The Korean diet, including breakfast, is becoming more Western, which could increase the risk of metabolic syndrome. Our aim was to assess whether breakfast patterns are associated with risk for metabolic syndrome in Korean adults. The study subjects (n=371; 103 men, 268 women) were employees of Jaesang Hospital in Korea and their acquaintances, and all subjects were between 30 and 50 years old. The data collected from each subject included anthropometric measurements, three-day food intake, blood pressure (BP) and blood analyses. The three breakfast patterns identified by factor analysis were "Rice, Kimchi and Vegetables", "Potatoes, Fruits and Nuts" and "Eggs, Breads and Processed meat". The "Rice, Kimchi and Vegetables" pattern scores were positively correlated with systolic (SBP) and diastolic blood pressure (DBP) measurements in men (P<0.05) and with serum triglyceride (TG) levels in women (P<0.05). The "Eggs, Breads and Processed meat" pattern scores correlated positively with weight, body mass index (P<0.05) and serum TGs (P<0.01) in men. The "Potatoes, Fruits and Nuts" pattern was associated with lower risk of elevated BP (OR 0.49, 95% CI 0.28-0.88) and fasting glucose levels (OR 0.51, 95% CI 0.26-1.00). In contrast, the "Eggs, Breads and Processed meat" pattern was associated with increased risk of elevated TGs (OR 2.06, 95% CI 1.06-3.98). Our results indicate that reducing the consumption of eggs, western grains and processed meat while increasing fruit, nut and vegetable intake for breakfast could have beneficial effects on decreasing metabolic syndrome risk in Korean adults.

BACKGROUND/OBJECTIVES: Different fatty acids exert different health benefits. This study investigated the potential protective effects of perilla, olive, and safflower oils on high-fat diet-induced obesity and colon inflammation. MATERIALS/METHODS: Five-week old, C57BL/6J mice were assigned to 5 groups: low-fat diet (LFD), high-fat diet (HFD) and high-fat diet supplemented with-perilla oil (HPO), olive oil (HOO), and safflower oil (HSO). After 16 weeks of the experimental period, the mice were sacrificed, and blood and tissues were collected. The serum was analyzed for obesity- and inflammation-related biomarkers. Gene expression of the biomarkers in the liver, adipose tissue, and colon tissue was analyzed. Micro-computed tomography (CT) analysis was performed one week before sacrifice. RESULTS: Treatment with all the three oils significantly improved obesity-induced increases in body weight, liver weight, and epididymal fat weight as well as serum triglyceride and leptin levels. Treatment with perilla oil (PO) and safflower oil (SO) increased adiponectin levels. The micro-CT analysis revealed that PO and SO reduced abdominal fat volume considerably. The mRNA expression of lipogenic genes was reduced in all the three oilsupplemented groups and PO upregulated lipid oxidation in the liver. Supplementation of oils improved macroscopic score, increased colon length, and decreased serum endotoxin and proinflammatory cytokine levels in the colon. The abundance of Bifidobacteria was increased and that of Enterobacteriaceae was reduced in the PO-supplemented group. All three oils reduced proinflammatory cytokine levels, as indicated by the mRNA expression. In addition, PO increased the expression of tight junction proteins. CONCLUSIONS: Taken together, our data indicate that the three oils exert similar anti-obesity effects. Interestingly, compared with olive oil and SO, PO provides better protection against high-fat diet-induced colon inflammation, suggesting that PO consumption helps manage inflammation-related diseases and provides omega-3 fatty acids needed by the body.

The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a "Check" group(n=62, 47.3%) and a "No check" group(n=69, 52.7%). Reasons given for not reading nutrition labelings were "a habit of buying" for 72.2%, and "too small or rude" for 19.1%. The "Check" group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the "No check" group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered "expiry date"(n=87, 66.4%) to be more important information on food labels than "nutrient composition"(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

Background: Bladder cancer is one the most common malignancies of the genitourinary tract. The present study aimed to assess the epidemiology, of bladder cancer in Mazandaran, a large province in northern Iran as high-incidence cancer area, during a 2-year period. Methods: The data for this study were obtained from the population-based cancer registry of the Vice-Chancellory for Health Affairs of Mazandaran University of Medical Sciences and Mazandaran hospitals between March 1, 2010 and March 1, 2011. Demographic data, including sex, age, residency and symptoms were investigated through careful review of medical records. Using a questionnaire protocol, several variables were assessed for these cases such as smoking, history of opium, vegetable consumption habits, and history of other cancers. Results: A total of 112 cases were analyzed, 98 (87.5%) in men and 14 (12.5%) in women (mean age of $68.0{\pm}14.6$ years). Urban and rural residence were 60.7% and 39.3%. Tobacco and opium use were found in 45.5% and 21.4% of patients, respectively. Approximately 60% consumed vegetables an average of fewer than one time per day. Hematuria was the first symptom in these cases which were mainly diagnosed as having bladder cancer by ultrasonography. Conclusion: The results showed that bladder cancer tends to be found in the elderly and the male to female ratio is high. Macroscopic hematuria is a very important symptom for indicating probably urothelial tumor that should be followed up patients with transabdominal ultrasonography as a routine modality.

