This study systematically assessed the psychological burden, physical function, and health-related quality of life in individuals with osteogenesis imperfecta (OI), revealing that despite declining physical function, OI patients show no significant differences in psychological domains compared to the general population, and exhibit higher psychological resilience. These findings provide new insights for the comprehensive management of OI.
Literature Overview
This article, titled Health-related quality of life in individuals with osteogenesis imperfecta in the United States: a cross-sectional study, was published in the Orphanet Journal of Rare Diseases. It reviewed and summarized the assessment results of mental health, pain, physical function, and quality of life in 26 OI patients in the United States. Using multiple standardized scales such as PHQ-8, GAD-7, and HAQ-DI, the study systematically analyzed the quality of life in OI patients and found that, although physical function was significantly impaired, the mental health burden was comparable to that of the general population, and psychological resilience was higher. The findings highlight the importance of comprehensive assessment in the long-term management of OI and provide references for future intervention strategies.
Background Knowledge
Osteogenesis imperfecta (OI), also known as 'brittle bone disease', is a genetic connective tissue disorder characterized by increased bone fragility, with a global prevalence of approximately 1/15,000–20,000. OI exhibits strong genetic heterogeneity, with approximately 90% of cases caused by mutations in the COL1A1 or COL1A2 genes, while the remaining 10% are mostly autosomal recessive. OI patients often present with multi-system features, such as blue sclerae, hearing loss, short stature, and dental abnormalities. Current research on OI mainly focuses on skeletal phenotypes, fracture prevention, and pain management, with limited systematic evaluation of mental health, social function, and quality of life. Although previous studies have used tools like SF-36 or PROMIS-29 to assess quality of life in OI patients, dimensions such as psychological resilience (grit) and pain catastrophizing remain largely unexplored. This study fills that gap by systematically evaluating grit and pain catastrophizing in OI patients compared to the general population, offering a more comprehensive approach to patient management in clinical settings.
Research Methods and Experiments
The study adopted a prospective cross-sectional design, recruiting 26 OI patients (23 females and 3 males) at the Hospital for Special Surgery in New York to complete standardized questionnaires, including SF-36, PROMIS-29, PHQ-8, GAD-7, HAQ-DI, PCS, and the Grit Scale. Demographic data, surgical history, psychiatric history, and assistive device use were also collected. Data were collected and managed via REDCap and analyzed using SPSS 29. Statistical analyses included one-sample t-tests, ANOVA, and non-parametric binomial tests to compare the scale scores between OI patients and the general population.
Key Findings and Insights
Implications and Future Directions
This study provides new evidence for the comprehensive assessment of psychological and physical domains in OI patients. It emphasizes the need for clinical management to focus on both physical and psychological aspects. Future studies should expand the sample size, especially for individuals with type III OI, and explore the underlying mechanisms of increased grit to develop targeted interventions. Additionally, modern normative data should be used for age, gender, and socioeconomic status matching to reduce bias. Further investigation into the relationship between impaired social function and psychological interventions is also needed to provide more personalized support for OI patients.
Conclusion
This study reveals that, although OI patients exhibit significantly impaired physical function, their mental health burden is comparable to that of the general population, and they demonstrate higher psychological resilience. This dissociation between psychological and physiological status may provide new insights for clinical management, suggesting that in addition to focusing on fractures and bone pain, psychosocial support and social function recovery should not be neglected. Furthermore, this is the first study to apply the grit scale to assess psychological resilience in OI patients, opening a new avenue for future research. It is recommended that comprehensive management strategies be adopted in clinical settings, including grit training, pain management, and social support interventions, to improve the overall quality of life in OI patients. Larger sample sizes and multi-center studies are needed in the future to confirm these findings and explore the specific mechanisms and interventions that enhance psychological resilience.
