我们使用最近收集的来自非洲健康与老龄化的数据：来自南非Agincourt的南非INDEPTH社区（HAALSI）队列的纵向研究，以描述该老年人群的身体功能，并将身体健康的总体水平和年龄轨迹置于低收入和中等收入国家（LMICs）的其他健康与退休研究（HRS）姐妹研究的背景下我们进行了多元回归，以估计从自我报告评估的身体功能的关联。（日常生活活动[ADL]受限，自我报告的健康状况）和性能（握力，步态速度）与HAALSI的社会人口统计学和健康特征，并使用完全相互作用的回归模型来比较身体功能结果的年龄模式。报告的健康状况最低，男性在控制社会人口统计学和健康特征的情况下，ADL受限的几率高出30%。测量的身体表现与社会经济条件密切相关，但自我报告的措施具有更小或更弱的社会经济梯度。在国际年龄调整比较中，HAALSI样本的体能结果低于大多数比较人群。作为第一个在非洲进行的HRS姐妹研究，HAALSI增加了该地区人口老龄化和健康的重要信息。持续不断的HAALSI数据将成为了解LMIC背景下残疾复杂过程差异的关键资源。
We use recently-collected data from the Health and Aging in Africa: a Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) cohort from Agincourt, South Africa, to describe physical functioning in this aging population, and place the overall level and age-trajectories of physical health in the context of other Health and Retirement Study (HRS) sister studies in low- and middle-income countries (LMICs).We conduct multiple regression to estimate associations of physical functioning assessed from both self-report (activities of daily living [ADL] limitation, self-reported health) and performance (grip strength, gait speed) with socio-demographic and health characteristics in HAALSI, and use fully-interacted regression models to compare age-patterns of physical functioning outcomes cross-nationally.Gender differences in self-reported health are minimal, and men had 30% higher odds of being ADL limited controlling for socio-demographic and health characteristics. Measured physical performance is closely tied with socioeconomic conditions, but self-reported measures have a much smaller or weaker socioeconomic gradient. In international age-adjusted comparisons, the HAALSI sample had lower physical performance outcomes than most comparison populations.As the first HRS sister study undertaken in Africa, HAALSI adds vital information on population aging and health in the region. Continuing waves of HAALSI data will be a key resource for understanding differences in the complex processes of disability across LMIC contexts.
