流动人口中早产相关因素分析

目的总结佛山地区流动性人口孕妇早产的相关因素，以期为流动人口早产的预防和治疗提供依据。方法通过问卷调查方式采集5474例流动人口相关资料孕妇的基本情况，根据一般人口特征、妇产科和疾病相关方面进行分析。并采用多因素回归分析早产的独立危险因素。结果本组发生早产215例，发生率3.93%。年龄<25岁和>35岁、大学及以上学历者孕妇早产发生率较高；孕产次≥2次、人工流产≥2次、胎膜早破和多胞胎的孕妇发生早产的几率明显升高，孕妇合并子宫肌瘤或子宫畸形、阴道炎、瘢痕子宫等疾病时早产的发生几率明显升高，差异有统计学意义（P<0.05）。多因素回归性分析显示，妊娠次数（95%CI：1.45～4.96），阴道炎（95%CI：1.39～4.22）及胎膜早破（95%CI：2.01～7.69）是流动人口发生早产的独立危险因素（P<0.05）。结论佛山地区流动性人口孕妇早产与妊娠次数、阴道炎和胎膜早破等密切相关，建议产前检查项目中将阴道分泌物检验列为常规，并对有孕期阴道炎者采取积极的预防和治疗措施。

Objective To summarize the relevant factors in Foshan mobility of the population of preterm labor in pregnant women, in order to provide a basis for prevention and treatment of the floating population of preterm labor. Methods Basic information of 5 474 cases of pregnant women migrants relevant information through questionnaires manner were collected, according to the general demographic characteristics, disease-related aspects of obstetrics and gynecology and analyzed. Independent risk factors of preterm birth was analyzed by using multivariate regression analysis.Results There were 215cases of preterm delivery in the group, the incidence was 3.93%. Aged <25 years and >35 years old, higher university or higher, and the incidence of preterm birth in pregnant women; motherhood ≥2 times, abortion ≥2 times the odds of multiple births and premature rupture of membranes preterm birth in pregnant women significantly increased consolidation of pregnant women have genital surgery, with ovarian cancer or uterine fibroids, vaginitis, when the disease was significantly higher probability of occurrence of preterm uterine scar, etc., the difference was statistically significant (P<0.05). Multivariate regression analysis showed that the number of pregnancies (95% CI:1.45-4.96), vaginitis (95% CI:1.39-4.22) and premature rupture of membranes (95% CI:2.01-7.69) is a floating population of preterm delivery independent risk factors (P<0.05).Conclusion Premature birth of the population of pregnant women in Foshan is closely related to the number of pregnancies preterm birth in pregnant women, vaginitis, and premature rupture of membranes. It is recommended in the vaginal secretions as a routine prenatal test project, and there are those who take active vaginitis pregnancy prevention and treatment measures.
