OBJECTIVE: To estimate the association between night-shift work and high cardiovascular risk. METHODS: Cross-sectional study carried out with 211 workers of both genders, aged between 30 and 64 years, working on the health campus of a public university in the state of Minas Gerais, Brazil. Night-shift work was defined as a work shift between 7 pm and 7 am, and high cardiovascular risk was calculated based on the Framingham score. The association between night-shift work and high cardiovascular risk was estimated by the prevalence ratio (PR) and its 95% confidence interval (95% CI) after adjusting for potential confounding factors, calculated by Poisson regression. RESULTS: Night-shift work was performed by 38.4% of the individuals, and high cardiovascular risk was diagnosed in 28% of the sample. Hypertension was more prevalent among night-shift compared with day-shift workers (p < 0.05). In the bivariate analysis, night-shift work, passive and high job strain categories at the demand-control scale, work time > 120 months, schooling > 9 years, family income > 6 minimum wages, level 2 abdominal obesity, and triglyceride levels > 150 mg/dL were associated with high cardiovascular risk (p < 0.05). After multivariate analysis, night-shift work remained independently associated with high cardiovascular risk (PR = 1.67; 95% CI = 1.10-2.54). CONCLUSION: The prevalence of high cardiovascular risk was 67% higher among night-shift workers. This association should be considered when discussing the promotion of workers' health regarding changes in the work process.
