Abstract

Background: Gestation at birth is associated with short and long-term outcomes. This study used high quality, national, administrative data to examine trends in gestation at birth in Scotland.

Methods: This observational study used maternity hospital discharge records for 2005 to 2019 to determine trends in the percentage of live births that were preterm (<37 weeks gestation), term (37-41 weeks), and post-term (≥42 weeks), overall and by maternal age and deprivation category. Preterm births were further examined by category of preterm birth (moderate to late [32-36 weeks]; very [28-31 weeks]; extremely [<28 weeks] preterm), and onset of labour (spontaneous; provider-initiated). Singleton and multiple births were examined separately. Aggregate logistic regression was used to estimate the annual change in the odds of a birth being in a specified gestational category.

Results: The percentage of singleton births in Scotland that were preterm decreased from 2005 (6.5%, 3,361/51,665) to 2010 (5.8%, 3268/56344), then increased to 2019 (7.2%, 3,408/47,507). The percentage of singleton births that were spontaneous moderate to late, very, and extremely preterm all increased between 2010 and 2019. The percentage of singleton births that were provider-initiated moderate to late preterm also increased between 2010 and 2019, however provider-initiated very or extremely preterm birth decreased. The percentage of singleton births that were preterm increased over time across all maternal age and deprivation categories, with increases greatest in groups at highest baseline risk. The percentage of singleton births that were post-term increased from 2005 to 2009, then decreased to 2019.

Conclusions: There has been an increase in spontaneous preterm birth from 2010 to 2019, which is not fully explained by changes in maternal age or deprivation. Further research to examine the contribution of other, preventable, risk factors is warranted. Trends in provider-initiated preterm birth, and post-term birth, are likely to reflect changing clinical practice.

2005 年至 2019 年苏格兰活产胎龄趋势：一项基于人口的研究。

背景：出生时的妊娠与短期和长期结果有关。本研究使用高质量的全国性行政数据来研究苏格兰出生时妊娠的趋势：这项观察性研究使用了 2005 年至 2019 年的产科医院出院记录，以确定早产活产婴儿所占百分比的趋势（结果：苏格兰单胎早产婴儿所占百分比从 2005 年的 0.5%下降到 2019 年的 0.5%）：苏格兰早产的单胎比例从2005年（6.5%，3,361/51,665）下降到2010年（5.8%，3268/56344），然后上升到2019年（7.2%，3,408/47,507）。在 2010 年至 2019 年期间，自发中晚期早产、非常早产和极早产的单胎比例均有所上升。在 2010 年至 2019 年期间，由医疗服务提供者发起的中晚期早产的单胎比例也有所上升，但由医疗服务提供者发起的非常早产或极早产的比例有所下降。在所有孕产妇年龄和贫困类别中，单胎早产的比例随着时间的推移而增加，在基线风险最高的群体中增幅最大。2005 年至 2009 年，单胎早产的比例有所上升，随后降至 2019 年：从 2010 年到 2019 年，自发性早产有所增加，但这并不能完全归因于产妇年龄或贫困程度的变化。有必要进一步研究其他可预防风险因素的作用。医疗机构引发的早产和过期产的趋势很可能反映了临床实践的变化。

期刊介绍： Wellcome Open Research publishes scholarly articles reporting any basic scientific, translational and clinical research that has been funded (or co-funded) by Wellcome. Each publication must have at least one author who has been, or still is, a recipient of a Wellcome grant. Articles must be original (not duplications). All research, including clinical trials, systematic reviews, software tools, method articles, and many others, is welcome and will be published irrespective of the perceived level of interest or novelty; confirmatory and negative results, as well as null studies are all suitable. See the full list of article types here. All articles are published using a fully transparent, author-driven model: the authors are solely responsible for the content of their article. Invited peer review takes place openly after publication, and the authors play a crucial role in ensuring that the article is peer-reviewed by independent experts in a timely manner. Articles that pass peer review will be indexed in PubMed and elsewhere. Wellcome Open Research is an Open Research platform: all articles are published open access; the publishing and peer-review processes are fully transparent; and authors are asked to include detailed descriptions of methods and to provide full and easy access to source data underlying the results to improve reproducibility.
