Abstract: Objective To study the relationship of the feet length with the statures and body weights of Shui students in middle and primary schools,in order to provide evidence for the accumulation of physical anthropology data.Methods A total of 1 382 Shui nationality students (689 males and 693 females) aged from 6 to 16 were selected from middle and primary schools in Sandu County in Guizhou Province,and their feet length,statures and the body weights were measured to perform a statistical analysis.Results The foot length of the male increased from 17.10 cm to 23.44 cm,the female from 16.29 cm to 22.14 cm,and the average annual growth of male and female were 0.63 cm and 0.59 cm in students of age from 6 to 16,respectively.The male stature grew from 112.49 cm to 157.13 cm,and the female from 109.01 cm to 149.79 cm,and the average annual growth of male and female were 4.46 cm and 4.08 cm,respectively.The body weights of the male increased from 19.11 kg to 45.88 kg,and for female from 17.83 kg to 45.02 kg,and the average annual growth of weights of male and female were 2.68 kg and 2.72 kg,respectively.There were a positive correlation among the foot length,stature and body weight in all male and female groups(r=0.437-0.927,P <0.01).The total regression equation of feet length and statures,and body weights were calculated.For male,it was y=5.801x+17.001,y=3.677x-43.768 and for female,it was y=5.942x+15.592,y=3.836x-45.512 respectively.Conclusion There are positive correlation among the foot length,stature and body weight in middle and primary students of Shui nationality.The regression equations can be used to calculate the stature and body weight of Shui students in middle and primary schools.
