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.(More)
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(More)
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(More)
The authors examined eight personal and contextual conditions associated with starting new relationships with neighbors after shortand long-distance moves. A total of 625 Dutch movers and 1,936 non-movers (57–93 years old) were selected from the Longitudinal Aging Study Amsterdam. OLS linear regression analyses showed that short-distance movers mainly(More)
This article confronts the belief that, among elderly persons, living (in)dependently is equivalent to functioning (in)dependently. It has been examined to what degree the living situation of elderly persons (either living independently or in a residential home) affects the degree of social functioning (as indicated by the size of the personal network,(More)
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(More)
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(More)
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(More)
Elderly home-owners get institutionalized less often than renters do. We hypothesize that housing tenure itself explains this behavior. Using longitudinal data from a Dutch community sample (N= 2,372) collected between 1992 and 2005, we find a negative effect of housing tenure on the probability of moving to a nursing home between two subsequent waves.
