In the total sample of 1902, 4.7% (n=90) failed MRI due to claustrophobia. Out of the 90 who failed MRI, 24.4% (n=22) performed below the screening criteria for possible cognitive impairment compared to 18% (n=340) of the whole cohort. After adjusting for age, gender, education, physical function and abdominal waist circumference, subjects with claustrophobia did significantly worse on the screening tests than those who completed the MRI (odds ratio = 2.1; 95% confidence interval, 1.2-3.8; p=0.008) (Figure 1-2).
Fig.: Figure 1. The interval plot describes the association of claustrophobia prevalence (%) with possible cognitive impairment and the level of education. After adjusting for the level of education, subjects with claustrophobia did significantly worse on the screening test for subjects with possible cognitive impairment compared to those without claustrophobia. Claustrophobia prevalence among possibly cognitively impaired subjects increases with increased education.
Fig.: Figure 2. The interval plot describes the association of claustrophobia prevalence (%) with abdominal waist circumference (quartiles) – claustrophobia prevalence increases with increased abdominal waist circumference.
