  • Changes in survival probabilities and mortality risks among population living with Down syndrome born 1967–2018

    Open AccessTeferi Mekonnen, Dana Kristjansson et al.ARTICLEBMC Public Health2025

    While medical advancements and increased awareness have improved the life expectancy of individuals with Down syndrome (DS), studies on cohort-specific differences in mortality risk and long-term survival outcomes among individuals with DS remain limited. We assessed cohort differences in survival probabilities and mortality risk among individuals with DS born 1967–2018, using Norwegian national registry data. Utilizing the Medical Birth Registry…

  • Smoking is associated with increased risk for dementia

    Open AccessChristian Myrstad, Marie Larssen et al.ARTICLEBMC Public Health2025

    Current smoking was associated with an increased risk of dementia. Among those 85+ at follow-up, being a smoker 20+ years earlier was not associated with an increased risk of dementia, probably because death was a competing risk. In former smokers, there were no significant associations with dementia. Our results add to the literature an optimism about the effects of changing smoking habits and may encourage smoking cessation

  • Mediators of educational differences in dementia risk later in life

    Open AccessTeferi Mekonnen, Vegard Skirbekk et al.ARTICLEBMC Public Health2025

    Despite a well-known inverse association between education and dementia risk, the mediating mechanisms are not well understood. We explored how lifestyle and health risk factors across the life-course mediate the relationship between education and dementia among adults aged 70 + years. We included 7,655 participants with dementia diagnoses and education information, using a historical cohort design linking prospective exposure data across the lif…

  • Addressing relationship quality of people with dementia and their family carers

    Open AccessMaria J Marques, Bob Woods et al.ARTICLEFrontiers in Psychiatry2024

    Specific profiles of persons with dementia and their carers are at risk of worse relationship quality trajectories. By considering modifiable related factors (e.g., carers' stress), our findings can help develop tailored, effective interventions

  • Public knowledge about dementia risk reduction in Norway

    Open AccessGrete Kjelvik, Mwaura Anne et al.ARTICLEBMC Public Health2022

    The results indicate that 70% of the Norwegian public are aware of the potential for dementia risk reduction in general. However, there are major gaps in existing knowledge, particularly for cardiovascular risk factors such as hypertension, coronary heart disease, hypercholesterolemia and metabolic factors (diabetes, obesity). These findings underline the importance of further informing the Norwegian public about lifestyle-related risk and protec…

  • Marital Histories and Associations With Later-Life Dementia and Mild Cognitive Impairment Risk in the Hunt4 70+ Study in Norway

    Open AccessVegard Skirbekk, CATHERINE E BOWEN et al.ARTICLEJournal of Aging and Health2022Cited by: 1References: 8

    Objectives: Earlier studies suggest that being married in later life protects against dementia, and that being single in old age increases the risk of dementia. In this study, we examine midlife marital status trajectories and their association with dementia and mild cognitive impairment (MCI) at ages 70 plus using a large population based sample from Norway. Methods: Based on a general population sample linked to population registries ( N = 8706…

  • The Truth behind the Zeros

    Kristoffer H Hellton, Jason L Cummings et al.ARTICLEMultivariate Behavioral Research2021

    Psychiatric syndromes in dementia are often derived from the Neuropsychiatric Inventory (NPI) using principal component analysis (PCA). The validity of this statistical approach can be questioned, since the excessive proportion of zeros and skewness of NPI items may distort the estimated relations between the items. We propose a novel version of PCA, ZIBP-PCA, where a zero-inflated bivariate Poisson (ZIBP) distribution models the pairwise covaria…

  • Cohort profile

    Open AccessBjorn H Strand, Vegard Skirbekk et al.ARTICLEBMC Public Health2021

    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

  • Self‐reported quality of life in people with dementia attending a day‐care programme in Norway

    Open AccessMargit Gausdal Strandenæs, Anne Lund et al.ARTICLEHealth & Social Care in the…2021References: 4

    The objectives of the study were (a) to compare self-reported Quality of Life (QoL) in a 24-month follow-up of people with dementia attending day care designed for people with dementia (day-care group, DC) with people with dementia who did not attend day care (control group, CG) and (b) to explore factors associated with QoL. A quasi-experimental design with a 24-month follow-up period was used. The DC group included 181 participants recruited fr…

  • Carers’ experiences of timely access to and use of dementia care services in eight European countries

    Open AccessHannah Jelley, Liselot Kerpershoek et al.ARTICLEAgeing and Society2021References: 33

    Timely access to care services is crucial to support people with dementia and their family carers to live well. Carers of people with dementia (N = 390), recruited from eight countries, completed semi-structured interviews about their experiences of either accessing or not using formal care services over a 12-month period in the Access to Timely Formal Care (Actifcare) study. Participant responses were summarised using content analysis, categoris…

  • Obtaining EQ-5D-5L utilities from the disease specific quality of life Alzheimer’s disease scale

    Open AccessInes Rombach, Marvi Iftikhar et al.ARTICLEQuality of Life Research2020

    The recommended mapping algorithm allows researchers for the first time to estimate EQ-5D values from QoL-AD data, enabling cost-utility analyses using datasets where the QoL-AD but no utility measures were collected

  • A validation study of the CarerQol instrument in informal caregivers of people with dementia from eight European countries

    This study demonstrates the convergent and clinical validity of the CarerQol instrument to evaluate the impact of providing informal care for people with dementia

  • A validation study of the Icecap-O in informal carers of people with dementia from eight European Countries

    Open AccessMeg Perry‐Duxbury, Job Van Exel et al.ARTICLEQuality of Life Research2019

    The ICECAP-O appears to be a valid measure of well-being in informal carers for people with dementia. The ICECAP-O may therefore be useful as an outcome measure in economic evaluations of interventions aimed at such informal carers, when these aim to improve well-being beyond health

  • Optimizing access to and use of formal dementia care

    This paper reports on qualitative data from the Actifcare study investigating experiences, attitudes, barriers and facilitators concerning access to and use of formal care. A total of 85 semi-structured in-depth interviews were conducted in eight European countries. Results were analysed with a deductive content analysis, first within country and then integrated in a cross-national analysis. Overall, analysis of the in-depth interviews revealed t…

  • Depression and Quality of Life in Older Persons

    Open AccessHeidi Sivertsen, Guro Hanevold Bjørkløf et al.ARTICLEDementia and Geriatric Cognitive…2015

    Background: Depression is a prevalent and disabling condition in older persons (≥60 years) that increases the risk of mortality and negatively influences quality of life (QOL). The relationship between depression, or depressive symptoms, and QOL has been increasingly addressed by research in recent years, but a review that can contribute to a better understanding of this relationship in older persons is lacking. Against this background, we undert…
