Purpose: Consumers’ use and interpretation of trans fat information on food labels were explored. Methods: Consumers completed an interviewer-administered questionnaire in one of three grocery stores selected purposively to represent geographical location. Data analysis involved examining the relationship of age, gender, grocery shopping habits, household size, and source of nutrition information with awareness, use, and interpretation of trans fat information. Results: Ninety-eight percent (n=239) of participants were aware of trans fat, and most knew of the relationship between trans fat intake and cardiovascular disease. Although the majority of shoppers were aware of the “0 trans fat” nutrition claim on food packages (95%), they were more likely to use the Nutrition Facts panel (60%) to reduce trans fat intake. Men and consumers under age 40 were least likely to be aware of food label information. While most consumers (75%) correctly interpreted the “0 trans fat” nutrition claim and thought foods with this claim could be healthy choices (64%), only 51% purchased these foods to reduce trans fat intake. Conclusions: Nutrition professionals should target messages to reduce trans fat intake at men and consumers under age 40. While general knowledge was good, further education is required to help consumers interpret trans fat information.

Purpose: We explored whether Canada's diverse ethnic population consumes an adequate daily amount of fruit and vegetables. We also examined the association between fruit and vegetable consumption and long-term diseases. Methods: The Canadian Community Health Survey, Cycle 2.2 (CCHS 2.2), was used to determine the fruit and vegetable intake (FVI) of 13 racial groups, as well as of the entire population. Specifically, we determined median intake and proportions of the group consuming five or more daily servings. Multiple pairwise comparisons among the proportions were performed to detect ethnic groups with significantly low FVI. Logistic regression was also used to describe the risk of longterm diseases associated with FVI and ethnicity. Results: The percentages of Southeast Asian, Aboriginal (offreserve), and Chinese people who consumed five or more daily servings of fruit and vegetables were significantly lower than percentages in all other ethnic groups surveyed. Aboriginal people with the lowest FVI demonstrated the highest propensity for developing most of the long-term diseases. Conclusions: The majority of Canada's ethnic groups identified in the CCHS 2.2 fell short of the recommended FVI target. This low-intake status might be a risk factor for common long-term diseases.

Purpose: Healthful lifestyle habits established in childhood may continue through adulthood. Such habits may also be effective in preventing or reversing overweight and obesity. However, little is known about children's perceptions of healthful eating and physical activity. Thus, we sought a better understanding of how children perceive healthful eating and physical activity. Methods: A purposeful selection was made of Winnipeg, Manitoba, boys (n=23) and girls (n=22) aged 11 to 12 years. The children were interviewed using a semi-structured, indepth interview guide. Data were analyzed using thematic coding. Results: Although healthful eating was seen as necessary for health, high-fat, high-sugar foods were a source of pleasure and enjoyed during social times. Physical activity was a way of spending time with friends, either through active play or watching sports. Boys viewed screen time and homework as barriers to physical activity, while girls identified no common barriers. Children viewed physical activity as easier than healthful eating, describing the former as “play” and “fun.” Conclusions: Knowing how children think about food choices will further our understanding of the disconnect between nutrition knowledge and dietary behaviours. Understanding conflicting pressures that influence children's healthful lifestyles may enhance communication about these topics among parents, educators, and children.

Purpose: We explored advanced practice (AP) across the diversity of dietetics to develop a definition, description, and framework for guiding future education, research agendas, and policy development. Methods: The process began with a literature review and discussion with dietitians exploring AP in other countries. Various concepts were identified, and these informed the phase 1 survey questions. Phase 1 was a 36-item survey created in SurveyMonkey, engaging a purposeful sample of key stakeholders (n=136). A modified Delphi approach, involving seven dietitians from different geographical locations and practice areas, finalized the phase 2 survey. An e-mail link to this 50-item survey was sent to a random sample of dietitians (n=885). The proposed AP framework entailed an iterative approach, integrating survey results with AP literature. Results: Response rates were 40% for phase 1 and 35% for phase 2. In phase 1, 83% of respondents agreed that a depth and breadth definition captured all dietetic job roles, and 95% agreed that it differentiated AP from entry-level practice. Descriptive statistics are presented to provide demographic information and level of agreement with themes relevant to AP. Conclusions: A framework is presented, and discrepancies with phase 2 results indicate areas for professional development, such as leadership, mentorship, and outcome measurement.

