广场舞对呼吸道病毒感染后抑郁及睡眠障碍中老年女性身心健康的影响OA

Objective:To examine the multidimensional effects of square dance exercise interventions on the physical and mental health of middle-aged and elderly women experiencing depression and insomnia following respiratory viral infections.Methods:A total of 78 middle-aged and elderly women with stable conditions for more than or equal to 1 month after acute respiratory viral in-fection admitted to community health service centers in Xinwu District sub-districts and Huishan District sub-districts of Wuxi Cit-y from November 2023 to December 2024 were selected as the research subjects,and they were randomly assigned to a control group(40 participants,12 weeks of sleep health education)and an observation group(38 participants,12 weeks of square dance exercise five times weekly in addition to health education).The Patient Health Questionnaire-9(PHQ-9)and the Insomnia Severi-ty Index(ISI)were used before and after the intervention to assess psychological and sleep quality.Additionally,body weight,body mass index(BMI),vital capacity,and grip strength were measured to evaluate physical health.Metabolic indicators such as serum triglycerides(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),and fasting glucose(Glu)were measured to comprehensively evaluate the effectiveness of the intervention.Results:In the intra-group comparisons,no significant changes were observed in any of the indicators in the control group after the interven-tion(P＞0.05).In the observation group,PHQ-9 and ISI scores,body weight,BMI,and levels of TC,LDL-C,and Glu decreased significantly,while vital capacity,grip strength,and HDL-C levels increased significantly(P＜0.05).In the inter-group compari-son,the improvement effects of all indicators in the observation group were significantly greater than those in the control group(P＜0.05).Conclusion:A 12-week square dance intervention can effectively alleviate symptoms of depression and insomnia in this population,while simultaneously improving physical fitness and metabolic health,thereby enhancing overall physical and men-tal well-being.This approach is feasible and practical,and holds significant potential for community-wide implementation.
