Evaluation of peroxisome proliferator-activated receptor-gamma (Ppar-γ) and metabolic dysfunction among hypertensive nigerians

•This study demonstrated a non-significant elevated increase in serum level of peroxisome proliferator-activated receptor-gamma (PPAR-γ) among hypertensive group.•Peroxisome proliferator-activated receptor-gamma (PPAR-γ) exhibited a significant negative association with glycated haemoglobin (HBAIC); thus may be used as a predictor for future events of type 2 diabetes mellitus among non-diabetic hypertensive Nigerians.•Hypertensive volunteers manifested a significant increase in HOMA-IR-a demonstration of occult insulin resistance which may precipitates future incidence of type 2 diabetes mellitus.•A positive association existed between Cholesterol and HOMA-IR among Hypertensive Nigerians. Hypertension is gradually becoming a major health burden in Nigeria; the most populous African nation. Often this starts unnoticed, but later, this disorder leads to complications and death if not properly managed. This study assessed the level of peroxisome proliferator-activated receptor-gamma (PPAR-γ), insulin, glucose and lipid profile components in hypertensive Nigerians. A total number of four hundred and nineteen volunteers consisting of two hundred and fifteen (215) hypertensive and two hundred and four (204) normotensive participants (of which two hundred and sixty (260) and one hundred and fifty-nine (159) were female and male respectively) participated in this study. Blood pressure of all volunteers was measured and blood samples of the consenting participants were collected in their fasting state and were analyzed for PPAR-γ, insulin, glucose, glycated haemoglobin (HbA1c) and lipid profile using enzyme-linked immunosorbent assay and Cobas C-111 auto-analyzer respectively. Homeostatic model assessment for insulin resistance (HOMA-IR) was calculated. The mean body mass index (BMI) and blood pressure of hypertensive volunteers were higher (P
