The purpose of this study was to investigate the relationship between frequency of coffee consumption, metabolic biomarkers, and nutrition intake in adult participants in the combined 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects (2,095 males and 3,297 females) were classified according to sex and frequency of coffee consumption (${\leq}1$ time/month, ${\geq}2$ times/month and ${\leq}6$ times/week, 1 time/day, 2 times/day, 3 times/day) using food frequency questionnaires. Nutrition intake was analyzed using 24 h recall data. The 3 times/day coffee consumption group had a significantly higher age, and frequency of smokers and drinkers compared to the ${\leq}1$ time/month coffee consumption group in both male and female participants. Males in the 3 times/day coffee consumption group had a significantly lower HDL-cholesterol level, but females had a higher waist circumference compared with the ${\leq}1$ time/month coffee consumption group. Males in the 3 times/day coffee consumption group had a significantly lower nutrient density of fiber, vitamin B2, vitamin C, calcium and phosphorus compared with the ${\leq}1$ time/month coffee intake group. Females in the 3 times/day coffee consumption group had a significantly higher nutrient density of fat and niacin, but lower nutrient density of carbohydrate, calcium, phosphorus, and iron compared with the ${\leq}1$ time/month coffee intake group. In males, the frequency of coffee consumption was not associated with the levels of metabolic biomarkers. In females, the frequency of coffee consumption was positively associated with diastolic blood pressure after adjustments for multiple confounding factors, including age, BMI, smoking status, alcohol consumption, physical activity and energy intake. Coffee consumption was associated with decreased diastolic blood pressure in females. These findings suggest the importance of an awareness of the association between coffee consumption and metabolic risk.

The purpose of this study was to evaluate the sodium-related dietary attitudes, behaviors, and nutritional knowledge in university students according to the practice of dietary guidelines for Koreans established by the Ministry of Health and Welfare, Republic of Korea. Based on the total practice score related to the dietary guidelines (PDG), we classified subjects into a "low practice of the dietary guidelines (LPDG)" group (n=94, male=43, female=51) (total score of PDG ${\leq}13$) and a "high practice of the dietary guidelines (HPDG)" group (n=56, male=32, female=24) (total score of PDG >13). Subjects were asked about general characteristics, lifestyle, salt-related dietary attitudes, behaviors, and nutritional knowledge using a questionnaire. The LPDG group had more subjects who were breakfast skippers (p<0.001) compared to the HPDG group. The LPDG group (31.26) had a significantly lower score in terms of salt-related dietary attitudes compared to the HPDG group (33.77) (p=0.0042). The score for salt-related dietary attitudes was significantly higher in the HPDG (32.52) group than in the LPDG (29.91) group (p=0.0041). There was no significant difference in the total score for salt-related nutrition knowledge between the groups. The correlation analysis indicated that the dietary guidelines practice score had a positive correlation with the salt-related dietary attitude score (r=0.3593, p<0.0001) and the dietary attitude score (r=0.3443, p<0.0001) after adjustments for sex. These results show that the degree of adherence to the dietary guidelines for adults may be related to sodium-related dietary attitudes, behaviors, and nutrition knowledge.

The purpose of this study was to compare the nutritional meal variety of self-selected diet in Korean adults with different age groups. Subjects were recruited and divided info three groups according to the age, which included 20$\sim$49 yrs group(n=129), 50$\sim$64 yrs group(n=134), and $\geq$65 yrs group(n핀8). Subjects were interviewed using a general questionnaire and 24-hour recall method for dietary intake. The average age of the subjects were 40.8 years for 20$\sim$49 yrs group, 57.1 years for 50$\sim$64 yrs group, and 70.7 years for $\geq$65 yrs group. The daily food, energy and nutrient intakes ere decreased with increment of age. The intakes of vitamin B2, folate, vitamin C, and calcium were under the 75% of RIs, respectively. The numbers of food items in diet of 20$\sim$49 yrs group, 50$\sim$64 yrs group and $\geq$65 yrs group were 14.2, 17.0, 13.2 for breakfast, 16.3, 15.4, 13.5 for lunch, 13.1, 15.1, 13.9 for dinner, respectively. And the numbers of dish items in these groups were 4.0, 4.6, 3.8 for breakfast, 4.4, 4.2, 3.9 for lunch, 4.0, 4.0, 3.6 for dinner, respectively. The KDDS of 20$\sim$49 yrs group, 50$\sim$64 yrs group and $\geq$65 yrs group were 3.9, 3.6 and 3.4 respectively and there was significant difference(p<0.001). According to these results, it could be suggested aged group take a undesirable meal in the right of insufficient nutrient intake to DRIs and lower food and dish items, and therefore showing a strong need of proper dietary management for them.

