Study ObjectiveTo describe height, weight, and body mass index (BMI) of the adult urban population in Mumbai, western India and to estimate the prevalence and severity of thinness and overweight in this population. To describe the association of BMI with education, age, and tobacco habits in an urban Indian population.DesignCross sectional representative survey of 99 598 adults (40 071 men and 59 527 women).SettingThe survey was carried out in the city of Mumbai (formerly known as Bombay) in western India.ParticipantsMen and women aged > or =35 years who were residents of the main city of Mumbai.Main ResultsThe mean height, weight, and BMI were 161.0 (SD 6.7) cm, 56.7 (SD 11.0) kg, and 21.8 (SD 3.8) kg/m(2) for men and 148.0 (SD 6.2) cm, 49.8 (SD 11.2) kg, and 22.7 (SD 4.7) kg/m(2) for women, respectively. Some 19% of men and women were thin (BMI<18.5 kg/m(2)), while 19% of men and 30% of women were overweight (BMI> or =25kg/m(2)). Multivariable logistic regression analyses showed that age, level of education, and tobacco use were independently associated with BMI. The odds ratio (OR) and 95% confidence intervals (CI) for thinness (BMI<18.5 kg/m(2)) were OR 6.52, 95%CI 5.38 to 7.89 for men and OR 4.83, 95%CI 3.71 to 6.28 for women, respectively, (p<0.001) for the lowest level of education (illiterate group). The OR and 95%CI for overweight were 2.25, 2.20 to 2.58 for college educated men and 1.90, 1.64 to 2.20 for college educated women, respectively, p<0.001. Both smoking (2.33, 2.09 to 2.59; 2.89, 1.77 to 4.72 for men and women, respectively, p<0.001) and smokeless tobacco use (1.65, 1.52 to 1.80; 2.26, 2.14 to 2.38 for men and women, respectively p<0.0001) were significantly associated with low BMI.ConclusionsSequelae of thinness and overweight represent major public health problems. The results of this study, indicating an equal prevalence of thinness and overweight in an urban area and their association with age, level of education, and tobacco use raise concerns of an emerging public health crisis in urban India.
