A cross-sectional study was conducted with 1,477 middle school students enrolled in the public school network in Salvador, Bahia, Brazil to assess the prevalence of overweight and obesity.
The sample was determined using a two-stage cluster sampling technique for selecting schools and classes. A posteriori error was estimated. The students were classified as overweight or obese according to the World Health Organization's 2007 classifications. They were also classified according to age, stage of sexual maturity, socioeconomic class and the presence of abdominal obesity.
Overall, 9.3% of the students were overweight and 6.4% were obese; therefore, 15.7% of the students were considered to have excess weight (obesity + overweight), at a 95% confidence interval. Abdominal obesity was found in 12.9% of all students and in 13% of those of normal weight. An association was found between excess weight and age < 14 years (p = 0.030) and abdominal obesity (p = 0.001).
Intervention programs should be implemented to prevent and treat obesity in childhood and adolescence. In addition, professionals working with individuals in this age group should be sensitized to this problem. The need to standardize the anthropometric indicators used in the different studies is also emphasized.
对巴西巴伊亚州萨尔瓦多市公立学校网络中的1477名中学生进行横断面研究，以评估超重和肥胖的患病率。
采用两阶段整群抽样技术确定样本，用于选择学校和班级。估计了事后误差。根据世界卫生组织2007年的分类标准，将学生分为超重或肥胖。还根据年龄、性成熟阶段、社会经济阶层和腹部肥胖情况对学生进行了分类。
总体而言，9.3%的学生超重，6.4%的学生肥胖；因此，在95%的置信区间内，15.7%的学生被认为体重超标（肥胖+超重）。在所有学生中，12.9%的学生存在腹部肥胖，体重正常的学生中这一比例为13%。发现体重超标与年龄<14岁（p = 0.030）和腹部肥胖（p = 0.001）之间存在关联。
应实施干预计划，以预防和治疗儿童及青少年肥胖。此外，与这个年龄段人群打交道的专业人员应提高对这一问题的认识。还强调了规范不同研究中使用的人体测量指标的必要性。
