Methods One hundred and one senile dementia patients were divided into two groups with 53 cases in experimental group receiving targeted rehabilitation training besides routine nursing and 48 in control group only receiving routine nursing.Self-care ability of patients in the two groups was comparatively evaluated according to the activity of daily living scale (ADL).Result The ADL score and the total score of the experimental group were both higher than those of the control group (P<0.05).Conclusion Rehabilitation training according to the specific conditions of patients with senile dementia can improve their self-care ability in adapting to the society, delaying the progress of the disease and improving the quality of life.

Objective To translate the Eating Behavior Scale (EBS) into Chinese and test its reliability and validity. Methods The Chinese Version of the scale (C-EBS) was developed through translation, back-translation, cross-cultural adaption and pre-test. A convenient sample of 100 old people with dementia was investigated with C-EBS to test its reliability and validity. Results The Cronbach′s α, Guttman Spilt and test-retest reliability of C-EBS were 0.842, 0.865 and 0.840, respectively. The I-CVIand S-CVI of C-EBS were 1.00, and the score of C-EBS was negatively correlated to the total score of The Chinese Edinburgh Feeding Evaluation in Dementia scale(C-EdFED) (r = 0.727,P < 0.01). Conclusion The C-EBS is reliable and valid and can be used as a valid tool to measure the eating ability among the old people with dementia in China.

Objective: To analyze the association between non-school sedentary time and myopia among primary and secondary school students with different levels of physical activity, so as to provide data for precise measures to prevent and control myopia. Methods: From September to December 2019, stratified cluster sampling was used to select 7 872 primary and secondary students in grades 4 to 12, middle and high school students from Hefei, Suzhou, Chizhou and Wuhu Cities in Anhui Province. Face-to-face questionnaires and vision examinations were conducted to collect demographic information, physical activity time, sedentary study time and visual health status. Potential categories were analyzed for different types of physical activity time, and Logistic regression was used to assess the relationship between non-school sedentary time and myopia at different levels of physical activity. Results: A total of 2 976 primary and secondary school students were found with high physical activity levels and 4 896 primary and secondary school students with low physical activity levels. The proportion of low physical activity was higher in girls than in boys (68.7% vs . 55.6%), and the differences were statistically significant ( χ 2=143.97, P <0.01). The overall screening myopia rate was 48.2%, with statistically significant differences among female students (53.0%) compared with male students (43.3%), urban students ( 51.8 %) compared with rural students (44.5%), and longer non-school sedentary time students (60.6%) compared with average (45.1%) and shorter (42.1%) non-school sedentary time students, and the differences were statistically significant ( χ 2=73.15, 41.96 , 161.74, P <0.01). Adjusting for confounders such as residence, grade, gender, age, father s education, mother s education, and body mass index (BMI), multivariate Logistic regression analysis revealed that prolonged after-school sedentary study was positivety correlated with myopia among primary and secondary school students of low physical activity levels ( OR=1.52, 95%CI=1.27-1.83, P <0.01), and there was no statistical association between after-school sedentary time and myopia in primary and secondary school students with high physical activity levels ( P >0.05). Conclusion Attention should be paid to non-school sedentary time for primary and secondary school students with low physical activity levels. And students who spend a lot of time sitting outside of school should be encouraged to maintain high physical activity levels to reduce the risk of myopia.

