Abstract (English)

This study evaluated the prevalence of intestinal protozoan parasite infections and their association with the nutritional status of school-aged children (6 to 12 years old) in Barangay 711, Malate, Manila. Eleven (11) stool samples were analyzed using the Formalin-Ether Concentration Technique (FECT), and anthropometric measurements were obtained to determine Body Mass Index (BMI) and height-for-age classifications. No intestinal protozoan parasites were detected, yielding a prevalence rate of 0%. It should be noted that the analysis focused specifically on protozoan parasites, and while the method used may detect helminths, the identification and reporting in this study were limited to protozoa. Despite the absence of infection, nutritional variations were evident: 45.0% of participants were underweight, 18.0% were overweight, and 9.1% were stunted, suggesting that nutritional disparities within the cohort cannot be attributed to intestinal parasitic protozoan infections and are more likely influenced by other factors, including dietary quality, socioeconomic conditions, and lifestyle practices. Interpretation of prevalence is limited by the small sample size.

Abstract (Filipino)

Layunin ng pananaliksik na ito na tukuyin ang pagkalaganap ng parasitikong protozoa sa bituka at ang kaugnayan nito sa katayuang nutrisyonal ng mga batang may edad 6 hanggang 12 sa Barangay 711, Malate, Maynila. Ginamit ang Formalin-Ether Concentration Technique (FECT) para suriin ang labing-isang (11) sampol ng dumi; kinuha naman ang timbang at taas ng mga bata para sa kanilang Body Mass Index (BMI) at height-for-age classification. Ang pagsusuri na ito ay nakatuon lamang sa mga parasitong protozoa, at bagama’t maaaring makakita ng mga helminth gamit ang FECT, ang pagkilala at pag-uulat sa pag-aaral na ito ay limitado lamang sa mga protozoa. Bagaman nakapagtala ng 0% prevalence rate o kawalan ng impeksyon sa mga parasitikong protozoa, nakita sa pagsusuri na may pagkakaiba-iba sa kanilang katayuang nutrisyonal: 45.0% ang underweight, 18.0% ang overweight, at 9.1% ang stunted. Nagpapahiwatig ito na ang suliraning nutrisyonal ay hindi bunsod ng parasitikong impeksyon, kundi maaaring dulot ng ibang salik gaya ng diyeta at pamumuhay. Gayunpaman, binibigyang-diin na limitado ang interpretasyong ito dahil sa liit ng bilang ng sampol.
