Assessing Hypertension Management in Peru's Peri-Urban Community in the Wake of the COVID-19 Pandemic.

Background: Hypertension is a global health challenge, particularly in low- and middle-income countries. Peri-urban areas such as Pampas de San Juan de Miraflores, Peru, face challenges that the COVID-19 pandemic exacerbated.

Objective: To assess the post-COVID-19 hypertension care cascade and mean systolic blood pressure (SBP) levels in Pampas de San Juan de Miraflores and to determine the proportion of individuals with hypertension who are diagnosed, treated, and have controlled blood pressure across age groups.

Methods: A cross-sectional survey (October 2022-January 2023) including adults aged >35 years from the 2010 CRONICAS study and a geographically based sample of households nearby. Data collection included a hypertension awareness questionnaire and standardized blood pressure measurements. Descriptive analyses characterized the age-specific hypertension care cascade and calculated mean blood pressure in four groups: healthy, unaware, aware and untreated, and aware and treated.

Results: Among 2,856 adults, age-specific hypertension prevalence based on self-reported medication use and current blood pressure screening was 13.3 % (35-44 years) to 54.6 % (>75 years). Awareness was 85 %; of those, 85 % were treated, and 76.8 % of them had controlled blood pressure. Mean SBP was highest in the unaware group (n = 102, 146.0 mmHg) and lowest in the healthy group (n = 1,929, 111.0 mmHg). These values were comparable among diagnosed patients, whether treated (n = 333, 126.0 mmHg) or untreated (n = 492, 128.0 mmHg).

Conclusions: Despite high awareness and relatively adequate control among untreated individuals, a substantial proportion remain undiagnosed or untreated after COVID-19. These findings underscore the need for interventions to improve early detection, treatment, and follow-up of hypertension.
