Toward a Global Definition of Professionalism for Nutrition and Dietetics Education: A Systematic Review of the Literature

BackgroundProfessionalism of health care practitioners is central to safe and ethical health care, and forms part of the trust that the public places in health care practitioners. Lapses in professionalism in health care present considerable challenges and can have serious consequences and outcomes. Teaching, learning, and assessing professionalism is an important component of nutrition and dietetics education. There is scant peer-reviewed published research related to professionalism in nutrition and dietetics. Providing a definition of professionalism will support progress in curriculum planning and design, teaching, learning and assessment of students, and ongoing professional development of educators and practitioners.ObjectiveThe aim of this study was to conceptualize and define professionalism for the purpose of teaching nutrition and dietetics.DesignThis study included a critical systematic literature review of original research and a targeted and systematic search of national and international dietetics competency standards, exploring the concept and definitions of professionalism in nutrition and dietetics. Competency standards were chosen as an additional focus in the systematic literature search, as they are the key framework documents that guide curriculum development and education standards internationally. Thematic analysis was used to synthesize extracted data and an inductive, interpretivist approach was then applied in conceptualizing a definition of professionalism.ResultsSeven studies and six national and international sets of competency standards were included in the literature review. Four major themes conceptualizing a definition of professionalism for nutrition and dietetics were identified from the integration of the original research and targeted gray literature reviews: 1) personal attributes; 2) interpersonal communication; 3) approach to practice; and 4) commitment to lifelong learning.ConclusionsDefining professionalism for nutrition and dietetics supports progress toward shared understandings, building trust, and assisting in dietetics education and practice. It can be used to support and extend teaching, learning, and assessment of professionalism.     

Academy of Nutrition and Dietetics Benchmarks for Nutrition in Child Care 2011: Are Child-Care Providers across Contexts Meeting Recommendations?

The Academy of Nutrition and Dietetics (Academy) recommends feeding practices for child-care providers to establish nutrition habits in early childhood to prevent obesity. With >12 million US children in child care, little is known about child-care providers’ feeding practices. The purpose of this study was to examine child-care providers’ feeding practices to assess whether providers met the Academy’s benchmarks and whether attainment of benchmarks varied across child-care contexts (Head Start, Child and Adult Care Food Program [CACFP], and non-CACFP). Cross-sectional data was collected in 2011 and 2012 from 118 child-care providers who completed self-administered surveys regarding their feeding practices for 2- to 5-year-old children. χ² tests and analysis of variance were used to determine variation across contexts. Head Start providers sat more frequently with children during meals (P=0.01), ate the same foods as children (P=0.001), and served meals family style (P<0.0001) more often compared with CACFP and non-CACFP providers. Head Start providers (P=0.002), parents (P=0.001), and children (P=0.01) received more nutrition-education opportunities compared with CACFP and non-CACFP. Head Start providers encouraged more balance and variety of foods (P<0.05), offered healthier foods (P<0.05), modeled healthy eating (P<0.001), and taught children about nutrition (P<0.001) compared with CACFP and non-CACFP providers. Providers across all three contexts used significantly more non-internal than internal mealtime verbal comments (P<0.0001). Head Start providers had greater compliance with the Academy’s benchmarks compared with CACFP and non-CACFP providers. Possible reasons for this compliance might be attributed to Head Start nutrition performance standards and increased nutrition-training opportunities for Head Start staff. Head Start programs can serve as a model in implementing the Academy’s benchmarks.

Burns and Nutrition

In adults, burns of 40％ total body surface areas(TBSA)or greater were virtually unsurvivable but a few decades ago.Now, more than half of the adult patients with a 70％ TBSA burn survive. In children, the size of the survivable injury has increased so much that it is now possible to save a child with burns exceeding 95％ TBSA full thickness.The decrease in mortality and morbidity related to major thermal burn injuries noted in the past decade is primarily due to improvements in four major areas.     

What Do Healthcare Providers Know About Nutrition Support? A Survey of the Knowledge,Attitudes, and Practice of Pharmacists and Doctors Toward Nutrition Support in Malaysia