Objective:To explore the current status of intrinsic capacity in elderly patients with hospitalization-associated disability (HAD) and explore its influencing factors.Methods:From November 2023 to January 2024, convenience sampling was used to select 203 elderly patients with HAD at Xuanwu Hospital of Capital Medical University as the study subjects. A survey was conducted on elderly patients using the General Information Questionnaire, Fried Frailty Phenotype, Barthel Index, Social Support Rating Scale, and Intrinsic Capacity Assessment Tool. Binomial Logistic regression was used to analyze the influencing factors of intrinsic capacity in elderly patients with HAD.Results:A total of 203 questionnaires were distributed, and 199 valid questionnaires were collected, with a valid response rate of 98.03% (199/203). The total score of intrinsic capacity in 199 elderly patients with HAD was 5.00 (4.00, 6.00), with scores for cognitive dimension, psychological dimension, motor dimension, vitality dimension, and sensory dimension being 1.00 (1.00, 2.00), 2.00 (1.00, 2.00), 0 (0, 1.00), 1.00 (1.00, 1.00) and 1.00 (1.00, 1.00), respectively. The binomial Logistic regression showed that department of medicine and surgery, self-rating health status, social support, serum albumin, and Barthel Index were the influencing factors of intrinsic capacity in elderly patients with HAD ( P<0.05) . Conclusions:The intrinsic capacity of elderly patients with HAD is at medium to low level, with the most severe impairment in the motor dimension. Medical and nursing staff should develop personalized rehabilitation measures for elderly HAD patients based on the influencing factors of their intrinsic capacity, enhance their intrinsic capacity, and reduce the burden of care on families and society.

Objective:To explore the current situation of ageism among older adults in megacity communities and analyze its influencing factors.Methods:From November to December 2023, convenience sampling was used to select 200 older adults who visited the Niujie Community Health Service Center in Xicheng District, Beijing as the research subject. A survey was conducted on older adults using the General Information Questionnaire, Barthel Index, 15-Item Geriatric Depression Scale, Family Adaptation, Partnership, Growth, Affection and Resolve Scale (Family APGAR Scale), Rosenberg Self-Esteem Scale, Social Support Rating Scale, Lubben Social Network Scale, and Ageism Questionnaire. Multiple linear regression was used to analyze the influencing factors of ageism among older adults in the community.Results:A total of 200 questionnaires were distributed and 200 valid questionnaires were collected, with a valid response rate of 100.00% (200/200). The total score of ageism among 200 older adults in the community was (3.55±0.31), with objective and subjective scores of (3.59±0.28) and (3.50±0.48), respectively. Multiple linear regression showed that occupational status, pre-retirement or current work, family care, self-esteem, and social support were the influencing factors of ageism among older adults in the community ( P<0.05) . Conclusions:Ageism among older adults is influenced by various factors. Medical and nursing staff should focus on older adults who are retired, mainly engaged in physical work, and have poor family and social support when formulating intervention strategies. Community health workers should regularly organize activities to encourage older adults to actively participate, enhance their sense of social participation, reduce ageism, so as to promote healthy aging.

Objective: To explore the association of vitamin D deficiency with anxiety and depressive symptoms as well as their comorbidity, so as to provide references for improving the mental health of children and adolescents. Methods: From October to December 2021, a total of 1 323 students from four middle schools in Shenzhen were selected by using convenience sampling method for a questionnaire survey and physical examination. Fasting blood samples were collected to detect vitamin D levels. The Chi square test and multiple Logistic regression model were used to analyze the association of vitamin D deficiency with anxiety and depressive symptoms and their comorbidity among middle school students. Results: The detection rates of anxiety, depressive, and thier comorbidities in middle school students were 33.0%, 21.5% and 16.3%, respectively. After adjusting for confounding factors, vitamin D deficiency was positively associated with the risk of anxiety symptoms ( OR=1.59, 95%CI =1.02-2.46), depressive symptoms ( OR=1.94, 95%CI =1.22-3.09) and anxiety depressive comorbid symptoms ( OR=1.75, 95%CI =1.06-2.90) in secondary school students ( P ＜0.05). Conclusion Vitamin D deficiency is associated with an increased risk of anxiety, depressive and their co morbidity symptoms in middle school students, and the directionality of the association should be further studied.

