Construction and validation of a risk prediction model for depressive symptoms in a middle-aged and elderly arthritis population

BACKGROUND Arthritis is a prevalent and debilitating condition that affects a significant proportion of middle-aged and older adults worldwide.Characterized by chronic pain,inflammation,and joint dysfunction,arthritis can severely impact physical function,quality of life,and mental health.The overall burden of arthritis is further compounded in this population due to its frequent association with depression.As the global population both the prevalence and severity of arthritis are anticipated to increase.AIM To investigate depressive symptoms in the middle-aged and elderly arthritic population in China,a risk prediction model was constructed,and its effectiveness was validated.METHODS Using the China Health and Retirement Longitudinal Study 2018 data on middleaged and elderly arthritic individuals,the population was randomly divided into a training set(n=4349)and a validation set(n=1862)at a 7:3 ratio.Based on 10-fold cross-validation,least absolute shrinkage and selection regression was used to screen the model for the best predictor variables.Logistic regression was used to construct the nomogram model.Subject receiver operating characteristic and calibration curves were used to determine model differentiation and accuracy.Decision curve analysis was used to assess the net clinical benefit.RESULTS The prevalence of depressive symptoms in the middle-aged and elderly arthritis population in China was 47.1%,multifactorial logistic regression analyses revealed that gender,age,number of chronic diseases,number of pain sites,nighttime sleep time,education,audiological status,health status,and place of residence were all predictors of depressive symptoms.The area under the curve values for the training and validation sets were 0.740(95%confidence interval:0.726-0.755)and 0.731(95%confidence interval:0.709-0.754),respectively,indicating good model differentiation.The calibration curves demonstrated good prediction accuracy,and the decision curve analysis curves demonstrated good clinical utility.CONCLUSION The risk prediction model developed in this study has strong predictive performance and is useful for screening and assessing depression symptoms in middle-aged and elderly arthritis patients.

Coping review of dementia fear studies among middle-aged and elderly people in the community

This study used Arksey and O’Malley’s scoping review methodology as a framework and searched the following databases:PubMed,Embase,EBSCO,CINAHL,Web of Science,Cochrane Library,Scopus,CNKI,Wanfang,VIP,and the Chinese Biomedical Literature Database.The database is open to December 20,2023,and documents related to the fear of dementia among the elderly in the community are described and analyzed to provide a reference for future research in this field.At the same time,we screened,extracted,and summarized relevant information from 21 included documents(16 in English and 5 in Chinese),which consisted of 16 cross-sectional studies,2 quasi-experimental studies,2 randomized controlled studies,and 1 longitudinal study.Sixteen of the included documents mentioned the incidence or level of dementia fear among the elderly in the community,2 addressed the adverse effects of dementia fear,and 4 reported prevention and intervention measures for dementia fear.In total,there are 8 assessment tools,and the influencing factors are categorized into sociodemographic characteristics,psychological and behavioral characteristics,sociocultural background factors,and health and dementia-related factors.The final conclusion is that the fear of dementia is common among the elderly in the community.In the future,the application of research tools should be expanded among middle-aged individuals,with considerations for other types of dementia in mind.It is recommended to conduct large-scale,multi-center randomized controlled trials while confirming the intervention’s effect on different types of middle-aged and elderly individuals,focusing on the long-term impact of these intervention measures to promote healthy aging.

Sleep quality in middle-aged and elderly hemodialysis patients:Impact of a structured nursing intervention program

