Trends in risk factors for coronary heart disease in the Netherlands

BACKGROUND

Favourable trends in risk factor levels in the general population may partly explain the decline in coronary heart disease (CHD) morbidity and mortality. Our aim was to present long-term national trends in established risk factors for CHD.

METHODS

Data were obtained from five data sources including several large scale population based surveys, cohort studies and general practitioner registers between 1988 and 2012. We applied linear regression models to age-standardized time trends to test for statistical significant trends. Analyses were stratified by sex and age (younger <65 and older ≥65 years adults).

RESULTS

The results demonstrated favourable trends in smoking (except in older women) and physical activity (except in older men). Unfavourable trends were found for body mass index (BMI) and diabetes mellitus prevalence. Although systolic blood pressure (SBP) and total cholesterol trends were favourable for older persons, SBP and total cholesterol remained stable in younger persons.

CONCLUSIONS

Four out of six risk factors for CHD showed a favourable or stable trend. The rise in diabetes mellitus and BMI is worrying with respect to CHD morbidity and mortality.

Trend study on the association between hospital admissions and the health of Dutch older adults (1995-2009)

OBJECTIVES

An increase in hospital admission rates in older people may reflect improved access to healthcare, but also declining health trends in the older population. Owing to a lack of individual-level data, the latter possibility has received little attention. The current study examines associations between health status and hospitalisation rates of older adults in the Netherlands.

DESIGN

Observational individual-level data linked to hospital register data.

SETTING

Data from 1995 to 2009 from the nationally representative Longitudinal Aging Study Amsterdam were linked to the Dutch Hospital Discharge Register.

PARTICIPANTS

A total of 5681 observations of 2520 respondents across 4 measurement points (each with a follow-up of 36 months; ages 65-88 years).

OUTCOME MEASURES

The contribution of health, demographic, psychosocial and lifestyle characteristics to time trends in hospitalisation was assessed in multivariate models.

RESULTS

Between 1995 and 2009, the percentage with 1 or more overnight admissions (planned or acute) increased slightly from 38.1% to 39.7%. This was due to an increase in acute admission only (22.2-27.0%). Increased prevalences of chronic diseases, functional limitations and polypharmacy accounted for part of the observed increase in acute admissions. In addition, a more than doubled prevalence of day admissions over time was observed (12.3-28.3%), a trend that was unrelated to changes in individual characteristics.

CONCLUSIONS

This trend study showed a contribution of declines in population health to increases in acute hospital admissions. Since these declines did not provide a full explanation, healthcare reforms and increases in treatment possibilities in this period are likely to have contributed as well.

Changes in admission to long-term care institutions in the Netherlands: comparing two cohorts over the period 1996-1999 and 2006-2009

Using data from two cohorts, we examine to what extent a decline in institutional care in the Netherlands is associated with changes in the need for care and/or societal factors. We compared older adults, aged 65–89, who were admitted to a long-term care (LTC) institution in the period 1996–1999 and 2006–2009. Using the Andersen model, we tested per block of predisposing, enabling and need factors, which factors were significant predictors of admission to institutional care. With a Blinder–Oaxaca decomposition regression, we decomposed the difference in admission to an LTC institution between the period 1996–1999 and 2006–2009 into a part that is due to differences in health needs and other factors such as effect of policy, social values, and technology. Between 1996 and 2006, the percentage of co-residing partners and income increased and the average level of loneliness decreased significantly. The prevalence of disability, chronic diseases, however, increased. Whereas the care by partners declined, the formal care by professionals increased. Although the observed decline in the admission rate to institutional care was relatively small across the 10 years (from 5.3 % in 1996–1999 to 4.5 % in 2006–2009, a 15 % decrease), the probability of admission in 2006–2009 was relatively much lower when accounting for changes in the health and social conditions of the participants: the probability was 1.7–2.1 % point lower for adults in the period 2006–2009 compared to 1996–1999, a 32–40 % decrease. Our results show that the decline in the admission rate to LTC institutions is not the result of changes in need. The decline is suggested to be the combined effect of changes in policy, technological advances and changes in social norms.

