The Role of Place Attachment in the Relationship between Attitudes toward Aging and Subjective Well-Being among Community-Dwelling Older Adults in Taiwan.

Subjective well-being presents a societal challenge for vulnerable older adults. This study aims to investigate the mediating role of place attachment in the relationship between attitudes toward aging and subjective well-being among community-dwelling older adults in Taiwan. Two waves of investigations were conducted to examine the interplay between attitudes toward aging, subjective well-being, and place attachment among older adults. In Wave I, 1190 participants were enrolled, revealing predominantly younger cohorts with substantial educational levels. The subsequent Wave II involved 483 participants, maintaining continuity in characteristics. Subjective well-being remained moderate across waves, with prevalent positive attitudes toward aging. Place attachment scores indicated moderate to high associations. After controlling for demographics, structural equation modeling (SEM) in both waves revealed significant positive associations: attitudes toward aging influenced well-being, attitudes toward aging were positively associated with place attachment, and place attachment was positively related to well-being. Mediation testing confirmed the mediating role of place attachment in the relationship between attitudes toward aging and well-being. These findings underscore the important role of place attachment. It is evident that improving attitudes toward aging is an effective intervention which can lead to a better sense of well-being by enhancing place attachment to empower civil society.

Clinimetric Properties of the "FIND-NEEDS" to Screen Geriatric Conditions.

INTRODUCTION: Comprehensive geriatric assessment (CGA) is used to thoroughly assess and identify complex healthcare problems among older adults. However, administration of CGA is time-consuming and labor intensive. A simple screening tool with the mnemonic "FIND-NEEDS" was developed to quickly identify common geriatric conditions. The present study was to evaluate the clinimetric properties of the FIND-NEEDS. METHODS: The participants comprised first-visiting older adults aged 65 years and above (and who were able to communicate by themselves or with the help of a caregiver) who were assessed (October to December, 2021) using the FIND-NEEDS and CGA at geriatric outpatient clinics of a tertiary, referred medical center. The FIND-NEEDS was examined for its criterion-related validity and compared with the CGA results. Two types of scoring (summed score and binary score) of FIND-NEEDS and CGA were analyzed using Spearman correlation, sensitivity and specificity, and area under receiver operating characteristic curve (AUC). RESULTS: The mean age of the 114 outpatients was 78.3 ± 7.6 years, and 79 (69.3%) were female. The internal consistency was excellent when using all FIND-NEEDS items, and was acceptable when using domain scores. Exploratory factor analysis showed that most of the FIND-NEEDS domain scores had factor loadings higher than 0.3. Intercorrelations of binary scores between domains of FIND-NEEDS and CGA showed most domains were moderately correlated. The overall correlation of summed scores between FIND-NEEDS and CGA was high. The FIND-NEEDS summed score was moderately correlated with CGA score (r = 0.494; p < 0.001), and the binary score showed excellent correlation (r = 0.944; p < 0.001). When using the CGA score as the gold standard, the FIND-NEEDS showed excellent AUC (0.950), sensitivity (1.00), and specificity (0.90). DISCUSSION/CONCLUSION: The present study demonstrated that the FIND-NEEDS had acceptable clinimetric properties to screen for geriatric problems among older adults. Further in-depth assessment and care plan can then be conducted afterwards.

Estimation of disability free life expectancy in non small cell lung cancer based on real world data.

To quantify the societal impact of disability in patients with non-small cell lung cancer (NSCLC), this study estimated the disability-free life expectancy (DFLE), loss-of-DFLE and explored their associations with quality-adjusted life expectancy (QALE) and loss-of-QALE. We interlinked national databases and applied a rolling-over algorithm to estimate the lifetime survival function for patients with NSCLC. Using the EuroQOL-5 Dimension (EQ-5D) and Barthel index (BI), we repeatedly measured the quality-of-life and disability functions of NSCLC patients who visited our hospital from 2011 to 2020. Age-, sex-matched referents were simulated from lifetables of the same calendar year of diagnosis. We categorized BI scores ≤ 70 as in need of long-term care and constructed linear mixed models to estimate the utility values and disability scores. We collected 960 cases and 3088 measurements. The proportions of measurements without disability at age 50-64 and in stage I-IIIa, 50-64 and stage IIIb-IV, 65-89 and stage I-IIIa and 65-89 and stage IIIb-IV were 97.3%, 89.3%, 94.8%,78.3%, corresponding to DFLEs of 15.3, 2.4, 6.8, 1.2 years and losses-of-DFLE of 8.1, 20.7, 4.0, 8.6 years, respectively, indicating that advanced stage had a stronger effect than old age. Survivors in advanced stages showed increased demands for assistance in almost all subitems. The DFLEs seemed to be approximate to the QALEs and the latter were shorter than the former due to discomfort and depression. From a societal perspective, future health technology assessment should consider the impact of lifetime duration of functional disability. Early diagnosis of NSCLC may decrease the burden of long-term care.

