NEW ORLEANS (AP) A Children's Health Fund study finds dozens of infants and toddlers living in a Louisiana's trailer park for those displaced by Hurricane Katrina are anemic because of poor diets.

More than 40 percent of the 77 children under the age of four at Renaissance Village trailer park in Baker suffered from the condition. That's four times the national average.

Iron deficiency anemia can cause fatigue and learning problems.

Severe deficiency in young children can delay growth and development and even cause heart murmurs.

A 2007 Pediatric Nutrition Surveillance survey says Louisiana has one of the nation's highest anemia rates, with about 24 percent of all children below the age of 5 affected.
