摘　　要：目的了解乌鲁木齐市7岁以下维吾尔族和汉族儿童体格发育情况,并计算脂肪重聚发生年龄。方法通过分层整群抽样的方法,于2015年6月抽取乌鲁木齐市7个区、1个县7岁以下9682名维汉(维吾尔族)儿童(男童5139人,女童4543人,汉族6152人,维族3530人),测量其身高、体重、坐高、头围、胸围,比较维汉民族男女童身高别体重(weight for height Z-score,WHZ)的差异,绘制维汉男女童WHZ曲线并通过双变量随机模型和自然增长模型推算维汉男女童脂肪重聚年龄并进行比较。结果不同年龄组的维汉男女童比较发现,低年龄组体格发育差异较为显著,并且在婴幼儿期各项体格发育指标均高于高年龄组儿童;在维、汉男童WHZ比较中,0月^(t=4.277,P<0.001)、6月^(t=2.133,P=0.033)、5岁^(t=2.278,P=0.023)、6~7岁(t=2.503,P=0.013)及各段合计组(t=5.238,P<0.001)差异均有统计学意义,维、汉女童WHZ比较中,0月^(t=2.533,P=0.011)和1岁~组(t=-2.141,P=0.033)差异有统计学意义。7岁以下维、汉男童超重和肥胖总体检出率高于女童(超重率:维族男童7.97%,女童5.46%,汉族男童12.55%,女童5.90%;肥胖率:维族男童5.58%,女童3.48%,汉族男童7.73%,女童3.92%),而维族女童超重-肥胖比(OOR=1.57)高于男童(OOR=1.43),汉族女童超重-肥胖比(OOR=1.50)低于男童(OOR=1.62)。经数学模型计算汉族男童脂肪重聚发生最早[3.94(95%CI 3.54~4.33)岁],其次为维族男童[4.17(95%CI 2.70~5.72)岁]和汉族女童[4.56(95%CI 4.14~4.99)岁],维族女童脂肪重聚发生最迟[5.57(95%CI 4.00~7.13)岁]。结论 2015年乌鲁木齐市7岁以下汉族儿童超重和肥胖发生率均高于维族儿童,且汉族儿童脂肪重聚年龄早于维吾尔族儿童。Objective To understand the physical development of Uygur and Han children under 7 years old in Urumuqi, and analyze the age of adiposity rebound.Methods Using stratified cluster sampling,9682 Uygur and Han children under 7 years old were selected in 7 districts and 1 county in Urumqi in June 2015,measuring their heights,weights,sitting heights,head circumference and chest circumference; comparingthe differences of weight for height Z-score（ WHZ）,drawing WHZ curves,calculating the adiposity rebound ages of Uygur and Han nationality boys and girls. Results The difference of physical development in low age groups was significant. There were significant differences in the WHZ of Uygur and Han boys in 0 month-（ t = 4. 277,P〈0. 001）,6 months-（ t = 2. 133,P = 0. 033）,5 years-（ t = 2. 278,P = 0. 023）,6-7 years（ t = 2. 503,P = 0. 013） and all ages combined（ t = 5. 238,P〈0. 001）,and significant differences exist in WHZ of Uygur and Han girls in 0 month-（ t = 2. 533,P =0. 011） and 1 year old-（ t =-2. 141,P = 0. 033）. The overall prevalence of overweight and obesity in boys was higher than that in girls under 7 years old（ overweight rate： Uygur boys 7. 97%,Uygur girls 5. 46%; Han boys 12. 55%,Han girls 5. 90%; obesity rate：Uygur boys 5. 58%,Uygur girls 3. 48%; Han boys 7. 73%,Han girls 3. 92%）,while overweight obesity ratio（ OOR） in Uygur girls were higher than Uygur boys（ girls OOR =1. 57,boys OOR = 1. 43） and OOR of Han girls was lower than that of boys（ girls OOR =1. 50,boys OOR = 1. 62）. Mathematical model indicated that the adiposity rebound age of Han boys was 3. 94 years old（ 95% CI 3. 54-4. 33）,Uygur boys was 4. 17 years old（ 95% CI 2. 70-5. 72） and Han girls was 4. 56 years old（ 95% CI 4. 14-4. 99）,and the adiposity rebound age of Uygur girls was 5. 57 years old（ 95% CI 4. 00-7. 13）.Conclusion The prevalence of overweight and obesity among Han children under seven years old is higher than that of Uygur children,and the age of fat rebound in Han
