Occupation-Based Life Expectancy:Actuarial Fairness in Determining Statutory Retirement Age
This study examines occupation-based differences in life expectancy and the extent to which health accounts for these differences. Twentyseven-year survival follow-up data were used from the Dutch population-based Longitudinal Aging Study Amsterdam (n = 2,531), initial ages 55â85Â years. Occupation was based on longest-held job. Results show that the non-skilled general, technical and transport domains had an up to 3.5-year shorter life expectancy than the academic professions, accounting for the compositional characteristics age and gender. Statutory retirement age could be made to vary accordingly, by allowing a proportionally greater pension build-up in the shorter-lived domains. Health accounted for a substantial portion of the longevity difference, ranging from 20 to 66%, depending on the health indicator. Thus, health differences between occupational domains today can be used as a means to tailor retirement ages to individualsâ risks of longevity. These data provide a proof of principle for the development of an actuarially fair method to determine statutory retirement ages
Predictors of entering a hearing aid evaluation period: a prospective study in older hearing-help seekers
This study aimed to determine the predictors of entering a hearing aid evaluation period (HAEP) using a prospective design drawing on the health belief model and the transtheoretical model. In total, 377 older persons who presented with hearing problems to an ENT-specialist (n = 110) or a hearing aid dispenser (n = 267) filled in a baseline questionnaire. After four months, it was determined via a telephone interview whether or not participants had decided to enter a HAEP. Multivariable logistic regression analyses were applied to determine which baseline variables predicted HAEP status. A priori, candidate predictors were divided into âlikelyâ and ânovelâ predictors based on the literature. The following variables turned out to be significant predictors: more expected hearing aid benefits, greater social pressure, and greater self-reported hearing disability. In addition, greater hearing loss severity and stigma were predictors in women but not in men. Of note, the predictive effect of self-reported hearing disability was modified by readiness such that with higher readiness, the positive predictive effect became stronger. None of the ânovelâ predictors added significant predictive value. The results support the notion that predictors of hearing aid uptake are also predictive of entering a HAEP. This study shows that some of these predictors appear to be gender-specific or are dependent on a personâs readiness for change. After assuring the external validity of the predictors, an important next step would be to develop prediction rules for use in clinical practice, so that older personsâ hearing help seeking journey can be facilitated
LASA: Langer doorwerken is voor 50 procent met gezondheidsbeperkingen
Al jaren stimuleert de overheid oudere werkenden om langer door te werken. De gemiddelde uittreedleeftijd is hiermee gestegen van 61 jaar in 2006 naar 64,5 jaar in 2016. In een recent onderzoek met gegevens van de Longitudinal Aging Study Amsterdam (LASA) is onderzocht in hoeverre de stijging van de uittreedleeftijd samen is gegaan met een toename in het aantal jaren dat men met gezondheidsbeperkingen doorwerkt
The role of extracerebral cholesterol homeostasis and ApoE e4 in cognitive decline
AbstractWe examined the associations between extracerebral markers of cholesterol homeostasis and cognitive decline over 6 years of follow-up, and studied the modifying effect of apolipoprotein E (ApoE) e4. Data were collected in the Longitudinal Aging Study Amsterdam (n = 967, with longitudinal data on cognition, ages ℠65 years) and analyzed using linear mixed models. General cognition (Mini-Mental State Examination; MMSE), memory (Auditory Verbal Learning Test), and information processing speed (Coding task) were measured. The results show that ApoE e4 was a significant effect modifier. Significant associations were found only in ApoE e4 noncarriers (n = 718). We found a nonlinear negative association between the ratio of lanosterol to cholesterol (†189.96 ng/mg), a marker for cholesterol synthesis, and general cognition. Lower cholesterol absorption, i.e., lower ratios of campesterol and sitosterol to cholesterol, as well as a higher rate of cholesterol synthesis relative to absorption were associated with lower information processing speed. In ApoE e4 carriers, the negative association between the ratio of campesterol to cholesterol and memory reached borderline significance. Future research should focus on the interaction between (disturbed) cholesterol homeostasis and ApoE e4 status with respect to dementia
Trajectories of Big Five Personality Traits: A Coordinated Analysis of 16 Longitudinal Samples
