目的:探讨早产及其相关危险因素。方法:纵向随访研究,通过面对面问卷调查,收集妊娠妇女背景资料、孕期个人行为习惯、社会环境因素、妊娠期健康状况等相关信息,随访至分娩,收集妊娠结局资料。数据采用多因素Logistic回归分析方法。结果:711例调查对象中,早产117例(16.46%),发生率较既往报道高。未发现妊娠期个人行为习惯与早产的关系,但年龄增长、工作噪音和胎膜早破与早产明显有关,OR分别为1.43(95%CI:1.05~1.94)、3.38(95%C I:1.21~9.39)、2.14(95%C I:1.19~3.83)。结论:面对早产的高发生率,不应忽略社会环境的潜在影响。对外来务工的妊娠妇女,孕期保健时应常规询问职业状况等因素,以及时发现不利影响,给予适当帮助和指导。
Objective: To explore the preterm birth and its related risk factors. Methods: According to the longitudinal follow-up study, face-to-face questionnaires were used to collect the pregnant women background information, personal behavioral habits during pregnancy, social environmental factors, pregnancy health status and other related information. Data using multivariate Logistic regression analysis. Results: In 711 cases, 117 cases (16.46%) were premature, the incidence was higher than previous reports. No relationship was found between gestational behavior and premature labor, but age, working noise and premature rupture of membranes were significantly associated with preterm labor (OR = 1.43, 95% CI: 1.05-1.94, 3.38, 95% CI: 9.39), 2.14 (95% CI: 1.19-3.83). Conclusion: In the face of the high prevalence of preterm birth, the potential impact of social environment should not be overlooked. Pregnant women migrant workers during pregnancy should be routinely asked about occupational health and other factors, and timely detection of adverse effects, to give appropriate help and guidance.
