摘要
目的维尔维克指数(VI)主要反映人体的胸廓发育、体型和营养状况。该研究旨在调查胎龄27~42周新生儿出生时的VI值,制定其百分位曲线。方法 2013年4月至2015年9月采用横断面时间段整群抽样实况调查方法,在深圳两家医院完成了16865例胎龄27~42周单胎新生儿体重、身长、胸围现场测量,用以计算VI值,并制定不同胎龄新生儿的VI百分位曲线。结果获得了胎龄27~42周单胎新生儿(男、女、性别混合)三分组的VI均数,并制定了其3rd^97th百分位曲线。胎龄27周者VI的50th曲线值最低,随着胎龄增加,VI的50th曲线值不断增大,胎龄42周者50th曲线值最大。各胎龄组女性VI的50th百分位曲线数值均略高于男性。结论新生儿出生时VI值伴随胎龄增加而增大。女性新生儿出生时胸廓发育、体型、营养状况可能略好于男性。该研究制定的胎龄27~42周单胎新生儿(男、女、性别混合)三分组的VI百分位曲线可为深圳新生儿出生时胸廓发育、体型和营养状况的评估提供参考。
Objective Ververck index（VI） reflects thoracic development, body type, and nutritional status. This study aimed to investigate the VI of singleton neonates with a gestational age（GA） of 27-42 weeks at birth, and to establish percentile curves of VI of the neonates. Methods Cross-sectional cluster sampling was performed between April 2013 and September 2015. Body weight, body length, and chest circumference were measured for 16 865 singleton neonates with a GA of 27-42 weeks in two hospitals in Shenzhen, China. VI was calculated and the percentile curves of VI were plotted for the neonates. Results Mean VIs were obtained for singleton neonates with a gestational age of 27-42 weeks（in three groups of male, female, and both sexes）, and related 3rd-97 th percentile curves were plotted. As for the 50 th percentile curve, the singleton neonates with a GA of 27 weeks had the lowest 50th percentile value of VI, which gradually increased with the increase in GA. The singleton neonates with a GA of 42 weeks had the highest 50 th percentile value of VI. Girls had a slightly higher 50 th percentile value of VI than boys in all GA groups. Conclusions VI of neonates increases with the increase in GA. Female neonates may have a slightly better thoracic development, body type, and nutritional status than male neonates at birth. The percentile curves of VI plotted for singleton neonates with a GA of 27-42 weeks（in three groups of male, female, and both sexes） can provide a basis for evaluating thoracic development, body type, and nutritional status of neonates at birth in Shenzhen, China.
