Community Active and Healthy Families
Condition: Obesity, Childhood
MeSH terms: Obesity; Pediatric Obesity
Study type: Interventional

Summary: 
      To address childhood overweight disparities among Latino children in immigrant families a
      pilot trial of a community-based obesity treatment program, Community Active and Healthy
      Families (AHF), among 5-12 year old overweight and obese Latino children in immigrant
      families using pre/post design will be conducted.

      The hypothesis is that children participating in Community-AHF will demonstrate a reduction
      in child body mass index as measured by %BMIp95 (primary outcome) and improved diet physical
      activity behaviors (secondary outcomes) at intervention completion compared with
      pre-intervention
    

Detailed description: 
      To address childhood overweight disparities among Latino children in immigrant families a
      pilot trial of a community-based obesity treatment program, Community Active and Healthy
      Families (AHF), among 5-12 year old overweight and obese Latino children in immigrant
      families using a pre/post design will be conducted.

      As this is a pilot study, we will not be powered to detect statistically significant
      differences pre- and post- intervention. We will measure the average change in %BMIp95
      between baseline and completion of the Community-AHF active phase. Without a counterfactual
      (control group) we will not be able assign responsibility to Community-AHF for any observed
      improvements. Change in %BMIp95 across the study period will provide data to test our
      hypotheses and will inform statistical power analyses for a subsequent trial. This pre- and
      post-intervention data is ideal for generating sample size estimates for a larger randomized
      control trial in the same population.

      We will conduct within-individual analyses for each outcome of interest. We will only analyze
      participants who contribute pre and post measures in order to avoid biases that can occur
      when analyses are conducted with all available data. For each outcome for which a participant
      contributes pre and post measurements, we will calculate pre and post means, standard
      deviations, differences in means and the p-value of the difference. We will conduct
      preliminary analyses of outcomes according to subgroups defined by rate of attendance at
      intervention sessions. If adequate data are available, we will explore the possibility of a
      nonresponse analysis.
    

Intervention name(s): Community Active and Healthy Families
Intervention type(s): Behavioral
Intervention description(s): Community-AHF will consist of eight, semimonthly 2-hour group appointments. Community-AHF sessions will target two areas: 1) Practical information regarding importance of healthy behaviors, and 2) Problem-solving skills to overcome barriers to improving diet and increasing physical activity and other related healthy behaviors. Each session covers specific objectives, includes a number of complementary activities and provides participants with take-home materials to facilitate behavior change.
Community-AHF will be delivered by a nurse and a Community Health Worker (CHW) trained by a consultant nutritionist and study investigators. The CHW will contact families between group sessions to discuss challenges and successes regarding lifestyle changes.
Intervention model: Single Group Assignment