Background and Aims: Malnutrition is one of the health problems that can be prevented by appropriate nutrition care provided by healthcare providers. However, this practice is still lacking possibly because of the providers' inadequate knowledge. The aim of this study was to evaluate the self‐reported knowledge, attitudes, and practices of pharmacists and doctors toward nutrition support in a tertiary care hospital setting. Methods: A validated questionnaire was distributed to all the doctors and pharmacists working in a tertiary hospital in Penang, Malaysia. Seven individuals including academics, general surgeons, and pharmacists performed the face and content validity. The questionnaire was piloted using 24 healthcare providers at a different hospital. Result: Of 400 surveyed, 158 doctors and 72 pharmacists from various grades completed the questionnaire. More doctors (31.6%) than pharmacists (15.3%) reported adequate knowledge to perform patients' nutrition screening. However, in the knowledge assessment, pharmacists had a higher mean score (6.07 ± 1.77) than the doctors did (4.59 ± 1.87; P < .001), and most (70.4%) of them were grouped in the “average” score range. In addition, both pharmacists and doctors have ambivalent attitudes toward nutrition support. Only 31.3% stated that they perform nutrition screening on admission, and half of them performed nutrition assessment during hospitalization. Conclusion: Inappropriate nutrition care might be due to the lack of guidelines and insufficient knowledge among doctors and pharmacists. Special nutrition training and education for both pharmacists and doctors should be established.     

Welcome to the “New” Journal of Nutrition for the Elderly

In 2011, the earliest segment of the baby boom generation turned 65 years of age. This event marks the beginning of a new phase of growth of the older adult population in the United States and is in line with what is referred to worldwide as “population aging.” By 2030, older adults will comprise 20% of the U.S. population. With the impending increase in the older adult population, the United States is unprepared to handle the accompanying social and economic impact of growing rates of age-related diseases such as diabetes, hypertension, and cardiovascular disease. These diseases have nutritional determinants and, as such, they signify the need for effective preventive nutrition initiatives to address population aging in the United States. Comparatively, the European Union (EU) is projected to reach an older adult population of 24% by 2030. In this special article we evaluate nutrition initiatives for older adults in the United States and also examine nutrition initiatives in the European Union in search of an ideal model. However, we found that available data for EU initiatives targeted at population aging were limited. We conclude by offering the proposal of a physician-based model that establishes the primary care physician as the initiator of nutrition screening, education, referrals, and follow-up for the older adult population in the United States as a long-term goal. Apropos of the immediate future, we consider barriers that underscore the establishment of a physician-based model and suggest objectives that are attainable. Although the data are limited for the European Union, this model may serve to guide management of chronic diseases with a nutritional component in economies similar to the United States worldwide.     

Nutrition—an essential component of health and health care.

Nutrition and medicine interface in a variety of ways and combine to serve as a dynamic force in health as well as in disease. A conceptual understanding of this interrelationship is critical to the continued and effective development of clinical nutrition in medical education. The physician may play an important role in critical-care medicine, long-term health care, research, education, and preventive medicine. While there is great potential for the physician to impact on nutrition status in both health and disease, there is clear evidence that greater emphasis needs to be placed on providing adequate nutrition training for every physician.     

Prevalence and Associated Factors of Tinnitus: Data From the Korean National Health and Nutrition Examination Survey 2009–2011

Background

Tinnitus is a common condition and frequently can be annoying to affected individuals. We investigated the prevalence and associated factors for tinnitus in South Korea using the data from the Korea National Health and Nutrition Examination Surveys (KNHANES) during 2009–2011.

Methods

KNHANES is a cross-sectional survey of the civilian, non-institutionalized population of South Korea (n = 21 893). A field survey team that included an otolaryngologist moved with a mobile examination unit and performed interviews and physical examinations.

Results

Among the population over 12 years of age, the prevalence of any tinnitus was 19.7% (95% CI 18.8%–20.6%). Tinnitus was more prevalent in women, and the prevalence rate increased with age (P < 0.001). Among those with any tinnitus, 29.3% (95% CI 27.3%–31.3%) experienced annoying tinnitus that affected daily life. Annoying tinnitus also increased with age (P < 0.001), but no sex difference was demonstrated (P = 0.25). In participants aged 40 years or older, age, quality of life, depressive mood, hearing loss, feeling of dizziness, and rhinitis were associated with any tinnitus (P < 0.05). Age, hearing loss, history of cardiovascular disease, and stress were associated with annoying tinnitus (P < 0.05).

