A Comparison between LEARN Program and Cognitive- Behavior Intervention on Modifying Leptin Levels, Body Mass Index, Eating, Exercise and Self- Efficacy among Obese and Overweight Women

Genetic, environmental, physiologic, psychological, and sociocultural variables are contributing factors to the development of obesity. Obesity and overweight are risk factors for cardiovascular diseases, type II of diabetes, and hypertension. Hence, the aim of this was to compare the effectiveness of LEARN program and cognitive- behavior therapy (CBT) on modifying leptin levels, body mass index, eating, exercise and self- efficacy among overweight and obese females. Method: 30 volunteer females with BMI>25 were selected and randomly assigned into two experimental groups (i.e. LEARN multidimensional program and CBT). Data analysis were conducted by using variance analysis with repeated measures. Results: Data analysis by variance analysis with repeated measures revealed that both interventions could significantly modify BMI, eating and exercise self- efficacy, and leptin levels (P<0.05). But, there were no significant differences between two interventions except to leptin levels (P>0.05). So that, leptin levels were more decreased among LEARN group in comparison to CBT group (P<0.05). Conclusion: It seems that both interventions by receiving positive feedback from health status in consequence to weight reduction and modifying physical function could lead to enhancing physicalbio- psychological components. But, LEARN program by focusing on behavioral pathways could more modify biological components levels e.g. leptin
