Objective: To explore the relationship between the arch type and physical form, physical fit-ness, body fat and somatotype. Methods:Measure and type the arch of 382 male soldier in a certain army by foot-print ratio method; Routinely detect the results of height and weight, body fat, 100 and 5 000 meters running, standing jump;According to the international heath-carter method, ten indexes were measured and the somatotype were evaluated. Results:①382 samples, flatfoot 91, accounted for 23. 6%, the foot arch index 0. 60 + 0. 21;non-flatfoot 291 , 76 . 2%, arch index 1 . 14 +0 . 22 , t=22 . 83 , P=0 . 001;②Comparing the mean of the results of height, weight, BMI, body fat percentage,100 and 5 000 meters running, standing jump of the two groups( flatfoot and non-flatfoot) samples, t-text, P>0. 05; ③Assessed by the method of heath-carter shape, flatfoot group so-matotype mean is 2. 7 (0. 7) -4. 8 (1. 3) -2. 7 (0. 9), sam is 1. 5 (0. 9);non flatfoot group somatotype mean is 2. 3 (0. 7) -5. 0 (3. 1) -2. 4 (0. 9), sam is 1. 6 (1. 0);The distance of two groups`points in 3D space mean somatotypes is 0. 54; t-test of the two groups`somatotype mean, P>0. 05. Conclusions: Compared the flatfoot group with the control group, there is no significant difference in physical form, physical fitness, body fat and so-matotype. The increasingly high rate of flatfoot in healthy people is physical, but not flatfoot disease, and no need for surgery.

早产儿生后两周内营养供应对青春期身体组成及血压的影响

目的 充足的营养对早产儿至关重要.关于早期营养及其对后期生长影响的纵向信息十分有限.本研究的目的是确定早产儿的早期能量和蛋白质供应对青春期身体组成和血压的影响.方法 本研究于2007～2008年对36例男性青少年(12.3±1.7岁)和25例女性青少年(11.5±1.8岁)进行了调查,他们系出生于1989年10月1日至1995年12月31日之间胎龄23～34周、出生体重＜1850 g的早产儿.根据其出生后两周内的营养模式(肠内与肠外)、能量供应(每日＜70千卡/kg与每日≥70千卡/kg)及蛋白质供应情况(每日超过2.5 g/kg ≥5 d与每日超过2.5 g/kg＜5 d),将调查对象分组,比较各组青春期身高、体重、血脂、血压等的差异.结果 在控制出生体重和生理成熟度的基础上,婴儿期能量摄入每天≥70千卡/kg的青少年身高(163 ±11 cm)和体重(58±16 kg)大于能量摄入每天＜70千卡/kg的青少年(身高156±11 cm,体重49± 16 kg),差异有统计学意义(P＜0.05)；两组间血压与体脂百分含量未见明显差异.结论 婴儿期较高的能量摄入与青春期的体格大小相关,但并不会构成不利的风险因素,如血压升高或体脂增加.
