Objective： To investigate the relative factors and trends in neonatal birth weight in Xinxiang city in 10 years. Methods： In some a Maternity and Child Health Care Hospital of Xinxiang city, 5 025 cases of full - term neonates born from 2001 to 2011 were ana- lyzed, the relations between neonatal weight and different genders and year of birth, parents living area, parity, maternal age, mode of deliv- ery, etc. Results： Except that in a few years, the average wieght of male and female neonates under investigation was not significantly differ- ent in most years. There was an upward trend. The average weight of male neonates was （3 451 ±433） g, and that of female neonates was （3 328±434） g. The incidence of macrosomia in males was （ 11.5% ）, higher than that in females （7. 6% ）. The average weight of the males in cities was （3 500 ± 436） g, that of the females was （3 361 ± 429） g. The average weight of the males in rural areas was （3 413 ± 427 ） g, that of the females was （3 299 ± 437 ） g. There was significantly difference between cities and rural areas. Second - birth males weighed （3 469 ±437） g, females weighed （3 369 ± 441 ） g, they were greater than those of first -birth males and females （P 〈0.05 ）. The average weight of male neonates in group of puerpera＇s age at 20 -24 was （3 385 ±399） g, female neomates was （3 261 ±427） g. In group of puerpera＇s age at 25 - 29, the average weight of male neonates was （ 3 451 ± 433 ） g, female was （ 3 336 ± 419 ） g. In group of pu- erpera＇s age at 30 -34, the average weight of male neonates was （3 500 ±442） g, female was （3 393 ±467） g respectively. There were statistical differences among different ages groups （P 〈 0.05 ） . Conclusion： The average birth weight of the noenates in Xinxiang city in re- cent 10 years is stable and has a slightly increasing trend. The average birth weight of the male noenates is greater than that of females. The incidence of macrosomia in males is higher than that of females. The average birth weight of urban neonates is greater than that of rural ones. With the increasing of maternity age and parity, the neonate birth wieght is increased.
