Methods: Data were derived from the 2013 wave of the China Longitudinal Healthy Longevity Survey, including a total of 6,179 individuals aged 45 years and above with complete follow-up records. Basic demographic information was collected, and frailty status was assessed using a physical frailty scale. Generalized linear models were employed to analyze the association between the number and combinations of cardiometabolic conditions- such as hypertension, diabetes, heart disease, and stroke-and frailty. Results: The prevalence of cardiometabolic multimorbidity among middle-aged and older adults was 14.23%. After adjusting for sociodemographic covariates, individuals with cardiometabolic multimorbidity had a significantly increased risk of frailty compared to those without such conditions (OR = 1.78, 95% CI: 1.45-2.19), along with higher frailty scale scores (β = 0.26, 95% CI: 0.19-0.34). Compared to individuals without cardiometabolic diseases, those with both hypertension and stroke (OR = 1.18, 95% CI: 1.06-1.31) and those with hypertension, heart disease, and stroke (OR = 1.46, 95% CI: 1.24-1.73) exhibited notably higher frailty risks. Conclusion: There is a significant association between cardiometabolic multimorbidity and frailty in middle- aged and older adults in China, particularly for comorbidity patterns involving hypertension. These findings provide evidence for developing targeted health interventions for aging populations.展开更多

The current study explores the prevalence of depression diagnosis and Geriatric Depression Scale (GDS) symptoms amongst older multimorbid outpatients, and agreement between GDS scores and doctor-diagnosed depression. Method: Deidentified data from the files of 452 patients aged over 64, with chronic conditions present in two or more organ domains, were extracted from the clinical database of a tertiary referral hospital multidisciplinary outpatient clinic in South Australia between 2005 and 2011. Frequency calculations determined the prevalence of depression diagnosis and GDS categories. Logistic regression, cross-tabulation, kappa and ROC graphs explored relationships between variables. Results: A depression diagnosis had been recorded for 71 (15.7%) patients. Using the recommended cut-off scores for the GDS, 225 (49.8%) patients met criteria for mild-severe depressive symptoms, and 96 (21.3%) met criteria for moderate-severe symptoms. Poor agreement was found between doctor diagnosis of depression and a positive screen for depression using a GDS cut-off score of either 5, k = 0.112 (p = 0.001), or 9, k = 0.189 (p < 0.001), although logistic regression found an association between severity of depression and depression diagnosis, OR = 1.15, p < 0.001 (CI = 1.08 - 1.22). Con-clusion: A much higher proportion of patients with multimorbidities reported threshold level depression symptoms than had a recorded diagnosis of depression, suggesting that although likelihood of diagnosis increases with symptom severity, depression often goes undetected in this population. Depressions’ negative impact on prognosis calls for further investigation of the barriers to screening and diagnosis of depression in multimorbid patients.展开更多

The management of patients with several chronic diseases is now the most important challenge facing health care systems in developed countries. Based on the actual medical records of ambulatory care visits, this study investigated the prevalence and patterns of multimorbidity in 55 and older population. Among a cohort comprised of 300,000 beneficiaries selected randomly from the National Health Insurance Research Database of Taiwan in 2001, 42,441 were eligible. These were followed longitudinally 10 years. The prevalence of chronic disease rose from 62.3% to 79.8% and multimorbidity rose from 57.4% to 75.7%. Multimorbidity patterns were found fell in-to four clusters: metabolic diseases, cardiac diseases, mental joints and gastrointestinal tract disorders. Hypertension and diabetes mellitus, as well as hyperplasia of the prostate in men, were the most common chronic diseases. The prevalence of chronic disease increased with age, especially high at age 75 - 79. Thought about the health care system for an ageing society is necessary. Applying the concept of customer experience and strengthening people-centered management in an integrated model of health care, enhancing knowledge and skills in the long-term management of chronic disease, revising clinical guidelines and training professionals in caring for the elderly, reinforcing preventive health services, especially in men’s health, modifying the materials for health education, and planning for health manpower resources will provide a better model to ensure the health care for people with multimorbidity.展开更多

