Dr. Jack P. S'"ons, professor at Louisiana State university school of medicine'; New Orleans, says every American of three years old probably has the beginnings of hardening of the arteries.
Autopsies nave shown the fatty streaks marking the first stage of the disease begin to form on aortas of some children even before the age of three, Dr. Strong told the final session of the Co-operative Arteriosclerosis Research Group here yesterday.
...Two doctors reported finding that hardening of the arteries occurs at different times among races.
They are Dr. Carlos Tejada of the nutritions institute of Central America and Panama and Dc Marion Guidry of the Louisiana State university medical school.
Dr. Tejada. studied hardening of the arteries in Mayan Indians and Costa Ricans. Dr. Guidry studied New Orleans white persons and New Orleans Negroes.
They found:
1. New Orleans Negroes have a higher incidence of the disease's first stage —- fatty streaks—between the ages of XI and 15 than do New Orleans whites, Mayans or Costa Ricans.
2. New Orleans whites have a higher incidence of the disease's second stage—fibrous patches—between the ages of 30 and 40 than do New Orleans Negroes, Mayans or Costa Ricans.
Dr. Tejada and Dr. Guidry said their findings gave support to the theory that diet alone is not the cause of hardening of the arteries,
