Is loneliness associated with cancellation of medical appointments during the COVID-19 pandemic? Evidence from the Hamburg City Health Study (HCHS).

BACKGROUND: The COVID-19 pandemic engendered numerous societal and economic challenges in addition to health-related concerns. Maintenance of healthcare utilization assumed immense significance during this period. However, few studies have examined the association between loneliness and cancelled medical appointments during the COVID-19 pandemic. This study aimed to examine whether medical appointments are less likely to be cancelled with increased loneliness during a pandemic. We analyzed the association between loneliness and both patient- and provider-initiated appointment cancellations. METHODS: Cross-sectional data from the Hamburg City Health Study (HCHS) were collected during April 2020-November 2021. The analytical sample included 1,840 participants with an average age of 55.1 years (standard deviation: 6.5, range 45-76 years). Medical appointments cancelled by individuals-medical appointments in general, and GP, specialist, and dentist appointments-and appointments cancelled by healthcare providers served as outcome measures. Loneliness was quantified using a single item ranging from 0 to 10. Accordingly, we created empirical loneliness tertiles. Covariates were selected based on the Andersen model. Several penalized maximum likelihood logistic regressions were utilized to examine the association between loneliness and cancellation of medical appointments during the COVID-19 pandemic. RESULTS: The penalized maximum likelihood logistic regressions showed that, compared to individuals in the lowest loneliness tertiles, individuals in the other two tertiles reported a higher chance of medical appointments cancellation by individuals, particularly driven by cancelled GP appointments. Except for age and sex, none of the covariates were comparably associated with the outcomes. When appointments cancelled by healthcare providers served as outcomes, only a higher number of chronic conditions was significantly positively associated with it. CONCLUSIONS: Individuals scoring higher in loneliness had a greater chance of cancelling medical (particularly GP) appointments. This may contribute to a potential cascade of loneliness and skipped medical appointments in the future, resulting in adverse health outcomes over the medium-to-long term. Future research should examine whether lonely people are more likely to lack the social motivation to visit the doctor.

Physical activity in adults with and without rheumatoid arthritis: cross-sectional results from the Survey of Health, Ageing and Retirement in Europe (SHARE).

OBJECTIVE: Studies examining habitual physical activity levels and patterns in adults with rheumatoid arthritis (RA) using raw data from modern accelerometers are lacking. We aimed (i) to examine physical activity levels and patterns in adults with RA in their familiar environment, and (ii) to investigate whether physical activity levels differ throughout the day. METHOD: Data were taken from Wave 8 of the Survey of Health, Ageing and Retirement in Europe, including N = 607 men and women who wore a triaxial accelerometer and had adequate information for RA and accelerometry data summarized as Euclidean norm minus one (ENMO, mg). Growth-curve models and simple contrast analysis were used to examine the effect of RA on daily patterns of physical activity levels, including mean total ENMO in mg, mean minutes of light-intensity physical activity (ENMO values ≥ 25 mg and ≤ 75 mg), and moderate-to-vigorous-intensity physical activity (ENMO values > 75 mg). RESULTS: Total physical activity averaged throughout the day was 25.0 and 28.6 mg for respondents with and without RA, respectively. Respondents with RA spent more time in light-intensity physical activity throughout the day (p < 0.001), but less time in moderate-to-vigorous-intensity physical activity between 4 am and 11 pm (p < 0.001) than respondents without RA. CONCLUSION: Adults with RA were less physically active than adults without RA. However, there were no diurnal differences in physical activity.

Fear of war and mental health in Germany.

