Predictors of adherence in the Women's Health Initiative Calcium and Vitamin D Trial.

The authors analyzed data from the Women's Health Initiative (WHI) Calcium and Vitamin D Supplementation Trial (CaD) to learn more about factors affecting adherence to clinical trial study pills (both active and placebo). Most participants (36,282 postmenopausal women aged 50-79 years) enrolled in CaD 1 year after joining either a hormone trial or the dietary modification trial of WHI. The WHI researchers measured adherence to study pills by weighing the amount of remaining pills at an annual study visit; adherence was primarily defined as taking > or = 80% of the pills. The authors in this study examined a number of behavioral, demographic, procedural, and treatment variables for association with study pill adherence. They found that relatively simple procedures (ie, phone contact early in the study [4 weeks post randomization] and direct social contact) later in the trial may improve adherence. Also, at baseline, past pill-use experiences, personal supplement use, and relevant symptoms may be predictive of adherence in a supplement trial.

Racial Differences in Misclassification of Healthy Eating Based on Food Frequency Questionnaire and 24-Hour Dietary Recalls.

OBJECTIVES: To examine the agreement in nutrient intake and alternate healthy eating indices (AHEI) between a self-administered Food Frequency Questionnaire (FFQ) and 24-hour recall (24HR) measurements of diet by race, among urban older women. DESIGN: Cross-sectional observational study. SETTING: Urban neighborhoods in Washington, DC, USA. PARTICIPANTS: Community-dwelling White and Black women aged 65 and older. MEASUREMENTS: In 2014 and 2015, 49 White and 44 Black older women were queried on diet using both FFQ and 24-hour recalls. The correlation coefficients of 55 nutrient intake measures and agreements on healthy eating classification between the two instruments were compared overall and by race. RESULTS: The mean correlation coefficient (rho) was 0.46 for Whites and 0.23 for Blacks. For 47 measures, rho was lower for Blacks. Whites had a strong correlation of ≥0.5 for 28 items, while Blacks had strong correlations for only 3 items. Based on FFQ, the mean (SD) of AHEI were 54.0 (10.3) for Whites and 45.9 (8.8) for Blacks (p<0.001). Based on 24HR, the mean (SD) were 43.9 (10.8) for Whites and 33.2 (9.6) for Blacks (p<0.001). Using 32 as the cutoff (40% of maximum AHEI score), 50% of Blacks and 14% of Whites were classified as eating unhealthy based on the 24HR, versus 2.6% and 0% based on the FFQ. CONCLUSION: The FFQ has limited ability to accurately assess nutrient intake among older Black women, and tends to underestimate racial differences in healthy eating. The FFQ should be further improved for use in racial disparities research of healthy eating in older age, using a larger sample of older women with racial and geographic diversities.

Gender and Age Differences in Levels, Types and Locations of Physical Activity among Older Adults Living in Car-Dependent Neighborhoods.

BACKGROUND: A thorough understanding of gender differences in physical activity is critical to effective promotion of active living in older adults. OBJECTIVES: To examine gender and age differences in levels, types and locations of physical activity. DESIGN: Cross-sectional observation. SETTING: Car-dependent urban and rural neighborhoods in Worcester County, Massachusetts, USA. PARTICIPANTS: 111 men and 103 women aged 65 years and older. MEASUREMENTS: From 2012 to 2014, participants were queried on type, frequency and location of physical activity. Participants wore an accelerometer for 7 consecutive days. RESULTS: Compared to women, men had a higher mean daily step count (mean (SD) 4385 (2122) men vs. 3671(1723) women, p=0.008). Men reported higher frequencies of any physical activity and moderate-to-vigorous physical activity, and a lower frequency of physical activity inside the home. Mean daily step counts and frequency of physical activity outside the home decreased progressively with age for both men and women. Women had a sharper decline in frequencies of self-reported physical activity. Men had a significant decrease in utilitarian walking, which women did not (p=0.07). Among participants who reported participation in any physical activity (n=190), more women indicated exercising indoors more often (59% vs. 44%, p=0.04). The three most commonly cited locations for physical activity away from home for both genders were streets or sidewalks, shopping malls, and membership-only facilities (e.g., YMCA or YWCA). The most common types of physical activity, performed at least once in a typical month, with over 40% of both genders reporting, included light housework, brisk walking, leisurely walking, and stretching. CONCLUSION: Levels, types and location preferences of physical activity differed substantially by gender. Levels of physical activity decreased progressively with age, with greater decline among women. Consideration of these gender differences is necessary to improve the effectiveness of active living promotion programs among older adults.

