Arms Assigned Interventions
Experimental: Gardening Program Other: Garden Fit
8-week summer gardening program. 9am-12pm on Monday, Wednesday, Friday and 9am-12:30pm on Tuesday and Thursday. Activities included gardening (preparing soil for planting, planting seeds and seedlings, mulching, weeding, watering, and harvesting), preparing meals with fresh foods from the garden, and other garden activities and games.
Other Name: Garden Fit 2009
No Intervention: Control
Subjects received the standard of care for the summer.

Detailed Description:
In the past two decades, the combination of unhealthy eating and physical inactivity has contributed to doubling the percentage of children and adolescents who are overweight. Childhood overweight is known to lead to increased risk for several morbidities in childhood and into adulthood including type 2 diabetes mellitus, hypertension, and cardiovascular disease. Recent data shows that children experience greater and more variable increases in BMI during summer vacation than during the school year. Our project aims to determine whether summer weight gain is due to a decrease in physical activity or an increase in daily calories as well as to assess the effectiveness of a summer gardening program on preventing summer body fat gain. We will randomize 40 middle-school children who are above the 95th percentile for BMI into either a control or intervention group. The control group will receive the standard of care and the intervention group will participate in Garden Fit, a summer gardening project at Troy Gardens in Madison, WI. As part of Garden Fit, subjects will participate in weeding, landscaping and trail maintenance activities as well as preparing meals twice a week with fresh foods from the gardens. We hypothesize that summer weight gain is due to a worsening of healthy lifestyle (decreased physical activity from school to summer and increased eating of high calorie snacks). Additionally, we hypothesize that an intervention that increases physical activity and provides increased access to healthy foods will reduce the trend of summer BMI increase.