PURPOSE: The objective of this study was to clarify the association between fear of war (both conventional war and nuclear war) and mental health (in terms of probable depression and probable anxiety). METHODS: Data were used from the general adult population in Germany (n = 3091 individuals; 15th March-21st March 2022). Probable depression and probable anxiety were both quantified using validated tools (PHQ-9/GAD-7). Multiple logistic regressions were used, adjusting for several sociodemographic, lifestyle-related and health-related factors. RESULTS: In total, 23.1% of the individuals had probable depression and 16.0% of the individuals had probable anxiety. Multiple logistic regression showed that the likelihood of probable depression was positively associated with fear of a conventional war (OR 1.25, 95% CI 1.14-1.37). Furthermore, it was associated with fear of a nuclear war (OR 1.22, 95% CI 1.12-1.33). Additionally, regressions showed that the likelihood of probable anxiety was positively associated with fear of a conventional war (OR 1.66, 95% CI 1.49-1.86). Moreover, it was associated with fear of a nuclear war (OR 1.54, 95% CI 1.39-1.71). CONCLUSIONS: Our findings stress the importance of fear of war for mental health in the general adult population in Germany. Upcoming research in this area is necessary.

Climate anxiety in Germany.

OBJECTIVES: This study aimed to clarify the level and the correlates of climate anxiety in Germany. STUDY DESIGN: This was a quota-based online survey. METHODS: We used data collected in mid-March 2022 from a sample of the general adult population (n = 3091 individuals aged 18-74 years; March 2022). Climate anxiety was quantified using the Climate Anxiety Scale (ranging from 1 to 7, with higher scores corresponding to higher levels of climate anxiety). RESULTS: The average level of climate anxiety in Germany was 2.0 (standard deviation [SD]: 1.2). It differed between subgroups (e.g. individuals aged 18-29 years: 2.4, SD: 1.3; individuals aged 65-74 years: 1.8, SD: 1.0). Log-linear regressions showed that climate anxiety was higher among younger individuals (ß = -0.005, P < .001), full-time employed individuals (compared with retired individuals, ß = 0.07, P < .01), individuals without chronic conditions (compared with individuals with at least one chronic conditions, ß = -0.08, P < .001), individuals already vaccinated against COVID-19 (compared with individuals not vaccinated against COVID-19, ß = 0.10, P < .001), individuals with higher levels of coronavirus anxiety (ß = 0.06, P < .001), and individuals with greater fear of a conventional war (ß = 0.09, P < .001). CONCLUSIONS: Our study showed a rather low level of climate anxiety. It also revealed some correlates of greater climate anxiety such as higher levels of coronavirus anxiety or greater fear of war. Knowledge about the correlates may assist in addressing individuals at risk for high levels of climate anxiety.

Oral Health, Loneliness and Social Isolation. A Systematic Review and Meta-Analysis.

OBJECTIVES: Thus far, some empirical studies have investigated the association between oral health and loneliness as well as social isolation. However, a systematic review and meta-analysis is lacking synthesizing this evidence. Hence, our purpose was to close this knowledge gap. DESIGN: Systematic review and meta-analysis. SETTING AND PARTICIPANTS: Observational studies examining the association between oral health and loneliness or social isolation were included. Disease-specific samples were excluded. METHODS: We searched three electronic databases (PubMed, PsycINFO, CINAHL), and did an additional hand search. Data extraction covered methods, sample characteristics and main findings. To evaluate study quality/risk of bias, the NIH tool was used. Study selection, data extraction and assessment of study quality were each conducted by two reviewers. RESULTS: Seven studies were included in our current work. Several cross-sectional studies and one longitudinal study reported an association between poorer oral health and higher loneliness as well as higher social isolation. The quality of the studies was mostly fair, with two studies of high quality. The pooled OR was 1.47 (95% CI: 1.24-1.75) among the studies with adult samples. CONCLUSION: Most of the included studies demonstrated an association between oral health and loneliness or social isolation. There is a lack of high quality studies on these associations; in particular, future studies should use longitudinal data to clarify the directionality between oral health and loneliness or social isolation.

Factors associated with postponed health checkups during the COVID-19 pandemic in Germany.

