Methods A total of 320 children with mild asthma were selected as the study object. All the children were tested for lung function and serum magnesium level after admission. Symptom control was performed with the child asthma control test questionnaire (ACT). According to the ACT score, the children were divided into well controlled group, partial control group, and uncontrolled group. The differences of pulmonary function and serum magnesium level in children with different symptom control levels were analyzed and compared. Results The total serum magnesium level range was to mg/dL, and the prevalence of hypomagnesemia was % (17/320). The ratio of forced expir
