目的:晚年抑郁症是一个重要的公共卫生问题,因为它具有毁灭性的后果。该研究旨在调查2008年参加全球老龄化和成人健康研究(SAGE第1波)的南非老年人的全国样本中自我报告的基于症状的抑郁症的患病率和相关因素。
方法:我们在2008年对南非3,840名年龄在50岁或以上的个体进行了一项基于人群的全国横断面研究。问卷包括社会人口学特征,健康变量,在过去的12个月中,人体测量和血压测量以及有关抑郁症状的问题。进行多元回归分析以评估社会人口统计学因素的关联,健康变量,和抑郁症。
结果:过去12个月中基于症状的抑郁症的总患病率为4.0%。在多变量分析中,功能性残疾,缺乏生活质量,和慢性疾病(心绞痛,哮喘,关节炎,和夜间睡眠问题)与过去12个月中自我报告的抑郁症状有关。
结论:南非老年人自我报告的抑郁症似乎是一个公共卫生问题,需要采取适当的干预措施来减少抑郁症的发生。确定与抑郁症相关的因素,包括功能性残疾,缺乏生活质量,和慢性疾病(心绞痛,哮喘,关节炎,和夜间睡眠问题),可以用来指导干预。确定的保护和风险因素可以帮助制定公共医疗保健政策,以改善老年人的生活质量。
OBJECTIVE: Late-life depression is an important public health problem because of its devastating consequences. The study aims to investigate the prevalence and associated factors of self-reported symptom-based depression in a national sample of older South Africans who participated in the Study of Global Ageing and Adult Health (SAGE wave 1) in 2008.
METHODS: We conducted a national population-based cross-sectional study with a probability sample of 3,840 individuals aged 50 years or above in South Africa in 2008. The questionnaire included socio-demographic characteristics, health variables, anthropometric and blood pressure measurements as well as questions on depression symptoms in the past 12 months. Multivariable regression analysis was performed to assess the association of socio-demographic factors, health variables, and depression.
RESULTS: The overall prevalence of symptom-based depression in the past 12 months was 4.0%. In multivariable analysis, functional disability, lack of quality of life, and chronic conditions (angina, asthma, arthritis, and nocturnal sleep problems) were associated with self-reported depression symptoms in the past 12 months.
CONCLUSIONS: Self-reported depression in older South Africans seems to be a public health problem calling for appropriate interventions to reduce occurrence. Factors identified to be associated with depression, including functional disability, lack of quality of life, and chronic conditions (angina, asthma, arthritis, and nocturnal sleep problems), can be used to guide interventions. The identified protective and risk factors can help in formulating public health care policies to improve quality of life among older adults.
