P. Glewwe et Em. King, The impact of early childhood nutritional status on cognitive development:Does the timing of malnutrition matter?, WORLD BAN E, 15(1), 2001, pp. 81-113
This article uses longitudinal data from the Philippines to examine whether
the timing of malnutrition in early childhood is a critical factor in dete
rmining subsequent cognitive development. Although some observers have argu
ed that the first six months of life are the most critical in the sense tha
t malnutrition during that time period harms cognitive development more tha
n malnutrition later in life, analysis of the Philippines data does not sup
port this claim. To the contrary, the data suggest that malnutrition in the
second year of life may have a larger negative impact than malnutrition in
the first year of life.
