Background Complication rates after flap coverage for pressure ulcers have been high historically. These patients have multiple risk factors associated with poor wound healing and complications including marginal nutritional status, prolonged immobilization, and a high comorbidities index. This study utilizes the National Surgical Quality Improvement Program (NSQIP) to examine perioperative outcomes of flap coverage for pressure ulcers. Methods Data from the NSQIP database (2005-2015) for patient undergoing flap coverage for pressure ulcers was identified. Demographic, perioperative information, and complications were reviewed. One-way analysis of variance and Pearson chi-square were used to assess differences for continuous variables and nominal variables, respectively. Multivariate logistic regression was performed to identify independent risk factors for complications. Results There were 755 cases identified: 365 (48.3%) sacral ulcers, 321 (42.5%) ischial ulcers, and 69 (9.1%) trochanteric ulcers. Most patients were older male, with some degree of dependency, neurosensory impairment, high functional comorbidities score, and American Society of Anesthesiologists class 3 or above. The sacral ulcer group had the highest incidence of septic shock and bleeding, while the trochanteric ulcer group had the highest incidence of superficial surgical site infection. There was an overall complication rate of 25% at 30-day follow-up. There was no statistical difference in overall complication among groups. Total operating time, diabetes, and non-elective case were independent risk factors for overall complications. Conclusions Despite patients with poor baseline functional status, flap coverage for pressure ulcer patients is safe with acceptable postoperative complications. This type of treatment should be considered for properly selected patients.

This study was conducted to assess diet-related health appraisal for cardiometabolic diseases of the college students in Gyeonggi-do. The survey data obtained by 21 questionnaire(6 general characteristics and 15 food behaviors) given to 90 students, 41 males and 49 females. The average age of the subjects was 22.2 years old for the male students and 20.9 years old for the female students(p<0.001). Among the subjects, 35 males and 47 females' height, weight and percentage of body fat were measured using bioelectrical impedance(Inbody 720). The average height, weight, Body Mass Index and percent body fat of the subjects were 175.7cm, 69.5kg, 22.4 and 16.9% for males and 162.0cm, 53.5kg, 20.4 and 27.7% for females, respectively (p<0.001). Male students had a higher prevalence of smoking compared with female students(p<0.001). Females had higher intake frequency of fruits than males(p<0.05). Males had higher intake frequency of fishes than females(p<0.05). Male students had higher number of side dishes at mealtime compared with female students. There were no difference between the sexes in intake frequency of dairy, ramyeon, rice with whole grain, 3-layered pork belly, processed meat, soft drinks, soy products and fast food. Also, there were no difference between sexes in number of vegetables per day, frequency of eating out, prevalence of eating kimchi at every meal. Cardiometabolic risks were calculated by 'Diet-related health risk appraisal'. Male students had higher cardiometabolic risks(hypertension, hyperlipidemia, diabetes, obesity, abdominal obesity) than female students(p<0.001). Appropriate nutritional education for college male students may help to prevent cardiometabolic diseases in the future.

Purpose : Several studies suggest that smoking and vitamin D level is a risk factor of metabolic syndrome. The objective of this study is to evaluate the association between smoking status, vitamin D levels and the Korean adult male and female metabolic syndrome. Methods : We assessed 3796 participants aged 19 years and older from the Korean National Health and Nutritional Examination Survey 2013, 2014. Smoking statuses were collected from self-reported questionnaires. Subjects were divided into three categories: non-smokers, former smokers, and current smokers. Vitamin D was tested by Radioimmunoassay method and the value of serum 25-hydroxyvitamin D, which is an index of vitamin D status in the body, was used. The diagnosis of metabolic syndrome was made using criteria modified NCEP-ATP III. Logistic regression analysis was used to calculate odds ratios between smoking status, vitamin D levels, and metabolic syndrome. Results : The overall prevalence of metabolic syndrome was 23.0 % in men and 15.4 % in women. After adjusting for smoking, the odds ratio for men's metabolic syndrome in current smokers was 1.77 (95 % CI, 1.30~2.41), while for former smokers OR was 1.63 (95 % CI, 1.15~2.31) compared with nonsmokers. After adjustment vitamin D, the odds ratio for women's metabolic syndrome in vitamin D deficiency was 1.44 (95 % CI, 1.11~1.87) compared with normal. Conclusion : Smoking status was associated with an increased risk of metabolic syndrome in Korean adult males and decreased vitamin D level was associated with an increased risk of metabolic syndrome in Korean adult females.

The purpose of this study was to identify the effect of nutrition related factors on mortality risk among community-residing older adults in Korea. We analyzed data from 8,532 older adults who took part in the 2008 living profiles of older people survey and 2011 death mortality data. According to Cox regression analysis, male (Hazard Ratio [HR], 2.03; 95% Confidence Interval [CI], 1.74~2.37), diabetes mellitus (HR, 1.35; 95% CI, 1.12~1.64), underweighted (HR, 2.68; 95% CI, 2.16~3.31), dysphagia (HR, 1.23; 95% CI, 1.02~1.47), chewing ability (HR, 1.33; 95% CI, 1.11~1.59), and undernutrition (HR, 1.47; 95% CI, 1.23~1.75) significantly affected mortality risk. Systematic nutrition support programs should be developed to decrease the mortality among Korean older adults.

