Abstract
Asthma is the most common chronic illness in childhood and is characterized by variable airflow obstruction with airway hyper-responsiveness. Asthma is a multifactorial disease that has been associated with genetic, environmental factors. Childhood obesity is a growing epidemic, with 32% of children in the United States being categorized as overweight or obese in 2016. Both asthma and childhood obesity are negatively affected by similar factors such as nutrition and physical activity. These factor similarities could be a significant link between the two diseases. The CDC identified a relationship between asthma and obesity in adults, indicating that in 2010 there were 12% more obese adults with asthma in the U.S. than past years. The research findings on the childhood obesity epidemic lack consistency when examining risk association to asthma in children and adolescents. For that, our study aimed to decrease the burden of childhood asthma by evaluation of the associated risk factors for asthma specially obesity.
A descriptive cross sectional prospective study was conducted among obese asthmatic and non-obese asthmatic children with age group from 3 years to 12 years at Suez Canal University hospital in Ismailia Egypt. Data was collected from the study population using a predesigned questionnaire included full history of their disease.
Our study showed that obese participants formed about 64.3% of the asthmatic patients, while non-obese participants formed about 35.7 % of the asthmatic patients. Obese participants were found to have significantly lower age than non-obese patients (p<0.001). About half of the sample had positive family smoking history (52.4%) and
