The purpose of this study is to analyze the factors associated with health and diet by nutritional status. The subjects were the children aged 2 to 6. Physicians and nurses measured children's anthropometries and examined their blood and urine. Interviewers questioned children's food habits to their mothers. 24 hour recall was done for children with their mother. The nutritional status was classified to 'underweight', 'normal weight' and 'overweight' by weight for height(median±1 S.D.) of the reference population. The number of subjects in each group(under, normal, over) was 25, 130 and 49. Factors including anthropometry and hemoglobin concentration were not significantly dif ferent by the nutritional status. The birth weight of children was correlated positively to mothers' BMI. Z scores of weight for height were related to the birth weight positively by the analysis of variance. The children of the underweight group used nutritional supplements more frequently than those of normal and overweight group. The nutrient intakes of normal weight group were higher than those of low and overweight group. Particularly, the intakes of energy, carbohydrate and calcium were significantly high among the groups. In terms of number of foods, food groups and dishes consumed per day, the children of the normal weight group ate more diversely than other groups but the differences were not significant. In conclusion, the children of normal weight group had similar characteristics with other groups but had more desirable dietary intakes than other groups in this study. Because the diet of children may be different by the nutritional status, nutrition education for children should be conducted according to the characteristics of each group's diet.

It has been reported frequently that clinical features of gallstone disease in Korean were similarly changing to those of Occidentals. This changing was thought to be due to Westernized lifestyle and dietary patterns in Korean. The purpose of this study was to investigate the nutritional risk factor among patients with gallstone. The subjects of this study were 90 gallstone group with biliary stone as confirmed by cholecystectomy and 111 control group with no biliary stone as confirmed by ultrasonography adjusted according to age and gender. Anthropometric indices and biomarkers were measured and dietary habit as well as nutrient consumption pattern were investigated using a structured checklist of health-related eating behavior and a semi-quantitative food frequency questionnaire. The mean age was higher in GG (gallbladder stone patient group) than CG (control group). The average BMI and WHR (waisthip ratio) tended to be higher than those in CG. WC (waist circumference) and WHR of women in GG were significantly higher than in CG. GG had lower levels in TC (p < 0.01), LDL-C (p < 0.05), and HDL-C (p < 0.05), but higher FBG levels (p < 0.001). GG tended to be associated with lower physical activity and more frequent consumption of meat, meats with high fat and high sugar content food. The consumption levels of fiber (p < 0.05), vitamin C (p < 0.05), calcium (p < 0.01) in GG were significantly lower than in CG. These findings showed that the association with incidence of gallbladder stone and anthrophometric indices and dietary consumption patterns. Further study may be necessary to elucidate the dietary risk factors in the changing patterns of gallstone disease.

Objectives: Acceptability of patients towards obesity treatment program is associated with better weight loss outcomes. The purpose of this study was to review previously published study results of the predictive factors associated with patients' acceptability in obesity treatment. Methods: Authors searched for the articles related to acceptability reported as continuation, attendance and adherence, published from 2011 to 2018 found on Pubmed, Scopus, Research Information Sharing Service, and Koreanstudies Information Service System. A total of 23 articles were finally selected. From the study results, unchangeable and changeable predictors were extracted, and these predictors were examined according to detail categories. Results: Regarding the continuation of the treatment, unchangeable factors such as younger age, lower educational level, male sexuality and lower accessibility to physical activity predicted lower continuation. Furthermore, changeable factors such as early and half weight loss, better accessibility to the treatment and financial incentives for retention predicted higher continuation rate. Greater degree of attendance was predicted by unchangeable factors such as economical affordability, and changeable predictors such as half weight loss and proximity to the clinic. Main factors of adherence to the recommendation were unchangeable predictors such as weight loss experience, and changeable predictors such as more physical activity and appropriate dietary habits. Negative psychological state predicted lower continuation, attendance and adherence rate. Conclusions: Our review results suggest that unchangeable and changeable predictors of acceptability of patients should be carefully examined during treatments of obesity.

