The current study aimed to evaluate the status of anxiety among caregivers of children with epilepsy and examine the associated factors.A cross-sectional study was conducted in western China, which consecutively recruited children with epilepsy in 2018. The self-rating anxiety scale (SAS) was used to assess the status of anxiety among caregivers of children with epilepsy. We collected information about aspects of sociodemographic data, disease status, attitude of caregivers towards the disease and family conditions as independent variables, using multiple linear regression to analyze factors related to the status of anxiety among caregivers.A total of 334 participants were included in the study with a response rate of 95.4% (334/350). The mean age of children with epilepsy was 6.05 ± 4.11 years. 7.2% (24/334) of patients were newly diagnosed and 55.4% (185/334) of patients presented with generalized epilepsy. A total of 25.7% (86/334) of caregivers among children with epilepsy presented the symptom of anxiety, with the scores of SAS 44.31 ± 10.558. SAS scores were negatively correlated with the children's age (B = -0.141; standard error = 0.135; P = .008), attitude towards seizures (B = -0.153; standard error = 1.192; P = .004) and medical expenses payment (B = -0.169; standard error = 1.703; P = .002).Symptoms of anxiety are common among caregivers of children with epilepsy in western China. Healthcare providers should pay more attention to caregivers with younger children, difficult financial situation, and greater fear of seizures. Exploring mental health interventions for caregivers is important.
