Purpose: The purpose of this study was to estimate in∞me -related health inequalities among adolescent population across regions in Korea. Methods: Data of 8.456 adolescents from 1998. 2001. 2005. 2007 Korean Health and Nutrition Examination Survey were used for the analysis. True health status was proxied by self-rated health and overweight status. Per capita income was computed from household monthly average income adjusted by ∞nsumer price with base year 2005. Adolescent health in여ualities were estimated by Concentration Index (C]) across income and space. Results: III health score was related with age (P<0.0001l) gender (p=0.0155) and income (P<0.0001l) Negative relationship between income and ill-health indicated that higher income group tended to enjoy better health and less overweight. These evidences suggested ill health were accumulated on the economically disadvantaged adolescents. The size of health inequalities Oll-health score) were estimated as CI=-0.057 and CI=-0.030 across income groups and regions. respectively, Comparable measures of within region health disparities were also obseπed. Conclusion : Since health disparity among adolescent population was small compared to adult population, lessening adolescent health inequality could be a helpful way of mitigating health disparities in later stage. Considering life stage of adolescents. school system and I∞al communities could play important roles toward adolescent health distribution. Although health disparity between regions existed. health disparity within a region should not be neglected.

본 연구에서는 한국 성인의 비타민 E 섭취량과 기여식품군의 현황 및 추이를 확인하기 위하여 제1~6기 국민건강영양조사에 참여한 19세 이상 성인 69,665명의 24시간 회상 자료를 한국인 상용식품의 비타민 E 함량 데이터베이스와 연계하여 α-, β-, γ-, δ-토코페롤 및 비타민 E 섭취량을 추정하였다. 그 결과 비타민 E의 섭취량은 1998년도 이후 꾸준히 증가하였으며, 2013~2015년의 비타민 E 섭취량은 남성 7.5 mg α-TE/d, 여성 6.4 mg α-TE/d였음을 알 수 있었다. 각 식품군별 비타민 E 섭취 기여율을 산출하였을 때에는 채소류, 곡류, 난류 순으로 기여율이 높았고, 시간에 따른 추이를 보았을 때에는 채소류의 기여율은 감소하였고 난류의 기여율은 증가하였다. 2015 한국인 영양소 섭취기준을 이용해 본 연구에서 추정한 한국 성인의 비타민 E섭취량을 평가한 결과, 비타민 E의 평균 섭취량이 충분섭취량에 미치지 못하는 것으로 나타났다. 이러한 섭취 부족현상은 연령이 높고 교육수준 및 소득수준이 낮을수록 뚜렷하였다. 따라서 이러한 영양취약계층을 대상으로 비타민 E의 기능 및 급원식품을 교육할 필요성이 있다고 사료된다. 본 연구에서 체계적인 방법으로 추정한 한국 성인의 비타민 E 섭취량은 한국인 영양소 섭취기준의 개정을 위한 근거자료로 사용될 수 있을 것이나, 한국인 상용식품 내 다양한 형태의 비타민 E 함량을 분석하는 후속 연구가 수행되면, 더욱 정확한 비타민 E 섭취량 추정값을 얻을 수 있을 것이다. Purpose: The purpose of this study was to determine trends in dietary vitamin E intakes and contributing food groups among Korean adults. Methods: This study included 66,695 subjects aged ≥ 19 years who completed a nutrition survey as part of the Korea National Health and Nutrition Examination Survey (1998, 2001, 2005, 2007~2009, 2010~2012, 2013~2015). We estimated individual daily intakes of α-, β-, γ-, δ-tocopherol, and total vitamin E by linking food consumption data with a vitamin E database of commonly consumed foods. Results: Daily vitamin E intake significantly increased from 6.4 mg α-TE/d in 1998 to 7.7 mg α-TE/d in 2013~2015 (p for trend < 0.0001) among men as well as from 5.4 mg α-TE/d in 1998 to 6.5 mg α-TE/d in 2013~2015 among women (p for trend < 0.0001). However, the intake of vitamin E was lower than the adequate intake (AI) of Dietary Reference Intakes for Koreans 2015 (2015 KDRI). In 2013~2015, men consumed 6.5 mg/d of α-tocopherol, 0.5 mg/d of β-tocopherol, 6.0 mg/d of γ-tocopherol, and 3.9 mg/d of δ-tocopherol, whereas women consumed 5.7 mg/d of α-tocopherol, 0.4 mg/d of β-tocopherol, 4.8 mg/d of γ-tocopherol, and 2.8 mg/d of δ-tocopherol. The major food groups contributing to vitamin E intake were vegetables (men: 23.3%, women: 22.7%), grains (men: 14.5%, women: 13.9%), and eggs (men: 13.0%, women: 12.5%). Conclusion: This study provides scientific evidence for vitamin E intake in Korean adults. Since the current intake of vitamin E was lower than the reference intakes set by 2015 KDRI, dietary vitamin E intake should be monitored regularly among Korean adults.

