Direct observation of nutrition counseling in community family practice

Lifestyle Medicine in Medical Education: Maximizing Impact

The relationship between lifestyle behaviors and common chronic conditions is well established. Lifestyle medicine (LM) interventions to modify health behaviors can dramatically improve the health of individuals and populations. There is an urgent need to meaningfully integrate LM into medical curricula horizontally across the medical domains and vertically in each year of school and training. Including LM content in medical and health professional curricula and training programs has been challenging. Barriers to LM integration include lack of awareness and prioritization of LM, limited time in the curricula, and too few LM-trained faculty to teach and role model the practice of LM. This limits the ability of health care professionals to provide effective LM and precludes the wide-reaching benefits of LM from being fully realized. Early innovators developed novel tools and resources aligned with current evidence for introducing LM into didactic and experiential learning. This review aimed to examine the educational efforts in each LM pillar for undergraduate and graduate medical education. A PubMed-based literature review was undertaken using the following search terms: lifestyle medicine, education, medical school, residency, and healthcare professionals. We map the LM competencies to the core competency domains of the Accreditation Council for Graduate Medical Education. We highlight opportunities to train faculty, residents, and students. Moreover, we identify available evidence-based resources. This article serves as a "call to action" to incorporate LM across the spectrum of medical education curricula and training.

Nutrition and Physical Activity Counseling by General Practitioners in China

Introduction

To reduce unhealthy lifestyles in China, it is critical to implement effective strategies. Counseling provided by physicians is important for assisting patients in improving their lifestyles, and general practitioners (GPs) are the main providers of lifestyle counseling to patients. However, few studies have focused on the lifestyle counseling practices by GPs in China, particularly in regard to nutrition and physical activity.

Objective

The aims of this study are: (i) to examine the current practice of Chinese GPs in counseling patients regarding nutrition and physical activity; (ii) to understand the common barriers to such counseling by Chinese GPs; and (iii) to study the association between GPs' personal lifestyle choices and their practices in lifestyle counseling.

Methods

A cross-sectional, self-reported online questionnaire was conducted among GPs in Hunan province, China. A total of 198 GPs completed the questionnaire.

Results

The majority of GPs provide nutrition and physical activity counseling to less than 40% of their patients, spending less than three minutes per counseling session. The main reported barriers to counseling on nutrition and physical activity are inadequate time and a lack of knowledge or experience. GPs primarily acquire knowledge through medical books and journals, followed by science popularization. Furthermore, GPs who maintain healthier lifestyle habits, possess a better understanding of lifestyle guidelines, conduct longer office visits, and exhibit higher self-efficacy are more likely to provide counseling to patients.

Conclusion

This study highlights the need for improvement in nutrition and physical activity counseling among Chinese GPs. GPs' personal nutrition and physical activity habits may measurably influence their counseling practice. We recommend that GPs themselves adopt healthier lifestyle habits to potentially improve their counseling practice. Moreover, proactive measures should be taken to assist GPs in overcoming barriers encountered with lifestyle counseling.

User-Centered Design of a Clinical Tool for Shared Decision-making About Diet in Primary Care

BACKGROUND

Health information technology is a leading cause of clinician burnout and career dissatisfaction, often because it is poorly designed by nonclinicians who have limited knowledge of clinicians' information needs and health care workflow.

OBJECTIVE

Describe how we engaged primary care clinicians and their patients in an iterative design process for a software application to enhance clinician-patient diet discussions.

DESIGN

Descriptive study of the steps followed when involving clinicians and their at-risk patients in the design of the content, layout, and flow of an application for collaborative dietary goal setting. This began with individual clinician and patient interviews to detail the desired informational content of the screens displayed followed by iterative reviews of intermediate and final versions of the program and its outputs.

PARTICIPANTS

Primary care clinicians practicing in an urban federally qualified health center and two academic primary care clinics, and their patients who were overweight or obese with diet-sensitive conditions.

MAIN MEASURES

Descriptions of the content, format, and flow of information from pre-visit dietary history to the display of evidence-based, guideline-driven suggested goals to final display of dietary goals selected, with information on how the patient might reach them and patients' confidence in achieving them.

KEY RESULTS

Through three iterations of design and review, there was substantial evolution of the program's content, format, and flow of information. This involved "tuning" of the information desired: from too little, to too much, to the right amount displayed that both clinicians and patients believed would facilitate shared dietary goal setting.

CONCLUSIONS

Clinicians' well-founded criticisms of the design of health information technology can be mitigated by involving them and their patients in the design of such tools that clinicians may find useful, and use, in their everyday medical practice.

Are primary care providers' nutrition care and food insecurity screening practices associated with their perceptions of team-based care?

BACKGROUND

Screening for food insecurity (FI) and providing nutrition care are important management strategies for chronic diseases, but rates are low. Aspects of team-based care and providers' nutrition competence may help inform interventions to improve these services. The objectives of this study were to describe US primary care providers' FI screening and nutrition care practices (counselling, referrals, and time spent counselling) and test for associations with scored measures of their perceptions of team-based care (care continuity, patient-centredness, coordination with external providers and resources) and nutrition competence (confidence counselling and attitudes towards nutrition).

METHODS

Cross-sectional online survey data of primary care providers were described and analysed for associations using Wilcoxon rank sum tests.

RESULTS

Of provider respondents (N = 92), 35% (n = 32) worked in clinics that screen for FI and had higher team perceptions (P = 0.006) versus those who do not. Those who reported counselling >30% patients about nutrition (57%, n = 52) and referring >10% patients to nutrition professionals (24%, n = 22) had significantly better attitudes towards nutrition (P = 0.013 and P = 0.04, respectively) compared with those with lower counselling and referral rates. Half (n = 46) of the providers reported spending >3-min counselling each patient about nutrition and had higher patient-centred care (P = 0.004) and nutrition competence (P < 0.001) compared with those who spent less time counselling.

CONCLUSION

Providers in clinics that screen for FI had higher overall perceptions of team-based care, but their nutrition competence was not significantly different. Meanwhile, reported more time counselling was associated with a culture of patient-centredness. Promoting team-based care may be a mechanism for improving FI screening and nutrition care.

A feasibility study of a randomized controlled trial protocol to assess the impact of an eHealth intervention on the provision of dietary advice in primary care

BACKGROUND

Canadian sodium intakes remain high despite population-wide sodium reduction initiatives, highlighting the need for personal action in reducing dietary sodium. eHealth interventions support patients in dietary change and assist clinicians in decision-making and delivering care, including provision of advice. To date, impact of diet-focused eHealth tools, like the Sodium Calculator (SC) dietary screening tool, on clinical outcomes has received minimal examination. This study assessed feasibility of a randomized controlled trial (RCT) protocol to examine the impact of the SC, a physician-focused intervention, on the quality of dietary sodium reduction advice provided by physicians to their patients with hypertension.

METHODS

Primary care physicians from community-based primary care clinics were randomized to one of two groups: (1) 'usual care' for dietary sodium counselling or (2) dietary sodium counselling using the SC ('experimental group'). The primary endpoint was protocol feasibility defined by the following outcomes: process (e.g. recruitment, retention, protocol adherence, acceptability of intervention), resources (e.g. needs, impact on workflow), and management (e.g. staff requirements). Outcomes were assessed using direct observation, interviews, and questionnaires with patients, physicians, and clinic staff.

RESULTS

Seven physicians (n = 4 in experimental group, n = 3 in usual care group) and 65 patients with hypertension (48.5% men, 69.8 ± 10.1 years) successfully participated. The main challenges identified is related to recruitment rate (48% for patients, 20% for physicians) and physician protocol adherence (76%). These improved with minor protocol modifications. There were several areas of protocol success such as no disruption to physician workflow, hiring clinic nurses as research staff, having a physician site lead to support physician recruitment, and a 'Protocol Prompt Form' to increase physician protocol adherence. Importantly, there was a high degree of acceptability of the SC intervention among experimental group physicians [n = 3 (75%)].

CONCLUSIONS

The modified RCT protocol was considered feasible. The identified successes can be leveraged, and the risks can be mitigated, during implementation of a full-scale RCT. Assessment of this RCT protocol is an important step in understanding the effectiveness of diet-focused eHealth tools to supporting physician self-efficacy in assessing, monitoring, and implementing dietary advice in routine clinical practice and supporting patients in effective behaviour change.

Adherence to COVID-19 nutritional guidelines and their impact on the clinical outcomes of hospitalized COVID-19 patients

Background & aims

Coronavirus disease 2019 (COVID-19) patients are at high risk of malnutrition, and their doctors are part of a multidisciplinary team, including nutritionists. However, adherence to nutritional guidelines may be difficult in the context of capacity constraints during the COVID-19 pandemic. The aim of this study was to investigate barriers to doctors' adherence to nutritional guidelines and the impacts of guideline adherence on the outcomes of hospitalized COVID-19 patients.

