Approximately 16% of the global population were estimated to have a disability in 2023, and this number is expected to increase mainly due to longer life expectancy and a rise in non-communicable diseases.1 Some studies also suggest that the number of years lived with a disability is increasing in younger cohorts.2,3 The interactions between individuals and society affect whether a person's health experience is considered a disability.4 According to WHO, activity limitations, such as sensory and mobility difficulties, are one of three domains of disability, with the other two being bodily or mental impairment and participation restrictions.5 In a prospective cohort study published in The Lancet, Raed A Joundi and colleagues6 included 175 584 individuals (aged 35–70 years) from 25 high-income, middle-income, and low-income countries, providing important insight into global differences in the prevalence of activity limitations and the use of assistive devices. The prevalence of dementia is expected to increase by 50% in high-income countries and by 80% in low-income and middle-income countries by 2030.10 Additionally, as many as 14% of older adults live with a mental disorder, accounting for 8·8% of the total years lived with disability in older adults.11 According to the WHO Mental Health Atlas, there are substantial global disparities in mental health services. [...]the median number of mental health hospital beds ranges from below two per 100 000 people in low-income countries to more than 25 per 100 000 people in high-income countries.12 The study by Joundi and colleagues6 highlights marked differences in activity limitations between world regions, providing an important basis for further research on global disparities in health and disability and for public health interventions worldwide.

To investigate patterns and correlates of depression among Norwegian older adults (age 70+), 1995-2019, and estimate the number of older adults with depression by 2050. Three surveys of the Trøndelag Health Study (Norway): HUNT2 (1995-96), HUNT3 (2007-08), and HUNT4 (2017-19). 22,822 home dwellers aged 70 + who participated in at least one of the three surveys. Depression was defined as scores [greater than or equal to]8 on the depression subscale of the Hospital Anxiety and Depression Scale. Covariates included sex, age, education, marital status, and reported loneliness. Depression prevalence (%) was standardized to the Norwegian population by age, sex, and education for years close to the initial HUNT survey year (1995, 2006, and 2016). Projection of the total number of individuals with depression in the coming decades were estimated. Predictors of depression were analyzed with logistic regression and the potential reduction in depression prevalence by reducing the prevalence of loneliness was estimated. Standardized depression prevalence decreased from 16.7% (HUNT2) to 14.9% (HUNT3), and 11.5% (HUNT4), and was highest among men, the oldest (85+), the lower-educated, and in earlier surveys (all p < 0.001). Living alone was also associated with higher depression prevalence, but only if loneliness was present. While depression rates are falling, we expect the number of depressed individuals to double by 2050 as the population ages. Depression rates among adults aged 70 + decreased by 50% from 1995 to 2019, but less so among the oldest old. The rates were highest among single older men. Despite decreasing prevalence, the number of depressed older adults will increase significantly in the future. Given the major individual and societal costs of depression, this trend is alarming for societies preparing for the challenges posed by population aging. This can, however, be addressed by addressing predictors of depression.

To investigate patterns and correlates of depression among Norwegian older adults (age 70+), 1995-2019, and estimate the number of older adults with depression by 2050. Population-based cross-sectional study. Three surveys of the Trøndelag Health Study (Norway): HUNT2 (1995-96), HUNT3 (2007-08), and HUNT4 (2017-19). 22,822 home dwellers aged 70 + who participated in at least one of the three surveys. Depression was defined as scores ≥8 on the depression subscale of the Hospital Anxiety and Depression Scale. Covariates included sex, age, education, marital status, and reported loneliness.

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.

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.

People with intellectual disabilities have increased life expectancy compared to just a few decades ago, and there is a lack of knowledge about the experiences of transition into retirement for this group. In this study, semi-structured in-depth interviews with seven retirees with intellectual disabilities were conducted in order to investigate their reasons for retirement, experiences of the transition, their activities and satisfaction with their lives as retirees. Data was analysed with systematic text condensation. Most participants described that, although they experienced the retirement process and transition as abrupt, retirement had a positive impact on health, satisfaction and self-determination. Findings in this novel study in a Nordic context are need of increased knowledge on ageing and retirement among people with intellectual disabilities, and that individual guidance might improve their transition into retirement.

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 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 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.

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-Tr0ndelag 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.
