To identify important factors (linked to lifestyle, eating and sedentary behaviors) relating to waist circumference among urban South Indian children aged 3 to 16 years.
Cross sectional.
Urban schools of Bangalore, from August 2008 to January 2010.
8444 children; 4707 children aged 3-10 years and 3737 children aged 10-16 years.
Data were collected on the frequency of consumption of certain foods, physical activity patterns, sedentary habits at home, sleep duration and behaviors such as habits of snacking, skipping breakfast, eating in front of television and frequency of eating out. Simple linear regression analysis of waist circumference on various food items, physical activity, behavior and parental BMI were performed. A path model was developed to identify potential causal pathways to increase in waist circumference.
Increased consumption of bakery items, non vegetarian foods, increased television viewing, decreased sleep duration, eating while watching television, snacking between meals, family meals, skipping breakfast (in older children), and parental BMI were found to be related to waist circumference. Older children possibly under-reported their intake of unhealthy foods, but not behaviors.
This study identified potential behaviors related to waist circumference in urban school children in India. Longitudinal studies with better measures of morbidity and adiposity are warranted in order to derive casual relationships between various determinants and waist circumference.
确定与南印度城市儿童（3 至 16 岁）腰围相关的重要因素（与生活方式、饮食和久坐行为相关）。
横断面研究。
班加罗尔市的城市学校，2008 年 8 月至 2010 年 1 月。
8444 名儿童；3-10 岁儿童 4707 名，10-16 岁儿童 3737 名。
收集了某些食物的消费频率、体力活动模式、在家中的久坐习惯、睡眠时间以及吃零食、不吃早餐、边看电视边吃饭和外出就餐频率等行为的数据。对腰围与各种食物、体力活动、行为和父母 BMI 进行简单线性回归分析。建立路径模型以确定导致腰围增加的潜在因果途径。
发现增加面包店食品、非素食食品的消费、增加看电视时间、减少睡眠时间、边吃饭边看电视、吃零食、家庭用餐、不吃早餐（年龄较大的儿童）和父母 BMI 与腰围有关。年龄较大的儿童可能会少报他们摄入的不健康食品，但不会少报行为。
本研究确定了印度城市学龄儿童腰围相关的潜在行为。需要进行具有更好发病率和肥胖症测量的纵向研究，以得出各种决定因素与腰围之间的因果关系。
