title: Relation entre la mastication et la qualité de l'alimentation des aînés de l'Étude longitudinale québécoise sur la nutrition et le vieillissement (NuAge).
abstract: The objective of this study was to assess the relationship between the quality of mastication and dietary intake among community-dwelling older adults (67-84 years). A secondary analysis of data collected upon entry of participants in the NuAge study was effected. Perceived masticatory efficiency (n=1793) was measured using a questionnaire inspired by the Oral Health Impact Profile. Direct assessment of masticatory efficiency was carried out in a subsample (n=94), using a validated clinical test (Swallowing Threshold Test Index, 0-100%). Dietary intake was calculated from three non-consecutive 24h recalls. Mean scores indicate good perceived masticatory efficiency (Men:26.22±0.19/28;Women:25.81±0.21/28), but weak assessed efficiency (Men:60.8% [CI(57.3-64.2)]; Women:61.2% [CI(57.7-64.7)]). Multivariate regression analysis, adjusting for confounding variables (age, sex, schooling, living alone, income, smoking, chronic conditions, functional autonomy), showed that masticatory efficiency (measured or perceived) was not associated with intake of fruits/vegetables, protein, vitamin C or folic acid.
