OBJECTIVES: the study aimed to determine age and gender specific levels of lipids and lipoproteins in New Zealanders. Participants were randomly selected from 20 general electoral roles, and from a sample of 15-18 year olds. METHODS: plasma cholesterol, LDL cholesterol, HDL cholesterol and triglyceride levels were measured in 2941 men and women aged 15-99 years. RESULTS: mean (SD) plasma cholesterol was 6.0 (1.3) mmol/L in men and 6.1 (1.3) mmol/L in women. There was a marked variation in total cholesterol and calculated LDL cholesterol with age, and the pattern was different in men and women. There was also a considerable regional variation; levels tending to increase from north to south. Overall mean cholesterol levels adjusted for age and geographical distribution were 5.8 and 6.0 mmol/L for men and women respectively. CONCLUSION: the fact that approximately a third of the adult population in New Zealand under 65 years have cholesterol levels greater than 6.5 mmol/L indicates the need for effective diet and lifestyle changes to reduce the high rates of CHD.
