Abstract
Background
Despite therapeutic advances, asthma prevalence remains high. Psychosocial factors, including maternal mental disorders, may be involved. This study aims to evaluate the association of maternal common mental disorders (CMDs) and their change over time with asthma morbidity in the child and to observe the effect of social support on this association.
Methods
This prospective study involved 189 dyads of mothers and their asthmatic children aged between 2 and 14 years, assisted in specialized outpatient clinics. We measured the association of maternal CMD evolution (absent, maintained, or improved over time) with asthma control and visits to the emergency department (ED) due to asthma attacks through Poisson regression analysis. We further stratified the sample according to social support levels to identify a possible effect of this variable on the association of maternal psychological symptoms with asthma morbidity.
Results
Compared with mothers who maintained CMD over time, maternal CMD absence had a protective effect on the occurrence of visits to the ED (RR: 0.45; 95% CI: 0.26-0.79) and maternal CMD improvement was associated with lower risk of uncontrolled asthma in the child (RR: 0.60; 95% CI: 0.37-0.97). There was a stronger association of maternal CMD improvement with asthma control in the child only for the stratum of mothers with high social support in its three dimensions (affective-social interaction, emotional-informational, and material dimensions).
Conclusions
Maternal CMD absence and improvement over the study period were protective factors for uncontrolled asthma in the child, mainly in the presence of high social support.
