To determine the frequency and the main methodological characteristics of the epidemiological designs used in the research studies published in the journal Atencion Primaria between 1984 and 1990.
A descriptive study.
Included are all the articles presenting data produced by the authors themselves in the context of a research study and published in the sections of original articles, special contributions or clinical notes in the issues of the journal Atencion Primaria between 1984 and 1990.
A data-gathering questionnaire was used, whose concordance was previously assessed blindly by two observers. There were 324 articles included. Of these, 93% were descriptive studies, out of which 27% were prevalence studies. Of these prevalence studies, 15.7% were conducted among the population as a whole. A questionnaire, which had been previously validated in 47.7% of cases, was used in 13.5% of the studies. Experimental research accounted for 21 studies (6.5%), of which 85% had an explicit control group.
Only a small proportion are analytical studies. The majority of descriptive studies are carried out among the population attending for treatment.

描述性研究。
纳入1984年至1990年期间发表在《初级保健》杂志的原创文章、特别贡献或临床笔记板块中，作者本人在研究背景下产生数据的所有文章。
使用了一份数据收集问卷，之前由两名观察者进行了盲法一致性评估。共纳入324篇文章。其中，93%为描述性研究，其中27%为患病率研究。在这些患病率研究中，15.7%是针对全体人群开展的。13.5%的研究使用了一份之前已在47.7%的病例中得到验证的问卷。实验性研究有21项（6.5%），其中85%有明确的对照组。
只有一小部分是分析性研究。大多数描述性研究是在接受治疗的人群中进行的。
