[Absence of a relationship between obesity and asthma in prepubertal Moroccan children]

Obesity and asthma are both public health problems that have been increasing for several years. This increase suggests that there may be a connection between these two pathologies. The aim of this study was to examine the relationship between obesity and asthma by measuring the prevalence of obesity in asthmatic children compared with a control population, by analysing the impact of obesity on the severity of the asthma, and by examining the relationship between obesity and atopy. The study was based on 100 children aged from 4 to 16 years in whom the diagnosis of asthma was confirmed; obesity being defined as a body mass index greater than the 97th percentile. The prevalence of obesity in these patients was 14%. Obesity was not a factor in the severity of the asthma as 14.5% of the severe asthmatics were obese compared with 18.75% of the mild and moderate asthmatics. 13% of the atopic subjects were obese compared with 13% of the non-atopics. Obesity does not constitute, therefore, a risk factor for asthma and does not contribute to the severity of the disease. In addition there is no relationship between obesity and atopy.
