Age of Alzheimer's disease diagnosis in people with Down syndrome and associated factors: Results from the Horizon 21 European Down syndrome consortium.

INTRODUCTION: People with Down syndrome (DS) have high risk of developing Alzheimer's disease (AD). This study examined mean ages of AD diagnosis and associations with co-occurring conditions among adults with DS from five European countries. METHODS: Data from 1335 people with DS from the Horizon 21 European DS Consortium were used for the analysis. RESULTS: Mean ages of AD diagnosis ranged between 51.4 (SD 7.0) years (United Kingdom) and 55.6 (SD 6.8) years (France). Sleep-related and mental health problems were associated with earlier age of AD diagnosis. The higher number of co-occurring conditions the more likely the person with DS is diagnosed with AD at an earlier age. DISCUSSION: Mean age of AD diagnosis in DS was relatively consistent across countries. However, co-occurring conditions varied and impacted on age of diagnosis, suggesting that improvements can be made in diagnosing and managing these conditions to delay onset of AD in DS. HIGHLIGHTS: Mean age of AD diagnosis was relatively consistent between countries Sleep problems and mental health problems were associated with earlier age of AD diagnosis APOE ε4 carriers were diagnosed with AD at an earlier age compared to non-carriers Number of co-occurring conditions was associated with earlier age of AD diagnosis No differences between level of intellectual disability and mean age of AD diagnosis.

Time trends in loneliness from 1984 to 2019 among 27,032 older adults in Norway: A HUNT study.

The aging population and increasing evidence of the detrimental health impacts of loneliness emphasize the importance of studying and predicting changes in loneliness prevalence among older adults. To understand and project changes in loneliness over time, we examined 35-year trends in adults aged 70 and older, considering factors such as sex, age, and living situation. Cross-sectional data from 27,032 home-dwelling adults aged 70 years and older who participated in at least one of the four Norwegian HUNT surveys from 1984 to 2019, and Norwegian population data from Statistics Norway were used for the analyses. Loneliness was self-reported, and the prevalence of loneliness was standardized to the Norwegian population at the survey year by age and sex. The results showed that the prevalence of loneliness significantly decreased between each survey. The higher categories of loneliness (a good amount, very much) decreased, from 11.4% (1995-97), 6.7% (2006-08), and 5.8% (2017-19). Across surveys, loneliness was significantly more common among women, the oldest, and those living alone. The prevalence of loneliness among the oldest adults living alone increased from 2006 to 2019. The gradual decline in loneliness observed from 1995 to 2019 coincided with notable societal changes in Norway. We estimated that the number of older adults experiencing loneliness in Norway could rise from 184,000 in 2020 to 286,000 in 2035, and potentially reach 380,000 in 2050.

Factors associated with non-completion of and scores on physical capability tests in health surveys: The North Health in Intellectual Disability Study.

BACKGROUND: This study investigated the completion rates, scores and factors associated with non-completion and low scores on physical capability tests in a health survey administered to adults with intellectual disabilities. METHOD: Assessment comprised body mass index (BMI), the Short Physical Performance Battery (SPPB), the timed up-and-go (TUG) test, the one-legged stance (OLS) test; and gross motor, communication and behavioural functioning tests. RESULTS: The completion rates among 93 participants (aged 17-78) were 46% for the SPPB, 42% for the TUG, and 31% for the OLS. More severe intellectual disability (OR = 3.12, p < .001) and lower BMI (OR = 0.859, p = .001) were related to test non-completion. The SPPB scores were below the reference values from the general population. Lower scores were associated with older age, motor disabilities and intellectual disability severity. CONCLUSIONS: Including physical capability tests in health surveys among adults with intellectual disabilities is important to monitor functional status and guide prevention strategies.

Preferred life expectancy and the association with hypothetical adverse life scenarios among Norwegians aged 60.

BACKGROUND: how long older individuals prefer to live given hypothetical adverse changes in health and living conditions has been insufficiently studied. OBJECTIVES: the objective of this study is to investigate the relationship between six adverse health and living conditions and preferred life expectancy (PLE) after the age of 60 years. DESIGN: cross-sectional face-to-face interviews. SETTING: population-based sample. PARTICIPANTS: 825 community dwellers aged 60 years and older in Norway. METHODS: logistic regression models were used to analyse PLE, measured with a single question: 'If you could choose freely, until what age would you wish to live?' The impact on PLE of several hypothetical scenarios, such as being diagnosed with dementia, spousal death, becoming a burden, poverty, loneliness and chronic pain was analysed by age, sex, education, marital status, cognitive function, self-reported loneliness and chronic pain. RESULTS: average PLE was 91.4 years (95% CI 90.9, 92.0), and there was no difference between men and women, but those at older ages had higher PLE than those at younger ages. The scenarios that had the strongest negative effects on PLE were dementia, followed by chronic pain, being a burden to society, loneliness, poverty and losing one's spouse. PLE among singles was not affected by the prospect of feeling lonely. The higher educated had lower PLE for dementia and chronic pain. CONCLUSION: among Norwegians 60+, the desire to live into advanced ages is significantly reduced by hypothetical adverse life scenarios, with the strongest effect caused by dementia and chronic pain.