Methods

A multinational electronic survey involving 51 doctors was conducted between November 2020 and January 2021 from 17 COVID-19-designated hospitals in countries with high (Indonesia) and low (Vietnam) numbers of confirmed COVID-19 cases.

Results

In general, doctors reported concerns related to nutritional practices in patients with Covid-19 which included feeling stress when performing medical nutritional therapy (65%), lacking self-efficacy or confidence in performing nutritional care (49%), lacking clear nutritional guidelines (45%), and experiencing budget limitations (33%). A regression analysis adjusted for age, country, and the number of hospitalized COVID-19 cases revealed that guideline knowledge (β: −1.01 (−1.78, −0.23); p = 0.012) and awareness of guidelines (β: −1.37 (−2.66, −0.09); p = 0.037) were negatively correlated with the length of stay of critically ill COVID-19 patients, but non-significant after adjusting for specialization of the doctor. When stratified according to country, a significant relationship between guideline adherence and length of stay of critically ill patients was only found in Vietnam [guideline adherence: β: −0.55 (−1.08, −0.03); p = 0.038; guideline knowledge: β: −1.01 (−1.9, −0.13); p = 0.027] after adjusting for age, specialty, and number of hospitalized COVID-19 cases. In Indonesia, the significant relationship between guideline adherence and mortality of COVID-19 patients remained strong (β: −14 (−27, −1); p = 0.033) after adjusting for age, specialty, and number of hospitalized COVID-19 cases

Conclusions

Inadequate nutritional knowledge is a key barrier to guideline adherence, and this was international and may be related to doctors' specialties and the COVID-19 pandemic. Adherence to nutritional guidelines may represent a prognostic factor for survival in COVID-19 patients.

Design and pilot evaluation of an evidence-based worksheet and clinician guide to facilitate nutrition counselling for patients with severe mental illness

BACKGROUND

Schizophrenia spectrum disorders (SSD) are severe, persistent mental illnesses resulting in considerable disability and premature mortality. Emerging evidence suggests that diet may be a modifiable risk factor in mental illness; however, use of nutritional counselling as a component of psychiatric clinical practice is limited. The objective of this project is the design and evaluate a worksheet and clinician guide for use in facilitating nutritional counseling in the context of existing mental health care.

METHODS

The worksheet and clinician guide were developed based on the results of a recent scoping review on the relationship between diet and mental health symptoms among individuals with SSD. A feedback process involved a focus group with psychiatrists and interviews with individuals with lived experience with psychosis. Participants were asked a series of structured and open-ended questions. Interviews were transcribed and data units were allocated to categories from an existing framework. The comments were used to guide modifications to the worksheet and clinician guide. A brief interview with all participants was completed to gather feedback on the final version.

RESULTS

Five psychiatrist participants and six participants with lived experience completed interviews. Participants provided positive comments related to the worksheet design, complexity and inclusion of interactive components. A novel theme emerged relating to the lack of nutritional counselling in psychiatric training and clinical practice. Many constructive comments were provided which resulted in meaningful revisions and improvements to the worksheet and clinician guide design and content. All participants were satisfied with the final versions.

CONCLUSIONS

A worksheet and clinician guide designed to facilitate nutritional counselling with individuals with SSD was found to be acceptable to all participants following a process of feedback and revision. Further research and dissemination efforts aimed at increasing the use of nutritional counselling in psychiatric practice are warranted.

Feasibility of Colocating a Nutrition Education Program into a Medical Clinic Setting to Facilitate Pediatric Obesity Prevention

Purpose:

Within a medical clinic environment, pediatric obesity prevention education for families faces challenges. Existing long-term government-funded nutrition education programs have the expertise and staff to deliver. The purpose is to determine feasibility of colocating the Expanded Food and Nutrition Education Program (EFNEP) into a medical clinic setting to support pediatric obesity prevention.

Methods:

Physicians from a large university teaching and research hospital (n = 73) and 4 small Medicaid-serving community clinics (n = 18) in the same geographic area in northern California were recruited and trained in the patient-referral protocol for a primary prevention intervention provided by EFNEP. The 8-week intervention deployed in the medical clinics, included general nutrition, physical activity and parenting topics anchored with guided goal setting and motivational modeling. Referral, enrollment, and attendance data were collected for 2 years. Parent and physician feasibility surveys, parent interviews and parent risk assessment tools were administered. Paired-sample t-test analysis was conducted.

Results:

Twenty intervention series with parents of patients (n = 106) were conducted at 5 clinics. Physicians (n = 92) generated 686 referrals. Every 6 referrals generated 1 enrolled parent. Physicians (91%, n = 34) reported the intervention as useful to families. Parents (n = 82) reported improved child behaviors for sleep, screen time, physical activity, and food and beverage offerings (P < .0001) and at family mealtime (P < .001). Focus group interviews (n = 26) with 65 participants indicated that parents (97%) reacted positively to participating in the intervention with about a third indicating the classes were relevant to their needs.

Conclusion:

The intervention is a feasible strategy for the 5 medical clinics. Physicians referred and parents enrolled in the intervention with both physicians and parents indicating positive benefits. Feasibility is contingent upon physician awareness of the intervention and motivation to refer patients and additional EFNEP and clinic staff time to enroll and keep parents engaged.

Nutrition, a Tenet of Lifestyle Medicine but Not Medicine?

Nutrition is a foundation of health and one of six pillars of Lifestyle Medicine. The importance of nutrition in clinical care is now widely recognized by health care professionals and the public. However, clinicians are not comfortable counselling their patients on nutrition due to inadequate or lack of training, leaving a significant need in patient care. This gap can be closed with evidence-based curricula in medical schools and in the trainings of other health care professionals. This communication presents the current state of nutrition knowledge in health care, emphasizing nutrition education for physicians, and presents a model of how pre- through post-professional health care providers may become proficient in nutrition counseling including appropriate referral to more specialized providers. With these skills, health care professionals will be able to initiate patient-centered lifestyle plans. This includes improving diet and utilization of team-based medicine and referrals.

Knowledge, Attitudes and Behaviours Related to Physician-Delivered Dietary Advice for Patients with Hypertension

Dietary modifications are key health behaviour recommendations for the prevention and management of hypertension, a leading contributor of global disease burden. Despite this, few primary care physicians discuss nutrition with their patients. This study describes the barriers and facilitators to the provision of dietary advice for hypertension prevention and management among Canadian physicians. A validated 62-item cross-sectional survey was distributed online to 103 Canadian primary care physicians between 2017 and 2019. Eighty participants were included in the analyses. The majority of participants were based in Ontario (68.7%) and saw 10-24 patients per week (53.5%). Fewer than half (47.5%) of participants were knowledgeable about the recommended sodium level by Hypertension Canada (< 2000 mg/day) and 38.8% felt it was difficult to know which foods are high or low in sodium. Approximately one quarter felt the findings about sodium and hypertension and cardiovascular disease are controversial. Other significant barriers were: not enough time to talk to patients about diet (76.3%), belief that patients are not truthful about their diet (76.3%), patients would not follow their advice (46.8%), and that it was difficult to keep up with so many guidelines (50.0%). Many identified that electronic medical record tools (80.8%), access to dietitians (84.9%), or more nutrition education in medical training (65.8%) would help facilitate advice. Given the importance of diet and the central role of physicians in motivating dietary change among patients, approaches are required to address identified barriers and facilitators to providing dietary advice to reduce the burden of hypertension.

Dietary guidelines training may improve health promotion practice: Results of a controlled trial in Brazil

BACKGROUND

The double burden of malnutrition points to an urgent need to develop strategies to promote healthy diets. Health professionals are key elements for health promotion and must be prepared to deal with these issues in health services.

AIM

This study aimed to evaluate the impact of an educational intervention based on Brazilian Dietary Guidelines in the practice of multidisciplinary teams working in primary health care.

METHODS

A controlled trial comprising pre- and post-tests was conducted with four multidisciplinary healthcare teams. The intervention group received 16 hours of training on the Brazilian Dietary Guidelines. The professionals' practices were evaluated by direct observation, before and after the intervention, for two months at each timepoint. Data on dietary counselling were collected using a previously validated scale. The Kruskal-Wallis test was used for intragroup comparison at T0 versus T1, and the intergroup effects of the intervention were estimated by generalized linear regression analysis with a 95% confidence interval.

RESULTS

The regression with the interaction term between the intervention group and time showed a positive effect of the educational intervention on professionals' practices in the intervention group in the crude and adjusted models (coefficient = 1.36 and p = 0.020). Brazilian Dietary Guidelines application significantly increased in non-nutritionist professionals' practices (p = 0.007) and in activities not related to nutrition (p = 0.028) in the intervention group over time (T1-T0). No significant differences were found in the control group.

CONCLUSION

The intervention proved to be effective in promoting changes in health professionals' practices, demonstrating the strength of the strategy for dissemination of nutrition guidelines in primary health care.

