination has important implications for fitness, serving to benefit both adult health and the health of offspring in subsequent generations.

Abstract
Evidence that fetal nutrition influences adult health has heightened interest in nutritional interventions targeting pregnancy. However, as is true for other placental mammals, human females have evolved mechanisms that help buffer the fetus against short-term fluctuations in maternal diet and energy status. In this review, we first discuss the evolution of increasingly elaborate vertebrate strategies of buffering offspring from environmental fluctuations during development, including the important innovation of the eutherian placenta. We then present the Maternal Nutritional Buffering Model, which argues that, in contrast to many micronutrients that must be derived from dietary sources, the effects of short-term changes in maternal macronutrient intake during pregnancy, whether due to a deficit or supplementation, will be minimized by internal buffering mechanisms that work to ensure a stable supply of essential resources. In contrast to the minimal effects of brief macronutrient supplementation, there is growing evidence that sustained improvements in early life and adult pre-pregnancy nutrition could improve birth outcomes in offspring. Building on these and other observations, we propose that strategies to improve fetal macronutrient delivery will be most effective if they modify the pregnancy metabolism of mothers by targeting nutrition prior to conception and even during early development, as a complement to the conventional focus on bolstering macronutrient intake during pregnancy itself. Our model leads to the prediction that birth weight will be more strongly influenced by the mother’s chronic pre-pregnancy nutrition than by pregnancy diet, and highlights the need for policy solutions aimed at optimizing future, intergenerational health outcomes. Lay summary: We propose that strategies to improve fetal macronutrient delivery will be most effective if they modify the pregnancy metabolism of mothers by targeting nutrition prior to conception and even during early development, as a complement to the conventional focus on bolstering macronutrient intake during pregnancy itself.

Abstract
BACKGROUND Undernutrition and poor cognitive development affect many children in developing countries. Good nutrition and health care are essential for optimal child development and growth. OBJECTIVES We assessed the impact of peer counseling combined with psychosocial stimulation on feeding practices and child growth and development in slums in Bangladesh. METHODS We performed a community-based cluster randomized controlled trial in selected slums; 350 mother-infant pairs were allocated to receive peer counseling on feeding practices plus psychosocial stimulation (PC + PCS; n = 175) or usual health messages (control; n = 175) using restricted randomization. Data were collected at enrollment and 1, 3, 5, 7, 9, and 12 mo after delivery. We collected data on infant and young child feeding practices and anthropometric measurements from birth until 12 mo to assess the main outcomes, including feeding practices and growth. We used the Bayley Scale III at 12 mo to assess child development. The effects of the PC + PCS intervention were assessed by using regression models. RESULTS More mothers in the PC + PCS group than in the control group reported early initiation of breastfeeding (in the first hour: 89% compared with 78%, respectively; P < 0.05) and exclusive breastfeeding at 5 mo (73% compared with 27%, respectively; P < 0.001). Peer counseling had positively impacted infant length gain at 12 mo (P < 0.005). Children in the PC + PCS group were found to be more socially and emotionally active compared with controls at 12 mo (standardized score: 0.165 compared with -0.219, respectively; P < 0.05). CONCLUSION Combining peer counseling with psychosocial stimulation had positive effects on infant feeding practices and growth at 12 mo and on the social-emotional development of young children. This trial was registered at clinicaltrial.gov as NCT03040375.

Abstract
To determine possible variations in children's health status and mortality associated with variations in maternal stature, an anthropometric and demographic study was conducted in a Roma population of poor socio-economic status in rural Serbia. Data were collected during several years of anthropological fieldwork. The sample consisted of 691 women, ranging from 16 to 80 years of age. In addition to stature, Roma women's demographics, reproductive history, reproductive outcomes and health status of their children were collected. The results provide evidence of a significant association between mother's stature and their children's health and mortality, with a shorter mother's stature predisposing children to poor health and survival outcomes. The findings could prompt development of a definition of short stature among Roma women to evaluate the risk based on height distribution among the general Roma population.

Abstract
OBJECTIVES To investigate the influence of parental chronic spinal pain on prognosis of chronic spinal pain in adult offspring, and whether offspring physical activity level and body mass index (BMI) modified this association. DESIGN Prospective cohort study. SETTING We used family-linked longitudinal data from the Norwegian HUNT study collected in HUNT2 (1995-1997) and HUNT3 (2006-2008). PARTICIPANTS A total of 1529 offspring who reported spinal pain in HUNT2 were linked with parental data and followed up in HUNT3. OUTCOMES We estimated relative risk (RR) with 95% CI for recovery from chronic spinal pain, and also from activity limiting spinal pain, in offspring related to chronic spinal pain in parents. We also investigated whether offspring leisure time physical activity and BMI modified these intergenerational associations in spinal pain. RESULTS A total of 540 (35%) offspring were defined as recovered after approximately 11 years of follow-up. Offspring with both parents reporting chronic spinal pain were less likely to recover from chronic spinal pain (RR 0.83, 95% CI 0.69 to 0.99) and activity limiting spinal pain (RR 0.71, 95% CI 0.54 to 0.94), compared with offspring of parents without chronic spinal pain. Analyses stratified by BMI and physical activity showed no strong evidence of effect modification on these associations. However, offspring who were overweight/obese and with both parents reporting chronic spinal pain had particularly low probability of recovery from activity limiting spinal pain, compared with those who were normal weight and had parents without chronic spinal pain (RR 0.57, 95% CI 0.39 to 0.84). CONCLUSION Offspring with chronic spinal pain are less likely to recover if they have parents with chronic spinal pain, particularly if offspring are overweight/obese.

