越来越多的证据表明,体力活动在肾癌(RCC)的发病机制中起着重要作用。然而,目前尚不清楚久坐是否是肾癌的独立危险因素,因为久坐被认为与适度剧烈的体力活动太少不同。在美国国立卫生研究院-AARP饮食和健康研究中,作者前瞻性地研究了289,512名女性和男性久坐与肾癌风险的关系。从1996年到2006年,共发现1206例浸润性肾细胞癌病例。用COX比例风险回归估计多因素危险比(HR)和95%可信区间(CI)。在控制了肾癌的已知危险因素后,我们没有发现肾癌风险与每天坐着看电视或视频的时间(HR7+小时:1小时:0.9(0.66,1.38),P趋势=0.707)或总坐着时间(HR9+小时:3小时:1.11(0.87,1.41),P趋势=0.765)之间存在关联的证据。在这个庞大的队列中,男性和女性中,延长坐着时间与肾癌风险无关。
Accumulating evidence suggests an etiologic role in renal cell carcinoma (RCC) for physical activity. However, it is unknown if prolonged sitting, which is thought to be distinct from too little moderate-vigorous physical activity, is an independent risk factor for RCC. The authors prospectively examined the relationship of prolonged sitting and risk of RCC among 289,512 women and men in the National Institutes of Health—AARP Diet and Health Study. From 1996 through 2006, 1206 invasive RCC cancer cases were identified. Cox proportional hazards regression was used to estimate multivariate hazard ratios (HR) and 95% confidence intervals (CI). After controlling for known risk factors for RCC, we did not find evidence of associations between RCC risk and time spent per day sitting while watching television or videos (HR7+hrs:<1 hr: 0.96 (0.66, 1.38), ptrend=0.707) or total sitting time (HR9+hrs: <3hrs: 1.11 (0.87, 1.41), ptrend=0.765). Prolonged sitting time was not associated with RCC risk among men and women in this large cohort.
