Background: Evidences indicate altered circulating adipokine levels in obesity could increase the risk for cardiovascular disease (CVD). Hence, it is crucial to determine cardiovascular health by assessing heart rate variability (HRV) and its association with circulating adipokines.

Aim and Objectives: The aim of the study was to assess the adipokines level and its association with HRV in obese population.

Materials and Methods: A cross-sectional comparative study was conducted on 45 obese (body mass index [BMI] > 25–29.9 kg/m2) and 45 non-obese (BMI: 18.5–22.9 kg/m2) age-gender-matched participants. Lead-II electrocardiogram was recorded and HRV parameters were obtained. Biochemical parameters, that is, fasting blood glucose, fasting insulin, HOMA-IR, lipid profile, leptin, and adiponectin levels were estimated. Group comparisons were done by independent student’s t-test, whereas the association between the parameters was done by Pearson’s correlation using SPSS 20v. P < 0.05 was considered statistically significant.

Results: There was a significant increase in low frequency: high frequency (LF: HF) ratio (
