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.
RESUMO
Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programs worldwide. A World Health Organization and Ministry of Health STEPS Survey conducted in 2009 in Malawi found that 32.9% tested positive for age-standardized hypertension. The survey further showed that three-quarters (75%) of the participants never had their BP measured before and 94.9% with high BP were unaware of the hypertensive condition. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. BP measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. The screening took place in cities of Lilongwe and Blantyre mostly in hospitals, clinics, marketplaces, workplaces, and churches. About 4009 individuals were screened during MMM17. After multiple imputations, 849 (22.3%) had hypertension. Of individuals not receiving antihypertensive medication, 697 (19.1%) were found to have hypertension. Only 152 individuals were receiving antihypertensive medication, and of these 78 (51.4%) had uncontrolled BP. MMM17 was the largest BP screening campaign ever undertaken in Malawi. The results identified a large number with hypertension who were not on treatment and over half of those on antihypertensive treatment who were uncontrolled, indicating the need for better management of cases. These results suggest that opportunistic screening can identify significant numbers with raised BP.
