A Comparison of Leptin, Body Mass Index and Self-Efficacy Modification Levels after LEARN Program and Cognitive- Behavior Intervention among Obese and Subsequent Overweight Women

This research is conducted with the aim of making a comparison of effectiveness of LEARN program and cognitive- behavioral intervention (CBT) on modifying leptin and body mass index levels as well as subsequent eating and exercise self-efficacy among overweight and obese women. after announcement, 30 female volunteers with BMI more than 25 who were eligible for exclude- include criteria of experiment, were chosen and randomly assigned to two experimental groups including multidimensional LEARN and CBT intervention program, two groups of 15 member. After that, all the participants were replied (responded) to of eating and exercise self-efficacy items embedded in the questionnaires they received. Their BMI were calculated. Furthermore, to determine the Leptin levels, subjects’ blood samples were also measured and analyzed. Analysis of data was carried out using Analysis of Variance (ANOVA) which is a statistical method, with Frequent measuring revealed that both interventions culminate in a significant decrease in BMI and leptin levels and also an increase in eating and exercise self-efficacy (P<0.05); but, there were no significant differences, between two interventions, in these factors except Leptin (P>0.05). Besides, decrease in leptin levels were more significant in the LEARN group in comparison to those of CBT (P<0.05). Discussion and Both interventions by receiving positive feedback from health status and subsequent weight loss and improved physical function will lead to an enhancement in physical-bio-psychological components; But, LEARN program intervention due to its concentration on behavioral pathways could leads to more changes in biological components’ levels such as leptin.
