May 8, 2017 updated by: Elizabeth Kuhl, Wayne State University
The purpose of this study is to examine the feasibility, acceptability, and preliminary efficacy of a community and home-based preschool obesity intervention for families enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Very few studies have targeted weight control in preschoolers even though the prevalence of overweight has exceeded 20% in this age-group for the past decade. Also concerning is that few studies have focused on preschoolers from low-socioeconomic (SES) backgrounds despite persistent obesity-related socioeconomic disparities. Family-based, behavioral interventions appear a promising model for treatment of obesity in early childhood. However, the dissemination potential of these programs is unclear as they have primarily been tested with families from middle-to-upper class backgrounds and within research settings. Identifying effective approaches to weight control for preschoolers from low-SES backgrounds that can be delivered in community settings is imperative to reducing the pediatric obesity epidemic. The proposed study will begin to address this critical gap by completing the second phase of developing a community-based preschool weight control intervention for families enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The proposed study is significant because we specifically target preschool weight control in a high-risk population and because delivery of our program within the WIC program is conducive to its dissemination. Based upon our formative work, and existing preschool obesity programs, we have developed a 14-session, family-based preschool weight control intervention (FBWC) that emphasizes experiential learning and is delivered in the WIC and home settings. Seventy-two overweight and obese preschool-caregiver dyads will be randomized in a 2:1 ratio to receive FBWC or to continue with standard of care at WIC (WSOC). The primary study aims are to a) examine the feasibility and acceptability of FBWC and b) explore the preliminary efficacy of FBWC compared to WSOC on reduction in preschooler BMI-z-score and caregiver BMI from baseline to post-treatment (4-months) and 7-months (3-month follow-up). An exploratory aim is to evaluate lifestyle and behavioral indicators of intervention success. This study is innovative because: 1) very few studies have examined obesity intervention in preschoolers, 2) we target weight control in a high-risk group that has been underrepresented in the preschool obesity treatment outcome literature, 3) our intervention is community-based, and 4) we emphasize experiential learning as a strategy for achieving lifestyle behavior change and weight control.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Family-Based Weight Control Intervention
Families will receive the FBWC
Behavioral: Family-Based Weight Control
Families randomized to the intervention condition will receive a 4-month, 14-session behavioral weight control intervention targeting obesity reduction in preschoolers and caregivers. Within the program, 9 sessions will be group-based and held at WIC and 5 sessions will be individual visits (4 home-based and 1 at a food market where the family shops). The intervention includes teaching behavioral weight loss, child behavior management, and life skills (e.g., budgeting and time management ) via experiential learning to assist families with implementing diet and activity recommendations for pediatric and adult weight management.
Other Names:
  • FBWC
No Intervention: Control
Families will continue with standard of care at WIC

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
