Effect of Cardiorespiratory Fitness on Risk of Sudden Cardiac Death in Overweight/Obese Men Aged 42 to 60 Years
2018
The purpose of this study was to examine the subject and combined associations of cardiorespiratory fitness (fitness) and body mass index (BMI) with the risk of sudden cardiac death (SCD) in middle-aged men. This prospective study was based on a population sample of 2,357 men aged 42 to 60 years, who were followed up in the Kuopio Ischemic Heart Disease cohort study. Fitness was directly measured by peak oxygen uptake (VO2peak) during progressive exercise testing to volitional fatigue. Participants were divided into 4 groups (fit-normal weight, unfit-normal weight, fit-overweight/obese, and unfit-overweight/obese) based on the median values of fitness and BMI. A total of 253 (10.7%) SCDs oc…
Family violence and mental health in a sample of Finnish health care professionals : the mediating role of perceived sleep quality
2019
Background Family violence (FV) is a prevalent health issue around the world and health care services have an important role in both recognizing and treating the consequences of violence. However, FV experiences among health care professionals themselves have not been investigated much. We also lack specific knowledge on the associations between FV and mental health. Aim The purpose of the study was to investigate the prevalence and effects of FV in a sample of Finnish health care professionals. In addition to analysing direct connections between different types of FV and mental health, the mediating effect of sleep quality was also taken into account. Methods The study followed a cross‐sec…
Physical Activity, Sleep, and Symptoms of Depression in Adults - Testing for Mediation
2019
Abstract Purpose: Physical activity, sleep problems, and symptoms of depression contribute to overall well-being. The factors are reciprocally associated, but the nature of these associations remains unclear. The present study examined whether sleep problems mediated the association between physical activity and depressive symptoms. Methods: The eligible population (n = 3596) consisted of adults from the ongoing, population-based Cardiovascular Risk in Young Finns Study started in 1980. Participants’ leisure-time physical activity was assessed with physical activity index (2007) and sleep problems with Jenkins’ Sleep Questionnaire in 2007 and 2011. Depressive symptoms were measured using mo…
Effects of alertness management training on sleepiness among long-haul truck drivers : a randomized controlled trial
2018
Education is a frequently recommended remedy for driver sleepiness in occupational settings, although not many studies have examined its usefulness. To date, there are no previous on-road randomized controlled trials investigating the benefits of training on sleepiness among employees working in road transport. To examine the effects of an educational intervention on long-haul truck drivers' sleepiness at the wheel, amount of sleep between work shifts, and use of efficient sleepiness countermeasures (SCM) in association with night and non-night shift, a total of 53 truck drivers operating from southern Finland were allocated into an intervention and a control group using a stratified random…
Fracture Mechanics of Collagen Fibrils: Influence of Natural Cross-Links
2013
AbstractTendons are important load-bearing structures, which are frequently injured in both sports and work. Type I collagen fibrils are the primary components of tendons and carry most of the mechanical loads experienced by the tissue, however, knowledge of how load is transmitted between and within fibrils is limited. The presence of covalent enzymatic cross-links between collagen molecules is an important factor that has been shown to influence mechanical behavior of the tendons. To improve our understanding of how molecular bonds translate into tendon mechanics, we used an atomic force microscopy technique to measure the mechanical behavior of individual collagen fibrils loaded to failu…
Combined effects of shiftwork and individual working time control on long-term sickness absence: a prospective study of finnish employees
2014
Objective To investigate whether the effects of shiftwork on long-term sickness absence vary according to the level of individual working time control (WTC). Methods A representative sample of Finnish employees (1447 men and 1624 women) was combined with a register-based follow-up. A negative binomial model was used in the analysis of long-term sickness absence days. The results were adjusted for various background and work-related factors. Results Individual WTC decreased long-term sickness absence. The higher rate of sickness absences in shiftwork was mainly due to the lower level of WTC. Working time control decreased sickness absence equally in day work and shiftwork. Conclusions The ne…
Does organized sport participation during youth predict healthy habits in adulthood? A 28-year longitudinal study
2018
Health behaviors in youth can predict the same behaviors later in life, but the role of sport participation in predicting healthy lifestyle habits is unclear. This study aimed to investigate the association between participation in organized youth sport and adult healthy lifestyle habits. Data from the longitudinal Cardiovascular Risk in Young Finns Study (YFS) with a 28-year follow-up were used. The participation in sport-club training sessions was self-reported by 9-18-year-olds in 1983 and 1986 (n = 1285). During 2011, participants (aged 37-43-year old) reported their smoking status, alcohol consumption, fruit and vegetable consumption, and physical activity. Odd ratios (OR) were calcula…
Is It Good To Be Good? Dispositional Compassion and Health Behaviors
2018
Background Despite the documented importance of dispositional compassions for a range of health-related outcomes, its role in predicting health behaviors remains unclear. Purpose This study examined the associations between dispositional compassion and three domains of health behavior, including physical activity, alcohol use, and smoking. Methods The participants (N = 1,279–1,913) were from the Finnish population-based Young Finns study. We collected self-reports of compassion in 1997 and 2011 and health behaviors in 2001, 2007, and 2011. In addition, an objective pedometer measure of physical activity was collected in 2011. Linear and logistic regression models were fitted to estimate the…
Temperament and Early Intentions to Retire
2019
Abstract Objective: To examine associations between temperament traits and early retirement intentions. Methods: In the Northern Finland Birth Cohort 1966, we analyzed early retirement intentions at the age 46 according to Cloninger temperament traits at the age 46 (n = 4409) and at the age 31 (n = 3226). Ordinal logistic regression analyses were used. Adjustments were made for marital status, education, work type, job satisfaction, perceived health, and mental health problems. Results: 11% of men and 9% of women had strong retirement intentions. Especially higher harm avoidance was associated with higher early retirement intentions in both sexes at the age of 46. A similar pattern of resul…
In vivo fascicle behavior of the flexor hallucis longus muscle at different walking speeds.
2017
Ankle plantar flexor muscles support and propel the body in the stance phase of locomotion. Besides the triceps surae, flexor hallucis longus muscle (FHL) may also contribute to this role, but very few in vivo studies have examined FHL function during walking. Here, we investigated FHL fascicle behavior at different walking speeds. Ten healthy males walked overground at three different speeds while FHL fascicle length changes were recorded with ultrasound and muscle activity was recorded with surface electromyography (EMG). Fascicle length at heel strike at toe off and at peak EMG activity did not change with speed. Range of FHL fascicle length change (3.5-4.5 and 1.9-2.9 mm on average in s…
