    (Frontiers Media S.A, 2020-05) Röhr S; Löbner M; Gühne U; Heser K; Kleineidam L; Pentzek M; Fuchs A; Eisele M; Kaduszkiewicz H; König H-H; Brettschneider C; Wiese B; Mamone S; Weyerer S; Werle J; Bickel H; Weeg D; Maier W; Scherer M; Wagner M; Riedel-Heller SG
    Objectives: Social isolation is increasing in aging societies and several studies have shown a relation with worse cognition in old age. However, less is known about the association in the oldest-old (85+); the group that is at highest risk for both social isolation and dementia. Methods: Analyses were based on follow-up 5 to 9 of the longitudinal German study on aging, cognition, and dementia in primary care patients (AgeCoDe) and the study on needs, health service use, costs, and health-related quality of life in a large sample of oldest-old primary care patients (AgeQualiDe), a multi-center population-based prospective cohort study. Measurements included the Lubben Social Network Scale (LSNS-6), with a score below 12 indicating social isolation, as well as the Mini-Mental Status Examination (MMSE) as an indicator of cognitive function. Results: Dementia-free study participants (n = 942) were M = 86.4 (SD = 3.0) years old at observation onset, 68.2% were women. One third (32.3%) of them were socially isolated. Adjusted linear hybrid mixed effects models revealed significantly lower cognitive function in individuals with smaller social networks (β = 0.5, 95% CI = 0.3–0.7, p < .001). Moreover, changes in an individual’s social network size were significantly associated with cognitive changes over time (β = 0.2, 95% CI = 0.1–0.4, p = .003), indicating worse cognitive function with shrinking social networks. Conclusion: Social isolation is highly prevalent among oldest-old individuals, being a risk factor for decreases in cognitive function. Consequently, it is important to maintain a socially active lifestyle into very old age. Likewise, this calls for effective ways to prevent social isolation.

    Driving status and health-related quality of life among the oldest old: a population-based examination using data from the AgeCoDe–AgeQualiDe prospective cohort study
    (Springer Nature Switzerland AG, 2021-11) Hajek A; Brettschneider C; Lühmann D; van den Bussche H; Wiese B; Mamone S; Weyerer S; Werle J; Leve V; Fuchs A; Röhr S; Stein J; Bickel H; Mösch E; Heser K; Wagner M; Scherer M; Maier W; Riedel-Heller SG; Pentzek M; König H-H
    Background It is almost unknown whether the driving status is associated with HRQOL among individuals in highest age. Aims Based on a multicenter prospective cohort study, the objective of this study was to examine whether the driving status is associated with health-related quality of life (HRQOL) among the oldest old in Germany. Methods Cross-sectional data from follow-up wave 9 (n = 544) were derived from the “Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)” (AgeQualiDe). Average age was 90.3 years (± 2.7; 86 to 101 years). The current driver status (no; yes) was used in our analysis. The EuroQoL EQ-5D questionnaire was used to assess HRQOL in this study. Results Regression analysis showed that being a current driver was associated with the absence of problems in ‘self-care’ [OR 0.41 (95%-CI 0.17 to 0.98)], and ‘usual activities’ [OR 0.48 (0.26 to 0.90)], whereas it was not significantly associated with problems in ‘pain/discomfort’ [OR 0.82 (0.47 to 1.45)] and ‘anxiety/depression’ [OR 0.71 (0.36 to 1.39)]. Being a current driver was marginally significantly associated with the absence of problems in ‘mobility’ [OR 0.60 (0.34 to 1.06)]. While being a current driver was not associated with the EQ-VAS in the main model, it was positively associated with the driving status (β = 5.00, p < .05) when functional impairment was removed from the main model. Discussion Our findings provide first evidence for an association between driving status and HRQOL among the oldest old. Conclusions Future longitudinal studies are required to evaluate a possible causal relationship between driving status and HRQOL in very old individuals.