Multimorbidity is defined as the presence of two or more chronic conditions in the same person, leading to a high risk of care dependency. The aim of this review was to illuminate the challenges faced by the healthcare services in managing the needs of older patients with multimorbidity. A systematic review was performed, a total of 1,965 abstracts were read and nine quantitative studies included. Data were analysed by thematic synthesis, revealing six themes: A frequent problem in older female patients;High healthcare expenditure and costs, Medication management problems, Social inequities, Complex healthcare and consultation needs and High mortality. The study highlights that healthcare professionals struggle to obtain suitable guidelines for the care of patients with multimorbidity while trying to respond to their needs. Patient-centred integration across settings and coordination in clinical practice are necessary. The healthcare system today does not seem to focus on patient safety and preventing harm. Older patients should be reviewed by a healthcare professional responsible for coordinating their care. To ensure safe and effective care for elderly persons with multimorbidity, the healthcare services should abandon the current focus on managing innumerable individual diseases and conditions.展开更多

文摘The rising prevalence of chronic multimorbidity poses substantial challenges to healthcare systems,necessitating the development of innovative management strategies to optimize patient care and system efficiency.The study by Fontalba-Navas et al investigates the implementation of a novel high complexity unit(HCU)specifically designed to improve the management of patients with chronic complex conditions.By adopting a multidisciplinary approach,the HCU aims to provide comprehensive,patient-centered care that enhances health outcomes and alleviates the strain on traditional hospital services.Utilizing a longitudinal analysis of data from the Basic Minimum Data Set,this study compares hospitalization metrics among the HCU,Internal Medicine,and other departments within a regional hospital throughout 2022.The findings reveal that the HCU's integrated care model significantly reduces readmission rates and boosts patient satisfaction compared to conventional care practices.The study highlights the HCU's potential as a replicable model for managing chronic multimorbidity,emphasizing its effectiveness in minimizing unnecessary hospitalizations and enhancing the overall quality of patient care.This innovative approach not only addresses the complexities associated with chronic multimorbid conditions but also offers a sustainable framework for healthcare systems confronting similar challenges.
文摘Objective: To explore the association between cardiometabolic multimorbidity and frailty among middle- aged and older adults in China. Methods: Data were derived from the 2013 wave of the China Longitudinal Healthy Longevity Survey, including a total of 6,179 individuals aged 45 years and above with complete follow-up records. Basic demographic information was collected, and frailty status was assessed using a physical frailty scale. Generalized linear models were employed to analyze the association between the number and combinations of cardiometabolic conditions- such as hypertension, diabetes, heart disease, and stroke-and frailty. Results: The prevalence of cardiometabolic multimorbidity among middle-aged and older adults was 14.23%. After adjusting for sociodemographic covariates, individuals with cardiometabolic multimorbidity had a significantly increased risk of frailty compared to those without such conditions (OR = 1.78, 95% CI: 1.45-2.19), along with higher frailty scale scores (β = 0.26, 95% CI: 0.19-0.34). Compared to individuals without cardiometabolic diseases, those with both hypertension and stroke (OR = 1.18, 95% CI: 1.06-1.31) and those with hypertension, heart disease, and stroke (OR = 1.46, 95% CI: 1.24-1.73) exhibited notably higher frailty risks. Conclusion: There is a significant association between cardiometabolic multimorbidity and frailty in middle- aged and older adults in China, particularly for comorbidity patterns involving hypertension. These findings provide evidence for developing targeted health interventions for aging populations.

