Intervention to reduce loneliness among older adults in the community: Making friends with volunteers. Geriatr Gerontol Int 2024; 24 Suppl 1:240-245. [PMID: 38323733 DOI: 10.1111/ggi.14828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 01/17/2024] [Accepted: 01/22/2024] [Indexed: 02/08/2024]
Abstract
AIM This study aimed to examine the effects of providing a program that introduced volunteers to make friends with older adults to reduce loneliness and increase loneliness literacy. METHODS Eight community development associations in Taiwan participated in the study. In the first stage, older people living alone or with only a spouse, or those with a family, but without substantial interactions, were screened for loneliness. Older adults with a higher risk of loneliness were given priority to be invited to participate in this intervention. This 3-month intervention program was designed by each community development association and delivered at the older adults' homes. A total of 87 older persons completed both waves of the interviews. RESULTS Loneliness was reduced (UCLA-6 Loneliness Scale scores decreased from 13.5 to 11.6), and loneliness literacy improved (loneliness literacy scores increased from 38.9 to 42.0) compared with what it was before the program. In a generalized linear model, when controlling for covariates, loneliness was reduced, but not significantly (B = -0.934, P > 0.05), whereas loneliness literacy improved significantly for older participants (B = 2.088, P < 0.05). CONCLUSIONS Making friends with older adults who are lonely might improve their loneliness literacy. Geriatr Gerontol Int 2024; 24: 240-245.

Attitudes toward active aging and their association with social determinants and views on older adults in Japan: a cross-sectional study. BMC Geriatr 2024; 24:140. [PMID: 38326743 PMCID: PMC10851495 DOI: 10.1186/s12877-024-04711-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 01/16/2024] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND Globally, the population of older adults has greatly increased, and active aging-whereby older adults can live healthy and fulfilling lives-is considered crucial for a sustainable society. However, the concept and practice of active aging are highly debated because it is unclear how people perceive active aging. This study explored Japanese people's attitudes toward active aging (ATAA) and examined the associations between ATAA scores and sociodemographic variables, views on older adults, and self-rated life and health. METHODS This study used data obtained from an online survey that originally targeted adults of all generations in Taiwan, South Korea, and Japan. In this study, we used only data from Japanese participants to elaborate on factors associated with ATAA in Japan. We conducted a one-way analysis of variance test and multiple linear regression analysis to evaluate the associations between the ATAA scores of 506 Japanese individuals and sociodemographic variables, views on older adults, and self-rated life and health. RESULTS The sample comprised 171 females and 335 males. The mean (± SD) ATAA score of the 506 respondents was 138.8 (± 20.80). Females had a significantly higher ATAA score than males (144.02 versus 136.13, F = 26.29, p < 0.001). The respondents with higher education attainment, religious beliefs, better views on older adults, and better self-rated health were more likely to have a positive ATAA score (B: 3.83, 95% CI: 0.11, 7.56; B: 4.31, 95% CI: 0.93, 7.69; B: 2.07, 95% CI: 1.61, 2.53; B: 2.87, 95% CI: 0.92, 4.82, respectively). Being male, single (i.e., never married, divorced, or widowed) and other non-married marital statuses, and satisfied with one's financial condition were negatively associated with ATAA (B: -8.73, 95% CI: -12.49, -4.96; B: -5.47, 95% CI: -9.07, -1.86; B: -2.04, 95% CI: -3.99, -0.09, respectively). CONCLUSIONS This study identified that females have more positive ATAA than males. Better views on older adults are a possible contributing factor that promotes ATAA among Japanese people. Our findings provide useful evidence that an approach towards those who are male, single, and economically satisfied is needed so that they have a positive attitude toward aging in Japan. It is necessary to address ageism and develop an environment in which individuals can expect to age actively.

Effects of social capital on healthcare utilization among older adults in Indonesia. Health Promot Int 2023; 38:daad104. [PMID: 37715938 DOI: 10.1093/heapro/daad104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 09/18/2023] Open
Abstract
Social capital potentially affects older adults' access to healthcare services. However, the effects of social capital on the use of various types of healthcare services using longitudinal data have yet to be explored. This study aimed to examine the effects of structural and cognitive social capital on different types of healthcare utilization by older adults in Indonesia. Data were from the Indonesian Family Life Survey (waves 4 and 5) in 2007 and 2014. The sample consisted of participants aged 60 years and older who completed both waves (n = 1374). Healthcare utilization by older adults assessed health posts (posyandu), health checkups, outpatient care and hospital admissions. Social capital consisted of neighborhood trust and community participation. Generalized estimating equation models were used for the analysis. Older adults with high community participation had a higher likelihood of using preventive care in posyandu (OR = 5.848, 95% CI = 2.585-13.232) and health checkup visits (OR = 1.621, 95% CI = 1.116-2.356). Meanwhile, neighborhood trust was related to a higher probability of hospital admissions (OR = 1.255, 95% CI = 1.046-1.505). Social capital significantly affects older adults' preventive and treatment healthcare utilization. Maximizing the availability of social participation and removing barriers to access to preventive and medical care in an age-friendly environment are suggested.

Abstract
Indonesia faces the double burdens of childhood obesity and malnutrition. A family's socioeconomic status has been suggested to be one of the most influential factors contributing to childhood nutritional problems. This study aimed to: 1) identify the distinct trajectories of family economics; and 2) assess whether a family's economic trajectory influences children's body mass index (BMI). We analyzed trajectory patterns of family economic levels from 1997 to 2015 among 846 children aged under 3 years in 1997 using data from Indonesian Family Life Surveys. Trajectory patterns were identified with Group-Based Trajectory Modeling using the traj plug-in in STATA software. The BMI was classified according to 2007 World Health Organization growth standards. Adjusted relative risk ratios (aRRRs) of family economic level trajectories and children's BMI were calculated using multinomial logistic regressions. We identified three distinct trajectories of family economic level: stable poorest, stable middle, and increasing richest. In the total sample, there were no significant relationships between a family's income trajectory and children's BMI in the adjusted models. A significant relationship existed for male children, but not for female children, of compared to the poorest family trajectory group, male children in the increasing richest trajectory group were more likely to be overweight/obese (aRRR 6.1, 95% confidence interval: 1.22-30.62) after adjusting for age and BMI. The present results highlight the importance of early interventions to minimize the potential adverse impacts of excessive BMI later in adulthood.

