A woman in her 30s with a history of multiple bone fractures unexpectedly became pregnant and delivered a full-term baby through cesarean section, despite suffering from excruciating pain without any apparent cause or specific treatment. The patient was referred to our endocrine clinic following childbirth. Blood tests revealed a life-threatening low level of serum phosphate, normal 25-hydroxy vitamin D concentration, low TmP/GFR ratio, and elevated FGF23 levels. A PET/CT scan with Gallium-68 Dotatate identified an abnormal tumor in the right calcaneus. Her FGF23 level returned to normal soon after surgical removal of the tumor, which was confirmed to be chondroblastoma. Her child's cognitive and motor skills typically developed from the newborn to preschool age. He exhibited excellent long-term growth, without any signs of rickets. [ABSTRACT FROM AUTHOR]

Abstract Objective Skilled birth attendance and place of delivery have a significant effect on child growth. The present paper examined the mode of delivery and its impact on child health among children 0–59 months in India. Methods A total of 200,794 samples were used in the study. Among them, 45,784 births were delivered by C-section, and the remaining 150,010 births were delivered through normal delivery. Life table estimation of mortality, as well as bivariate and multivariate logistic regression, were used to identify the association between child health and mode of delivery using data from the fifth round of the National Family Health Survey conducted in 2019-21. Results The study results indicate that children born through normal delivery had significantly lower rates of stunting, wasting, and underweight compared to those born via C-section. Additionally, the likelihood of a new-born baby dying during the neonatal period was higher for those delivered by C-section compared to those delivered vaginally, which holds true for various background characteristics. Mothers with a 3rd or higher order birth who deliver via C-section face a higher risk of their baby dying during the neonatal and infant periods compared to those with a 2nd order birth. Conclusion The conclusion of the study found that C-section delivery may adversely affect child undernutrition as compared to normal birth. These findings would help formulate the policies and implement actions that would improve the quality of painless labor and immediate delivery in health facilities particularly public hospitals and shall reduce the C-section birth.

Background: Lack of nutritional intake is a significant factor causing stunting in children, affecting their growth and development. The role of maternal knowledge and parenting practices is crucial in preventing stunting. Objective: In This study aims to determine the relationship between maternal knowledge and stunting in toddlers in Forestry Hamlet, Secanggang Village, Langkat Regency. Methods: A descriptive quantitative research design was employed. Data were collected using questionnaires from a sample of 30 mothers of toddlers. The study analyzed the knowledge levels of these mothers regarding stunting. Results: The analysis revealed that 70% of mothers had good knowledge, 26.7% had sufficient knowledge, and 3.3% had poor knowledge about stunting. The findings suggest that higher education levels among mothers are associated with better knowledge about preventing stunting. Conclusion: There is a significant relationship between maternal knowledge and the incidence of stunting in toddlers. Enhancing health education and promoting better understanding of toddler nutrition among mothers can contribute to reducing stunting rates. Health services and authorities should focus on disseminating information through various media to improve maternal knowledge and practices related to child nutrition.

Abstract Evidence suggests that maternal metabolome may be associated with child health outcomes. We analyzed the association between the maternal metabolome between 28–35 gestational weeks and child growth and development during the first year. A prospective cohort of 98 mother–child dyads was followed at birth, 1, 6, and 12 months. Maternal serum samples were collected for targeted LC–MS/MS analysis, which measured 132 metabolites. The child's growth and development were assessed at each time-point. Z-scores were calculated based on WHO growth standards, and the domains of development were assessed using the Ages and Stages Questionnaires (ASQ-3). Multiple linear mixed-effects models were performed and confounders were identified using a Diagram Acyclic Graph. The Benjamini–Hochberg correction was used for multiple comparison adjustments. We found a positive association between lysophosphatidylcholines (14:0; 16:0; 16:1; 17:0; 18:0; 18:1; 18:2; 20:4) with the z-score of weight-for-age, and lysophosphatidylcholines (14:0; 16:0; 16:1; 18:0) and taurine with the z-score of weight-for-length, and lysophosphatidylcholines (14:0; 16:0; 16:1; 17:0; 18:0; 18:1; 18:2; 20:4) and glycine with the z-score of BMI-for-age. The leucine, methionine, tryptophan, and valine were negatively associated with the fine motor skills domain. We observed an association between maternal metabolome and the growth and child's development throughout the first year.

Poor sanitation may be associated with growth faltering, but empirical evidence on the association between household sanitation infrastructure and child nutrition has been mixed. This article assessed whether sanitation infrastructure is associated with growth penalties for Roma children.

Poor diet quality (diet diversity and animal‐source food [ASF] consumption) during childhood negatively affects growth, development, behaviour and physiologic function in later life. Relatively less is known about the impact of poor diet on the growth of school‐age children compared to children <5 years of age, especially in low/middle‐income countries. A better understanding of delivery strategies for effective interventions to improve diet and hence growth in school‐age children is needed. A 36‐month longitudinal controlled impact evaluation in rural Nepal assessed the nutrition and growth of children <5 years of age in families assigned via community clusters to full package intervention (community development, training in nutrition [during pregnancy and for children <5 years] and livestock husbandry), partial package (training only) or control (no inputs). Concurrent data were collected prospectively (baseline plus additional four rounds) on school‐age children (5–8 years at baseline) in these households; the present study analysed findings in the cohort of school‐age children seen at all five study visits (n = 341). Diet quality improved more in the full package school‐age children compared to those in partial package or control households. full package children consumed more ASF (β +0.40 [CI 0.07,0.73], p < 0.05), more diverse diets (β +0.93 [CI 0.55,1.31], p < 0.001) and had better head circumference z‐scores (β +0.21 [CI 0.07,0.35], p < 0.01) than control children. In conclusion, a multi‐sectoral community development intervention was associated with improvements in diet and growth of school‐age children in rural Nepal even though the intervention focused on the diet of children <5 years of age. The diet and growth of school‐age children can be favourably influenced by community‐level interventions, even indirectly. Key messages: Relatively less is known about the factors that influence diet quality and growth in school‐age children compared to younger children, especially in low‐ and middle‐income countries.Better diet quality and growth were found among school‐age children whose families participated in an impact study multi‐sectoral intervention compared to children in control families or those whose families only received nutrition training.Diet and growth of school‐age children can be favourably influenced by community‐level interventions.

