Hubungan Indeks Massa Tubuh, Lingkar Pinggang, Dan Lemak Tubuh dengan Stress Oksidatif Remaja Obesitas

Abstract

Teenagers are one of the age groups that are prone to obesity. Obesity experienced by adolescents is a nutritional problem that is increasing rapidly and has become a major public health problem. Obesity occurs due to an imbalance in energy intake over a long period of time, resulting in excessive fat accumulation, which results in weight gain. The purpose of this study was to identify the relationship between body mass index (BMI), waist circumference, and percent body fat with markers of oxidative stress in obese adolescents. The research method is an experimental research. The subjects of the study were 24 adolescents aged 13-15 years. Data were collected using a questionnaire and analysis of malonaldialdehyde (MDA) and superoxide dismutase (SOD) levels in the subject's blood serum. In addition, data in the form of BMI, percent body fat, waist circumference, pattern and level of food consumption. Data analysis was carried out descriptively and inferentially at the significance level  to find out the differences in treatment using the t-test if the data were normally distributed and the Mann-Whitney test if the data were not normally distributed. Next, to find out the closeness of the relationship using the Pearson correlation test The results showed that there was a moderately significant negative correlation between percent body fat and serum MDA, but body mass index, waist circumference, was not significant. The higher the percentage of body fat, the lower the serum MDl. There is no significant relationship between BMI, LP, and % LT with serum SOD.
