The low level of psychiatric research in low- and middle-income (LAMI) countries has been identified as a cause for concern, particularly because the extent of the unmet need for psychiatric treatment in many LAMI countries is not known. The aim of this study was to establish if the worldwide increase in research publication during the last decade included an increase in publication about mental disorders from LAMI countries.
We searched PubMed for articles about mental disorder, depression and schizophrenia using the names of LAMI and high-income (HI) countries in the institutional affi liation address (AD) field published during two five-year periods: 1998-2002 and 2003-2007. We then examined the relationship between per capita publications about mental disorder and the independent variables of per capita gross domestic product purchasing power parity (GDP ppp), per capita psychiatric beds, per capita psychiatrists, total population and whether the country had a designated mental health budget.
The number of medical research publications per capita, and the number of publications about mental disorder from LAMI countries is low when compared to the rate from HI countries. However, the absolute number of publications from LAMI regions and the proportion of research publications about mental disorder, schizophrenia and depression increased significantly during the decade of the study. There were independent associations between GDP ppp and population size and the rate of publications about mental disorder in LAMI countries.
The overall increase in the number of publications about mental disorder in the last decade probably reflects an increase in psychiatric research in LAMI countries. The increase in rates of publication was greatest in middle-income countries with the largest populations.
中低收入（LAMI）国家的精神医学研究水平较低，这令人担忧，尤其是因为许多 LAMI 国家的精神科治疗需求未得到满足的程度尚不清楚。本研究旨在确定过去十年中全球研究出版物的增加是否包括 LAMI 国家发表的关于精神障碍的出版物的增加。
我们在 PubMed 中使用 LAMI 和高收入（HI）国家的机构附属地址（AD）字段中的名称搜索了关于精神障碍、抑郁症和精神分裂症的文章，搜索时间为两个五年期：1998-2002 年和 2003-2007 年。然后，我们研究了精神障碍人均出版物数量与人均国内生产总值购买力平价（GDP ppp）、人均精神病床位、人均精神科医生、总人口以及国家是否有指定的心理健康预算等独立变量之间的关系。
与 HI 国家相比，LAMI 国家的人均医学研究出版物数量和关于精神障碍的出版物数量都较低。然而，LAMI 地区的出版物绝对数量以及关于精神障碍、精神分裂症和抑郁症的研究出版物比例在研究期间显著增加。GDP ppp 和人口规模与 LAMI 国家关于精神障碍的出版物率之间存在独立关联。
过去十年中关于精神障碍的出版物数量总体增加，可能反映出 LAMI 国家精神医学研究的增加。在人口最多的中等收入国家中，出版物增长率最高。
