Abstract

OBJECTIVES:

To determine population lipid profiles, awareness of hyperlipidaemia and adherence to Australian lipid management guidelines.

DESIGN AND SETTING:

Population survey in rural south-eastern Australia, 2004-2006.

PARTICIPANTS:

Stratified random sample from the electoral roll. Data from 1274 participants (40%) aged 25-74 years were analysed.

MAIN OUTCOME MEASURES:

Population mean total, low-density lipoprotein and high-density lipoprotein cholesterol (TC, LDL-C and HDL-C) and triglyceride (TG) concentrations, prevalence of dyslipidaemia, and treatment according to 2001 and 2005 Australian guideline target levels.

RESULTS:

Population-adjusted mean TC, TG, LDL-C and HDL-C concentrations were 5.38 mmol/L (95% CI, 5.30-5.45), 1.50 mmol/L (95% CI, 1.43-1.56), 3.23 mmol/L (95% CI, 3.16-3.30) and 1.46 mmol/L (95% CI, 1.44-1.49), respectively. Prevalence of hypercholesterolaemia (TC > 5.5 mmol/L or on treatment) was 48%. Lipid-lowering medication use was reported by 12%. Seventy-seven of 183 participants with established cardiovascular disease (CVD) or diabetes were untreated, and of the 106 treated, 59% reached the target LDL-C. Of those without CVD or diabetes already treated, 38% reached target LDL-C, and 397 participants at high absolute risk did not receive primary prevention. Ninety-five per cent of treated individuals with CVD or diabetes and 86% of others treated had cholesterol measured in the previous year. Sixty-nine per cent of individuals at low risk aged over 45 years had their cholesterol measured within the previous 5 years.

CONCLUSIONS:

A comprehensive national strategy for lowering mean population cholesterol is required, as is better implementation of absolute risk management guidelines - particularly in rural populations.
