Physical, Mental, and Cognitive Function in a Convenience Sample of Centenarians in Australia

Multiple Roads to Success: A Latent Class Analysis on Successful Ageing Among Hong Kong Near-Centenarians and Centenarians (NCC)

Notwithstanding the oldest-old cohort being the fastest-growing population in most ageing societies, characterizing successful ageing in adults of advanced age, such as nonagenarians and centenarians, remains challenging. This study investigated the successful ageing subphenotypes using the data from Hong Kong Centenarian Study 2. Between April 2021 and September 2022, 146 family caregivers of community-dwelling older adults aged 95 or above were interviewed by phone. Latent class analysis identified three classes-Overall Frail (46.6%) with poor mobility, cognitive and functional health, Nonambulant (37.0%) but good functional health, and Robust (16.4%) with overall good health-from 11 indicators based on caregivers' reports. Although we found a low prevalence of fulfillment of all indicators of successful ageing, our findings will help care professionals appreciate the heterogeneity underlying partial successful ageing in this vulnerable cohort for segmented and targeted healthy longevity interventions.

Profiles of centenarians' functioning: linking functional and cognitive capacity with depressive symptoms

BACKGROUND

Despite most centenarians facing age-related declines in functional and cognitive capacities, the severity of these declines varies among individuals, as does the maintenance of good mental health (e.g., depressive symptoms) despite these declines. This study aims to examine this heterogeneity in centenarians from the Second Heidelberg Centenarian Study, which collected data from 112 centenarians living in Germany. In our study, we focus on a subsample of 73 centenarians who provided self-reports for our measures of interest (M age = 100.4, SD age = 0.55).

METHODS

We examined correlations between functional capacity (i.e., PADL, IADL), cognitive capacity (i.e., MMSE), and depressive symptoms (i.e., GDS), and the existence of different profiles using hierarchical clustering.

RESULTS

Higher functional capacity was related to higher cognitive capacity and to fewer depressive symptoms. Yet, higher cognitive capacity was associated with more depressive symptoms. Hierarchical clustering analysis elucidated this contradiction by identifying three profiles: low-capacity individuals (i.e., 24 individuals had low functional and cognitive capacities, with low depressive symptoms), high-capacity individuals (i.e., 33 individuals with high functional and cognitive capacities, with low depressive symptoms), and low-functional-high-cognitive-capacity individuals (i.e., 16 individuals showed low functional but high cognitive capacity, with high depressive symptoms). Our post-hoc analyses highlighted arthritis and pain as risk factors for functional dependence and depression.

CONCLUSIONS

Our findings emphasize the importance of identifying centenarian subgroups with specific resource- and risk profiles to better address their needs, and of treating pain to improve functional capacity and mental health in centenarians.

The relationship between depressive mood and subjective health in centenarians and near-centenarians: a cross-sectional study from Korean centenarian cohort

BACKGROUND

With the rapid increase in population longevity, more clinical attention is being paid to the overall health of long-lived people, especially centenarians. Subjective health, which is the perception of one's health status, predicts both mortality and declining physical function in older adults. The purpose of this study was to investigate the factors related to subjective health among centenarians and near-centenarians (ages ≥95) living in a rural area of South Korea.

METHODS

A total of 101 participants were enrolled from four different regions (Gurye, Gokseong, Sunchang, and Damyang), known as the Longevity Belt in Korea. Variables assessing physical and mental health, including the results of blood tests, were examined. Factors associated with good subjective health were identified with logistic regression analysis.

RESULTS

Fifty-six participants (59.6%) were subjectively healthy among the centenarians and near-centenarians. Logistic regression analysis revealed that depressive mood was the only factor associated with subjective health and was negatively correlated. The regression model explained 39% of the variance in subjective health.

CONCLUSIONS

These findings emphasize the importance of mental health at very advanced ages. Because depressive mood negatively correlates with subjective health, more attention is needed to prevent and manage mood symptoms of people of advanced ages, including centenarians.

Centenarians: who are they? A description of the total Swedish centenarian population in terms of living arrangements, health, and care utilization

BACKGROUND

The global centenarian population has doubled each decade and is expected to continue growing. However, information regarding how they live, their health status, and care needs is limited.

AIMS

This study aims to describe the total Swedish centenarian population in terms of health status, living arrangements, and socio-demographic characteristics.

METHODS

This nationwide register-based study included all Swedish people reaching age 100 between 2013 and 2018. We analyzed their socio-demographic characteristics, living arrangements, number of prescribed drugs, and health status. Moreover, their care transitions from age 100 and two years forward were described.

RESULTS

Of 5,882 centenarians (80.7% women), only 15.0% lived at home without formal care and 24.5% cohabited on their 100th birthday. Men (22.7%) were more likely than women (13.2%) to live at home without care. Approximately half of the centenarians lived in care homes, with fewer men (41.0%) than women (54.0%). Around 66.6% had a child living within the 50 km range. Most (76.5%) had an income below the median for Swedish older adults. Almost none were free from drugs, and polypharmacy was common (65.3%). Over half had at least one morbidity. Two years later, only 4.3% lived at home without care, and 63.9% died.

CONCLUSION

Sweden's centenarian population is highly dependent on home care and care homes. Among the ones still living at home, the vast majority live alone and have low incomes. Strategies to manage health and social care demands of this growing population group in the coming decade are important.

Association among Terminally Differentiated T Cells, Frailty, and Dependency in a Group of Cuban Centenarians

INTRODUCTION

Centenarians are considered a model of successful aging. Cuba exhibits one of the oldest populations in Latin America with more than two thousand centenarians.

