obstetric transition

  • 文章类型: Journal Article
    背景:本文揭示了过去二十年索马里孕产妇死亡率(MMR)和产科转型的趋势。
    方法:这是一项描述性研究,比较了2006年多指标类集调查和2020年索马里健康和人口调查的汇总次级数据,以显示过渡情况。
    结果:与两项调查相比,观察到每10万活产的MMR从1044减少到692%。
    结论:索马里已从产科过渡途径谱的I期过渡到II期,人们乐观地认为,卫生系统的不断加强正在取得成果。
    BACKGROUND: This paper sheds light on the trends of the maternal mortality ratio (MMR) and obstetric transition in Somalia over the last two decades.
    METHODS: This is a descriptive study comparing aggregate secondary data from the 2006 Multiple Indicator Cluster Survey and the 2020 Somali Health and Demographic Survey to show the transition.
    RESULTS: A 44% reduction of the MMR from 1044 to 692 per 100 000 live births was observed comparing the two surveys.
    CONCLUSIONS: Somalia has moved from stage I to stage II of the obstetric transition pathway spectrum and there is optimism that the ongoing strengthening of the health system is paying off.

    To evaluate whether pregestational obesity is associated with the risk of caesarean section in pregnant women living in a country in an advanced stage of the obstetric transition.
    Retrospective cohort study. Data were collected from prenatal and hospital records. Pregestational obesity was defined as: body mass index, [weight(k)/height (m2)] ≥30, and caesarean sections were categorized as elective, emergency, or non-emergency/medically necessary. Biodemographic and sociodemographic characteristics, obstetric and perinatal pathologies, and maternal anthropometric variables were assessed. Chi-square and t-tests were used to compare qualitative and quantitative variables, respectively. Simple and adjusted generalized linear models were used to evaluate the association between pregestational obesity and caesarean delivery. Finally, population attributable risk was calculated. Data analysis was performed using STATA.v.14.0.
    2309 pregnant women with a singleton pregnancy who gave birth at a public hospital in the Metropolitan Region of Santiago, Chile in 2015.
    The prevalence of pregestational obesity was 21.4%, and the incidence of caesarean deliveries was 34.8% (33% of which corresponded to elective, 46% to emergency, and 21% to non-emergency/medically necessary caesarean deliveries). Pregestational obesity increased the risk of caesarean delivery (aRR = 1.46; 95%CI. [1.19-1.79] as well as the risk of elective (aRR = 1.74; 95%CI. [1.23-2.45]) and emergency caesarean delivery (aRR = 1.44; 95%CI. [1.03-2.00]). The population attributable risk of pregestational obesity for caesarean section was 32%.
    Given the significant association between pregestational obesity and caesarean delivery, it is necessary to develop strategies to decrease obesity among women of childbearing age in order to decrease obstetric intervention.

    本文研究了可变报告和编码实践对苏格兰城乡孕产妇死亡率测量的影响,1861-1901年,使用记录的死亡原因和分娩后六周内死亡的妇女。此设置提供数据(n=604孕产妇死亡),以比较按死亡原因确定的孕产妇死亡率与通过记录链接确定的孕产妇死亡率,并将城市和农村环境与不同的认证实践进行对比。我们发现,漏报是最重要的间接原因,在传染病负荷高的地方,间接原因占孕产妇死亡率的比例很高。然而,即使死因报告看起来很准确,区分间接和直接孕产妇死亡率也可能存在问题.矛盾的是,在医生常规证明死亡的城市地区,孕产妇死亡的漏报率较高,我们认为,在医疗供应和报告死亡有显著差异的地方,孕产妇死亡率的差异可能反映了认证实践的真实差异。因此,更好的保健服务可能给人的印象是产妇死亡率低于实际水平。最后,我们对孕产妇死亡率统计数据的解释以及对产科过渡概念的影响进行了思考。
    This paper examines the effect of variable reporting and coding practices on the measurement of maternal mortality in urban and rural Scotland, 1861-1901, using recorded causes of death and women who died within six weeks of childbirth. This setting provides data (n = 604 maternal deaths) to compare maternal mortality identified by cause of death with maternal mortality identified by record linkage and to contrast urban and rural settings with different certification practices. We find that underreporting was most significant for indirect causes, and that indirect causes accounted for a high proportion of maternal mortality where the infectious disease load was high. However, distinguishing between indirect and direct maternal mortality can be problematic even where cause of death reporting appears accurate. Paradoxically, underreporting of maternal deaths was higher in urban areas where deaths were routinely certified by doctors, and we argue that where there are significant differences in medical provision and reported deaths, differences in maternal mortality may reflect certification practices as much as true differences. Better health services might therefore give the impression that maternal mortality was lower than it actually was. We end with reflections on the interpretation of maternal mortality statistics and implications for the concept of the obstetric transition.
