Quality of life of mothers of children and adolescents with mental health problems in Mongolia: associations with the severity of children's mental health problems and family structure.

Background: In low- and middle-income countries (LMICs), most parents of children with mental health problems receive limited support from social and health services while caring for their children. However, research on the quality of life (QOL) of these parents in LMICs is limited. This study aimed to investigate the association between maternal QOL and children's mental health problems, and other related factors in Mongolia. Methods: A cross-sectional analysis of children aged 4-17 years who lived in Ulaanbaatar and visited the National Mental Health Centre in Mongolia and their mothers was conducted. The mothers' QOL was assessed using the WHOQOL-BREF, and the severity of children's mental health problems was assessed using the Strengths and Difficulties Questionnaire (SDQ). Multivariate linear regression analyses were performed using the mothers' WHOQOL domain scores as dependent variables and the children's SDQ scores and demographic and socioeconomic factors as explanatory variables. Results: A total of 242 child-mother dyads were included in this study, and 231 dyads were included in the multivariate regression analyses. Children's SDQ internalising scores were negatively associated with all four maternal QOL domain scores, while their externalising scores were negatively associated with maternal physical and psychological domain scores. Non-cohabitation of fathers was negatively associated with physical, social, and environmental domain scores, and non-cohabitation of grandparents was associated with psychological and environmental domain scores. Conclusions: In Mongolia, maternal QOL is influenced by the severity of children's mental health problems and family member support. These findings highlight the importance of developing systems to support all families.