METHODS

This study aimed to evaluate the immune phenotype of forty-three Cuban centenarians, their clinical characteristics such as comorbidities, frailty, body mass index, and some hemochemical parameters.

RESULTS

Centenarians had normal body mass indexes, relatively good health status, and 21.95% of them had no comorbidities; 53.6% were classified as frail, and 7% were classified as robust. In addition, 17% of centenarians were independent, and 41.46% were moderately dependent. The seroprevalence against cytomegalovirus was 100%. Concerning pro-inflammatory markers, the majority of them had very low cytokine levels and serum C-reactive protein around the normal limit. We also found the predominance of memory subsets over naive compartments in CD4+ and CD8+ T cells. Terminally differentiated CD8+CD28- T cells were higher in frail centenarians than in pre-frail, while CD8+CD57+ and CD8+EMRA T cells were higher in moderately and severely dependent individuals than in independent individuals. Severely dependent centenarians had a lower CD4+/CD8+ ratio.

CONCLUSION

This study describes for the first time the predominance of memory subsets over naive compartments in CD4+ and CD8+ T cells, as well as its relation to frailty and/or dependency in a group of Cuban centenarians. Further studies are needed to continue understanding the natural biological aging mechanism and the relationship between terminally differentiated lymphocytes and inflammaging in the context of extreme longevity.

Association between changes in depressive symptoms and hip fracture among middle-aged and older Chinese individuals: a prospective cohort study

Background

Although studies have shown that depressive symptoms are associated with an increased risk of hip fracture (HF). Depressive symptoms are dynamic, and it is unclear whether HF risk persists if depressive symptoms remit. This study aims to examine the associations between changes in depressive symptoms and HF risk.

Methods

Data were from the China Health and Retirement Longitudinal Study from 2011 to 2018. Depressive symptoms were measured using the 10-item version of the Center for Epidemiological Studied Depression scale (cutoff ≥ 10). Changes in depressive symptoms were classified into four groups by two successive surveys (stable low/no, recent-onset, recently remitted, and stable high depressive symptoms). Multivariable logistic regressions were performed to assess whether changes in depressive symptoms were associated with HF incidents reported through 2018, adjusting for age, sex, educational level, marital status and other potential confounding factors.

Results

In total, 8574 participants were included, 265 (3.1%) of whom had reported HF incidents in the subsequent 5-year period. Participants with recent-onset (OR = 1.97, 95% CI = 1.40–2.77) or stable high (OR = 2.15, 95% CI = 1.53–3.02) symptoms had a higher risk of HF than those with stable low/no depressive symptoms, whereas those with improved depressive symptoms (OR = 1.27, 95% CI = 0.89–1.82) had no elevation in HF risk.

Conclusion

Stable high and recent-onset depressive symptoms were associated with increased HF risk, and no elevated HF risk was observed if symptoms remitted, suggesting that strategies to reduce depressive symptoms may be beneficial for HF prevention.

Oral health and functional capacity of centenarians

The number of very old individuals, namely centenarians, is growing fast. In dentistry, the increasing number of older adults retaining natural teeth present new challenges for preventive and restorative dental care. However, there is a considerable lack of knowledge on the oral health status and needs in this exceptional age group. The aim of this population-based study was to identify the prevalence of oral diseases, therapeutic needs and functional capacity (evaluating centenarians' autonomy and their capabilities regarding treatment and oral hygiene) in centenarians. Subjects born before 1920 were recruited from population registries in South-Western Germany, providing information on dental health experiences, oral health behaviors and undergoing dental examination. 55 centenarians participated in the study (mean age ± SD = 101.2 ± 1.6, 83.6% females). Results were compared to epidemiological data on adults aged 75-100 years examined in the Fifth German Oral Health Study. Adherence to recommended dental behaviors and dental check-ups was lower in the centenarian population. Moreover, with the exception of a lower Root Caries Index, centenarians showed a higher caries experience, and presented with a mean DMFT of 25.2 ± 3.9, a DMFS of 111.0 ± 21.8, a root caries prevalence of 34.5% and a Restorative Index of 54.0%. Centenarians' functional capacity was also considerably lower. Non-existent or greatly reduced treatment capabilities and oral hygiene capabilities were registered in 63.7% and 43.6% of cases, respectively. Centenarians with a lower educational level (p = 0.018), in a care facility (p = 0.045) or in need of nursing care (p = 0.001) were more likely to have a low functional capacity. 98.2% of centenarians received help in their daily activities but only 12.7% in their oral hygiene. In conclusion, although most still have natural teeth, a decline of oral health can be perceived. As compliance with recommended behaviors is limited and most centenarians can no longer undergo dental treatment, the lack of assistance in daily oral health care is problematic.

Serum albumin and activities of daily living in Chinese centenarians: a cross-sectional study

BACKGROUND

Objective deterioration in activities of daily living (ADLs) exists among older population, and particularly worsens with age. Considering the criterion standard of positive aging and longevity, little information focusing on centenarians is available. This study set out to explore the relationship between serum albumin and ADLs among centenarians in long-lived areas.

METHODS

This population-based cross-sectional study investigated a full sample of Chinese centenarians in Hainan, the longest-lived area of China (n = 1002). We assessed serum albumin levels and basic and instrumental activities of daily living (BADLs and IADLs).

