The Wildcat Wellness Coaching Trial: Home-based Obesity Prevention and Health Promotion in Children and Adolescents
Female children (aged 8-13 years) will be recruited through posted flyers, newspaper ads,
and word of mouth in the Manhattan, KS area. After laboratory assessment, recruited
participants will be randomly assigned to either healthful eating and physical activity
skills coaching or general health education coaching intervention conditions. For both
conditions, research assistants will serve as wellness coaches and deliver 12 intervention
sessions in the home of each participating child.
Assessments will be completed at baseline, intervention end (3 months), and follow-up (6
months), comprising biomedical and psychosocial measures. Biomedical measurements to be
obtained include:
- body composition (DEXA, tetrapolar bioimpedance, body mass index, waist circumference)
- blood pressure (automated sphygmomanometer),
- pulmonary function tests (forced expiratory flow in 1-sec, forced vital capacity,
forced expiratory flow at 25-75% of vital capacity),
- unstimulated whole (mixed) saliva passive drool to detect markers of inflammation,
- and physical activity levels (7-day accelerometry).
Psychosocial measurements include:
- fruit and vegetable consumption (Child Dietary Questionnaire)
- self efficacy,
- enjoyment
- quality of life (Peds QL).
Inclusion criteria are:
- being female
- aged 8-13 years
- with parental consent,
- residing within a 40-minute drive
- being available for 12 home coaching visits and three lab assessments.
Exclusion criteria are
- having developmental delay or psychiatric problems,
- any illness, injury, condition, or disease that would prevent participation in
moderate-to-vigorous physical activity,
- taking weight-altering medications
- participating in any other health behavior change program.
The objectives of this study are to determine
- whether both types of the home-based coaching interventions are feasible
- whether the healthful eating and physical activity skills coaching intervention is more
efficacious, relative to the general health education coaching group, in preventing
increases in body fat percentage, body mass index percentile, waist circumference,
systolic and diastolic blood pressure, and sedentary behavior
- whether the healthful eating and physical activity skills coaching intervention is more
efficacious, relative to the general health education coaching group, in facilitating
increases in quality of life, moderate-to-vigorous physical activity, enjoyment of
physical activity and fruit and vegetable consumption, and self-efficacy for physical
activity and fruit and vegetable consumption.
We hypothesize that the research project will be successful in recruiting and retaining
participating families, training research assistants to deliver the intervention components,
and that both of the coaching conditions will be well received and appreciated by
participating families. We hypothesize that the healthful eating and physical activity
skills coaching intervention will be more effective than the support coaching condition in
preventing increases in blood pressure, airway dysfunction and adiposity. We expect that
both intervention conditions will show improvements to pediatric quality of life measures,
but that the healthful eating and physical activity skills coaching intervention will be
more effective than general health education coaching condition in increasing physical
activity, physical activity enjoyment and self efficacy, fruit and vegetable consumption,
and fruit and vegetable enjoyment and self-efficacy.

Obesity is associated with increased chronic disease risk, and therefore poses a major
public health problem (Lobstein et al., 2004). In 2011, the Centers for Disease Control and
Prevention estimated that obesity affects about 12.5 million children and teens, or 17% of
the US population. This is a marked increase from the ~5% rate of obesity found in this
population in the late 1960s. Barlow (2007) points out that the complexity of obesity
prevention lies less in the identification of target health behaviors, and much more in a
process of influencing families to change behaviors when habits, culture, and environment
promote less physical activity and more energy intake.
Obesity prevention interventions may not be effective or sustainable without impacting home
environments (Rosenkranz & Dzewaltowski, 2008). Conwell et al. (2010) suggest that
home-based programs may offer significant advantages over center-based programs by offering
better accessibility and convenience. Wellness coaching has shown promise for improving
health behaviors related to chronic disease (Lawn & Schoo, 2010), but no published study has
used a wellness coaching childhood obesity prevention model in the home environment.
The primary aim of this trial is to determine whether the home-based wellness coaching
delivery model is feasible as an obesity prevention intervention strategy in the community
setting. The secondary objective is to determine the comparative effectiveness of the two
wellness coaching interventions.
