Older Turkish and Moroccan immigrants are often ascribed a low social position based on their relatively unfavourable educational level, occupational status and income. Yet immigrants emigrated to improve their social position and came from contexts where determinants of social position might be based on different socio-cultural circumstances than...
Article
Full-text available
Background Female older workers generally leave the work force earlier than men. Depressive symptoms are a risk factor of early work exit and are more common in women. To extend working lives, pathways leading to these sex inequalities need to be identified. The aim of this study was to investigate the association of sex and gender with depressive...

Introduction Age-related declines in multiple facets of sexuality in later life are well documented. However, most studies have been cross-sectional with data collected at one point in time, leaving questions about cohort differences and interrelated historical changes in physical health and psychosocial functioning unanswered. Methods We examined...
Article
Full-text available
Observed increases in retirement age are generally attributed to policies to extend working lives (PEW). In a quasi-experimental design, we examine to what extent increases in employment of older workers can be attributed to secular changes in individual characteristics as opposed to PEW. We compare two countries: one with clear PEW (the Netherland...

Article
Full-text available
Introduction: Frailty can be seen as a continuum, from fit to frail. While many recent studies have focused on frailty, much less attention has been paid to the other end of the continuum: the group of older adults that remain (relatively) vital. Moreover, there is a lack of studies on frailty and vitality that investigate predictors from multiple...
Article
Samenvatting Door de recente verhoging van de AOW-leeftijd in Nederland is een nieuwe groep ontstaan: de betaald werkenden tussen de oude AOW-leeftijd van 65 jaar en de nieuwe AOW-leeftijd, de ‘65-pre-AOW’ers’. In een eerste kenschets van deze groep vergelijken wij hun werk- en individuele kenmerken met die van de 61-64-jarige werkers, de ‘61-64’er...
