Plain English Summary

Background and study aims:
Current fruit and vegetable consumption in children is low. There are few studies which promote fruit and vegetable intake, which have targeted children in child care, despite the fact that younger children are more likely influenced by adults in an eating environment. The objective of this pilot study is to assess whether Watch Me Grow (WMG) can become a sustainable, inexpensive way to increase vegetable consumption in pre-schoolers while attending child care.

Who can participate?
Child care centers in North Carolina, which care for children between the ages of 3 – 5 years.

What does the study involve?
Child care centers were allocated to receiving the The Watch Me Grow (WMG) programme first, or receiving it at a later date. WMG is designed to encourage fruit and vegetable consumption among children in child care. Centers given the programme at a later date, received a garden and the curriculum materials, but not the regular technical assistance visits.

What are the possible benefits and risks of participating?
Centers will benefit from receipt of an on-site garden. Children enrolled at the center may benefit from increased consumption of fresh vegetables. To reduce the chance of harm, only non poisonous crops will be grown at the child care centers. There are no known risks of participating in the study.

Where is the study run from?
Duke University Medical Center, Durham, North Carolina, USA

When is the study starting and how long is it expected to run for?
The study began in March 2011 and is expected to run until November 2013.

Who is funding the study?

Child Nutrition


Centers allocated 1:1 to WMG intervention or delayed WMG intervention.

We compare the Watch Me Grow (WMG) garden-based intervention to a delayed intervention. WMG is a crop-a-month curriculum and garden intervention designed to encourage fruit and vegetable consumption among children in child care.
The intervention includes
1. Nutritional counseling to providers on low-cost ways to increase fruits and vegetables on the child care menu
2. Delivery of a multi-disciplinary pilot curriculum promoting fresh produce to providers and children and
3. Assistance establishing child care center gardens to get providers and children excited about growing their own fresh crops

Centers in the delayed intervention will receive a garden and the curriculum materials, but will not receive regular technical assistance visits.
