Multimorbidity increases the risk for sarcopenia onset: Longitudinal analyses from the English Longitudinal Study of Ageing.
2021
Background-\ud \ud Cross-sectional studies have demonstrated that multimorbidity is associated with sarcopenia. However, to date, this association has not been extensively investigated longitudinally. Therefore, the aim of the present paper was to explore the association between multimorbidity at baseline and sarcopenia onset over 12 years of follow-up in a large representative sample of the English older adult population.\ud \ud Methods-\ud \ud Representative data from the English Longitudinal Study of Ageing (ELSA) were analyzed. Multimorbidity at baseline was defined as ≥2 medical conditions, of 17 conditions included. Participants were considered to have sarcopenia if they had low handg…
Sexual activity and cognitive decline in older age: a prospective cohort study
2020
Background: To explore the association between sexual activity and change in cognitive function over 4 years in a representative sample of older adults in England. Methods: Data were from 1963 men and 2513 women participating in Wave 6 (2012/2013) and Wave 8 (2016/2017) of the English Longitudinal Study of Ageing. Participants reported whether or not they had engaged in any sexual activity in the last year. Cognitive function was assessed with tests of immediate and delayed recall. Adjusted general linear models were used to test associations between sexual activity and changes in cognitive function. Results: Men who were sexually active at baseline had better preservation in immediate (0.1…
Is frailty associated with life-space mobility and perceived autonomy in participation outdoors? A longitudinal study
2016
Background: essential aspects of independence in community mobility among older people concern the control over where, when and how to participate (perceived autonomy), and actual mobility (life-space mobility; frequency, distance and need of assistance). We studied relationships between frailty and life-space mobility and perceived autonomy in participation outdoors among community-dwelling 75–90 years old people. Methods: longitudinal analyses of the ‘Life-space mobility in old age’ cohort study (n = 753). Life-space mobility (Life-Space Assessment, range 0–120) and perceived autonomy in participation outdoors (Impact on Participation and Autonomy subscale ‘autonomy outdoors’, range 0–20)…
Telomere length and physical performance at older ages:an individual participant meta-analysis
2013
<p>Background: Telomeres are involved in cellular ageing and shorten with increasing age. If telomere length is a valuable biomarker of ageing, then telomere shortening should be associated with worse physical performance, an ageing trait, but evidence for such an association is lacking. The purpose of this study was to examine whether change in telomere length is associated with physical performance.</p>\ud \ud <p>Methods: Using data from four UK adult cohorts (ages 53–80 years at baseline), we undertook cross-sectional and longitudinal analyses. We analysed each study separately and then used meta-analytic methods to pool the results. Physical performance was measured us…
Validity of a single question to assess habitual physical activity of community-dwelling older people
2017
The aim is to determine concurrent validity of a single self-report habitual physical activity (PA) question against accelerometer-based PA and mobility variables, and corresponding changes in self-reported PA and mobility. Cross-sectional and longitudinal data of the "Life-space mobility in old age" (LISPE) cohort and its substudy on PA were utilized. At baseline, 848 community-dwelling, 75- to 90-year-old people living independently in central Finland participated in home-based interviews. One and 2 years later, 816 and 761 of them were reassessed by phone, respectively. Tri-axial accelerometer data over 7 days were collected following the baseline assessments in a subsample of 174. Self-…
Genetic endowments, parental resources and adult health: Evidence from the Young Finns Study
2017
This paper uses longitudinal survey data linked to administrative registers to examine socioeconomic gradients in health, particularly whether the effects of genetic endowments interact with the socioeconomic resources of the parental household. We find that genetic risk scores contribute to adult health measured by biomarkers. This result is consistent with the findings from genome-wide association studies. Socioeconomic gradients in health differ based on biomarker and resource measures. Family education is negatively related to obesity and the waist-hip ratio, and family income is negatively related to low-density lipoprotein cholesterol and triglyceride levels. Parental resources do not…
Obesity History as a Predictor of Walking Limitation at Old Age*
2007
Objective: To study whether walking limitation at old age is determined by obesity history. Research Methods and Procedures: In a retrospective longitudinal study based on a representative sample of the Finnish population of 55 years and older (2055 women and 1337 men), maximal walking speed, body mass, and body height were measured in a health examination. Walking limitation was defined as walking speed <1.2 m/s or difficulty in walking 0.5 km. Recalled height at 20 years of age and recalled weight at 20, 30, 40, and 50 years of age were recorded. Results: Subjects who had been obese at the age of 30, 40, or 50 years had almost a 4-fold higher risk of walking limitation compared to non-obe…
Physical Activity and Accomplishment of Recommendations in University Students with Disabilities: A Longitudinal Study
2021
University settings are socio-environmental contexts that can reduce health disparities in students with disabilities. Therefore, the aim of this study was twofold: (a) to examine the longitudinal physical activity (PA) changes of Spanish university students with disabilities during a three-year period
Polypharmacy Is Associated With Higher Frailty Risk in Older People: An 8-Year Longitudinal Cohort Study
2017
Objective To investigate whether polypharmacy is associated with a higher incidence of frailty in a large cohort of North Americans during 8 years of follow-up. Design Longitudinal study, follow-up of 8 years. Participants A total of 4402 individuals at high risk or having knee osteoarthritis free from frailty at baseline. Measurements Details regarding medication prescription were captured and categorized as 0–3, 4–6, and ≥7. Frailty was defined using the Study of Osteoporotic Fracture index as the presence of ≥2 out of (1) weight loss ≥5% between baseline and the subsequent follow-up visit; (2) inability to do 5 chair stands; and (3) low energy level according to the Study of Osteoporotic…
Frailty Is Associated with an Increased Risk of Incident Type 2 Diabetes in the Elderly
2016
Objective To investigate whether frailty is associated with an increased risk of incident type 2 diabetes mellitus (T2DM) in a prospective cohort of community-dwelling older people. Design Longitudinal study, mean follow-up of 4.4 years. Setting Progetto Veneto Anziani (Pro.V.A.) study that involved older community-dwellers. Participants 1754 men and women older than 65 years without T2DM at baseline. Measurements Frailty status was defined according to Fried criteria and categorized as frailty (≥3 criteria), prefrailty (1-2 criteria), or no frailty (0 criterion). Incident T2DM was defined as fasting plasma glucose (FPG) ≥7.0 mmol/L, or glycosylated hemoglobin ≥6.5%, the use of glucose-lowe…
