ABSTRACT
OBJECTIVE:
To determine the effects of second-hand smoke in the respiratory system of children under 5 years old.METHODS:
A cross sectional study of a total of 1,104 children under 5 years old. Information about respiratory symptoms and illness, family history of respiratory diseases, smoking habits of household members and housing conditions were assessed by home interviews with the children's parents.RESULTS:
We studied 546 boys and 558 girls. Among 611 children exposed to second-hand smoke, 82% had respiratory problems (odds ratio = 1.64; 95% confidence interval 1.21-2.20). Children whose parents were smokers at the time of the survey were more likely to experience wheezing than children of nonsmoking parents (odds ratio = 1.66; 95% confidence interval 1.21-2.27), shortness of breath (odds ratio = 1.91; 95% confidence interval 1. 36-2.67), morning and day time or night coughs (odds ratio = 1.58; 95% confidence interval 1.09-2.28). The odds ratio for asthma, bronchitis and pneumonia was greater for children exposed to second-hand smoke (odds ratio = 1.60; 95% confidence interval 1. 11-2.31).CONCLUSIONS:
Maternal smoking, paternal smoking, family history of respiratory diseases, and housing conditions are considered risk factors for respiratory diseases in children.
