Unwanted pregnancies are considered as one of the most important public health risks. Regarding the importance of the unwanted pregnancy in the country and helping health policy-makers obtain more accurate information on this issue, this study aims to provide a systematic review and meta-analytical on the prevalence of unwanted pregnancies in Iran.
The present study was carried out using meta-analysis. Articles related to the topic were obtained through SID, Magiran, Scopus, PubMed, and ScienceDirect and Google Scholar databases from 2001 to 2017, Articles written based on cross-sectional studies were included in the study and other overviews, case-control, cohort, and interventional studies were excluded from the list of articles. Heterogeneity of studies was investigated using I index and data analysis was performed in Comprehensive Meta-Analysis software (Version 3).
In 23 articles, the prevalence of unwanted pregnancy in Iranian women was 27.9% (95%CI: 24-32.1%). The meta-regression analysis was used in two sample sizes and years of study. It was reported that as the sample size and Years increases, the prevalence of the unwanted pregnancy decrease, this difference was also statistically significant (P = 0.000).
Considering that the prevalence of unwanted pregnancy is high in Iran, it is necessary that health policy makers take effective measures to enhance the awareness of couples and public information about the risks of the unwanted pregnancy.
意外怀孕被认为是最重要的公共卫生风险之一。鉴于意外怀孕在该国的重要性，以及帮助卫生政策制定者获得有关此问题的更准确信息，本研究旨在对伊朗意外怀孕的流行率进行系统评价和荟萃分析。
本研究使用荟萃分析进行。通过 SID、Magiran、Scopus、PubMed 和 ScienceDirect 以及 Google Scholar 数据库，从 2001 年到 2017 年获得了与该主题相关的文章，纳入了基于横断面研究的文章，而将其他综述、病例对照、队列和干预性研究排除在文章列表之外。使用 I 指数调查研究的异质性，并在 Comprehensive Meta-Analysis 软件（版本 3）中进行数据分析。
在 23 篇文章中，伊朗女性意外怀孕的流行率为 27.9%（95%CI：24-32.1%）。对两个样本量和研究年限进行了荟萃回归分析。报告称，随着样本量和研究年限的增加，意外怀孕的流行率降低，这种差异也具有统计学意义（P=0.000）。
鉴于伊朗意外怀孕的流行率较高，卫生政策制定者有必要采取有效措施，提高夫妇对意外怀孕风险的认识，并加强公众对相关信息的了解。
