P8: Depression, diabetes, and healthcare services use – Brazilian Longitudinal Study of Aging (ELSI- Brazil, 2015-2016)

Abstract

Objectives: Low- and middle-income countries face increasing burden of noncommunicable chronic diseases due to rapid population aging. The Objectives of this study is to estimate the association of co-occurring depression and diabetes with healthcare services utilization in the Brazilian population aged 50 years andolder.

Methods: This is an analysis using baseline data of the ELSI-Brazil study. Measurements used were self-reported previous diagnosis for diabetes and a cut-off point of 4 on the CES-D-8 score for depression. Any medical consultations, specialist consultations and hospitalizations in the previous 12 months were assessed for measuring health services use. Logistic regression was used to estimate the association of having depression, diabetes, or both, compared to having none of the conditions with healthcare services utilization.

Results: In a final sample of 8303 participants, the adjusted odds ratios (95%CI) in the depression only group (27.9%), in the diabetes only group (9.7%), and in the depression and diabetes group (5.8%), for any medical consultations were 1.2 (1.01-1.42), 3.39 (2.4-4.79) and 3.12 (1.82-5.35); for specialist consultations, 1.05 (0.91-1.21), 1.34 (1.07-1.68) and 1.13 (0.86-1.49); and for hospitalizations, 1.42 (1.1-1.84), 1.42 (1.02-1.96) and 3.1 (2.12-4.54), respectively. All models were adjusted for sex, age, education, marital status, insufficient physical activity, current drinking and smoking, obesity and number of other diseases and conditions.

Conclusions: Those with diabetes seemed more likely to have any or specialized medical consultations. However, those with the depression and diabetes comorbidity were more likely than any other group to have been admitted to a hospital in the last year, which is distressing and costly. Screening for depression could be incorporated into diabetes usual care to reduce related complications and hospitalizations.