This study assessed change in selfâreported Big Five personality traits. We conducted a coordinated integrative data analysis using data from 16 longitudinal samples, comprising a total sample of over 60 000 participants. We coordinated models across multiple datasets and fit identical multiâlevel growth models to assess and compare the extent of trait change over time. Quadratic change was assessed in a subset of samples with four or more measurement occasions. Across studies, the linear trajectory models revealed declines in conscientiousness, extraversion, and openness. Nonâlinear models suggested lateâlife increases in neuroticism. Metaâanalytic summaries indicated that the fixed effects of personality change are somewhat heterogeneous and that the variability in trait change is partially explained by sample age, country of origin, and personality measurement method. We also found mixed evidence for predictors of change, specifically for sex and baseline age. This study demonstrates the importance of coordinated conceptual replications for accelerating the accumulation of robust and reliable findings in the lifespan developmental psychological sciences. © 2020 European Association of Personality PsychologyPeer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/156004/1/per2259.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/156004/2/per2259-sup-0001-Data_S1.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/156004/3/per2259-sup-0002-Open_Practices_Disclosure_Form.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/156004/4/per2259_am.pd
Associations between perceived neighbourhood problems and quality of life in older adults with and without osteoarthritis:Results from the Hertfordshire cohort study
This study examined whether the association of quality of life (QoL) with perceived neighbourhood problems is stronger in older adults with osteoarthritis (OA) than in those without OA. Of all 294 participants, 23.8% had OA. More perceived neighbourhood problems were associated with a stronger decrease in QoL over time in participants with OA (B=-0.018; p=0.02) than in those without OA (B=-0.004; p=0.39). Physical activity did not mediate this relationship. Older adults with OA may be less able to deal with more challenging environments

Predictors in starting and stopping Internet use between 2002 and 2012 by Dutch adults 65 years and older
Research has indicated the need to consider the ageing process with technology adoption by older adults.
This study examined psychological, health, social and demographic predictors with starting and stopping
Internet use by older adults (2002â2012). Data were used from the Longitudinal Aging Study Amsterdam,
and Cox regression analyses were done to test predictors over time with starting or stopping Internet
use. The results indicated that older adults starting to use the Internet (11.6%) outnumbered those who
stopped (3.1%). Psychological, health, social and demographic predictors separately predicted starting and
stopping Internet use. Starting use was predicted by lower age, higher education, normal cognition and living
alone. The predictors in stopping use were being younger, having a high sense of mastery and being higher
educated. The results need to be interpreted as indicative due to the small number of stoppers. Suggestions
are made on how to improve usability
Who will become my co-residents? The role of attractiveness of institutional care in the changing demand for long-term care institutions
Background: In several OECD countries the percentage of people over 80 in LTC institutions has been declining for more than a decade, despite population ageing. The standard model to explain healthcare utilization, the Andersen model, cannot explain this trend. We extend the Andersen model by including proxies for the relative attractiveness of community living compared to institutional care. Using longitudinal data on long-term care use in the Netherlands from 1996 to 2012, we examine to what extent a decline in institutional care is associated with changes in perceived attractiveness of institutional LTC care compared to community living. Methods: With a BlinderâOaxaca decomposition regression, we decomposed the difference in admission to LTC institutions between the period 1996â1999 and 2009â2012 into a part that accounts for differences in predictors of the Andersen model and an âunexplainedâ part, and investigate whether the perceived attractiveness of institutional care reduces the size of the unexplained part. Results: We find that factors related to the perceived attractiveness of institutional care compared to community living explains 12.8% of the unexplained negative time trend in admission rates over the total period (1996â2012), and 19.1â19.2% over shorter time frames. Discussion: Our results show that changes in the perceived attractiveness of institutional LTC may explain part of the decline in demand for institutional care. Our findings imply that policies to encourage community living may have a self-reinforcing effect
