[Parasite intestinal infection and factors associated with coccidian infection in adults at public hospital in Lima, Peru].
To evaluate the frequency of intestinal parasites and risk factors associated with coccidian infection in patients cared for at a public hospital in Lima-Peru. A descriptive, cross-sectional study was conducted using reports of the parasitology laboratory. Patients included were >18 years, who gave at least one faecal sample for parasitologic evaluation. Logistic regression was used to calculate Odd Ratios (OR) and 95%) confidence intervals. 2.056 patients were included in the analysis, 55.2% of them were males and 334 (16.3%) were HIV positive. Overall, Blastocystis hominis was the most frequent parasite (35.4%). The multivariate model adjusted for sex shows that HIV infection (OR = 4.53; 95% CI: 3.03-6.77), being hospitalized (OR = 2.42; 95% CI: 1.06-5.52), and age > or = 40 years (OR = 0.57; 95% IC: 0.37-0.86) were associated with coccidian infection. Blastocystis hominis was the most frequent parasite in HIV positive and negative patients. Being hospitalized and HIV infection were risk factors for coccidian infection, but age > or = 40 years was a protective factor.DOI: /S0716-10182009000600008
