RESUMEN
AIM: To examine the prevalence and correlates of mild cognitive impairment in adults aged over 50 years attending primary care centers with complaints of cognitive failure. METHODS: A sample of 689 individuals aged ≥ 50 years with no previous diagnosis of dementia was assessed by use of the Mini-Mental State Examination, the Cambridge Cognitive Examination-Revised and the California Verbal Learning Test--to evaluate the mild cognitive impairment as dependent variables--and administration of a questionnaire on cognitive complaints and other instruments--to measure correlates. RESULTS: The prevalence of mild cognitive impairment was 31.40%, and positive associations were found for age, occupation, subjective memory complaints, reading habits and level of vocabulary. In the logistic regression, modeled mild cognitive impairment was associated with age (70 years or older), subjective cognitive complaints and level of vocabulary. CONCLUSION: Almost one-third of the adults aged ≥ 50 years attending primary care centers with subjective cognitive complaints were affected by mild cognitive impairment. Early evaluation of cognitive functioning is essential to establish adequate preventive and intervention strategies.

AIMS: To examine the prevalence and correlates of cognitive impairment (CI) in adults over 50 years old attending primary care centres with complaints of memory failure. METHODS: A sample of 580 individuals aged 50+ years with no previous diagnosis of dementia was assessed by use of the Mini Mental State Examination, the Cambridge Cognitive Assessment-Revised and the California Verbal Learning Test - to evaluate CI-dependent variables - and administration of a questionnaire on memory complaints and other instruments - to measure correlates. RESULTS: The prevalence of CI was 46.20% and positive associations were found for age, gender, level of education, subjective memory complaints, instrumental activities of daily living, reading habits and frequency of leisure activities. In the logistic regression, modelled CI was associated with older age, gender (49.12% women, 39.66% men), instrumental activities of daily living, and reading habits. CONCLUSION: Almost half of the adults aged 50+ years attending primary care centres with subjective memory complaints were affected by CI. Early evaluation of cognitive functioning is essential to establish adequate preventive and intervention strategies.
