In March 2020, the Spanish government established an official lockdown across the country in response to the COVID-19 pandemic and confined the population to their homes, restricting their mobility. The objectives of the study are twofold: a) to examine dose-response relationships between physical activity (PA) components (volume, intensity, frequency, duration) and depressive symptoms of the population during confinement, and b) to identify the optimal levels of PA to mitigate notable depressive symptoms (NDS).
4,811 (2,952 women) Spanish citizens, age range 16-92 years, completed an online questionnaire (snowball sampling) to measure their levels of depressive symptoms, PA, and various anthropometric and sociometric variables. Volume (METs-min/week), frequency (days/week), and duration (hours) were examined using logistic regressions with restricted cubic splines.
The PA components were inversely associated with NDS. Performing at least 477 METs-min/week was associated with a 33% decrease in probability of NDS, and reaching 3,000 METs-min/week was associated with the lowest risk of NDS (47%). As for frequency, with 10 times/week the probability of NDS was 56% lower. At 10 hours of weekly practice, the probability of NDS was 39% lower.
A range and optimal amount of PA is suggested to reduce the appearance of SDN during confinement.
2020 年 3 月，西班牙政府为应对 COVID-19 疫情在全国范围内实施了正式封锁，将民众限制在家中，限制其行动。本研究的目的有两个：a）研究人群在禁闭期间的体力活动（PA）各成分（量、强度、频率、持续时间）与抑郁症状之间的剂量反应关系，b）确定最佳的 PA 水平以减轻明显的抑郁症状（NDS）。
4811 名（2952 名女性）年龄在 16-92 岁的西班牙公民通过在线问卷（雪球抽样）完成了对抑郁症状、PA 以及各种人体测量学和社会学变量的测量。使用逻辑回归和限制性立方样条分析体积（METs-min/周）、频率（周/天）和持续时间（小时）。
PA 各成分与 NDS 呈负相关。每周进行至少 477 METs-min/周与 NDS 发生概率降低 33%相关，达到 3000 METs-min/周与 NDS 发生风险最低相关（47%）。就频率而言，每周 10 次时 NDS 的发生概率降低 56%。每周 10 小时时，NDS 的发生概率降低 39%。
建议进行一定范围和适量的 PA，以减少禁闭期间 SDN 的出现。
