To examine changes in subject contents and study designs of research articles published in the Journal of Adolescent Health since its inception.
A retrospective review of all research articles was conducted from selected years, ranging from 1980 through 1998. The study sample was composed of the following: original articles, case reports, brief scientific reports, international articles, fellowship forum, and health briefs.
A total of 582 articles were evaluated. The total percentage of medical topics in research articles published in the Journal decreased from 61% in 1980-1981 to 38% in 1997-1998 (p <.01). This finding was in contrast to topics related to psychosocial issues, which increased from 23% to 50% (p <.01) over the same period. This change was largely accounted for by studies focusing on high-risk behavior. Retrospective designs, including case reports/series and chart reviews, decreased from 25% of all research articles in 1980-1981 to 9% in 1997-1998 (p <.01). The percentage of observational studies, i.e., those using cross-sectional and longitudinal designs, increased from 62% to 79% over the same period (p <.01). No changes were observed in the percentage of experimental designs, never exceeding >5% of total study designs. Finally, over the 20 years, professional background and academic departments of first authors of research broadened, with increasing contributions from nonphysicians and from non-pediatric disciplines such as psychology, public health, and nutrition.
A shift in subject content of research articles from medical to psychosocial topics was observed over the past 2 decades. A shift in research designs from retrospective to cross-sectional and longitudinal was observed over the same period. The pool of authors has diversified.
探讨《青少年健康杂志》自创刊以来发表的研究文章的主题内容和研究设计的变化。
对1980年至1998年选定年份的所有研究文章进行回顾性综述。研究样本包括以下几类：原创文章、病例报告、简短科学报告、国际文章、奖学金论坛和健康简报。
共评估了582篇文章。该杂志发表的研究文章中，医学主题的总百分比从1980 - 1981年的61%降至1997 - 1998年的38%（p <.01）。这一发现与心理社会问题相关主题形成对比，同期该类主题从23%增至50%（p <.01）。这种变化主要是由关注高危行为的研究导致的。回顾性设计，包括病例报告/系列和图表回顾，从1980 - 1981年占所有研究文章的25%降至1997 - 1998年的9%（p <.01）。同期，观察性研究（即采用横断面和纵向设计的研究）的百分比从62%增至79%（p <.01）。实验设计的百分比未观察到变化，从未超过总研究设计的5%。最后，在这20年里，研究第一作者的专业背景和学术部门有所拓宽，非医生以及心理学、公共卫生和营养等非儿科学科的贡献增加。
在过去20年中，观察到研究文章的主题内容从医学向心理社会主题转变。同期，研究设计从回顾性向横断面和纵向转变。作者群体也变得更加多样化。
