Sleep disturbances are commonly reported by parents of children and adolescents with epilepsy. However, evidence synthesis including quality and quantity of sleep in parents of children and adolescents with epilepsy is lacking. This systematic review and meta-analysis was conducted to quantify pooled mean estimates of parental sleep variables and to determine the prevalence of sleep disturbances in parents of children and adolescents with epilepsy. Five electronic databases, PubMed, Medline, Embase, PsychINFO, and CINAHL, were systematically searched from inception to September 2021. Eleven observational studies examining parents of pediatric patients aged <18 years with epilepsy using a quantitative measure of sleep duration, sleep quality, or sleep disturbance were reviewed. Our results showed that the pooled nocturnal sleep duration was 5.93 hours (95% CI: 4.64 to 7.21 hours). Overall sleep quality as estimated by the bias-adjusted pooled Pittsburgh Sleep Quality Index total score was 6.65 (95% CI: 5.98 to 7.33). Parents of children with epilepsy had significantly higher Pittsburgh Sleep Quality Index total scores compared to parents of healthy children (differences in means 1.84, 95% CI: 1.29 to 2.39). The pooled estimated prevalence of parental sleep disturbances was 58.1% (95% CI: 45.7% to 69.6%). Our findings demonstrate a high prevalence of sleep disturbances with poor sleep quality and substantial reductions in sleep time in parents of children and adolescents with epilepsy. Healthcare professionals in pediatric neurology clinics should proactively initiate screening for sleep disturbances in parents of children and adolescents with epilepsy and refer parents to a sleep specialist when necessary.