Impact of loneliness and depression on mortality: results from the Longitudinal Ageing Study Amsterdam

BACKGROUND

Loneliness is highly prevalent among older people, has serious health consequences and is an important predictor of mortality. Loneliness and depression may unfavourably interact with each other over time but data on this topic are scarce.

AIMS

To determine whether loneliness is associated with excess mortality after 19 years of follow-up and whether the joint effect with depression confers further excess mortality.

METHOD

Different aspects of loneliness were measured with the De Jong Gierveld scale and depression with the Centre for Epidemiologic Studies Depression Scale in a cohort of 2878 people aged 55-85 with 19 years of follow-up. Excess mortality hypotheses were tested with Kaplan-Meier and Cox proportional hazard analyses controlling for potential confounders.

RESULTS

At follow-up loneliness and depression were associated with excess mortality in older men and women in bivariate analysis but not in multivariate analysis. In multivariate analysis, severe depression was associated with excess mortality in men who were lonely but not in women.

CONCLUSIONS

Loneliness and depression are important predictors of early death in older adults. Severe depression has a strong association with excess mortality in older men who were lonely, indicating a lethal combination in this group.

Religious Involvement and 6-Year Course of Depressive Symptoms in Older Dutch Citizens:

Objectives: Expanding on cross-sectional studies, associations are examined between religious involvement and the 6-year course of depressive symptoms in older adults. Methods: Subjects are 1,840 community-dwelling older adults (aged 55 to 85) participating in three measurement cycles of the Longitudinal Aging Study, Amsterdam. Assessments include aspects of religious involvement, depressive symptoms, physical health, self-perceptions, social integration, urbanization, and alcohol use. Results: Church attendance is negatively associated with the course of depressive symptoms, also after adjustment for explanatory variables. Among respondents with functional limitations, lower depression scores are found for those who attend church on a regular basis. For respondents who are bereaved or nonmarried, however, slightly higher depression scores are found for those with high levels of orthodox beliefs. Discussion: There is a consistent negative association over time between church attendance and depressive symptoms in older Dutch citizens. Both stress-buffering as well as depression-evoking effects of religious involvement are found.

Impact of clinical osteoarthritis of the hip, knee and hand on self-rated health in six European countries: the European Project on OSteoArthritis

PURPOSE

Osteoarthritis (OA) has been shown to be associated with decreased physical function, which may impact upon a person's self-rated health (SRH). Only a few studies have examined the association between OA and SRH in the general population, but to date none have used a clinical definition of OA. The objectives are: (1) To examine the cross-sectional association between clinical OA and fair-to-poor SRH in the general population; (2) To examine whether this association differs between countries; (3) To examine whether physical function is a mediator in the association between clinical OA and SRH.

METHODS

Baseline data of the European Project on OSteoArthritis (EPOSA) were used, which includes pre-harmonized data from six European cohort studies (n = 2709). Clinical OA was defined according to the American College of Rheumatology criteria. SRH was assessed using one question: How is your health in general? Physical function was assessed using the Western Ontario and McMaster Universities OA Index and Australian/Canadian OA Hand Index.

RESULTS

The prevalence of fair-to-poor SRH ranged from 19.8 % in the United Kingdom to 63.5 % in Italy. Although country differences in the strength of the associations were observed, clinical OA of the hip, knee and hand were significantly associated with fair-to-poor SRH in five out of six European countries. In most countries and at most sites, the association between clinical OA and fair-to-poor SRH was partly or fully mediated by physical function.

CONCLUSIONS

Clinical OA at different sites was related to fair-to-poor SRH in the general population. Most associations were (partly) mediated by physical functioning, indicating that deteriorating physical function in patients with OA should be a point of attention in patient care.

Predictors of social leisure activities in older Europeans with and without multimorbidity

