title: The impact of caste on the growth of male Sikhs in Punjab, India.
abstract: This study is based on a cross-sectional sample of 442 Sikh boys and young male adults who were born in and around the town of Phagwara, in the state of Punjab, India, and stayed there all their lives. The sample comprised Sikh boys at three crucial phases of growth, at 5-6, 10-11 and 15-16 years, and young adults around 18 years of age. The sample comprised three distinct caste groups, viz. Jats, Ramgarhias and Ravidassias, belonging respectively to upper, middle and lower socioeconomic strata of the Sikh community. Differences in stature and body weight are particularly marked around early adolescence, and there is some indication of caste differences reappearing in young adults. In the case of body mass index, however, the differences seem most marked in late adolescence. There is no clear directional pattern to the way skinfolds change, but inter-caste differences become more marked with age. There is a suggestion of continuing growth beyond 16 years of age, and indications that the well-off groups grow more, as compared to the poor groups, during this period. Comparisons of young adults with older groups of the same caste indicate an increase in body weight with age, but smaller stature in the older groups. There is thus evidence for a secular stature increase among present-day Punjabi Sikhs.
