Factors Associated with Lower Social Activity in German Older Adults at Increased Risk of Dementia: A Cross-Sectional Analysis.

Background: Studies demonstrate associations between low social activity in older adults and cognitive decline. Little has been investigated regarding which factors are associated with low social activity in older adults at increased risk of dementia. Objective: We investigate which sociodemographic, psychological, health-related, and environmental factors are associated with low social activity in older adults at increased risk of dementia. Additionally, we describe the stages of health behavior change, the types of social activities, and the duration of the current level of social activity. Methods: We used baseline data of 1,015 participants from the AgeWell.de trial. We conducted logistic and Poisson regression analyses to investigate factors associated with low social activity. We report descriptive statistics on the stages of change in the sample, the types of social activities most frequently pursued, and the duration of the current level of social activity. Results: Lower income, non-usage of public transport, depressive symptoms, cognitive, mobility, and hearing impairment were negatively associated with social activity. The majority of the sample was in the maintenance stage, followed by the precontemplation stage. The most common social activities were traveling and hobbies with others. Participants have maintained their current level of social activity for several years. Conclusions: We identified a lack of resources (income, transport), depressive symptoms and poorer health (cognitive, mobility and hearing impairment) as barriers to social activity. Interventions promoting social activity in older adults at risk of dementia may specifically target individuals with these risk factors. Low-threshold opportunities for social activity may be particularly beneficial.

Lifestyle and incident dementia: A COSMIC individual participant data meta­analysis.

INTRODUCTION: The LIfestyle for BRAin Health (LIBRA) index yields a dementia risk score based on modifiable lifestyle factors and is validated in Western samples. We investigated whether the association between LIBRA scores and incident dementia is moderated by geographical location or sociodemographic characteristics. METHODS: We combined data from 21 prospective cohorts across six continents (N = 31,680) and conducted cohort-specific Cox proportional hazard regression analyses in a two-step individual participant data meta-analysis. RESULTS: A one-standard-deviation increase in LIBRA score was associated with a 21% higher risk for dementia. The association was stronger for Asian cohorts compared to European cohorts, and for individuals aged ≤75 years (vs older), though only within the first 5 years of follow-up. No interactions with sex, education, or socioeconomic position were observed. DISCUSSION: Modifiable risk and protective factors appear relevant for dementia risk reduction across diverse geographical and sociodemographic groups. HIGHLIGHTS: A two-step individual participant data meta-analysis was conducted. This was done at a global scale using data from 21 ethno-regionally diverse cohorts. The association between a modifiable dementia risk score and dementia was examined. The association was modified by geographical region and age at baseline. Yet, modifiable dementia risk and protective factors appear relevant in all investigated groups and regions.

Behind the times? Associations of working-time autonomy with health-related and occupational outcomes in health care personnel- a latent profile analysis.

BACKGROUND: In the light of personnel shortage, the health care sector is facing the challenge to combine increasing employees' as well as patients' needs. The aim of this study was to investigate the association between working-time autonomy and health-related (fatigue, psychosomatic complaints and work ability), as well as occupational outcomes (job satisfaction and turnover intention) in a large sample of health care employees. METHOD: Based on data of the BauA-Working Time survey, a sample of n = 1,093 employees working in the health care sector was analysed. Outcomes were assessed by the German Fatigue Scale, the Work Ability-Index and single-item measurements. Besides descriptive analyses, latent profile analysis (LPA) was used to determine clusters of employees based on working-time autonomy. Subsequently, regression analyses have been conducted to examine the association between autonomy clusters with health-related and occupational outcomes, controlling for sociodemographic characteristics and employment status. RESULTS: LPA revealed that a three-cluster model was most suitable: high autonomy (cluster 1), medium autonomy (cluster 2) and low autonomy (cluster 3). The extracted profiles of working-time autonomy differed significantly in terms of sociodemographic and occupational characteristics, but not in terms of average working hours per week or monthly household income. The multivariate regression analysis revealed that being in the low-autonomy cluster was associated with more psychosomatic health complaints (IRR: 1.427, p = 0.008), lower work ability (OR 0.339, p < 0.001), as well as less job satisfaction (OR 0.216, p < 0.001). DISCUSSION: Overall, the analyses indicate that it is crucial to prospectively consider working-time autonomy as an important factor of satisfaction, well-being and turnover intention in health care employees.