To assess the food intake and diet quality of Koreans living in rural areas with discriminative environment, this dietary survey was conducted with 553 subjects living in five different rural areas using a one-day, 24-hour recall method. The average weight of total food intake was 1066g, with vegetable and animal food comprising 83.75 and 16.3% of total food intake, respectively. The average daily food intakes of residents in the five areas were 985g, 1005g, 1028g, 1318g, and 964g, and were significantly different(p<0.001). Residents of Ulju consumed the largest amount of food, 1318g. The total number of food items consumed was 336. The foods consumed in largest amounts were rice(223g), Korean cabbage-Kimch'i(111g), and soybean curd(41g). The foods consumed most frequently were rice, Korean cabbage-Kimchi, green onion and garlic. When investigating the consumption pattern of the major five food groups, only 5% of subjects consumed all five groups. The groups most frequently missing were dairy products and fruits. The average number of foods consumed per day was 16.8, but differed significantly by area(p<0.001). The number of major food groups (DDS, dietary diversity score) and that of food items(DVS, dietary variety score) correlated positively with NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio). People with a DDS of above 4 or DVS of above 20 met two-thirds of the recommended dietary allowance for most nutrients. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. dietary guidelines should be made considering the nutritional characteristics of different areas to improve the health of people living in those areas.

The purpose of this study was to identify dietary factors related to the incidence of diabetes mellitus in Korea. The study consisted of 165 diabetic patients, male and female, aged 30 to 70 years and 198 healthy persons as controls. Diabetic patients who had been diagnosed with diabetes mellitus for less than five years before the study period were recruited from eight different hospitals located in Seoul, Korea. Socioeconomic status, state of illness, physical activity, food habits and food intake were assessed. Food intake was assessed by food frequency questionnaire method using a 105-food frequency questionnaire developed for diabetic patients. The stress and activity indices of diabetic patients were not significantly different from control, but alcohol consumption and smoking levels were higher in diabetics than controls. Other diseases of male diabetic patients included liver diseases, digestive system diseases, and hypertension, while those of female diabetics were hypertension, neuralgia, arthritis and digestive system diseases. These disease patterns are different from Western countries whose most common complications are hypertension and hyperlipidemia. More irregular and less varied meals were found in the diabetic group compared to the control group, suggesting that diabetic patients have generally undesirable food habits. Otherwise, food and nutrient intake of diabetics did not differ greatly from the control group. It was found that diabetic patients consumed more cereals and less fruit than the control group, and also that male diabetics consumed more alcohol. The carbohydrate : protein : fat energy distribution ratio was 61.7 : 15.8 : 22.5 in male patients and 65.1 : 14.9 : 19.7 in female patients. Discriminant analysis showed that diabetes risk factors differed with sex. In male patients, the important factors were body mass index(BMI), vitamin C intake, family diabetic history and vegetable intake, while in female patients they were BMI, cereals intake, carbohydrate intake, vitamin C intake, stress, food habits and Ca intake. These results show that excessive intake of energy and fat are not the major causal factors in Korean NIDDM. Therefore, the diabetes risk factors of Western countries may not directly apply to Koreans. Mors study is needed to clarify the risk factors of Korean NIDDM.

This study was conducted to identify the characteristics of Korean diet in the view of food and food group intakes. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Rice was a major contributor to many nutrients intake because of the amount of consumption. Vegetable oil made great contribution to fat intakes and eggs, squid, and anchovy supplied much cholesterol compared to other foods in all the age groups. Milk was major contributor of fat and cholesterol as well as calcium in younger age group, and seasoning gave much contribution to iron intakes. Mean dietary variety score(DVS) was 32 for EC group and 17 for subjects over 70 years, and tended to decrease along the increasing age. EC group consumed most variable number of foods of all groups but they consumed many junk foods, therefore the MAR value was low despite their high DVS value. Mean dietary diversity score(DDS) of each age group from PC group to subjects over 70 years was 4.34, 4.28, 3.79, 3.89, 3.76, 3.56, and 3.25, respectively. Food group, which was consumed below the minimum amount, was mainly fruits in all the age groups, and many subjects in HS group and over 30 years consumed dairy products below the minimum amount. From these results, age specific nutritional problems were found. PC group and subjects over 50 years seemed to need more diverse food intake than now, EC group did nutrient dense food, and HS group and subjects over 30 years did dairy products. Also, subjects took various nutrients from rice and seasoning contributed to some nutrients intakes. (Korean J Nutrition 34(5) : 568∼579, 2001)

