title: [Hymenolepis nana infection: associated factors with this parasitism in a health area of Southern Spain].
abstract: Hymenolepis nana is the most common tapeworm in humans; prevalence rates of 0.1%-58% have been reported. The aim of this study was to determine the prevalence in a health area of Southern Spain and identify the demographic variables potentially associated with increased rates of hymenolepiasis in this area. A retrospective study was performed with patients, who had H. nana eggs in fecal samples during january 2000 to december 2013. Parasitological diagnosis relied on microscopic detection in concentrated stool samples. During the study period, 73.660 stool samples were analyzed. H. nana eggs were observed in 158 patients (31 female) with a mean age of 18,9 years. The prevalence during the study period was 0,21% and 61% of the infected patients had more than one intestinal parasite. In conclusion, the prevalence of parasitism by H. nana in our population was higher than the national average and higher in adults than in children due to the characteristics of our population.
