Jane Elizabeth (Betsy) Kenworthy, 63, a health education writer and editor for 20 years, died Thursday of cancer at Johns Hopkins University Hospital in Baltimore.

Mrs. Kenworthy, wife of retired News York Times correspondent E. W. Kenworthy, was a resident of Northwest who had worked since 1957 as a writer and editor with Health and Education Resources, Inc., of Bethesda, which prepares training materials for hospital technicians.

A native of New Haven, Conn., Mrs. Kenworthy was the daughter of Henry Holland Carter, for many years head of the English department at Indiana University.

She was a 1934 graduate of Oberlin College, where she earned a degree in English. She taught English at Indiana University and the University of Illinois before coming here in 1943 with her husband, an environmental affairs reporter at the Times who retired last year.

From 1943 to 1946, Mrs. Kenworthy worked with former U.S. Ambassador Katie Louchheim in the information office of the old United Nations Relief and Rehabilitation Agency headed by former New York Gov. Herbert H. Lehman.

She lived with her husband in Baltimore, London and New York before returning to Washington in 1957, when she began working with the Bethesda firm.

At her death, Mrs. Kenworthy was preparing a series of audiovisual lectures for microbiologists. In the 1960s, she edited studies at Johns Hopkins and worked as an editor with the old Center for International Economic Growth here, a group concerned with furthering foreign economic aid.

In addition to her husband, of the home, she is survived by two sons, John, of Washington, and Thomas, of Amherst, N.H.; a daughter, Mrs. Richard Arenberg, of Alexandria, and three sisters, Mrs. J.W. Schaefer of Watchung, N.J., Margaret Tenney of Boston, and Bertha Anne Carter, of Madison, Ind.

The family suggests that memorial contributions be sent to the Johns Hopkins University Gynecological Oncology Fund at the university in Baltimore.