The purpose of this study was to investigate the relation between bone mineral density and nutrient intake among normal and obese elementary students. Each subject was assigned to one of such as normal (n = 69) and obese groups (n = 94) according to their obesity indices. And they were asked for general characteristics, dietary habits and nutrient intakes using questionnaires and 24-hr recall method. They measured the sound of speed (SOS) of calcaneus using quantitative ultrasound. The averages age of the subjects were 10.6 years in normal and 10.7 years in obese group. The averages weight (p < 0.001) and obesity index (p < 0.001) of the normal group were significantly lower than those of the obese group. In dietary habits, the obese group in boys was the higher skipped breakfast than normal group (p < 0.01). The plant calcium intake of obesity in girls was lower than those of normal group (p < 0.05). The SOS in the calcaneus was 1697.6 m/s in the obese group and 1763.7 m/s in the normal group (p < 0.01). The SOS in the calcaneus was negatively correlated to weight (p < 0.01), obesity index (p < 0.001) and percent of body fat (p < 0.01). Also the SOS in the calcaneus was positively correlated plant calcium intake (p < 0.05). In conclusion, the excessive increase of weight and percent of body fat in elementary students appeared to have negative impact to bone health. And based on these results, further studies on the effects on bone mineral density of obese and nutrient intakes in needed for proper bone health.

In this study, a survey was conducted among university students (119 men and 134 women) in Chungbuk province using questionnaires to investigate the variables and eating patterns related to the use of food delivery apps. A survey was conducted from March 22, 2019 to April 3, 2019. Of the total respondents, 77.2% reported that they had ordered food at least once using food delivery apps on smartphones. Further, 63.3% of the total subjects had ordered food delivery through smartphone apps once or twice a month, and the most preferred cuisine for food delivery was fast food, followed by Bunsik (Korean street food/snack), western food, and Chinese food. The average satisfaction scorefor food delivery apps was 3.8 points, and the satisfaction score was the highest with the convenient ordering process (4.0), followed by good taste (3.9) and good portion (3.8). The subjects who used smartphone food delivery apps three times or more a month showed a significantly higher frequency of instant food intake (p=0.0132), dining out (p=0.0282), and late-night eating (p=0.0047) than the subjects who ordered food using delivery apps less than three times a month. In conclusion, these study results may be applied as baseline data for dietary education among university students.

임신성 당뇨관리와 출산 후 비만 예방을 위한 운동 요법

배윤정(Bae, Yun-Jung),손지은(Sun, Jee-Un),이대택(Lee, Dae-Taek) 대한운동학회 2007 아시아 운동학 학술지 Vol.9 No.2

