Depressive symptoms are prevalent in older adults, and physical activity (PA) may have beneficial effects on depression. The purpose of this study was to explore the association between physical activity and depressive symptoms, taking into account demographic factors, and the associations between selected demographic factors and physical activity levels in community-dwelling older adults (age ≥ 60 years).
Data were drawn from the National Health and Nutrition Examination Survey 2005-2006. Descriptive statistics and logistic models were used in data analysis.
Four percent of participants reported moderate depressive symptoms, and 24% of subjects exhibited sedentary PA. Factors associated with increased risk of moderate depression included age, sedentary PA, and chronic medical conditions (ps < 0.05). Sedentary PA was significantly associated with age, race, education, BMI, smoking status, alcohol use, and taking psychotropics (ps < 0.05).
PA is a protective factor for depression in older adults, and clinical implications to encourage PA are discussed.
抑郁症状在老年人中普遍存在，体育活动（PA）可能对抑郁症有有益影响。本研究的目的是探讨体育活动与抑郁症状之间的关联，同时考虑人口统计学因素，以及社区居住的老年人（年龄≥60岁）中选定的人口统计学因素与体育活动水平之间的关联。
数据来自2005 - 2006年国家健康与营养检查调查。数据分析采用描述性统计和逻辑模型。
4%的参与者报告有中度抑郁症状，24%的受试者表现为久坐不动的体育活动。与中度抑郁症风险增加相关的因素包括年龄、久坐不动的体育活动和慢性疾病（P<0.05）。久坐不动的体育活动与年龄、种族、教育程度、体重指数、吸烟状况、饮酒情况和服用精神药物显著相关（P<0.05）。
体育活动是老年人抑郁症的保护因素，并讨论了鼓励体育活动的临床意义。