Objectives: Dental caries and periodontitis are major oral bacterial infections associated with dental plaque. Infection and inflammation play a role in carcinogenesis, and a significant link has been found between some highly prevalent oral and dental diseases and some types of cancer. Therefore, the aim of this study was to evaluate the relationship between cancer and oral health among Korean adults. Methods: Data from the 6th Korea National Health and Nutrition Examination Survey were used to analyze the incidence of cancer according to oral health. Demographic and socioeconomic statuses and oral behavior of the participants was analyzed using complex chi-square tests. Logistic regression was used to analyze the relationship between a high DMFT index and cancer by calculating the 95% confidence intervals. Results: In total, 6,450 case-control subjects were included. Significant difference was observed in the DMFT index, but not in periodontal diseases, between the cases and controls. The odds ratio for cancer was 1.80 (95% confidence interval: 1.18 to 2.73) in the high-risk group. However, no significant difference was observed after adjusting for age, education level, and income. Conclusions: The results provide potential evidence of a significant association between cancer and oral disease.

Purpose: This study examined the association of the type and frequency of coffee consumption with the health-related quality of life and metabolic bio-markers in adult men and women from the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 11,201 subjects (4,483 men and 6,718 women) were classified according to the type of coffee consumption (non-coffee, black coffee, 3-in-1 coffee) and type and frequency of coffee consumption (non-coffee, ${\leq}2$ times/day of black coffee, > 2 times/day of black coffee, ${\leq}2$ times/day of 3-in-1 coffee, > 2 times/day of 3-in-1 coffee) using food frequency questionnaires. Dietary nutrient intake data were assessed using food frequency questionnaires. The health-related quality of life was measured using the EuroQol-5 dimension (EQ-5D) and EQ-5D index score. Data on metabolic bio-markers were obtained from a health examination. Results: Among men and women, the proportion of subjects with an energy intake below the estimated energy requirement (EER) was lower among the 3-in-1 coffee consumption group, and the proportion of subjects with iron intakes below the estimated average requirements (EAR) was lower among the 3-in-1 coffee consumption group. Women (OR: 0.810, 95% CI: 0.657 ~ 0.998) with the ${\leq}2$ times/day of 3-in-1 coffee had a lower risk of impaired health-related quality of life (lowest 20% level in the EQ-5D score) compared to the non-coffee consumers after a multivariable adjustment. In both men and women, the type and frequency of coffee consumption was not associated with metabolic bio-markers risk after multivariable adjustment. Conclusion: These results suggest that 3-in-1 coffee consumption may be associated with a lower risk of impaired health-related quality of life and may not be associated with the metabolic bio-markers risk in adult men and women.

Purpose: This study was undertaken to evaluate the health, nutritional status and metabolic syndrome risk according to the dietary pattern of adult single-person households, using information obtained from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: Data were collected from the 2013-2016 KNHANES, of adults aged 19-64 years, belonging to single-person households. Based on cluster analysis, the dietary patterns of subjects were classified into three groups. The dietary behavior factors, health-related factors, nutritional status, and prevalence of metabolic syndrome obtained from KNHANES questionnaires were compared according to the individual dietary pattern. The nutrient intake data of the subjects were calculated using the semi-food frequency questionnaire. Moreover, blood and physical measurement data of the subjects were analyzed to obtain the prevalence of metabolic syndromes. Results: The major dietary intakes of subjects were classified as 'Rice and kimchi', 'Mixed', and 'Milk·dairy products and fruits' patterns. Characteristics of subjects based on their dietary pattern, gender, age, and education level were significantly different. The 'Milk and fruits' pattern showed low frequency of skipping breakfast and eating out, and had higher intake of dietary supplements. Frequency of alcohol intake and smoking rates were highest in the 'Mixed' pattern. Maximum nutrient intake of fat, vitamin A, riboflavin, vitamin C, niacin, calcium, phosphorus, and potassium was obtained in the 'Milk·dairy products and fruits' pattern. According to dietary patterns adjusted for age and gender, the risk of metabolic syndrome was 0.380 times lower in the 'Milk·dairy products and fruit' pattern than in the 'Rice and kimchi' pattern. However, when adjusted for other confounding factors, no significant difference was obtained between dietary patterns for metabolic syndrome risk. Conclusion: These results indicate that the health and nutritional status of a single-person household is possibly affected by the dietary intake of subjects.

