Abstract
RATIONALE: Phenylketonuria (PKU) is a metabolic condition that requires treatment for life. There is increasing evidence that chronic illnesses put strain on relationships and marriages. However, no studies have examined the unique factors that metabolic conditions have on affected individuals and their relationship satisfaction. We surveyed a population of adult patients with PKU and assessed how management, treatment, and lifestyle factors impact their relationship satisfaction. PURPOSE: The purpose of our study was to explore whether factors such as involvement of partner in PKU management, impact of challenges unique to PKU (e.g., diet, family planning, mood disturbances), and PKU treatment types were associated with the degree of relationship satisfaction. METHOD: We surveyed adult patients with PKU (n = 82) who were either currently in or had previously been in a long-term relationship. We developed a 78-question survey that included unique questions regarding lifestyle, treatment, and management of their PKU in addition to a validated Relationship Assessment Score. Questions included single choice, multiple choice, and 3 open-ended questions. RESULTS: We found that higher relationship satisfaction was associated with increased partner involvement, increased health, and adherence to recommended PKU treatments. Participants utilizing both diet and pharmaceutical treatment had the highest relationship satisfaction. Finally, participants who reported that their PKU did not contribute to the ending of a previous relationship reported higher relationship satisfaction scores. CONCLUSION: This study suggests that involvement of partners in the management and treatment of a chronic illness and adherence to recommended treatments can significantly improve relationship satisfaction.
