Air pollution and respiratory allergic diseases in schoolchildren.

Nicolussi FH, Santos AP, André SC, Veiga TB, Takayanagui AM - Rev Saude Publica (2014)

Bottom Line: Study on the prevalence of allergic respiratory diseases in schoolchildren between six and seven years old, associated with indicators of air pollution.There was a positive correlation between monthly frequency of rhinitis and concentration of pollutants, and negative with relative air humidity.Even with levels of air pollutants below that allowed by law, the prevalence of asthma, rhinitis and associated symptoms tended to be higher in the central region school, where there is heavy vehicular traffic.

ABSTRACT
Study on the prevalence of allergic respiratory diseases in schoolchildren between six and seven years old, associated with indicators of air pollution. A questionnaire based on the International Study of Asthma and Allergies in Childhood was administered to parents of students from public schools, located in urban areas with differing vehicle flows. There was a positive correlation between monthly frequency of rhinitis and concentration of pollutants, and negative with relative air humidity. Even with levels of air pollutants below that allowed by law, the prevalence of asthma, rhinitis and associated symptoms tended to be higher in the central region school, where there is heavy vehicular traffic.

f01: Analysis of the main components for environmental variables and symptoms ofallergic rhinitis in six- and seven-year old pupils in public schools inRibeirao Preto, SP, Southeastern Brazil, between November 2009 and October2010.

Mentions: Symptoms of allergic rhinitis (sneezing, itching, blocked nose, not caused by a cold)were more frequent in the third trimester of 2010, coinciding with increased levelsof MP10 and NO2, and with the driest period of the year.Analysis of the data showed a strong negative correlation between symptoms ofrhinitis and RH% (r = -0.91) and a positive correlation with MP10 andNO2 (r = 0.89 and 0.88, respectively) (Figure).
