目的：探讨中国成年人看电视时间与体质指数（BMI）和肥胖的关系。方法纳入2010年中国慢性非传染性疾病及其危险因素监测的所有调查对象。应用问卷收集调查对象的基本信息、患病状况、身体活动情况及业余静态行为等信息。测量调查对象的体重和身高，并计算BMI。运用多元线性回归和多因素Logistic回归模型检验每日看电视时间与BMI和肥胖的关系。结果我国成年人每天用于看电视的平均时间为（1.87±0.03）小时，男性看电视时间长于女性，45～54岁中等教育水平的人每天看电视时间最长。多元线性回归结果提示，每天看电视时间与BMI存在线性关系（β＝0.17， P＜0.001），女性（β＝0.21，P＜0.001）和≥65岁（β＝0.26，P＜0.001）人群的相关性最强。Logistic多因素回归分析提示每日看电视时间每增加1小时，人群患肥胖的相对危险度（RR）增加4%（95%CI：1.01～1.07），女性（OR：1.08，95%CI：1.04～1.11）和≥65岁人群（OR：1.12，95%CI：1.07～1.18）患病风险最大。结论不同人群看电视时间不同，看电视时间越长，BMI增加和罹患肥胖的危险性越大，且对女性和老年人群的影响最大。

Objective The goal of this study was to assess the associations of television viewing time and body mass index (BMI) and risk of obesity. Method The subjects from 2010 Chronic Non-communicable Disease&Risk Factor Surveillance in China were included in this study. Questionnaire was used to collect information on general information, health status, physical activity and leisure time activity. Weight and height of each subject were measured, and then BMI were calculated. The linear regression models and multiple logistic regression analysis were used to assess the association of television viewing time with BMI and obesity. Result The average television viewing time of Chinese adults was (1.87±0.03) hours. Television viewing time of men was longer than women. The viewing time of 45~54 years group and middle education group people was the longest. The television viewing time was signiifcantly associated with BMI (β=0.17, P<0.001), and the association was stronger in women (β=0.21, P<0.001) and≥65 years group (β=0.26, P<0.001). An hour increase in daily television viewing was associated with 4%(95%CI:1.01~1.07), and the risk of women (OR:1.08, 95%CI:1.04~1.11) and≥65 years group people (OR:1.12, 95%CI:1.07~1.18) was the largest. Conclusion Television viewing time positively associated with BMI and obesity. The association is the strongest in women and≥65 years people.
