Ruth Waldman Camacho, 68, a former pediatrician who helped officials in developing countries establish and evaluate health care centers and medical treatment delivery systems, died of cancer Aug. 16 at her home in Bethesda.

For about four years after she came to Washington in 1964, Dr. Camacho worked for the Pan American Health Organization as chief of the health department and population dynamics. In the early 1970s, she began working as an independent consultant evaluating public health centers and networks in Latin America, Southeast Asia and Africa.

She was the author of more than 20 articles on international health, teenage pregnancy, family planning, minority health, folk medicine and nutrition. In the 1980s, she served as an adviser to the Presidential Committee on Careers for Women.

Earlier in her career, she specialized in pediatrics, adolescent medicine and tropical diseases in Paris, New York City and Havana. She worked as medical director of Operation Head Start in Harlem and the Bronx, and she was a founder and director of the adolescent health maintenance center at St. Luke's Hospital in New York City.

A native of New York, she graduated from Brooklyn College and received a medical degree from the University of Lausanne in Switzerland.

Survivors include her husband, Jose E. Camacho of Bethesda; two children, Elena Byrd of Nashville and Alex Camacho of New York City; and six grandchildren.
