Prevention of Overweight in Infancy
This trial is active, not recruiting.
|Conditions||obesity, growth, sleep|
|Sponsor||University of Otago|
|Start date||May 2009|

Obesity is one of the biggest threats to health in the 21st century. Rapid weight gain in the first year of life tends to lead to overweight in children, which in turn leads to overweight in adults. This rapid early weight gain occurs most often at weaning when eating patterns emerge. Infant sleep problems also appear to be associated with the risk of becoming overweight, and contribute to maternal post-natal depression. We propose to undertake a 4-arm randomised controlled trial to determine whether extra education and support for families around weaning and development of early food and activity habits, with or without intervention to improve infant sleep, will decrease the current risk patterns of rapid excessive early childhood weight gain in New Zealand. This would provide strong evidence for the value of such a strategy in the long term control of the obesity epidemic and its consequent complications.

|Official title||Primary Prevention of Rapid Weight Gain in Early Childhood: a Randomised Controlled Trial|
|Principal investigator||Barry J Taylor, FRACP|
|Description||We plan on undertaking a 4-arm randomised controlled trial to test the following hypotheses: 1. That anticipatory guidance and extra education and support in infancy around weaning and decreasing/avoiding TV watching will delay the timing of introduction of solid foods, will be associated with more successful introduction of nutrient dense foods with appropriate portion size and decrease small screen exposure leading to a lower number of children with excessive weight velocity in infancy and early childhood. 2. That anticipatory guidance, education and extra support around the early development of infant sleeping patterns will decrease sleep problems, increase infant sleeping time, decrease arousals at night and lower sleep latency which will in turn influence rate of early infant weight gain. 3. That interventions 1 and 2 will interact additively with regard to infant and early childhood weight gain. 4. That intervention 2 will lead to lower rates of maternal depression and increased family well being.|
