Methods: Data on growth and development of students from 7 to 17 years old collected in 1997 in Chongqing were analyzed and were compared with those from the 1990 Chonqing survey and the 1995 national survey. Results: Adolescent growth spurt age was from 11 to 15 years(males) and from 9 to 14 years(females), urban students had better levels of growth and development than rural students. Two across phenomena'were observed in morphological parameters between males and females, but male students were always better than female students in functional parameters. During the Past 7 years, morphological parameters of Chongqing students tended to rise, but they were lower than the results from the 1995 national survey.Functional development levels of Chongqing stuents in 1997 were lower than in 1990, and they were also lower than the national levels in 1995. Conclusions: Secular growth changes were found in morphological parametersamong Chongqing primary and secondary school students, however, their functional development was poor.
