Perbedaan Perubahan Persentase Berat Badan Menurut Tinggi Badan pada Anak Sekolah Dasar yang Mengalami Reinfeksi dengan yang Tidak Mengalami Re-Infeksi Soil Transmitted Helminths di Kabupaten Mandailing Natal, Provinsi Sumatera Utara

Abstract

Background: Soil transmitted helminths (STH) infections are nematode infections that included in the Neglected Tropical Diseases (NTDs) and commonly found in developing countries. STH infection and malnutrition are overlapping circles. Implementation of mass drug administration (MDA) has been shown to reduce intensity and severity of infection and improve children's health, although it cannot prevent re-infection. There are previous studies that reviewed nutritional status of children who experienced STH reinfection. The study stated no relationship between STH re-infection and incidence of malnutrition in the 3-month monitoring. Objective: To prove the difference in BW/BH percentage change in elementary school children who experienced compared to who didn’t experienced STH re-infection. Methods: Analytic study with cross sectional design that conducted in elementary schools at Mandailing Natal Regency, North Sumatra Province from December 2021 to April 2022. Using secondary data through anthropometric tracing to observe differences in body weight/body height percentage change based on 2000 CDC curve. Samples are all elementary school children who have been monitored for 8 months from March to November 2019. The main result of this study is percentage of BW/BH at 0, 4, and 8-months in children with and without STH re-infection. Result: From 428 children, all samples were divided into 2 groups, such intervention for who experienced and control for who didn’t experience STH re-infection. There was a statistically significant difference in first assessment, a decrease in BW/BH percentage which +0.27% in control group, while an increase in intervention group, which +0.35% (95%CI -1.25 - -0.02; p=0.049). There was no statistically significant difference between both groups in BW/BH percentage during 2nd (p=0.69) and at the end monitoring (p=0.98). Conclusion: There was a significant differences in BW/BH percentage changes in children who experience compared to those without re-infection in 4 month evaluation, but didn’t significant in 8 month interval.
