ABSTRACT
Regional variation in the body size of Indian men 18-84 years of age (birth years 1891-1957) was considered. Heights, weights, and BMIs of Indian males from four regions of the country – North, East-Northeast, Central, and West were compared. Heights of men 35+ years of age were adjusted for estimated height loss with age; the estimate was added to observed height to provide an estimate of maximum height. Linear regressions of measured height and estimated maximum height on year of birth were used to evaluate secular change by region. Differences in measured and estimated maximum heights and weight among regions were significant in all age groups, while differences in the BMI were significant in all age groups except 55+ years. Men from the North region were tallest and those from the East-Northeast region were shortest, while body weight and the BMI varied among regions. Regression analyses of year of birth on measured and estimated maximum heights indicated small differences in estimates of secular change among regions but suggested a decline in estimated maximum heights with age among men in the four regions born in 1891 through the 1930s, and small but variable estimates of secular change in heights among men born in the 1930s through 1957. The variation likely reflected socio-economic disparities and ecological differences among regions, and by inference nutritional status though data are limited.