Abstract
AbstractObjectiveTo retrospectively investigate the association between short stature and increased sitting height ratio (SHR) – indicators of stunting – and obesity markers in adults.DesignCross-sectional evaluation of the EPIPorto cohort. Weight, height, sitting height and waist circumference were measured. Obesity was assessed for men and women through BMI and waist-to-height ratio (WHtR). Short stature (women, <152 cm; men, <164 cm) and high SHR (women, ≥54·05 %; men, ≥53·25 %) were taken as stunting measures. OR with 95 % CI were computed using logistic regression models.SettingRepresentative sample of adults from EPIPorto, an adult cohort study from Porto, Portugal.SubjectsA sample of 1682 adults, aged 18–86 years, was analysed.ResultsHigher obesity prevalence was found among women (BMI≥30·0 kg/m2: 25·5v.13·3 %,P<0·001) and a higher proportion of men presented abdominal obesity (WHtR≥0·5: 80·1v.71·1 %,P<0·001). A positive association was found between short stature and obesity measures for women (multivariate-adjusted OR; 95 % CI: 1·75; 1·17, 2·62 for BMI≥30·0 kg/m2; 1·89; 1·24, 2·87 for WHtR≥0·5). Increased SHR was associated with higher likelihood of having BMI≥30·0 kg/m2in both sexes (multivariate-adjusted OR; 95 % CI: 2·10; 1·40, 3·16 for women; 1·92; 1·07, 3·43 for men) but not with WHtR≥0·5.ConclusionsDifferent growth markers are associated with obesity in adults. However, this association depends on the population and anthropometric measures used: short stature is associated with a higher risk of presenting excessive weight in women but not in men; SHR is more sensitive to detect this effect in both sexes.

Wells JCK, Figueiroa JN, Alves JG. Maternal pelvic dimensions and neonatal size: Implications for growth plasticity in early life as adaptation. Evol Med Public Health 2018; 2017:191-200. [PMID: 29423225 PMCID: PMC5798154 DOI: 10.1093/emph/eox016] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2017] [Accepted: 10/02/2017] [Indexed: 01/05/2023] Open
Abstract
Patterns of fetal growth predict non-communicable disease risk in adult life, but fetal growth variability appears to have a relatively weak association with maternal nutritional dynamics during pregnancy. This challenges the interpretation of fetal growth variability as 'adaptation'. We hypothesized that associations of maternal size and nutritional status with neonatal size are mediated by the dimensions of the maternal pelvis. We analysed data on maternal height, body mass index (BMI) and pelvic dimensions (conjugate, inter-spinous and inter-cristal diameters) and neonatal gestational age, weight, length, thorax girth and head girth (n = 224). Multiple regression analysis was used to identify independent maternal predictors of neonatal size, and the mediating role of neonatal head girth in these associations. Pelvic dimensions displaced maternal BMI as a predictor of birth weight, explaining 11.6% of the variance. Maternal conjugate and inter-spinous diameters predicted neonatal length, thorax girth and head girth, whereas inter-cristal diameter only predicted neonatal length. Associations of pelvic dimensions with birth length, but not birth weight, were mediated by neonatal head girth. Pelvic dimensions predicted neonatal size better than maternal BMI, and these associations were mostly independent of maternal height. Sensitivity of fetal growth to pelvic dimensions reduces the risk of cephalo-pelvic disproportion, potentially a strong selective pressure during secular trends in height. Selection on fetal adaptation to relatively inflexible components of maternal phenotype, rather than directly to external ecological conditions, may help explain high levels of growth plasticity during late fetal life and early infancy.

Abstract
We investigated intergenerational associations of adolescent mothers' and grandmothers' anthropometrics and schooling with adolescent mothers' offspring's anthropometrics in Ethiopia, India, Peru, and Vietnam. We examined birthweight (n = 283), birthweight Z-score (BWZ), conditional growth in weight-for-age Z-score (cWAZ, residuals from a regression of WAZ at last survey round on BWZ, sex, and age), and height-for-age Z-score (HAZ) of children born to older cohort adolescent girls in the Young Lives study. Our key independent variables were adolescent mothers' body size: HAZ and body-mass-index-for-age Z-score (BMIZ) at age 8, conditional HAZ (cHAZ, residuals from a regression of HAZ at the end of a growth period on prior HAZ, age, and sex), conditional BMIZ growth (cBMIZ, calculated analogously), and grandmaternal BMIZ, HAZ, and schooling. We adjusted for child, maternal, and household characteristics. Adolescent mothers' cHAZ (ages 8-15) predicted birthweight (β = 130 g, 95% confidence interval (CI) 31-228), BWZ (β = 0.31, CI 0.09-0.53), and cWAZ (β = 0.28, CI 0.04-0.51). Adolescent mothers' BMIZ at age 8 predicted birthweight (β = 79 g, CI 16-43) and BWZ (β = 0.22, CI 0.08-0.36). Adolescent mothers' cBMIZ (ages 12-15) predicted child cWAZ and HAZ. Grandmothers' schooling predicted grandchild birthweight (β = 22 g, CI 1-44) and BWZ (β = 0.05, CI 0.01-0.10).

Abstract
BACKGROUND/AIMS Childhood stunting is a prevalent problem in low- and middle-income countries and is associated with long-term adverse neurodevelopment and health outcomes. In this review, we define indicators of growth, discuss key challenges in their analysis and application, and offer suggestions for indicator selection in clinical research contexts. METHODS Critical review of the literature. RESULTS Linear growth is commonly expressed as length-for-age or height-for-age z-score (HAZ) in comparison to normative growth standards. Conditional HAZ corrects for regression to the mean where growth changes relate to previous status. In longitudinal studies, growth can be expressed as ΔHAZ at 2 time points. Multilevel modeling is preferable when more measurements per individual child are available over time. Height velocity z-score reference standards are available for children under the age of 2 years. Adjusting for covariates or confounders (e.g., birth weight, gestational age, sex, parental height, maternal education, socioeconomic status) is recommended in growth analyses. CONCLUSION The most suitable indicator(s) for linear growth can be selected based on the number of available measurements per child and the child's age. By following a step-by-step algorithm, growth analyses can be precisely and accurately performed to allow for improved comparability within and between studies.

Abstract
BACKGROUND The first 1000 days of life is a critical period of infant growth that has been linked to future adult health. Understanding prenatal factors that contribute to variation in growth during this period could inform successful prevention strategies. METHODS Prenatal and maternal characteristics, including prepregnancy obesity and gestational weight gain were evaluated in relation to weight growth trajectories during the first 24 months of life using the SuperImposition by Translation and Rotation (SITAR) method, which provides estimates of infant size, timing to peak velocity, and growth velocity. The study sample included 704 mother-infant dyads from a multiethnic prebirth cohort from the Southeastern United States. The total number of weight measures was 8670 (median number per child = 14). RESULTS Several prenatal and maternal characteristics were linked with infant growth parameters. The primary findings show that compared to women with a prepregnancy BMI between 18 and 24.9, women with a prepregnancy BMI ≥40 had infants that were 8% larger during the first 24 months, a delayed tempo of around 9 days, and a slower velocity. Mothers who had greater than adequate gestational weight gain had infants that were 5% larger even after controlling for prepregnancy BMI and several other covariates. CONCLUSIONS The findings contribute new data on the associations between gestational weight gain and aspects of early growth using the SITAR method, and support a growing consensus in the literature that both prepregnancy BMI and gestational weight gain relate independently to risk for greater postnatal weight growth.

