Cardiovascular Risk Factors in the 21st Century in a Semi-Urban Slum in North-Central Nigeria

Cardiovascular disease is prevalent in most low- and middle-income countries, and it is a major cause of disability and low quality of life. Stroke incidence is rising in tandem with the prevalence of its risk factors. Our research aims to identify stroke risk factors in a semi-urban slum in northcentral Nigeria.

This community-based, cross-sectional study was conducted in July 2017 to determine the prevalence of stroke risk factors among adult (≥18 years) residents of the Kabong community, in Jos, north central Nigeria. A total of 196 participants were recruited by multistage sampling technique. An adapted WHO STEPS questionnaire was used for the study and blood samples were obtained for lipid biochemistry.

We studied 196 participants, of whom 118 (60.2%) were females. The participants' median age was 48 (29) years, with those ≥ 65 years accounting for 17.3%. Generalized and abdominal obesity, hypertension, and diabetes mellitus were all prevalent in 39.1%, 52.3%, 37.1% and 17.8% of the population respectively. A LDL/HDL cholesterol ratio of >2.5 was observed in 74.1% of participants, elevated total cholesterol in 52.3%, elevated LDL-cholesterol in 57.4%, low HDL-cholesterol in 68.5% and high triglycerides in 13.2%. Current smoking and alcohol consumption were found in 4.1% and 32% of respondents, respectively.

There is a high prevalence of cardiovascular risk factors in this young population. Elevated blood pressure, hypertriglyceridemia, and illiteracy were all predictors of cardiovascular events. Health education, screening, and lifestyle changes are needed to reduce future cardiovascular disease burden.
