Work-related physical and psychosocial risk factors cluster with obesity, smoking and physical inactivity

Gendered Impact of Layoffs on Body Weight Trajectories in Transitional China: A Life Course Perspective 1993-2015

Layoffs can have lasting effects on the bodyweight trajectories of both genders. However, prior studies usually overlook the nuanced gender differences in health impacts. This study investigates the differential impact of layoffs from State-Owned Enterprises in China on body mass index (BMI) trajectories in men and women over a span of two decades. Our results indicate that being laid-off was associated with higher BMI at mid-age and accelerated BMI growth in women, contrasting with a slower BMI growth in men as they aged. The diverging trends were primarily driven by women and men who were back on the job market and re-employed. Women with post-layoff childcare responsibilities had the least healthy mid-life BMI, and a faster BMI growth compared to their job retainer counterparts. This study emphasizes the importance of considering gendered life course perspectives to understand the health impacts of job loss.

Evaluation of clinical aspects of obesity among undergraduate healthcare students- a cross-sectional study at King Saud University, Riyadh, Kingdom of Saudi Arabia

BACKGROUND

Obesity among healthcare students (HCs)is a growing concern that needs to be addressed. The purpose of this study was to evaluate the knowledge, awareness, perceptions, practice, and preparedness of obesity, and associated factors among undergraduate HCs.

METHODS

A cross-sectional study was conducted from December 2023 to March 2024 using an online prevalidated questionnaire, to assess clinical aspects of obesity.Simple random sampling was applied for data collection from nursing, emergency medical services (EMS), and pharmacy students at Saudi University, Riyadh Saudi Arabia. All data were analyzed using statistical package for social science (SPSS).

RESULTS

A total of 456 HCs participated in this study. Among those 68% believed eating high carbohydrates, fats, and sugars leads to obesity. At the same time, 52.2% and 57.2% were aware that smoking and stress can contribute to obesity. On the other hand, 41.9% live a healthy lifestyle and 38.65% engage in physical activity to control their obesity. The demographic variables such as age (p = 0.0001), gender (p = 0.0001), professional classification (p = 0.0001), presence of chronic diseases (p = 0.0001), history of weight loss treatment (p = 0.0001) and body mass index (BMI) (p = 0.0001) were significantly associated with knowledge of obesity(p = 0.001). Similarly, students' age (p = 0.001), presence of chronic diseases (p = 0.004) history of weight loss treatment (p = 0.0001), BMI (p = 0.001), and active status (p = 0.0001) were significantly associated with the perception of the obesity.

CONCLUSION

Undergraduate HCs possess a good understanding of the clinical prospects of obesity. They know its causes, risks, and treatment options. Additionally, they are well-prepared to support individuals in managing their weight through lifestyle modifications and psychological counseling.

An urgent call to address work-related psychosocial hazards and improve worker well-being

Work-related psychosocial hazards are on the verge of surpassing many other occupational hazards in their contribution to ill-health, injury, disability, direct and indirect costs, and impact on business and national productivity. The risks associated with exposure to psychosocial hazards at work are compounded by the increasing background prevalence of mental health disorders in the working-age population. The extensive and cumulative impacts of these exposures represent an alarming public health problem that merits immediate, increased attention. In this paper, we review the linkage between work-related psychosocial hazards and adverse effects, their economic burden, and interventions to prevent and control these hazards. We identify six crucial societal actions: (1) increase awareness of this critical issue through a comprehensive public campaign; (2) increase etiologic, intervention, and implementation research; (3) initiate or augment surveillance efforts; (4) increase translation of research findings into guidance for employers and workers; (5) increase the number and diversity of professionals skilled in preventing and addressing psychosocial hazards; and (6) develop a national regulatory or consensus standard to prevent and control work-related psychosocial hazards.

The contribution of work and health-related lifestyle to educational inequalities in physical health among older workers in Germany. A causal mediation analysis with data from the lidA cohort study

OBJECTIVES

The objective of the study was to investigate the contribution of work factors and health-related lifestyle to educational inequalities in physical health among older workers in Germany by applying causal mediation analysis with longitudinal data.

