摘要

Background: Although a large number of studies of asthma had been conducted, the etiology of childhood asthma is not yet established. Both life style factors and environmental exposure during early life may play important roles. Objective: To evaluate the risk factors for asthma in Iraqi primary school children. Patients and Methods: The sample consisted of 2875 children, who were between 11 and 14 years of age at the time of enrollment in the Regional Study of Asthma and Allergies in Childhood (RSAAC) and were subsequently followed up at their schools. Results: The prevalence of asthma when assessed by interview was 7.2% [95% confidence interval (CI) 6.3% - 8.3%], while it was 8.9% [95% CI 7.9 % - 10.0%] when assessed by clinical examination. There was no significant difference between the prevalence of asthma in males and females. Exposure to wood or oil smoke (Odds-ratio (OR)=2.40, 95% CI 1.84–3.17; P<0.001); cats and dogs (OR=2.95, 95% CI 2.15–4.04; P<0.001); herbicides and /or pesticides (OR=1.68, 95% CI 1.16–2.43; P=0.005); farm animals, farm crops or dust (exposure to animals OR= 2.97, 95% CI 2.02–4.37; P<0.001; exposure to farm crops (OR=2.17, 95% CI 1.33–3.55; P=0.002); and breastfeeding (OR=8.5, 95% CI 6.10-11.84; P<0.001) were significantly associated with asthma. Family history of asthma (OR=4.11, 95% CI 3.16-5.34; P<0.001) and atopy (OR=2.33, 95% CI 1.79-3.04; P<0.001) were associated with an increased prevalence of asthma. In addition, family history of smoking was associated with asthma (OR=1.52, 95% CI 1.17-1.97; P=0.001). Presence of skin problems (OR=2.40, 95% CI 1.63-3.55; P<0.001), gastro intestinal problems (OR=5.64, 95% CI 2.23-14.25; P<0.001) and food allergy (OR=6.08, 95% CI 2.96-12.52; P<0.001) were significantly associated with asthma in childhood. Maternal education (p<0.001) and social status (p=0.001) may be a risk markers for asthma in childhood. Conclusion: These results suggest that both environmental exposure and lifestyle factors are important risk factors for childhood asthma in Iraqi children. Both indoor and outdoor environmental exposure may play a crucial role in the etiology of childhood asthma.
