【摘要】 目的：探讨中国10～19岁儿童青少年营养状况的地理分布特征，为促进儿童青少年身体健康提供参考。方法：以2020年“中国家庭追踪调查”数据为基础，结合地理信息系统技术（ArcGIS），分析中国儿童青少年营养状况地理分布。结果：儿童青少年消瘦、正常、超重和肥胖检出率分别为21.84%、68.83%、9.33%、6.98%，其中男生的消瘦、超重和肥胖检出率均高于女生；地理分布图显示，儿童青少年超重和肥胖的分布总体表现为北方高于南方，黑龙江、北京和上海的超重和肥胖检出率都较高；消瘦分布表现为南方整体高于北方，其中广东、广西、湖南消瘦检出率较高；四大经济分区中东北地区肥胖率（9.92%）和超重率（13.99%）最高，消瘦率最低。结论：中国10～19岁儿童青少年营养状况地理分布具有明显的南北地域差异和经济区域差异。更多还原

【Abstract】 Objective: To explore the geographical distribution of Characteristics of nutritional status of children and adolescents aged 10～19 in China, so as to provide reference for promoting the health of children and adolescents.Methods: Based on the data of the "China Family Tracking Survey" in 2020, combined with the geographic information system technology(ArcGIS), the geographical distribution of the nutritional status of children and adolescents in China was analyzed. Results: The detection rates of emaciation, normal, overweight and obesity in children and adolescents are 21.84%, 68.83%, 9.33% and 6.98% respectively, among which, the detection rates of emaciation, overweight and obesity in boys is higher than those in girls. The geographical distribution map shows that the overall distribution of overweight and obesity in children and adolescents is higher in the north than in the south, and the detection rates of overweight and obesity are higher in Heilongjiang, Beijing and Shanghai. The distribution of emaciation is higher in the south than in the north, and the detection rate of emaciation is higher in Guangdong, Guangxi and Hunan. Among the four major economic regions,in Northeast China, the obesity rate(9.92%) and overweight rate(13.99%) are the highest, and the emaciated rate is the lowest.Conclusion: The geographical distribution of nutritional status of children and adolescents aged 10～19 in China has obvious north-south differences and economic regional differences.更多还原
