Whom Do Centenarians Rely on for Support? Findings From the Second Heidelberg Centenarian Study

ABSTRACT

This paper provides a detailed picture of the sources and types of informal support available to centenarians, depending on their housing and care arrangements. Participants were 112 centenarians and 96 primary contacts of centenarians enrolled in the population-based Second Heidelberg Centenarian Study. Findings indicate that children of centenarians were their primary source of support in daily life. Those without living children had overall less help. Most frequently reported was help with administrative tasks, regardless of centenarians’ residence or living arrangement. All other types of help (e.g., with activities of daily living and housework) were reported by about one-third and were mostly provided by children; centenarians without children were more likely to have friends/neighbors involved in some of these tasks. The one category reported by a third of the centenarians regardless of residence, living arrangements, or presence of a child was help with socializing/companionship. Findings constitute an important step toward identifying and meeting the support needs of centenarians and their families. Policy implications are discussed.     

Challenges Experienced at Age 100: Findings From the Fordham Centenarian Study

ABSTRACT

This article examines the challenges experienced by very old individuals and their consequences for well-being and mental health. In order to capture unique issues experienced in very old age, 75 participants of the population-based Fordham Centenarian Study answered open-ended questions on everyday challenges. Theme-based coding was then used to categorize and quantify responses. The challenges mentioned most often were challenges faced in the functional (e.g., physical health/activities of daily living restrictions, mobility, sensory impairment), psychological (e.g., loss of well-liked activity, dependency, negative emotions, death), and social (e.g., family loss) life domains. Functional challenges were negatively associated with aging satisfaction and positively associated with loneliness. Psychological challenges were positively linked to aging satisfaction. Social challenges were marginally related to loneliness. Notably, challenges were not related to depression. In conclusion, the challenges experienced in very old age are multidimensional and multifaceted, unique in nature, and have differential relations to mental health. Functional, psychological, and social challenges affect very old individuals’ lives and therefore need to be better understood and addressed. Given their consequences, it is imperative for policy makers to develop an awareness for the different types of challenges faced by centenarians, as there may be unique policy implications related to each.     

Understanding Very Old Age: Looking Back and Thinking Forward

ABSTRACT

Understanding human development among the oldest old is a sequential building process taking into account building-block data, theories, and models from childhood, adulthood, and old age toward a new territory of oldest-old survivors who have lived way beyond the average life-span. A central question is whether the oldest-old survivors have developed specific survival techniques and/or protective environments that nurture survival. Or are the oldest old statistical outliers who by happenstance continue to survive further into old age? This commentary provides a historical framework on the papers in this series that describe challenges confronted by the oldest-old survivors in order to advance our understanding of survival of the oldest old. A clear understanding of the contributors to longevity could guide public policies toward well-being and life satisfaction among our oldest-old citizens.     

Life at Age 100: An International Research Agenda for Centenarian Studies

ABSTRACT

Living a long life is desired by many individuals, and this dream is likely to become reality in more and more industrialized societies. During the past 3 decades, the number of very old individuals has increased significantly, creating a global demographic challenge with consequences at the individual, family, and societal levels. Yet, life in very old age is still poorly understood in terms of its unique characteristics and challenges. Besides specific content areas, very old age represents an understudied field of research. This lack of knowledge may be one reason that the very old also are an underserved population. This special issue introduces an international network of three centenarian studies that describe and compare the life circumstances and characteristics of centenarians across Germany, Portugal, and the United States. Our parallel studies comprehensively assess centenarians’ physical, cognitive, social, and psychological functioning to create a knowledge base regarding their capacities and needs. A specific focus lies in the investigation of psychological aspects, social resources, and societal/cultural contexts, factors that may contribute to longevity and successful aging. Determining key characteristics of this very old population and investigating similarities and differences across countries is timely and urgent, both from an applied and a policy standpoint.     

The Population of Centenarians in Brazil: Historical Estimates from 1900 to 2000

Since the nineteenth century, the census has provided the number of 100-year-olds in Brazil, one of the most populous countries worldwide. In 1900, 4,438 individuals reported themselves to be centenarians, a figure that increased about fivefold by the 2000 census. However, due to data quality issues, we are skeptical about the real size of the recorded population in the Brazilian census. We offer alternative estimates of the most likely number of centenarians during the twentieth century by combining variable-r relations with different mortality models. Our results indicate there was virtually no centenarian at the beginning of the twentieth century. The population has become larger than 1,000 individuals only in the 1990s, suggesting there has been an extensive, although diminishing, overenumeration of centenarians in the census records. Our results can help policymakers to plan the demands of a growing old age population in places that face stricter family and public budget constraints.     

Health Status,Living Arrangements,and Service Use at 100: Findings From the Oporto Centenarian Study

ABSTRACT

This paper describes the sociodemographic characteristics, health status, and service use of centenarians living in the community and centenarians residing in an elder care facility/nursing home and examines their main differences. Participants were 140 centenarians from the population-based Oporto Centenarian Study (M_age = 101.2; SD = 1.6). Main findings revealed that the majority of the centenarians lived at home with their family members (57.9%). Increased health care needs, living alone, and family caregiving constraints were the most common reasons for entering a nursing home. Community-dwelling centenarians were cared for mostly by their children and were less dependent and in better cognitive health than those who resided in a nursing home. Differences were found in the pattern of health service use according to the centenarians’ residence, ability to pay medical expenses, and dependency level. Findings highlight the need for an accurate assessment of caregiving support systems, particularly family intergenerational duties, and of the factors constraining the access and use of health and social services. Policy makers may be guided by the insights gained from this research and work toward improvement of support options and removal of barriers to service access.     

Relative Income,Race, and Fertility

If a white husband's income is higher than expected for men of his age, race, education, job characteristics, and region, economic theory predicts higher complete fertility for his wife. In the present study one per cent public use samples from the 1970 Census for California and Hawaii were used to examine the effect of relative income on Japanese, Chinese, and black fertility. Relative income was defined in two ways: (1) with regard to earnings of husbands of the same race, education, employment, and state; (2) with regard to earnings of white husbands of the same education, employment, and state. High relative incomes defined in each way were associated with increased completed fertility of Japanese and Chinese in Hawaii, where Orientals form a majority. Neither definition of high relative income was associated with the completed fertility of Japanese, Chinese, or blacks in California, where non-whites form a minority. The results suggest that the effect of relative income on fertility for a racial group will be positive only where there are few racial barriers to their attainment of high incomes.
