We found that respondents with higher
household income, but not individuals
with more education, were less likely to
skip insulin injections they knew they
should take. This may reflect easier access to
medications and supplies among individuals with higher income, but it is also likely
that higher socioeconomic status is associated with more access to diabetes education, higher health literacy, greater control
over one’s daily routines, and better problem-solving skills (19). Our study appears
to be among the first to identify an association between socioeconomic status and insulin omission. Future research should seek
to identify potential mediators of this relationship, i.e., what links lower socioeconomic status to insulin omission.