Aim: How maternal opioid maintenance treatment (OMT) affects children is under‐researched. This population‐based registry study investigated child growth and somatic health following intrauterine exposure to this treatment. Methods: Children born between 1 March 2011 and 30 May 2021 to mothers who used buprenorphine, buprenorphine‐naloxone, or methadone throughout their pregnancies were followed for 2 years at the Helsinki University Hospital, Finland. Appropriate statistical tests were used to compare the treatment groups. Results: Of the 67 neonates, 52% were male, 96% were born full‐term and 63% were treated for neonatal opioid withdrawal syndrome. Otherwise, the children were predominantly healthy, although relatively small: 22% were small for gestational age, the methadone group children being the smallest. Foetal exposure to maternal methadone treatment, illicit drugs, hepatitis C and smoking were associated with small for gestational age; the former two were also associated with later slower growth, especially head growth and weight gain (p < 0.001). However, 29% were overweight at 2 years. Conclusion: Using child growth as the outcome, we found that buprenorphine‐naloxone and buprenorphine‐monotherapy had equal effects as forms of maternal OMT. Exposure to multiple risk factors may harm foetal and subsequent growth. We recommend long‐term follow‐up of children exposed to maternal OMT. [ABSTRACT FROM AUTHOR]

BackgroundAflatoxin (AF) exposure is associated with child growth faltering in cross-sectional studies, with limited findings from longitudinal studies.ObjectivesTo evaluate the relationship between maternal AF B1-lysine adduct concentration, child AF B1-lysine adduct concentration, and child growth in the first 30 mo of life.MethodsAF B1-lysine adduct was measured in mother-child dyad plasma samples using isotope dilution mass spectrometry. Using linear regression, we assessed the relationship between AF B1-lysine adduct concentration and child weight, height, and head and mid-upper arm circumferences at 1 wk, 6, 12, 18, 24, and 30 mo of age.ResultsIn adjusted models, maternal prenatal AF B1-lysine adduct (pg/μL) was positively associated with newborn anthropometric outcomes; largest beta coefficients for associations between standardized values were for newborn weight-for-age z-score [β = 0.13; 95% confidence interval (CI): 0.02, 0.24; P < 0.05 and β = 0.11; 95% CI: 0.00, 0.22; P < 0.05 for second and third trimester AF, respectively]. Child AF B1-lysine adduct (pg/μL) at 6 mo was negatively associated with head circumference-for-age z-score at 6, 18, 24, and 30 mo, with beta coefficients ranging from β = -0.15; 95% CI: -0.28, -0.02 to β = -0.17; 95% CI: -0.31, -0.03; P < 0.05); 18-mo AF was negatively associated with anthropometric outcomes at 18, 24, and 30 mo, most consistently with length-for-age z-score (β = -0.18; 95% CI: -0.32, -0.04, β = -0.21; 95% CI: -0.35, -0.07, β = -0.18; 95% CI: -0.32, -0.03 at 18, 24 and 30 mo, respectively).ConclusionsChild AF exposure was associated with impaired child growth, but maternal AF exposure was not. Exposure during infancy was linked to persistent deficit in head circumference, implying reduced brain size lasting beyond the age of 2 years. Exposure at 18 mo was linked to persistent linear growth deficit. Further research should elucidate mechanisms through which AF affects child growth.

Background Child stunting is a significant challenge for most districts in Rwanda and much of sub-Saharan Africa and persists despite multisectoral efforts. There is a notable lack of population-based studies examining the correlation between violence against women and child stunting in Rwanda. Objective We aimed to investigate the association between Rwandan women’s exposure to intimate partner violence (IPV) and child stunting in children under 3 years of age. Methods In December 2021, a population-based cross-sectional study was conducted in the Northern Province of Rwanda, including 601 women and their children

Background Chewing betel quid (BQ) – a preparation commonly containing areca nut and slaked lime wrapped in betel leaf – is entrenched in South Asia. Although BQ consumption during pregnancy has been linked to adverse birth outcomes, its effect on postnatal growth remains largely unexplored. Objective We examined the associations of BQ use during pregnancy with children’s height-for-age and body mass index-for-age z-scores (HAZ and BAZ, respectively) and fat and fat-free mass along with sex-based differences in association in rural Bangladesh. Methods With a prospective cohort design, we assessed BQ use among mothers enrolled in the Preterm and Stillbirth Study, Matlab (n = 3140) with a structured questionnaire around early third trimester. Children born to a subset of 614 women (including 134 daily users) were invited to follow-up between October 2021 and January 2022. HAZ and BAZ were calculated from anthropometric assessment, and fat and fat-free mass were estimated using bioelectric impedance. Overall and sex-specific multiple linear regression models were fitted. Results Growth data were available for 501 children (mean age 4.9 years): 43.3% of them were born to non-users, 35.3% to those using prior to or less-than-daily during the survey, and 21.3% to daily users. No statistically significant associations were observed after adjusting for sex, parity, maternal height and education, and household wealth. Conclusions There was no effect of BQ use during pregnancy on postnatal growth in this study. Longitudinal studies following up those born to heavy users beyond childhood are warranted for capturing long-term implications of prenatal BQ exposure.

Summary: Background: Intermittent preventive treatment for malaria in pregnancy (IPTp) can improve birth outcomes, but whether it confers benefits to postnatal growth is unclear. We investigated the effect of IPTp on infant growth in Uganda and its pathways of effects using causal mediation analyses. Methods: We analysed data from 633 infants born to mothers enrolled in a randomised trial of monthly IPTp with dihydroartemisinin-piperaquine (DP) vs. sulfadoxine-pyrimethamine (SP) (NCT02793622). Weight and length were measured from 0 to 12 months of age. Using generalised linear models, we estimated effects of DP vs. SP on gravidity-stratified mean length-for-age (LAZ) and weight-for-length Z-scores (WLZ). We investigated mediation by placental malaria, gestational weight change, maternal anaemia, maternal inflammation-related proteins, preterm birth, birth length, and birth weight. Mediation models adjusted for infant sex, gravidity, gestational age at enrolment, maternal age, maternal parasitaemia at enrolment, education, and wealth. Findings: SP increased mean LAZ by 0.18–0.28 Z from birth through age 4 months compared to DP, while DP increased mean WLZ by 0.11–0.28 Z from 2 to 8 months compared to SP among infants of multigravidae; at these ages, confidence intervals for mean differences excluded 0. We did not observe differences among primigravida. Mediators of SP included birth weight, birth length, maternal stem cell factor, and DNER. Mediators of DP included placental malaria and birth length, maternal IL-18, CDCP1, and CD6 at delivery. Interpretation: In high malaria transmission settings, this exploratory study suggests different IPTp regimens may influence infant growth among multigravidae, potentially through distinct pathways, in the exclusive breastfeeding period, when few other interventions are available.

