Abstract
In several industrialized countries, there has been a report of a decrease in the proportion of male births. The current study is designed to perform a systematic review and present a comprehensive summary of current epidemiological evidence of an association between exposure to the mentioned pollutants and sex ratio. The present systematic review was executed according to the PRISMA protocol. A comprehensive online search was performed in PubMed Medline, Scopus, Web of Science, Embase databases, Google Scholar, and the World Health Organization databases from 2000 to September 2023. After searching all databases, 20 articles were included in this systematic review. Regarding the studied pollutants found that exposure to increased PM10, PM2.5, and Nitrogen dioxide (NO2) levels was significantly associated with the sex ratio. Both maternal Benzophenone (BP)-2 and paternal BP-2 were significantly associated with an excess of female births. Finally, it must be said that the effect of some environmental pollutants on the sex ratio is undeniable. However, the sex ratio is the result of multiple factors that interact simultaneously during pregnancy. Additional research is required to examine the mechanisms responsible for the change in sex ratio.
在几个工业化国家,有报告说,男婴出生的比例有所下降。目前的研究旨在进行系统审查,并对暴露于上述污染物与性别比之间存在关联的现有流行病学证据进行全面总结。本系统评价是根据PRISMA方案进行的。从2000年到2023年9月,在PubMed Medline、Scopus、Web of Science、Embase数据库、谷歌Scholar和世界卫生组织数据库中进行了全面的在线搜索。在检索所有数据库后,本系统综述纳入了20篇文章。关于所研究的污染物,发现暴露于增加的PM10、PM2.5和二氧化氮(NO2)水平与性别比例显著相关。母亲的二苯甲酮(BP)-2和父亲的BP-2都与过量的女婴有关。最后,必须说一些环境污染物对性别比的影响是不可否认的。然而,性别比例是怀孕期间多种因素同时相互作用的结果。需要进一步的研究来检查造成性别比例变化的机制。
期刊介绍:
Reviews on Environmental Health (REVEH) is an international peer-reviewed journal that aims to fill the need for publication of review articles on hot topics in the field of environmental health. Reviews on Environmental Health aims to be an inspiring forum for scientists, environmentalists, physicians, engineers, and students who are concerned with aspects of human health, including quality of life, that are determined by physiological and psychosociological interactions between man and physical, chemical, biological, and social factors in the environment.
Reviews on Environmental Health is an important niche served by no other journal, that’s being a site where thoughtful reviews can be published on a variety of subjects related to both health and environment. One challenge is to bridge the research on environmental causes of disease with the clinical practice of medicine. Reviews on Environmental Health is a source of integrated information on environment and health subjects that will be of value to the broad scientific community, whether students, junior and senior professionals, or clinicians.
