Abstract: 

Background: Even though cigarette smoking is a known risk factor for many chronic illnesses such as coronary heart and chronic obstructive pulmonary diseases, its effect on the development of asthma is still controversial. Indeed, most studies do not significantly associate asthma with current smoking, although others report an increased risk in former and current smokers compared with nonsmokers The aim of this study was to determine the association between parents’ daily cigarette number and the risk of their children’s asthma.
Materials and method: A case control study conducted among asthmatic children who referred to children medical center during 2005-2007. We interviewed 215 patients with physician diagnosed asthma and age under 13 years old. Questions about their parents smoking situation and their daily cigarette number were asked. Patients were matched with 215 healthy children with the same age and sex as control group. Finally data were analyzed by SPSS statistic software.
Results: Results showed an increasing rate of smoking in case group and 16.5% of patient’s parents had daily cigarette number of more than 20 versus 7.6% in control group. We found Odds Ratio (OR) =2.38 for parents who had smoked more than 5 cigarettes compared with those who had not smoked or smoked less than 5 cigarettes per day CI: 1.26-4.55 and P=0.0059170.
Discussion: Curiously enough, the risk of asthma seems to increase with the number of daily cigarettes in occasional to moderate smokers but to decrease in heavy smokers. Smoking effect of asthma is complex and contradictory. In this study we show that parents’ smoking is an important risk factor for children asthma. It deserves more attention and further studies.
