In Sub-Saharan Africa(SSA) with effective antiretroviral treatment (ART)programmes, life expectancy has improved and more adults are now dying from non-communicable diseases (NCD) than HIV\/AIDS.  In 2004 around 1.2 million deaths were thought to be attributable to cardiovascular disease(CVD) alone in this region. The figure is expected to double by 2030.The population living with co-morbidities of HIV and NCD is growing, with detrimental social and economic impacts, creating an unsustainable burden on constrained health systems.\n\nIt is thought that stroke is particularly common in sub-Saharan Africa (SSA), possibly due to high prevalence of hypertension, but there is remarkably little accurate data. Determining and evaluating optimal strategies to reduce the burden of stroke in SSA requires validated tools to assess incidence, mortality and the contribution of modifiable risk factors. \n\n\nThis study involved community level stroke surveillance and gave the first estimate of incidence of transient ischemic attack(TIA) and fatal and non-fatal stroke in Malawi , and their determinants ,including HIV infection and ART. It was  aligned with the Malawi Ministry of Health priority areas during the time the study was conducted, and built on our existing collaboration with the Ministry of Health's NCD unit.\n\n\nNHSRC number: 1324","coll_dates":[{"start":"2014-12-01","end":"2017-07-31","cycle":"1"}],"nation":[{"name":"Malawi","abbreviation":"MWI"}],"analysis_unit":"Individual","universe":"The stroke surveillance was nested within the Karonga rural demographic surveillance population of 36,000(17,000 adults).","data_kind":"Sample survey data","notes":"- Stroke\/TIA clinical surveillance\n- Rapid assessment\/identification of stroke\/TIA\n- Risk factors for stroke\/TIA\n- Treatment for stroke\/TIA"},"method":{"data_collection":{"data_collectors":[{"name":"Malawi Epidemiology and Intervention Research Unit","abbr":"MEIRU","role":"","affiliation":""}],"coll_mode":["Face-to-face [f2f]"],"research_instrument":"Diagnostics and Medication STS  form , Stroke Register , Information Sheet  and  Consent For Cases and Controls, Diagnostic Imaging Form , Exit form,  Follow-up Form and STS FULL Questionnaire .","sources":[{"name":"","origin":"","characteristics":""}]}},"data_access":{"dataset_availability":{"original_archive":"Chilumba"},"dataset_use":{"contact":[{"name":"Malawi Epidemiology and Intervention Research Unit","affiliation":"","email":"","uri":""},{"name":"Karonga Prevention Study","affiliation":"","email":"","uri":""}],"conditions":"This data is made available for licensed access under the following conditions:\n\n1.
