Association of the the Burnout syndrome cardiovascular risk and in Mexican workers

Introduction
In Mexico, the cardiovascular diseases caused in 2007 36.6% of total deaths. In the working population, the psychosocial risks would have an important role for cardiovascular diseases production. Among the stress-related problems, has been described that the Burnout syndrome would play a negative effect in worker´s cardiovascular health.
This study objective was to analyze the association between the Burnout syndrome and the level of cardiovascular risk in a group of Mexican workers.

Methods
This is a cross sectional study of 1,368 workers from Mexico City (842 women and 526 men). All the workers were previously informed and sign in an informed consent letter. The CESQT, JCQ and Health-History questionnaires were used. Blood pressure, weight, height, hip and waist circumference measurements were performed, and serum lipids levels were analyzed. A burnout-exposure index using the CESQT score and worker´s seniority in the position was built. To estimate workers´ risk to develop a cardiovascular disease during the next 10-years the Framingham equation was use. Data was analyzed using the SPSS statistical package (Ver.15) and the Chi2, Kruskall-Wallis and Logistic Regression tests were used.

Results
Severe and high Burnout subgroups had a significantly higher prevalence of perceived bad health, high waist/hip index, high Total-cholesterol and High LDL-cholesterol. Severe and high Burnout had also higher diastolic and systolic pressure, higher BMI and Triglycerides. The severe Burnout subgroup had the highest CV 10y-risk, 7.62%, and after controlling by sex, age and education and other psychosocial factors, the increase of the systolic and diastolic pressures and Burnout had a significant association, (OR=1.13, CI95%, 1.04-1.24).

Discussion
This study shows that the risk of developing a cardiovascular diseases related to the Burnout is relevant, a 13% increased risk of having high blood pressure. Presence of Burnout in workers brings negative effects on workers’ performance and in their cardiovascular health.
