We examined the effects of sedentary lifestyle and dietary habits on body mass index (BMI) change in a follow-up study of 325 women (aged 15-49 years) in Delhi, systematically selected from the 1998-1999 National Family Health Survey samples who were re-interviewed after 4 years in 2003. Information was collected on height, weight, dietary habits, and sedentary lifestyle through face-to-face interviews. Overall, a 2.0-point increase in mean BMI was found among women in just 4 years. Every second normal-BMI woman, two in five overweight women, and every fourth obese woman experienced a > 2.0-point increase in her mean BMI. High sedentary lifestyle (OR: 2.63; 95% CI: 1.29-5.35) emerged as the main predictor of a > 2.0-point increase in mean BMI in adjusted analysis, but there was weak evidence of association with the dietary covariates. Our findings suggest that a high sedentary lifestyle is a determinant of weight gain among adult women in urban India.
在一项针对德里325名年龄在15至49岁女性的随访研究中，我们研究了久坐不动的生活方式和饮食习惯对体重指数（BMI）变化的影响。这些女性是从1998 - 1999年全国家庭健康调查样本中系统选取的，并于2003年在4年后再次接受访谈。通过面对面访谈收集了身高、体重、饮食习惯和久坐不动生活方式的信息。总体而言，仅在4年时间里，女性的平均BMI就增加了2.0个点。每两名BMI正常的女性中就有一名、五分之二超重女性以及四分之一肥胖女性的平均BMI增加超过2.0个点。在调整分析中，久坐不动的生活方式（比值比：2.63；95%置信区间：1.29 - 5.35）成为平均BMI增加超过2.0个点的主要预测因素，但与饮食协变量的关联证据较弱。我们的研究结果表明，久坐不动的生活方式是印度城市成年女性体重增加的一个决定因素。
