Prevalence, Awareness and Control of Hypertension in Greece before and after the COVID-19 Pandemic: May Measurement Month Survey 2019-2022

Background The COVID-19 pandemic had an adverse impact on several cardiovascular risk factors. This study investigated the prevalence, awareness and treatment of hypertension in Greece before and after the pandemic. Data were collected in the context of the May Measurement Month (MMM) global survey initiated by the International Society of Hypertension. Methods Adult volunteers (age ≥18 years) were recruited through opportunistic screening in public areas across cities in Greece in 2019 and 2022. Medical history and triplicate sitting blood pressure (BP) measurements were taken using validated automated upper-arm cuff devices. The data were uploaded to the international MMM cloud platform. Hypertension was defined as systolic BP ≥140 mmHg and/or diastolic ≥90 mmHg, and/or self-reported use of drugs for hypertension. The same threshold was used to define uncontrolled BP in treated individuals. Results Data from 12,080 adults were collected (5,727/6,353 in MMM 2019/2022; men 46/49%, p<0.01; mean age 52.7±16.6/54.8±16.2, p<0.001; smokers, 24.7/30.5, p<0.001; diabetics 12/11.5%, p=NS; cardiovascular disease 5/5.8%, p=NS). The prevalence of hypertension was 41.6/42.6% (MMM 2019/2022, p=NS), with 21.3/27.5% of hypertensives being unaware of their condition (p<0.001), 5.6/2.4% aware untreated (p<0.001), 24.8/22.1% treated uncontrolled (p<0.05), and 48.3/47.8% treated controlled (p=NS). Conclusions In Greece, the COVID-19 pandemic did not appear to affect the prevalence and control of hypertension, However, the rate of undiagnosed hypertension was higher after the pandemic. National strategies need to be implemented for the early detection and optimal management of hypertension in the general population in Greece.
