The effect of sleep disturbances on the incidence of dementia for varying lag times.

Background: Few studies have addressed the association of sleep disturbances with incident dementia with long lag times. We add to this literature by investigating how lag times varying from 2.2 to 23.

Affective Aspects of Religiousness and 6-Year Course of Depressive Symptoms in Aged Dutch Citizens.

In prospective studies on religiousness and depressive symptoms, it remains unclear whether religiousness is a predictor or parallels the fluctuating course of depressive symptoms. The current study focuses on several affective aspects of religiousness in their associations over time with late life depressive symptoms. As part of the population-based Longitudinal Aging Study Amsterdam, a subsample of 222 respondents (mean age 76.

The development of intrinsic capacity measures for longitudinal research: The Longitudinal Aging Study Amsterdam.

Background: The World Health Organization has introduced the construct of intrinsic capacity (IC) as an important component of healthy ageing and overall well-being in older adults The present study aimed to develop domain-specific and composite IC scores and to validate these scores by examining their longitudinal relation with functioning.

Methods: We used prospective data on participants aged 57 to over 90 years, with a 10-year follow-up, from the Longitudinal Aging Study Amsterdam, an ongoing cohort study of older Dutch men and women Using a formative, stepwise approach, we identified indicators across the different domains of IC, i.e.

Identification of a "Blue Zone" in the Netherlands: A Genetic, Personal, Sociocultural, and Environmental Profile.

Background And Objectives: "Blue Zones" (BZs) are regions with exceptionally high numbers of longevous inhabitants. Several factors have been suggested to promote longevity in BZs, but the evidence generally does not meet scientific quality criteria. We aimed to characterize a municipality as a "relative BZ," satisfying 3 criteria: compared to other municipalities, more exceptionally longevous inhabitants, a higher life expectancy, and a more stable population.

Reciprocal associations between depressive symptoms and satisfaction with sexual life in older adults: the roles of gender and importance attached to sexuality.

Objectives: To gain insight into the longitudinal, reciprocal associations between depressive symptoms and sexual satisfaction as well as the potential moderating roles of gender and perceived importance of sexuality.

Method: We analyzed longitudinal data from 2113 participants of the Longitudinal Ageing Study Amsterdam (LASA) with an initial age range of 54-93 years, using Generalized Estimating Equations (GEE).

Results: There were no significant associations between baseline depressive symptoms and change in sexual satisfaction, nor between baseline sexual satisfaction and change in depressive symptoms.

Joint Trajectories of Performance-Based and Self-Reported Physical Functioning in Older Adults: A 20-Year Longitudinal Study in the Netherlands.

Background: The well-known disablement process has been conceptualized as a series of transitions between progressive states of functional decline. We studied joint patterns of change within disablement states defined as walking speed, grip strength, and self-reported disability.

Methods: 1702 participants aged 65 and over were included from the Longitudinal Aging Study Amsterdam, spanning seven waves over 20 years (1996-2016).

Changes in physical performance according to job demands across three cohorts of older workers in the Longitudinal Aging Study Amsterdam.

This study set out to evaluate the association between job demands at baseline and physical performance over a six-year period across three cohorts of older Dutch workers examined 10 years apart. Data were drawn from three cohorts (1992-1999, 2002-2009 and 2012-2019) of the Longitudinal Aging Study Amsterdam. Individuals aged 55-65 years from each cohort who worked for pay were included (n = 274, n = 416, n = 618, respectively).

Social and physical neighbourhood characteristics and 10-year incidence of depression and anxiety in older adults: Results from the Longitudinal Aging Study Amsterdam.

Objective: A growing literature suggests that neighbourhood characteristics are associated with mental health outcomes, but the evidence in older adults is inconsistent. We investigated the association of neighbourhood characteristics, pertaining to demographic, socio-economic, social and physical environment domains, with the subsequent 10-year incidence of depression and anxiety, in Dutch older adults.

Methods: In the Longitudinal Aging Study Amsterdam depressive and anxiety symptoms were assessed four times between 2005/2006 and 2015/2016, using the Center for Epidemiological Studies Depression Scale (n = 1365) and the Anxiety subscale of the Hospital Anxiety and Depression Scale (n = 1420).

Health trajectories across the work exit transition in the 1990s, 2000s, and 2010s: the role of working conditions and policy.

Purpose: We examined health trajectories of Dutch older workers across their exit from the workforce in the 1990s, 2000s, and 2010s, testing the hypothesis that pre-post-exit health trajectories of workers with favourable and unfavourable working conditions increasingly diverged over time due to policy measures to extend working life.

