Title of project: 
Does high protein intake in infancy associate with rapid growth beyond infancy?
Proposal summary: 

We aim to investigate protein intakes and dietary sources of protein at 8 months of age and relate these to growth trajectories up to 10 years. In addition we will assess the tracking of protein throughout childhood

Research questions: We will use the diet diary data collected in ALSPAC at 8 months (n greater than 1100) to calculate protein intake and assign infants to quintiles of protein intake. Within these quintiles we will evaluate:

1 What are the sources of protein in the diets of eight-month-olds?

2 Does high protein intake track though childhood?

3 Is high protein intake within the context of the whole diet associated with more rapid growth during infancy?

4 Is there any difference in rates of growth between quintiles of protein intake into later childhood?

Outcome measures: Weight, height and BMI through out infancy and childhood.
