Progress in expanding breast-feeding and fighting measles and malaria has improved the health of children worldwide, but many in developing nations still don't have enough to eat, UNICEF said on yesterday.

The United Nations Children's Fund released a report on global child health, citing some strides while pointing to persistent problems in sub-Saharan Africa and elsewhere.

"We're seeing some significant progress in a number of areas in different parts of the world," Alan Court, UNICEF chief of programs, told reporters. "There's a lot more to do."