Familial Risk of Chronic Musculoskeletal Pain and the Importance of Physical Activity and Body Mass Index: Prospective Data from the HUNT Study, Norway. PLoS One 2016; 11:e0153828.

Abstract
The main objectives of the current study was i) to prospectively examine if chronic musculoskeletal pain in parents is associated with risk of chronic musculoskeletal pain in their adult offspring, and ii) to assess if these parent-offspring associations are modified by offspring body mass index and leisure time physical activity. We used data on 4,742 adult offspring linked with their parents who participated in the population-based HUNT Study in Norway in 1995–97 and in 2006–08. Family relations were established through the national Family Registry. A Poisson regression model was used to estimate relative risk (RR) with 95% confidence interval (CI). In total, 1,674 offspring (35.3%) developed chronic musculoskeletal pain during the follow-up period of approximately 11 years. Both maternal (RR: 1.26, 95% CI: 1.03, 1.55) and paternal chronic musculoskeletal pain (RR: 1.29, 95% CI: 1.06, 1.57) was associated with increased risk of offspring chronic musculoskeletal pain. Compared to offspring of parents without chronic musculoskeletal pain, the adverse effect of parental pain was somewhat stronger among offspring who reported a low (RR: 1.82, 95% CI: 1.32, 2.52) versus high (RR: 1.32, 95% CI: 0.95, 1.84) level of leisure time physical activity. Offspring of parents with chronic musculoskeletal pain and who were classified as obese had more than twofold increased risk (RR: 2.33, 95% CI: 1.68, 3.24) of chronic musculoskeletal pain compared to normal weight offspring of parents without pain. In conclusion, parental chronic musculoskeletal pain is positively associated with risk of chronic musculoskeletal pain in their adult offspring. Maintenance of normal body weight may reduce the risk of chronic musculoskeletal pain in offspring of pain-afflicted parents.

Abstract
We conducted a systematic review and meta-analysis of population-based cohort studies of maternal body mass index (BMI) and risk of adverse birth and health outcomes in low- and middle-income countries. PubMed, Embase, CINAHL and the British Nursing Index were searched from inception to February 2014. Forty-two studies were included. Our study found that maternal underweight was significantly associated with higher risk of preterm birth (odds ratio [OR], 1.13; 95% confidence interval [CI], 1.01-1.27), low birthweight (OR, 1.66; 95% CI, 1.50-1.84) and small for gestational age (OR, 1.85; 95% CI, 1.69-2.02). Compared with mothers with normal BMI, overweight or obese mothers were at increased odds of gestational diabetes, pregnancy-induced hypertension, pre-eclampsia, caesarean delivery and post-partum haemorrhage. The population-attributable risk (PAR) indicated that if women were entirely unexposed to overweight or obesity during the pre-pregnancy or early pregnancy period, 14% to 35% fewer women would develop gestational diabetes, pre-eclampsia or pregnancy-induced hypertension in Brazil, China, India, Iran or Thailand. The highest PAR of low birthweight attributable to maternal underweight was found in Iran (20%), followed by India (18%), Thailand (10%) and China (8%). Treatment and prevention of maternal underweight, overweight or obesity may help reduce the burden on maternal and child health in developing countries.

Abstract
Background. Chronic poor oral health has a high prevalence in Appalachia, a large region in the eastern USA. The Center for Oral Health Research in Appalachia (COHRA) has been enrolling pregnant women and their babies since 2011 in the COHRA2 study of genetic, microbial, and environmental factors involved in oral health in Northern Appalachia. Methods. The COHRA2 protocol is presented in detail, including inclusion criteria (healthy, adult, pregnant, US Caucasian, English speaking, and nonimmunocompromised women), recruiting (two sites: Pittsburgh, Pennsylvania, and West Virginia, USA), assessments (demographic, medical, dental, psychosocial/behavioral, and oral microbial samples and DNA), timelines (longitudinal from pregnancy to young childhood), quality control, and retention rates. Results. Preliminary oral health and demographic data are presented in 727 pregnant women, half from the greater Pittsburgh region and half from West Virginia. Despite similar tooth brushing and flossing habits, COHRA2 women in West Virginia have significantly worse oral health than the Pittsburgh sample. Women from Pittsburgh are older and more educated and have less unemployment than the West Virginia sample. Conclusions. We observed different prevalence of oral health and demographic variables between pregnant women from West Virginia (primarily rural) and Pittsburgh (primarily urban). These observations suggest site-specific differences within Northern Appalachia that warrant future studies.

Abstract
OBJECTIVES To test the hypothesis that living conditions experienced by maternal grandmothers (F1 generation) and mothers (F2 generation) during their childhood are related to height and leg length (LL: height - sitting height) of their 6-to-8 year old children (F3 generation). METHODS From September 2011 to June 2012 we obtained height and LL, and calculated z-score values of these measurements for 109 triads (F1 , F2 , F3 ) who are Maya living in Merida, Yucatan, Mexico. Multiple regression models were adjusted to examine the relation of anthropometric and intergenerational socioeconomic parameters of F1 (house index and family size during childhood) and F2 (paternal job loss during childhood) with the z-score values of height and LL of F3 . RESULTS Children's height and LL were positively associated with maternal height and LL. This association was relatively stronger in LL. Better categories of grand-maternal house index were significantly associated with higher values of height and LL in grandchildren. Grand-maternal family size was positively related with LL, but not with height. CONCLUSIONS Our findings partially support the hypothesis that living conditions experienced by recent maternal ancestors (F1 and F2 ) during their growth period influence the growth of descendants (F3 ). Results suggest that LL is more sensitive to intergenerational influences than is total height and that the transition from a traditional rural lifestyle to urban conditions results in new exposures for risk in human physical growth.

