Abstract: Objective To investigate the prevalence of overweight and obesity among children and adolescents aged 6-18 years in Shandong province, in order to provide basis for the development of strategies and measures for the prevention and control of overweight and obesity in children and adolescents. Methods Data were extracted from physical examinations of primary and secondary school students of Shandong province in 2015.A total of 9 583 576 children aged 6-18 years were included in this study.The prevalence of overweight and obesity among school-age children in Shandong province was examined by age, gender and region, based on four national and international criteria.The agreement between the national criteria and the international one was also analyzed. Results Based on the national, international obesity task force (IOTF), centers for disease control and prevention (CDC) and world health organization (WHO) standard criteria, the prevalence rate of overweight in the above criteria was 17.5%,16.6%,13.9% and 17.6%,respectively; and the prevalence rate of obesity in the above criteria was 13.1%,7.2%,11.4% and 10.8%, respectively.The prevalence rates of overweight and obesity in boys were higher than those in girls, and higher in urban areas than those in rural areas.The prevalence rates of overweight and obesity kept stable rising with age in children aged 6-11 years, but the rates decreased rapidly in adolescents aged 12-18 years.There was high agreement among the national criteria and the three international criterias, with the corresponding weighted kappa values of 0.82 (China vs.CDC), 0.70 (China vs.IOTF) and 0.83 (China vs.WHO), respectively. Conclusion Childhood obesity has become an important public health issue in Shandong Province, more attention should be paid by the whole society.

摘要： 目的 分析山东省学龄期儿童青少年超重肥胖流行现况,为儿童青少年肥胖防治策略和措施的制定提供基础数据。方法 利用2015年山东省中小学生体检数据,共纳入9 583 576名6~18岁儿童青少年。利用国内外四种儿童青少年超重肥胖标准分析山东省学龄期儿童超重肥胖性别、年龄、城乡分布特征,并比较国内标准与国外标准间的一致程度。结果 基于中国肥胖问题工作组(中国标准)、国际肥胖问题工作组(IOTF标准)、美国疾病预防控制中心(CDC标准)和世界卫生组织(WHO标准)推荐的儿童青少年超重肥胖体重指数(BMI)筛查标准,山东省6~18岁儿童青少年总体超重检出率分别为17.5%、16.6%、13.9%和17.6%,肥胖检出率分别为13.1%、7.2%、11.4%、10.8%。男生超重肥胖检出率高于女生,城市高于农村。在6~11岁年龄组随年龄增长超重肥胖检出率呈平稳上升趋势,12~18岁年龄组呈迅速下降趋势。中国标准与其他三种国际标准之间一致性较好,加权Kappa值分别为0.82(中国标准vs.CDC标准)、0.70(中国标准vs.IOTF标准)和0.83(中国标准vs.WHO标准)。结论 儿童青少年肥胖已成为山东省重要的公共卫生问题,需引起全社会的重点关注。
