In this study, factors involved in lipid and energy metabolism following treatment with ethanolic extract of the Polygonatum sibiricum rhizome (ID1216) were evaluated in high-fat diet-induced obese mice. ID1216-treated mice showed a significant reduction in weight gain compared to non-treated mice. ID1216 treatment increased the protein levels of AMP-dependent protein kinase, sirtuin1, peroxisome proliferator-activated receptor ${\gamma}$ coactivator 1-${\alpha}$ ($PGC1{\alpha}$), peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) and uncoupling proteins in the adipose tissue, liver and muscle compared to vehicle treatment. Analysis of downstream signals of the sirtuin1 $PGC1{\alpha}$-$PPAR{\alpha}$ pathway showed that ID1216 regulates the expression of ${\beta}$-oxidation related genes such as acyl-CoA oxidase, carnitine palmitoyltransferase1, acyl-CoA dehydrogenase and adipocyte protein 2. In addition, ID1216 increased the expression of adipose triglyceride lipase. These results suggest that ID1216 has anti-obesity effects by regulating the genes involved thermogenesis, ${\beta}$-oxidation and lipolysis in a diet-induced obesity model.

This study was conducted among the university students to evaluate the recognition of food calories through questionnaire. The subjects were 88 male and 230 female students in Chungnam. 67.4% of the subjects experienced nutrition education, 50.8% and 86.6% of them recognized daily calorie requirement and definition of calorie, respectively. There were significant differences in response rate about frequency of supper, experience and satisfaction of weight control, degree of knowledge of calorie, and need of nutrition education among the subjects with experience of nutrition education and recognition of daily calorie requirement and calorie definition. The calories of 14 food items (29.17%) were low recognized in subjects with nutrition education than in subjects without nutrition education. The results also show that the calories of 38 food items (79.17%) were highly recognized than the actual clories of them in total subjects. Especially, vegetables, fruits, and oils were highly recognized. The daily calorie intakes in the subjects recognizing calorie definition were lower than in the other subjects(p<0.05). In conclusion, university students highly recognized than actual food calories, and there was significant difference in degree of recognition with various factors, such as nutrition education, knowledge of calorie, and weight control, and therefore showing a strong need of proper nutrition education about food calories.

The study was performed for investigation with 257 female adults to find out the factors affecting health control behavior and obesity stress by personality type. First of all, BMIs of the respondents showed 30 low weight (11.7%), 170 normal weight (66.1%), 33 overweight (12.8%) and 24 obese respondents (9.4%). Comparing with low weight or normal weight, overweight or obesity could be seen as strong with diet control behaviors, from which obesity stress showed the tendency to be high accordingly. Second, the result of the investigation showed that for the open personality, which was featured as strongly desired to accomplish, very sincere and sensitive, they were more eager to control through health or diet. Third, the result of the investigation showed that for the more nervous, which is featured as emotionally unstable, bad at self control of impetus and clumsy to handle stress, the obesity stress was escalating.

The purpose of this study was to compare energy intake according to expected body mass index (BMI) in adolescents. A total of 280 middle school students were divided into current or/and expected obesity groups (underweight group; UWG, normal weight group; NWG, and overweight group; OWG) by BMI to compare energy intake and perception on body shape and weight control. The average age of total subjects was 15 years, and the distributions of boys and girls were 52.5% and 47.5%, respectively. The distribution of boys and girls was not significantly different among current obesity groups but was among expected obesity groups (15% and 82% in UWG vs. 71.4% and 16.5% NWG vs. 13.6% and 1.5% in OWG; P<0.001), indicating that girls wanted to lose weight more than boys. For body shape, most subjects in current obesity groups responded "fitness" in UWG (38.7%), "fitness" and "slightly chubby" in NWG (45.5% and 39%), and "slightly chubby" in OWG (65.2%), showing a significant difference (P<0.001). For interest in weight control, most subjects responded "average" in current UWcinterested" in current OWG (52.2%), whereas they responded "very interested" in expected UWG (55.7%), "average" in expected NWG (51.2%), and "not interested" in expected OWG (45.5%), showing a significant difference (P<0.001). The percentage of subjects with experience with weight control was significantly high in current OWG (71.7%), NWG (51.2%) and UWG (34.2%) as well as in expected UWG (57.3%), NWG (40.2%) and OWG (36.4%) in descending order (P<0.001). The daily energy intake of total subjects was 2,057.1 kcal without any significant difference among current obesity groups. However, it was significantly lower in expected UWG than expected NWG and OWG (1,943.1 kcal vs. 2,165.0 kcal or/and 2,152.1 kcal; P<0.001). To sum up these results, girls wanted to lose weight more than boys. The more students wanted to lose weight, the greater their experience and interest in weight control and the lower their energy intake.

This study examined the anti-obesity effect of krill oil (KO) by regulating adipokines in a high-fat diet (HFD)-induced obese mouse model. The mice were fed a 60 kcal% HFD for 16 weeks, and KO was then administered at an oral dose of 100, 200, and 500 mg/kg/day for four weeks before the end of the experiment. The administration of KO at concentrations of 200 and 500 mg/kg/day decreased body weight gain significantly compared with the HFD-fed control group. In addition, the HFD-fed control group showed the abnormal release of adipokines by an increase in leptin and decrease in adiponectin, compared to the normal diet-fed normal group. On the other hand, KO (500 mg/kg/day)-administered group attenuated the abnormal release of adipokines by the down-regulation of leptin and the up-regulation of adiponectin. Therefore, KO could be a promising therapeutic agent for obesity by the regulation of adipokines.

Purpose: The purpose of this study was to investigate the relationship between obesity, body image perception, and weight control for obesity management in adult women. Methods: The subjects of this study were 3,617 women aged over 19 years, who participated in the Seventh Korea National Health and Nutrition Examination Survey 2016. Data were analyzed through complex sampling design data analysis. Results: Right body image perception according to obesity was apparent between 70.6-81.7% of women and 76.5% of women with abdominal obesity perceived that they were normal. Obese women performed more weight control than non-obese women. Women with only abdominal obesity performed less weight control than non-obese women, and 47.3% of them performed weight control. Women who perceived themselves as obese performed more weight control than women who perceived themselves as non-obese (odds ratio, 2.08; confidence interval, 1.69-2.57), but body mass index was not observed to be associated with weight control. Conclusions: Education on abdominal obesity should be provided to increase awareness about abdominal obesity and its effective management, especially in women with only abdominal obesity. In addition, interventions for right body type perception should be provided for proper weight control along with prevention and management of obesity.

소아 당뇨병은 일반적으로 인슐린의존성과 비의존성으로 구분된다. 인슐린의존성은 체내에서 혈당을 조절하는 인슐린이 분비되지 않아 인슐린주사에 의존해야 하는 경우, 비의존성은 비만 등으로 인슐린 작용이 감소하는 것으로 체중을 줄이거나 식이요법 등으로 조절이 가능하다. 19세미만 소아당뇨병의 90%는 인슐린의존성으로 바이러스 감염 후 자가항체가 생기거나 아황산가스 질소 등 공해물질에 의해 췌장이 파괴해 발생한다. 주로 10$\~$13세 또는 6$\~$8세에 많이 생기며, 한 번 발병하면 췌장이 재생되지 않아 평생 인슐린주사를 맞아야 한다. 우리나라는 인구 10만명당 1.2명으로 서구보다 발병률이 낮은 편이나 5년전에 비해 2배 가량 급증하고 있다.