Cohort profile: Norwegian survey of health and ageing (NORSE).

PURPOSE: The Norwegian Survey of Health and Ageing (NORSE) was set up to provide internationally comparable data on ageing in Norway, which includes measured intrinsic capacity and cognitive function. PARTICIPANTS: NORSE is a population-based health examination study of seniors aged 60+ from the 1921-1958 birth cohorts in the former Norwegian county of Oppland, interviewed and examined during 2017-19 (N = 957, 16% response rate). NORSE is to some extent based on the SHARE-questionnaire ( share-project.org ), which includes work-related information, self-assessed and retrospective health, and expectations on longevity, quality of life, volunteering activities, consumption, and financial arrangements. In addition, several objective measures of intrinsic and cognitive capacity are included in NORSE. FINDINGS TO DATE: A shorter preferred life expectancy (PLE) was found to be associated with the prospects of a life with dementia and chronic pain. Motivation for retirement was found to be related to work-life experience and health. Social media was mostly used in the younger age groups and there was a tendency towards more use in the higher educational groups. NORSE incorporates questions on religion, and older women tend to have a higher degree of religiosity (proxied as self-assessed religiosity) than men in their 80s, but more similar (and lower levels) among those in their 60s. FUTURE PLANS: NORSE participants have allowed their data to be linked to National registry data and midlife health examination studies and thereby provide a longitudinal design as well as information on disability status, socioeconomic status, household and marital status, support to/from children and parents, and pension status.

Participation in employment and day care for adults with intellectual disabilities: Equal access for all?

BACKGROUND: The employment rate for people with intellectual disabilities is low. This study aims to increase the knowledge about the association between age, gender, diagnosis, functional level, educational level, and daily activities for adults with intellectual disabilities. METHOD: A multinomial logistic analysis was applied to registry data on 12,735 adults with intellectual disabilities from the Norwegian Information System for the Nursing and Care Sector (IPLOS) and Statistics Norway (SSB). RESULTS: Higher likelihood of employment and day care participation were associated with younger age but differed between genders and diagnoses. High functional level and lack of a registered functional level decreased the likelihood for employment. Educational level was not associated with employment. CONCLUSIONS: The systematic differences in employment and day care participation among people with intellectual disabilities indicate that actions are needed to prevent inequalities. Improved individual assessment of personal resources and wishes might promote participation in employment and day care.

Subjective memory impairment, instrumental activities of daily living and longitudinal effect on mortality among older adults in a population-based cohort study: The HUNT Study.

Background: Subjective impairment in memory and instrumental activities in daily living (IADL) are associated with future cognitive decline and poorer mental health in older adults, but their association with mortality is uncertain. Our aim was to examine the associations between subjective memory and IADL impairments and all-cause mortality, as well as the mortality risk for reporting both memory and IADL impairments. Methods: Data from the 70-year-old and older cohort in the third survey of a population-based study, the Nord-Trøndelag Health Study (HUNT3), were linked to the Norwegian Causes of Death Registry. A total of 5802 older adults had complete data from HUNT3 (70.8% of the 70+ cohort). The mean follow-up time was 8.0 years, and 1870 respondents had died. Associations between subjective memory and ADL impairments with mortality were analysed in Cox regression models adjusted for covariates with attained age as the timescale. Analyses were performed separately for two age groups - 70-79 and 80+ years - to fulfil the proportional hazards assumption. Results: Subjective impairments in short-term memory and IADL were significantly associated with mortality both separately and combined. These associations were strongest in the 70- to 79-year-old group, where reporting impairment on one short-term memory item increased the mortality risk by 51% (hazard ratio=1.51; 95% confidence interval 1.20-1.91). Long-term memory impairments were not associated with mortality in the adjusted models. Conclusions: Subjective short-term memory impairments and IADL impairments are associated with increased mortality risk. Neither of these symptoms should be regarded as benign aspects of ageing, and concerns should be properly addressed.

Health checks for adults with intellectual disabilities. / Helsekontroll for voksne med utviklingshemming.

