“…Indeed, familial resemblance in total 30 fatness and regional fat distribution have been reported (Li and others 1996). Moderate familial similarities between mothers and children were found in the Oaxaca Valley of Mexico (Little and Malina 2005). In the present study, the prediction of children's phenotypes from maternal 2 BMI was moderate in boys and practically non-existent in girls.…”

Obesity is a worldwide public health problem impacting not only industrialized nations but also developing countries. The main objective of this paper was to analyze risk factors for overweight among Amerindian children and their mothers. Data were collected in 15 Amerindian riverside communities from the Beni River (Bolivia). The total sample was of 195 mothers and 452 children, 0–15 years of age. Information about family activity and dietary patterns was collected, and a clinical examination was performed. Stool samples were collected in children for parasitological screening. Anthropometric measurements, including weight, height, arm circumference, and four skinfolds, were taken. A bioelectrical impedance analysis was performed in mothers. In total, 12.2% (95% confidence interval (CI95%) 9.1–15.9%) of the children were considered overweight; less than 1% were overtly obese International Obesity Task Force (IOTF) criteria. Among their mothers, 35.3% (CI95%, 28.7–42.5%) were overweight (BMI (weight/height 2) >25 kg/m2), and 5% (CI95%, 2.5–5.1%) were obese (BMI >30 kg/m2). BMI was moderately related to anthropometric indices of body composition in children, but was highly correlated with fatness in mothers. The risk of overweight was not associated with environmental factors in children. In mothers, there was a significant relationship between BMI, health status, and dietary diversity score. There was a moderate association in boys between fatness and the BMI of their mothers (R2 = 0.12, P < 0.001), but not in girls. These findings suggest a trend toward accumulation of fat related to possible changes at the economic and agricultural levels, even in remote rural areas. Am. J. Hum.

“…60 Others have also found no relationship between obesity and adenomas when controlling for level of activity and dietary fiber intake. 61 Many of the studies looking strictly at BMI or other anthropomorphic measurements fail to factor in activity level and other dietary issues, again making it difficult to assign all of the increased risk directly to obesity.…”

Differential investment in offspring by parental and progeny gender has been discussed and periodically analyzed for the past 80 years as an evolutionary adaptive strategy. Parental investment theory suggests that parents in poor condition have offspring in poor condition. Conversely, parents in good condition give rise to offspring in good condition. As formalized in the Trivers-Willard hypothesis (TWH), investment in daughters will be greater under poor conditions while sons receive greater parental investment under good conditions. Condition is ultimately equated to offspring reproductive fitness, with parents apparently using a strategy to maximize their genetic contribution to future generations. Analyses of sex ratio have been used to support parental investment theory and in many instances, though not all, results provide support for TWH. In the present investigation, economic strategies were analyzed in the context of offspring sex ratio and survival to reproductive age in a Zapotec-speaking community in the Valley of Oaxaca, southern Mexico. Growth status of children, adult stature, and agricultural resources were analyzed as proxies for parental and progeny condition in present and prior generations. Traditional marriage practice in Mesoamerican peasant communities is patrilocal postnuptial residence with investments largely favoring sons. The alternative, practiced by ∼25% of parents, is matrilocal postnuptial residence which is an investment favoring daughters. Results indicated that sex ratio of offspring survival to reproductive age was related to economic strategy and differed significantly between the patrilocal and matrilocal strategies. Variance in sex ratio was affected by condition of parents and significant differences in survival to reproductive age were strongly associated with economic strategy. While the results strongly support TWH, further studies in traditional anthropological populations are needed.