Moonlighting glyceraldehyde-3-phosphate dehydrogenase (GAPDH) protein of Lactobacillus gasseri attenuates allergic asthma via immunometabolic change in macrophages.

BACKGROUND: The extra-intestinal effects of probiotics for preventing allergic diseases are well known. However, the probiotic components that interact with host target molecules and have a beneficial effect on allergic asthma remain unknown. Lactobacillus gasseri attenuates allergic airway inflammation through the activation of peroxisome proliferator- activated receptor γ (PPARγ) in dendritic cells. Therefore, we aimed to isolate and investigate the immunomodulatory effect of the PPARγ activation component from L. gasseri. METHODS: Culture supernatants of L. gasseri were fractionated and screened for the active component for allergic asthma. The isolated component was subjected to in vitro functional assays and then cloned. The crystal structure of this component protein was determined using X-ray crystallography. Intrarectal inoculation of the active component-overexpressing Clear coli (lipopolysaccharide-free Escherichia coli) and intraperitoneal injection of recombinant component protein were used in a house dust mite (HDM)-induced allergic asthma mouse model to investigate the protective effect. Recombinant mutant component proteins were assayed, and their structures were superimposed to identify the detailed mechanism of alleviating allergic inflammation. RESULTS: A moonlighting protein, glycolytic glyceraldehyde 3-phosphate dehydrogenase (GAPDH), LGp40, that has multifunctional effects was purified from cultured L. gasseri, and the crystal structure was determined. Both intrarectal inoculation of LGp40-overexpressing Clear coli and intraperitoneal administration of recombinant LGp40 protein attenuated allergic inflammation in a mouse model of allergic asthma. However, CDp40, GAPDH isolated from Clostridium difficile did not possess this anti-asthma effect. LGp40 redirected allergic M2 macrophages toward the M1 phenotype and impeded M2-prompted Th2 cell activation through glycolytic activity that induced immunometabolic changes. Recombinant mutant LGp40, without enzyme activity, showed no protective effect against HDM-induced airway inflammation. CONCLUSIONS: We found a novel mechanism of moonlighting LGp40 in the reversal of M2-prompted Th2 cell activation through glycolytic activity, which has an important immunoregulatory role in preventing allergic asthma. Our results provide a new strategy for probiotics application in alleviating allergic asthma.

Multidimensional Determinants of Well-Being Among Community-Dwelling Older Adults During the Early Stage of the COVID-19 Pandemic in Taiwan.

Objectives: Due to the insufficient and inadequate policies on the psychological well-being of the aged population, we aimed to examine the multidimensional determinants of well-being during the early stage of the COVID-19 pandemic. Method: Data were collected from face-to-face interviews with1,232 participants aged 50 and older living in Southern Taiwan. We used multivariate logistic regression to examine the associations between demographics, the physical health, mental health, social ties domains, and well-being. Results: We found that (i) in physical health, no dental problems and exercise were related to better well-being; (ii) in mental health, stress and depression decreased well-being, but laughing every day, and a positive attitude toward aging had adverse effects; and (iii) in social ties, subjective social status, family support, and place attachment to the community were positively associated with well-being. Discussion: Our findings highlight the multidimensional needs at the individual and community levels for the Chinese population.

[Community Innovation and Regional Sustainability: A Case Study on an Elder Social Survey Conducted by National Cheng Kung University].

