To determine whether screen time and physical activity is related to overweight or obesity in adolescents.
Cross-sectional design. Adolescents aged 10 to 19 were included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006). The dependent variable was overweight or obesity; the independent variable was screen time. A logistic regression model was created to estimate the relationship of overweight and obesity to various factors, including screen time, physical activity, study vs. no study, age, sex, indigenous ethnicity, alcohol consumption and tobacco use.
A total of 18 784 adolescents were included. A positive relation between screen time and overweight and obesity was found.
Screen time is associated with overweight and obesity in Mexican adolescents.

横断面设计。纳入了年龄在 10 至 19 岁的墨西哥全国健康和营养调查 2006 年（ENSANUT 2006）的青少年。因变量为超重或肥胖；自变量为屏幕时间。创建了一个逻辑回归模型来估计超重和肥胖与各种因素（包括屏幕时间、身体活动、学习与不学习、年龄、性别、土著民族、饮酒和吸烟）之间的关系。
共纳入了 18784 名青少年。发现屏幕时间与超重和肥胖呈正相关。
