In this blog Paul Dornan of Young Lives and Frances Mason of Save the Children  describe some of their discussions around nutrition during adolescence. Save the Children is keen to explore all the options to help tackle malnutrition, and have recognised adolescence as a neglected group while Young Lives researchers have explored the extent and implications of post infancy recovery. Now with a longer age span of data, researchers are using the Young Lives study to examine the potential of adolescence as a further ‘critical window’.
