Neurofibromatosis type 1 (NF1) is a genetic, autosomal dominant multi-organ disease characterized by susceptibility to tumor formation, changes in skin pigmentation, skeletal abnormalities, and neuropsychological deficits. Clinical studies have shown impaired health-related quality of life (HQoL) in adults with NF1. However, little is known about HQoL in non-clinical NF1 samples. We conducted a cross-sectional self-report survey of 142 persons with NF1 (M age = 50.3 years, SD = 12.0, range 32 to 80; 62.0% females) recruited from non-clinical settings. Several HQoL domains, including life satisfaction, mental health, sleep, pain, gastrointestinal problems, oral health, and social support, were compared between the NF1 sample and 46,293 controls from the HUNT3 population study. We also examined gender differences within the NF1 sample and predictors of HQoL. Compared to controls, the NF1 sample reported significantly poorer life satisfaction, mental health, sleep, and oral health, and more pain, gastrointestinal problems, comorbid diseases, and memory problems. Several HQoL domains were significantly correlated. Mental health was the only unique significant predictor of overall life satisfaction. Women with NF1 reported significantly more mental health, sleep, and pain problems than men with NF1. Mental health assessment and management should be integrated into clinical care of persons with NF1 to potentially improve their HQoL.
