Background : The association between extremes of relative body weight and mortality has not been well characterized in developing countries. A prospective cohort study was conducted in Mumbai (India) to study the association of relative body weight, as estimated by body mass index [BMI=weight (kg)/height2 (m2) ], with mortality. Methods : Using the voters'list as the selection frame, 148173 men and women aged>=35 years were recruited during 1991-97 in Mumbai city and were followed-up during 1997-2003. Results : During 774129 person-years of follow-up, 13261 deaths were observed. After adjusting for the potential confounders, increased mortality was observed in all under-weight categories [relative risk (RR)=1.94 for BMI=30.0) men