RESULTS

Of 1002 participants included in the analysis, 287 (28.64%) had BADL disabilities and 648 (64.67%) had IADL disabilities. The median level of serum albumin was 38.5 g/L (interquartile range, 36.2-41.3). The multivariable analyses controlling for socio-demographic characteristics, lifestyle, morbidities, and other influential factors showed that albumin level was associated with the total score of BADL (standard β = 0.335, P < 0.001) and IADL (standard β = 0.206, P < 0.001). With the increasing of albumin level, the risk of ADLs disability decreased (BADL: odds ratios [OR] = 0.835, 95% Confidence interval [CI]: 0.797-0.876; IADL: OR = 0.863, 95%CI: 0.824-0.905). In the stratified analyses, similar results were found in both sex, but were more prominent in women.

CONCLUSIONS

Higher levels of serum albumin was a protective factor for the decline of ADLs in centenarians. This association can be observed in both genders and is more pronounced in women.

Analyzing functional status and its correlates in Chinese centenarians: A cross-sectional study

Factors affecting independence in basic and instrumental activities of daily living have been established in older adults, but not centenarians. The purpose of this study was to examine the state and factors affecting activities of daily living independence in centenarians who resided in Guangxi Province, China. A cross-sectional design was used. Activities of daily living, physical activity, mobility, and physical performance were measured by the Population Study of ChINese Elderly study instruments, and demographics and cognition were assessed. Of the 228 participants, 57% were independent in basic activities of daily living and 5.7% in instrumental activities of daily living. Stepwise regression showed physical activity, cognition, calf circumference, and self-reported health were associated with basic activities of daily living. Physical activity, mobility, cognition, and physical performance were correlated with instrumental activities of daily living. In conclusion, the Chinese centenarians showed impaired instrumental activities of daily living but mostly maintained basic functioning. Physical activity and cognition were associated with activities of daily living independence.

The prevalence and predictors of anxiety and depression in near-centenarians and centenarians: a systematic review

BACKGROUND

Current research on the psychological health of near-centenarians (95-99 years old) and centenarians remains limited. Existing studies have mainly characterized their physical, cognitive, and social health. Results on the anxiety and depression of near-centenarians and centenarians (more than 95 years old) have been mixed with some studies, finding higher rates of anxiety and depression among those older than 95 years and others reporting no difference in rates compared with younger age groups. This study aims to synthesize the existing literature on the prevalence and predictors of anxiety and depression in near-centenarians and centenarians.

METHOD

A systematic review was conducted using Ovid Medline, Embase, PsycINFO, CINAHL, SCOPUS, and the Cochrane database. Common and conflicting findings among the literature were examined.

RESULTS

Thirty-eight studies met the inclusion criteria. Six studies examined the prevalence and predictors of anxiety, and 37 studies investigated the prevalence and predictors of depression. Five studies examined both anxiety and depression in the same sample. Prevalence data on anxiety and depression varied significantly, as did comparisons with rates in younger populations. Findings on predictors of anxiety and depression were contradictory.

CONCLUSION

There is a large degree of heterogeneity among studies of centenarians' psychological status. Findings conflict on the prevalence and predictors of anxiety and depression and rates compared with younger age groups. Variation in findings may result from the different inclusion criteria, sampling methods, and measurement tools. Better harmonization of centenarian study methodologies may improve consistency of findings to aid in developing clinical interventions.

The psychological health of 207 near-centenarians (95-99) and centenarians from the Sydney Centenarian Study

OBJECTIVE

While near-centenarians (95-99) and centenarians are the fastest growing sectors of the population in many countries, few studies have investigated their psychological health. We aimed to compare levels of psychological distress and life satisfaction in individuals aged 95 or above (95+) with younger age groups and identify the factors associated with psychological distress and life satisfaction in near-centenarians and centenarians.

METHODS

We assessed the physical, cognitive, social and psychological health of 207 participants aged 95+ in the Sydney Centenarian Study. Psychological distress and life satisfaction were rated on the Kessler Psychological Distress Scale (K10) and Satisfaction with Life Scale, respectively. Cross-sectional univariate comparisons were performed with participants aged 70-90 years from the Sydney Memory and Ageing Study. Factors associated with psychological distress and life satisfaction among Sydney Centenarian Study participants were examined using multiple regression analyses.

RESULTS

In Sydney Centenarian Study and Memory and Ageing Study, mean K10 scores were 15.3 (±5.9) and 13.4 (±3.6), and clinical levels of psychological distress (K10 ⩾ 20) were 19% and 7%, respectively. Sydney Centenarian Study participants demonstrated significantly higher levels and rates of psychological distress (t = 3.869, p < 0.001; χ² = 27.331, p < 0.001). In Sydney Centenarian Study, more psychotropic medications and having fewer relatives and friends were associated with higher psychological distress. Sydney Centenarian Study participants reported significantly higher levels of life satisfaction than Memory and Ageing Study participants, mean scores 6.0 (±1.5) and 5.6 (±1.3); t = 5.835, p < 0.001. Lower Mini-Mental State Examination scores and having fewer relatives and friends were associated with lower life satisfaction in Sydney Centenarian Study.

CONCLUSION

Despite showing higher levels of psychological distress in the prior 4 weeks than younger age groups, near-centenarians and centenarians remained highly satisfied with their overall lives. The identification of risk and protective factors for psychological distress and life satisfaction provides opportunities for interventions to maintain good psychological health in this vulnerable population.

