Learning Outcome: After this presentation, the attendee should be able to navigate the Internet for nutrition information with more diligence to decipher blog credibility according to indicators of author credentials, evidence based references, disclaimers, and the lack of promotions or services. The attendee, if a nutrition-related professional, should be able to design a blog that produces indicators of reliability and thus be sought as a dependable resource for nutrition information.
Learning Outcome: Participants will learn how MUAC z-scores correlate with BMI z-scores in assessing malnutrition. Background: MUAC is a recommended measurement in pediatric nutritional assessment but has limited usefulness with present WHO standards. We developed and evaluated MUAC growth curves for ages 2 mos to 18 years.
Background: The Internet has become a widely used source for information, suggesting increased availability of material without supportive evidence. There is a lack of standards to ensure nutrition content displayed on blogs is scientifically sound, raising concerns of the reliability of nutrition blogs. This content analysis aimed to examine characteristics indicating credibility in active nutrition blogs.
Methods: This IRB approved study permitted retrospective data collection of age, gender, height, weight, BMI, MUAC, and assigned malnutrition classification. BMI z-score and MUAC z-score were prospectively calculated using Lambda Mu Sigma values determined from CDC-NHANES data.
Methods: Nutrition blogs (n¼75) were identified as active then analyzed for credentialed authors, disclaimers, references, and promotional products or services. Frequencies were calculated using SPSS to quantify characteristics of nutrition blogs.
Statistical Analysis: The correlation between BMI z-score and MUAC z-score was examined using non linear regression. The discriminatory power of both z-score values to detect the assigned malnutrition classification was examined by exploring mean z-scores for each group (unpaired t-test) and the confidence limits around the z-score value at each classification.
Results: Overall, 62.7% of the blogs analyzed had a Registered Dietitian (RD) or Doctor of Medicine (MD) amongst the authors. While there was a higher frequency of evidencebased references among blogs authored by RD’s compared to non-RD’s (60.9% vs. 44.8%), there was no significant difference in frequency of promoting personal services among blogs authored by RDs and non-RDs. Only 28% of nutrition blogs did not have a presence of offered services while 58% seemed to receive compensation. Only 54.6% of the blogs that presented references at least sometimes had references from peer reviewed sources. Conclusion: Overall, we found that the majority of nutrition blogs examined are not
Results: To date, data from 450 children (55% male) were available for analysis. MUAC z-score could be determined for 100% of children while BMI zscore could be ascertained only in those over 2 years (75%). BMI z-score and MUAC z-score were reasonably well correlated (r¼0.804). Both measures clearly discriminated children who were overweight/obese vs. those with no evidence of malnutrition vs. those with some degree of malnutrition (p<0.01).
meeting characteristics that indicate credibility, even amongst those authored by qualified nutrition professionals. This suggests a need for Registered Dietitians and other nutrition professionals to maintain an ethical code of conduct to ensure avoidance of false or misleading information provided on nutrition blogs.
Conclusions: MUAC z-score provides a mechanism for assessing nutritional status that performs comparably to BMI z-score but expands the population of patients than can be evaluated to include children below the age of 2 years.

Learning Outcome: Participants will be able to assess the value of fiber diets related to glycemic control found in the literature.
Learning Outcome: Determine what practice activities are perceived to be competently performed at the Advanced Practice Level (ALP).
Background: Over 29 million Americans have been diagnosed with diabetes. Achieving blood glucose control reduces the risk of eye, nerve, and kidney complications. It has been suggested that consuming carbohydrates that are rich in fiber improves glucose control. The objective of this review was to systematically assess literature published after 2008 regarding the beneficial effects of dietary fiber from whole foods and dietary supplements on diabetic adults.
Background: Past research has explored practice activities essential for Advanced Practice Registered Dietitian Nutritionists (APRDNs) in clinical practice.

Methods: The search for eligible studies was performed using the electronic databases PubMed, Cochrane Library, MEDLINE, CINAHL Complete, and SPORTDiscus. The search yielded 557 articles. The search plan and terminology was modeled after the 2008 EAL systematic review for fiber and diabetes. Results: A total of 17 articles met all the inclusion criteria. Both the data from the 2008 EAL summary and all the most current review of literature support diets providing 30-50g fiber per day from whole food sources and a relation to lower postprandial serum glucose levels compared to low fiber diets. Five articles also provided evidence for 10-35 gram per day fiber supplements and some glycemic control benefit. It is unclear if fiber from whole foods or from supplements provide benefits in long-term glycemic control or improvement in blood lipids. Conclusion: Overall, dietitians and other health professionals working with diabetic patients should encourage a diet that focuses heavily on foods providing both soluble and insoluble fibers, including fruit, vegetable, legume, and whole grain sources. For patients who struggle to meet whole food recommendations, fiber supplementation may be beneficial. Funding Disclosure: None

Objective: The aims of this study were to identify where advanced-level practice (ALP) activity statements identified in a 2009-2010 Delphi study of APRDN activities are on the practice spectrum. Design/Participants: A mixed-mode survey was administered to APRDNs identified using ALP screening criteria. Participants rated 129 activity statements from advanced to novice level practice on a 7-point Likert scale. Findings were compared to the 2009-2010 Delphi results. Statistical Analyses Performed: Median ratings (n and %) were reported for each statement and grouped by practice level: 1-3¼advanced; 4¼beyondentry-level (BEL); 5-7¼novice. Ratings were reported with n and % by level of practice category. Results: Forty-three percent of eligible RDNs (n¼53) responded. Of the 129 activity statements, 40.3% (n¼52) were rated as ALP, 0% (n¼0) was rated as BEL, and 59.7% (n¼77) were rated as novice. Of the Nutrition Assessment statements, 55% (n¼33) were rated as ALP; 62.5% (n¼5) of Nutrition Diagnosis statements were rated as ALP. Of the Nutrition Intervention and Nutrition Monitoring and Evaluation statements, 23.1% (n¼12) and 22.2% (n¼2) were rated as ALP respectively. Conclusion: Forty percent of practice activity statements identified as essential to ALP in the 2009-2010 Delphi study were rated as activities that should be competently performed by APRDNs. Future research should explore activities performed by practice level within specialty practice areas. Funding Disclosure: None
