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.

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.

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.

COVID-19 government measures and their impact on mental health: a cross-sectional study of older primary care patients in Germany.

Background: With the outbreak of COVID-19, government measures including social distancing and restrictions of social contacts were imposed to slow the spread of the virus. Since older adults are at increased risk of severe disease, they were particularly affected by these restrictions. These may negatively affect mental health by loneliness and social isolation, which constitute risk factors for depressiveness. We aimed to analyse the impact of perceived restriction due to government measures on depressive symptoms and investigated stress as mediator in an at-risk-population in Germany. Methods: Data were collected in April 2020 from the population of the AgeWell.de-study, including individuals with a Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) score ≥9, using the depression subscale of the Brief Symptom Inventory (BSI-18) and the Perceived Stress Scale (PSS-4). Feeling restricted due to COVID-19 government measures was surveyed with a standardized questionnaire. Stepwise multivariate regressions using zero-inflated negative binomial models were applied to analyse depressive symptoms, followed by a general structural equation model to assess stress as mediator. Analysis were controlled for sociodemographic factors as well as social support. Results: We analysed data from 810 older adults (mean age = 69.9, SD = 5). Feeling restricted due to COVID-19 government measures was linked to increased depressiveness (b = 0.19; p < 0.001). The association was no longer significant when adding stress and covariates (b = 0.04; p = 0.43), while stress was linked to increased depressive symptoms (b = 0.22; p < 0.001). A final model confirms the assumption that the feeling of restriction is mediated by stress (total effect: b = 0.26; p < 0.001). Conclusion: We found evidence that feeling restricted due to COVID-19 government measures is associated with higher levels of depressive symptoms in older adults at increased risk for dementia. The association is mediated by perceived stress. Furthermore, social support was significantly associated with less depressive symptoms. Thus, it is of high relevance to consider possible adverse effects of government measures related to COVID-19 on mental health of older people.

[What does the population know about risk and protective factors for dementia? An international review of the current state of knowledge in various countries]. / Was weiß die Bevölkerung über Risiko- und Schutzfaktoren für Demenz? Eine internationale Übersicht zum aktuellen Kenntnisstand in verschiedenen Ländern.

BACKGROUND: The scientific state of knowledge on modifiable risk factors for dementia has greatly improved in recent years. The established risk and protective factors include physical and social inactivity, hypertension, diabetes mellitus, excessive alcohol consumption and smoking; however, it is assumed that this knowledge is so far insufficiently disseminated among the general population, indicating untapped potential for primary prevention of dementia. OBJECTIVE: To assess the state of knowledge on established risk and protective factors for dementia in the general population. MATERIAL AND METHODS: Based on a systematic literature search in the PubMed database, international studies that investigated the knowledge on modifiable risk and/or protective factors for dementia in samples from the general population were identified. RESULTS AND CONCLUSION: A total of 21 publications were included in the review. The majority of publications (n = 17) collated risk and protective factors using closed questions, while n = 4 studies used open questions. Lifestyle factors, e.g. cognitive, social and physical activity, were most frequently named as protective against dementia. Furthermore, many participants recognized depression as a risk factor for dementia. Knowledge of cardiovascular risk constellations for dementia, such as hypertension, hypercholesterolemia or diabetes mellitus were much less known among the participants. The results indicate that there is a need for a targeted clarification of the role of pre-existing cardiovascular diseases as risk factors for dementia. Studies assessing the state of knowledge on social and environmental risk and protective factors for dementia are currently scarce.

Traffic noise annoyance in the LIFE-adult study in Germany: Exposure-response relationships and a comparison to the WHO curves.

BACKGROUND: Noise annoyance is the second-highest cause of lost disability-adjusted life-years due to environmental noise in Europe. Evidence on exposure-response relationships (ERRs) for traffic noise annoyance with more accurate exposure values is still needed. OBJECTIVES: In an analysis of the population-based LIFE-Adult study in Leipzig, Germany, we aimed to investigate the effect of road, railway (train and tram), and aircraft noise on high annoyance (HA). METHODS: Traffic exposure data was taken for 2012 and data on noise annoyance was evaluated between 2018 and 2021. HA was defined according to international standardized norms. We calculated risk estimates using logistic regression, controlling for age, sex, and socioeconomic status, and compared our ERRs with those from the last WHO review on this topic. RESULTS: Aircraft noise had the highest relative risk for noise-related HA (OR = 12.7, 95% CI: 9.37-17.10 per 10 dB Lden increase). The road and railway traffic risk estimates were similar to each other (road: OR = 3.55, 95% CI: 2.78-4.54; railway: OR = 3.31, 95% CI: 2.77-3.97 per 10 dB Lden increase). Compared to the WHO curves, the proportion of highly annoyed individuals was somewhat lower for road and rail traffic noise, but higher for aircraft noise. DISCUSSION: Aircraft noise is particularly annoying. There were differences between our study's ERRs and those in the WHO review, especially for aircraft noise. These differences may be partly explained by the improved accuracy of the exposure values, as we considered secondary road networks and tram noise, and by a lack of a nighttime flight ban at the Leipzig airport. Geographical, regional and climatic variations, inconsistency in HA cut-offs, as well as temporal developments in the annoyance experience may also explain the differences. Since ERRs serve as a basis for decision making in public policies, regular updates of the curves based on new evidence is recommended.

