This study aimed to assess the dietary quality and food habits in children with pervasive developmental disorder (PDD) and to evaluate the relationship between diet quality of children with PDDs and their caregivers' feeding practice and nutritional perceptions. Twenty-one pairs of caregivers and their children with PDD were surveyed. The caregivers completed surveys regarding their children's weight status, food habits, and dietary quality and their food habits, nutritional perceptions, knowledge, and feeding practices. Dietary quality was assessed as mean adequacy ratio, dietary diversity score (DDS), dietary variety score (DVS), and Index of Nutritional Quality (INQ). The children were in the normal ranges of body mass index (BMI) and Röhrer index. Having three times a meal, regular meal time, salty taste of the caregiver were related to those of the children with PDD (β = 0.533, 0.447, and 0.886, respectively; p < 0.05). Child control, food as reward, involvement, pressure, and restriction for the health of the caregiver were positively related to DDS, DVS, and INQ of the children with PDD (p < 0.05). High feeding stress and nutritional knowledge of the caregiver were related to the high BMI of the children with PDD (β = 0.445 and 0.602, respectively; p < 0.05), whereas emotion regulation, encourage balance and variety, and involvement of caregiver were negatively related to BMI (β = −0.426, −0.430, and −0.388, respectively; p < 0.05). In conclusion, food habits of children with PDD were closely related to those of caregiver. To improve nutritional status, more insightful understand will be required by considering their developmental differences in this population.

The dietary behavior of immigrants starts changing upon their arrival in a new country. We evaluated changes in dietary quality of Vietnamese women immigrants in Korea and compared dietary quality with that of Korean women. Fifty-six Vietnamese women immigrants and 56 age-matched Korean women were recruited. Dietary quality were assessed using index of nutritional quality (INQ) and diet quality index-international (DQI-I). Dietary habits were assessed according to 4 dietary behaviors: a prudent, calorie control, dietary fat control, and sodium or salt control diet. DQI-I scores of Vietnamese immigrants decreased after immigration, especially the moderation score, although the variety score increased. Scores were significantly lower than those of Korean subjects (45.1 vs. 64.5; p < 0.001). Vietnamese women immigrants had significantly poorer nutrient balance and calorie intake control, although their fat and sodium control was better than that of Korean woman (p < 0.001). INQs of protein, niacin, phosphorus, iron, zinc were lower in immigrants who had lived longer in Korea than more recent immigrants (p < 0.05). Lower INQs of protein, fiber, vitamin A, B1, B6, C, folate, and phosphorus were related to higher body fat in Vietnamese immigrants (p < 0.05). In conclusion, dietary quality of Vietnamese immigrants decreased after migration, and dietary intake was inadequate compared with that of Korean women. In addition, diet quality of Vietnamese immigrants decreased with length of residence in Korea. There was a negative correlation between diet quality and body fat percent in Vietnamese women immigrants. Findings from this study may help improve diet quality and prevent obesity in Vietnam women immigrants.

Although vitamin C supplements were consumed for health maintenance and fatigue recovery, the effects of high doses of vitamin C supplement remains controversial. Our study performed the effects of 100 mg and 2,000 mg vitamin C supplements on plasma and urinary vitamin C concentration in Korean women. Twenty-four women completed the 4 weeks intervention. Anthropometric data, plasma and urinary vitamin C concentrations, superoxide dismutase activity, thiobarbituric acid reactive substance (TBARS) level, and fatigue severity scale (FSS) were collected, and the statistical analyses compared between- and within-group findings at pre- and post-intervention. Concentrations of vitamin C in plasma and urinary excretion were significantly increased with 100 mg and 2,000 mg of vitamin C supplementation (p < 0.050). TBARS level was decreased significantly with 2,000 mg of vitamin C supplementation (p < 0.050). In addition, FSS was declined significantly in 100 mg of vitamin C supplementation group (p < 0.050). Our result showed that vitamin C supplementation of either 100 mg or 2,000 mg led to an increase in vitamin C concentrations in plasma and vitamin urinary excretion but not statistically significant among groups. TBARS level was decreased in 2,000 mg and FSS was decreased in 100 mg of vitamin C supplementation in Korean women. We suppose that additional clinical trial is needed to examine the effects of vitamin C supplements for a wide range of doses on plasma and urinary vitamin C concentrations in Korean.

We aimed at assessing psychological variables and eating behaviors on quality of diet and life in South Korean women according to their weight status. Socio-psychology, eating behavior, quality of diet and quality of life data were assessed in 114 women (mean age: 34.5 ± 8.09 years). NEO Personality Inventory (NEO-PI-RS) and coping styles questionnaire were used to assess socio-psychology variables, and eating behavior was assessed using the Eating Attitudes Test-26 (EAT-26), Dutch Eating Behavior Questionnaire (DEBQ), and General Food Craving Questionnaire Test (G-FCQ-T). Quality of diet was analyzed by Diet Quality Index-international (DQI-I), and obesity-related quality of life was evaluated using the Korean Obesity-related Quality of life Scale (KOQOL). Significant differences were in the psychological variables and eating behaviors in the obese group than the normal and overweight groups (p < 0.05). The overall score of DQI-I was significantly lower in the obese group than that of their counterparts (p < 0.05). BMI was positively correlated with neuroticism, emotional eating, and obesity-related quality of life, and negatively correlated with diet quality. Neuroticism was positively correlated with emotional eating and food craving. Emotional eating was positively correlated with obesity-related quality of life. In conclusion, women with a higher BMI had significantly more problematic eating behaviors, poor diet quality and quality of life.