BACKGROUND Poor sleep quality is common among hemodialysis patients and can significantly impact their well-being.This study aimed to evaluate the effectiveness of a structured nursing intervention program in improving sleep quality in middleaged and elderly hemodialysis patients.AIM To evaluate the impact of nursing intervention on sleep quality in hemodialysis patients.METHODS This cross-sectional study was conducted in a tertiary hospital,the First Affiliated Hospital of Nanchang University,in 2023.This study included 105 middle-aged and elderly hemodialysis patients aged≥45 years who underwent maintenance hemodialysis for at least 3 mo,utilizing the Pittsburgh Sleep Quality Index(PSQI)to identify poor sleepers.Those identified underwent a 12-wk nursing intervention program focusing on education,relaxation techniques,and counseling.Post-intervention,sleep quality was reassessed using the PSQI.RESULTS The study found that 68.6%of hemodialysis patients were poor sleepers.Following the 12-wk nursing intervention program,there was a significant decrease in the mean global PSQI score from 8.9±3.2 to 5.1±2.7(P<0.001),indicating improved sleep quality.This demonstrated the effectiveness of the structured nursing intervention in enhancing sleep quality for middle-aged and elderly hemodialysis patients.CONCLUSION The structured nursing intervention program focusing on sleep hygiene education,relaxation techniques,and counseling effectively improved sleep quality among middle-aged and elderly hemodialysis patients.The significant decrease in the mean global PSQI score post-intervention indicates the positive impact of tailored nursing interventions in addressing poor sleep quality in this patient population.These findings emphasize the importance of implementing targeted nursing interventions to enhance the quality of life for hemodialysis patients by addressing the prevalent issue of poor sleep quality.

Postoperative delirium:A tragedy for elderly cancer patients

In this editorial,we comment on the article by Hu et al entitled“Predictive modeling for postoperative delirium in elderly patients with abdominal malignancies using synthetic minority oversampling technique”.We wanted to draw attention to the general features of postoperative delirium(POD)as well as the areas where there are uncertainties and contradictions.POD can be defined as acute neurocognitive dysfunction that occurs in the first week after surgery.It is a severe postoperative complication,especially for elderly oncology patients.Although the underlying pathophysiological mechanism is not fully understood,various neuroinflammatory mechanisms and neurotransmitters are thought to be involved.Various assessment scales and diagnostic methods have been proposed for the early diagnosis of POD.As delirium is considered a preventable clinical entity in about half of the cases,various early prediction models developed with the support of machine learning have recently become a hot scientific topic.Unfortunately,a model with high sensitivity and specificity for the prediction of POD has not yet been reported.This situation reveals that all health personnel who provide health care services to elderly patients should approach patients with a high level of awareness in the perioperative period regarding POD.

Metabolic Disorders Increase the Risk to Incident Cardiovascular Disease in Middle-aged and Elderly Chinese

Objective The association of metabolic syndrome （MetS） with cardiovascular diseases （CVD） has not been adequately explored in middle-aged and elderly Chinese. This study aimed to investigate MetS＇ prevalence and its impact on the CVD incidence in this specific population group. Methods A data set of a community-based prospective cohort study was analyzed. A total of 2300 subjects aged 40-94 years were followed up for the CVD events. MetS defined according to the JCDCG criteria was assessed at baseline, and the middle-aged and elderly groups were classified by the WHO definition. Results As compared with the middle-aged group, the prevalence of MetS increased by 0.6 times （34.6% vs. 21.3%） and the incidence density of CVD increased by 4.9 times in the elderly group （52.3/1000 person-year vs. 8.9/1000 person-year）. Furthermore, the multivariate Cox regression revealed that the risk to CVD incidence was independently related to increased waist circumference in the middle-aged group （HR=2.23, P〈0.01） and to elevated blood glucose in the elderly group （HR=1.39, P〈O.01）. Conclusion MetS was highly prevalent in middle-aged and elderly Chinese. MetS significantly increased the risk to OdD incidence in the elderly. All individuals with metabolic disorders should receive active clinical care to reduce the incidence of CVD.

