N2 - Objective:To investigate the relationship between functional dentition (FD) and changes in dietary patterns (DPs) in older adults.DESIGN: This was a 12-month prospective study, with dental examinations at baseline and questionnaires at baseline and follow-up. Dentition was classified as FD (containing ≥10 occlusal contacts), non-FD with dentures and non-FD without dentures. A 154-item food frequency questionnaire assessed dietary intake in the previous month. Food items (servings/day) were combined into 22 food groups based on their similar nutrient profile, culinary use and previous studies in Thailand. DPs were identified through factor analysis of baseline intake and applied scores were used to estimate changes in DP scores. The association between baseline FD (exposure) and change in each DP score (outcome) was tested in linear regression models adjusting for baseline sociodemographic factors, behaviours, chronic conditions, medications, total energy intake and DP score.SETTING: Phetchaburi, Thailand.PARTICIPANTS: 788 community dwellers aged ≥ 60.RESULTS: 651 participants were retained after 12 months (82.6% retention rate), of whom 14.1% had FD. Having an FD was positively associated with larger increases in vegetable intake. Three DPs were identified. Participants with FD had larger increases in healthy (0.13; 95% CI: -0.13 to 0.39) and carbohydrate-rich diets intake (0.12; 95% CI: -0.17 to 0.40) as well as larger reductions in meat-rich diet intake (-0.12; 95% CI: -0.45 to 0.21) than those with neither FD nor dentures. However, these differences were not significant.CONCLUSION: There was little support for an association between baseline FD and changes in DPs.
