Korelasi Antara Kadar Leptin dengan IMT, Lingkar Pinggang dan RLPP pada Orang Dewasa Obesitas Usia 19-25 Tahun di Universitas Warmadewa

Obesity causes negative impacts both psychologically as well as physically related to metabolic syndrome and cardiovascular diseases. Anthropometric measurements such as Body Mass Index (BMI), waist circumference, hip circumference, waist-hip circumference ratio (WHR) are used to identify obesity. Leptin originates from adipose tissue which can be used to identify obesity. Leptin works centrally as metabolic hormone through feedback negative mechanism to inhibit appetite and to increase calorie combustion along with increased body activity. This study aimed to confirm the correlation between leptin concentration and BMI, waist circumference, and WHR in adult obese individuals aged 19-25 years old at Warmadewa University. This study was an analytic correlation study carried out with a cross sectional data collection technique. Fifty two blood samples were collected from adult obese individuals at Warmadewa University, which were examined in Biomolecular Laboratory, Faculty of Medicine Warmadewa University. Fifty two adult obese individuals aged 19-25 years old, male and female, were measured for their height, weight, waist circumference, hip circumference and leptin concentration, by using sandwich ELISA method. Data were analyzed descriptively as well as statistically to assess the correlation. From this study, it was found that serum leptin concentration had a correlation with BMI (r=0.871 in females; p=0.001; r=0.549 in males), waist circumference (p=0.001; r=0.695 in females; p=0.003; r=0.490 in males); WHR (p=0.041; r=0.485 in females; p=0.019; r=0.401 in males). Confidence Interval (CI) 95%. Serum leptin concentration has significant positive correlation with BMI, waist circumference and WHR.
