Summary Measurements of total serum cholesterol were made in Australians and in natives living in the Central Highlands of New Guinea (Wabag and Chimbu) and on the coast. Dietary fat provides 0% to 5% of the caloric intake in natives and 35% to 40% in Australians. The total cholesterol level in natives was lower than that of Australians. Males, 20 to 40 years of age, had 223 milligrammes of cholesterol per 100 millilitres of serum in Australia, 144 in Wabag, 130 in Chimbu, and 124 on the coast. Unlike Australians, the natives showed no upward trend in cholesterol level with age, and the value was lower in males (in Wabag) than in females. Paper electrophoresis of serum from males 20 to 40 years of age showed that the beta lipoproteins accounted for 78% of the total cholesterol in Australians, 80% in Chimbus and 86% in coastal natives. The percentage tended to increase with the total cholesterol level in Australians but to remain constant, regardless of total level, in the natives. A group of employed natives who had been eating extra food (18% of calories from fat) for one to two years had the same average total serum cholesterol concentration and lipoprotein distribution as the ordinary village natives.