Aging without Dementia is Achievable: Current Evidence from Epidemiological Research

Both the incidence and the prevalence of dementia increase exponentially with increasing age. This raises the question of whether dementia is an inevitable consequence of aging or whether aging without dementia is achievable. In this review article, we sought to summarize the current evidence from epidemiological and neuropathological studies that investigated this topic. Epidemiological studies have shown that dementia could be avoided even at extreme old ages (e.g., centenarians or supercentenarians). Furthermore, clinico-neuropathological studies found that nearly half of centenarians with dementia did not have sufficient brain pathology to explain their cognitive symptoms, while intermediate-to-high Alzheimer pathology was present in around one-third of very old people without dementia or cognitive impairment. This suggests that certain compensatory mechanisms (e.g., cognitive reserve or resilience) may play a role in helping people in extreme old ages escape dementia syndrome. Finally, evidence has been accumulating in recent years indicating that the incidence of dementia has declined in Europe and North America, which supports the view that the risk of dementia in late life is modifiable. Evidence has emerged that intervention strategies that promote general health, maintain vascular health, and increase cognitive reserve are likely to help preserve cognitive function till late life, thus achieving the goal of aging without dementia.

‘Just another day’: the lived experience of being a hundred years old for ten New Zealanders

The aim of this study was to gain an understanding of the experiences of extended longevity as perceived by centenarians. Centenarians (people over 100 years of age) are the fastest growing group of the ageing population in developed countries. Ten centenarians aged between 100 and 106 years, living in the Lower North Island of New Zealand, participated in the study. The biographical narrative interpretive method of inquiry guided data collection through face-to-face interviews, and thematic analysis was subsequently undertaken. Four themes were identified: (a) ‘becoming a centenarian: ‘Just another day’; (b) ‘growing up in a privileged environment’ that revealed four sub-themes: ‘having freedom and choice’, ‘being loved and nurtured’, ‘living healthy lifestyles’ and having ‘good education prospects’; (c) ‘unique opportunities in adult life’; and (d) ‘positive ageing and celebration of longevity’. The centenarians spoke nonchalantly about their experience of turning 100 and positive personalities were prominent features of the participants, who all expressed a sense of acceptance and satisfaction with life and contentment with living in the present, a feature throughout their lives that was ongoing and at an intergenerational level. This study has provided further insights into the existing literature on longevity and through the narratives of the centenarians has demonstrated the value of Erikson's psycho-social stages of development and Tornstam's theory of gerotranscendence when considering positive ageing.

Prevalence of functional dependence in Chinese centenarians and its relationship with serum vitamin D status

Background

Functional dependence (FD) and vitamin D deficiency are common conditions in older adults. However, little is known about the relationship between FD and serum vitamin D status in centenarians. The current study was designed to evaluate the prevalence of FD and examine its relationship with serum vitamin D status among centenarians in China.

Subjects and methods

A cross-sectional study of a large sample of Chinese centenarians including 180 men and 822 women was conducted from June 2014 to December 2016. Home interviews, physical examinations, and blood analyses were performed in 958 centenarians following standard procedures. FD was evaluated using the Barthel index of activities of daily living (ADL). Serum 25-hydroxyvitamin D (25OHD) concentrations were measured as a marker of vitamin D status.

Results

The prevalence of centenarians with FD was 71.2%. Vitamin D deficiency, lack of tea consumption, lack of outdoor activities, visual impairment, and fracture were predictors of FD. Centenarians in the lowest quartile of serum 25OHD concentration had an approximately threefold greater likelihood of FD than those in the highest quartile in multiple logistic regression models (OR =2.88; 95% CI 1.75–4.73; P<0.001). The multivariable OR with a 1 ng/mL decrease in serum 25OHD concentration was 1.06 (95% CI 1.04–1.08; P<0.001) for FD.

Conclusion

Serum 25OHD levels have important associations with FD in Chinese centenarians. Future research could focus on the value of intervening in the case of low serum 25OHD levels through vitamin D supplementation and improving ADL in the older population.

Nutrition and Inflammation: Are Centenarians Similar to Individuals on Calorie-Restricted Diets?

Individuals capable of reaching the extreme limit of human life such as centenarians are characterized by an exceptionally healthy phenotype—that is, a low number of diseases, low blood pressure, optimal metabolic and endocrine parameters, and increased diversity in the gut microbiota—and they are epigenetically younger than their chronological age. We present data suggesting that such a remarkable phenotype is largely similar to that found in adults following a calorie-restricted diet. Interviews with centenarians and historical data on the nutritional and lifestyle habits of Italians during the twentieth century suggest that as children and into adulthood, centenarians lived in an environment that was nonobesogenic, but at the same time the environment did not produce malnutrition. Centenarians appear to be creatures of habit, and we argue that their habit of eating meals at the same time each day favored the maintenance of circadian rhythms, including their sleep cycle. Finally, we argue that centenarians’ chronic inflammatory status, which we dubbed inflammaging, is peculiar, likely adaptive, and less detrimental than in younger people.

The assessment of anxiety in aged care residents: a systematic review of the psychometric properties of commonly used measures

ABSTRACTBackground:Assessing anxiety among residential aged care facility (RACF) residents is challenging, and it cannot be assumed that valid and reliable measures used within the community are also appropriate for this setting. This review systematically examined the literature to identify which anxiety measures were most commonly used with older adults in RACFs, and determine whether psychometric data support their use within this population.

METHODS

Using the PRISMA guidelines, five electronic databases were searched using key terms and subject headings. The search was limited to literature published in English. Eligible studies utilized an anxiety measure to assess anxiety symptoms among RACF residents. Based on the findings of this search, a critical review of the research into the reliability, validity, and administrative and respondent burden of the most commonly used measures (i.e. used in four or more studies) was conducted.

