HAALSI Wave 1 Dried Blood Spot for C-Reactive Protein

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 Wave 1 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 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, as well as collection of dried blood spots (DBS). This dataset contains only the C-Reactive Protein (CRP) values assayed from the DBS during the HAALSI Wave 1 survey. The data may be merged to the HAALSI survey data using the unique identifier (prim_key).