Association between Hypertension and Stroke Recurrence as Modified by Pro-oxidant-Antioxidant Balance: A Multi-Center Study. Nutrients 2023; 15:nu15102305. [PMID: 37242188 DOI: 10.3390/nu15102305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 05/10/2023] [Accepted: 05/12/2023] [Indexed: 05/28/2023] Open
Abstract
BACKGROUND Hypertension and oxidative stress are involved in the pathophysiological mechanism of stroke. We aimed to investigate the modification impact of the pro-oxidant-anti-oxidant balance (PAB) on the association between hypertension and stroke recurrence (SR). METHODS A cross-sectional design was conducted from December 2019 to December 2020 in 951 stroke patients in six hospitals across Vietnam. Hypertension was defined using antihypertensive medication or systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg. PAB was estimated using weighting methods based on smoking, drinking, and overweight/obesity with pro-oxidant capacity, diet quality, fruit intake, vegetable intake, and physical activity with antioxidant capacity. The higher PAB scores indicated a beneficial balance shifting toward antioxidant dominance. SR was diagnosed by neurologists. Moreover, sociodemographic and health conditions were included as covariates. Multiple logistic regression analyses were used to explore the associations and interactions. RESULTS The hypertension and SR proportions were 72.8% and 17.5%, respectively. hypertension was associated with an increased SR likelihood (odds ratio (OR) = 1.93; p = 0.004), whereas a higher PAB score was associated with a lowered SR likelihood (OR = 0.87; p = 0.003). Moreover, hypertension interacting with every one-point increment of PAB was associated with a lowered SR likelihood (OR = 0.83; p = 0.022). CONCLUSIONS The harmful impact of hypertension on SR could be alleviated by PAB. The interplay of health behaviors should be highlighted in the intervention strategies for stroke prevention.

Abstract
As Taiwan heads steadily toward becoming a super-aged society, the impact of aging on society at large will become increasingly extensive and intense. Therefore, establishing an age-friendly environment in Taiwan is an important issue for the government. Feasible guidelines for age-friendly communities are necessary to ensure that appropriate social welfare measures are enacted to achieve the national goal of aging in place. The first draft of the guideline questionnaire was developed based on the World Health Organization Guidelines for Age-Friendly Cities, a literature review, and input from seven experts on aging. Three rounds of questionnaire surveys were then conducted to assess the correctness, appropriateness, and importance of the guidelines, with amendments, additions, and deletions made based on the experts' responses until they all expressed a high degree of satisfaction with all of the guidelines. The Taiwan Age-friendly Community Guidelines document discussed in this article includes 38 guidelines that address the eight facets of "outdoor spaces and buildings", "transportation", "housing", "social participation", "respect and social inclusion", "civil participation and employment", "communication and information", and "community support and health services". The guidelines document describes in detail the goals of age-friendly communities in specific and easy-to-understand terms. Moreover, it provides a reference for frontline personnel in the community to promote age-friendly environs.

Abstract
OBJECTIVES The purpose of this study was to examine the effects of different types and levels of social capital and emotional well-being in older adults in Indonesia by a longitudinal data. METHODS The fourth and the fifth waves of Indonesian Family Life Survey data were used for this study. The participants aged 60 years or older who participated in both waves were included for analysis (n = 1374). Depressive symptoms and happiness were used to assess emotional well-being. Cognitive social capital (neighborhood trust) and structural social capital (participating in arisan, community meetings, volunteers, village improvement programs, and religious activities) were the main independent variables. The generalized estimating equations model was used for analysis. RESULTS Participation in arisan (B = -0.534) and attending religious activities (B = -0.591) were related to lower depressive symptoms, but the effect of religious activities would offset over time. Both a low or high social participation showed protective effects on depressive symptoms at the intercept and the time slope. Having higher neighborhood trust was related to more chance of feeling very happy (OR = 1.518). CONCLUSION Structural social capital is protective from depressive symptoms, while cognitive social capital contributes to happiness. Facilitating social participation and improving neighborhood trust through policies and programs is suggested to promote emotional well-being for older people.

Abstract
This study developed indicators of age-friendliness for communities in Taiwan that conform to international standards by referring to the World Health Organization Checklist of Essential Features of Age-Friendly Cities and Taiwan's existing indicators. The first stage of the research was based on the WHO's framework and involved a literature review to identify candidate indicators. In the second stage, experts' opinions were collected through a modified Delphi method, and the indicators were screened and revised on the basis of their importance, community enforceability, and generality. The third stage focused on practical feasibility. External parties were invited to offer their opinions regarding the indicators, which were adjusted accordingly. After three rounds of review and re-examination based on the modified Delphi method, the final set of indicators comprised five core indicators and five optional indicators. These indicators can be used to monitor various aspects of communities and determine their age-friendliness.

