TRIAL DESCRIPTION
Public title Effects of Training Community Health Workers and Their Interventions on Cardiovascular Disease Risk Factors among Adults in Morogoro, Tanzania
Official scientific title Effects of Training Community Health Workers and Their Interventions on Cardiovascular Disease Risk Factors among Adults in Morogoro, Tanzania
Brief summary describing the background and objectives of the trial Background: Cardiovascular diseases (CVDs) are increasingly contributing to morbidity and mortality in Tanzania. Public knowledge about cardiovascular disease risk factors (CVDRFs) is important for primary prevention of CVDs and can be improved through Community Health Workers (CHWs) interventions. Elsewhere, CVD prention interventions delivered by CHWs have shown to improve knowledge, self-management and behavior toward CVDRFs. However, evidence of improvement in knowledge and changes in CVDRFs following CHWs interventions is lacking in Tanzania. Broad objective: To assess effects of training CHWs and their CVD-specific interventions on knowledge and proportion of hypertension and other CVDRFs among adults in Morogoro, Tanzania. Specific objectives: 1. To assess changes in knowledge about hypertension and other CVDRFs following a training on CVD among CHWs in Kilombero and Ulanga districts in Morogoro region, Tanzania 2. To assess changes in knowledge about hypertension and other CVDRFs following CHWs home health education and healthy lifestyle promotion intervention among rural communities in Kilombero and Ulanga districts in Morogoro region, Tanzania 3. To assess changes in the proportion of hypertension and other CVDRFs following CHWs home health education and healthy lifestyle promotion intervention among rural communities in Kilombero and Ulanga districts in Morogoro region, Tanzania 4. To determine the outcome of the CHWs home health education and healthy lifestyle promotion intervention on 10-year risk for CVD event among rural communities in Kilombero and Ulanga districts in Morogoro region, Tanzania 5. To assess perceived quality and acceptability of the CHWs home health education and healthy lifestyle promotion intervention among rural communities in Kilombero and Ulanga districts in Morogoro region, Tanzania
