Abstract
Adiponectin is a fat derived protein. It is linked to obesity and its co-morbidities especially insulin resistance, type 2 diabetes, and certain components of metabolic syndrome.
Objective: The objective of this study was to correlate serum adiponectin levels with Insulin sensitivity, Lipid Profile and with BMI in self-reported healthy individuals. and to evaluate the relationship between serum adiponectin levels and key metabolic parameters including insulin resistance (HOMA-IR), lipid profile, and body mass index (BMI) in self-reported healthy individuals from the Pakistani population.
Methods: We designed a cross-sectional analytical study and recruited a cohort of eighty (80) self-reported healthy individuals in the study by non-probability convenient sampling. The whole experimental work was conducted at the Institute of Molecular Biology and Biotechnology (IMBB), The University of Lahore from September 2021 to June 2022. The adiponectin levels in patients’ serum were assessed by ELISA kit. Lipid profile was assessed by commercial Human Diagnostics® kits.
Results: Our results showed that mean value of serum adiponectin levels in subjects was 5.55±1.93 (Mean±SD) with no significant difference between male (5.43± 1.35) and female subjects (5.75 ± 2.59) at p>0.50. There was no significant correlation between adiponectin and any of the anthropometric or metabolic parameters including waist circumference, BMI, blood sugar fasting, serum insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and lipid profile at p>0.50 when checked by Spearman correlation testing. However, when multiple linear regression was used to check the association of adiponectin levels with waist circumference while controlling age and serum lipids, a statistically significant link was revealed (beta=0.34, p=0.03).
Conclusions: Our study adds to the developing pool of knowledge about the physiological role of adiponectin. There is no simple correlation of this adipokine with anthropometric and metabolic parameters. A positive association with waist circumference may be linked to the visceral intraabdominal fat which is a source of this adipokine. More studies are required to find out physiological role of adipokines on genetic and molecular grounds.