Abstract
BACKGROUND Loneliness has become a significant public health concern for older people. However, little is known about the association of loneliness, loneliness literacy, and changes in loneliness during the COVID-19 pandemic with mental well-being. The purpose of this study was to explore whether loneliness literacy is related to a lower risk of loneliness, increased loneliness during the COVID-19 pandemic, and improved mental well-being for community-based older adults. METHODS A telephone survey was conducted to collect data from older adults aged 65 years or older in Taiwan (n = 804). Loneliness, change in loneliness during COVID-19, and loneliness literacy were the main variables. Mental well-being was assessed by depressive symptoms and life satisfaction. Related factors included personal level (demographics, health conditions, health behaviors, and problem-focused/ emotion-focused coping strategies), interpersonal level (marital status, living arrangements, social support, social participation, leisure activities, and social interactions during COVID-19), and societal level (areas and regions) factors. RESULTS Four dimensions of loneliness literacy were identified by factor analysis: self-efficacy, social support, socialization, and in-home support. Self-efficacy and in-home support were related to lower loneliness. Lower self-efficacy, higher social support, and higher socialization were related to changes (increases) in loneliness during COVID-19. In-home support may prevent depressive symptoms, while self-efficacy was beneficial for better life satisfaction. In addition, emotion-focused coping may increase loneliness during COVID-19, while satisfaction with family support would be a protective factor against loneliness. CONCLUSION Loneliness literacy is related to loneliness and increased loneliness during the COVID-19 pandemic. Building up an age-friendly community with embedded services/information and learning positive coping and mental resilience strategies are suggested.

Abstract
Whether changes in health behaviors can improve successful aging has not been well explored. The purpose of this study was to assess the effects of health-related behaviors and changes on successful aging in Indonesian older adults. Data were from the fourth and fifth waves of the Indonesia Family Life Survey (IFLS), the participants were aged 60 years and older and who completed both waves (n = 1289). Successful aging indicators were defined as no chronic diseases, no physical function difficulties, no depressive symptoms, intact cognitive function, with social support, and with social participation. Health-related behaviors focused on smoking, physical activities, and protein intake. A logistic regression analysis was conducted. The overall successful aging rate in 2007 was 23.6%, and it had decreased to 5.6% by 2014. There were gender differences in smoking, physical activities, and behavioral changes, including promoting increased physical activity, no smoking/smoking cessation, and adequate protein intake by older adults. Quitting smoking, performing medium physical activity, and increasing protein intake were protective factors for successful aging, but the effects of behavioral changes differed by gender. Health-related behaviors and changes may impact successful aging among older adults. A healthy lifestyle is suggested to be adopted as early as possible in one's life course.

Abstract
BACKGROUND Individual and environmental factors have been found to be related to cognitive function. However, few studies have examined the longitudinal effects of both individual and environmental factors over time. The purpose of this study was to examine the effects of individual and environmental factors over time on older people's cognitive function. METHODS Nationally representative panel data from the Taiwan Longitudinal Survey on Aging 1999-2015 (n = 6349 persons, observations = 12,042) were used. City-level indicator data were sourced from the government. A multilevel mixed linear model analysis was conducted. RESULTS Better cognitive function was significantly related to individuals' work, ethnicity, younger age, higher education level, better self-rated health, higher level of emotional support received, being more religious, higher economic satisfaction, and living in the cities with higher population densities. Education and social connectedness were protective factors over time. CONCLUSION Socioeconomics and social connectedness are related to cognitive function. A more social integrated lifestyle and financially secure living is suggested in the policy.

Abstract
The purpose of this study was to examine the association between age-friendliness of a city, loneliness and depression moderated by internet use among older people during the coronavirus disease 2019 (COVID-19) pandemic. The survey was from ‘The 2020 Survey of Needs Assessment for a Safe Community and Age-Friendly City’ in Xinyi District, Taipei, which was conducted by face-to-face interviews with community-based older adults who were aged 65 and above from one district of Taipei City from May to June 2020 (n = 335). Partial least square structural equation modeling and the SPSS PROCESS macro were used for data analysis. Two domains of an age-friendly city (housing and community support and health services) were found to be associated with reduced loneliness, while one (respect and social inclusion) was associated with decreased depression. The age-friendliness of cities mitigates depression through moderator (internet use) and mediation (loneliness) mechanisms. Although some age-friendly domains of the city reduced loneliness and depression directly, the age-friendliness–loneliness-depression mechanism held true only for older adults who used the internet and not for nonusers. Maintaining the age-friendliness of an environment is beneficial to mental health, and internet use is a necessary condition to gain optimum benefits from age-friendly initiatives. Policy suggestions are discussed.

Abstract
According to continuity theory, successful aging is promoted when older people are able to continue familiar activities as a way to maintain self-identity. The purpose of this study was to examine the importance of both external resources provided by Taipei city and older adults’ internal resources in internal and external continuity and life satisfaction. The data were from the 2019 Taipei City Senior Citizen Condition Survey acquired through face-to-face interviews. Only the community-based sample without disability was included in the analysis (n = 1494). Structural equation modeling was used for the analysis. Both internal and external resources significantly promoted internal continuity (physical activity, Internet use, and lifelong learning) and external continuity (work, social connectedness, and social participation), and the effects of personal resources were larger. External continuity was positively related to life satisfaction. The effects of external resources on continuity and life satisfaction were stronger in older women than in older men. Age-friendly cities may provide support for activity continuity and promote well-being for older people. Policy suggestions are discussed.

Abstract
The purpose of this study was to examine the associations between cognitive function, the city’s social environment, and individual characteristics of older adults. The individual data of older people were from the Nutrition and Health Survey in Taiwan 2013–2016. The participants who were aged 65 and above were included in the analysis (n = 1356). City-level data were obtained for twenty cities in Taiwan. The data of city-level indicators were from governmental open data and Taiwan’s Age Friendly Environment Monitor Study. A multilevel mixed-effect model was applied in the analysis. Population density, median income, safety in the community, barrier-free sidewalks, high education rate of the population, low-income population rate, household income inequality, and elderly abuse rate were related to cognitive function in the bivariate analysis. When controlling for individual factors, the city’s low-income population rate was still significantly related to lower cognitive function. In addition, the participants who were at younger age, had a higher education level, had a better financial satisfaction, had worse self-rated health, had higher numbers of disease, and had better physical function had better cognitive function. Social and built environments associated with cognitive function highlight the importance of income security and the age friendliness of the city for older adults. Income security for older people and age-friendly city policies are suggested.

