All values are given as mean ± standard deviation except for gender, medications, and diabetes diagnosis, which are given in actual numbers.
a
Numbers are the same for all metabolic and medication variables; diabetes diagnosis data available for 121 caregivers and 114 controls.
b
p = .052; all other comparisons were p > .05.
HOMA-IR = homeostatic model of insulin resistance; HDL = high-density lipoprotein.
