BackgroundDaily levels of ambient air pollution and pollen may affect lung function but have rarely been studied together. We investigated short-term exposure to pollen and air pollution in relation to lung function in school-age children from a French population-based birth cohort.MethodsThis study included 1063 children from the PARIS (Pollution and Asthma Risk: an Infant Study) cohort whose lung function and FeNO measurements were performed at age 8 years old. Exposure data were collected up to 4 days before testing. We estimated daily total pollen concentration, daily allergenic risk indices for nine pollen taxa, as well as daily concentrations of three air pollutants (particulate matter less than 10 µm (PM10), nitrogen dioxide (NO2), ozone (O3)). Children with similar pollen and air pollution exposure were grouped using multidimensional longitudinal cluster analysis. Associations between clusters of pollen and air pollution exposure and respiratory indices (FEV1, FVC, FeNO) were studied using multivariable linear and logistic regression models adjusted for potential confounders.ResultsFour clusters of exposure were identified: no pollen and low air pollution (Cluster 1), grass pollen (Cluster 2), PM10 (Cluster 3) and birch/plane-tree pollen with high total pollen count (Cluster 4). Compared with children in Cluster 1, children in Cluster 2 had significantly lower FEV1 and FVC levels, and children from Cluster 3 had higher FeNO levels. For FEV1 and FVC, the associations appeared stronger in children with current asthma. Additional analysis suggested a joint effect of grass pollen and air pollution on lung function.ConclusionDaily ambient chemical and biological air quality could adversely influence lung function in children.

Cross Sectional Survey

Background: Major questions remain regarding the agestratified trends of allergic diseases and asthma in Korea.Purpose: To identify the estimated recent prevalence and 10- year trends in asthma, allergic rhinitis, and atopic dermatitis among the Korean population from 2008 to 2017.Methods: This nationwide cross-sectional survey (Korean National Health and Nutrition Examination Survey) over 10 years (2008–2017) examined representative samples of the Korean population (n=85,006) including 2,131 infants, 4,352 preschool children, 12,919 school-age children, 44,200 adults, and 21,404 elderly adults.Results: In the 2016 to 2017 population, the estimated prevalence of asthma was 0.9% in infants, 2.3% in preschool children, 4.1% in school-age children, 2.3% in adults, and 4.1% in the elderly. The estimated prevalence of allergic rhinitis was 9.0%, 20.2%, 27.6%, 17.1%, and 6.9%, respectively. The estimated prevalence of atopic dermatitis was 5.9%, 11.3%, 14.6%, 3.9%, and 1.6%, respectively. Ten-year trends revealed a significant decrease in asthma prevalence in infants, preschool children, and the elderly. and in atopic dermatitis prevalence in infants and preschool children (<i>P</i><0.05 for all trends). Furthermore, 10-year trends demonstrated a significant increase in allergic rhinitis prevalence in school-age children, adults, and the elderly, and in atopic dermatitis prevalence in school-age children and the elderly (<i>P</i><0.05 for all trends).Conclusion: These results improve our understanding of the age-stratified epidemiology of allergic diseases in Korea and suggest the need for the development of tailored and precise strategies to prevent allergic diseases in different age groups.

AbstractThe number of people with excess weight increases every year. Overweight and obesity in childhood can cause several chronic diseases in adulthood. Children with excess body mass develop more morphological and functional changes, including pulmonary functions. One of the common methods to assess lung function is spirometry. This method is a challenge in assessing lung function for pre-school age children. The aim of this study was to evaluate the correlation between lung vital capacity and body mass index for the pre-school children aged 3–7 years in Rīga. In total 995 pre-school children were included in the study. An informative consent and questionnaire about the development of each individual child was filled in by parents. Several measurements were performed, including height, body mass, and lung vital capacity. This is the first study in Latvia where several morphologic and somatometric measurements were determined in children of pre-school age. There was a positive and statistically significant correlation between lung vital capacity and body height, mass, and chest circumference. The correlation between lung vital capacity and body mass index was not statistically significant. The main results do not differ from the results of similar studies in other countries. The obtained results will help to create a standard of morphological and somatometric parameters in pre-school aged children in Rīga region.
