Abstract

PurposeThe purpose of this paper is to assess the association between socioeconomic status and child overweight/obesity in Portugal and to evaluate income-related inequalities in its distribution.Design/methodology/approachData come from the last Portuguese National Health Survey (2005/2006) – sample of 6,903 observations. To define child overweight/obesity, the International Obesity Task Force cut-offs for body mass index (BMI) were used; the logistic regression analysis was adopted to explain the risk of overweight/obesity and inequality was measured by means of concentration curve and index.FindingsThe evidence obtained points to income-related inequalities in child overweight/obesity favourable to the better-off. The probability of child overweight/obesity was lower for higher income households, but up to a certain point a positive association between income and caloric food intake was found. The concentration index obtained was −0.072 (p-value<0.001).Research limitations/implicationsSome data limitations, no information on: physical exercise; sleeping habits; parents’ education and BMI; age is coded in groups.

The middle income effect is an issue raised in this work which deserves further investigation.
