OBJECTIVES: i) To investigate studies published between 1991 and 2010 on the prevalence of depressive morbidity (major depressive disorder [MDD], dysthymia and clinically significant depressive symptoms [CSDS]) among elderly Brazilians assisted at healthcare facilities; ii) to establish the prevalence of depression and identify its related factors; and iii) to conduct a meta-analysis to assess the prevalence of depressive syndrome among elderly individuals assisted or hospitalized at healthcare facilities. METHODS: Studies were selected from articles dated between January 1991 and June 2010 and extracted from the MEDLINE, LILACS, and SciELO databases. RESULTS: The final analysis consisted of 15 studies, distributed as follows: i) four sampled hospitalized patients, totaling 299 individuals, and found a prevalence of CSDS varying between 20 and 57% [corrected]; ii) four sampled outpatients, totaling 1,454 individuals; the prevalence of CSDS varied between 28 and 45% [corrected], and the prevalence of MDD varied between 23 and 42%; and iii) seven sampled elderly individuals residing in long-term care facilities (LTCF), totaling 839 individuals, and the prevalence of CSDS varied between 11 and 65%. CONCLUSION: The present review indicated a higher prevalence of both MDD and CSDS among elderly Brazilians assisted at healthcare facilities.