Short report: A trend analysis of attitudes towards early diagnosis of dementia in Germany.

BACKGROUND: Early detection of dementia provides numerous benefits for those living with dementia and their relatives and healthcare systems at large. Methods available for early diagnosis have improved significantly over the past years. Therefore, we examined whether support for offering an early diagnosis of dementia and willingness to pursue a respective early diagnosis have changed in Germany over the last decade. METHOD: We compared findings from two representative telephone surveys conducted among older adults in Germany (≥ 60 years of age) in 2011 and 2022, assessing support for offering an early diagnosis of dementia and willingness to pursue a respective early diagnosis in a sample of n = 879 individuals (mean age: 72.9, range: 60-98 years, % female: 58.8). Group comparisons using Chi2- and t-tests and multivariable regression analyses were conducted, regressing support of an early diagnosis of dementia and willingness to pursue a respective early diagnosis on age, gender, education, employment status, belief in preventability of dementia and time of survey. RESULTS: Support for offering an early diagnosis of dementia was high both in 2011 (90.7%) and 2022 (79.2%), but declined over time (OR: .39; 95% CI: .25; .63). Willingness to pursue an early diagnosis of dementia declined from 70.7% to 60.1% in the same period (OR: .62; 95% CI: .45; .86). Belief in preventability of dementia was linked to support for offering an early diagnosis (OR: 1.88, 95% CI: 1.25; 2.83) and willingness to pursue an early diagnosis of dementia (OR: 1.52; 95% CI: 1.12; 2.07). Older participants less often supported offering an early diagnosis of dementia (OR: .97, 95% CI: .95; .99). CONCLUSION: Support for offering an early diagnosis of dementia and willingness to pursue a respective diagnosis is high in the older German public, but lower than reported previously. Improving knowledge on modifiable risk factors and better understanding of individual motives underlying endorsement or refusal of an early diagnosis may increase acceptance in the general public.

Traffic-Related High Sleep Disturbance in the LIFE-Adult Cohort Study: A Comparison to the WHO Exposure-Response-Curves.

Sleep is negatively affected by environmental noise. In the present study, we investigated self-reported high sleep disturbances (being "highly sleep disturbed"-HSD) from road traffic (primary and secondary road networks), rail (train and tram) and air traffic noise in the LIFE-Adult cohort study in Leipzig, Germany. For this, we used exposure data from 2012 and outcome data of Wave 2 (collected during 2018-2021). HSD was determined and defined according to internationally standardized norms. The highest risk for transportation noise-related HSD was found for aircraft noise: the odds ratio (OR) was 19.66, 95% CI 11.47-33.71 per 10 dB increase in Lnight. For road and rail traffic, similar risk estimates were observed (road: OR = 2.86, 95% CI 1.92-4.28; rail: OR = 2.67, 95% CI 2.03-3.50 per 10 dB Lnight increase). Further, we compared our exposure-risk curves with the curves of the WHO environmental noise guidelines for the European region. The proportion of individuals with HSD for a given noise level was lower for rail traffic but higher for aircraft noise in the LIFE study than in the WHO curves. For road traffic, curves are not directly comparable because we also included the secondary road network. The results of our study add to the body of evidence for increased health risks by traffic noise. Moreover, the results indicate that aircraft noise is particularly harmful to health. We recommend reconsidering threshold values for nightly aircraft exposure.

Beneficial and Impeding Factors for the Implementation of Health-Promoting Lifestyle Interventions-A Gender-Specific Focus Group Study.

(1) Background: The prevalence of dementia increases and so does the number of interventions that address modifiable risk factors for dementia. Recent evidence suggests that there are gender differences in the prevalence of those lifestyle factors as well as in the effectiveness of interventions. This study aims to identify differences in factors that benefit or hinder the effectiveness of interventions since a target group's perspective gets more relevant. (2) Methods: Two focus groups, a female (n = 11) and a male (n = 8) group, were interviewed, audio recorded and transcribed. Qualitative analyses were performed and main- and subcategories were identified. (3) Results: Main differences were observed including aspects of lifestyle changes (e.g., respective diet and importance of an active lifestyle) and gender-typical behavior and perception by relevant healthcare actors. (4) Conclusions: Identified differences might help to address and raise the efficiency of lifestyle interventions. Further, the importance of social aspects and retirement as an auspicious moment to start interventions were identified as relevant by study participants.

