中国母婴健康相关队列研究的文献计量分析

目的  回顾分析母婴健康队列研究的应用趋势，展望未来发展方向。 方法  检索中国发表的中文及英文(简称“中英文”)母婴队列研究文献，对发表时间、科研单位、研究目标与随访调查等情况进行统计分析。 结果  自1991年以来，母婴健康队列研究的文献数量明显增加，中英文核心期刊群均已形成。中英文文献发表数量的年平均增长率分别为12.2%和23.2%，54.4%的中文文献与79.3%的英文文献为近5年发表。56.9%的中文文献发表在核心期刊，54.3%的英文文献发表在影响因子>3分的期刊。国内外期刊发表的文献均以病因研究为主，多为大样本研究，回归分析模型运用普遍。 结论  队列研究在我国母婴健康领域的应用逐渐增加，但研究者仍需加强对队列研究的认识，控制失访率、改善随访效果，运用Cox回归分析模型等统计分析方法，更加科学地运用队列研究解决实际问题。

A bibliometric analysis on cohort study of maternal and child health in China

Objective To retrospectively analyze the application trend of cohort study in the field of maternal and child health and to look forward to its future development trend. Methods Chinese and English papers reporting the cohort studies of maternal and child health conducted in the mainland of China were included. The literature management software was used to analyze the publication time, institution, type and objective of the studies and the follow-up performance. Statistical analysis was carried out by using SPSS 22.0. Results The number and quality of the papers reporting maternal and child health-related cohort studies increased significantly in the past 30 years and a core Chinese and English journal group of this field has been formed. The average annual growth rates of Chinese and English papers published were 12.2% and 23.2% respectively. About 54.4% of the Chinese papers and 79.3% of the English papers were published in the past five years with high quality. The number of Chinese papers published on Chinese core journals accounted for 56.9% while English papers published on SCI periodicals(IF>3) accounted for 54.3%. For the study objective, those published on the domestic and SCI journals mainly focused on etiologic research(90.8% and 91.3% respectively), being the most of which were large-scale studies. High-quality SCI papers were more interested in the studies of etiologic researches, and regression analysis was the common statistical method to be used. Conclusions The application of cohort study in the field of maternal and child health gradually increased in China. Large-scale study and regression analysis were conducted commonly. However, it is necessary to further improve the researchers’ understanding of cohort study, improve the follow-up quality, and increase the application of scientific evaluation methods, such as Cox regression analysis, for the better solving of practical problem.