The Task Force "Towards a Multidimensional Index to Child Growth", within the International Union of Nutritional Sciences, developed a capability framework for child growth (CFCG). This framework aims to redefine child growth monitoring, expanding beyond weight and height to encompass parental capabilities. We further operationalised the CFCG in hard-to-reach haor areas of Bangladesh, resulting in the publication of a list outlining parental capabilities for child growth. This paper details the methodology and participatory process employed, offering reflections on how our research followed the criteria proposed by Robeyns for identifying capabilities. First, we built a contextualised list of capabilities for child growth based on discussions with local experts. This list underwent further adaptation for haor regions in two rounds. Initially, we used a doxastic interviewing methodology to create a draft emic list of capabilities for child growth. Subsequently, utilising an epistemic methodology, we refined the list. The doxastic interviews focused on "understanding" the interviewees; the epistemic interviews facilitated equal communication between interviewer and interviewee, promoting knowledge co-creation. This rigorous approach validates the findings with the affected communities and supports implementation of the CFCG in policy and practice. This methodology could be extended to other pertinent research areas for capability scholars. [ABSTRACT FROM AUTHOR]

Background: Preterm infants often have poor short‐ and long‐term growth. Kangaroo mother care supports short‐term growth, but longer‐term outcomes are unclear. Methods: This study analysed longitudinally collected routine clinical data from a South African cohort of preterm infants (born <37 weeks gestation) attending the outpatient follow‐up clinic of a tertiary‐level hospital (Tshwane District, South Africa) for 1 year between 2012 and 2019. At 1 year, small‐for‐gestational age (SGA) and appropriate‐for‐gestational age (AGA) infants were compared with regard to age‐corrected anthropometric z‐scores (weight‐for‐age [WAZ], length‐for‐age [LAZ], weight‐for‐length [WLZ] and BMI‐for‐age [BMIZ]) and rates of underweight (WAZ < −2), stunting (LAZ < −2), wasting (WLZ < −2) and overweight (BMIZ> + 2). Multiple regression analysis was used to investigate associations between maternal/infant characteristics and rates of underweight, stunting, wasting and overweight. Results: At 1 year, compared with AGA infants (n = 210), SGA infants (n = 111) had lower WAZ (−1.26 ± 1.32 vs. −0.22 ± 1.24, p < 0.001), LAZ (−1.50 ± 1.11 vs. −0.60 ± 1.06, p < 0.001), WLZ (−0.66 ± 1.31 vs. 0.11 ± 1.24, p < 0.001) and BMIZ (−0.55 ± 1.31 vs. 1.06 ± 1.23, p < 0.001), despite larger WAZ gains from birth (+0.70 ± 1.30 vs. +0.05 ± 1.30, p < 0.001). SGA infants had significantly more stunting (34.2% vs. 9.1%; p < 0.001), underweight (31.2% vs. 7.2%; p < 0.001) and wasting (12.6% vs. 4.3%, p = 0.012), with no difference in overweight (4.5% vs. 7.7%, p = 0.397). In multiple regression analysis, birth weight‐for‐GA z‐score more consistently predicted 1‐year malnutrition than SGA. Conclusion: Preterm‐born SGA infants remain more underweight, stunted and wasted than their preterm‐born AGA peers at 1 year, despite greater WAZ gains. Interventions for appropriate catch‐up growth especially for SGA preterm infants are needed. [ABSTRACT FROM AUTHOR]

Background: Concurrent losses in biodiversity and human dietary diversity are evident in Madagascar and across many food systems globally. Wild food harvest can mitigate nutrition insecurities but may also pose species conservation concerns. Objectives: This study aimed to examine the association of wild plant and animal species consumption during hunger season with diet diversity and child growth near the Alandraza-Agnalavelo protected forest in Southwestern Madagascar. Second, we studied the conservation status of the consumed wild plants. Methods: Methods from public health nutrition (24-h recall dietary intake, anthropometry using World Health Organization [WHO] Growth Standards), ethnobotany, and forest ecology (ecologic studies of abundance, habitat preference, associated species, food chemistry assays, and species richness) were applied. Results: Malnutrition in children (n = 305) was highly prevalent: stunting (32.3%); wasting (18.8%); and low-dietary diversity (4% meeting WHO minimum dietary diversity threshold). Animal foods were consumed in small quantities, providing <10% of Dietary Reference Intakes for all limiting nutrients. Twenty-two wild plant species were consumed during hunger season, prominently tubers (Dioscoreaceae), and leafy greens (Asteraceae, Blechnaceae, Portulacaceae, and Solanaceae). Eight of the 9 target species were identified as abundant and "Least Concern," whereas Amorphophollus taurostigma was abundant and "Vulnerable." Regression modeling showed wild food consumption was associated with an increased household dietary diversity score [β = 0.29 (0.06 standard error); P < 0.001], and total wild animal foods positively correlated with height-for-age Z score [β = 0.14 (0.07 standard error); P = 0.04]. Conclusions: Wild plant and animal foods may be an important element of food systems to support human nutrition while maintaining ecosystem viability. [ABSTRACT FROM AUTHOR]

Background: Exclusive breastfeeding is one of the major requirements for a balanced child’s health and brain development. It provides essential nutrients, antibodies, and other bioactive components that shield infants from infections and diseases. Despite the numerous benefits, the practice remains sub-optimal in many parts of Nigeria, including Enugu urban. Objective: This study investigated how radio advocacy programmes influence the knowledge and practice of exclusive breastfeeding among working-class nursing mothers in Enugu, Nigeria. Method: Adopting descriptive survey research design, 380 working-class nursing mothers residing in Enugu urban were sampled using a multistage sampling technique. The participants were selected from the three local government areas that make up the urban area of Enugu State. The LGAs were Enugu-North, Enugu-South, and Enugu-East. Data were collected using a structured questionnaire with a consistency coefficient of 0.95, while analysis was done using descriptive statistics and presented using frequency tables. Results: There was high level of exposed to radio programmes on exclusive breastfeeding among participants, but could not yield the desired attitude and behaviour changes for adherence to the practice due to other variables such as culture, modernisation, and peer influence. Conclusion: The study concludes that the majority of working-class nursing mothers in the Enugu urban area do not practise exclusive breastfeeding, despite the high level of exposure to radio advocacy programmes on the subject matter. This could be attributed to the nuanced interplay of influences of other key stakeholders in infants’ breastfeeding decisions and some socio-cultural inhibitors, such as modernisation, pre-existing misconceptions and the quest to retain breast aesthetics. Unique Contribution: This study has offered new insight into the increasing influence of intervening variables on the effects of media on the audience. Hopefully, policymakers, healthcare practitioners, and communication experts will find this fresh insight useful in planning future advocacy programmes on exclusive breastfeeding among urban-based nursing mothers. Key Recommendation: Comprehensive community-based policies and cohesive intervention programmes that involve regular (re)orientation of not just nursing mothers but all key stakeholders in infants’ breastfeeding decisions, such as mothers, grandmothers, husbands, caregivers, traditional birth attendants (TBAs), mothers-in-law, and religious leaders, are required to implement EBF among working-class nursing mothers.