This study compared obese children's food group intakes with the new Dietary References Intakes for Koreans (KDRIs) food guides for 5th-6th grade school children. This study also determined the extent of sedentary life styles related with obesity in this area of children. This is it cross-sectional study of 799 school children. The dietitian sent a survey form describing the project and a questionnaire to the subject's family. The questionnaire included child demographics, family history of chronic diseases, the daily servings of five food groups, such as grains, meat and beans, dairy products, fruits, and vegetables. The daily or weekly hours of physical activity, television viewing, and computer usage were also surveyed. Obesity index (%) of the subjects was calculated, and children with an obesity index (%) equal to or greater than 20 were classified as the obese. Among the 799 participants, 50.7% were female. The percentages of the normal and the obese were 691 (86.5%) and 108 (13.5%) respectively. Obese children reported eating less vegetables (p<0.05), more high sugar snacks (p<0.05), and high fat snacks (p<0.05) than normal children. No significant differences in food servings of grains, meats and beans, and fruits, and dairy products between the normal and the obese were shown. Obese children reported fewer hours of physical activities (p<0.05) and more hours of computer usage (p<0.05) than normal children. Girls showed less likelihood of being obese (odds ratio, 0.575, CI (0.38, 0.87), p<0.05). More hours of physical activity significantly decreased the likelihood of being obese (odds ratio, 0.572, CI (0.35, 0.92), p<0.05). Family history of obesity almost doubled the likelihood of obesity in children (odds ratio, 2.653, CI (1.660, 4.241), p<0.05). In conclusion, frequent snacking, inadequate vegetable consumption, and sedentary lifestyle increased significantly the likelihood of obesity in children, which suggest that obesity intervention in this age group should focuse more on those variables.

Quinoa (Chenopodium quinoa Willd.) is a grain crop with high nutritional value. The leaves and sprouts of quinoa can also be consumed either raw or cooked, providing considerably nutritional value as well as high antioxidant and anticancer activities. This study was carried out to obtain basic data to assist in the practical design of a plant factory with artificial lighting for the cultivation of quinoa as a leafy vegetable. We estimated the energy content of the quinoa and the electrical energy required to produce this crop. The yield was 1,000 plants per day, with a planting density and light intensity of $0.015m^2$ ($15{\times}10cm$) and $200{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, respectively. The total number of plants, cultivation area, and electricity consumption were estimated to be 25,000, $375m^2$, and $93,750{\mu}mol{\cdot}s^{-1}$, respectively. White fluorescent lamps were used at a power of 20.4 kW from 1,857 fluorescent lamps (FL, 55 W), and the cost for electricity was approximately 1,820 dollars (exchange rate of $1 = 1,200 won) per month. For a daily harvest of 1,000 plants per day in a closed plant factory, the estimated light installation cost, total installation cost, and total production cost would be 15,473, 46,421, and 55,704 dollars, respectively. The calculated production cost per plant, including labor costs, would be 27 cents for the 25-day cultivation period, with a marketable ratio of 80%. Considering the annual total expenses, income, and depreciation costs, the selling price per plant was estimated to be approximately 56 cents.

Purpose: The purpose of this study was to review health-related interventions in nursing studies for low-income school-age children and adolescents. Methods: Searches among CINAHL, MEDLINE, PubMed, EMBASE, DBpia, and RISS identified 27 intervention studies published from January 2000 to April 2018. Results: Twenty-seven intervention studies were identified: 12 included psychosocial adaptations and 15 included the healthy lifestyle promotion and disease prevention. The settings were mainly schools and community welfare centers. Many studies were based on social cognitive theory and interventions were provided in a group format. Depression, self-esteem, resilience, self-efficacy for vegetable and fruit consumption, physical activity, and health-related knowledge improved significantly after the health-related interventions. However, the findings were inconsistent with regard to anxiety, peer relationships, body mass index (BMI), blood pressure, cholesterol, and glucose. Conclusion: There is potential for enhancing outcomes for psychosocial, physical health, and health-related knowledge among low-income school-age children and adolescents. Integrated interventions addressing the physical as well as psychological health of low-income children and adolescents should be conducted. It would be prudent to consider the ethnicity and family background of the child or adolescent. However, rigorous study designs and scientific validation are needed for further evidence.