This study was conducted to investigate the effect of the differences in nutrient intakes on the onset of eye disease in the ophthalmic disease group vs. the normal group. The analysis method of this study was performed by adjusting age and gender. The daily caloric intake was 1,672.1±26.4 kcal in the ophthalmic disease group which was significantly lower than the 2,041.5±13.6 kcal intake in the normal group (P=0.006). The intake of proteins (P=0.015) and carbohydrates (P=0.000) was significantly lower in the ophthalmic disease group than in the normal group. The incidence of eye diseases was found to decrease by about 0.79 (95% CI: 0.74~0.83) times as the NAR index of protein was increased, followed by 0.79 (95% CI: 0.64~0.98) times with an increase in niacin consumption. In this study, income, BMI, smoking, alcohol consumption, and quality of life were considered as the confounding variables related to eye disease, along with age and gender, but did not lead to show significant results. It was found that the ophthalmic disease group had an unbalanced nutritional intake compared to the normal group. Therefore, we conclude that nutrition education is necessary to ensurebalanced eating habits for management and prevention of degeneration after the onset of eye diseases.

Purpose: In this study, we assessed the intake of nutrients and food groups and analyzed the nutrition quotient of obese children in South Korea. The hypothesis was that dietary quality and nutrient intake are related to the body mass index (BMI) of obese children. Methods: The participants included 48 children (20 boys and 28 girls). Based on the guidelines for the age-for-body mass index provided by the Korean National Growth Charts for children and adolescents, the participants were divided into 3 groups: overweight, BMI ≥ 85th percentile; obese, BMI ≥ 95th percentile; severely obese, BMI ≥ 99th percentile. Results: The energy distribution showed that the carbohydrate ratio was significantly higher in the overweight group (p < 0.01), whereas the fat ratio was significantly higher in the obese and severely obese groups (p < 0.05). Thus, in the overweight and obese groups, the percent body fat was negatively associated with the carbohydrate ratio (p < 0.05) but was positively associated with the fat ratio (p < 0.05). The Dietary Reference Intakes (DRI) data revealed that the intake levels of protein, vitamin B₁, vitamin B₁₂, and sodium were higher in all groups. Intakes of fiber, calcium, potassium, and magnesium were insufficient in all groups, and the DRI percent for protein was significantly higher in the obese and severely obese groups than in the overweight group. No significant differences were obtained in food group patterns or Nutrition Quotient (NQ) scores among the 3 groups. According to the evaluation results by food record and NQ, a significant difference was obtained in the dietary quality of obese children. Conclusion: We conclude that a higher intake of fat enhances weight gain. Based on the study results, we propose that the guidelines should consider the energy distribution of carbohydrate and fat intake to prevent and control obesity among Korean children.

Objectives: Bone health in early adulthood, as individuals approach peak bone mass, plays a critical role in preventing osteoporosis later in life. This study aimed to investigate the associations between lifestyle and dietary factors, anthropometric measurements, and urinary bone resorption markers in young adults. Methods: A cross-sectional study was conducted with 100 healthy Korean adults (50 men and 50 women) in their 20s and early 30s. Bone mineral density (BMD), anthropometric measurements, dietary intake (24-hour recall), and urinary bone resorption indicators (deoxypyridinoline and N-terminal telopeptide of type I collagen) were analyzed. Variables were compared between the osteopenia and osteoporosis groups (OSTEO group: 30% men and 60% women) and the healthy control group. Results: Men in the OSTEO group were significantly taller than those in the control group (P < 0.05). Women in the OSTEO group had significantly lower body weight and body composition (muscle and body fat) than those in the normal group (P < 0.01). Men in the OSTEO group had a significantly higher intake of animal calcium (Ca) than those in the normal group (P < 0.05). Women in the OSTEO group had significantly higher dietary fiber, vitamin A, Ca, plant Ca, and potassium intake than did those in the normal group (P < 0.05). There were no significant differences in caffeinated beverage consumption, eating habits, or urinary bone resorption indicators between the OSTEO and control groups of either sex. Conclusions: In our study of young South Korean adults, we observed low bone density levels, with particularly low BMD in taller men and underweight women. We found a higher nutrient intake in the OSTEO group, indicating the possibility of reverse causality, a phenomenon often found in cross-sectional studies. Therefore, there is a need to further elucidate dietary factors related to osteoporosis in young adults through prospective cohort studies involving a larger population.

