A total of 1,054 Hong Kong Chinese subjects aged 70 years or over were recruited into a cohort study to investigate the relation between social support and health outcomes. More than 30 social, health, and behavioral characteristics were recorded as baseline information when the study began in 1985. Mortality data were obtained during a 2-year follow-up. Logistic regression analyses were used to determine the roles of these variables in predicting mortality. The mortality patterns of Hong Kong and of the studied cohort closely resemble that of Western developed countries with cancer, heart disease, and cerebrovascular diseases as the leading causes of death. Besides sex and place of residence (whether living in the community or in homes for the elderly), the independent predictors of mortality included five baseline variables: being single or widowed, limited ability in activities of daily living, smoking habit, low body mass index, and poor self-evaluated health status. Subjects with at least three of these predictors had a relative risk of 3.9 (95% confidence interval 2.4-6.2) compared with those with zero to two of these characteristics.
共有1054名70岁及以上的香港华人受试者被纳入一项队列研究，以调查社会支持与健康结果之间的关系。1985年研究开始时，记录了30多项社会、健康和行为特征作为基线信息。在为期2年的随访期间获取了死亡率数据。采用逻辑回归分析来确定这些变量在预测死亡率方面的作用。香港及所研究队列的死亡率模式与西方发达国家极为相似，癌症、心脏病和脑血管疾病是主要死因。除了性别和居住地点（是否居住在社区或养老院）外，死亡率的独立预测因素包括五个基线变量：单身或丧偶、日常生活活动能力受限、吸烟习惯、低体重指数以及自我评估的健康状况不佳。与具有零至两个这些特征的受试者相比，至少具有其中三个预测因素的受试者的相对风险为3.9（95%置信区间2.4 - 6.2）。
