不同季节与早产儿/低出生体重儿发生规律的相关性研究

The related research between different seasons and the premature/low birth weight babies occurrence regularity

目的:探讨早产儿/低出生体重儿与不同季节的相关性。方法:收集2008年5月～2010年5月在江西省妇幼保健院出生早产儿/低出生体重儿临床资料,分析各月份及各气候季型中早产儿分布、死亡情况及与气候的关系。结果:研究期间出生的早产儿/低出生体重儿1 638例,占该医院同期出生总人数的7.72%(1 638/21 229)。其中秋冬季节早产儿/低出生体重儿占8.16%高于春夏季节7.21%(P<0.01);秋冬季节早产儿/低出生体重儿病死率2.92‰和春夏季节2.31‰差异无统计学意义(P>0.05)。结论:秋冬季节早产儿/低出生体重儿的发生显著高于春夏季节,表明气候与早产儿/低出生体重儿的发生相关。

Objective： To investigate the correlation between the preterm/low birth weight babies and different season in Jiangxi province maternal and child care hospital. Methods： The deaths and the distribution of the premature/low birth weight babies in May 2008 to May 2010 were collected, four seasons in the Gregorian calendar, March, April, May months for spring, June, July and August for the summer, September, October, November months for autumn, with the December, January, February months for winter were divided and the correlation between the preterm/low birth weight babies and the climate in the different months and the climate season types were analyzed. Results： Premature/low birth weight babies which borned in our hospital were 1 638 cases in the study period, accounting for the total number born during the same period of the constituent ratio was 7. 72% （ 1 638/21 229）. Constituent ratio of the premature/low birth weight babies in autumn and winter season （8. 16% ） were higher than those of spring and summer season （7.21%） （P 〈0. O1 ） . There was no statistical difference in the mortality in premature/low birth weight babies between autumn and winter season （2. 92 ‰） and spring and summer season （2. 31‰） . Conclusion： The premature/low birth weight babies happened in the spring and summer are significantly higher than that in spring and summer season, which indicates that the climate and the occurrence of premature/low birth weight babies is related.