Longitudinal changes in the dietary inflammatory index: an assessment of the inflammatory potential of diet over time in postmenopausal women.

BACKGROUND/OBJECTIVES: The dietary inflammatory index (DII) measured at one time point is associated with risk of several chronic diseases, but disease risk may change with longitudinal changes in DII scores. Data are lacking regarding changes in DII scores over time; therefore, we assessed changes in the DII in the Women's Health Initiative (WHI). SUBJECTS/METHODS: DII scores were calculated using data from repeated food frequency questionnaires in the WHI Observational Study (OS; n=76 671) at baseline and year 3, and the WHI Dietary Modification trial (DM; n=48482) at three time points. Lower DII scores represent more anti-inflammatory diets. We used generalized estimating equations to compare mean changes in DII over time, adjusting for multiple comparisons, and multivariable-adjusted linear regression analyses to determine predictors of DII change. RESULTS: In the OS, mean DII decreased modestly from -1.14 at baseline to -1.50 at year 3. In the DM, DII was -1.32 in year 1, -1.60 in year 3 and -1.48 in year 6 in the intervention arm and was -0.65 in year 1, -0.94 in year 3 and -0.96 in year 6 in the control arm. These changes were modified by body mass index, education and race/ethnicity. A prediction model explained 22% of the variance in the change in DII scores in the OS. CONCLUSIONS: In this prospective investigation of postmenopausal women, reported dietary inflammatory potential decreased modestly over time. Largest reductions were observed in normal-weight, highly educated women. Future research is warranted to examine whether reductions in DII are associated with decreased chronic disease risk.

Provider training for patient-centered alcohol counseling in a primary care setting.

OBJECTIVE: To assess the impact of a brief training program on primary care providers' skills, attitudes, and knowledge regarding high-risk and problem drinking. DESIGN: Training plus pretesting and posttesting for program efficacy. SETTING: Ambulatory primary care clinic; academic medical center. PARTICIPANTS: Fourteen attending physicians, 12 residents, and 5 nurse practitioners were randomized by clinical team affiliation to a Special Intervention or usual care condition of a larger study. We report the results of the training program for the Special Intervention providers. INTERVENTION: Providers received a 2-hour group training session plus a 10- to 20-minute individual tutorial session 2 to 6 weeks after the group session. The training focused on teaching providers how to perform patient-centered counseling for high-risk and problem drinkers. MAIN OUTCOME MEASURES: Alcohol counseling skills; attitudes regarding preparedness to intervene and perceived importance and usefulness of intervening with high-risk and problem drinkers; and knowledge of the nature, prevalence, and appropriate treatment of alcohol abuse in primary care populations. RESULTS: After training, providers scored significantly higher on measures of counseling skills, preparedness to intervene, perceived usefulness and importance of intervening, and knowledge. CONCLUSION: A group training program plus brief individual feedback can significantly improve primary care providers' counseling skills, attitudes, and knowledge regarding high-risk and problem drinkers.

Brief physician- and nurse practitioner-delivered counseling for high-risk drinkers: does it work?

