Effect of Indoor Air pollution Related to Traffic and Fuel Gas Using for Cooking on Respiratory Diseases in Children and Teenagers in Urban Area of Shanghai / 环境与健康杂志

ABSTRACT

Objective To explore the indoor air pollution level related to traffic and fuel gas using for cooking and to assess its effect on the respiratory disease and symptoms in children and teenagers. Methods Based on a cross-sectional survey in 6 551 children and teenagers in the urban area of Shanghai in 2007, 197 children were randomly selected in stratified districts and the level of CO, NO2, PM10 and benzene in indoor air in their home were measured. The variables of distance of nearest street or way, traffic density and the time of using fuel gas for cooking were collected and a multiple linear regression model was established to estimate indoor air pollution level related traffic and fuel gas using for cooking. The associations between indoor air pollutants concentrations and respiratory symptoms and disease were analyzed with multiple Logistic Regression model. Results After potential founders being controlled, the significant associations were observed between per 20 ?g/m3 increase of indoor NO2 concentration and dry cough(OR1.12,95%CI1.03-1.20),morning cough(OR1.08,95%CI1.01-1.17), wheezing (OR 1.09,95%CI1.0-1.19), bronchitis (OR 1.21, 95%CI1.01-1.46). The similar effects were observed between the per 30 ?g/m3 increase of indoor PM10 concentration and dry cough(OR1.28,95%CI1.02-1.59),wheeze(OR1.34,95%CI1.04-1.71),current asthma (OR1.87,95%CI1.08-3.23). The significant associations were also observed between house was nearby major street/road (
