物理距离和其他COVID-19大流行缓解策略可能会对许多健康行为和健康结果产生意想不到的后果。本研究的目的是在一对成年双胞胎样本中调查身体活动或锻炼的感知变化与短期心理健康结果之间的关联，以应对COVID-19缓解策略。方法这是一项横断面研究，来自社区华盛顿州双胞胎登记处的3,971对同卵和同性异卵成年双胞胎（909对，77%相同）。这项研究的参与者完成了一项在线调查，调查了2020年3月26日至4月5日期间COVID-19缓解对一些健康相关行为和结果的影响。在本研究中，暴露是身体活动或锻炼的感知变化。结果是感知的焦虑和压力水平。结果更多的双胞胎报告身体活动水平下降（42%），而不是那些报告没有变化（31%）或增加身体活动水平（27%）。身体活动或锻炼的减少与更高的压力和焦虑水平有关。然而，体力活动压力的关系是混淆遗传和共享的环境因素。另一方面，在控制了遗传和共享环境因素后，身体活动与焦虑的关系仍然存在，尽管在进一步控制了年龄和性别后，这种关系不再显著，年龄较大的双胞胎更有可能报告较低水平的焦虑，而女性更有可能报告较高水平的焦虑。缓解COVID-19大流行的策略可能会影响身体活动和心理健康，那些身体活动减少的人也会有更高的压力和焦虑。这些关系受到遗传和共同环境因素的干扰，在压力的情况下，年龄和性别，在焦虑的情况下。
Background Physical distancing and other COVID-19 pandemic mitigation strategies may have unintended consequences on a number of health behaviors and health outcomes. The purpose of this study was to investigate the association between perceived change in physical activity or exercise and mental health outcomes over the short-term in response to COVID-19 mitigation strategies in a sample of adult twins. Methods This was a cross-sectional study of 3,971 identical and same-sex fraternal adult twins (909 pairs, 77% identical) from the community-based Washington State Twin Registry. Participants in this study completed an online survey examining the impact of COVID-19 mitigation on a number of health-related behaviors and outcomes, administered between March 26 and April 5, 2020. In the present study, the exposure was perceived change in physical activity or exercise. The outcomes were levels of perceived anxiety and stress. Results More twin pairs reported a decrease in physical activity levels (42%) than those reporting no change (31%) or increased physical activity levels (27%). A perceived decrease in physical activity or exercise was associated with higher stress and anxiety levels. However, the physical activity-stress relationship was confounded by genetic and shared environmental factors. On the other hand, the physical activity-anxiety relationship held after controlling for genetic and shared environmental factors, although it was no longer significant after further controlling for age and sex, with older twins more likely to report lower levels of anxiety and females more likely to report higher levels of anxiety. Conclusions Strategies to mitigate the COVID-19 pandemic may be impacting physical activity and mental health, with those experiencing a decrease in physical activity also having higher levels of stress and anxiety. These relationships are confounded by genetic and shared environmental factors, in the case of stress, and age and sex, in the case of anxiety.
