目的 探讨应用医院产科记录资料进行职业有害因素对妊娠经过和妊娠结局影响研究的实用价值。方法 设计专用调查表对北京市 8所医院产科病房住院分娩的 12 2 2 4名初产妇进行个案调查。根据产科记录及于产妇出院前由医护人员进行的问卷调查 ,收集产妇的一般情况 ;本次妊娠时的妊娠并发症、妊娠结局及分娩并发症 ;以及孕期接触职业有害因素情况等资料。从中抽取孕期接触职业有害因素的产例 (接触组 )以及孕期未接触任何职业有害因素的产例 (对照组 )分别组成队列 ,分析不良妊娠经过和结局与孕期接触职业有害因素有无关联。对潜在的混杂因素 (年龄、孕期吸烟或饮酒、自然流产史等 )采用Logistic回归分析。结果 孕期职业接触噪声者 12 72例 ,孕期职业接触全身振动者 5 99例 ,孕期职业接触有毒化学物质者 10 0 6例 ,对照组 92 6 0例。接噪组妊娠高血压综合征(妊高征 )、早产、低出生体重、宫内发育迟缓、产后出血的发病率 (分别为 10 .2 %、4.9%、3.8%、2 .5 %、4.7% )增高 ,与对照组 (分别为 8.1%、3.4%、2 .6 %、1.5 %、3.4% )比较 ,差异有显著性 (P <0 .0 5或P<0 .0 1) ;接振组妊高征、早产、低出生体重、宫内发育迟缓、产后出血的发病率 (分别为 11.9%、5 .8%、4.0 %、2 .5 %、7.2 % )增高 ,接毒组妊?
Objective To explore the practical value of using occupational records of hospitals to study the influence of occupational harmful factors on the course of pregnancy and the outcome of pregnancy. A questionnaire of method design was used to carry out a case investigation on 12,224 primipara born in obstetrics wards of 8 hospitals in Beijing. According to maternity records and maternal discharge prior to medical staff conducted a survey to collect the general situation of maternal; pregnancy pregnancy complications, pregnancy outcomes and childbirth complications; and occupational exposure to occupational hazards and other information. The cases (contact group) and the non-occupational hazardous factors (control group) during pregnancy were drawn into the cohort to make an analysis of the association between adverse pregnancy outcomes and occupational exposure to occupational harmful factors during pregnancy. Logistic regression analysis of potential confounding factors (age, smoking or drinking during pregnancy, history of spontaneous abortion, etc.) Results There were 12 72 cases of occupational exposure to noise during pregnancy, 579 cases of occupational vibration during pregnancy, 106 cases of occupational exposure to toxic chemicals during pregnancy, and 92 60 cases of control group. The incidence of gestational hypertension (PIH), premature birth, low birth weight, intrauterine growth retardation and postpartum hemorrhage were significantly higher in the control group (10.2%, 4.9%, 3.8%, 2.5%, 4.7 %) Were significantly higher than those in the control group (8.1%, 3.4%, 2.6%, 1.5% and 3.4%, respectively) The incidence of PIH, premature delivery, low birth weight, intrauterine growth retardation and postpartum hemorrhage (11.9%, 5.8%, 4.0%, 2.5%, 7.2% ?
