Clinical Trial Summary
Despite the negative consequences to maternal-child health from women gaining too much weight
during pregnancy, up to 62% of overweight and obese women gain more pregnancy weight than is
recommended. This project will establish the efficacy of Goals for Reaching Optimal Wellness
(GROWell), an mHealth tool for achieving appropriate pregnancy weight gain and promoting
postpartum weight loss among women who enter pregnancy overweight or obese. GROWell will fill
a gap in research and clinical care by providing a validated, standalone mHealth tool for
weight control during pregnancy and postpartum, which is a currently lacking resource.
Description:
Research attempts to prevent excess gestational weight gain, defined as gaining more weight
during pregnancy than Institute of Medicine (IOM) guidelines for prepregnancy body mass index
(BMI), have largely been unsuccessful. Roughly 62% of overweight and 45% of obese women still
gain more weight than recommended, increasing risk for postpartum weight retention. Few
mobile health (mHealth) interventions have been trialed to address pregnancy-associated
weight gain, which is a missed opportunity. Adult women are high users of technology for
general and pregnancy-specific health information seeking and sharing. To fill this gap, the
long-term goal of this research is to disseminate into clinical practice a standalone mHealth
tool that is effective for overweight and obese pregnant women to achieve gestational weight
gain within IOM recommendations and return to prepregnancy weight after childbirth. The goal
of this application is to test GROWell: Goals for Reaching Optimal Wellness, an innovative,
mHealth tool based on Self-regulation Theory that investigators designed in pilot work to
achieve appropriate gestational weight gain and safe postpartum weight loss. The
investigators propose a blinded, randomized controlled trial to test the efficacy of GROWell
compared to an attention control also developed in a pilot. Investigators will recruit 480
women ages 18-44 with prepregnancy BMI 25-<40 and 10-16 weeks gestation of a singleton,
uncomplicated pregnancy. Block randomization based on BMI, race, and recruitment clinic will
be used to assign participants equally to arm 1, GROWell (n=240), or arm 2, the attention
control (n=240). Upon study enrollment and through 6 months postpartum, GROWell participants
will receive daily text messages that provide tailored education, problem-solving skills, and
support to aid their personalized dietary goals. Once weekly, participants self-monitor
overall adherence to their goals using text messages that prompt them to report on how they
did in the past week. When users respond to this prompt, they immediately receive a text with
tailored feedback on their adherence and long-term progress toward their goals. Control
participants will receive weekly texts that provide personalized self-care, pregnancy, labor,
delivery, and early infancy education. The specific aims are to: (1) Compare the efficacy of
GROWell to the attention control in reducing the proportion of women who gain excess
gestational weight based on IOM guidelines (>25 lbs for overweight and >20 lbs for obese)
controlling for demographics, parity, physical activity, diet quality, and
depression/anxiety; and (2) Compare the efficacy of GROWell to the attention control in
reducing postpartum weight retention at 6 months post-birth as measured by the proportion of
women who are within 5% of their prepregnancy weight, controlling for demographics, parity,
physical activity, diet quality, breastfeeding, and depression/anxiety. This research
addresses PA 18-135 (Maternal Nutrition and Pre-pregnancy Obesity) and will provide an
innovative, evidence-based, standalone mHealth tool to reduce excess gestational weight gain
and postpartum weight retention among overweight and obese women, currently an unavailable
resource.