RESULTS

In total, 1,771 articles were identified, with 50 studies included in this review. Overall, 22 measures were used, with the majority of studies utilizing a clinician-administered or self-report measure. The RAID, HADS, STAI, and GAI were the most commonly used measures. While overall there is a lack of research and consensus into the psychometric properties of these measures within RACFs, strongest evidence of reliability and validity was found for the GAI.

CONCLUSION

Commonly used measures of anxiety within aged care populations are not well validated for this complex subsample of older adults. Strengths and weaknesses of each measure with regards to their usefulness in aged care settings are discussed, with future research areas highlighted.

Centenarians' End-of-Life Thoughts and Plans: Is Their Social Network on the Same Page?

OBJECTIVES

To explore how centenarians think about and plan for the end of life (EOL) and to what extent their primary contacts (proxy informants) are aware of these thoughts.

DESIGN

Population-based study with semistructured in-person interviews.

SETTING

Defined geographical region approximately 60 km around Heidelberg, Germany.

PARTICIPANTS

Subsample drawn from the larger study of centenarians (N = 78) with data on centenarians' EOL thoughts from the centenarian and the proxy informant.

MEASUREMENTS

Centenarians reported on their thoughts about the EOL, perception of the EOL as threatening, longing for death, engagement in any EOL planning, and type of EOL plan (will, living will, healthcare surrogate) in place. Proxy respondents answered the same set of questions based on what they thought the centenarians' perspective was.

RESULTS

In nearly half of cases, proxies misjudged whether the centenarian thought about EOL. Although only few centenarians perceived the EOL as threatening, and approximately one-quarter reported longing for death, proxies overestimated centenarians' reports on the former and underestimated the latter. Proxies reported more centenarian EOL planning than centenarians themselves.

CONCLUSION

Even though enrolled proxies were mostly persons very close to the centenarian, many of them did not seem to be well informed about the centenarians' thoughts and plans regarding the EOL, suggesting a lack of communication between centenarians and social network members in this respect. Healthcare professionals should be aware that, even for very old adults approaching the end of their lives, discussions about EOL and EOL planning may need to be actively encouraged and supported.

Long-term Care Status in Centenarians and Younger Cohorts of Oldest Old in the Last 6 Years of Life: Trajectories and Potential Mechanisms

OBJECTIVES

A large proportion of the oldest old and centenarians live in long-term care facilities. Although there may be distinct care patterns in centenarians compared with other cohorts of oldest old, the exact development concerning prevalence, length of stay, and factors that are associated with long-term care status in the last years before death is unknown.

DESIGN

Longitudinal analyses of health insurance data across 6 years before death.

SETTING AND PARTICIPANTS

In all, 1398 institutionalized and noninstitutionalized oldest old [deceased at 80-89 (octogenarians), 90-99 (nonagenarians), or over 100 years of age (centenarians)] from Germany were included. Long-term care status and transition from home care into long-term care over 6 years (34,740 person-quarters).

MEASUREMENTS

Dementia, musculoskeletal diseases, multimorbidity, hospital admission, gender, and age at death were derived from administrative data and analyzed using binary generalized estimating equations.

RESULTS

Although the initial level of long-term care (6 years before death) was higher among centenarians (65.1% vs 53.6% in nonagenarians; 36.2% in octogenarians), the rate of increase was stronger in the younger cohorts. Distinguishing between long-term care escapers, delayers, and survivors, the proportion of those who escaped, delayed, or survived the entire 6 years of observation in long-term care was 33.4%/40.4%/26.2% in centenarians, 45.0%/45.1%/9.9% in nonagenarians, and 62.7%/33.7%/3.6% in octogenarians. Age, hospital admissions, and dementia were positively associated with being in long-term care, whereas musculoskeletal disorders were negatively associated with long-term care. The association with dementia was significantly weaker in centenarians.

CONCLUSIONS

For centenarians, although they are more often in long-term care, the transition rate to long-term care progressed more slowly than the rates of the younger comparison cohorts of oldest old. The high proportion of long stays of centenarians in long-term care facilities require different concepts of long-term care.

Optimism and Well-Being Among Institutionalized Older Adults

Abstract. Institutionalization is often related to the psychologically negative outcomes of old age. Optimism could alleviate suffering, but little is known about its role in institutionalized settings. We sought to explore optimism correlates and to determine whether it predicts emotional well-being variables, after controlling for potential covariates, by assessing 66 institutionalized elderlies. Optimism was low and associated with failure to do physical exercise, urinary incontinence, increased anxiety, depressive symptoms and feelings of loneliness, and reduced satisfaction with life and positive affect. Optimism predicted emotional well-being, albeit not over and above some covariates. Given the low optimism levels and the correlates, we suggest that intrapersonal resources could be intervention targets. It is our hope that our findings will inspire research to analyze interventions promoting optimism-beneficial combinations of well-being among institutionalized older adults.

Health and Disease at Age 100

BACKGROUND

Centenarian studies from around the world have shown that reaching age 100 typically involves substantial health issues. The present study adds to the existing knowledge from other countries by describing health conditions in German centenarians.

METHODS

A total of 112 centenarians or their primary contacts provided information on acute and chronic health conditions and pain in the context of the Second Heidelberg Centenarian Study (mean age = 100.45 years, standard deviation [SD] = 0.47, 89% females).