New national guidelines recommend annual health checks for adults with intellectual disabilities. Adults with a diagnosis of intellectual disability die earlier, have poorer health and more difficulty accessing health services than the general population. Annual health checks have been recommended in Norway and internationally for many years because they help identify ill health and serious illnesses.

Association of psychological distress late in life and dementia-related mortality.

OBJECTIVE: It is not fully understood how subjective feelings of psychological distress prognosticate dementia. Our aim was to investigate the association between self-reported psychological distress and risk of dementia-related mortality. METHOD: We included 31,043 eligible individuals between the ages of 60 and 80 years, at time of examination, from the CONOR (Cohort of Norway) database. They were followed for a period of 17.4 years (mean 11.5 years). The CONOR Mental Health Index, a seven-item self-report scale was used. A cut-off score equal to or above 2.15 on the scale denoted psychological distress. Cox regression was used to assess the association between psychological distress and risk of dementia-related mortality. RESULTS: Total number of registered deaths was 11,762 and 1118 (9.5%) were classified as cases of dementia-related mortality. We found that 2501 individuals (8.1%) had psychological distress, of these, 119 (10.6%) had concomitant dementia-related mortality. Individuals with psychological distress had an increased risk of dementia-related mortality HR = 1.52 (95% confidence interval (CI) 1.25-1.85) after adjusting for age, gender and education. The association remained significant although attenuated when implemented in a full adjusted model, including general health status, smoking, obesity, hypertension, diabetes and history of cardiovascular disease; hazard ratio, HR = 1.30 (95% CI 1.06-1.59). CONCLUSION: Our results indicate that psychological distress in elderly individuals is associated with increased risk of dementia-related mortality. Individuals at increased risk of dementia may benefit from treatments or interventions that lessen psychological distress, but this needs to be confirmed in future clinical studies.

Alcohol consumption and risk of dementia up to 27 years later in a large, population-based sample: the HUNT study, Norway.

The relationship between alcohol consumption and dementia risk is unclear. This investigation estimates the association between alcohol consumption reported in a population-based study in the mid-1980s and the risk for dementia up to 27 years later. The entire adult population in one Norwegian county was invited to the Nord-Trøndelag Health Study during 1984-1986 (HUNT1): 88 % participated. The sample used in this study includes HUNT1 participants born between 1905 and 1946 who completed the questionnaire assessing alcohol consumption. A total of 40,435 individuals, of whom 1084 have developed dementia, are included in the analysis adjusted for age, sex, years of education, hypertension, obesity, smoking, and symptoms of depression. When adjusting for age and sex, and compared to reporting consumption of alcohol 1-4 times during the last 14 days (drinking infrequently), both abstaining from alcohol and reporting consumption of alcohol five or more times (drinking frequently) were statistically significantly associated with increased dementia risk with hazard ratios of 1.30 (95 % CI 1.05-1.61) and 1.45 (1.11-1.90), respectively. In the fully adjusted analysis, drinking alcohol frequently was still significantly associated with increased dementia risk with a hazard ratio of 1.40 (1.07-1.84). However, the association between dementia and abstaining from alcohol was no longer significant (1.15, 0.92-1.43). Equivalent results for Alzheimer's disease and vascular dementia indicated the same patterns of associations. When adjusting for other factors associated with dementia, frequent alcohol drinking, but not abstaining from alcohol, is associated with increased dementia risk compared to drinking alcohol infrequently.

Short- and long-term mortality risk associated with the use of antipsychotics among 26,940 dementia outpatients: a population-based study.

OBJECTIVE: To investigate short- and long-term mortality risk associated with the use of antipsychotics in dementia outpatients, assessing the risk over specific time frames and quantifying the risk by the individual antipsychotics. METHODS: This population-based study used data from the Norwegian Prescription Database. The study sample included 26,940 dementia outpatients aged 65 years or older prescribed antidementia drugs and psychotropics from Norwegian pharmacies between 2004 and 2010. RESULTS: Cox survival analyses, adjusted for age, gender, mean daily defined dose, and severe medical conditions, showed that antipsychotic use compared with other psychotropics involved approximately twice the mortality risk in outpatients with dementia. Furthermore, these results are consistent for all investigated time points after first dispensing the drugs (hazard ratio [HR]30 days = 2.1 [95% confidence interval {CI}: 1.6-2.9] to HR 730-2,400 days = 1.7 [95% CI: 1.6-1.9]). Haloperidol was associated with higher mortality risk (HR 30 days = 1.7 [95% CI: 1.0-3.0] to HR 730-2,400 days = 1.4 [95% CI: 1.0-1.9]) than risperidone. CONCLUSION: This first study to observe antipsychotic use and mortality in dementia outpatients over more than 6 years clearly shows that antipsychotics involve increased short- and long-term mortality risk. Physicians may justly consider antipsychotics to be the best option for some dementia patients among available nonpharmacologic and pharmacologic treatments. However, although causal conclusions are precluded due to limited adjustments in the analyses, the findings support the current treatment recommendations that antipsychotics should be avoided or used with great caution.

