VOLZ, Pâmela et al. Incidence of depression in the elderly and associated factor: systematic review. Psic., Saúde & Doenças [online]. 2020, vol.21, n.3, pp.851-864.  Epub Dec 31, 2020. ISSN 1645-0086.  https://doi.org/10.15309/20psd210326.

To characterize the incidence of depression in the elderly in longitudinal studies, with emphasis on the quantification of causal relationships between the risk factors and the onset of the disease. Literature systematic review, with no restriction of dates and languages. Were included observational longitudinal and community-based studies, performed with the elderly and that used instruments to measure depression. Were found 3.395 articles after excluding duplication, and 20 were selected for review after process of reading and evaluating according inclusion and exclusion criteria. Among the cumulative incidence studies, the measures ranged from 1.4% to 30.6% and, among the studies that measured incidence density, rates ranged from 16.4/1000 person-years to 141 / 1000 person-years. The variability may be associated to the different methodologies and instruments used, the different socio-political and economic contexts in which the studies were developed and the heterogeneity of the sample. The studies indicated a significantly higher probability of depression in female elderly, older, with a low level of education, a low socioeconomic level, a compromised social network, chronic morbidity and multimorbidity, with cognitive impairment, functional disability, risky alcohol consumption and sedentary lifestyle. Variation in incidence rates of cases of depression and depressive symptoms can be attributed to different instruments used, follow-up time and cultural contexts. Comprehensive longitudinal health care, which should be dispensed to the population, especially in basic care, could identify early and prevent the worsening of depressive symptoms in the elderly.
