Cardiovascular risk factors and renal impairment among young adults in a tertiary institution in Southwest Nigeria

Background: Specific research is sparse on renal dysfunction among homogenous group of young adults. This study estimated the prevalence of renal dysfunction among apparently healthy young adults and determine association (if any) between renal dysfunction and some cardiovascular risk factors. Methodology:Undergraduates (18-37 years) of a tertiary institution were studied on 2017 World Kidney Day. Their biodata, blood pressure, anthropometry, total cholesterol and estimated glomerular filtration rate were determined. Data was analyzed using SPSS version 20.0. Results:A total of 640 students were studied (M:F=1:3.8). Their mean age was 23.1±2.8 years. Thirty-three(5.2%) participants had renal dysfunction (eGFR < 60ml/min/1.73m2). The mean age of subjects with renaldysfunction (eGFR < 60ml/min/1.73m2) was significantly higher with an inverse association to renal function (p = 0.005). Two hundred and fifty-seven(40.2%) and 58 (9.1%) participants were pre-hypertensive and hypertensive respectively; overweight, abdominal obesity and hypercholesterolaemia were found among 12.2%, 14.2% and 8.1% of subjects respectively. The mean body mass index (p = 0.009) and serum total cholesterol (p = 0.003) were significantly higher among females. There was a higher prevalence of renal dysfunction among females even though this was not to the significant level (5.9 v 2.2%, p = 0.12). Conclusions:The prevalence of renal dysfunction among young adults is lower than current global estimates. The prevalence of cardiovascular risk factors for CKD were lower than that of older adults with no significant association to renal dysfunction. Increasing age was found to be significantly associated with reduced renal function.

Study of association between sickle cell trait and renal dysfunction among young adults in South-west Nigeria.

BACKGROUND: Although sickle cell disease has become a recognized etiology of chronic kidney disease (CKD), the sickle cell trait (SCT) variant was until recently believed to be a benign carrier state with little or no effect on the health of affected individuals. However, recent studies now appear to suggest an association between SCT and CKD. OBJECTIVE: The objective of the study is to determine the association between SCT (hemoglobin AS) and renal dysfunction among young Nigerian adults. METHODOLOGY: This was a cross-sectional, descriptive study among apparently healthy undergraduates of Adeyemi College of Education, Ondo, southwest Nigeria. Their hemoglobin genotypes were determined using standard alkaline electrophoresis; their blood pressure, anthropometry, serum total cholesterol (TC), creatinine, and estimated glomerular filtration rate (eGFR) were determined. Data analyzed using Statistical Package for Social Sciences (SPSS) 20 were significant at P < 0.05. RESULTS: Six hundred and two subjects with HbAS (SCT, n = 465) and HbAA (non-SCT, n = 137) were studied. Their age range was 18-30 years with male-to-female ratio 1:3.8. There was no difference in the prevalence of renal dysfunction between SCT and non-SCT subjects (5.1% vs. 5.2%, P = 0.591). There was no increased risk of CKD among subjects with SCT (PR, 0.99 at 95% CI [0.417-2.348]). CONCLUSION: SCT was not associated with increased risk of renal dysfunction among young adults in Nigeria. Further studies are needed to clarify the controversy, especially in Nigeria, with a relatively higher prevalence of SCT.
