The potential impact of employment on maternal health, particularly in relation to gestational hypertension and pre-eclampsia, has been subject to research. However, there is limited evidence on associations between shift work and long working hours on the incidence of these conditions.
To evaluate potential associations between maternal shift work and long working hours during pregnancy and gestational hypertension or pre-eclampsia.
Multistage stratified systematic sampling was used to recruit 24 200 post-partum women from the Taiwan national birth registration database in 2005. Subjects underwent home interview 6 months after their deliveries by structured questionnaire to obtain characteristics of maternal employment and potential confounders. Diagnosis of gestational hypertension and pre-eclampsia was obtained from the birth registration.
There was no association between employment status and gestational hypertension or pre-eclampsia. Also, no significant association between gestational hypertension or pre-eclampsia and maternal shift work or long working hours during pregnancy was found in all or primiparous women.
There was no convincing evidence that maternal shift work or long working hours had a higher risk of gestational hypertension or pre-eclampsia. However, further research is warranted to confirm these negative findings.
就业对产妇健康的潜在影响，特别是与妊娠高血压和子痫前期的关系，已经有研究。然而，关于轮班工作和长时间工作与这些疾病发病率之间的关联，证据有限。
评估妊娠期间产妇轮班工作和长时间工作与妊娠高血压或子痫前期的潜在关联。
2005 年，采用多阶段分层系统抽样法，从台湾国家出生登记数据库中招募了 24200 名产后妇女。通过结构化问卷对她们进行了产后 6 个月的家庭访谈，以获得产妇就业和潜在混杂因素的特征。妊娠高血压和子痫前期的诊断来自出生登记。
就业状况与妊娠高血压或子痫前期之间无关联。此外，在所有或初产妇中，妊娠高血压或子痫前期与产妇轮班工作或怀孕期间长时间工作之间也没有显著关联。
没有令人信服的证据表明产妇轮班工作或长时间工作会增加妊娠高血压或子痫前期的风险。然而，需要进一步的研究来证实这些阴性结果。
