Objective To monitor and analyze the tendency of baby physical development in Haikou City. Methods To establish the system management data of 3000 newborns with normal birth in our hospital from June 1996 to December 2001, and to monitor the data for 1 year longitudinally, compared with the normal infant development in 1987 in this area. Results The weight, length and head circumference of infants in our city were all higher than those of normal infant development in 1987. Compared with the physical development values of children under 7 years of age in the suburbs of nine cities in China in 1995, the average value of physical development was lower than that of the nine cities (P <0.05-0.01), except the three-month-old male and female. Conclusion The fastest growing stage of infancy is the first critical stage of infant growth and development at 3 months and 3 months after birth, and the 12th month is the second critical stage of infant growth and development.