최근 여성들은 출산연령의 증가와 사회적 활동 참여로 인한 스트레스의 증가, 운동부족으로 인한 과체중 등의 원인으로 임신성 당뇨의 발병률은 크게 증가하고 있다. 실제로 임신성 당뇨의 발병률이 1994년도에 조사된 발병률에 비해 2002년도에는 약 두 배 가까이 증가한 것을 알 수 있다. 임신 동안에는 고인슐린혈증 상태가 나타나고 인슐린의 민감도가 떨어지게 된다. 임신성 당뇨란 임신동안에 글루코스의 불내성이 시작되었거나, 이를 처음으로 신체가 인지한 상태를 말한다. 이것은 출산 후에는 대부분 회복되기도 하지만, 출산 이후에도 제 2형 당뇨로 진행될 위험이 있다. 임신기간 동안에 일일 20분 정도의 운동을 중정도의 강도로 주 3일씩 규칙적으로 실시한다면 체중 조절의 효과 뿐 만 아니라 혈당의 조절능력도 향상 시키게 된다. 임신 중 운동의 효과에 대해서는 단기간의 운동에 대한 효과와 장기간의 운동에 대한 효과에 대한 선행연구들이 있다. 임신성 당뇨환자가 운동을 실시할 경우 고려해야 할 사항은 매우 많다. 특히 임신부들에게 운동은 비정상적 출혈이나 저체중아 출산과 같은 부작용 초래할 수 있기 때문에 특히 주의 깊게 관찰되어야 한다. 출산 후 체중관리는 임신성 당뇨가 제 2형 당뇨로 진행될 가능성과 산후 비만을 예방하는데 무엇보다도 중요하다. 임신성 당뇨에 관한 운동의 효과를 검증함에 있어서 이후의 연구에서는 운동 환경에 대한 적정 온도, 수분의 섭취, 인슐린처치와의 상호작용, 준비, 정리운동의 프로토콜 등의 구체적인 검토가 필요하다. Recently, widely increased rate of gestational diabetes mellitus because of many women participated social work, increased stress level and lack of exercise, thus lated labor period. As the prevalence of type 2 diabetes increases worldwide, more women are developing diabetes in their childbearing years. The incidence of GDM doubled between the 1994 and 2002. Pregnancy is characterized by a hyperinsulinemic state and a decrease in insulin sensitivity. Gestational diabetes mellitus is defined as glucose intolerance that begins, or is first recognized, during pregnancy. Most case, gestational diabetes recovered postpartum period, but have shown future type 2 diabetes. Moderate exercise( 20minutes, 3days/week) are effective in weight control and glucose control. Acute exertion and exercise training have well-characterized effects on control of blood glucose that may all have a salutary effect on glucose intolerance of pregnancy and GDM. In patients associated with wide range of complication. For the mother, gestational diabetes increases the risk of abnormal bleeding, and poor fatal growth. Weight control during postpartum very important that prevention for postpartum obesity and future type 2 diabetes. In the future study need to exercise temperature, hydration level, exercise protocol for each pregnancy period and insulin therapy.

배윤정(Bae, Yun-Jung) 한국영양학회 2016 Journal of Nutrition and Health Vol.49 No.6

본 연구에서는 국가 단위 대규모의 데이터 (2013~2014년 국민건강영양조사 자료)를 활용하여 성인 남녀별 외식으로부터 섭취하는 열량의 사분위에 따른 군간 일반사항, 영양소 및 식품군별 섭취 상태를 분석하고, 영양소별 섭취밀도 및 영양의 질적 지수를 평가하였으며, 그 결과는 다음과 같다. 남녀 모두에서 외식을 통한 열량의 섭취 정도가 높은 성인일수록 연령이 유의적으로 낮았고, 음주 빈도, 가구소득 및 교육수준이 유의적으로 높은 결과를 보였다. 또한 외식을 통한 열량 섭취가 높은 남녀 성인에서 전체 열량섭취량 및 지방의 섭취 밀도는 높게 나타난 반면, 식이섬유소, 비타민 B1, 칼슘, 인, 칼륨 및 철과 같은 미량 영양소의 섭취 밀도는 유의적으로 낮은 결과를 보였으며, 비타민 B1, 칼슘, 인 및 철의 INQ와 같은 식사의 질 지수 역시 유의적으로 낮게 나타났다. 식품군별 섭취 비율을 분석시 남녀모두에서 외식을 통한 열량 섭취가 높은 군에서 육류, 음료 및 주류의 섭취 비율이 유의적으로 높았던 반면, 곡류, 채소류, 어패류 및 해조류의 섭취 비율은 유의적으로 낮게 나타났다. 이와 같은 결과는 식생활에서 외식이 차지하는 비율이 계속적으로 증가하고 있는 현 시점에서, 외식을 많이 하는 대상자와 관련된 전반적인 영양소 및 식품군별 섭취상태를 파악할 수 있는 기초자료로써 활용될 것으로 예상된다. Purpose: The objective of the present study was to evaluate nutrient and food group intakes in Korean adults according to energy intake from eating-out. Methods: This study was a cross-sectional study based on the 2013~2014 Korea National Health and Nutritional Examination Survey, and study subjects were 5,186 males (2,151) and females (3,035) aged 19~64 years. Energy intake from eating-out was analyzed using the 24-hour dietary recall method, and groups were classified by quartile according to energy intake from eating-out. Results: Subjects who had more energy intake from eating-out tended to be younger, highly educated, have a higher income, and have higher alcohol consumption. Total energy intake and fat intake density of the highest quartile group of energy intake from eating-out were higher than those of the other groups. However, fiber, vitamin B1, calcium, phosphorus, potassium, and iron intake density levels were significantly lower in the highest quartile group of energy intake from eating-out. The highest quartile group of energy intake from eating-out consumed significantly more meat and beverages compared to the other groups. In addition, regarding diet quality (Index of nutritional quality), significantly lower vitamin B1, calcium, phosphorus, and iron levels were observed in the highest quartile group of energy intake from eating-out compared to those in the other groups. Conclusion: In conclusion, in Korean adults, consumption of eating-out decreased dietary quality, including vitamin B1, calcium, phosphorus, and iron levels. Further studies are needed to confirm these findings.

