We aim to investigate the effects of lifestyle change on early childhood growth among the Daasanach, a population of semi-nomadic pastoralists living in remote northern Kenya. We further seek to understand the tradeoffs between growth and other competing energy demands (i.e. physical activity and immune function) in a population transitioning towards a more sedentary and market integrated way of life.