    Effects of APOE e4-allele and mental work demands on cognitive decline in old age: Results from the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe)
    (John Wiley and Sons Ltd, 2021-01) Rodriguez FS; Roehr S; Pabst A; Kleineidam L; Fuchs A; Wiese B; Lühmann D; Brettschneider C; Wolfsgruber S; Pentzek M; van den Bussche H; König H-H; Weyerer S; Werle J; Bickel H; Weeg D; Maier W; Scherer M; Wagner M; Riedel-Heller SG
    Objectives Previous studies have observed protective effects of high mental demands at work on cognitive functioning and dementia risk. However, it is unclear what types of demands drive this effect and whether this effect is subject to a person's genetic risk. We investigated to what extent eight different types of mental demands at work together with the APOE e4 allele, a major risk gene for late-onset Alzheimer's disease, affect cognitive functioning in late life. Methods/Design The population-based German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe, n = 2 154) followed cognitively healthy individuals aged 75 years and older in seven assessment waves. Cognitive functioning was assessed via the mini-mental status examination. Results Mixed-effects modeling (adjusted for education, gender, marital status, stroke, depression, and diabetes) indicated that participants who had an occupational history of working in jobs with high compared to low demands in “Language & Knowledge”, “Pattern detection”, “Information processing”, and “Service” had a slower cognitive decline. APOE e4-allele carriers had an accelerated cognitive decline, but this decline was significantly smaller if they had a medium compared to a low level of demands in contrast to non-carriers. Conclusions Our longitudinal observations suggest that cognitive decline could be slowed by an intellectually enriched lifestyle even in risk gene carriers. Fostering intellectual engagement throughout the life-course could be a key prevention initiative to promote better cognitive health in old age.

    GPs’ awareness of car driving among oldest patients: exploratory results from a primary care cohort
    (Royal College of General Practitioners, 2021-04) Leve V; Pentzek M; Fuchs A; Bickel H; Weeg D; Weyerer S; Werle J; König H-H; Hajek A; Lühmann D; van den Bussche H; Wiese B; Oey A; Heser K; Wagner M; Luppa M; Röhr S; Maier W; Scherer M; Kaduszkiewicz H; Riedel-Heller SG; for the AgeCoDe/AgeQualiDe Study Group
    Background Increasingly more very old people are active drivers. Sensory, motor and cognitive limitations, and medication can increase safety risks. Timely attention to driving safety in the patient–doctor relationship can promote patient-centred solutions. Aim To explore the following questions: do GPs know which patients drive a car? Is fitness to drive addressed with patients? Design & setting Cross-sectional data from patient interviews and GP survey in the ninth follow-up phase of a prospective primary care cohort (the German Study on Ageing, Cognition and Dementia in Primary Care Patients (AgeCoDe) and the Study on Needs, Health Service Use, Costs and Health-Related Quality of Life in a large sample of ‘oldest-old’ primary care patients (≥85 years; AgeQualiDe)) . Method The sample consisted of patients in the age group ≥85 years and their GPs. Independent reports were gathered on driving activity from the GP and the patient, and information was gained from GPs on whether driving ability was discussed with the patient. Statistical analyses included validity parameters and bivariate characterisation of subgroups (non-parametric significance tests, effect size). Results Self-reports of 553 patients were available (69.5% female; mean age 90.5 years; 15.9% drive a car). For 427 patients, GP data were also available: GPs recognised 67.1% correctly as drivers and 94.9% as non-drivers. GPs said that they had discussed fitness to drive with 32.1% of potentially driving patients. Among drivers who were not recognised and with whom driving had not been discussed, there were more patients with a low educational level. Conclusion The GP’s assessment of driving activity among very old patients showed moderate sensitivity and good specificity. Driving ability was seldom discussed. Asking an appropriate question during assessment could increase GPs’ awareness of older patients’ automobility.

    Lifestyle Aspects As A Predictor Of Pain Among Oldest-Old Primary Care Patients – A Longitudinal Cohort Study
    (Dove Medical Press, 2019-11) Mallon T; Eisele M; König H-H; Brettschneider C; Röhr S; Pabst A; Weyerer S; Werle J; Mösch E; Weeg D; Fuchs A; Pentzek M; Heser K; Wiese B; Kleineidam L; Wagner M; Riedel-Heller S; Maier W; Scherer M
    Purpose: Dealing with the high prevalence of pain among the oldest-old (+75) is becoming a major health issue. Therefore, the aim of the study was to uncover health-related lifestyle behaviors (HLB) and age-related comorbidities which may predict, influence and prevent pain in old age. Patients and methods: In this longitudinal cohort study, data were obtained initially from 3.327 individuals aged 75+ from over 138 general practitioners (GP) during structured clinical interviews in 2003. Nine follow-ups (FU) were assessed until 2017. Available data from 736 individuals scoring in FU3 and FU7 were included in this analysis. Data were assembled in an ambulatory setting at participant’s homes. Associations were tested using a linear regression model (model 1) and ordered logistic regression model (model 2). Results: Statistical analyses revealed increased likelihood to experience pain for participants with comorbidities such as peripheral arterial disease (PAD) (coef. 13.51, P>t = 0.00) or chronic back pain (CBP) (coef. 6.64, P>t = 0.003) or higher body mass index (BMI) (coef. 0.57, P>t = 0.015) and, female gender (coef. 6.00, SE 3.0, t = 2.02, P>t = 0.044). Participants with medium education and former smokers showed significantly lower pain rating (coef. −5.05, P>t = 0.026; coef. −5.27, P>t = 0.026). Suffering from chronic back pain (OR = 2.03), osteoarthritis (OR = 1.49) or depressive symptoms (OR = 1.10) raised the odds to experience impairments in daily living due to pain. Physical activity showed no significant results. Conclusion: Chronic conditions such as PAD, or CBP, female gender and higher BMI may increase the risk of experiencing more pain while successful smoking cessation can lower pain ratings at old age. Early and consistent support through GPs should be given to older patients in order to prevent pain at old age.

