What predicts the proxy-reported health-related quality of life of adolescents with cerebral palsy in Bangladesh?

Abstract

Background : The health-related quality of life (HRQoL) of adolescents with CP in low and middle-income countries is often poor, as is the case in Bangladesh. This exploratory study examined what factors predict the proxy-reported HRQoL of adolescents with CP in rural Bangladesh, a typical low- and middle-income country (LMIC). Methods: Adolescents with CP (10 to 18y) were identified using the Bangladesh Cerebral Palsy Register. HRQoL was assessed using the Cerebral Palsy Quality of Life-Teens proxy-report questionnaire (CPQoL-Teens), adolescent mental health using the Strengths and Difficulty Questionnaire (SDQ) and caregiver mental health using the Depression, Anxiety and Stress Scale (DASS-21). Theoretical and statistical interests (i.e. bivariate analysis, p < 0.05) identified potential predictors which were entered into hierarchical multiple linear regression (HMLR) models in order of clinical significance; HMLR related adolescent clinical characteristics, adolescent and caregiver mental health and proxies of socioeconomic status to CPQoL-Teens dimensions. Results: One hundred fifty-four adolescents with CP (mean age 15y 1mo, SD 1y 8mo, female 31.2%) participated in this study. Twenty-four factors were identified to explore for relationship to adolescent proxy-reported HRQoL. Fifteen of the factors correlated to one or more CPQoL-Teens dimension; strongest correlation was between 'feelings about functioning' and motor impairment (r = 0.545). Nine were predictive of CPQoL-Teens dimensions; adolescent sex, school attendance, severity of motor impairment, hearing and speech impairment, mother's education, primary caregiver depression and stress, and having a sanitary latrine at home resulting in score changes of between 0.79 (95% CI 0.24 to 1.35) to 35.1 (95% CI 6.03 to 64.22). Conclusions: Many of the factors predicting the proxy-reported HRQoL of adolescents with CP are amenable to intervention, and have the potential to improve adolescent wellbeing. Several determinants are priorities of the sustainable development goals (SDGs); these findings should inform resource prioritization to improve the wellbeing of adolescents with CP in Bangladesh and other LMICs.
