OBJECTIVES
This study undertook to examine relationships between nonsedentary activity level, time spent watching television (TV)/videocassette recorder (VCR), and risk of overweight among men.
METHODS
Men participating in the Health Professionals Follow-Up Study were mailed surveys. Cross-sectional analyses examined the prevalence and odds of being overweight, prospective analyses determined cumulative incidence rates and relative risks of becoming overweight over 2 years of follow-up.
RESULTS
Cross-sectionally, odds of being overweight were 50% (95% confidence interval [CI] = 45%; 55%) lower for men in the highest quintile of nonsedentary activity level when compared with men in the lowest quintile. Among men watching 41 or more hours of TV/VCR per week, the odds of being overweight were 406 (95% CI = 2.67, 6.17) times greater than those for men watching no more than 1 hour per week. Prospectively, higher levels is of nonsedentary activity and lower levels of TV/VCR viewing were independently associated with lower relative risks for becoming overweight between survey years.
CONCLUSIONS
Both a lack of nonsedentary activity and time spent watching TV/VCR contribute to the development of overweight in men. Sedentary and nonsedentary activities represent separate domains, each with independent risks for overweight.
目的
本研究旨在探讨男性非久坐活动水平、看电视/录像带时间与超重风险之间的关系。
方法
向参与健康专业人员随访研究的男性邮寄调查问卷。横断面分析研究超重的患病率和几率，前瞻性分析确定随访2年期间超重的累积发病率和相对风险。
结果
横断面研究中，与非久坐活动水平最低的五分位数男性相比，最高五分位数男性超重的几率降低了50%（95%置信区间[CI]=45%；55%）。每周看电视/录像带41小时或更长时间的男性超重几率比每周看电视/录像带不超过1小时的男性高4.06倍（95%CI=2.67，6.17）。前瞻性研究中，非久坐活动水平较高和看电视/录像带时间较短与随访期间超重的相对风险较低独立相关。
结论
缺乏非久坐活动和看电视/录像带时间过长均会导致男性超重。久坐和非久坐活动是不同的领域，各自具有超重的独立风险。
