AbstractA cardiovascular disease screening and education campaign was conducted throughout the North Coast Region of New South Wales from 1987 to 1991. Objectives were: to screen 20 per cent of the adult population for blood cholesterol and other heart disease risk factors; to raise awareness of the risks associated with a high-fat diet; to provide nutrition counselling and referral advice for those with elevated cholesterol; and to monitor these participants' cholesterol levels with a follow-up test at three months. During the five years, 42,869 individuals or 18 per cent of North Coast adults participated, with some overrepresentation of women aged 40 to 60 years. Initially, 65 per cent of participants had elevated cholesterol levels (> or = 5.5 mmol/L) and 46 per cent were overweight (body mass index over 25). A three-month retest was offered to all participants with elevated cholesterol, of whom 53 per cent attended. Participants who received nutrition counselling generally reported dietary changes which were reflected in significant cholesterol and weight reductions. Of participants who attended retest, 63 to 87 per cent had reduced cholesterol levels and 57 to 71 per cent reduced weight. A stratified random sample of participants was retested at one and three years. Reductions in cholesterol were well maintained for one year but showed signs of relapse after three years. There was a tendency for initially lower cholesterol levels to increase over a three-year period. Contributing factors included aging, regression to the mean and complacency. Maintenance may be enhanced by regular reinforcement of nutrition changes and development of more supportive environments.
