The Effect of Green Tea Consumption on the Body Mass Index, Blood Pressure, and Heart Rate of Operating Room Personnel

Obesity is one of the most crucial risk factors in the occurrence of non-communicable diseases. Its prevalence has increased even among health care personnel and could render them susceptible to a myriad of diseases, particularly cardiovascular disorders (CVDs). Diverse treatment methods have been devised in this regard, one of which is the consumption of green tea. Owing to this, the present study attempted to explore the effect green tea exerts on the body mass index (BMI), blood pressure, and pulse rate of operating room personnel.
The current before-and-after clinical trial was conducted on 24 operating room personnel at the Shahid Motahari Hospital in Isfahan, Iran, in 2015. After informed consent forms were obtained from the subjects, they were asked to consume 4 cups of green tea, containing 3 g of green tea leaves in 300 ml of boiled water at 80 ºC, daily for 8 weeks. Their BMI, blood pressure, and pulse rate were monitored before and after the consumption of green tea. Data analysis was carried out in SPSS software.
Findings: The results of the study demonstrated that systolic pressure and pulse rate had a considerable decrease after 8 weeks of consumption of green tea. Nevertheless, no effect was observed on BMI and diastolic pressure.
The consumption of green tea can cause a beneficial reduction in systolic blood pressure and pulse rate, and thus, improve the cardiovascular status.