Abstract Poor diet quality (diet diversity and animal‐source food [ASF] consumption) during childhood negatively affects growth, development, behaviour and physiologic function in later life. Relatively less is known about the impact of poor diet on the growth of school‐age children compared to children

STUDY QUESTION Are there growth differences between singleton children born after frozen embryo transfer (FET), fresh embryo transfer (ET), and natural conception (NC)? SUMMARY ANSWER Adolescent boys born after FET have a higher mean proportion and increased odds of overweight compared to those born after fresh ET. WHAT IS KNOWN ALREADY Children born after FET have higher mean birthweights and an increased risk of large-for-gestational-age compared to those born after fresh ET and even NC. This raises questions about possible growth differences later in childhood. Previous studies on child growth after FET report partly conflicting results and lack long-term data until adolescence. STUDY DESIGN, SIZE, DURATION This was a cohort study based on national population-based registers, the Finnish Medical Birth Register and the Register of Primary Health Care visits, including singletons born after FET (n = 1825), fresh ET (n = 2933), and NC (n = 31 136) in Finland between the years 1995 and 2006. PARTICIPANTS/MATERIALS, SETTING, METHODS The proportions of overweight (i.e. age- and sex-adjusted ISO-BMI for children ≥ 25) were compared between the groups. Odds ratios (ORs) and adjusted odds ratios (aORs) of overweight were calculated. Adjustments were made for birth year, preterm birth, maternal age, parity, and socioeconomic status. Mean heights, weights, and BMIs were compared between the groups each year between the ages of 7 and 18. MAIN RESULTS AND THE ROLE OF CHANCE FET boys had a higher mean proportion of overweight (28%) compared to fresh ET (22%, P  < 0.001) and NC (26%, P  = 0.014) boys. For all ages combined, the aOR of overweight was increased (1.14, 95% CI 1.02–1.27) for FET boys compared to fresh ET boys. For girls, the mean proportions of overweight were 18%, 19%, and 22% for those born after FET, fresh ET, and NC, respectively (P  = 0.169 for FET vs fresh ET, P  < 0.001 for FET vs NC). For all ages combined, FET girls had a decreased aOR of overweight (0.89, 95% CI 0.80–0.99) compared to NC girls. Growth measurements were available for 6.9% to 30.6% of FET boys and for 4.7% to 29.4% of FET girls at different ages. LIMITATIONS, REASONS FOR CAUTION Unfortunately, we were not able to adjust for parental anthropometric characteristics. The growth data were not available for the whole cohort, and the proportion of children with available measurements was limited at the start and end of the follow-up. During the study period, mainly cleavage stage embryos were transferred, and slow freezing was used for ART. WIDER IMPLICATIONS OF THE FINDINGS The risk of overweight among FET boys warrants further research. Future studies should aim to investigate the mechanisms that explain this sex-specific finding and combine growth data with long-term health data to explore the possible risks of overweight and cardiometabolic disease in adulthood. STUDY FUNDING/COMPETING INTEREST(S) Funding was obtained from the Päivikki and Sakari Sohlberg Foundation, the Alma and K.A. Snellman Foundation (personal grants to A.M.T.), and the Finnish Government Research Funding. The funding sources were not involved in the planning or execution of the study.

Background: Parental influences on children's eating and physical activity (PA) and consequently on their weight are fundamental. The present study aimed to identify the predominant correlates of childhood overweight/obesity among a variety of parental practices and children's lifestyle indices in a large sample of children in Europe. Methods: Families from low socio‐economic status regions were recruited through schools, located in six European countries (Belgium, Finland, Greece, Spain, Bulgaria and Hungary). Seven thousand three hundred ninety‐seven children 4–12 years old and their parents were selected using the FINDRISC‐questionnaire. Parental practices assessed included parental role modelling, permissiveness and reward. Children's dietary intake and lifestyle behaviours were assessed through parent‐reported questionnaires. Results: Regarding parental practices, it was revealed that being sometimes (odds ratio [OR] = 1.26; 95% confidence interval [CI] = 1.10–1.43) or rarely (OR = 1.43; 95% CI = 1.21–1.69) physically active with the child was associated with greater overweight/obesity risk, whereas rare permission of computer/mobile/tablet (OR = 0.81; 95% CI = 0.67–0.98) and sometimes (OR = 0.77; 95% CI = 0.68–0.88) or rare (OR = 0.77; 95% CI = 0.66–0.91) reward with PA were associated with lower risk. Regarding children's lifestyle factors, consuming > 3 cups/week fresh fruit juices (OR = 1.28; 95% CI = 1.13–1.45), skipping breakfast (OR = 1.37; 95% CI = 1.17–1.61), absence of 1 h of daily PA (OR = 1.40; 95% CI = 1.24–1.58) and increased daily screen time (ST) (OR = 1.23; 95% CI = 1.09–1.39) were associated with greater overweight/obesity risk. All the variables were adjusted for maternal education, child's sex and age. Conclusions: These findings emphasize the necessity of family‐centered approaches in health promotion and obesity prevention programs for children. Such programs should focus on parents as the primary role models in exerting positive influence and encouraging healthy eating habits, PA, and ST behaviors in their children, which in turn, may have a substantial impact on children's overall weight status. Key points: Being physically active with the child is associated with reduced obesity riskOmission of breakfast and high fresh fruit juices consumption may increase childhood obesity riskParental control on children's screen time is linked with lower childhood obesity risk [ABSTRACT FROM AUTHOR]

