Determine the prevalence of excess weight in preschoolers in Natal/RN and analyze the variables involved such as: gender, age, type of school (public and private) and city zones.
Transversal study was performed in 20 public and 20 private schools in Natal, Brazil, between August and December, 2004. A total of 3721 children, from 2 to 6 years of age were analyzed. Children whose BMI was > or = 85 percentile were considered as excess weight and those with BMI > or = 95 percentile as overweight .
Prevalence of excess weight found was 26.5% (95%CI=24.4-28.9), with 14.1% (95%CI=13.0-15.3) risk of overweight and 12.4% (95%CI=11.4-13.6) overweight. In overweight children there were more males (13.9%, 95%CI=12.4-15.6) than females (10.8%, 95%CI=9.4-12.4) (p<0.01, Prevalence ratio [PR]=1.29, 95%CI=1.08-1.53). Excess weight was found in 19.7% (95%CI=17.1-22.7) of public school students and in 32.5% (95%CI=29.3-35.9) of private school students (p<0.01, [PR]=1.64, 95%CI=1.47-1.84). Overweight prevalence was 7.1% (95%CI=6.0-8.4) and 17.1% (95%CI=15.5-18.8), respectively (p<0.01, [PR]=2.41, 95%CI=1.98-2.93). The East + South zones, areas with a better quality of life index, showed higher percentages of excess weight (p<0.01) and overweight (p<0.01) than the North +West zones.
Excess weight and overweight prevalence in preschoolers in Natal is high, mainly in private schools, showing the need to implement prevention and intervention programs.
确定纳塔尔/北里奥格兰德州学龄前儿童超重的患病率，并分析相关变量，如性别、年龄、学校类型（公立和私立）及城市区域。
2004年8月至12月间，在巴西纳塔尔的20所公立学校和20所私立学校开展了横向研究。共分析了3721名2至6岁的儿童。体重指数（BMI）大于或等于第85百分位数的儿童被视为超重，BMI大于或等于第95百分位数的儿童被视为肥胖。
超重患病率为26.5%（95%置信区间=24.4-28.9），肥胖风险为14.1%（95%置信区间=13.0-15.3），肥胖率为12.4%（95%置信区间=11.4-13.6）。肥胖儿童中男性（13.9%，95%置信区间=12.4-15.6）多于女性（10.8%，95%置信区间=9.4-12.4）（p<0.01，患病率比[PR]=1.29，95%置信区间=1.08-1.53）。公立学校学生中超重率为19.7%（95%置信区间=17.1-22.7），私立学校学生中超重率为32.5%（95%置信区间=29.3-35.9）（p<0.01，[PR]=1.64，95%置信区间=1.47-1.84）。肥胖患病率分别为7.1%（95%置信区间=6.0-8.4）和17.1%（95%置信区间=15.5-18.8）（p<0.01，[PR]=2.41，95%置信区间=1.98-2.93）。生活质量指数较高的东部+南部区域，超重（p<0.01）和肥胖（p<0.01）的比例高于北部+西部区域。
纳塔尔学龄前儿童超重和肥胖的患病率较高，主要集中在私立学校，表明有必要实施预防和干预项目。
