Trends across 20 years in multiple indicators of functioning among older adults in the Netherlands.

Background: Monitoring of trends in functioning of older adults provides indispensable information for health care policy. This study examined trends in multiple indicators of functioning among Dutch older adults across a period of 20 years.

Methods: Data from the Longitudinal Aging Study Amsterdam were used.

Participation narratives of Third Age adults: Their activities, motivations and expectations regarding civil society organisations.

Third Age adults leaving the labour market are not only armed with broad experience and multiple competencies but also find themselves free of professional obligations while still physically sound. The general theory of Third Age of Laslett sheds a new light on characteristics of ageing adults and their role in society. They are able to engage in society in ways inaccessible to previous generations of older adults.

Neighbourhood social inclusion from the perspective of people with intellectual disabilities: Relevant themes identified with the use of photovoice.

Background: Earlier studies show that to gain more understanding of the concept of social inclusion, the views and experiences of people with intellectual disabilities are needed. The aim of this study was to investigate their perspective on neighbourhood social inclusion from an ecological point of view.

Method: We carried out a photovoice study with 18 people with intellectual disabilities in three neighbourhoods in the Netherlands.

A Healthy Lifestyle in Old Age and Prospective Change in Four Domains of Functioning.

The aim of this article is to study the associations between healthy lifestyle in old age and decline in physical, psychological, cognitive, and social functioning. A population-based sample of 3,107 Dutch men and women aged 55 and 85 years (1992/1993; Longitudinal Aging Study Amsterdam) was used with five 3-yeary follow-up examinations. Lifestyle score, based on smoking status, alcohol consumption, physical activity, and body mass index (BMI), ranged from 0 () to 4 ().

Living apart (or) together-neighbours' views and experiences on their relationships with neighbours with and without intellectual disabilities.

Background: Neighbours play an important role in the social inclusion of people with intellectual disabilities. Neighbouring in general might help understand the social interactions between neighbours with and without intellectual disabilities. Our study focuses on gaining insight into neighbouring patterns and how people with intellectual disabilities fit in them.

Information and Communication Technologies to Support Chronic Disease Self-Management: Preconditions for Enhancing the Partnership in Person-Centered Care.

Objective: In order to alleviate the pressure on health care systems exerted by the growing prevalence of chronic diseases, information and communication technologies (ICT) are being introduced to enable self-management of chronic diseases by supporting partnerships between patients and health care professionals. This move towards chronic disease self-management is accompanied by a shift in focus on integrating the patient with his or her perceptions on the chronic disease as a full-fledged partner into the health care system. This new perspective has been described as "person-centered care" (PCC).

Photovoice in research involving people with intellectual disabilities: A guided photovoice approach as an alternative.

Background: In studies involving people with intellectual disabilities, photovoice is increasingly used to include the voice of participants. Analysing existing literature, the present authors found that photovoice was used in various forms with different outcomes. These studies describe both obstructing and facilitating factors.

The Longitudinal Aging Study Amsterdam: cohort update 2016 and major findings.

The Longitudinal Aging Study Amsterdam (LASA) is an ongoing longitudinal study of older adults in the Netherlands, which started in 1992. LASA is focused on the determinants, trajectories and consequences of physical, cognitive, emotional and social functioning. The study is based on a nationally representative sample of older adults aged 55 years and over.

The Trade-Off between Female Fertility and Longevity during the Epidemiological Transition in the Netherlands.

Several hypotheses have been put forward to explain the relationship between women's fertility and their post-reproductive longevity. In this study, we focus on the disposable soma theory, which posits that a negative relationship between women's fertility and longevity can be understood as an evolutionary trade-off between reproduction and survival. We examine the relationship between fertility and longevity during the epidemiological transition in the Netherlands.

Socioeconomic status determines sex-dependent survival of human offspring.

Background And Objectives: In polygynous societies, rich men have many offspring through the marriage of multiple wives. Evolutionary, rich households would therefore benefit more from sons, and according to the Trivers-Willard hypothesis, parents invest more in offspring of the sex that has the best reproductive prospects. We determined the sex differences in number of offspring, sex ratio of offspring, offspring survival and offspring weight in rich and poor households in a polygynous population.

Testing evolutionary theories of discriminative grandparental investment.

This study tests two evolutionary hypotheses on grandparental investments differentiated by the child's sex: the paternity uncertainty hypothesis and the Trivers-Willard hypothesis. Data are from two culturally different countries: the Dutch Longitudinal Aging Study Amsterdam (n=2375) and the Chinese Anhui Survey (n=4026). In the Netherlands, grandparental investments are biased towards daughters' children, which is in accordance with the paternity uncertainty hypothesis.

How Grandparents Matter: Support for the Cooperative Breeding Hypothesis in a Contemporary Dutch Population.

Low birth rates in developed societies reflect women's difficulties in combining work and motherhood. While demographic research has focused on the role of formal childcare in easing this dilemma, evolutionary theory points to the importance of kin. The cooperative breeding hypothesis states that the wider kin group has facilitated women's reproduction during our evolutionary history.

When grandmothers matter.

In a recent issue of this journal, Herndon discussed the grandmother hypothesis and its implications for studies on cognitive ageing. According to this hypothesis, the long post-reproductive life span in human females is an adaptive mechanism that evolved to maximize female fitness by investing resources in the care of their grandchildren rather than by continuing to reproduce themselves. From this, Herndon deduces that special cognitive robustness to be maintained until after the age of menopause must have co-evolved because grandmothers can only exert the beneficial effect if their cognitive abilities remain intact.

Socio-economic status by rapid appraisal is highly correlated with mortality risks in rural Africa.

Socio-economic status is an important determinant of health and survival in rural Africa and necessitates a practical and valid instrument to implement in health studies. Our objective was to investigate the validity of the rapid appraisal method to assess socio-economic status and its ability to identify individuals at risk. Among 1573 households in rural northern Ghana, we calculated the Demographic Health Survey (DHS) wealth index and conducted two rapid appraisal methods: self-reported wealth and interviewer-reported wealth.

Adaptive strategies after health decline in later life: increasing the person-environment fit by adjusting the social and physical environment.

Following the press-competence model (PCM) of Lawton and associates, we tested two expectations as to the adaptations older adults make to their socio-physical environment following health decline: (1) depending on the change in their functional limitations, older adults use adaptive strategies ranging from mobilizing informal care to moving into a residential setting; (2) the more people succeed in realizing suitable adaptations, the higher their wellbeing, measured as depressive symptoms, after a health decline. Data come from two waves of a longitudinal study among Dutch people aged 60-85 and living independently at baseline (Longitudinal Aging Study Amsterdam, LASA). The 819 respondents with a decline in self-reported functional disability within 3 years time were selected for analysis.