    Mild cognitive impairment and quality of life in the oldest old: a closer look
    (Springer Nature Switzerland AG, 2020-06) Hussenoeder FS; Conrad I; Roehr S; Fuchs A; Pentzek M; Bickel H; Moesch E; Weyerer S; Werle J; Wiese B; Mamone S; Brettschneider C; Heser K; Kleineidam L; Kaduszkiewicz H; Eisele M; Maier W; Wagner M; Scherer M; König H-H; Riedel-Heller SG
    Purpose Mild cognitive impairment (MCI) is a widespread phenomenon, especially affecting older individuals. We will analyze in how far MCI affects different facets of quality of life (QOL). Methods We used a sample of 903 participants (110 with MCI) from the fifth follow-up of the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe), a prospective longitudinal study, to analyze the effects of MCI on different facets of the WHOQOL-OLD. We controlled for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see, and hear. Results Univariate analyses showed that individuals with MCI exhibited lower QOL with regard to the facets autonomy; past, present, and future activities; social participation; and intimacy, but less fears related to death and dying. No significant difference was shown with regard to the facet sensory abilities. In multivariate analyses controlling for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see and hear, MCI-status was significantly associated with QOL in the facet autonomy. Conclusion Effects of MCI go beyond cognition and significantly impact the lives of those affected. Further research and practice will benefit from utilizing specific facets of QOL rather than a total score.

    Prevalence of Anxiety Symptoms and Their Association With Loss Experience in a Large Cohort Sample of the Oldest-Old. Results of the AgeCoDe/AgeQualiDe Study
    (Frontiers Media S.A, 2019) Welzel FD; Stein J; Röhr S; Fuchs A; Pentzek M; Mösch E; Bickel H; Weyerer S; Werle J; Wiese B; Oey A; Hajek A; König H-H; Heser K; Keineidam L; van den Bussche H; van der Leeden C; Maier W; Scherer M; Wagner M; Riedel-Heller SG
    Background: Anxiety in adults is a common mental health problem. However, studies on anxiety in the oldest-old are lacking. We sought to identify the age- and gender-specific prevalence of anxiety symptoms in a large sample of general practice patients. Furthermore, we investigated relevant associations of anxiety specifically with respect to recent experience of loss. Methods: Based on the German Study on Ageing, Cognition and Dementia in general practice patients, a sample of 897 patients aged 82 years and older was assessed. Anxiety was assessed using the short form of the Geriatric Anxiety Inventory (GAI-SF). For the assessment of loss, patients were asked whether there were cases of death in their closer social environment since the last assessment. Descriptive and logistic regression analyses were run. Results: Of the oldest-old individuals (aged 82+ years, mean age: 86.8), 14.5% (95% CI 12.4–16.8) suffered from anxiety symptoms. Highest prevalence rates were found for 82- to 85-year-old women (17.2%, 95% CI 12.6–22.1) and for 86- to 90-year-old patients (both sexes) in general (15.9%, 95% CI 12.6–19.2). Older individuals who experienced cases of death in their close social environment within the last 18 months had almost twice the odds [odds ratio (OR) 1.91, 95% confidence interval (CI) 1.15–3.17] of reporting anxiety compared to those without a recent loss. As expected, depression and impaired cognitive status were associated with the presence of anxiety symptoms. No relation was found between social network, gender, age, frailty, or physical illness and anxiety in regression analysis. Conclusions: This study provides for the first time age- and gender-specific prevalence rates of anxiety symptoms and associated risk factors among a large population-based sample of oldest-old primary care attenders. Anxiety is highly prevalent in individuals aged 82 years and older. Depression, impaired cognitive status, and recent experience of loss are associated with late-life anxiety. Our findings support the idea that recent experience of loss should be taken seriously in the context of clinical practice with respect to diagnosing and treating anxiety in old age.

