抑郁症状对老年人的食欲下降有很大影响。社交活动与抑郁症状减轻之间也存在关联，但食欲和社交活动与抑郁症状之间的机制尚不清楚。这项横断面研究探讨了社交活动通过抑郁症状对食欲的直接和间接影响。共有 259 名社区居住的老年人（平均年龄 75.1 +/- 5.3 岁；55% 为女性）完成了营养食欲问卷委员会 (CNAQ) 和包含 15 项的老年抑郁量表 (GDS)。我们使用 GDS-15 的截止分数 6 来确定参与者是否表现出抑郁症状。社交活动根据每月至少参加1-3次的活动次数进行评估。社会活动的类型包括当地社区、爱好、体育、公民、工业、宗教、志愿者等。其他评估因素包括年龄、性别、教育程度、财务状况、生活状况和合并症。为了检查社交活动、抑郁症状和食欲之间的关系，使用结构方程模型（SEM），在多变量分析中调整与抑郁症状或食欲相关的变量。 SEM 显示，参与更多类型的社交活动通过减少抑郁症状对更高的食欲得分产生显着的间接影响（β = 0.04，p = 0.018）。我们的研究结果表明，老年人积极参与社交活动可能不会出现抑郁症状，从而对良好的食欲产生积极影响。需要进一步的纵向或干预研究来证实我们的发现。
Depressive symptoms have a strong effect on appetite decline in older adults. There is also an association between social activity and decreased depressive symptoms, but the mechanism between appetite and social activity with respect to depressive symptoms is unclear. This cross-sectional study examined the direct and indirect effects of social activity on appetite, via depressive symptoms. A total of 259 community-dwelling older adults (mean age 75.1 +/- 5.3 years; 55% female) completed the Council on Nutrition Appetite Questionnaire (CNAQ) and the 15-item version of the Geriatric Depression Scale (GDS). We used a cutoff score of 6 on the GDS-15 to determine whether participants displayed depressive symptoms. Social activity was assessed based on the number of activities participated in at least 1-3 times per month. The types of social activity consisted of local community, hobby, sports, citizen, industry, religion, volunteer, and others. Other assessed factors included age, sex, education, financial status, living situation, and comorbidities. To examine the relationships among social activity, depressive symptoms, and appetite, structural equation modeling (SEM) was used, adjusting for variables associated with depressive symptoms or appetite in multivariate analyses. SEM revealed that participation in more types of social activity had a significant indirect effect on higher appetite score via less having depressive symptoms (beta = 0.04, p = 0.018). Our findings suggest that active participation in social activities may have a positive effect on good appetite via not having depressive symptoms among older adults. Further longitudinal or intervention studies are needed to confirm our findings.
