Abstract

Background— Television viewing time, the predominant leisure-time sedentary behavior, is associated with biomarkers of cardiometabolic risk, but its relationship with mortality has not been studied. We examined the associations of prolonged television viewing time with all-cause, cardiovascular disease (CVD), cancer, and non-CVD/noncancer mortality in Australian adults. Methods and Results— Television viewing time in relation to subsequent all-cause, CVD, and cancer mortality (median follow-up, 6.6 years) was examined among 8800 adults ≥25 years of age in the Australian Diabetes, Obesity and Lifestyle Study (AusDiab). During 58 087 person-years of follow-up, there were 284 deaths (87 CVD deaths, 125 cancer deaths). After adjustment for age, sex, waist circumference, and exercise, the hazard ratios for each 1-hour increment in television viewing time per day were 1.11 (95% confidence interval [CI], 1.03 to 1.20) for all-cause mortality, 1.18 (95% CI, 1.03 to 1.35) for CVD mortality, and 1.09 (95% CI, 0.96 to 1.23) for cancer mortality. Compared with a television viewing time of <2 h/d, the fully adjusted hazard ratios for all-cause mortality were 1.13 (95% CI, 0.87 to 1.36) for ≥2 to <4 h/d and 1.46 (95% CI, 1.04 to 2.05) for ≥4 h/d. For CVD mortality, corresponding hazard ratios were 1.19 (95% CI, 0.72 to 1.99) and 1.80 (95% CI, 1.00 to 3.25). The associations with both cancer mortality and non-CVD/noncancer mortality were not significant. Conclusions— Television viewing time was associated with increased risk of all-cause and CVD mortality. In addition to the promotion of exercise, chronic disease prevention strategies could focus on reducing sitting time, particularly prolonged television viewing.

  • In 20,000 Australians, every additional hour of TV viewing raised all-cause death risk by 11% and CVD death risk by 18%.

    “Dunstan et al. (151) found that each 1-hour increase in TV viewing time was associated with 11% and 18% increased risks of all-cause and CVD mortality, respectively, in 20,000 Australian men and women.”

  • Watching more than 4 hours of TV daily versus less than 2 was linked to 46% higher all-cause and 80% higher CVD mortality, independent of smoking, blood pressure, cholesterol, diet, waist, and leisure exercise.

    “all-cause and CVD mortalities increased 46% and 80%, respectively for TV viewing time >4hr/day as compared to <2 hrs/day, which were independent of smoking, blood pressure, cholesterol, diet, waist circumference, and leisure-time exercise.”

  • The meta-prevalence of sitting was obtained for a total population of 372,550 compiled from seven surveys covering six countries (Australia, Canada, Norway, Spain, UK and USA).

    “These results were obtained for a total population of 372,550 compiled from seven surveys covering six countries (Australia, Canada, Norway, Spain, UK and USA) [3,17,18,24,25,27,33].”
  • 54.2% of older adults report watching over 3 h of TV per day.

    “Fifty six percent of the older population report watching over 2 h of TV per day, 54.2% report over 3 h and 15.1% report over 4 h.”
  • There is little difference in sedentary behavior report by gender, with a mean difference of 1.6 ± 1.6%.

    “It would appear there is little difference in report by gender (1.6 ± 1.6%) [3,17,18].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