Objective:To evaluate the relationship between preoperative serum bilirubin concentrations and postoperative delirium (POD) in the patients undergoing knee or hip replacement.Methods:Medical records from 413 patients undergoing knee or hip arthroplasty were selected from August 2020 to October 2023 at Qingdao Municipal Hospital using a nested case-control design based on the PNDABLE study cohort. The patients were divided into POD group ( n=77) and non-POD group ( n=336) according to whether POD occurred. Univariate analysis was used to analyze the influencing factors. Logistic regression was used to identify the risk factors for POD. The significance of mediation effect was tested. The receiver operating characteristic curve was drawn to evaluate the accuracy of risk factors in predicting POD. Results:There were significant differences in age, education time, ratio of diabetes history, Memorial Delirium Assessment Scale score, total bilirubin concentration, direct bilirubin concentration, indirect bilirubin concentration, Aβ 42 concentration, p-tau concentration, t-tau concentration, Aβ 42/p-tau ratio and Aβ 42/t-tau ratio between POD group and non-POD group ( P<0.05). The results of logistic regression analysis showed that preoperative serum total bilirubin, direct bilirubin and indirect bilirubin were risk factors for POD ( P<0.05). The results of mediation effects showed that the concentration of total tau protein in CSF partly mediated the relationship between high serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and POD. The area under the receiver operating characteristic curve of total bilirubin, direct bilirubin and indirect bilirubin combined with CSF biomarker concentrations in predicting POD was 0.83 ( P<0.001). Conclusions:Preoperative elevated concentrations of total bilirubin, direct bilirubin and indirect bilirubin are risk factors for POD in the patients undergoing knee or hip replacement. CSF t-tau concentration has a partly mediating role in the association between serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and the development of POD.

Objective: To explore two visual acuity standards for examining uncorrected visual acuity (UCVA) to define poor vision in lower grade elementary school students, and to compare the difference of screening myopia rates when combined with non cycloplegic auto refraction (NCAR), so as to provide a scientific basis for standardizing UCVA examination methods using CAR as the gold standard of authenticity and reliability. Methods: From March 22nd to April 9th, 2023, a total of 549 first and second grade students aged 7-8 years from a primary school in Hefei City were selected for the study by convenient cluster sampling method. Two methods were employed for UCVA examination:the first method involved charts where the student could not make mistakes in identifying at least half of the characters per line (V1), and the second method used charts with character sizes ranging from 4.0 -4.5, 4.6-5.0 and 5.1-5.3, without allowing 1, 2 and 3 errors per line (V2). While NCAR was performed, then 187 students underwent CAR examination. Paired Wilcoxon rank-sum test and McNemar test were used to compare the differences between V1 and V2 methods in defining poor vision and screening myopia rates. Using CAR as the gold standard, the authenticity and reliability of defining screening myopia rates through the combination of V1 and V2 methods along with NCAR were evaluated. Results: The UCVA examination results for V1 and V2 showed statistically significant differences in both the right eye [5.0(4.9,5.0), 4.9(4.8,5.0)] and the left eye [ 5.0 (4.9,5.0), 4.9(4.8,5.0)] ( Z=-13.95, -13.34, P <0.01). The detection rates of poor vision for the right eye were 43.53% for V1 and 63.21% for V2, and the left eye with 44.08% for V1 and 62.11% for V2, with statistically significant differences ( χ 2= 106.01 , 95.09, P <0.01). When screening myopia rates were assessed for UCNA methods combined with NCAR, the right eye rates were 21.49% for V1 and 24.59% for V2, and the left eye rates were 21.31% for V1 and 23.13% for V2, with statistically significant differences ( χ 2=15.06, 8.10, P <0.01). Using CAR as the gold standard, the detection rates in the right eye and left eye were 16.58 % and 17.11%, respectively. The Youden indices for defining screening myopia in the right eye were 0.80 for V1 and 0.79 for V2, and the left eye with 0.85 for V1 and 0.83 for V2. The agreement rates for the right eye were 91.98 % for V1 and 89.30% for V2, and the left eye with 94.12% for V1 and 91.98% for V2. The Kappa values for the right eye were 0.73 for V1 and 0.67 for V2, and the left eye with 0.81 for V1 and 0.75 for V2. Conclusions Authenticity and reliability of two UCVA examination methods combined with NCAR in defining screening myopia are higher in V1 than V2 methods. It is recommended to unify the visual acuity examination methods by requiring the correct identification of more than half of the total number of visual markers in a row.