Summary: Background: The first 1000 days of life are critical for a child's health and development. Impaired growth during this period is linked to increased child morbidity, mortality, and long-term consequences. Undernutrition is the main cause, and addressing it within the first 1000 days of life is vital. Maternal education is consistently identified as a significant predictor of child undernutrition, but its specific impact remains to be determined. This study presents a systematic review and meta-analysis investigating the influence of high versus low maternal education levels on child growth from birth to age two, using population-based cohort studies. Methods: Databases including PubMed, Scopus, EMBASE, Web of Science, ERIC, and Google Scholar were searched from January 1990 to January 2024 using appropriate search terms. We included population-based cohort studies of healthy children aged two years and under and their mothers, categorizing maternal education levels. Child growth and nutritional outcomes were assessed using various indicators. Two reviewers independently conducted data extraction and assessed study quality. The Newcastle Ottawa scale was utilized for quality assessment. Random-effects models were used for meta-analysis, and heterogeneity was assessed using the Cochrane Q and I2 statistic. Subgroup and sensitivity analyses were performed, and publication bias was evaluated. Findings: The literature search retrieved 14,295 titles, and after full-text screening of 639 reports, 35 studies were included, covering eight outcomes: weight for age z-score (WAZ), height for age z-score (HAZ), BMI for age z-scores (BMIZ), overweight, underweight, stunting, wasting, and rapid weight gain. In middle-income countries, higher maternal education is significantly associated with elevated WAZ (MD 0.398, 95% CI 0.301–0.496) and HAZ (MD 0.388, 95% CI 0.102–0.673) in children. Similarly, in studies with low-educated population, higher maternal education is significantly linked to increased WAZ (MD 0.186, 95% CI 0.078–0.294) and HAZ (0.200, 95% CI 0.036–0.365). However, in high-income and highly educated population, this association is either absent or reversed. In high-income countries, higher maternal education is associated with a non-significant lower BMI-Z (MD −0.028, 95% CI −0.061 to 0.006). Notably, this inverse association is statistically significant in low-educated populations (MD −0.045, 95% CI −0.079 to −0.011) but not in highly educated populations (MD 0.003, 95% CI −0.093 to 0.098). Interpretation: Maternal education's association with child growth varies based on country income and education levels. Further research is needed to understand this relationship better.

Abstract Background The Developmental Origins of Health and Disease (DOHaD) paradigm emphasizes the significance of early life factors for the prevention of chronic health conditions, like type 2 diabetes (T2DM) and obesity, which disproportionately affect First Nations communities in Canada. Despite increasing DOHaD research related to maternal health during pregnancy, early childhood growth patterns, and infant feeding practices with many populations, data from First Nations communities in Canada are limited. In partnership with Sandy Lake First Nation, the aims of this project were to characterize birthweights and growth patterns of First Nations infants/children over the first 6 years of life and to study the impact of maternal and infant social and behavioral factors on birthweight and growth trajectories. Methods We recruited 194 families through community announcements and clinic visits. Infant/child length/height and weight were measured at 1 and 2 weeks; 1, 2, 6, 12, and 18 months; and 2, 3, 4, 5 and 6 years. Maternal and infant/child questionnaires captured data about health, nutrition, and social support. Weight-for-Age z-score (WAZ), Height-for-Age z-score (HAZ), and BMI-for-Age z-score (BAZ) were calculated using WHO reference standards and trajectories were analyzed using generalized additive models. Generalized estimating equations and logistic regression were used to determine associations between exposures and outcomes. Results WAZ and BAZ were above the WHO mean and increased with age until age 6 years. Generalized estimating equations indicated that WAZ was positively associated with age (0.152; 95% CI 0.014, 0.29), HAZ was positively associated with birthweight (0.155; 95% CI 0.035, 0.275), and BAZ was positively associated with caregiver’s BMI (0.049; 95% CI 0.004, 0.090). There was an increased odds of rapid weight gain (RWG) with exposure to gestational diabetes (OR: 7.47, 95% CI 1.68, 46.22). Almost 70% of parents initiated breastfeeding, and breastfeeding initiation was modestly associated with lower WAZ (-0.18; 95% CI -0.64, 0.28) and BAZ (-0.23; 95% CI -0.79, 0.34). Conclusions This work highlights early life factors that may contribute to T2DM etiology and can be used to support community and Indigenous-led prevention strategies.

Choline and DHA are nutrients that, when provided during the first 1000 days from conception to age 2 years, may have beneficial effects on child neurodevelopment as well as related health factors, including birth outcomes and child growth, morbidity, and inflammation. Because these nutrients are found mainly in animal-source foods, they may be lacking in the diets of pregnant and lactating women and young children in low- and middle-income countries, potentially putting children at risk for suboptimal development and health. Prior reviews of these nutrients have mainly focused on studies from high-income countries. Here, a narrative review is presented of studies describing the pre- and postnatal roles of choline, docosahexaenoic acid, and a combination of the 2 nutrients on child neurodevelopment, birth outcomes, growth, morbidity, and inflammation in low- and middle-income countries. More studies are needed to understand the specific, long-term effects of perinatal choline and docosahexaenoic acid intake in various contexts.

BackgroundImproved sanitation has been associated with improved child growth in observational studies, but multiple randomized trials that delivered improved sanitation found no effect on child growth. We assessed to what extent differences in the effect estimated in the two study designs (the effect of treatment in observational studies and the effect of treatment assignment in trials) could explain the contradictory results.MethodsWe used parametric g-computation in five prospective studies (n = 21 524) and 59 cross-sectional Demographic and Health Surveys (DHS; n = 158 439). We compared the average treatment effect (ATE) for improved sanitation on mean length-for-age z-score (LAZ) among children aged 0.15 z-scores, a clinically meaningful difference, in most prospective studies but in

IntroductionWe examined the scope of literature including non-parental caregiver involvement in child obesity prevention interventions.MethodsWe conducted a scoping review following the Arksey and O'Malley framework, including only studies reporting the effect of an intervention on growth, weight, or early childhood obesity risk among children ages 0 to three years, published between 2000 and 2021. Interventions that did not include non-parental caregivers (adults regularly involved in childcare other than parents) were excluded.ResultsOf the 14 studies that met the inclusion criteria, all were published between 2013 and 2020, and most interventions (n = 9) were implemented in the United States. Eight of the 14 interventions purposefully included other non-parental caregivers: five included both parents and non-parental caregivers, and the remaining three included only non-parental caregivers. Most interventions (n = 9) showed no significant impact on anthropometric outcomes. All interventions found improvements in at least one behavioral outcome (e.g., food groups intake (n = 5), parental feeding practices (n = 3), and screen time (n = 2)). This review can inform future interventions that plan to involve non-parental caregivers, which may be beneficial in shaping early health behaviors and preventing obesity early in life.

