Regional differences in morbidity profiles and health care use in the oldest old: Findings from two Centenarian Studies in Portugal

Demographic transition and hospital admissions in Spanish centenarians, 2004-2020: Geographical variations and sex-related differences

BACKGROUND

This study aims to describe the distribution and temporal trends of the centenarian population and their hospital admissions in Spain over the past two decades, focusing on regional and sex-based differences.

METHODS

A retrospective study was conducted using data from the Spanish National Health System's Hospital Discharge Records-Minimum Basic Data Set. The analysis included all hospitalized patients ≥100 years between January 2004 and December 2020. The crude annual centenarian population and admission rates were calculated. Joinpoint regression analysis and cross-correlation analysis were used to identify trends and associations.

RESULTS

From 2004 to 2020, the centenarian population in Spain increased by 89.0 %, with a larger increase observed in women (86.6 %) than men (32.9 %). Significant geographic variability was found, with rates from 1.1 to 5.2 × 10,000 inhabitants per year across different regions. Joinpoint analysis identified three trends: a decline from 2004 to 2008, an increase from 2008 to 2015, and a slower increase from 2015 to 2020. Hospital admissions of centenarians increased by 121.5 %, with a larger increase in women than men (212.1% vs 90.7 %); women represented 75.4 % of admissions. The proportion of centenarian admissions to total hospitalizations showed an upward trend until 2015 and then stabilized; it also varied among regions.

CONCLUSION

There was a significant increase in the centenarian population and hospital admissions of centenarians in Spain. There are regional disparities in their distribution, with women representing a larger proportion of centenarians and hospital admissions. Understanding these trends and differences is crucial for implementing interventions that ensure adequate healthcare for centenarians.

Health care utilization in very advanced ages: A study on predisposing, enabling and need factors

This study aims to examine the effects of predisposing, enabling, and need factors on healthcare utilization in advanced age. Data from a sample of 270 Portuguese community-dwelling persons aged ≥80 years was used. Face-to-face interviews were conducted and included the application of a research protocol addressing a set of sociodemographic and health-related variables that expressed the Andersen Behavioral model (i.e., predisposing, enabling, and need factors). Predictors of visits to general practitioners (GP) and specialist physicians, as well as emergency department (ED) use and hospitalizations were investigated. Multivariate linear and logistic regression analyzes were used to model the effects of predictor factors specified in the Andersen Behavioral model. Our findings underscore that younger age and having multimorbidity were significantly associated with having GP visits. Specialist physician visits were associated with younger age and a higher number of daily medications. ED use was associated with being male, having formal social support and a higher number of daily medications. Hospitalizations were associated with being younger, being male and having multimorbidity. Our findings revealed that need and predisposing factors determined the most healthcare use.

The Great Escape. Centenarians' exceptional health

BACKGROUND

Centenarians escapers are those who reached 100 years of age without the diagnosis of any of the common age-related diseases and exploring their characteristics will inform about successful ageing. No previous study has examined centenarians free of common chronic diseases amongst New Zealand centenarians.

METHODS

Retrospective observational cross-sectional review of a national dataset determining the prevalence of depression, dementia, diabetes and hypertension, smoking, physical activity and social relationships among older adults (aged 60-99 years) and centenarians. Participants were all older New Zealanders living independently in the community who completed the international Residential Assessment Instrument-Home Care (interRAI-HC) assessment during the study's 5-year period (July 2013-June 2018).

RESULTS

The assessments of 292 centenarians (mean age 101.03, SD 1.27 years) and 103,377 elderly (mean age 81.7, SD 5.7 years) were analysed. Compared to the elderly, centenarians were more likely to be female (74.7%, compared with 59.3% elderly, p < 0.001). Centenarians free of common chronic diseases did not differ from other centenarians on any of the analysed variables. Reduction in smoking rates and steady high rates of social engagement were associated with reaching a centenarian status free of common chronic diseases compared with older adults.

CONCLUSIONS

Not smoking and being socially engaged throughout older age were associated with being a centenarian free of common chronic diseases. This study adds to our understanding the complexities of attaining exceptional longevity.

Family Functionality, cognitive status and social participation are related to survival in nonagenarians and centenarians: data from a Brazilian cohort study

Aim: To evaluate whether family functionality, using the instrument “Adaptation, Partnership, Growth, Affection, and Resolve” (APGAR) and its components, as well as other health indicators, influences the survival of nonagenarians and centenarians. Methods: Participants were randomly identified and evaluated in their homes of Porto Alegre — Brazil. Death or survival information were verified by telephone or death registry system. Follow-up time measured the number of months between the first evaluation and the date of death or the last contact. Participants with APGAR ≥ 7 were classified with good functionality. The APGAR components were analyzed as yes or no. Results: Two-hundred-fourteen participants (73% women, age 92.4±3.59 years) were followed during 23±10.0 months. Sixty-on (28.5%) died. Survivors were younger (p<0.001), had better cognitive performance (p<0.001), and reported more frequently leaving home (p=0.010) and participating in social activities (p<0.001). Survivors had a similar frequency for good family functioning (90% p=0.994), but more often they were satisfied with their family time (p=0.032) and with the way the family showed affection and reacted to their feelings (p=0.083). Conclusions: Family affection and time were significantly associated with lower hazard-ratio, even adjusted for age, as well as cognitive performance, social activities and the habit of leaving home. In addition to the preservation of cognitive performance, to remain physically and socially active, family support is related to the higher survival rate in nonagenarians and centenarians in Brazil.

Resilience in Very Advanced Ages: A Study With Centenarians

This study intends to assess the relationship between resilience in extremely long-lived individuals and sociodemographic, cognitive and health status variables, and significant life events. A selected sample of 48 centenarians (mean age = 100.8 years, SD = 1.2; 83.3% female) from two centenarian studies was considered. A resilience score covering five items (aging and usefulness, hopefulness, worryness, loneliness, and control) was considered. Multivariable linear regression analyses were conducted in order to identify predictors of resilience. No significant differences in the resilience score regarding sociodemographic variables or typology of significant life events were found. Our findings underscore that health perception (better) and pain (less frequent) were associated with higher levels of resilience. In being present in extremely long-lived individuals, resilience should be object of interest in further research.

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.
