Objective: The objective of this study was to assess changes in social inequalities in healthcare utilization among people with diabetes between 2001 and 2007. Methods: The addresses of 9,868 and then 6,204 adults with diabetes, randomly selected from the Health Insurance databases for 2001 and 2007, respectively, were geocoded at the Iris level (an area of approximately 2,000 inhabitants). Changes in annual healthcare utilization were analyzed according to the Social Disadvantage Index (EDI), divided into quintiles ranging from the least disadvantaged (DEF-) to the most disadvantaged (DEF+), after adjusting for age, sex, antidiabetic treatment, and country of birth. An interaction term between the year and the EDI was introduced to study changes in the gradient. Results: DEF+ individuals were more often women, younger, and more often born abroad. In 2001, DEF+ individuals were less likely to have consulted an endocrinologist, an ophthalmologist, or a dentist, but had made more frequent use of a general practitioner (GP). They had been reimbursed for 3 glycated hemoglobin (HbA1c) tests and other recommended laboratory tests as often as DEF- individuals. Between 2001 and 2007, the frequency of long-term illness (ALD) coverage increased for all groups, but more so for DEF+, and most indicators of healthcare utilization improved, regardless of the level of social disadvantage. Consultations with an ophthalmologist were the only ones to have increased only among DEF-. No gradient had changed in a statistically significant way during this period, with the exception of the frequency of general practitioner (GP) visits, which had decreased among DEF-. Conclusion: While the impact of social inequalities on healthcare utilization remains significant regarding visits to healthcare professionals (with the exception of private endocrinologists), the gap between levels of social disadvantage appears stable or even narrowing, except for visits to ophthalmologists.
