High blood pressure in a semi-urban community in south-south Nigeria: a community-based study

Afr Health Sci. 2013 Mar;13(1):56-61. doi: 10.4314/ahs.v13i1.8.

Abstract

Background: Non communicable diseases (NCDs) are taking their toll in most low and middle income countries; incidentally, in the same populations that are struggling to deal with communicable diseases, hence presenting a picture of "double tragedy". Most of the researches conducted on NCDs are facility-based; often in urban locations.

Objective: To determine the prevalence of high BP in a semi-urban community in Nigeria.

Methods: It was a cross-sectional study, where all the adult residents of the community were enrolled. Data was collected using a multi-section questionnaire, including anthropometric measurements. Data entry and analysis was done using SPSS 17.0 for windows and STATA 10.

Results: The results showed that 47.0% of the study population had a raised BP ≥140/90mmHg. At a univariate level, age, sex, higher income, more people in the household, daily cigarette smoking, daily alcohol intake and BMI, showed increased risk for high BP. However, sleeping for at least 8 hours a day showed protective influence against raised BP among the participants. In the adjusted model, only age, sex and BMI remained statistically significant with Odds Ratio (OR) of 1.04 (95%CI; 1.00, 1.08), 0.45 (95%CI; 0.22, 0.90) and 1.08(95%CI; 1.03, 1.13) respectively. The model had an area under curve of 71.9%.

Conclusion: It was concluded that there is a high prevalence of raised BP in this semi-urban community, thus the need for intervention and preventive services to curb the looming epidemic of hypertension in this community in particular, and Nigeria as a whole, cannot be overemphasized.