BackgroundIn lower resource settings, previous randomized controlled trials have demonstrated evidence of increased weight gain following antibiotic administration in children with acute illness. We conducted an individually randomized trial to assess whether single dose azithromycin treatment causes weight gain in a general population sample of children in Burkina Faso.MethodsChildren aged 8 days to 59 months were enrolled in November 2019 and followed through June 2020 in Nouna Town, Burkina Faso. Participants were randomly assigned to a single oral dose of azithromycin (20 mg/kg) or matching placebo. Anthropometric measurements were collected at baseline and 14 days and 6 months after enrollment. The primary anthropometric outcome was weight gain velocity in g/kg/day from baseline to 14 days and 6 months in separate linear regression models.ResultsOf 450 enrolled children, 230 were randomly assigned to azithromycin and 220 to placebo. Median age was 26 months (IQR 16 to 38 months) and 51% were female. At 14 days, children in the azithromycin arm gained a mean difference of 0.9 g/kg/day (95% CI 0.2 to 1.6 g/kg/day, P = 0.01) more than children in the placebo arm. There was no difference in weight gain velocity in children receiving azithromycin compared to placebo at 6 months (mean difference 0.04 g/kg/day, 95% CI - 0.05 to 0.13 g/kg/day, P = 0.46). There were no significant differences in other anthropometric outcomes.ConclusionsTransient increases in weight gain were observed after oral azithromycin treatment, which may provide short-term benefits.Clinical trials registrationClinicalTrials.gov NCT03676751 .

This study aims to provide an understanding of the importance of vitamins and minerals, as well as foods and drinks containing vitamins and minerals according to age. As to prevent children's growth and development disorders. The method used in this research is pre-experimental with a quantitative approach. The research was carried out at Hanjuang Samijaya Elementary School in July 2022 with a sample of 15 students. The stages of the research are pretest, socialization of the importance of vitamins and minerals for the growth of children aged 12 years, and posttest. Based on the results of the study, students' understanding of the importance of vitamin and mineral intake for the growth of 12-year-old children increased after being given socialization. The percentage of students' average N-Gain score is 60%. This indicates the socialization carried out is quite effective. This is because of the enthusiasm of students in paying attention when socialization is being held, then the information can be conveyed and understood properly. Students who previously did not know and paid less attention to the vitamins and minerals their bodies needed, became more aware of and paid attention to the importance of these things. With this research, it is hopedevery parent and child will pay attention to the intake of vitamins and minerals needed by the body. As to avoid impaired child growth and development.

To the best of our knowledge, prior research has yet to delve into the combined and interactive relationships between maternal exposure to essential elements and toxic metals and infancy’s continuous growth and trajectories. This study aims to discern infant growth trajectories in the first year of life and to determine the associations of maternal serum levels of essential elements and toxic metals with growth trajectory. Within a Chinese prospective cohort in 2019 − 2021, 407 mother−infant pairs were included, and the serum levels of five essential elements (zinc, calcium, copper, magnesium and iron) and two toxic metals (cadmium and lead) in early pregnancy were assessed. The growth trajectory of infants was followed until age one year. Raw BMI and height values were transformed to age- and sex-specific BMI and height standard deviation (SD) scores. Latent-class group-based trajectory models and piecewise linear mixed regression were estimated to determine infant growth trajectories and growth velocity, respectively. The individual relationship between maternal metallic element levels and infant growth trajectory was examined using multinomial logistic regression models and linear mixed regression, while joint associations and interactive relationships were explored using Bayesian kernel machine regression (BKMR) following confounder adjustments. Four distinct trajectory patterns based on BMI-z score (low-rapid BMI gain group, normal-stable BMI group, very low-rapid BMI gain group and normal-rapid BMI gain group) and length-for-age (high-stable length group, low-stable length group, normal-rapid length gain group, very low-rapid length gain group) were identified during the first year post-birth, respectively. In single-metal and multiple-metal models, infants born to mothers with higher serum Zn and lower serum Cu levels were associated with a normal-rapid BMI gain trajectory during the first year. Serum Cu exhibited a positive correlation with the rate of BMI change solely in infants aged 6–12 months. Further, the BKMR analysis revealed a statistically significant and negative joint effect of the five essential elements on the likelihood of normal-rapid BMI/length gain trajectory when serum levels of these elements fell below the 70th percentile compared to median levels. In addition, high levels of serum copper and calcium interactively affect the rates of BMI change during 6–12 months old (β: −0.21, 95% CI: −0.44, −0.03, P = 0.04, P-interaction=0.04). In conclusion, maternal trace elements at early pregnancy are linked to infant growth patterns and growth velocity in the first year of life.

We assessed changes in the sociodemographic structure, land use, diet, and nutritional status of the population of a rural village in West Java, Indonesia between 2000–2001 and 2015–2017, a period of rapid socioeconomic change in the country. Over this period, the village's population increased by 50%, largely comprised of individuals engaged in non-agricultural employment in the village or in nearby cities, and the village maintained its farming characteristics without major changes in the local land use or ecosystem. In 2000, the diet, nutritional intake, and health status of the villagers were generally uniform. Indicators based on BMI, for example, classified 98% of target children and 70% of target mothers as 'normal', regardless of household economic status. However, by 2015, more people worked outside the village and dependence on a market economy had increased. Dependence on food from outside the village, such as processed foods that are cheap and easy to obtain and store, had also increased. Foods such as cassava, taro, and sweet potatoes, which were grown and consumed in 2000, were not consumed in 2015. The quantities of beans, nuts, and vegetables consumed had also decreased. Additionally, the use and sharing of natural resources and the accompanying knowledge transfer had been gradually lost. As a result, variation in diet, nutritional intake, and health conditions within the village significantly increased over time, and overnutrition and undernutrition coexisted by 2015.

The purpose of this study is to examine associations between maternal lipid profiles in pregnancy and offspring growth trajectories in a largely macrosomic cohort. This is a secondary analysis of the ROLO birth cohort (n = 293), which took place in the National Maternity Hospital, Dublin, Ireland. Infants were mostly macrosomic, with 55% having a birthweight > 4 kg. Maternal mean age was 32.4 years (SD 3.9 years), mean BMI was 26.1 kg/m2 (SD 4.4 kg/m2) and 48% of children born were males. Total cholesterol, high density lipoprotein cholesterol (HDL-cholesterol), low density lipoprotein cholesterol (LDL-cholesterol) and triglycerides were measured from fasting blood samples of mothers at 14 and 28 week gestation. The change in maternal lipid levels from early to late pregnancy was also examined. Offspring abdominal circumference and weight were measured at 20- and 34-week gestation, birth, 6 months, 2 years and 5 years postnatal. Linear spline multilevel models examined associations between maternal blood lipid profiles and offspring growth. We found some weak, significant associations between maternal blood lipids and trajectories of offspring growth. Significant findings were close to the null, providing limited evidence. For instance, 1 mmol/L increase in maternal triglycerides was associated with faster infant weight growth from 20- to 34-week gestation (0.01 kg/week, 95% CI − 0.02, − 0.001) and slower abdominal circumference from 2 to 5 years (0.01 cm/week, 95% CI − 0.02, − 0.001). These findings do not provide evidence of a clinically meaningful effect. Conclusion: These findings raise questions about the efficacy of interventions targeting maternal blood lipid profiles in pregnancies at risk of macrosomia. New studies on this topic are needed. What is Known: • Maternal fat accumulation during early pregnancy may potentially support fetal growth in the third trimester by providing a reserve of lipids that are broken down and transferred to the infant across the placental barrier. • There are limited studies exploring the impact of maternal lipid profiles on infant and child health using growth trajectories spanning prenatal to postnatal life. What is New: • Maternal blood lipid profiles were not associated with offspring growth trajectories of weight and abdominal circumference during pregnancy up to 5 years of age in a largely macrosomic cohort, as significant findings were close to the null, providing limited evidence for a clinically meaningful relationship. • Strengths of this work include the use of infant growth trajectories that span prenatal to postnatal life and inclusion of analyses of the change of maternal lipid levels from early to late pregnancy and their associations with offspring growth trajectories from 20-week gestation to 5 years of age.