Correlation of Depression with the Functional Profile of Elderly People Living in Homes for the Aged

Introduction: Due to the growth of the elderly population, there is a notable lack of preparation among family members and society to face the challenges of this new reality, resulting in an increasing demand for homes for the aged (HA). It is necessary to understand how the impairment of physical health, mental health and the level of depression can affect the functional capacity of the institutionalized elderly who live in homes for the aged. Objective: To describe the correlation between depression and functionality of elderly people who live in homes for the aged. Method: A cross-sectional, descriptive study with 70 elderly people of both sexes, aged 60 years or older, who live in HA in the state of Rio de Janeiro. Result: It was verified that the female gender was predominant in the HA consulted. The majority of elderly live in HA voluntarily 48.6% and that 41.43% did not complete elementary school. The majority of the elderly 81.43% had the ability to perform basic activities of daily living and the elderly 52.86% had normal psychological pictures. The worsening of the depressive picture is associated with the worse functioning of elderly who live in HA (p < 0.02). Conclusion: Depression is a factor that is associated with the functional capacity of the institutionalized elderly. The worse the functional level of the institutionalized elderly, the greater the chances of presenting a depressive state.

Public Square Dancing Intervention on Subjective Well-Being of Middle-Aged and Elderly People:A Meta-Analysis

Objective:To understand the influence of public square dancing on the subjective well-being of middle-aged and elderly people.Methods:According to the principle of Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines,we search Chinese databases,such as CNKI,Wanfang Data,and VIP,and English databases,such as Proquest,Web of Science,Pubmed,Cochrane,and ScienceDirect,and collect relevant articles at home and abroad from 2006 to December 2019 for meta-analysis in January 2020.Result:A total of 10 articles were included.The meta-analysis results showed that the well-being of middle-aged and elderly people in the public square dancing intervention group was significantly higher than that of the other exercise group and control group(both P<0.01).The results of the subgroup analysis showed the following:Different durations of intervention significantly influence the intervention effect(P<0.01).No difference was found between the effect of the mixed-gender intervention and the individual female intervention(P>0.05).No significant difference was found between the groups with weekly intervention frequency(P>0.05).Conclusion:Public square dancing intervention is effective for middle-aged and elderly people’s subjective well-being.Neither mixed intervention nor the times of weekly intervention have an impact on the intervention effect.However,the length of duration of intervention influences the intervention effect.

Relationship between platelet-lymphocyte ratio and carotid atherosclerosis in middle-aged and elderly patients with type 2 diabetes mellitus

Objective:To investigate the relationship between platelet-lymphocyte ratio(PLR)and carotid atherosclerosis(CAS)in middle-aged and elderly patients with T2DM.Methods:A total of 420 middle-aged and elderly patients with T2DM who were hospitalized in the Endocrinology Department of our hospital from September 2018 to September 2020 and were examined by ultrasound were selected as the subjects.The carotid artery intima-media thickness(CIMT)was examined by color Doppler ultrasonography,including normal CIMT group(n=111),CIMT thickening group(n=103)and CAS plaque group(n=206).The differences of serum PLR levels among the three groups were compared.Multivariate Logistic regression was used to analyze the relationship between PLR and CAS plaque formation.The receiver operating curve(ROC)was used to evaluate the value of multivariate Logistic regression model(Logit P)in the diagnosis of CAS lesions.Results:The mean value of PLR in CAS plaque group(127.86±48.54)was significantly higher than that in CIMT normal group(109.15±48.35).Multivariate Logistic regression analysis showed that after adjusting for other confounding factors,the increase of PLR was an independent risk factor for the occurrence of CAS plaque.ROC showed that the efficacy of multivariate Logit P model in the diagnosis of CAS plaque was(AUC=0.807,95%CI=0.759-0.858).Conclusions:PLR is one of the important risk factors for the occurrence of CAS lesions.At the same time,the multivariate Logistic regression model established in this study has clinical reference value in predicting CAS lesions in middle-aged and elderly patients with T2DM.

Cardiac rehabilitation and exercise therapy in the elderly： Should we invest in the aged？

Coronary heart disease （CHD） is the leading cause of death worldwide and becomes increasingly prevalent among patients aged 65 years and older.Elderly patients are at a higher risk for complications and accelerated physical deconditioning after a cardiovascular event,especially compared to their younger counterparts.The last few decades were privy to multiple studies that demonstrated the beneficial effects of cardiac rehabilitation （CR） and exercise therapy on mortality,exercise capacity,psychological risk factors,inflammation,and obesity among patients with CHD.Unfortunately,a significant portion of the available data in this field pertains to younger patients.A viable explanation is that older patients are grossly underrepresented in these programs for multiple reasons starting with the patient and extending to the physician.In this article,we will review the benefits of CR programs among the elderly,as well as some of the barriers that hinder their participation.