Purpose: The present study examined the associations of Korean Food-based Index of Dietary Inflammatory Potential (FBDI) scores with the prevalence of diabetes and hemoglobin A1c (HbA1c) level of diabetes patients in Korean adults. Methods: The Korean Genome and Epidemiology Study (KoGES) Health Examinee baseline data, collected between 2004 and 2013 and followed up between 2012 and 2016, were used in our study. A total 56,391 participants including diabetes (n = 5,733) and non-diabetes (n = 50,658) were analyzed. The subjects were classified into quartiles of FBDI scores using the semi-quantitative food-frequency questionnaire developed for KoGES. The prevalence rate of diabetes under FBDI scores was assessed by Cox proportional risk models and the severity of the diabetes was analyzed by multiple regression analysis. Results: There were 775 incident cases of diabetes after a mean follow-up of 3.97 years. There was no statistically significant association between FBDI scores and incidence of diabetes. Among diabetes patients at baseline, FBDI scores were related to the risk of progression of diabetes which was represented by greater than 9% HbA1c (Q1 vs. Q4; odds ratio, 1.562 [95% confidence intervals, 1.13-2.15]; p for trend = 0.007). The stratified analysis showed a stronger association in females, irregular exercise group, and higher body mass index group. Conclusion: These results suggest that a pro-inflammatory diet is not associated with the incidence of diabetes but is related to the HbA1c level of diabetes patients. Thus, further longitudinal studies with longer periods are required to determine a relationship between dietary inflammatory index and diabetes in Korea.

Purpose: The aim of this study was to determine an appropriate energy level of breakfast with less risk of chronic disease for Korean adults. Methods: Using data from the 2007~2009 Korean National Health & Nutrition Examination Survey, from a total of 12,238 adults aged 19~64, the final 7,769 subjects were analyzed except subjects who were undergoing treatment for cancer or metabolic disorder. According to the percent of breakfast energy intake versus their estimated energy requirement (EER), the subjects were divided into four groups: < 10% (very low, VL), 10~20% (low, L), 20~30% (moderate, M), ${\geq}30%$ (sufficient, S). All data were analyzed on the metabolic risk and nutritional state after application of weighted value and adjustment of sex, age, residential area, income, education, job or jobless, and energy intake using a general linear model or logistic regression. Results: The subjects of group S were 16.9% of total subjects, group M 39.2%, group L 37.6%, and group VL 6.3%. The VL group included more male subjects, younger-aged (19 to 40 years), urban residents, higher income, higher education, and fewer breakfasts eaters together with family members. Among the 4 groups, the VL group showed the highest waist circumference, while the S group showed the lowest waist circumference, body mass index, and serum total cholesterol. The groups of VL and L with lower intake of breakfast energy showed high percent of energy from protein and fat, and low percent of energy from carbohydrate. With the increase of breakfast energy level, intake of energy, most nutrients and food groups increased, and the percentage of subjects consuming nutrients below EAR decreased. The VL group showed relatively higher intake of snacks, sugar, meat and eggs, oil, and seasonings, and the lowest intake of vegetable. Risk of obesity by waist circumference was highest in the VL group by 1.90 times of the S group and the same trend was shown in obesity by BMI. Risk of dyslipidemia by serum total cholesterol was 1.84 times higher in the VL group compared to the S group. Risk of diabetes by Glu-FBS (fasting blood sugar) was 1.57 times higher in the VL group compared to the S group. Conclusion: The results indicate that higher breakfast energy level is positively related to lower metabolic risk and more desirable nutritional state in Korean adults. Therefore, breakfast energy intake more than 30% of their own EER would be highly recommended for Korean adults.

The objective of this study was to investigate nutritional status of middle aged Korean men exhibiting impaired glucose tolerance (IGT) and identify the risk factors related to IGT Data were collected from 163 men with a fasting blood glucose level from 115 to 139mg/dl(high blood glucose group: HBG) and 170 men with a normal fasting blood glucose level(control) aged from 40 to 59 years in both groups. Weight, body mass index(BMI) and percent body fat were significantly higher in high blood glucose(HBG) group than those of control group. Age, weight, BMI, percent body fat were positively related to blood glucose. There were no differences in exercise, smoking and family history of diabetes between two groups. Frequency of fat eating and overeating of HBG were higher than those of control group but frequency of sweet snacks intake of HBG was lower than that of control group. There was no difference in daily total energy intake in two groups. Total and supper energy intakes were positively associated with blood glucose. Percent energy intake of alcohol was significantly higher in HBG group and positively related to blood glucose, however there were no difference in daily intake of nutrients in two groups. Alcohol intake was positively related to BMI, but after adjusting BMI, there was no correlation between alcohol intake and blood glucose. Serum total cholesterol and triglyceride were significantly higher in HBG group than those of control group. Serum total cholesterol i,nd triglyceride were positively related to blood glucose and high density lipoprotein cholesterol was negatively associated with blood glucose. After adjusting BMI, serum triglyceride was positively related to blood glucose. In conclusion, weight, BMI, percent body fat and blood total cholesterol, low density lipoprotein cholesterol and triglyceride levels were positively related to blood glucose level of middle aged Korean men exhibiting impaired glucose tolerance. Their eating habits exhibited higher frequency of overeating, fast eating, high energy intakes of supper. (Korean J Nutrition 33(1) : 59-67, 2000)
