Abstract
AIMS
We examined the association between television (TV) viewing time and all-cause and cardiovascular disease (CVD) mortality among Japanese adults with and without a history of stroke or myocardial infarction (MI).
METHODS
In the Japan Collaborative Cohort Study, 76,572 participants (851 stroke survivors, 1,883 MI survivors, and 73,838 persons without a history of stroke or MI), aged 40-79 years at baseline (1988-1990), completed a lifestyle, diet, and medical history questionnaire, and were followed up regarding mortality until 2009. The Cox proportional hazard model was used to calculate the multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of all-cause and CVD mortality.
RESULTS
During the 19.3-year median follow-up period, 17,387 deaths were documented. TV viewing time was positively associated with all-cause and CVD mortality regardless of stroke or MI history. The multivariable-adjusted HRs of all-cause mortality with 95% CIs for TV viewing time of 3-4.9 h, 5-6.9 h, and ≥ 7 h were 1.18 (0.95-1.48), 1.12 (0.86-1.45), and 1.61 (1.12-2.32) for stroke survivors; 0.97 (0.81-1.17), 1.40 (1.12-1.76), and 1.44 (1.02-2.03) for MI survivors; and 1.00 (0.96-1.03), 1.07 (1.01-1.12), and 1.22 (1.11-1.34) for persons without a history of stroke or MI, respectively, compared with <3 h.
CONCLUSIONS
Prolonged TV viewing time was associated with higher risks of all-cause and CVD mortality in stroke or MI survivors and in persons without a history of them. It may be recommended to reduce sedentary time for stroke or MI survivors, independent of the level of physical activity.
