Abstract

OBJECTIVE: To compare the efficacy of brief dietary intervention by family physicians in their daily practice and in group sessions to standard dietetic treatment in mild to moderate hypercholesterolemia. DESIGN: Randomised clinical trial. SETTING: Family practice clinic in a remote community. PARTICIPANTS: Between September 1, 1991 and September 30, 1992, 135 men and women between 20 and 60 years old with mild to moderate hypercholesterolemia were recruited and randomly assigned to three treatment groups to be taught the American Heart Association low fat diet. Each participant had an LDL-C reading higher than the desirable level set by the Canadian Consensus Conference on Cholesterol. INTERVENTIONS: The three treatment groups received different interventions: individual consultations with a family physician in his office (phase I); group sessions with a physician and a dietician (phase II); and individual consultations with a dietician (phase II). Participants were followed for 6 months with visits and blood tests every 2 months. MAIN OUTCOME MEASURES: Reduction in serum levels of total cholesterol, LDL-C, HDL-C, and triglycerides was measured after 2, 4, and 6 months of dietary treatment. Changes in risk factors (smoking, weight, level of physical activity) and patients' cholesterol/saturated fat index were also measured. RESULTS: Ninety-nine subjects completed the 6-month regimen. The mean reduction in serum LDL-C was 0.08 mmol/L (1.8%) in Group I, 0.07 mmol/L (1.6%) in Group II, and 0.28 mmol/L (6.3%) in Group III (P = 0.94). An LDL-C reduction of 10% or more relative to initial level was observed in 27% of participants in Group I and approximately 40% of subjects in the other two groups (P = 0.41). Counseling resulted in a decrease in body weight, smoking, and dietary fat consumption and an increase in physical activity. CONCLUSIONS: Treatment by a dietician achieved better results and should remain the standard. Physicians should focus on the detection and control of other heart disease risk factors.