National Cheng Kung University (NCKU) promotes university social responsibility and strives to ensure that all of its teaching staff and students engage in academics in a manner that incorporates both social awareness and social practice. The NCKU team has launched a series of social practice and research projects focused on accompanying and caring for older adults who live in the community, looking to establish a social practice model that bridges university teaching and research to practical community needs. The objective of this initiative is to develop an innovative model of social support and a new model for younger generations to work with older adults living in the community. The results of this survey project show better well-being in older adults to be associated with the following sets of traits: exercising regularly and lacking dental problems; engaging in daily laughter and holding positive aging perceptions; and having a higher subjective social status, more family support, and a sense of community attachment. The study results imply that multiple factors affect well-being in the context of caring for community-dwelling older adults and social development, especially during the current COVID-19 pandemic.

Approaching person-centered long-term care: The trajectories of intrinsic capacity and functional decline in Taiwan.

AIM: To examine the longitudinal trajectory of intrinsic capacity over a 3-year period among long-term care recipients in Taiwan, its association with functional decline and the onset of severe dependency. METHODS: A total of 9448 individuals aged ≥50 years utilizing home and community-based long-term care services with complete data from three separate evaluations in Taiwan were included in the study. We carried out a latent class linear mixed model to identify heterogeneous patterns of intrinsic capacity over time, a mixed-effects model to investigate their impact on activities of daily living and a Kaplan-Meier analysis to examine the onset year of severe dependency among different intrinsic capacity classes. RESULTS: The results identified four classes sharing similar longitudinal the intrinsic capacity trajectories: "high-stable" (20.13%), "normal-stable" (40.58%), "sensory-dysfunction" (29.53%) and "all-dysfunction" (9.76%). Individuals with predisposing characteristics were associated with lower activities of daily living, with the exception of age and education level. In addition, the poor intrinsic capacity class (b from -16.94 to -6.61, P < 0.001) had a worse evolution in terms of activity of daily living scores, and was associated with an earlier onset of severe dependency in 2.5 years in the all-dysfunction class. CONCLUSIONS: Heterogeneous patterns of intrinsic capacity that delay further functional decline are promising markers of function trajectories for a person-centered care approach in long-term care services. Targeting the needs of intrinsic capacity groups to prevent functional decline offer insights into: (i) strengthening function-centered care modalities to delay severe dependency as individuals get older; and (ii) validating regular monitoring intrinsic capacity as an early warning system to achieve healthy aging.

The Effects of in-Home Respite Care on the Burden of Caregivers in Taiwan.

The utilization rate of respite care in Taiwan is low, and past studies that evaluated the effects of in-home respite care on caregiver burden are few. This two-wave panel study used Taiwan's long-term care plan 1.0 database and included 2342 care recipient-caregiver dyads who used home services to examine the impact of in-home respite care on caregiver burden. Propensity score matching was used to select 323 in-home respite service users matched with 646 nonusers as control groups (1:2 matching). The mixed effect model was applied to estimate the effects of receiving in-home respite care on caregiver burden. Results showed that compared with those of nonusers, caregiver burden scores of service users decreased significantly after receiving in-home respite care for more than 14 days (adjusted B = -0.14, SE = 0.05). The government should prioritize increasing the number of days of in-home respite care for those in need to reduce the caregiver burden.

The Effect of Ageist Behaviors on Home Care Workers' Job Satisfaction and Retention in Long-Term Care.

OBJECTIVES: This study aimed to examine how intrinsic and extrinsic factors of job satisfaction affect home care workers' intention to stay and determine whether ageist behaviors moderate the relation between job satisfaction and intention to stay. METHOD: We recruited 380 participants to complete measures of job satisfaction, ageist behaviors, and intention to stay. RESULTS: Monthly wages, extrinsic and intrinsic factors, and positive and negative ageist behaviors were significantly related to home care workers' retention. Both positive and negative ageist behaviors negatively moderated the relation between job satisfaction and retention. CONCLUSION: Home care workers' retention may be increased by providing reasonable extrinsic rewards and enhancing the intrinsic nature of the job itself. Reducing negative ageist behaviors and increasing positive ones for those with low job satisfaction could be related to higher retention. The harmful effects of positive behaviors should be addressed. These findings could contribute to workforce retention in long-term care.

