ABSTRACT

The data about paternal or maternal smoking and the children’s pulmonary functions have been very inconsistent. Passive smoking, of paternal or maternal origin, is known to influence the development of children’s pulmonary function. Passive smoking was associated with reduced FEV, PEFR, and FEF25-75% (Haby et al., 1994; Beck et al., 1999). Passive smoking is a major contributing factor to the development and persistence of airflow limitation in wheezing children (Sherill et al., 1992).