Knowledge of risk and protective factors for dementia in older German adults A population-based survey on risk and protective factors for dementia and internet-based brain health interventions.

BACKGROUND: Evidence on potentially modifiable risk factors for dementia is accumulating rapidly, including e.g. physical inactivity, hypertension, or diabetes. It is unclear to what extent these risk factors are known among the general population in Germany. We investigated knowledge on risk and protective factors for dementia and openness to eHealth interventions for brain health in the older general population in Germany. METHODS: A population-based telephone survey among randomly selected community-dwelling adults aged ≥ 60 years was conducted. We assessed sociodemographic factors, knowledge on risk and protective factors for dementia, openness towards eHealth and psychosocial outcomes (health literacy, resilience). Factors associated with interest in information on brain health and openness towards eHealth interventions were assessed using multivariable logistic regression. RESULTS: Of n = 500 respondents (mean age: 74.8 years, % female: 62.8), 67.9% believed that dementia risk is modifiable. Participants mostly endorsed physical and cognitive activity as protective factors and social isolation as a risk factor. Knowledge on cardiovascular risk factors was low to moderate. 38.0% were interested in information on dementia risk reduction. Better knowledge of risk factors for dementia and higher age were linked to interest in information on brain health. Being widowed and higher levels of health literacy were associated with lower interest in information. Openness to eHealth interventions was moderate (46.2%). Younger age, better knowledge of risk and protective factors were linked to openness towards eHealth tools, as was knowing someone with dementia and interest in information on brain health. CONCLUSION: Belief in preventability of dementia was higher in our sample than previously reported. However, knowledge on cardiovascular risk factors for disease was insufficient and more information and intervention approaches targeted at older adults are needed. Interest in information on dementia risk reduction and eHealth approaches was moderate, and further studies are warranted to assess needs and concerns of older adults regarding dementia prevention.

Association of mental demands in the workplace with cognitive function in older adults at increased risk for dementia.

OBJECTIVES: Growing evidence suggests a protective effect of high mental demands at work on cognitive function in later life. However, evidence on corresponding associations in older adults at increased risk for dementia is currently lacking. This study investigates the association between mental demands at work and cognitive functioning in the population of the AgeWell.de-trial. METHODS: Cross-sectional investigation of the association between global cognitive functioning (Montreal Cognitive Assessment) and mental demands at work in older individuals at increased risk for dementia (Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE)score ≥ 9; n = 941, age: 60-77 years). Occupational information was matched to Occupational Information Network (O*NET)-descriptors. Associations between cognitive function and O*NET-indices executive, verbal and novelty were investigated using generalized linear models. RESULTS: Higher values of index verbal (b = .69, p = .002) were associated with better cognitive function when adjusting for covariates. No association was observed for indices executive (b = .37, p = .062) and novelty (b = .45, p = .119). Higher education, younger age, and employment were linked to better cognitive function, while preexisting medical conditions did not change the associations. Higher levels of depressive symptomatology were associated with worse cognitive function. CONCLUSIONS: Higher levels of verbal demands at work were associated with better cognitive function for older adults with increased dementia risk. This suggests an advantage for older persons in jobs with high mental demands even after retirement and despite prevalent risk factors. Longitudinal studies are warranted to confirm these results and evaluate the potential of workplaces to prevent cognitive decline through increased mental demands.

Recruitment and Baseline Characteristics of Participants in the AgeWell.de Study-A Pragmatic Cluster-Randomized Controlled Lifestyle Trial against Cognitive Decline.

Targeting dementia prevention, first trials addressing multiple modifiable risk factors showed promising results in at-risk populations. In Germany, AgeWell.de is the first large-scale initiative investigating the effectiveness of a multi-component lifestyle intervention against cognitive decline. We aimed to investigate the recruitment process and baseline characteristics of the AgeWell.de participants to gain an understanding of the at-risk population and who engages in the intervention. General practitioners across five study sites recruited participants (aged 60-77 years, Cardiovascular Risk Factors, Aging, and Incidence of Dementia/CAIDE dementia risk score ≥ 9). Structured face-to-face interviews were conducted with eligible participants, including neuropsychological assessments. We analyzed group differences between (1) eligible vs. non-eligible participants, (2) participants vs. non-participants, and (3) between intervention groups. Of 1176 eligible participants, 146 (12.5%) dropped out before baseline; the study population was thus 1030 individuals. Non-participants did not differ from participants in key sociodemographic factors and dementia risk. Study participants were M = 69.0 (SD = 4.9) years old, and 52.1% were women. The average Montreal Cognitive Assessment/MoCA score was 24.5 (SD = 3.1), indicating a rather mildly cognitively impaired study population; however, 39.4% scored ≥ 26, thus being cognitively unimpaired. The bandwidth of cognitive states bears the interesting potential for differential trial outcome analyses. However, trial conduction is impacted by the COVID-19 pandemic, requiring adjustments to the study protocol with yet unclear methodological consequences.

