【摘要】：目的 1.通過分析1985年、2000年和2005年蒙古族7-18歲學(xué)生體重調(diào)研情況,了解20年來蒙古族7～18歲兒童青少年體重分布及變化趨勢(shì)； 2.以2000年蒙古族7～18歲學(xué)生體重為指標(biāo)進(jìn)行有序樣品聚類分析,并用2005年蒙古族學(xué)生體質(zhì)調(diào)研數(shù)據(jù)進(jìn)行回代驗(yàn)證,建立合理適用的蒙古族7～18歲兒童青少年不同年齡段體重參考值； 3.將為臨床診斷及學(xué)校衛(wèi)生工作中制定有效地干預(yù)策略與措施提供科學(xué)依據(jù)。 方法 對(duì)象來自“全國學(xué)生體質(zhì)健康調(diào)研”蒙古族通遼校點(diǎn)1985年、2000年和2005年的調(diào)查數(shù)據(jù)。1985年獲得有效人數(shù)5767人,2000年獲得有效人數(shù)5563人,2005年獲得有效人數(shù)2990人,數(shù)據(jù)資料采用SPSS數(shù)據(jù)庫進(jìn)行統(tǒng)一分析,通過單因素對(duì)城鄉(xiāng)間、性別間、年齡間、1985年與2005年間做對(duì)比分析,以觀察某因素的分布情況、變化特征、對(duì)比差異及發(fā)展趨勢(shì)等。選用2000年有效人數(shù)體重指標(biāo)數(shù)據(jù)資料,采用有序樣品聚類分析方法進(jìn)行聚類分析,找出最優(yōu)分割即劃分最優(yōu)年齡段,統(tǒng)計(jì)出每個(gè)最優(yōu)年齡段的均數(shù)和標(biāo)準(zhǔn)差,建立各年齡段體重的參考值范圍。之后,以2005年有效人數(shù)體重?cái)?shù)據(jù)資料對(duì)其進(jìn)行回代驗(yàn)證參考值范圍外驗(yàn)率。 結(jié)果 1.1985年、2000年和2005年蒙古族7～18歲學(xué)生體重水平基本均隨年齡的增長而增長,除1985年蒙古族7～18歲學(xué)生體重城市男生17歲到18歲未增長,基本符合生長發(fā)育的一般規(guī)律。1985年到2005年,7～18歲蒙古族城市男生、鄉(xiāng)村男生、城市女生和鄉(xiāng)村女生的體重平均增長值為5.44kg、4.52kg、3.83kg和3.17kg。其中城市、鄉(xiāng)村男生前15年年平均增長值為5.57kg和4.34kg,各年齡組增長值均有統(tǒng)計(jì)學(xué)意義；城市女生前15年年平均增長值為3.79kg,除17歲組外各年齡組增長均有統(tǒng)計(jì)學(xué)意義；鄉(xiāng)村女生前15年平均增長3.29kg,7～15歲增長有統(tǒng)計(jì)學(xué)意義。后5年除城市男生14歲組下降3.43kg,鄉(xiāng)村男生除11歲組增長2.46kg,城市女生8歲組增長2.25kg,其余年齡組均無統(tǒng)計(jì)學(xué)意義。體重以年增長值3kg為快速增長標(biāo)準(zhǔn),20年來城鄉(xiāng)男女生體重有快速增長期變化趨勢(shì)。20年平均增長量城男鄉(xiāng)男城女鄉(xiāng)女,城鄉(xiāng)男女生的10年增長量均大于0.5kg。前15年增長顯著,后5年增長趨緩。同時(shí)城市男生1985年、2000年、2005年體重最大生長量年齡分別為13～14歲、13～14歲、12～13歲；城市女生分別為11～12歲、11～12歲、10～11歲；鄉(xiāng)村男生分別為14～15歲、12～13歲、12～13歲；鄉(xiāng)村女生分別為12～13歲、11～12歲、10～11歲。20年來城鄉(xiāng)男女生體重最大生長量年齡均有提前趨勢(shì),突增高峰20年來有提前趨勢(shì),突增期城市學(xué)生有所延長,鄉(xiāng)村學(xué)生有所縮短。 2.兒童青少年的生長發(fā)育是一個(gè)連續(xù)性過程,考慮其生長發(fā)育特點(diǎn)和突增期變化,根據(jù)體重對(duì)蒙古族7-18歲學(xué)生年齡進(jìn)行了不同性別、不同城鄉(xiāng)最優(yōu)年齡段劃分。按城男、鄉(xiāng)男、.城女、鄉(xiāng)女分別對(duì)蒙古族7-18歲兒童青少年體重變化進(jìn)行年齡段劃分,采用最優(yōu)分割法,當(dāng)城男與鄉(xiāng)男類別數(shù)均為5時(shí)、城女與鄉(xiāng)女類別數(shù)均為6時(shí),與下一個(gè)分類時(shí)最小誤差函數(shù)e[P(c,k)]比值較小,且處于較穩(wěn)定狀態(tài),城男與鄉(xiāng)男、城女與鄉(xiāng)女分別為：1.4134與1.6111、1.3519與1.7210。結(jié)合本專業(yè)知識(shí),認(rèn)為城男與鄉(xiāng)男均5分類為宜,即1、3、6、8、10與1、4、7、9、11分割點(diǎn),城女與鄉(xiāng)女均6分類為宜,即1、3、5、6、8、10分割點(diǎn)；城男分為7～8歲、9～11歲、12～13歲、14～15歲、16～18歲等5個(gè)最佳年齡段；鄉(xiāng)男分為7～9歲、10～12歲、13～14歲、15～16歲、17～18歲等5個(gè)最佳年齡段；城女及鄉(xiāng)女劃分為7～8歲,9～10歲,11歲,12～13歲,14～15歲,16～18歲等6個(gè)最佳年齡段,建立了蒙古族兒童青少年的體重參考值,共計(jì)32個(gè)參考值。 3.用2005年蒙古族學(xué)生體質(zhì)調(diào)研數(shù)據(jù)進(jìn)行回代驗(yàn)證,得到城市男生的外驗(yàn)率最低為91.71%,最高為97.69%,平均外驗(yàn)率為94.23%；鄉(xiāng)村男生的外驗(yàn)率最低為90.84%,最高為100.0%,平均外驗(yàn)率為95.25%；城市女生的外驗(yàn)率最低為91.71%,最高為98.44%；平均外驗(yàn)率為94.23%；鄉(xiāng)村女生的外驗(yàn)率最低為93.37%,最高為98.44%；平均外驗(yàn)率為95.47%,均達(dá)到了要求(≥85%)。 結(jié)論 本研究所建立的針對(duì)蒙古族兒童青少年不同年齡段的體重參考值,突出了簡(jiǎn)單實(shí)用的特點(diǎn),同時(shí)填補(bǔ)了蒙古族兒童青少年年齡別體重標(biāo)準(zhǔn)的缺乏,對(duì)預(yù)防蒙古族兒童青少年的營養(yǎng)不良、超重和肥胖有一定的指導(dǎo)意義,為制定學(xué)校衛(wèi)生和兒童保健工作的策略和措施提供科學(xué)依據(jù)。

1. Through the analysis of the weight survey of Mongolian students aged 7-18 in 1985, 2000 and 2005, to understand the weight distribution and change trend of Mongolian children aged 7-18 in the past 20 years.
