Abstract:OBJECTIVE To investigate the knowledge of the aged who were recorded in Shanghai Pudong New Area and the impact of the diabetic mellitus and hypertension on the awareness of the related knowledge of dementia after education. METHODS A self-designed questionnaire was used to investigate the knowledge rate of Alzheimer’s disease in 942 recorded MCI in 2016. All the participants were divided and compared the awareness of knowledge according to the chronic disease, drug compliance and physical exercise. RESULTS The community MCI participants had the highest awareness of the concept of dementia, followed by risk factors, hazards and medical information. The rates of the awareness of the total scores, risk factors of dementia and medical treatment information, were higher in MCI+DM group than those of MCI+HB group.The awareness of the drug-compliance group were higher than those in the no compliance group, while that of the regular physical exercise group were higher than that of no regular physical exercise group, and the differences were statistically significant(P＜0.05 or P＜0.01). The regression analysis showed that the awareness rate of dementia was negatively correlated with age, and positively related to physical exercise, and the difference was statistically significant (P＜0.01). CONCLUSION The concept of dementia-related knowledge was the highest, followed by the risk factors, the hazard, and the medical information. That meant that the community health education work needed to be further strengthened in order to achieve early diagnosis and intervention.
