High blood pressure (HBP) is one of the leading causes of premature death worldwide. Currently, 1 in 3 adults has HBP. Recent studies have shown that caffeine leads to an acute increase of blood pressure after exposure, but the long-term effects of caffeine on blood pressure are unclear. Our study aimed to assess the correlation between caffeine intake during childhood/adolescence and blood pressure in adulthood using data collected in the Princeton Prevalence Study (PPS) and its follow-up 25 years after the original study. PPS subjects were children in the 1st through 12th grade who attended schools in the Princeton City School District in Ohio. Twenty-four-hour recall dietary data and blood pressure measurements were collected during PPS, and blood pressure was also measured at follow-up. Our analysis contained the 623 subjects who participated in both parts of the study. They were categorized into 3 groups according to their age during PPS: 6-9, 10-13, and 14-18 years old. Blood pressure measurements obtained during PPS and its follow-up were compared in each group between subjects with and without caffeine consumption during PPS. We did not observe any significant difference between the blood pressure of individuals who consumed caffeine during PPS and those who did not. These results suggest that caffeine consumption during childhood/adolescence is not associated with blood pressure in either childhood or adulthood. To further assess this correlation, we suggest the analysis of a shorter study with caffeine intake assessment through the duration of the study.
