Prevalence of cancer-related cognitive impairment among patients with nasopharyngeal carcinoma: a cross-sectional study

OBJECTIVE

To examine the prevalence of cancer-related cognitive impairment (CRCI) and its contributing factors in patients with nasopharyngeal carcinoma (NPC) and explore the relationship between various assessment methods.

METHODS

A cross-sectional study was conducted with 367 patients with NPC between March 2022 and April 2024 at Chongqing University Cancer Hospital. The data gathered from the demographic questionnaire, Montreal Cognitive Assessment (MoCA), Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) were analyzed using logistic regression.

RESULTS

Out of 367 participants, males accounted for 271 (73.84%). There were 217 (59.13%) individuals aged between 35-55 years. Cognitive impairment incidence was 58.04% using MoCA and 47.98% using FACT-Cog. Years of education, work condition, age and time since diagnosis (≥ 11 months) were all significantly associated with cognitive impairment using MoCA, the strongest being time since diagnosis (≥ 11 months) (OR = 2.672, 95% CI = 1.191-5.997, P = 0.017). Gender, marital status (married), place of residence (township), place of residence (city), alcohol history, SAS and SDS were all significantly associated with FACT-Cog, the strongest being marital status (married) (OR = 4.100, 95% CI = 1.130-14.87, P = 0.032).

CONCLUSION

Patients diagnosed with NPC exhibit susceptibility to CRCI. There was a weak correlation between some aspects of the subjective tests and the objective test scores. Advanced age and disease diagnosis longer than 10 months are associated with a heightened risk of objective cognitive impairment. Furthermore, residing in rural areas, female, married, alcohol history, SAS and SDS increases the likelihood of subjective cognitive impairment. These findings highlight the need to select appropriate assessment scales for different needs and take targeted interventions to address CRCI in patients with NPC.

Effect of a juggling-based physical activity on postural stability, reaction time, and attention focus in older adults: a randomized crossover study

BACKGROUND

In the aging society, more attention is paid to the promotion of forms of physical activity that can improve postural stability and cognitive functioning. In this context, the importance of combined exercises, requiring simultaneous physical and cognitive involvement, is emphasized. Juggling seems to be a form of activity that is both cognitively and physically demanding. The purpose of this study was to determine the effect of additional juggling exercise on postural stability and cognitive abilities in healthy, physically active older adults.

METHODS

Twenty-six healthy and physically active older adults (70.08±4.40 years old) were included in a randomized crossover study. The addition of juggling three times a week during four weeks was the main intervention (one period), while the control phase included four weeks with no addition of juggling (second period). Measurements of postural stability and cognitive abilities were performed before and after each period. For the purpose of postural stability assessment, a velocity of center of pressure with root mean square, area 95 percentile, medio-lateral and anterior-posterior range of motion were measured. Center of pressure signals were obtained using an AccuGait™ System force plate in three conditions: free standing, dual-task and limits of stability. The Vienna Test System was used for the assessment of selected cognitive abilities. A battery of reaction time tests and Cognitrone test were used for this purpose.

RESULTS

A significant interaction effect of intervention and time was observed in the postural stability dual-task condition in the root mean square of the center of pressure velocity in the advantage of the juggling period (medio-lateral: F=14.83, p<.01, ƞp2=.37; anterior-posterior: F=26.30, p<.01, ƞp2=.51). Additionally, moderate effect sizes were observed in the velocity of the center of pressure and variability of simple reaction time measurements, but without statistical significance.

CONCLUSIONS

The results of this study indicate that the implementation of juggling activity in everyday life may have positive effects on cognitive abilities and postural stability in healthy, physically active older adults, but the true effect may be low to moderate.

TRIAL REGISTRATION

The study was registered retrospectively (30.10.2023) at ClinicalTrials.gov (NCT06108713).

Well-designed manufacturing work improves some cognitive abilities in individuals with cognitive impairments

Introduction

Employment is recognized as a fundamental human right, which correlates with better physical and mental health. Importantly, well-designed work, which considers the physical, social, and psychological impacts of work, can serve to enhance the cognitive abilities of workers. Although often overlooked, work for individuals with disabilities, including cognitive impairments, is equally important for their physical and mental well-being. What has not been established, however, is whether well-designed work can also enhance the cognitive abilities of individuals with cognitive impairments.

Methods

Using a longitudinal study design, we investigated the impact of well-designed work on the cognitive abilities of 60 participants (operators) at the AMIPI Foundation factories, which employ individuals with cognitive impairments to produce electrical cables and harnesses for the automobile industry. The same operators were assessed at three different time points: upon hiring (n = 60), and after working in the factory for 1 year (n = 41, since 19 left the factory) and 2 years (n = 28, since 13 more left the factory). We used five cognitive tests evaluating: (1) finger and manual dexterity, bimanual dexterity, and procedural memory using the Purdue Pegboard; (2) sustained and selective attention using the Symbol Cancellation Task; (3) short- and long-term declarative verbal memory and long-term verbal recognition memory using Rey's Audio-Verbal Learning Test; (4) short- and long-term visual recognition memory using the Continuous Visual Memory Test; and (5) abstract reasoning using Raven's Standard Progressive Matrices.

Results

We observed improvements in procedural memory, sustained and selective attention, and short- and long-term visual recognition memory after working in the factory for 1 or 2 years. We did not observe improvements in finger or manual dexterity or bimanual dexterity, nor short- or long-term declarative verbal memory or verbal recognition memory, nor abstract reasoning.

Discussion

We conclude that, in addition to improving physical and mental well-being, well-designed manufacturing work can serve as a training intervention improving some types of cognitive functioning in individuals with cognitive impairments.

The effects of work on cognitive functions: a systematic review

Introduction

Cognitive functions play a crucial role in individual's life since they represent the mental abilities necessary to perform any activity. During working life, having healthy cognitive functioning is essential for the proper performance of work, but it is especially crucial for preserving cognitive abilities and thus ensuring healthy cognitive aging after retirement. The aim of this paper was to systematically review the scientific literature related to the effects of work on cognitive functions to assess which work-related factors most adversely affect them.

Method

We queried the PubMed and Scopus electronic databases, in February 2023, according to the PRISMA guidelines (PROSPERO ID number = CRD42023439172), and articles were included if they met all the inclusion criteria and survived a quality assessment. From an initial pool of 61,781 papers, we retained a final sample of 64 articles, which were divided into 5 categories based on work-related factors: shift work (n = 39), sedentary work (n = 7), occupational stress (n = 12), prolonged working hours (n = 3), and expertise (n = 3).

Results

The results showed that shift work, occupational stress, and, probably, prolonged working hours have detrimental effects on cognitive functioning; instead, results related to sedentary work and expertise on cognitive functions are inconclusive and extremely miscellaneous.

Discussion

Therefore, workplace health and well-being promotion should consider reducing or rescheduling night shift, the creation of less demanding and more resourceful work environments and the use of micro-breaks to preserve workers' cognitive functioning both before and after retirement.

