Pediatric Obesity, Weight Loss
Conditions
Brief summary
The purpose of this study is to assess whether providing a parent-only group program before providing a parent and child group program works better than the parent and child group program alone.
Detailed description
The goal of this project is to determine if an adult intervention followed by a family-based program (iAmHealthy Parents First) will result in a larger percentage of weight loss in parents and children compared to solely a family-based program (iAmHealthy). Furthermore, the investigators aim to discover if administering iAmHealthy Parents First will improve dietary intake, physical activity, and weight-related quality of life among parents and children when compared to iAmHealthy. Parent/child dyads will be recruited from rural elementary schools, medical clinics, and organizations across Kansas and neighboring states.
Interventions
BEHAVIORALiAmHealthy Parents First
iAmHealthy Parents first is a 3-month adult obesity treatment program targeting the unique needs of adults with school-age children. Following the iAmHealthy Parents First program, these dyads will take part in a 6-month family-based healthy lifestyles program.
BEHAVIORALiAmHealthy
The iAmHealthy group will receive newsletters for three months. Following this period, these dyads will take part in a 6-month family-based healthy lifestyles program.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percent weight change in parents and BMIz (BMI z-score) in children | Baseline, 3 months, 9 months | Parents and children will measure body weight on a study-provided digital scale following instructions provided by study team. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mediator: Attendance | Baseline, 3 months, 9 months | Group and individual session attendance (percent of sessions) will be tracked on REDCap, a secure, web-based application designed exclusively to support data capture for research studies. |
| Mediator: Reciprocal modeling | Baseline, 3 months, 9 months | Reciprocal influence (parent response as mediator for child; child response as mediator for parent) will be operationalized as adult or child weight loss. |
| Moderator: Family functioning | Baseline, 3 months, 9 months | Family functioning will be measured using the Family Assessment Device (FAD). This is the gold-standard measure of structural, organizational, and transactional characteristics of families including general family functioning (core scale of interest) and 6 additional subscales: affective involvement, affective responsiveness, behavioral control, communication, problem solving, and roles. This questionnaire will be completed by adults. The FAD is scored by adding responses of each scale (1 - 4) and dividing by the number of items in each scale (between 6 - 12). The higher the overall score, the worse the level of family function. |
| Moderators: Genetic casual attributions | Baseline, 3 months, 9 months | Genetic casual attributions will be measured using a a 2-item Likert scale that assesses perceived genetic role for weight status and potential for weight loss. This will be completed by adults. Those who endorse completely or mostly for the role of genes in weight loss will be characterized as having "high genetic attribution" for weight status. |
