title: The Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT) Program follow-up.
abstract: BACKGROUND
  The Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT) Program, is a community-based, cluster-randomised controlled trial of an obesity prevention intervention delivered to first-time parents of infants from age 4-20 months. Conducted from 2008 to 2010, the program had high uptake and retention and showed positive impacts on some dietary outcomes and television viewing. Funding was secured for a follow-up study of participants two and 3.5 years post intervention (at child ages ~3.5 and 5 years). The follow-up study aims to assess intervention effects, mediators and moderators of effects, and program cost-effectiveness over the longer term.
  
  
  METHODS
  The 492 families still enrolled in the Melbourne InFANT Program at intervention conclusion will be recontacted and renewed consent sought to participate in this follow-up study. No further intervention will occur. Home visit data collections will occur approximately two and 3.5 years post intervention. Main outcomes to be assessed include child body mass index, waist circumference, diet (3 × 24-hour recalls; food frequency questionnaire), physical activity (8 days ActiGraph accelerometer data; parent reported active play) and sedentary time (8days ActiGraph accelerometer and ActivPAL inclinometer data; parent reported screen time).
  
  
  CONCLUSIONS
  Follow-up of participants of the Melbourne InFANT Program at two and 3.5 years post intervention will allow assessment of longer term intervention effects, investigation of potential mediators and moderators of such effects, and economic evaluation of the longer term outcomes. This information will be valuable to researchers and policy makers in progressing the field of early childhood obesity prevention.
