Effects of particulate air pollution and ozone on lung function in non-asthmatic children.
Information on the long-term effects of different air pollutant levels on lung function is relatively lacking in Asia and still inconclusive in the world. Age differential effects of air pollution are not known. ⋯ In children aged 6-15 years, sub-chronic exposure to ambient PM2.5 and ozone leads to reduced lung capacity, whereas acute exposure to ozone decreases mid-expiratory flow. In children aged 6-10 years, additional airway obstructive patterns in lung function may be associated with PM2.5 exposure.

Exposure to visible mould or dampness at home and sleep problems in children: Results from the LISAplus study.
Exposure to mould or dampness at home has been associated with adverse respiratory effects in all age groups. This exposure has also been related to insomnia in adults. We aimed to investigate the association between exposure to visible mould or dampness at home and sleep problems in children. ⋯ Our data suggests that visible mould or dampness at home might negatively influence sleep in children. The influence of allergic rhinoconjunctivitis on this association needs to be investigated in future studies.

Relationship between exposure to fine particulates and ozone and reduced lung function in children.
A limited number of studies have reported an association between long-term exposure to ambient air pollutants and lung function growth among children, with inconclusive results. ⋯ The study provides evidence that long-term exposure to PM2.5 and O3 may have a detrimental effect on the development of lung function in children. The estimated deficits were generally larger in boys, compared to girls.

Association of short-term exposure to ground-level ozone and respiratory outpatient clinic visits in a rural location - Sublette County, Wyoming, 2008-2011.
Short-term exposure to ground-level ozone has been linked to adverse respiratory and other health effects; previous studies typically have focused on summer ground-level ozone in urban areas. During 2008-2011, Sublette County, Wyoming (population: ~10,000 persons), experienced periods of elevated ground-level ozone concentrations during the winter. This study sought to evaluate the association of daily ground-level ozone concentrations and health clinic visits for respiratory disease in this rural county. ⋯ The results demonstrate an association of increasing ground-level ozone with an increase in clinic visits for adverse respiratory-related effects in the following day (lag day 1) in Sublette County; the magnitude was strongest during the winter months; this association during the winter months in a rural location warrants further investigation.