Methods: The Longitudinal Aging Study Amsterdam includes baseline samples in 1992/1993, 2002/2003 and 2012/2013 with two 3-year follow-up waves each. Selected respondents were aged 55 years and over who exited from a paid job within the first or second 3-year interval, up to and including the statutory retirement age (N = 522).

Who live longer than their age peers: individual predictors of longevity among older individuals.

Background: There are a very few studies focusing on the individual-based survival with a long follow-up time.

Aim: To identify predictors and determine their joint predictive value for longevity using individual-based outcome measures.

Methods: Data were drawn from Tampere Longitudinal Study on Aging (TamELSA), a study of individuals' age 60-89 years (N = 1450) with a mortality follow-up of up to 35 years.

Employment trends at older ages: policy impact or secular change?

Unlabelled: 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 Netherlands) and one without PEW (Norway).

Sex and gender differences in depressive symptoms in older workers: the role of working conditions.

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.

Social position of older immigrants in the Netherlands: where do immigrants perceive themselves on the societal ladder?

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 those used in the country of settlement. In order to understand immigrants' own perception of their social position, we interviewed 23 60-68 year old immigrants from Turkish and Moroccan origin in the Netherlands.

Exploring Health Trends Prior to State Pension Age for The Netherlands up to 2040.

Background: In many Western countries, the state pension age is being raised to stimulate the extension of working lives. It is not yet well understood whether the health of older adults supports this increase. In this study, future health of Dutch adults aged 60 to 68 (i.

Predictors of resilience in older adults with lower limb osteoarthritis and persistent severe pain.

Background: Resilience refers to the process in which people function well despite adversity. Persistent severe pain may be considered an adversity in people with lower limb osteoarthritis (LLOA). The objectives of this study are: (1) to identify what proportion of older adults with LLOA and persistent severe pain show good functioning; and (2) to explore predictors of resilience.

Enjoyment of Sexuality and Longevity in Late Midlife and Older Adults: The Longitudinal Ageing Study Amsterdam.

Sexual well-being refers to the evaluation of one's sexuality. We examined the association of enjoyment of sexuality with longevity and the moderating role of perceived importance of sexuality in this association. In the population-based Longitudinal Ageing Study Amsterdam, the survival of initially 55-84-year-olds was followed during 27 years.

Prevalence of Prodromal Symptoms of Parkinson's Disease in the Late Middle-Aged Population.

Background: The prodromal phase of Parkinson's disease (PD) can last up to 20 years and is characterized by a variety of non-motor symptoms.

Objective: To determine the prevalence of a selection of non-motor symptoms known to be associated with an increased risk of developing PD in a late middle-aged population-based sample and to determine their association with motor function.

Methods: At a mean age of 60.

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 ( = 2,531), initial ages 55-85 years. Occupation was based on longest-held job.

Assessing the Robustness of Mediation Analysis Results Using Multiverse Analysis.

There is an increasing awareness that replication should become common practice in empirical studies. However, study results might fail to replicate for various reasons. The robustness of published study results can be assessed using the relatively new multiverse-analysis methodology, in which the robustness of the effect estimates against data analytical decisions is assessed.

Capturing Subjective Age, Subjective Life Expectancy, and Their Links With Older Adults' Health: The Dutch Longitudinal Aging Study Amsterdam.

This study compares the associations of two subjective lifetime perspectives, subjective age (SA) and subjective life expectancy (SLE), with physical performance, self-rated health, and depressive symptoms. 64 91-year-old participants were selected from three waves of the Longitudinal Aging Study Amsterdam (2008/09, 2011/12, 2015/16; = 1822 participants, = 3500 observations) that included graphical and numerical measures of SA and SLE. We used generalized estimating equations to examine their associations with health.

Accuracy of an algorithm to identify rheumatoid arthritis in the Longitudinal Ageing Study Amsterdam population: a validation study.

: In view of global ageing and the scarcity of knowledge about disease determinants in older individuals with rheumatoid arthritis (RA), an algorithm with optimal diagnostic accuracy was developed to identify RA patients in the Longitudinal Ageing Study Amsterdam (LASA).: Four case ascertainment algorithms were constructed and assessed for validity in LASA, an ongoing cohort study (≥ 55 years) representing the general older population of the Netherlands. Data sources used to identify the diagnosis RA were: self-reported morbidity, specialist diagnosis, and medication.