Persistent organic pollutants (POPs) are compounds that are recalcitrant and ubiquitous that bioaccumulate in human milk (HM) and can impact infant growth and development. We explore the association between POP concentration in HM at 2–50 days postpartum and infant growth and development trajectory throughout the first year of life. A cohort of 68 healthy adult Brazilian women and their infants were followed from 28 to 35 gestational weeks to 12 months postpartum. HM samples were collected between 2 and 50 days postpartum, and POP concentrations were analyzed using gas chromatography with mass spectrometry. Concentrations of POPs >limit of quantification (LOQ) were defined as presence, and concentrations ≤LOQ as an absence. Growth z-scores were analyzed according to WHO growth charts and infant development scores according to Age & Stages Questionnaires at 1 (n = 66), 6 (n = 50), and 12 months (n = 45). Linear mixed effects (LME) models were used to investigate the association of POPs in HM with infant growth and development. Benjamini-Hochberg (BH) correction for multiple testing was performed to reduce the false discovery ratio. P < 0.1 was considered for models with the interaction between POPs and time/sex. After BH correction, adjusted LME models with time interaction showed (1) a positive association between the presence of β hexachlorocyclohexane and an increase in head circumference-for-age z-score (β = 0.003, P = 0.095); (2) negative associations between total POPs (β = −0.000002, P = 0.10), total organochlorine pesticides (β = −0.000002, P = 0.10), and dichlorodiphenyldichloroethylene concentrations in HM (β = −0.000002, P = 0.10) and fine motor scores. No statistical difference between the sexes was observed. Postnatal exposure to organochlorine pesticides in HM shows a positive association with the trajectory of head circumference-for-age z-score and a negative association with the trajectories of fine motor skills scores. Future studies on POP variation in HM at different postpartum times and their effect on infant growth and development should be encouraged. [ABSTRACT FROM AUTHOR]

Stunting currently affects 37% (1.1 million) of Malawian children and causing unfavorable impact for both children and their households. Identifying risk factors to stunting would go a long way in developing appropriate interventions. The objective of this study was to identify the risk factors of stunting among children aged below 60 months from Balaka, Dedza and Mzimba districts in Malawi. A matched cross-sectional case-control study was conducted among 913 (446 controls; 467 cases) children aged below 60 months from three regions of Malawi. Household demographic, anthropometric measurements, dietary intake, food security, and morbidity information were collected. Case-Control Stepwise multiple logistic regression models are used to determine risk factors of stunting. The following were identified as risk factors for stunting including; age of child (AOR= 6.3; 95% CI: 2.9, 8.9), polygamy (AOR= 8.9; 95%, CI: 3.3, 13.03), maternal education (AOR= 9.9; 95%, CI: 2.8, 20.1), access to markets (AOR= 1.3; 95%, CI: 0.2, 2.4), childhood infections (AOR= 2.11; 95%, CI: 1.4, 4.2) and presence of oedema (AOR= 2.5; 95%, CI: 1.3, 4.1). Also, lack of food any month (AOR= 1.31; 95%, CI: 1.01, 4.9), purchasing food on credit (AOR= 1.48; 95%, CI: 1.4, 1.7), begging for food (AOR= 1.55; 95%, CI: 1.2, 2.1), mothers or caregivers consuming less than 5 food groups (MDD-W) (AOR = 4.83; 95% CI: 1.9, 16.4), exclusive breastfeeding (AOR= 5.45; 95%, CI: 4.33, 7.61) children weaned on plain water (AOR= 1.6; 95%, CI: 1.6, 2.41), powdered milk (AOR= 0.63; 95%, CI: 0.4, 1.32), juices (AOR= 0.44; 95%, CI: 0.12, 0.96) and children fed on sugary food (AOR= 0.66; 95%, CI: 0.4, 0.99) were significantly related to stunting. Stunting is associated with increasing age of children, boys, polygamous households, lack of education by mothers or caregivers, inaccessible markets, childhood infections and presence of oedema, food insecurity, breastfeeding and complementary feeding among children and dietary diversity of mothers or caregivers. These results suggest that interventions against childhood stunting should be designed according to the factors that significantly affect stunting. [ABSTRACT FROM AUTHOR]

Choline and DHA are nutrients that, when provided during the first 1000 days from conception to age 2 years, may have beneficial effects on child neurodevelopment as well as related health factors, including birth outcomes and child growth, morbidity, and inflammation.

Here, a narrative review is presented of studies describing the pre- and postnatal roles of choline, docosahexaenoic acid, and a combination of the 2 nutrients on child neurodevelopment, birth outcomes, growth, morbidity, and inflammation in low- and middle-income countries. More studies are needed to understand the specific, long-term effects of perinatal choline and docosahexaenoic acid intake in various contexts.

Abstract Background Protracted, internal conflicts with geographic variations within countries, are an important understudied community exposure for adverse child health outcomes. Methods Violent events from the Uppsala Conflict Data Program (UCDP) between January 2016–December 2020 and January 2010–December 2015, were included as exposure events for children sampled in National Family Health Surveys (NFHS) 5 (2019–21) and NFHS 4 (2015–16), respectively. Geocoded data from UCDP were merged with residential clusters from NFHS, to identify children living in villages or urban blocks situated at

