Effect of caffeinated beverages on university students? body mass index and blood glucose level
Abstract
Caffeine is generally consumed all over the world and legitimately recognized as a psychoactive
ingredient in many beverages and considered a drug. The penalty area of this research was to assess
how much college students are dependent on caffeine drinks and to identify knowledge and attitude of
students toward the effects of caffeinated beverages on their health. Also, our research aimed to
measure the effects of caffeinated beverages on some medical parameters before and after 2 hours of
drinking. An authorized survey was distributed haphazardly to 221 students aged between 17 and 22
years. The survey was performed using a pre-validated 15 items questionnaire. Some medical
parameters as body mass index, glucose level, and blood pressure were measured. Out of 217 students
in the study, the majority of them (98.2%) drank caffeinated beverages in the form of coffee drinks with
23.96%, tea drinks by 11.1%, energy drinks (14.7%), carbonated drinks (34.6 %) and 15.7 % of them
drinking all caffeinated beverages. Furthermore, 76.0% of them think caffeine addiction is a health issue.
Additionally, caffeinated beverages have antagonistic physiological effects on the level of blood glucose
and blood pressure after two hours of consumption (P<0.001). Finally, the highest percent of the
overweight and obese students were shown in carbonated drinks consumption group then in energy
drinks consumption. Consumption of caffeine-containing drinks in higher doses has undesirable effects
on health, so self-control and surveillance are necessary for daily intake.