Abstract
BACKGROUND Chronic pain in the neck and low back is highly prevalent. Although heritable components have been identified, knowledge about generational transmission of spinal pain between parents and their adult offspring is sparse. METHODS This study examined the intergenerational association of spinal pain using data from 11,081 parent-offspring trios participating in the population-based HUNT Study in Norway. Logistic regression was used to calculate adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for offspring spinal pain associated with parental spinal pain. RESULTS In total, 3654 (33%) offspring reported spinal pain at participation. Maternal and paternal spinal pain was consistently associated with higher ORs for offspring spinal pain. The results suggest a slightly stronger association for parental multilevel spinal pain (i.e., both neck/upper back pain and low back pain) than for pain localized to the neck/upper back or low back. Multilevel spinal pain in both parents was associated with ORs of 2.6 (95% CI, 2.1-3.3), 2.4 (95% CI, 1.9-3.1) and 3.1 (95% CI, 2.2-4.4) for offspring neck/upper back, low back and multilevel spinal pain, respectively. CONCLUSION Parental chronic spinal pain was consistently associated with increased occurrence of chronic spinal pain in their adult offspring, and this association was particularly strong for multilevel spinal pain.

Abstract
Background Little is known about the association between parental chronic musculoskeletal pain (CMP) and occurrence of CMP in the adult offspring. The main objective of this study was to assess the parent-offspring association of CMP, and also to examine possible modifying effects of age and sex. Methods The study includes 11 248 parent-offspring trios from the Norwegian HUNT Study with information on parental CMP obtained in 1995–97 and offspring CMP obtained in 2006–08. Logistic regression was used to calculate adjusted odds ratios (ORs) for offspring CMP associated with parental CMP. Results Maternal and paternal CMP was associated with 20-40% increased odds of CMP in sons and daughters. Both sons and daughters had an OR of 1.6 (95% CI 1.4 to 1.9) when both parents reported CMP, compared to when none of the parents had CMP. Restricting the analyses to parental CMP that was associated with limited work ability and leisure time activity did not change the strength of the association. Further, analyses stratified by parental age ±65 years showed no clear difference in the estimated associations, and there was no evidence of interaction for parental sex (P ≥ 0.39) or offspring age ±40 years (P ≥ 0.26). Conclusions This large family-linkage study show that maternal and paternal CMP are positively associated with CMP in the adult offspring, irrespective of parental and offspring age, and that the associations are strongest when both parents have CMP. Although the high prevalence of CMP in both parents and offspring suggests that not all cases are clinically relevant, the results suggest that chronic pain has a heritable component.

Abstract
BACKGROUND After decades of steady increase, mean birthweight in the US declined throughout the 1990s and early 2000s, a trend not fully explained by changes in length of gestation, medical practice, demographics, or maternal behaviours. We hypothesised that secular changes in health or social factors across women's life courses may have contributed to this unexplained trend and examined maternal birth cohort as a proxy measure of life-course determinants of fetal growth in the US. METHODS We used the age, period, and cohort (APC) intrinsic estimator (IE) approach to estimate the contribution of maternal birth cohort (independent of maternal age and period of birth) to small for gestational age (SGA), overall and among term births, in the US from 1989 to 2010. We conducted analyses separately among foreign- and US-born Hispanic, non-Hispanic black (NHB), and non-Hispanic white mothers. RESULTS We found evidence of a U-shaped relationship between maternal birth cohort and SGA among NHB women only. After accounting for maternal age and period of birth, risk of SGA among NHB women born in 1950 was 21.1% and decreased to 15.9% in 1970. However, NHB women born after 1970 experienced increasing risk (19.6% by the 1986 birth cohort). CONCLUSIONS Our findings suggest that NHB women born after 1970 have experienced increasing risk of SGA. Declining risk of SGA across NHB maternal birth cohorts from 1950 to 1970, however, suggests the potential to reverse this trend. Results illustrate the need for research on health and social risk factors for SGA across the pre-pregnancy life course.

Abstract
BACKGROUND Studying prenatal influences of early life growth is relevant to life-course epidemiology as some of its features have been linked to the onset of later diseases. METHODS We studied the association between prenatal maternal characteristics (height, age, parity, education, pre-pregnancy body mass index (BMI), smoking, gestational diabetes and hypertension) and offspring weight trajectories in infancy using SuperImposition by Translation And Rotation (SITAR) models, which parameterize growth in terms of three biologically interpretable parameters: size, velocity and tempo. We used data from three contemporary cohorts based in Portugal (GXXI, n=738), Italy (NINFEA, n=2,925), and Chile (GOCS, n=959). RESULTS Estimates were generally consistent across the cohorts for maternal height, age, parity and pre-pregnancy overweight/obesity. Some exposures only affected one growth parameter (e.g. maternal height (per cm): 0.4% increase in size (95% confidence interval (CI):0.3; 0.5)), others were either found to affect size and velocity (e.g. pre-pregnancy underweight vs normal weight: smaller size (-4.9%, 95% CI:-6.5; -3.3), greater velocity (5.9%, 95% CI:1.9;10.0)), or to additionally influence tempo (e.g. pre-pregnancy overweight/obesity vs normal weight: increased size (7.9%, 95% CI:4.9;10.8), delayed tempo (0.26 months, 95% CI:0.11;0.41), decreased velocity (-4.9%, 95% CI: -10.8;0.9)). CONCLUSIONS By disentangling the growth parameters of size, velocity and tempo, we found that prenatal maternal characteristics, especially maternal smoking, pre-pregnancy overweight and underweight, parity and gestational hypertension, are associated with different aspects of infant weight growth. These results may offer insights into the mechanisms governing infant growth.

Abstract
BACKGROUND Cardiovascular risk factors are transmitted from parents to offspring; however, the relative contributions of fathers and mothers remain unclear. If maternal exposures during pregnancy influence offspring through the intrauterine environment, associations between mothers and offspring are expected to be stronger than between fathers and offspring. In this family linkage study we compared father-offspring and mother-offspring associations of several cardiovascular risk factors. METHODS The study population consisted of 36,528 father-mother-offspring trios who participated at one or more surveys of the HUNT Study, Norway in 1984-86, 1995-97 and 2006-08. Parent-offspring associations were assessed using unstandardized and standardized residuals from linear regression analysis, and possible non-paternity was accounted for in sensitivity analyses. RESULTS Age- and sex-adjusted parent-offspring associations for anthropometric factors, blood pressure, blood lipids, blood glucose and resting heart rate were largely similar between fathers and mothers. Use of standardized values and analyses adjusted for non-paternity further emphasized this similarity. CONCLUSIONS This study found largely similar father-offspring and mother-offspring associations across all cardiovascular risk factors under study, arguing against strong maternal effects transmitted through intrauterine mechanisms.

