Nutritional status and somatotype features of primary and middle school students in the urban area of Baise,Guangxi

Objective To investigate the body composition in primary school， middle school， and high school students in urban area of Baise， Guangxi Zhuang Autonomous Region and explore their nutritional status and somatotype features. Methods The body composition of 1 247 primary and secondary school students （614 boys， 633 girls） was detected by MC-180 body composition tester， and their nutritional status and somatotype features were analyzed according to the body composition test result. Results The percentage of low-fat boys in primary school， middle school and high school was 12.9%， 15.1% and 26.5%， respectively， while the percentage of low-fat girls was 18.8%， 9.1% and 13.0%， respectively. The percentage of high-fat boys in primary school， middle school， and high school was 17%，11.9% and 6.1%， while that of the girls was 2.9%，2.4% and 3.8%. The somatotypes of boys in primary school were mainly standard， standard muscle type， and overweight type. However， middle school boys’ somatotypes were mainly standard type， standard muscle type， and insufficient exercise type. In high school， the somatotypes of boy were of the four types: standard，thin muscle， insufficient exercise and thin. Primary school girls’ somatotypes were of two types standard and standard muscle. Middle school girls’ somatotypes were mainly standard and insufficiente exercise. While in high school， the girls’ somatotypes were mainly insufficient exercise and standard. Conclusion In the urban area of Baise， Guangxi Zhuang Autonomous Region， the number of boys （from primary school to high schools） with high fat， obesity or low fat is relatively high. The polarization is obvious. In primary school， the number of girls with low fat is too high. Schools and families should appropriately intervene in the diet structure and physical exercise for primary to high school students， especially according to their nutritional status and body characteristics. We should prevent the polarization between low fat and obesity.
