在儿童和青少年中，看电视与超重、体力活动减少和不健康的饮食行为有关，可能是儿童肥胖的一个可改变的原因。这项研究调查了美国高中生在这些联系中的种族、民族和性别差异。这项研究分析了1999年全国青少年危险行为调查的数据，这是一个具有代表性的美国高中生样本(N=15,349)。Logistic回归检验了显著的相关性。43%的学生平均每天在学校看电视超过2小时；黑人(74%)和西班牙裔(52%)的学生比白人(34%)的学生看电视的时间更多。总体而言，11%的学生超重，31%的学生久坐不动(即没有参加推荐水平的中等或剧烈体育活动)，76%的学生每天吃的水果和蔬菜少于5份。在白人女性中，每天看电视超过2小时与超重、久坐不动、水果和蔬菜摄入不足有关，在西班牙裔女性中与超重有关。在黑人女性中没有发现明显的关联。在白人男性中，看电视与超重和水果和蔬菜摄入不足有关。在西班牙裔男性中没有发现明显的关联。在黑人男性中，看电视与更多地参与体育活动有关。这些发现表明，在制定通过减少青少年看电视来促进体育活动、健康饮食和健康体重的干预措施时，需要考虑文化因素的存在。
Television (TV) viewing has been associated with overweight, decreased physical activity, and unhealthy dietary behavior among children and adolescents, and may represent a modifiable cause of childhood obesity. This study examined race, ethnic, and gender-specific differences in these associations among high school students in the United States. The study analyzed data from the 1999 national Youth Risk Behavior Survey, a representative sample (N = 15,349) of US high school students. Logistic regression tested for significant associations. TV viewing on an average school day exceeded 2 hours/day among 43% of students; it was greater among Black (74%) and Hispanic (52%) than White (34%) students. Overall, 11% of students were overweight, 31% of students were sedentary (ie, did not participate in moderate or vigorous physical activity at recommended levels), and 76% ate less than five servings/day of fruits and vegetables. Watching TV more than 2 hours/day was associated with being overweight, being sedentary, and eating insufficient fruits and vegetables among White females, and with being overweight among Hispanic females. No significant associations were found among Black females. TV viewing was associated with being overweight and eating insufficient fruits and vegetables among White males. No significant associations were found among Hispanic males. Among Black males, TV viewing was associated with greater participation in physical activity. These findings suggest the presence of cultural factors to consider when developing interventions to promote physical activity, healthy eating, and healthy weight through reduced TV viewing among adolescents.
