title: Foraging to settled life: a comparative study of anthropometry and nutrition of Onges of Little Andaman Island.
abstract: The aim of this study is to examine the impact of forced settlement among the foraging Onges, which induced them to change their subsistence from full time foragers to settled consumer. Anthropometric study along with dietary investigation was considered before and afterwards they were forcibly settled. The anthropometric variables and indices show gradual increase among the Onges males but not so much in females. High prevalence of overweight and obesity is also reported. Comparison with other Andaman Islanders indicates that the group which was under the developmental schemes (forced to settle), is showing more mean values of anthropometric variables with prevalence of overweight and obesity than the group, which was not under the influence of developmental programme. Their dietary pattern and physical activity changed to a great extent. The protein content of the diets reduced significantly and the fat along with carbohydrates increased to a substantial amount. The contribution of protein to calories has been reduced substantially and now it is only around 10%, whereas in the past it was above 30%. Caloric intakes increased more than two times, while the physical activity level reduced to about half time. Decreased mobility and altered food habits are the probable reason for the gradual increase of body dimensions and prevalent overweight and obesity, which are the outcomes of forced settlement.
