Lifetime leisure-time physical activity and the risk of depressive symptoms at the ages of 65–74years: The FIN-D2D survey
2011
To investigate the association between lifetime leisure-time physical activity (LTPA) and depressive symptoms (DS) based on the population-based FIN-D2D cross-sectional survey conducted in 2007.Nine hundred twenty seven randomly selected Finnish men and women aged 65-74 years were included in this study. DS were determined with the Beck Depression Inventory (≥10 points), and lifetime historical LTPA frequency from age 15 years onwards was recalled retrospectively.The frequency of LTPA was highest at the ages of 15-24 years in both the DS present and not present groups (14.6 times per month). LTPA frequency was significantly lower among those with DS compared with those without DS at the age…
The immediate impact of lockdown measures on mental health and couples’ relationships during the COVID-19 pandemic
2021
BackgroundLockdown measures during the COVID-19 pandemic are expected to have negative effects on mental health and relationship quality. However, little is known about the magnitude of these psychological effects on a population level and for vulnerable subgroups.MethodsA representative sample (N = 2503; 50.2% female; mean age = 49.5) of the German population was assessed face-to-face during the COVID-19 pandemic (February 10-April 25, 2020). They were examined for differences in mental health (BSI-18) and relationship quality (PFB) in a pre-lockdown and lockdown subsamples. After testing and establishing the measurement models in confirmatory factor analyses, we added covariates as predic…
Accelerometer-determined physical activity and self-reported health in a population of older adults (65-85 years): a cross-sectional study.
2013
Background The link between physical activity (PA) and prevention of disease, maintenance of independence, and improved quality of life in older adults is supported by strong evidence. However, there is a lack of data on population levels in this regard, where PA level has been measured objectively. The main aims were therefore to assess the level of accelerometer-determined PA and to examine its associations with self-reported health in a population of Norwegian older adults (65–85 years). Methods This was a part of a national multicenter study. Participants for the initial study were randomly selected from the national population registry, and the current study included those of the initi…
Social Ecological Model of Problem Gambling : A Cross-National Survey Study of Young People in the United States, South Korea, Spain, and Finland
2021
Problem gambling among young people is an emerging trend globally. The online environment in particular offers various possibilities for gambling engagement. This is the first cross-national survey study using the social ecological model to analyze problem gambling, especially in the online context. The study aimed to analyze how different social ecological spheres explain problem gambling. Participants were young people aged 15–25 in the United States (n = 1212), South Korea (n = 1192), Spain (n = 1212), and Finland (n = 1200). The South Oaks Gambling Screen (SOGS) instrument measured problem gambling. The regression models analyzed problem gambling with measures of intrapersonal, interper…
Benefit of hearing aid use in the elderly: the impact of age, cognition and hearing impairment
2018
Il beneficio protesico e il ruolo delle abilità cognitive, dell’età e del deficit uditivo nel paziente anziano.Questo studio analizza il beneficio protesico in un campione di soggetti anziani (n = 102, età media 81,1 anni), indagando il ruolo svolto dall’età, dal deficit uditivo e dalle abilità cognitive. Il beneficio protesico è stato valutato sia come miglioramento delle caratteristiche audiometriche con protesi (in termini di soglie tonali e soglie di percezione del parlato in quiete e nel rumore) sia come diminuzione della percezione della disabilità e dell’handicap dovuti alla ipoacusia. Sono state valutate diverse abilità cognitive, tra cui la memoria a breve termine, le funzioni esec…
Old and new immunophenotypic markers in multiple myeloma for discrimination of responding and relapsing patients: The importance of "normal" residual…
2014
Background Multiple myeloma is an incurable disease characterized by proliferation of clonal malignant plasma cells (CPCs), which can be immunophenotypically distinguished from polyclonal plasma cells (PPCs) by multiparameter flow cytometry (MFC). The utility of PPCs analysis in detecting prognostic and predictive information is still a matter of debate. Methods: we tested the ability of 11 MFC markers in detecting differences in the immunophenotype of CPCs and PPCs among patients in various disease stages; we verified if these markers could be associated with disease stage/response to therapy despite the role of clinical parameters. Results: significant changes in the expression of markers…
Association of ocular, cardiovascular, morphometric and lifestyle parameters with retinal nerve fibre layer thickness.
2017
BACKGROUND Glaucoma is a neurodegenerative disease, leading to thinning of the retinal nerve fibre layer (RNFL). The exact influence of ocular, cardiovascular, morphometric, lifestyle and cognitive factors on RNFL thickness (RNFLT) is unknown and was analysed in a subgroup of the Gutenberg Health Study (GHS). METHODS Global peripapillary RNFLT was measured in 3224 eyes of 1973 subjects (49% female) using spectral-domain optical coherence tomography (SD-OCT). The association of age, sex, ocular, cardiovascular, morphometric, lifestyle and cognitive factors on RNFLT was analysed using Pearson correlation coefficient and fitting a linear mixed model. RESULTS In the univariable analysis highest…
Are Morphological or Functional Changes in the Carotid Artery Wall Associated With Chlamydia pneumoniae, Helicobacter pylori, Cytomegalovirus, or Her…
2000
Background and Purpose —Chronic infection with Chlamydia pneumoniae , Helicobacter pylori , cytomegalovirus (CMV), and herpes simplex virus (HSV) has been implicated in the pathogenesis of atherosclerosis. The carotid intima-media thickness (IMT) can be taken to indicate early atherosclerosis, the presence of a carotid stenosis is a marker of a manifest carotid atherosclerosis, and an increase in arterial stiffness is used as marker of structural and functional changes in an atherosclerotic vessel wall. Methods —In 504 patients (75% men; mean age 62.9 [SD 10] years), we measured the IMT and the elastic pressure modulus (EP; n=445) of the common carotid artery and the prevalence of a intern…
Cortisol Awakening Response and Walking Speed in Older People.
2015
In older people, less diurnal variability in cortisol levels has been consistently related to worse physical performance, especially to slower walking speed (WS). The cortisol awakening response (CAR) is a discrete component of the hypothalamic-pituitary-adrenal axis that has been related to several health problems, such as cardiovascular disease and/or worse performance on executive function and memory. The relationship between the CAR and physical performance in older people is poorly understood. In this study, in 86 older people (mean age = 64.42, SD = 3.93), we investigated the relationship between the CAR and WS, a commonly used measure of physical performance in the older population t…
Sedentary behavior and perceived stress among adults aged ≥50 years in six low- and middle-income countries.
2018
Background:\ud Sedentary behavior and perceived stress are both negatively associated with physical and mental health. Little is known about the association between sedentary behavior and \ud perceived stress, and there is a particular paucity of data on people aged ≥50 years from low- and middle-income countries (LMICs). \ud Methods:\ud We analyzed cross-sectional, community-based data from 34,129 individuals aged ≥50 years [mean age 62.4 (SD=16.0) years, 52% females] from six LMICs. Perceived stress was assessed using the Perceived Stress Scale and time spent sedentary per day was self-reported. Multivariable linear regression analyses were conducted, adjusting for important socio economi…
