Caffeine Has Different Cardiovascular Effect on Boys, Girls

the MPR take:

Do boys and girls respond differently to caffeine?  Yes, says a new study published in the journal Pediatrics. To test these responses, researchers administered either placebo or two doses of caffeine to prepubertal and postpubertal boys and girls. Upon examining heart rate and blood pressure in both genders, a greater response to caffeine was seen in boys than in girls. Specifically in girls, a difference in response was seen depending on where the subject was in her menstrual cycle (decreases in heart rate in midfollicular phase; increases in blood pressure in midluteal phase).  More research will need to done to see what factors are influencing these different responses.