Abstract
OBJECTIVES This study constructed an Active Aging Index (AAI) for Vietnam and compares Vietnam's AAI with those of China, Korea, Taiwan, and 28 countries in the European Union. METHODS A survey of 1,105 people aged 55 or above in three provinces from the northern, central, and southern parts of Vietnam was conducted. Active aging was measured using the AAI; its 22 indicators were grouped into four domains: employment, social participation, independent/healthy/secure living, and enabling environments. RESULTS Of the 32 countries reviewed, Vietnam ranked 11th. It ranked high for employment (1st) and social participation (5th) but low for independent/healthy/secure living (32nd) and enabling environments (26th). CONCLUSION Three policy priorities were identified: maintaining a high preference-driven social and workforce participation rate among older adults; promoting medical care and healthy behaviors among older adults; and improving other poorly performing aspects of active aging, including voluntary activities, poverty risk, Internet usage, and lifelong learning.

Abstract
The purpose of this study was to examine the relationship between knowledge and attitudes towards dementia among adults. A cross-sectional online survey with purposive sampling was conducted in four district health centers in Taichung, Taiwan, in 2018. Knowledge was measured by the Taiwanese version of the Dementia Knowledge Assessment Scale. Attitudes towards people with dementia were measured by four kinds of feelings: discomfort, shame, avoidance, and fear. In total, 347 persons completed the questionnaire. Knowledge of dementia was modest. Higher education, a care-related background, chronic health conditions, experience caring for people with dementia, and knowledge of family history were related to higher knowledge of dementia. Attitudes towards people with dementia were grouped into four clusters: uncomfortable (22.2%), ashamed (2.6%), unfriendly (22.5%), and non-negative (52.7%). Knowledge of dementia was significantly related to the ashamed cluster but not to the other clusters. Lower education, a lack of caring experience, and a lack of knowledge of family history were related to uncomfortable feelings, and poorer financial satisfaction was related to uncomfortable, afraid, and avoidant feelings. The open-question expression of feelings towards dementia was more likely to be negative (55.3%). The public should be educated on knowledge of and friendly attitudes towards dementia.

Regular exercise and the trajectory of health-related quality of life among Taiwanese adults: a cohort study analysis 2006-2014. BMC Public Health 2019; 19:1352. [PMID: 31646989 PMCID: PMC6806516 DOI: 10.1186/s12889-019-7662-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Accepted: 09/20/2019] [Indexed: 12/26/2022] Open
Abstract
Background Physical activity is related to health-related quality of life, but little evidence from multiple waves of panel data in Asian countries area available. This study aims to explore the impacts of different degree of regular exercise on the trajectories of physical and mental dimensions of health-related quality of life (HRQOL) for community-dwelling Taiwanese adults during 2006–2014. Methods Data were derived from the “Landseed Integrated Outreaching Neighborhood Screening (LIONS)” study, with 6182 adults enrolled at the baseline and subsequently followed up to three times till 2014. Linear mixed-effects modeling approach was employed to evaluate the growth curve models of HRQOL (with 16,281 observations) by linear & quadratic time effects, regular exercise (5-level moderate-intensity physical activity), and major influential factors of HRQOL. Results Regular exercise showed significantly positive dose-response effects on physical HRQOL (β =1.27~2.54), and regular exercise of 150 min or more showed positive effects on mental HRQOL (β = 1.55~2.03). Besides, irregular exercise could also improve both physical and mental HRQOL (β = 1.27 & β = 0.87). However, such effects were not significant over time (at time slope) on HRQOL. In addition, physical and mental HRQOL improved across time (β = 1.01 and 1.49, respectively), but the time quadratic effect would significantly offset a little bit on physical dimension (β = − 0.22). Moreover, being female, increasing age, living alone, or poorer health status were related to lower physical HRQOL; and being younger, living alone, or poorer health status were associated with lower mental HRQOL. Conclusions The positive dose-response relationship between regular exercise and HRQOL or its domains was demonstrated for community-dwelling Taiwanese adults. Thus, a regular exercise habit (better ≧150 min per week) is advised for community-based healthcare professionals and the government to incorporate into health promotion strategies and plans.

LTC 2.0: The 2017 reform of home- and community-based long-term care in Taiwan. Health Policy 2019; 123:912-916. [PMID: 31455563 DOI: 10.1016/j.healthpol.2019.08.004] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Revised: 07/01/2019] [Accepted: 08/12/2019] [Indexed: 11/18/2022]
Abstract
Taiwan planned to establish a social insurance-based long-term care system in 2016. However, due to the change in political parties that year, it was decided that Taiwan's long-term care policy would remain a tax-based financing scheme. The new policy focuses on providing home- and community-based service (HCBS); a three-layer HCBS service network within towns and districts was set to provide the 17 types of services in the HCBS spectrum, including preventive care. The reform was criticized as being too restrictive and lacking flexibility. However, the HCBS service spectrum has been widened, the target group has been enlarged, and thus HCBS utilization has increased. A rolling amendment has continued into 2018: the HCBS system requirement has been eased, and a new capitalized fee-for-service payment system has been launched. This paper discusses the analysis of the policy reform.

Abstract
UNLABELLED Osteoporosis is a well-known bone disorder affecting people worldwide. Patients with osteoporosis have an increased risk of bone fracture. This study provides new information on the risk of developing osteoporosis post burn injury and the risk of fracture among those with osteoporosis developed. INTRODUCTION The relationship between burn injury and hip fracture risk is unclear. Population-based evaluation on relationships between burn injury and osteoporosis development and subsequent fractures is limited. We conducted a retrospective cohort study as the investigation. METHODS From the insurance data of Taiwan, we established a cohort of 43,532 patients with a burn injury in 2000-2012 and a comparison cohort of 174,124 individuals without such an injury, frequency matched by sex, age, and diagnosis date. Both cohorts were followed up to the end of 2013 to evaluate the occurrence of osteoporosis and hip fracture. RESULTS The incidence of osteoporosis was greater in the burn cohort than in the comparison cohort (6.40 vs. 4.75 per 1,000 person-years) with an adjusted IRR of 1.35 (95% confidence interval = 1.32-1.39). The incidence rates in both cohorts were greater in women than in men, increased with age, income, and Charlson comorbidity index. Patients with burns involving 20%-49% of total body surface area and with burns confined to the lower/upper limbs had the greatest incidence rates, 8.32 and 8.58 per 1,000 person-years, respectively. Osteoporosis incidence increased further to 22.7 per 1,000 person-years for burn victims with comorbid diabetes. The risk of fracture was over five-fold greater for burn victims with osteoporosis developed than for comparisons without osteoporosis. CONCLUSION Patients who have a burn injury deserve prevention intervention to reduce the risk of osteoporosis and fracture.

