Abstract

Abstract:Objective: chronic bronchitis may have a key influence on cognitive function, however, the relationship between chronic bronchitis and cognitive impairment in the elderly Chinese population has not been explored. The present study investigated the association between cognitive impairment and chronic bronchitis in elderly Chinese subjects over 90 years of age. Methods: This study comprised data from subjects included in the 2005 Project of Longevity and Ageing in Dujiangyan, China. Subjects were divided into two groups: cognitive impairment group and normal group. Chronic bronchitis data were collected and cognitive function was assessed in all subjects using the Mini-Mental State Examination. Data were presented as mean±standard deviation (SD) or number and percentage. All data were computerized for statistical analysis using the Statistical Package for Social Sciences (SPSS) software package, version 11.5 software program. Results: Data from 763 subjects (249 men, 514 women) were included. There was no statistically significant difference in history of chronic bronchitis between the two groups. Education level in the cognitive impairment group was significantly lower than in the normal group. Conclusions: chronic bronchitis were not related to cognitive impairment in elderly Chinese people over 90 years of age.