Goals in Nutrition Science 2020-2025

Five years ago, with the editorial board of Frontiers in Nutrition, we took a leap of faith to outline the Goals for Nutrition Science - the way we see it (1). Now, in 2020, we can put ourselves to the test and take a look back. Without a doubt we got it right with several of the key directions. To name a few, Sustainable Development Goals (SDGs) for Food and Nutrition are part of the global public agenda, and the SDGs contribute to the structuring of international science and research. Nutritional Science has become a critical element in strengthening work on the SDGs, and the development of appropriate methodologies is built on the groundwork of acquiring and analyzing big datasets. Investigation of the Human Microbiome is providing novel insight on the interrelationship between nutrition, the immune system and disease. Finally, with an advanced definition of the gut-brain-axis we are getting a glimpse into the potential for Nutrition and Brain Health. Various milestones have been achieved, and any look into the future will have to consider the lessons learned from Covid-19 and the sobering awareness about the frailty of our food systems in ensuring global food security. With a view into the coming 5 years from 2020 to 2025, the editorial board has taken a slightly different approach as compared to the previous Goals article. A mind map has been created to outline the key topics in nutrition science. Not surprisingly, when looking ahead, the majority of scientific investigation required will be in the areas of health and sustainability.

Healthcare provider counselling for weight management behaviours among adults with overweight or obesity: a cross-sectional analysis of National Health and Nutrition Examination Survey, 2011-2018

OBJECTIVES

To determine if adults with overweight or obesity received counselling from their healthcare providers (HCPs) to lose weight and/or adopt healthful behaviours associated with weight loss, and whether they took action on their HCPs' recommendations.

DESIGN

Cross-sectional analysis of 2011-2018 National Health and Nutrition Examination Survey (NHANES) data.

SAMPLE

NHANES respondents aged 18+ who were overweight/obese and had seen an HCP in the previous 12 months (n=13 158).

METHODS

Respondents reported if their HCPs recommended they control/lose weight, increase exercise/physical activity (PA) and/or reduce fat/calorie intake, and if they adopted the offered recommendation(s). Weighted logistic regression models examined receipt of HCP counselling by sex, age, race/ethnicity, and weight status accounting for demographic characteristics and complex sampling. Similar analyses examined reported adoption of HCPs' recommendations.

RESULTS

The sample was 53.1% women, 45.0% were overweight and 55.0% had obesity. In total, 40.4% received counselling to control/lose weight, 49.5% to increase exercise/PA and 38.9% to reduce fat/calorie intake. The following groups were less likely (p<0.001) to receive counselling: men; younger adults (aged 18-39) versus middle-aged (aged 40-64) and older adults (aged 65+); White versus Black and Hispanic respondents; overweight respondents versus respondents with obesity. Approximately half of those advised to make changes reported doing so (53.6% controlled/lost weight, 57.3% increased exercise/PA, 51.8% reduced fat/calorie intake). Differences in the adoption of recommendations were identified by sex, age group, race/ethnicity and weight status (all p<0.05); women, middle-aged and older adults, Black and Hispanic respondents and individuals with obesity were more likely to adopt one or more recommendations.

CONCLUSION

Most respondents did not receive HCP counselling, and approximately half of those who received counselling reported taking action. HCPs may need training to provide counselling and to offer recommendations tailored to the social contexts of populations less likely to adopt weight control related recommendations.

Australian and New Zealand Medical Students' Attitudes and Confidence Towards Providing Nutrition Care in Practice

The prevalence of lifestyle-related chronic disease is increasing. Doctors in primary care are ideally placed to support patient nutrition care, but recent reviews show education is still lacking. This study aimed to identify medical students’ attitudes towards the role of nutrition in health, nutrition knowledge, and perceptions of nutrition education, in postgraduate (Australia) and undergraduate (New Zealand) programs in order to identify gaps in nutrition knowledge and skills to better inform future education. Second-year graduate and third-year undergraduate students participated in semi-structured focus groups and interviews. A general inductive approach was used to investigate students’ (1) attitudes toward the role of nutrition in health, (2) nutrition knowledge based on nutrition-specific competencies and (3) perceived adequacy of nutrition education received. Interviews (nine) and focus groups (seven) identified four common themes: (1) role of medical practitioners in nutrition care, (2) barriers to nutrition education, (3) nutrition knowledge, and (4) nutrition-related skills. Students perceive that doctors are well-placed to provide some level of nutrition care, but poor translation of nutrition knowledge to clinical contexts is a key limitation in nutrition education. In summary, nutrition education may be insufficient to support the nutrition-related competency development of the undergraduate and postgraduate student participants in this study. Focusing on the integration of these skills into the curriculum may be a priority.

"You Guys Really Care About Me…": a Qualitative Exploration of a Produce Prescription Program in Safety Net Clinics

BACKGROUND

Although research shows produce prescription (PRx) programs increase fruit and vegetable (FV) consumption, little is known about how participants experience them.

OBJECTIVE

To better understand how participants experience a PRx program for hypertensive adults at 3 safety net clinics partnered with 20 farmers' markets (FMs) in Cleveland, OH.

DESIGN

We conducted semi-structured interviews with 5 program providers, 23 patient participants, and 2 FM managers.

PARTICIPANTS

Patients interviewed were mainly middle-aged (mean age 62 years), African American (100%), and women (78%). Providers were mainly middle-aged men and women of diverse races/ethnicities.

INTERVENTION

Healthcare providers enrolled adult patients who were food insecure and diagnosed with hypertension. Participating patients attended monthly clinic visits for 3 months. Each visit included a blood pressure (BP) check, dietary counseling for BP control, a produce prescription, and produce vouchers redeemable at local FMs.

APPROACH

Patient interviews focused on (1) beliefs about food, healthy eating, and FMs; (2) clinic-based program experiences; and (3) FM experiences. Provider and market manager interviews focused on program provision. All interviews were audio-taped, transcribed, and analyzed thematically.

KEY RESULTS

We identified four central themes. First, providers and patients reported positive interactions during program activities, but providers struggled to integrate the program into their workflow. Second, patients reported greater FV intake and FM shopping during the program. Third, social interactions enhanced program experience. Fourth, economic hardships influenced patient shopping and eating patterns, yet these hardships were minimized in some participants' views of patient deservingness for program inclusion.

CONCLUSIONS

Our findings highlight promises and challenges of PRx programs for economically disadvantaged patients with a chronic condition. Patient participants reported improved interactions with providers, increased FV consumption, and incorporation of healthy eating into their social networks due to the program. Future efforts should focus on efficiently integrating PRx into clinic workflows, leveraging patient social networks, and including economic supports for maintenance of behavior change.

Catalysts for Change: Accelerating the Lifestyle Medicine Movement Through Professionals in Training

While the Western diet has evolved to become increasingly high in saturated fat, cholesterol, protein, sugar, and salt intake, nutrition education and training of health care professionals to counsel their patients on the hazards of such a diet has trailed behind. Primary care physicians have an opportunity to bridge the gap by providing nutrition and dietary counseling as key components in the delivery of preventive services. Increasing research points to the value of a whole-foods plant-based diet in combating chronic disease, yet the knowledge of health professionals about the topic is comparable to that of the general public. This education crisis is apparent in medical training with restricted time for dedicated lectures on nutrition, physical activity, restorative sleep, emotional well-being, and avoidance of risky substance use. Together, educators and learners are valuable catalysts for culture change in medical education, training, and clinical practice. Barriers to physician ability to counsel about lifestyle are many, but one that stands out is lack of training and comfort with counseling. This has implications for the training of health care professionals. American College of Lifestyle Medicine has a committee, Professionals in Training, composed of interprofessional and multidisciplinary students, residents, and fellows nationally and worldwide who are committed to expanding exposure to lifestyle medicine and implementation of lifestyle medicine in parallel curriculum and personal care.

Beyond Nutrition Knowledge and Tools-What Do Pediatric Providers Really Need?

Nutrition counseling continues to be a concern for pediatric providers. This study aimed to extend the understanding of the perceptions of pediatric providers regarding nutrition care. Individual semi-structured qualitative interviews were conducted using a purposive sampling technique. Interviews were conducted in-person or via telephone, recorded, and transcribed. Seven themes emerged from the data and these can be used as a "how to" for medical educators. Based on the experiences and perspectives of the pediatric providers in our study, we are moving forward with the systematic development of a curriculum to improve nutrition care and counseling in pediatrics.

Nutrition Counseling for Hypertension Within a Grocery Store: An Example of the Patient-Centered Medical Neighborhood Model

OBJECTIVE

To evaluate the effectiveness of nutrition counseling for patients with hypertension, provided in a grocery store setting.

DESIGN

Single-arm pretest-posttest design implementing a 12-week dietary intervention.

SETTING

Grocery store.

PARTICIPANTS

Thirty adults with hypertension recruited from a primary care practice.

INTERVENTION

Registered dietitian nutritionists provided counseling based on the Dietary Approaches to Stop Hypertension diet.

MAIN OUTCOME MEASURES

Dietary intake patterns and Healthy Eating Index-2010 (HEI-2010) scores measured via food-frequency questionnaire. Change in systolic blood pressure (SBP) was a secondary outcome.

