Abstract

MEDRANO-VAZQUEZ, Monserrat et al. Association of body mass index and self-control with healthrelated quality of life in overweight/obese people. Psychol. av. discip. [online]. 2014, vol.8, n.1, pp.13-22. ISSN 1900-2386.

The aim of this study was to identify the association of self-control with health-related quality of life and the possible mediation of the Body Mass Index (BMI). A predictive cross-sectional study was conducted. Participated 273 adults, users of a primary health care center in Mexico City, aged 18 to 65 years, with a BMI greater than 25. The SF-12 V1 and the Tangney, Baumeister and Boone's Self-Control Scale were applied. The results showed a significant association between self-control to physical and mental health quality of life; BMI was associated with physical quality of life. No associations were found between BMI to mental quality of life and self-control. There were no evidence of a mediation effect of BMI on the relationship between self-control and health-related quality of life. The results suggest that an overweight or obese person with greater self-control has better perception of physical and emotional well-being, independently of BMI.