BACKGROUND: There is a need for primary care providers to have brief effective methods to intervene with high-risk drinkers during a regular outpatient visit. OBJECTIVE: To determine whether brief physician- and nurse practitioner-delivered counseling intervention is efficacious as part of routine primary care in reducing alcohol consumption by high-risk drinkers. METHODS: Academic medical center-affiliated primary care practice sites were randomized to special intervention or to usual care. From a screened population of 9772 patients seeking routine medical care with their primary care providers, 530 high-risk drinkers were entered into the study. Special intervention included training providers in a brief (5- to 10-minute) patient-centered counseling intervention, and an office support system that screened patients, cued providers to intervene, and made patient education materials available. The primary outcome measures were change in alcohol use from baseline to 6 months as measured by weekly alcohol consumption and frequency of binge drinking episodes. RESULTS: Participants in the special intervention and usual care groups were similar on important background variables and potential confounders except that special intervention participants had significantly higher baseline levels of alcohol usage (P = .01). At 6-month follow-up, in the 91% of the cohort who provided follow-up information, alcohol consumption was significantly reduced when adjusted for age, sex, and baseline alcohol usage (special intervention, -5.8 drinks per week; usual care, -3.4 drinks per week; P = .001). CONCLUSIONS: This study provides evidence that screening and very brief (5- to 10-minute) advice and counseling delivered by a physician or nurse practitioner as part of routine primary care significantly reduces alcohol consumption by high-risk drinkers.

Effect of physician-delivered nutrition counseling training and an office-support program on saturated fat intake, weight, and serum lipid measurements in a hyperlipidemic population: Worcester Area Trial for Counseling in Hyperlipidemia (WATCH).

OBJECTIVE: To evaluate the effectiveness of a training program for physician-delivered nutrition counseling, alone and in combination with an office-support program, on dietary fat intake, weight, and blood low-density lipoprotein cholesterol levels in patients with hyperlipidemia. PARTICIPANTS AND METHODS: Forty-five primary care internists at the Fallon Community Health Plan, a central Massachusetts health maintenance organization, were randomized by site into 3 groups: (1) usual care; (2) physician nutrition counseling training; and (3) physician nutrition counseling training plus an office-support program. Eleven hundred sixty-two of their patients with blood total cholesterol levels in the highest 25th percentile, having previously scheduled physician visits, were recruited. Physicians in groups 2 and 3 attended a 3-hour training program on the use of brief patient-centered interactive counseling and the use of an office-support program that included in-office prompts, algorithms, and simple dietary assessment tools. Primary outcome measures included change at 1-year of follow-up in percentage of energy intake from saturated fat; weight; and blood low-density lipoprotein cholesterol levels. RESULTS: Improvement was seen in all 3 primary outcome measures, but was limited to patients in group 3. Compared with group 1, patients in group 3 had average reductions of 1.1 percentage points in percent of energy from saturated fat (a 10.3% decrease) (P = .01); a reduction in weight of 2.3 kg (P<.001); and a decrease of 0.10 mmol/L (3.8 mg/dL) in low-density lipoprotein cholesterol level (P = .10). Average time for the initial counseling intervention in group 3 was 8.2 minutes, 5.5 minutes more than in the control group. CONCLUSION: Brief supported physician nutrition counseling can produce beneficial changes in diet, weight, and blood lipids.

A residents' training program for the development of smoking intervention skills.

This article describes the results of a three-hour training program that teaches residents a patient-centered counseling approach to smoking cessation, emphasizing questioning and exploring feelings, rather than providing information. Fifty internal medicine and family practice residents affiliated with a university medical center were assessed before and after training using questionnaires and videotape documenting changes in their knowledge about smoking, attitudes concerning intervention, and intervention skills. The residents showed a significant increase in knowledge and perceived themselves as having significantly more influence on their patients who smoke after completion of the training program. Counseling skills improved significantly in the use of questions and exploring feelings as judged by blind evaluation of videotapes. The results of this three-hour training program suggest that physicians in training are responsive to the teaching of specialized skills deemed important for promoting health behavior changes in their patients.

Measuring the effect of a worksite-based nutrition intervention on food consumption.