Profiles of met and unmet care needs in the oldest-old primary care patients with depression - results of the AgeMooDe study.

BACKGROUND: Unmet care needs have been associated with an increased risk of depression in old age. Currently, the identification of profiles of met and unmet care needs associated with depressive symptoms is pending. Therefore, this exploratory study aimed to identify profiles of care needs and analyze associated factors in oldest-old patients with and without depression. METHODS: The sample of 1092 GP patients aged 75+ years is based on the multicenter study "Late-life depression in primary care: needs, health care utilization and costs (AgeMooDe)". Depression (i.e. clinically meaningful depressive symptoms) was determined using the Geriatric Depression Scale (GDS) (cutoff score ≥ 4). Needs of patients were assessed using the Camberwell Assessment of Need for the Elderly (CANE). Associated sociodemographic and clinical factors were examined, and latent class analysis identified the need profiles. RESULTS: The main result of the study indicates three need profiles: 'no needs', 'met physical needs', and 'unmet social needs'. Members of the 'met physical needs' (OR = 3.5, 95 %-CI: 2.5-4.9) and 'unmet social needs' (OR = 17.4, 95 %-CI: 7.7-39.7) profiles were significantly more likely to have depression compared to members of the 'no needs' profile. LIMITATIONS: Based on the cross-sectional design, no conclusions can be drawn about the causality or direction of the relationships between the variables. CONCLUSIONS: The study results provide important insights for the establishment of needs-based interventions for GPs. Particular attention should be paid to the presence of unmet social needs in the oldest-old GP patients with underlying depressive symptoms.

A multidomain intervention against cognitive decline in an at-risk-population in Germany: Results from the cluster-randomized AgeWell.de trial.

INTRODUCTION: We investigated the effectiveness of a multidomain intervention to preserve cognitive function in older adults at risk for dementia in Germany in a cluster-randomized trial. METHODS: Individuals with a Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) risk score ≥ 9 aged 60 to 77 years were recruited. After randomization of their general practitioner (GP), patients received a multidomain intervention (including optimization of nutrition and medication, and physical, social, and cognitive activity) or general health advice and GP treatment as usual over 24 months. Primary outcome was global cognitive performance (composite z score, based on domain-specific neuropsychological tests). RESULTS: Of 1030 participants at baseline, n = 819 completed the 24-month follow-up assessment. No differences regarding global cognitive performance (average marginal effect = 0.010, 95% confidence interval: -0.113, 0.133) were found between groups at follow-up. Perceived restrictions in intervention conduct by the COVID-19 pandemic did not impact intervention effectiveness. DISCUSSION: The intervention did not improve global cognitive performance. HIGHLIGHTS: Overall, no intervention effects on global cognitive performance were detected. The multidomain intervention improved health-related quality of life in the total sample. In women, the multidomain intervention reduced depressive symptoms. The intervention was completed during the COVID-19 pandemic.

The effect of depressive symptoms on quality of life and its different facets in the oldest age population: evidence from the AgeQualiDe prospective cohort study.

PURPOSE: The present study aims to investigate the prospective effect of depressive symptoms on overall QoL in the oldest age group, taking into account its different facets. METHODS: Data were derived from the multicenter prospective AgeCoDe/AgeQualiDe cohort study, including data from follow-up 7-9 and n = 580 individuals 85 years of age and older. Overall QoL and its facets were assessed using the WHOQOL-OLD instrument. The short form of the geriatric depression scale (GDS-15) was applied to assess depressive symptoms. Cognitively impaired individuals were excluded. Linear mixed-effects models were used to assess the effect of depressive symptoms on QoL. RESULTS: Depressive symptoms were significantly associated with overall QoL and each of the different facets of WHOQOL-OLD, also after adjustment for time and sociodemographic characteristics such as age, gender, education, marital status, living situation, and cognitive status. Higher age and single as well as divorced marital status were also associated with a lower QoL. CONCLUSION: This work provides comprehensive longitudinal results on the relationship between depressive symptoms and QoL in the oldest age population. The results underscore the relevance of tailored and targeted care planning and the development of customized interventions.