Stress has been associated with poor eating behavior and diet quality. Yet, the relationship between nutrient and food intake and perceived stress in Korean female adults has not been validated. The purpose of this study is to identify the relationship between nutrient and food intake and perceived stress in Korean female adults. This is a cross-sectional study based on the 2014-2015 Korean National Health and Nutritional Examination Survey data. This study investigated 2,010 female adults age 19~64. In this study, according to subjects' perceived stress, we classified subjects into very low-stress recognition group (VLSRG) (n=211), low-stress recognition group (VSRG) (n=1,223), high-stress recognition group (HSRG) (n=488) and very high-stress recognition group (VHSRG) (n=88). Daily nutrients and food group intake, food groups consumed (Dietary Diversity Score, DDS) were analyzed using data from the 24-recall method. The VHSRG had a larger proportion of subjects that were younger (p<0.0001), single (p<0.0001) and smokers (p<0.0001) compared to the VLSRG. Energy and food intake did not differ between the four groups. Percentage of subjects with protein (p=0.0322), vitamin A (p=0.0364) and vitamin C (p=0.0115) intake lower than the EAR (estimated average requirement) in the VHSRG were significantly lowest in the four groups. Also, food intake percentage from fruits and seaweed groups in the VHSRG were lower than other groups (p=0.0034, p=0.0015). DDS in the VHSRG (3.87) was significantly lowest in the four groups (p=0.0022). Results suggest that perceived stress in Korean female adults may by significant to consider in nutritional education programs.

The purpose of this study was to examine the dietary behaviors, processed food preferences, and awareness levels of nutrition labels among female university students living in middle region by breakfast eating. A total of 243 students (breakfast eating group: 153, breakfast skipping group: 90) were surveyed from April to May of 2011. The results are summarized as follows: Skipping breakfast (SB) group had a significantly higher frequency of skipping lunch and dinner compared with the eating breakfast (EB) group (P<0.05, P<0.01, respectively). In the EB group, food labels were identified sometimes (31.8%), frequently (29.1%), and rarely (28.5%). In the SB group, food labels were identified rarely (33.3%), sometimes (27.8%), and frequently (26.7%). The EB group used food labels for comparing price and weight of products more frequently than the SB group (P<0.05). In the EB group, nutrition labels were identified sometimes (38.0%), frequently (28.1%), and rarely (24.8%). In the SB group, nutrition labels were identified rarely (32.6%), sometimes (30.3%), and frequently (21.4%). The EB group used food labels for identifying nutrient contents more often and for weight control more less than the SB group (P<0.05, P<0.05, respectively). The main reason for not identifying nutrition label of the processed foods was ``not being interested (55.5%)`` in the SB group (P <0.05). Therefore, education programs that emphasize the importance of eating breakfast, and reading food and nutrition labels need to be developed for university students.

