May Measurement Month 2018: an analysis of blood pressure screening results from Pakistan.

The May Measurement Month (MMM) screening campaigns comprise an opportunistic assessment of the arterial blood pressure (BP) of Pakistani adults (≥18 years old) and evaluate the level of awareness and spectrum of the problem of hypertension and the associated risk factors. The prospective study was carried out in May 2018 in multiple medical screening camps at hospitals, pharmacies, and public areas with the help of local health care workers under ethical guidelines. The volunteers took BP measurements using OMRON digital BP devices, in a seated position, and three successive readings were noted after 5 min rest. The mean values of the second and third readings were attained. Data were analysed centrally by the MMM project management team and multiple imputations were performed, where BP readings were missing. Hypertension was defined as a systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg, or in those taking antihypertensive medication. This study included 25 076 participants, of whom 14 726 (58.7%) were hypertensive. Among all hypertensives, only 11 681 were aware of their hypertension status. After imputation, age and gender standardization, mean systolic and diastolic BP were 129.8 mmHg and 82.9 mmHg, respectively. MMM17 data revealed that 55.2% of those screened were hypertensive in Pakistan, while in 2018 the proportion rose slightly to 58.7%. The prevalence of hypertension among those screened for MMM in Pakistan was high in both years. Although most patients with hypertension were treated, the majority remained uncontrolled. Further efforts to improve awareness and control are needed.