Functional and Cognitive Impairments Increased Risks of Outcomes of Healthcare Utilization in Patients With Stroke Receiving Home and Community-Based Care in Taiwan.

Aim: Stroke is a leading cause of disability; however, little is known about the outcomes of the utilization of long-term care (LTC) recipients in Taiwan. This study aimed to quantify the burdens of disease of stroke survivors receiving LTC by evaluating the outcomes of their utilization including mortality, readmissions, and re-emergency within 1 year after diagnoses of strokes. Methods: By interlinkages among the national mortality registry, LTC dataset (LTC-CM), and the National Health Insurance Research Dataset (NHIRD), the outcomes and the factors associated with receiving LTC up to 1 year were explored. Patients were aged 50 years and over with an inpatient claim of the first diagnosis of stroke of intracerebral hemorrhage (ICH) and ischemic stroke during 2011-2016. Outcomes of the healthcare utilization include rehospitalization and re-emergency. Results: There were 15,662 patients with stroke who utilized the LTC services in the dataset among the stroke population in NHIRD. Stroke survivors receiving LTC showed no difference in clinical characteristics and their expected years of life loss (EYLL = 7.4 years) among those encountered in NHIRD. The LTC recipients showed high possibilities to be rehospitalized and resent to emergency service within 1 year after diagnosis. Apart from the comorbidity and stroke severity, both the physical and mental functional disabilities and caregiving resources predicted the outcomes of the utilization. Conclusions: For stroke survivors, both severe functional impairments and cognitive impairments were found as important factors for healthcare utilizations. These results regarding reserving functional abilities deserve our consideration in making the decision on the ongoing LTC policy reform in the aged society of Taiwan.

Can We Apply WHOQOL-AGE to Asian Population? Verifying Its Factor Structure and Psychometric Properties in a Convenience Sample From Taiwan.

Objectives: To translate and validate a recently developed quality of life instrument (WHOQOL-AGE) on geriatric population into Chinese. Method: Using cross-sectional observational design, the WHOQOL-AGE was conducted among older people through interview. Confirmatory factor analysis (CFA) was used to examine the factor structure and multigroup CFA used to examine the measurement invariance. Results: Through convenience sampling, 522 older adults (mean age = 73.42) participated in the study. Among them, 194 were males, 213 had an educational level at primary school or below, 398 were residing in the community, and 307 were aged 70 years or above. A bifactor structure (items Q1-Q8 are embedded in the factor 1; items Q9-Q13 embedded in the factor 2; and all the items embedded in an additional construct of QoL) was confirmed by the CFA in both the entire sample (χ2 = 25.4; df = 51; p = 0.999) and the subgroup sample with age 70 years or above (χ2 = 25.28; df = 51; p = 1.000). Multigroup CFAs results supported the measurement invariance for the WHOQOL-AGE across genders, having different educational levels, living in different settings and age groups. It also shows good known-groups validity. Conclusions: The promising psychometric properties of the WHOQOL-AGE were found in our convenience sample of older Taiwanese. The supported measurement invariance indicates that the older people in different conditions of gender, educational level, and living setting interpret the WHOQOL-AGE similarly. However, our results should be interpreted with cautious because of the sample representativeness.

Spousal Concordance in Dietary Behaviors and Metabolic Components, and Their Association: A Cross-Sectional Study.

