Associação entre aspectos psicossociais e excesso de peso em adultos de um município de médio porte do Sul do Brasil

Abstract

The objective of this study was to investigate the association between psychosocial factors and self-reported overweight. A cross-sectional study was carried out with 1100 adults of a

Brazilian city. Structured interviews were conducted using a standard pre-tested questionnaire. Overweight was referred by the participants and defined as Body Mass Index

25 kg/m². Psychosocial factors were quality of life (WHO-8:EUROHIS) and social support (Medical Outcomes Study). Crude and adjusted prevalence ratios (PR) were obtained by

Poisson regression with robust variance and adjustment for design effect. After controlling for sociodemographic and behavioral variables, the prevalence of overweight in people reporting low quality of life and low social support was 19% (IC95% 1,03-1,38) and 12% (IC95% 0,96-1,31) higher than those reporting high/moderated quality of life and high/moderate social support, respectively. The findings suggest that psychosocial factors may be an important

determinant of self assessed overw
