None of the participants had a history of dementia diagnosis, and all the participants had a Mini\u2010Mental State Examination score of \u226524. Participants were evaluated for hand function using grip strength and snap fastener tests, and for cognitive function using the National Center for Geriatrics and Gerontology\u2010Functional Assessment Tool.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 72 participants (31.6%) were diagnosed with MCI. The slow snap fastener test group had a higher proportion of participants with MCI (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) and impairments in memory (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.010), attention (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.043), executive function (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001), and processing speed (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.044) compared to the fast snap fastener test group. The slow speed of fastening snap fasteners was significantly associated with MCI and impairment in memory, attention, executive function, and processing speed (MCI: adjusted odds ratio (AOR)\u00a0=\u00a03.88, 95% confidence interval (CI)\u00a0=\u00a01.64\u20139.19; memory: AOR\u00a0=\u00a05.73, 95% CI\u00a0=\u00a01.58\u201320.82; attention: AOR\u00a0=\u00a03.95, 95% CI\u00a0=\u00a01.10\u201314.11; executive function: AOR\u00a0=\u00a07.22, 95% CI\u00a0=\u00a01.78\u201329.24; processing speed: AOR\u00a0=\u00a07.52, 95% CI\u00a0=\u00a01.19\u201347.66) according to the multiple logistic regression analysis.