Older people spend much time participating in leisure activities, such as taking part in organized activities and going out, but the extent of participation may differ according to both individual and environmental resources available. Chronic health problems become more prevalent at higher ages and likely necessitate tapping different resources to maintain social participation. This paper compares predictors of participation in social leisure activities between older people with and those without multimorbidity. The European Project on Osteoarthritis (EPOSA) was conducted in Germany, UK, Italy, The Netherlands, Spain and Sweden (N = 2942, mean age 74.2 (5.2)). Multivariate regression was used to predict social leisure participation and degree of participation in people with and without multimorbidity. Fewer older people with multimorbidity participated in social leisure activities (90.6 %), compared to those without multimorbidity (93.9 %). The frequency of participation was also lower compared to people without multimorbidity. Higher socioeconomic status, widowhood, a larger network of friends, volunteering, transportation possibilities and having fewer depressive symptoms were important for (the degree of) social leisure participation. Statistically significant differences between the multimorbidity groups were observed for volunteering and driving a car, which were more important predictors of participation in those with multimorbidity. In contrast, self-reported income appeared more important for those without multimorbidity, compared to those who had multimorbidity. Policies focusing on social (network of friends), physical (physical performance) and psychological factors (depressive symptoms) and on transportation possibilities are recommended to enable all older people to participate in social leisure activities.

Common trajectories of physical functioning in the Doetinchem Cohort Study

PURPOSE

to describe common trajectories of physical functioning and their determinants among an adult cohort, followed over a period of 15 years.

METHODS

the study sample consisted of 4,123 participants (initial ages 26-70 years) from the Doetinchem Cohort Study, who participated in three or four measurement cycles. Physical functioning was measured with the Dutch version of the SF-36. Using a group-based modelling strategy, trajectories of physical functioning were determined. Weighted multinomial logistic regression analyses were performed to identify socio-demographic, lifestyle and health characteristics that differentiate between the trajectories at baseline.

RESULTS

five common physical functioning trajectories were distinguished, labelled as 'stable not limited' (27% of the population), 'stable slightly limited' (54%), 'slightly limited substantial deterioration' (7%), 'moderately limited gradual improvement' (9%) and 'stable severely limited' (3%). The characteristics that differentiate between the trajectories with limitations and the trajectory 'stable not limited' were being female, older, physically inactive, overweight or obese, having one or more chronic conditions, poor mental health and poor self-perceived health at baseline. Being younger, physically active, less obese, living with a partner and a good perceived health were characteristics of the trajectory 'moderately limited gradual improvement' compared with 'stable severely limited'.

CONCLUSION

five common trajectories of physical functioning were distinguished in an adult cohort, with most individuals following a stable but slightly limited course of physical functioning. Some early risk indicators were found that in the future might be used to early identify those with limitations in physical functioning.

Effectiveness of a Geriatric Care Model for frail older adults in primary care: Results from a stepped wedge cluster randomized trial

BACKGROUND

Primary care-based comprehensive care programs have the potential to improve outcomes in frail older adults. We evaluated the impact of the Geriatric Care Model (GCM) on the quality of life of community-dwelling frail older adults.

METHODS

A 24-month stepped wedge cluster randomized controlled trial was conducted between May 2010 and March 2013 in 35 primary care practices in the Netherlands, and included 1147 frail older adults. The intervention consisted of a geriatric in-home assessment by a practice nurse, followed by a tailored care plan. Reassessment occurred every six months. Nurses worked together with primary care physicians and were supervised and trained by geriatric expert teams. Complex patients were reviewed in multidisciplinary consultations. The primary outcome was quality of life (SF-12). Secondary outcomes were health-related quality of life, functional limitations, self-rated health, psychological wellbeing, social functioning and hospitalizations.

RESULTS

Intention-to-treat analyses based on multilevel modeling showed no significant differences between the intervention group and usual care regarding SF-12 and most secondary outcomes. Only for IADL limitations we found a small intervention effect in patients who received the intervention for 18months (B=-0.25, 95%CI=-0.43 to -0.06, p=0.007), but this effect was not statistically significant after correction for multiple comparisons.

CONCLUSION

The GCM did not show beneficial effects on quality of life in frail older adults in primary care, compared to usual care. This study strengthens the idea that comprehensive care programs add very little to usual primary care for this population.

Role of vision loss, functional limitations and the supporting network in depression in a general population

PURPOSE

Although the prevalence of depression in visually impaired older persons is high, the association between vision loss and depression seems to be influenced by factors other than visual impairment. In this study, the role of vision loss, functional limitations and social network characteristics in relation to depressive symptoms was investigated.

METHODS

Cross-sectional data (N = 1237) from the Longitudinal Aging Study Amsterdam were used to investigate the prevalence of depression (Center of Epidemiological Studies-Depression scale) within subgroups with increasing vision loss. In linear regression models, functional limitations and social network characteristics were examined as possible mediators in the association between vision loss and depression. Having a partner was considered to be a potential moderator.

