Purpose: This study aimed to describe adult living donor liver transplantation (LDLT) for acute liver failure and evaluate its clinical significance by comparing its surgical and survival outcomes with those of deceased donor liver transplantation (DDLT). Methods: We retrospectively reviewed the medical records of 267 consecutive patients (161 LDLT recipients and 106 DDLT recipients) aged 18 years or older who underwent liver transplantation between January 2006 and December 2020. Results: The mean periods from hepatic encephalopathy to liver transplantation were 5.85 days and 8.35 days for LDLT and DDLT, respectively (P = 0.091). Among these patients, 121 (45.3%) had grade III or IV hepatic encephalopathy (living, 34.8% vs. deceased, 61.3%; P < 0.001), and 38 (14.2%) had brain edema (living, 16.1% vs. deceased, 11.3%; P = 0.269) before liver transplantation. There were no significant differences in in-hospital mortality (living, 11.8% vs. deceased, 15.1%; P = 0.435), 10-year overall survival (living, 90.8% vs. deceased, 84.0%; P = 0.096), and graft survival (living, 83.5% vs. deceased, 71.3%;P = 0.051). However, postoperatively, the mean intensive care unit stay was shorter in the LDLT group (5.0 days vs. 9.5 days, P < 0.001). In-hospital mortality was associated with vasopressor use (odds ratio [OR], 3.40; 95% confidence interval [CI], 1.45–7.96; P = 0.005) and brain edema (OR, 2.75; 95% CI, 1.16–6.52; P = 0.022) of recipient at the time of transplantation. However, LDLT (OR, 1.26; 95% CI, 0.59–2.66; P = 0.553) was not independently associated with in-hospital mortality. Conclusion LDLT is feasible for acute liver failure when organs from deceased donors are not available.

Background: This study aimed to evaluate the prevalence of dysmenorrhea and to investigate the effect of weight changes or unhealthy weight control behaviors on dysmenorrhea in young Korean women. Methods: We used large-scale data of women, aged 14 to 44 years, who participated in the Korean Study of Women’s Health-Related Issues. Dysmenorrhea was measured using a visual analog scale and was categorized as none, mild, moderate, and severe according to the severity. Weight changes and unhealthy weight control behaviors (any of the behaviors, fasting/meal skipping, drugs, the use of unapproved dietary supplements, and one-food diets) over the past year were self-reported. We used multinomial logistic regression to investigate the association between weight changes or unhealthy weight control behaviors and dysmenorrhea. Results: Of the 5,829 young women participating in the study, 5,245 (90.0%) participants experienced dysmenorrhea [2,184 (37.5%) had moderate and 1,358 (23.3%) had severe].After adjusting for confounders, the odds ratios for moderate and severe dysmenorrhea in participants with weight changes ≥ 3 kg (vs. < 3 kg) were 1.19 (95% confidence interval:1.05–1.35) and 1.25 (95% confidence interval: 1.08–1.45), respectively. The odds ratios in participants with any unhealthy weight control behaviors were 1.22 (95% confidence interval:1.04–1.42) and 1.41 (95% confidence interval: 1.19–1.67) for those with moderate and severe dysmenorrhea, respectively. Conclusion Weight changes (≥ 3 kg) or unhealthy weight control behaviors are common among young women, which may adversely affect dysmenorrhea. Therefore, attention needs to be paid to excessive weight changes and unhealthy weight control behaviors to improve dysmenorrhea in young women.

BACKGROUND/OBJECTIVES: This study examines life stress, dietary attitudes, and snacking frequency for college students living in Seoul and Gyeonggi Province. The purpose of this study is to assist college students feeling stressed by offering desirable dietary attitudes and choices of the appropriate snacks by providing educational materials that offer appropriate nutrition education and nutritional information. SUBJECTS/METHODS: A survey was conducted on a total of 600 college students aged 19–29-year-olds living in Seoul and Gyeonggi Province (234 male students and 366 female students). Collected data were analyzed using SPSS WIN 28.0 program. RESULTS: Life stress among college students did not differ significantly between the genders. Male students were more stressed about lover (P < 0.01), while female students were more stressed about value problems (P < 0.01) and future problems (P < 0.05). Dietary attitude ratings were 3.1 for both male and female students with no significant difference. The overall snacking frequency was 4.1 times/day—4.2 times/day for male students and 4.0 times/day for female students—thus, there was no significant difference. Male students consumed ‘beverage’ (P < 0.01) more frequently than female students. Life stress and snacking were positively correlated for ‘biscuit/cookie,’ ‘chip,’ ‘cereal,’ ‘juice/smoothie,’ ‘café americano,’ ‘café latte,’ ‘tea,’ ‘jelly,’ ‘chocolate,’ ‘rice cake,’ ‘milk,’ ‘flavored milk,’ and ‘ice cream’ among male students. Among female students, life stress and snacking were positively correlated with ‘cereal,’ ‘caramel,’ and ‘soymilk,’ and negatively correlated for ‘biscuit/cookie’ and ‘carbonated drink.’ CONCLUSIONS College students should manage their stress by identifying its causes and learning how to deal with stressful situations. Additionally, providing them with proper nutrition education based on the correct nutritional information is essential for promoting good food attitudes and snacking behaviors.

