INTRODUCTION the act to search can be defined as the search of knowledge concerning one determined reality from the use of systematic and formal procedures. It is through the accomplishment of research that we have witnessed the sprouting of discoveries and the construction of knowledge that enclose until the aspects most trivial of the experience human being and, each time more, this activity if it shows essential for the reinforcement of any disciplines. In the area of the nursing this does not reveal different, being several the authors who have emphasized repetidamente that to generate knowledge by means of research it is basic condition for its characterization as a science. Of the historical point of view, the research started to be part of the daily one of the Brazilian nursing only recently. In fact, the first works carried through for nurses on the basis of date of the years of 1950 the scientific method. In the years that if had followed, an increment in this associated activity can be folloied, mainly, to the sprouting of Courses of After-Graduation in the Country, having as sustentculo the studies carried through for pupils and professors in related courses. Discoursing on the evolution of the research in nursing, Saupe demonstrates that since its beginning until the current days it had an expressive increase in relation to the scientific production of the nurses and tells that the changes had not only occurred in relation to the amount of published works, but also as for the types of research carried through and used methodologies.
Exactly recognizing the advances gotten in relation to the research in the present time, we understand that, to continue progressing, the necessary nursing to be constantly involved in a process of evaluation and reevaluation of the produced knowledge. That is necessary a time that, if the nursing desires to be contributing for the scientific development and technological as other areas of knowledge, produced knowing it must condizer with the social demands and have considerable informative value. In this manner the subjects that have excited the interest of researchers of some areas, in national and international scope, present the referring questions to the world of the work and its repercussions in the relative health of the individuals and, in particular way, aspects to the health of the worker. Considering such estimated, it is our interest to investigate if such questions have stimulated the nurses to develop research and to analyze as the scientific production of the nursing has focused the interrelaes between the labor activity and the relative process health-illness the workers and, in last analysis, to verify which the contribution of this production in the direction to characterize the health of the worker as important field of elaboration of knowledge. In this manner, the objective of the study is to analyze the research concerning the thematic Health of the Worker, published in periodic of nursing in the period of 2007-2011.
