Parents and children will measure body weight on a study-provided digital scale following instructions provided by study team.

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.

Reciprocal influence (parent response as mediator for child; child response as mediator for parent) will be operationalized as adult or child weight loss.

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.

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.

Reach (participation rates and representativeness) will be assessed across recruitment methods. Participation rates will be calculated in multiple ways to include: 1) the percentage of individuals on lists who respond and 2) the percentage of eligible respondents who enroll. Enrolled participants will be classified by recruitment method according to participant self-report of how they heard about the study,. Representativeness will be assessed by comparing demographics (age/grade, sex, race/ethnicity, BMI where available) between enrolled participants and non-participants including 1) potential participants on recruitment lists and 2) those who are screened but do not enroll. In addition, the investigators will assess the impact of nurse engagement/leadership on participant reach and attendance.

Self-reported physical activity will be collected from the exercise vital sign. A subset of participants will have physical activity measured using a study-provided Garmin activity device, a consumer wearable that will automatically detect and track activity such as walking, running, and cycling. This device will measures steps.

Child diet will be parent reported using the Children's Eating Habits Questionnaire-Food Frequency Questionnaire section (CEHQ-FFQ). We are interested in the frequency of red foods ("junk" foods) and fruits/vegetables. A subset of participants will complete this more frequently beginning at 13 weeks.