OBJECTIVES: The COVID-19 pandemic has serious social, economic and health consequences. Particularly in these times, it is important to maintain individual health. Therefore, it is important to take part in routine health checkups. Consequently, our objective was to describe the frequency and to identify the determinants of postponed routine health checkups. STUDY DESIGN: Cross-sectional data from the nationally representative online-survey "COVID-19 Snapshot Monitoring in Germany (COSMO)" was used (wave 17; July 2020). METHODS: In sum, 974 individuals were included in our analytical sample (average age was 45.9 years, SD: 16.5, 18-74 years). Postponed routine health checkups (yes or no) since March 2020 due to the COVID-19 pandemic were assessed. RESULTS: More than 16% of the individuals reported postponed routine health checkups in the past few months due to the COVID-19 pandemic. Particularly, individuals aged 30-49 years had postponed health checkups (21%). The probability of postponed health checkups was positively associated with the presence of chronic diseases (odds ratio [OR]: 1.68, 95% confidence interval [CI]: 1.15-2.47), higher affect regarding COVID-19 (OR: 1.44, 95%-CI: 1.16-1.78), and higher presumed severity of COVID-19 (OR: 1.17, 95%-CI: 1.01-1.35), whereas the outcome measure was not associated with socioeconomic factors. Data showed that a sizeable part (about one of six individuals) of the population reported postponed routine health checkups due to the COVID-19 pandemic between March and July 2020. CONCLUSIONS: Postponed checkups should not be neglected during the COVID-19 pandemic. Individuals at risk for postponed health checkups should be appropriately addressed.

Determinants of health-related quality of life among homeless individuals during the COVID-19 pandemic.

OBJECTIVE: To clarify which variables are associated with the health-related quality of life (HRQoL) among homeless individuals during the COVID-19 pandemic. STUDY DESIGN: Cross-sectional research. METHODS: Data were taken from the Hamburg survey of homeless individuals (n = 151). HRQoL was assessed using the EQ-5D tool. More precisely, the EQ-5D-5L questionnaire was used to quantify problems in five health dimensions (i.e. mobility, self-care, usually activities, pain/discomfort, anxiety/depression), and its visual analog scale (EQ-VAS) was used to record the according self-rated health status. Explanatory variables include sex, age, education, marital status, country of origin, health insurance, and chronic alcohol consumption. RESULTS: With regard to HRQoL, most frequently, problems were reported as pain/discomfort (47.3%), followed by anxiety/depression (32.4%), mobility (29.7%), usual activities (20.7%) and self-care (4.6%). The mean EQ-VAS score was 75.34 (SD 22.23; range 1-100), and the mean EQ-5D-5L index was 0.84 (SD 0.23; range 0.32-1). Regressions showed increasing problems in mobility and self-care with higher age, whereas EQ-VAS was positively associated with younger age. Furthermore, EQ-5D-5L index was positively associated with younger age and higher education. Summarized, among this cohort, a higher age is associated with a lower HRQoL. CONCLUSION: Remarkably high EQ-VAS values and rather few problems in the five dimensions investigated here were reported among the homeless individuals during the COVID-19 pandemic particularly compared with the general population. Moreover, study findings particularly stress the link between higher age and lower HRQoL among homeless individuals. This knowledge is important to address homeless individuals at risk of poor HRQoL. Longitudinal studies are required to confirm the given findings.

Grief and loss in old age: Exploration of the association between grief and depression.

BACKGROUND: The proportion of older adults is increasing due to demographic changes. Depression belongs to the most common mental disorders in late life. The loss of an emotionally significant person is a risk factor for the development of depression. The aim of this study is to analyze the association between depression and grief burden resulting from loss. Based on prior evidence, we examined loneliness as a possible mediator and social support as possible moderator of this association. METHODS: The cross-sectional analyses are based on a sample (N = 863) of study participants aged 75+ (M = 81.4 years, SD = 4.4, 62.2% female) with loss experience deriving from the multicenter prospective German cohort study AgeMooDe. Regression analyses (moderated mediation) were performed. RESULTS: With increasing age (ß = 0.10, p = .005) and grief burden (ß = 0.33, p <. 001) depression severity increased. There was an indirect mediating effect of loneliness on the correlation of grief burden and depression (b = 0.04, CI [0.03, 0.05]), but no moderating effect of social support on the correlation of grief burden and loneliness. People living alone had a significantly higher risk of depression, increased loneliness and lack of social support. LIMITATIONS: Assessments were based on self-reporting and recorded dimensionally. The cross-sectional design limits conclusions about directions and causality of associations. Sampling bias cannot be completely excluded. CONCLUSION: The study provides empirical evidence and a better understanding of the association between grief and depression among the very old and the mediating role of loneliness.