Purpose: In this study, we sought insight into the clinical practice experiences of dietitians working independently (i.e., as the only dietitian in a facility) in long-term care (LTC). We hoped to learn about their work roles and identify specific factors that facilitate their success. Methods: Grounded theory methods were used. Data were collected through 11 semi-structured interviews. Verbatim transcripts were analyzed using a constant comparative method, which included coding, memo writing, and ongoing discussion between the two researchers. Results:When speaking about their roles, participants identified both specific tasks they had to complete and broader roles they fulfilled. Many of these roles focused on relationships with co-workers and building effective multidisciplinary teams. Effective teamwork was linked with dietitians’ personal feelings of success in providing resident-focused nutritional care in the LTC setting. Conclusions: The LTC dietitians’ various roles were generally self-appointed, and they focused more on the purpose of their work than on tasks. A primary focus of these roles was the multidisciplinary team and the promotion of effective teamwork, especially, but not exclusively, as it applies to the provision of nutritional care. Successful teamwork was linked to dietitians’ reports of personal success in their work.

Perspectives in Practice

A web-based cross-country survey of renal registered dietitians (RRDs) was launched. It was used to assess whether or not their clinical practice in identifying and treating proteinenergy malnutrition (PEM) in adults with end-stage renal disease (ESRD) and dialysis was based on current nutrition practice guidelines (NPGs). The survey included questions on strategies, timelines, and markers used for the identification and treatment of PEM. Fifty-nine RRDs responded (21%). Sixty-seven percent did not base clinical practice on NPGs, while 33% indicated they followed the guidelines. Of those who followed guidelines, 76% use the National Kidney Foundation— Kidney Disease Outcomes Quality Initiative nutrition guidelines. Strategies used to identify and treat PEM were not related to duration of RRD experience in nephrology, but were significantly different between guidelines users and non-users. Guideline users commonly used key nutrition treatment strategies that included enteral/parenteral nutrition and medication therapy. The clinical practice of RRD is typically based on expert opinion/consensus, rather than on evidence-based practice guidelines (EBPG). It remains unclear if differences in RRDs’ adoption of clinical guidelines influences patient outcomes, particularly in the treatment of PEM. Up-to-date EBPG need to be developed for the identification and treatment of PEM in patients with ESRD.

Evaluation of university-run dietetic internship programs will improve preceptors’ experience and, ultimately, increase the capacity for training future dietitians. We attempted to identify preceptors’ perceptions of their roles, benefits, and supports, as well as of the skills/traits that students need for internship, and suggested improvements for the internship program. Fifteen of 39 current program preceptors who had supervised more than one intern consented to participate in an ethics-approved research methodology. They responded anonymously to a series of questions posted in an online discussion group, and provided feedback on the subsequent reports. While no consensus emerged, more than 50% of participants perceived their role as providing a supportive learning experience for interns. Benefits noted most frequently were personal academic growth and contributions to their organizations from intern research projects. Effective supports included conventional communication methods and website materials. Participants identified self-motivation, independence, and communication skills as most important for interns. They also provided several suggestions for program improvements. The study methods and results could be helpful to other universityrun internship programs seeking improvement and growth.

Pregnant women's fish consumption provides both benefits and risks to the developing fetus. Docosahexaenoic acid (DHA) from fish may enhance fetal neurodevelopment, while methylmercury (MeHg) can have detrimental effects. Dietitians would benefit from information on the frequency with which fish species may be consumed to increase DHA intake among Canadian women of childbearing age, and on minimizing the risks from MeHg, especially for those who consume fish frequently. Eighteen fish species were selected for DHA and mercury analysis from retail markets in the Toronto area. Consumption scenarios using analytical results for these fish species indicate that women of childbearing age can consume nine of 18 fish species every day (14 servings a week) or often (up to four servings a week) and remain below toxicological benchmarks for mercury. Moreover, women can also attain the recommended DHA level by consuming six of those nine fish: four 75-g servings of smelt, porgie, or bluefish a week, or two 75-g servings of milkfish, silver pomfret, or tilapia a day. Our analysis indicates that the DHA level recommended for childbearing women can be attained through fish consumption alone, without the need for supplementation and without posing a risk to the woman (or the fetus) from mercury.