Exploring workability in an older working population: associations with cognitive functioning, sleep quality, and technostress

Objective

This observational study investigates workability and its associations with cognitive functioning, sleep quality and technostress among an older working population, also shedding light on potential differences between two occupational categories with different work schedules.

Methods

Workers aged over 50, employed in different working sectors (banking/finance, chemical and metal-mechanic industry) were administered a self- report questionnaire including Work Ability Index (WAI), cognitive tests (Stroop Color Task, Corsi Blocks, Digit Span), sleep quality questionnaires (Pittsburgh Sleep Quality Index-PSQI; Insomnia Severity Index-ISI; Ford Insomnia Response to Stress Test-FIRST) and technostress scale. Linear regression models evaluated associations among variables, interaction effects investigated potential moderators.

Results

A total of 468 aged workers categorized as white (WCWs; N = 289, 62%) or blue collars (BCWs; N = 179, 38%) were enrolled; most BCWs (N = 104; 58%) were night shift workers. WCWs reported higher workability, cognitive functioning, sleep quality and lower technostress (except for invasion and privacy subscales) than BCWs. Associations between cognitive functioning and workability were statistically significant only for BCWs [slopes equal to 0.2 (0.33), 0.8 (0.34), -0.02 (0.001) for Memory Span Corsi, Block Span Digit and Interference Speed respectively]; additionally, sleep quality significantly moderated this association (p = 0.007). Higher levels of technostress were associated with lower workability, and this relationship was stronger for BCWs.

Conclusion

The aging of the workforce has important implications for occupational health and safety. Our findings suggest potential interventions and protective measures to promote older workers' wellbeing; blue-collar workers particularly should benefit from tailored intervention to sustain workability and prevent technostress, considering the role of healthy sleep habits promotion.

Disparities in the Quality of Working Life Among Older Workers: Housing Conditions and Life Satisfaction With Latent Class Analysis

Little empirical research informs understanding of the disparate active aging experiences among working older adults, especially in terms of the association with living circumstances and life satisfaction. To address this knowledge gap, this study used latent class analysis on data from the 2020 Health and Retirement Study (HRS) core interview and focused on 1,194 employed adults aged 50 and above. The results revealed four subtypes of the quality of working life in older workers. Notably, in contrast to the other identified classes, higher levels of housing satisfaction and feelings of neighborhood safety were significantly associated with an increased likelihood of being a member of the group of older adults with the highest work capacities and the healthy work-life balance. Furthermore, participation in the class characterized by the highest work capacity and a healthy work-life balance was related to the highest levels of overall life satisfaction.

General cognitive ability in high school, attained education, occupational complexity, and dementia risk

INTRODUCTION

We address the extent to which adolescent cognition predicts dementia risk in later life, mediated by educational attainment and occupational complexity.

METHODS

Using data from Project Talent Aging Study (PTAS), we fitted two structural equation models to test whether adolescent cognition predicts cognitive impairment (CI) and Ascertain Dementia 8 (AD8) status simultaneously (NCognitive Assessment = 2477) and AD8 alone (NQuestionnaire = 6491) 60 years later, mediated by education and occupational complexity. Co-twin control analysis examined 82 discordant pairs for CI/AD8.

RESULTS

Education partially mediated the effect of adolescent cognition on CI in the cognitive assessment aample and AD8 in the questionnaire sample (Ps < 0.001). Within twin pairs, differences in adolescent cognition were small, but intrapair differences in education predicted CI status.

DISCUSSION

Adolescent cognition predicted dementia risk 60 years later, partially mediated through education. Educational attainment, but not occupational complexity, contributes to CI risk beyond its role as a mediator of adolescent cognition, further supported by the co-twin analyses.

HIGHLIGHTS

Project Talent Aging Study follows enrollees from high school for nearly 60 years. General cognitive ability in high school predicts later-life cognitive impairment. Low education is a risk partially due to its association with cognitive ability.

Changes in memory and attention during and after occupational rehabilitation: A longitudinal study

BACKGROUND

There is need for more knowledge about the relationship between work and cognitive functioning in sick-listed individuals.

OBJECTIVE

This study investigated whether the degree of work participation is relevant for recovery of cognitive functioning in sick-listed individuals.

METHODS

177 occupational rehabilitation participants and 70 controls participated in a non-randomised, longitudinal study. Participants completed computerised cognitive tests targeting sustained attention and working memory at start and end of rehabilitation and 3 and 12 months after rehabilitation. The change score performance in attention and memory between start and end, start and 3 months and 12 months was compared in individuals on sick leave 100-75%, 74-40% and 39-0% (three sick leave groups) of the time in the year after rehabilitation, and a control group not being on sick leave. Fixed effect analysis of covariance adjusting for education and work ability was used.

RESULTS

The sick leave group 100-75% had significantly lower score on work ability compared to the other groups at baseline. The main findings indicated that the sick leave group 39-0% improved significantly more in sustained attention compared to the sick leave group 100-75% between start and end of rehabilitation and from start of rehabilitation to 3 and 12 months after.

CONCLUSION

The degree of work participation seems relevant to recovery of the cognitive function sustained attention in sick-listed individuals. These findings encourage work rehabilitation clinicians, work consultants and employers to develop RTW plans which take into account that graded employment influence cognitive functioning.

Longitudinal associations between social relationships and cognitive function among Chinese older adults: The mediating role of healthy lifestyles

BACKGROUND

We aimed to explore whether social relationships and cognitive function were reciprocally related and whether healthy lifestyles mediate their association.

METHODS

This study included 3372 Chinese adults from the years 2014-2018 wave of the Chinese Longitudinal Healthy Longevity Survey.

RESULTS

Baseline social relationships were negatively associated with a change in cognitive function (β = -0.030, p = 0.043). Participants with a 1 standard deviation (SD) increase in social relationships had an approximately 6% reduced risk of developing cognitive impairment. However, baseline cognitive function did not independently predict social relationships. The association between △social relationships and △cognitive function was partially mediated by △a healthy lifestyle (B = 0.025, 95% CI = 0.013-0.041).

CONCLUSIONS

The association between social relationships and cognitive function may be unidirectional. Policies that promote cognitive function based on social relationships would benefit by taking into account lifestyle factors.

Successful ageing at work: The role of job characteristics in growth trajectories of work ability and motivation to work amongst older workers

In order to age successfully at work, people need to maintain or improve their work ability and motivation to work. This implies a process that develops over time and can differ substantially between individuals. This study investigated whether different trajectories of perceived work ability and motivation to work can be distinguished between older employees over time and to what extent job demands and job resources are predictive of these different trajectories. We applied growth mixture modelling amongst 5799 employees of 45 years and older at four time points. We found five distinct groups of older workers that differed in their trajectories of perceived work ability and four types of groups of older workers that differed in their trajectories of their motivation to work. Higher levels of physical demands, mental demands, autonomy, supervisor support, and colleague support were less common in unfavourable trajectories. This study gives Human Resource Management practitioners insight into how jobs should be designed to stimulate successful ageing at work.