[Comparison of the Documented Dementia Diagnoses in German Primary Care with the Prevalence Estimate for 2021]. / Demenzdiagnosen in deutschen Hausarztpraxen ­ Ein Vergleich mit der Prävalenzschätzung für das Jahr 2021.

BACKGROUND: A current prevalence estimate predicted the number of people with dementia (PwD) with 1.8 million in 2021. This estimation is based on data from different sources especially from field studies and does not reflect the recognized and documented cases in primary care. We, therefore, aim to compare the prevalence of diagnosed PwD in general practitioner (GP) practices with these estimates of the general population. METHODS: The number of diagnosed PwD in 946 GP practices with 2.8 million patients in 2021 was compared with the prevalence estimate of the German Alzheimer Society for 83 million inhabitants in Germany. RESULTS: Dementia diagnoses were documented less frequently in GP practices compared to the prevalence estimate (1.88% vs 2.16%), especially the age groups 80+years were less likely present in GP practices prevalence. DISCUSSION: There is still potential for optimizing dementia diagnostics in primary care, especially in patients 80 or older.

[Influence of guideline recommendations, care structures and individual factors on the use of psychosocial therapies in severely mentally ill people]. / Einfluss von Leitlinienempfehlungen, Versorgungsstrukturen und individuellen Faktoren auf die Inanspruchnahme von psychosozialen Therapien bei schwer psychisch kranken Menschen.

OBJECTIVE: The influence of guideline recommendations and other factors on the utilization of psychosocial interventions in people with severe mental illness was examined. METHODS: Data from a cross-sectional study of 397 people with severe mental illness were analysed descriptively. RESULTS: Patients are less likely to receive therapies with a strong recommendation compared to other levels of recommendation. Various other factors are diffusely associated with utilization rates, but no ubiquitous predictors could be identified across all therapies. CONCLUSION: Current practice in the use of psychosocial interventions does not follow guideline recommendation strength. Interventions with strong recommendations are probably not available across services. Consequently, routine practice is not able to follow guideline recommendations according to their strength. Other consistent predictors could not be identified.

Psychometric Evaluation of the A-NKS: A Diagnostic Instrument to Assess Impairment of Activities of Daily Living in Mild and Major Neurocognitive Disorder According to DSM-5.

BACKGROUND: Activities of daily living (ADL) functioning are important in the diagnosis of neurocognitive disorders (NCD), yet no standardized and validated instrument exist based on international classification systems. OBJECTIVE: We aimed to psychometrically evaluate the differentiated assessment of ADL and instrumental ADL (IADL) impairments due to NCD according to DSM-5 criteria (Instrument für die Erfassung von Alltagsbeeinträchtigungen bei Neurokognitiven Störungen; A-NKS). METHODS: We conducted a pilot study involving 92 participant-informant dyads of participants with mild or major NCDs, cognitively healthy individuals, and an informant, to test acceptability, internal consistency, and convergent validity with similar measures. RESULTS: Both A-NKS versions demonstrated excellent internal consistency (α= 0.95 -0.99) and correlate with other instrumental ADL instruments (participant [informant]: Barthel Index: rs = -0.26, p≤0.05 [rs = -0.30, p≤0.01]; Amsterdam IADL: rs = 0.59, p≤0.01 [rs = 0.48, p≤0.01]; SIDAM ADL: rs = 0.46, p≤0.001 [rs = 0.47, p≤0.001]). Additionally, there are correlations with the scale autonomy of the WHOQOL-OLD (rs = -0.50, p≤0.001 [rs = -0.37, p≤0.001]) and physical, as well as cognitive activities (rs = -0.39, p≤0.001 [rs = -0.50, p≤0.001]). They were well-accepted by participants and informants. CONCLUSIONS: The A-NKS is an instrument with acceptable psychometric properties to assess ADL due to neurodegenerative decline in healthy individuals, and those with mild or major NCD. Further research is needed to confirm reliability and validity and investigate the factor structure.