Abstract
Community care centres (CCCs) are widespread across Taiwan and have provided health promotion and social activities for older people in communities since 1995. The purpose of this study was to describe the status of the delivery and management of CCCs for older people, and to explore the effects of individual factors and the organisational factors on the health-related outcome of older people's participation in CCCs. The sample was taken from participants at CCCs in Taichung, Taiwan. Twenty-five CCCs participated in the study. The managers and the elderly participants of CCCs underwent face-to-face interviews. In total, 417 elderly participants and 25 chiefs completed the face-to-face interviews. The participants reported that self-reported health, sleep quality, memory, family relationships, care for health, and health literacy improved after they participated in the programme. There were no consistent organisational factors related to the outcomes. However, management style was related to sleep quality improvement and staffing getting paid was related to family relationship improvement. Policy recommendations are provided.

Abstract
Background: Successful aging has been the paradigm of old-age life. The purpose of this study was to implement and evaluate a cross-disciplinary intervention program using two approaches for community-based older adults in Taichung, Taiwan. Methods: The content of the intervention included successful aging concepts and preparation, physical activity, chronic disease and health management, dietary and nutrition information, cognitive training, emotional awareness and coping skills, family relationship and resilience, legal concepts regarding financial protection, and Internet use. The traditional person-to-person (P2P) intervention approach was implemented among participants at urban centers, and the personal-and-digital (P&D) intervention approach was implemented among participants at rural centers; before the P&D group received the intervention, participants were assessed as the control group for comparison. Results: Healthy behavior and nutrition improved for the P2P group, although not significantly. Strategies for adapting to old age and reducing ineffective coping were significantly improved in the P2P group. The ability to search for health information improved in the P&D group, and knowledge of finance-related law increased in the P2P group. Conclusion: A continuous, well-designed and evidence-based intervention program is beneficial for improving the health of older adults, or at least delaying its decline.

Abstract
UNLABELLED This work aimed to evaluate the hip fracture risk for patients with burn injury. A total of 16,430 patients with burn injury had an adjusted hazard ratio of 1.54 to encounter a hip fracture, compared with controls without the injury. These results encourage future studies focusing on mechanisms leading to fracture associated with burn injury. INTRODUCTION The relationship between burn injury and hip fracture risk is unclear. We conducted a retrospective cohort study to investigate this relationship. METHODS From insurance data of Taiwan, we identified a cohort with 16,430 burn patients in 2000-2010 and a comparison cohort of 65,716 persons without the history of burn, frequency matched by sex, age, and diagnosis date. Both cohorts were followed up to the end of 2011 to evaluate the risk of hip fracture. RESULTS Patients with burn injury were 1.62-fold more likely than comparisons to encounter a hip fracture (6.95 vs. 4.28 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.54 (95% confidence interval (CI) = 1.40-1.68). The fracture incidence increased with age and is slightly greater for women than for men in both cohorts. The fracture risk was greater for patients with burn in the eyes, face, and head with an incidence of 7.14 per 1000 person-years, or an aHR of 2.09 (95% CI = 1.53, 2.86). Diabetes and osteoporosis were also associated with an increased hip fracture risk. CONCLUSION Burn injury is associated with an increased risk of hip fracture. Diabetes and osteoporosis are associated with an enhanced risk.

Abstract
The modulation instability (MI) is a universal mechanism that is responsible for the disintegration of weakly nonlinear narrow-banded wave fields and the emergence of localized extreme events in dispersive media. The instability dynamics is naturally triggered, when unstable energy sidebands located around the main energy peak are excited and then follow an exponential growth law. As a consequence of four wave mixing effect, these primary sidebands generate an infinite number of additional sidebands, forming a triangular sideband cascade. After saturation, it is expected that the system experiences a return to initial conditions followed by a spectral recurrence dynamics. Much complex nonlinear wave field motion is expected, when the secondary or successive sideband pair that is created is also located in the finite instability gain range around the main carrier frequency peak. This latter process is referred to as higher-order MI. We report a numerical and experimental study that confirms observation of higher-order MI dynamics in water waves. Furthermore, we show that the presence of weak dissipation may counterintuitively enhance wave focusing in the second recurrent cycle of wave amplification. The interdisciplinary weakly nonlinear approach in addressing the evolution of unstable nonlinear waves dynamics may find significant resonance in other nonlinear dispersive media in physics, such as optics, solids, superfluids, and plasma.

Abstract
PURPOSE This study was to implement and evaluate a successful aging intervention program for middle-aged private insurance beneficiaries. METHODS The participants were recruited from the staff and middle-aged clients for the experimental and control groups of a private insurance company. The two client (experimental and control) groups were matched by comparable age groups, gender, education, and purchased insurance types. The intervention program provided for the staff and the experimental group consisted of a series of educational courses on the topics about successful aging and preparation for 4 months. In total, there were 40 staff members, in addition to the 74 members of the experimental group and 60 members of the control group participating in the study. RESULTS After the intervention, the rate of physical activity and exercise significantly improved for the staff and for the intervention group. There were significant improvements in behaviors associated with doing exercise and living a less sedentary lifestyle and in the utilization of health examinations, and improvements in fitness and blood pressure. CONCLUSION The successful aging intervention program significantly improved awareness of successful aging, exercise behavior and fitness.

