We conducted a cross-sectional study to assess the association of various
demographic and medical-care variables with metabolic outcomes in
non-insulin-dependent diabetic subjects. The study population was
representative of the diagnosed care-seeking diabetic population of a
defined geographic community on the Navajo reservation in Arizona. The
dependent variable metabolic control was measured as the mean of all random
plasma glucose values obtained only at scheduled diabetes clinic visits
over 2 yr. Multivariate analysis of the data showed that better metabolic
control was most strongly associated with compliance with scheduled
appointments. Mode of treatment was also associated with metabolic control.
Other variables tested, including source of care, age, sex, duration of
diabetes, presence of complications, and weight change, were not associated
with metabolic control. The strongest analysis of covariance model with
demographic and medical-care variables accounted for 39% of the variance in
metabolic control. The analysis suggests that other variables, possibly
including several psychosocial variables, need to be assessed for their
contribution to metabolic control.
