Weight loss intervention for young adults using mobile technology: design and rationale of a randomized controlled trial - Cell Phone Intervention for You (CITY).
Abstract
BACKGROUND: The obesity epidemic has spread to young adults, leading to significant
public health implications later in adulthood. Intervention in early adulthood may
be an effective public health strategy for reducing the long-term health impact of
the epidemic. Few weight loss trials have been conducted in young adults. It is unclear
what weight loss strategies are beneficial in this population. PURPOSE: To describe
the design and rationale of the NHLBI-sponsored Cell Phone Intervention for You (CITY)
study, which is a single center, randomized three-arm trial that compares the impact
on weight loss of 1) a behavioral intervention that is delivered almost entirely via
cell phone technology (Cell Phone group); and 2) a behavioral intervention delivered
mainly through monthly personal coaching calls enhanced by self-monitoring via cell
phone (Personal Coaching group), each compared to 3) a usual care, advice-only control
condition. METHODS: A total of 365 community-dwelling overweight/obese adults aged
18-35 years were randomized to receive one of these three interventions for 24 months
in parallel group design. Study personnel assessing outcomes were blinded to group
assignment. The primary outcome is weight change at 24 [corrected] months. We hypothesize
that each active intervention will cause more weight loss than the usual care condition.
Study completion is anticipated in 2014. CONCLUSIONS: If effective, implementation
of the CITY interventions could mitigate the alarming rates of obesity in young adults
through promotion of weight loss. ClinicalTrial.gov: NCT01092364.