This study aims to investigate spousal concordance in dietary behaviors, spousal concordance in metabolic components (MCs), and their association. A cross-sectional survey was conducted in Taiwan from November 2014 to May 2015. Matched-pair analysis, McNemar's test, logistic regression analysis, and stratified analysis were performed. A total of 901 pairs of spouses (1802 participants) were analyzed. Husbands were less likely to report intakes of high-fiber food (ORMP (matched pairs odds ratio) = 0.30, p < 0.0001), fish (ORMP = 0.74, p = 0.0128), biscuits or cakes (ORMP = 0.60, p < 0.0001), and fast food (ORMP = 0.65, p = 0.01) compared with their wives. Husbands had significantly higher odds of being overweight (ORMP = 2.34, p < 0.0001); and of having hypertension (ORMP = 2.14, p < 0.0001), hypercholesterolemia (ORMP = 1.75, p = 0.0007), hyperlipidemia (ORMP = 2.96, p < 0.0001), and one or more metabolic components (composite MCs) (ORMP = 2.50, p < 0.0001) compared with their wives. After adjusting for age and education, the spousal concordance in high-fiber food intake was inversely associated with the spousal concordance in composite MCs (aOR = 0.62, 95% CI = 0.44-0.88, p = 0.0074), whereas the spousal concordance in processed food intake was positively associated with the concordance in composite MCs (aOR (adjusted odds ratio) = 1.56, 95% CI (Confidence Interval) = 1.03-2.36, p = 0.034). An intervention study for couples with intakes of different fiber foods and/or processed foods is critical for future study, in order to test what kinds of fiber foods/processed foods are associated with the development of the spousal concordance of metabolic components.

Profile of Long-Term Care Recipients Receiving Home and Community-Based Services and the Factors That Influence Utilization in Taiwan.

In response to the irreversible aging trend, the Taiwan government has promoted the Long-Term Care (LTC) policy 1.0 launched in 2007 and the LTC policy 2.0 reform since 2016. This study aimed to explore the utilization of formal home and community-based care under LTC policy 1.0 to add scientific support for the on-going LTC policy 2.0 reform. METHODS: By using Andersen and Aday's behavioral model of healthcare utilization, the long-term care dataset was analyzed from 2013 to 2016. A total of 101,457 care recipients were identified after data cleaning. RESULTS: The results revealed that about 40.7% of the care recipients stayed in the care system for more than two years. A common factor influencing the length of home and community-based services (HCBS) utilization period included need factors, where more dependent recipients leave the LTC system regardless of their socio-economic status. However, the utilization period of non-low-income households is significantly affected by the level of service resources. CONCLUSION: For long-term care needs, the phenomenon of a short utilization period was concerning. This study adds information which suggests policy should reconsider care capacity and quality, especially for moderate to severely dependent recipients. This will allow for better understanding to help maintain care recipients in their own communities to achieve the goal of having an aging in place policy.

Goat Milk Consumption Enhances Innate and Adaptive Immunities and Alleviates Allergen-Induced Airway Inflammation in Offspring Mice.

Goat milk (GM), as compared to cow milk (CM), is easier for humans to digest. It also has antioxidant and anti-inflammatory effects and can improve minor digestive disorders and prevent allergic diseases in infants. It is unclear whether GM consumed in pregnant mothers has any protective effects on allergic diseases in infants. In this experimental study with mice, we found GM feeding enhanced immunoglobulin production, antigen-specific (ovalbumin, OVA) immune responses, and phagocytosis activity. The GM-fed mice had an increasing proportion of CD3+ T lymphocytes in the spleen. Splenocytes isolated from these animals also showed significantly increased production of cytokines IFN-γ and IL-10. More importantly, GM feeding during pregnancy and lactation periods can confer protective activity onto offspring by alleviating the airway inflammation of allergic asthma induced by mite allergens. There was a remarkably different composition of gut microbiota between offspring of pregnant mice fed with water or with milk (GM or CM). There was a greater proportion of beneficial bacterial species, such as Akkermansia muciniphila, Bacteroides eggerthii, and Parabacteroides goldsteinii in the gut microbiota of offspring from GM- or CM-fed pregnant mice compared to the offspring of water-fed pregnant mice. These results suggested that improving the nutrition of pregnant mice can promote immunological maturation and colonization of gut microbiota in offspring. This mother-to-child biological action may provide a protective effect on atopy development and alleviate allergen-induced airway inflammation in offspring.

The Implementation of Restorative Care and Factors Associated with Resident Outcomes in Long-Term Care Facilities in Taiwan.

