As sodium, potassium and fluid intake are related to hypertension, an established risk factor for renal cell cancer (RCC), they may be independent risk factors for RCC.
The Netherlands Cohort Study (NLCS) with case-cohort design included 120,852 participants aged 55-69 years. At baseline, diet and lifestyle were assessed with questionnaires. After 17.3 years of follow-up, 485 RCC cases and 4438 subcohort members were available for analyses.
Sodium intake increased RCC risk (P-trend=0.03), whereas fluid and potassium intake did not. For high sodium and low fluid intake, the RCC risk additionally increased (P-interaction=0.02).
Sodium intake is a potential risk factor for RCC, particularly if fluid consumption is low.
钠、钾和液体摄入量与高血压有关,高血压是肾细胞癌(RCC)的一个既定风险因素,因此它们可能是 RCC 的独立风险因素。
采用病例-队列设计的荷兰队列研究(NLCS)纳入了 120852 名年龄在 55-69 岁的参与者。在基线时,通过问卷评估饮食和生活方式。随访 17.3 年后,有 485 例 RCC 病例和 4438 名亚队列成员可用于分析。
钠摄入量增加了 RCC 风险(P 趋势=0.03),而液体和钾摄入量没有。对于高钠和低液体摄入,RCC 风险进一步增加(P 交互=0.02)。
钠摄入量是 RCC 的一个潜在风险因素,特别是如果液体摄入较低。
