To ascertain whether prolonged television viewing time was associated with lung cancer incidence in Japanese adults aged 40-79 years from a nationwide large-scale cohort study. A total of 54,258 adults (23,090 men and 31,168 women) without a history of cancer at baseline (1988-1990) were enrolled and followed for a median of 15.6 years. The Cox proportional hazard model was used to calculate hazard ratios (HRs) and 95 % confidence interval (CI) for lung cancer according to television viewing time adjusted for age and other possible confounding factors. During the study period, 798 participants were diagnosed with lung cancer. The HR of male participants who watched television for more than 4 h daily was 1.36 (95 % CI 1.04-1.80) compared with < 2 h/day. Our findings suggest that reducing the amount of time spent watching television may be beneficial for preventing lung cancer.