Abstract
BACKGROUND Childhood overweight and obesity is a global public health concern. For girls in particular, being overweight or obese during pre-adolescence (aged 7-11 years) has intergenerational implications for both the mother and her future offspring. In the United Kingdom (UK) there is increasing interest in community targeted interventions but less is known about how to tailor these approaches to the needs of the community. This study applied the Community Readiness Model (CRM), for the first time in the UK, to demonstrate its applicability in designing tailored interventions. METHODS Community readiness assessment was conducted using semi-structured key informant interviews. The community's key informants were identified through focus groups with pre-adolescent girls. The interviews addressed the community's efforts; community knowledge of the efforts; leadership; community climate; community knowledge of the issue and resources available to support the issue. Interviews were conducted until the point of theoretical saturation and questions were asked separately regarding physical activity (PA) and healthy eating and drinking (HED) behaviours. The interviews were transcribed verbatim and were firstly analysed thematically and then scored using the assessment guidelines produced by the CRM authors. RESULTS Readiness in this community was higher for PA than for HED behaviours. The lowest scores related to the community's 'resources' and the 'community knowledge of the issue'; affirming these two issues as the most appropriate initial targets for intervention. In terms of resources, there is also a need for resources to support the development of HED efforts beyond the school. Investment in greater physical education training for primary school teachers was also identified as an intervention priority. To address the community's knowledge of the issue, raising the awareness of the prevalence of pre-adolescent girls' health behaviours is a priority at the local community level. Inconsistent school approaches contributed to tensions between schools and parents regarding school food policies. CONCLUSIONS This study has identified the readiness level within a UK community to address the behaviours related to overweight and obesity prevention in pre-adolescent girls. The focus of an intervention in this community should initially be resources and raising awareness of the issue within the community.

Abstract
Understanding the conditions under which families try to influence members' health-related practices can provide information to build concepts adding to models of health promotion. This paper reports on an exploratory qualitative study examining the influences of intergenerational relationships in shaping beliefs, knowledge and practices about health and illness in a regional Australian city. We conducted semi-structured interviews with 27 adults with family members of other generations living in the city, all of whom had experience of asthma. We found that overall people's experience of health and illness, particularly in childhood, was taken for granted and not reflected upon. It was in the face of serious illness or death of a family member that objective knowledge about health and illness was sought and integrated within the family leading, in most cases, to significant lifestyle changes or 'doing things differently'. We drew on Bourdieu's concept of the three forms of theoretical knowledge in analysing our findings. We found the concept of knowledge as 'primary taken-for-granted experience', and the concept of praxeological knowledge as the knowledge created by the dialectical relationships between an individual subject and objectives structures were helpful. To influence individual health practices, we need to acknowledge how the family context confirms the taken-for-granted health practices of an individual and the family circumstances that might lead families to seek objective knowledge and make lifestyle changes to promote health.

Abstract
Background Adult height is known to be inversely related to coronary heart disease (CHD) risk. We sought to investigate transgenerational influence of parental height on offspring’s CHD risk. Methods Parents took part in a cardiorespiratory disease survey in two Scottish towns during the 1970s, in which their physical stature was measured. In 1996, their offspring were invited to participate in a similar survey, which included an electrocardiogram recording and risk factor assessment. Results A total of 2306 natural offspring aged 30–59 years from 1456 couples were subsequently flagged for notification of mortality and followed for CHD-related hospitalizations. Taller paternal and/or maternal height was associated with socio-economic advantage, heavier birthweight and increased high-density lipoprotein cholesterol in offspring. Increased height in fathers, but more strongly in mothers (risk ratio for 1 SD change in maternal height = 0.85; 95% confidence interval: 0.76 to 0.95), was associated with a lower risk of offspring CHD, adjusting for age, sex, other parental height and CHD risk factors. Conclusion There is evidence of an association between taller parental, particularly maternal, height and lower offspring CHD risk. This may reflect an influence of early maternal growth on the intrauterine environment provided for her offspring.

Abstract
Intergenerational effects on linear growth are well documented. Several generations are necessary in animal models to 'wash out' effects of undernutrition, consistent with the unfolding of the secular trend in height in Europe and North America. Birthweight is correlated across generations and short maternal stature, which reflects intrauterine and infant growth failure, is associated with low birthweight, child stunting, delivery complications and increased child mortality, even after adjusting for socio-economic status. A nutrition intervention in Guatemala reduced childhood stunting; it also improved growth of the next generation, but only in the offspring of girls. Possible mechanisms explaining intergenerational effects on linear growth are not mutually exclusive and include, among others, shared genetic characteristics, epigenetic effects, programming of metabolic changes, and the mechanics of a reduced space for the fetus to grow. There are also socio-cultural factors at play that are important such as the intergenerational transmission of poverty and the fear of birthing a large baby, which leads to 'eating down' during pregnancy. It is not clear whether there is an upper limit for impact on intrauterine and infant linear growth that programmes in developing countries could achieve that is set by early childhood malnutrition in the mother. Substantial improvements in linear growth can be achieved through adoption and migration, and in a few selected countries, following rapid economic and social development. It would seem, despite clear documentation of intergenerational effects, that nearly normal lengths can be achieved in children born to mothers who were malnourished in childhood when profound improvements in health, nutrition and the environment take place before conception. To achieve similar levels of impact through public health programmes alone in poor countries is highly unlikely. The reality in poor countries limits the scope, quality and coverage of programmes that can be implemented and modest impact should be expected instead. The Lancet series on Maternal and Child Undernutrition estimated that implementation to scale of proven interventions in high burden countries would reduce stunting by one-third; this is perhaps a realistic upper bound for impact for high quality programmes, unless accompanied by sweeping improvements in social services and marked reductions in poverty. Finally, because so much can be achieved in a single generation, intergenerational influences are unlikely to be an important explanation for lack of programme impact aimed at the window of the first 1000 days. Failure to prevent linear growth failure in developing countries has serious consequences for short- and long-term health as well as for the formation of human capital. The nutrition transition has created a double burden by adding obesity and related chronic diseases to the public health agenda of countries still struggling with the 'old' problems of maternal and child undernutrition. The challenge ahead is to increase efforts to prevent linear growth failure while keeping child overweight at bay.