Do supportive work environments matter for minority aging? Work stress and subjective cognitive impairment among middle-age and older lesbian, gay, bisexual, transgender, and queer adults

Research has documented how people's experiences at work affect their cognitive health outcomes, but how these processes unfold for minority groups, particularly lesbian, gay, bisexual, transgender, and queer (LGBTQ+) populations, is unclear. This study builds on the nascent literature by employing generalized structural equation models to test how experiencing major problems at work and working with LGBTQ+ supportive coworkers affect subjective cognitive impairment among middle-age and older LGBTQ+ adults. We also test for mediated and indirect effects of support and problems at work operating via vascular disease, sleep problems, and depression symptoms. Experiencing major problems at work is associated with a higher likelihood of reporting cognitive symptoms consistent with mild cognitive impairment, but this relationship is mediated by depression symptoms and sleep problems. Having LGBTQ+ supportive coworkers does not have direct effects on mild cognitive impairment, but does operate indirectly by decreasing problems at work and, in turn, decreases the likelihood of reporting cognitive symptoms consistent with mild cognitive impairment. Overall, we find that workplace stressors contribute to cognitive health directly and through mediated and indirect pathways and that supportive contexts reduce exposure to problems at work. We conclude with suggested possibilities to reorganize workplaces to improve long-term cognitive health outcomes for older adults, especially those who are LGBTQ+-identified.

Cognitive challenge as a probe to expose sex- and age-related differences during static contractions

Despite activities of daily living being frequently performed simultaneously with a cognitive task, motor function is often investigated in isolation, which can hinder the applicability of findings. This brief review presents evidence that 1) performing a cognitive challenge simultaneously with a motor task can negatively impact force steadiness and fatigability of limb muscles during a static contraction, 2) the negative impact on old adults (>65 years old), particularly older women is greater than young when a cognitive challenge is simultaneously performed with a static motor task, 3) age-related mechanisms potentially explain impairments in motor performance in the presence of a cognitive challenge, and 4) the mechanisms for the age-related decrements in motor performance can be distinct between men and women. These observations are highly relevant to the older adults, given the increased risk of accidents and injury when a motor task is performed with a high cognitive-demand task, especially in light of the expanding reliance on an aging workforce.

Aging and Burnout for Nurses in an Acute Care Setting: The First Wave of COVID-19

We examined the relationship between age, coping, and burnout during the peak of the COVID-19 pandemic with nurses in Texas (N = 376). Nurses were recruited through a professional association and snowball sampling methodology for the cross-sectional survey study. Framed in lifespan development theories, we expected that nurse age and experience would be positively correlated with positive coping strategies (e.g., getting emotional support from others) and negatively correlated with negative coping strategies (e.g., drinking and drug use). We also expected age to be negatively related to the emotional exhaustion and depersonalization facets of burnout and positively related to the personal accomplishment facet of burnout. Findings were largely supported in that age was positively associated with positive coping and personal accomplishment and age and experience were negatively correlated with negative coping and depersonalization. Age was not, however, associated with emotional exhaustion. Mediation models further suggest that coping explains some of the effect of age on burnout. A theoretical extension of lifespan development models into an extreme environment and practical implications for coping in these environments are discussed.

Executive Function Deficits and Borderline Personality Disorder Symptomatology in a Nonclinical Adult Sample: A Latent Variable Analysis

While borderline personality disorder (BPD) symptomatology has been studied extensively in clinical populations, the mechanisms underlying its manifestation in nonclinical populations remain largely understudied. One aspect of BPD symptomatology in nonclinical populations that has not been well studied is cognitive mechanisms, especially in relation to executive functions. To explore the cognitive mechanisms underlying BPD symptomatology in nonclinical populations, we analysed a large-scale dataset of 233 young adults that were administered with nine executive function tasks and BPD symptomatology assessments. Our structural equation modelling did not find any significant relations between latent factors of executive functions and the severity of BPD symptomatology. Contrary to our hypothesis, our result suggests that deficits in executive functions were not a risk factor for BPD symptomatology in the nonclinical young adult sample.

Job demands may determine cognitive and physical aging after retirement

During adulthood, we spend most of our time and efforts at work. However, the impact of employment in aging is poorly explored. Our study addressed how job demands can affect aging after retirement. We have developed a descriptive observational study carried out in 367 older adults with a mean age of 73.9 years (66.5% women and 33.5% men), measuring cognition and functional status. Our results demonstrate that older adults who had high mental demands in their jobs, show better scores in cognition. However, they show poor functional development of basic and instrumental activities of daily life (p< .05). In contrast, former workers who had high physical demands, display lower scores in cognition and lower functional performance in instrumental activities (p< .05). Work life activities contribute to cognitive and physical decline after retirement. Therefore, healthy aging should include interventions that consider the job influence on the age impairment.

Effects of Virtual Reality Rehabilitation Training on Cognitive Function and Activities of Daily Living of Patients With Poststroke Cognitive Impairment: A Systematic Review and Meta-Analysis

OBJECTIVE

To determine the effects of virtual reality (VR) rehabilitation training on the cognitive function and activities of daily living (ADL) of patients with poststroke cognitive impairment (PSCI).

DATA SOURCES

Four Chinese databases and 6 English databases were systematically searched for studies published until August 31, 2021, by using Medical Subject Headings of the National Library of Medicine terms such as virtual reality, cognition disorders, cognitive dysfunction, and stroke and free terms such as virtual environment, VR, cognition impairment, cerebrovascular accident, and PSCI.

STUDY SELECTION

Randomized controlled trials treating PSCI with VR training were included. The control groups received conventional treatments such as conventional rehabilitation training and drug therapy; the experimental groups received VR rehabilitation training. The outcome measures were cognitive function and ADL.

DATA EXTRACTION

Two researchers independently extracted key information from eligible studies. The methodological quality of the studies was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions v5.1.0. Meta-analysis was performed using RevMan v5.4. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines.

DATA SYNTHESIS

Twenty-one studies (1149 participants) were included. Meta-analyses found that compared with the control group, VR rehabilitation training increased Mini-Mental State Examination, Montreal Cognitive Assessment, Loewenstein Occupational Therapy Cognitive Assessment, Rivermead Behavioral Memory Test Second Edition, Barthel Index, Modified Barthel Index, and FIM scores; event-related potential 300 (P300) amplitude; and the N-acetylaspartate/creatinine (Cr) ratio on proton magnetic resonance spectroscopy (1H-MRS) and reduced P300 latency; Trail Making Test scores; and the choline-containing compounds/Cr ratio on 1H-MRS (all P<.05). These results indicated that VR training improved cognitive function and ADL in PSCI.

CONCLUSIONS

VR rehabilitation training promotes the rehabilitation of cognitive function and recovery of ADL in patients with PSCI and may be a good complementary approach to conventional cognitive interventions.

