to Support Fetal Growth Give Birth to Low Birth
Weight Infants (These babies experience high
mortality) Undernourished Children are Sicker
and Develop More Slowly Grow into Adults whose
Mental/Physical Capacities may have
suffered Contribute Low Productivity to the
workforce

Measuring Nutritional Status in Populations 1.
Infant Mortality Rate (deaths/ 1000 births) 2.
Number of Low Birth Weight Babies (LBW
Babies/ 1000 live births)

Causes of Food Shortage
FAMINE NATURAL DISASTERS WAR DROUGHT OVERPO
PULATION POOR LAND USE, EROSION
