The purpose of this study was to investigate the association between dietary macronutrient intakes and prevalence of metabolic syndrome (MetS) in Korean adults. Data were obtained from the Korean National Health and Nutrition Examination Survey (2013-2017), and a total of 11,600 Korean adults (4,918 men, 6,682 women) aged 50 years and older were analyzed. The daily intakes and percentages of energy from carbohydrates or fat in men or women with MetS were significantly lower than in normal subjects, respectively. High carbohydrate or fat percentages were negatively associated with MetS based on adjusted odds ratios (OR) of 0.804 in men (p=0.034) and 0.820 in women (p=0.045), respectively. A high percentage of energy from carbohydrates was positively associated with reduced waist circumference, diastolic blood pressure, triglyceride and high-density lipoprotein (HDL) cholesterol in men. On the other hand, a high percentage of energy from fat was positively related with elevated HDL cholesterol and reduced triglycerides in women. In conclusion, our study indicates that high carbohydrate or fat intake is associated with risk of MetS in Korean men or women aged 50 years and older, respectively. Further prospective studies are necessary to elucidate the association between macronutrient intakes and MetS among Korean adults according to age.

BACKGROUND/OBJECTIVES: Since gain or loss of skeletal muscle mass is a gradual event and occurs due to a combination of lifestyle factors, assessment of dietary factors related to skeletal muscle is complicated. The aim of this study was to investigate the changes in total energy intake according to the level of skeletal muscle mass. SUBJECTS/METHODS: A total of 8,165 subjects ${\geq}30years$ of age from the Korean National Health and Nutrition Examination Surveys (KNHANES) 2008-2011 were included in the analysis, and multivariate-adjusted regression analyses were performed to analyze the association of the quartiles of sarcopenia index (SI) with energy intake of the study population after adjusting for age and metabolic parameters. RESULTS: The increase in SI quartile was in proportion to the gradual decrease in systemic lipids and the anthropometric measurement of fat accumulation (P < 0.001). Subjects in higher SI quartiles tended to consume more total energy and energy-producing nutrients than those in lower quartiles (P < 0.001). After age, body weight, alcohol consumption, and metabolic parameters were adjusted in the analysis, total energy intake gradually increased according to the increase in SI quartile, and the association between total energy intake and SI was more pronounced in men. However, the risk (odd ratio) of having a low SI was not affected by any single macronutrient intake. CONCLUSION: In this study, total energy intake was positively associated with SI and relative skeletal mass in both men and women. However, no significant association or a weak association was observed between any single macronutrient intake and skeletal muscle mass. The data indicated that acquiring more energy intake within the normal range of energy consumption may help to maintain skeletal muscle mass.

Objectives: The associations between the eating behavior and energy and macronutrient intake from meals and snacks consumed during different times of the day across the menstrual cycle were investigated in 74 healthy female college students. Methods: A 9-day food record was collected during the last 3 days before menstrual onset (phase 1) and the first 3 days after menstrual onset (phase 2) and from the 4th to the 6th day after menstrual onset (phase 3), respectively. Anthropometry was assessed and eating behaviors were measured using the Dutch Eating Behavior Questionnaire (DEBQ). Results: External eating was the most prevalent type of eating behavior, followed by restrained eating and emotional eating. Restrained eating was positively associated with energy, carbohydrate and lipid intake at the breakfast and midmorning snack during phase 3. However, emotional eating was also positively related to energy and macronutrient intake at the dinner and after-dinner snack during phase 1 and phase 3, with higher level detected in the phase 1. The association of emotional eating with the snack consumption was highest in phase 1. External eating was positively associated with energy and macronutrient intakes at the dinner and after-dinner snack across the three phases, the highest level being phase 1. In addition, restrained eating was positively associated with the weight, body mass index(BMI), fat mass, waist and hip girth of the subjects. Conclusions: Eating behaviors varied with regard to meals and snacks consumed during different times of the day across the three menstrual phases. Dinner and afterdinner snack consumption in premenstrual phase could be considered as a time when women are more prone to overconsumption and uncontrolled eating.

