【摘要】：目的了解2000—2014年上海市學(xué)齡兒童青少年體質(zhì)量指數(shù)(BMI)的變化趨勢,為兒童青少年超重、肥胖判別標(biāo)準(zhǔn)研制及預(yù)防干預(yù)提供參考。方法選取2000,2005,2010,2014年4次全國學(xué)生體質(zhì)與健康調(diào)研中7~18歲兒童青少年作為研究對象。應(yīng)用最小均方(Least Mean Square,LMS)法探討不同性別、年齡組兒童青少年BMI的變化趨勢。結(jié)果14年間學(xué)生BMI P_(85)低年齡組差異比較小,隨年齡增加差異逐漸增大,青春期后有減小的趨勢,男生平均增加2.1百分點(diǎn),女生平均增加1.3百分點(diǎn)。學(xué)生BMI增長主要集中在中等和高百分位數(shù),尤其是P_(90)后,差值逐漸增大。7~11,12~15歲男生在P_(50)后差值均逐漸增大,P_(95)分別達(dá)2.0,3.2百分點(diǎn),其中12歲男生從23.4 kg/m~2增加到26.8 kg/m~2,14歲女生從24.0 kg/m~2增加到25.9 kg/m~2。與WGOC標(biāo)準(zhǔn)相比,2014年男生BMI P_(85),P95均較高,而女生BMI P_(85)10歲之前高于WGOC標(biāo)準(zhǔn),從11歲開始與WGOC標(biāo)準(zhǔn)基本相一致。2014年上海市7~18歲兒童青少年超重、肥胖檢出率分別為15.4%,9.1%,較2000年總體均呈上升趨勢,分別上升6.4,5.2百分點(diǎn)。結(jié)論 BMI分布高百分位的個體比低百分位個體的變化更大。在肥胖防治工作中,加強(qiáng)對群體BMI曲線的監(jiān)測分析,對適時調(diào)整宏觀調(diào)控戰(zhàn)略意義重大。
[Abstract]:Objective to investigate the trend of body mass index (BMI) of school-aged children and adolescents in Shanghai from 2000 to 2014, and to provide a reference for the development of discriminant criteria for overweight and obesity among children and adolescents and for the prevention and intervention. Methods 7- and 18-year-olds were selected as the subjects in the study of physical fitness and health of students in 2005 and 2010, and in 2014, 4 times in the National Survey of students' physique and Health. Using the method of least mean square Mean (LMS), the change trend of BMI in children and adolescents of different sex and age group was studied. Results the difference of BMI Pai 85 in the lower age group was small, and the difference gradually increased with the increase of age, and decreased after puberty. The average increase of male students was 2.1 percentage points, and the average increase of female students was 1.3 percentage points. The increase in student BMI was mainly concentrated in the middle and high percentiles, especially after PSTL 90), and the difference gradually increased. The difference between students aged 15 and 15 years old gradually increased after Pill 50) and the difference between them gradually increased to 2.0% or 3.2% respectively. Among them, 12-year-old boys increased from 23.4 kg/m~2 to 26.8 kg / mMN, and 14-year-old girls increased from 24.0 kg/m~2 to 25.9 kg / mm2. Compared with the WGOC standard, in 2014, the male students were higher than the WGOC standard, while the female students were higher than the WGOC standard before the age of 10, and were basically consistent with the WGOC standard from the age of 11. In 2014, the 718-year-olds in Shanghai were overweight. The prevalence rate of obesity was 15.4% and 9.1% respectively, which was increased by 6.4% or 5.2% as compared with that in 2000. Conclusion the change of BMI distribution in individuals with high percentile is greater than that with low percentile. In the prevention and treatment of obesity, it is of great significance to strengthen the monitoring and analysis of population BMI curve for timely adjustment of macro-control strategy.