METHODS

Data from the German lidA study was used. 2653 persons (53% female, 47% male) aged 46 (born 1965) and 52 (born 1959) at baseline were followed up for seven years with exposure and outcome assessments in 2011 (t0), 2014 (t1) and 2018 (t2). The total effect of education on physical health was decomposed into a natural direct effect (NDE) and a natural indirect effect (NIE) by using a sex-stratified causal mediation analysis with an inverse odds weighting approach. Baseline health, partner status and working hours were entered as a first set of mediators preceding the putative mediators of interest. All analyses were adjusted for age and migrant status.

RESULTS

Independent of the first set of mediators, work factors explained 21% of educational inequalities in physical health between low and high educated women and 0% comparing moderate versus high educated women. The addition of health behaviors explained further 26% (low vs. high education) and 20% (moderate vs. high education), respectively. Among men, net of the first set of mediators, work factors explained 5% of educational inequalities in physical health between low and high educated and 6% comparing moderate versus high educated persons. Additional 24% (low vs. high education) and 27% (moderate vs. high education) were explained by adding health behaviors to the models.

CONCLUSIONS

To reduce educational inequalities in physical health among older workers in Germany, interventions to promote healthy behaviors are promising. Improving working conditions is likely an important prerequisite.

Psychosocial hazards play a key role in differentiating MSD risk levels of workers in high-risk occupations

OBJECTIVES

Workplace management practices targeting risk of musculoskeletal disorders (MSDs) fail to reflect evidence that risk is affected by psychosocial as well as physical hazards. To promote improved practices in occupations where MSD risk is highest, better information is needed on how psychosocial hazards, combined with physical hazards, affect risk of workers in these occupations.

METHODS

Survey ratings of physical and psychosocial hazards by 2329 Australian workers in occupations with high MSD risk were subjected to Principal Components Analysis. Latent Profile Analysis of hazard factor scores identified different combinations of hazards to which latent subgroups of workers were typically exposed. Survey ratings of frequency and severity of musculoskeletal discomfort or pain (MSP) generated a pre-validated MSP score and its relationship with subgroup membership was analysed. Demographic variables associated with group membership were investigated using regression modelling and descriptive statistics.

RESULTS

Analyses identified three physical and seven psychosocial hazard factors and three participant subgroups with differing hazard profiles. Profile group differences were greater for psychosocial than physical hazards, and MSP scores out of 60 ranged from 6.7 for the low hazard profile (29% of participants) to 17.5 for the high hazard profile (21%). Differences between occupations in hazard profiles were not large.

CONCLUSIONS

Both physical and psychosocial hazards affect MSD risk of workers in high-risk occupations. In workplaces such as this large Australian sample where risk management has focused on physical hazards, actions targeting psychosocial hazards may now be the most effective way to reduce risk further.

Surgery for Obesity and Weight-Related Diseases Changes the Inflammatory Profile in Women with Severe Obesity: a Randomized Controlled Clinical Trial

INTRODUCTION/PURPOSE

Obesity increases significantly every year worldwide. Since 1980, the prevalence of individuals with obesity has practically doubled. Obesity plays an important role in the pathophysiology of diseases that arise from a complex interaction of nutritional, genetic, and metabolic factors, characterizing a chronic inflammatory state. This study aimed to verify the systemic inflammatory response through the analysis of IGF-1, IL-23, and resistin levels and the lipid profile in severely obese women undergoing surgery for obesity and weight-related diseases.

MATERIALS AND METHODS

This randomized controlled clinical trial includes female patients clinically diagnosed with severe obesity with an indication for bariatric surgery.

RESULTS

In the initial evaluation, no significant difference was observed between the control (CG) and bariatric surgery (BSG) groups. The weight, BMI, systolic and diastolic blood pressures, total cholesterol, LDL, HDL, total non-HDL cholesterol, and glucose in BSG patients showed a significant change after surgery. Pre- and post-surgery levels of resistin, IGF-1, and IL-23 showed a significant difference in the BSG group, but only IL-23 was changed after 6 months in the CG.

CONCLUSION

The results of this study confirmed that weight loss induced by surgery for obesity and weight-related diseases improved the lipid profile and reduced the chronic inflammatory status in women with severe obesity.