Abstract
Previous research links both low birth weight (LBW) and relative leg length (RLL) to a similar set of adult pathologies, including type II diabetes, coronary vascular disease, and some cancers. Historically, LBW has been frequently used as a broad indicator of the quality of the intrauterine environment, while RLL has been considered a sensitive measure of childhood environmental quality. While these observations have been taken to suggest that these measures reflect independent exposures at different life-stages, their mutual association with a similar set of later pathologies makes this assumption less certain than it may have previously seemed. Nationally representative data from the Third National Health and Nutrition Examination Survey (NHANES III) are used to test the hypothesis that LBW predicts reductions in the development of leg length relative to stature. After controls for important socioeconomic exposures that might confound measurement of such a relationship, we find statistical and biological evidence that variation in birth weight and variation in the development of leg length relative to stature (RLL) are independent. The results suggest that these two measures may represent independent information on prenatal and postnatal environmental quality.

Abstract
Childhood overweight/obesity is recognized as an increasing health problem. The objective of this review was to determine the effectiveness of interventions designed to prevent overweight and obesity in pre-adolescent girls. The papers included were those studying children (must include results for girls) from within the 7-11 years age range from any country and ethnic background. The included interventions lasted at least 12 weeks and modified a combination of nutrition, physical activity, knowledge, attitudes or health-related behaviours associated with the development of childhood overweight and obesity. Effect sizes were calculated where possible using Cohen's classifications of small (0.2-0.5), medium (0.5-0.8) and large (>0.8) effect sizes. Thirty studies met the inclusion criteria of which four were cluster randomized controlled trials, 14 were randomized controlled trials, 11 were controlled trials and one was a cohort pre-post trial. There were four weak, 11 moderate and 15 strong quality studies. Eleven studies were considered short term and 19 long term (≥12 months). There were 66 effect sizes less than 0.2, 56 categorized as low, 16 as medium and two as high. There is the potential for interventions aimed at pre-adolescent girls to reduce the risk factors associated with childhood overweight and obesity, although the sustainability of the effects of such interventions is less clear.

OBJECTIVE The objective of this study was to examine the influence of parental BMI on childhood undernutrition in India. METHODS The study population was a nationally representative cross-sectional sample of singleton children (n = 15976) who were aged 0 to 59 months from the 2005-2006 Indian National Family Health Survey. Information was obtained by a face-to-face interview with the mother with a 94.5% response rate. Modified Poisson regression models that account for multistage survey design and sampling weights were applied to estimate the associations between parental BMI and childhood undernutrition. The outcome measures were child underweight, stunting, and wasting; parental BMI was the primary exposure. RESULTS In mutually adjusted models, an increase in 1 unit of maternal BMI was associated with a lower relative risk (RR) for childhood undernutrition (underweight RR: 0.957 [95% confidence interval [CI]: 0.947-0.967]; stunting RR: 0.985 [95% CI: 0.977-0.993]; wasting RR: 0. 941 [95% CI: 0.926-0.958]). The association between paternal BMI and childhood undernutrition was similar to that observed for maternal BMI (underweight RR: 0.961 [95% CI: 0.951-0.971]; stunting RR: 0.986 [95% CI: 0.978-0.995]; wasting RR: 0.965 [95% CI: 0.947-0.982]). CONCLUSIONS Similarity in the association between paternal/maternal BMI and childhood undernutrition suggests that intergenerational associations in nutritional status are not driven by maternal intrauterine influences.

Abstract
Decomposing stature into its major components is proving to be a useful strategy to assess the antecedents of disease, morbidity and death in adulthood. Human leg length (femur + tibia), sitting height (trunk length + head length) and their proportions, for example, (leg length/stature), or the sitting height ratio (sitting height/stature x 100), among others) are associated with epidemiological risk for overweight (fatness), coronary heart disease, diabetes, liver dysfunction and certain cancers. There is also wide support for the use of relative leg length as an indicator of the quality of the environment for growth during infancy, childhood and the juvenile years of development. Human beings follow a cephalo-caudal gradient of growth, the pattern of growth common to all mammals. A special feature of the human pattern is that between birth and puberty the legs grow relatively faster than other post-cranial body segments. For groups of children and youth, short stature due to relatively short legs (i.e., a high sitting height ratio) is generally a marker of an adverse environment. The development of human body proportions is the product of environmental x genomic interactions, although few if any specific genes are known. The HOXd and the short stature homeobox-containing gene (SHOX) are genomic regions that may be relevant to human body proportions. For example, one of the SHOX related disorders is Turner syndrome. However, research with non-pathological populations indicates that the environment is a more powerful force influencing leg length and body proportions than genes. Leg length and proportion are important in the perception of human beauty, which is often considered a sign of health and fertility.

Abstract
There is particular interest in understanding socioeconomic and ethnic variability in health status. The developmental origins of disease hypothesis emphasize the importance of growth patterns across the life-course in relation to noncommunicable disease risk. The physiological components of cardiovascular risk, collectively termed the metabolic syndrome, derive in part from a disparity between the homeostatic "metabolic capacity" of vital organs and the "metabolic load" induced by large tissue masses, a rich diet and sedentary behavior. From an evolutionary perspective, the risk of such disparity is decreased by maternal physiology regulating offspring growth trajectory during gestation and lactation. Maternal capital, defined as phenotypic resources enabling investment in the offspring, allows effective buffering of the offspring from nutritional perturbations and represents the environmental niche initially occupied by the offspring. Offspring growth patterns are sensitive to the magnitude of maternal capital during early windows of plasticity. Offspring life-history strategy can then respond adaptively to further factors across the life-course, but only within the context of this initial maternal influence on growth. Maternal somatic capital is primarily gained or lost across generations, through variable rates of fetal and infant growth. I argue that the poor nutritional experience of populations subjected to colonialism resulted in a systematic loss of maternal capital, reflected in downward secular trends in stature. Accelerating the recovery of somatic capital within generations overloads metabolic capacity and exacerbates cardiovascular risk, reflected in increased disease rates in urbanizing and emigrant populations. Public health policies need to benefit metabolic capacity without exacerbating metabolic load.

