目的：分析肥胖患病率最高的西班牙地中海地区看电视 (TV) 的时间和体力活动与肥胖之间的关系。设计：横断面研究。地点：西班牙巴伦西亚地区。参与者：参加 1994 年进行的健康和营养调查的 814 名男性和 958 名女性的代表性样本，年龄为 15 岁及以上。测量：在家庭访谈中直接测量身高和体重。结果指标是肥胖，定义为体重指数大于或等于 30 kg/m(2)。协变量是自我报告的看电视时间、体育活动习惯、睡眠时间、年龄、性别、教育水平、吸烟和婚姻状况。通过逻辑回归估计的患病率比值比 (POR) 被用作效果测量。 结果：据报道，与非肥胖者（每天 3.0 +/- 1.4 小时）相比，肥胖者看电视的时间更长（平均值 +/- 标准差：3.6 +/- 1.5 小时/天），睡眠时间也更少。在多变量分析中，肥胖与看电视、睡眠时间和工作时的体力活动有关。与每天看电视少于或等于 1 小时的人相比，每天看电视时间大于或等于 4 小时的人显示出更高的调整后肥胖患病率比值比，POR = 2.38（95% 置信区间，1.54-3. 69）。每天睡眠时间大于或等于 9 小时的人的肥胖 FOR 值低于每天睡眠时间小于或等于 6 小时的人，FOR = 0.43 (0.27 -9.67)。这两种关联都观察到了统计学上显着的剂量反应，因此看电视时间每增加一小时，肥胖患病率比值就会升高 30%，睡眠时间每增加一小时，肥胖患病率就会降低 24%。此外，单身人士、工作中体力活动较多的人和受教育程度较高的人的肥胖患病率最低。结论：看电视的时间和工作中体力活动较少与成人肥胖有关。肥胖与睡眠时间之间的负相关值得进一步研究。
OBJECTIVE: To analyse the association of time watching television (TV) and physical activity with obesity in the Mediterranean area of Spain with the highest prevalence of obesity.DESIGN: Cross-sectional study.SETTING: Valencia Region in Spain.PARTICIPANTS: A representative sample of 814 men and 958 women, aged 15 y and older, participating in a Health and Nutrition Survey conducted in 1994.MEASUREMENTS: Height and weight were directly measured during home interviews. The outcome measure was obesity, defined as a body mass index greater than or equal to 30 kg/m(2). Covariates were self-reported hours of TV viewing, physical activity habits, sleeping duration, age, gender, educational level, smoking and marital status. Prevalence odds ratios (POR) estimated by logistic regression were used as effect measures.RESULTS: Obese people reported to spend more time watching TV (mean +/- s.d.: 3.6 +/- 1.5 h/day) than non-obese ones (3.0 +/- 1.4 h/day), and less sleeping time. In multivariate analysis, obesity was associated with TV viewing, sleeping time and physical activity at work. People watching TV greater than or equal to4 h/day showed a higher adjusted prevalence odds ratio of obesity, POR = 2.38 (95% confidence interval, 1.54-3. 69), compared with those watching TV less than or equal to1 h/day. People who reported to sleep greater than or equal to9 h/day presented a lower FOR of obesity than those sleeping less than or equal to6 h/day, FOR = 0.43 (0.27 -9.67). Statistically significant dose-responses were observed for both associations, so that the prevalence odds ratio of obesity was 30% higher for each hour of increased TV Viewing and 24% lower for each additional hour of sleeping time. in addition, the prevalence of obesity was lowest among single people, those more physically active at work, and those with a high educational level.CONCLUSION: Time spent watching television and a low physical activity at work were related to obesity in adults. The inverse association between obesity and sleep duration deserves further research.