Purpose: Few authors have investigated the institutional character of charitable food programs and their capacity to address food security in Canada. Methods:We surveyed food programmanagers at charitable agencies in Greater Victoria, British Columbia.We discuss the structure of the “system” of charitable food provision, the value of sourced food, types of services provided, clients’ demographic profile, and the estimated healthfulness ofmeals served.We also describe the proportion ofmajor food types purchased and donated to agencies. Results: Thirty-six agencies served approximately 20,000meals a week to about 17,000 people. Food valued at $3.2million was purchased or donated; approximately 50%was donated,mainly by corporations. The largest value of food purchased and donated was frommeat and alternatives (40.9%) and nonperishable food items (16%). Dairy productsmade up the smallest share of donated foods. Conclusions: Charitable food programs in Victoria depend on food donations. The proportion of dairy products and produce is low, which raises questions about the healthfulness of foods currently fed to homeless and poor people in the city.

Purpose: Dietary vitamin D intake was assessed among residents in a long-term care (LTC) facility, so that recommendations could be made about vitamin D supplementation. Methods: Three-day tray audits were completed for allmeals and snacks, including nutritional supplements (Boost™and/or high-protein pudding). Total daily and three-day vitamin D intake was calculated for each resident, and the total sample was compared with the recommended Adequate Intake (AI) of 600 IU. Vitamin D content was calculated using the Canadian Nutrient File and product labels. Resident charts were reviewed for micronutrient supplements and diagnoses. Results: The daily average vitamin D available to and consumed by 30 residents was 414 IU and 295 IU, respectively. Those provided with nutritional supplements received an average of 480 IU and consumed 357 IU, while those without received an average of 245 IU and consumed 207 IU. Thirty-three percent of residents were diagnosed with osteoporosis, osteoarthritis, and falls and/or fractures. Vitamin Dmicronutrient supplementation varied from above 600 IU (43%) to below 600 IU (30%) to no supplementation (27%). Conclusions:None of the study participantsmet the recommended AI of 600 IU through dietary sources alone. Study results suggest that all LTC residents require vitamin Dmicronutrient supplementation of at least 400 IU to achieve the recommended AI of 600 IU.

Growth monitoring and promotion of optimal growth are essential components of primary health care for infants, children and adolescents. Growth monitoring includes serial measurements of weight, length or height for all children, head circumference for infants and toddlers, and interpretation of those measurements relative to the growth of a large sample population of children depicted on a selected growth chart. These measures help to confirm a child's healthy growth and development, or identify early a potential nutritional or health problem. This enables health professionals and parents to initiate action before the child's nutritional status or health are seriously compromised. Over the last three decades there has been substantial discussion on which reference population to use in assessing adequacy of childhood growth. In 2004, Dietitians of Canada, Canadian Paediatric Society, The College of Family Physicians of Canada and Community Health Nurses of Canada published recommendations for use of the 2000 American growth charts from the Centers for Disease Control and Prevention. At that time, limitations of the charts were noted, including the fact that these charts were growth references, describing how a sample population of children grew, regardless of whether or not their rate of growth was optimal or not. It was also noted that the decision on which growth charts to recommend would be revisited as more appropriate data became available. Increasing evidence that growth patterns of well-fed healthy preschool children from diverse ethnic backgrounds were comparable, supported the use of a single international growth reference based on healthy, wellnourished children from different geographic and genetic origins, who had fully met their growth potential. Until recently, no such growth charts existed. In 2006, the World Health Organization (WHO), in conjunction with the United Nations Children's Fund and others, released new international growth charts depicting the growth of children from birth to age five years, who had been raised in six different countries (Brazil, Ghana, India, Norway, Oman, USA) according to recommended nutritional and health practices, including exclusive breastfeeding for the first four to six months of life. The optimal growth displayed in the WHO growth charts for infants and preschool children represents the prescribed gold standard for children's growth; hence these charts are considered growth standards. In 2007, the WHO also released charts for monitoring the growth of older children and adolescents that had been updated and improved to address the growing epidemic of childhood obesity. Dietitians of Canada, Canadian Paediatric Society, The College of Family Physicians of Canada, and Community Health Nurses of Canada make the following recommendations, intended as a practice guideline for medical practitioners and other health professionals. The desired outcome is that wide dissemination of these recommendations will promote consistent practices in monitoring growth to improve the nutritional status and health outcomes of Canadian infants, children and adolescents.