Although current dietary guidelines focus on a combination of specific nutrients and food items, most effective dietary interventions focus on patterns of dietary intake and take into account the relationships among nutritional factors. In a controlled nutrition intervention conducted at 16 workplaces, a self-administered health habits questionnaire (HHQ) including a 67-item version of a semiquantitative food frequency questionnaire (FFQ) was distributed prior to a 15-month intervention and again after it. Principal components analysis (PCA) was used to reduce this large set of highly correlated FFQ food items to a smaller set of maximally uncorrelated components (PCs). Of the eight discrete food-based eating patterns targeted in the Treatwell intervention, six were highly correlated ([r[ > or = 0.48) with at least one PC each. This indicates a high level of concordance between a priori intervention targets and actual behavior. Based on log-transformed preintervention FFQ measures, our results showed that a very high proportion (0.55) of the variance in the FFQ data was explained by the PCs. A significantly greater increase in consumption of total vegetables and a larger decrease in dietary intake of ground and processed meats were observed among intervention companies. A comparison PCA conducted on intervention and control companies after the intervention indicated that patterns of intake were very stable over time.

Lung cancer mortality after 16 years in MRFIT participants in intervention and usual-care groups. Multiple Risk Factor Intervention Trial.

PURPOSE: The Multiple Risk Factor Intervention Trial (MRFIT), a randomized clinical trial for the primary prevention of coronary heart disease, enrolled 12,866 men (including 8194 cigarette smokers) aged 35-57 years at 22 clinical centers across the United States. Participants were randomized either to special intervention (SI), which included an intensive smoking cessation program, or to usual care (UC). After 16 years of follow-up, lung cancer mortality rates were higher in the SI than in the UC group. Since rates of smoking cessation in SI were higher than those for UC for the 6 years of the trial, and since risk of lung cancer mortality is known to decline with smoking cessation, these results were unexpected. The purpose of the present study was to investigate hypotheses that could explain the higher observed lung cancer mortality rates in the SI as compared with the UC group. METHODS: Analytic methods were employed to determine whether SI and UC participants differed either in baseline characteristics or in characteristics that changed during the trial and to determine whether these differences could explain the higher rates of lung cancer mortality among SI as compared to UC participants. Rates of mortality from coronary heart (CHD) were examined to explore the possibility that prevention of CHD death may have contributed to greater mortality due to lung cancer in the SI group. RESULTS: From randomization through December 1990, 135 SI and 117 UC participants died from lung cancer. The relative difference between the SI and U groups adjusted for age and number of cigarettes smoked per day, was 1.17 (95% CI:0.92-1.51). The greatest difference between the SI and UC groups in lung cancer mortality rates occurred among the heaviest smokers at baseline who did not achieve sustained smoking cessation by year 2. In this group the rates of death from CHD were approximately the same among the SI and UC subjects. No differences in baseline characteristics were found between SI and UC smokers who did not achieve sustained cessation by year 2, and there were no differences in follow-up characteristics between the two study groups that could explain the difference in lung cancer mortality. CONCLUSIONS: None of the hypotheses proposed to explain the unexpected higher rates of lung cancer mortality among SI as compared with UC subjects were sustained by the data. Thus we conclude that the difference observed is due to chance, and that a longer period of sustained smoking cessation plus follow-up is necessary to detect a reduction in lung cancer mortality as a result of smoking cessation intervention in a randomized clinical trial.

Effects on blood pressure of a decrease in sodium use in institutional food preparation: the Exeter-Andover Project.

To judge the effect on blood pressure, sodium intake of students at two boarding high schools was reduced by 15-20% through changes in food purchasing and in preparation practices in the schools' kitchens. Students were not asked to change their usual eating habits. Each school served alternately as the control or intervention school for one school year. Blood pressure was monitored among 341 subjects during control years and 309 subjects during intervention years. Analysis of blood pressure differences between early in the school year and near the end of the school year, with adjustment for sex and initial blood pressure, showed the effect of the dietary intervention to be -1.7 mmHg for systolic (95% CI = -0.6, -2.9, p = 0.003) and -1.5 mmHg for diastolic pressure (95% CI = -0.6, -2.5, p = 0.002). Such modest and easily attainable changes in sodium intake, if maintained, could have a significant effect on the future risk of essential hypertension among young people.