Public stigma towards informal caregiving in Germany: a descriptive study.

OBJECTIVES: This study aims to investigate the public stigma towards informal caregivers of individuals aged 65 years and older in the German population. METHOD: In an Online-Survey 1038 participants (18 years and older and living in Germany) were sampled using a quota-system based on the German micro census data. To assess public stigma towards informal caregiving for individuals aged 65 years and older, three aspects of stigma were assessed: 1) emotional reactions (adapted Emotional Reaction to Mental Illness Scale), 2) behavioral reactions (adapted Social Distance Scale), and 3) cognitive reactions (newly developed List of Cognitions regarding informal caregiving). Exploratory and confirmatory factor analyses were conducted for the development and adaptation of the three instruments, and their composite reliability is provided. RESULTS: Emotional reactions in terms of devaluing feelings and feelings of misery were low, while appreciative feelings were neither low nor high. Reported social distance was low. Agreement with cognitions towards informal care in terms of devaluing and accusative cognitions was on average low, but high regarding appreciative cognitions. CONCLUSION: The results show that there is stigma towards informal caregiving for older individuals (65 years and older) in terms of emotional reactions, cognitions and social distance, although the magnitude of this stigma seems to be small. Knowledge regarding the occurrence and magnitude of stigma, as well as the processes that underlie this, is needed to prevent stigmatization and its negative outcomes, or at the very least, to enable the development of support for the affected individuals.

Prevalence and determinants of dental visits among older adults: findings of a nationally representative longitudinal study.

BACKGROUND: The first aim was to present descriptive data on the frequency of dental visits among older adults in Germany. The second aim was to identify the determinants of the number of dental visits using a longitudinal approach. METHODS: Longitudinal data were derived from the German Ageing Survey, which is a nationally representative sample of community-dwelling individuals ≥40 years in Germany. The frequency of dental visits in the past 12 months was recorded in the years 2002, 2008 and 2011. In order to control for time-constant unobserved heterogeneity, Poisson fixed effects regressions were used. RESULTS: While the mean number of dental visits was 2.3 (SD: 2.0) in 2002, it was 2.0 (SD: 1.7) in 2008 and 2.1 (SD: 1.7) in 2011. The frequency of dental visits declined with age (total sample and women), transitions from normal weight to overweight (total sample), changes from divorced/widowed/single/married, living separated from spouse to 'married, living together with spouse' in women and with a decrease in the number of physical illnesses (total sample and men). CONCLUSIONS: The frequency of dental visits declines with age in older adults. While some of the determinants of frequency are non-modifiable (e.g., ageing and worsening of general health), others are modifiable (e.g., change in weight category).

Association of generalized anxiety symptoms and panic with health care costs in older age-Results from the ESTHER cohort study.

BACKGROUND: Little is known specifically about the association between generalized anxiety symptoms or panic and health care costs in older age. The aim of this study was to examine the association between generalized anxiety symptoms, panic and health care costs in people aged 65 and over. METHODS: Cross-sectional data from the 8-year follow-up of a large, prospective cohort study, the ESTHER study, was used. Individuals aged 65 and over, who participated in the study's home assessment, were included in this analysis (n = 2348). Total and sectoral costs were analyzed as a function of either anxiety symptoms, probable panic disorder, or a panic attack, while controlling for selected covariates, using Two Part and Generalized Linear Models. Covariates were chosen based on Andersen's Behavioral Model of Health Care Use. RESULTS: There was no significant association between either of the anxiety or panic measures and total health care costs. Stratified by health care sectors, only the occurrence of a panic attack was significantly associated with incurring costs for outpatient non-physician services (OR: 1.99; 95% CI: 1.15-3.45) and inpatient services (OR: 2.14; 95% CI: 1.07-4.28). Other illness-related factors, such as comorbidities and depressive symptoms, were associated with health care costs in several models. LIMITATIONS: This was a cross-sectional study relying on self-reported data. CONCLUSION: This study points to an association between a panic attack and sector-specific health care costs in people aged 65 and over. Further research, especially using longitudinal data, is needed.

