Is Obesity Associated With Adverse Workers' Compensation Claims Outcomes?

Workplace wellness programs targeting weight outcomes in men: A scoping review

Workplaces have been identified as a priority setting for the delivery of wellness programs to address risk factors for overweight and obesity. Men in particular may benefit greatly from these types of programs as they are typically harder to engage in health promotion. A scoping review was performed to provide an overview of interventions that have been implemented within the workplace that target weight outcomes in men. A searched of six electronic databases (Medline, Embase, CINAHL, Scopus, Cochrane Database of Systematic Review, and Business Source Ultimate) was conducted from January 2010 to August 2020. Of the 2191 articles identified, 25 were included. The majority took place in North America or Europe (72%). Over half (n = 17, 68%) utilized both a nutrition and physical activity component. Thirteen of the 19 articles (68%) that reported weight as an outcome showed the program to be efficacious in reducing weight. Overall, only seven articles were solely focused on an all-male population. Workplace wellness programs targeting weight outcomes in men have been conducted to some extent, with majority being successful in reducing weight. However, there is a need for more randomized controlled trials (RCTs), long-term follow-up, and male-only programs.

Satisfaction with life and the risk of occupational injury

Background

Occupational injuries increase burden on society as well as personal health. Low satisfaction with life may not only increases the risk of occupational injuries directly, but also influences other factors that increase the risk of occupational injury. Along with previous studies on the risk of occupational injury, we sought to explore the relationship between satisfaction with life and occupational injury.

Methods

The study participants were 6234workers health screened at a university hospital in Incheon. Information on occupational injury and satisfaction with life scale (SWLS) was obtained in a self-report format. Participants were allocated to one of four SWLS groups; the dissatisfied group, the slightly dissatisfied group, the slightly satisfied group, and the satisfied group. The analysis was performed using the chi-square test primarily and by logistic regression adjusted for potential confounders.

Results

In men, the un-adjusted and adjusted odds ratios (ORs) of low satisfaction with life (SWLS< 20) were 1.98(CI1.55-2.53) and 1.81(CI 1.41-2.32), respectively. When the SWLS were divided into four groups, the adjusted ORs of the slightly satisfied (20-25), slightly dissatisfied(15-19), and dissatisfied(≤14) groups were 1.21, 1.72, and 2.70, respectively. That is ORs tended to increase linearly with decreasing SWLS score (p for trend < 0.001). In women, this relation was of borderline significance at best.When subjects were dichotomized based on SWLS scores, for males, the cured and adjusted RRs of occupational injury in the low satisfaction with life group were1.91 (95% CI: 1.50-2.42) and 1.66 (95% CI: 1.30-2.13), and for females, the adjusted-RR was marginally significant (1.67; 95% CI: 0.93-2.99).When subjects were divided into four groups by SWLS scores, adjusted RRs tended to increase linearly with decreasing SWLS score for males (slightly satisfied: 1.18, 95% CI: 0.77-1.82; slightly dissatisfied: 1.65, 95% CI: 1.08-2.52; dissatisfied: 2.22, 95% CI: 1.44-3.42; p for trend < 0.001) and for females (slightly satisfied: 1.17, 95% CI: 0.42-3.30; slightly dissatisfied: 1.56, 95% CI: 0.56-4.36; dissatisfied: 2.38, 95% CI: 0.84-6.74; p for trend = 0.040).

Conclusions

This study suggests that the risk of occupational injury was higher in workers not satisfied with life, and indicates attention to satisfaction with life may promote the health of workers.

Study of the effects of nesfatin-1 on gastric function in obese rats

AIM

To investigate the effects of nesfatin-1 on gastric function in obese rats.

METHODS

The obese rat model was induced by a high-fat diet. The gastric emptying rate and gastric acid secretory capacity of the rats were determined after treatment with different drug concentrations of nesfatin-1 and administration routes. Based on this, the expression of H+/K+-ATPase was measured using RT-PCR and western blot to preliminarily explore the mechanism of gastric acid secretion changes.

RESULTS

Body weight, body length, and Lee’s index of the rats significantly increased in the high-fat diet-induced obese rat model. Two hours after lateral intracerebroventricular injection of nesfatin-1, the gastric emptying rate and gastric acid secretory capacity of rats decreased. Four hours after injection, both were restored to normal levels. In addition, the expression of H+/K+-ATPase decreased and moved in line with changes in gastric acid secretory capacity. This in vivo experiment revealed that intracerebroventricular injection of nesfatin-1, rather than intravenous injection, could suppress gastric function in obese rats. Moreover, its effect on the gastric emptying and gastric acid secretory capacity of rats is dose-dependent within a certain period of time.

CONCLUSION

Through this research, we provide a theoretical basis for further studies on nesfatin-1, a potential anti-obesity drug.
