Overweight and obesity were defined based on the body mass index.Multiple logistic regression were used to obtain adjusted prevalence odds ratios (OR) and 95% confidence intervals (95% CI) between asthma symptoms and obesity.RESULTS: Finally, 7485 children were included (50.8% female).Our results shown that 23.4% of our children were overweight, and 9.6% were obese.The prevalence of wheezing ever was 39.0%, that of current asthma 13.5%, severe asthma 4.9%, and exercise induced asthma 6.4%.Obesity was associated with an increase in the probability of wheezing ever (OR: 1.35) and exercise induced asthma (OR: 1.62).View this table:Odds ratio for prevalence of asthma symptoms according to obesity and overweight in childrenCONCLUSION: In our population, obesity was associated with a higher prevalence of asthma in young children.
