Intestinal Parasites Among the Elderly in Old Peoples Homes in Osun State, Southwest Nigeria

The elderly population represents a uniquely vulnerable group for intestinal parasitic infections due to age-related immunosenescence, comorbidities, and communal living arrangements. This descriptive cross-sectional study assessed the prevalence of intestinal parasites among elderly residents of registered old peoples homes in Osun State, Southwest Nigeria. Stool samples from 160 residents aged 60 years and above were examined using the direct wet preparation and formal-ether concentration techniques. A structured geriatric health questionnaire captured medication history, mobility limitations, and hygiene capability. Overall intestinal parasite prevalence was 44.4 percent. Entamoeba histolytica, Giardia lamblia, and hookworm were the most frequently encountered parasites. Residents with impaired mobility and those dependent on caregivers for personal hygiene had significantly higher infection rates. Comorbid diabetes and use of immunosuppressive medications were associated with heavier parasite burdens. The study recommends routine parasitological screening as part of the health assessment for elderly persons in care homes, combined with caregiver training in infection control and hygiene assistance for dependent residents in Southwest Nigeria.
