Abstract
Participation in regular physical activity (PA) has numerous health benefits including reduced risk of all-cause
mortality,1-7 cardiovascular disease,8-12 diabetes,13-16 and cancers of the breast17-19 and colon,20-23 as well as
energy balance.24 However, only 54% of U.S. adults meet national guidelines of expending > 1000 kcals/week
through PA,25 and as few as 10% meet guidelines when objective assessments of PA are used.26 Thus, there
is a need to improve adherence to PA programs using innovative approaches. Economic incentives have been
shown to be powerful motivators for behavior change and for improving health outcomes.28-37 While there is
evidence suggesting the general efficacy of incentive programs for increasing PA,38 research has not yet
demonstrated the optimal format for incentive programs. Nonetheless, spurred by organizational incentives
(i.e., tax breaks) provided by the Affordable Health Care Act, major insurance companies are now offering
economic incentives for regular attendance at fitness facilities in the absence of empirical support. Thus, we
propose to conduct an RCT to examine the efficacy of the exercise incentive program currently offered by
three major US insurance companies39-41 consisting of a $200 rebate on fitness facility membership fees for at
least 50 confirmed visits to the fitness facility (maximum 1/day, verified by objective swipe-card data) over 6
months. In the context of the RCT, we will also compare the insurance-based standard incentive program to a
second, loss-frame incentive condition in which the same incentive schedule is used, but with participants told
(and reminded during the course of the program) that $200 of their membership fee is being held and will be
returned or forfeited depending on whether they use the gym at least 50 times in the next 6 months. The
proposed RCT will be conducted in a community setting at the Greater Providence YMCAs. Aim 1. Conduct an
RCT (N=330) comparing (a) the widely used insurance-based Standard incentives program (n=110), (b) a
Loss-framed incentive program (n=110), and (c) no-incentive Control (n=110). Each participant will be enrolled
for two consecutive 6-month periods for a total of 12 months per participant. The primary outcome will be
number of visits to the fitness facility. Secondary outcomes will include total moderate-to-vigorous PA (MVPA)
over 7-day periods at 3-month intervals through accelerometers and self-reported MVPA. We hypothesize that
the two incentive conditions will result in higher attendance at the YMCA and more PA, with the Loss-framed
incentive program outperforming the Standard insurance-based program. Aim 2. Examine habit formation and
anticipated regret as putative mediators and household income and age as moderators of the incentive-based
programs. Aim 3. Conduct a within trial cost-utility analysis from a societal perspective to quantify (a) the
incremental costs per quality-adjusted life year (QALY) gained, (b) cost per change in YMCA attendance, and
(c) cost per incremental change in PA. We will additionally apply a productivity model to estimate the economic
impact of the intervention on future household and labor force participation.