文摘Background There are several surrogate indicators of abdominal fat deposition,including tri-ponderal mass index(TMI),lipid accumulation product(LAP),and the Chinese visceral adiposity index(CVAI).In spite of this,it remains unclear whether these indices have a longitudinal relationship with the prevalence of cardiometabolic multimorbidity(CM),a pressing global health issue.This research investigated the association between CVAI and CM compared to other indicators of visceral obesity.Methods 6638 participants(aged>45)from the China Health and Retirement Longitudinal Study(CHARLS)were analyzed for incident CM.Cox proportional models were adopted to explore whether the level of CVAI was correlated with the risk of CM.Harrell's concordance statistic(C-statistic)was applied to compare predictive values.Sensitivity and subgroup analyses were implemented for the steadiness of the results.Results Over 4 years,266(4.01%)participants developed CM.A 1-standard deviation(SD)increase in the levels of CVAI,body mass index(BMI),LAP,and TMI was associated with greater CM risk after adjusting for confounders[hazard ratios(HRs):2.20,95%confidence interval(CI):1.88-2.57,1.92(95%CI:1.55-2.38),1.20(95%CI:1.12-1.27),and 1.50(95%CI:1.35-1.66),respectively].CVAI outperformed other indices in predictive performance.Subgroup analysis revealed younger participants or those living alone were more prone to developing CM.Results were potent after finishing all sensitivity analyses.Conclusions The study highlighted a positive correlation between the level of CVAI and CM risk.CVAI's superior predictive performance positions it as a reliable indicator for identifying individuals at heightened CM risk.

文摘Background:The prevalence of multimorbidity is increasing,with a notable shift towards younger age groups.Methods:Convenience sampling was employed to select 15,988 young and middle-aged adults in Chongqing as the study population.The Apriori algorithm was used to identify the multimorbidity patterns within this population,while an unordered binary logistic regression model was applied to assess the association between sleep,diet and the risk of multimorbidity.Results:The study population had an average age of 39.2±10.1 years.Apriori association rules revealed that the most prevalent binary chronic disease multimorbidity pattern was dyslipidaemia+hypertension(14.78%),while the most common ternary chronic disease multimorbidity pattern was diabetes+dyslipidaemia+hypertension(9.66%).The logistic regression analysis revealed that a lower rating of sleep quality was associated with an elevated risk of multimorbidity(odds ratio(OR)=1.17,95%confidence interval(CI):1.01,1.36).Individuals who adhere to a meat-based diet(OR=1.45,95%CI:1.25,1.68)and those with elevated salt intake(OR=1.22,95%CI:1.01,1.47)were also observed to have an increased risk of multimorbidity.Additionally,a greater likelihood of multimorbidity was observed among those following a spicy diet(OR=1.3,95%CI:1.11,1.52)and consuming more oil(OR=1.16,95%CI:1.01,1.33).Conclusion:A poor sleep quality and a dietary preference for meat-based,salt,spicy and oils were found to be associated with an increased risk of multimorbidity progression among young and middle-aged populations.It is recommended that young and middle-aged adults should pay attention not only to sleep duration but also to sleep quality and improve dietary habits to reduce the likelihood of multimorbidity.
文摘Objective:To review the research status and progress of minimally disruptive medicine(MDM)with a view and to provide a theoretical basis for reducing the treatment burden of patients with multimorbidity.Methods:"Minimal Destructive Medicine"was used as searching term in HowNet Database and Wanfang Database,and"Minimally Disruptive Medicine"was used as searching term in PubMed database.The literature was reviewed for a review of the concepts of minimally destructive medicine(MDM),four basic principles,care models,and tools and strategies for clinical implementation.Results:MDM was developed for the coexistence burden of chronic diseases.It had formed a detailed and detailed application of basic principles and care models.The tools and strategies developed by MDM have been applied in clinical practice with good Results.Conclusion:MDM has a positive effect on reducing the burden of treatment for the multimorbidity and it is worthy of further research and promotion.

