Job demand and cardiovascular disease risk factor in white-collar workers.
TLDR
The results suggest that high job demand may be a risk factor of cardiovascular diseases.Abstract:
This study was conducted to determine whether job demand played a role as a risk factor of cardiovascular diseases by comparing changes of blood pressure, heart rate and rate pressure product (RPP) showing myocardial oxygen consumption (MVO2) according to levels of job demand. This cross-sectional study divided 177 male white-collar workers without a cardiovascular or metabolic disease according to their job demand and analyzed their body composition and results of graded exercise testing. There was no significant difference in height, body weight, body mass index (BMI), waist to hip ratio (WHR) and body fat percentage according to job demand. Maximal oxygen consumption (VO2max) and anaerobic threshold (AT) also did not show a significant difference. However, systolic blood pressures at the seventh and eighth stages over AT during exercise were significantly different and RPP was found to have a significant difference overall according to the job demand (p<0.05). These results meant that job demand affected systolic pressure in physical activities or at exercise intensity over AT and reduced energy efficiency of myocardium during physical activities. The results suggest that high job demand may be a risk factor of cardiovascular diseases.read more

TL;DR: Elevated serum uric acid concentration was strongly associated with obesity and hyperlipidemia in both men and women and indicated that, among hyperuricemia patients, patients should pay more attention to the possibility of cardiovascular complications.

The relationship between meeting of recommendations on physical activity for health and perceived work ability among white-collar workers
TL;DR: Meeting leisure-time physical activity recommendations (especially the criterion of vigorous physical activity) is significantly related to higher self-assessed ability to work among white-collar workers.

TL;DR: In this paper, the authors discuss the benefits and risks associated with physical activity and propose a general principles of exercise prescription for healthy populations with special consideration and environmental consideration, as well as a prescription for patients with chronic diseases and health conditions.

TL;DR: Suggestions to improve the assessment of behavioral interventions include more complete delineation of the physiological mechanisms by which such interventions might work; increased use of new, more convenient "alternative" end points for behavioral intervention trials; development of specifically targeted behavioral interventions (based on profiling of patient factors); and evaluation of previously developed models of predicting behavioral change.

TL;DR: Evidence from longitudinal studies suggests that chronic life stress may be causally linked to weight gain, with a greater effect seen in men, and stress-induced eating may be one factor contributing to the development of obesity.
