The current study investigated the relationship between the frequency of watching sports and depressive symptoms among older adults. This study used cross-sectional data from the Japan Gerontological Evaluation Study, a nationwide mail survey of 21,317 older adults. Depressive symptoms were defined as a Geriatric Depression Scale score of ≥ 5. Participants were queried regarding the average frequency at which they watched sports on-site and via TV/Internet over the past year. Among the 21,317 participants, 4559 (21.4%) had depressive symptoms, while 4808 (22.6%) and 16,576 (77.8%) watched sports on-site and via TV/Internet at least once a year, respectively. Older adults who watched sports on-site a few times/year (prevalence ratio, 0.70; 95% confidence interval, 0.65-0.74) or 1-3 times/month (0.66, 0.53-0.82) were less likely to have depressive symptoms compared to non-spectators after adjusting for frequency of playing sports, exercise activities, and other potential confounders. Meanwhile, a dose-response relationship was confirmed for watching via TV/Internet (prevalence ratio of 0.86, 0.79, and 0.71 for a few times/year, 1-3 times/month, and ≥ 1 time/week, respectively). This study suggested that watching sports on-site or via TV/Internet, regardless of whether they regularly engage in sports, may reduce the risk of depressive symptoms among older adults.
本研究调查了观看体育活动频率与老年人抑郁症状之间的关系。本研究使用了日本老年评估研究的横断面数据,这是一项针对 21317 名老年人的全国性邮件调查。抑郁症状的定义为老年抑郁量表评分≥5 分。参与者被询问过去一年中平均观看现场和通过电视/互联网观看体育活动的频率。在 21317 名参与者中,4559 人(21.4%)有抑郁症状,而 4808 人(22.6%)和 16576 人(77.8%)分别至少每年现场观看和通过电视/互联网观看体育活动一次。与非观众相比,每年现场观看几次(流行率比,0.70;95%置信区间,0.65-0.74)或每月 1-3 次(0.66,0.53-0.82)的老年人发生抑郁症状的可能性较低,调整了运动频率、运动活动和其他潜在混杂因素后。同时,通过电视/互联网观看也证实了剂量反应关系(流行率比分别为 0.86、0.79 和 0.71,每年几次、每月 1-3 次和每周至少 1 次)。本研究表明,现场观看或通过电视/互联网观看体育活动,无论是否经常参加体育活动,都可能降低老年人患抑郁症状的风险。
