Key result
Opportunistic screening reveals ~34% hypertension prevalence in the Republic of the Congo.
Why the study?
Large scale screening is necessary to report the real situation of hypertension and improve management policy in the Republic of the Congo due to social disparities across regions.

What is the prevalence, awareness, treatment, and control of hypertension in an opportunistic sample in the Republic of the Congo?
Opportunistic screening in the Republic of the Congo revealed a high prevalence of hypertension (33.5%) with low rates of awareness, treatment, and control, highlighting the need for large-scale screening and improved management policies.
Opportunistic screening yields initial hypertension estimates in Congo; leaves open the need for population-based studies before guiding practice.
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.

Mbolla et al. (2021) conducted a cross-sectional in Hypertension (n=3,157). Blood pressure screening was evaluated on Proportion with hypertension. Opportunistic blood pressure screening of 3,157 adults in the Republic of the Congo revealed a 33.5% prevalence of hypertension, with only 23.3% of hypertensive patients achieving BP control.
