LB017-MON COMPARISON OF EFFECTS OF DIABETIC ENTERAL NUTRITION AND STANDARD ENTERAL NUTRITION ON POSTPRANDIAL GLYCEMIA A PILOT STUDY J. Visek1 , P. Hegerova1 , L. Sobotka1 , V. Blaha1 . 1 Department of Gerontology and Metabolism, University Hospital and Medical Faculty in Hradec Kralove, Charles University in Prague, Hradec Kralove, Czech Republic Rationale: Use of standard enteral nutrition (EN) can cause hyperglycemia and associated complications. For these reasons, it may be recommended to use EN specially developed to minimize the rise in blood glucose after its administration. On the other hand, these formulas often contain small amount of proteins, which could be a disadvantage for clinical practice. Methods: Type 2 diabetes mellitus patients treated with diet or oral hypoglycaemic agents were involved in the study. Three types of EN were investigated: Nutrison MF (standard EN), Diben drink (regular hypocaloric diabetic nutrition) and Glucerna Select (isocaloric diabetic nutrition). We measured blood glucose at baseline and 15, 30, 45, 60, 90 and 120 min after ingestion of solution containing 25 g of carbohydrates. Blood samples were obtained from venous cannula. The effect on postprandial glycemia of EN was compared with the effect of glucose solution administered under the same conditions. Upward parts of the area under the curve were compared and used to calculate glycaemic index (GI). Measurements were repeated 3 times for each solution. Results: Until now, measurements were performed on 6 volunteers. The GI (shown as mean ± standard deviation) of Nutrison MF was 62.5±20.2, Diben drink 48.2±7.6 and Glucerna Select 28.1±7.5. Statistical analysis was performed by One Way RM ANOVA. Results of GI after Nutrison MF were statistically different from Glucerna Select.

Conclusion: Our results are limited by a small number of measurements. Yet, there is significant trend showing a lower increase in postprandial glycemia in diabetic nutrition especially in diabetic isocaloric nutrition, but it will have to be further verified.

LB018-MON RELATIONSHIP BETWEEN BONE MINERAL DENSITY AND NUTRITIONAL INTAKE AMONG FEMALE HIGH SCHOOL TRACK AND FIELD ATHLETES A. Ikedo1 , A. Ishibashi1 , S. Matsumiya1 , A. Kaizaki2 , A. Yuhaku1 , S. Fujita1 , E. Kumiko1 . 1 Graduate School of Sport and Health Science, 2 Ritsumeikan Global Innovation Research Organization, Ritsumeikan University, Kusatsu, Japan Rationale: Stress fractures occur at peak at sixteen years old, especially among female track and field athletes, and low bone mineral density (BMD) is one of the risk factors of stress
fractures. However, among female runners <18 years old, less stress fractures and higher BMD was observed in those who often take in particular nutrients, and eat dairy, fruits and vegetables. The purpose of this study was to observe the relationship between BMD and nutrient intake which affects bone metabolism among female high school track and field athletes. Methods: Forty-nine female high school runners (age: 16.2±0.7 y) participated in the study. Prior stress fracture and menstrual state were asked using questionnaires. Nutrient intake was assessed with a food frequency questionnaire. BMD, bone mineral content (BMC) and body fat percentage were measured by DXA. Results: With regard to BMD and nutritional intake, there were a significant positive correlation between the dairy products intake and both legs’ BMD (r = 0.31, p < 0.05), and there was a positive correlation between protein and hip BMD (r = 0.3, p < 0.05). In addition, among those without adequate intake of vitamin D (4.5 mg <), there was a significant correlation with vitamin D intake and both legs’ BMD (r = 0.46, p < 0.05). Furthermore, there was a significant positive correlation between vitamin B2 intake and the TBLH BMC (r = 0.57, p < 0.01) among those without estimated average requirement of vitamin B2 intake (1.1 mg <). Conclusion: It is concluded that female high school track and field athletes without sufficient intake of dairy products, protein, vitamin D and vitamin B2 were associated with low BMD and/or BMC.

Dimopoulos3 . 1 Department of Hygiene, Epidemiology and Medical Statistics, University of Athens Medical School, Athens, Greece; 2 Faculty of Medicine, Imperial College London, London, United Kingdom; 3 Department of Clinical Therapeutics, University of Athens Medical School, Athens, Greece Rationale: This meta-analysis aims to evaluate the association between overweight/obesity and risk for Hodgkin’s lymphoma (HL), taking into account the possible modifying role of gender. Methods: Potentially eligible articles were sought in PubMed with a predefined search algorithm and no language restrictions were adopted (end of search date: January 31, 2014). Two authors working independently performed the selection of studies and data extraction. Overweight and obesity were defined as Body Mass Index (BMI) 25.0 29.9, and >30 kg/m2 , respectively. Random effects models (DerSimonian-Laird) were implemented for the calculation of the pooled relative risk (RR) estimates; separate analyses were performed by gender. Analysis was performed with STATA/SE 13 statistical software; this study was funded by Wereld Kanker Onderzoek Fonds (WCRF NL) administered by WCRF International. Results: Eight cohort studies were deemed eligible, corresponding to a total cohort size of 4,959,891 subjects among whom 1,842 incident HL cases were noted. Obesity
