The role of education on the association between disability and depressive symptoms among community-dwelling older adults: Evidence from Frailty in Brazilian Older People (Fibra) study.

OBJECTIVES

To explore whether higher socioeconomic status attenuates the effects of depressive symptoms on disability among older adults.

METHODS

We conducted a cross-sectional study based on 596 older adults, aged 65 and over, from a large city (Belo Horizonte) in Brazil. Disability was defined as limitation in activities such as Basic Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL). Covariates were age, comorbidities, Body Mass Index (BMI) and grip strength. Statistical analyses were based on Ordinal Logistic Regression and calculated separately for men and women.

RESULTS

Elderly women with disability and higher education levels have similar prevalence of depressive symptoms compared to those without disability (17.9% and 16.1%, respectively), but lower compared to those disabled with lower education (37.2%). A positive gradient trend was observed for depressive symptoms across disability categories among women (OR = 2.61; 95% CI 1.52, 4.48). However, these patterns were not observed among men.

CONCLUSION

A higher level of education attenuates odds of depressive symptoms in elderly women with disability but does not eliminate it. Therefore, screening for depressive symptoms in low-educated elderly women is important in order to identify them and start early prevention care for target risk population and decrease the disability expenses for health services.
