Objectives: The study examined the status on the use of nutrition labeling and nutrition claims among university students as well as the diet quality and nutritional status using the nutrition quotient (NQ) according to the use of nutrition labeling and claims. Methods: A cross-sectional survey was conducted on university students (86 males and 131 females) from March to April in 2019 in Chungbuk area. Results: The percentage of subjects who reported that they recognized nutrition labeling was 80.2% of the total, and 63.8% of them indicated that they used nutrition labeling for their food choices. In addition, 22.6% of the total subjects said that they used nutrition claims. The group of subjects using nutrition labeling showed significantly higher mean scores in balance (P < 0.01), diversity (P < 0.05), moderation (P < 0.01), and dietary behavior (P < 0.001) along with higher mean NQ score (P < 0.001) compared to the group not using nutrition labeling. The group using nutrition claims had significantly higher mean scores in balance (P < 0.001), diversity (P < 0.01), moderation (P < 0.001), and dietary behavior (P < 0.001) as well as total NQ scores (P < 0.001) compared to the group not using nutrition claims. The group of subjects using both nutrition labeling and nutrition claims showed significantly higher mean NQ scores than the group of subjects using either nutrition labeling or nutrition claims (P < 0.05). Conclusions: In this study, university students' use of nutrition labeling and nutrition claims appeared to be related to their diet quality and nutritional status.

Background: Determination of inter-method differences between clinically available volumetry methods are essential for the clinical application of brain volumetry in a wider context. Purpose: The purpose of this study was to examine the inter-method reliability and differences between the Siemens morphometry (SM) software and the NeuroQuant (NQ) software. Materials and Methods: MR images of 86 subjects with subjective or objective cognitive impairment were included in this retrospective study. For this study, 3D T1 volume images were obtained in all subjects using a 3T MR scanner (Skyra 3T, Siemens). Volumetric analysis of the 3D T1 volume images was performed using SM and NQ. To analyze the inter-method difference, correlation, and reliability, we used the paired t-test, Bland-Altman plot, Pearson's correlation coefficient, intraclass correlation coefficient (ICC), and effect size (ES) using the MedCalc and SPSS software. Results: SM and NQ showed excellent reliability for cortical gray matter, cerebral white matter, and cerebrospinal fluid; and good reliability for intracranial volume, whole brain volume, both thalami, and both hippocampi. In contrast, poor reliability was observed for both basal ganglia including the caudate nucleus, putamen, and pallidum. Paired comparison revealed that while the mean volume of the right hippocampus was not different between the two software, the mean difference in the left hippocampus volume between the two methods was 0.17 ml (P < 0.001). The other brain regions showed significant differences in terms of measured volumes between the two software. Conclusion: SM and NQ provided good-to-excellent reliability in evaluating most brain structures, except for the basal ganglia in patients with cognitive impairment. Researchers and clinicians should be aware of the potential differences in the measured volumes when using these two different software interchangeably.

The purpose of this survey was to investigate the food behavior and vegetable preferences of elementary school students in the metropolitan areas of, South Korea. Five hundred and eighty students (277 male and 303 female) studying in grades 5~6 participated in the survey. We assessed food behavior by evauating the Nutrition Quotient (NQ). Through a questionnaire, which consisted of 20 food behavior checklist items. These items were grouped under five factors: balance, diversity, moderation, practice and environment. All data were analyzed using SPSS 25.0. The average NQ score weighted using the five factors was 61.32 points. Among the five factors, moderation showed the lowest score, whereas environment showed the highest score. The average score of the vegetable preference was 3.36 points out of a total of 5 points. The vegetable preference was found to be highest for bean sprouts and followed by tomatoes, lettuce, spinach, Chinese cabbage, sesame leaf, pumpkin, carrot, radish, chives, lotus roots, onions, broccoli, sweet peppers, and eggplant. The results of vegetable preferences by NQ grade were 4.13±0.63 points for the high grade, 3.68±0.75 points for the medium-high grade, 3.41±0.82 points for the medium-low grade, and 2.94±0.78 points for the low grade. There was a significant positive correlation between NQ and vegetable preferences (r=0.477, P<0.001). If vegetables with high preference are frequently provided in school meals, it might contribute to improving overall food behavior.