The role of optimism in the relationship between job stress and depressive symptoms. Longitudinal findings from the German Ageing Survey.

BACKGROUND: The aim of the present study was to investigate the effect of job stress on depressive symptoms and whether optimism moderates this relationship longitudinally. Data were used from 2002 until 2014 (wave 2 to 5) of the German Ageing Survey. The sample consists of community-dwelling individuals living in Germany aged from 40 to 95 years (7086 observations in fixed effects regression analysis). METHODS: A self-report questionnaire was used to measure depressive symptoms (Center for Epidemiologic Studies Depression Scale), job stress (scale 1 to 5) and optimism (Optimism Scale of Brandtstaedter & Wentura). RESULTS: Adjusting for potential confounders, fixed effects regression analysis revealed that an increase in job stress was associated with an increase in depressive symptoms, whereas an increase in optimism was associated with a decrease in depressive symptoms. Optimism significantly moderated the relation between job stress and depressive symptoms. LIMITATIONS: The possibility of a small sample selection bias cannot be dismissed. CONCLUSIONS: The present study highlights the moderating role of optimism in the relation between job stress and depressive symptoms longitudinally. Thus, efforts to increase optimism in individuals might be beneficial in reducing depressive symptoms among individuals with high job stress.

Longitudinal Analysis of Outpatient Physician Visits in the Oldest Old: Results of the AgeQualiDe Prospective Cohort Study.

OBJECTIVES: The aim of this study was to identify determinants of outpatient health care utilization among the oldest old in Germany longitudinally. DESIGN: Multicenter prospective 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). SETTING: Individuals in very old age were recruited via GP offices at six study centers in Germany. The course of outpatient health care was observed over 10 months (two waves). PARTICIPANTS: Primary care patients aged 85 years and over (at baseline: n=861, with mean age of 89.0 years±2.9 years; 85-100 years). MEASUREMENTS: Self-reported numbers of outpatient visits to general practitioners (GP) and specialists in the past three months were used as dependent variables. Widely used scales were used to quantify explanatory variables (e.g., Geriatric Depression Scale, Instrumental Activities of Daily Living Scale, or Global Deterioration Scale). RESULTS: Fixed effects regressions showed that increases in GP visits were associated with increases in cognitive impairment, whereas they were not associated with changes in marital status, functional decline, increasing number of chronic conditions, increasing age, and changes in social network. Increases in specialist visits were not associated with changes in the explanatory variables. CONCLUSION: Our findings underline the importance of cognitive impairment for GP visits. Creating strategies to postpone cognitive decline might be beneficial for the health care system.

Preferences for home- and community-based long-term care services in Germany: a discrete choice experiment.

BACKGROUND: Most people prefer to "age in place" and to remain in their homes for as long as possible even in case they require long-term care. While informal care is projected to decrease in Germany, the use of home- and community-based services (HCBS) can be expected to increase in the future. Preference-based data on aspects of HCBS is needed to optimize person-centered care. OBJECTIVE: To investigate preferences for home- and community-based long-term care services packages. DESIGN: Discrete choice experiment conducted in mailed survey. SETTING AND PARTICIPANTS: Randomly selected sample of the general population aged 45-64 years in Germany (n = 1.209). MAIN VARIABLES STUDIED: Preferences and marginal willingness to pay (WTP) for HCBS were assessed with respect to five HCBS attributes (with 2-4 levels): care time per day, service level of the HCBS provider, quality of care, number of different caregivers per month, co-payment. RESULTS: Quality of care was the most important attribute to respondents and small teams of regular caregivers (1-2) were preferred over larger teams. Yet, an extended range of services of the HCBS provider was not preferred over a more narrow range. WTP per hour of HCBS was €8.98. CONCLUSIONS: Our findings on preferences for HCBS in the general population in Germany add to the growing international evidence of preferences for LTC. In light of the great importance of high care quality to respondents, reimbursement for services by HCBS providers could be more strongly linked to the quality of services.

