HAALSI Wave 2 Survey

The Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) study is a population-based survey implemented by the Harvard Center for Population and Development Studies and the MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt) of the University of the Witwatersrand. HAALSI aims to examine and characterize a population of older men and women in rural South Africa with respect to health, physical and cognitive function, aging, and well-being, in harmonization with other Health and Retirement Studies. The second wave of data collection was conducted in October 2018-November 2019 among 4,176 members of the Wave 1 HAALSI cohort. The Wave 1 participants included 5,059 men and women aged 40 years or older, who were were randomly sampled from within the existing framework of the Agincourt health and socio-demographic surveillance system (AHDSS), in rural Mpumalanga province, South Africa. The survey was administered by local field workers in Shangaan at the participants' homes using computer-assisted personal interviewing (CAPI). Extensive survey data was collected on cognitive and physical functioning, social networks, cardiometabolic disease and risk factors, HIV and HIV risk, and economic well-being. The survey also included anthropometric measures and point-of-care blood tests for hemoglobin and glucose, as well as collection of dried bloodspots (DBS). An additional round of data collection is planned within the next two years. Future data releases will share results from DBS that were collected during the survey and tested for HIV, HIV viral load, HbA1c and CRP. (2020-07-16)

非洲健康与老龄化：南非INDEPTH社区纵向研究（Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa，以下简称HAALSI）是一项基于人群的调查研究，由哈佛大学人口与发展研究中心（Harvard Center for Population and Development Studies）以及金山大学（University of the Witwatersrand）的MRC/Wits农村公共卫生与健康转型研究组（阿金库尔）实施。HAALSI旨在与其他健康与退休研究（Health and Retirement Studies）保持协同一致，对南非农村地区的老年男性与女性人群的健康状况、躯体与认知功能、老龄化进程以及福祉水平进行考察与特征刻画。第二轮数据采集于2018年10月至2019年11月开展，覆盖HAALSI第一代队列的4176名成员。第一代队列的参与者共5059名40岁及以上的男性与女性，他们从南非姆普马兰加省农村地区的阿金库尔健康与社会人口监测系统（Agincourt health and socio-demographic surveillance system, AHDSS）现有框架中随机抽取获得。本次调查由当地外勤人员以尚加纳语（Shangaan）在参与者家中开展，采用计算机辅助个人访谈（computer-assisted personal interviewing, CAPI）方式进行。调查收集了涵盖认知与躯体功能、社会网络、心血管代谢疾病及其危险因素、艾滋病毒（HIV）及其感染风险、经济福祉等多方面的详尽数据。此外，本次调查还包含人体测量学指标检测、血红蛋白与葡萄糖的床旁血液检测，以及干血斑（dried bloodspots, DBS）样本采集。计划在未来两年内开展新一轮的数据采集工作。未来发布的数据将包含本次调查采集的干血斑样本的检测结果，检测项目包括HIV、HIV病毒载量、糖化血红蛋白（HbA1c）以及C反应蛋白（CRP）。（2020-07-16）
