Serum lipid concentrations in the Koki community: a preliminary report

Serum cholesterol and triglyceride concentrations were estimated in a self-selected sample of 9% of the adults over the age of 18 years in the urban community of Koki in Port Moresby, in which there is a high prevalence of diabetes. There were 84 males and 58 females in the sample. The mean age was 32.6 years, with the males significantly older than the females. Mean cholesterol and triglyceride levels were 4.7 mmol/l and 1.2 mmol/l respectively, and significant sex differences were observed, with males demonstrating higher levels, even in the younger age group. A high prevalence of obesity was observed in both males (40%) and females (55%). The prevalence of hyperlipidaemia was higher in males than females and was also more frequently observed in obese than non-obese subjects of either sex. A significant number (25%) of young subjects (18-30 years) exhibited serum lipid concentrations in excess of recommended levels. Our results suggest that, in contrast to previous reports, elevated serum cholesterol and triglyceride levels are present in this community, and may represent an increased risk for the development of ischaemic heart disease.
