Caregivers' burden and its influencing factors among parents of children with asthma and comorbidities: a cross-sectional study

The caregiver burden among parents of children with asthma and comorbidities is substantial. Factors associated with higher burden levels include longer asthma course, greater number of comorbidities, longer comorbidity course, part-time employment status, and poor asthma control. Conversely, higher levels of perceived social support, older child age, and medical insurance and commercial insurance coverage were associated with lower burden levels. These findings provide an empirical basis for clinical institutions, communities, and relevant departments to inform the development of targeted interventions aimed at alleviating this caregiver burden. It should be noted that this study employed a cross-sectional design, and future longitudinal research is needed to verify causal relationships.