Mental health and wellbeing in spouses of persons with dementia: the Nord-Trøndelag Health Study.

BACKGROUND: Caring for a spouse diagnosed with dementia can be a stressful situation and can put the caregiving partner at risk of loss of mental health and wellbeing. The main aim of this study was to investigate the relationship between dementia and spousal mental health in a population-based sample of married couples older than 55 years of age. The association was investigated for individuals living together with their demented partner, as well as for individuals whose demented partner was living in an institution. METHODS: Data on dementia were collected from hospitals and nursing homes in the county of Nord-Trøndelag, Norway. These data were combined with data on spousal mental health, which were collected in a population-based health screening: the Nord-Trøndelag Health Study (HUNT). Of 6,951 participating couples (>55 years), 131 included one partner that had been diagnosed with dementia. RESULTS: Our results indicate that after adjustment for covariates, having a partner with dementia is associated with lower levels of life satisfaction and more symptoms of anxiety and depression than reported by spouses of elderly individuals without dementia. Spouses living together with a partner diagnosed with dementia experienced moderately lower levels of life satisfaction (0.35 standard deviation [SD]) and more symptoms of depression (0.38 SD) and anxiety (0.23 SD) than did their non-caregiving counterparts. Having a partner with dementia that resided in a nursing home was associated with clearly lower life satisfaction. Compared with non-caregivers, these spouses reported lower levels of life satisfaction (1.16 SD), and also more symptoms of depression (0.38 SD), and more symptoms of anxiety (0.42 SD). CONCLUSIONS: Having a partner with dementia is associated with loss of mental health and reduced life satisfaction. The risk of adverse mental health outcomes is greatest after the partner's nursing home admission.

Subjective age and the association with intrinsic capacity, functional ability, and health among older adults in Norway.

This study investigates the relationships between subjective age, intrinsic capacity, functional ability and health among Norwegians aged 60 years and older. The Norwegian Survey of Health and Ageing (NORSE) is a population-based, cross-sectional study of home-dwelling individuals aged 60-96 years in the former county of Oppland. Age- and sex-adjusted regression models were used to investigate the gap between subjective and chronological age and this gap's association with self-reported and objectively measured intrinsic capacity (covering all six sub domains defined by WHO), health, and functional ability among 817 NORSE participants. The results show most participants felt younger than their chronological age (86.5%), while relatively few felt the same as their chronological age (8.3%) or older (5.2%). The mean subjective age was 13.8 years lower than mean chronological age. Participants with urinal incontinence, poor vision, or poor hearing felt 3.1 [95% confidence interval (CI) (0.6, 5.5)], 2.9 [95% CI (0.2, 5.6)], and 2.9 [95% CI (0.3, 5.5)] years older, respectively, than participants without those conditions, whereas none of the following factors-anxiety, depression, chronic disease, Short Physical Performance Battery score, grip strength, cognition, or frailty-significantly had an impact on the gap. In line with prior research, this study finds that feeling considerably younger than one's chronological age is common at older ages. However, those with poor hearing, poor vision, and urinal incontinence felt less young compared to those not having these conditions. These relationships may exert undesirable effects on vitality and autonomy, which are considered key factors of intrinsic capacity and healthy ageing.

Increased mortality risk for adults aged 25-44 years with long-term disability: A prospective cohort study with a 35-year follow-up of 30,080 individuals from 1984-2019 in the population-based HUNT study.

Background: Differences in survival between groups may reflect avoidable and modifiable inequalities. This study examines the 35-year mortality risk for adults aged 25-44 years in the mid-1980s with disability due to vision, hearing, or motor impairment; physical illness; or mental health problems. Methods: This Norwegian study was based on data from the Trøndelag Health Study (HUNT1, 1984-86, and HUNT2, 1995-97) linked to tax-registry data for deaths before 15 November 2019. Mortality risk was estimated by Cox regression analysis adjusted for age and sex. Sensitivity analysis included the following possible mediators: education, work, living situation, body mass index, systolic blood pressure and smoking. Findings: Of the 30,080 HUNT1 participants aged 25-44 years, 5071 (16.9%) reported having disability. During the 35 years of follow-up, 1069 (21.1%) participants with disability and 3107 (12.4%) without disability died. Individuals with any type of disability had 62% higher mortality risk compared to those without a disability, adjusted by age and sex. The highest mortality risks were observed for disability due to severe motor impairment (HR=3.67, 95%CI=2.89-4.67) and severe mental health problems (HR=3.40, 95%CI=2.75-4.23) compared to those without these disabilities. Increased mortality risk was found for all the included disability types. The associations were somewhat mediated, especially by education, work and living situation. Interpretation: This study shows that among adults aged 25-44 years, the risk of death increases with disability of different types and severity levels, particularly for disability related to mental health problems or motor impairment. Funding: None.

