The present study examined the relationships among physical activity (PA), symptom reporting, self-esteem, and satisfaction with life (SWL) in 133 women (M age=51.12, S.D.=4.10) of varying menopausal status.
Multivariate analyses of co-variance (MANCOVA) revealed that independent of menopausal status, women who were more physically active reported significantly less severe vaso-somatic and general somatic symptoms, and higher levels of physical self-worth (PSW). Subsequent hierarchical regression analyses indicated that expended MET-h/week, reported symptoms (frequency and severity, respectively), and PSW accounted for significant variance in SWL (R2 model=0.32, for symptom frequency, and 0.33, for symptom severity). Physical activity was significantly related to SWL through the mediation of PSW. However, both reported symptom frequency and severity retained significant association with SWL after controlling for PSW, although the original associations were significantly reduced. Finally, both symptoms and MET-h/week were independent contributors to the variance in PSW (R2 model=0.33 and 0.34).
The results suggest that being physically active may reduce perceived severity of menopausal symptoms and enhance psychological well-being, and that the relationship between physical activity and QOL in mid-life women may be mediated by factors such as physical self-perceptions and menopausal symptoms.
本研究调查了133名处于不同绝经状态的女性(年龄均值 = 51.12,标准差 = 4.10)的身体活动(PA)、症状报告、自尊和生活满意度(SWL)之间的关系。
多变量协方差分析(MANCOVA)显示,无论绝经状态如何,身体活动较多的女性报告的血管躯体症状和一般躯体症状明显较轻,身体自我价值感(PSW)水平较高。随后的分层回归分析表明,每周消耗的代谢当量小时数、报告的症状(分别为频率和严重程度)以及PSW在SWL中解释了显著的方差变异(症状频率的R2模型 = 0.32,症状严重程度的R2模型 = 0.33)。身体活动通过PSW的中介作用与SWL显著相关。然而,在控制PSW后,报告的症状频率和严重程度与SWL仍保持显著关联,尽管最初的关联显著降低。最后,症状和每周代谢当量小时数都是PSW方差变异的独立贡献因素(R2模型分别为0.33和0.34)。
结果表明,进行身体活动可能会降低更年期症状的感知严重程度并增强心理健康,并且身体活动与中年女性生活质量之间的关系可能由身体自我认知和更年期症状等因素介导。
