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.
本研究评估了西西里岛两个年龄在 11-13 岁的学生队列中，超重和肥胖的流行率与性别和居住区域的关系。共分析了 1839 名儿童，其中 924 名和 915 名儿童分别于 1999-2001 年和 2009-2010 年进行了研究。与 1999-2001 年相比，2009-2010 年入学的儿童的体重指数（BMI）、BMI 得分和腰围明显更高（所有 p<0.0001）；当按性别或居住区域细分队列时，也观察到了这些差异。肥胖的患病率从 1999-2001 年的 7.9%显著上升到 2009-2010 年的 13.7%（p<0.0001），而消瘦的患病率从 10.1%显著下降到 2.3%（p<0.0001）。在同一时期，男性肥胖患病率的上升趋势明显高于女性（9.7%比 17.6%，p=0.0006），城市地区（8.8%比 14.3%，p=0.002）略高于农村地区（7.8%比 13.0%，p=0.012）。与 1999-2001 年相比，2009-2010 年男性超重或肥胖的风险更高（优势比：1.63；95%置信区间：1.24-2.15；p=0.0005），调整年龄和居住区域后。总之，本研究显示，在过去十年中，西西里岛学龄儿童超重和肥胖的流行率呈上升趋势，这种趋势与性别、年龄和居住区域有关。具体来说，我们的数据表明，肥胖的患病率增加了 5.8%，消瘦的患病率下降了 7.8%，正常体重儿童的患病率在十年内没有变化。这些结果表明，西西里儿童的体重向较高百分位转移。
