Background: Asthma, a chronic respiratory disease, affects millions of children globally. Malnutrition and poor nutrition are prevalent among these children and may worsen asthma symptoms. This study aims to determine if improving asthma severity correlates with better nutritional parameters in pediatric asthma patients. Methods: This observational study involved non-obese children aged 5-12 years with asthma, treated according to standard protocols. Nutritional assessments, including weight, height, and BMI measurements, were conducted at baseline and at the end of the study period.Patients were categorized into two groups based on their change in asthma severity during the study period: those with improved asthma severity and those with no improvement or worsening of asthma severity. The two groups were compared for changes in nutritional parameters from baseline to the end of the study period. Data Analysis: Data analysis used t-tests and chi-square tests, with a p-value of less than 0.05 deemed statistically significant. Results: In children with asthma, those with improved asthma severity (n=63) showed significant increases in weight (1.2 kg ±0.8, p=0.032), height (3.5 cm ±1.2, p=0.014), and BMI (19.5 ±2.1, p=0.045) compared to the no improvement/worsening group (n=37). Dietary intake did not differ significantly (p=0.120). Conclusion: The study highlights the importance of asthma control in non-obese pediatric patients for managing symptoms, enhancing growth, nutritional status, and quality of life.
