BACKGROUND/OBJECTIVES: Eating-out among Korean people has become an important part of modern lifestyle due to tremendous growth of the food service industry and various social and economic changes. This study examined trends in meal patterns and meal sources while eating-out among Korean adults aged 19 years and older. SUBJECTS/METHODS: Data were from the 1998-2012 KNHNES (Korea National Health and Nutrition Examination Survey) by the 24-hour dietary recall method. This study included 55,718 adults aged 19 years and older. For analysis of eating-out frequency, data were categorized by source of meals and serving place. RESULTS: Average frequency of meals consumed away from home increased from 1998 to 2012, although it remained lower than that of meals at home. In addition, male, unmarried, employed, higher educated, and high income individuals more frequently consumed meals away from home. Moreover, sodium intake while eating-out significantly increased from 2,370 mg in 1998 to 2,935 mg in 2012. Lastly, percentage contributions of daily total protein intake, fat intake, and sodium intake from eating-out increased to more than half (53-55%) in 2012 compared with 47-48% in 1998. CONCLUSIONS: As eating-out has grown in popularity, greater recognition of public health and nutritional education aimed at promoting healthy food choices is needed. In addition to developing consumer education for overall healthier eating patterns, individuals who are younger, unmarried, higher educated, and males are especially at risk and require attention.

The purpose of this study was to obtain normative nasalance scores for adult subjects speaking the Korean language. Additional objectives of the study were to determine if speaker sex played a role in differences in nasalance score and there was significantly correlation of nasalance score with nasalance slope score. The subjects include 75 healthy young Korean adults with normal oral and velopharyngeal resource and function. They had no history of speech problem, were judged as having normal speech and resonance at the time of testing, and had no upper respiratory tract infections or allergies at the time of testing. The Nasometer II 6400 was used to obtain nasalance scores and nasalance slope scores for /a/, /i/, /e/, /o/, /u/, /ja/, /je/, /wi/, /p'ap'i/ and /sasi/. The data of nasalance and nasalance slope were analyzed statistically. The mean nasalance score of the female was significantly higher than that of male at /a/, /i/, /wi/, /p'ap'i/ and /sasi/(p <0.10). The mean nasalance score of /i/ was highest and that of /o/ was the lowest. In this study, we could not and the relationship of the nasalance score and the closing slope score. However, there was negative correlation between the mean nasalance score and the opening slope score at ie/ and /;ai, positive to /sasi/. These normative nasalance scores for normal young adults speaking the Korean language provide important reference information for Korean cleft palate teams. In the future study of velopharygneal activity with the Nasometer, the opening slope score will be able to be the important parameter.

Objective : The aims of this study was to evaluate relationship between body dissatisfaction, personality characteristic, and stress in young adults. Methods : One hundred and ninety five young, healthy, and normal participants filled out all 3 types of self-reported questionnaire, the Body Dysmorphic Disorder Examination-Self Report (Korean version of BDDE-SR ; K-BDDE-SR), Neuroticism, Extraversion, Openness-Five Factor Inventory (NEO-FFI) and Stress Scale of Korean version of the Depression Anxiety Stress Scale (K-DASS-21). Results : Out of the 195 participants, 30% (n=59) was male and 70% (n=136) was female. There was no statistical difference between high K-BDDE-SR group (K-BDDE-SR score 75 percentile or higher, n=50) and low K-BDDE-SR group (K-BDDE-SR score below than 75 percentile, n=145) in terms of weight, height, and BMI. In high K-BDDE-SR group, neuroticism was significantly higher than low K-BDDE-SR group, and extraversion, agreeableness, conscientiousness were significantly lower than low K-BDDE-SR group. Also, level of stress in high K-BDDE-SR group was significantly higher than low K-BDDE-SR group. Conclusion : Our study revealed that individual's with more body dissatisfaction were more neurotic and stressful. Thus, body dissatisfaction and diverse psychiatric diseases should be considered in treating neurotic and stressful young adults.