Online assessment of cognitive functioning across the adult lifespan using the eCOGTEL: a reliable alternative to laboratory testing

As the population ages, risks for cognitive decline threaten independence and quality of life of older adults. Classically, psychological assessment tools that evaluate cognitive functioning are administered in face-to-face laboratory sessions, which are time- and resource-consuming. The present study set out to examine whether the eCOGTEL—an online adaptation of the Cognitive Telephone Screening Instrument (COGTEL; Kliegel et al. in J Psychol 141(2):147–170, 2007)—represents a reliable measure of cognitive performance in adulthood. Therefore, an age-stratified adult lifespan sample of 253 participants (aged 19–86 years) completed a face-to-face assessment in the laboratory and a self-administered online version, at their homes. A second, independent sample of 176 younger adults (aged 19–30 years) performed a test–retest assessment of the eCOGTEL. Results showed strong correlations between overall cognitive scores assessed online and in the laboratory, as well as a high test–retest reliability. Further, comparable data distributions between both assessment modes underline the feasibility of the eCOGTEL across the adult lifespan and particularly in older age. Our findings thereby indicate that the eCOGTEL can reliably measure cognitive performance across the lifespan at reduced costs, which may help detecting individuals at risk of developing age-related cognitive decline. Due to these strengths, the eCOGTEL represents a valuable contemporary approach for the resource-efficient online assessment of cognition, which may benefit a broad array of fundamental and applied research fields, such as clinical and organizational psychology.

Sustained Attention and Working Memory Predict the Number of Days on Health-Related Benefits in the Year Following Occupational Rehabilitation

Purpose The objective of this study was to investigate the association between cognitive and emotional functioning and the number of days on health-related benefits such as sick leave, work assessment allowance and disability pension. We investigated whether cognitive and emotional functioning at the start of rehabilitation and the change from the start to the end of rehabilitation predicted the number of days on health-related benefits in the year after occupational rehabilitation. Methods A sample of 317 individuals (age 19-67 years), mainly diagnosed with a musculoskeletal or mental and behavioural ICD-10 disorder, participated. The sample was stratified depending on the benefit status in the year before rehabilitation. Those receiving health-related benefits for the full year comprised the work assessment allowance and disability pension (WAA) group and those receiving benefits for less than a year comprised the sick leave (SL) group. The participants were administered cognitive and emotional computerised tests and work and health questionnaires at the beginning and end of rehabilitation. The cumulative number of days on health-related benefits during 12 months after rehabilitation was the primary outcome variable and age, gender, educational level, subjective health complaints, anxiety, and depression were controlled for in multiple regression analyses. Results The WAA group (n = 179) was significantly impaired at baseline compared to the SL group (n = 135) in focused attention and executive function, and they also scored worse on work and health related variables. Higher baseline scores and change scores from the start to the end of rehabilitation, for sustained attention, were associated with fewer number of health-related benefit days in the WAA group, while higher baseline scores for working memory were associated with fewer number of health-related benefit days in the SL group. Conclusions New knowledge about attention and memory and return to work in individuals with different benefit status may pave the way for more targeted programme interventions. Rehabilitation programmes could benefit from designing interventions that respectively improve sustain attention and working memory related to working life in individuals on sick leave or work assessment allowance and disability pension.

Job Strain and Trajectories of Cognitive Change Before and After Retirement

OBJECTIVES

We examined associations between job strain and trajectories of change in cognitive functioning (general cognitive ability plus verbal, spatial, memory, and speed domains) before and after retirement.

METHODS

Data on indicators of job strain, retirement age, and cognitive factors were available from 307 members of the Swedish Adoption/Twin Study of Aging. Participants were followed up for up to 27 years (mean = 15.4, SD = 8.5).

RESULTS

In growth curve analyses controlling for age, sex, education, depressive symptoms, cardiovascular health, and twinness, greater job strain was associated with general cognitive ability (estimate = -1.33, p = .002), worse memory (estimate = -1.22, p = .007), speed (estimate = -1.11, p = .012), and spatial ability (estimate = -0.96, p = .043) at retirement. Greater job strain was also associated with less improvement in general cognitive ability before retirement and a somewhat slower decline after retirement. The sex-stratified analyses showed that the smaller gains of general cognitive ability before retirement (estimate = -1.09, p = .005) were only observed in women. Domain-specific analyses revealed that greater job strain was associated with less improvement in spatial (estimate = -1.35, p = .010) and verbal (estimate = -0.64, p = .047) ability before retirement in women and a slower decline in memory after retirement in women (estimate = 0.85, p = .008) and men (estimate = 1.12, p = .013). Neither preretirement nor postretirement speed was affected significantly by job strain.

DISCUSSION

Greater job strain may have a negative influence on overall cognitive functioning prior to and at retirement, while interrupting exposure to job strain (postretirement) may slow the rate of cognitive aging. Reducing the level of stress at work should be seen as a potential target for intervention to improve cognitive aging outcomes.

Effect of one-session focused attention meditation on the working memory capacity of meditation novices: A functional near-infrared spectroscopy study

INTRODUCTION

Previous studies have revealed that one-session focused attention meditation (FAM) can improve top-down attention control, which is one of the factors of working memory capacity (WMC). In addition, FAM shares various neural substrates, including the dorsolateral prefrontal cortex (DLPFC), with WMC. Thus, we hypothesized that one-session FAM would improve WMC by activating the DLPFC evoked by the top-down attention control. In this study, we examined whether FAM modified WMC in individuals with little to no meditation experience.

METHODS

The participants were randomly assigned to either the FAM group (N = 13) or the control group (N = 17) who engaged in random thinking (i.e., mind-wandering). Before and after each 15-min intervention, the participants' WMC was measured according to the total number of correct answers in the Reading Span Test. During each intervention, functional near-infrared spectroscopy was employed to measure the blood flow in the participants' DLPFC and determine the top-down attention control effect.

RESULTS

In the FAM group, WMC increased, and the bilateral DLPFC was activated during the intervention. As for the control group, WMC decreased after the intervention, and the bilateral DLPFC was not activated during the intervention. A correlation was also found among all participants between the increase in WMC and the activation of the bilateral DLPFC.

CONCLUSION

The study findings suggest that top-down attention control during FAM can activate the bilateral DLPFC and increase WMC among meditation novices.

Challenges arising for older workers from participating in a workplace intervention addressing work ability: a qualitative study from Germany

OBJECTIVE

Studies examining what renders workplace interventions to sustain and promote work ability of older workers successful have largely neglected older workers´ perspective. This paper outlines the results of a study with regard to older workers´ experiences and expectations of a workplace intervention. Based on these findings, some reflections on how to improve the design and the implementation of workplace interventions for older workers are provided.

