Intestinal parasites represent a serious public health problem, in both rural and urban areas, affecting mainly pediatric population. As described above, an analytical study of prevalence was conducted to determine the frequency of intestinal parasites, nutritional status and associated risk factors in preschool ¨Jacinto Lara¨. The sample was not random, conformed by 191 preschool children. It was used interview as data collection instrument,determining frequency of epidemiological factors, anthropometric parameters were obtained to determine nutritional status and it was performed an analysis of stool samples through direct techniques of saline physiological and Lugol′s solution, concentrates Kato, Quensel and Graham method. It was found 41,4% of preschool children infected by intestinal parasites, predominating age was 6 years 46,9%, prevailed males 48.9%.Main protozoa found were Blastocystis hominis 53, 1%, Giardia lamblia 29, 1% and helminthes Enterobius vermicularis 17, 7% and Ascaris lumbricoides 5%. Predominance of symptoms such as expulsion of parasites 55% and paleness 51, 5%. Nutritional status of preschool children infected by intestinal parasites was normal 42,4%, the epidemiological factor where prevailed parasites was inadequate disposal of excreta 57,1% and the absence of antiparasitic treatment in the last 6 months 47,3%. In conclusion the study found nosigni cant association between the risk factors studied and the frequency of intestinal parasites, nevertheless, the high frequency of preschool children infected by intestinal parasites compromise to analyze other epidemiological elements in future researches.
