Military service members carry the responsibility to maintain physical and psychological readiness. As such, it is critical for researchers to begin unravelling the widespread impact of the COVID-19 pandemic on service member's mental and physical wellbeing. The aim of this research was to investigate the complex relationships between BMI, physical activity, psychological stress and resilience among United States Air National Guardsmen (USANG), specifically during the pandemic.
An online survey was distributed to USANG members. The survey included measures of resilience (CD-RISC-25), perceived psychological stress (PSS), perceived psychological stress brought on by COVID-19 (COVID-19 PSL), current levels of physical activity (IPAQ-SF), perceived impact on physical activity brought on by COVID-19 (COVID-19 PAL), and BMI. Pearson's correlation coefficients (r) were used to assess correlation significance ( ≤ 0.05), direction, and magnitude.
A total of 110 responses met inclusion criteria for data interpretation. A majority reported a decline in physical activity 54.5%, while 60% reported an increase in psychological stress. According to BMI classifications, 60.9% were considered overweight or obese. Seven meaningful (effect size ≥ |2.0|) and statistically significant salient associations were identified resilience-PSS r = -0.38; resilience-COVID-19 PAL r = 0.21; PSS-COVID-19 PSL r = 0.35; PSS-COVID-19 PAL r = -0.23; COVID-19 PSL COVID-19 PAL r = -0.24; IPAQ-SF-BMI r = -0.23; BMI-Covid-19 PAL r = -0.32.
Key outcomes suggest resilience is inversely associated with assessed and perceived stress, resilience may influence health-related behaviour which subsequently might aid as a protective factor against psychological stress. Knowledge regarding the relationships between the aforementioned variables may help inform decisions by military leadership regarding future lockdowns.
军人肩负着保持身体和心理准备状态的责任。因此，研究人员开始揭示新冠疫情对军人身心健康的广泛影响至关重要。本研究的目的是调查美国空军国民警卫队（USANG）成员中体重指数（BMI）、身体活动、心理压力和恢复力之间的复杂关系，特别是在疫情期间。
向USANG成员发放了一份在线调查问卷。该问卷包括恢复力测量（CD-RISC-25）、感知心理压力（PSS）、新冠疫情带来的感知心理压力（COVID-19 PSL）、当前身体活动水平（IPAQ-SF）、新冠疫情对身体活动的感知影响（COVID-19 PAL）以及BMI。使用皮尔逊相关系数（r）来评估相关性的显著性（≤0.05）、方向和大小。
共有110份回复符合数据解读的纳入标准。大多数人报告身体活动减少（54.5%），而60%的人报告心理压力增加。根据BMI分类，60.9%的人被认为超重或肥胖。确定了七个有意义（效应大小≥|2.0|）且具有统计学显著性的显著关联：恢复力-PSS r = -0.38；恢复力-COVID-19 PAL r = 0.21；PSS-COVID-19 PSL r = 0.35；PSS-COVID-19 PAL r = -0.23；COVID-19 PSL-COVID-19 PAL r = -0.24；IPAQ-SF-BMI r = -0.23；BMI-Covid-19 PAL r = -0.32。
关键结果表明，恢复力与评估和感知到的压力呈负相关，恢复力可能会影响与健康相关的行为，这随后可能作为抵御心理压力的保护因素。关于上述变量之间关系的知识可能有助于军事领导层就未来的封锁措施做出决策。
