Abstract

MELGAREJO-TOUCHET, Nancy. Intestinal parasitosis in adolescents from 10 to 19 years old, who inhabit the area of influence of the USF Santa María. Asuncion, Paraguay. Rev. Inst. Med. Trop. [online]. 2019, vol.14, n.1, pp.29-39. ISSN 1996-3696.  https://doi.org/10.18004/imt/201914129-39.

Introduction:

Intestinal parasitosis (PI) is an endemic regional public health problem, and our country is not exempt from it. The objective of this research was to determine the prevalence of PI in adolescents aged 10 to 19 years, under surveillance of the USF Santa María, Asunción, Paraguay, from August to November 2013; The Methodology consisted of a descriptive and transversal study in 46 young people, with surveys in which the socio-sanitary and educational conditions of the population were evaluated, and laboratorial analyzes of blood and faecal samples. In the blood samples the hemoglobin concentration (g / dl) was evaluated, and in the fecal samples (3-day serials) the search for intestinal parasites was evaluated. For the analysis of the data obtained, the epi info program was used.

Results:

It was found that 43% of the subjects were parasitized, with a prevalence of 56.3% in the male sex and 36.7% in the female sex. It has not been possible to establish an association between IP and the variables sex and age. Assessing the different risk factors, such as the elimination of garbage and excreta, and drinking water consumption, it has not been possible to establish an association with IP (p> 0.05).

The fecal samples analyzed contained 60% of a single type of parasite and 40% were polyparasitized (2 species). The predominant species was Blastocystis hominis (40%), followed by Giardia lamblia (15%) and Endolimax nana (5%). Polyparasitosis was given by Blastocystis hominis with Entamoeba coli (15%), followed by Blastocystis hominis with Giardia lamblia (10%), Blastocystis hominis with Entamoeba hystolitica / dispar (5%), Blastocystis hominis with Endolinax nana (5%) and Ascaris lumbricoides with Entamoeba hystolitica / dispar (5%).

It has not been possible to establish an association of the IP with the nutritional status evaluated with the parameters of Body Mass Index (weight and height), and blood hemoglobin concentration (p> 0.05).

Conclusion:

The high prevalence of PI found as a result in this study, coinciding with other studies conducted in previous years in our country, shows that this problem in public health is still postponed.
