BACKGROUND
Sedentary behavior is associated with cardiovascular disease, diabetes mellitus, and cancer morbidity, and watching television (TV) is an important sedentary behavior. The aim of this study is to clarify the association between TV viewing time and chronic obstructive pulmonary disease (COPD)-related mortality in Japanese adults.
METHODS
Using the Cox proportional hazard model, we assessed COPD-related mortality by TV viewing time in a national cohort of 33 414 men and 43 274 women without cancer, stroke, myocardial infarction, or tuberculosis at baseline (1988-1990).
RESULTS
The median follow-up was 19.4 years; 244 men and 34 women died of COPD. Men watching ≥4 hours/day of TV were more likely to die of COPD than those watching <2 hours/day (hazard ratio 1.63; 95% confidence interval, 1.04-2.55), independent of major confounders. No association was found in women.
CONCLUSIONS
Avoiding a sedentary lifestyle, particularly prolonged TV viewing, may help in preventing death from COPD among men.
背景
久坐行为与心血管疾病、糖尿病和癌症发病相关，而看电视是一种重要的久坐行为。本研究旨在阐明日本成年人看电视时间与慢性阻塞性肺疾病（COPD）相关死亡率之间的关联。
方法
我们使用Cox比例风险模型，在一个全国性队列中，根据看电视时间评估COPD相关死亡率，该队列包括33414名男性和43274名女性，基线时（1988 - 1990年）无癌症、中风、心肌梗死或结核病。
结果
中位随访时间为19.4年；244名男性和34名女性死于COPD。每天看电视≥4小时的男性死于COPD的可能性高于每天看电视<2小时的男性（风险比1.63；95%置信区间，1.04 - 2.55），独立于主要混杂因素。在女性中未发现关联。
结论
避免久坐的生活方式，尤其是长时间看电视，可能有助于预防男性因COPD死亡。
