BACKGROUND/OBJECTIVES: In Argentina, obesity prevalence rose from 14.6% in 2005 to 20.8% in 2013. Although the number of studies on noncommunicable diseases and dietary patterns as a unique dietary exposure measure has increased, information on this topic remains scarce in developing countries. This is the first population-based study investigating the association between diet and obesity using a dietary pattern approach in Argentina. We aimed (a) to identify current dietary patterns of the population of $C{\acute{o}}rdoba$ city, (b) to investigate its association with obesity prevalence, and (c) to identify and describe dietary patterns from the subgroup of people with obesity. SUBJECTS/METHODS: The $C{\acute{o}}rdoba$ Obesity and Diet Study (CODIES) was conducted in $C{\acute{o}}rdoba$ city by using a random sample of n = 4,327 subjects between 2005 and 2012. Empirically derived dietary patterns were identified through principal component factor analysis. A multiple logistic regression analysis was used to investigate the association of dietary patterns with obesity. RESULTS: Four dietary patterns were identified, called "Starchy-Sugar", "Prudent", "Western", and "Sugary drinks". High scores for the "Western" pattern (with strongest factor loading on meats/eggs, processed meats, and alcohol) showed a positive association with obesity (OR: 1.33, 95% CI: 1.06-1.67, for third versus first tertile of factor score). "Meats/Cheeses" and "Snacks/Alcohol" patterns emerged in people with obesity. CONCLUSIONS: The findings suggest that high adherence to the "Western" pattern promoted obesity in this urban population. In addition, people with obesity showed characteristic dietary patterns that differ from those identified in the overall population.
The purpose of this study was to investigate the gene profiles that were up- or down-regulated in the livers of high-fat diet-induced obese mice and $db_-/db_-$ mice with deficient leptin receptor. C57/BL6 normal mice and $db_-/db_-$ mice, respectively, were divided into two groups and fed a standard or high-fat diet for four weeks. Liver weight was unchanged in the normal mice but the high-fat diet led to a 10% weight increase in the $db_-/db_-$mice. Adipose tissue mass increased by about 88% in the normal mice that were fed a high-fat diet and by about 17% in the $db_-/db_-$mice on the high-fat diet. In terms of serum lipids, total cholesterol significantly increased in mice on the high-fat diet. Microarray analysis was carried out using total RNA isolated from the livers of standard or high-fat diet-fed mice of the normal and $db_-/db_-$ strains. The change of gene expression was confirmed by RT-PCR. About 1.6% and 6.8% of total genes, respectively, showed different expression patterns in the normal mice fed the high-fat diet and $db_-/db_-$ mice. As a result of microarray, many genes involved in metabolism and signal pathways were shown to have different expression patterns. Expression of Mgst3 gene increased in the livers of normal and $db_-/db_-$ mice that were fed a high-fat diet. Wnt7b and Ptk9l were down-regulated in the livers of the normal mice and $db_-/db_-$ mice that were fed a high-fat diet. In conclusion, a high-fat diet induced obesity and affected gene expression involved in metabolism and signal pathway.

The study analyzed the lipid patterns and fatty acid compositions of serum and liver tissues in groups of Sparague-Dawley rats. Some of the groups were fed with an basal diet, which contained com oil (C), grape seed oil (GSO), or perilla oil (P), and the others were fed with a high fat diet, which had cholesterol (1%) and lard (10%) mixed with corn oil (CHF), grape seed oil (GSHF), or perilla oil (PHF). The amount of dietary intake was higher for the basal diet groups than the high fat diet groups. And diet efficiency was significantly low in the group of rats fed with the basal diet mixed with perilla oil. From the analysis of the serum lipid patterns, a significant decrease in total lipid concentration was observed in the group of rats fed on the basal diet mixed with perilla oil and the high fat diet group. The levels of triglyceride and phospholipid were significantly low in the basal diet group when perilla oil or grape seed oil was involved. The ordinary diet groups showed significantly higher in HDL-C than the high fat diet groups. There was no significant difference among the basal diet groups, whether the diet was mixed with grape seed oil, perilla oil, or com oil. However, a significant increase in HDL-C was observed in the group of rats fed with the high fat diet containing perilla oil. For LDL-C, there was a significant difference between the high fat diet groups and the basal diet groups. LDL-C was especially low in the group of rats fed with the high fat diet to which perilla oil was added, and the grape seed-added high fat diet group showed a decreasing tendency in LDL-C. The content of total fat, total cholesterol, and triglyceride was the lowest in the group of rats fed with the perilla oil-containing basal diet, and this group was followed in order by the grape seed oil-containing diet group and com oil-containing diet group. In the analysis of the fatty-acid composition in liver tissue, the high fat diet groups showed an increase in saturated fatty acids and polyunsaturated fatty acids, but a decrease in mono unsaturated fatty acids when compared to the basal diet groups. The composition ratio of fatty acids varied according to which type of oil the diet contains. Our finding suggest that grape seed oil was an apparent diet effect on the fatty-acid composition.