ANALYSIS

Paired t tests were used to test for differences between HEI-2010 scores, intake of key food pattern components, and SBP at baseline compared with follow-up. Statistical significance was established at P ≤ .05.

RESULTS

Eight HEI-2010 component scores increased significantly from baseline to follow-up (a change toward a more desirable eating pattern): total fruit, whole fruit, greens and beans, whole grains, fatty acids, refined grains, and empty calories. Sodium (P < .001), saturated fat (P < .001), discretionary solid fat (P < .001), added sugars (P = .01), and total fat (P < .001) all decreased significantly. The change in SBP was not significant.

CONCLUSIONS AND IMPLICATIONS

Grocery store-based counseling for patients with hypertension may be an effective strategy to provide lifestyle counseling that is not typically available within primary care.

Dietetic Staffing and Workforce Capacity Planning in Primary Health Care

The addition of Registered Dietitians (RD) to primary health care (PHC) teams has been shown to be effective in improving health and economic outcomes with reported savings of $5 to $99 New Zealand dollars for every $1 spent on nutrition interventions. Despite proven benefits, very few Canadians have access to dietitians in PHC. This paper summarizes the literature on dietetic staffing ratios in PHC in Canada and other countries with similar PHC systems. Examples are shared to demonstrate how dietitians and others can utilize published staffing ratios to review dietitian services within their settings, identify gaps, and advocate for additional positions to meet population needs. The majority of published dietetic staffing ratios describe ranges of 1 RD: 15 000-18 500 patients, 1 RD for every 4-14 family physicians, or 1 RD for every 300-500 patients with diabetes. These staffing ratios may be inadequate as surveys report ongoing issues of limited access to dietetic counseling, under-serviced populations, and a shortage of dietitians to meet current population needs in PHC. Newer projection models based on specific population needs and ongoing workforce data are required to identify professional practice issues and accurately estimate dietetic staffing requirements in PHC.

Patient and Physician Race and the Allocation of Time and Patient Engagement Efforts to Mental Health Discussions in Primary Care: An Observational Study of Audiorecorded Periodic Health Examinations

This study investigated racial differences in patient-physician communication around mental health versus biomedical issues. Data were collected from audiorecorded periodic health examinations of adults with mental health needs in the Detroit area (2007-2009). Patients and their primary care physicians conversed for twice as long, and physicians demonstrated greater empathy during mental health topics than during biomedical topics. This increase varied by patient and physician race. Patient race predicted physician empathy, but physician race predicted talk time. Interventions to improve mental health communication could be matched to specific populations based on the separate contributions of patient and physician race.

Sugar-Sweetened Beverage Intake Assessment in a Family Medicine Residency Clinic

Introduction

Sugar-sweetened beverages (SSBs) are a major source of added calories in the American diet, with significant adverse health outcomes. However, intake of SSBs is not commonly assessed in the clinical setting. In some populations with health disparities there is a higher consumption of caloric beverages, contributing to increased cardiometabolic risk. Family medicine residency clinics often provide services for the underserved population, and may encounter additional barriers in nutritional assessment.

Methods

Our study, conducted at a residency clinic in Omaha, Nebraska, utilized the abbreviated Beverage Intake Questionnaire 15 (BEVQ-15). We surveyed 310 patients over a 3-month period.

Results

Consumption of SSBs in our sample was significantly higher than that of the nonclinic population of Nebraska (P<0.001). Fifty-six percent of resident clinic respondents reportedly consumed at least one SSB daily, resulting in an average intake of 244 kilocalories. Intake was significantly higher in males, younger patients, those with lower socioeconomic status, and Latinos. While the majority of the study population was obese, there was no direct correlation between weight and SSB intake. The survey required less than 3 minutes to complete. Future interventions may focus on reduction of SSB intake and promotion of water consumption.

Conclusions

Assessment of SSB intake in a family medicine residency clinic can be easily conducted, providing opportunities for clinical providers to suggest patient-specific modifiable behaviors. As the obesity epidemic continues to progress, point-of-care intervention to reduce SSB consumption may help reduce cardiometabolic risk and improve health outcomes.

Nutrition Education in Internal Medicine Residency Programs and Predictors of Residents' Dietary Counseling Practices

BACKGROUND

Although physicians are expected to provide dietary counseling for patients with cardiovascular (CV) risk factors such as hypertension, hyperlipidemia, diabetes, and obesity, nutrition education in graduate medical education remains limited. Few studies have recently examined nutrition education and dietary counseling practices in Internal Medicine (IM) residency training.

OBJECTIVES

To conduct a contemporary assessment of outpatient nutrition education in IM residency programs in the United States, identify predictors of residents' dietary counseling practices for CV risk factors, and identify barriers for educators in providing nutrition education and barriers for residents in counseling patients.

DESIGN

Cross-sectional anonymous surveys were completed by IM program directors (PDs) and residents throughout the United States. Linear regression was used to examine the association between the amount of nutrition education received and the number of instruction methods used by the residents and frequency of residents' dietary counseling for patients with CV risk factors.

KEY RESULTS

A total of 40 educators (PDs and ambulatory/primary care PDs) and 133 residents across the United States responded to the survey. About 61% of residents reported having very little or no training in nutrition. Nutrition education in residency, both the amount of education (β = 0.20, P = .05) and the number of instruction methods used (β = 0.26, P = .02), predicted frequency of residents' dietary counseling practices independent of nutrition education in medical school, which was also significantly associated with counseling (β = 0.20, P = .03). Residents' total fruit and vegetable intake likewise predicted frequency of counseling (β = 0.24, P < .001). Low perceived faculty expertise was a major barrier for educators and was associated with lower level of provided nutrition education (r = -.33, P = .04). Low resident and low perceived clinic preceptors' interests in nutrition were also associated with lower frequency of residents' dietary counseling (r = -.19, P = .04; r = -.18, P = .05).

CONCLUSIONS

The provision of nutrition education in IM residency programs and IM residents' dietary counseling for patients need to be systematically assessed nationally. This study's preliminary findings suggest that multimodal nutrition education in IM residency and better resident dietary habits are associated with higher frequency of dietary counseling for patients. Lack of faculty expertise and low faculty and resident interests in patient counseling need to be addressed perhaps by mandating nutrition education in graduate and continuing medical education.

The Domains of Human Nutrition: The Importance of Nutrition Education in Academia and Medical Schools

Human nutrition encompasses an extremely broad range of medical, social, commercial, and ethical domains and thus represents a wide, interdisciplinary scientific and cultural discipline. The high prevalence of both disease-related malnutrition and overweight/obesity represents an important risk factor for disease burden and mortality worldwide. It is the opinion of Federation of the Italian Nutrition Societies (FeSIN) that these two sides of the same coin, with their sociocultural background, are related to a low "nutritional culture" secondary, at least in part, to an insufficient academic training for health-care professionals (HCPs). Therefore, FeSIN created a study group, composed of delegates of all the federated societies and representing the different HCPs involved in human nutrition, with the aim of identifying and defining the domains of human nutrition in the attempt to more clearly define the cultural identity of human nutrition in an academically and professionally oriented perspective and to report the conclusions in a position paper. Three main domains of human nutrition, namely, basic nutrition, applied nutrition, and clinical nutrition, were identified. FeSIN has examined the areas of knowledge pertinent to human nutrition. Thirty-two items were identified, attributed to one or more of the three domains and ranked considering their diverse importance for academic training in the different domains of human nutrition. Finally, the study group proposed the attribution of the different areas of knowledge to the degree courses where training in human nutrition is deemed necessary (e.g., schools of medicine, biology, nursing, etc.). It is conceivable that, in the near future, a better integration of the professionals involved in the field of human nutrition will eventually occur based on the progressive consolidation of knowledge, competence, and skills in the different areas and domains of this discipline.

Ecologic Momentary Assessment: Perspectives on Applications and Opportunities in Research and Practice Regarding Nutrition Behaviors

Retrospective self-reported data have limitations, making it important to evaluate alternative forms of measurement for nutrition behaviors. Ecological momentary assessment (EMA) attempts to overcome the challenges of recalled data with real-time data collection in a subject's natural environment, often leveraging technology. This perspective piece 1) introduces the concepts and terminology of EMA, 2) provides an overview of the methodological and analytical considerations, 3) gives examples of past research using EMA, and 4) suggests new opportunities (including combining assessment and intervention) and limitations (including the need for technology) for the application of EMA to research and practice regarding nutrition behaviors.

Factors Underlying Variation in Receipt of Physician Advice on Diet and Exercise: Applications of the Behavioral Model of Health Care Utilization

Purpose.

To identify factors associated with receipt of physician advice on diet and exercise, including patient sociodemographic characteristics, health-related needs, and health care access, using Andersen's model of health care utilization.

Design.

A cross-sectional analysis was performed using data from the 2000 National Health Interview Survey (NHIS).

Setting.

