目的：构建中国婴儿出生体重、顶臀长和头围的孕周特异性标准。
设计：一项前瞻性横断面人群研究。
方法：在香港10家公立医院和2家私立医院的产科，使用标准设备对孕周在24 - 42周的新生儿的出生体重、顶臀长和头围进行前瞻性测量。这些测量结果用于构建这些变量的孕周特异性标准。采用最大惩罚似然法的LMS方法进行模型拟合。将结果与1982年至1986年在同一地区出生的一组婴儿的结果进行比较。
结果：1998年10月至2000年9月，共测量了10032名婴儿，占同期香港总分娩数的9.6%。2000年10月至2001年6月，又招募了307名孕周小于等于35周的婴儿。这三个变量在每个孕周均呈正态分布。分别为男婴和女婴构建了每个变量的孕周特异性参考标准。与1982 - 1986年队列相比，出生体重有显著的长期增长趋势。顶臀长和头围的增长趋势较小，但也很显著。
结论：这些生长标准将为华裔新生儿的护理提供有用的参考。这些标准，尤其是出生体重标准，应定期更新。
Objective: To construct gestation specific standards of birth weight, crown-heel length, and head circumference of Chinese infants.Design: A prospective cross sectional population study.Methods: The birth weight, crown-heel length, and head circumference were prospectively measured using standard equipment in newborns delivered at 24-42 weeks gestation in the maternity units of 10 public hospitals and two private hospitals in Hong Kong. The findings were used to construct gestation specific standards of these variables. The LMS method using maximum penalised likelihood was used to perform model fitting. The results were compared with those obtained from a cohort of infants born in the same locality between 1982 and 1986.Results: From October 1998 to September 2000, a total of 10 032 infants were measured, representing 9.6% of the total deliveries in Hong Kong during that period. An extra 307 infants with gestation less than or equal to 35 weeks were recruited from October 2000 to June 2001. Each of the three variables showed a normal distribution at each gestational week. Gestation specific reference standards for each variable were constructed for male and female infants separately. Comparison with the 1982-1986 cohort showed a significant secular trend to increased birth weight. The trend was small, but significant, for crown-heel length and head circumference.Conclusion: These growth standards will provide useful references for the care of newborns of ethnic Chinese origin. These standards, especially that for birth weight, should be updated regularly.