Conclusions

Tinnitus is a common condition, and a large population suffers from annoying tinnitus in South Korea. Public understanding of associated factors might contribute to better management of tinnitus.Key words: tinnitus, epidemiology, associated factor, South Korea     

Participation in the Supplemental Nutrition Assistance Program and Dietary Behaviors: Role of Community Food Environment

BackgroundThe United States Department of Agriculture’s Supplemental Nutrition Assistance Program (SNAP) is the country’s largest nutrition assistance program for low-income populations. Although SNAP has been shown to reduce food insecurity, research findings on the diet quality of program participants are inconsistent.ObjectiveThis study evaluated whether the community food environment is a potential moderator of the association between SNAP participation and eating behaviors.DesignThis cross-sectional study used participant data from a telephone survey of 2,211 households in four cities in New Jersey. Data were collected from two cross-sectional panels from 2009 to 2010 and 2014. Food outlet data were purchased from commercial sources and classified as supermarkets, small grocery stores, convenience stores, or limited service restaurants.Participants/settingAnalysis is limited to 983 respondents (588 SNAP participants) with household incomes below 130% of the federal poverty level.Main outcome measuresEating behaviors were assessed as frequency of consumption of fruit, vegetables, salad, and sugar-sweetened beverages.Statistical analyses performedInteraction and stratified analyses using gamma regression determined the differences in the association between SNAP participation and eating behaviors by the presence or absence of food outlets adjusted for covariates.ResultsSNAP participation was associated with a higher frequency of consuming sugar-sweetened beverages (P<0.05) when respondents lived within ¼ to ½ mile of a small grocery store, supermarket, and limited service restaurant. SNAP participants who did not live close to a convenience store reported a lower frequency of sugar-sweetened beverage consumption (P=0.01), and those living more than ½ mile away from a supermarket reported a lower frequency of fruit consumption (P=0.03).ConclusionsThe findings from this study suggest that the community food environment may play a role in moderating the association between SNAP participation and eating behaviors. Although SNAP participation is associated with some unhealthy behaviors, this association may only hold true when respondents live in certain food environments.

Exposure of the U.S. Population to Acrylamide in the National Health and Nutrition Examination Survey 2003–2004

Background

The lifelong exposure of the population to acrylamide has raised concerns about the possible health effects of the chemical. Data on the extent of exposure to acrylamide and its primary metabolite, glycidamide, are needed to aid in the assessment of potential health effects.

Objectives

The aim of this study was to assess human exposure to acrylamide and glycidamide in the general U.S. population through the measurement of hemoglobin adducts of acrylamide (HbAA) and glycidamide (HbGA).

Methods

HbAA and HbGA were measured in 7,166 subjects from the National Health and Nutrition Examination Survey. Stratified HbAA and HbGA data were reported by sex, age groups, race/ethnicity (Mexican American, non-Hispanic black, non-Hispanic white), and smoking status based on serum cotinine levels. Covariate-adjusted geometric means for each demographic group were calculated using multiple regression analysis.

Results

HbAA and HbGA levels ranged from 3 to 910 and from 4 to 756 pmol/g hemoglobin, respectively, with smokers having the highest levels overall. Tobacco smoke exposure in nonsmokers had a small but significant effect on HbAA and HbGA levels. Adjusted geometric mean levels for children 3–11 years of age were higher than for adults ≥ 60 years of age [mean (95% confidence interval): HbAA, 54.5 (49.1–51.5) and HbGA, 73.9 (71.3–76.6) vs. HbAA, 46.2 (44.3–48.2) and HbGA, 41.8 (38.7–45.2)]. Levels were highest in Mexican Americans [HbAA: 54.8 (51.9–57.8), HbGA: 57.9 (53.7–62.5)], whereas non-Hispanic blacks had the lowest HbGA levels [43.5 (41.1–45.9)].

Conclusions

U.S. population levels of acrylamide and glycidamide adducts are described. The high variability among individuals but modest differences between population subgroups suggest that sex, age, and race/ethnicity do not strongly affect acrylamide exposure. Adduct concentration data can be used to estimate relative exposure and to validate intake estimates.     

Structural Analysis of the Relationships among Elementary Teachers’ Training,Self-Efficacy,and Time Spent Teaching Nutrition

Many factors determine the time elementary teachers devote to nutrition instruction. We tested theoretical models for the relationships among time spent teaching nutrition (TTN) and several aspects of the teacher's nutrition background: nutrition training, self-efficacy, knowledge, and beliefs. We proposed two models: (1) teachers with more nutrition training would have increased self-efficacy for teaching nutrition and, because of that increased self-efficacy, would teach more nutrition (primary model); and (2) both training and self-efficacy would directly and independently influence TTN (alternative model). The models differed only in one respect: whether the influence of training on TTN is direct or mediated by self-efficacy. We used data from a 1990-92 Hawai‘i Nutrition Education and Training Program needs assessment survey (N = 324 elementary teachers) and completed a structural analysis using the CALIS procedure of SAS. The primary model fit the actual data more closely than did the alternative model. Nutrition knowledge predicted self-efficacy for teaching nutrition, but a belief that nutrition instruction was important did not predict TTN. These results indicate that in elementary teachers, self-efficacy for teaching nutrition mediates the relationship between in-service training, nutrition knowledge, and TTN.
