目的:探讨低出生体重的发生情况及其影响因素,为减少低出生体重的发生提供可靠的理论依据。方法:采用病例对照研究方法对某三甲医院产科172例低出生体重儿及1 368例正常体重新生儿的出生体重及父母双方的流行病学资料进行调查,探讨低出生体重的危险因素。结果:多因素Logistic回归分析显示:孕周<37周(OR=36.397)、该次妊娠患有妊娠期高血压疾病(OR=6.085)、初次妊娠孕期增重<10 kg(OR=1.841)是低出生体重的危险因素,产前检查≥8次(OR=0.030)是保护因素。结论:制定有效政策,做好孕期保健宣传,增强孕期保健意识,预防和控制妊娠期高血压疾病的发生发展是降低低出生体重发生的重要环节。
Objective: To investigate the incidence of low birth weight and its influencing factors, and provide a reliable theoretical basis for reducing the incidence of low birth weight. Methods: A case-control study was conducted to investigate the birth weight and the epidemiological data of 172 parents with low birth weight and 1 368 normal weight in Obstetrics and Gynecology in a top three hospital to investigate the risk factors of low birth weight. Results: Multivariate Logistic regression analysis showed that the gestational age was less than 37 weeks (OR = 36.397), with gestational hypertension (OR = 6.085) and weight gain <10 kg Low birth weight risk factors, prenatal care ≥ 8 times (OR = 0.030) are protective factors. Conclusion: It is an important step to reduce the incidence of low birth weight by formulating effective policies, doing a good job of propagating the health care during pregnancy, increasing the awareness of health care during pregnancy, and preventing and controlling the occurrence and development of hypertensive disorder during pregnancy.