Abstract
BACKGROUND With the goal of in vivo cultivation of human hepatocytes that have not been sufficient in full differentiation in vitro, the advantage of neonatal thymectomy was verified on expansion of xenogeneic human hepatocyte in the micro-miniature pig (MMP). METHODS The thymus was excised immediately after the birth of the MMPs via cesarean section. Newborns were fed by artificial feeding under specific pathogen-free conditions. The thymectomized and nonthymectomized littermates were transplanted with human hepatocytes via a portal vein with or without partial hepatectomy at the MMP adult stage. RESULTS The growth of thymectomized MMPs and the sham operated littermates was not significantly different; the former weighed 1.98 ± 0.30 kg (average ± standard deviation, n = 4) and the latter weighed 2.28 ± 0.39 kg (n = 4) at 1 month of age, and 17.48 ± 1.92 kg and 16.75 ± 2.68 kg at 12 months of age. Blood thymosin α1 concentrations in the thymectomy group were significantly lower than in the control group (0.22 ± 0.05 ng/mL vs 0.46 ± 0.16 ng/mL; n = 4, 12 months old, P = .029). After human hepatocyte transplantation, human albumin levels were detectable on day 28 in the peripheral blood of the thymectomy plus hepatectomy group (14.3 ± 4.9 ng/mL [± range, n = 2]) but were not detectable even on day 21 in the control group. CONCLUSIONS Neonatal thymectomy was successfully achieved in infantile MMPs born via cesarean section. These pigs were considered to be an ideal in vivo bioreactor for human hepatocytes.

Abstract
Instabilities are common phenomena frequently observed in nature, sometimes leading to unexpected catastrophes and disasters in seemingly normal conditions. One prominent form of instability in a distributed system is its response to a harmonic modulation. Such instability has special names in various branches of physics and is generally known as modulation instability (MI). The MI leads to a growth-decay cycle of unstable waves and is therefore related to Fermi-Pasta-Ulam (FPU) recurrence since breather solutions of the nonlinear Schrödinger equation (NLSE) are known to accurately describe growth and decay of modulationally unstable waves in conservative systems. Here, we report theoretical, numerical and experimental evidence of the effect of dissipation on FPU cycles in a super wave tank, namely their shift in a determined order. In showing that ideal NLSE breather solutions can describe such dissipative nonlinear dynamics, our results may impact the interpretation of a wide range of new physics scenarios.

Abstract
OBJECTIVE To assess the efficacy of septoplasty and the correlation between the subjective evaluations of a visual analogue scale (VAS) and the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire and active anterior rhinomanometry of the nasal airway after septoplasty. DESIGN A retrospective, individual cohort study. SETTING Ear, Nose and Throat Department, Taipei City Hospital, Taipei, Taiwan. PARTICIPANTS Fifty patients with chronic nasal obstruction were enrolled in the study. All 50 patients underwent septoplasty because of nasal septal deviation. Another 28 patients without nasal symptoms served as controls. MAIN OUTCOME MEASURES VAS, NOSE and active anterior rhinomanometry were used to measure the sensation of nasal obstruction. All measurements were performed in both groups preoperatively and then repeated on three postoperative visits (3, 6 and 12 months). RESULTS The mean VAS score, NOSE score and the nasal resistance in the narrow side of the nose in the study group showed reduced symptoms at 3, 6 and 12 months postoperatively compared with the respective preoperative measurements (P < 0.001, all). The VAS and NOSE scores did not significantly correlate with total nasal resistance preoperatively or postoperatively. The VAS and nasal resistance in the obstructed nasal cavity correlated significantly preoperatively (P < 0.05), but not postoperatively. CONCLUSIONS The subjective and objective symptoms of nasal obstruction had improved 1 year after septoplasty. A significant correlation between VAS scores and nasal resistance in the narrow side of the nose was found before surgery. The subjective and objective measurements of nasal obstruction lacked significant correlation postoperatively.

Abstract
AIM This aim of this study was to examine the relationship between the utilisation of general health examinations and health and a healthy lifestyle. METHODS The data were from a 5-wave panel of older Taiwanese people. Health was defined as the absence of chronic diseases and physical function difficulties. A healthy lifestyle included no smoking, no alcohol consumption and engaging in regular exercise. Generalised linear modelling was applied. RESULTS The individuals with more chronic diseases were more likely to undergo health examinations, but the rate of change declined over time. Having more physical function disabilities may reduce the likelihood of undergoing health examinations. Individuals who engaged in regular exercise were more likely to undergo health examinations. CONCLUSION Health examination utilisation is related to health and healthy lifestyle among older people.

Abstract
BACKGROUND AND OBJECTIVE Periodontitis involves progressive loss of alveolar bone around the teeth. Hence, automatic alveolar bone-loss (ABL) measurement in periapical radiographs can assist dentists in diagnosing such disease. In this paper, we propose an effective method for ABL area localization and denote it as ABLIfBm. METHOD ABLIfBm is a threshold segmentation method that uses a hybrid feature fused of both intensity and texture measured by the H-value of fractional Brownian motion (fBm) model, where the H-value is the Hurst coefficient in the expectation function of a fBm curve (intensity change) and is directly related to the value of fractal dimension. Adopting leave-one-out cross validation training and testing mechanism, ABLIfBm trains weights for both features using Bayesian classifier and transforms the radiograph image into a feature image obtained from a weighted average of both features. Finally, by Otsu's thresholding, it segments the feature image into normal and bone-loss regions. RESULTS Experimental results on 31 periodontitis radiograph images in terms of mean true positive fraction and false positive fraction are about 92.5% and 14.0%, respectively, where the ground truth is provided by a dentist. The results also demonstrate that ABLIfBm outperforms (a) the threshold segmentation method using either feature alone or a weighted average of the same two features but with weights trained differently; (b) a level set segmentation method presented earlier in literature; and (c) segmentation methods based on Bayesian, K-NN, or SVM classifier using the same two features. CONCLUSION Our results suggest that the proposed method can effectively localize alveolar bone-loss areas in periodontitis radiograph images and hence would be useful for dentists in evaluating degree of bone-loss for periodontitis patients.

