About

Obesity has been shown to be resistant to treatment in adults, adolescents, and in school age children, but not during early childhood. Yet knowledge on the effectiveness of early childhood treatment programs for obesity is still very limited, preventing the widespread implementation of such programs. The overarching purpose of this study is to evaluate the effectiveness of early treatment of childhood obesity. The investigators plan to perform a carefully-designed randomized controlled trial that will evaluate different treatment options offered to families with children with obesity, organized within the healthcare system and followed up for at least 1 year post-baseline. Participants will be children aged 4-6 years (N=180) with obesity and their parents. This study will facilitate a close examination of key treatment components and mechanisms of change. Results from this study will lead to better healthcare options for obesity treatment during childhood and ultimately to the prevention of obesity later in life from a public health perspective.

Full description

The proposed randomized controlled trial has four specific aims: Specific Aim #1: PARENTING OR LIFESTYLE? To determine the effectiveness of two obesity treatment conditions: 1) parent training (n=90) and 2) treatment as usual focused on lifestyle changes (n=90). The two treatment conditions will be evaluated with respect to child weight status (BMI SDS; primary outcome), psychosocial and metabolic health, lifestyle choices, and family functioning (secondary outcomes). Specific Aim #2: OPTIMAL LENGTH OF TREATMENT AND FOLLOW-UP? To understand the influence of treatment duration we will compare the effectiveness of the parent training program administered for 10 wks only and for 10 wks plus additional booster sessions at 8-week intervals for the following year. All groups will be followed up for at least one year post-baseline. Specific Aim #3: TO START AT AGE 4,5 OR 6? To assess the influence of child age at the start of treatment on the treatment outcomes. Specific Aim #4: MEDIATORS AND MODERATORS? To determine whether changes in targeted parenting skills (such as limit setting, monitoring and problem-solving) will mediate child obesity outcomes by examining all treatment groups. In addition, we will examine moderators of intervention effects (e.g. socioeconomic status (SES), parental weight status, and depression).

Treatment focus - Parenting vs lifestyle
Experimental group
Description:
To determine the effectiveness of two obesity treatment interventions: 1) parent training group (n=90) and 2) standard treatment with focus on lifestyle (n=90). The two treatment conditions will be evaluated with respect to child weight status (BMI SDS; primary outcome), psychosocial and metabolic health, lifestyle choices, and family functioning (secondary outcomes). This design will allow us to assess whether a program targeting only parents and focusing on parenting practices will result in better outcomes than treatment as usual emphasizing lifestyle changes.
Treatment:
Behavioral: Parent training group
Behavioral: Standard treatment with focus on lifestyle
Length of treatment
Experimental group
Description:
To understand the influence of treatment duration by comparing the effectiveness of two obesity treatment interventions: the parent training group administered for 12 wks only (n=45) and the parent training group with booster sessions which include additional booster sessions at 8-week intervals for the following year (n=45). Thus we will randomize families to either a group with booster sessions or without. This design will allow us to evaluate if prolonged care is necessary to maintain intervention effects, or if a 12-week program is equally effective.
Treatment:
Behavioral: Parent training group
Behavioral: Parent training group with booster sessions
