Reference data among general population and known-groups validity among hypertensive population of the EQ-5D-5L in Vietnam

Abstract

Purpose This study aims to provide EQ-5D-5L population norms among the general population in Vietnam and to test EQ-5D-5L’ construction validity among people living with hypertension there. Methods Descriptive statistics of the five dimensions and five levels, EQ-VAS and EQ-5D-5L indexes were categorised into gender and age groups for the EQ-5D-5L population norms. Known-groups testing was set for lower EQ-5D-5L outcomes among people who were aware of their hypertensive status, females, people with more comorbidities, less education, older ages, and higher body mass indexes. Level of confident interval was 95%. Results The mean EQ-VAS and EQ-5D-5L indexes were 81.10 (SD: 13.35) and 0.94 (SD: 0.09) among the general population. The EQ-5D-5L outcomes were better among younger people, males, people with more education, employees, and single people. Respondents reported fewer problems with self-care and usual activities and tend to have problems at higher levels across older ages. The known-group testing showed statistically significant results. The mean EQ-VAS and EQ-5D-5L indexes of people in the diagnosed hypertensive group (71.48 and 0.94, respectively) were statistically significantly smaller than they were in the non-hypertensive and undiagnosed hypertensive group (76.65 and 0.97; 76.95 and 0.96 accordingly). Statistically significant associations of lower EQ-5D-5L indexes and EQ-VAS were found among people diagnosed for hypertension, people suffering from an incremental comorbidity, and obese people. Conclusion This study has provided EQ-5D-5L population norms for the general population and evidence for known-groups validity of the EQ-5D-5L instrument among hypertensive people in Vietnam.

Health-Related Quality of Life Among Patients Recovered From COVID-19

“…The initial findings were lower than those of the study conducted by Barani et al of COVID-19 patients in India, which found that the utility value of EQ-5D-5L among COVID-19 patients was 0.925 (SD 0.150) 1 month after recovery. 23 Our findings were also lower than those of studies by Nguyen et al 19 and Mai et al 24 which assessed Vietnamese samples and revealed results of was 0.91 (SD 0.15) and 0.94 (SD 0.09), respectively. Moreover, our findings are significantly lower than the general population survey in the COVID-19 context in Vietnam, China, USA, and Switzerland.…”

Lifetime impact of being underweight or overweight/obese during childhood in Vietnam

“…Quality of life data were derived from a Vietnamese study [ 30 ]. For those aged 18–34 years, the utility scores were estimated from general population of 562 adults in Vietnam using the EQ-5D-5L instrument, but due to unavailability of weight data, the same utility values regardless of weight status were applied by sex and age groups.…”

In the same Vietnamese study [ 30 ], weight data were available for different population in Ho Chi Minh City ( n = 1,296), so utility values by sex, age groups and weight status for those aged 35 years and over were estimated accordingly. We applied utility values of 1 for children aged 5–17 years as utility data for children were not available.…”

“…The China Health and Nutrition Survey was approved by institutional review boards at the University of North Carolina at Chapel Hill and the National Institute of Nutrition and Food Safety [ 36 ]. The quality of life study in Vietnam was approved by the Ethical Review Board for Biomedical Research at the Hanoi University of Public Health [ 30 ]. All methods were carried out in accordance with relevant guidelines and regulations, and the study participants or caregivers of minors provided their informed consent [ 27 , 30 , 35 , 36 ].…”
