Severe bronchial asthma, Body mass index, Obesity


Background and Aim: Obesity and asthma have become more common in the general population, particularly among women, all over the world. Numerous research has been carried out on association of asthma with body mass index in general. The present study aimed to assess the clinical association of body mass index with severe bronchial asthma in women.

Patients and Methods: This prospective study was conducted on 486 severe bronchial asthma women in the Department of Community Medicine, Lahore General Hospital, Lahore Pakistan from March 2022 to March 2023. All the women with an age range 18-50 years diagnosed of acute bronchial asthma were included. Based on BMI, subjects were divided into three categories: (i) Normal weight (<25 Kg/m2), (ii) Overweight (26-30 Kg/m2), and (iii) Obese (>30 Kg/m2). Respiratory symptoms, medication use, and healthcare utilization were different parameters of severity of asthma measured and recorded.  

Results: The overall mean age of enrolled women was 42.14± 7.62 years. Of the total 486 women, the incidence of normal, overweight, and obese patients was 33.7% (n=164), 30.9% (n=150), and 35.4% (n=172) respectively. A significantly positive association is observed between asthma duration and BMI which indicates that chronic asthma women are more prone to gain weight. The incidence of mild, moderate, and severe asthma was 64.2% (312), 28% (n=136), and 7.8% (n=38) respectively.

Conclusion: The present study found that obesity is a risk factor for acquiring weight in asthmatic females. BMI rises with duration of asthma result in increased in asthma symptoms and severity. Patients with a high BMI are more likely to have co-morbid disorders.