[How Successful is the Participation of People with Mental Illness and Family Members in the Development of Evidence- and Consensus-Based Clinical Practice Guidelines? Results of a Survey in Psychiatry]. / Wie gelingt die Einbindung von Betroffenen- und Angehörigenvertreter:innen in die Entwicklung von evidenz- und konsensbasierten Behandlungsleitlinien? Ergebnisse einer Umfrage im Fachbereich Psychiatrie.

OBJECTIVE: The study examines how successful the participation of people with mental illness and family members is currently in the development of psychiatric guidelines. METHODS: Survey results of N=561 (Response 37%) guideline developers are analyzed. RESULTS: Involvement of affected individuals succeeds more often than that of family members (61% vs. 55%). 68% felt that this participation was central to successful guideline development. 51% perceived discrepancies between empirical evidence and experience perspective. 33-36% perceived a lack of appreciation of experience expertise, 37% an insufficient representation and 46% an inequality in consensus building. 45% did not see barriers effectively removed. CONCLUSION: There remain challenges in the participation of people with mental illness and family members. There is an increasing awareness that their participation is central.

Determinants of psychosocial factors amongst the oldest old: Longitudinal evidence based on the representative "survey on quality of life and subjective well-being of the very old in North Rhine-Westphalia".

OBJECTIVES: There are few studies investigating the determinants of psychosocial outcomes using data exclusively from the oldest old; and even fewer that use longitudinal data. Thus, our aim was to explore the determinants of psychosocial factors (in terms of life satisfaction, loneliness, and depressive symptoms) amongst the oldest old (also stratified by sex) based on representative, longitudinal data from Germany. METHODS/DESIGN: Data from "Survey on quality of life and subjective well-being of the very old in North Rhine-Westphalia (NRW80+)" were used. This study includes community-dwelling and institutionalized individuals aged 80 years and above (n = 1760 observations in the analytical sample) located in North Rhine-Westphalia (the most populous state in Germany). The mean age was 86.6 years (SD: 4.3 years). Established instruments were used to quantify life satisfaction, loneliness, and depressive symptoms. Linear FE regressions were used in this study to mitigate the challenge of unobserved heterogeneity. Sex-stratified regressions were also conducted. RESULTS: Regressions showed that the loss of a spouse was significantly associated with worsening psychosocial factors (in terms of increases in depressive symptoms and loneliness). Furthermore, regressions revealed that increases in functional impairment were significantly associated with poorer psychosocial outcomes. CONCLUSIONS: This longitudinal study enhanced our understanding of the factors contributing to poorer psychosocial outcomes among the oldest old. Efforts to avoid or postpone functional impairment may contribute to more favorable psychosocial outcomes. Moreover, our current study underlines the importance of spousal relationships for psychosocial outcomes in the oldest age group.

The different areas of chronic stress and food addiction: Results from the LIFE-Adult-Study.

There is an empirical association between stress and symptoms of food addiction (FA), but it is still not clear which domains of stress are the most relevant when it comes to FA, limiting the ability of researchers and practitioners to address problematic eating-related health outcomes. In order to address this gap in the literature, we analysed how different domains of chronic stress are related to FA. We used data from a subsample of the LIFE-Adult-Study (N = 1172), a German cohort study. We conducted a linear regression analysis with stress domains (Trier Inventory for Chronic Stress, TICS) as predictors of FA (Yale Food Addiction Scale, YFAS). In the second regression analysis we included sociodemographic variables, personality, and smoking as control variables. There was a significant and positive association between Social Overload, Work Discontent, Excessive Demands from Work, and Chronic Worrying and FA. After adding control variables, only Social Overload, Excessive Demands from Work, and Chronic Worrying remained significant predictors. Connections between stress domains and FA can serve as starting points for the development of meaningful interventions that support individuals self-care strategies (Social Overload), complexity management (Excessive Demands from Work), and coping with negative emotions (Chronic Worrying).

The development of suicide risk in people with severe mental disorders during the first year of the COVID-19 pandemic: a claims-based cohort study.

