GONZALEZ-ZAPATA, Laura Inés et al. Excess weight and economic, political, and social factors: an international ecological analysis. Cad. Saúde Pública [online]. 2011, vol.27, n.9, pp. 1746-1756. ISSN 1678-4464.
This study analyzed prevalence rates for excess weight in adults based on body mass index (BMI) and the association with various demographic, socioeconomic, and political variables (democracy index). An ecological design was used, including a total of 105 countries, with BMI data from 2000 to 2006. Other variables were obtained by proximity to the year of nutritional status. The study used the World Health Organization (WHO) classification for BMI. Spearman correlation coefficients and multiple logistic regression models were used. In both genders, overweight and obesity were correlated with calorie availability and the human development index (HDI) and its component variables. As for the variables related to democracy, there was an inverse correlation with weight, stronger in men than women. In conclusion, better living conditions in countries were directly associated with higher rates of excess weight in the population, with different patterns according to gender.