BACKGROUND/OBJECTIVES: The study was performed to investigate the degree of perceived stress by sex in middle-aged people, and to provide basic data for appropriate nutrition education and interventional measures for middle-aged subjects through comparative analysis of association between stress and dietary habits, emotional eating behavior, and insomnia. SUBJECTS/METHODS: A survey was conducted in 670 middle-aged subjects (320 men and 350 women) aged 40–64 years, resided in Seoul and Gyeonggi area. Collected data were analyzed using SPSS WIN 25.0 program. RESULTS: Perceived stress in middle-aged subjects was not different by sex. Stress was higher in men with low dietary habits level compared to other groups (P < 0.001), and was higher in women with low and moderate dietary habits level compared to women with high dietary habits level (P < 0.05). Stress in men was higher in the group with emotional eaters (P < 0.05), and the same result was shown in women (P < 0.001). Stress was higher in both men and women with poor sleep quality (P < 0.001). Stress score was positively correlated with emotional dietary behavior and insomnia (P < 0.001) and negatively correlated with dietary habits (P < 0.001). CONCLUSIONS It is considered that proper nutrition education and interventional measures according to sex are needed for stress control and proper dietary behavior and lifestyle in middle-aged people population, along with projects and policies at the national level.

BACKGROUND/OBJECTIVES: This study analyzed the quality of lunches provided in senior leisure service (SLS) facilities and compared institutional foodservice (IF) and noninstitutional foodservice (non-IF). SUBJECTS/METHODS: Data of 390 adults aged 65 years or older who ate lunches in SLS facilities were analyzed using the information from the 2013–2017 Korea National Health and Nutrition Examination Survey. The participants were classified into IF (n = 129) and non-IF (n = 261) groups according to meal type provided. The intake of major food groups, energy and nutrients, and nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were analyzed. The diversity of meals was evaluated by food group patterns, dietary diversity score (DDS) and dietary variety score (DVS). Energy intake was adjusted in model 1, while energy and sex were adjusted in model 2. All confounding variables were adjusted in model 3. RESULTS: The intake of seafoods (P < 0.001 in models 1, 2, and 3), seaweeds (P < 0.01 in models 1 and 2), and dairy products (P < 0.05 in models 1, 2, and 3) was significantly higher in the IF group. No significant difference existed in energy intake; however, the intake of all nutrients except carbohydrate and vitamin C was significantly higher in the IF group. NAR of all nutrients, excluding vitamin C, was higher in the IF group, and MAR was also higher in the IF group (P < 0.001 in models 1, 2, and 3). The IF group had significantly higher DDS and DVS than the non-IF group (P < 0.001). CONCLUSIONS The lunches provided in SLS facilities were better in terms of quantity and quality when provided through IF than through non-IF. More systematic foodservice programs should be implemented in SLS facilities, especially in facilities wherein users prepare their own meals.

BACKGROUND/OBJECTIVES: The study was performed to investigate health-related lifestyle, dietary habits, and depression according to exercise frequency to understand complex factors that affect effective health management. Thus, exercise frequency, health-related lifestyle, dietary habits, and depression were evaluated in college students in Seoul and Gyeonggi-do areas. SUBJECTS/METHODS: A survey was conducted on college students, aged 19–29, in Seoul and Gyeonggi-do areas from May 13 to May 31, 2020. A total of 594 questionnaires were collected and 566 (269 from males, 297 from females) were statistically analyzed, except 28 with incomplete responses. Collected data were analyzed using SPSS WIN 21.0 program. RESULTS: The sex distribution of the 3 groups according to exercise frequency was significantly different; the ratio of males in over 3 times/week group was significantly higher than those in 1–2 times/week group and no-exercise group (P < 0.001). The height (P < 0.001), weight (P < 0.001), and body mass index (P < 0.05) were significantly higher in over 3 times/week group compared to no-exercise group. The ratio of subjects who answered ‘good’ or ‘very good’ for subjective health condition was significantly high in the order of ‘over 3 times/week’ group (59.1%), ‘1–2 times/week’ group (34.5%), and ‘no-exercise’ group (25.0%) (P < 0.001). The ratio for meal regularity was high as 56.6% in ‘over 3 times/week’ group and the ratio for irregular meals was significantly higher in ‘no-exercise’ group (67.2%) and ‘1–2 times/week’ group (54.9%) (P < 0.001). Among questions on dietary habits, ‘Eat meat, fish, egg or beans’ (P < 0.01) and ‘Eat fruit’ (P < 0.01) were significantly higher in ‘over 3 times/ week’ group compared to ‘no-exercise’ group. ‘Drink more than 2 liters of water’ (P < 0.001) was 0.70 in ‘over 3 times/week’ group, which was significantly higher than 0.54 in ‘1–2 times/ week’ group and 0.38 in ‘no-exercise’ group. Moderate depression and severe depression that need treatments were significantly lower in ‘over 3 times/week’ group (18.7%) compared to ‘1–2 times/week’ group (26.0%) and ‘no-exercise’ group (29.7%) (P < 0.05). CONCLUSIONS It is considered that combined intervention for exercise habits, proper dietary habits, and depression management is needed for effective health management.

