The relation between physical activity and renal cell cancer is unclear. High occupational physical activity has been associated with a decreased risk of renal cell cancer among men-but not among women-in two previous studies, while no association has been found for leisure time physical activity. Our aim was to investigate the association between occupational and leisure time physical activity in a prospective cohort of 17,241 Swedish twins. Information on physical activity and a wide range of potential confounding factors was obtained through a mailed questionnaire. During follow-up from 1967 through 1997 we identified 102 cases of renal cell cancer. We found no evidence of an inverse association between either occupational or leisure time physical activity and risk of renal cell cancer in this prospective cohort.
体力活动与肾细胞癌之间的关系尚不清楚。在之前的两项研究中，高强度职业体力活动与男性肾细胞癌风险降低相关，但与女性无关，而休闲时间体力活动与肾细胞癌风险未发现关联。我们的目的是在一个由17241名瑞典双胞胎组成的前瞻性队列中，研究职业和休闲时间体力活动之间的关联。通过邮寄问卷获取了有关体力活动和一系列潜在混杂因素的信息。在1967年至1997年的随访期间，我们确定了102例肾细胞癌病例。在这个前瞻性队列中，我们没有发现职业或休闲时间体力活动与肾细胞癌风险之间存在负相关的证据。
