Physical activity (PA), television time (TV), and sleep duration (SLP) are considered individual risk factors for adolescent obesity. Our aim was to investigate the concurrent influence of meeting PA, SLP, and TV recommendations on adolescent obesity utilizing 2011 Youth Risk Behavior Surveillance Survey (YRBSS) data.
Subjects included 9589 (4874 females) high school students. PA, SLP, and TV were categorized utilizing established national recommendations and youth were cross-tabulated into 1 of 8 groups based on meeting or not meeting each recommendation. Logistic models were used to examine the odds of obesity for each group.
Youth meeting the PA recommendation were not at increased odds of obesity, regardless of SLP or TV status. However, not meeting any single recommendation, in general, led to increased odds of not meeting the other two. In boys, 11.8% met all recommendations while 14.1% met 0 recommendations. In girls, only 5.0% met all recommendations while 17.8% met none.
Boys and girls not meeting any of the recommendations were 4.0 and 3.8 times more likely to be obese compared with their respective referent groups. Further research considering the simultaneous influence these risk factors may have on obesity and on one another is warranted.
身体活动（PA）、看电视时间（TV）和睡眠时间（SLP）被认为是青少年肥胖的个体风险因素。我们的目的是利用2011年青少年风险行为监测调查（YRBSS）数据，研究达到PA、SLP和TV建议对青少年肥胖的同时影响。
研究对象包括9589名（4874名女性）高中生。根据既定的国家建议对PA、SLP和TV进行分类，并根据是否符合每项建议将青少年交叉分类为8组中的1组。使用逻辑模型检查每组肥胖的几率。
无论SLP或TV状况如何，达到PA建议的青少年肥胖几率并未增加。然而，一般来说，未符合任何一项建议会导致未符合其他两项建议的几率增加。在男孩中，11.8%的人符合所有建议，而14.1%的人一项建议都未符合。在女孩中，只有5.0%的人符合所有建议，而17.8%的人一项都未符合。
与各自的参照组相比，未符合任何一项建议的男孩和女孩肥胖的可能性分别高出4.0倍和3.8倍。有必要进一步研究这些风险因素可能对肥胖以及彼此之间的同时影响。