This study aims to identify the dietary patterns relevant to obesity of Korean women among low income classes. Adults 20-64 years were used as study subjects from the data of 2005 Korea National Health and Nutrition Examination Survey. We compared obese and normal-weight women in terms of their nutrients intake, diet quality and food patterns. Diet quality was assessed by using the Nutritional Adequacy Ratio (NAR) and Index of Nutritional Quality (INQ). Our results showed higher prevalence of obesity among lower socioeconomic status women. In men, there were no significant associations with socioeconomic status and prevalence of obesity. Higher risk of nutritional inadequacy was observed among obese women compared to normal weight women. Obese women showed significantly lower INQ for nutrients such as Ca, Fe, Vitamin A, Thiamin, Riboflavin and Vitamin C compared to other women. They consumed significantly higher amount of rice (p < 0.05) and lower amount of vegetables (p < 0.01). By contrast, obese men from low income classes showed higher intake of those nutrients. Obese men also consumed significantly higher amount of meats than normal weight men. Therefore, this study suggests that gender-specific approaches based on economic situation should be considered in developing the intervention program for managing obesity for low income classes.
The purpose of this study was to identify population subgroups with similar patterns of diet quality, physical activity, alcohol consumption and cigarette smoking of Korean. The cluster analysis was conducted using the data from Korea National Health Survey(KNHS) in 1995, which consisted of 5,805 persons. We identified six health behavior typologies : 32.9% of the sample had a good diet but sedentary activity level(good diet lifestyle), 7.2% had high activity level but less diet quality(fitness lifestyle). Individuals in the passive lifestyle cluster(39.1%) had no active health promoting activities but tended to avoid risk taking health behavior such as cigarette smoking and alcohol drinking. 1.1% of the sample were in a drinking cluster, 17.2% in a smoking cluster and 2.5% had a hedonic lifestyle characterized by heavy drinking and smoking. The other characteristics of these lifestyle clusters could be presented by demographic and socioeconomic factors.
This study was undertaken to classify Enterobacter sakazakii isolates from 13 powdered infant formula products, 25 powdered weaning diet products, and 33 weaning diet ingredients on polymerse chain reaction (PCR) methods. The numbers of the isolates from 1 powdered infant formula product, 7 powdered weaning diet products, and 6 weaning diet ingredients were 1, 14, and 8, respectively. The contaminated ingredients were 1 rice powder, 2 millet powders, 2 vegetable powders, and 1 fruit and vegetable premix. PCR with the primer of repetitive extragenic palindromic element (REP-PCR) and random amplification of polymorphic DNA(RAPD) were effective in discriminating among the isolates, but tRNA-PCR and PCR with the primer of l6S-23S internal transcribed spacer (ITS-PCR) were not. Some of E. sakazakii isolates from vegetable powders, fruit and vegetable premix, and millets powders were classified into the clonal groups based on the DNA patterns in the REP-PCR and RAPD analysis. A close genetic relationship among the isolates from some of the powdered weaning diet products and the rice powder was also detected in the cluster analysis based on the DNA patterns in RAPD.
This study was carried on the analysis of nutritional value and preference between the plain gruel (Hyun Jook) and the experimental gruel (Tarak Jook, Jangkook Jook & Chajohonhab Jook) in order to improve the quality and variety of menu patterns of gruels for the patients requiring soft diet. The results obtained are as follows: 1. In comparing the calorie coutent of each gruel, Tarak Jook, Jangkook Jook, and Chajohonhab Jook had more calories-82.7%), 39.3% and 12.4% respectively-than Hyun Jook. Additionally, in the case of protein content, Tarak Jook, Jangkook Jook and Chajohonhab Jook showed higher values than Hyun Jook by 270%, 137% and 28.3% respectively. 2. The preference for each experimental gruel compared with Hyun Jook, as a function of taste, color and concentration of the gruels was shown to be insignificant. But the color and concentration did effect the preference level for each gruel. Hoverer, patients did have a preference for particular gruels: Jankook Jook, Tarak Jook, Chajohorhab Jook in descending order. 3. Overall, 65.6% of the patients requiring soft diet thought gruel was only for the sick 57.1%) thought the reason for gruel as a soft diet was that it could be digested easily 75.8% of the patients disliked gruel and their frequency of intake was very low 78.8% did not know more than 5 types of gruel. Hoverer patients did prefer a loose gluel(48.4%). In couclusion, awareness of gruel as a soft diet for patients and its intake as one not to meution as a normal diet was low.