The study was conducted to assess the association or physical activity, television watching and energy intake with body fat in 514 adolescents(218 boys, 296 girls) aged 14-17 years. Comparison of the weight status evaluated according to some indicators based on weight and stature was made. The quantitative food frequency was used to determine intakes of total energy and energy from each macronutrient. Television-watching time was used as an index of inactivity and time spent performing extra-curricular physical exercise or playing was used a index of activity, BMI(body mass index) was used as index of body fat. Weight status varied by the indicators used. Using BMI, Broca and Rohrer index, 54-59% of boys and 38-57% of girls were underweight decreased(23% of boys and 26% of girls) and the of overweight increased (9.3% of boys and 7.8% girls), when adolescents whose BMI are<=15th percentiles for age and sex, and >= 85th percentiles of standard growth charts of Korean Children and aldosescents(1998) were classified as underweight and overweight, respectively, Girls tended to get fatter compared to boys who showed greater skeletal development. There were no significant correlations between BMI and total energy intake, energy intakes from macronutrient and physical activity level. These lack of association seems to be related to indication that BMI reflects total body mass rather than fatness. Mpreover, the effect of growth may interact with diet intake or physical activity level. Although BMI was not related to physical activity, television-watching time was negatively correlated with physical activity. Television-watching time was positiviely correlated with energy intake in girls. In adolescents, criteria for weigh status based on weight and stature must be age- and sex-specific in that weight status varied by indicators whether gender and higher were taken into consideration or not. If follows that each hourly increment of television watching may be related to fatness of adolescents, because hours certainly reduce the opportunity to be active and increase th energy intake.(Korean J Nutrition 34(1):39-47, 2001)

Underreporting patterns by the level of obesity have not been fully assessed yet. The purpose of this study was to examine the differential underreporting patterns on cardiovascular risk factor, macronutrient, and food group intakes by the level of Body Mass Index (BMI). We analyzed cross-sectional baseline nutritional survey data from the population-based longitudinal study, the Healthy Women Study (HWS) cohort. Study subjects included 538 healthy premenopausal women participating in the HWS. Nutrient and food group intakes were assessed by the one-day 24-hour dietary recall and a semi-quantitative food frequency questionnaire, respectively. The ratio of reported energy intake (EI) to estimated basal metabolic rate (BMR) was used as a measure of relative energy reporting status and categorized into tertiles. Overweight group ($BMI{\geq}25kg/m^2$) had a higher ratio of EI to BMR (EI/BMR) than normal weight group ($BMI<25kg/m^2$). Normal weight and overweight groups showed similar patterns in cardiovascular risk factors, nutrient intake, and food group intake by the EI/BMR. Fat and saturated fat intakes as a nutrient density were positively associated with the EI/BMR. Proportion of women who reported higher consumption (${\geq}4\;times/wk$) of sugar/candy, cream and red meat groups was greater in higher tertiles of the EI/BMR in both BMI groups. Our findings suggest similar patterns of underreporting of cardiovascular risk factors, and macronutrient and food group intakes in both normal and overweight women.

The purpose of this study was to evaluate nutrient and food intake status and dietary, quality according to obesity based on nutrient and food group intake, in female university students. Surveys were conducted using questionnaires and 3 days, dietary record in 360 female university students residing in Seoul. The subjects were divided into two groups by percent of body fat: an overweight group(percent of body fat more than 23%, n=249) and normal group(percent of body fat below 23%, n=111). The overweight group had a larger proportion of subjects who binged compared to the normal group. There was no significant difference in energy intake between the two groups. The densities of plant calcium and dietary fiber in the overweight group were significantly lower than those of the normal group. However, animal fat density was significantly higher in overweight subjects. The Korean's dietary diversity score(KDDS) of the overweight group was 4.65, and that of the normal group was 4.67, indicating no significant difference. There was no significant difference of DQI-I between the overweight group(50.8) and normal group(51.1). However, the macronutrient ratio score was significantly lower in the overweight group. These results indicate that overweight female college students may have improper dietary habits, and have lower overall balance aspect macronutrient ratios.

