RELATIONSHIP OF RESTING HEART RATE WITH BODY COMPOSITION AND OBESITY AMONG YOUNG ADULTS IN INDIA – A CROSS SECTIONAL STUDY Background: The autonomous dysfunction associated with obesity could lead to changes in Afreen Itagi1, Nagaraja S1, resting heart rate (RHR), which has been linked with adverse cardiovascular outcomes. Scanty Suresh Bondade1, Yunus GY2 data is available on RHR among young adults of non-obese (NW) and obese (OB). 1 Department of Physiology, JJM Aims & Objective: The present study was aimed at determining the effect of body composition Medical College, Davangere, and adiposity on RHR Karnataka, India Materials and Methods: Study was conducted on medical students (n= 132, age: 19-20 years) 2 Department of Public Health in Davangere, India. Anthropometric measures were obtained and BMI, WC, HC, WSR were Dentistry, Bapuji Dental College measured. Body fat percentage (BF %), Fat mass (FM) were estimated and Fat Free Mass and Hospital, Davangere, (FFM) was calculated. RHR was measured using a standard ECG after complete rest. Pearson’s Karnataka, India correlations (r) were computed obesity indices and RHR. ANOVA & Independent t test as appropriate were used to compare RHR between non-obese (NW) and obese (OB). Correspondence to: Afreen Itagi Results: The obesity indices showed 40.1% students were generally obese (BMI ≥ 25.0 (

Obese group presented with comparatively continuous faster Received Date: 29.10.2013 RHR (Mean 80.21 ± 3.8 bpm) and was significantly positively correlated with obesity indices Accepted Date: 08.11.2013 BMI, WC, WSR, FFM (r = 0.476, 0.678, 0.332, 0.617 respectively). Conclusion: RHR had higher values and significantly positive correlation with obesity indices DOI: among obese group compared to non-obese individuals (p
