Latin American medical journals have a low impact factor. Higher quality articles originated in Latin American countries are published in North American or European journals.
To analyze the impact factor of Latin-American journals according to the language of publication.
The data base of periodic journals of the Thomson ISI (Journal of Citation Report) in the year 2004 was used for the analysis. Four countries with more than one journal in the data base of the Thomson ISI were included (Argentina, Brazil, Chile and Mexico).
Few Latin-American journals are included in the Thomson ISI data base. The mean impact factor was 0.76 (0.23-3.2) for eight Mexican journals, 0.66 (0.10-2.1) for eight Chilean journals, 0.39 (0.06-0.7) for five Argentinian journals and 0.41 (0.09-1.1) for 16 Brazilian journals. The mean impact factor for 11 journals written in English was 0.74 (0.12-2.1), 0.53 (0.09-3.2) for 18 bilingual journals and 0.28 (0.06-0.56) for eight journals written in native language. The differences between countries and languages were not statistically significant.
The journal impact factor was similar in the four countries studied. A non-significant higher impact factor was observed in Latin-American journals published in English.
拉丁美洲医学期刊的影响因子较低。源自拉丁美洲国家的高质量文章发表在北美或欧洲期刊上。
根据出版语言分析拉丁美洲期刊的影响因子。
分析使用了汤姆森ISI（期刊引证报告）2004年的期刊数据库。纳入了在汤姆森ISI数据库中有不止一种期刊的四个国家（阿根廷、巴西、智利和墨西哥）。
汤姆森ISI数据库中收录的拉丁美洲期刊很少。八本墨西哥期刊的平均影响因子为0.76（0.23 - 3.2），八本智利期刊为0.66（0.10 - 2.1），五本阿根廷期刊为0.39（0.06 - 0.7），十六本巴西期刊为0.41（0.09 - 1.1）。十一本英文期刊的平均影响因子为0.74（0.12 - 2.1），十八本双语期刊为0.53（0.09 - 3.2），八本母语期刊为0.28（0.06 - 0.56）。国家和语言之间的差异无统计学意义。
在所研究的四个国家中，期刊影响因子相似。英文出版的拉丁美洲期刊的影响因子略高，但无统计学意义。
