ABSTRACT
BACKGROUND: Subjective memory complaints (SMC) are commonly studied in older adults and have been identified as potentially prodromal to dementia and Alzheimer's disease. Studies among younger adults from South America are lacking. OBJECTIVE: To estimate the prevalence of SMC and the factors associated with it among Maule Cohort (MAUCO) participants. METHODS: We performed a cross-sectional analysis to estimate the prevalence of SMC and investigated its associated factors from MAUCO baseline data (Nâ=â6,687). Within groups defined by age (38-59, 60-74) and global cognition (Mini-Mental State Examination: ≥26, 25-22, ≤21), multinomial logistic regression models evaluated risk factors for SMC (Yes, Sometimes, No). RESULTS: Overall, SMC prevalence was 16.4%; 15.9% (95% CI 14.9-16.9%) among younger and 17.6% (15.8-19.4%) among older participants. Female sex, comorbidities, and bad/fair self-reported health status (SRHS) were generally associated with higher odds of SMC. CONCLUSION: Overall prevalence of SMC was 16%. Different factors were associated with the odds of SMC depending on age and global cognitive status. Future SMC studies should include sex-specific assessments, evaluate SRHS as a moderator of SMC reporting, and the influence of the SARS-CoV-2 pandemic on SMC reporting.

Prevalence of subjective memory complaints (SMC) in elderly community dwellers (ECD) ranges from 25 to 50%. Some controversy exists over the association between SMC and cognitive status. Objective: We investigated whether a correlation in cognitive performance existed between two different groups according to SMC. Methods: The Mini Mental State Examination (MMSE) and Dementia Rating Scale-Mattis (DRS-Mattis) were applied to two groups: ECD (n=14) with SMC and residents (n=14) of a long-term care facility (LTCF) without SMC. Results: The median age in the ECD group was 81.0 years, and in the LTCF group was 75.0 years. There was a statistically significant difference (p=0.048) between these groups regarding age. Concerning schooling (1-8 or ?9 years), there was no statistically significant difference between the groups (p=0.638). No statistically significant difference between the two groups was found for scores on the cognitive tests. Conclusion: SMC might be related to extrinsic factors other than insipient cognitive decline.
A prevalência de queixa subjetiva de memória (QSM) em idosos da comunidade (IRC) varia de 25-50%. Controvérsias existem a respeito da associação entre QSM e cognição. Objetivos: Foi investigado se há correlação entre QSM e declínio cognitivo em dois diferentes grupos. Método: Foi aplicado o Mini Exame do Estado Mental (MEEM) e a Escala de Avaliação de Demência Mattis (DRS-Mattis) em dois grupos de idosos: IRC (n=14) que apresentaram QSM e residentes (n=14) de uma instituição de longa permanência (ILP) sem QSM. Resultados: A mediana de idade do grupo ?IRC? foi de 81,0 anos e a do grupo ?ILP? foi de 75,0. Houve diferença estatisticamente significante (p=0,048) entre eles, considerando a idade. Não houve esta diferença (p=0,638) na distribuição dos indivíduos quando analisada a escolaridade (1-8 ou ?9 anos). Considerando-se os escores dos instrumentos cognitivos, não houve diferença estatisticamente significante entre grupos. Conclusões: QSM pode estar relacionada a outros fatores em idosos, e não somente à presença de declínio cognitivo.

RESULTADOS: A mediana de idade do grupo "IRC" foi de 81,0 anos e a do grupo "ILP" foi de 75,0. Houve diferenca estatisticamente significante (p=0,048) entre eles, considerando a idade. Nao houve esta diferenca (p=0,638) na distribuicao dos individuos quando analisada a escolaridade (1-8 ou ≥9 anos). Considerando-se os escores dos instrumentos cognitivos, nao houve diferenca estatisticamente significante entre grupos. CONCLUSÕES: QSM pode estar relacionada a outros fatores em idosos, e nao somente a presenca de declinio cognitivo.