안서은(Ahn, Seoeun),전신영(Jun, Shinyoung),강민지(Kang, Minji),신상아(Shin, Sangah),위경애(Wie, Gyung-Ah),백현욱(Baik, Hyun Wook),정효지(Joung, Hyojee) 한국영양학회 2017 Journal of Nutrition and Health Vol.50 No.4

Purpose: The purpose of this study was to examine the association between intake of antioxidant vitamins and prevalence of metabolic syndrome (MetS) among Korean adults. Methods: A total of 614 subjects aged 30~60 years were recruited from those who received a medical checkup at a general hospital in South Korea between 2009 and 2012. Presence of MetS was determined based on criteria issued by the NCEP ATP III. Intakes of antioxidant vitamins (vitamin A, retinol, carotenoids, vitamin C, and vitamin E) were estimated by combining 3-day diet records with an antioxidant vitamin database for common Korean foods. We used multiple logistic regression analysis to assess the association between dietary intakes of antioxidant vitamins and MetS. Results: Men in the highest tertile for retinol (OR = 0.40, 95% CI = 0.23~0.71, P for trend = 0.0009), carotenoids (OR = 0.57, 95% CI = 0.32~1.00, P for trend = 0.0470), and vitamin E (OR = 0.52, 95% CI = 0.30~0.92, P for trend = 0.0190) intakes had a lower likelihood of having Mets than those in the lowest tertile. The OR of high fasting blood glucose among men in the highest tertile for vitamin A (μg RE: OR = 0.55, 95% CI = 0.32~0.97, P for trend = 0.0417, μg RAE: OR = 0.52, 95% CI = 0.29~0.92, P for trend = 0.0211), carotenoids (OR = 0.41, 95% CI = 0.23~0.73, P for trend = 0.0036), and vitamin E (OR = 0.47, 95% CI = 0.26~0.82, P for trend = 0.0080) intakes was lower than those in the lowest tertile. In women, subjects in the highest tertile of retinol intakes had a lower prevalence of MetS than those in the lowest tertile group (OR = 0.55, 95% CI = 0.30~0.98). The OR for abdominal obesity was lower among women with the highest vitamin A (μg RE) intakes compared to those in the lowest tertile (OR = 0.51, 95% CI = 0.28~0.93, P for trend = 0.0293). Conclusion: These results suggest that dietary intakes of antioxidant vitamins might be associated with reduced risk of having MetS among Korean adults.

Effects of Pulsed Magnetic Field on the Flowing Red Blood Cells Using Microvascular Model

Jo, Yonghyeok,Ahn, Hyoje,Shin, Kyunghun,Lee, Hyunsook IEEE 2018 IEEE transactions on magnetics Vol.54 No.11

<P>We have investigated quantitatively the effects of pulsed magnetic field (PMF) stimulus on the changes of blood flow, aggregation of red blood cells (RBCs), and oxidative stress on RBCs in the micro-channel of <TEX>$15~\mu \text{m}$</TEX> in diameter, in order to understand rheological properties of RBC in the microcirculation system. Erythrocyte sedimentation rate analysis was applied to see the effect of PMF on RBCs aggregation. RBCs disaggregated after PMF stimulus were sedimented slowly compared to that before PMF. It is also observed that after PMF stimulus, aggregation of RBCs is almost loosened, and the velocity of RBCs is fast in the microvascular model. Changes in blood flow and deformation of RBCs were examined after inducing oxidative stress to the erythrocyte membrane in order to see how the magnetic field affects the oxygen transport capacity of RBCs. From our results, PMF stimulus is proposed to achieve improvement of RBCs aggregation, increase of blood velocity, and preventing RBCs from oxidative stress.</P>

The Change of Capillaroscopic Features under Pulsed Magnetic Field

Kyunghun Shin,Seunghwan Bang,Hyoje Ahn,Hyunsook Lee 한국자기학회 2019 Journal of Magnetics Vol.24 No.1

