Pattern and determinants of health-related quality of life of adolescents with congenital heart disease in Cameroon: A single-center cross-sectional study.

ABSTRACT

Background: Health-related quality of life (HRQoL) assessment is necessary for the management of patients with congenital heart diseases (CHD). No study has yet been reported on Cameroonian adolescents. The aim of this study was to evaluate the profile of and look for determinants of HRQoL in adolescents with CHD in Cameroon. Methods: This was a cross-sectional study with prospective recruitment carried out on 71 adolescents diagnosed with CHD aged 12 to 18 years and recruited at the Douala General Hospital. Sociodemographic and clinical data were collected using a structured questionnaire. HRQoL was assessed using the pediatric quality of life inventory (PedsQL4.0) for child and parent reports. Multivariate linear regression was used to assess the determinants of HRQoL. Differences were considered significant for p < 0.05. Results: Mean age of participants was 15 ± 2 years with 54.9% women. Mean physical and psychosocial functioning scores were 50.7 ± 13.9 and 60.5 ± 9.6 for parent report and 49.5 ± 13.4 and 59.1 ± 9.1 for child report respectively; with no significant difference according to gender. Distribution of functioning scores according to anatomical complexity showed no significant difference while it was lower in patients with a greater physiological severity and to those with no surgical intervention compared to the others. After multivariate adjustments, physiological stage 3 or 4 was negatively associated while cardiac intervention was positively associated with HRQoL. Conclusion: CHD adolescents exhibit a low level of quality of life. Cardiac intervention positively affects HRQoL and should be targeted in the reduction of HRQoL burden from CHD in Cameroon.
