Objective To assess the nutrition status of children and adolescents in China using the WHO growth reference （2007） in comparison with that defined by the International Obesity Task Force （IOTF） and the Working Group on Obesity in China （WGOC）. Methods Overweight and obesity were defined by age-, sex-, specific BMI reference developed by WHO （2007）, IOTF （2000）, and WGOC （2004）, respectively. Stunting and thinness were defined as height and BMI less than two standard deviations （SD） of the WHO growth reference （2007）, respectively. Data of children and adolescents aged 5 to 19 years （n=54 857, 28 273 boys, 26 584 girls） from the 2002 China National Nutrition and Health Survey （CNNHS） were used in the study. Results The prevalence of overweight, obesity, stunting and thinness among Chinese children and adolescents aged 5-19 years was 5.0%, 1.2%, 13.8%, and 7.4%, respectively when the WHO growth reference （2007） was used, whereas the estimated absolute total number affected by these 4 conditions were 14.6, 3.7, 40.6, and 21.8 million, respectively. The prevalence of overweight and obesity was 18.1% in large cities, while the stunting prevalence was 25.1% in rural 4. Obesity prevalence assessed by the WHO growth reference was higher than that as assessed by the IOTF reference, and obesity prevalence assessed by the WGOC reference was lower than that as assessed by the IOTF reference. Conclusion The nutritional status of children and adolescents is not equal in different areas of China. Stunting is still the main health problem of the poor, while overweight and obesity are the main health problems in large cities.

Objective To verify Working Group for Obesity in China （WGOC） recommended body mass index （BMI） classification reference for overweight and obesity in Chinese children and adolescents using the data of 2002 China Nationwide Nutrition and Health Survey. Methods PediaWic metabolic syndrome （MetS） and abnormality of each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia in adults was applied as well. The average level and abnormality rate of the metabolic indicators were described by BMI percentiles and compared with general linear model analysis. Receiver operating characteristic analysis was used to summarize the potential of BMI to discriminate between the presence and absence of the abnormality of these indicators. Results There was neither significantly increasing nor significantly decreasing trend of biochemical parameter levels in low BMI percentile range （〈65th）. Slight increasing trend from the 75th and a significant increase were found when BMI≥85th percentile. In general, the prevalence of the examined risk factors varied slightly when BMI percentile〈75th, and substantial increases were consistently seen when BMI percentile≥75th. As an indicator of hyper-TG, hypertension and MetS, the sensitivity and specificity were equal at the point of BMI〈75th percentile, and the Youden＇s index of risk factors also reached peak point before 75th percentile except for MetS. When the BMI percentile was used as the screening indicator of MetS, Youden＇s index reached peak point at 85th percentile, just the point in the ROC graph that was nearest to the upper left comer. Conclusion The BMI classification reference for overweight and obesity recommended by WGOC is rational to predict and prevent health risks in Chinese children and adolescents. Lower screening cut-off points, such as 83th percentile or 80th percentile, should not be excluded when they are considered as overweight criteria in future interventi

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, also called the Guo Shou jing Telescope) is a special reflecting Schmidt telescope. LAMOST’s special design allows both a large aperture (effective aperture of 3.6 m–4.9 m) and a wide field of view (FOV) (5°). It has an innovative active reflecting Schmidt configuration which continuously changes the mirror’s surface that adjusts during the observation process and combines thin deformable mirror active optics with segmented active optics. Its primary mirror (6.67m×6.05 m) and active Schmidt mirror (5.74m×4.40 m) are both segmented, and composed of 37 and 24 hexagonal sub-mirrors respectively. By using a parallel controllable fiber positioning technique, the focal surface of 1.75 m in diameter can accommodate 4000 optical fibers. Also, LAMOST has 16 spectrographs with 32 CCD cameras. LAMOST will be the telescope with the highest rate of spectral acquisition. As a national large scientific project, the LAMOST project was formally proposed in 1996, and approved by the Chinese government in 1997. The construction started in 2001, was completed in 2008 and passed the official acceptance in June 2009. The LAMOST pilot survey was started in October 2011 and the spectroscopic survey will launch in September 2012. Up to now, LAMOST has released more than 480 000 spectra of objects. LAMOST will make an important contribution to the study of the large-scale structure of the Universe, structure and evolution of the Galaxy, and cross-identification of multiwaveband properties in celestial objects.

目的比较称重法、回顾法和食物频率法在评估人群食物摄入量的差异和相关性。方法2002年中国居民营养与健康调查中同时使用称重法、24 h回顾法和食物频率法进行膳食调查的15-75岁的居民23 198名(男11 107名,女12 091名)。称重法入户称量调查对象全家过去3 d在家吃的所有食物重量;24 h回顾法回顾调查对象过去3 d每天在家及在外所消费的食物的种类和数量;食物频率法调查对象过去1年内所摄入的33类食物及油盐和调味品的摄入频率及摄入量。结果回顾法和称重法调查得出的平均每天食物摄入量比较接近;除水果和饮酒量外,其他食物摄入量与称重法的差异均在10％以内;低估和高估的个体的比例均比较少,60％以上的个体食物摄入量的估计值在称重法的±25％以内;回顾法得出的个体食物摄入量与称重法的结果均呈中高度正相关,相关系数在0．58-0．88之间。食物频率法得出的摄入频率较高的食物与称重法比较接近,米及其制品、面及其制品、其他谷类、豆类、蔬菜、坚果和油的摄入量与称重法的相对差异均在15％以内;食物频率法低估和高估的比例均比较高,一般在称重法的±25％以内的个体不足50％;食物频率法得出的食物摄入量与称重法呈低中度相关,相关系数在0．08-0．76之间。结论以称重法为标准的验证结果支持称重法修正24 h回顾法在群体以及个体中进行食物摄入量的调查。食物频率法可以反映群体及个体的食物摄入情况,尤其对消费频率较高的食物,比较适用研究膳食和健康的关系。