[Informal care for dementia according to type of service]. / Informelle Pflege bei Demenz nach Leistungsarten.

BACKGROUND: Dementia is a major challenge for society and its impact will grow in the future. Informal care is an essential part of dementia care. Previous studies considered informal care as a whole and not by its components. OBJECTIVE: We aimed to assess the degree of association between specific informal care services and dementia. MATERIAL AND METHODS: This analysis is based on data from the seventh wave of the AgeCoDe/AgeQualiDe study. Dementia was diagnosed based on the DSM-IV criteria. Severity of dementia was assessed and categorized by means of the Clinical Dementia Rating and eight individual informal care services were considered. Logistic regression models were used to assess associations. RESULTS: Of the 864 participants 18% suffered from dementia (very mild: 4%; mild: 6%; moderate: 5%; severe: 3%). All informal care services were significantly associated with dementia, with an emphasis on "supervision", "regulation of financial matters" and "assistance in the intake of medication". Considering different degrees of dementia severity, similar results arose from the analyses. All three aforementioned services showed a pronounced association with all degrees of dementia severity, except for supervision and very mild dementia. CONCLUSION: The provision of all types of informal care services is associated with dementia. The association is pronounced for services that can be more easily integrated into the daily routines of the informal caregiver. Policy makers who plan to integrate informal care into the general care arrangements for dementia should consider this.

[Morbidity Differences by Health Insurance Status in Old Age]. / Unterschiede in der Morbidität nach Krankenversichertenstatus im Alter.

BACKGROUND: Morbidity differences between older members of private and statutory health insurance Germany have rarely been examined. Thus, we aimed at determining these differences in old age. METHODS: This study used data from 2 follow-up waves with a 3-year interval from a population-based prospective cohort study (ESTHER study) in Saarland, Germany. Morbidity was assessed by participants' GPs using a generic instrument (Cumulative Illness Rating Scale for Geriatrics). The between estimator was used which exclusively quantifies inter-individual variation. Adjusting for sex and age, we investigated the association between health insurance and morbidity in the main model. In additional models, we adjusted incrementally for the effect of education, family status and income. RESULTS: Regression models not adjusting for income showed that members of private health insurance had a lower morbidity score than members of statutory health insurance. This effect is considerably lower in models adjusting for income, but remained statistically significant (except for men). CONCLUSION: Observed differences in morbidity between older members of private and statutory health insurance can partly be explained by income differences. Thus, our findings highlight the role of model specification in determining the relation between morbidity and health insurance.

The longitudinal association between informal caregiving and body mass index in the second half of life: findings of the German Ageing Survey.

OBJECTIVE: We aimed to investigate the relation between informal caregiving and body mass index (BMI) longitudinally. STUDY DESIGN: The data were drawn from wave 2 (2002) to wave 5 (2014) of the German Ageing Survey. This is a representative sample of the community-dwelling population aged 40 years and above in Germany. METHODS: Self-rated BMI was used. Individuals were asked whether they provide informal care on a regular basis. Adjusting for employment status, age, marital status, morbidity and depressive symptoms, fixed effects regressions were used. RESULTS: The fixed effects regressions showed that the onset of informal caregiving was not associated with changes in BMI in the total sample and in women, whereas the onset of informal caregiving was associated with increasing BMI in men (ß = 0.15, P < 0.05). In addition, an increase in BMI was positively associated with ageing, an increase in morbidity and a decrease in frequency of sports activities in the total sample and in both sexes. CONCLUSIONS: Our findings stress the longitudinal relation between informal caregiving and BMI in men. Consequently, it might be helpful to generate weight management strategies specifically designed for male informal caregivers.

