Abstract

Background: Asthma prevalence is rising worldwide. Amongst the various factors influencing asthma control, the magnesium level of the affected individuals seems to make a major contribution to achieving asthma control through i ts anti - inflammatory and bronchodilation effects.This study therefore was aimed at determining the magnesium level of stable asthmatic children and its relationship, if any, with their levels of asthma control.
Methods: A cross-sectional study where the serum magnesium levels of 30 stable asthmatic children attending Asthma clinic and those of 30 children without asthma attending Children Out-patient clinic (CHOP) both at the University of Nigeria Teaching Hospital (UNTH), Enugu, were assessed using atomic absorption spectrophotometer. The levels of asthma control of children with asthma were assessed using asthma therapy
assessment questionnaire (ATAQ). Mean serum magnesium levels of the different asthma control levels were compared using the analysis of variance (ANOVA).
Results: The mean ages of children with asthma and those without asthma were 10.4 ± 2.98 years and 10.5 ±3.00 years respectively. The mean serum magnesium level of stable children with asthma (1.13 ±1.04 mmol/L) was found to be significantly lower than those of the non-asthmatic  controls (1.46 ±1.01 mmol/L), p= 0.004.A significant association was also found between the serum magnesium levels and the levels of asthma control (p = 0.015).
Conclusion: This study shows that the serum magnesium level of stable asthmatic children is significantly lower than that of children without asthma and there is a significant association between the mean serum magnesium levels and their levels of asthma control.
