Association of depressive symptomology and psychological trauma with diabetes control among older American Indian women: Does social support matter?

AIMS: Among older American Indian women with type 2 diabetes (T2DM), we examined the association between mental health and T2DM control and if social support modifies the association.

METHODS: Survey data were linked to T2DM medical record information. Mental health measures were the Center for Epidemiologic Studies - Depression Scale and the National Anxiety Disorders Screening Day instrument. T2DM control was all HbA1c values taken post mental health measures.

RESULTS: There was not a significant association between depressive symptomatology and higher HbA1c although increased depressive symptomatology was associated with higher HbA1c values among participants with low social support. There was a significant association between psychological trauma and higher HbA1c values 12months [mean 7.5, 95% CI 7.0-8.0 for no trauma vs. mean 7.0, 95% CI 6.3-7.6 for trauma with no symptoms vs. mean 8.4, 95% CI 7.7-9.1 for trauma with ≥1 symptom(s)] and 6months later [mean 7.2, 95% CI 6.7-7.7 for no trauma vs. mean HbA1c 6.8, 95% CI 6.2-7.4 for trauma with no symptoms vs. mean 8.4, 95% CI 7.6-9.2 for trauma with ≥1 symptom(s)]. High social support attenuated the association between psychological trauma and HbA1c values.

CONCLUSIONS: T2DM programs may consider activities that would strengthen participants' social support and thereby building on an intrinsic community strength.
