ObjectiveTo assess whether short-term changes in income (IC) in adulthood were associated with self-rated oral health (SROH) and chewing difficulties (CD).
MethodsSecondary analysis of a longitudinal study in Florianopolis, Southern Brazil (EpiFloripa); a total of 1720 adults participated in 2009 and 1223 in 2012. Logistic regression analysed the variation of SROH and CD according to short-term changes in income (IC) groups (high income-stable', increased income', decreased income' and low income-stable') and adjusted for covariates (age, sex, marital status, skin colour, self-reported number of teeth and education).
ResultsAfter adjusting for covariates, participants in the decreased income' were more likely to have poor SROH and CD than those at the high income-stable' group (OR: 1.78, 95% CI: 1.23, 2.58; OR: 2.76, 95% CI: 1.61, 4.74, respectively). Significant differences were also found between the low income-stable' and high income-stable' groups, but these differences were explained when adjusted for potential confounders. There were no significant differences in SROH and CD between the increased income' and the high income-stable' groups.
ConclusionsOverall, SROH and CD were adversely influenced by negative changes in income during adulthood in a short period of 3 years.
