Objective:
To determine the blood pressure in a native Tzotzil population from the state of Chiapas, Mexico.
Methodology:
Cross-sectional study on a Chenalho Tzotzil population from Chiapas, Mexico, from August to December 2015, aged between 20 to 60 years-old. Patients with diabetes mellitus and hypertension were excluded, as well as pregnant patients. The sample size was 205, using as sample basis, the list of patients that went to the healthy patient wellness clinic. The systolic and diastolic pressures were measured by the same person. The measurement was performed on the right arm with the patient seated, five minutes after coming into the clinic, without performing any physical activity beforehand. It was measured with an Adex™ mercury column sphygmomanometer. The statistical analysis includes mean and percentages, as well as their confidence intervals.
Results:
The mean diastolic blood pressure found was 68.73mmHg (95% CI,-67.63-69.69), with a diastolic of 103.65mmHg (95% CI; 102.24-105.06) and a mean arterial pressure 80.37mmHg (95% CI, 79.35-81.39).
Conclusion:
The arterial blood pressure in a Tzotzil native population of Chiapas, Mexico is lower than that reported in the scientific literature.

Measurement of Blood Pressure
Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
