ABSTRACT
Introduction: There is rising concern about the increasing prevalence of adolescent obesity in recent decades and despite many studies conducted to elucidate the biological factors of obesity, there is limited data on the psychological factors of obesity. The aim of this study was to investigate the role of body image dissatisfaction and mental health in prediction of obesity
Materials and Methods: This study has a fundamental purpose and the method of data collection is correlational. In this study, 60 students [30 obese and 30 with normal weight] were selected by purposive sampling among the students of schools in Boukan city and the body image questionnaire and general health questionnaire [GHQ] were used to obtain relevant data. Data were analyzed by logistic regression
Results: Results showed that mental health and body image dissatisfaction negatively and significantly predict obesity
Conclusion: Findings demonstrate that mental health and body image are factors affecting weight gain in adolescent girls, indicating that these variables need to be considered in therapy programs aimed at prevention of obesity
ABSTRACT
Stress is not always a direct result of stressful conditions, but rather the way they are perceived. Thus individual variables that may be associated with perceived stress should be examined in stress studies. This study investigates the intermediary role of self-efficacy in relation with stress, glycosylated haemoglobin and health-related quality of life in patients with type2 diabetes. All women with diabetes in Yazd Diabetes Research Centre, in 2012, were considered and 80 women were selected by random sampling. They completed Shirer's self-efficacy scale questionnaire, depression, anxiety and stress scale [DASS], and ADDQ0L19 questionnaire. Then they were introduced to the lab for blood test. Data were analysed by SPSS software and stepwise regression method. Pearson correlation test results showed that the hemoglobin A1c [r = 0.35] and Quality of Life [r = -0.22] are associated with stress [P <0.05]. As so hemoglobin A1c [r = 0.83] and Quality of Life [r = 0.37] with variable of self efficacy are associated positively and significantly [P <0.05]. Results of stepwise regression also showed that self efficacy and stress scales 0.697 of variance hemoglobin A1c and 0.140 of variance of Quality of life explaining to do. The impact of stress on blood sugar and patients' health-related quality of life can be influenced by their self-efficacy; therefore it is suggested that an educational intervention is done to increase patients' self-efficacy to better cope with stress in their life
