简要总结
The purpose of this study is to evaluate the effect of a 7-month social marketing program - Healthy Me, Healthy We (previously called Our Year of Healthy Living) - in improving preschool children's (3-4 years) diet and physical activity behavior. Healthy Me, Healthy We will use social marketing approaches in the child care center to promote the use of healthy diet and physical activity behaviors by children, as well as their teachers and parents. The program will use visual cues, educational materials, activities, and a song to deliver targeted healthy behavior messages that connect the teacher, child, and parents. Centers will implement the Our Year of Healthy Living program in their classrooms over the course of a school year (October-April). Prior to initiation and after completion of the program, researchers will collect information about diet, physical activity, child body mass index (BMI), and center and home environment information from participants. From the beginning of the program to the end, children enrolled in the program will have 1) a greater increase in physical activity and decrease in sedentary time, 2) improved diet, and 3) smaller increase in body mass index compared to children in centers that do not complete the program. Additionally, from the beginning of the program to the end, homes and centers that participate in the program will have greater improvements in scores on the home and center environment assessments compared to centers and homes that do not participate.
详细描述
The purpose of this study is to evaluate the effect of the 7-month social marketing intervention - Healthy Me, Healthy We (previously called Our Year of Healthy Living) - in improving preschool children's (3-4 years) diet and physical activity behaviors. The study will use a two-arm, cluster randomized controlled design and a sample of 90 child care centers and 810 children (9 parent-child dyads/center).
For this study, the investigators will recruit 90 child care centers from a mix of urban/suburban and rural areas. Potential child care centers in these counties will be identified using an online database of licensed child care facilities maintained by the North Carolina (NC) Division of Child Development and Early Education. State and local community partners will be engaged to help inform centers in targeted counties about the study. Direct recruitment of centers will employ a variety of strategies (e.g., mail, email, telephone, in-person contacts). Once a center expresses interest, the investigators will work with the center director to recruit nine parent-child dyads and five teachers from the 3- and 4-year old classrooms.
Outcome Measures:
A series of measurements will be collected on participating children, parents, and child care providers at two time points - baseline and follow-up. Primary outcomes measures will assess child physical activity and diet quality. Secondary outcomes measures will assess child weight, center and home environment. These measures will be collected in large part during two-day on-site visits to the child care center, and supplemented with self-administered surveys. Center visits will be conducted by data collectors who have undergone extensive training and certification on all measurement procedures and are blinded to study-arm assignment. Identical data collection protocols will be used at baseline and follow-up.
Children's physical activity will be measured using accelerometers. A data collector will fit each participating child with an accelerometer on a belt during the morning of the first day of the center visit. The child will wear the accelerometer for seven full days - both at child care and at home. Once data are downloaded, age-appropriate cut-points will be applied in order to calculate daily minutes of non-sedentary physical activity.

研究组 & 干预措施
Intervention group
Centers in this group will participate in the Healthy Me, Healthy We program.

结局指标
主要结局
Change in child physical activity
时间窗: Measures collected 3-10 weeks prior to start of intervention and 1-8 weeks post intervention
Physical activity of 3-4 year old children will be assessed via accelerometry using ActiGraph monitors worn over the right hip for 7 days. Age-appropriate cut-points will be applied to calculate minutes of non-sedentary activity.
Change in child diet quality
时间窗: Measures collected 3-10 weeks prior to start of intervention and 1-8 weeks post intervention
Dietary intakes of 3-4 year old children will be assessed via direct observation of foods eaten at child care and parent report of foods eaten outside of child care. These dietary intake data will be used to calculate Healthy Eating Index scores as an indication of diet quality.
次要结局
- Change in child weight(Measures collected 3-10 weeks prior to start of intervention and 1-8 weeks post intervention)
- Change in nutrition and physical activity environments in homes and child care centers(Measures collected 3-10 weeks prior to start of intervention and 1-8 weeks post intervention)