Concomitant use of anti-dementia drugs with psychotropic drugs in Norway--a population-based study.

PURPOSE: Concomitant use of anti-dementia drugs with psychotropic drugs is potentially problematic in patients with dementia. The aim of this study was to investigate how frequently patients in Norway use anti-dementia drugs concomitantly with psychotropic drugs. METHODS: Analyses are based on data from the Norwegian Prescription Database. All patients who had an anti-dementia drug (ATC-code N06D) dispensed from a Norwegian pharmacy between January 2004 and July 2009 were included. RESULTS: A total of 33,816 individuals received anti-dementia drugs at some time during this period. The total concomitant use of anti-dementia drugs with psychotropic drugs was 57.4% in men and 65.8% in women. Compared with men, a significantly higher percentage of women used antidepressants (35.8% versus 27.2%), mild hypnotics (28.8% versus 23.6%), benzodiazepines (25.4% versus 20.8%) and opioids (22.8% versus 17.4%) concomitantly with anti-dementia drugs. Concomitant use of antipsychotics with anti-dementia drugs was about 16% for both male and female patients. Of the total sample, 11.9% of the women and 11.7% of the men used acetylcholinesterase inhibitor (AChEI) anti-dementia drugs concomitantly with an interacting psychotropic drug. CONCLUSION: The concomitant use of psychotropic drugs with anti-dementia drugs was extensive, especially among women. Co-medication with potentially interacting drugs occurred at a rate of one in 10. The concomitant use of anti-dementia drugs with psychotropic drugs identified in this study may inform the ongoing clinical debate about drug use in this patient group.

Exploring within- and between-gender differences in burnout: 8 different occupational groups.

OBJECTIVES: The aim of this study was to examine gender differences in burnout within and between occupations using latent mean analysis. METHODS: Burnout was measured using the Oldenburg Burnout Inventory (OLBI), designed to assess the two sub-dimension exhaustion and disengagement. Men and women from eight different occupational groups in Norway were investigated: lawyers, physicians, nurses, teachers, church ministers, bus drivers and people working in advertising and information technology (n = 4,965). The average age was 42 years (SD 10.8), and 50.5% of the respondents were female. Within- and between-gender differences were examined by multi-group latent mean analysis by means of LISREL. RESULTS: Significant latent mean differences in the two dimensions of burnout between men and women were demonstrated. In general, the analyses indicate that overall, women report more exhaustion, but not more disengagement, than men. However, separate analyses indicate that the gender differences vary across occupational groups, especially for the disengagement dimension. Within-gender analyses suggest an approximately similar burnout profile across occupational groups for men and women. CONCLUSIONS: Despite gender equality in society in general, and inconclusive findings in previous studies on gender differences in burnout, women in this study seem to experience slightly higher burnout levels than men. Occupational differences found in the burnout profiles indicate that some professions may be more prone to burnout than others. For the occupational groups most at risk, more research is needed to disclose potential organizational factors that may make these workers more prone to burnout than others.

Personal vulnerability and work-home interaction: the effect of job performance-based self-esteem on work/home conflict and facilitation.

The aim of the present study was to examine the longitudinal relationship between job performance-based self-esteem (JPB-SE) and work-home interaction (WHI) in terms of the direction of the interaction (work-to-home vs. home-to-work) and the effect (conflict vs. facilitation). A sample of 3,475 respondents from eight different occupational groups (lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working in advertising and information technology) supplied data at two points of time with a two-year time interval. The two-wave, cross-lagged structural equations modeling (SEM) analysis demonstrated reciprocal relationships between these variables, i.e., job performance-based self-esteem may act as a precursor as well as an outcome of work-home interaction. The strongest association was between job performance-based self-esteem and work-to-home conflict. Previous research on work-home interaction has mainly focused on situational factors. This longitudinal study expands the work-home literature by demonstrating how individual vulnerability (job performance-based self-esteem) contributes to the explanation of work-home interactions.