Provider education to promote implementation of clinical practice guidelines.

STUDY OBJECTIVES: Although the interest in and promulgation of clinical practice guidelines have significantly increased in the past 2 decades, concern exists about their actual implementation. This article focuses on one strategy to encourage guideline implementation at the clinician level: clinician education. The objectives of the article are to review educational strategies, to consider them within the context of complementary strategies carried out at the organizational and clinic setting levels, and to outline challenges and recommendations for clinicians' continuing education. METHODS: Experience and data from relevant randomized clinical trials within an educational framework are reviewed. OBSERVATIONS: Implementation of clinical practice guidelines requires a variety of skills, including assessment, appropriate delineation of a treatment and monitoring plan, patient tracking, and patient counseling and education skills. Continuing education strategies must reflect the content and teaching methods that best match the learning objectives. The pressures of current-day practices place limits on the resources, particularly clinician time, that are available for continuing education. Organizational resources must be committed to build the complementary supportive systems necessary for improved clinician practice. In addition to physicians, education must be directed at nonphysician clinicians, office staff, and administrators who also are responsible for guideline implementation. CONCLUSIONS: To meet the challenges of developing clinician motivation, balancing competing demands, and treating patients with complex medical conditions, all within time constraints, clinical leaders need to design education activities that have leadership support, reflect compelling evidence, use multiple strategies and teaching techniques, and engage learners in skill building and problem solving.

Social desirability bias in dietary self-report may compromise the validity of dietary intake measures.

BACKGROUND: Self-report of dietary intake could be biased by social desirability or social approval thus affecting risk estimates in epidemiological studies. These constructs produce response set biases, which are evident when testing in domains characterized by easily recognizable correct or desirable responses. Given the social and psychological value ascribed to diet, assessment methodologies used most commonly in epidemiological studies are particularly vulnerable to these biases. METHODS: Social desirability and social approval biases were tested by comparing nutrient scores derived from multiple 24-hour diet recalls (24HR) on seven randomly assigned days with those from two 7-day diet recalls (7DDR) (similar in some respects to commonly used food frequency questionnaires), one administered at the beginning of the test period (pre) and one at the end (post). Statistical analysis included correlation and multiple linear regression. RESULTS: Cross-sectionally, no relationships between social approval score and the nutritional variables existed. Social desirability score was negatively correlated with most nutritional variables. In linear regression analysis, social desirability score produced a large downward bias in nutrient estimation in the 7DDR relative to the 24HR. For total energy, this bias equalled about 50 kcal/point on the social desirability scale or about 450 kcal over its interquartile range. The bias was approximately twice as large for women as for men and only about half as large in the post measures. Individuals having the highest 24HR-derived fat and total energy intake scores had the largest downward bias due to social desirability. CONCLUSIONS: We observed a large downward bias in reporting food intake related to social desirability score. These results are consistent with the theoretical constructs on which the hypothesis is based. The effect of social desirability bias is discussed in terms of its influence on epidemiological estimates of effect. Suggestions are made for future work aimed at improving dietary assessment methodologies and adjusting risk estimates for this bias.

Nicotine replacement prescription practices of obstetric and pediatric clinicians.

