BACKGROUND
Television (TV) viewing has been associated with obesity although the effects of specific TV content on health and other behaviours remains unknown. We examined the association between watching sport on TV, physical activity levels, and risk of obesity.
METHODS
We studied 6,733 (aged 64.9 ± 9.2 yrs) men and women from the English Longitudinal Study of Ageing, a prospective study of community dwelling older adults. Data were collected on self reported TV time and content, and physical activity. Nurses measured height and weight for the calculation of body mass index.
RESULTS
On average, participants reported viewing TV for 5.3 ± 4.1 hours per day and 30.3% of the sample watched sport on TV at least twice a week. There was no association between watching sport and physical activity levels. Participants that watched sports every day were at higher risk of obesity [odds ratio = 1.39, 95% CI, 1.15, 1.68) after adjustment for age, sex, smoking, alcohol, physical activity, total TV time, disability, and self-rated health.
CONCLUSIONS
Watching elite athletes may have no role in the promotion of physical activity in older adults, which has implications for staging large sporting events with physical activity legacy promises.
背景
尽管特定电视内容对健康和其他行为的影响尚不清楚，但看电视已被认为与肥胖有关。我们研究了观看体育电视节目、身体活动水平与肥胖风险之间的关联。
方法
我们对来自英国老龄化纵向研究的6733名（年龄64.9±9.2岁）男性和女性进行了研究，该研究是一项针对社区居住老年人的前瞻性研究。收集了关于自我报告的看电视时间和内容以及身体活动的数据。护士测量身高和体重以计算体重指数。
结果
参与者平均每天报告看电视5.3±4.1小时，30.3%的样本每周至少观看两次体育电视节目。观看体育节目与身体活动水平之间没有关联。在对年龄、性别、吸烟、饮酒、身体活动、总看电视时间、残疾状况和自我健康评分进行调整后，每天观看体育节目的参与者肥胖风险更高[比值比=1.39,95%置信区间,1.15,1.68]。
结论
观看精英运动员比赛可能对促进老年人身体活动没有作用，这对举办承诺留下身体活动遗产的大型体育赛事具有启示意义。