PURPOSE: In this study, we assess how the first and second waves of the COVID-19 pandemic influenced the suicide risk of patients with severe mental disorders in Germany. METHODS: We analyzed German health insurance claims data to compare the suicide risk of patients with severe mental disorders before and during the pandemic. We included n = 690,845 patients between October 2019 and March 2020 and n = 693,457 patients the corresponding period of the previous year and applied entropy balancing to adjust for confounding covariates. Given that the cause of death was unknown, we defined potential suicides as deaths of patients with a history of intentional self-harm whose passing could not be explained by COVID-19. Potential suicides were tracked in both cohorts over one year and compared using logistic regression. RESULTS: 128 potential suicides were identified in the period during and 101 before the pandemic. This corresponded to a significant increase in the risk for potential suicide of 27.4% compared to the control period (ß = 0.24, z = 1.82, p < 0.05). CONCLUSION: The noticeable increase in the risk for potential suicide for patients with severe pre-existing mental disorders emphasizes the call for additional efforts to prevent suicide and to help patients cope with their mental illness in the aftermath of the COVID-19 crisis.

Older adults' awareness of modifiable risk and protective factors for dementia and interest in eHealth interventions for brain health: a comparison between the Netherlands and Germany.

BACKGROUND: Evidence on modifiable risk factors for dementia is accumulating rapidly, including e.g. smoking, hypertension, and diabetes. Comparing knowledge of risk factors for dementia and factors associated with knowledge and motivation to learn about dementia risk reduction in different countries may support the design of tailored public health campaigns. We investigated (1) differences in knowledge of risk and protective factors for dementia between the Netherlands and Germany, and interest in (2) information on brain health and (3) eHealth for brain health. MATERIALS AND METHODS: Population-based telephone (Germany) or web-based surveys (Netherlands) were conducted among adults aged 60-75 (ntotal=614; Germany: n = 270; Netherlands: n = 344), assessing sociodemographic factors, knowledge of risk and protective factors for dementia, interest in information on brain health and respective eHealth-tools. Correlates of knowledge, interest in information on brain health and eHealth for brain health were analyzed using multivariable regression, by country and in pooled analyses. RESULTS: In the total sample (Mage: 67.3 (SD: 4.3) years; %female: 48.6), knowledge of risk and protective factors (sum score assessing number of correctly identified factors) was higher among German participants (M (SD) = 7.6 (2.5) vs. 6.0 (4.3), p < .001). This was confirmed using linear regression analyses, controlling for sociodemographic covariates (b = 1.51; 95% CI: 1.00; 2.01). High education was linked to better knowledge of risk and protective factors (b = 1.61; 95% CI: 0.89; 2.34). Controlling for covariates, interest in information on brain health (OR: 0.05, 95% CI: 0.02; 0.09) and eHealth for brain health (OR: 0.40, 95% CI: 0.25; 0.65) was lower in German participants. Widowed participants were less interested in information on brain health, while widowed and single participants expressed less interest in eHealth for brain health in pooled analyses. Further associations between sociodemographic factors, interest in information on brain health and eHealth for brain health by country were detected. DISCUSSION: Engaging older adults in the design of eHealth interventions and cooperation with trusted sources, e.g., general practitioners, might enhance appreciation of eHealth for brain health. Education on risk and protective factors for dementia is warranted in both countries. However, differences in recruitment and assessment need to be acknowledged.

Family History of Dementia in Old-Age Participants with Subjective Memory Complaints Predicts Own Risk for Dementia in a Longitudinal Multi-Center Cohort Study.

BACKGROUND: Subjective memory complaints and family history of dementia are possibly intertwined risk factors for the own subsequent dementia risk and Alzheimer's disease. However, their interaction has rarely been studied. OBJECTIVE: To study the association between subjective memory complaints and family history of dementia with regard to the own subsequent risk of dementia. METHODS: Cross-sectional and longitudinal analyses over a follow-up period of up to 13 years were conducted in a population sample of participants without dementia at baseline (n = 3,256, mean age = 79.62 years), using group comparisons and Cox proportional hazards models. RESULTS: Cross-sectionally, participants with subjective memory complaints were significantly more likely to report family history of dementia. Longitudinally, family history of dementia (FH) was significantly associated with subsequent dementia in the subjective memory complaints (SMC) group, but not in those without SMC. A relative excess risk due to interaction analysis confirmed a significant FHxSMC-interaction. CONCLUSIONS: Family history of dementia was a predictor of incident dementia in those with SMC, which can serve as an additional, clinically relevant criterion to gauge the risk of dementia in older-aged subjects with SMC with and without objective cognitive impairment.

