Insights
Socioeconomic factors, not nutritional status, are linked to intestinal parasite prevalence in children. Overcrowding and poor housing increase risk, while better sanitation and resources offer protection.
Area of Science:
- Public Health
- Infectious Diseases
- Pediatrics
Background:
- Intestinal parasites disproportionately affect vulnerable populations, necessitating effective management strategies in endemic regions.
- Understanding the interplay between environmental factors, socioeconomic status, and parasitic infections is critical for public health interventions.
Purpose of the Study:
- To investigate the association between intestinal parasites, socioeconomic characteristics, and anthropometric nutritional status in children.
- To identify risk and protective factors for intestinal parasite infections in a specific endemic area.
Main Methods:
- An observational, cross-sectional study involving 588 children aged 1-15 years in Tartagal, Argentina.
- Fecal analysis using sedimentation (Teleman), Kato-Katz, and Baerman methods for parasite detection.
- Standardized surveys for demographic/socioeconomic data and anthropometric measurements (height, weight, etc.).
Main Results:
- 55.4% of children had intestinal parasites, with Giardia lamblia and Hymenolepis nana being most common.
- Risk factors included age, overcrowding, and walking barefoot; protective factors included refrigerator ownership, animal corrals, and adequate water storage.
- Malnutrition due to excess weight affected 31.9% of participants; housing and public service access indicated high vulnerability.
Conclusions:
- A significant association exists between socioeconomic conditions and the risk of intestinal parasite presence.
- No correlation was found between anthropometric nutritional status and intestinal parasite infections in this cohort.
Introduction:
Intestinal parasites particularly affect vulnerable populations, making their management crucial in endemic areas.
Objective:
To evaluate the relationship between intestinal parasites, socioeconomic characteristics, and anthropometric nutritional status.
Methods:
This is an observational, cross-sectional study conducted on children aged 1 to 15 years in Tartagal, Argentina, for a year. Intestinal parasitic infections were determined through fecal analysis using sedimentation techniques (Teleman), Kato-Katz, and the Baerman method. Demographic and socioeconomic data were collected using a standardized survey. Height, weight, and mid-upper arm and head circumference were measured in the participants.
Results:
Of the 588 participants who provided fecal samples, 55.4% had intestinal parasites, with G. lamblia and H. nana being the most prevalent species. Additionally, 31.9% of participants were found to have malnutrition due to excess weight. Risk factors for intestinal parasite presence included age, overcrowding, and walking barefoot, while owning a refrigerator, having an animal corral, adequate water storage, and belonging to the Guaraní ethnic group were protective factors. High vulnerability areas were observed regarding housing conditions and access to public services.
Conclusions:
An association between socioeconomic conditions and the risk of intestinal parasite presence was observed. However, no association was found between anthropometric nutritional status and the presence of intestinal parasites.
