Abstract
OBJECTIVES: Sleep health and other lifestyle behaviours are gaining increasing attention in public health, particularly for cancer prevention, but a comprehensive assessment is lacking. METHODS: The study included 380,042 UK Biobank participants. A healthy sleep score was constructed based on five sleep factors: chronotype, sleep duration, insomnia, snoring, and daytime dozing. A healthy lifestyle score was constructed based on four lifestyle factors: smoking, alcohol consumption, diet and physical activity. The effect of healthy sleep and lifestyle on cancer risk was examined by Cox proportional hazard models. RESULTS: Both healthy sleep and lifestyle patterns were significantly associated with a reduced risk of overall cancer and specific cancer sites. Participants with healthy sleep and lifestyle patterns had a lower risk of overall cancer (HR = 0.72, 95% CI = 0.68-0.77), liver cancer (HR = 0.53, 95% CI = 0.31-0.90), bladder cancer (HR = 0.61, 95% CI = 0.47-0.79), lung cancer (HR = 0.22, 95% CI = 0.19-0.27), and colorectal cancer (HR = 0.80, 95% CI = 0.66-0.96) compared to those with unhealthy patterns. CONCLUSION: Our findings highlight the importance of public health education and interventions to improve sleep and other lifestyle behaviours for cancer prevention.
