This is the Phase 2 pilot/feasibility randomized controlled trial of HALO (Health And Lifestyle Behaviors In Offspring), a parent-led behavioral intervention targeting a high-risk pediatric population (i.e., residing offspring ages 6-12; body mass index > the 70th and < 120% of the 95th percentiles of mothers with severe obesity) that is uniquely well-timed, when mothers are highly engaged in behavior change and losing weight during the first year following bariatric surgery.

|---|---|---|---|
| Treatment | Experimental | HALO is a mixed-delivery intervention (online learning, digital technologies, telehealth visits) co-designed with mothers that (a) uniquely tailors intervention content to integrate post-bariatric surgery guidelines to recommendations to reduce child obesity risk, (b) teaches mothers evidence-based parenting behaviors to support intergenerational lifestyle and home food environment changes, and (c) addresses unique barriers to family-level change identified by mothers post-bariatric surgery. |

| Enhanced Standard of Care | Active Comparator | The comparator group will receive monthly mailings of publicly available and age-appropriate handouts on healthy eating, physical activity, screen time, and healthy sleep habits |

| HALO | Behavioral | Health and Lifestyle Behaviors in Offspring, or "HALO" is designed for mothers who recently had bariatric surgery who have a school-aged child. HALO focuses on providing each mother with education and parenting strategies to improve her child's healthy lifestyle behaviors, such as her child's eating and physical activity, while she is engaged in her own lifestyle behavior change after bariatric surgery. |
| Measure | Description | Time Frame |
|---|---|---|
| Preliminary Efficacy - Change in child body mass index standardized for age/sex from baseline to 26 weeks (post-treatment) | Trained assessors will measure child height/weight using a standardized protocol. These measurements will be converted to body mass index (kg/m^2) and then standardized by child age and sex | baseline to 26 weeks (post-treatment) |
| Preliminary Efficacy - Change in child body mass index standardized for age/sex from baseline to 52 weeks (6-month follow-up) | Trained assessors will measure child height/weight using a standardized protocol. These measurements will be converted to body mass index (kg/m^2) and then standardized by child age and sex | baseline to 52 weeks (6-month follow-up post-treatment) |
| Measure | Description | Time Frame |
|---|---|---|
| Secondary - Change in child daily intake of total kcals, and kcals from red foods, sugar-sweetened beverages, and fruits and vegetables from baseline to 26 weeks (post-treatment) using a 3-day dietary recall | Child dietary intake (mother-reported) will be assessed by a registered dietician via 3 scheduled 24-hour phone recalls (2 weekdays, 1 weekend) over a 2 week period using a multiple pass method. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in maternal percent weight loss and body mass index from baseline to 26 weeks (post-treatment) | Trained assessors will measure mothers' weight and height using a standardized protocol which will be used to calculate maternal percent weight loss and body mass index (kg/m^2). | baseline to 26 weeks (post-treatment) |

Prior to sharing, all data will be de-identified in a HIPAA-compliant fashion. Data sets will be carefully reviewed to make sure that information such as age and sex cannot be used to gather additional information that could potentially identify individual subjects. All categorical demographic variables will be collapsed into categories large enough so that combinations of demographic categories for age, sex, geographic location, etc., will have 10 or more individuals in each cell. All modalities of data will be shared, including raw and aggregate data. Descriptors for all variables shared will be included to prevent misuse or confusion. Any analytical methods utilized to assess the data will be defined in shared formats.
