Description:Malawi Population-based HIV Impact Assessment (MPHIA) 2015-2016 was a nationally representative, cross-sectional, population-based survey of households across Malawi. It focused on measuring key biological endpoints to provide direct estimates of HIV infection risk and burden, and on the effectiveness and population-level impact of the HIV-related prevention, care, and treatment interventions implemented in the country. Its primary objectives were to estimate the national-level annual HIV incidence among adults ages 15-64 years, and the subnational prevalence of HIV VLS among HIV-positive adults. In addition, MPHIA measured national and subnational adult HIV prevalence, CD4 counts, ARVs in blood, transmitted HIV drug resistance, pediatric HIV prevalence, and progress toward the UNAIDS 90-90-90 targets defined by UNAIDS. The MPHIA is the first national survey to conduct these measurements in Malawi. The survey also collected information on behaviors associated with HIV acquisition and transmission, common HIV co-morbidities, and other health conditions.
The survey used a two-stage, stratified cluster sample design, in which census EA (clusters) were selected in the first stage and households in the second stage. The sample was stratified by seven geographical zones: North, Central-East, Central-West, Lilongwe City, South-East, South-West, and Blantyre City. Data collection was conducted between the end of November 2015 and August 2016. The survey interviewed 11,386 households. In the households surveyed, 22,405 adults ages 15-64 years and 9,993 children ages 0-14 years were eligible to participate in the survey. Altogether, 88% (19,652) of eligible adults were interviewed, and 87% (17,187) of interviewed adults and 62% (6,166) of eligible children provided blood for biomarkers assessment to determine HIV status. The MPHIA provided home-based HIV testing and counseling (HBTC) with return of results, and point of care (POC) CD4 count for those who were HIV positive. HIV VL results and early infant diagnosis (EID) results were returned to participants through health facilities of their choice. The MPHIA provides weighted estimates. Analysis weights account for sample selection probabilities and are adjusted for nonresponse and noncoverage.
