Depression is a prevalent, debilitating, and often recurrent mood disorder for which successful first-line treatments remains limited. The purpose of this study was to investigate the cross-sectional associations between self-reported physical activity (PA) and depressive symptoms and status among Irish adults, using two existing datasets, The Irish Longitudinal Study on Ageing (TILDA) and The Mitchelstown Cohort Study.
The two selected databases were pooled (n = 10,122), and relevant variables were harmonized. PA was measured using the short form International Physical Activity Questionnaire. Depressive symptoms were measured by the Center for Epidemiologic Studies Depression (CES-D) questionnaire. Participants were classified as meeting World Health Organization moderate-to-vigorous PA (MVPA) guidelines or not, and divided into tertiles based on weekly minutes of MVPA. A CES-D score of ≥16 indicated elevated depressive symptoms. Data collection were conducted in 2010-2011.
Significantly higher depressive symptoms were reported by females (7.11 ± 7.87) than males (5.74 ± 6.86; p < 0.001). Following adjustment for age, sex, BMI, and dataset, meeting the PA guidelines was associated with 44.7% (95%CI: 35.0 to 52.9; p < 0.001) lower odds of elevated depressive symptoms. Compared to the low PA tertile, the middle and high PA tertiles were associated with 25.2% (95%CI: 8.7 to 38.6; p < 0.01) and 50.8% (95%CI: 40.7 to 59.2; p < 0.001) lower odds of elevated depressive symptoms, respectively.
Meeting the PA guidelines is associated with lower odds of elevated depressive symptoms, and increased volumes of MVPA are associated with lower odds of elevated depressive symptoms.
抑郁症是一种普遍存在、使人虚弱且常常反复发作的情绪障碍，目前成功的一线治疗方法仍然有限。本研究的目的是通过两项现有的数据库（爱尔兰老龄化纵向研究（TILDA）和米切尔斯顿队列研究），调查爱尔兰成年人中自我报告的体力活动（PA）与抑郁症状和状况之间的横断面关联。
将这两个选定的数据库合并（n=10122），并协调相关变量。使用短形式国际体力活动问卷测量 PA。使用流行病学研究中心抑郁量表（CES-D）问卷测量抑郁症状。根据每周中等至剧烈体力活动（MVPA）的分钟数，将参与者分为符合或不符合世界卫生组织 MVPA 指南的类别，并分为三分位。CES-D 得分≥16 表示存在较高的抑郁症状。数据收集于 2010-2011 年进行。
女性（7.11±7.87）报告的抑郁症状明显高于男性（5.74±6.86；p<0.001）。在调整年龄、性别、BMI 和数据库后，符合 PA 指南与升高的抑郁症状的可能性降低 44.7%（95%CI：35.0 至 52.9；p<0.001）相关。与低 PA 三分位相比，中 PA 三分位和高 PA 三分位与升高的抑郁症状的可能性降低 25.2%（95%CI：8.7 至 38.6；p<0.01）和 50.8%（95%CI：40.7 至 59.2；p<0.001）相关。
符合 PA 指南与升高的抑郁症状的可能性降低相关，而增加 MVPA 量与降低升高的抑郁症状的可能性相关。