文摘Objective To investigate the impact of multimorbidity on China’s healthcare utilization and expenditure.Methods A two-part model was used to analyze the outpatient cares based on the data from CHARLS 2015 wave.Results and Conclusion As the prevalence of multimorbidity was 36.6%among 15523 middle-aged and elderly respondents in China,the multimorbidity increased the likelihood of outpatient service,while the total outpatient expenditure did not increase significantly as well as the OOP expenditure.Secondly,although there was a similar probability of outpatient visit,the patients with multimorbidity excluding diabetes and(or)hypertension,had not been concerned by China’s Chronic Condition Management Programs(CCCMP)yet.Thirdly,the patients with multimorbidity increased the outpatient visits to different types of hospitals.Under CCCMP intervention,the patients did not switch from the county/city hospital to primary healthcare centers and township hospital.A costeffective strategy for providing services to patients with multimorbid conditions is needed,the focus of CCCMP should be switched from the single chronic disease to the multimorbidity.
文摘Background:Multimorbidity of intestinal cancer(IC),type 2 diabetes(T2D)and obesity is a complex set of diseases,affected by environmental and genetic risk factors.High-fat diet(HFD)and oral bacterial infection play important roles in the etiology of these diseases through inflammation and various biological mechanisms.Methods:To study the complexity of this multimorbidity,we used the collaborative cross(CC)mouse genetics reference population.We aimed to study the multimorbidity of IC,T2D,and obesity using CC lines,measuring their responses to HFD and oral bacterial infection.The study used 63 mice of both sexes generated from two CC lines(IL557 and IL711).For 12 weeks,experimental mice were maintained on specific dietary regimes combined with co-infection with oral bacteria Porphyromonas gingivalis and Fusobacterium nucleatum,while control groups were not infected.Body weight(BW)and results of a intraperitoneal glucose tolerance test(IPGTT)were recorded at the end of 12 weeks,after which length and size of the intestines were assessed for polyp counts.Results:Polyp counts ranged between 2 and 10 per CC line.The combination of HFD and infection significantly reduced(P<.01)the colon polyp size of IL557 females to 2.5 cm 2,compared to the other groups.Comparing BW gain,IL557 males on HFD gained 18 g,while the females gained 10 g under the same conditions and showed the highest area under curve(AUC)values of 40000-45000(min mg/dL)in the IPGTT.Conclusion:The results show that mice from different genetic backgrounds respond differently to a high fat diet and oral infection in terms of polyp development and glucose tolerance,and this effect is gender related.
文摘The aim of the present study was to measure the prevalence of multimorbidity in Bangladesh,India and China,and to assess the relationship between multimorbidity and patient's opinion regarding their involvement in healthcare decision-making and overall satisfaction of healthcare system.Cross-sectional data on 18696 men and women aged 18 and above were collected from the World Health Survey of World Health Organization(WHO).Outcome variables were subjective rating of(1)healthcare system's ability to involve patients in decision-making,and(2)satisfaction with the way healthcare system runs in the country.Self-reported chronic conditions were used to measure the prevalence of multimorbidity.Out of 9 chronic conditions,back pain,arthritis,and chronic cough appeared to be the most prevalent ones among majority of the participants.About one-third of the participants in China(30.7%)and two-thirds in Bangladesh(66.1%)and India(66.6%)reported having at least one chronic illness.Prevalence of multimorbidity was highest in India(34.3%)followed by Bangladesh(28.8%)and China(14.3%).In Bangladesh,India and China,respectively 70.5%,41.7%,61.3%women and 54.5%,42.8%and 58.8%men expressed dissatisfaction regarding the way healthcare system runs in their country.In Bangladesh and India,men who were living with multimorbidity were more likely to rate the patient-centeredness as"bad"than those who had no disease illness.This study suggests that the prevalence of multimorbidity was remarkably high especially in Bangladesh and India.Higher likelihood of dissatisfaction about healthcare system among multimorbid patients might be indicative of inadequacy in the provision of care in qualitative and quantitative terms.
