An Analysis of Hubei Junior Middle School Students' Morphological Function Development

Objective To analyze data of middle school students' morphological function indexes, and to provide basis for students' growth and development research and health improvement. Method Data of the Chinese Students' Constitution and Health Investigation During 1991 - 2000 in Hubei province were analyzed by the methods of comparing, mathematics statistics. Result The students morphological development indexes improved apparently, but the vital capacity decreased. The average increment was 0.37 cm for county boys body height, and 0.64 kg, 0.36 kg, 1.28 kg for city or county boys' and city girls' weight respectively. The boys' chest circumference average increment was 1.62 cm and 2.49 cm for city and county respectively. The decrease of vital capacity was 172.67 mL, 338.82 mL, 130.51 mL and 359.24 mL for city boys and girls and county boys and girls.Conclusion The morphological development improved apparently while their vital capacity declined during this 10 years. Students' nutritious status improved, but they still lack physical ex-