NHIS data were collected through personal household interviews by Census interviewers. The overall response rate for the 2000 NHIS adult sample was 82.6%.

Subjects.

Subjects were a representative sample of the American civilian, noninstitutionalized population aged 18 and older. After eliminating missing data and respondents who reported they did not see a doctor in the past 12 months, sample sizes for physician advice on diet and exercise were n = 26,255 and n = 26,158, respectively.

Measures.

Using the 2000 NHIS, the prevalence of receipt of physician advice on diet and exercise was assessed. Multiple logistic regression analyses were performed to examine the associations between receipt of physician advice on diet and exercise and potential predictors, adjusting for all covariates.

Results.

By self-report, 21.3% and 24.5% of respondents received physician advice on diet and exercise, respectively. Being middle-aged (adjusted odds ratio [AOR] = 1.14, 95% confidence interval [CI], 1.0–1.29 for diet; AOR = 1.55, 95% CI = 1.33–1.79 for exercise) and having a baccalaureate degree or higher (AOR = 1.78, 95% CI = 1.52–2.08 for diet; AOR = 1.75, 95% CI = 1.47–2.07) were associated with a higher likelihood of receiving physician advice on diet and exercise. African-Americans (AOR = .78, 95% CI = .67–.92) and foreign-born immigrants (AOR = .57, 95% CI = .38–.86) were less likely to receive physician advice on exercise. The prevalence of physician advice was higher for persons who chose hospital outpatient departments as a usual source for care (AOR = 2.36, 95% CI = 1.66–3.36 for diet; AOR = 2.39, 95% CI = 1.68–3.4 for exercise) than for adults with other types of usual care sites. Poorer self-rated health status (AOR = 5.2, 95% CI = 4.12–6.57 for diet; AOR = 2.63, 95% CI = 2.04–3.38 for exercise) and obesity (AOR = 2.32, 95% CI = 2.02–2.66 for diet; AOR = 3.01, 95% CI = 2.46–3.69 for exercise) was positively associated with the likelihood of receiving physician advice on diet and exercise.

Conclusions.

Effective strategies to increase receipt of physician advice should include efforts to improve access to regular source of care and patient-physician communication. Sociodemographic factors remain independent and important predictors of who obtains such advice.

Trends and disparities in the prevalence of physicians' counseling on diet and nutrition among the U.S. adult population, 2000-2011

BACKGROUND

Although healthy eating plays a crucial role in addressing the obesity and chronic disease epidemics, a few Americans have diets that meet dietary guidelines. Because physicians-delivered counseling is a strong predictor for behavioral modification among patients, the Healthy People Objectives have emphasized diet counseling since 2000. However, research on impact of physicians' counseling over time on a national level has been limited.

METHODS

We used data from the 2000 and 2011 National Health Interview Surveys to apply a logistic regression model to identify predictors of physicians' counseling and examine any changes in disparities over a decade.

RESULTS

In 2000, only 23.7% of our national sample had received dietary counseling, it increased to 32.6% in 2011. Hispanics were less likely than Whites to receive advice on diet in 2000 (adjusted odds ratio [AOR]=0.74, 95% confidence interval [CI]=0.62-0.88). By 2011, Hispanics 18% (AOR=1.18, CI=1.09-1.28) and Blacks were 42% (AOR=1.42, CI=1.32-1.54) more likely to receive advice from their physicians on diet than Whites. In both years, men were significantly less likely than women to receive counseling. The uninsured patients were increasingly less likely than insured patients in receiving diet counseling, being 60% less likely in 2011 (AOR=0.40, CI=0.37-0.40). Obese patients were substantially (88% in 2000 to 290% in 2011) more likely to receive counseling than normal-weight patients.

CONCLUSIONS

The overall prevalence of physicians' counseling on diet increased moderately between 2000 and 2011. However, substantial disparities in dietary counseling related to access to care and gender continue to exist.

Association of intimate partner violence and health-care provider-identified obesity

The association of physical and nonphysical intimate partner violence (IPV) with obesity was examined. Women (N = 1,179) were surveyed regarding demographics, obesity, and IPV exposure using humiliate-afraid-rape-kick (HARK), an IPV screening tool. A three-level lifetime IPV exposure variable measured physical, nonphysical or no IPV. Health-care provider-identified obesity was defined if participants were told by a medical provider within the past 5 years that they were obese. Bivariate analyses examined obesity by IPV and demographics. Multivariable logistic regression assessed odds of obesity by IPV type, adjusting for age, race/ethnicity, education, and marital status. Among participants, 44% reported lifetime IPV (25% physical, 19% nonphysical), and 24% reported health-care provider-identified obesity. In unadjusted analyses, obesity was more prevalent among women exposed to physical IPV (30%) and nonphysical IPV (27%), compared to women without IPV (20%, p = .002). In multivariable models, women reporting physical IPV had 1.67 times greater odds of obesity (95% confidence interval [CI] 1.20, 2.33), and women reporting nonphysical IPV had 1.46 times greater odds of obesity (95% CI 1.01, 2.10), compared to women reporting no exposure. This study extends prior data by showing, not only an association between physical IPV and obesity, but also an association between obesity and nonphysical IPV.

Interprofessional dietary assessment practices in primary care: A mixed-methods study

Patients in primary care (PC) are often counselled on diet, and assessment of current food intake is a necessary prerequisite for individualized nutrition care. This sequential mixed-methods study explored current diet assessment (DA) practices in team-based PC in Ontario, Canada, with interdisciplinary focus groups (FGs) followed by a web-based survey. Eleven FGs (n = 50) discussed key patient groups and health conditions requiring DA, as well as facilitators and barriers to accurate DA. Interpretative analysis revealed three themes: DA as a common activity that differed by health profession, communication of DA results within the team, and nutrition care as a collaborative team activity. A total of 191 providers from 73 Family Health Teams completed the web-based survey, and confirmed that many providers are frequently doing DA and that methods vary by discipline. Most providers conducted DAs every day or almost every day. As expected, dietitians used more formal and detailed methods to assess diet than other disciplines, who were more likely to ask a few pointed questions. These baseline data provide information on the range of current DA practices in team-based PC that can inform development of new, more accurate approaches that may improve counselling effectiveness.

A Survey of Medical Students’ Use of Nutrition Resources and Perceived Competency in Providing Basic Nutrition Education

Purpose. The aims of this study were to assess where medical students obtain their nutrition information and their self-perceived level of competency in providing basic nutrition education to patients. Methods. A survey was distributed to all first through fourth year medical students at Case Western Reserve University (n=657). For statistical analysis, data was expressed as percentages of total responses and binomial regression was used to answer the study hypotheses. Results. The survey response rate was 47%. Forty-two percent of respondents selected a majority of professional nutrition resources (n=132) as their most commonly used nutrition resources, 38% selected a majority of consumer resources (n=119), and 20% selected “I do not use nutrition resources” (n=61). The most popular nutrition resource selected was consumer websites. Seventy percent of respondents reported feeling competent in their ability to provide basic nutrition education to patients (n=219). Conclusion. Medical students seem to feel competent in their ability to give basic nutrition education to patients, but they may be obtaining nutrition information from unreliable consumer-based resources. To help increase the provision of sound nutritional guidance, medical students should be taught to use reliable nutrition resources, as well as the value of referring patients to registered dietitians.

Does pragmatically structured outpatient dietary counselling reduce sodium intake in hypertensive patients? Study protocol for a randomized controlled trial

Background

Hypertension is highly prevalent among adults, and is the most important modifiable risk factor for cardiovascular events, in particular stroke. Decreasing sodium intake has the potential to prevent or delay the development of hypertension and improve blood pressure control, independently of blood pressure lowering drugs, among hypertensive patients. Despite guidelines recommending a low sodium diet, especially for hypertensive individuals, sodium intake remains higher than recommended. A recent systematic review indicated that the efficacious counselling methods described in published trials are not suitable for hypertension management by primary care providers in Canada in the present form. The primary reason for the lack of feasibility is that interventions for sodium restriction in these trials was not limited to counselling, but included provision of food, prepared meals, or intensive inpatient training sessions.

Methods/design

This is a parallel, randomized, controlled, open-label trial with blinded endpoints. Inclusion criteria are adult patients with hypertension with high dietary sodium intake (defined as ≥100 mmol/day). The control arm will receive usual care, and the intervention arm will receive usual care and an additional structured counselling session by a registered dietitian, with four follow-up telephone support sessions over four weeks. The two primary outcomes are change in sodium intake from baseline, as measured by a change in 24-hour urinary sodium measurements at four weeks and one year. Secondary outcomes include change in blood pressure (as measured by 24-hour ambulatory monitoring), change in 24-hour urinary potassium, and change in body weight at the same time points.

Discussion

Though decreasing sodium intake has been reported to be efficacious in lowering blood pressure, there exists a gap in the evidence for an effective intervention that could be easily translated into clinical practice. If successful, our intervention would be suitable for outpatient programs such as hypertension clinics or interprofessional family practices (family health teams). A negative, or partially negative (positive effect at four weeks with attrition by 12 months) trial outcome also has significant implications for healthcare delivery and use of resources.

