This study aimed to evaluate the prevalence of overweight and obesity derived from measured data of weight and height in a cross-sectional sample of adolescents in the Italian region of Lazio and to analyse their association with different socio-demographic factors.
The study was conducted in a representative sample of 15-16-year-old adolescents recruited in secondary schools between December 2011 and May 2012. 369 adolescents were investigated. Body weight, height and waist circumference were measured. The BMI of each subject was calculated, and the prevalence of overweight and obesity was determined by age and sex using the IOTF reference values and WHO growth standards. Waist circumference/height ratio (WC/Ht) was calculated and the subjects were classified using the cut-off of 0.5: WC/Ht≥0.5 and WC/Ht<0.5. Selected socio-demographic characteristics were assessed via questionnaire.
The percentages of overweight and obesity were high, 15.4% and 7.9%, respectively, with significant difference between males and females (19.1% vs. 12.6% for overweight and 11.1% vs. 5.3% for obese) using the IOFT reference. The ratio WC/Ht≥0.5 was observed in 12.7% of the sample (all the obese and 29.8% of the overweight subjects). Multiple logistic regression analysis indicated that gender, school municipality, mother's employment status, and family structure had a significant effect on ponderal status (overweight/obesity vs. normal weight).
These findings show a high prevalence of body weight excess associated with socio-demographic factors in the Italian sample investigated, and the need for effective public health interventions to combact obesity with particular attention to disadvantaged adolescents.
本研究旨在通过对意大利拉齐奥地区青少年横断面样本的体重和身高测量数据评估超重和肥胖的患病率，并分析其与不同社会人口学因素的关联。
该研究在2011年12月至2012年5月期间从中学招募的15 - 16岁青少年代表性样本中进行。共调查了369名青少年。测量了体重、身高和腰围。计算了每个受试者的体重指数（BMI），并使用国际肥胖工作组（IOTF）参考值和世界卫生组织（WHO）生长标准按年龄和性别确定超重和肥胖的患病率。计算腰围/身高比（WC/Ht），并以0.5为切点对受试者进行分类：WC/Ht≥0.5和WC/Ht<0.5。通过问卷调查评估选定的社会人口学特征。
超重和肥胖的百分比很高，分别为15.4%和7.9%，使用IOFT参考值时，男性和女性之间存在显著差异（超重分别为19.1%对12.6%，肥胖分别为11.1%对5.3%）。在12.7%的样本中观察到WC/Ht≥0.5的比例（所有肥胖者以及29.8%的超重受试者）。多因素逻辑回归分析表明，性别、学校所在城市、母亲的就业状况和家庭结构对体重状况（超重/肥胖与正常体重）有显著影响。
这些发现表明，在所调查的意大利样本中，体重超标与社会人口学因素相关的患病率很高，并且需要有效的公共卫生干预措施来对抗肥胖，尤其要关注处境不利的青少年。
