Associations between physical activity (PA) and subclinical anxiety disorder symptoms and status, and potential mediating effect of social physique anxiety (SPA), remain understudied. We examined associations between PA and analogue Generalized Anxiety Disorder (AGAD), analogue Social Anxiety Disorder (ASAD), and analogue Panic Disorder (APD) symptoms and status, the mediating effect of SPA, and sex-related differences.
Participants (n = 470, 23.2 ± 4.8 years, 298 female) completed the Psychiatric Diagnostic Screening Questionnaire, seven-day PA recall, and Social Physique Anxiety Scale. ANCOVA examined differences in SPA and anxiety disorder symptoms between PA levels. Logistic regression examined associations between PA and analogue anxiety disorder status. Mediation analyses estimated the effect of change in PA on analogue anxiety disorder odds when SPA was at its mean.
AGAD, ASAD, and APD prevalence was 38.1%, 60.0%, and 15.1%, respectively. AGAD and ASAD symptoms, but not APD symptoms, were significantly lower among higher PA levels. PA was associated with lower odds of AGAD, ASAD, and APD; findings were not significant after adjustment. The pure indirect effect of SPA significantly accounted for 58.2% and 47.9% of the total effect of PA on AGAD and ASAD, respectively; findings were not significant after adjusting for depression. Females showed greater odds of AGAD, ASAD, and APD; mediation findings did not differ based on gender.
Cross-sectional design, self-reported exposure and outcomes, and sample size are potential limitations.
Symptoms and odds of AGAD and ASAD status were lower among young adults with greater PA; SPA partially mediated associations and warrants experimental investigation.
体力活动（PA）与亚临床焦虑障碍症状和状态之间的关系，以及社交身体焦虑（SPA）的潜在中介作用，仍有待研究。我们研究了 PA 与模拟广泛性焦虑障碍（AGAD）、模拟社交焦虑障碍（ASAD）和模拟惊恐障碍（APD）症状和状态之间的关系，SPA 的中介作用，以及与性别相关的差异。
参与者（n=470，23.2±4.8 岁，298 名女性）完成了精神疾病诊断筛查问卷、七天体力活动回顾和社交身体焦虑量表。方差分析比较了不同体力活动水平之间 SPA 和焦虑障碍症状的差异。逻辑回归分析了 PA 与模拟焦虑障碍状态之间的关系。中介分析估计了当 SPA 处于均值时，PA 变化对模拟焦虑障碍几率的影响。
AGAD、ASAD 和 APD 的患病率分别为 38.1%、60.0%和 15.1%。AGAD 和 ASAD 症状，但不是 APD 症状，在体力活动水平较高时明显较低。PA 与 AGAD、ASAD 和 APD 的几率较低相关；调整后这些发现没有统计学意义。SPA 的纯间接效应分别占 PA 对 AGAD 和 ASAD 的总效应的 58.2%和 47.9%；调整抑郁后，这些发现没有统计学意义。女性 AGAD、ASAD 和 APD 的几率更高；基于性别，中介发现没有差异。
横断面设计、自我报告的暴露和结果以及样本量是潜在的局限性。
年轻成年人中，体力活动水平较高者的 AGAD 和 ASAD 症状和几率较低；SPA 部分中介了这些关联，需要进一步的实验研究。
