Objective: To explore the rules of subcutaneous fat development in Dalian. Methods: Shao Qing-qing’s anthropometric method was used to investigate the skinfold thickness and body fat development of the upper arm triceps and subscapularis of 1190 primary and secondary school students in Dalian. Results: With age, the skinfold of the male limb became thinner while the skinfold of the trunk became thicker while the female skin of the limb and thigh were thicker. Body fat of boys increased year by year before puberty, but decreased year by year after puberty. Body fat of girls increased with age and increased rapidly after puberty. The skinfold thickness of girls in all age groups were greater than boys, and more obvious after 13 years of age. Conclusion: The differences in age and sex of subcutaneous fat development among Han students in Dalian are related to the stage of physical and mental development of children and adolescents.