Trial registration

The trial was registered with Clinicaltrials.gov (identifier: NCT02283697) on 2 November 2014.

What is the feasibility of implementing effective sodium reduction strategies to treat hypertension in primary care settings? A systematic review

OBJECTIVE

To evaluate whether efficacious counseling methods on sodium restriction can be successfully incorporated into primary care models for the management of hypertension.

METHODS

We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects and Health Technology Assessment to identify randomized controlled trials of dietary counseling for salt intake reduction that reported significant reduction in 24-h urinary sodium and blood pressure levels among adults with untreated hypertension. Data extraction and assessment of reproducibility and feasibility were done in duplicate and any disagreements were resolved by consensus.

RESULTS

Six trials were included for assessment of methods as they were efficacious in reducing sodium intake (24-h urinary sodium excretion) by 73 to 93 mmol/day (intervention) vs. 3.2 to 12.5 mmol/day (control). This was paralleled with a reduction in blood pressure (-4 to -27  mmHg) between groups. In four of the six trials, the methods were described in sufficient detail to be reproducible, but in none of these trials were the 'counseling methods' feasible for application in primary care settings. Apart from multiple sessions of counseling, the reported interventions were supplemented with provision of prepared food, community cooking classes, and intensive inpatient training sessions.

CONCLUSION

Despite the availability of efficacious counseling methods for the reduction of sodium intake among newly diagnosed hypertensive patients (feasible within a clinical trial setting), none of these methods, in their present form, are suitable for incorporation into existing primary care settings in countries such as Canada, United States, and UK.

Quality of weight-loss counseling by Dutch practice nurses in primary care: an observational study

BACKGROUND/OBJECTIVE

To assess the quality of weight-loss counseling provided by Dutch primary care practice nurses (PNs) to overweight and obese patients including both PNs' compliance with the Five A's Model for behavioral counseling in primary care, and the use of different communication styles. In addition, relationships between PN/patient characteristics (including Five A's) and communication styles will be examined.

SUBJECTS/METHODS

In this observational study, 100 videotaped real-life consultations, collected in 2010/2011, were viewed using an observational checklist. Selection of consultations was based on PNs' registration of patient's complaint. The quality of weight-loss counseling was assessed by the Five A's Model (sequence of evidence-based practice behaviors that are effective for helping patients to change health behaviors) and by PNs' communication styles. Moreover, several PN and patient characteristics were registered. Descriptive statistics and logistic regression analysis were conducted with significance set at P<0.05.

RESULTS

PNs most frequently arranged follow-up, assessed the risk and current behavior and advised. However, they rarely assisted in addressing barriers and securing support. For weight or physical activity, most PNs used a motivational communication style. In discussions of nutrition, they mostly used an informational communication style. Moreover, PNs used a combination of communication styles. PN characteristics, including their behavior concerning the Five A's, were stronger related to communication styles than patient characteristics.

CONCLUSIONS

PNs reasonably complied with the Five A's Model. The quality of PNs' weight-loss counseling might be increased by routinely providing assistance in addressing barriers and securing support, and routinely reaching agreement with collaboratively set goals.

The content of diet and physical activity consultations with older adults in primary care

OBJECTIVE

Despite numerous benefits of consuming a healthy diet and receiving regular physical activity, engagement in these behaviors is suboptimal. Since primary care visits are influential in promoting healthy behaviors, we sought to describe whether and how diet and physical activity are discussed during older adults' primary care visits.

METHODS

115 adults aged 65 and older consented to have their routine primary care visits recorded. Audio-recorded visits were transcribed and diet and physical activity content was coded and analyzed.

RESULTS

Diet and physical activity were discussed in the majority of visits. When these discussions occurred, they lasted an average of a minute and a half. Encouragement and broad discussion of benefits of improved diet and physical activity levels were the common type of exchange. Discussions rarely involved patient behavioral self-assessments, patient questions, or providers' recommendations.

CONCLUSIONS

The majority of patient visits include discussion of diet and physical activity, but these discussions are often brief and rarely include recommendations.

PRACTICE IMPLICATIONS

Providers may want to consider ways to expand their lifestyle behavior discussions to increase patient involvement and provide more detailed, actionable recommendations for behavior change. Additionally, given time constraints, a wider array of approaches to lifestyle counseling may be necessary.

Dietary counselling for cardiovascular disease prevention in primary care settings: results from a German physician survey

BACKGROUND

Primary care physicians (PCPs) play an important role in the promotion of healthy dietary behaviour. However, little is known about the practice of and factors associated with the provision of dietary counselling in primary health care in Germany.

OBJECTIVES

To explore the attitudes towards and factors associated with the routine provision of dietary counselling in Germany using data from the nationwide, representative sample of the Physician Survey on Cardiovascular Disease Prevention.

METHODS

A total of 4074 randomly selected PCPs (response rate: 33.9%) provided data on dietary counselling for prevention of cardiovascular disease (CVD) based on the 5 A's (Assess, Advise, Agree, Assist, Arrange), attitudes towards dietary counselling and patients' and practice characteristics.

RESULTS

While the majority of PCPs (86%) reported having high levels of competence in providing dietary advice, only 49% felt they had been successful in counselling their patients on nutrition. PCPs routinely asked (68%) and advised patients to change their dietary habits more frequently (77%) compared to other counselling techniques based on the 5 A's. Female physicians and those with a higher percentage of privately insured patients and patients at higher risk of CVD were more likely to use the 5 A's to routinely counsel their patients on nutrition.

CONCLUSIONS

The data showed high levels of involvement by German PCPs in CVD prevention and dietary counselling. The rather low perceived success of dietary intervention and differences with respect to patients' health insurance status indicate a need to address both communication skills in medical training and appropriate reimbursement of preventive services.

Direct observation of weight counselling in primary care: alignment with clinical guidelines

Primary care physicians provide care to a disproportionate number of overweight and obese patients and are uniquely positioned to help patients manage their weight in the context of a continuity relationship. The US National Heart, Lung and Blood Institute (NHLBI) developed evidence-based guidelines for the effective and efficient care of overweight/obese patients, but little is known about the use of these guidelines in practice. To determine the content of weight discussions and assess the elements of the NHLBI guidelines that were accomplished, office visits of 544 adult, overweight/obese patients to 28 primary care physicians were observed and audio recorded. Associations between type of weight management discussion and patient, physician and visit characteristics were examined. Fifty per cent (n = 270) of visits included weight discussions; 47% and 38% included use of at least one NHLBI assessment or treatment element during discussions about weight, respectively. Only 35% (n = 193) of discussions included an assessment and treatment strategy; none included all NHLBI-recommended elements. Overall, adherence to guidelines was poor, particularly with regard to reporting body mass index to the patient, measuring waist circumference and setting realistic weight loss goals. Weight discussions did not clearly vary by the patient, physician or visit characteristics examined. These findings suggest opportunities to develop and further tailor resources for improved physician training in patient weight management communication and treatment techniques that are both consistent with current standards for effective, evidence-based care and efficient enough for routine use during busy primary care visits.

Factors associated with consulting a dietitian for diabetes management: a cross-sectional study

BACKGROUND

Type 2 Diabetes (T2D) has reached epidemic levels in the Middle East region. Despite evidence that it improves health outcomes and saves health costs, dietary counseling for T2D remains grossly under-investigated in this region. The aim of this study was to assess the frequency and determinants of use of dietary counseling services by T2D patients in Lebanon and recommend corrective measures that may guide the planning, organization and delivery of care for chronic diseases in general and diabetes care in particular.

METHODS

A non-experimental cross-sectional design was utilized to survey outpatients with T2D in two major health centers in Lebanon. Patients diagnosed with T2D were invited to complete a questionnaire consisting of five sections: socio-demographic characteristics, disease attributes, patients' perceptions regarding T2D management, practice of lifestyle modifications, and referral by a physician to a dietitian. The outcome of interest was the use of dietary counseling services by T2D patients at least once since their diagnosis. Descriptive statistics and logistic regression analyses were used to evaluate the frequency and determinants of dietary counseling services utilization.

RESULTS

A total of 332 T2D patients completed the questionnaire (response rate 94.6%). Although 75% of study participants believed that dietitians can assist them in changing their dietary habits, only 38% had consulted with a dietitian. Among study participants, only 34% were referred to a dietitian by their physician. The main determinants of the use of dietary counseling services were referral by a physician (OR: 112.25; 95% CI = 42.74-294.84), the presence of outpatient social or private health insurance (OR: 5.86; 95% CI = 2.40-14.25) and the belief that a dietitian can assist in changing dietary habits (OR: 3.74; 95% CI = 1.33-10.54).

