Objective To explore the relationship between sleep disorders and dysmnesia of the elder people in the community of Tangshan and toprovide basis for effective intervention.Methods Totally 805 elder people in a community were evaluated with Pittsburgh Sleep Quality Index (PSQI) and Rivermead-IIMemory Test(RBMT-Ⅱ) and 150 elders with both sleep disorder and dysmnesia were divided into three groups:the control,the memory intervention,and the sleep+memory intervention group.The surveys among the elder people were carried out 3 and 6 months after the initial evaluation.Results Among 753 eligible elder people,263 had sleep disorders with an incidence rate of 31.3% and 583(77.4%) had dysmnesia.There was a significant correlation between sleep disorder and dysmnesia.Three months after the intervention,7 memory scores in the memory intervention group were miproved significantly (P < 0.01 or P < 0.05),as well as 9 memory scores and sleep quality in the sleep+memory intervention group and the scores of the story recalling (instantly) and the sleeping in the sleep+memory in tervention group were better than those of in the memory intervention group compared to the control group.Compared to those of the control group,9 memory scores were improved significantly (P < 0.01 or P < 0.05) in the memory intervention group,as well as 12 memory scores and sleep quality in the sleep+memory intervention group 6 months after the intervention.Compared to those of memory intervention group,story recalling (instantly),story recalling(delayed),name recalling,and the conscore were improved significantly (P < 0.01 or P < 0.05) in the sleep+memory intervention group.Conclusion The occurrence of dysmnesia in elder people maybe influenced by sleep quality.Memory training can improve memory,while the sleep intervention combined with memory training ismore effective for the miprovement of memory among the elderly.
