School Health Research Library
We have curated a library of peer-reviewed scientific studies from around the world published since 2016, focusing on the school built environment and occupant health and performance. This research builds on the 2017 Schools for Health: Foundations for Student Success report released by Harvard T.H. Chan School of Public Health that synthesizes foundational research about school indoor environmental quality impacts on students and staff.
To help translate this research into action in schools, we have compiled School Health Research Highlights to help school staff and leaders access key findings and actionable strategies on priority topics.

Factors Influencing Classroom Exposures to Fine Particles, Black Carbon, and Nitrogen Dioxide in Inner-City Schools and Their Implications for Indoor Air Quality
Mathaios, Vasileios N.
LASSO identified 10, 10, and 11 significant factors (lowercase italic p less than 0.05p<0.05) that were associated with indoor fine particulate matterPM2.5, BC, and nitrogen dioxideNO2 exposures, respectively. The overall variability explained by…

Survey and Measurements of Indoor Environmental Quality in Urban/Rural Schools Located in Romania
Catalina, Tiberiu
Optimal thermal comfort is not met during the cold season in any of the schools under investigation. The old rural schools were found to be the worst performing buildings compared to urban schools where due to recent investments in refurbishment…

The Adverse Associations of Classrooms’ Indoor Air Quality and Thermal Comfort Conditions on Students’ Illness Related Absenteeism between Heating and Non-Heating Seasons—A Pilot Study
Deng, Shihan
During non-heating season, a 3% increase of IRA was estimated with 1,000,000-counts/L increase of particles that had a diameter less than 2.5 μm (PN2.5); during the heating season, a 3% increase of IRA were expected with 100 ppm increase of room…

Airborne fungal and bacterial microbiome in classrooms of elementary schools during the COVID-19 pandemic period: Effects of school disinfection and other environmental factors
Yang, Jun I. L.
lassrooms disinfected with spray ≤1 week before sampling had lower bacterial DNA concentration (3116 DNA copies/m3) than those >1 week (5003 copies/m3) (p-values = 0.06). The bacterial DNA copy number concentration increased with temperature and…

Investigation of bacterial and fungal communities in indoor and outdoor air of elementary school classrooms by 16S rRNA gene and ITS region sequencing
Lee, Bong Gu
The bacterial community was richer in outdoor air than classroom air, whereas fungal diversity was similar indoors and outdoors. Bacteria such as Enhydrobacter, Micrococcus, and Staphylococcus that are generally found in human skin, mucous membrane…

Impact of Environmental Factors on the Prevalence Changes of Allergic Diseases in Elementary School Students in Ulsan, Korea: A Longitudinal Study
Lee, Jiho
Generalized estimating equations (GEE) were used to investigate the impact of environmental factors on the change in the prevalence of allergic diseases. The survey revealed that an increased risk of allergic rhinitis was associated with exposure to…

Ultrafine and Fine Particulate Matter Inside andOutside of Mechanically Ventilated Buildings
Miller, Shelly
The ratio of indoor-to-outdoor (I/O) PM was weakly but positively correlated with the amount of ventilation provided to the indoor environment, did not vary much with particle size (ranged between 0.48 and 0.63 for the entire size range), and was…

Children environmental exposure to particulate matter and polycyclic aromatic hydrocarbons and biomonitoring in school environments: A review on indoor and outdoor exposure levels, major sources and health impacts
Oliverira, M
Strong evidences demonstrated associations between environmental exposure to PM and PAHs with several health outcomes, including increased risk of asthma, pulmonary infections, skin diseases, and allergies. Nevertheless, there is a scientific gap…

Combined effects of ventilation rates and indoor temperatures on cognitive performance of female higher education students in a hot climate
Ahmed, R
Potential benefits were found on speed and accuracy of tasks of cognitive performance when indoor temperature was set between 20 and 23ºC and at CO2 levels of 600 ppm compared to higher temperatures and poorer ventilation rates and that both…

Comments to “Assessment of formaldehyde levels in relation to respiratory and allergic symptoms in children from Alba County schools, Romania” by Neamtiu et al. (2019)
Wolkoff, P
In summary, the authors present an unbalanced and
inconsistent interpretation of their data and with unsubstantiated focus on FA; the authors disregard a more
appropriate explanation for adverse respiratory effects in
the…