文摘Objectives: Depression may be under-diagnosed and under-treated amongst older adults with multiple chronic illnesses. The current study explores the prevalence of depression diagnosis and Geriatric Depression Scale (GDS) symptoms amongst older multimorbid outpatients, and agreement between GDS scores and doctor-diagnosed depression. Method: Deidentified data from the files of 452 patients aged over 64, with chronic conditions present in two or more organ domains, were extracted from the clinical database of a tertiary referral hospital multidisciplinary outpatient clinic in South Australia between 2005 and 2011. Frequency calculations determined the prevalence of depression diagnosis and GDS categories. Logistic regression, cross-tabulation, kappa and ROC graphs explored relationships between variables. Results: A depression diagnosis had been recorded for 71 (15.7%) patients. Using the recommended cut-off scores for the GDS, 225 (49.8%) patients met criteria for mild-severe depressive symptoms, and 96 (21.3%) met criteria for moderate-severe symptoms. Poor agreement was found between doctor diagnosis of depression and a positive screen for depression using a GDS cut-off score of either 5, k = 0.112 (p = 0.001), or 9, k = 0.189 (p < 0.001), although logistic regression found an association between severity of depression and depression diagnosis, OR = 1.15, p < 0.001 (CI = 1.08 - 1.22). Con-clusion: A much higher proportion of patients with multimorbidities reported threshold level depression symptoms than had a recorded diagnosis of depression, suggesting that although likelihood of diagnosis increases with symptom severity, depression often goes undetected in this population. Depressions’ negative impact on prognosis calls for further investigation of the barriers to screening and diagnosis of depression in multimorbid patients.
文摘Patients with multimorbidity are becoming the norm rather than the exception. The management of patients with several chronic diseases is now the most important challenge facing health care systems in developed countries. Based on the actual medical records of ambulatory care visits, this study investigated the prevalence and patterns of multimorbidity in 55 and older population. Among a cohort comprised of 300,000 beneficiaries selected randomly from the National Health Insurance Research Database of Taiwan in 2001, 42,441 were eligible. These were followed longitudinally 10 years. The prevalence of chronic disease rose from 62.3% to 79.8% and multimorbidity rose from 57.4% to 75.7%. Multimorbidity patterns were found fell in-to four clusters: metabolic diseases, cardiac diseases, mental joints and gastrointestinal tract disorders. Hypertension and diabetes mellitus, as well as hyperplasia of the prostate in men, were the most common chronic diseases. The prevalence of chronic disease increased with age, especially high at age 75 - 79. Thought about the health care system for an ageing society is necessary. Applying the concept of customer experience and strengthening people-centered management in an integrated model of health care, enhancing knowledge and skills in the long-term management of chronic disease, revising clinical guidelines and training professionals in caring for the elderly, reinforcing preventive health services, especially in men’s health, modifying the materials for health education, and planning for health manpower resources will provide a better model to ensure the health care for people with multimorbidity.
文摘Research fails to provide an overview of the challenges involved in caring for older patients with multimorbidity. Multimorbidity is defined as the presence of two or more chronic conditions in the same person, leading to a high risk of care dependency. The aim of this review was to illuminate the challenges faced by the healthcare services in managing the needs of older patients with multimorbidity. A systematic review was performed, a total of 1,965 abstracts were read and nine quantitative studies included. Data were analysed by thematic synthesis, revealing six themes: A frequent problem in older female patients;High healthcare expenditure and costs, Medication management problems, Social inequities, Complex healthcare and consultation needs and High mortality. The study highlights that healthcare professionals struggle to obtain suitable guidelines for the care of patients with multimorbidity while trying to respond to their needs. Patient-centred integration across settings and coordination in clinical practice are necessary. The healthcare system today does not seem to focus on patient safety and preventing harm. Older patients should be reviewed by a healthcare professional responsible for coordinating their care. To ensure safe and effective care for elderly persons with multimorbidity, the healthcare services should abandon the current focus on managing innumerable individual diseases and conditions.