CONCLUSIONS

The findings of this study show suboptimal use of dietary counseling services by T2D patients in Lebanon. Key determinants were physicians' referral, financial support for outpatient care, and patients' belief in the usefulness of dietary counseling. Suggested interventions entail enhancing the planning and organization of care through inter-professional collaboration between physicians and dietitians; promoting public financing for high quality outpatient care that includes dietary counseling; and promoting the value of dietary counseling and improving the public image of dietitians.

Advice for salt, sugar and fat intake habits among adults: a national-based study

INTRODUCTION : A healthy diet is recognized as an important strategy for promoting health as an essential part of non-pharmacological therapy of various health problems. OBJECTIVE : To analyze the reported advice for the intake of salt, sugar and fat for the Brazilian adults living in urban areas. METHODOLOGY : National-based cross-sectional study with 12,402 adults interviewed in 100 Brazilian cities. RESULTS : The most prevalent advice was to low fat intake (38%), followed by the advice to low salt and sugar intake (36%) and sugar (29%). The percentage of receiving different advice was similar and more common among women, older people, those with a partner, higher economic class, former smokers, active and in person with physician diagnoses of hypertension, diabetes and overweight. People with white skin color received more advice to eat healthy food, except for the orientation to low salt intake. CONCLUSION : The results show a low prevalence of advice, which configures a missed opportunity to prevent health problems. Although dietary counseling should not be understood only as the transmission of advice regarding some nutrients, it is important to develop actions in order to qualify services and health professionals, allowing the population to have access to qualified information about the benefits of having healthy lifestyles.

Examining the content of weight, nutrition and physical activity advices provided by Dutch practice nurses in primary care: analysis of videotaped consultations

BACKGROUND/OBJECTIVE

To examine the content of Dutch practice nurses' (PNs') advices about weight, nutrition and physical activity to overweight and obese patients.

SUBJECTS/METHODS

A 100 videotaped real-life PN consultations (The Netherlands, 2010/2011) with overweight or obese patients were selected. An observational checklist was developed to assess frequency and content. Personalization of advices was scored, as also the guidelines on which PNs based their advices. Content analysis was used to identify different categories of advices.

RESULTS

About one quarter of advices concerned weight, over two-thirds nutrition and one-third physical activity. Lose weight, eat less fat and be more physically active in general were the main categories for each type of advice. Despite high clarity of advices, lower scores were found for specificity and personalization. Very few nutrition advices were provided in combination with physical activity advices.

CONCLUSIONS

Weight advices often related to the patient's complaint. PNs seldom set a concrete weight goal. Although benefits of physical activity were discussed, often no practical advices were provided about how to achieve this. Integrated lifestyle advice was not common: advices about nutrition and physical activity were fragmented throughout the consultation. Obesity prevention needs more emphasis in PNs' educational programs.

What are key factors influencing malnutrition screening in community-dwelling elderly populations by general practitioners? A large cross-sectional survey in two areas of France

BACKGROUND/OBJECTIVES

Malnutrition is associated with a high morbi-mortality in elderly populations and their institutionalization at an early stage. The incidence is well known despite being often under-diagnosed in primary care. General practitioners (GPs) have a key role in home care. What are the factors affecting malnutrition-screening implementation by French GPs?

SUBJECTS/METHODS

We conducted a cross-sectional survey in two areas in the southeast of France (Savoie and Isère). In May 2008, an anonymized survey was sent by e-mail and/or post to all GPs with a large clinical practice. Two months later, reminder letters were sent. Potential barriers were measured by dichotomous scale. On GPs' characteristics (socio-demographic, medical training, geriatric practice and knowledge), multiple regression logistic was performed to identify others factors affecting malnutrition screening.

RESULTS

In all, 493 GPs (26.85%) answered and 72.2% felt that malnutrition screening was useful although only 26.6% implemented it each year and 11.9% every 2-5 years. The main barriers to the implementation were patient selection (60.4%) and forgetting to screen (26.6%). Minor barriers were lack of knowledge (19.5%) or time (15%). New factors were identified: unsuitable working conditions (19.1%), insufficient motivation (6.8%) or technical support (7.2%). The quality of malnutrition information received was found to be the only promoter of annual screening (odds ratio=1.44 (1.087-1.919); P=0.011).

CONCLUSIONS

This survey is the first in France to reveal GPs' factors affecting malnutrition implementation. New obstacles were identified in this survey. The hope of implementing regular malnutrition screening by GPs seems to lie with the quality of malnutrition information received.

Nutrition and physical activity guidance practices in general practice: a critical review

OBJECTIVE

The aim of this critical review is to provide insight into the main outcomes of research on communication about nutrition and/or physical activity between GPs and patients for prevention or treatment of overweight and obesity.

METHODS

Relevant studies were identified by a computerized search of multiple electronic databases (MEDLINE, PsycINFO) for all available papers between 1 January 1995 and 1 January 2012. In addition, two independent reviewers judged all studies on ten quality criteria.

RESULTS

In total, 41 studies were retrieved. More studies were found about the guidance of obese patients than of overweight patients. The most common weight guidance practice was discussion of weight. The range of communication strategies for nutrition showed to be more diverse than for physical activity. Twelve studies were considered as high-quality studies, 18 were having medium quality, and 11 were seen as low quality.

CONCLUSION

We reflected on the fact that the content of advice about nutrition and physical activity was quite general. GPs' provision of combined lifestyle advice to overweight and obese patients seems to be rather low.

PRACTICE IMPLICATIONS

Observational research is needed to unravel the quality of the advice given by GPs to overweight and obese patients.

Missed opportunities for providing low-fat dietary advice to people with diabetes

Introduction

Because cardiovascular disease is closely linked to diabetes, national guidelines recommend low-fat dietary advice for patients who have cardiovascular disease or are at risk for diabetes. The prevalence of receiving such advice is not known. We assessed the lifetime prevalence rates of receiving low-fat dietary advice from a health professional and the relationship between having diabetes or risk factors for diabetes and receiving low-fat dietary advice.

Methods

From 2002 through 2009, 188,006 adults answered the following question in the Medical Expenditure Panel Survey: “Has a doctor or other health professional ever advised you to eat fewer high-fat or high-cholesterol foods?” We assessed the association between receiving advice and the following predictors: a diabetes diagnosis, 7 single risk factors for type 2 diabetes, and total number of risk factors.

Results

Among respondents without diabetes or risk factors for diabetes, 7.4% received low-fat dietary advice; 70.6% of respondents with diabetes received advice. Respondents with diabetes were almost twice as likely to receive advice as respondents without diabetes or its risk factors. As the number of risk factors increased, the likelihood of receiving low-fat dietary advice increased. Although unadjusted advice rates increased during the study period, the likelihood of receiving advice decreased.

Conclusion

Although most participants with diabetes received low-fat dietary advice, almost one-third did not. Low-fat dietary advice was more closely associated with the total number of diabetes risk factors than the presence of diabetes. Increasing rates of diabetes and diabetes risk factors are outpacing increases in provision of low-fat dietary advice.

Determinants of Dutch general practitioners' nutrition and physical activity guidance practices

OBJECTIVE

General practitioners (GP) are uniquely placed to guide their patients on nutrition and physical activity. The aims of the present study were to assess: (i) the extent to which GP guide on nutrition and physical activity; (ii) the determinants that cause GP to give guidance on nutrition and physical activity; and (iii) the extent to which these guidance practices have the same determinants.

DESIGN

Cross-sectional study, mail questionnaire.

SETTING

Dutch general practice.

SUBJECTS

Four hundred and seventy-two GP in practice for 5–30 years.

RESULTS

Our study showed that the majority of GP had similar practices for both nutrition and physical activity guidance. Fair associations were found between nutrition and physical activity guidance practices. More than half of the explained variance in the models of physical activity guidance practices was improved by the inclusion of nutrition guidance practices in the models. Moreover, GP reported higher frequencies of physical activity guidance practices than nutrition guidance practices. Nutrition guidance practices predicted the same physical activity guidance practices.

CONCLUSIONS

The majority of GP had similar practices for nutrition and physical activity guidance. GP were more inclined to guide their patients on physical activity than on nutrition. Self-efficacy was found to be a determinant in most models for guidance practices. Guidance practices proved to be a mix of prevention and treatment components. Consequently, we advise raising the selfefficacy of GP by training in medical school and in continuing medical education. We also recommend the combination of both nutrition and physical activity guidance in general practice.

Behavioral Counseling for Cardiovascular Disease Prevention in Primary Care Settings

Cardiovascular disease carries a substantial public health burden. Physician advice on modifying behavioral risk factors is effective, yet the practice of and factors associated with behavioral counseling in primary care have not been systematically investigated. The authors conducted a systematic review that identified 18 studies providing data on 6,338 physicians. The provision of preventive services differed by patients’ individual risk. Physicians’ counseling on smoking cessation was most commonly reported. The proportions of physicians counseling about nutrition and physical activity were notably lower and few physicians took further action by using more intensive counseling approaches. As studies were mainly based on self-reports, current delivery of preventive services may be overestimated. There is a need to increase the frequency of behavioral counseling in primary care settings, particularly for nutrition and physical activity, and to emphasize that counseling may also benefit individuals without cardiovascular disease risk factors.

