Background: A tool to assess cognitive function among community-dwelling older adults without cognitive testing is needed because regular cognitive assessments require considerable time and effort owing to the rapidly aging population. This study developed a screening model for the early detection of cognitive decline for use by community general support center staff and verify its accuracy.
Methods: We used a dataset from the IRIDE Cohort Study (data from five cohorts merged) and created two models. Age, sex, medical history, and lifestyle factors were included as variables in Model 1. Model 2 additionally included years of education. A binary logistic regression analysis was conducted using Mini-Mental State Examination (MMSE) scores as the objective variable. Subsequently, the integer scores of the coefficients were calculated to develop the final models.
Results: The analysis included 7,028 individuals (4,549 women, mean age = 74.8). Of the participants, 512 (7.3%) had MMSE scores below 24, indicating cognitive decline. In the final version of Model 1, the cutoff value was 4/5; sensitivity, 76.2%; and specificity, 63.1%, with an area under the receiver operating characteristic curve (AUC) of 0.774 (95% CI = 0.754–0.795). In the final version of Model 2, the cutoff value was 0/1; sensitivity, 76.6%; specificity, 68.7%; and AUC, 0.804 (95% CI = 0.786–0.823).
Conclusions: Both models had acceptable accuracy for detecting cognitive decline, but Model 2 was more accurate. Therefore, it is important for staff to ask respondents about their years of education.
