| Objective:(1)To understand the status quo of cognitive function of the elderly in pension institutions,and analyze the correlation between the characteristics of different demographic data and cognitive function.(2)Explore the effects of mobile Internet APP use training on the cognitive function,positive and negative emotions of the elderly in nursing institutions.Methods:(1)Cross-sectional study: From May 2019 to November 2019,the elderly in a pension institution in a city were selected as the research objects.293 elderly people aged ≥60 and meeting the eligibility criteria in the institution were selected.The basic information,Internet use and cognitive function of the elderly were investigated by using a self-made questionnaire for the general situation of the elderly in nursing institutions and the Montreal Cognitive Assessment Scale(Mo CA).(2)Randomized controlled intervention study: On the basis of cross-sectional investigation,120 elderly people who met the criteria of acceptance and arrangement were selected as research objects and divided into control group and experimental group by random number table method,60 in each group.The control group received pension services from pension institutions and completed daily activities of pension institutions.The experimental group adopted Internet use intervention on the basis of the control group.The intervention lasted for 24 weeks.The first 12 weeks is the learning period,and the training on the use of commonly used mobile Internet apps is conducted.In the last 12 weeks,users can use the Internet for social networking,shopping,travel,study and other online activities as required,and gradually form the habit of using the Internet.Montreal Cognitive Assessment Scale(Mo CA)and Positive and negative Affective Scale(PANAS)were used to assess the cognitive function and emotional changes of the two groups before intervention and at the end of intervention 24 weeks.SPSS22.0statistical software was used to establish the database.Measurement data:normal distribution data were described with mean ± standard deviation.T-test or analysis of variance and multi-factor logistics analysis were used to analyze influencing factors.Non-normal distribution data were described by median and quartile spacing.Mann-whitney U rank-sum test was used for comparison between multiple groups,and P<0.05 indicated statistically significant differences.Counting data: frequency and percentage were used to describe,chi-square test was used for comparison between multiple groups,and P<0.05 indicated statistically significant differences.Results:(1)In this study,293 elderly people in nursing institutions were included for cognitive function evaluation,and the mean Mo CA score of elderly people was 21.90±3.45.The cognitive function of the elderly was correlated with age(F=17.129,P=0.000),education level(F=34.923,P=0.000),occupation before retirement(F=2.738,P=0.044)and number of children(F=3.829,P=0.010),and the differences were statistically significant.(2)After intervention,there was no significant difference in the total Mo CA score of cognitive function between the two groups(P >0.05),but the Mo CA score of the elderly in the experimental group showed significant differences in attention and concentration(Z=2.078,P=0.038),directivity(Z=2.019,P=0.043),delayed memory(Z=1.999,P=0.046)were significantly higher than the control group,and the differences were statistically significant.(3)After intervention,the Mo CA scores of the experimental group with junior high school education(Z=-2.068,P=0.039)and 70-79 years old(Z=-2.084,P=0.037)were significantly higher than the control group,and the difference was statistically significant.(4)After intervention,the scores of excitement(Z=-2.125,P=0.031),pride(Z=-2.055,P=0.040)and inspiration(Z=-2.091,P=0.037)on the positive emotion scale were all higher than those of the control group,and the differences were statistically significant.The scores of fear(Z=-2.066,P=0.039),hostility(Z=-2.231,P=0.026),sadness(Z=-2.129,P=0.033)and fear(Z=-2.319,P=0.021)were lower than those of the control group,and the differences were statistically significant.Conclusion:(1)The level of education of junior middle school and below and the cognitive function of the elderly over 70 years old were lower.(2)The training of using commonly used mobile Internet apps can improve the cognitive functions of attention and concentration,orientation and memory of the elderly aged 60-79 with Mo CA > 18 in nursing institutions to a certain extent.(3)The training of using commonly used apps on mobile Internet can improve the cognitive function of the elderly aged 70-79 years old and the education level of junior middle school and below in pension institutions to a certain extent.(4)Under the condition that the intervention methods remain unchanged and the number of interventions is increased,the training on the use of commonly used mobile Internet apps can effectively improve the cognitive function of the 70-79 year old elderly people in pension institutions.(5)The training of using commonly used mobile Internet apps can promote the positive emotions of the elderly in pension institutions,while reducing their negative emotions. |