RESULTS

Participants showed high comorbidity, with an average of five illnesses (mean = 5.3; SD = 2.20). Health conditions with highest prevalence were sensory (vision, hearing; 94%), mobility (72%) and musculoskeletal conditions (60%). Cardiovascular conditions (57%) and urinary system ailments (55%) were also common. Pain was experienced often by 30% of the participants. Of those reporting any pain, 36% indicated pain exceeding bearable levels.

CONCLUSION

German centenarians experienced a substantial number of ill nesses, dominated by sensory and mobility conditions. Cardiovascular diseases were the only potentially lethal illnesses with high prevalence. Evidence of unaddressed pain seems alarming, requiring future research. Emerging health profiles indicate that even in very advanced age, quality of life may be improved by enhanced diagnostics and optimal disease management. Mobility limitations may be addressed with preventive efforts.

Sociodemographic and Clinical Characteristics of Centenarians in Mexico City

Background

There is little evidence about the demography and health status of adults aged 100 years and over in Latin America and there are no studies in Mexico.

Objectives

To describe the demographic characteristics and health status of centenarians residing in Mexico City.

Methods

This is a cross-sectional study using a population base of 393 community-dwelling centenarians in Mexico City. A comprehensive geriatric assessment was performed, including demographic information and health status.

Results

The mean age of centenarians was 101.82 ± 2.02 years, of whom 44 (9.1%) were semisupercentenarians (105–109 years old) and 5 (0.2%) were supercentenarians (≥110 years old). The female/male ratio was 3.2 : 1. Twelve (4.5%) reside in nursing homes. Women versus men have unfavorable conditions given their criteria: being without a partner, dependence in 1 or more basic activities, dependence in 1 or more instrumental activities, hypertension, cancer, and Parkinson's disease. Nevertheless, as compared to other populations, Mexican centenarians report having good self-perception of health (78.9%), polypharmacy (17.8%), low rate of pain (11.4%), diabetes (4.8%), and dyslipidemia (1.8%).

Conclusions

This is the first study in Latin America that describes the social and clinical characteristics of centenarians in Mexico City. This population has a high percentage of malnutrition and osteoarthrosis, a high self-perception of health, low frequency of diabetes, dyslipidemia, cardiovascular disease, and a high frequency of “escapers” (24%).

Cognitive status in the oldest old and centenarians: a condition crucial for quality of life methodologically difficult to assess

Human life expectancy and the number of the oldest old are rapidly increasing worldwide. Advanced age is the main risk factor for dementia, representing one of the major causes of disability/dependency among older people with a strong impact on their families/caregivers. Centenarians have reached the extreme limits of human life escaping or delaying the major age-related diseases. Thus, these extraordinary individuals embody the best model to answer the crucial question if cognitive decline and dementia are progressive and unavoidable occurrences of increasing age. Despite a growing amount of data underlines the importance of cognitive function for quality of life and survival in old age, studies on centenarians have paid more attention to their physical condition rather than the assessment of their actual cognitive abilities. Accordingly, this work aims to summarize available data on the prevalence of dementia in centenarians and to critically address topics which can have a relevant impact on the cognitive assessment/status of the oldest old: (i) lack of standardized tools for cognitive assessment; (ii) criteria and threshold to establish the presence of dementia; (iii) influence of birth cohort and education; (iv) role of depression or positive attitude towards life; (v) gender differences.

Health profile of centenarians in Portugal: a census-based approach

BACKGROUND

The number of centenarians is rapidly increasing in Europe. In Portugal, it has almost tripled over the last 10 years and constitutes one of the fastest-growing segments of the population. This paper aims to describe the health and sociodemographic characteristics of Portuguese centenarians as given in the 2011 census and to identify sex differences.

METHODS

All persons living in Portugal mainland and Madeira and Azores islands aged 100 years old at the time of the 2011 census (N = 1,526) were considered. Measures include sociodemographic characteristics and perceived difficulties in six functional domains of basic actions (seeing, hearing, walking, cognition, self-care, and communication) as assessed by the Portuguese census official questionnaires.

RESULTS

Most centenarians are women (82.1 %), widowed (82 %), never attended school (51 %), and live in private households (71 %). The majority show major constraints in seeing (67.4 %), hearing (72.3 %), and particularly in their mobility (83.7 % cannot/have great difficulties in walking/climbing stairs and 80.7 % in bathing/dressing). In general, a better outcome was found for reported memory/concentration and understanding, with 39.1 % and 42.5 % presenting no or mild difficulty, respectively. Top-level functioning (no/mild difficulties in all dimensions concurrently) was observed in a minority of cases (5.96 %). Women outnumber men by a ratio of 4.6, and statistically significant differences were found between men and women for all health-related variables, with women presenting a higher percentage of difficulties.

CONCLUSION

Portuguese centenarians experience great difficulties in sensory domains and basic daily living activities, and to a lesser extent in cognition and communication. The obtained profile, though self-reported, is important in considering the potential of social and family participation of this population regardless of their functional and sensory limitations. Based on the observed differences between men and women, gender-specific and gender-sensitive interventions are recommended in order to acknowledge women's worse overall condition.

Physical, cognitive, social and mental health in near-centenarians and centenarians living in New York City: findings from the Fordham Centenarian Study

BACKGROUND

Despite their strong increase, the population of the very old, including near-centenarians and centenarians, represent an unstudied and underserved population. Available studies mostly concentrate on predictors of exceptional longevity, but rarely extend their focus to other areas of functioning. Also, little is known about what contributes to experiencing a quality life in very old age. The present population-based study aims at providing a comprehensive picture of key domain of functioning, including physical, cognitive, social and mental function in very old individuals and to determine predictors of mental health indicators.