Results of the Heart Healthy and Ethnically Relevant Lifestyle trial: a cardiovascular risk reduction intervention for African American women attending community health centers

OBJECTIVES

We evaluated a theory-based lifestyle intervention targeting physical activity and dietary fat intake among African American women at high risk for cardiovascular disease.

METHODS

The Heart Healthy and Ethnically Relevant Lifestyle trial (2005-2008) randomly assigned 266 low-income African American women aged 35 years and older who were patients of South Carolina community health care centers into comprehensive or standard care interventions. Comprehensive participants received standard care (stage-matched provider counseling and assisted goal setting) plus 12 months of telephone counseling and tailored newsletters. Primary outcomes were 6- and 12-month self-reported physical activity and dietary fat intake.

RESULTS

Comprehensive participants were more likely than were standard care participants to decrease total physical activity (odds ratio [OR] = 3.13; 95% confidence interval [CI] = 1.18, 8.25) and increase leisure-time physical activity (OR = 3.82; 95% CI = 1.41, 10.3) at 6 months (no 12-month differences). Mean reductions in Dietary Risk Assessment score occurred in both groups but were greater among comprehensive participants than among standard care participants (6 months, -8.50 vs -5.34; 12 months, -7.16 vs -3.37; P < .001).

CONCLUSIONS

The comprehensive intervention improved women's leisure-time physical activity and dietary fat intake, highlighting a replicable model to help primary care providers implement lifestyle counseling.

Behaviour-change interventions in primary care: influence on nutrition and on the metabolic syndrome definers

The purpose of this paper was to examine whether interventions influenced patients' (i) consumption of fish; whole grain products; fruits and vegetables; (ii) overall nutrition, that is, the three former as an index; and (iii) clinical outcomes in terms of metabolic syndrome definers. A questionnaire was delivered to adult patients entering the nine health centres on November 2006 (n = 1211). During the year the ward personnel conducted intervention on patients with unhealthy habits. The 12-month follow up was conducted by mailings. Also clinical data of pre- and post-intervention values of metabolic syndrome definers were collected. For the analyses, intervention was divided into brief (≤ 15 min, at most three visits) and extended (> 15 min, more than three visits) intervention. Logistic Regression and manova were used to measure changes in the outcomes. Nutrition-related intervention was conducted on 218 patients (brief intervention n = 179, extended intervention n = 39). In the extended intervention group it was three times more likely to have a positive change in the nutrition index than in the brief intervention group (P = 0.017, confidence interval 1.223-7.773). In conclusion, brief interventions were commonly used in the primary care. However, they were not enough to produce changes in the patients' nutrition or in the clinical outcomes.

Food pattern analysis over time: unhealthful eating trajectories predict obesity

BACKGROUND

Analysis of dietary patterns is prominent in nutrition literatures, yet few studies have taken advantage of multiple repeated measurements to understand the nature of individual-level changes over time in food choice, or the relation between these changes and body mass index (BMI).

OBJECTIVE

To investigate changes in eating patterns at the individual level across three exam periods, and to prospectively examine the relation of eating trajectories to BMI at the cohort level.

DESIGN

The study included 3418 participants at baseline. Clinically measured BMI and dietary intake were assessed during three exam periods between 1991 and 2001 using a validated food frequency questionnaire. An individual's eating trajectory across exam periods was analyzed using sequence analysis, and then used to estimate outcomes of continuous BMI and categorical obesity status. Ordinary least squares regression models with robust standard errors were adjusted for socio-economic and demographic confounders, baseline BMI and baseline eating.

RESULTS

A total of 66.2% (n=1614) of participants change their diet pattern during the study period, 33.8% (n=823) remain stable. After accounting for potential confounders, an unhealthful trajectory is significantly associated with a 0.42 kg m(-2) increase in BMI (confidence interval (CI): 0.1, 0.7). Those with an unhealthful trajectory are 1.79 times more likely to be overweight (relative risk ratio, 95% CI: 1.1, 2.8) and 2.4 times more likely to be obese (relative risk ratio, 95% CI: 1.3, 4.4). Moreover, a number of specific diet transitions between exams are predictive of weight gain or loss.

CONCLUSION

Contextualizing an individual's current eating behaviors with an eye towards diet history may be an important boon in the reduction of obesity. Although it may not be realistic for many people to shift from the least to most healthful diet, results from this study suggest that consistent movement in an overall healthier direction is associated with less weight gain.

General practitioner advice on physical activity: analyses in a cohort of older primary health care patients (getABI)

Background

Although the benefits of physical activity for health and functioning are recognized to extend throughout life, the physical activity level of most older people is insufficient with respect to current guidelines. The primary health care setting may offer an opportunity to influence and to support older people to become physically active on a regular basis. Currently, there is a lack of data concerning general practitioner (GP) advice on physical activity in Germany. Therefore, the aim of this study was to evaluate the rate and characteristics of older patients receiving advice on physical activity from their GP.

Methods

This is a cross-sectional study using data collected at 7 years of follow-up of a prospective cohort study (German epidemiological trial on ankle brachial index, getABI). 6,880 unselected patients aged 65 years and above in the primary health care setting in Germany were followed up since October 2001. During the 7-year follow-up telephone interview, 1,937 patients were asked whether their GP had advised them to get regular physical activity within the preceding 12 months. The interview also included questions on socio-demographic and lifestyle variables, medical conditions, and physical activity. Logistic regression analysis (unadjusted and adjusted for all covariables) was used to examine factors associated with receiving advice. Analyses comprised only complete cases with regard to the analysed variables. Results are expressed as odds ratios (ORs) with 95% confidence intervals (95% CI).

Results

Of the 1,627 analysed patients (median age 77; range 72-93 years; 52.5% women), 534 (32.8%) stated that they had been advised to get regular physical activity. In the adjusted model, those more likely to receive GP advice on physical activity were men (OR [95% CI] 1.34 [1.06-1.70]), patients suffering from pain (1.43 [1.13-1.81]), coronary heart disease and/or myocardial infarction (1.56 [1.21-2.01]), diabetes mellitus (1.79 [1.39-2.30]) or arthritis (1.37 [1.08-1.73]), and patients taking a high (> 5) number of medications (1.41 [1.11-1.80]).

Conclusions

The study revealed a relatively low rate of older primary health care patients receiving GP advice on physical activity. GPs appeared to focus their advice on patients with chronic medical conditions. However, there are likely to be many more patients who would benefit from advice.

Barriers to providing nutrition counseling cited by physicians: a survey of primary care practitioners

In a 1995 pivotal study, Kushner described the attitudes, practice behaviors, and barriers to the delivery of nutrition counseling by primary care physicians. This article recognized nutrition and dietary counseling as key components in the delivery of preventive services by primary care physicians. Kushner called for a multifaceted approach to change physicians' counseling practices. The prevailing belief today is that little has changed. Healthy People 2010 and the U.S. Preventive Task Force identify the need for physicians to address nutrition with patients. The 2010 objective was to increase to 75% the proportion of office visits that included ordering or providing diet counseling for patients with a diagnosis of cardiovascular disease, diabetes, or hypertension. At the midcourse review, the proportion actually declined from 42% to 40%. Primary care physicians continue to believe that providing nutrition counseling is within their realm of responsibility. Yet the gap remains between the proportion of patients who physicians believe would benefit from nutrition counseling and those who receive it from their primary care physician or are referred to dietitians and other healthcare professionals. The barriers cited in recent years continue to be those listed by Kushner: lack of time and compensation and, to a lesser extent, lack of knowledge and resources. The 2010 Surgeon General's Vision for a Healthy and Fit Nation and First Lady Obama's "Let's Move Campaign" spotlight the need for counseling adults and children on diet and physical activity.

CAM: naturopathic dietary interventions for patients with type 2 diabetes

OBJECTIVE

To test feasibility, acceptability, and preliminary effectiveness of a naturopathic dietary intervention in patients with Type 2 diabetes.

METHODS

Prospective observational pilot study evaluating the change in clinical and patient-centered outcome measures following a 12-week individualized and group dietary education program delivered in naturopathic primary care.

RESULTS

HbA1c improved in all participants (n = 12); mean - 0.4% +/- 0.49% SD, (p = 0.02). Adherence to healthful eating increased from 3.5 d/wk to 5.3 d/wk (p = 0.05). Specific nutritional behavior modification included: days/week consuming ≥5 servings of fruit/vegetables (p = 0.01), attention to fat intake (p = 0.05), and -11.3% carbohydrate reduction. Measures of physical activity, self-efficacy and self-management also improved significantly.

CONCLUSION

A naturopathic dietary approach to diabetes appears to be feasible to implement among Type 2 diabetes patients. The intervention may also improve self-management, glycemic control, and have influences in other domains of self-care behaviors. Clinical trials evaluating naturopathic approaches to Type 2 diabetes are warranted.
