Statement of problem

Comorbid anxiety and depression is increasingly prevalent in adolescents, and comorbidity results in greater symptom severity and duration. Our previous reports support positive benefits of physical activity (PA) for depressive symptoms among adolescents (see Mcdowell, MacDonncha, & Herring, 2017). However, the impact of comorbid anxiety on PA, depressive symptoms, and their associations is unknown. It is plausible that comorbid anxiety may be an important consideration when examining associations between PA and depressive symptoms. Thus, we critically expand our previous report by investigating differences in depressive symptoms across PA status based on comorbid anxiety and depression status.

Methods

Adolescents (N = 481; 200 female) aged 15.1 ± 1.7 y self-reported PA status; low, moderate, and high PA were classified based on ≥60 min s of PA 0–2, 3–4, and ≥5 d/wk, respectively. The Quick Inventory of Depressive Symptomatology assessed depressive symptoms (≥6 classified as depressed). The Trait subscale of the State-Trait Anxiety Inventory assessed anxiety symptoms (≥50 classified as anxious). Two-way ANCOVA was followed by Bonferroni-adjusted simple effects analyses.

Results

The interaction between PA and comorbid status was statistically significant (p < 0.001). Depressive symptoms were significantly higher for comorbid anxiety with low (p ≤ 0.007) and high PA (p ≤ 0.003) compared to moderate PA, significantly higher for comorbid anxiety compared to depression-only for low (p < 0.001) and high PA (p < 0.001), and non-significantly higher for moderate PA (p > 0.30).

Conclusion

Depressive symptoms differed across PA levels based on comorbid anxiety status.

抑郁症状因青少年的共病焦虑和抑郁状态而异，其身体活动状态也不同

问题陈述

合并症焦虑症和抑郁症在青少年中越来越普遍，合并症导致症状严重程度和持续时间延长。我们以前的报告支持体育锻炼（PA）对青少年抑郁症状的积极益处（参见Mcdowell，MacDonncha，＆Herring，2017）。但是，并存焦虑症对PA，抑郁症状及其相关性的影响尚不清楚。在检查PA和抑郁症状之间的关联时，合并焦虑症可能是重要的考虑因素。因此，我们通过调查基于共病焦虑和抑郁状态的整个PA状态下抑郁症状的差异，来扩展我们以前的报告。

方法

青少年（N = 481； 200名女性），年龄为15.1±1.7岁，自我报告的PA状态；低，中和高PA分别根据PA 0–2、3–4和≥5d / wk的≥60 min s进行分类。抑郁症状快速调查表评估了抑郁症状（≥6被归类为抑郁）。状态-特质焦虑量表的特质子量表评估了焦虑症状（≥50分类为焦虑）。双向ANCOVA之后，进行Bonferroni调整的简单效果分析。

结果

PA与合并症状态之间的相互作用具有统计学意义（p  <0.001）。抑郁症状为共病焦虑显著高于低（p  ≤0.007）和高PA（p 相比抑郁仅对低（相对于中度PA，显著更高为共病焦虑≤0.003）p  <0.001）和高PA（p  <0.001），而中度PA则无明显升高（p  > 0.30）。

结论

根据合并症的焦虑状态，抑郁症症状在不同的PA水平上有所不同。
