Hubungan Kepadatan Tungau Debu Rumah dengan Kejadian Rinitis Alergi berdasarkan Score for Allergic Rhinitis (SFAR) pada Mahasiswa Kedokteran Fakultas Kedokteran USU Angkatan 2022 Penghuni Indekos

Abstract

Introduction. Allergic rhinitis (AR) is a global health problem often caused by House Dust Mite (HDM) allergens. Student boarding house environments, with potential for poor hygiene and ventilation, can increase the risk of HDM exposure and affect health and academic performance. Objective. This study aimed to analyze the relationship between HDM density in boarding house rooms and the incidence of allergic rhinitis based on the Score for Allergic Rhinitis (SFAR) among 2022 students of the Faculty of Medicine, USU. Methods. This was an observational analytical study with a cross-sectional design. Samples were taken using the total sampling technique from 100 2022 FK USU students living in boarding houses. HDM density was measured from room dust samples by microscopic examination, and the incidence of AR was assessed using the SFAR questionnaire. Data were analyzed using the Spearman correlation test. Results and Discussion. HDM were found in 63 rooms (63%), with a dominance of Dermatophagoides sp. (57%). The majority (93.6%) of the HDM density was in the low category. A total of 52% of respondents (n=52) were categorized as positive for allergic rhinitis (SFAR ≥7). The majority of rooms (82%) had non-optimal humidity (<60%RH), which is suspected to suppress the HDM population. Conclusion. There was no statistically significant relationship between HDM density in boarding house rooms and the SFAR score (p=0.084).