Purpose: For college students, poor eating habits can cause problems with adult health. This study investigated the status of sweet food intake and the degree of stress in college students in the Seoul and Gyeonggi areas to provide a basis for nutrition education by analyzing the relationship between stress and sugar intake. Methods: The subjects were 760 college students, and the survey was conducted using a questionnaire. Statistical analysis for collected data was performed using SPSS (version 21.0). Results: The stress score showed higher stress in female students. Females had more stress in their employment and study-related problems than males. For changes in food intake under stress, the intake was increased greatly in females than in males. For food preference changes before and after stress, males preferred more spicy foods and less salty foods after stress. After stress, females significantly preferred sweeter and spicier foods and less salty, sour, and bitter foods. The intake of sweet foods by stress factors showed that the intake of snacks was higher under the condition of ‘worry, fatigue, and tension’, and the intake of beverages was increased significantly under the condition of ‘anger and aggression’. Conclusion Sweet foods were preferred under stress, and the amount of intake was increased. Education on food selection and nutrition information should be provided to prevent health problems that can be developed by the reckless intake of sweet foods. Active guidance is needed for college students to select the proper snacks instead of nutritionally insufficient foods to relieve stress.

The study examined the perceived health status, dietary habits, and health-related lifestyle habits of middle-aged men and women in Seoul and Gyeonggi-do areas. The survey was conducted on 670 individuals (320 men and, 350 women), aged 40∼64 years, in Seoul and Gyeonggi-do areas. The online and written data were analyzed using the SPSS WIN 25.0 program. Although there was a significant difference in the perceived health status (P＜0.01), there were no significant differences in the subjective stress and the current disease status according to sex. For dietary habits, the scores for fruit intake (P＜0.05), meat and fish intake (P＜0.05), milk and dairy products intake (P＜0.01), and seaweed intake (P＜0.05) were higher in women than men. The scores for three-meal eating (P＜0.05) and water intake (P＜0.01) were higher in men than women. For the health-related habits, alcohol-drinking frequency, daily alcohol consumption, smoking experience, and daily smoking were higher in men than women (P＜0.001). In contrast, caffeinated beverage intake, exercise frequency, and daily smart-phone, computer, and TV using time were similar in both sexes. The meal-eating time was faster in men than women (P＜0.01). For dietary behavior changes, only appetite showed a significant gender difference (P＜0.05). This study provides essential information on the perceived health status, dietary habits, and health-related lifestyle habits in middle-aged men and women. Nevertheless, further research and a practical nutrition program will be needed to solve undesirable dietary habits and improve the health and lifestyle of middle-aged adults according to sex.

Purpose: This study examined the eating-out patterns of Korean infants and school-aged children and compared diet quality. Methods: Data were obtained from the 2016–2018 Korea National Health and Nutrition Examination Survey. The subjects were 306 children aged 3 to 11 years old that ate dinner at restaurants. Percentage energy intakes of 24 food groups were calculated, and cluster analysis was used to identify eating-out patterns. Diet quality was assessed by calculating percentage energy and nutrient intakes using one-third of the 2015 Dietary Reference Intakes for Korean (KDRIs), nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ). Results: Cluster analysis identified 2 eating-out patterns, that is, a ‘rice-centered’ (53%) and a ‘mixed diet’ (47%) pattern. For those with the mixed diet pattern, ratios of carbohydrates, protein, and fat to total calories were 48:20:31, whereas for the rice-centered pattern, ratios were 62:15:21 (p < 0.001). Intakes of energy and most nutrients in the mixed diet pattern were excessive, but the intakes of the most nutrients in the rice-centered pattern were much lower than their KDRIs. MARs were higher for the mixed diet pattern than the rice-centered pattern (0.74 vs. 0.66) (p < 0.001), and INQs for vitamin C (p = 0.007) and calcium (p = 0.018) were lower for the rice-centered pattern, whereas INQ for iron (p = 0.003) was lower for the mixed diet pattern. Conclusion The quality of meals for infants and school-aged children depended on eating-out patterns, but the rice-centered and mixed diet patterns both failed to provide an appropriately balanced meal pattern. The results of this study suggest that healthy menus need to be developed for children in restaurants.
