HAALSI Baseline 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 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 baseline survey was conducted in November 2014-November 2015 among 5,059 men and women aged 40 years or older, who 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 baseline 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, glucose and lipids. Two additional rounds of data collection are planned over the next five years. Future data releases will share results from dried bloodspots (DBS) that were collected during the survey and tested for HIV, HIV viral load, HbA1c and CRP, as well as more extensive laboratory follow-up testing on a sub-sample of participants. The laboratory sub-study was administered in collaboration with the H3Africa/AWIGEN study (Genomic and Environmental Risk Factors for Cardiometabolic Disease in Africans), which will examine genetic data from these participants.

非洲健康与老龄化研究：南非INDEPTH社区纵向队列研究（Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa，以下简称HAALSI）为基于人群的调查项目，由哈佛大学人口与发展研究中心（Harvard Center for Population and Development Studies）与金山大学MRC/Wits农村公共卫生与健康转型研究组（MRC/Wits Rural Public Health and Health Transitions Research Unit of the University of the Witwatersrand）联合实施。HAALSI旨在与其他健康与退休研究体系保持协调一致，对南非农村地区中老年男女群体的健康状况、躯体与认知功能、衰老进程以及福祉水平进行考察与特征刻画。本研究基线调查于2014年11月至2015年11月间开展，研究对象为从南非普马兰加省农村地区阿金库尔健康与社会人口学监测系统（Agincourt health and socio-demographic surveillance system，以下简称AHDSS）现有框架中随机抽取的5059名40岁及以上男女居民。基线调查由当地外勤人员以尚加纳语（Shangaan）在受访者家中通过计算机辅助个人访谈（Computer-Assisted Personal Interviewing，以下简称CAPI）完成。本次调查收集了覆盖认知与躯体功能、社会关系网络、心血管代谢疾病及其危险因素、人类免疫缺陷病毒（HIV）感染状况与感染风险、经济福祉等领域的全面调研数据。调查同时包含人体测量学指标采集以及针对血红蛋白、葡萄糖与脂质的床旁血液检测项目。未来五年内，研究团队还计划开展两轮额外的数据采集工作。后续数据发布将包含本次调查采集的干血斑（Dried Blood Spots，以下简称DBS）样本的检测结果，其中涵盖HIV感染状况、HIV病毒载量、糖化血红蛋白（HbA1c）与C反应蛋白（CRP）的检测结果；同时还将公布针对部分受访者亚样本开展的更全面的实验室追踪检测数据。本实验室子研究与H3Africa/AWIGEN研究（Genomic and Environmental Risk Factors for Cardiometabolic Disease in Africans，即非洲人群心血管代谢疾病基因组与环境危险因素研究）联合开展，该研究将对本次受访人群的遗传数据进行分析。