METHODS

Semi-structured interviews were conducted with older workers (N = 8) participating in a workplace intervention undertaken at one production site of a large manufacturing company in Baden-Wurttemberg/Germany. The interview guide included questions on participants´ experiences with and expectations of the intervention. The interviews were recorded, transcribed verbatim and analyzed using qualitative content analysis according to Mayring (2014).

RESULTS

Older workers´ reported some challenges they face due to their participation in the workplace intervention. These resulted from the work environment (physical challenges), the work process design (new long work cycle), the work organization (tight time allowances, little job rotation, change of teams, age stereotypes) and the management of the workplace intervention (bad information, feeling of occupational insecurity and lack of being valued).

CONCLUSIONS

The study shows that challenges arising for older workers from their participation in the workplace intervention may have counteracted the promotion of work ability. As findings suggest, some of these challenges might have been avoided either by considering workers´ perspective during design and implementation of an intervention or by referring to evidence on aging and work ability.

Faculty Service-Learning Students as Home-Visitors: Outcomes of a Lifestyle Modification Program for Vulnerable Families With Residents in Rural Indonesian Communities

Background: Risks attributed to chronic diseases, cancer, musculoskeletal discomfort, and infectious diseases among Indonesians were found to be associated with lifestyle behaviors, particularly in rural areas. The aim of this study was to examine the outcomes of a home-visiting lifestyle modification program on improving health risk behaviors among Indonesians living in rural areas. Methods: A total of 160 Indonesians living in rural hamlets in the Yogyakarta Region of Indonesia participated in the program in the period of June 21 to July 21, 2019. In the pre-intervention home interview, learning needs of diet, exercise, hand hygiene, and substance use were identified by using structured assessment tools. In the next home visit, the visitors provided health education and facilitated lifestyle planning based on the related affective and cognitive domains of learning. Subsequent follow-up interviews were conducted 3 weeks after intervention. Results: The results showed that the self-reported intake of vegetables, fruits, meat and salt, cooking with less oil, hand hygiene before eating, number of cigarettes smoked, and symptoms of muscle stiffness significantly improved after the intervention. The lifestyle modification program consisted of the affective and cognitive domains of learning, and could lead to the target behavioral changes in self-reported and observable measures over 1 month. Conclusions: The findings contributed to the framework of community-based health education for health risk reduction and behavioral modification in developing rural communities where health care resources were limited. Further studies with control groups and vigorous objective measures were recommended to elucidate its long-term impacts. The factors leading to its sustainability concerning collaborative care partnerships between community residents and faculty resources are worthy of continued exploration.

Multifaceted Demands of Work and Their Associations with Cognitive Functioning: Findings From the Health and Retirement Study

OBJECTIVES

The present study examines the associations among mental, social, and physical demands of work with cognitive functioning among older adults in the United States.

METHODS

Data from 3,176 respondents in the Health and Retirement Study were analyzed using growth curve modeling (2004-2014). The study investigated differences by gender, race, ethnicity, and education.

RESULTS

Higher mental and social demands of work were associated with higher levels of initial cognitive functioning, but not significantly associated with slower cognitive decline over time. Physical demands of work were negatively associated with initial cognitive functioning and also marginally associated with a slower rate of decline in cognitive functioning going into older adulthood. In stratified analyses, results varied by sociodemographic characteristics.

DISCUSSION

The results partially support the environmental complexity hypothesis and the productive aging framework in that higher mental and social demands and lower physical demands relate to better cognitive functioning at baseline, with the differences appearing stable throughout older adulthood. The stratified results shed light on addressing disparities in cognitive aging and work environments.

The Relation Between Cognitively Measured Executive Functions and Reported Self-Regulated Learning Strategy Use in Adult Online Distance Education

While executive functions (EFs) and self-regulated learning (SRL) strategy use have been found to be related in several populations, this relationship has not been studied in adult online distance education (ODE). This is surprising as self-regulation, and thus using such strategies, is very important here. In this setting, we studied the relation between basic executive functions (i.e., working memory and shifting, measured with cognitive tests) and reported SRL-strategy use (i.e., management of time and effort, complex and simple cognitive strategy use, contacts with others, and academic thinking) within a correlational design with 889 adult online distance students. In this study, we performed regression analyses and took age and processing speed into consideration, as processing speed and EFs decrease with age, whereas self-regulation is reported to increase with age. Cognitively measured working memory was not related to reported SRL-strategy use in adult ODE students. Thus, even though the SRL-components within the strategies seem to elicit working memory, reported SRL-strategy use is not related to the functioning of this basic EF (measured with cognitive tests). This means that if SRL-strategy use needs to be increased in adult ODE students, training of working memory might not be an effective manner for achieving that goal. Better shifting and processing speed were related to less reported SRL-strategy use, which might suggest that SRL-strategies might be used to compensate for lower shifting (in academic thinking) and lower processing speed (in simple cognitive strategy use and contacts with others). With increasing age, the number of contacts with peers or teachers decreases. This latter finding might be of relevance during the pandemic since contacts with others is importance during lockdown.

The association between hypoparathyroidism and cognitive impairment: a systematic review

CONTEXT AND PURPOSE

Hypocalcemia and low parathyroid hormone levels have been commonly suggested as factors able to induce central nervous system disturbances. However, evidences on the occurrence of cognitive impairment are limited or underestimated. The aim of this review is, therefore, to systematically summarize the available evidence concerning the occurrence of cognitive impairment among subjects suffering from idiopathic or secondary hypoparathyroidism.

METHODS

A systematic selection of the available literature was performed by searching the online databases PubMed, Scopus and Web of Knowledge.

RESULTS

The present systematic review included sixteen case report articles and one cross-sectional controlled study. Case reports were the most representative literature sources and involved ten women and seven men. The presence of cognitive impairment was mostly discussed in association with idiopathic hypoparathyroidism (HPT); five articles described the occurrence of cognitive impairment following postsurgical HPT. The case-controlled study reported a significant presence of peculiar cognitive deficits (e.g. reduced inhibitory control, impairment in visuo-spatial functioning among, and psychomotor retardation) among HPT subjects compared to healthy controls, with serum total calcium and its product with phosphorus as independent predictors of neuropsychological dysfunctions.

CONCLUSION

Even though mostly based on single case reports, the presence of neuropsychological dysfunctions in the context of HPT appears to be a consistent core finding.

Gender-Based Pathways to Cognitive Aging in the Mexican-Origin Population in the United States: The Significance of Work and Family

OBJECTIVES

This study uses the life course perspective to explore the role of key midlife factors (occupation and number of children) for gender- and nativity-based pathways to cognitive aging for older Mexican Americans.

METHOD

Using the Hispanic Established Populations for the Epidemiologic Study of the Elderly (H-EPESE, 1993/1994-2016, n = 2,779), this study presents (a) cognitive impairment trajectories over 20 years of data and (b) multinomial logistic regression analyses of trajectory group membership by lifetime occupation and number of children, controlling for educational attainment.