Background: This study aimed to examine the impact of chronotype on depressive symptoms and explore the mediating effects of sleep quality, pre-sleep cognitive arousal, and social jetlag in a sample of wage earners. Methods: A total of 3,917 waged workers were surveyed online in July 2022. Logistic regression and mediation analysis were used to assess the relationship between chronotype (morningness, intermediate, and eveningness) and depressive symptoms (Patient Health Questionnaire ≥ 5), and the mediating effects of Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Pre-Sleep Arousal Scale (PSAS). All analyses were adjusted for age, education level, income level, marital status, coffee consumption, alcohol consumption, physical activity, occupation, employment status, and working hours to calculate odds ratios (ORs). Results: The chronotypes of all the participants were divided into morningness (4.7%), intermediate (93.5%), and eveningness (1.8%). Multiple logistic regression analysis showed an increased risk of depression in the eveningness chronotype (OR: 2.96; 95% confidence interval [CI]: 1.51, 5.86). Regarding the mediation analysis, ISI mediated 28.44% (95% CI: 16.39-40.5), PSQI for 31.25% (95% CI: 19.36, 43.15), and PSAS-Cognitive Score (PSAS-C) for 23.58% (95% CI: 10.66, 36.50) of the association between chronotype and depressive symptoms. However, social jetlag did not significantly mediate this relationship. (percentage mediated = 0.75%, 95% CI: -3.88, 5.39) Conclusions: Evening chronotypes exhibit an increased risk of depressive symptoms, which ISI, PSQI, and PSAS-C partially mediated. This suggests that interventions to improve sleep quality and maintain adequate sleep habits may effectively prevent and treat depression in employees with an eveningness chronotype.

Purpose: Dietary habits are strongly related to the symptoms of people with irritable bowel syndrome (IBS). Therefore, personalized nutrition management can help reduce symptoms and improve the quality of life of people with IBS. This study assessed the effectiveness of a personalized web-based nutrition management based on the types of food that trigger IBS symptoms. Methods: Sixty Korean adults with IBS according to Rome IV criteria in their 20s and 30s were enrolled in this study. The data from the final 49 patients who completed a three-month personalized nutrition intervention were analyzed. The general information, anthropometry, dietary intake survey, and gut microbiota were examined pre and post-intervention. The gut microbiota analysis included the relative abundance and the Shannon index. The food intake was recorded for two days for personalized nutrition education, followed by three months of personalized nutrition intervention. Statistical analysis was performed using the Wilcoxon signed-rank test in SPSS 26.0, with the significance set to p < 0.05. Results: The relative abundance of the gut microbiota changed after personalized nutrition management, with a significant decrease in the presence of Veillonella (p = 0.048). Furthermore, when the gut microbiota was analyzed according to the type of food that triggers symptoms, the diversity was increased significantly in the high fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) type (p = 0.031) and FODMAPs-containing gluten-type personalized nutrition intervention types (p < 0.001). Conclusions: Gut microbial diversity and gut microbiota distribution changed after using web-based personalized nutrition management. Hence, personalized nutrition management that considers trigger foods may improve IBS symptoms.

Objectives The purpose of this study was to compare sleep quality and chronotype by Sasang constitution and examine the relationship with nutritional status. Methods This study used 672 follow-up data from the Korean Medicine Daejeon Citizen Cohort study (KDCC). Demographic, Sasang constitution, sleep quality, chronotype, and nutritional status evaluation were conducted based on questionnaires. Multiple linear regression analysis was used to confirm the relationship between sleep quality and chronotype according to Sasang constitution and nutritional status. Results The relationship between sleep quality and chronotype by Sasang constitution and nutritional status is that Taeeum nutritional index is related to sleep quality (adj. B = -0.46, 95% CI = -0.79 ~ -0.12) and chronotype (adj. B = 0.38, 95% CI = 0.24 ~ 0.52), and Soeum and Soyang showed an association between nutritional indices only in chronotype (adj. B = 0.43, 95% CI = 0.23 ~ 0.63 in SE, adj. B = 0.55, 95% CI = 0.38 to 0.73 in SY). Conclusions This study confirmed the relationship between sleep quality and chronotype and healthy eating habits. For a balanced nutritional status, overall sleep management is necessary. Based on the results of this study, we intend to use it as basic data on the impact of the relationship between nutritional status and chronotype by Sasang constitution on health.
