Caffeine has different post-puberty effects on boys and girls: Study (Fotolia)


 

A new study from the University at Buffalo found caffeine affects boys and girls differently after puberty.

Previous studies have shown that caffeine increases blood pressure and decreases heart rate in children, but this study focused on the effects of caffeine on each gender before and after puberty.

The study examined heart rate and blood pressure before and after administration of a placebo and two doses of caffeine in pre-pubertal and post-pubertal boys and girls.

"We found an interaction between gender and caffeine dose, with boys having a greater response to caffeine than girls," associate professor Jennifer Temple said.

The study showed that while caffeine reactions in both genders were identical before puberty, after puberty caffeine consumption in boys caused a greater decrease in heart rate and increase in blood pressure. The study also found girls had a greater cardiovascular response to caffeine during certain phases of their menstrual cycle.

The study will be published in the July 2014 edition of the journal Pediatrics.
