Tooth loss, diet quality, and cognitive decline: A 15-year longitudinal study.

ABSTRACT:

Objectives

To investigate the association between tooth loss and the incidence of mild cognitive impairment (MCI) and dementia, focusing on diet quality as a potential mediator.

Design

Prospective cohort study.

Setting and participants

Community-dwelling older men enrolled in the Northern Ireland PRIME study (Prospective Epidemiological Study of Myocardial Infarction).

Measurements

A group of men, aged 58-71 years, underwent dental examinations in 2001-2003. Surviving participants were invited to attend a cognitive rescreening in 2016-2020, which included a food frequency questionnaire. Cognitive outcomes were categorised as normal, MCI or dementia, based on standardised neurocognitive tests. Dietary diversity scores (DDS) were calculated based on the frequency
