- INTRODUCTION:The Job Demand-Control-Support (JDCS) model is commonly used to investigate associations between psychosocial work factors and employee health, yet research considering obesity using the JDCS model remains inconclusive.OBJECTIVE:This study investigates which parts of the JDCS model are associated with measures of obesity and provides a comparison between waist circumference (higher values imply central obesity) and body mass index (BMI, higher values imply overall obesity).METHODS:Contrary to common practice, in this study the JDCS components are not reduced into composite or global scores. In light of emerging evidence that the two components of job control (skill discretion and decision authority) could have differential associations with related health outcomes, components of the JDCS model were analysed at the subscale level. A cross-sectional design with a South Australian cohort (N = 450) combined computer-assisted telephone interview data and clinic-measured height, weight and waist circumference.RESULTS:After controlling for sex, age, household income, work hours and job nature (blue vs. white-collar), the two components of job control were the only parts of the JDCS model to hold significant associations with measures of obesity. Notably, the associations between skill discretion and waist circumference (b = -.502, p = .001), and skill discretion and BMI (b = -.163, p = .005) were negative. Conversely, the association between decision authority and waist circumference (b = .282, p = .022) was positive.CONCLUSION:These findings are significant since skill discretion and decision authority are typically combined into a composite measure of job control or decision latitude. Our findings suggest skill discretion and decision authority should be treated separately since combining these theoretically distinct components may conceal their differential associations with measures of obesity, masking their individual importance. Psychosocial work factors displayed stronger associations and explained greater variance in waist circumference compared with BMI, and possible reasons for this are discussed.

Short sleep, psychosocial work stressors, and measures of obesity: results from an Australian cohort study

Konferensbidrag (refereegranskat)abstract
- Introduction: Short sleep and workplace stress are both established risk factors for overweight and obesity, yet few studies have considered how these two factors may intersect. The aim of this study was to establish the associations between these two exposures and their relative associations with body mass index (kg/m2 ) and waist circumference (cm).Methods: A cross-sectional design sampled current employees (N=423) from an Australian cohort using a computer-assisted telephone interview and clinic-measured height, weight, and waist circumference. Short sleep (≤6h/ night) was reported by 25.8% of the participants. Psychosocial work stressors were defined using the Job Demand-ControlSupport (JDCS) model and calculated at the subscale level (psychological demands; skill discretion; decision authority; coworker support; supervisor support). General linear models were used to assess associations between short sleep, the JDCS subscales (split at median), and BMI and waist circumference.Results: Separate analyses identified short sleep and a lack of skill discretion at work as predictors of both BMI and waist circumference. Furthermore, when both predictors were entered in the same model, each was associated with elevated BMI (b=1.79, p=.003; b=1.08, p=.045) and waist circumference (b=4.20, p=.005; b=2.97, p=.028). Short sleep was also associated with high perceived psychological demands at work (b=1.81, p=.003). All models were adjusted for gender, age, work hours, blue vs. white collar job, and household income.Discussion: These findings indicate the importance of considering the interplay between short sleep and psychosocial work stressors, and their respective associations with measures of overweight Sleep Sci. 2019;12(Supl.3):1-75 26 and obesity. Further research using longitudinal data is needed to model potential mechanisms (e.g., behavioral and physiological). A novel feature was the subscale consideration of the prominent JDCS model of work stress. Advocacy for both improved habitual sleep (e.g., ≥7h/night) and job redesign to increase skill discretion at work may promote lower levels of overweight and obesity for employees.

- Leisure-time physical activity (LTPA) and dietary energy intake are two important health behaviours, which at too low or high levels respectively, are associated with overweight and obesity. This study explores associations between subscales of the Job Demand-Control-Support (JDCS) model, LTPA and dietary energy intake. A cross-sectional design sampled current employees (N=433) from a South Australian cohort using a computer-assisted telephone interview and a self-completed food frequency questionnaire. In analyses adjusted for sex, age, and sociodemographic variables, higher levels of skill discretion were associated with increased odds for attaining sufficient physical activity (OR=2.45; 95% CI=1.10-5.47). Higher levels of decision authority were associated with reduced odds (OR=0.43; 95% CI=0.20-0.93) for being in the highest tertile of daily energy intake. Higher scores for coworker support were associated with increased odds (OR=2.20; 95% CI=1.15-4.23) for being in the highest tertile of daily energy intake. These findings support the consideration of the individual JDCS subscales, since this practice may reveal novel associations with health behaviour outcomes, thereby presenting new opportunities to improve employee health and wellbeing.
