Resumen:
OBJECTIVES:To evaluate the influence of demographic, socioeconomic,
and risk factors variables on the EQ-5D time trade-off
[TTO] and visual analogue scale [VAS] population values as well
as in the self-reported health by VAS [VAS-SR] in Argentina.
METHODS: We included data from 41,392 adults in the first
National Risk Factor [RF] Survey (2005), a general population
nationally representative sample. Survey variables included selfreported
sociodemographic parameters and RF (diabetes [DBT],
high blood pressure [HBP], dyslipemia [DLP], obesity [OB],
smoking [SMK], healthy diet [HD], physical activity [PA], as well
as the EQ-5D instrument (including the descriptive system and
the VAS-SR item). TTO and VAS preference values were mapped from a local EQ-5D Value study. We assessed the independent
relationships between EQ-5D scores (TTO and VAS) as well as
the VAS-SR with sociodemographic variables and RF. We used
multivariable linear regression modeling. We considered clinically
meaningful a coefficient of >=0.02. RESULTS: Final models
included 33,964 subjects, representing 17,586,759 Argentineans,
and had an R2 of 0.16?0.19. In fully adjusted models, the following
variables were statistically, consistently, and clinically
associated with both TTO and VAS EQ-5D scores as well as
VAS-SR: age, gender, income, selected provinces, health coverage,
DBT, HBP, DLP, PA, with coefficients ranging from 0.02 to
0.09. Though there were statistical differences among housing,
household, education, employment status, gender of household
head, SMK, OB, and HD subgroups, they had a small magnitude
(coefficients < 0.02) or were not consistently associated with
TTO/VAS/VAS-SR. CONCLUSIONS: In Argentina, in addition
to sociodemographic factors, diabetes, hypertension, physical
activity and dyslipemia, were significantly and strongly associated
with scores on the EQ-5D as well as with self-reported VAS.
This is, to our knowledge, the first study in Latin America that
evaluates the determinants of EQ-5D weights and VAS-SR using
a general population health survey as well as locally derived
weights.