A Study to Examine the Relationship between Social Support and Perception of Being Institutionalized among the Elderly Aged 65 Years and Above Who Are in Institutions in Bulawayo Urban, Zimbabwe

Policies on the elderly in Zimbabwe are based on social networks and social capital in which the care of the elderly rests with the adult children and other relatives including the community. It is argued that social networks and social capital are informal and the weakness in these informal types of social support is that they are difficult to maintain in cases of urbanization, migration and socio-economic hardships. The study sought to examine the relationship between social support and the perception of being institutionalized among the elderly aged 65 years and above who were in institutions in Bulawayo urban. A descriptive quantitative cross-sectional correlational survey method was used. A simple random sampling method was used to recruit respondents. The sample size in this study was 81 respondents. Data was collected using the interview schedule. Analysis was done using the Statistical Package Social for Sciences (SPSS) package, descriptive and inferential statistics. The Pearson’s correlation coefficient showed the relationship between social support and perception of being institutionalized as follows;r = 0.181, p = 0.107. This shows that there is no relationship between social support and perception of being institutionalized among the elderly aged 65 years and above who are in institutions in Bulawayo urban, Zimbabwe.

Feasibility of gastric endoscopic submucosal dissection in elderly patients aged≥80 years

BACKGROUND Endoscopic resection,especially endoscopic submucosal dissection(ESD),is increasingly performed in elderly patients with early gastric cancer,and lesions beyond the expanded indications are also resected endoscopically in some patients.It is essential to assess whether gastric ESD is safe and suitable for elderly patients and investigate what type of lesions carry an increased risk of ESD-related complications.AIM To assess the efficacy and feasibility of gastric ESD for elderly patients,and define high-risk lesions and prognostic indicators.METHODS Among a total of 1169 sessions of gastric ESD performed in Kanagawa Cancer Center Hospital from 2006 to 2014,179 sessions(15.3%)were performed in patients aged≥80 years,and 172 of these sessions were done in patients with a final diagnosis of gastric cancer.These patients were studied retrospectively to evaluate short-term outcomes and survival.The short-term outcomes included the rates of en bloc resection and curative resection,complications,and procedurerelated mortality.Curability was assessed according to the Japanese Gastric Cancer Treatment Guidelines 2010.Fisher’s exact test was used to statistically analyze risk factors.Clinical characteristics of each group were compared using Fisher’s exact test and Mann-Whitney U test.Survival rates at each time point were based on Kaplan-Meier estimation.Overall survival rates were compared between patients with gastric cancer in each group with use of the log-rank test.To identify prognostic factors that jointly predict the hazard of death while controlling for model overfitting,we used the least absolute shrinkage and selection operator(LASSO)Cox regression model including factors curative/noncurative,age,gender,body mass index,prognostic nutritional index,Charlson comorbidity index(CCI),Glasgow prognostic score,neutrophil-to-lymphocyte ratio,and antithrombotic agent use.We selected the LASSO Cox regression model that resulted in minimal prediction error in 10-fold cross-validation.P<0.05 was considered statistically significant.RESULTS The en bloc dissection rate was 97.1%,indicating that a high quality of treatment was achieved even in elderly patients.As for complications,the rates of bleeding,perforation and aspiration pneumonitis were 3.4%,1.1%and 0.6%,respectively.These complication rates indicated that ESD was not associated with a particularly higher risk in elderly patients than in nonelderly patients.A dissection incision>40 mm,lesions associated with depressions,and lesions with ulcers were risk factors for post-ESD bleeding,and location of the lesion in the upper third of the stomach was a risk factor for perforation in elderly patients(P<0.05).Location of the lesion in the lower third of the stomach tended to be associated with a higher risk of bleeding.The overall survival(OS)did not differ significantly between curative and noncurative ESD(P=0.69).In patients without additional surgery,OS rate was significantly lower in patients with a high CCI(≥2)than in those with a low CCI(≤1)(P<0.001).CONCLUSION Gastric ESD is feasible even in patients aged≥80 years.Observation without additional surgery after noncurative ESD is reasonable,especially in elderly patients with CCI≥2.

