目的 分析丽水市2016-2019年低出生体重发生情况及其影响因素,为减少低出生体重发生率制定干预措施提供依据。方法 回顾性分析丽水市妇幼保健院2016-2019年分娩的934例低出生体重儿发生的临床数据,采用多因素Logistic 回归分析低出生体重发生的危险因素。结果 2016-2019年妇幼保健院共分娩活产19 535例胎儿,其中低出生体重儿934例,发生率为4.78%;2016-2019年低出生体重儿发生率差异无统计学意义(χ2趋势= 0.019,P=0.891);多因素Logistic 回归显示, 早产(OR=46.283,95%CI:38.408～56.773)、双胎(OR=7.023,95%CI:5.347～9.223)、女婴(OR=1.549,95%CI:1.304～1.841)、妊娠高血压(OR=4.945,95%CI:3.262～7.498)、胎膜早破(OR=1.305,95%CI:1.053～1.618)、胎儿窘迫(OR=2.103,95%CI:1.515～2.919)、胎盘早剥(OR=1.651,95%CI:1.152～2.366)、农村户籍(OR=1.274,95%CI:1.014～1.601)是发生低出生体重的危险因素(P<0.05)。结论 丽水市低出生体重发生率低于全国平均水平,应注重加强农村户籍、妊娠合并高血压和双胎孕妇的围生期管理,避免早产、胎膜早破、胎盘早剥的发生,从而减少低出生体重的发生。
Abstract
Objective To investigate the occurrence of low birth weight in Lishui City from 2016 to 2019 and to analyze the influencing factors for low birth weight, in order to provide basis for reducing the occurrence of low birth weight. Methods Clinical data of 934 low birth weight infants born in Lishui Maternity and Child Health Hospital from 2016 to 2019 were retrospectively collected and analyzed.Multivariate Logistic regression was used to analyze the risk factors of low birth weight. Results From 2016 to 2019, Lishui Maternity and Child Health Hospital delivered 19 535 live births of fetuses, of whom 934(4.78%) were low birth weight infants.There was no significant difference in the incidence of low birth weight infants from 2016 to 2019 (χ2=0.019, P=0.891).Multivariate Logistic regression showed that preterm birth (OR=46.283, 95%CI:38.408-56.773), twins (OR=7.023,95%CI:5.347-9.223), female infants (OR=1.549, 95%CI: 1.304-1.841), pregnancy-induced hypertension (OR=4.945, 95%CI:3.262-7.498), premature rupture of membranes (OR=1.305, 95%CI:1.053-1.618), fetal distress (OR=2.103, 95%CI:1.515-2.919), placental abruption (OR=1.651,95%CI: 1.152-2.366),rural household registration (OR=1.274,95%CI:1.014-1.601) were risk factors for low birth weight(P＜0.05). Conclusions The incidence of low birth weight in Lishui City is lower than the national average, and attention should be paid to strengthening the perinatal management of pregnant women in rural areas, pregnancy with hypertension and twins to avoid preterm delivery, premature rupture of membranes and premature abruption of the placenta, thereby reducing the incidence of low birth weight.
