Clinical Trial Summary
Lowering sugar-sweetened beverage (SSB) consumption is a central component of lifestyle
behavior change aimed at preventing and managing obesity, yet effective reduction of SSB
intakes has been met with many challenges. While their palatability, accessibility,
publicity, affordability, and social acceptability contribute to frequent and sustained SSB
consumption, their caffeine and sugar content may further encourage continued intake.
Although adverse health consequences of excessive SSB consumption are well documented, the
extent to which their pleasant taste (due primarily to their sugar content) and
post-ingestive effects (due to their sugar and/or caffeine content) positively reinforce
consumption among children has not been elucidated. The purpose of this study is to conduct a
pilot intervention to examine the feasibility of removing caffeinated SSBs from the child
diet and to explore whether caffeinated SSB removal induces withdrawal symptoms in 8-11
(3rd-5th grade) year old children. Participants will be randomly assigned to replace their
usual caffeinated SSB consumption with either caffeinated SSBs, caffeine-free SSBs or
sparkling water provided by the study team for two weeks.
Description:
Sugar-sweetened beverages (SSBs) significantly contribute to sugar and calorie intakes, and
their consumption is associated with metabolic disease. Sweetened beverages also account for
the majority of pediatric caffeine consumption. It is well-established that habitual caffeine
use leads to dependence in adults and evidence for sugar dependence has been documented.
However, caffeine and/or sugar dependence related to sweetened beverage consumption has not
been evaluated, and determinants of their consumption among youth are severely understudied.
It is critical to elucidate whether they may be physiologically or psychologically dependent
on these beverages, particularly SSBs, which contain both caffeine and sugar.
The purpose of this study is to conduct a pilot study where caffeinated SSB's are replaced
with caffeinated SSBs provided by the study team (control) or with caffeine-free and
unsweetened alternatives (also provided by the study team) for 2 weeks, among children who
habitually consume caffeinated SSBs.
Lowering SSB consumption is a central component of lifestyle behavior change aimed at
preventing and managing obesity, yet effective reduction of SSB intakes has been met with
many challenges. While their palatability, accessibility, publicity, affordability, and
social acceptability contribute to frequent and sustained SSB consumption, their caffeine and
sugar content may further encourage continued intake. Although adverse health consequences of
excessive SSB consumption are well documented, the extent to which their pleasant taste (due
primarily to their sugar content) and post-ingestive effects (due to their sugar and/or
caffeine content) positively reinforce consumption among children has not been elucidated.
This is particularly important to study among children from low-income and minority
backgrounds, as these children have the highest rates of SSB intake and the highest
prevalence of obesity.
Specific Aims and Hypotheses:
1. Examine the feasibility of an intervention to remove caffeinated SSB from the child
diet. We hypothesize that caffeinated SSB avoidance will be feasible among children, but
that compliance will be lowest among those assigned to sparkling water, devoid of both
caffeine and sugar. Compliance with beverage assignments will be assessed using daily
online questionnaires and weekly dietary recalls.
2. Explore the extent to which caffeinated SSB removal induces withdrawal symptoms. We
hypothesize that replacement of caffeinated SSBs with caffeine-free SSBs, or sparkling
water will induce withdrawal symptoms compared to control (usual caffeinated SSB
consumption). Participants will complete a child-adapted version of the validated
Caffeine Withdrawal Symptoms Questionnaire (CWSQ) at baseline and daily (online) during
the intervention.