OBJECTIVE: To assess smoking cessation counseling and nicotine replacement therapy prescription and recommendation practices among obstetric and pediatric providers. METHODS: We sent out a self-administered survey to 61 obstetric and pediatric nurse practitioners and physicians at six community health centers in the Boston area. RESULTS: Obstetric providers were more likely to view smoking cessation counseling as their responsibility in treating pregnant women than pediatric providers did in treating infants with mothers who smoked (mean +/- standard deviation [95% confidence interval] 4.5 +/- 0.76 [4.2, 4.8] versus 4.0 +/- 0.8 [3.7, 4.3] on a five-point scale; P <.05). Obstetric providers believed that smoking cessation counseling was more effective than did pediatric providers (3.45 +/- 1.1 [3.0, 3.9] versus 2.8 +/- 0.8 [2.5, 3.1] on a five-point scale; P <.05) and were more likely to report provision of cessation assistance than pediatric providers (63% [44%, 82%] versus 17% [5%, 29%]; P <.05). Obstetric providers were more likely to prescribe or recommend over-the-counter nicotine replacement therapy than pediatric providers (44% [25%, 63%] versus 11% [1%, 21%], P =.004). Reasons for not prescribing nicotine replacement differed according to specialty; however, perceived lack of efficacy was not a typical reason given by clinicians in either specialty. Only two of 47 practitioners who did not prescribe or recommend those therapies listed that as a factor in their decisions. CONCLUSION: We found that nicotine replacement therapies are commonly prescribed or recommended to pregnant smokers by obstetric providers, but less commonly to lactating women by pediatric providers.

Teaching risk-factor counseling skills to medical students, house staff, and fellows.

It is important to teach risk-factor counseling skills to medical students, primary care residents, and fellows in cardiovascular medicine. To do this, it is necessary to teach assessment and intervention skills based on the theory and techniques of preventive and behavioral medicine. Physicians should be taught to think in terms of the patient in the context of his or her lifestyle and other interacting factors affecting health and disease, and should develop a new medical "culture" within which the risk-factor and lifestyle antecedents and correlates of illness can be recognized, discussed, and approached therapeutically. In this approach to physician training, risk-factor intervention skills training is integrated into existing teaching vehicles to minimize the burden on the curriculum and maximize the extent to which the material can be incorporated into the daily practice of medicine. The objectives associated with training in behavioral medicine skills and examples demonstrating how specific teaching vehicles that are already established in most institutions can be used to accomplish this training are presented. Strategies for motivating physicians to practice prevention with their parents also are discussed.

Heavy smoking among a sample of employed women.

Understanding the phenomenon of heavy smoking among women and factors related to it is of considerable public health importance. Whereas lighter smokers have been more successful in their cessation attempts, the percentage of smokers who smoke more than 25 cigarettes per day has increased in recent years. This article examines the hypothesis that, compared to lighter smokers, female heavy smokers will report more responsiveness to internal cues to smoke, less interest in quitting, more difficulty with previous cessation attempts, more uncertainty about cessation strategies, and more concern about weight gain as a result of quitting. We collected data in 1984 through a self-administered survey completed by 874 women employed as nurses in acute care, chronic care, and home care nursing in Worcester, Massachusetts; we base our analyses on data collected from 158 light and moderate smokers and 67 heavy smokers. Our findings suggest that, compared to lighter smokers, heavy smokers may depend more on nicotine and are likely to respond to a broader array of cues to smoke, factors that appear to contribute to heavy smokers' greater difficulties with quitting. These female heavy smokers are just as likely as lighter smokers to have made previous attempts to quit and want to quit just as much. Major barriers to quitting for female heavy smokers include a lack of confidence in their ability to quit, insufficient tools to succeed with cessation attempts, and fear that weight gain will accompany quitting.

A survey of Massachusetts physicians' smoking intervention practices.

Attitudes toward smoking intervention, and the intervention practices of 65 residents, 51 attending physicians, and 292 community physicians in central and western Massachusetts were assessed through a mailed questionnaire. Nearly all physicians reported that they obtained information on the smoking status of new patients and told smokers to quit. Proportionately fewer physicians, however, reported that they counseled their patients on how to stop smoking; those who did, did so for relatively brief periods of time. After differences in physician age and smoking status were controlled for, residents were significantly more likely than attending physicians to counsel their patients on how to stop smoking, but were also more likely (than attending and community physicians) to recommend or refer their patients to formal smoking cessation programs. A small percentage of the physicians responding (3%-16%) reported that they were prepared to counsel smokers, but most reported that information on where to refer patients, smoking cessation techniques, and skills training would be of great value. The results of this survey suggest practical differences between residents and attending and community physicians in approaching patients who smoke and in attitudes toward the need for additional skills and financial and organizational assistance.

