Abstract
INTRODUCTION
obesity is a disease that affects a high percentage of the world's population. Although its origin is multicausal and multifactorial, less attention has been paid to psychological and behavioral variables.
AIM
to determine whether psychological variables (weight stigma, stress and depressive symptomatology) and behavioral variable (Mediterranean diet index) predict obesity according to body mass index (BMI), controlling for the effect of physiological variables (HDL cholesterol, triglycerides, glucose and blood pressure) and sociodemographic variables (sex, income, educational level).
METHODS
non-experimental, cross-sectional, correlational design. By means of a non-probabilistic convenience sampling, 344 persons were selected from the general Chilean population from the Araucanía region (Mage = 55.7 years; SD = 5.1 years; 55.8 % women). A blood sample, anthropometric measurement of weight and height, and self-report measures of psychological and behavioral variables were obtained.
RESULTS
a 5-block hierarchical multiple regression analysis was performed. Sociodemographic covariates did not significantly predict BMI, however physiological covariates, the behavioral variable and weight stigma, were significantly associated with BMI, with weight stigma being the predictor that explained the most variance.
CONCLUSIONS
the findings allow us to verify the role of psychological and behavioral variables in the multifactorial etiology of obesity. The findings are discussed in the light of the biopsychosocial approach, and a multidisciplinary approach to obesity is suggested.
