Introduction: there is evidence of a relationship between physical and cognitive activity and the development of dementia, although this hypothesis has not been tested in Mexican population.
Objective: analyze the association between an increased participation in physical and cognitive activities and the probability of having dementia, using a Mexican open population sample.
Materials And Methods: we made a cross sectional survey in open Mexican population of residents in urban and rural areas of 65 of age and older; we performed cognitive assessments to identify subjects with dementia, as well as questionnaires to assess the level of participation in physical and cognitive activities.
