Cardiovascular diseases (CVDs) are leading causes of deaths the world over. Half of such deaths are caused by coronary heart disease linked to development of atherosclerosis. Hypertension and obesity are leading risk factors for atherosclerotic CVDs, presence of which is predicted by microalbuminuria (MA). The study evaluated the prevalence of MA among secondary school students with risk factors for CVDs (obesity, overweight, pre-hypertension and hypertension) in Ilorin. The descriptive, cross-sectional study, carried out over a four month period (December 2017 to March 2018) involved 584 students (males, 45.0% and females, 55.0%) aged 10-18 years drawn from 14 schools in three Local Government Areas (LGAs) in Ilorin. Socio-demographic and other relevant information from the subjects were obtained using semi structured questionnaire after obtaining approval from the National Postgraduate Medical College of Nigeria. All the data collated from the questionnaire was entered into a statistical package for the social sciences (SPSS) version 21.0 spreadsheet and analyzed. The overall prevalence of MA was 30.1%. Late adolescent age group had significantly higher prevalence of MA (p = 0.005). Subjects with overweight and obesity were 6.7% and 7.5% respectively. The Mean BMI was significantly higher in females than males (20.0 ± 3.1 vs. 19.3 ± 3.3), (p = 0.011). Prevalence of pre-hypertension (pre-HTN) and hypertension (HTN) were 13.4% and 16.1% respectively. Microalbuminuria was more common in obese and hypertensive adolescents compared to their counterparts with normal weight and normal blood pressure (p<0.001 and 0.001 respectively).