[Purpose] Aerobic exercise training (AT) reverses aging-induced deterioration of arterial stiffness via increased arterial nitric oxide (NO) production. Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of NO synthase, was decreased by AT. However, whether AT-induced changes in ADMA levels are related to changes in nitrite/nitrate (NOx) levels remains unclear. Accordingly, we aimed to clarify whether the relationship between plasma ADMA and NOx levels afected the AT-induced reduction of arterial stifness in middle-aged and older adults. [Methods] Thirty-one healthy middle-aged and older male and female subjects (66.4 ± 1.3 years) were randomly divided into two groups: exercise intervention and sedentary controls. Subjects in the training group completed an 8-week AT (60%-70% peak oxygen uptake [${\dot{V}}O_{2peak}$] for 45 min, 3 days/week). [Results] AT signifcantly increased ${\dot{V}}O_{2peak}$ (P < 0.05) and decreased carotid β-stifness (P < 0.01). Moreover, plasma ADMA levels were significantly decreased while plasma NOx levels and NOx/ADMA ratio were significantly increased by AT (P < 0.01). Additionally, no sex diferences in AT-induced changes of circulating ADMA and NOx levels, NOx/ADMA ratio, and carotid β-stifness were observed. Furthermore, the AT-induced increase in circulating ADMA levels was negatively correlated with an increase in circulating NOx levels (r = -0.414, P < 0.05), and the AT-induced increase in NOx/ADMA ratio was negatively correlated with a decrease in carotid β-stifness (r = -0.514, P < 0.01). [Conclusion] These results suggest that the increase in circulating NOx with reduction of ADMA elicited by AT is associated with a decrease in arterial stiffness regardless of sex in middle-aged and older adults.

BACKGROUND/OBJECTIVES: The obese population is rapidly increasing because of reduced physical activity and a Westernized diet; consequently, various chronic diseases are more prevalent. With the increasing interest in body shape and appearance, research on body shape perceptions and accompanying weight control behaviors are needed for healthy weight management. SUBJECTS/METHODS: A cross-sectional survey was conducted on randomly selected 536 (209 men and 327 women) aged 20 to 65 years. Body mass index (BMI), body-shape perception, weight control behavior, quality of sleep, and place of residence were collected using self-reported questionnaires. Multivariable logistic regression analysis was conducted using complex design in each groups. Collected data were analyzed using the SAS 9.4 statistical package, and the significance level was set at P < 0.05. RESULTS: When these two variables were divided into four groups, they were found to influence dieting attempts. People with abnormal weights who were dissatisfied with their body shapes attempted dieting 5.23 times more than those with healthy weights and satisfaction with their body shapes. Further, those with normal weights but dissatisfaction with their bodies attempted dieting 4.45 times more than those who were satisfied with their shapes. Subjects in their 20s attempted dieting 2.53 times more than those in their 30s and 40s, and female subjects attempted dieting 2.24 times more than male subjects. CONCLUSIONS: A correct perception of one's shape can be an important factor for dietary behavior, as body shape perceptions and dieting attempts are strongly related. Additionally, healthy weight management and nutrition education are important elements to incorporate into a weight control program aimed at preventing excessive weight control behaviors and promoting correct perceptions of body shape.

A variety of studies show that a centraized rather than a generalized pattern of subcutaneous fat distribution is more directly associated with disorers of carbohydrate and lipid metabolism, as possibly hypertension, This study was an attempt to observe the relationship of body fat distribution, blood lipids, blood pressure and exercise in 85 healthy men and women. Within this group there was a gradation of fat distribution progressing from LBSO and UBSO defined on the basis of WHR. This paper reports the relationship of body fat distribution defined by WHR to plasma glucose, lipids, blood pressure, and exercise in this population. Although the obesity indices(RBW and BMI) were slightly higher in the UBSO group, significant differences existed between UBSO and LBSO groups with respect to WHR blood pressure, and total cholesterol concentration in female. WHR values were substantially different and this was primarily due to greater degrees of differences in waist as opposed to hips circum ference. Although no significant differences existed between UBSO and LBSO groups with respect to age, body weight, and hips circumference, energy intake, total cholesterol, LDL-cholesterol and WHR values were substantially different in male. Positive, significant correlations were found between WHR and both systolic and diastolic blood pressure and between WHR and the total plasma cholesterol concentration and age. When 26 pairs of exercise and nonexercise groups were matched according to sex, age and body weight, blood pressure and blood lipids were significantly lower in the exercise groups than those in the nonexercise groups. In conclusion, these findings suggest that an altered blood lipid profiles will manifast in men and women with upper body obese. Furthermore these findings suggest that exercise and physical activity may be beneficial for controlling blood lipids and blood pressure in healthy adults.

