As welfare societies, Scandinavian countries share characteristics of equality related to healthcare access, gender, and social services. However, cultural and lifestyle variations create country-specific health differences. This meta-analysis assessed the prevalence of preterm birth (PTB) and its categories in Scandinavian countries.
A systematic search in key databases of literature published between 1990 and 2021 identified studies of the prevalence of PTB and its categories. Following the use of the Freeman-Tukey double arcsine transformation, a meta-analysis of weighted data was performed using the random-effects model and meta-prop method.
We identified 109 observational studies that involved 86,420,188 live births. The overall pooled prevalence (PP) of PTB was 5.3% (PP = 5.3%, 95% confidence interval [CI] 5.1%, 5.5%). The highest prevalence was in Norway (PP = 6.2%, 95% CI 5.3%, 7.0%), followed by Sweden (PP = 5.3%, 95% CI 5.1%, 5.4%), Denmark (PP = 5.2%, 95% CI 4.9%, 5.3%), and Iceland (PP = 5.0%, 95% CI 4.4%, 5.7%). Finland had the lowest PTB rate (PP = 4.9%, 95% CI 4.7%, 5.1%).
The overall PP of PTB was 5.3%, with small variations among countries (4.9%-6.2%). The highest and lowest PPs of PTB were in Norway and Finland, respectively.
作为福利社会，斯堪的纳维亚国家在医疗保健可及性、性别和社会服务方面具有平等的特征。然而，文化和生活方式的差异造成了各国特有的健康差异。本荟萃分析评估了斯堪的纳维亚国家早产及其分类的患病率。
在1990年至2021年期间发表的文献的关键数据库中进行系统检索，以确定早产及其分类患病率的研究。在使用弗里曼-图基双反正弦变换之后，采用随机效应模型和元比例法对加权数据进行荟萃分析。
我们确定了109项观察性研究，涉及86420188例活产。早产的总体合并患病率（PP）为5.3%（PP = 5.3%，95%置信区间[CI] 5.1%，5.5%）。患病率最高的是挪威（PP = 6.2%，95% CI 5.3%，7.0%），其次是瑞典（PP = 5.3%，95% CI 5.1%，5.4%）、丹麦（PP = 5.2%，95% CI 4.9%，5.3%）和冰岛（PP = 5.0%，95% CI 4.4%，5.7%）。芬兰的早产率最低（PP = 4.9%，95% CI 4.7%，5.1%）。
早产的总体PP为5.3%，各国之间差异较小（4.9%-6.2%）。早产的最高和最低PP分别出现在挪威和芬兰。