文摘Introduction:Chronic diseases and multimorbidity are increasingly prevalent among older adults in China,contributing substantially to hospitalization burden.However,real-world evidence on their direct medical expenditures remains limited.Methods:This study employed a retrospective analysis by using hospital discharge data from Guangzhou during 2017–2019,and adopted generalized linear models(GLMs)to estimate hospitalization expenditures across chronic disease and multimorbidity patterns.Results:Older patients with multimorbidity incurred nearly double the median annual hospitalization expenditures(3,708 USD vs.1,844 USD)and 45%higher costs per additional condition compared to single diseases.Hospitalization cost varied by specific diseases and multimorbidity patterns.Schizophrenia(7,421.3 USD)has the highest annual total hospitalization expenditure(THE)among single chronic diseases while the combination of cancer+CVD+heart disease(10,698.8 USD for THE,4,024.6 USD for out-of-pocket expenditure)ranked the top expenditures among multimorbidity patterns.Approximately 57.1%of disease combinations exhibited super-additive spending.Conclusion:This study provides robust evidence of the substantial economic burden of chronic diseases and multimorbidity.The findings underscore the need for an integrated care model,evidence-based strategies to optimize healthcare resource allocation and health outcomes in aging populations.

文摘Coronary heart disease and ischemic stroke are common cardiovascular and cerebrovascular diseases with a high multimorbidity rate.According to the theory of traditional Chinese medicine(TCM),the phlegm and blood stasis obstructing the LuòMàis pattern is the pathological basis,and the formation of phlegm and blood stasis is the key pathological factor for cardiocerebral vascular multimorbidity,implying that the treatment of cardiocerebral vascular multimorbidity should focus on eliminating phlegm and blood stasis simultaneously.Based on the discovery of modern medicine that cardiocerebral vascular multimorbidity is mostly related to lipid deposition,inflammation,atherosclerosis,microcirculation disorders,and hemodynamics,it is believed that the core pathological features of cardiocerebral vascular multimorbidity include atherosclerosis and microcirculation disorders,coinciding with the pathological mechanism that phlegm and blood stasis are formed and then obstruct the Luò Màis in the heart and brain in TCM.This paper combined modern medicine and TCM theories,analyzed the pathogenesis of coronary heart disease and ischemic stroke from the perspective of phlegm and blood stasis obstructing the Luò Màis pattern,and discussed the multimorbidity mechanism so as to provide theoretical basis for clinical treatment.

文摘Yu et al's study has advanced the understanding of the neural mechanisms underlying major depressive disorder(MDD)in adolescents,emphasizing the significant role of the amygdala.While traditional diagnostic methods have limitations in objectivity and accuracy,this research demonstrates a notable advancement through the integration of machine learning techniques with neuroimaging data.Utilizing resting-state functional magnetic resonance imaging(fMRI),the study investigated functional connectivity(FC)in adolescents with MDD,identifying notable reductions in regions such as the left inferior temporal gyrus and right lingual gyrus,alongside increased connectivity in Vermis-10.The application of support vector machines(SVM)to resting-state fMRI(rs-fMRI)data achieved an accuracy of 83.91%,sensitivity of 79.55%,and specificity of 88.37%,with an area under the curve of 0.6765.These results demonstrate how SVM analysis of rs-fMRI data represents a significant improvement in diagnostic precision,with reduced FC in the right lingual gyrus emerging as a particularly critical marker.These findings underscore the critical role of the amygdala in MDD pathophysiology and highlight the potential of rs-fMRI and SVM as tools for identifying reliable neuroimaging biomarkers.

文摘Background:Few studies have assessed the relationship between multimorbidity patterns and mortality risk in the Chinese population.We aimed to identify multimorbidity patterns and examined the associations of multimorbidity patterns and the number of chronic diseases with the risk of mortality among Chinese middle-aged and older adults.Methods:We used data from the China Kadoorie Biobank and included 512,723 participants aged 30 to 79 years.Multimorbidity was defined as the presence of two or more of the 15 chronic diseases collected by self-report or physical examination at baseline.Multimorbidity patterns were identified using hierarchical cluster analysis.Cox regression was used to estimate the associations of multimorbidity patterns and the number of chronic diseases with all-cause and cause-specific mortality.Results:Overall,15.8%of participants had multimorbidity.The prevalence of multimorbidity increased with age and was higher in urban than rural participants.Four multimorbidity patterns were identified,including cardiometabolic multimorbidity(diabetes,coronary heart disease,stroke,and hypertension),respiratory multimorbidity(tuberculosis,asthma,and chronic obstructive pulmonary disease),gastrointestinal and hepatorenal multimorbidity(gallstone disease,chronic kidney disease,cirrhosis,peptic ulcer,and cancer),and mental and arthritis multimorbidity(neurasthenia,psychiatric disorder,and rheumatoid arthritis).During a median of 10.8 years of follow-up,49,371 deaths occurred.Compared with participants without multimorbidity,cardiometabolic multimorbidity(hazard ratios[HR]=2.20,95%confidence intervals[CI]:2.14-2.26)and respiratory multimorbidity(HR=2.13,95%CI:1.97-2.31)demonstrated relatively higher risks of mortality,followed by gastrointestinal and hepatorenal multimorbidity(HR=1.33,95%CI:1.22-1.46).The mortality risk increased by 36%(HR=1.36,95%CI:1.35-1.37)with every additional disease.Conclusion:Cardiometabolic multimorbidity and respiratory multimorbidity posed the highest threat on mortality risk and deserved particular attention in Chinese adults.

