Wellbeing and quality of life among parents of individuals with Fontan physiology.

PURPOSE: To examine global and health-related quality of life (QOL) among parents of individuals with Fontan physiology and determine associations with sociodemographic, parent and child-related health, psychological, and relational factors.

METHODS

Parents participating in the Australian and New Zealand Fontan Registry (ANZFR) QOL Study (N = 151, Parent Mean age = 47.9 ± 10.2 years, age range: 31.6-79.6 years, 66% women; child Mean age = 16.3 ± 8.8, age range: 6.9-48.7 years, 40% female) completed a series of validated measures. Health-related QOL was assessed using the PedsQL 4.0 Core Generic Scales for adults and global QOL was assessed using a visual analogue scale (0-10).

RESULTS

Most parents (81%) reported good global QOL (≥ 6), consistent with broader population trends. Nearly one-third of parents (28%) reported at-risk health-related QOL (based on total PedsQL scores) with physical functioning most affected (44%). Psychological factors, including psychological stress and sense of coherence, emerged as the strongest correlates of global and health-related QOL, explaining an additional 16 to 30% of the variance (using marginal R2). Final models explained 35 and 57% and of the variance in global and health-related QOL, respectively (marginal R2). Relational factors, including perceived social support and family functioning contributed minimally when analyzed alongside psychological variables.

CONCLUSION

While parents of individuals with Fontan physiology report good global QOL, challenges in health-related QOL exist. We identified key psychological, sociodemographic, and health-related factors associated with parental QOL outcomes. These data may aid early identification of physical and psychosocial difficulties and guide targeted health resource allocation for this population.
