Systematic Review: Diabetes Family Conflict in Young People With Type 1 Diabetes

Abstract

Objective: To investigate the relationships between diabetes-specific family conflict and health outcomes of young people with type 1 diabetes (T1D).

Methods: A systematic review was performed according to the PRISMA statement (registration number: CRD42020164988). PubMed, Embase, PsycNET, reference lists of included studies, and other relevant reviews were searched (1990-2020). Two independent reviewers screened titles, abstracts, and full-texts. Studies were included if they sampled young people with T1D (mean age between 14 and 25 years) and examined the relationship between diabetes-specific family conflict and the following outcomes: glycated hemoglobin (HbA1c), treatment adherence, blood glucose monitoring, depression, anxiety, quality of life, and/or well-being.

Results: A total of 20 studies met the predetermined inclusion criteria. Greater diabetes-specific family conflict was significantly related to higher HbA1c values in 17 studies. Seven studies reported a significant association between greater diabetes family conflict and suboptimal treatment adherence and/or less frequent blood glucose monitoring. However, significant relationships between conflict and HbA1c and/or treatment adherence were not found in four studies. Seven studies in total reported that greater diabetes family conflict was significantly related to poorer quality of life or well-being and greater depressive and/or anxiety symptoms in young people.

Conclusions: Diabetes-specific family conflict is associated with some adverse health outcomes for young people with T1D. However, more longitudinal studies of young people aged older than 16 years are needed. Screening for and addressing diabetes-specific family conflict is recommended, given the growing number of studies linking family conflict to various adverse health outcomes in young people with T1D.
