20.500.12556/RUL-168864 Identification of indoor air quality factors in Slovenian schools national cross-sectional study Poor indoor air quality (IAQ) in schools is associated with impacts on pupils’ health and learning performance. We aimed to identify the factors that affect IAQ in primary schools. The following objectives were set: (a) to develop a questionnaire to assess the prevalence of factors in primary schools, (b) to conduct content validity of the questionnaire, and (c) to assess the prevalence of factors that affect the IAQ in Slovenian primary schools. Based on the systematic literature review, we developed a new questionnaire to identify factors that affect the IAQ in primary schools and conducted its validation. The questionnaires were sent to all 454 Slovenian primary schools; the response rate was 78.19%. The results show that the most important outdoor factors were the school’s micro location and the distance from potential sources of pollution, particularly traffic. Among the indoor factors, we did not detect a pronounced dominating factor. Our study shows that the spatial location of schools is key to addressing the problem of IAQ in schools. air quality factors primary school questionnaire cross-sectional study kakovost zraka osnovne šole anketa presečna študija true false true Angleški jezik Slovenski jezik Članek v reviji 2025-04-30 11:26:34 2025-04-30 11:26:35 2025-05-01 03:57:14 0000-00-00 00:00:00 2023 0 0 16 str. iss. 13 Vol. 11 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 614 2227-9717 10.3390/pr11030841 146393347 Galicic,_Medved_..._-_Identification.pdf Galicic,_Medved_..._-_Identification.pdf 1 C0D916626E6526D369793B46AD43E3D0 e12a54495e47ab0f6e144f1f74421805c9aa9ab03e79f00da87d009a9c022ee2 81b3d1a2-25a5-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209933 https://www.mdpi.com/2227-9717/11/3/841 1 0dbbfac8-25a4-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209932 Fakulteta za strojništvo Medicinska fakulteta 0 0 0