Abstract
UNLABELLED BACKGROUND/STUDY CONTEXT: This study aimed to identify the different trajectories of frailty and factors related to frailty among older adults over time. METHODS Data were obtained from a five-wave panel composed of older Taiwanese adults from 1993 to 2007 (N = 2306). Frailty was defined as the presence of three or more of the following criteria: shrinking, weakness, exhaustion, slowness, and low physical activity. A group-based model of trajectory analysis was applied with time-dependent and time-independent variables. RESULTS Three trajectory groups were identified: maintaining nonfrailty, developing frailty, and high risk of frailty. Being female, older, and having a lower level of education were risk factors for being in the developing frailty group or high risk of frailty group. Physical risk factors and psychological factors were associated with frailty within each group. Higher financial satisfaction and social participation were protective factors from frailty for the developing frailty group and high risk of frailty group, respectively. CONCLUSION Older adults should promote their health physically, psychologically, and socially.

Abstract
BACKGROUND The significance of physical activity has been noticed. However, the dynamic change and the heterogeneity of physical activity patterns among older people are little explored. PURPOSE This study aimed to identify the trajectory patterns of engaging in physical activity over time and its related factors. METHOD Nationally representative four-wave panel data from Taiwanese older adults, gathered between 1996 and 2007, were used (n = 4,018). The participants ranged in age from 50 to 96 years old. "Being physically active" was defined as performing physical activity in sports or exercises at least three times per week and lasting for at least 30 min each time. Group-based trajectory analysis was performed for analyzing the data. RESULTS Four trajectory patterns were identified: inactive (47.83%), decreasing (12.21%), increasing (23.36%), and active (16.60%). Older respondents and those with more education were more likely to be active. Those respondents having more depressive symptoms, having more physical functional limitations, and having jobs were less likely to be physically active in the decreasing, increasing, and active patterns. CONCLUSION There is heterogeneity among the trajectory patterns of physical activity across time in the older adults. Different strategies of physical activity promotion for the older people should be developed by the group characteristics.

Abstract
The purpose of this study was to examine happiness and social determinants across age cohorts in Taiwan. The data were obtained from the 2011 Taiwan Social Change Survey (aged 18 +, n = 2,199). The social determinants of happiness included socioeconomic status and social connection. Happiness was not different across the age groups. Receiving less family support, less formal support, more social trust and more control over life were significant for the younger group. Being married and having more social participation were significant for the middle-aged. Receiving less family support and having a higher economic status were significant for the older group.

Abstract
Indium segregation in a narrow InGaN single quantum well creates quantum dot (QD) like exciton localization centers. Cross-section transmission electron microscopy reveals varying shapes and lateral sizes in the range ∼1-5 nm of the QD-like features, while scanning near field optical microscopy demonstrates a highly inhomogeneous spatial distribution of optically active individual localization centers. Microphotoluminescence spectroscopy confirms the spectrally inhomogeneous distribution of localization centers, in which the exciton and the biexciton related emissions from single centers of varying geometry could be identified by means of excitation power dependencies. Interestingly, the biexciton binding energy (E(b)xx) was found to vary from center to center, between 3 to -22 meV, in correlation with the exciton emission energy. Negative binding energies are only justified by a three-dimensional quantum confinement, which confirms QD-like properties of the localization centers. The observed energy correlation is proposed to be understood as variations of the lateral extension of the confinement potential, which would yield smaller values of E(b)xx for reduced lateral extension and higher exciton emission energy. The proposed relation between lateral extension and E(b)xx is further supported by the exciton and the biexciton recombination lifetimes of a single QD, which suggest a lateral extension of merely ∼3 nm for a QD with strongly negative E(b)xx = -15.5 meV.

Cognitive function and associated factors among older people in Taiwan: age and sex differences. Arch Gerontol Geriatr 2014; 60:196-200. [PMID: 25456889 DOI: 10.1016/j.archger.2014.10.007] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2013] [Revised: 10/06/2014] [Accepted: 10/07/2014] [Indexed: 11/27/2022]
Abstract
PURPOSE The aim of this study was to examine cognitive function and the risk and the protective factors by age and sex among Taiwanese older people. METHODS The data were from a nation-representative panel of older people in Taiwan. The participants completing both the 2003 and 2007 waves were included for analysis in this study (n=3228). Descriptive analysis and generalized linear model were applied, and the samples were stratified by age groups and by sex. RESULTS The factors related to higher cognitive function at the intercept included being younger, male, higher education, and doing unpaid work. At the time slope, the age effect and physical function difficulties would reduce the cognitive function across time, while education and providing informational support would increase the cognitive function across time. There were age- and sex-differences in the factors related to cognitive function, particularly on the working status and social participation. CONCLUSION Different health promotion strategies to target these populations should be accordingly developed.

Teeth segmentation of dental periapical radiographs based on local singularity analysis. COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2014; 113:433-445. [PMID: 24252317 DOI: 10.1016/j.cmpb.2013.10.015] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2013] [Revised: 09/12/2013] [Accepted: 10/22/2013] [Indexed: 06/02/2023]
Abstract
Teeth segmentation for periapical raidographs is one of the most critical tasks for effective periapical lesion or periodontitis detection, as both types of anomalies usually occur around tooth boundaries and dental radiographs are often subject to noise, low contrast, and uneven illumination. In this paper, we propose an effective scheme to segment each tooth in periapical radiographs. The method consists of four stages: image enhancement using adaptive power law transformation, local singularity analysis using Hölder exponent, tooth recognition using Otsu's thresholding and connected component analysis, and tooth delineation using snake boundary tracking and morphological operations. Experimental results of 28 periapical radiographs containing 106 teeth in total and 75 useful for dental examination demonstrate that 105 teeth are successfully isolated and segmented, and the overall mean segmentation accuracy of all 75 useful teeth in terms of (TP, FP) is (0.8959, 0.0093) with standard deviation (0.0737, 0.0096), respectively.

