[Giardia lamblia infestation at child day care centers. Nutritional impact in infested children]

Area of Science:

• Pediatric infectious diseases
• Nutritional epidemiology
• Public health microbiology

Context:

• Giardia lamblia (G. lamblia) is a common intestinal parasite affecting young children, particularly in daycare settings.
• The nutritional and clinical impact of G. lamblia infections in pediatric populations requires further elucidation.
• This study investigated G. lamblia cyst excretion and its association with growth parameters and gastrointestinal symptoms in a cohort of daycare attendees.

Purpose:

• To assess the prevalence of Giardia lamblia cyst excretion in children attending a day care center.
• To evaluate the nutritional status (weight, height, skinfold thickness) of children with and without G. lamblia infection.
• To compare the frequency of gastrointestinal symptoms between infected and non-infected children.

Summary:

• Seventy-five children (aged 6-65 months) were surveyed for G. lamblia cyst excretion, with 23% found to be positive.
• No significant differences in weight, height, arm skinfold thickness, or gastrointestinal symptoms were observed between children excreting G. lamblia cysts and those without.
• A subset of infected children remained positive at a 6-month follow-up.

Impact:

• The findings suggest that Giardia lamblia infestation may have minimal to no adverse nutritional impact on young children in a daycare setting.
• These results highlight the need for larger studies to confirm the limited nutritional consequences of G. lamblia in this demographic.
• This research contributes to understanding the clinical significance of asymptomatic or mildly symptomatic G. lamblia infections in children.