RESULTS

For older Mexican American men, lifetime employment in agricultural occupations is associated with elevated risk for late-life cognitive impairment. Delayed risk for impairment is observed for U.S.-born men who were employed in factory work (e.g., production and repair) and in Mexican-born men who were employed in occupations with skilled or supervisory requirements. For all women, labor force participation, especially in skilled occupations, is related to a delayed risk of cognitive impairment. Number of children is unrelated to impairment for men; however, women with five or more children (compared to women with two to four children) are at risk for consistent and rapid cognitive impairment in late life.

DISCUSSION

Late-life cognitive health disparities that disproportionately impact the Mexican American population can be addressed by improving access to educational and occupational opportunities in early and midlife. This study points to key areas of intervention within work and the home for the Mexican-origin population.

Insights into the Sustainable Return to Work of Aging Workers with a Work Disability: An Interpretative Description Study

Purpose A sustainable return to work (S-RTW) following prolonged work disability poses particular challenges as workers age. This article provides a synthesis of the factors and issues involved in a S-RTW process for aging workers following such a disability. Methods Using interpretive description methods, a critical review was conducted of the literature specifying return-to-work factors and issues for aging workers with regard to four major causes of work disability (musculoskeletal disorders, common mental disorders, cancer or other chronic diseases). The initial review concerned the 2000-2016 literature, and was subsequently updated for November 2016-December 2018. To further explore and contextualise the results of this literature review, four focus groups were held with stakeholders, representing the workplace, insurance, and healthcare systems and workers. Qualitative thematic analysis was performed. Results Fifty-five articles were reviewed and 35 stakeholders participated in the focus groups. Returning to work and staying at work appear to be particularly challenging for aging workers, who face notable issues and stigma concerning their ability to meet work demands, as well as their mobilisation and engagement in these processes. Such findings echo in many ways the main assertions of the literature on aging at work, except those regarding the transformation of capacities with aging, which is not mentioned in relation to workers with a work disability. The influence of healthcare and compensation systems on the S-RTW of aging work-disabled workers has also received little attention to date. Conclusions The results underscore that aging workers with a disability are frequently vulnerable in terms of their health or their jobs. Intersectoral efforts are needed to remedy this situation to keep them at work.

Learning at work: a model of learning and development for younger workers

In rapidly changing work environments, individuals need a willingness and ability to learn new skills and knowledge to contribute to their organization's goals and their own employability. As the baby-boomer generation begins to exit the workplace, organizations need to pay attention to developing the capability of younger, novice workers who will increasingly comprise the core workforce of the future. The present study, grounded in social cognitive theory, develops and examines a model of learning and development for younger workers. In total, 1,732 employees in New Zealand aged 16–24 years completed a survey relating to their perceptions, beliefs, and intentions regarding learning and development. The results from structural equation modeling show that individual and work-environment factors both influence younger workers' developmental intentions but affect this through different pathways. The study contributes to a better understanding of the development process for younger workers and offers implications for management based on these findings.

Biological and environmental predictors of heterogeneity in neurocognitive ageing: Evidence from Betula and other longitudinal studies

Individual differences in cognitive performance increase with advancing age, reflecting marked cognitive changes in some individuals along with little or no change in others. Genetic and lifestyle factors are assumed to influence cognitive performance in ageing by affecting the magnitude and extent of age-related brain changes (i.e., brain maintenance or atrophy), as well as the ability to recruit compensatory processes. The purpose of this review is to present findings from the Betula study and other longitudinal studies, with a focus on clarifying the role of key biological and environmental factors assumed to underlie individual differences in brain and cognitive ageing. We discuss the vital importance of sampling, analytic methods, consideration of non-ignorable dropout, and related issues for valid conclusions on factors that influence healthy neurocognitive ageing.

Relationship Between Sedentary Behavior and Physical Activity at Work and Cognition and Mood

BACKGROUND

Sedentary behavior is negatively associated with cognition and mood. Adults often engage in high levels of sedentary behavior at work through sitting, which may impact productivity. Consequently, replacing sitting with standing and physical activity (PA) is recommended. However, the associations between sitting, standing, and PA at work and cognition and mood are unknown; this study, therefore, aimed to explore these relationships.

METHODS

A total of 75 healthy full-time workers (33 male, mean [SD]; 33.6 [10.4] y, 38 [7] work hr/wk) wore sedentary behavior (activPAL) and PA (SenseWear Pro) monitors for 7 days and recorded their work hours. The day after this monitoring period, participants completed cognitive tests (executive function, attention, and working memory) and mood questionnaires (affect, alert, content, and calm). Multiple linear regression analyses examined the associations between cognition and mood and the time spent sitting, standing, and in each PA intensity during work hours, weekday leisure time, and weekends.

RESULTS

Workplace sitting, standing, or PA were not significantly associated with cognition or mood (P > .05). No significant associations were observed between these variables during weekday leisure time or weekends (P > .05).

CONCLUSIONS

In a cohort of healthy workers, workplace sitting, standing, and PA are not associated with cognition or mood. Further research in this population is needed, examining the influence of workplace behaviors on cognition and mood, because this will contribute to evidence-based workplace guidelines to increase productivity.

Tinnitus and stress in adults: a scoping review

OBJECTIVE

Tinnitus and stress are recurrently reported together. The strength and direction of this relationship is not clear. The aim of this review is to catalogue the evidence of this relationship, how it has been described in adults and which instruments were used.

DESIGN

Five-stage framework was followed. An online search of databases and published journals were conducted. The main inclusion criteria were original studies published in English and conducted in an adult human population, in which both tinnitus and stress were measured using different instruments.

STUDY SAMPLES

5699 records were identified in the searching stage and 50 studies were eligible for data extraction.

RESULTS

Measurements of perceived stress were most frequently used. Tinnitus patients tend to report louder and more bothersome tinnitus when they are stressed, but not all tinnitus patients associated stress with the onset or the severity of their tinnitus. Any positive correlation reported between stress and tinnitus levels varied in strength according to the used instrument. Post-intervention changes in stress and tinnitus levels showed inconsistency.

CONCLUSION

There is considerable room for further research to study the relationship between stress and tinnitus. We highlight principal issues that should be considered in future studies.

The Influence of Refugee Students’ Personal Characteristics on Study Success in Online Education

There is little research on the study success factors of refugee students in higher education. One approach to meeting the growing global demands is to provide online education specifically for refugees. This study examines specific personal characteristics of refugee students and their influence on success and retention in online education. Individual factors such as intrinsic motivation and language proficiency, cognitive functioning, and sociodemographic factors such as gender and country of residence influence retention of refugee students during online studies. The results indicate that sociodemographic factors (e.g., gender), cognitive factors (e.g., English proficiency), and external factors (e.g., country of residence) have a significant influence on study retention on refugee students.