Appetite controlling has been an main strategy for regulating food intake and energy balance in obesity treatment. The aim of this study was to examine the effects of drinking tea of the medicinal herbs, fennel and fenugreek, on the subjective appetite in overweight Korean women. The study was conducted using a placebo-controlled, single-blinded, randomized, and 3-way crossover design. Nine healthy women were given fennel tea (FT), fenugreek tea (FGT), or placebo tea (PT). After drinking a given tea, a lunch buffet was provided and then food consumption of subjects was analyzed. Subjective appetite, hunger, fullness, desire to eat, and prospective food consumption were measured at seven independent time point using a visual analog scale (VAS). Mean age of 9 subjects were 49.7 ± 4.5 years and their mean body mass index were 24.6 ± 0.6 kg/m2. There was no significant difference in food consumption in the lunch buffet after drinking each tea; however, with respect to the subjective appetite scale, FGT decreased hunger, led to less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). Similarly, the consumption of FT resulted in decreased hunger, less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). The area under the curve of VAS graph indicated that FGT resulted in a higher feeling of fullness than the PT (p < 0.05). In conclusion, drinking the FT and FGT were significantly effective aid to suppress subjective appetite among overweight women in South Korea.

Poor diet quality is one of strong predictors of subsequent increased mortality in hemodialysis patients. To determine diet quality and to define major problems contributing to poor diet quality in hemodialysis patients, a cross-sectional study was conducted between June 2009 and October 2010. Sixty-three hemodialysis patients (31 men, 32 women; aged 55.3 ± 11.9 years) in stable condition were recruited from the Artificial Kidney Center in Kyung Hee University, Seoul, Korea. Three-day diet records were obtained for dietary assessment. Mean adequacy ratio (MAR) is the average of the ratio of intakes to Dietary Reference Intakes (DRI) for 12 nutrients. Index of nutritional quality (INQ) was determined as the nutritional density per 1,000 kcal of calories. Overall diet quality was evaluated using the Diet Quality Index-International (DQI-I). Statistics were used to determine diet quality, comparing dietary intake to DRI. Dietary calories (21.9 ± 6.7 kcal/kg/day) and protein (0.9 ± 0.3 g/kg/day) were found insufficient in the participants. The overall intake of 12 nutrients appeared to be also inadequate (0.66 ± 0.15), but INQs of overall nutrients, except for folate (0.6) and calcium (0.8), were found relatively adequate (INQ ≥ 1). As a result of diet quality assessment using DQI-I, dietary imbalance and inadequacy were found to be the most problematic in hemodialysis patients. This study suggests that the main reason for insufficient intake of essential nutrients is insufficient calorie intake. Hemodialysis patients should be encouraged to use various food sources to meet their energy requirements as well as satisfy overall balance and nutrient adequacy.

Nutritional status of children with chronic kidney disease (CKD) is important since it affects growth and development. This study was to investigate overall diet quality measured by nutrient intake adequacy, nutrient density, and several dietary habits in children with CKD and its relationship with clinical parameters according to glomerular filtration rate (GFR). Assessment of nutritional status and diet quality was conducted in nineteen children with CKD. Average Z-scores of height, weight and body mass index (BMI) in the participants were less than standard growth rate. Nutritional status, such as Z-scores of height (p < 0.05) and serum total protein (p < 0.05), were significantly lower in the children with GFR < 75 mL/min/1.73 m2 compared to those with GFR ≥ 75 mL/min/1.73 m2. Nutrition adequacy ratio of energy, thiamin, riboflavin, vitamin B6, folate, iron, and zinc and overall diet quality were significantly poorer in the children with GFR < 75 mL/min/1.73 m2. Poorer appetite and avoidance of food were observed in the children with higher blood urea nitrogen (BUN). Intakes of iron, zinc, thiamin, niacin, and vitamin B6 were positively correlated with GFR. Intakes of calcium, potassium and folate were positively correlated with BUN, while protein intakes were negatively correlated. Overall nutrient intakes were inadequate and diet quality was decreased as kidney function was decreased. Dietary habit and appetite were also related with kidney function in this study subjects. Systemic efforts of nutritional intervention are imperative to prevent deteriorating growth and development and improve the nutritional status in children with CKD.

Understanding the relationship between energy nutrients compositions in a diet and appetite-controlling substances is essential for providing sound advice to anyone attempting to control body weight. Appetite is known to be affected by various hormones, ghrelin and peptide tyrosine-tyrosine (PYY), which are related to the compositions of a diet. The purpose of this study was to investigate the effects of compositions of energy nutrients in the diet on the levels of postprandial appetite-related hormones and satiety in healthy adult women. Ten subjects (BMI: 18.5-22.9 kg/m2) were recruited and assigned to three iso-coloric breakfast meals with different compositions of energy nutrients, regular meal (RM, CHO: 60%, Pro: 20%, Fat: 20%), high protein meal (HPM, CHO: 30%, Pro: 50%, Fat: 20%), and high fat meal (HFM, CHO: 30%, Pro: 20%, Fat: 50%). Blood levels of ghrelin, PYY, insulin and leptin and satiety were assessed at baseline, 30, 60, 90, 120, and 180 min following the consumption of each meal. There was no significant difference in the fasting blood hormones among the subjects taking each meals at baseline. Blood levels of ghrelin and insulin changed significantly following the consumption of each meal (p<0.05) over time, however no significant difference was shown between experimental meals until 180 min. Blood levels of PYY and leptin were not changed following the ingestion of each meals. In conclusion, the composition of energy nutrients in a diet had no effect on the postprandial plasma levels of ghrelin, PYY, insulin and leptin as well as satiety in healthy adult women.
