Few studies have been interested in the relationship between dietary patterns and activity limitation in older adults yet. We analysed the association between dietary patterns and the risk of self-reported activity limitation - that is mobility restriction, limitation in instrumental activities in daily living (IADL) and in activities in daily living (ADL) - in community-dwellers aged 67+ years initially free of activity limitation in 2001-2002 and re-examined at least once over 10 years - that is 583 participants for mobility restriction, 1114 for IADL limitation and 1267 for ADL limitation. At baseline, five sex-specific dietary clusters were derived by hybrid clustering method from weekly frequency of intake of twenty food and beverage items. Self-reported mobility restriction, limitations in IADL and in ADL were assessed using the Rosow-Breslau, the Lawton-Brody and the Katz scales, respectively. Associations between dietary clusters and the risk of each activity limitation were assessed using Cox proportional hazard models. In models adjusted for socio-demographic and health-related covariates, compared with the 'Healthy' cluster the 'Biscuits and snacking' cluster was associated with a higher risk of mobility restriction (hazard ratio (HR)=3·0; 95 % CI 1·6, 5·8) and limitation in IADL (HR=2·1; 95 % CI 1·1, 4·2) in men and limitation in ADL in women (HR=2·3; 95 % CI 1·3, 4·0). In this French cohort of community-dwellers aged 67+ years, some unhealthy dietary patterns may increase the risk of activity limitation all along the disablement process in older adults.