METHODS

A total of 119 individuals aged 95 to 107 living in private dwellings and residential care facilities were recruited based on the New York City Voters Registry. Participants answered questions regarding their health and activities of daily living. Their cognitive functioning was determined using the Mini-Mental State Examination and the Global Deterioration Scale. Social resources were measured with number of children and the Lubben Scale. Mental health was assessed with the Geriatric Depression Scale and the Satisfaction with Life Scale.

RESULTS

An unexpectedly large proportion of the sample lived in the community. On average, cognitive functioning was high. Although five diseases were reported on average, participants reported good health. Functional status was reduced. Most participants had at least one person for communication/social support. On average, depression was below cut-off, and most participants reported high life satisfaction. Regression analyses indicated that individual differences in depression were associated with subjective health, IADL and relatives support. For life satisfaction, subjective health, ADL and number of children were most important. Demographic characteristics, number of illnesses or cognitive status were not significant.

CONCLUSIONS

Despite reduced levels of physical functioning and social resources, very old participants were in good mental health suggesting high resilience and ability to adapt to age-associated challenges. That a large proportion of them lived in the community further highlights their desire for leading an autonomous life, which may have been facilitated by New York service culture. More research is necessary to provide guidance for the development of well-suited services for this very old population.

Predictors of anxiety in centenarians: health, economic factors, and loneliness

BACKGROUND

Centenarians' psychological well-being is presently of great interest in psychogeriatric research but little is known about factors that specifically account for the presence of clinically relevant anxiety symptoms in this age group. This study examined the presence of anxiety and its predictors in a sample of centenarians and aims to contribute to a better understanding of anxiety determinants in extreme old age.

METHODS

We examined how socio-demographic, health, functional, and social factors contribute to the presence of clinically significant anxiety symptoms in centenarians recruited from two Portuguese centenarian studies. The Geriatric Anxiety Inventory - Short Form (GAI-SF) was used to assess anxiety symptoms.

RESULTS

A total of 97 centenarians (mean age 101.1 years; SD = 1.5 years; range = 100-108) with no/minor cognitive impairment were included. Clinically significant anxiety symptoms (GAI-SF ≥3) were present in 45.4% (n = 44) of the sample. Main predictive factors included worse health perception, higher number of medical conditions, financial concerns related to medical expenses (income inadequacy) and loneliness.

CONCLUSIONS

Results suggest that along with health status (subjective and objective), income inadequacy related to medical expenses and feeling lonely may predispose centenarians to clinically significant anxiety and be important to their overall well-being. Further research is needed on the repercussions of clinical anxiety in centenarians' quality of life and on co-morbid conditions (e.g. depression) at such advanced ages.

Suicide in centenarians: the international landscape

BACKGROUND

The elderly population size is growing worldwide due increased life expectancy and decreased mortality in the elderly. This has lead to an increase in the number of centenarians, and their numbers are predicted to increase further. Little is known about suicide rates in centenarians.

METHODS

Data on the number of suicides (ICD-10 codes, X60-84) in entenarians of both gender for as many years as possible from 2000 were ascertained from three sources: colleagues, national statisics office websites and e-mail contact with the national statistics offices of as many countries as possible. The number of centernarians for the corresponding years was estimated for each country using data provided by the United Nations website.

RESULTS

Data were available from 17 countries. The suicide rate was 57 (95% confidence interval 45-69) per 100, 000 person years in men and 6.8 (95% confidence interval 5.1-8.5) per 100,000 person years in women.

CONCLUSIONS

Suicide rates were sufficiently large amongst centenarians for there to constitute a public health concern given the anticipated rise in the centenarian population and the paucity of data on risk and protective factors for suicide in this age group.

Determining the predictors of change in quality of life self-ratings and carer-ratings for community-dwelling people with Alzheimer disease

The aim of this study was to determine the factors that mediate changes in Health Related Quality of Life (HRQoL) ratings by community-dwelling people with Alzheimer disease (AD) and carers over a period of 18 months. We completed an 18-month longitudinal study of 80 community-dwelling older adults diagnosed with probable AD of mild or moderate severity (NINCDS-ADRD criteria) and their family carers. The primary outcome of interest was the 18-month change in HRQoL ratings as measured with the Quality of Life-AD (QoL-AD) (by carer and by self). Explanatory variables included demographics, lifestyle, cognition, awareness, psychopathology, burden-of-care, use of medication, and functionality in daily life. We found a significant decline (8.7%, P=0.003) in QoL-AD carer-ratings, but not in self-ratings. The final parsimonious model of predictors of changes in QoL-AD self-ratings explained 22.6% of the variance; only changes on Hospital Anxiety and Depression Scale Anxiety retained significance. The final model of predictors of changes in carer-ratings explained 55.0% of the variance: that is, changes on Informant Questionnaire on Cognitive Decline in the Elderly, changes on Hospital Anxiety and Depression Scale Depression, practicing hobbies at 18 months, and number of visit(s) or admission(s) to hospital. HRQoL self-ratings and carer-ratings of community-dwelling people with AD do not decline at same rate over 18 months and changes are associated with different factors. Interventions designed to optimize quality of life of people with AD should consider carefully whose HRQoL ratings they wish to change.

