A cognitive function predicted method by Useful Field of View tests among elder people in Beijing

Abstract

ObjectiveTo analyze the visual functions of the elder people in China by Useful Field of View (UFOV) to verify performances in Chinese elders. MethodsA total of 90 participants aged 60 years or above were recruited from residents in the Jiade Senior Apartment and the Fuchengmen Public Health Community in Beijing. Participants completed three tests, Mini Mental State Examination (MMSE), Digit Span test and UFOV. We also tested the digit span and UFOV the following year. ResultsThe correlation between age and MMSE score was significant (r = −0.422, P < .001). Digit Span scores showed significant negative relationships for all three subtests (P < .01) between ages. The scores of UFOV test 1 showed a non-significant correlation with age, r = 0.147, P > .1, while UFOV test 2 and UFOV test 3 showed significant positive relationships with ages, (both P < .01). Thirty-nine participants (out of 90) finished the digit span and UFOV the following year. Only UFOV test 3 has a significant differential performance between two years (t = −2.95, P < .01). We found UFOV tests showed the visual response capacity and had a strong correlation with ages (statistically significant). ConclusionUFOV could be an effective way to evaluate cognitive ability in Chinese elderly people and the selective-attention test of UFOV may be a more sensitive measurement.
