Asthma Symptoms with Parental Smoking

International study results show paternal and maternal cigarette smoking is associated with a greater risk for signs and symptoms of asthma, rhinoconjunctivitis and eczema in children, rendered from research results out of New Zealand.

The significance of the odds ratio was increased for symptoms associated with asthma more than the other outcomes, according to investigators.

Researchers analyzed written questionnaires from parents of children 6 to 7 years of age about their child’s allergy signs and symptoms and their own smoking habits in the child’s first year of life.

Questionnaires also were obtained from teens aged 13 to 14 years of age whose parents currently continued to smoke.

Maternal smoking was identified with higher odds ratios than was paternal smoking, and maternal smoking in the child’s first year of life was associated with a increased risk for signs and symptoms for all outcome classes than was current maternal smoking.

This demonstrates that early exposure to environmental second-hand tobacco smoke is remarkably important, according to investigators.
