Background:We examined the consumption patterns and the knowledge and awareness of energy drinks to draw up a guideline for energy drink consumption and to give accurate information to college student. Methods: Data from 324 subjects (186 males and 138 females) were collected using self-administered questionnaires. The study participants were recruited from the Gyeonggi-do, Seongnam area between March and June 2013. Results:The results showed that there was a significant gender-based difference in awareness of energy drinks-56.5% (78/139) of the males and 78.9% (71/90) of the females had negative awareness (P<.001). As for recognizability of taurine by awareness of energy drinks, there were intergroup differences: the mean was 3.89 for the group with positive awareness and 3.31 for the negative awareness group (P=.001). The odds ratio for awareness of energy drinks was 2.75 (95% CI:1.05-7.18) and those with positive awareness consumed more than those with negative awareness (P=.039). Conclusions: This investigation on the factors that affect energy drinks consumption behaviors is of significance in that it helps make known the high caffeine content of energy drinks, and accurate knowledge of the side effects and appropriate consumption.

Purpose: Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. Methods: We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015. The children were stratified according to the appearance of the esophagus (normal vs. MCE). Between-group differences in EGG parameters and their correlation with each MCE finding were statistically analyzed. Results: Only the power ratio, one of the EGG parameters analyzed, differed significantly between the two groups (MCE, 1.68±3.37 vs. normal, 0.76±1.06; p＜0.05), whereas the other parameters, such as dominant frequency, dominant power, and the ratio of abnormal rhythm, showed no differences. Among children with MCE, significant correlations were noted between erythema and power ratio (p＜0.05), friability and postprandial dominant frequency (p＜0.05), and edema and/or accentuation of mucosal folds and pre-prandial frequency (p＜0.05). Helicobacter pylori infection correlated with postprandial arrhythmia (MCE, 33.59±15.52 vs. normal, 28.10±17.23; p＜0.05). EGG parameters did not differ between children with normal esophagus and those with biopsy-proven chronic esophagitis. Conclusion: In children with MCE, gastric dysmotility may affect the development of MCE, manifesting as EGG abnormalities. H. pylori infection may also affect GME. However, larger prospective investigations are needed to confirm these findings.
