Brief Summary

Caffeine use is on the rise in America, and one of the most popular sources is soda. Among youth ages 8-16, caffeine consumption has increased by over 70% in the past 30 years. Few studies have examined the role of hormones in caffeine consumption within this age group. The purpose of the current experiment was to determine the effect of caffeine on children 8 and 9 compared to those 15 and 16 years of age. The investigators were looking at the effect of puberty on the consumption of caffeine as well as the effect that the caffeine has on the body (for example: heart rate, blood pressure) and cognitive function.

Outcome Measures

Primary Outcomes (2)

  • Peak Heart Rate After 2 mg/kg of Caffeine

    Heart rate measurements were taken every 10 minutes, following 1 minute of rest with an automated Welch Allen Blood Pressure Cuff. We have reported the data as the peak heart rate after 2 mg/kg.

    Heart rate was collected every 10 minutes for 60 minutes after the dose of caffeine.

  • Peak Systolic Blood Pressure

    Blood pressure measurements were taken every 10 minutes, following 1 minute of rest with an automated Welch Allen Blood Pressure Cuff. We have reported the peak heart rate after the 2 mg/kg dose of caffeine.

    Blood pressure was assessed every 10 minutes for 60 minutes after caffeine was administered.