Abstract
The growth status of Mozambique adolescents was assessed to test the hypothesis that relative leg length is a more sensitive indicator of the quality of the environment than the total height. The sample comprised 690 boys and 727 girls, aged between 9 and 17 years, from Maputo. It is divided between those living in the Centre of Maputo and those living in the slums on the periphery of the city. Height, weight, and sitting height were measured and the sitting height ratio was calculated. The hypothesis that relative leg length is more sensitive than total stature as an indicator of environmental quality is not uniformly confirmed. Overall, mean stature is greater for the centre group than the slum group, but relative leg length as measured by the sitting height ratio does not differ. Compared with African-American references (NHANES II), all centre girls, 9- to 14-year-old slum girls, all slum boys, and the oldest centre boys show relatively shorter legs. These findings show that within the Mozambique sample, relative leg length is not sensitive enough to distinguish the quality of the living environment. Mozambique was a colony of Portugal until 1975. Civil unrest and warfare characterized the late Colonial period and the postindependence period until a peace settlement was concluded in 1992. It is possible that all socioeconomic status groups within the country suffered sufficiently to reduce relative leg length compared with the better-off African-American reference sample. Possible genetic influences on relative leg length are also discussed.

Abstract
CONTEXT Prior research on the determinants of child health has focused on contemporaneous risk factors such as maternal behaviors, dietary factors, and immediate environmental conditions. Research on intergenerational factors that might also predispose a child to increased health adversity remains limited. OBJECTIVE To examine the association between maternal height and child mortality, anthropometric failure, and anemia. DESIGN, SETTING, AND POPULATION We retrieved data from the 2005-2006 National Family Health Survey in India (released in 2008). The study population constitutes a nationally representative cross-sectional sample of singleton children aged 0 to 59 months and born after January 2000 or January 2001 (n = 50 750) to mothers aged 15 to 49 years from all 29 states of India. Information on children was obtained by a face-to-face interview with mothers, with a response rate of 94.5%. Height was measured with an adjustable measuring board calibrated in millimeters. Demographic and socioeconomic variables were considered as covariates. Modified Poisson regression models that account for multistage survey design and sampling weights were estimated. MAIN OUTCOME MEASURES Mortality was the primary end point; underweight, stunting, wasting, and anemia were included as secondary outcomes. RESULTS In adjusted models, a 1-cm increase in maternal height was associated with a decreased risk of child mortality (relative risk [RR], 0.978; 95% confidence interval [CI], 0.970-0.987; P < .001), underweight (RR, 0.971; 95% CI, 0.968-0.974; P < .001), stunting (RR, 0.971; 95% CI, 0.968-0.0973; P < .001), wasting (RR, 0.989; 95% CI, 0.984-0.994; P < .001), and anemia (RR, 0.998; 95% CI, 0.997-0.999; P = .02). Children born to mothers who were less than 145 cm in height were 1.71 times more likely to die (95% CI, 1.37-2.13) (absolute probability, 0.09; 95% CI, 0.07-0.12) compared with mothers who were at least 160 cm in height (absolute probability, 0.05; 95% CI, 0.04-0.07). Similar patterns were observed for anthropometric failure related to underweight and stunting. Paternal height was not associated with child mortality or anemia but was associated with child anthropometric failure. CONCLUSION In a nationally representative sample of households in India, maternal height was inversely associated with child mortality and anthropometric failure.

Abstract
Background Some studies suggest that weight gain in childhood may increase the risk of chronic diseases in adulthood, and recent studies have noticed that the timing of weight gain may be related to its long-term consequence. However, weight gain in childhood has clear short-term benefits, and the literature on the pro and cons of weight gain in childhood is limited. Methods In 1982, all 5914 hospital births (over 99% of all deliveries) occurring in Pelotas, Southern Brazil, were identified and studied prospectively on several occasions. In 2004–05, we attempted to trace the whole cohort and information on offspring birthweight was collected. Conditional growth modelling was used to assess the association between offspring birthweight and weight gain from birth to 20 months, and from 20 to 42 months. Results In 2004–05, we interviewed 4297 subjects, with a follow-up rate of 77.4%. This manuscript includes data from 848 women who had already delivered a child and 525 men who were fathers at the mean age of 23 years. Maternal birthweight, weight and length for age Z-score at 20 months of age were positively associated with next-generation birthweight, whereas paternal variables were not related to the outcome. Conditional growth modelling analyses showed that women whose weight gain in the first 20 months of life was faster than predicted had heavier babies, whereas paternal weight gain was not associated. The association was strongest for mothers whose birthweight for gestational age was in the lowest tertile. Conclusion Maternal, but not paternal birthweight and weight gain in early childhood are positively associated with next-generation birthweight.

Abstract
BACKGROUND Singleton children born after IVF are of lower birthweight compared with their naturally conceived peers. It has been hypothesized that ovarian stimulation might be associated with low birthweight in children born after IVF. The aim of the present study was to explore whether or not a dose relationship exists between ovarian stimulation and birthweight in singletons born after ovarian stimulation for IVF. METHODS Using a national IVF registry database with a coverage of 65-70%, parental demographic variables, treatment cycle variables and neonatal variables were retrieved from all IVF treatment cycles in women between 25 and 35 years of age in which gonadotrophins were used for ovarian stimulation and a fresh embryo transfer resulting in singleton live birth was performed. Birthweight was standardized as a z-score, adjusting for gestational week at delivery and fetal sex, using data from a large reference population. Multivariate regression analysis was used to investigate the association between the dependent variable z-score and the independent predictor variables maternal age (years), maternal weight (kg), maternal height (cm), maternal body mass index (BMI) (kg/m(2)), duration of infertility (years), number of embryos transferred (n), duration of stimulation (days), consumption of gonadotrophins (ampoules) and number of oocytes retrieved (n). RESULTS Data retrieval yielded 32,416 singleton live births after IVF, with a mean (+/-SD) z-score of -0.25 (+/-1.0) and -0.23 (+/-1.0) for male and female neonates, respectively. Regression analysis indicated that maternal weight, maternal height, duration of infertility and the number of embryos transferred were statistically significant determinants of the birthweight of singletons after ovarian stimulation IVF. Parameters of ovarian stimulation (duration of stimulation, consumption of gonadotrophins, number of oocytes retrieved), maternal BMI and maternal age did not significantly predict birthweight. CONCLUSIONS Features reflecting ovarian stimulation do not correlate with birthweight. Therefore, ovarian stimulation is unlikely to be a factor affecting birthweight of IVF pregnancies.