Perceived risks, concession travel pass access and everyday technology use for out-of-home participation: cross-sectional interviews among older people in the UK

Background

The health-promoting qualities of participation as an opportunity for social and cognitive engagement are well known. Use of Everyday Technology such as Smartphones or ATMs, as enabling or disabling factors for out-of-home participation is however under-researched, particularly among older people with and without dementia. Out-of-home participation involves participation in places and activities outside of a person’s home, in public space. Situated within the context of an increasingly technological society, the study investigated factors such as perceived risks, access to a concession travel pass and use of Everyday Technologies, and their relationship with out-of-home participation, among older people in the UK.

Methods

One hundred twenty-eight older people with and without dementia in urban and rural environments in the UK, were interviewed using the Participation in ACTivities and Places OUTside Home (ACT-OUT) Questionnaire and the Everyday Technology Use Questionnaire (ETUQ). Associations between Everyday Technology use, perceived risk of falling, functional impairment, access to a concession travel pass and out-of-home participation were investigated using ordinal regression.

Results

A higher probability of Everyday Technology use (Odds Ratio [OR] = 1.492; 95% Confidence Interval [CI] = 1.041–1.127), perceived risk of falling outside home (OR = 2.499; 95% CI = 1.235–5.053) and, access to a concession travel pass (OR = 3.943; 95% CI = 1.970–7.893) were associated with a higher level of out-of-home participation. However, other types of risk (getting lost; feeling stressed or embarrassed) were not associated with out-of-home participation. Having a functional impairment was associated with a low probability of a higher level of out-of-home participation (OR = .470; 95% CI = .181–1.223). Across the sample, ‘outside home’ Everyday Technologies were used to a higher degree than ‘portable’ Everyday Technologies which can be used both in and outside home.

Conclusions

The study provides insights into perceived risks, access to a concession travel pass and use of Everyday Technologies, and their relationship with out-of-home participation, among older people in the UK. Increased knowledge about factors associated with out-of-home participation may help to guide targeted health and social care planning.

Examining the Relationship Between Engagement and Perceived Stress-Related Cognitive Complaints in the Argentinian Working Population

Stress has a negative impact on cognitive functioning and occupational well-being. The aim of this study was to assess the relationship among perceived stress, cognitive complaints and work engagement in public employees from Córdoba, Argentina. In this cross-sectional study, self-report questionnaires were administered to 240 participants. Spanish versions of the following instruments were used: Perceived Stress Scale (PSS), Utrecht Work Engagement Scale (UWES), Memory Failures in Everyday (MFE), Executive Complaint Questionnaire (ECQ). Statistical analysis included ANOVA, path analysis, and multiple logistic regression. Stressed workers showed lower work engagement and more cognitive complaints, even after adjusting for demographic variables. Negative associations were also observed between work engagement and cognitive complaints, suggesting that cognitive difficulties are related to engagement. Given the relation among stress, cognition, and work engagement, it is important to consider these factors to foster workers’ health and work productivity.

Does cognitive function predict changes in perception of stressful working conditions?

Cognitive health is a key resource for individuals to nurture their employability. We studied the longitudinal association of cognitive function with changes in stressful working conditions, testing a possible reversed causation. We used a sample of employees (N=1,355) participating in two surveys (2006 and 2011) within a German national representative study (GSOEP). Cognitive function was captured by perceptual speed (Symbol Digit Test) and word fluency (Animal Naming Test). Stressful working conditions were measured by the validated short version of the effort-reward imbalance questionnaire. Multivariate linear regression models assessed the impact of perceptual speed and verbal fluency in 2006 on changes in participants' perceptions of effort, reward, effort-reward ratio, and over-commitment between 2006 and 2011, adjusting for socio-demography, behaviours, physical and mental health at baseline. Neither perceptual speed nor verbal fluency was significantly related to changes in perceived working conditions. Our findings did not support the notion of reversed causation.

Work-related stress and cognitive performance among middle-aged adults: The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

Assessing risk factors exposure, such as stress in the workplace during adulthood, may contribute to detecting early signs of cognitive impairment in order to implement effective actions to improve brain health and consequently to decrease cognitive disorders later in life. In this cross-sectional study, we aimed to investigate whether work-related stress is associated with low cognitive performance in middle-aged adults from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) and whether social support mediates this relationship. Work-related stress was evaluated in 9,969 workers using the Demand-Control-Support Questionnaire. Cognitive function was assessed using the verbal fluency, trail-making version B, and delayed recall word tests. Work-related stress was associated with lower performance on the delayed recall, verbal fluency, and executive function tests in middle-aged adults. Social support may mediate the association between work demands and cognitive performance. These findings support that work-related stress is associated with cognitive performance during adulthood.

Fostering ICT use by older workers

Purpose

Adaptation to the requirements of digital economy is especially difficult for older workers, which is a challenge for today’s organizations due to workforce shrinking and ageing. Therefore, the purpose of this paper is to investigate how it is possible to develop older employees’ potential in technology use in the business environment.

Design/methodology/approach

The authors examined how employees at various age perceive barriers during enterprise system (ES) adoption and use. This exploratory study is based on grounded theory and draws from the opinions of 187 Polish ES practitioners.

Findings

With age, emphasis on employees’ perception of mandatory ICT implementation projects is shifting from technology to people-related considerations. For older employees, job security and workload appear the most critical issues in such projects. Age-diverse collaboration appears necessary to address the problems posed by technology-related and demographic changes.

Research limitations/implications

The findings imply that incorporating multiple stakeholder perspectives and age-related considerations into research on ICT adoption appears essential.

Practical implications

ICT adoption in the business environment can be successfully supported by age-balanced team building, cooperation between younger and older employees, and age-adjusted change management initiatives.

Social implications

Supporting older employees during the implementation of mandatory business software should embrace reducing their negative attitudes to ICT-induced change by minimizing their perception of job insecurity.

Originality/value

Unlike many prior studies, the current research places age in the central role and discusses not only how it is possible to support older employees, but also how to leverage their potential in the process of ICT adoption and use in a mandatory setting.

Retirement and decline in episodic memory: analysis from a prospective study of adults in England

BACKGROUND

Work has been associated with cognitive health. We examined whether retirement from work is associated with a decrease in episodic memory and whether this effect differs when considering workers' occupational class.

METHODS

In this prospective study using the English Longitudinal Study of Ageing (ELSA), we examined 1629 persons aged 50-75 years who were in paid work at baseline. A two-slope random effects linear regression centred at retirement was used to study the effect of retirement on episodic memory. The potential effect modification by occupational class was examined.

RESULTS

While memory trajectories show slightly decreasing memory scores before and afterretirement, the decreasing rates for both periods were similar [episodic memory β2b-β2a= -0.03, 95% confidence interval (CI) -0.08, 0.02]. When stratifying by occupational class, there was also no substantial difference in episodic memory trajectories before and after retirement. However, the lower occupational class showed a clear decline in episodic memory with time (pre-retirement β2a = -0.11, 95% CI -0.19, -0.03; post-retirement β2b = -0.13, 95% CI -0.19, -0.07) which was not evident for the higher occupational classes.

