Abstract OBJECTIVE: To assess the effectiveness of a dietitian-based nutrition counseling and education program for patients with hyperlipidemia. DESIGN: A 4-session program implemented as a complement to a randomized physician-delivered intervention. SUBJECTS/SETTING: From 12 practice sites of the Fallon Clinic, 1,162 subjects with hyperlipidemia were recruited, 645 of whom had data sufficient for our primary analyses. INTERVENTION: Two individual and 2 group sessions conducted over 6 weeks. MAIN OUTCOME MEASURES: Total and saturated fat levels; serum low-density lipoprotein cholesterol levels; and body weight, measured at baseline and after 1 year. STATISTICAL ANALYSES: Multiple linear regression was used to evaluate changes in outcome measures. RESULTS: After 1 year, there were significant reductions in outcome measures for subjects attending 3 or 4 nutrition sessions vs subjects attending fewer than 3 sessions or those never referred to a nutrition session. Reductions (mean +/- standard error) in saturated fat (measured as percent of energy) were 2.7 +/- 0.5\%, 2.1 +/- 0.5\%, and 0.3 +/- 0.1\%, respectively. These reductions correspond to roughly a 22\% relative change from baseline in those attending 3 or 4 sessions. Corollary reductions were observed for total fat (measured as percent of energy): 8.2 +/- 1.4\%, 5.0 +/- 1.4\%, and 0.7 +/- 0.4\%; low-density lipoprotein cholesterol: 0.48 +/- 0.11 mmol/L, 0.13 +/- 0.11 mmol/L, and 0.02 +/- 0.03 mmol/L; and body weight: 4.5 +/- 0.9 kg, 2.1 +/- 0.8 kg, and 1.1 +/- 0.2 kg. The specified changes were additive to those of the physician-delivered intervention. APPLICATIONS/CONCLUSIONS: This investigation provides empirical data demonstrating the effectiveness of a dietitian-delivered intervention in the care of patients with hyperlipidemia.
