The present study evaluates trends in the prevalence of overweight and obesity in relation to gender and area of residence between two cohorts of students aged 11–13 years in Sicily. The analysis was performed on 1,839 schoolchildren, with 924 and 915 children being studied in 1999–2001 and 2009–2010, respectively. The children who were enrolled during 2009–2010 had significantly higher body mass indexes BMI, BMI z-scores, and waist circumferences than the children who were studied during 1999–2001 p<0.0001 for all; these differences was also observed when the cohort was subdivided according to gender or residence area The prevalence of obesity increased significantly from 7.9% in 1999–2001 to 13.7% in 2009–2010 p<0.0001, whereas thinness decreased significantly from 10.1% to 2.3% p<0.0001 in the same periods. The increase of trends in the prevalence of obesity was significantly higher in males 9.7% vs. 17.6%, p = 0.0006 than in females 6.3% vs. 9.8%, p = 0.04 and was slightly higher in urban areas 8.8% vs. 14.3%, p = 0.002 than in rural areas 7.8% vs. 13.0%, p = 0.012. The male gender was associated with a higher risk of being overweight or obese odds ratio: 1.63; 95% confidence intervals: 1.24–2.15; p = 0.0005 in 2009–2010 than in 1999–2001, after adjusting for age and the residence area. In conclusion, this study showed an increasing trend in the prevalence of overweight and obesity in Sicilian schoolchildren during the last decade and that this trend was related to gender, age and the area of residence. More specifically, our data indicated that the prevalence of obesity increased by 5.8%, the prevalence of thinness decreased by 7.8% and the prevalence of normal-weight children did not change over the course of a decade. These results suggest a shift in the body weights of Sicilian children toward the upper percentiles.
