Fig. 1From: Quality of life and health status of hospitalized adults with congenital heart disease in Vietnam: a cross-sectional studyPoor quality of life by subgroups in adults with congenital heart disease. Poor quality of life (QOL) was defined as EQ-VAS < 65. The prevalence of poor QOL in patients who were aged > 30 years was higher than those aged ≤ 30 years (50%, n = 35 vs 25.6%, n = 10, p = 0.013; using the Chi-square test; respectively). The prevalence of poor QOL in patients with an educational level of high school and below was higher than in those with an educational level of high school and above (55.1%, n = 27 vs 28.6%, n = 16, p = 0.006; using Chi-square test; respectively). The prevalence of poor QOL in patients with an unemployed status/unstable employment was higher than in those with an employed status (66.7%, n = 18 vs 37.6%, n = 35, p = 0.001; using Chi-square test; respectively).
