Author/Year	Study Design	Objective	Number of Participants	Sample population	Setting	Impact on Outcome
Geraghty, 2010 (45)	Geographic information systems (GIS) software	To use GIS to expand understanding of disparities in health outcomes in within a community	7288	Individuals who had been diagnosed with type 2 diabetes and had been seen by a family physician or internist from April 2008-April 2009 at the University of California Davis Health System who had addresses on file	N/A	Women had higher HbA1c levels, being Black was predictive of having a higher HbA1c, patients who were seen in a primary care network were more likely to have lower HbA1c than those seen at a medical center; Patients were less likely to have a controlled LDL level if they had a higher HbA1c (OR 1.07 95% CI 1.04-1.11)
Seligman, 2011 (81)	Cross-sectional and chart review	To determine whether food insecurity is associated with poor glycemic control and whether this association is mediated by difficulty following a healthy diet, diabetes self-efficacy, or emotional distress related to diabetes	711	Patients with type 2 diabetes in the San Francisco Bay area or Chicago	Federally qualified health centers or affiliated with a public safety net health system	Those who were food insecure were more likely (OR 1.48, 95% CI 1.07-20.4) to have poor glycemic control (A1c ≥ 8.5%)
Gary-Webb, 2011 (44)	Cross-sectional	Evaluate relationship between neighborhood-level SES and health status and depression	1010	Participants from Look AHEAD trial of long-term weight loss among adults with type 2 diabetes	Clinical sites in Baltimore, Philadelphia, Pittsburgh and New York	Lower neighborhood SES was significantly associated with poorer health status (−1.90 physical health, −2.92 mental health, −2.77 composite score)