Clinical outcomes of targeted therapies in elderly patients aged ≥ 80 years with metastatic colorectal cancer

BACKGROUND The 5-fluorouracil-based chemotherapy combined with oxaliplatin or irinotecan is usually used in colorectal cancer(CRC).The addition of a targeted agent(TA) to this combination chemotherapy is currently the standard treatment for metastatic CRC.However,the efficacy and safety of combination chemotherapy for metastatic CRC in patients aged above 80 years has yet to be established.AIM To assess the clinical outcomes and feasibility of combination chemotherapy using a TA in extremely elderly patients with CRC.METHODS Eligibility criteria were:(1) Age above 80 years;(2) Metastatic colorectal cancer;(3) Palliative chemotherapy na?ve;(4) Eastern Cooperative Oncology Group performance status 0-1;and(5) Adequate organ function.Patients received at least one dose of combination chemotherapy with or without TA.Response was evaluated every 8 wk.RESULTS Of 30 patients,the median age of 15 patients treated with TA was 83.0 years and that of those without TA was 81.3 years.The median progression-free survival(PFS) and overall survival(OS) in patients treated with TA were 7.4 mo and 15.4 mo,respectively,compared with 4.4 mo and 15.6 mo,respectively,in patients treated without TA.There was no significant difference in PFS(P:0.193) and OS(P:0.748) between patients treated with and without TA.Common grade 3/4 hematologic toxicities were anemia(16.7%) and neutropenia(10.0%).After disease progression,the median OS of patients who were treated with and without salvage chemotherapy were 23.5 mo and 7.0 mo,respectively,suggesting significant difference in OS(P = 0.001).CONCLUSION Combination chemotherapy with TA for metastatic CRC may be considered feasible in patients aged above 80 years,when with careful caution.Salvage chemotherapy can help improve OS in some selected of these elderly patients.

Sitagliptin for Elderly Patients Aged 75 Years or Older with Inadequately Controlled Type 2 Diabetes with Common Antidiabetes Treatments

Background: The purpose of this study was to evaluate the effects of sitagliptin in elderly patients with type 2 diabetes aged 75 years or older versus those aged 65 - 74 years. Methods: Outpatients aged 65 years or older with type 2 diabetes who received sitagliptin at a dose of 50 mg daily for 6 months were divided into two groups: those who were 75 years and older and those who were 65 - 74 years. The efficacy and safety were retrospectively evaluated by comparison of laboratory values before and after the administration of sitagliptin and by review of adverse events after treatment. Results: One hundred and twelve older patients with type 2 diabetes were studied. Six months after the initiation of sitagliptin, participants’ hemoglobin A1c was significantly decreased by 1.09% ± 0.8% in 65 - 74-year-olds (66 patients;mean age, 69.1 ± 3.0 years;mean HbA1c before administration, 8.4% ± 0.8%) and by 1.05% ± 0.8% in patients 75 years or older (46 patients;mean age, 79.8 ± 4.1 years;mean HbA1c before administration, 8.5% ± 0.7%). There was no significant difference in hemoglobin A1c between the two groups. Furthermore, sitagliptin was well tolerated in both age groups. Conclusions: In elderly patients (75 years or older) with type 2 diabetes, the effect of sitagliptin was similar that in older patients (younger than 75 years) with type 2 diabetes.