일부 한국 여성에 있어 칼륨과 단백질의 섭취량에 의한 NEAP(net rate of endogenous noncarbonic acid production)와 골밀도와의 관련성

배윤정(Yun-Jung Bae),최미경(Mi-Kyeong Choi),김미현(Mi-Hyun Kim),김은영(Eun-Young Kim),이주연(Joo-Yeon Lee),승정자(Chung-Ja Sung) 한국식품영양과학회 2006 한국식품영양과학회지 Vol.35 No.9

단백질과 칼륨의 섭취량으로 산출한 NEAP와 여성의 골밀도 및 골대사지표와의 관련성을 알아보기 위하여 18~81세의 여성 276명을 대상으로 설문조사와 식사섭취조사, 요추와 대퇴경부의 골밀도 측정, 소변의 디옥시피리디놀린을 분석한 결과는 다음과 같다. 대상자들의 NEAP 수준은 요추골밀도(p<0.05)와 유의적인 음의 상관성을 보였고 대퇴경부골밀도와도 유의적인 수준은 아니었으나 음의 상관성을 보였다. NEAP의 수준에 따라 대상자를 4분위수로 분류하고 연령, 신장, 체중의 차이를 보정하여 골밀도를 비교하였을 때 NEAP 수준이 가장 낮은 군의 요추 및 대퇴경부 골밀도가 가장 높았으나 유의적인 차이를 보이지는 않았다. 또한 단백질의 섭취량에 따른 골밀도의 4분위수 분석결과 단백질의 섭취량이 증가함에 따라 요추 골밀도가 감소하였다(p<0.05). 이상의 연구결과를 통하여 체내에서 알칼리를 생성하는 칼륨의 섭취증가와 체내에서 산을 생성하는 단백질의 섭취감소를 통한 체내 산도의 감소가 여성의 골밀도와 긍정적인 관련성을 나타낼 수 있음이 제시되었다. 따라서 칼슘섭취의 부족문제가 좀처럼 해결되고 있지 않은 우리나라의 식생활에서 골용해와 칼슘의 배설을 줄임으로써 골격건강을 유지할 수 있는 방안으로 단백질의 과잉섭취를 제한하고 체내알칼리를 형성할 수 있는 무기질이 풍부한 식품의 섭취를 늘일 수 있도록 하는 식사지침의 마련이 필요하다고 생각된다. 또한 본 연구에서는 골밀도에 긍정적인 영향을 미치는 체내 알칼리성 유도 영양소를 칼륨으로만 한정했지만, 마그네슘이나 칼슘 등도 체내 알칼리성에 영향을 미치는 요인이기 때문에 다양한 알칼리성 영양소의 섭취가 골밀도에 미치는 영향에 대한 추후 연구가 요구된다. The purpose of this study was to investigate the relation between NEAP (net rate of endogenous noncarbonic acid production) from dietary potassium and protein intakes, and bone mineral density and urinary deoxypyridinoline (DPD) in Korean women. The subjects were 276 women aged 18~81, and they were asked about general characteristics and nutrient intake using 24-hr recall method. Also, their bone mineral density of spine and femoral neck were measured using DEXA. Urinary DPD analysis was done in 106 postmenopausal women. The average energy, protein and potassium intake were 1503.0 kcal, 57.7 g and 60.8 mEq, respectively. Mean NEAP [54.5×{protein intake (g)/potassium intake (mEq)}-10.2] was 44.6. NEAP showed a significantly negative correlation with spine bone mineral density of the subjects after controlling for confounding factors (age, height and weight) (p<0.05). The lowest quartile of protein intake had the highest spine bone mineral density after controlling for confounding factors (p<0.05). There was no significant correlation between urinary DPD and calculated NEAP. These results provided positive relation between a ratio of lower protein to higher potassium dietary intake and bone mineral density.
