In one study, high body mass index (obesity or overweight) was associated with asthma at all ages. Another study showed obesity negatively impacted asthma control. In a Japanese study, the cutoff for BMI prediction of asthma was lower than the Westerns. Consistently, race and ethnicity were shown to influence the association between obesity and asthma.
The aim of this study was to explore whether Emeriti asthmatic children have higher body mass index (BMI).
Methods: This cross-sectional study involved public school children (age = 12 to16 years in the 7th and 8th grades) in the Eastern province of United Arab Emirates (UAE). A questionnaire (21 exploring questions to be answered by the parents) was given to 1,218 students of the chosen classes. Eight hundred ninety one (73%) students retuned the survey and were included in the study. Other collected data included students’ height, weight, FEV1 and PEF.
Results: The prevalence of asthma was 13% (115 of 891 students). There were no difference in the asthma prevalence among males and female (p=0.159). BMI (mean ± SD) for the asthmatics was 21.43 ± 7.01 and non-asthmatics 20.22 ± 5.53 (p=0.076). Atopic dermatitis (p=0.001), allergic rhinitis (p<0.001) and food allergy (p<0.05) were higher among the asthmatics.
Conclusions: BMI was higher among asthmatics, although the difference did not reach a statistical significance. Atopic disorders significantly clustered in asthmatic children.
