medical students who are eligible and consent to the study will be included in
the research study. The research will be for the duration of 8-10 weeks keeping
in mind not to disturb the academic curriculum of first year medical students.
Variables and data collection:
This will be in accordance to methods followed by Nahla

Measurements: After completing the questionnaire, measurements
will be taken as described by D’Agostino et al. 20. Measurements
will be taken by the principal investigator with the help of a trained
laboratory technician and his guide. The measurements include:
and height: Both will be obtained from a lightly clothed student.
The weight of the
participants will be measured using a calibrated weighing scale to the nearest
0.5 kg with the participant not wearing shoes.
The height will be taken
using a stadiometer to the nearest 0.5 cm with the participant standing upright
with the heel, buttock and upper back along the same vertical plane.
pressure (BP) measurement: It will be done while the student in the sitting
position after 4 minute of rest. Systolic and diastolic blood pressure is
identified at the beginning of the first and the fifth phase of the Korotkoff
sounds using a mercury sphygmomanometer applying the appropriate cuff on the
right arm 20.
Three consecutive readings
of blood pressure will be taken following a 4 min rest to allow the
participants vitals return to their at-rest values. The blood pressure will be
read to the nearest millimeter of mercury with the participant seated, and a
mean reading will be calculated from the 3 readings.
Hypertension is defined as
systolic BP of 140 mmHg or more and/or diastolic of 90 mmHg or more, according
to the7th Joint National Committee of High BP (JNC-7) 21.
Pre hypertension is
defined as a systolic BP of 130–139 and/or a diastolic BP of 85–89, according
to the JNC-7 21.
Mass Index (BMI): It will be calculated by dividing weight in kilograms by the
square of height in meters. BMI is divided into normal (
