Early anthropometric indices predict short stature and overweight status in a cohort of Peruvians in early adolescence
Sterling R , Miranda JJ , Gilman RH , Cabrera L , Sterling CR , Bern C , Checkley W . Am J Phys Anthropol 2012 148 (3) 451-61 While childhood malnutrition is associated with increased morbidity and mortality, less well understood is how early childhood growth influences height and body composition later in life. We revisited 152 Peruvian children who participated in a birth cohort study between 1995 and 1998, and obtained anthropometric and bioimpedance measurements 11-14 years later. We used multivariable regression models to study the effects of childhood anthropometric indices on height and body composition in early adolescence. Each standard deviation decrease in length-for-age at birth was associated with a decrease in adolescent height-for-age of 0.7 SD in both boys and girls (all P < 0.001) and 9.7 greater odds of stunting (95% CI 3.3-28.6). Each SD decrease in length-for-age in the first 30 months of life was associated with a decrease in adolescent height-for-age of 0.4 in boys and 0.6 standard deviation in girls (all P < 0.001) and with 5.8 greater odds of stunting (95% CI 2.6-13.5). The effect of weight gain during early childhood on weight in early adolescence was more complex to understand. Weight-for-length at birth and rate of change in weight-for-length in early childhood were positively associated with age- and sex-adjusted body mass index and a greater risk of being overweight in early adolescence. Linear growth retardation in early childhood is a strong determinant of adolescent stature, indicating that, in developing countries, growth failure in height during early childhood persists through early adolescence. Interventions addressing linear growth retardation in childhood are likely to improve adolescent stature and related-health outcomes in adulthood. (Am J Phys Anthropol 148:451-461, 2012.

Effects of the 1997-1998 El Nino episode on community rates of diarrhea

Am J Public Health 2012 102 (7) e63-9 OBJECTIVES: To improve our understanding of climate variability and diarrheal disease at the community level and inform predictions for future climate change scenarios, we examined whether the El Nino climate pattern is associated with increased rates of diarrhea among Peruvian children. METHODS: We analyzed daily surveillance data for 367 children aged 0 to 12 years from 2 cohorts in a peri-urban shantytown in Lima, Peru, 1995 through 1998. We stratified diarrheal incidence by 6-month age categories, season, and El Nino, and modeled between-subject heterogeneity with random effects Poisson models. RESULTS: Spring diarrheal incidence increased by 55% during El Nino compared with before El Nino. This increase was most acute among children older than 60 months, for whom the risk of a diarrheal episode during the El Nino spring was nearly 100% greater (relative risk = 1.96; 95% confidence interval = 1.24, 3.09). CONCLUSIONS: El Nino-associated climate variability affects community rates of diarrhea, particularly during the cooler seasons and among older children. Public health officials should develop preventive strategies for future El Nino episodes to mitigate the increased risk of diarrheal disease in vulnerable communities. (Am J Public Health.
