Trend in the prevalence, awareness, treatment and control of hypertension among adult over in Nigeria over a 4-year period

Background Hypertension is the commonest risk factor for most cardiovascular and cerebrovascular diseases, also the commonest cause of sudden unexpected death in the country. Despite concerted efforts to reduce the burden of this condition through increasing awareness, treatment and control rate of hypertension among adults in Nigeria. The rates of hypertension awareness (60%), treatment (34%), and control (12%) have been reported recently These figures need to change for the improved health of the citizens. Objective The study assessed the trend in the prevalence, levels of awareness, treatment, and control of hypertension among adults in urban setting in Nigeria, Sub-Sahara Africa. Methods This was a retrospective study. Data collected from opportunistic screening of adults aged 15 years and above in 4 urban communities during May Measurement Month from 2020 to 2023 was analyzed. Standardized protocol was used to collected data on socio-demographics and anthropometric measurements, blood pressure and pulse rate were measured using digital blood pressure monitors after patient have rested for at least 15 minutes. Hypertension was defined based on the 7th Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of Hypertension. Data was analyzed using SPSS 22 and p-value <0.05 was statistically significant Results We analyzed data of 2676participants. The mean age was 40.4years (SD 15·04), 68·5% of whom were women, 2.8% had diabetes mellitus, and 50·9% were overweight/obese. A third of the participants (33·9%) had hypertension, more than half of whom (57·2%) were aware that they were diagnosed of hypertension. The prevalence reduced from 39.7% in 2020 to 26.8% in 2023. Among those diagnosed, 66.5% were taking medication, and among those taking medication 32.5% had controlled blood pressure. We noted an increasing improvement in the rate of awareness from 35.4% to 72.5%, treatment from 46.7% to 82.6% and control from 5.7% to 52.3% over the 4-year period, p-value 0.000 (figure 1). When comparing between the hypertensives and non-hypertensives; higher age group (55years and above), the presence of diabetic mellitus and overweight/obesity showed statistically significant association, all at p-value of 0.000 each (table 1). Conclusion Hypertension is still a major problem among urban dwellers in Akwa Ibom State, with almost every one out of three adults have the condition. Though there is a decreasing trend in the prevalence and increasing trend in the awareness, treatment and control of hypertension, these rates are still suboptimal. Urgent measures are needed to reduce the prevalence and improve hypertension control among this population.