This study aimed to analyze how restorative care is implemented in long-term care facilities and factors associated with resident outcomes in Taiwan. A one-group pre-test and post-test design was adopted in 24 long-term care facilities by collecting a sample of 310 participants at the baseline and 210 at six months. Participants were residents aged 65 or over, and were being constrained, used diapers, or were bedridden, or a combination of these. Their physical and mental functions were measured using Activities of Daily Living (ADLs), Instrumental Activities of Daily Living (IADLs), Mini-Mental State Examination (MMSE), Geriatric Depression Scale-15 (GDS-15), and EuroQol-5D (EQ-5D). Mean differences in the outcomes were analyzed, and mixed effect models were used to examine influencing factors. The results showed that most of the participants had good family support. However, participants with better family support were more likely to drop out. Improvements were found in the residents' outcomes on physical function, depression and quality of life. Social support was a significant influencing factor on most of the outcomes. In conclusion, restorative care was found to have positive effects on residents' physical function and helped maintain mental function. Sufficient support and communication between participants, families, and staff in facilities are key factors leading to positive outcomes.

The Effectiveness of Home Services in Taiwan: A People-Centered Approach.

Among available home and community-based services in Taiwan, there should be a focus on providing people with people-centered, value-based services. This study aims to follow up the people-centered health outcomes of care recipients and to examine the factors associated with to feedback for policy and practice in long-term care. A total of 9889 persons from the long-term care dataset were followed up for two years (T0⁻T4). The Cox Proportional Hazard Regression analyses to analyze mortality and the mixed effect models for health outcomes were used. Three classes among the care recipients were identified. Health profiles (HR = 1.46 and 2.56 for FI and FD compared with RI, p < 0.001), subsidy gap (HR = 1.01), and living status (HR = 0.88 for those living with spouse only) had a significant impact on mortality. The overall dropout rate was 52.3% at two years, and the health profiles at baseline significantly influenced the health outcome's change. The health heterogeneity matters and influences subsequent outcomes. To reach the goal of the HCBS, regular and exact monitoring of care recipients is crucial, while feedback regarding health outcomes and a greater focus on providing person-centered and responsive services in the community are also required.

Exploring factors influencing the work-related morale for certified nursing assistants in hospice care: A structural equation modeling study.

BACKGROUND: Certified nursing assistants (CNAs) in palliative care units often encounter the death of patients and undergo emotional burdens because of their altruistic practices. However, the influences of altruism and perceptions of death on the work morale of CNAs remain unclear. The fact that morale can be improved by modifying related factors justifies the necessity of a theoretical model of morale for CNAs. However, such a model is currently absent. Based on relevant literature, factors including altruism, social support, perceptions of death, and job satisfaction are related to morale through the mediation of job stress. AIM: This study was aimed toward determining the influencing factors and developing a structural model of morale with regard to CNAs working in palliative care units. DESIGN: The hypothesized model was tested in a cross-sectional design with structural equation modeling using AMOS 23. SETTING/PARTICIPANTS: A total of 413 CNAs from five hospice units in Taiwan participated in the survey. RESULTS: Goodness-of-fit indexes, including χ2/DF = 2.187, PGFI = 0.461, and PNFI = 0.462, among others, confirmed the modified model fit the data well. Altruism, social support, perceptions of death, and job satisfaction were negatively related to job stress (-0.238, -0.196, -0.204, and -0.131, respectively). Altruism and social support positively affected job satisfaction (0.635 and 0.553). Factors directly affecting morale included altruism, social support, job stress, and job satisfaction (0.837, 0.711, -0.244, and 0.540, respectively). The relationship between altruism and morale was the strongest among all the direct paths toward morale. Job stress was the major mediator in these relationships. CONCLUSION: Altruism is imperative for morale. The confirmed model is called the Five Constructs to Morale (5CM) model. These findings indicate the need to assess the levels of altruism and perceptions of death during the recruitment of CNAs. From the perspective of human resource management and organizational behavior, CNAs with a high level of altruism and a positive attitude toward death assure the well-being of end of life patients because of work involvement and commitment to the challenging work of hospice care. The cultivation of a supportive environment and coping strategies are suggested for the management of CNAs facing patient death. Hospice care decision makers should carefully assess morale levels among health professionals by applying the 5CM model. Identifying modifiable factors that can improve morale among nursing staff in hospice care to ensure work fulfillment and quality care merits emphasis in clinical practice. The establishment of effective strategies to facilitate the work morale of nursing staff is suggested for palliative care units. Morale improvement related task should be a global public health priority.

