IntroductionThe aims of this systematic review and meta-analysis are to synthesise quality of life (QOL) of family caregivers of children and young adults with Down syndrome (DS) and determine factors affecting their QOL.MethodThis review was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Key search terms were "quality of life", "down syndrome" and "trisomy 21". Meta-analysis using random effect model was conducted where feasible. All studies underwent qualitative synthesis. The study protocol was registered with PROSPERO (CRD42023413532).ResultsEighteen studies with 1956 caregivers were included. Of the 10 studies utilising the World Health Organization Quality of Life Instrument-Brief Version, 5 were included in the meta-analysis. Psychosocial domain had the highest score with mean (95% confidence interval [CI]) of 63.18 (39.10-87.25). Scores were poorer in physical, environmental and social domains: 59.36 (28.24-90.48), 59.82 (19.57-100.07) and 59.83 (44.24-75.41), respectively. Studies were heterogenous with I2 values ranging from 99-100% (P<0.01). The remaining 8 studies used 6 other instruments. Qualitative synthesis revealed that caregivers' QOL was adversely affected by child-related factors, such as level of functional independence, developmental delay, presence of multiple comorbidities, impaired activities of daily living and poor sleep quality. Environmental factors that adversely affected caregivers' QOL included number of children, housing and support from the family. Personal factors that affected caregivers' QOL included age, being a single mother, low education and low income.ConclusionQOL of caregivers of children with DS was lower than population reference data. Understand-ing the factors that influence family caregivers' QOL is an essential step towards improving the QOL of caregivers and their children with DS.
