Suman, FACSM) Email: jmbores@utmb.edu (No relationships reported) PURPOSE: The hypermetabolic response after a severe burn results in whole body catabolism and calorie deficits leading to malnutrition and losses in lean body mass (LBM). Thus, proper nutrition after a severe burn is essential to recovery. Current practice is to increase nutritional intake by (1.2-1.5 kcal x resting energy expenditure (REE)) and protein (1.5-2.5 g protein/kg/day) to increase LBM. Research in non-burn populations suggests an ideal protein intake of 25-30 g per meal for optimal protein synthesis. However, outpatient nutritional monitoring is currently not well documented; the amount and distribution of protein among meals is unknown. Therefore, we examined the nutritional profile and distribution of substrates in severely burned pediatric outpatients in comparison to non-burned children to further direct recovery efforts to mitigate catabolism and increase LBM. METHODS: Caregivers of 23 burned children (>30% total body surface area burned) and 7 non-burned children (NB) (21 male, 9 female; 13 + 4 years; mean ± SD) completed 24-hour dietary recalls for 3 consecutive days to obtain a detailed report of foods consumed. Unpaired t-tests with Welch’s correction were performed between burned and NB children. Alpha was set at p<0.05. RESULTS: Burned children consumed significantly more kcal (3032 ± 888 kcal) than NB children (2147 ± 551 kcal, p=0.006) and averaged 1.6 x REE kcal per day. Burned patients consumed similar amounts of protein/kg body weight (2.9 ± 0.9 g) as NB children (2.0 ± 1 g/kg/day, p>0.05) and had similar distributions of protein at each meal (p>0.05). Burn patients consumed 40-52% carbohydrates, 30-37% fat and 17-18% protein in main meals; protein intake significantly differed at breakfast (p=0.007) and lunch (p=0.041) between burned and NB children. CONCLUSIONS: The data showed burned children consume more kcal than the recommended amount established for the burn population and consume roughly the same amount of total protein as NB. The protein distribution among each main meal is adequate in burned children. If further studies show that catabolism is not curbed and losses in LBM still persist in spite of adequate nutrition, other interventions such as drug therapy and exercise programs should be considered to increase LBM in severely burned children. 1157 Board #336 May 31 2:00 PM - 3:30 PM Consumption Of Sugar-sweetened Beverages By Sex And Weight Status In Children From The Mexico-US Border Luis M.

Email: luismariouabc@gmail.com (No relationships reported) It has been studied that school-age children have access to a diet with a high caloric content and low nutritional value, in addition, these population similarly consumes sugar sweetened beverages. The consumption of these beverages is associated with the development of obesity, cardiovascular disease, diabetes, cancer and metabolic syndrome. PURPOSE: To identify the frequency of consumption of sugar sweetened beverages by sex and weight status in children from the Mexico-US border. METHODS: A total of 453 students (235 girls and 218 boys) from 4 th to 6 th grade of five elementary schools in the city of Tijuana, Baja California, Mexico were measured. Height, weight and BMI was obtained by anthropometry. The questionnaire of beverage consumption (Hedrick et al 2010) was administered, to calculate the calorie and sugar content the Nutritionist Pro (v 5.2) program was used. RESULTS: The prevalence of overweight and obesity was 45%. Thirty two per cent of boys and 22% of girls consumed more than 50 grams per day of sugar from drinks. As revealed by the Mann-Whitney Test, significant differences by sex were observed in the consumption of grams of sugar per day (p = 0.001) and total calories from beverages (p = 0.002). Also, the boys reported a higher consumption of kilocalories from sugar sweetened beverages (p = 0.001) and milliliters per day (p = 0.001) than girls. No significant differences of sugar and kilocalories consumption from sugar sweetened beverages among children with normal weight and those who were overweight and obese were found. CONCLUSIONS: The results of this study indicates a high intake of sugar from drinks, which is higher than recommended by WHO. The boys reported a higher consumption of sugar sweetened beverages and kilocalories than girls. The study shows no significant differences in the sugar and kilocalories consumption by weight status. 1158 Board #337 May 31 2:00 PM - 3:30 PM Weight Loss Knowledge Among Current And Future Health Professionals In Exercise Science And Nutrition Lauren Pringle, Laurie Milliken, FACSM. UMASS BOSTON, Boston, MA. (Sponsor: Dr. Laurie Milliken, FACSM) Email: lpringle06@yahoo.com (No relationships reported) Knowledge among current and future health professionals of the most recent literature pertaining to applicability of the 3500 calorie rule for predicting weight loss is unknown. PURPOSE: To assess levels of knowledge, among those in the fields of exercise science and nutrition, of the applicability of the 3500 calorie rule for predicting weight loss (WL) over time and whether knowledge differed with a person’s training level and their perceived WL knowledge. METHODS: Students (S), faculty (F), and professionals (P) [n = 352, 68% female, 31 ± 13.5 years] responded to an anonymous online survey sent via email lists and social media platforms. Level of WL knowledge was assessed using a list of 9 statements pertaining to the 3500 calorie rule and its ability to accurately predict WL over time. Respondents were asked to identify which statements were true and were scored (0-100%) based on their correct responses. Participants also reported current exercise and nutrition certifications. They reported level of WL knowledge on a 5 point Likert scale and were divided into 2 groups: very good or excellent (EX) knowledge vs good, fair and poor (Poor) knowledge. Respondents were grouped as certified or not certified. A one-way ANOVA was used to test for differences in scores on WL facts between S, F, and P. Independent t tests were used to detect differences in scores on WL facts between certified and not certified and between EX knowledge and Poor knowledge. RESULTS: Scores on WL facts were not different between S, F, and P [64.1 ± 18.9% (n=217); 70.1 ± 19.9% (n=39); 63.5 ± 21.2% (n=96), respectively; p = 0.176]. Certified S had higher scores on WL facts than S without certifications [72.8 ± 17.9% vs 62.6 ± 18.7%, respectively; p = 0.005] while no differences in scores on WL facts existed between those with and without certifications for F [67.2 ± 19.7% vs 73.5 ± 20.2%, p = 0.335] and P [64.0 ± 20.8% vs 62.4 ± 22.7%, p = 0.748]. Those who rated themselves as having EX knowledge did not score differently than those who rated themselves as having Poor knowledge [69.8 ± 16.0% vs 69.3 ± 16.8%, respectively; p = 0.789]. CONCLUSIONS: Knowledge of WL concepts is similar among S, F, and P. Certification may enhance students’ knowledge of WL facts but does not influence knowledge for F or P. High levels of perceived knowledge may not reflect better actual knowledge of WL facts. Copyright © 2017 by the American College of Sports Medicine.
