Abstract

OBJECTIVES:

Energy drinks contain large amounts of caffeine. Their effects on adolescent well-being are poorly known. We examined the relationship of energy drink consumption with health complaints and late bedtime among 13-year-olds.

METHODS:

A classroom survey was conducted on all 7th graders in the Helsinki metropolitan region, Finland (73 % responded; n = 9446). Logistic regression analysis and structural equation modeling (SEM) were used.

RESULTS:

The prevalence of health complaints increased as energy drink consumption increased from non-consumers to several times/day. Late bedtime (≥11 PM) increased correspondingly. Those consuming energy drinks several times/day exhibited increased odds of experiencing daily health complaints compared with non-consumers: headache OR (adjusted) = 4.6 (2.8-7.7), sleeping problems OR = 3.6 (2.2-5.8), irritation OR = 4.1 (2.7-6.1), tiredness/fatigue OR = 3.7 (2.4-5.7), and late bedtime OR = 7.8 (5.7-10.9). In SEM, energy drink consumption had a direct effect on health complaints and late bedtime and an indirect effect on health complaints via late bedtime.

CONCLUSIONS:

Energy drinks, late bedtime, and health complaints form a behavior pattern that is worth considering in schools, home and clinical settings when adolescents complain about headaches, problems with sleeping and corresponding symptoms.
