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, the study will not be powered to detect statistically significant differences pre- and post- intervention. The investigators will measure the average change in %BMIp95 between baseline and completion of the Community-AHF active phase. Without a counterfactual (control group) the investigators 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.
The investigators will conduct within-individual analyses for each outcome of interest. The investigators 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, the investigators will calculate pre and post means, standard deviations, differences in means and the p-value of the difference. The investigators will conduct preliminary analyses of outcomes according to subgroups defined by rate of attendance at intervention sessions. If adequate data are available, the investigators will explore the possibility of a nonresponse analysis.
