低出生体重儿体格与智能发育的调查研究

对上海市徐汇区１９８３年出生的，出生体重＜２５００ｇ的小儿共１３２例，进行了连续３年生长发育纵向随访。并随机选择４９例足月正常儿为对照组。两组小儿定期随访体格发育３项指标，并用Ｇｅｓｅｌｌ发育诊断法进行发育评价。结果显示低体重儿组在３岁前体格生长指标明显低于对照组。从增长速度看，体重的增长略低于对照组，身高、头围则不明显。智能方面总发育商及多数能区发育商在３岁前均低于对照组，差别均有显著意义。从落后能区看，以动作能区最为突出。因此应加强孕产期保健，降低低出生体重儿的发生率，对低出生体重儿应进行育儿指导和早期训练，以促进其体格和智力的正常发育。

A longitudinal study of growth and development of low birth weight infants

In order to investigate the growth and development of low birth weight infant(LBWI) ,132 low birth weight infants (BW<2500g) born in 1983 living in Xi Hui district were followed up from birth to three years. And 49 full-term infants with normal birth weight were selected as controls. The weight, length, and head circumference of infants of two groups were measured periodically. Their development abilities were assessed by using Gesell Development Diagosis. Results showed the weight, length, and head circumference of LBWI were obviously less than that of the controls. The developmental quotient (DQ) of LBWI were lower than that of controls,particularly in gross motor field,Therefore , it is important to reduce the rate of IBWI and to give scientific guidance on child care and early training for promoting growth and development of infants.