Abstract
BACKGROUND Previous studies provided conflicting results on the relevance of parental characteristics for offspring's size at birth. The objective of this study was to investigate parental predictors of birthweight. METHODS In this cross-sectional study, 34,063 women in the Nurses' Mother's Cohort were queried about parental characteristics during the pregnancy with and birthweight of their nurse daughter. RESULTS The predictive linear regression model of birthweight included 13 factors and the majority of the predictive power came from parental anthropometric factors. In the adjusted analysis, daily consumption of each additional glass of milk was associated with an increase of approximately 6 g in birthweight (P for trend = 0.01) and daily consumption of each additional cup of coffee was associated with a decrease of approximately 10 g in birthweight (P for trend < 0.0001). Drinking 1-2, 3-4 and 5+ cups of coffee daily was associated with a 28% [95% confidence interval (CI) 0.12, 0.47], 30% (95% CI 0.10, 0.55) and 63% (95% CI 0.25, 1.12) increase, respectively, in the odds of intrauterine growth restriction when compared with non-drinkers. CONCLUSIONS The present study confirmed several previously reported determinants of birthweight. Maternal dietary intake of milk and coffee during pregnancy may influence fetal growth.

Abstract
Human beings growing-up in adverse biocultural environments, including undernutrition, exposure to infection, economic oppression/poverty, heavy workloads, high altitude, war, racism, and religious/ethnic oppression, may be stunted, have asymmetric body proportions, be wasted, be overweight, and be at greater risk for disease. One group of researchers explains this as a consequence of "developmental programming" (DP). Another group uses the phrase "predictive adaptive response" (PAR). The DP group tends to view the alterations as having permanent maladaptive effects that place people at risk for disease. The PAR group considers the alterations at two levels of adaptation: (1) "short-term adaptive responses for immediate survival" and (2) "predictive responses required to ensure postnatal survival to reproductive age." The differences between the DP and PAR hypotheses are evaluated in this article. A life history theory analysis rephrases the DP versus PAR debate from disease or adaptation to the concept of "trade-offs." Even under good conditions, the stages of human life history are replete with trade-offs for survival, productivity, and reproduction. Under adverse conditions, trade-offs result in reduced survival, poor growth, constraints on physical activity, and poor reproductive outcomes. Models of human development may need to be refined to accommodate a greater range of the biological and cultural sources of adversity as well as their independent and interactive influences.

Abstract
There is now much evidence that early life undernutrition elevates risk of diseases like cardiovascular disease. Less clear is whether the underlying developmental plasticity in metabolism and physiology evolved to serve an adaptive function, beyond these effects on pathophysiology. This review builds from principles of life history theory to propose a functional model linking early environments with adult biology. An organism has metabolic potential in excess of survival requirements, called productivity, that supports growth before being shunted into reproduction after growth ceases. This concept from inter-specific studies leads to the prediction that plasticity in growth rate will be positively correlated with components of future adult reproductive expenditure. Consistent with this idea, evidence is reviewed that early nutrition or growth rate predict offspring size in females, and increased somatic investment related to reproductive strategy in males. Thus, population birth weight and sexual size dimorphism are predicted to increase in response to improvements in early nutrition. A striking feature of the continuity of metabolic production is its perpetuation not merely during the lifecycle but across generations: in females, growth rate predicts future nutritional investment in reproduction, which in turn determines fetal growth rate in the next generation. Growth and reproduction serve as mutually-defining templates, thus creating a phenotypic bridge allowing ecologic information to be maintained during ontogeny and transmitted to offspring. Resetting of metabolic production in response to maternal nutritional cues may serve a broader goal of integrating nutritional information within the matriline, thus providing a more reliable basis for adjusting long-term strategy.

Abstract
BACKGROUND Parental weight and height correlate with offspring birthweight and weight gain, suggesting genetic and environmental influences on fetal growth. The differential contributions of the mother's and father's height and weight to birthweight, or weight gain in infancy, remain unclear and were examined using data from the UK Millennium Cohort Study. METHODS We calculated z-scores for birthweight and conditional weight gain to age 9 months (weight gain adjusted for birthweight) for 6811 term white singleton infants living with natural parents, using the British 1990 growth reference. We also calculated parental height and weight z-scores. The effects of parental size on birthweight and weight gain were analysed using multivariable regression, with a novel reparameterization to test for differences in effect size between mother and father. RESULTS Maternal weight had a far greater influence than paternal weight on birthweight [coefficient for the difference between parents (95% CI): 0.15 (0.100.20)], while parental height contributions were similar [0.03 (-0.02 to 0.07)]. Weights and heights of mothers and fathers contributed equally to infant weight gain [difference coefficients -0.03 (-0.09 to 0.02) and 0.02 (-0.03 to 0.07), respectively]. CONCLUSIONS The influences of parental height and weight on birthweight and infant weight gain are similar for the two parents, with the exception of the influence of weight on birthweight where the mother is much more influential than the father. Parental size associations with infant growth result from a complex combination of genetic and environmental influences. This novel reparameterization of parental anthropometry is applicable to other studies examining parental influences on offspring size and growth across the life course.

Abstract
The aim of this study is to investigate how maternal childhood and adulthood social class contribute to social inequalities in low birth weight, neonatal mortality and postneonatal mortality. In particular I consider the combined influence of childhood and adult class, and compare outcomes with regard to the time distance from birth. Analyses were performed on a large sample of Swedish births from 1973 to 1990, restricted to infants of women with both childhood and adult class, classified as manual or non-manual. Logistic regression is used to compare odds ratios for social classes. The results indicate that manual maternal childhood class is consistently associated with higher risks for low birth weight and neonatal mortality, even when adult class was adjusted for. The influence of adult class was greater than that of childhood class for all health outcomes. Compared to higher/middle non-manual workers, unskilled workers in the service sector and workers in the manufacturing sector displayed the highest odds ratios for all adverse health outcomes. When both childhood and adult class were taken into account, social differences were greater for low birth weight and neonatal mortality than for postneonatal mortality. Maternal childhood class had more influence on low birth weight and neonatal mortality than on postneonatal mortality. I conclude that maternal childhood and adulthood social class are both independently associated with inequalities in health-related birth outcomes, and that social differences are greater for health outcomes closer to birth.

Abstract
When birth weight for gestation is used as a surrogate for intrauterine growth, the prevalence of cerebral palsy varies continuously in a reversed J shape, with steep increases in the risk for infants lighter and heavier than the optimum size. Patterns of size-at-birth specific risk for cerebral palsy differ between male and female infants, as do the patterns for more severe versus milder cases. Although these excess risks with abnormal size at birth imply antenatal precursors, it is not clear whether or how intrauterine growth is involved in any of the suspected causal pathways resulting in cerebral palsy. The implication for clinicians is that serial measures of in utero growth may provide an important indicator of fetal health.