The effect of disability and depression on cognitive function and screening factors.

INTRODUCTION: There is increasing evidence that subtle losses in cognitive function may be symptomatic of a transition to early dementia. The objectives of this study were to: 1) test the effect of depressive symptoms and/or disability on cognitive impairment, 2) explore the interaction between depression and disability and the association with cognitive impairment, and 3) evaluate risk factors of health assessment to discriminate between elderly people with or without cognitive impairment. MATERIAL AND METHODS: The subjects were the community-dwellings aged 65 years and over who live in the sample city of southern Taiwan. 2734 persons were recruited by random sampling in the community, and the data was collected with face to face interviews by the training interviewers. RESULTS: The effect of disability on cognitive impairment is stronger than the effect in depression. It also implies the possibility that disability may mediate the association between depression and cognitive impairment. Screening for risk factors of cognitive impairment was defined in this study and may be feasible for general population. CONCLUSIONS: This study suggests that disability and depression assessments may serve as useful predictors of cognitive impairment. It is hoped that for elderly people, early assessment through screening factors could be arranged to this high-risk subgroup to reduce the risk of developing future dementia. Screening for functional disability and depressive symptoms would help to put management strategies in place that may reduce the associated cognition impairment burden.

What factors influence healthy aging? A person-centered approach among older adults in Taiwan.

AIM: The present study aimed to identify the health profiles of older adults by using latent class analysis to investigate health heterogeneity and to determine what factors predicted healthy aging among an oldest-old sample cohort that was followed up for 14 years in Taiwan. METHODS: Data were drawn from five waves (carried out in 1993, 1996, 1999, 2003 and 2007) of the Taiwan Longitudinal Study on Aging to examine the changes in health heterogeneity in a nationally representative oldest-old cohort of Taiwanese. Overall, data from a total of 11 145 observations of 3155 older adults were considered. The influential factors predicting health changes were analyzed by using a generalized estimating equation. RESULTS: The results showed that four health profiles were identified among the aging population observed in the Taiwan Longitudinal Study on Aging. With increasing age, the combined effects of the physical functioning, cognitive and emotional health, and comorbidities of older adults significantly impact their health changes. Apart from health deteriorating with age and sex disparities, educational and economic status, health behaviors, and social participation at the individual level were found to be the robust factors in predicting healthy aging. CONCLUSIONS: In considering what factors impact healthy aging, we suggest that a person-centered approach would be useful and critical for policy makers to understand the compositions of health profiles and the influencing factors in view of a life-course perspective. Based on the factors identified as influencing healthy aging at the individual level, it is imperative from a policy-making perspective to maximize opportunities for healthy aging.

Obesity risk class and asthma outpatient service utilization by the middle aged and elderly in Taiwan.

BACKGROUND: According to the estimates of the World Health Organization (WHO), there were about 300 million people in the world suffering from asthma in 2005. Among the risk factors of asthma is obesity, which was found to be significantly associated with asthma in recent decades. OBJECTIVES: In this study, we analyze the relationship between obesity risk class and asthma outpatient service utilization by the middle-aged and elderly in Taiwan. METHODS: Adopting data from the 2005 Nation Health Interview Survey (NHIS) and National Health Insurance Research Database (NHIRD), we first utilize latent class analysis (LCA) to identify obesity risk classes. Next, we utilize a logit and a negative binominal model to analyze the relationship between each obesity risk class and asthma outpatient service utilization. RESULTS: Results indicate that compared with the "overweight/obese with low consumption of vegetable/fruit and little exercise" class, the classes "normal-weight with high consumption of vegetable/fruit and moderate exercise" and "overweight/obese with high consumption of vegetable/fruit and moderate exercise" tend to have low probabilities and less number of visits of utilizing asthma outpatient services. CONCLUSIONS: Our results may constitute useful references for clinicians and government policy makers formulating strategies for asthma management and prevention. Better informed strategies for asthma management could, in turn, increase the efficiency of asthmatic patients' care, which could provide efficient assistance to the target group based on the obesity risk classes.