CONCLUSIONS

Our results show no observable difference in trajectories of change in episodic memory before and after retirement. However, the steeper memory decline in workers belonging to the lower occupational class may limit their prospect of prolonging their working lives. Hence enrichment programmes for the prevention of memory decline for these workers should be considered.

The cross-sectional association of cognitive stimulation factors and cognitive function among Latino adults in Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

INTRODUCTION

Higher cognitive stimulation (CS) is associated with improved cognition. Sources of CS among Hispanics/Latinos are understudied.

METHODS

In the Hispanic Community Health Study/Study of Latinos 2008 to 2011 (n = 9438), we used finite mixture models to generate latent CS profiles, and multivariate linear regressions to examine associations with cognition in Hispanic/Latino adults (45-74 years). CS included education, occupation, social network, and acculturation. Cognitive measures included the Six-Item Screener, Brief-Spanish English Verbal Learning Test Sum and Recall, Controlled Oral Word Association Test, Digit Symbol Substitution, and Global Cognition.

RESULTS

Two CS profiles emerged, and were labeled "typical" and "enhanced." The enhanced CS profile (22%) had more family connections, bicultural engagements, skilled/professional occupations, education, and higher cognitive scores.

DISCUSSION

An enhanced CS profile emerged from contextual and culturally relevant factors, and was associated with higher cognitive scores across all measures. This provides initial evidence on how factors coalesce to shape cognitive protection in Hispanics/Latinos.

Framework for Considering Productive Aging and Work

OBJECTIVES

The U.S. population is experiencing a demographic transition resulting in an aging workforce. The objective of this article is to elucidate and expand an approach to keep that workforce safe, healthy, and productive.

METHODS

This article elucidates the framework for the National Center for Productive Aging at Work of the National Institute for Occupational Safety and Health. Subject matter experts used a snowball method to review published literature to substantiate elements in the framework.

RESULTS

Evidence-based literature supports a productive aging framework for the workforce involving the following elements: 1) life span perspective; 2) comprehensive and integrated approaches to occupational safety and health; 3) emphasis on positive outcomes for both workers and organizations; and 4) supportive work culture for multigenerational issues.

CONCLUSION

The productive aging framework provides a foundational and comprehensive approach for addressing the aging workforce.

Psychosocial work demands and physical workload decrease with ageing in blue-collar and white-collar workers: a prospective study based on the SLOSH cohort

OBJECTIVES

Psychosocial work demands and physical workload are important causes of ill health. The dramatic demographic changes in society make it important to understand if such factors change with ageing, but this is presently not known. The purpose of the present study was to investigate whether psychosocial work demands and physical workload change across 8 years of ageing, whether occupational groups show different trajectories of change and if such trajectories are reflected in sleep or fatigue.

METHODS

A cohort of 5377 participants (mean age: 47.6±11.6 (SD) years, 43.2% males, 40.2% blue-collar workers) was measured through self-report in five biannual waves across 8 years. Mixed model regression analyses was used to investigate change across ageing.

RESULTS

Psychosocial work demands decreased significantly across 8 years (Coeff: -0.016±0.001), with the strongest decrease in the high white-collar group (Coeff=-0.031±0.003) and the oldest group. Physical workload also decreased significantly (Coeff=-0.032±0.002), particularly in the blue-collar group (Coeff=-0.050±0.004) and in the oldest group. Fatigue decreased, and sleep problems increased with ageing, but with similar slopes in the occupational groups. All effect sizes were small, but extrapolation suggests substantial decreases across a working life career.

CONCLUSIONS

The decrease in psychosocial work demands and physical workload suggests that the burden of work becomes somewhat lighter over 8 years. The mechanism could be 'pure' ageing and/or increased experience or related factors. The gradual improvement in the work situation should be considered in the discussion of the place of older individuals in the labour market, and of a suitable age for retirement. The results also mean that prospective studies of work and health need to consider the improvement in working life with ageing.

Principles, Approaches and Challenges of Applying Big Data in Safety Psychology Research

Big data is now widely used in many fields and is also widely applied to the integration of disciplines. Traditional methods of safety psychology are not well suited for analyzing psychological states, especially in the management of human factors in industrial production. Also, big data now becomes a new way to excavate related insight by analyzing a large amount of psychological data. So, this paper is to propose the concept of big data of safety psychology (BDSP) and to illustrate the challenges of applying big data in safety psychology. First, this paper puts forward the concept of BDSP and analyzes the difference between BDSP and traditional sample data. Subsequently, this paper summarizes the classification standard and basic characteristic of BDSP, explores the framework of BDSP and then constructs a three-dimensional structure of BDSP. Lastly, this paper discusses the challenges of using BDSP. This study is of great help to safety practitioners to solve psychological issues in the safety domain, and points out one of the research trends of human factor in industrial safety.

Age-sensitive job design antecedents of innovative work behavior

Purpose

Integrating the lifespan perspectives on job design and creativity/innovation, the purpose of this paper is to examine the moderating role of chronological age in the relationship between cognitive job demands (i.e. job complexity and job innovation requirements) and individual innovative work behavior (IWB).

Design/methodology/approach

Multilevel regression analyses are employed to analyze survey data of 336 employee–supervisor dyads from 61 departments across three organizations.

Findings

Results demonstrate that age was a significant moderator of the cognitive job demands-IWB relationship. Under the condition of high job complexity, younger employees outperformed their older counterparts. Conversely, older employees attained the same level of IWB as younger colleagues when more job innovation requirements were placed upon them.

Practical implications

IWB needs to be stimulated following different paths and by making job design decisions with regards to cognitive job demands that are dependent on employee age.

Originality/value

Empirical evidence has been provided to support the lifespan perspective on job design, with a special focus given to the cognitive job demands–IWB relationship.

Behavioral health and new models of service delivery for an aging world: Public/private partnerships to develop best practices of care for older adults

Individual and societal initiatives in areas of research, education, and health care policy have resulted in unprecedented gains in life expectancy. It is true that today more people in the world are living longer and have opportunities for higher quality lives than ever before. However, the resulting rapid rise in number of older adults has become a source of concern: Experts of many countries, in anticipation of looming problems, such as overburdened health care and pension systems, are now seeking opportunities to work together to find common solutions for globally-shared problems. The good news is that while all countries are experiencing change brought on by aging populations, the rate of change varies substantially from country to country; differences in historical events have produced differences in demographic profiles. Some countries have relatively large numbers of older adults, comprising large percentages of their populations; others have fewer older adults, with slower growth in numbers and percentages of older adults relative to other age groups. These differences have led to variations for the type and pace of response mounted by individual countries for problems associated with increasingly large older adult populations. In turn, these variations in response provide opportunities for countries to learn from one another. This brief review will outline potential issues associated with aging populations and discuss strengths and challenges for the integration of primary medical care with behavioral health as an innovative, best practices approach to the provision of care for aging persons of the world.
