To estimate the prevalence of generalized anxiety disorder (GAD) in elderly and to investigate the association with physical comorbidity, depression, daily habits.
426 subjects from the population-based Faenza Community Aging Study (De Ronchi et al 2005), mean age 85,1 (Standard Deviation = 6,9). The Geriatric Anxiety Inventory short-form (GAI-sf) was utilized to define GAD (score ≥ 3). Logistic-regression were used to estimated odds ratio and 95%Confidence Intervals (CI).
Subjects with anxiety were 84 (21,2%), 63,1% were women. For age < 80 the prevalence of GAD was 38,1% while for age> 95 was 4,8%. When we compared elderly with GAD to elderly not affected we found the following results: no hobbies (83,3% vs 79,6%) p = 0,124, no friendship (21,8% vs 15,8%) p = 0,425, they don’t make physical activity (53,7% vs 45,6%) p = 0,214 than subjects without anxiety. To have comorbidity was associated with anxiety: one disease OR (CI95%) = 2,71 (1,15–6,24), two or three OR (CI95%) = 2,57 (1,07–6,16) and > three OR (CI95%) = 7,5 (1,81–31,05). Hypertension was positively associated with anxiety OR (CI95%) = 1,94 (1,04-3,62). Depression was highly correlated with anxiety OR (CI 95%) = 5,82 (3,39–9,98). Moderate alcohol consumption was negative associated with anxiety OR(CI 95%) = 0,49 (0,25–0,95).
