UnlabelledOBJECTIVE. To know the proportion of people with positive result in test. Design. Cross sectional study in 53 health centers. SETTING. Primary care.ParticipantsAleatory sample of non-institutionalised, elder than 64 years patients attended in the 53 health centers.Variablesage, 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 ResultsThe 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).ConclusionsThe 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.
