| Abstract | The school environment is crucial for the child’s health and
well-being. On the other hand, the data about the role of school’s
aerosol pollution on the etiology of chronic non-communicable diseases
remain scarce. This study aims to evaluate the level of indoor aerosol
pollution in primary schools and its relation to the incidence of
doctor’s diagnosed asthma among younger school-age children. The
cross-sectional study was carried out in 11 primary schools of Vilnius
during 1 year of education from autumn 2017 to spring 2018. Particle
number (PNC) and mass (PMC) concentrations in the size range of
0.3–10 µm were measured using an Optical Particle Sizer (OPS, TSI model
3330). The annual incidence of doctor’s diagnosed asthma in each school
was calculated retrospectively from the data of medical records. The
total number of 6–11 years old children who participated in the study
was 3638. The incidence of asthma per school ranged from 1.8 to 6.0%.
Mean indoor air pollution based on measurements in classrooms during the
lessons was calculated for each school. Levels of PNC and PMC in
schools ranged between 33.0 and 168.0 particles/cm3 and 1.7–6.8 µg/m3,
respectively. There was a statistically significant correlation between
the incidence of asthma and PNC as well as asthma and PMC in the
particle size range of 0.3–1 µm (r = 0.66, p = 0.028) and (r = 0.71, p = 0.017)
respectively. No significant correlation was found between asthma
incidence and indoor air pollution in the particle size range of 0.3–2.5
and 0.3–10 µm. Conclusion: We concluded that the number and mass concentrations of indoor air aerosol pollution in primary schools in the particle size range of 0.3–1 µm are primarily associated with the incidence of doctor’s diagnosed asthma among younger school-age children. What is Known: • Both indoor and outdoor aerosol pollution is associated with bronchial asthma in children. What is New: • The incidence of bronchial asthma among younger school age children is related to indoor air quality in primary schools. • Aerosol pollutants in the size range of 0.3–1 µm in contrast to larger size range particles can play major role in the etiology of bronchial asthma in children. |
