SUMMARY:

Introduction: Hospital environment working is known for presenting unhealthy features that affect the health of its workers - features which have currently been intensified due to the COVID-19 pandemic. Objective: To investigate the association between occupational stress, dietary pattern and cardiovascular risk factors in workers at a private hospital in the Recôncavo da Bahia, considering the context of the COVID-19 pandemic. Methods: This work consists of three different studies. Study 1 is a systematic review carried out through searches in PUBMED, WEB OF SCIENCE, EMBASE, SCOPUS, CINAHL, PSCYINFO and LILACS databases, from July to October 2020, and updated in October 2021. Observational studies that evaluated occupational stress as exposure through the Job Content Questionnaire (JCQ), and that investigated its influence on worker's health were included, regardless of the year of publication. The risk of bias of the included studies was assessed using the Research Triangle Institute Item Bank on Risk of Bias and Precision of Observational Studies. Studies 2 and 3 are longitudinal studies conducted with 218 workers of legal age (>18 years old) from a private hospital in the Recôncavo of Bahia. A semi-structured questionnaire was used to collect sociodemographic, occupational, anthropometric, dietary, lifestyle and health data. The main exposure of Studies 2 and 3 was occupational stress assessed through the JCQ and classified according to the Demand-Control Model; additional exposures were other occupational characteristics considered to be work stressors. The outcomes of Study 2 were nutritional status, according to Body Mass Index (BMI), Waist Circumference (WC) and Body Fat Percentage (BF%), self-perceived health and cardiovascular risk factors. The outcomes of Study 3 were dietary patterns identified through factor analysis. Statistical analyses for Study 2 included McNemar's chi-square test and Wilcoxon test, as well as binomial logistic regression models; whereas those for Study 3 included McNemar's chi-square test and Generalized Estimating Equation models. Results: Study 1 - For the qualitative analysis, the search strategy retained 42 studies, including 182187 participants. Among retained studies, the influence of occupational stress was examined in cardiovascular diseases (CVD) (n=10), as primary outcome, and metabolic syndrome (MS) (n=5), dyslipidemias (n=15), and obesity (n=22), as additional outcomes. Systematized evidence showed that high levels of occupational stress appear to be associated with CVD and MS. However, its influence in dyslipidemias and obesity remain unclear. Meta-analyses of these clinical conditions showed significant associations between occupational stress and CVD (OR 1.34; 95%CI 1.15-1.57) and MS (OR 2.75, CI95% 1.97-3.83), but no significant effect between stress at work and dyslipidemias and obesity. Study 2 - during the COVID-19 pandemic, there was an increase in high occupational stress levels, obesity (according to BMI, WC and BF%) regular or poor self-perception of health and presence of cardiovascular risk factors when compared with the pre-pandemic period. No association was observed between change in occupational stress and health outcomes. However, increased amount of shift work was related to increased BMI in the overall sample (OR 3.79, CI95% 1.40-10.30), and in health workers (OR 11.56; CI95% 2.57-52.00). Study 3 - During the pandemic, participants reported increased occupational stress, shift work and weekly workload, when compared with the pre-pandemic period. Also, three dietary patterns were identified in these two moments. No association was observed between changes in occupational stress and dietary pattens. However, COVID-19 infection was related with the changes in pattern A (0.647, IC95%0.044; 1.241, p=0.036) and changes in the amount of shift work was related to changes in pattern B, (0.612, IC95%0.016; 1.207, p=0.044). Conclusions: The findings of Study 1 demonstrated an adverse effect of occupational stress on CVD and MS. However, when considering Studies 2 and 3, no association was observed between stress at work and the health outcomes studied; the only association observed was between the stressors of hospital work, the increase in BMI and the changes in A and B worker's dietary patterns. This evidence can help strengthen labour policies to ensure adequate working and health conditions for hospital workers in the context of the COVID-19 pandemic.
