Marital transitions and life satisfaction
2014
This article is based on three waves of data collected by the Nord-Trøndelag Health Study (HUNT), Norway. It investigates changes in life satisfaction associated with transition both into and out of marital unions (marriages and cohabitations). It provides longitudinal data on life satisfaction for a larger sample ( N=57,446), a longer age span (19–101 years) and over a longer observation period (22 years) than previously published research on this topic. The large sample permits interaction analyses focusing on small gender/age categories. Results indicate that marriage and cohabitation does enhance life satisfaction, but more for some groups than for others. Cohabitation enhances life sat…
Heritability of Lung Function: A Twin Study Among Never-Smoking Elderly Women
2011
Most studies on lung function heritability have been conducted in smokers and non-smokers using cross-sectional study design. Smoking patterns may, however, confound the contribution of genetic factors. We investigated heritability of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio longitudinally, excluding the effects of smoking. A sample of never smoking female twins (n = 374), aged 63–76 at baseline, answered health questionnaires and attended spirometry in years 2000 and 2003. Bivariate structural equation modeling, restricted to adequate spirometry performances (baseline n = 339, follow-up n = 252), was used to estimate genetic and environ…

Work ability in midlife as a predictor of mortality and disability in later life: a 28-year prospective follow-up study.
2011
Background: Poor work ability correlates with increased morbidity and early retirement from the workforce, but the association in old age is not known. We investigated work ability in midlife among white-collar and blue-collar employees as a predictor of mortality and disability 28 years later. Methods: A total of 5971 occupationally active people aged 44–58 years participated in the Finnish Longitudinal Study of Municipal Employees (FLAME) in 1981. Perceived work ability relative to lifetime best was categorized as excellent, moderate or poor. In 2009, the ability to perform activities of daily living was assessed among 2879 respondents (71.0% of the survivors). Mortality data were availab…
Self-rated resilience and mobility limitations as predictors of change in active aging during COVID-19 restrictions in Finland : a longitudinal study
2021
AbstractSocial distancing during the COVID-19 pandemic decreased older people’s opportunities to lead an active life. The purpose of this study was to investigate whether walking difficulties predict changes in leading an active life during the COVID-19 social distancing recommendation compared to 2 years before, and whether self-rated resilience moderates this association among older people. Data were collected during social distancing recommendation in May and June 2020 and 2 years before (2017–18) among community-living AGNES study participants initially aged 75, 80, or 85 years (n = 809). Leading an active life was assessed with the University of Jyväskylä Active Aging Scale (UJACAS; to…
Disability, physical activity, and muscle strength in older women: The women's health and aging study
1999
Abstract Objective: To study associations of motor disability, physical activity, and muscle strength in older women, in particular to investigate whether model of spiraling decrease is expressed in the data. Design: Cross-sectional analysis using data from the base-line measurements of The Women's Health and Aging Study (WHAS). Setting: Participants' homes. Participants: A total of 1,002 disabled women aged 65 years and older living in the community. Outcome Measures: Motor disability was measured by the number of self-reported difficulties in grasping, lifting 101b, walking across a small room, walking 14 mile, climbing 10 steps, and doing heavy housework. Level of physical activity was d…
Effect of long-term leisure time physical activity on lean mass and fat mass in girls during adolescence.
2011
The purpose of this 7-yr prospective longitudinal study was to examine if the level and consistency of leisure-time physical activity (LTPA) during adolescence affected the quantity and distribution of lean mass (LM) and fat mass (FM) at early adulthood. The study subjects were 202 Finnish girls who were 10–13 yr old at baseline. LM and FM of the total body (TB), arms, legs, and trunk were assessed by dual-energy X-ray absorptiometry. Muscle cross-sectional area (mCSA) of the left leg was assessed by peripheral quantitative computed tomography. Scores of LTPA were obtained by questionnaire. Girls were divided into four groups comprising those with consistently low (GLL) or consistently hig…
Sedentary behaviours and cognitive function among community dwelling adults aged 50+ years: Results from the Irish longitudinal study of ageing
2020
Background:\ud \ud Sedentary behaviours (SB) are risk factors for poor cardiovascular health and all-cause mortality. However, their role in cognitive health in older adults is unclear. A few studies have examined associations between sedentary behaviours and cognition, but are limited by heterogeneity and insufficient longitudinal analyses. Therefore more robust studies, which would address identified limitations, are needed to accurately determine associations.\ud \ud Method:\ud \ud This study analysed data collected from participants aged 50+ years of The Irish Longitudinal Study of Ageing (TILDA). We conducted cross-sectional linear regression with multivariate imputation analyses of ba…
The Multidimensional Prognostic Index Predicts Falls in Older People: An 8-Year Longitudinal Cohort Study of the Osteoarthritis Initiative
2020
Objectives: Falls are associated with several negative outcomes. Early identification of those who are at risk of falling is of importance in geriatrics, and comprehensive geriatric assessment (CGA) seems to be promising in this regard. Therefore, the present study investigated whether the multidimensional prognostic index (MPI), based on a standard CGA, is associated with falls in the Osteoarthritis Initiative (OAI). Design: Longitudinal, 8 years of follow-up. Setting and participants: Community-dwelling older people (≥65 years of age) with knee osteoarthritis or at high risk for this condition. Methods: A standardized CGA including information on functional, nutritional, mood, comorbiditi…
Risk of progression to diabetes and mortality in older people with prediabetes: The English longitudinal study on ageing
2022
Abstract Aims Prediabetes is used to identify people at increased risk for diabetes. However, the importance of prediabetes in older populations is still poorly explored. Therefore, we aimed to investigate the prevalence of prediabetes, based on either glycated haemoglobin (HbA1c) levels or fasting glucose (FG) levels, or both and the progression of prediabetes to diabetes or to mortality in older participants of the English Longitudinal Study on Ageing. Materials and methods Prediabetes was categorized based on HbA1c levels (5.7%–6.4%) and/or FG levels (5.6–7.0 mmol/L). Information regarding mortality and incident diabetes were recorded during follow-up period of 10 years. Results In 2027 …
