ABSTRACT

The aim of this study was to detect the presence of hymenolepis in a sample of 150 schoolchildren between 6 and 14 years of age and establish the relationship between the infection and (i) their nutritional state and (ii) availability of basic services in the child’s dwelling.
Materials and Methods. The consent of the parents was obtained. The coprological specimens were analyzed by the zinc sulphate method at 1: 180. A questionnaire was completed to discover the services available in their dwellings. The children were weighed and measured to calculate their BMI (Body Mass Index).
Results. Thirty five children (23.3%) were infected with Hymenolepis. Thirty four (22.6%) presented H. Nana, one (0.7%) H. diminuta. The association between H. nana and school grade was significant (p › 0.027). The Odds Ratio (OR) of having H. nana and being undernourished was 1.4 (a 60% probability). Having H. nana and lacking basic services showed an OR of 2. Having H. nana together with I. Buestchlii and being underweight was significant (p‹ 0.035). Other findings: 112 children presented parasites, sixty nine (74.7%) presented multiparasitism. School grade showed a significant association with Entamoeba histolytic (p‹ 0.006) and Escherichia coli (p‹ 0.014).
Conclusions. The prevalence of H. nana was high. The correlation between school grade and the disease was very significant. Enteroparasites (E. Histolytica, E. coli, I. buestchlii) associated with H. nana affected the BMI. The underweight children indicated nutrition problems. The lack of basic services, together with makeshift dwellings, favours infections. All these factors predispose children for deficient development and high morbidity-mortality.