2. Taking the weight of Mongolian students aged 7-18 in 2000 as the index, the orderly sample clustering analysis was carried out, and the data of Mongolian students'physique survey in 2005 were used to verify the validity of this method.
3., it will provide a scientific basis for formulating effective intervention strategies and measures in clinical diagnosis and school health work.
Method
The subjects were collected from the National Survey of Physical Fitness and Health of Students in Tongliao School of Mongolian Nationality in 1985, 2000 and 2005. The effective number was 5767 in 1985, 5563 in 2000 and 2990 in 2005. The data were analyzed by SPSS database. The data were analyzed by single factor between urban and rural areas and between genders. In order to observe the distribution, change characteristics, contrast differences and development trend of some factors, the data of effective body weight index in 2000 were selected and clustering analysis of ordered samples was carried out to find out the optimal segmentation, i.e. dividing the optimal age group, and counting out the optimal age group. The average and standard deviation of each segment were used to establish the reference range of body weight for each age group.
Result
1. In 1985, in 2000 and 2005, the body weight level of Mongolian students aged 7-18 basically increased with age, except that in 1985, the body weight of Mongolian students aged 7-18 did not increase among urban boys aged 17-18, which basically accorded with the general law of growth and development. The average growth value of female students'body weight was 5.44 kg, 4.52 kg, 3.83 kg and 3.17 kg. The average annual growth rate was 3.29 kg, and the growth rate was statistically significant between the ages of 7 and 15. In the last five years, except urban boys aged 14, rural boys aged 11 and urban girls aged 8, the growth rate was 2.46 kg and 2.25 kg respectively. The average growth rate in the past 20 years was more than 0.5 kg in both urban and rural areas. The growth rate was significant in the first 15 years, but slowed down in the next 5 years. Rural boys were 14-15, 12-13 and 12-13 years old, while rural girls were 12-13, 11-12 and 10-11 years old, respectively.
2. The growth and development of children and adolescents is a continuous process. Considering the characteristics of growth and development and the change of sudden increase period, the age of Mongolian 7-18 year-old students is divided into different sex and optimal age groups in urban and rural areas according to their weight. When the number of urban and rural men is 5 and the number of urban and rural women is 6, the ratio of the minimum error function E [P (c, k)] is small and stable with the next classification. Urban and rural men, urban and rural women are 1.4134 and 1.6111, 1.3519 and 1.7210, respectively. Males and townsmen are classified into 5 categories, i.e. 1,3,6,8,10 and 1,4,7,9,11 segmentation points; urban and rural women are classified into 6 categories, i.e. 1,3,5,6,8,10 segmentation points; urban men are classified into 5 optimal age groups: 7-8 years old, 9-11 years old, 12-13 years old, 14-15 years old, 16-18 years old; rural men are classified into 5 optimal age groups: 7-9 years old, 10-12 years old, 13-14 years old, 15-16-16 years old, 17-18 years old. The reference values of body weight for Mongolian children and adolescents were established, which were divided into 6 optimum age groups: 7-8 years old, 9-10 years old, 11 years old, 12-13 years old, 14-15 years old, 16-18 years old.
3. Using the data of the physical fitness survey of Mongolian students in 2005, we find that the lowest and highest ex-perience rate of urban boys is 91.71%, 97.69% and 94.23% respectively; the lowest and highest ex-perience rate of rural boys is 90.84%, 100.0% and 95.25% respectively; the lowest and highest ex-perience rate of urban girls is 91.71% and 98.44% respectively; The average out-of-lab rate was 94.23%; the lowest out-of-lab rate was 93.37% and the highest was 98.44%; and the average out-of-lab rate was 95.47%, which met the requirements (> 85%).
conclusion
The reference value of body weight for different age groups of Mongolian children and adolescents established in this study has highlighted the simple and practical characteristics and filled in the lack of age-specific weight standards for Mongolian children and adolescents. It has certain guiding significance for preventing malnutrition, overweight and obesity among Mongolian children and adolescents, and for formulating school hygiene and obesity. The scientific basis for strategies and measures for child health care is provided.