Abstract
OBJECTIVE This study aimed to identify depressive symptoms among older Taiwanese adults and to explore the relationships between different comorbidities and depressive symptoms. METHODS The data used herein were obtained from four waves of a longitudinal nationwide survey of the older Taiwanese population conducted from 1996 to 2007. Two-level hierarchical linear modeling was employed to identify the trajectory of depressive symptoms predicted by comorbidities when controlling for time-constant and time-varying covariates. RESULTS The time slope had an increasing tendency of depressive symptoms across time. The older adults with cardiovascular disease (CVD), gastrointestinal disease, chronic respiratory disease (CRD), and the combination of two of these three diseases had a higher effect on the intercept of depressive symptoms. Only the older adults with CRD combined with CVD or with GI disease had a significant negative effect on the slope of depressive symptoms over time. Participants with higher emotional-social support had lower depressive symptoms, and the effect of this support could reduce depressive symptoms even more over time. CONCLUSIONS Different patterns of comorbidities might have an additive or modifying effect on depressive symptoms. Emotional social support had a buffering or moderating effect on the prevention of depressive symptoms. This information is helpful for further studies that would address the relationships between different comorbidities and depressive symptoms.

Improvement of hepatocyte recovery from rat liver subjected to 1-hour warm ischemic injury by using citrate phosphate dextrose added to euro-collins perfusion solution. Transplant Proc 2013; 45:1700-3.

Abstract
Warm ischemia (WI)-related injury interferes with recovery of primary hepatocyte after collagenase digestion of surgically resected or non-heart-beating donor livers as human cell sources. We speculated that digestion is impaired due to reduced microcirculation, caused by microembolism after WI. We sought to improve hepatocyte recovery after WI using a rat model. Anesthetized 9-week-old male Sprague-Dawley rats underwent a midline abdominal incision to insert a 22-gauge cannula into the portal vein. WI was initiated by ligating both the cannula and the hepatic artery. We compared Euro-Collins (EC) perfusion solution with 2 anticoagulants-heparin or citrate phosphate dextrose (CPD)-versus ethylene glycol tetraacetic acid (EGTA) combined with Ca(2+)- and Mg(2+)-free Hank's solution (CM-free Hank's solution). Use of CM-free Hank's solution yielded only 0.75 ± 0.15 × 10(8) and 0.82 ± 0.20 × 10(8) cells at 30 and 60 minutes WI respectively. However, CPD, but not heparin, added to the EC solution produced the best cell recovery (CPD: 2.15 ± 0.38 × 10(8); heparin: 1.63 ± 0.31 × 10(8)). During macroscopic observation, CPD added to EC solution also demonstrated best blood flushing. CPD added to EC solution achieved greater hepatocyte recovery than CM-free Hank's solution by restoring microcirculation during flushing of blood from liver tissue subjected to WI.

Abstract
AIM The aim of this study was to examine the effects of trajectories of physical function on later long-term care utilization based on longitudinal panel data of older adults. METHODS A representative longitudinal sample of older adults during the years 1993 to 2007 was used (n=1232). Trajectories of physical function from 1993 to 2007 were identified by group-based trajectory analysis, and then the relationships of the past trajectories with the use of nursing homes and care assistants, and the amount of utilization used in 2007 were examined. RESULTS Four groups of physical function difficulties trajectories were identified: none (38.8%), little (34.1%), late increasing (16.1%) and early increasing (11.0%). The early- and late-increasing difficulty groups were more likely to use and used more nursing homes and care assistants. In particular, a long-term disability is closely related to a larger probability of using nursing homes than using care assistants at home. The utilization of care assistants seems a priority choice at the early-increasing stage of disability. When the disability worsens and lasts a long time, a nursing home is then the next choice. CONCLUSION Past physical function trajectories relate to later long-term care utilization.

Abstract
PURPOSE The goals of this study were to examine the group-based trajectories of depressive symptoms over an extended period among the older people and to identify the risk factors by gender. METHODS The 18-year data used in this study came from a multiple-wave nationwide survey of older Taiwanese population. A group-based trajectory analysis method was used to identify the trajectories, and risk factors at baseline and previous depressive symptoms were used as predictors for the trajectories. RESULTS Six trajectories were identified within the total sample, and females were more likely to be in the increasing and declining trajectories than males. When the data were divided by gender, four trajectories for males and four trajectories for females were identified: low, medium, declining, and increasing. Higher-level trajectories of depressive symptoms were related to more chronic diseases, lower physical function, lower economic satisfaction, and previous depressive symptoms for both the older men and women. Less social support and social participation were related to higher depressive symptom trajectories, particularly for men. DISCUSSION Older females may experience more emotional fluctuation than male elderly, thus changes in psychosocial health for female elderly need to be considered by health professionals and families. Social support and social participation are protective against depressive symptoms for the higher-level trajectory groups, and older men, in particular, are more sensitive to these two social-health-related variables.

Abstract
AIM This study examined the relationships between health literacy, self-efficacy and preventive care utilization among older adults in Taiwan. METHODS The data were from a longitudinal survey, "Taiwan Longitudinal Study in Aging" in 2003 and 2007. A total of 3479 participants who completed both two waves were included for analysis. Health literacy first was constructed through education, cognitive function and disease knowledge through structural equation modeling (SEM); then, the associations of health literacy to later self-efficacy and preventive care were examined. RESULTS The model fit of SEM was good, indicating that the construct of health literacy was appropriate. Healthy literacy showed a moderate positive effect on self-efficacy and a small positive effect on preventive care utilization. CONCLUSIONS Health literacy increases self-efficacy and utilization of preventive care. Promoting people's health knowledge and health literacy is suggested.