Severity of angiographically proven coronary artery disease predicts smoking cessation.

We investigated the relationship between the extent of coronary artery disease (CAD) and the likelihood of cigarette smoking cessation in a population of 84 smokers between 21 and 75 years of age undergoing elective or urgent coronary angiography at the University of Massachusetts Medical Center. The smokers were enrolled in a pilot study investigating the relationship of hospitalization and coronary arteriography for coronary artery disease to subsequent smoking cessation and were scored at baseline as having none, one-, two-, or three-vessel disease. Smoking status at a mean follow-up time of 11 months was obtained by telephone interview, at which point 50% reported not smoking. Logistic regression showed a significant relationship between smoking cessation and two factors: the anatomic extent of CAD and the experience of having had coronary artery bypass surgery or percutaneous transluminal coronary angioplasty following the initial catheterization. We discuss the relative roles of patient knowledge and motivation and physician intervention, and their implications for smoking cessation interventions.

Effect of training and a structured office practice on physician-delivered nutrition counseling: the Worcester-Area Trial for Counseling in Hyperlipidemia (WATCH).

We examined the effectiveness of a training program for physician-delivered nutrition counseling, alone and in combination with a structured office practice environment for nutrition management, on physicians' counseling practices. Forty-five primary care internists and 1,278 of their patients in the top quarter of the cholesterol distribution at a central Massachusetts health maintenance organization (the Fallon Clinic) were enrolled into a randomized controlled trial. Physicians were randomized by site into three conditions: (1) usual care, (2) physician nutrition counseling training, and (3) physician nutrition counseling training plus a structured office practice environment for nutrition management (prompts and the provision of lipid results and counseling algorithms). A randomly selected 325 patients were given a 10-item patient exit interview (PEI) assessing whether the physician provided advice; assessed past changes, barriers, and resources; negotiated specific plans and goals; provided patient materials; referred the patient to a dietitian; and developed plans for follow-up. Condition 3 physicians demonstrated significantly greater implementation of the nutrition counseling sequence than did physicians in either of the other two conditions (P < .0001). Referrals to nutrition services were markedly reduced in condition 2, despite PEI scores no different than those in condition 1. Higher PEI scores for patients seen by physicians in condition 3 were stable for as long as two years beyond training. Primary care internists, when provided with both training in counseling techniques and a supportive office environment, will carry out patient counseling appropriately. Training alone, however, is not sufficient and may be counterproductive. Medical Subject Headings (MeSH): hypercholesterolemia, diet therapy, coronary disease, health behavior, primary health care, medical education, managed care programs.

Are we pushing the limits of public health interventions for smoking cessation?

The phenomenon of smoking cessation that takes place outside formal programs, which serve a small proportion of smokers, is an important public health issue. Self-help strategies represent an approach to potentially cost-effective smoking intervention that can be conveniently used by large groups of smokers. In this issue of Health Psychology, Gritz, Berman, Bastani, and Wu (1992) demonstrate that the mailing of self-help smoking cessation materials to nonvolunteer women in a health maintenance organization, without any personal contact, produces little behavior change beyond what occurs in the environment without such distribution. This outcome is not surprising and does not illiminate the possibility of efficacious use of self-help materials with a nonvolunteer population. An essential question is: Could these materials have been distributed in such a way as to increase their use and eventual efficacy? Efforts to attract more smokers to use existing materials are an essential element of self-help strategies. An effective public health approach is a comprehensive one that successfully engages the individual and, through multiple channels in the community, provides reinforcement, supports, and norms for not smoking.
