In the recent article “Ideal Cardiovascular Health and Job Strain: A Cross-Sectional Study from the Amazon Basin”, by Muniz et al., the authors proposed that cardiovascular health (CV) is influenced by the workplace conditions. The study involved 478 employees, which had wide access to health information, from a University in the Amazon Basin, Brazil. Researchers used a validated version of the Job Demand Control Model (JDC model) questionnaire to assess work stress. The study is an innovative one, since it is the first one to explore this hypothesis in the Amazon Basin. The authors found a high prevalence of poor CV, which was mainly associated with a poor diet and obesity, suggesting that participants with high job strain are more likely to have eating disorders, resulting in weight gain.

Weight gain and hormonal alterations have been observed in patients with sleep disturbances, such as obstructive sleep apnea. Obstructive sleep apnea is a very prevalent sleep disorder that leads to the development of metabolic syndrome, cardiovascular outcomes and contributes to systemic inflammation.
