Objective: To evaluate a primary prevention care model using telephone support delivered through an existing health call centre to general practitioner-referred patients at risk of developing CVD, using objective measures of CVD risk reduction and weight loss. Design: Participants were randomised into two groups: (i) those receiving a telephone-supported comprehensive lifestyle intervention programme (CLIP: written structured diet and exercise advice, plus seven telephone sessions with the Heart Foundation Health Information Service); and (ii) those receiving usual care from their general practitioner (control: written general lifestyle advice). Fasting plasma lipids, blood pressure, weight, waist circumference and height were assessed on general practice premises by a practice nurse at Weeks 0 and 12. Conclusions:In general practice patients, delivering CLIP through an existing telephone health service is effective in achieving reductions in LDL-C and total cholesterol. While CLIP may have potential for wider implementation to support primary prevention of CVD, longer-term cost-effectiveness data are warranted. Keywords Telephone supportWeight loss Lipid reduction General practice CVD affects 3?5 million (17 %) Australians (1) and is a leading cause of death (34 % of all deaths in 2008) (2) . The major risk factors contributing to the burden of CVD in Australia include high blood pressure (42 %), high cholesterol (35 %), physical inactivity (24 %) (3) and overweight and obesity (21?3 %) (1) . It is estimated that 90 % of Australians have at least one modifiable risk factor for CVD (4) . This demonstrates the need for effective models of preventive health care that target elevated blood pressure, high cholesterol and weight to reduce CVD risk (5) .Growing evidence supports effective CVD risk reduction from dietary patterns that include plant sterols (6) , long-chain n-3 fatty acids (7) , fruits and vegetables (8) , nuts (9) and unsaturated oils (10,11) . A previous 6-week clinical-based intervention, conducted in sixty-five hypercholesterolaemic patients, showed that a structured lipid-lowering dietary pattern that utilised the synergistic effect of cardioprotective foods had significant positive health outcomes (12) . When compared with participants who received either (i) qualitative lifestyle advice alone or (ii) qualitative lifestyle advice together with 20 mg simvastatin/d, the intervention group exhibited significantly reduced LDL-cholesterol (LDL-C) by 15 % and reduced weight and waist circumference (12) . However, prior interventions have predominantly relied upon intensive face-to-face counselling, which is limited by financial cost, resource availability and reach.General practitioners offer an alternative delivery approach, as they are well placed to initiate successful

Objective: The CSIRO Total Wellbeing Diet (TWD) publication is an evidencebased weight management strategy utilising a structured higher protein diet as part of a nutritionally balanced lifestyle programme. Despite its popularity, the impact of TWD on weight status, weight loss and food choices of Australians was unknown. Design: An independent representative survey was conducted in 2006. Sociodemographic differences in awareness, use of TWD and the impact on weight status and well-being were investigated via computer-aided telephone interviews and web-based surveys. Setting: Australia. Subjects: A total of 5026 men and women aged 18-60 years. Results: Consumers were highly aware of TWD (66 %) with personal use reported by 7?5 % of the total sample (n 5026). An additional 2?5 % (126 people) were members of a household that used TWD. In all, 80 % of TWD purchasers actively used the eating plan with approximately 3?8 % losing an average self-reported weight loss of 5?7 kg (SD 5 1?72 kg; range 5 1-13 kg). Results showed that awareness was greatest among women (73?79 % v. 58?27 %), those over 50 years of age (69?39 % v. 62?88 %) with no children in the household (69?00 % v. 64?88 %), tertiary educated people (72?58 % v. 63?22 %) and those with more previous weight loss attempts (79?66 % v. 70?24 %). Logistic regression was unable to predict an identifiable sociodemographic profile of TWD users.Conclusions: The present study shows widespread uptake of TWD in Australia with few sociodemographic differences. Self-reported increased awareness of nutrition and well-being as well as weight loss indicates that TWD has been a successful delivery mechanism for lifestyle advice.
