Abstract
INTRODUCTION We compare demographic, socioeconomic, and anthropometric characteristics and blood pressure (BP), between rural and urban Peruvian indigenous women. These are preliminary results from a project on urbanization, migration, and health. METHODS Data were collected cross-sectionally (2019) and compared between a rural (n = 92) and an urban (n = 93) community. RESULTS Height: μ = 148.3 ± 5.0 cm (range = 137-162), weight: μ = 62.0 ± 11.5 (range = 37.5-108.7), median waist circumference = 89.0 (IQR = 15.8, range = 64.0-126.0), BMI = 28.3 (IQR = 6.2, range = 16.7-40.0), with no significant rural-urban differences. Systolic but not diastolic BP was significantly higher in urban versus rural women (median = 110, IQR = 18, range = 80-170 vs. median = 120, IQR = 10, range = 90-170, p = .002 and median = 70, IQR = 17, range = 50-100 vs. median = 70, IQR = 10, range = 60-100, p = .354), respectively. CONCLUSIONS Despite major lifestyle differences, there were no anthropometric differences between rural and urban women. Higher systolic BP in urban women may reflect social/economic stressors rather than dietary factors.

Abstract
BACKGROUND Recent studies have shown associations between cesarean birth and overweight. However, very few studies have evaluated weight gain or adiposity throughout life, and the majority are restricted to analysis during childhood. The purpose of this study was to analyze the effect of cesarean birth on obesity risk from birth to adolescence. METHODS The study sample was drawn from live births that occurred in 1999 and 2000 in Mato Grosso-Brazil. Participants were evaluated once when they were between 0 and 5 years of age and again after approximately 10 years (2009-2011). To measure the association between cesarean birth and obesity (Body Mass Index/age >+2 z-scores), we used generalized estimation equations (GEE) with binomial distribution and log-binomial models for repeated measures, controlled by the following confounding factors: weight and length at birth, sex, gestational age, breastfeeding, maternal age and schooling, economic class in childhood, and maternal smoking during pregnancy. The exposure-time interaction term was evaluated to verify differences in the change in the risk of obesity over time. RESULTS 56.8% of children in the sample were born by cesarean birth. Children born by cesarean had a higher risk of obesity from birth through adolescence (RR = 1.22, 95% CI = 1.02; 1.46), even after adjusting for covariates, when compared with those born vaginally. However, the time-exposure interaction term was not significant, which indicates that there was no increased risk of obesity over time. CONCLUSION Cesarean birth was positively associated with obesity from birth to adolescence, with a persistent risk in the period evaluated.

Abstract
Early‐life conditions shape childhood growth and are affected by urbanization and the nutritional transition. To investigate how early‐life conditions (across the “first” and “second” 1000 days) are associated with rural and urban children's nutritional status, we analyzed anthropometric data from Maya children in Yucatan, Mexico. We collected weight, height and triceps skinfold measures, then computed body mass and fat mass indices (BMI/FMI), in a cross‐sectional sample of 6‐year‐olds (urban n = 72, rural n = 66). Demographic, socioeconomic and early‐life variables (birthweight/mode, rural/urban residence, household crowding) were collected by maternal interview. We statistically analyzed rural‐urban differences in demographic, socioeconomic, early‐life, and anthropometric variables, then created linear mixed models to evaluate associations between early‐life variables and child anthropometric outcomes. Two‐way interactions were tested between early‐life variables and child sex, and between early‐life variables and rural‐urban residence. Results showed that rural children were shorter‐statured, with lower overweight/obesity and cesarean delivery rates, compared to urban children. Household crowding was a negative predictor of anthropometric outcomes; the strongest effect was in boys and in urban children. Birthweight positively predicted anthropometric outcomes, especially weight/BMI. Birth mode was positively (not statistically) associated with any anthropometric outcome. Cesarean delivery was more common in boys than in girls, and predicted increased height in urban boys. In conclusion, urbanization and household crowding were the most powerful predictors of Maya 6‐year‐old anthropometry. The negative effects of crowding may disproportionately affect Maya boys versus girls and urban versus rural children. Early‐life conditions shape Maya children's nutritional status both in the “first” and “second” 1000 days.

