Study on the body growth and components of university students in Shandong Province

Objective To understand the present state and the change trend of the body growth and components of university students in Shandong Province so as to provide evidence to elevate the health conditions of the students.Methods The heights,weights and circumferences of the students were measured according to the Detailed Testing Regulations of the Investigation of the Physique of Chinese Students.The thickness of skin fold of the triceps of upper right arms and the lower cornu of shoulder blades of the students was measured with the skin-fold caliper.The body density was estimated with the changing formula and BF% was estimated with the Brozek formula,and then the formulae,BF=BF%×weight and LBM=weight-BF,were calculated. Results Compared with the year 2000,the average heights of the urban male students,urban female students,rural male students and rural female students in 2005 increased respectively by 0.90 cm,1.32 cm,1.84 cm and 0.56 cm;the body components of the urban female students,rural male students and rural female students changed dramatically.Their BF% decreased by 1.30%,1.05% and(1.87%),respectively,P0.01.Conclusions In the recent 5 years,there has been an obvious change in the physical growth and body components of the university students in Shandong Province.Consequently,the hygiene measures should be established according to the characteristics of their physical growth.
