[Detection of cognitive impairment in the population of persons older than 64 years: first phase of the Cuida'l project].
UNLABELLED: OBJECTIVE. To know the proportion of people with positive result in test. Design. Cross sectional study in 53 health centers. SETTING. Primary care. PARTICIPANTS: Aleatory sample of non-institutionalised, elder than 64 years patients attended in the 53 health centers. MEASUREMENTS VARIABLES: age, sex, civil status, and educational level. The detection of cognitive deterioration (CD) was carried out in primary care units with Folstein's Mini Mental Test (MMT) and the Isaacs Set-Test in case of illiteracy. Cut-off points 24 and 27 respectively. CD predictor variables analysis with logistic regression. MAIN RESULTS: The tests were applied to 4,467 individuals (56.1% females). There were found as possible cases of CD 399 patients (72.2% with MMSE). Positive percentage was 7.78% (95% CI, 5.69%-10.99%) in males and 9.45% (95% CI, 7.31%-12.43%) in female, adjusting with indirect method, according to the 1996 Catalonia list of inhabitants. Significant predictor factors were found with the multivariate analyses: primary educational level in front of illiteracy (OR=1.40, 95% CI, 1.13%-1.74%) and age-groups: 74-79 years, 75-79 years and y >= 80 years in front of <70 years old (OR=1,48, 95% CI, 1.02%-2.14%, OR=2.29; 95% CI, 1.60%-3.28% and OR=5,02; 95% CI, 3.59%-7.03% respectively). CONCLUSIONS: The cognitive deterioration prevalence increases with age and it is less frequent in individuals with higher studies Using MMSE and Set-Test we found several possible cases of cognitive deterioration in our population.