연구배경: 우리나라의 노력성 호기곡선을 이용한 폐활량측정법 검사지표들의 추정정상치에 관한 연구는 청년과 중년층이 대부분인 집단을 대상으로 이루어져 실제 폐기능검사를 많이 하는 고령인구를 거의 포함하고 있지 않다. 이에 저자들은 일부 농촌지역 50세 이상 건강인군에서 폐활량측정법 검사지표들의 추정정상치 산출 공식을 구하고 이들 기존의 연구들과 비교하여 고연령층에서 적정한 폐활량측정법 검사지표들의 추정정상치를 살펴보고자 했다. 방 법: 일부 농촌지역 50세 이상 성인 533명(남자 215명, 여자 318명)을 대상으로 적절한 폐기능검사를 행했으며 담배를 피지 않으며 만성기침, 가래, 천명 등의 호흡이 증상과 심폐질환의 과거력, 척추와 흉곽의 변형 등 호흡기계에 영향을 끼치는 항목을 갖지 않는 건강인군 남자 32명, 여자 110명을 선정하였다. 이들로부터 노력성 호기곡선을 이용한 폐활량측정법 검사지표들의 추정정상치를 위한 회귀방정식을 구하고 다른 연구의 회귀방정식과 비교해 보았다. 결 과: 남녀 모두에서 FVC는 나이와 음의 상관관계를, 키와는 양의 상관관계를 나타냈다. $FEV_1$은 여자에서는 나이와 음의 상관관계를, 키와는 양의 상관관계를 나타냈으나 남자에서는 키 대신 몸무게가 양의 상관관계를 나타냈다. 남녀 모두에서 FEVl%와 유의한 상관을 보이는 변수는 없었다. 본 연구의 평균 나이, 키, 몸무게을 넣어 구한 추정정상치를 비교해보면 남자에서는 본연구의 FVC, FEV1 값이 다른 연구의 추정치에 비해 매우 낮은 값을 보이고 있으나 여자의 FVC, FEV1 값은 미국에서 고령의 흑인을 대상으로한 연구와 각각 비슷하거나 약간 높은값을 보였다. 결 론: 일부 농촌에서 50세 이상 건강인군에서 나이, 키, 몸무게를 독립변수로 한 노력성호기곡선을 이용한 폐활량측정법 검사지표들의 추정정상치를 산출하는 회귀방정식을 구하였다. 본 연구의 추정정상치들은 기존의 국내 연구에서의 추정정상치에 비해 낮은 값을 보이고 있다. 고령층 인구집단을 대상으로 ATS의 권고 기준에 합당한 폐활량 측정법 검사지표들의 추정 정상치를 구하는 연구들이 앞으로 더 필요하리라 생각된다.

본 연구는 10 주 동안 건강한 20대 성인 남녀 14명을 대상으로 D-리보오스 함유 비율이 다른 설탕 (D-리보오스 5%, 10%, 14% 함유) 섭취가 혈당 반응과 GI에 미치는 영향을 분석하여 혈당 저감화 효과를 확인하고자 하였다. 설탕과 D-리보오스함유 설탕의 혈당반응값을 비교하였을 때 D-리보오스 함유 설탕인 RB5, RB10, RB14 순으로 낮아졌으며 RB10, RB14는 설탕에 비해 유의적으로 낮은 혈당반응값을 보였다. 백설탕, RB5, RB10, RB14의 GI는 각각 67.39, 67.07, 47.57, 45.62로 설탕과 RB5는 중 GI 식품으로, RB10과 RB14는 저 GI 식품으로 분류되었으며, RB10, RB14의 GI는 설탕과 RB5의 GI에 비해 유의적으로 낮았다. 혈당 변화에 따른 Cmax를 보면 포도당 61.73 mg/dL에 비해 RB5, RB10, RB14가 각각 49.43 mg/dL, 37.25 mg/dL, 35.15 mg/dL로 유의적으로낮았으나, 설탕의 Cmax 58.18 mg/dL과 비교 시 RB10, RB14의 Cmax는 유의적으로 낮았으나, RB5와는 유의적인 차이를 보이지 않았다. 따라서 D-리보오스 함유 설탕의 혈당 상승 억제 효과는 D-리보오스를 5% 함유 시 보다는 D-리보오스를 10% 이상 함유할 때 더 효과적인 것으로 나타났다. 그러나 D-리보오스를 10%, 14% 함유한 설탕의 GI값과 혈당 변화율이 유사하게 나타나고 있으므로 D-리보오스 14% 함유보다는 D-리보오스 10% 함유하는 것이 혈당 저감화 효과 및 비용적인 측면을 고려할 때 기능성 설탕의 비율로 더 적절할 것으로 사료된다.
