May Measurement Month 2018: an analysis of blood pressure screening results from Republic of the Congo

May Measurement Month 2021: an analysis of blood pressure screening results from Republic of the Congo, in the context of COVID-19 pandemic

To determine the proportion of hypertension among opportunistic screenees in the Republic of the Congo, and the relationships between, blood pressure (BP), alcohol intake, and history of coronavirus disease 2019 (COVID-19). Screening was carried out in July and August 2021 in Brazzaville, Pointe-Noire, and Pokola, after ethical clearance had been obtained. The campaign followed the guidelines outlined in the MMM21 protocol, collecting ideally three BP readings for each participant. The screening was carried out during the partial confinement of the population, due to the COVID-19 pandemic. Social distancing measures and protection against the transmission of COVID-19 were adhered to. A total of 2135 subjects were screened of which 1138 (53.3%) were male. The mean age was 29.9 ± 9.9 years (range: 18-69 years), and 2110 participants (98.8%) were of black ethnic origin. A previous COVID-19 positive test was reported in 217 (10.2%) and vaccination in 93 (4.4%). Diabetes was reported in 113 (5.3%), 16 (0.7%) were current smokers, 171 (8.0%) reported using alcohol intake at least once per month, and 539 (25.3%) reported meeting the WHO guidelines on physical activity. The proportion of participants with hypertension (≥140/90 mmHg or taking BP-lowering medication) was 34.1%, of whom 24.5% were aware, 11.9% were on medication, and only 4.0% were controlled (<140/90 mmHg). Rates of hypertension are high in the Republic of Congo, with low rates of awareness and treatment, and national authorities should address the contributing factors highlighted in this report to improve health care for the population.

Care Cascades for Hypertension in Low-Income Settings: A Systematic Review and Meta-Analysis

Objective: High blood pressure is the leading risk factor for cardiovascular disease. The hypertension care cascade (HCC) is increasingly being used to evaluate the effectiveness of interventions. This systematic review aims to examine HCC in low-income settings. Methods: The search strategy included articles published between January 2010 and April 2023. We excluded studies with incomplete HCC, on fragile patients or aged <18 years, reviews. We used the MOOSE guideline. Five researchers retrieved data on the survey year, country, population, HCC and diagnostic methods for hypertension. We used JBI Critical Appraisal Tools for quality assessment. Results: Ninety-five articles were analyzed. Average hypertension prevalence was 33% (95% CI: 31%-34%), lower in LICs than in LMICs (25% vs. 34%). The overall mean awareness of hypertension was 48% (95% CI: 45%-51%), its treatment was 35% (95% IC: 32%-38%) and its control 16% (95% CI: 14%-18%). In almost all steps, percentages were lower in LICs and in Sub-Saharan Africa. Conclusion: Trends in HCC vary between countries, with poorer performance in LICs. This review highlights the need for interventions tailored to low-income settings in order to improve hypertension care.

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

Hypertension is the strongest cardiovascular risk factor worldwide. May Measurement Month (MMM) is an international campaign for blood pressure (BP) screening initiated by the International Society of Hypertension. This work aims to estimate the proportion and the levels of awareness, treatment, and control of hypertension in participants of the MMM survey in Benin in 2018. A cross-sectional survey focused on people aged ≥18 years was conducted in May 2018 in nine rural and urban areas in Benin. A sampling of volunteers was done. BP was measured following the MMM protocol. Hypertension was defined as a systolic BP ≥140 mm Hg and/or a diastolic BP ≥90 mm Hg (mean of the second and third readings) and/or taking antihypertensive medication. Linear regression was used to identify BP associations. A total of 2035 people were screened, including 55.9% women. The mean age was 44.2 ± 15.9 years. The percentage with hypertension was 35.4%. Of 721 participants with hypertension, 56.2% were aware of their diagnosis, 39.7% were on antihypertensive medication, and 13.6% were controlled (<140/90 mmHg). The results confirm the significant proportion of hypertension in Benin. Education programs on risk factors, early detection, and better management strategies should be developed.

May Measurement Month 2019: an analysis of blood pressure screening results from Republic of the Congo

The aim of this study was to determine the proportion with hypertension among an opportunistic sample of the population of the Republic of the Congo. Screening was conducted during the period from 15 May to 15 June 2019. Participants included, consenting persons 18 years of age and over, from five cities: Brazzaville, Pointe-Noire, Oyo, Owando, and Ouesso. In total, 3157 participants were screened as part of the campaign. The mean age was 44.7 years (SD: ±14.9), and 47% were male. Based on the total participants, 881 (27.9%) were overweight and 447 (14.2%) were obese. A total of 583 (18.5%) participated in MMM 2017 or 2018 screenings. The proportion with hypertension was 33.5% (n = 1057), 42.6% of those were aware and 37.3% were taking antihypertensive medication. Of the participants on treatment, 62.4% were controlled (<140/90 mmHg). Overall, 23.3% of patients with hypertension were controlled. After imputation, the proportions with hypertension were 30.1% (n = 1475) according to standardized age and sex. Obesity (P < 0.001) and alcohol intake (P < 0.001) were associated with higher BP compared with normal weight and non-drinkers, respectively. With regards to the social disparities of the different regions of Congo, large scale screening is necessary, in order to report the real situation of hypertension. This will improve the overall management policy for this condition in our country.