RESULTS

Although a significant linear trend was found in the presence of depressive symptoms with 14% in normally sighted, 23% in mild and 37% in severe vision loss (χ(2)(1) = 14.9; p < 0.001), vision loss was not an independent determinant of depression. Mediators were functional limitations (p < 0.001) and social network size (p = 0.009). No interaction with partner status was found.

CONCLUSION

In the presence of depression, a trend was found with increasing severity of vision loss, indicating the need for more attention in (mental) health care and low-vision rehabilitation. In the general older population, vision loss was not an independent determinant of depression but was mediated by functional limitations and social network size. Rather than receiving actual social support, the idea of having a social network to rely on when needed seemed to be associated with lower levels of depression.

Mixed care networks of community-dwelling older adults with physical health impairments in the Netherlands

As part of long-term care reforms, home-care organisations in the Netherlands are required to strengthen the linkage between formal and informal caregivers of home-dwelling older adults. Information on the variety in mixed care networks may help home-care organisations to develop network type-dependent strategies to connect with informal caregivers. This study first explores how structural (size, composition) and functional features (contact and task overlap between formal and informal caregivers) contribute to different types of mixed care networks. Second, it examines to what degree these network types are associated with the care recipients' characteristics. Through home-care organisations in Amsterdam, the Netherlands, we selected 74 frail home-dwelling clients who were receiving care in 2011-2012 from both informal and formal caregivers. The care networks of these older adults were identified by listing all persons providing help with five different types of tasks. This resulted in care networks comprising an average of 9.7 caregivers, of whom 67% were formal caregivers. On average, there was contact between caregivers within 34% of the formal-informal dyads, and both caregivers carried out at least one similar type of task in 29% of these dyads. A principal component analysis of size, composition, contact and task overlap showed two distinct network dimensions from which four network types were constructed: a small mixed care network, a small formal network, a large mixed network and a large formal network. Bivariate analyses showed that the care recipients' activities of daily living level, memory problems, social network, perceived control of care and level of mastery differed significantly between these four types. The results imply that different network types require different actions from formal home-care organisations, such as mobilising the social network in small formal networks, decreasing task differentiation in large formal networks and assigning co-ordination tasks to specific dyads in large mixed care networks.

Vitamin D and Memory Decline: Two Population-Based Prospective Studies

BACKGROUND

Vitamin D deficiency has been linked with dementia risk, cognitive decline, and executive dysfunction. However, the association with memory remains largely unknown.

OBJECTIVE

To investigate whether low serum 25-hydroxyvitamin D (25(OH)D) concentrations are associated with memory decline.

METHODS

We used data on 1,291 participants from the US Cardiovascular Health Study (CHS) and 915 participants from the Dutch Longitudinal Aging Study Amsterdam (LASA) who were dementia-free at baseline, had valid vitamin D measurements, and follow-up memory assessments. The Benton Visual Retention Test (in the CHS) and Rey's Auditory Verbal Learning Test (in the LASA) were used to assess visual and verbal memory, respectively.

RESULTS

In the CHS, those moderately and severely deficient in serum 25(OH)D changed -0.03 SD (95% CI: -0.06 to 0.01) and -0.10 SD (95% CI: -0.19 to -0.02) per year respectively in visual memory compared to those sufficient (p = 0.02). In the LASA, moderate and severe deficiency in serum 25(OH)D was associated with a mean change of 0.01 SD (95% CI: -0.01 to 0.02) and -0.01 SD (95% CI: -0.04 to 0.02) per year respectively in verbal memory compared to sufficiency (p = 0.34).

CONCLUSIONS

Our findings suggest an association between severe vitamin D deficiency and visual memory decline but no association with verbal memory decline. They warrant further investigation in prospective studies assessing different memory subtypes.

[We are living longer, but are these additional years spent in good health?]

