Family Matters Intervention

Официальное название

Reducing Childhood Obesity Using Ecological Momentary Intervention (EMI) and Video Feedback at Family Meals

Обзор

The proposed study is a 12-month, individual randomized controlled trial (RCT). The main aim of the study is to decrease cardiovascular disease risk (BMI percentile, neck circumference) and improve child diet quality in children ages 5-10 years old by increasing family meal quality (i.e., dietary intake, interpersonal atmosphere) and quantity (i.e., frequency of family meals) via innovative technology (i.e., ecological momentary intervention (EMI), video feedback) and partnerships with primary care and Community Health Workers (CHWs).

Подробное описание

The RCT has the following three arms: (1) Ecological Momentary Intervention (EMI); (2) EMI + HV + Video feedback (virtual); (3) EMI + HV + Video feedback (hybrid). Delivery of the intervention will last 6 months for each family, with a 6-month post-intervention evaluation visit. All arms will receive EMI family meal tips via smartphones for 16 weeks. Arms 2 and 3 will also receive 16 weeks of in-home training (arm 2 will be virtual, arm 3 will be hybrid virtual/in-home), with 8 weeks (every other week) in-home education visits with a CHW focused on family meal quality and quantity and family meal preparation activities and 8 weeks "Try it Yourself" activities that reinforce the messages and skills taught by a CHW. Additionally, Arms 2 and 3 will receive video feedback from family's video-recorded family meals by a CHW focusing on family behaviors related to family meal quality and quantity. (EMI, in-home training, and video-feedback will occur during the same 16-week period.) After families have completed 16 weeks of the intervention, a 8-week maintenance phase will ensue. Having a maintenance phase is an evidence-based intervention component and will provide incrementally less support to families to build self-efficacy and increase sustainability of new behaviors. Over time, participants will receive less study support to evaluate if participants have internalized healthful behaviors. During the maintenance phase EMI meal tips will be reduced to only the days in which parents report their highest stress levels for all arms. The study will last 12 months, with three assessment time points including, baseline, 6 months (i.e., post-intervention) and 12 months.

Children ages 5-10 and family members (i.e., parent/primary caregiver, siblings) from low-income and diverse households (i.e., African American, Asian, Hispanic, Native American, White) - who are at high risk for cardiovascular disease - will be recruited for the study. Theory informs the intervention study design, research questions and related hypotheses, methods, measurement, and analysis. Family Systems Theory drives the decision to direct the intervention at the "family unit" to increase the likelihood of individual and family-level weight and weight-related behavior change and sustainability. Additionally, partnerships with existing community-based healthcare systems and CHWs will be utilized to reach participants in community settings.

This study utilizes innovative and research-informed intervention components (i.e., in-home visiting, EMI, video-feedback) to increase the likelihood of intervention effectiveness and sustainability.

Specific Aims of the Intervention Include:

• Aim 1 (Primary Outcomes): Conduct a three-arm RCT comparing EMI, EMI+HV, and EMI+HV+Video Feedback in diverse children ages 5-10 and their families to test the hypotheses that:

Hypothesis 1: BMI percentile and neck circumference will decrease and diet quality will increase in children in the EMI+HV+Video Feedback hybrid arm compared to children in the EMI or virtual-only arms.

• Aim 2 (Secondary Outcomes): Examine intervention effects on familial, parental, and sibling factors.

Hypothesis 1: Family meal quality and quantity will increase in households with children in the EMI+HV+ Video Feedback hybrid arm compared to children in the EMI or virtual arms.

Hypothesis 2: Controlling feeding practices (e.g., restriction) will decrease and coping skills will increase in parents in the EMI+HV+Video Feedback hybrid arm compared to parents in the EMI or virtual arms.

Hypothesis 3: BMI percentile will decrease in siblings in the EMI+HV+Video Feedback hybrid arm compared to siblings in the EMI or virtual arms.

• Aim 3: Examine cost effectiveness and feasibility of intervention implementation in primary care.

Hypothesis 1: The BMI z-score and neck circumference reduction resulting from the intervention will be cost-effective.

Вмешательства

• Поведенческое In-home Visits and Food Preparation Activities
  Families will participate in eight in-home education activities. The visits will focus on family meal quality (dietary, interpersonal) and quantity (meal frequency) factors found in prior studies to be associated with child weight and weight-related behaviors. Eight of the visits (every other week) will be delivered by a CHW and will last 90 minutes. Additionally, a family meal food preparation activity will occur to help support families in learning skills to increase family meal quality and qu
• Поведенческое Ecological Momentary Intervention
  Parents will receive daily EMI messages regarding suggestions for increasing meal quality/quantity via a smartphone application, based on the stress level and source of stress they reported earlier in the day. Specifically, parents will receive two push notifications in the morning to report their stress level and type/source of stress (e.g., work, children, finances). Then, based on the reported stress level and source of stress, parents will be texted tips/ideas for carrying out a nutritionall
• Поведенческое Feedback on Video-recorded Family Meals
  Parents will video-record and upload via their cellphone one family meal every other week, which will be watched by intervention staff. Using Motivational Interviewing, CHWs will give specific feedback on how to adapt negative mealtime behaviors and provide reinforcement for positive behaviors seen in the videos, based on a validated interpersonal coding tool called the Iowa Family Interaction Rating Scales (IFIRS). Additionally, feedback will be given on the dietary healthfulness of the meal, b
• Поведенческое Maintenance
  After 16 weeks, EMI family meal tips for all arms will be reduced to only the days in which parent's report their highest stress levels. Stress profiles will be created for each parent in order to tailor the EMI family meals tips to days in which they experience their highest levels of stress. For example, during the 16-weeks of EMI, a parent may report their highest stress levels on Tuesdays and Thursdays. The stress profile that would be created for the parent during the maintenance phase woul

Критерии участия

STUDY INCLUSION CRITERIA

The inclusionary criteria used to select participants for the proposed study includes:

• Boys and girls (n=500) ages 5-10 years old who attend a primary care clinic (e.g., pediatrics, family medicine) in Minneapolis or St. Paul metro area, Minnesota or Denver metro area, Colorado and their primary caregiver (e.g., mother, father, grandparent) and any other family members (e.g., sibling, cousin).
• Must eat ≤3 family dinner meals per week. Research shows that youth who have more than three family meals per week are less likely to be obese/high risk for cardiovascular disease ten years later. Thus, families who report three or fewer family meals per week will be recruited to optimize the potential for change in family meal frequency. Families will focus on the family dinner in the intervention to improve their family meal quality and quantity. This decision is based on: (1) Family Systems Theory, which indicates that change in one setting (e.g., family dinner) will generalize to other settings (e.g., breakfast, lunch, snacks).
• Child with age and sex adjusted BMI ≥75th percentile (no upper limit).
• One of the following race/ethnicities: African American, Asian, Hispanic/Latino, Native American, Asian American, or White. In order to examine racial/ethnic differences in study hypotheses, equal numbers of children per racial/ethnic group (total=500) will be recruited.
• Parent and family members who speak English or Spanish.
• Not expected to move within the next two years.

STUDY EXCLUSION CRITERIA

The exclusionary criteria used to exclude participants from the proposed study includes:

• Children with medically necessary dietary restrictions.
• Non-custodial parents, who the child does not live with more than 50% of the time.
