Body size and weight status of adult Indian males born in the 1890s–1950s: Age and secular change in the context of demographic, economic, and political transformation

Abstract

AbstractObjectivesTo evaluate secular change in body size and weight status of adult Indian males born in 1891–1957 and surveyed in the 1970s.MethodsData are from Anthropological Surveys. Only men were included in the surveys due to high female illiteracy and lack of female researchers. Indian society was also strongly conservative at the time, especially in rural areas, and the measurement of women by men was not permitted. Heights and weights of 43 950 males 18–84 years (born 1891–1957) were measured. The BMI was calculated; weight status of individuals was classified relative to WHO criteria and suggested criteria for the Asia‐Pacific region. Heights of men 35+ years were also adjusted for age‐related stature loss. Trends in measured and adjusted heights, body weight and the BMI, and in weight status were evaluated by age groups. Linear regression of measured height and adjusted height on year of birth was used to estimate secular effects.ResultsMean heights declined slightly with age to 50 years and declined sharply through 60+ years, while mean weights increased into the 40s and then declined. Mean BMIs were relatively stable from 30 to 60 years. The prevalence of thinness and normal weight was high, while that of overweight and obesity was low. Regression analyses indicated limited secular change across the total range of birth years but suggested a decline in adjusted heights among men born in 1891 through the 1930s, and little change among men born subsequently.ConclusionsAge‐related trends and results of the regression analyses by year of birth indicated negligible secular change in heights of Indian men 18–84 years born between 1891 and 1957. BMIs indicated a high prevalence of thinness and normal weight and low prevalence of overweight and obesity.