This study aimed to provide fundamental data that could guide high school students' night eating behavior by investigating habits of their night eating consumption during COVID-19 pandemic (From 2021/5/13 to 5/20). Association between their eating habits and the Nutrition Quotient for Korean Adolescents (NQ-A) were also explored. This study included a total of 604 students, among whom 441 students were identified as night eating consumers. Among all subjects, 30.5% consumed night eating 3~4 times a week, 27.3% consumed 1-2 times a week, and 27.0% did not consume any night eating at all. The high-night eating group had a higher score of total NQ-A than the non-night eating group for both male (p<0.05) and female (p<0.001) students. This was because male students in the high-night eating group reported significantly higher rates of daily dinner consumption compared to non-night eating group. Furthermore, both male (p<0.05) and female (p<0.001) students showed a significant increase in 'Moderation'. 'Diversity' was also significantly increased in female studies (p<0.05) as subcategories of dietary habits according to night eating frequency. These findings highlight the need for practical research to develop nutritional guidelines for night eating that reflect preferences of students while providing adequate nutritional habits.

Objective: To compare two clinically available MR volumetry software, NeuroQuant^® (NQ) and Inbrain^® (IB), and examine the inter-method reliabilities and differences between them. Materials and Methods: This study included 172 subjects (age range, 55-88 years; mean age, 71.2 years), comprising 45 normal healthy subjects, 85 patients with mild cognitive impairment, and 42 patients with Alzheimer's disease. Magnetic resonance imaging scans were analyzed with IB and NQ. Mean differences were compared with the paired t test. Inter-method reliability was evaluated with Pearson's correlation coefficients and intraclass correlation coefficients (ICCs). Effect sizes were also obtained to document the standardized mean differences. Results: The paired t test showed significant volume differences in most regions except for the amygdala between the two methods. Nevertheless, inter-method measurements between IB and NQ showed good to excellent reliability (0.72 < r < 0.96, 0.83 < ICC < 0.98) except for the pallidum, which showed poor reliability (left: r = 0.03, ICC = 0.06; right: r = -0.05, ICC = -0.09). For the measurements of effect size, volume differences were large in most regions (0.05 < r < 6.15). The effect size was the largest in the pallidum and smallest in the cerebellum. Conclusion: Comparisons between IB and NQ showed significantly different volume measurements with large effect sizes. However, they showed good to excellent inter-method reliability in volumetric measurements for all brain regions, with the exception of the pallidum. Clinicians using these commercial software should take into consideration that different volume measurements could be obtained depending on the software used.

The digital environment has become an integral part of human lives today. This study aimed to investigate Mukbang watching status and its association with eating behaviors, eating habits, and the nutritional status of children. We conducted a survey of the actual status of Mukbang watching, and nutrition quotient of children (NQ-C) among 222 students in elementary schools in Daejeon. The prevalence of viewing Mukbang content was 68.9%, the most common frequency of viewing was 1~2 times per month (36.5%), and the duration of watching a single episode was less than 10 minutes (54.9%). Overall, 31.4% of students responded that they ate while watching a Mukbang and, 66.0% said they felt hungry after watching a Mukbang. YouTube (82.4%) was the most common source of viewing Mukbang. The most common reason for watching Mukbang was because all the students found the content entertaining. The NQ-C score of all the subjects surveyed was 58.95, which is a moderate grade. The scores of NQ-C, balance, and practice factors were significantly higher in boys than in girls. In addition, the scores of NQ-C, and balance and moderation were significantly higher in Mukbang non-viewers than viewers for all subjects and more specifically boys. These results suggest that watching Mukbang is associated with poor nutritional status in elementary school children. Therefore, it is necessary to consider the Mukbang watching status when providing nutrition guidance to instill healthy eating habits in children.
