Abstract
OBJECTIVE: This study investigates the relationship between vitamin D levels and asthma control in children. METHODS: A total of 100 Moroccan children (2-16 years) with asthma were assessed for serum vitamin D levels using LC/MS-MS. Asthma control was evaluated according to the GINA guidelines and the C-ACT Test. RESULTS: Among the participants, 69% had well-controlled asthma, while 31% exhibited partially controlled or uncontrolled asthma. Despite a high prevalence of vitamin D deficiency, no significant correlation was found between vitamin D levels and asthma control. Multivariate analysis, adjusting for age, BMI, and sex, confirmed that there was no significant association between vitamin D levels and asthma control (OR = 1.02; 95% CI: 0.90-1.16, P = .72). CONCLUSIONS: Children with asthma have a high incidence of vitamin D deficiency. However, the results are not consistently in favor of a correlation between vitamin D levels and the level of asthma control.