This study was conducted to examine the nutritional status, quality of diet and quality of life in postmenopausal women with mild climacteric symptoms based on their food group intake patterns. The data for nutritional status were obtained using 3-day records. Quality of diet was assessed by INQ, NAR, MAR, DDS, DVS, DQI-I. Climacteric symptoms were analyzed by the questionnaire of Kupperman's index and MENoL. The subjects were classified into the five groups, GMVDF, GMVdF, GMVDf, GMVdf, GmVDF according to their food group intake patterns. Analysis of nutrient intakes showed that the GMVDF group took significantly higher levels of kcal, carbohydrate, protein, fat, vitamin A, thiamin, riboflavin, folate, vitamin C, vitamin E, calcium, phosphorous, sodium, iron, zinc and fiber than GMVdf group did (p < 0.05). INQ of Ca and Fe appeared to be higher in GMVDF than in GMVdf groups (p < 0.05). Analysis of NARs showed that missing milk groups took lower riboflavin, Ca and P than other groups did as the same result with MAR (p < 0.05). Analysis of DDS and DQI showed that GMVdf group had the lowest quality of diet (p < 0.05); however, no difference was found on DVS. The GMVdf group showed the worst climacteric symptoms compared with those of the other groups (p < 0.05). However, we couldn't observe any differences in menopause-specific quality of life among the groups. In conclusion, it would be beneficial to meet all five food groups to increase the quality of diet and to reduce the climacteric symptoms in postmenopausal women.
Data are limited on the association between dietary patterns and screen time among Korean adolescents. The present study identified dietary patterns of 691 adolescents, aged 13-18 years, who had participated in the Third Korean National Health and Nutrition Examination Survey (KNHANES III) and analyzed their associations with screen time. Screen time was defined as the time spent watching TV, using a computer, or playing video games was calculated as a sum of all these times. Dietary patterns and their factor scores were derived from a food frequency questionnaire using the factor analysis method. To analyze the association between dietary patterns and screen time, we conducted multiple linear regression analysis. We also performed multiple logistic regression analysis to estimate odds ratios (OR) of excessive screen time (2 hours or longer per day) and 95% confidence intervals (CI). We identified 2 dietary patterns labeled "the Korean healthy dietary pattern" and "the Western diet and fast foods pattern". The former included mixed grains, legumes, potatoes, red meat, eggs, fish, dairy products, fruits, vegetables, seaweeds, and mushrooms, whereas the latter included noodles, bread, red meat, poultry, fast foods, snack, and soft drinks. After controlling for potential confounding factors, factor scores for the Korean healthy dietary pattern were inversely associated (P-value for trend < 0.01) and those for the Western diet and fast foods pattern were positively associated with the screen time (P-value for trend < 0.01). Adolescents in the top tertile of the scores for the Korean healthy dietary pattern had a multivariable-adjusted OR [95% CI] of 0.44 (0.25-0.75) for excessive screen time compared with those in the lowest tertile. On the basis of these findings, adolescents who have excessive screen time may need to be encouraged to consume a more healthy diet.
In this study, 230 female college students in Seoul area were surveyed to evaluate their eating habits and behavior, physical activities, and patterns of purchasing diet/low-calorie food. Their body composition was also determined using bioelectrical impedance(Inbody 520). The subjects were divided into two groups according to their BMI index with a mean BMI of 20.2$\pm$1.5(normal) weight and 25.0$\pm$1.7(obesity). Overall, 85.7% of the subjects reported that the food they purchase depends more on their preferences than the nutritional value of the food. When the two groups were compared there was no significant difference in the frequency or experience of purchasing diet-foods. Indeed, 69.3% of all female college students had purchased diet foods, and most consumed these foods 2~3 times a week. Obese group preferred a savory taste, while normal group preferred a sweet taste. The majority of the subjects(80.8%) answered that they "read nutritional labels carefully upon purchasing diet food", and that they examined calories(61.8%) and total fat(48.5%) most carefully. Of the types of low-calorie/diet foods purchased, beverages were the most commonly obtained; followed by noodles, diet-bars, and snacks. The most commonly purchased low calorie snacks were "potato-type C(hot-flavor)" and "potato-type A(salty-flavor)", while the most commonly purchased diet-bars were "low calorie-type A"(55.3%) and "high protein-bar"(32.3%). The most commonly purchased noodles were "thick noodle type"(65.1%), while the most commonly purchased drinks were "cereal tea"(65.1%) and "mixed herb tea"(66.0%). Overall, factors such as self-esteem or the degree of body satisfaction, rather than obesity(BMI index) itself, were significantly correlated with the frequency of purchasing diet-foods.