Temporal and spatial changes in the provision of mental health care during the COVID-19 pandemic in Germany: a claims-based cohort study on patients with severe mental disorders.

PURPOSE: Major lockdowns were imposed in Germany from March until May 2020 and from December 2020 until May 2021. We studied the influence of these lockdowns, the strain on intensive care units and the strictness of COVID-19-related containment strategies on the utilization of mental health care among patients with severe mental disorders. METHODS: We used health insurance claims data to identify n = 736,972 patients with severe mental disorders shortly before the pandemic and n = 735,816 patients a year earlier. We applied entropy balancing to adjust for baseline differences by district. For a 12-month follow-up, we modeled monthly changes in utilization through meta-analytic models using both the COVID-19 stringency index and intensive care unit cases per 100,000 inhabitants as predictors. Our outcomes were changes in psychiatric hospital days and time treated by outpatient psychiatrists. RESULTS: Psychiatric hospital days declined by at least 7.7% in all calender month during the pandemic. Peak reduction rates were observed in April (- 27.9%), May (- 22.3%) 2020 and January 2021 (- 18.3%). Utilization changes were associated with the stringency index and the second lockdown. Time treated by psychiatrists was shorter in April (- 16.2%) and May (- 11.5%) 2020 and in January 2021 (- 10.5%), which was partially offset by higher utilization in June and September 2020. These utilization changes were associated with the stringency index and the strain on intensive care units during both lockdowns. CONCLUSION: Hospitals did not maintain the level of utilization during the pandemic, while outpatient psychiatrists adapted more quickly, presumably due to digital and telemedical care.

[Burnout in hospital-based surgeons. Approaches for prevention?] / Burn-out bei chirurgisch tätigen Klinikärzten. Ansätze für die Prävention?

BACKGROUND: Burnout among physicians is increasingly recognized as a public health issue including its scientific, political, and societal relevance. The effects of burnout go far beyond physician health as they affect the quality of care, patient safety, medical errors, and efficiency of health care. OBJECTIVE: Assessment of the risk of burnout for hospital-based surgeons as well as associations between surgeon burnout and several work-related and person-related factors. METHODS: From the representative Saxony physician survey from 2019, we utilized the subsample of 231 hospital-based surgeons. We conducted a regression analysis with workload, job satisfaction, work-life balance (WLB), resilience, inability to recover and health complaints as predictors of burnout (Maslach burnout inventory-General survey, MBI-GS). RESULTS: Nearly half of the sample were female (49.4%), the average age was 42.0 years, 4.8% of participants exhibited burnout, 45.9% with some symptoms and 49.4% no burnout. Multivariate analysis showed significant positive associations between health complaints, inability to recover, a lack of job-based self-fulfillment and burnout. There were significant negative connections between WLB, the wish to remain in the job and burnout. CONCLUSION: Burnout is a serious problem for surgeons. Preventive measures should focus on risk factors associated with the workplace and organization of work. Interventions targeted at the individual level should start at an early career stage.

Mental resources, mental health and sociodemography: a cluster analysis based on a representative population survey in a large German city.

BACKGROUND: Mental resources such as optimism and social support are important to face different stressors. The aim of this study is to identify groups in the population that are similar in terms of their mental resources. METHODS: For this purpose, a randomly selected general population community sample was used, representative for the city of Leipzig, Germany. In a two-stage process, three clusters were identified using hierarchical cluster analysis and the K-means method and then tested with a multinomial logistic regression analysis for differences in sociodemographic characteristics. RESULTS: Three clusters were identified which vary in their extent of social support and optimism. In distinguishing between those with higher and lower (medium or poor) mental resources, male gender, unemployment, being born abroad and low household income are risk factors for having fewer mental resources. Internal migrants from West Germany and persons with children at home have a higher chance of being in the type with good mental resources. The groups with medium and lower mental resources differ significantly only by variables living with a partner and employment. CONCLUSION: Our results indicate that good mental resources are associated with good mental health. Special mental health care programs, focusing in particular on the needs of vulnerable groups with poor mental resources within a society, should be implemented.