    Prevalence of pain and its associated factors among the oldest-olds in different care settings – results of the AgeQualiDe study
    (BioMed Central Ltd, 2018) Mallon T; Ernst A; Brettschneider C; König H-H; Luck T; Röhr S; Weyerer S; Werle J; Mösch E; Weeg D; Fuchs A; Pentzek M; Kleineidam L; Heser K; Riedel-Heller S; Maier W; Wiese B; Scherer M; AgeCoDe & AgeQualiDe study group
    Background The prevalence of pain is very common in the oldest age group. Managing pain successfully is a key topic in primary care, especially within the ageing population. Different care settings might have an impact on the prevalence of pain and everyday life. Methods Participants from the German longitudinal cohort study on Needs, Health Service Use, Costs and Health-related Quality of Life in a large Sample of Oldest-old Primary Care Patients (85+) (AgeQualiDe) were asked to rate their severity of pain as well as the impairment with daily activities. Besides gender, age, education, BMI and use of analgesics we focused on the current housing situation and on cognitive state. Associations of the dependent measures were tested using four ordinal logistic regression models. Model 1 and 4 consisted of the overall sample, model 2 and 3 were divided according to no cognitive impairment (NCI) and mild cognitive impairment (MCI). Results Results show a decline in pain at very old age but nonetheless a high prevalence among the 85+ year olds. Sixty-three per cent of the participants report mild to severe pain and 69% of the participants mild to extreme impairment due to pain with daily activities. Use of analgesics, depression and living at home with care support are significantly associated with higher and male gender with lower pain ratings. Conclusions Sufficient pain management among the oldest age group is inevitable. Outpatient care settings are at risk of overlooking pain. Therefore focus should be set on pain management in these settings.

    Social Isolation and Incident Dementia in the Oldest-Old—A Competing Risk Analysis
    (Frontiers Media S.A, 2022-06) Grothe J; Röhr S; Luppa M; Pabst A; Kleineidam L; Heser K; Fuchs A; Pentzek M; Oey A; Wiese B; Lühmann D; van den Bussche H; Weyerer S; Werle J; Weeg D; Bickel H; Scherer M; König H-H; Hajek A; Wagner M; Riedel-Heller SG
    Purpose: Social isolation is considered a risk factor for dementia. However, less is known about social isolation and dementia with respect to competing risk of death, particularly in the oldest-old, who are at highest risk for social isolation, dementia and mortality. Therefore, we aimed to examine these associations in a sample of oldest-old individuals. Methods: Analyses were based on follow-up (FU) 5–9 of the longitudinal German study AgeCoDe/AgeQualiDe. Social isolation was assessed using the short form of the Lubben Social Network Scale (LSNS-6), with a score ≤ 12 indicating social isolation. Structured interviews were used to identify dementia cases. Competing risk analysis based on the Fine-Gray model was conducted to test the association between social isolation and incident dementia. Results: Excluding participants with prevalent dementia, n = 1,161 individuals were included. Their mean age was 86.6 (SD = 3.1) years and 67.0% were female. The prevalence of social isolation was 34.7% at FU 5, 9.7% developed dementia and 36.0% died during a mean FU time of 4.3 (SD = 0.4) years. Adjusting for covariates and cumulative mortality risk, social isolation was not significantly associated with incident dementia; neither in the total sample (sHR: 1.07, 95%CI 0.65-1.76, p = 0.80), nor if stratified by sex (men: sHR: 0.71, 95%CI 0.28-1.83, p = 0.48; women: sHR: 1.39, 95%CI 0.77-2.51, p = 0.27). Conclusion: In contrast to the findings of previous studies, we did not find an association between social isolation and incident dementia in the oldest-old. However, our analysis took into account the competing risk of death and the FU period was rather short. Future studies, especially with longer FU periods and more comprehensive assessment of qualitative social network characteristics (e.g., loneliness and satisfaction with social relationships) may be useful for clarification.
