PURPOSE: To provide national, population-based estimates of the prevalence of overweight and obesity in the Italian population. METHODS: Prevalence estimates of overweight and obesity were calculated in seven waves (2001-2008) of the cross-sectional Multipurpose Household Survey organized by the Italian National Institute of Statistics, which are representative of the general adult Italian population. Sampling weights were used to estimate prevalence figures as well as their standard errors. Mean-difference plot was used to evaluate changes in the distribution of body mass index across sex and age categories. RESULTS: Almost half of Italian men and about 1 of 3 Italian women are overweight or obese. Between 2001 and 2008 the age-standardized prevalence of overweight (obesity) increased 1.4% (1.9%) in men and 0.4% (0.5%) in women. Mean-difference plots showed an upward shift for body mass index distribution with an increasing skewness. CONCLUSIONS: The obesity epidemic is one of the major issues in United States and other developed countries. However, if for "epidemic" we mean that in Italy obesity is steadily increasing, then our data give little support to this interpretation. In fact, trends observed between 1983 and 2008 suggest that the rates of changes in the prevalence of overweight and/or obesity are not increasing. Copyright (c) 2010 Elsevier Inc.