Evol Med Public Health 2022; 10:36-46.

Abstract
BACKGROUND AND OBJECTIVES Cesarean section may lead to suboptimal breastfeeding outcomes, though evidence has been mixed. Factors, such as premature birth, birth weight and maternal age may independently increase risk of cesarean and hinder breastfeeding initiation, while maternal preferences, support and sociostructural barriers may influence breastfeeding practices beyond the immediate postpartum period. METHODOLOGY We assessed impacts of cesarean section and gestational factors on breastfeeding duration among Indigenous Qom mothers in Argentina who have strong traditional breastfeeding support. We modeled transitions from exclusive breastfeeding to complementary feeding and from complementary feeding to full weaning in a Bayesian time-to-event framework with birth mode and gestational covariates (n = 89 infants). RESULTS Estimated median time to full weaning was 30 months. Cesarean-delivered babies were weaned an average of 5 months later adjusting for gestational age, maternal parity and infant sex. No factors were associated with time-to-complementary feeding, and time-to-complementary feeding was not associated with time-to-full weaning. CONCLUSIONS AND IMPLICATIONS Among Indigenous Qom mothers in Argentina, cesarean section was not associated with suboptimal breastfeeding outcomes. Although some Qom mothers do experience early breastfeeding problems, particularly following first birth, problems are not more frequent following cesarean delivery. Traditional postpartum kin and community support during prolonged postpartum periods may be instrumental in helping mothers to overcome early breastfeeding problems due to cesarean or other risk factors.

Abstract
BACKGROUND Children's physical growth (PG) and body composition (BC) can be influenced by birth weight and type of delivery. AIM To longitudinally analyze the dynamics of PG and BC of children from 5 to 9 years; to investigate the inter-individual differences according to age, sex, BW, and type of delivery across the following years of the study. SUBJECTS AND METHODS A total of 1236 children (597 boys) were evaluated at 5-years of age and followed annually until 9-years. PG and BC measurements were evaluated. Multilevel modeling was used. RESULTS Annual increments were observed (p < .001). Girls presented lower height and fat-free-mass but higher %BF (p < .001). Distinct trajectories between the sexes were observed for height (p < .001). Low-birth-weight children presented lower height, body mass, and fat-free-mass (p < .001), but the interaction between velocity of growth and BC was significant only in height (p < .05). Children born by had lower height, body mass, and %BF, and gained less body mass per year than those born by vaginal delivery (p < .05). Significant inter-individual differences were observed at 5-years of age and in their trajectories, except for fat-free-mass (p < .01). CONCLUSION There are differences in the dynamics of PG and BC, low-birth-weight and type of delivery influence the dynamics of PG during this interval of ages.

Abstract
Obesity epidemic responsible for increase in diabetes, heart diseases, infections and cancer shows no signs of abating. Obesity in children is also on rise, indicating the urgent need of strategies for prevention and intervention that must begin in early life. While originally posited that obesity results from the simple concept of consuming more calories, or genetics, emerging research suggests that the bacteria living in our gut (gut microbiome) and its interactions with immune cells and metabolic organs including adipose tissues (microbiome-immune-metabolic axis) play significant role in obesity development in childhood. Specifically, abnormal changes (dysbiosis) in the gut microbiome, stimulation of inflammatory cytokines, and shifts in the metabolic functions of brown adipose tissue and the browning of white adipose tissue are associated with increased obesity. Many factors from as early as gestation appear to contribute in obesity, such as maternal health, diet, antibiotic use by mother and/or child, and birth and feeding methods. Herein, using evidence from animal and human studies, we discuss how these factors impact microbiome-immune-metabolic axis and cause obesity epidemic in children, and describe the gaps in knowledge that are warranted for future research.