Transforming growth factor beta-1 (TGFβ1) is an adipokine secreted from adipose tissue, placental tissue and immune cells with a role in cell proliferation, cell apoptosis and angiogenic proliferation. The role of TGFβ1 in pregnancy and child growth and the source of cord TGFβ1 are yet unknown. In this study, we sought to clarify the correlation of TGFβ1 levels with parameters of intrauterine growth and child growth during the first year of life, and to determine whether their source is primarily of fetal or maternal origin. Serum samples and anthropometric measurements were obtained from the LIFE Child cohort of 79 healthy mother–child pairs. Measurements were conducted using enzyme-linked immunosorbent assays. Statistical analyses including Mann–Whitney U-test, correlation analyses and linear regression analyses were performed using GraphPad Prism and R. TGFβ1 levels were significantly higher in cord than in maternal serum, suggesting a fetal origin. Multivariate regression analyses revealed strong positive associations between cord TGFβ1 levels at birth and child weight at U6. Furthermore, cord TGFβ1 was significantly correlated with child weight at approximately one year of age. An increase of 10,000 pg/mL in cord TGFβ1 concentrations at birth was associated with a higher body weight of 201 g at roughly one year of age when adjusted for sex. [ABSTRACT FROM AUTHOR]

Our objective was to quantify the effects of yogurt supplementation and nutrition education over three months on the linear growth of infants at risk of stunting. We conducted a three-arm pilot randomized controlled trial: (1) nutrition education for mothers; (2) nutrition education plus a daily yogurt supplement (50 g) for the index child; and (3) usual care (control). Dyads of children aged 4–6 months and at risk of stunting [length-for-age z-score (LAZ) ≤ −1 SD and >−2 SD] and their mothers with ≤10 years of education were eligible for the study. Participants were recruited from five slum areas in Dhaka, Bangladesh. Intention-to-treat (N = 162) and complete-case analyses (N = 127) showed no between-group statistically significant differences in LAZ or weight-for-age (WAZ). However, the yogurt group showed greater change in linear growth compared to the control (LAZ: mean difference 0.20, 95% CI: −0.06, 0.47, p-value 0.13), which was also slightly greater than the education-only group. Children in the yogurt plus group were five times (95% CI: 0.80, 31.80, p-value 0.09) more likely to meet the minimum dietary diversity (MDD) score compared to the control. A 3-month follow-up of this pilot study did not demonstrate that yogurt was beneficial to linear growth. However, there were encouraging trends that merit replication of the intervention with larger samples and longer follow-ups. [ABSTRACT FROM AUTHOR]

Few studies have evaluated the impact of nutritional supplementation among pregnant adolescents. We examined the effects of the Rang Din Nutrition Study (RDNS) interventions on children born to mothers

Pregnancy and breastfeeding make demands on maternal nutrient stores. The extent of depletion and the degree to which nutrient stores are replenished between pregnancies has implications for a mother's nutritional status at conception of the subsequent child and therefore that child's birth outcomes and growth. Using follow-up data collected several years after a randomized effectiveness trial conducted in rural Bangladesh and a randomized efficacy trial conducted in semiurban Ghana, we evaluated the impact of maternal supplementation with small-quantity lipid-based nutrient supplements (LNS) or multiple micronutrients (MMN) through pregnancy (the index pregnancy) and 6 months postpartum on the growth status of the next living younger sibling conceived and born after the index pregnancy. In both Bangladesh (n = 472 younger siblings) and Ghana (n = 327 younger siblings), there were no overall differences in the growth status or the prevalence of undernutrition among younger siblings whose mothers had received LNS (or MMN, Ghana only) during and after the index pregnancy compared with the younger siblings of mothers who had received iron plus folic acid (IFA) during the index pregnancy (Ghana) or during and for 3 months after the index pregnancy (Bangladesh). These findings do not indicate that preconception nutrition interventions do not improve child growth. Rather, they suggest that any benefits of maternal LNS or MMN supplementation during one pregnancy and for 6 months postpartum are unlikely to extend to the growth of her next child beyond any effects due to IFA alone.

Background During armed conflict, the non-combative population, and particularly children, are susceptible to the effects of conflict from a variety of perspectives; psychological stress, loss of food and resources, loss of accommodation, occupation, income, death of family members, etc. The Lancet recently published a special issue entitled ‘Maternal and child health and armed conflict’ concluding that the ways in which health can be affected by conflict are protean but systematic evidence is sparse, whatever evidence exists is localised and of low to moderate quality, and that data on adolescents are sparse to non-existent. Whilst this may be true of the challenging environments of conflicts in developing countries, historically recent conflicts in Europe provide an alternative viewpoint that is frequently aired in the Auxological literature but is virtually unknown and/or unrecognised in health settings. Methods The current paper summarises three previously published studies based on repeated cross-sectional child growth surveys in London, Oslo, and Stuttgart covering the years of the Second World War. Taken together these studies provide extensive evidence of the response of children to armed conflict in the context of secular tends in growth of children living in industrialised nations during the twentieth century. Conclusions The conclusions to all three studies may be summarised, with regard to children in industrialised nations, as: (1) armed conflict adversely affects human growth and health, (2) armed conflict affects all age groups but adolescents more so, (3) all age groups recover from poor growth as conditions improve in relation to post-war health and welfare programmes, (4) pre-war differences in size between SES groups diminish during post-war recovery when accompanied by nutritional, welfare and reconstruction programmes.

To investigate the association between enteric pathogens, fecal microbes, and child growth, we conducted a prospective cohort study of 236 children 3 pathogens in their feces. We observed larger increases in height-for-age-z-scores from baseline to the 6-month follow-up among children with Akkermansia muciniphila in their feces (coefficient 0.02 [95% CI 0.0001–0.04]; p = 0.04). Children with Cryptosporidium in their feces had larger declines in weight-for-height/length z-scores from baseline to the 6-month follow-up (coefficient –0.03 [95% CI –0.05 to –0.005]; p = 0.02). Our study showed high prevalence of enteric pathogens among this pediatric cohort and suggests A. muciniphila can potentially serve as a probiotic to improve child growth.

Pastoralists in East Africa are among the world’s most vulnerable communities to climate change, already living near their upper thermal limits and engaging in a climate-sensitive livelihood in a climate change global hot spot. Pregnant women and children are even more at risk. Here, we report the findings of a study characterizing Samburu pastoralist women’s experiences of severe drought and outcomes in their children (N = 213, 1.8–9.6 y). First, we examined potential DNA methylation (DNAm) differences between children exposed to severe drought in utero and same-sex unexposed siblings. Next, we performed a high-dimensional mediation analysis to test whether DNAm mediated associations of exposure to severe drought with body weight and adiposity. DNAm was measured using the Infinium MethylationEPIC BeadChip array. After quality control; batch, chip, and genomic inflation corrections; covariate adjustment; and multiple testing correction, 16 CpG sites were differentially methylated between exposed and unexposed children, predominantly in metabolism and immune function pathways. We found a significant indirect effect of drought exposure on child body weight through cg03771070. Our results are the first to identify biological mediators linking severe drought to child growth in a low-income global hot spot for climate change. A better understanding of the mechanisms underlying the association between drought exposure and child growth is important to increasing climate change resilience by identifying targets for intervention.
