This study assessed factors associated with functional disability in old age in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. The theoretical model was based on predisposing (socio-demographic), extra-individual (social support, use of health services), and intra-individual factors (health conditions). The study was conducted in a probabilistic sample of 1,786 subjects aged > 60 years. The dependent variable was disability defined as mild (some difficulty) or severe (total dependence) in performing at least one basic activity of daily living. Prevalence of disability was 16% (8% mild; 8% severe). Age and worse self-rated health were independently and positively associated with mild and severe disability. Self-reported hypertension and arthritis were associated with mild disability, while diabetes and stroke were associated with severe disability. Severe disability was independently and negatively associated with number of visits by friends in the previous 30 days. According to the results, chronic conditions associated with disability in the study population are preventable, and severely disabled elderly had less extra-family social support.
本研究评估了巴西米纳斯吉拉斯州大贝洛奥里藏特地区老年人功能残疾的相关因素。理论模型基于易患因素（社会人口统计学因素）、个体外部因素（社会支持、医疗服务利用情况）和个体内部因素（健康状况）。该研究对1786名60岁以上的受试者进行了概率抽样。因变量为残疾，定义为在进行至少一项日常生活基本活动时有轻度（有些困难）或重度（完全依赖）残疾。残疾患病率为16%（轻度8%；重度8%）。年龄和自评健康状况较差与轻度和重度残疾独立且呈正相关。自我报告的高血压和关节炎与轻度残疾相关，而糖尿病和中风与重度残疾相关。重度残疾与过去30天内朋友来访次数独立且呈负相关。根据研究结果，该研究人群中与残疾相关的慢性病是可预防的，且重度残疾老年人获得的家庭外社会支持较少。
