Prevalence and biosocial determinants of hypertension in a rural population in Edo State, Southern Nigeria

Abstract

Background: Hypertension is a public health threat of global concern with increasing prevalence in many countries, including Nigeria.Aim: The aim of the study was to determine the prevalence and determinants of hypertension in a rural agrarian community in Edo North, Nigeria.Setting: The study was carried out in Ayua, a community in Edo North, southern Nigeria.Methods: This cross-sectional descriptive study involved the use of a structured interviewer-administered questionnaire to obtain relevant data. Body mass index (BMI), blood pressure and glucose were recorded. Data were analysed using Statistical Package for Social Sciences (SPSS) version 20.0.Results: Two hundred and nineteen participants aged 15 years completed the study with a mean age of 54.03 ± 16.61 years and females comprising 159 (72.6%) of the total. The prevalence of hypertension was 27.9% (in 61 participants). Twenty-one (9.8%) respondents gave a family history of hypertension. The mean BMI amongst respondents was 27.10 ± 6.61 kg/m2. Obesity and pre-obesity were found in 58 (26.5%) and 71(32.4%) respondents, respectively. The determinants of hypertension were age and BMI. Compared with those who were less than 40 years old, those aged 40–65 years and 65 years had 1.9 and 4.2 times increased odds of developing hypertension, respectively. Similarly, compared with the non-obese, obese participants had 2.3 times increased odd of having hypertension.Conclusion: Hypertension was highly prevalent in this rural community. Health sensitisation and intervention programmes are recommended in rural communities for early detection and management of hypertension, especially amongst older and obese adults.

Efeitos dos determinantes sociais da saúde na hipertensão: uma revisão sob a luz do modelo de Dahlgren e Whitehead

“…No que se refere a faixa etária, estudo realizado no Quênia com 43.898 indivíduos mostrou que a prevalência de HAS foi maior entre mulheres adultas casadas, com mais de 30 anos de idade, quando comparado aos homens. Destacando a maior prevalência da doença em idades mais avançadas (Mkuu et al, 2019;Parkash et al, 2019;Egbi et al, 2021).…”

“…In Asia, this disease kills 1.5 million people every year overall . [3] In 2013, the prevalence of hypertension in Indonesia nationally reached 25.8% of the Indonesian population. Currently the population of Indonesia has reached 252.124.458 people, which means there are 65.048.110 people suffering from hypertension.…”
