Factors associated with the psychological quality of life among adolescents with rare diseases in China: a national repetitive cross-sectional study

Abstract

Objective: To explore the factors associated with the psychosocial quality of life (QoL) among adolescents with rare diseases (RDs). Methods: We used cross-sectional design to collect data in February 2016 and February 2018, respectively, in China through a structured questionnaire. Those included in the study were adolescents aged between 10 and 18 who had a doctor-diagnosed RD. Multivariable linear regression was used to identify the predictors associated with psychosocial QoL among adolescents with RDs. Results: The study included 737 adolescents (28.4% girls). The mean score of their psychological QoL was 43.79 (SD = 20.44). Multivariable linear regression analysis suggests that girls had a lower psychological QoL than boys (adjusted coefficient = −1.87, 95% CI = [−3.53, −0.21]); and receiving an education (adjusted coefficient = 6.53, 95% CI = [4.47, 8.33]), living with parents (adjusted coefficient = 6.45, 95% CI = [3.94, 8.97]), and physical function (adjusted coefficient = 0.53, 95% CI = [0.49, 0.56]) were positively associated with psychological QoL. Conclusion: This study reveals the status of psychological QoL among adolescents with RDs. The evidence provided can increase our understanding of the factors associated with psychological QoL among adolescents with RDs and can help formulate policies and put concrete actions into practice.