Study on Walking Ability after Surgery for Proximal Femoral Fracture in Elderly Patients Aged 75 Years or Older

Background: Fractures of the hip are the cause of hospitalization in the geriatric population. In many cases, hip fractures are a sentinel event signaling a systemic decline in the patient’s health. Methods: A retrospective review of the cases of 88 patients aged 75 years or older with proximal femoral fracture was performed. Fracture types, surgical procedures, walking ability before the injury and at discharge, and waiting time from injury to surgery were obtained. Results: No significant difference was observed in walking ability before injury among patients with femoral neck fracture treated with bipolar hip arthroplasty (BHA) or open reduction and internal fixation (ORIF) and those with trochanteric fracture. The degree of deterioration of walking ability was 0.6 in patients treated with BHA, 1.2 in those with neck fracture treated with ORIF, and 1.1 in those with trochanteric fracture. Deterioration was significantly less severe in patients who received BHA, compared with those who received ORIF. Conclusions: Among the patients aged 75 years or older with femoral neck fracture, those who received BHA had a shorter time interval to the start of walking with parallel assist bars or with walking aids, and also had a higher rate of regaining walking ability.

Elderly Persons Aged 80 Years and Older and Their Nutritional Status

A challenge for health care providers is that there will be a distinct rise globally in the number of elderly people aged 80 years and over. Malnutrition is a well-known problem among elderly people;few studies have focused on the nutritional status of those aged over 80, irrespective of whether they live in nursing homes (NHs) or in ordinary housing. The aim of the study was to examine the nutritional status of elderly people aged 80 or older. The study was cross-sectional with 64 elderly persons (80 - 100 years old) living in NHs (n = 35) or in ordinary housing (n = 29). Their nutritional status was assessed with the Mini Nutritional Assessment. Among the elderly people living in NHs, half were at risk and one fourth were suffering from malnutrition. Ten percent of the elderly persons in ordinary housing were found to be at risk;none were malnourished. Thirty-one percent had BMI values <23. The majority of the participants ate 2 - 3 meals per day and were prescribed more than three medications daily. Although not statistically significant, well-nourished participants were more likely to be married, and to rate their psychological and physical health very good/good compared to participants who were at risk of becoming malnourished or were malnourished. In conclusion, the results indicate that special attention regarding nutritional intake is required for those aged 80 years and older irrespective of type of accommodation. The RNs have a responsibility to identify the problems and needs and to implement and evaluate nutritional care in this age group. There is a further need for knowledge regarding the effects of both nutritional interventions and of their optimum timing.

Research on the mental health condition of the elderly under the institution for the aged

After entering the aging society, the pension problem of the elderly population has become an urgent problem to be solved in the current and future social life of our country. The rapid growth of the elderly population will inevitably bring about changes in the family structures, which leads to the inevitable development trend of the old-age pension institutions for the elderly. With the progress of the society, the needs of the elderly for the old-age pension are not only satisfied with their life care, but also with the spiritual needs. Based on the planning contents of the 13th Five-Year Plan for the elderly, on the basis of the Maslow＇s demand level theory, this paper analyzes the present status of the services of the institutions for the elderly to the elderly psychological health, and concludes that the needs of the emotions of the elderly, the needs of their self-esteem, the needs of their self-realization and their physiological needs of the elderly and their security needs are equally important.

Real-world evidence on the efficacy and safety of vonoprazanamoxicillin dual therapy for Helicobacter pylori treatment in elderly patients

BACKGROUND A dual therapy regimen containing amoxicillin is a common treatment option for the eradication of Helicobacter pylori(H.pylori).While substantial research supports the efficacy and safety of vonoprazan and amoxicillin(VA)dual therapy in the general population,there is still a lack of studies specifically focusing on its safety in elderly patients.AIM To evaluate efficacy and safety of VA dual therapy as first-line or rescue treatment for H.pylori in elderly patients.METHODS As a real-world retrospective study,data were collected from elderly patients aged 60 years and above who accepted VA dual therapy(vonoprazan 20 mg twice daily+amoxicillin 1000 mg thrice daily for 14 days)for H.pylori eradication in the Department of Gastroenterology at Peking University First Hospital between June 2020 and January 2024.H.pylori status was evaluated by^(13)C-urease breath test 6 weeks after treatment.All adverse events(AEs)during treatment were recorded.RESULTS In total,401 cases were screened.Twenty-one cases were excluded due to loss to follow-up,lack of re-examination,or unwillingness to take medication.The total of 380 included cases comprised 250 who received VA dual therapy as first-line treatment and 130 who received VA dual therapy as rescue treatment.H.pylori was successfully eradicated in 239 cases(95.6%)in the first-line treatment group and 116 cases(89.2%)in the rescue treatment group.The overall incidence of AEs was 9.5%for both groups.Specifically,9.2%of patients experienced an AE in the first-line treatment group and 10.0%in the rescue treatment group.Five patients discontinued treatment due to AE,with a discontinuation rate of 1.3%.No serious AE occurred.CONCLUSION The VA dual therapy regimen as a first-line treatment and a rescue therapy was effective and safe for elderly patients aged 60 and older.

