Childcare Outdoor Learning Environments as Active Food Systems (COLEAFS)
Childcare Outdoor Learning Environments as Active Food Systems: Effectiveness of the Preventing Obesity by Design (POD) Gardening Component
調査の概要
詳細な説明
Objective: To assess the effectiveness of a gardening component on preschool children's knowledge, liking and consumption of fruit and vegetable consumption, and their level of physical activity during gardening season.
Intervention: Fruit and vegetable garden installation. Childcare centers were randomly assigned to one of three groups: Group 1, intervention (5 centers); Group 2, wait list control (5 centers); Group 3, no-intervention control (5 centers).
In Year 1 (Spring), baseline data was collected from Groups 1 and Group 2 (waitlist). Group 1, initial intervention centers, received the garden intervention in the Summer and both groups were assessed in the Fall, post intervention. No further data was collected from Group 1.
In Year 2 (Spring), Group 2 (waitlist, now intervention) and Group 3 were assessed. Group 2, received the garden intervention in the Summer of Year 2 and both groups were assessed in the Fall of Year 2.
No further data was collected.
Sample: 15 centers. Children: 286 (4 and 5 years old). Center demographic profile includes child data: age, gender, parental education, race/ethnicity, special needs, and height/weight (BMI). To avoid losing "graduating" five year old children, post-intervention data was gathered before school start date.

実験的:Group 1 - Intervention
Participating children have daily access to the fruit and vegetable garden beginning Year 1.
|
Garden installation: 6 raised planting beds (4x6x16") configured in a single line with direct sun at least 6 hrs./day, close to hose bib, sufficient distances to allow working from most sides, vegetable vines spill over space, and storage unit for tools. Planting beds constructed from a standard kit. Beds filled with high quality growing medium. Plants selection criteria: a) documented harvest success in NC Piedmont; b) able to be eaten raw, c) harvest times at the same time (except strawberries). Designated beds and plants: Bed 1: 4 pepper, 2 tomato; Bed 2: 20 bean on 2 mini-teepees, 2 cucumber (trellised); Bed 3: 1 yellow squash, 1 zucchini; Bed 4: 2 blueberry bushes, 12 strawberry; Bed 5: 2 cantaloupe. Bed 6: 2 watermelon. 2 Blackberries planted at ground level on trellis. |

Change in mean fruit knowledge 6-item, measured by pictorial questionnaire after 5 months of gardening.
時間枠:Change from baseline to 5 months
|
Measured by presenting child with an image of each of 6 fruit on a tablet screen and asking the child if he/she knows (Y/N) the fruit. Pictorial questionnaire based on Carraway-Stage, V., Spangler, H., Borges, M., & Goodell, L. S. (2014). Evaluation of a pictorial method to assess liking of familiar fruits and vegetables among preschool children. Appetite, 75, 11-20. Six fruits: apple, blueberries, blackberry, strawberry, cantaloupe, watermelon. Same fruits were planted in the garden except for apple that takes too long to produce fruit |

Change in fruit consumption, measured by mean weight of 6 snack-time fruit consumed after 5 months of gardening
時間枠:Change from baseline to 5 months
|
Objective measurement of grams of fruit consumed during snack time data collection. Store-bought, standard pieces of fruits offered on individual segmented trays (6" x 12"). Each tray is labeled with a child's ID number. Six fruits (approximately 50gr/each are served). The measure is based on the Fruit & Vegetable Snack Tool, Witt KE, Dunn C. Increasing Fruit and Vegetable Consumption among Preschoolers: Evaluation of Color Me Healthy. J Nutr Educ Behav. 2012;44(2):107-113. Fruit servings are weighed in grams before and after the snack consumption session to the nearest .01gr. Fruits offered for consumption are the same as shown on pictorial tablet questionnaires (knowledge and liking) and planted in the intervention gardens except for apple that takes too long to produce fruit. Six fruits: apple, blueberries, blackberry, strawberry, cantaloupe, watermelon. |

Change in physical activity level (percent of day at sedentary, moderate, and vigorous levels), measured by Actigraph GT3x+ after 5 months of gardening activities.
時間枠:Change from baseline to 5 months
|
Children wear Actigraph GT3x+ accelerometers for three consecutive days during same weeks of Outcome 1 - 6 data collection in April (before garden installation) and August (end of garden season) each study year. Minutes of sedentary (< 8.3 counts/5 sec), light (8.4-191 counts/5 sec), moderate (192-334 counts/5 sec), and vigorous (≥335 counts/5 sec) physical activity is computed based on METS. The measure is based on Evenson KR, Catellier DJ, Gill K, Ondrak KS, McMurray RG. Calibration of two objective measures of physical activity for children. J Sports Sci. 2008;26(14):1557-1565. doi:10.1080/02640410802334196 |
