May Measurement Month 2017-19: an analysis of blood pressure screening results from Niger.

The aim of this study was to screen for cardiovascular risk factors with particular focus on high blood pressure (BP) in Niger and thereby to raise awareness among the population of Niger about raised BP and the associated risk to health. The city of Niamey served as our study location during the month of May in 2017, 2018, and 2019. We screened volunteer adults aged ≥18 years, who completed a pre-established questionnaire and had three sitting BP measurements taken. Hypertension was defined as a systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg (based on the mean of the second and third BP readings) or being on antihypertensive medication. We screened 2297 adults of which 42.9% were women and 57.1% men. Of the 2297 screened, 33.2% were found to be hypertensive of whom only 26 (3.4%) were recorded as being on treatment. Approximately 30% of those screened were found to be obese or overweight. High BP is a real public health danger, and this study finds alarming figures that highlight the need for improved policies for screening and management of hypertension. Raising awareness and improving detection of hypertension remain essential to reduce the burden of cardiovascular disease.