Characteristics and demographic factors of traditional Chinese medicine constitution types among elderly individuals in China:A national multistage cluster random study Author links open overlay panel

Objective:To reveal the distribution characteristics and demographic factors of traditional Chinese medicine(TCM)constitution among elderly individuals in China.Methods: Elderly individuals from seven regions in China were selected as samples in this study using a multistage cluster random sampling method.The basic information questionnaire and Constitution in Chinese Medicine Questionnaire(Elderly Edition)were used.Descriptive statistical analysis,chi-squared tests,and binary logistic regression analysis were used.Results: The single balanced constitution(BC)accounted for 23.9%.The results of the major TCM constitution types showed that BC(43.2%)accounted for the largest proportion and unbalanced constitutions ranged from 0.9%to 15.7%.East China region(odds ratio[OR]=2.097;95%confidence interval[CI],1.912 to 2.301),married status(OR=1.341;95%CI,1.235 to 1.457),and managers(OR=1.254;95%CI,1.044 to 1.505)were significantly associated with BC.Age>70 years was associated with qi-deficiency constitution and blood stasis constitution(BSC).Female sex was significantly associated with yang-deficiency constitution(OR=1.646;95%CI,1.52 to 1.782).Southwest region was significantly associated with phlegm-dampness constitution(OR=1.809;95%CI,1.569 to 2.086).North China region was significantly associated with inherited special constitution(OR=2.521;95%CI,1.569 to 4.05).South China region(OR=2.741;95%CI,1.997 to 1.3.763),Central China region(OR=8.889;95%CI,6.676 to 11.835),senior middle school education(OR=2.442;95%CI,1.932 to 3.088),and managers(OR=1.804;95%CI,1.21 to 2.69)were significantly associated with BSC.Conclusions: This study defined the distribution characteristics and demographic factors of TCM constitution in the elderly population.Adjusting and improving unbalanced constitutions,which are correlated with diseases,can help promote healthy aging through the scientific management of these demographic factors.

Analysis of Distribution of Public Toilets within Walking Range around Communities of the Elderly under the Model of Community Home-based Care for the Elderly: A Case Study of Changxindian, Fengtai District, Beijing

In recent years,under the influence of multiple factors such as traditional ideas and living economic conditions,the aging population in China continues to increase.Most of the elderly are more inclined to aged at home,and the first places for elderly activities are communities and the surrounding environment,which greatly affects the convenience of life and happiness of the elderly.In this paper,Changxindian area in Fengtai District of Beijing was as the research object,and detailed calculation and analysis were carried out by using POI data and arcGIS software.The relative location of residential areas and surrounding public toilets was explored,and the best location of public toilets in the daily walking area under the model of community home-based care for the elderly was further studied.

Prevalence rate of osteoporosis in the mid-aged and elderly in selected parts of China

OBJECTIVE: To understand the distribution of prevalence rate of osteoporosis in the middle - aged and elderly in parts of China. METHODS: Bone mineral density (BMD) was measured and questionnaires were taken for 5593 people aged above 40 years in five administrative areas in China selected by the stratified - multi - steps - cluster sampling method. RESULTS: The total prevalence rate of osteoporosis was 16.1%. The prevalence rate among males was 11.5% and among females was 19.9% (P
