A clinical study evaluating Placebo Administration first, Low Caffeine Administration first (1mg/kg body weight), and 1 other intervention for Healthy. Completed, enrolled 101 participants across 1 site.
Detailed 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.