The aim of this study was to provide descriptive information on meal and snack patterns and to investigate snacks in relation to energy intake and food choice according to the meal patterns of employed people in Korea. 683 employed people (292 males, 391 females) were interviewed to collect one day dietary data by using 24-h dietary recall. A recorded day was divided into 3 meal and 3 snack periods by the respondent's criteria and the time of consumption. To analyze the eating pattern participants were divided as the more frequent snack eaters (MFSE) and the less frequent snack eaters (LFSE). They were also categorized into 6 groups according to the frequency of all eating occasions. The common meal pattern in nearly half of the subjects (47.6%) was composed of three meals plus one or two snacks per day. A trend of an increasing the number of snacks in between main meals emerges, although the conventional meal pattern is still retained in most employed Korean adults. Women, aged 30-39, and urban residents, had a higher number of being MFSE than LFSE. Increasing eating occasions was associated with higher energy, protein, and carbohydrate intakes, with the exception of fat intakes. 16.8% of the total daily energy intake came from snack consumption, while the 3 main meals contributed 83.2%. Energy and macronutrient intakes from snacks in the MFSE were significantly higher than the LFSE. Instant coffee was the most popular snack in the morning and afternoon, whereas heavy snacks and alcohol were more frequently consumed by both of the meal skipper groups ($\leq$2M+2,3S and $\leq$2M+0,1S) in the evening. In conclusion, meal pattern is changing to reflect an increase of more snacks between the three main meals. Meal and snack patterns may be markers for the energy and macronutrient intakes of employed people in Korea.

Purpose: The purpose of this study was to analyze the dietary intake of Korean adults with atopic dermatitis (AD) to determine whether the risk of developing AD was related to their diet. Methods: Among the participants in the 7th National Health and Nutrition Survey (2016 to 2018), 10,571 adults aged 19-64 were divided into AD (AD group, n = 366) and control groups (non-AD group, n = 10,205) to compare and analyze their nutrient intake status and Korean Healthy Eating Index (KHEI) score. Depending on the prevalence of AD, the nutrient intake, nutrient intake per 1,000 kcal, acceptable macronutrient distribution range, and KHEI score were tested for significance by correcting for age, sex, body mass index, education, marriage, occupation, residence area, physical activity, and energy intake variables that were derived for confounding factors. Results: The acceptable macronutrient distribution range for protein was lower in the AD group than in the non-AD group. Comparing the nutrient intake per 1,000 kcal, the intakes of protein, phosphorus, iron, and potassium of the AD group were significantly lower than those of the non-AD group. In the KHEI, the scores of total vegetables, vegetables excluding kimchi and pickles, meat, fish, eggs, and legumes of the AD group were significantly lower than those of the non-AD group. In addition, as these food intake scores increased, the risk of AD significantly decreased. Conclusion: In conclusion, adult AD patients had low intakes of vegetables, meat, fish, eggs, and legumes, and it was confirmed that high intakes of these foods may be associated with low AD risk. Therefore, we suggest that an adequate intake of vegetables and foods containing protein would be necessary for the management and treatment of AD in adults.

The aim of this study was to investigate the relationships among energy intakes, macronutrient intakes, macronutrient compositions, anthropometric and biochemical variables in natural environment of free-living female college students. The daily energy and macronutricnt intakes were analyzed by means of 3- week dictary records. The waist circumference and insulin level were best anthropometric and bio-chemical correlates with the energy, carbohydrate and protein intakes respectively. However, there were no relationships between waist circumference and insulin verse macronutrient compositions that macro-nutrient intakes were expressed as by the percentage of daily encrgy intakes. There were no relationships between BWI, weight, perccnt body fat and fat mass vs. energy and macronutrient intakes. However, BMI was positively related to the percentage of energy from fat and inversely related to the percentage of energy from carbohydrate in their habitual diet. Triglyceride was negatively correlated to the per-centage of energy from fat and fat intakes. Significant positive correlation was also observed bctween the percentage of energy from protein and HSL-cholcsterol.
