ABSTRACT
Background: Obesity and overweight increased the risk of asthma. Objective: The aim was to investigate the impact of energy-restricted diet for obese asthmatic adults to improve health-related quality of life. Subjects & Methods: A one group pre-post-test intervention study was conducted on 70 obese asthmatic patients who had persistent clinically significant chronic airflow obstruction despite anti-asthmatic therapy. The study patients were recruited from three different family health centers in Alexandria governorate, Egypt. Data about socio-demographic characteristics, clinical history of asthma, Arabic version for disease specific quality of life interview questionnaire (AQLQ), and anthropometric measurements were collected at the time of personal interview. Results: The total AQLQ score increased (from a mean 3.18±0.46 to 4.80±0.42) with all its four domains: symptoms (from a mean 3.11±0.35 to 5.0±0.2), limitation (from a mean 3.18±0.35 to 4.86±0.3), emotion (from a mean 3.17±0.46 to 4.9±0.43), and environment (from a mean 3.22±0.45 to 4.22±0.46). Patients’ body weights decreased losing a mean 11.5% from the pre-intervention body mass index (from a mean 40.7±9.19 to 36.02±8.70). Conclusion: The improvement in health-related quality of life among obese asthmatic patients following low caloric diet for weight reduction with decreased body mass index and body fat percentage can be concluded. Weight and body fat reduction in obese adults with asthma is recommended to improve health-related quality of life.
