Cholesterol-related counseling by registered dietitians in northern California.

BACKGROUND: An estimated 40 million Americans have serum cholesterol levels that warrant medically supervised dietary intervention. Although registered dietitians are expected to play an important role in treating these patients, current treatment practices in the community are largely unknown. METHODS: A questionnaire concerning treatment practices was mailed to all 377 registered dietitians listed in the directories of the American Dietetic Association for two large California districts. Number of patients seen and length and content of dietary counseling were ascertained for three types of patients: (a) hypercholesterolemic outpatients without heart disease, (b) hypercholesterolemic outpatients who have heart disease, and (c) inpatients with myocardial infarction. RESULTS: A return rate of 59% (n = 252) was obtained for the questionnaire. A total of 44% of the registered dietitians counseled hypercholesterolemic patients in any of the categories surveyed. About 30% of the respondents counseled hypercholesterolemic outpatients without heart disease. They saw an average of 4.9 such patients a week, spent an average of 53 min in an initial session, and usually did not see the patient again in follow-up. Fewer than 10% of patients had as many as four sessions. About 27% of the respondents saw hypercholesterolemic outpatients with heart disease, averaging 3.5 such contacts per week. The reported practices were similar to those provided to noncardiac outpatients. About 22% of registered dietitians worked with hospitalized myocardial infarction patients. They spent an average of a total of 41 min over 2.5 visits with each patient. CONCLUSION: Currently, outpatient registered dietitian counseling for hypercholesterolemia appears to be limited in both the number of patients reached and the duration of the counseling. Further research into the impact of, barriers to, and efficacy of alternative delivery methods of dietary counseling is needed.

Strategies for increasing early adherence to and long-term maintenance of home-based exercise training in healthy middle-aged men and women.

Two studies were undertaken to compare strategies for the adoption and maintenance of moderate-intensity, home-based exercise training. In the study of adoption, 52 men and women who had served for 6 months as controls for a study of moderate-intensity, home-based exercise training received 30 minutes of baseline instruction. They were then randomized to receive continuing instruction and support through 10 staff-initiated telephone contacts of 5 minutes each every 2 weeks, or to receive no telephone contacts. In subjects receiving telephone contacts, peak oxygen uptake increased significantly after 6 months, whereas no increase was observed in subjects receiving no staff support (p less than 0.05). In the maintenance study, 51 men and women who had significantly increased their peak oxygen uptake by 6 months of moderate-intensity, home-based exercise training were randomized to undergo daily self-monitoring and receive adherence instructions, or undergo weekly self-monitoring only, during a second 6-month period of training. Subjects performing daily self-monitoring reported completing significantly more exercise training sessions during the 6 months of training than subjects performing weekly self-monitoring; functional capacity in both groups remained higher than before training (p less than 0.05). Taken together, these studies suggest that brief baseline instruction followed by continuing telephone contact with staff can be used to help people adopt a moderate-intensity, home-based exercise training program that can be maintained by simple self-monitoring strategies.

Smoking cessation after acute myocardial infarction: the effects of exercise training.

To determine the influence of exercise training on smoking after acute myocardial infarction (AMI), smoking rates in 42 pre-AMI smokers assigned to exercise training were compared with 26 pre-AMI smokers assigned to no training. Exercise training occurred 3-26 weeks after AMI. The increase in functional capacity in 3-26 weeks was significantly greater in training than in no-training patients: 1.8 vs. 1.2 METs respectively (p less than 0.05). Adherence to exercise training was higher in non-smokers and former smokers than in those who continued to smoke: 89% and 88% vs. 80% respectively (NS). The prevalence of smoking 6 months post-AMI was lower in training than in no-training patients: 31% vs. 39% respectively (NS). Plasma thiocyanates collected on a random sample of 42 patients suggested that 19% of patients who are smoking after MI fail to report doing so. Self-reported cigarette consumption at 28 weeks was half as great in training as in no-training patients: 11 +/- 7 vs. 22 +/- 16 cigarettes per day (p less than 0.03). Firm advice to stop smoking followed by medically supervised exercise training with frequent followup reduces self-reported cigarette consumption in patients after AMI.
