To assess the prevalence of and the factors related to overweight and obesity in a sample of children from the region of Sintra, Portugal.
Cross-sectional study, stratified for freguesia with random selection of schools. Height, weight, triceps skinfold, upper arm and waist circumferences were measured, and overweight/obesity defined according to international criteria. Breast-feeding, number of daily meals and parents' height and weight data were also collected.
One thousand two hundred and twenty-five children aged 6-10 years were assessed. Overall prevalence of overweight and obesity was 35.6% (23% overweight and 12.6% obesity). Overweight or obese children had higher triceps skinfold, upper arm circumference, arm muscle area, and waist circumference than their normal weight counterparts (P < 0.001). On multivariate analysis, relatively to a child without obese progenitors, a child with one obese progenitor had an obesity risk multiplied by 2.78 (95% confidence interval (CI): 1.76-4.38), while a child with two obese progenitors had a risk multiplied by 6.47 (95% CI: 5.59-16.19). Conversely, being picky was significantly related with a smaller risk of obesity: for boys, odds ratio (OR) = 0.15 (95% CI: 0.04-0.63); for girls, OR = 0.19 (95% CI: 0.06-0.64). Finally, no relationships were found between obesity, birth weight, birth height or breast-feeding.
Prevalence of overweight and obesity are elevated among children of the Sintra region in Portugal compared to most other regions of Europe. The relationship with the parents' nutritional state stresses the need to target families for preventing obesity.
评估葡萄牙辛特拉地区儿童样本中超重和肥胖的患病率及相关因素。
横断面研究，按教区分层并随机选择学校。测量身高、体重、三头肌皮褶厚度、上臂围和腰围，根据国际标准定义超重/肥胖。还收集了母乳喂养情况、每日进餐次数以及父母的身高和体重数据。
对1225名6至10岁儿童进行了评估。超重和肥胖的总体患病率为35.6%（超重23%，肥胖12.6%）。超重或肥胖儿童的三头肌皮褶厚度、上臂围、上臂肌肉面积和腰围均高于正常体重儿童（P<0.001）。多因素分析显示，与没有肥胖祖代的儿童相比，有一个肥胖祖代的儿童肥胖风险乘以2.78（95%置信区间（CI）：1.76 - 4.38），而有两个肥胖祖代的儿童风险乘以6.47（95%CI：5.59 - 16.19）。相反，挑食与肥胖风险显著降低相关：男孩的比值比（OR）=0.15（95%CI：0.04 - 0.63）；女孩的OR = 0.19（95%CI：0.06 - 0.64）。最后，未发现肥胖与出生体重、出生身高或母乳喂养之间存在关联。
与欧洲大多数其他地区相比，葡萄牙辛特拉地区儿童中超重和肥胖的患病率较高。与父母营养状况的关系强调了针对家庭预防肥胖的必要性。
