Body weight perception is associated with socio-economic status and current body weight in selected urban and rural South Indian school-going children.

OBJECTIVE To evaluate the current and ideal body weight perceptions of schoolchildren in relation to their actual body weight and socio-economic status (SES). DESIGN Baseline evaluation of schoolchildren from January 2008 to April 2008 as part of a 3-year longitudinal study. SETTING City and non-city locations, Karnataka State, South India. SUBJECTS Schoolchildren (n 1877) aged between 8 and 14 years. RESULTS Girls, children of more educated parents and city dwellers were more likely to be overweight (P < 0.001). Younger children aged <10 years and those of lower SES were more likely to perceive themselves as underweight (adjusted OR = 1.63, 95 % CI 1.25, 2.11 and adjusted OR = 1.87, 95 % CI 1.32, 2.65). Underweight children were ten times more likely to overestimate their current weight status, while overweight children were four times more likely to underestimate it. The odds of children of lower SES underestimating their weight, as well as desiring a higher weight, were higher than those of higher-SES children. CONCLUSIONS SES is associated with body weight perception. Underweight children are more likely to overestimate their weight status and overweight children more likely to underestimate it.
