2011
Christoph Alexander Rüst1, Beat Knechtle1,2, Patrizia Knechtle2, Ursula Barandun1, Romuald Lepers3, Thomas Rosemann11Institute of General Practice and Health Services Research, University of Zurich, Zurich, Switzerland; 2Gesundheitszentrum St Gallen, St Gallen, Switzerland; 3INSERM U887, University of Burgundy, Faculty of Sport Sciences, Dijon, FranceAbstract: The aim of this study was to investigate predictor variables of anthropometry, training, and previous experience in order to predict a half marathon race time for future novice recreational male half marathoners. Eighty-four male finishers in the ‘Half Marathon Basel’ completed the race distance within (me…
Gender, exercise, and health: A life-course cross-sectional study.
2020
The purpose of this study is to explore relationships between the practice of exercise, gender, and health, from adolescence to old age, testing the magnitude of gender differences throughout the life cycle in the practice of exercise of Spanish people. A cross-sectional study with 4,575 women and 4,334 men, aged 13-85 years, was conducted. The participants were assessed on the weekly hours they dedicated to the practice of exercise, masculine/instrumental and feminine/expressive traits, mental health symptomatology, and self-rated health). Univariate and multivariate analyses were performed in the age groups of adolescence, late adolescence, young adulthood, middle adulthood, and older age…
Perceived stress and smoking across 41 countries: A global perspective across Europe, Africa, Asia and the Americas
2017
Within recent years, there has been a seismic shift in smoking rates from high-income to low- and middle-income countries (LMICs). Evidence indicates that perceived stress may comprise a barrier for smoking cessation, but little is known about the association of perceived stress and smoking in LMICs. We conducted a cross-sectional, community-based study comprising 217,561 people [mean age 38.5 (SD = 16.1) years, 49.4% males]. A perceived stress score [range 2 (lowest-stress) 10 (highest-stress)] was computed from the Perceived Stress Scale. Multivariable logistic regression analyses were conducted. In the overall sample, a one-unit increase in perceived-stress resulted in a 5% increased odd…
Work strain in midlife and 28-year work ability trajectories
2011
We investigated the 28-year development trajectories of work ability among initially middle-aged male and female municipal employees and the association of perceived mental and physical work strain in midlife by work ability trajectory groups.The baseline data of the Finnish longitudinal study of municipal employees (FLAME) were collected in 1981 (N=6257) with follow-ups in 1985, 1992, 1997, and 2009. Work ability was assessed in all the waves as present perceived work ability relative to lifetime best. Altogether, N=2690 had work ability data in 1981 and 2009, and at least for one wave in between these years, and were included in group-based semi-parametric mixture modeling trajectory anal…
Physical activity and obesity mediate the association between childhood motor function and adolescent's academic achievement
2013
The global epidemic of obesity and physical inactivity may have detrimental implications for young people’s cognitive function and academic achievement. This prospective study investigated whether childhood motor function predicts later academic achievement via physical activity, fitness, and obesity. The study sample included 8,061 children from the Northern Finland Birth Cohort 1986, which contains data about parent-reported motor function at age 8 y and self-reported physical activity, predicted cardiorespiratory fitness (cycle ergometer test), obesity (body weight and height), and academic achievement (grades) at age 16 y. Structural equation models with unstandardized (B) and standardi…
Oxidative stress is associated with an increased antioxidant defense in elderly subjects: a multilevel approach.
2014
© 2014 Fonseca et al. Background: Studies of associations between plasma GSH-Px activity and cardiovascular risk factors have been done in humans, and contradictory results have been reported. The aim of our study was to assess the association between the scavenger antioxidant enzyme glutathione peroxidase (GSH-Px) activity in plasma and the presence of novel and classical cardiovascular risk factors in elderly patients. Copyright: Methods: We performed a cross-sectional study with baseline data from a subsample of the PREDIMED (PREvención con DIeta MEDiterránea) study in Spain. Participants were 1,060 asymptomatic subjects at high risk for cardiovascular disease (CVD), aged 55 to 80, selec…
The relationship between different settings of medical service and incident frailty
2018
Background: Some studies have reported a potential association between usual source of health care and disability, but no one has explored the association with frailty, a state of early and potential reversible disability. We therefore aimed to explore the association between older persons' self-reported usual source of health care at baseline and the onset of frailty. Methods: Information regarding usual source of health care was captured through self-report and categorized as 1) private doctor's office, 2) public clinic, 3) Health Maintenance Organization (HMO), or 4) hospital clinic/emergency department (ED). Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the…
Age identification in the framework of successful aging. A study of older Finnish people.
2003
A person-oriented approach was used in a study of age identification among community-dwelling older people. The study was based on 8-year follow-up data; 843 persons aged 65–84 were involved in the first phase of the study, and 426 persons aged 73–92, in the second phase. Loosely, on the basis of the distinction between successful, usual, and pathological aging (Rowe & Kahn, 1987, 1997), participants were grouped according to their self-ratings of cognitive and physical functioning as “Positive,” “Negative,” and “Others.” Participants possessing at least 4 out of the 5 criteria used as indicators of successful aging in the study (no illness or injury presenting problems in daily life, …
Impact of sociodemographic characteristics on cognitive performance in an elderly Sicilian population.
2002
<i>Objective:</i> To assess cognitive levels in an elderly Sicilian population and to evaluate the role of education and other sociodemographic characteristics in cognitive performance. <i>Background:</i> The pattern of cognitive performance in the elderly has not been investigated extensively in well-defined Italian populations. This study was conducted as part of a door-to-door survey of common neurologic disorders (the Sicilian Neuro-Epidemiologic Study project). <i>Methods:</i> Thirteen physicians administered an Italian version of the Short Portable Mental Status Questionnaire (SPMSQ) to all subjects aged 50 years or older who, on November 1, 1987, r…
Implementation of the Frailty Index in hospitalized older patients: Results from the REPOSI register
2018
Abstract Background Frailty is a state of increased vulnerability to stressors, associated to poor health outcomes. The aim of this study was to design and introduce a Frailty Index (FI; according to the age-related accumulation of deficit model) in a large cohort of hospitalized older persons, in order to benefit from its capacity to comprehensively weight the risk profile of the individual. Methods Patients aged 65 and older enrolled in the REPOSI register from 2010 to 2016 were considered in the present analyses. Variables recorded at the hospital admission (including socio-demographic, physical, cognitive, functional and clinical factors) were used to compute the FI. The prognostic impa…
