    ¡¾Abstract¡¿ AIM: To offer an integrated assessment method in assessing male recruit youth¡¯s constitution status. METHODS: 4110 male recruit youth from 3 districts in Zhejiang Province were assessed by cluster sampling. Six indexes, including body mass (mB)/height (hB), chest circumference/hB, vital capacity/mB, heart function index, standing long jump and pushª²up, were used to classify the youth by clustering analysis. According to the differences between different classes, the weight of each index was calculated. The individual constitution scores were computed and evaluated. RESULTS: Three classes were classified by quick clustering and significant differences were found between different classes. The constitution of Type¢ñwas worse than Type II and Type III significantly. The weights of mB/hB, chest circumference/hB, vital capacity/mB, heart function index, standing long jump and pushª²up were 0.3556, 0.1789, 0.1179, 0.0140, 0.1295 and 0.2041, respectively. The constitution scores in different classes were significantly different. The youth were classified into two groups of normal and worse constitution, with the dividing point -0.79, which was the 95% oneª²sided reference range critical point of constitution score. Compared with the clustering classes, most of the youth in worse constitution group were in Class¢ñ, matching the result that the youth¡¯s constitution in Class¢ñ was worse. CONCLUSION: By computing the weight of each index using the differences between different clustering classes and evaluating the constitution according to the constitution score, we can easily obtain some reference for the constitution evaluation of recruited youth. ......
