RESUMO
May Measurement Month (MMM) is a global initiative that aims at raising awareness and screening people for high blood pressure (BP). Malawi has participated in MMM since 2017. A 2017 STEPwise Survey conducted in Malawi among 4187 participants found that 65.2% had never had their BP measured before, 26.8% had their BPs measured but not diagnosed, 3.9% were diagnosed but not within the last 12 months, and 4.1% were diagnosed within the last 12 months. An opportunistic cross-sectional survey of volunteers aged 18 and above was carried out in May and June 2019. All BP measurements, definition of hypertension and statistical analysis followed the standard MMM protocol. The screening took place in Nkhatabay, Lilongwe, and Blantyre. A total number of 9723 participants were screened with a mean age of 42.0 (SD 16.6) years. Of these 8444 (86.8%) had never had their BP measured within the last 12 months, 2559 (26.3%) had raised BP, 2169 (23.2%) of those with raised BP were not on treatment whereas 390 (4.0%) were on treatment. The results showed that many of the participants had not had their BP checked in the past year. There is a significant need to expand BP screening opportunities within Malawi for early detection of hypertension.
RESUMO
Raised blood pressure (BP) is a growing health care problem in the world leading to over 10 million deaths annually. May Measurement Month (MMM), which aims at raising awareness and screening people for raised BP, is assisting people to know their BP status. In 2018, an opportunistic cross-sectional survey was carried out during May and June in 10 791 volunteers aged 18 years and above following that done in 2017. The screening took place in Lilongwe, Blantyre, Dedza, Kasungu, and Nkhatabay districts mostly in hospitals/clinics, marketplaces, workplaces, and churches/mosques with Kasungu and Nkhatabay in rural areas. After multiple imputation, 2404 (22.3%) had hypertension. Of individuals not receiving antihypertensive treatment, 2101 (20.0%) were found to have raised BP. Only 303 (12.6%) of those with hypertension were receiving antihypertensive treatment, and of these 101 (33.3%) had uncontrolled BP. MMM was the largest BP screening campaign ever undertaken in Malawi. The results identified a large number of individuals with raised BP who were unaware and not on treatment and over one-third of those on treatment were uncontrolled, indicating the need for better management of cases. These results suggest that opportunistic screening can identify significant numbers with raised BP.
