title: Control of diabetes and fibrinogen levels as well as improvement in health care might delay low cognitive performance in societies aging progressively.
abstract: OBJECTIVE
  To know the prevalence and factors associated to low cognitive performance in a representative sample of the adult population in a society aging progressively.
  
  
  METHODS
  Cross-sectional population-based study carried out in a three-stage sampling: 81 census tracts (primary sampling unity) were randomly selected, followed by 1,672 households and 2,471 participants (weighted sample) corresponding to the second and third stages, respectively. The outcome prevalence was calculated according sociodemographic, behavioral and health related variables. Crude and adjusted prevalence ratios were estimated using Poisson regression.
  
  
  RESULTS
  The prevalence of low cognitive performance was high, mainly among females, and indicated linear trends into categories of age, schooling, income, plasma fibrinogen and self-reported health status. In multivariate models, gender, diabetes, fibrinogen and self-reported health status presented positive associations, while schooling, employment and sitting time presented negative associations with the outcome.
  
  
  CONCLUSIONS
  Interventions related to diabetes and fibrinogen levels control as well as improvement in health care might delay low cognitive performance in societies aging progressively as such the study population.
