目的：通过基线和1年运动和不运动数据的变化，研究美国青少年身体活动和不运动模式与超重之间的关系。研究方法和程序：来自全国12759名参与者（6997名非西班牙裔白人，2676名非西班牙裔黑人，2185名西班牙裔）的代表性数据。和901名亚洲人)在全国青少年健康纵向研究（1995年和1996年）中。从问卷调查中获得中度至剧烈和低强度体育活动、电视/视频观看和视频游戏/电脑使用的数据。多变量模型评估了超重（身体质量指数大于或等于疾病控制和预防中心/国家卫生统计中心2000曲线的第95百分位）与初始（和1年变化）活动和不活动水平的关系，控制了年龄。种族、社会经济地位、城市居住、吸烟和居住地区。结果：白人男孩（比值比[OR] = 1.52； 95%可信区间[1.08 ~ 2.14]）和女孩（OR = 2.45[1.51 ~ 3.97]）的超重患病率与高水平的电视/视频观看呈正相关。在白人男孩（OR = 0.81[0.76至0.87]）、非西班牙裔黑人男孩（OR = 0.86[0.76至0.98]）和女孩（OR = 0.88[0.78至0.99]）中，高水平的中度至剧烈体育活动降低了超重的几率。西班牙裔男孩（OR = 0.90[0.83至0.97]）和女孩（OR = 0.91[0.84至0.99]）。讨论：由逻辑回归模型产生的预测概率。该研究考察了改变看电视/视频的时间和进行中度到剧烈体育活动的实验效果，结果显示，每周看电视较少并经常进行中度到剧烈体育活动的青少年的超重程度低于每周看电视较多并每周进行较少中度到剧烈体育活动的青少年。预测的概率表明，这些关联存在重要的性别和种族差异。
Objective: To examine the relationship between physical activity and inactivity patterns and overweight in U.S. adolescents using baseline and 1-year change in activity and inactivity data.Research Methods and Procedures: Nationally representative data from 12,759 participants (6997 non-Hispanic whites, 2676 non-Hispanic blacks, 2185 Hispanics. and 901 Asians) in the National Longitudinal Study of Adolescent Health (1995 and 1996). Data on moderate to vigorous and low-intensity physical activity, TV/video viewing, and video game/computer use were obtained from questionnaires. Multivariate models assessed the association of overweight (body mass index greater than or equal to 95th percentile Centers for Disease Control and Prevention/National Center for Health Statistics 2000 curves) with initial (and 1-year change) activity and inactivity levels, controlling for age. ethnicity, socioeconomic status, urban residence, cigarette smoking, and region of residence.Results: Overweight prevalence was positively associated with high level TV/video viewing among white boys (odds ratio [OR] = 1.52; 95% confidence interval [1.08 to 2.14]) and girls (OR = 2.45 [1.51 to 3.97]). The odds of overweight decreased with high levels of moderate to vigorous physical activity among white boys (OR = 0.81 [0.76 to 0.87]), non-Hispanic black boys (OR = 0.86 [0.76 to 0.98]) and girls (OR = 0.88 [0.78 to 0.99]). and Hispanic boys (OR = 0.90 [0.83 to 0.97]) and girls (OR = 0.91 [0.84 to 0.99]).Discussion: Predicted probabilities generated from the logistic regression models. which examined the experimental effects of altering hours of TV/video viewing and bouts of moderate to vigorous physical activity, show lower overweight among adolescents who watched less TV per week combined with frequent moderate to vigorous physical activity than those who watched more TV per week combined with fewer bouts of weekly moderate to vigorous physical activity. Predicted probabilities suggest important sex and ethnic differences in these associations.