Life expectancy in western countries has increased continuously over recent years. The issue at stake is if this rise includes healthy years. The answer depends on the health indicator used, e.g., perceived health, disability, or cognitive impairment. A study by Jagger et al. (2016) provides evidence for an increase in life expectancy without cognitive impairment and an absolute compression of cognitive impairment between 1991 and 2011. Information on life expectancy without cognitive impairment is not yet available for the Netherlands. Similar to England, Dutch trends in life expectancy in excellent or good self-perceived health and in life expectancy without severe disability are favourable, although less pronouncedly so. Dutch and English data suggest that the additional years lived by the population are at least partly spent in good health.

The effect of trends in health and longevity on health services use by older adults

Background

The effect of population aging on future health services use depends on the relationship between longevity gains and health. Whether further gains in life expectancy will be paired by improvements in health is uncertain. We therefore analyze the effect of population ageing on health services use under different health scenarios. We focus on the possibly diverging trends between different dimensions of health and their effect on health services use.

Methods

Using longitudinal data on health and health services use, a latent Markov model has been estimated that includes different dimensions of health. We use this model to perform a simulation study and analyze the health dynamics that drive the effect of population aging. We simulate three health scenarios on the relationship between longevity and health (expansion of morbidity, compression of morbidity, and the dynamic equilibrium scenario). We use the scenarios to predict costs of health services use in the Netherlands between 2010 and 2050.

Results

Hospital use is predicted to decline after 2040, whereas long-term care will continue to rise up to 2050. Considerable differences in expenditure growth rates between scenarios with the same life expectancy but different trends in health are found. Compression of morbidity generally leads to the lowest growth. The effect of additional life expectancy gains within the same health scenario is relatively small for hospital care, but considerable for long-term care.

Conclusions

By comparing different health scenarios resulting in the same life expectancy, we show that health improvements do contain costs when they decrease morbidity but not mortality. This suggests that investing in healthy aging can contribute to containing health expenditure growth.

Benefits for elders with vulnerable health from the Chronic Disease Self-management Program (CDSMP) at short and longer term

Background

When health declines, older persons may benefit from an intervention program that strengthens their self-management and empowers them to keep in control of their own body and life. Therefore we conducted a Randomized Controlled Trial using the Chronic Disease Self-Management Program (CDSMP) in a sample of 169 older persons in frail health and in need of elderly care.

Methods

We assessed psychological coping resources and wellbeing, pre- and posttreatment and at 6-month follow-up, and investigated whether specific subgroups would benefit in particular from the intervention.

Results

The CDSMP appeared effective with respect to sense of mastery but only in the lower educated participants (p < .05). Furthermore, the intervention stabilized valuation of life in participants, whereas in the controls valuation of life decreased. The high appreciation score and low drop-out are indicative for the applicability of the CDSMP for this specific target group.

Conclusions

We recommend integration of the ingredients of the program into the daily healthcare practice of professionals working with vulnerable older persons. This would involve professional guidance starting from interpersonal equality and emphasising a persons possibilities given their physical or cognitive limitations. This will help older vulnerable persons to focus on their own attainable goals and to experience being successful.

Trial registration

The trial was registered in the Dutch Trial Register as NTR 1173 at 08-03-2008; ‘Is selfmanagement benefical for well-being of average older persons?’ http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=1173

Noninvasive molecular screening for oral precancer in Fanconi anemia patients

LOH at chromosome arms 3p, 9p, 11q, and 17p are well-established oncogenetic aberrations in oral precancerous lesions and promising biomarkers to monitor the development of oral cancer. Noninvasive LOH screening of brushed oral cells is a preferable method for precancer detection in patients at increased risk for head and neck squamous cell carcinoma (HNSCC), such as patients with Fanconi anemia. We determined the prevalence of LOH in brushed samples of the oral epithelium of 141 patients with Fanconi anemia and 144 aged subjects, and studied the association between LOH and HNSCC. LOH was present in 14 (9.9%) nontransplanted patients with Fanconi anemia, whereas LOH was not detected in a low-risk group (n = 50, >58 years, nonsmoking/nonalcohol history) and a group with somewhat increased HNSCC risk (n = 94, >58 years, heavy smoking/excessive alcohol use); Fisher exact test, P = 0.023 and P = 0.001, respectively. Most frequent genetic alteration was LOH at 9p. Age was a significant predictor of LOH (OR, 1.13, P = 0.001). Five patients with Fanconi anemia developed HNSCC during the study at a median age of 39.6 years (range, 24.8-53.7). LOH was significantly associated with HNSCC (Fisher exact test, P = 0.000). Unexpectedly, the LOH assay could not be used for transplanted patients with Fanconi anemia because donor DNA in brushed oral epithelium, most likely from donor leukocytes present in the oral cavity, disturbed the analysis. Noninvasive screening using a LOH assay on brushed samples of the oral epithelium has a promising outlook in patients with Fanconi anemia. However, assays need to be adapted in case of stem cell transplantation, because of contaminating donor DNA.

