背景：在智利，超重和肥胖是公共卫生的紧迫问题。目的：确定影响青少年超重或肥胖可能性的个人、社会和环境因素。材料和方法：我们使用了2011年国家体育研究中获得的来自圣地亚哥的900名城市八年级学生的身体状况数据。这一信息得到了来自学生居住地及其生活环境的地理参考数据的补充。我们使用了三个逻辑回归模型来估计个体、社会和环境因素与超重或肥胖可能性之间的关系。结果：高社会经济地位（SES）的男性和学生超重的可能性较低（-6个百分点）。-12页分别）。此外，影响超重的决定因素取决于社会经济地位。也就是说，只有中等和低社会经济地位的男性超重的可能性较低（-7页）。参加学校体育活动降低了超重的可能性，只有中等和低社会经济地位的学生（-5，5页）。对于高社会经济地位的青少年，他们的学校和最近的快餐店之间的距离降低了超重的可能性（-4.7 pp.每公里）。结论：超重的决定因素因社会经济地位而异。公共政策设计应考虑到智利现实中的社会经济不平等。
Background: In Chile, overweight and obesity are pressing issues in public health. Aim: To identify individual, social and environmental factors that affect the likelihood of adolescents to become overweight or obese. Material and Methods: We used physical condition data of a sample of 900 urban eighth grade students from Santiago, obtained in the 2011 National Study of Physical Education. This information was complemented with georeferenced data from the place of residence of students and the environment in which they live. We used three logistic regression models to estimate the relationship between individual, social and environmental factors and the likelihood of being overweight or obese. Results: Men and students of high socioeconomic status (SES) have a lower probability of being overweight (-6 percentage points (pp.) and -12 pp. respectively). Furthermore, the determinants that affect overweight depend on SES. Namely, only men of middle and low SES have a lower probability of being overweight (-7 pp.). Participation in school sporting activities reduces the likelihood of being overweight only for students of middle and low SES (-5,5 pp.). For adolescents of high SES, the distance between their school and the nearest fast food restaurant decreases the likelihood of being overweight (-4.7 pp. per km.). Conclusions: The determinants of overweight differ by SES. Public policy design should consider socioeconomic inequalities that characterize the Chilean reality.
