Abstract
En 中文
This study aims to investigate the factors associated with Mini Nutritional Assessment-Short Form (MNA-SF) scores and their relationship with health outcomes in community-dwelling older adults over a four-year follow-up. This longitudinal study involved older adults who received primary health care in Santana do Deserto, Brazil, from 2018/2019 to 2022/2023. Validated instruments were used to assess cognition (Mini-Mental State Examination-MMSE), functionality (Katz and Lawton), loneliness (UCLA), mental health (DASS-21), quality of life (WHOQOL), social support (SSQ-6), and nutritional status (MNA-SF). Multivariate linear and logistic regression models were employed to identify predictors of MNA-SF scores over four years and to evaluate its predictive value for various health outcomes. A total of 584 older adults completed both assessments (response rate: 87.4 %). Baseline factors such as older age, increased hospitalizations, poorer functionality, higher comorbidity burden (number of self-reported diagnosed diseases), and lower social support were associated with lower MNA-SF scores at follow-up. Nevertheless, baseline MNA-SF scores only significantly predicted follow-up MNA-SF scores and environmental quality of life. This study emphasizes the significance of identifying malnutrition risk with the MNA-SF and acknowledges various factors affecting nutritional status in older adults. However, its restricted predictive value for long-term health outcomes indicates the need for careful use when forecasting future health outcomes in low-and middle-income settings.
