NUTRITION, HEALTH, AND HUMAN CAPITAL DEVELOPMENT: EVIDENCE FROM SOUTH KOREA, 1946-1977
ABSTRACT
Using newly collected archival data, this study investigated how nutritional availability in two crucial periods for human growth, namely, early childhood and adolescence, affected the heights of South Korean conscripts born from 1946–1957. Results strongly suggest nutrition was an important determining factor of biological standards of living indicated by adult height. Provisions of calories and protein were associated strongly with larger stature. Food availability during early childhood was more critical for human growth than nutrition in adolescence. Nutrition in growing ages also had a strong effect on educational attainment. Increased nutritional supply in adolescence mitigated the negative consequences of early-life exposure to the Korean War. Improved nutrition in early childhood and adolescence accounted for 30% to 50% of the increase in adult height (about 2 cm) that was gained between the 1951 and 1957 birth cohorts. Increased nutritional availability during early childhood explains the majority of the contribution.
