Overweight and obesity are among the most prevalent nutritional problems in developed and developing countries. In this descriptive study, we attempted to determine the prevalence of overweight and obesity in Iranian adolescent girls attending high school in Tabriz. A sample of 1,650 (final study group, 1,518) high-school girls aged 14 to 20 years was selected by stepwise random sampling from five districts of Tabriz. Overweight and obesity were defined according to body mass index (BMI) percentiles from the First National Health and Nutrition Examination Survey (NHANES I) and the International Obesity Task Force (IOTF) BMI cutoffs. According to the NHANES I criteria, 14.6% of the study subjects were overweight or obese. Overweight and obesity was seen in 11. 1% and 3.6% of the students, respectively. By the IOTF cutoffs, 14% of the subjects were overweight or obese. Overweight and obesity were seen in 10.1% and 3.9% of the students, respectively. Of the study subjects, 8% had a BMI below the 15th percentile of NHANES I, an indicator of underweight. The prevalence of overweight and obesity in Tabriz high-school girls is higher than in many, but not all, parts of Iran, but lower than in some neighboring countries such as Saudi Arabia. In this age group, in addition to overweight and obesity, underweight (BMI < or = 15th percentile) is also present.
超重和肥胖是发达国家和发展中国家最普遍的营养问题之一。在这项描述性研究中，我们试图确定大不里士市高中阶段伊朗少女超重和肥胖的患病率。通过逐步随机抽样从大不里士的五个区选取了1650名（最终研究组为1518名）年龄在14至20岁的高中女生。超重和肥胖是根据首次全国健康和营养检查调查（NHANES I）的体重指数（BMI）百分位数以及国际肥胖特别工作组（IOTF）的BMI临界值来定义的。根据NHANES I标准，14.6%的研究对象超重或肥胖。超重和肥胖分别出现在11.1%和3.6%的学生中。按照IOTF临界值，14%的对象超重或肥胖。超重和肥胖分别出现在10.1%和3.9%的学生中。在研究对象中，8%的人的BMI低于NHANES I的第15百分位数，这是体重过轻的一个指标。大不里士高中女生超重和肥胖的患病率高于伊朗许多地区，但并非全部地区，不过低于一些邻国，如沙特阿拉伯。在这个年龄组中，除了超重和肥胖外，体重过轻（BMI≤第15百分位数）的情况也存在。
