MCI and global cognitive impairment (GCI) were assessed using the Mini\u2010Mental State Examination and National Center for Geriatrics and Gerontology\u2010Functional Assessment Tool, which are multicomponent neurocognitive tests that include memory attention, executive function and processing speed. Dietary diversity was assessed using the diet variety score. The diet variety score assessed the 1\u2010week consumption frequency of 10 food groups, and either 0 or 1\u2009point was allocated to each category based on the following responses: (i) \u201ceat almost every day\u201d (1\u2009point); and (ii) \u201cnot eaten almost daily\u201d (0\u2009points).

The proportion of patients with a high dietary diversity was 69.9% (n\u2009=\u20096286). Multinomial logistic regression analysis revealed high dietary diversity was associated with MCI (OR 0.83, 95% CI 0.73\u20130.94) and GCI (OR 0.77, 95% CI 0.65\u20130.92) after adjusting for