Does Visual Impairment Affect Social Ties in Late Life? Findings of a Multicenter Prospective Cohort Study in Germany.

OBJECTIVE: To investigate how visual impairment affects social ties in late life longitudinally. DESIGN: Population-based prospective cohort study. SETTING: Individuals in old age were recruited via general practitioners' offices (at six study centers) in Germany. They were interviewed every 18 months. PARTICIPANTS: Individuals aged 75 years and above at baseline. Follow-up wave 2 (36 months after baseline, n=2,443) and wave 4 (72 months after baseline, n=1,618) were used for the analyses presented here. MEASUREMENTS: Social ties were assessed using the 14-item form of the questionnaire for social support (F-SozU K-14). Visual impairment was self-rated on a three level Likert scale (no impairment, mild visual impairment, or severe/profound visual impairment). RESULTS: Adjusting for sociodemographic factors, hearing impairment and comorbidity, fixed effects regressions revealed that the onset of mild visual impairment decreased the social support score, in particular the emotional support score. Additionally, the onset of mild hearing impairment decreased the social support score in men. Moreover, increasing age decreased the social support score in the total sample and in both sexes. Loss of spouse and increasing comorbidity did not affect the social support score. CONCLUSION: Our results highlight the importance of visual impairment for social ties in late life. Consequently, appropriate strategies in order to delay visual impairment might help to maintain social ties in old age.

Factors Affecting Functional Impairment among Elderly Germans - Results of a Longitudinal Study.

OBJECTIVE: To investigate causal factors of functional impairment in old age in a longitudinal approach. DESIGN: A population-based prospective cohort study. SETTING: Elderly individuals were recruited via GP offices at six study centers in Germany. They were observed every 1.5 years over six waves. PARTICIPANTS: Three thousand two hundred fifty-six people aged 75 years and older at baseline. MEASUREMENTS: Functional impairment was quantified by the Lawton and Brody Instrumental Activities of Daily Living scale (IADL) and the Barthel-Index (BI). RESULTS: Fixed effects regressions revealed that functional impairment (IADL; BI) increased significantly with ageing (ß=-.2; ß=-1.1), loss of a spouse (ß= .5; ß=-3.1), not living alone in private household (ß=-1.2; ß=-5.5), depression (solely significant for IADL: ß= .6) and dementia (ß=-2.3; ß=-18.2). The comorbidity score did not affect functional impairment. CONCLUSION: Our findings underline the relevance of changes in sociodemographic variables as well as the occurrence of depression or dementia for functional impairment. While several of these causal factors for functional decline in the oldest old are inevitable, some may not be, such as depression. Therefore, developing interventional strategies to prevent depression might be a fruitful approach in order to delay functional impairment in old age.

[Longitudinal Predictors of the Need for Care]. / Einflussfaktoren auf die Pflegebedürftigkeit im Längsschnitt.

Background: Little is known about the longitudinal predictors of the need for care in old age. However, the knowledge of these factors is important for developing strategies for prevention or delay the need for care. Thus, we aimed at investigating the factors affecting the need for care in old age. Methods: In this population-based prospective cohort study (AgeCoDe, with n=3 217 individuals aged 75 years and above at baseline), the need for care was observed over 4.5 years. The need for care was quantified by the care level defined by the German Law (§ 15 SGB XI). Longitudinal predictors (sociodemographic variables, impairment in mobility/hearing/vision, dementia and depression) of the need for care were examined by using Random Effects Logit regressions. Results: Longitudinal regression analysis revealed that the probability of the need for care significantly increased with the occurrence of dementia (OR: 48.2), mobility impairments (aggravated walking, OR: 26.4; disability of walking, OR: 747.9) and age (e. g. 90 years and above vs.<80 years, OR: 32.3). The influence of family status, living conditions, visual impairment and depression on need for care was markedly smaller, and the effect of hearing impairments did not achieve statistical significance. Conclusion: In order to prevent or delay the need for care in old age, treatments should aim at preserving mobility and cognition. Due to demographic ageing, developing such programs is of major importance for health policy.
