Little prospective evidence exists about whether a combination of healthy lifestyle factors is related to a considerable reduction of liver cancer risk.
Based on the prospective China Kadoorie Biobank (CKB) cohort with a total of 492,640 Chinese adults, we examined the associations of five lifestyle factors with risk of liver cancer. Low-risk lifestyle factors were defined as non-smoking, non-drinking, median or higher level of physical activity, a healthy diet, and waist-to-hip ratio (WHR) < 0.90 for men and <0.85 for women.
During a median of 10.12 years of follow-up, 2529 liver cancer events were observed. There was a significant decrease in liver cancer risk with the increasing of the healthy lifestyle index scores (P < 0.001). Participants with a favourable lifestyle (4 or 5 healthy lifestyle factors) had a 43% reduced liver cancer risk compared with those with an unfavourable lifestyle (0 or 1 healthy lifestyle factor) (HR, 0.57 [95% CI, 0.47-0.68]). The cumulative protective effect of a healthy lifestyle on liver cancer appeared to be more dramatic for patients with hepatitis B surface antigen (HBsAg) positive, the individuals at high risk of liver cancer.
Individuals adhering to a favourable lifestyle was associated with a considerable absolute risk reduction of liver cancer.
关于健康的生活方式因素组合是否与肝癌风险的显著降低有关,目前几乎没有前瞻性证据。
基于前瞻性的中国慢性病前瞻性研究(CKB)队列,该队列共纳入了 492640 名中国成年人,我们研究了 5 种生活方式因素与肝癌风险的关系。低风险的生活方式因素定义为不吸烟、不饮酒、中等或更高水平的身体活动、健康饮食以及男性腰围臀围比(WHR)<0.90,女性<0.85。
在中位随访 10.12 年期间,观察到 2529 例肝癌事件。肝癌风险随着健康生活方式指数评分的增加而显著降低(P<0.001)。与生活方式不良(0 或 1 个健康生活方式因素)的参与者相比,生活方式良好(4 或 5 个健康生活方式因素)的参与者肝癌风险降低了 43%(HR,0.57[95%CI,0.47-0.68])。健康生活方式对肝癌的累积保护作用对于乙型肝炎表面抗原(HBsAg)阳性、肝癌高危人群的患者似乎更为显著。
坚持健康生活方式与肝癌的绝对风险显著降低有关。
