The trend in blood pressure and hypertension prevalence in the general population of South Kivu between 2012 and 2016 : results from two representative cross-sectional surveys : the Bukavu observational study

Tijdschriftbijdrage - Tijdschriftartikel

Objective Data on blood pressure trends are scarce or unavailable in Sub-Saharan Africa in general and especially in the Democratic Republic of the Congo. This work addresses this gap by analyzing the dynamics in the prevalence and control of hypertension in a cohort of Congolese adults in South Kivu. Methods Two phases of data collection were conducted including a baseline at the beginning in 2012 and a follow up in 2016. The subjects were >= 18 years old living in urban (n = 4413) or rural areas (n = 6453). Hypertension was defined as a blood pressure >= 140/90 mmHg and/or taking antihypertensive medications. The crude prevalence of hypertension was ageadjusted to the WHO population. Results Between 2012 and 2016, there was a significant increase in blood pressure (+2.5/+1.4 mmHg; p = 0.001), age standardized prevalence of hypertension [19.0% vs. 18.0%; OR = 1.05 (1.02-1.08); p<0.0001], and obesity (7.9% to 9.8%; p< 0.0001) as well as the proportion of subjects > 60 years old (8.8% to 11.3%; p<0.0001) and those with tachycardia (10.5% to 14.4%; p<0.0001). The number of subjects under treatment of hypertension were statistically non-significant [16.1% vs. 14.3%; p = 0.29), but the level of control of hypertension was significantly reduced by 32.4% in 2016 compared in 2012 (43.5% vs. 64.4%; p = 0.0008). Conclusion There was an increase in the prevalence of hypertension as well as cardiovascular-associated risk factors in the population. However, this trend did not increase for treated subjects with no improvements in the level of AHT control. Therefore, improved strategies for the prevention and management of non-communicable diseases are very important in Sub-Saharan Africa.
