Depression is a serious mental condition and physical activity is known to be effective in alleviating it. This study for rural residents of South Korea investigated whether meeting the recommended amount of physical activity during leisure time (LTPA) can reduce the depressive symptoms.
A prospective study was conducted with 5,178 participants aged 20 years and over, and we analyzed 1,888 participants excluding those diagnosed with depression at baseline and those with insufficient data after an average of 5.3 years of follow-up. LTPA was quantified by the MET (metabolic equivalent of task) and categorized according to whether the recommended physical activity was met (0, 0.1 to < 7.5, ≥ 7.5 MET h/wk). The relationship with depressive symptoms (CES-D ≥ 41) was generated by adjusted relative risks (RRs) and 95% CIs through multivariate logistic regression.
During the followed-up, 100 (5.3%) participants developed depressive symptoms. Compared to the incidence of depressive symptoms in those who did not perform any LTPA (6.8%), it was significantly lower when the recommended physical activity criteria were met by combining moderate intensity (MET 3 to 6) and vigorous intensity (MET ≥ 6) exercise (3.3%). We observed a 43.7% lower risk of depressive symptoms among those performing more than the recommended minimum (RR, 0.563 [95% CI, 0.341-0.930]) than those who had no LTPA.
This study did not address psychosocial factors, and physical activities in daily life and the occupational environment were not considered.
Performing adequate LTPA might be advisable to alleviate depressive symptoms.
抑郁症是一种严重的精神疾病，运动已被证实对其具有缓解作用。本研究针对韩国农村居民，旨在探讨休闲时间内是否达到推荐的运动量（LTPA）是否可以减轻抑郁症状。
采用前瞻性研究方法，对 5178 名 20 岁及以上的参与者进行分析，排除基线时患有抑郁症的患者和随访平均 5.3 年后数据不足的患者，最终纳入 1888 名参与者。LTPA 通过代谢当量（MET）进行量化，并根据是否达到推荐的运动量（0、0.1 至<7.5、≥7.5MET h/wk）进行分类。通过多变量逻辑回归生成与抑郁症状（CES-D≥41）的关系，采用调整后的相对风险（RR）和 95%置信区间（CI）进行表示。
在随访期间，有 100 名（5.3%）参与者出现抑郁症状。与未进行任何 LTPA 的参与者（6.8%）相比，达到推荐的运动量标准，即中等强度（MET 3 至 6）和高强度（MET≥6）运动相结合时，抑郁症状的发生率显著降低（3.3%）。与没有 LTPA 的人相比，进行超过推荐最小运动量的人出现抑郁症状的风险降低了 43.7%（RR，0.563[95%CI，0.341-0.930]）。
本研究未考虑心理社会因素，也未考虑日常生活和职业环境中的体力活动。
进行足够的 LTPA 可能有助于缓解抑郁症状。