文摘Objective:To characterize complex multimorbidity among cancer survivors and evaluate the association between cancer survivorship,time since cancer diagnosis,and self-reported fair/poor health,self-rated worse health in 2 years,and 2-year mortality.Methods:We used the 2010-2012 Health and Retirement Study.Cancer survivors were indi-viduals who reported a(nonskin)cancer diagnosis 2 years or more before the interview.We defined complex multimorbidity as the co-occurrence of chronic conditions,functional limitations,and/or geriatric syndromes.In addition to descriptive analyses,we used logistic regression to evaluate the independent association between cancer survivor status and health outcomes.We also examined whether cancer survivorship differed by the number of years since diagnosis.Results:Among 15,808 older adults(age≥50 years),11.8%were cancer survivors.Compared with cancer-free individuals,a greater percentage of cancer survivors had complex multimorbidity:co-occurring chronic conditions,functional limitations,and geriatric syndromes.Cancer survivor-ship was significantly associated with self-reported fair/poor health,self-rated worse health in 2 years,and 2-year mortality.These effects declined with the number of years since diagnosis for fair/poor health and mortality but not for self-rated worse health.Conclusion:Cancer survivor status is independently associated with more complex multi-morbidity,and with worse health outcomes.These effects attenuate with time,except for patient perception of being in worse health.

文摘Given the rapid increase in the prevalence of chronic diseases in aging populations,this prospective study including 17707 adults aged≥45 years from China Health and Retirement Longitudinal Study was used to estimate the associations between chronic discase,multimorbidity,and depression among middle-aged and elderly adults in China,and explore the mediating factors.Depressive symptoms were assessed using the 10-item Centre for Epidemiological Studies Depression Scale(CES-D-10)questionnaire.Twelve chronic physical conditions,including hypertension,diabetes,dyslipidemia,cancer,chronic lung disease,liver disease,heart failure,stroke,kidney disease,arthritis or rheumatism,asthma,digestive disease were assessed.The prevalence rates for physical multimorbidity and depression(CES-D-10≥10)were 43.23%and 36.62%,respectively.Through multivariable logistic models and generalized estimating equation(GEE)models,we found all 12 chronic physical conditions,and multimorbidity were significantly associated with depression.Both mobility problems and chronic pain explained more than 30%of the association for all chronic conditions,with particularly high percentages for stroke(51.56%)and cancer(51.06%)in mobility problems and cancer(53.35%)in chronic pain.Limited activities of daily living(ADL)explained 34.60%of the stroke-cancer relationship,while sleep problems explained between 10.15%(stroke)and 14.89%(chronic lung disease)of the association.Individuals with chronic diseases or multimorbidity are significantly more likely to be depressed.Functional symptoms involving limitations of ADL and mobility difficulties mediated much of the association between chronic diseases and incident depression.These symptoms could be targeted for interventions to ameliorate the incidence of depression among individuals with chronic conditions.
文摘Objectives:To describe the characteristics and relationships of social isolation and health promoting behaviors of Chinese older adults with different health statuses.Methods:Totally 485 older adults were recruited.They were divided into three groups based on their health status:healthy group(n=72),group with one disease(n=183)and group with multimorbidity(n=230).Lubben Social Network Scale-6 and Health-Promoting Lifestyle Profile II were used to measure their social isolation and health-promoting behaviors,respectively.Results:Among the aged with one disease or multimorbidity,30.6%(56/183)and 31.7%(73/230)were socially isolated,respectively,based on the score of the Lubben Social Network Scale-6.The three groups differed significantly in health-promoting behaviors and scores on several subscales.The group with multimorbidity exhibited more social isolation and fewer health-promoting behaviors than other groups.Social isolation was among the factors adversely affecting health-promoting behaviors in older adults.Conclusions:Health care providers should help older adults with multimorbidity preserve the remaining abilities to improve health-promoting behaviors.Meanwhile,it is important to support healthy older adults to increase self-responsibility to achieve healthy aging.
