Tummytime: Determining Optimal Dosage of Prone Positioning in Early Infancy
Study Details
Study Description
Brief Summary
The proposed study is a longitudinal, randomized control trial designed to determine the dosage of daily 'tummy time' needed in early infancy to influence ideal motor development and healthy body composition. Infants will be randomly assigned to one of three 'tummy time' groups: a group prescribed 0 to 30 minutes per day; a group prescribed 31 to 60 minutes per day; and, a group prescribed 61 or more minutes per day. Families will be encouraged to achieve the maximal minutes prescribed for their group and will keep a log of their daily tummy time. Participating infants will be assessed in their home for motor development and body composition at study entry and again every month for 12 months, at 15 months of age and at 18 months of age.

Detailed Description
Prone positioning or 'tummy time' in early infancy is advocated as important to support early motor development, improve overall strength, and prevent flattening of the back of the head. The American Academy of Pediatrics state that "a certain amount of prone positioning, or 'tummy time,' while the infant is awake and being observed is recommended to help prevent the development of flattening of the occiput and to facilitate development of the upper shoulder girdle necessary for timely attainment of certain motor milestones." However, specific recommendations on appropriate dosage of prone positioning are not available. In the absence of these specific recommendations, many infants may not be engaging in sufficient 'tummy time' for timely motor development. Moreover, insufficient 'tummy time' is linked to heightened obesity risk in early life. Given the increasing incidence of obesity in infants, primary preventative efforts need to begin early to reduce this risk.
The proposed study is a longitudinal, randomized control trial designed to determine the dosage of daily 'tummy time' needed in early infancy to influence ideal motor development and healthy body composition. Infants will be randomly assigned to one of three 'tummy time' groups: a group prescribed 0 to 30 minutes per day; a group prescribed 31 to 60 minutes per day; and, a group prescribed 61 or more minutes per day. Families will be encouraged to achieve the maximal minutes prescribed for their group and will keep a log of their daily tummy time. Participating infants will be assessed in their home for motor development and body composition at study entry and again every month for 12 months, at 15 months of age and at 18 months of age. Once a participant can independently transition in and out of the sitting position, the family will no longer be responsible for performing deliberate 'tummy time' activities or logging, but monthly motor development and body composition will continue to be monitored until the participant is 18 months of age.
