The purpose of this study was to investigate the association between television (TV) viewing and all-cause mortality among Brazilian adults after 6 years of follow-up. This longitudinal study started in 2010 in the city of Bauru, SP, Brazil, and involved 970 adults aged ≥50 years. Mortality was reported by relatives and confirmed in medical records of the Brazilian National Health System. Physical activity (PA) and TV viewing were assessed by the Baecke questionnaire. Health status, sociodemographic and behavioral covariates were considered as potential confounders. After 6 years of follow-up, 89 deaths were registered (9.2% [95% CI=7.4%-11%]). Type 2 diabetes mellitus was associated with higher risk of mortality (P-value=.012). Deaths correlated significantly with age (ρ=.188; P-value=.001), overall PA score (ρ=-.128; P-value=.001) and TV viewing (ρ=.086; P-value=.007). Lower percentage of participants reported TV viewing time as often (16%) and very often (5.7%), but there was an association between higher TV viewing time ("often" and "very often" grouped together) and increased mortality after 6 years of follow-up (P-value=.006). The higher TV viewing time was associated with a 44.7% increase in all-cause mortality (HR=1.447 [1.019-2.055]), independently of other potential confounders. In conclusion, the findings from this cohort study identified increased risk of mortality among adults with higher TV viewing time, independently of PA and other variables.
本研究的目的是在对巴西成年人进行6年随访后，调查看电视与全因死亡率之间的关联。这项纵向研究于2010年在巴西圣保罗州包鲁市启动，纳入了970名年龄≥50岁的成年人。死亡率由亲属报告，并在巴西国家卫生系统的医疗记录中得到证实。身体活动（PA）和看电视情况通过贝克问卷进行评估。健康状况、社会人口统计学和行为协变量被视为潜在的混杂因素。经过6年的随访，登记了89例死亡（9.2%[95%CI=7.4%-11%]）。2型糖尿病与较高的死亡风险相关（P值=0.012）。死亡与年龄（ρ=0.188；P值=0.001）、总体PA评分（ρ=-0.128；P值=0.001）和看电视（ρ=0.086；P值=0.007）显著相关。报告看电视时间为“经常”（16%）和“非常经常”（5.7%）的参与者比例较低，但在6年随访后，较高的看电视时间（“经常”和“非常经常”合并在一起）与死亡率增加之间存在关联（P值=0.006）。较高的看电视时间与全因死亡率增加44.7%相关（HR=1.447[1.019-2.055]），独立于其他潜在的混杂因素。总之，这项队列研究的结果表明，看电视时间较长的成年人死亡风险增加，独立于PA和其他变量。
