| Résumé : | [BDSP. Notice produite par INIST-CNRS 0M1LR0xp. Diffusion soumise à autorisation]. Objectives : To see if obesity, deaths from diabetes, and daily calorie intake are associated with income inequality among developed countries. Design : Ecological study of 21 developed countries. Countries : Countries were eligible for inclusion if they were among the top 50 countries with the highest gross national income per capita by purchasing power parity in 2002, had a population over 3 million, and had available data on income inequality and outcome measures. Main outcome measures : Percentage of obese (body mass index>30) adult men and women, diabetes mortality rates, and calorie consumption per capita per day. Results : Adjusting for gross national per capita income, income inequality was positively correlated with the percentage of obese men (r=0.48, p=0.03), the percentage of obese women (r=0.62, p=0.003), diabetes mortality rates per 1 million people (r=0.46, p=0.04), and average calories per capita per day (r=0.50, p=0.02). Correlations were stronger if analyses were weighted for population size. The effect of income inequality on female obesity was independent of average calorie intake. Conclusions : Obesity, diabetes mortality, and calorie consumption were associated with income inequality in developed countries. Increased nutritional problems may be a consequence of the psychosocial impact of living in a more hierarchical society. |