Association of Cardiometabolic Multimorbidity With Mortality

IMPORTANCE

The prevalence of cardiometabolic multimorbidity is increasing.

OBJECTIVE

To estimate reductions in life expectancy associated with cardiometabolic multimorbidity.

DESIGN, SETTING, AND PARTICIPANTS

Age- and sex-adjusted mortality rates and hazard ratios (HRs) were calculated using individual participant data from the Emerging Risk Factors Collaboration (689,300 participants; 91 cohorts; years of baseline surveys: 1960-2007; latest mortality follow-up: April 2013; 128,843 deaths). The HRs from the Emerging Risk Factors Collaboration were compared with those from the UK Biobank (499,808 participants; years of baseline surveys: 2006-2010; latest mortality follow-up: November 2013; 7995 deaths). Cumulative survival was estimated by applying calculated age-specific HRs for mortality to contemporary US age-specific death rates.

EXPOSURES

A history of 2 or more of the following: diabetes mellitus, stroke, myocardial infarction (MI).

MAIN OUTCOMES AND MEASURES

All-cause mortality and estimated reductions in life expectancy.

RESULTS

In participants in the Emerging Risk Factors Collaboration without a history of diabetes, stroke, or MI at baseline (reference group), the all-cause mortality rate adjusted to the age of 60 years was 6.8 per 1000 person-years. Mortality rates per 1000 person-years were 15.6 in participants with a history of diabetes, 16.1 in those with stroke, 16.8 in those with MI, 32.0 in those with both diabetes and MI, 32.5 in those with both diabetes and stroke, 32.8 in those with both stroke and MI, and 59.5 in those with diabetes, stroke, and MI. Compared with the reference group, the HRs for all-cause mortality were 1.9 (95% CI, 1.8-2.0) in participants with a history of diabetes, 2.1 (95% CI, 2.0-2.2) in those with stroke, 2.0 (95% CI, 1.9-2.2) in those with MI, 3.7 (95% CI, 3.3-4.1) in those with both diabetes and MI, 3.8 (95% CI, 3.5-4.2) in those with both diabetes and stroke, 3.5 (95% CI, 3.1-4.0) in those with both stroke and MI, and 6.9 (95% CI, 5.7-8.3) in those with diabetes, stroke, and MI. The HRs from the Emerging Risk Factors Collaboration were similar to those from the more recently recruited UK Biobank. The HRs were little changed after further adjustment for markers of established intermediate pathways (eg, levels of lipids and blood pressure) and lifestyle factors (eg, smoking, diet). At the age of 60 years, a history of any 2 of these conditions was associated with 12 years of reduced life expectancy and a history of all 3 of these conditions was associated with 15 years of reduced life expectancy.

CONCLUSIONS AND RELEVANCE

Mortality associated with a history of diabetes, stroke, or MI was similar for each condition. Because any combination of these conditions was associated with multiplicative mortality risk, life expectancy was substantially lower in people with multimorbidity.

A 13-year prospective cohort study on the effects of aging and frailty on the depression-pain relationship in older adults

OBJECTIVES

The primary aim of the study is to investigate the effect of age and aging on the association between pain and depression over 13 years. We hypothesized that (1) this association would become stronger with age and frailty and that (2) this association is mainly driven by somatic and psychological factors.

METHODS

Data were derived from the Longitudinal Aging Study Amsterdam, a prospective population-based cohort study with four follow-up measurements over 13 years, consisting of 1528 respondents (mean age 67.9 ± 8.1). Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale; pain was measured with an adapted version of the Nottingham Health Profile. Follow-up time and age were used as proxy variables for aging and gait speed as frailty marker. Cognition, mastery and neuroticism were measured using the mini mental state examination, the Pearlin Mastery Scale and the Dutch Personality Questionnaire respectively.

