Key result

A nationally representative survey in Nigeria demonstrates a high hypertension prevalence of 44.9% among adults aged 40 and older, with significant ethnic variations.
High burden may guide Nigerian screening priorities; leaves open longitudinal confirmation of risk factors.
OBJECTIVE: Non-communicable diseases are now a global priority. We report on the prevalence of hypertension and its risk factors, including ethnicity, in a nationally representative sample of Nigerian adults recruited to a survey of visual impairment. METHODS: multi-stage, stratified, cluster random sample with probability proportional to size procedures was used to obtain a nationally representative sample of 13 591 subjects aged ≥ 40 years. Of these, 13 504 (99.4%) had a blood pressure measurement. RESULTS: The prevalence of hypertension was 44.9% [95% confidence interval (CI): 43.5-46.3% ]. Increasing age, gender, urban residence and body mass index were independent risk factors (p < 0.001). The Kanuri ethnic group had the highest prevalence of hypertension (77.5%, 95% CI: 71.0-84.0%). CONCLUSIONS: The high prevalence of hypertension in Nigeria is a cause for concern and suggests that it is inevitable that the impact of hypertension-related ill health is imminent, with the accompanying financial and societal costs to families and the state of Nigeria.

Murthy et al. (2013) conducted a cross-sectional in Hypertension (n=13,504). Sociodemographic and lifestyle risk factors (age, gender, urban residence, BMI, ethnicity) vs. Reference groups was evaluated on Prevalence of hypertension (95% CI 43.5-46.3). The overall prevalence of hypertension among Nigerian adults aged 40 years and older was 44.9%, with increasing age, female gender, urban residence, higher BMI, and Kanuri ethnicity identified as independent risk factors.