The contribution of personality to longevity: findings from the Australian Centenarian Study

OBJECTIVES

To examine whether centenarians have a unique set of personality traits, which may in part explain their longevity.

METHODS

79 Australian centenarians completed the NEO Five Factory Inventory (NEO-FFI), Connor-Davidson Resilience Scale (CD-RISC) and Life Orientation Test Revised (LOT-R) to assess different dimensions of their personalities. Centenarians were asked to answer items of the NEO-FFI, CD-RISC and LOT-R based on current views, and were then asked to recall in the presence of an informant (e.g. carers, offspring) on past personality (i.e. at mid-adult-life). Both sets of answers were recorded and analysed.

RESULTS

Centenarians were currently low in Openness and Extraversion and high in Neuroticism, but were low in Openness and high in Neuroticism, Conscientiousness and Extraversion when reflecting on past traits. Currently, centenarians in high care facilities reported higher levels of Neuroticism, as did centenarians who did not socialize. Cognitively intact centenarians reported higher levels of Agreeableness; and males reported lower Neuroticism compared to females when reflecting on past experiences.

DISCUSSION

Centenarians were characterized by several personality traits, which facilitated positive health behaviors and thus contributed to their longevity. It is possible that personality may not be static across the lifespan, but instead, reflect advancing age, psychosocial factors and changes in life circumstances.

The relationship between functional status and judgment/problem solving among individuals with dementia

OBJECTIVE

To determine the relationship between functional status (independent activities of daily living) and judgment/problem solving and the extent to which select demographic characteristics such as dementia subtype and cognitive measures may moderate that relationship in older adult individuals with dementia.

METHODS

The National Alzheimer's Coordinating Center Universal Data Set was accessed for a study sample of 3,855 individuals diagnosed with dementia. Primary variables included functional status, judgment/problem solving, and cognition.

RESULTS

Functional status was related to judgment/problem solving (r = 0.66; p < 0.0005). Functional status and cognition jointly predicted 56% of the variance in judgment/problem solving (R(2) = 0.56, p < 0.0005). As cognition decreases, the prediction of poorer judgment/problem solving by functional status became stronger.

CONCLUSIONS

Among individuals with a diagnosis of dementia, declining functional status as well as declining cognition should raise concerns about judgment/problem solving.

Validation of prescribing appropriateness criteria for older Australians using the RAND/UCLA appropriateness method

OBJECTIVE

To further develop and validate previously published national prescribing appropriateness criteria to assist in identifying drug-related problems (DRPs) for commonly occurring medications and medical conditions in older (≥65 years old) Australians.

DESIGN

RAND/UCLA appropriateness method.

PARTICIPANTS

A panel of medication management experts were identified consisting of geriatricians/pharmacologists, clinical pharmacists and disease management advisors to organisations that produce Australian evidence-based therapeutic publications. This resulted in a round-one panel of 15 members, and a round-two panel of 12 members.

MAIN OUTCOME MEASURE

Agreement on all criteria.

RESULTS

Forty-eight prescribing criteria were rated. In the first rating round via email, there was disagreement regarding 17 of the criteria according to median panel ratings. During a face-to-face second round meeting, discussion resulted in retention of 25 criteria after amendments, agreement for 14 criteria with no changes required and deletion of 9 criteria. Two new criteria were added, resulting in a final validated list of 41 prescribing appropriateness criteria. Agreement after round two was reached for all 41 criteria, measured by median panel ratings and the amount of dispersion of panel ratings, based on the interpercentile range.

CONCLUSIONS

A set of 41 Australian prescribing appropriateness criteria were validated by an expert panel. Use of these criteria, together with clinical judgement and other medication review processes such as patient interview, is intended to assist in improving patient care by efficiently detecting potential DRPs related to commonly occurring medicines and medical conditions in older Australians. These criteria may also contribute to the medication management education of healthcare professionals.

Quality of life in Alzheimer's disease: different factors associated with complementary ratings by patients and family carers

BACKGROUND

Quality of life (QoL) in dementia is a complex construct and factors that predict QoL ratings are unclear. We designed this study to determine: (1) the agreement in QoL ratings between community-dwelling patients with mild to moderate dementia and family carers; and (2) the factors associated with self-reported and two types of carer-reported QoL ratings: carer-carer perspective and carer-patient perspective.

METHODS

A cross-sectional study was carried out of 80 community-dwelling patients with the diagnosis of probable Alzheimer's disease (AD) of mild or moderate severity according to NINCDS-ADRD criteria, and their 80 family carers. The QoL-AD was the primary outcome measure. We collected patients' self-reported QoL ratings and two types of carer-reported QoL ratings: carer-patient and carer-carer perspectives. Explanatory variables included demographics, lifestyle, and clinical information from patients and carers, along with cognition, awareness, psychopathology, burden-of-care, and functionality in daily life. Bland-Altman plots guided the interpretation of agreement by visualizing the distribution of all the ratings. Univariate and multivariate regression analyses were conducted to examine the contribution of candidate explanatory factors.

RESULTS

Patients and their carers showed good agreement in their QoL ratings, although the total scores of carers (regardless of perspective) were lower than the scores of patients. Depression, insight and use of anti-dementia agents were associated with QoL self-ratings, whereas cognitive function was directly associated and depression inversely associated with carers' QoL ratings.

CONCLUSION

Mild to moderate community-dwelling AD patients and their carers (with different perspectives) agree within an acceptable range in QoL ratings but the ratings are driven by different factors, and consequently are not interchangeable but complementary. They provide valuable information when used separately, not in a composite score.