RESULTS

Linear mixed models showed that pain and depressive symptoms were associated over the 13-year follow-up: b = 0.095, p < 0.001. Neither aging nor frailty changed this association. Measured somatic and psychological characteristics explained 40% of the covariance between pain and depressive symptoms over time.

DISCUSSION

When dealing with people suffering from pain and depression, interventions should be similar for all aged people, encompassing both somatic and psychological factors, irrespective of age or frailty status.

Do negative life events promote gerotranscendence in the second half of life?

OBJECTIVES

Gerotranscendence has been defined as a developmental shift in meta-perspective from a materialistic and pragmatic view to a more cosmic and transcendent view. Although gerotranscendence has been argued to increase with age and life experiences, the results have been mixed and based on cross-sectional studies. We use a longitudinal setting to investigate the role of negative life events, age, and gender on change in one dimension of gerotranscendence, cosmic transcendence.

METHOD

1569 individuals (ages 58-89) answered a questionnaire on cosmic transcendence in two cycles of the Longitudinal Aging Study Amsterdam in 1995-1996 (time 1) and 1998-1999 (time 2). Controlling for education, marital status, religious affiliation, chronic diseases, functional limitations, depressive symptoms, and social support, change models based on structural equation modeling were fitted to the data to test whether negative life events, age, and gender were associated with change in cosmic transcendence.

RESULTS

A higher number of negative life events, especially negative life events other than deaths of others, were associated with increased cosmic transcendence, whereas experiencing no negative life events was associated with decreased cosmic transcendence. The level of cosmic dimension was higher at older than younger ages. Cosmic transcendence decreased over time among the older participants and women, whereas it increased among the younger participants and men.

CONCLUSION

Experiencing negative life events has the potential to promote the development of cosmic transcendence, even when controlling for age and gender. In the absence of negative life events, however, cosmic transcendence was observed to decline with aging.

The relationships between ADHD and social functioning and participation in older adults in a population-based study

OBJECTIVE

To examine the associations between ADHD and social functioning and participation among older adults.

METHOD

Data were used from the Longitudinal Aging Study Amsterdam (LASA). In 2008/2009, respondents were asked about social functioning and participation. A diagnostic interview to diagnose ADHD was administered among a subsample (N = 231, age 60-94 years). ADHD diagnosis and level of ADHD symptoms were assessed.

RESULTS

ADHD diagnosis was associated with being divorced/never married, having less family members in their network, and emotional loneliness. Level of ADHD symptoms was associated with more emotional support given, emotional and social loneliness, greater recreational social participation, and lower income level.

CONCLUSION

ADHD in old age is related to being divorced/never married and loneliness but not to work participation. Psycho geriatric practices should direct their attention to loneliness when treating ADHD.

Prevalence and incidence of memory complaints in employed compared to non-employed aged 55-64 years and the role of employment characteristics

Objectives

To examine the association of employment status and characteristics with prevalent and incident memory complaints (MC) in 55–64-year-olds.

Methods

Subjects were participants of the Longitudinal Aging Study Amsterdam (LASA). Respondents with baseline data were selected to examine the association of employment status (n = 1525) and employment characteristics (n = 1071) with prevalent MC (i.e., MC at baseline). Respondents without MC at baseline were selected to examine the association of employment (n = 526) and employment characteristics (n = 379; working hours, job prestige, job level, psychological job demands, iso-strain) with incident MC (i.e., no MC at baseline and MC at three-year follow-up). Associations were adjusted for relevant covariates (demographics, memory performance, physical health, mental health, personality traits). Logistic regression was applied. Data were weighed according to gender and age of the Dutch population.

Results

At baseline 20.5% reported MC. At three-year follow-up, 15.4% had incident MC. No associations were found between employment status and MC. Adjusted analysis revealed that individuals with high occupational cognitive demands were more likely to have prevalent MC.

Conclusions

Middle-aged workers are equally as likely to experience MC as non-working age-peers. Among workers, those with cognitively demanding work were more likely to experience MC, independent of memory performance. Memory decline due to ageing may be noticed sooner in 55–64-year-olds performing cognitively demanding work.
