abstract: 'Introduction: Untreated dental caries (UC), although preventable, is the
|
|
|
|
|
|
|
|
|
|
most prevalent disease in the United States. UC diminishes quality of
|
|
|
|
|
|
|
|
|
|
life and lowers productivity for millions of Americans and is notably
|
|
|
|
|
|
|
|
|
|
higher among lower-income compared to higher-income persons. Objective:
|
|
|
|
|
|
|
|
|
|
This study examines changes in disparities by income in past-year dental
|
|
|
|
|
|
|
|
|
|
use (DU) and UC in 4 life stages (2-5, 6-19, 20-64, and >= 65 y) between
|
|
|
|
|
|
|
|
|
|
1999-2004 and 2011-2016. We also examined changes in dental safety net
|
|
|
|
|
|
|
|
|
|
policies during this time. Methods: We obtained data on dependent
|
|
|
|
|
|
|
|
|
|
variables, UC and DU, from cross-sectional, nationally representative
|
|
|
|
|
|
|
|
|
|
surveys for 1999-2004 and 2011-2016. We used multivariable regression
|
|
|
|
|
|
|
|
|
|
models with 3 main-effect explanatory variables: income (<200\% or >=
|
|
|
|
|
|
|
|
|
|
200\% federal poverty level), life stage, and survey period (1999-2004
|
|
|
|
|
|
|
|
|
|
or 2011-2016) and sociodemographic variables. We included 2-way
|
|
|
|
|
|
|
|
|
|
interaction terms among main-effect variables to test whether
|
|
|
|
|
|
|
|
|
|
disparities had changed over time in each life stage and a 3-way term to
|
|
|
|
|
|
|
|
|
|
test changes in disparities differed across life stages. Results:
|
|
|
|
|
|
|
|
|
|
Model-adjusted disparities in DU decreased for both preschool-age and
|
|
|
|
|
|
|
|
|
|
school-age children, and disparities in UC decreased for school-age
|
|
|
|
|
|
|
|
|
|
children. Changes in DU and UC disparities were not detectable for
|
|
|
|
|
|
|
|
|
|
working-age adults and increased for retirement-age adults. Changes in
|
|
|
|
|
|
|
|
|
|
DU and UC among preschool and school-age children were not significantly
|
|
|
|
|
|
|
|
|
|
different from one another and were significantly different from changes
|
|
|
|
|
|
|
|
|
|
among retirement-age adults. Compared to working-age adults, changes in
|
|
|
|
|
|
|
|
|
|
disparities for DU and UC were significantly different for school-age
|
|
|
|
|
|
|
|
|
|
children, and changes in DU were significantly different for
|
|
|
|
|
|
|
|
|
|
preschool-age children. Between surveys, the dental safety net was
|
|
|
|
|
|
|
|
|
|
expanded for youth but remained largely unchanged for adults.
|
|
|
|
|
|
|
|
|
|
Conclusions: Expanding the dental safety net for youth could have
|
|
|
|
|
|
|
|
|
|
contributed to increased access to dental care among children relative
|
|
|
|
|
|
|
|
|
|
to adults and contributed to the decrease in disparities in DU and UC
|
|
|
|
|
|
|
|
|
|
among youth. Knowledge Transfer Statement:Between 1999-2004 and
|
|
|
|
|
|
|
|
|
|
2011-2016, the dental safety net was expanded for youth but remained
|
|
|
|
|
|
|
|
|
|
largely unchanged for adults. Using national survey data to compare
|
|
|
|
|
|
|
|
|
|
changes in disparities in past-year dental use and untreated dental
|
|
|
|
|
|
|
|
|
|
caries by income between adults and youth sheds light on the potential
|
|
|
|
|
|
|
|
|
|
impact of expanding the dental safety net.'