[Gender-Specific Differences in the Utilization of Health Care Services in an Urban Population Sample]. / Geschlechterspezifische Inanspruchnahme von Gesundheitsleistungen in einer urbanen Erwachsenenpopulation.

AIM: This study explores gender-specific differences in the utilization of health care services in an urban population sample. METHOD: As part of the LIFE-ADULT-Study, 2244 individuals (19-79 years) filled out a questionnaire about their use of health care services during the past year. Information regarding the frequency of general and specialized practitioners consultation, medical advice from general practitioners and utilization of preventive and health promoting programs were analyzed. RESULTS: Women visited general practitioners or specialists and utilized prevention and health-promotion programs more often than men. No gender differences were found regarding the frequency of receiving medical advice from general practitioners. CONCLUSIONS: The results mainly replicate prior findings showing that women utilize health care services more frequently than men. However, these gender differences vary as a function of the indicator employed and should therefore be discussed differentially.

AgeWell.de - study protocol of a pragmatic multi-center cluster-randomized controlled prevention trial against cognitive decline in older primary care patients.

BACKGROUND: In the absence of treatment options, the WHO emphasizes the identification of effective prevention strategies as a key element to counteract the dementia epidemic. Regarding the complex nature of dementia, trials simultaneously targeting multiple risk factors should be particularly effective for prevention. So far, however, only few such multi-component trials have been launched, but yielding promising results. In Germany, comparable initiatives are lacking, and translation of these complex interventions into routine care was not yet done. Therefore, AgeWell.de will be conducted as the first multi-component prevention trial in Germany which is closely linked to the primary care setting. METHODS: AgeWell.de will be designed as a multi-centric, cluster-randomized controlled multi-component prevention trial. Participants will be older community-dwelling general practitioner (GP) patients (60-77 years; n = 1,152) with increased dementia risk according to CAIDE (Cardiovascular Risk Factors, Aging, and Incidence of Dementia) Dementia Risk Score. Recruitment will take place at 5 study sites across Germany. GP practices will be randomized to either intervention A (advanced) or B (basic). GPs will be blinded to their respective group assignment, as will be the statistician conducting the randomization. The multi-component intervention (A) includes nutritional counseling, physical activity, cognitive training, optimization of medication, management of vascular risk factors, social activity, and, if necessary, further specific interventions targeting grief and depression. Intervention B includes general health advice on the intervention components and GP treatment as usual. We hypothesize that over the 2-year follow-up period the intervention group A will benefit significantly from the intervention program in terms of preserved cognitive function/delayed cognitive decline (primary outcome), and other relevant (secondary) outcomes (e.g. quality of life, social activities, depressive symptomatology, cost-effectiveness). DISCUSSION: AgeWell.de will be the first multi-component trial targeting risk of cognitive decline in older adults in Germany. Compared to previous trials, AgeWell.de covers an even broader set of interventions suggested to be beneficial for the intended outcomes. The findings will add substantial knowledge on modifiable lifestyle factors to prevent or delay cognitive decline.

[Screening Instruments for the Detection of Male-Specific Symptoms of Unipolar Depression - A Critical Overview]. / Screeninginstrumente zur Erfassung von männerspezifischen Symptomen der unipolaren Depression ­ Ein kritischer Überblick.

BACKGROUND: Epidemiological studies have repeatedly pointed out gender differences in unipolar depression, whereas women have a 1.5 to 3 times higher risk of receiving a diagnosis. This however stands in sharp contrast with the 10 times higher suicide-rate of men, although depression is among the main risk-factors for suicide. Current literature therefore suspects an under-diagnosis of depression in men which is yet to be explained. While there is a vast body of literature covering the influence of gender norms, different symptomatology and use of health care services of men and women, systematic examinations of the role of diagnostic inventories or screening-instruments are currently not available. METHOD: A systematic literature search was conducted in order to provide an overview of current male-specific instruments for the detection of depression and to point out research gaps in the field of depression in men. RESULTS: Gender-specific inventories were used in 8 out of 122 relevant titles. Differences in the prevalence of unipolar depression tend to diminish or even disappear when gender-specific inventories are being used. DISCUSSION: Existing male-specific screening-instruments have only partly been validated and gender-specific instruments specifically designed for the detection of depression in primary care are currently lacking.
