The underlying goal of the study was to examine gender-specific effects of leisure-time physical activity on the development of symptoms of anxiety.
The second wave of a prospective cohort survey (HUNT 2) was conducted during 1995-1997 in the county of Nord-Trøndelag, Norway, with a follow-up in 2006-2008 (HUNT 3). The sample consisted of 12,796 women and 11,195 men with an age range of 19-85 years. A binomial model with a log-link function and generalized linear model analysis with gamma distribution was used to assess the association between physical activity and anxiety symptoms (Hospital Anxiety and Depression Scale anxiety subscale, HADS-A).
A total of 1,211 (9.5 %) women and 650 (5.8 %) men developed HADS-defined anxiety (≥8 on the HADS-A scale). Men who scored in the middle tertile of the calculated physical activity index developed significantly fewer cases of HADS-defined anxiety compared with men in the lowest tertile (p < 0.05). In the gamma regression analysis for women, having higher scores on the moderate-high physical activity was associated with fewer symptoms of anxiety (p < 0.01).
Women developed almost twice as many cases of HADS-defined anxiety compared to men. Significant associations were found between general leisure-time physical activity and anxiety symptoms among women and men, but the true effect is likely to be different from the observed associations due to several threats to the internal validity in the study.
本研究的根本目标是检验休闲体育活动对焦虑症状发展的性别特异性影响。
1995年至1997年期间在挪威北特伦德拉格郡进行了前瞻性队列调查的第二轮（HUNT 2），并于2006年至2008年进行了随访（HUNT 3）。样本包括12,796名女性和11,195名男性，年龄范围为19至85岁。使用具有对数链接函数的二项式模型和伽马分布的广义线性模型分析来评估体育活动与焦虑症状（医院焦虑和抑郁量表焦虑子量表，HADS - A）之间的关联。
共有1,211名（9.5%）女性和650名（5.8%）男性出现了HADS定义的焦虑（HADS - A量表得分≥8）。在计算出的体育活动指数处于中间三分位数的男性中，与最低三分位数的男性相比，出现HADS定义的焦虑病例明显更少（p < 0.05）。在女性的伽马回归分析中，中度至高度体育活动得分较高与焦虑症状较少相关（p < 0.01）。
与男性相比，女性出现HADS定义的焦虑病例几乎是男性的两倍。在男性和女性中，发现一般休闲体育活动与焦虑症状之间存在显著关联，但由于研究内部效度存在多种威胁，真实效应可能与观察到的关联不同。