The purpose of present study is to observe the change in capillaroscopic features before and after pulsed magnetic field (PMF) stimulus: the number, shape, length of capillary loop, and diameters of efferent capillary, and images of capillary loop. Nailfold capillary microscopy was used to quantitatively estimate the change of morphological characteristics of the capillaries. Capillary blood flow is recorded using video camera recorded at a frame rate of 60fps attached to the microscope. The velocities of capillary blood cell were 441 ± 22 and 508 ± 20 ㎛/s, before and after PMF stimulus, respectively. For the nailfold capillary morphologies, compared to before PMF, the more clearly visible loops are arranged as well as the capillary loop lengthened after PMF stimulus. Also the numbers of capillary loop/mm increased after PMF stimulus. In addition, tortuous capillary turned to hairpin shaped loop and the number of tortuous and abnormal capillaries are reduced after PMF stimulus. Our results proved the PMF stimulus on the palm of left hand for 10 min. provide the improvement of capillary blood flow, and it decreases vascular resistance in the blood micro-circulatory system. In addition, our study suggested quantitative and qualitative parameters of the nailfold vasculature in order to elucidate the effect of PMF. For expanding our findings, we need to have more subjects across a wide spectrum of age and with microvascular abnormalities, such as scleroderma, dermatomyositis and related disorders.

본 연구는 한국 성인을 대상으로 한국인을 위한 식생활지침에 대한 인식 수준을 파악하고, 이러한 인식 수준이 인구사회학적 요인 및 생활습관에 따라 차이가 있는지 확인하고자 수행되었다. 식생활지침에 대한 인지도는 연령이 높고 (50–64세), 거주형태가 1인 가구이며, 신체활동 수준이 활동적이고, 외식빈도가 적고, 식생활 정보에 대한 관심이 높은 참여자에서 유의하게 높았으며, 식생활지침에 대한 이해도는 여성, 젊은 연령 (19–29세), 저체중/정상체중, 현재 비흡연자, 스스로의 식사의 질을 건강하다고 평가한 참여자, 식생활 정보에 대한 관심이 높은 참여자에서 유의하게 높았다. 식생활지침의 활용가능도는 연령이 높고 (50–64세), 신체활동 수준이 활동적이고, 스스로의 식사의 질을 건강하다고 평가했으며, 식생활 정보에 대한 관심이 높은 참여자에서 유의하게 높았다. 또한 식생활지침에 대한 인식 수준이 높은 참여자가 대부분의 영양소와 식품군을 더 중요하다고 평가했으며, 인식 수준에 상관없이 가공육류 및 기타 가공식품류, 음료류, 주류에 대한 중요도 점수가 낮았다. 이러한 결과는 식생활지침에 대한 인식과 활용을 증진시키기 위해선 다양한 인구사회학적 및 생활습관 요인에 대한 고려가 필요하며, 추후 식생활지침을 개정할 때에는 우리나라 국민의 식생활 트랜드를 반영할 필요가 있음을 시사한다. Purpose: This study aimed to investigate the perceptions of the dietary guidelines for Koreans (DGK) among Korean adults based on sociodemographic and lifestyle factors. Methods: A total of 514 Korean adults aged 19–64 years completed a self-administered online questionnaire assessing their perceptions of DGK, sociodemographic and lifestyle factors, and subjective assessments regarding the importance of 11 nutrients and 16 food groups. The differences in the perceptions of DGK according to the characteristics of the participants were analyzed using t-tests or ANOVA. Additionally, the differences in the subjective assessments of nutrients and food groups according to the perceptions of DGK were examined using t-tests. Results: The awareness of DGK was significantly higher among participants aged 50–64 years, living in single-person households, who were physically active, with a lower frequency of eating out, and with a higher interest in dietary information (p < 0.05 for all). The understanding of DGK was significantly higher among participants aged 19–29 years, females, individuals who were under or normal weight, non-smokers, those who selfevaluated their diet as healthy, and those with a high interest in dietary information (p < 0.05 for all). Additionally, the applicability of DGK was significantly higher among participants aged 50–64 years, who were physically active, who self-evaluated their diet as healthy, and who had a high interest in dietary information (p < 0.05 for all). Participants with a higher perception of DGK tended to attribute greater importance to most nutrients and food groups compared to those with a lower perception level. However, processed meat and foods, beverages, and alcoholic drinks consistently received lower importance ratings compared to other nutrients and food groups, regardless of the perception level. Conclusion: This research suggests that the perceptions of DGK among Korean adults may vary depending on sociodemographic and lifestyle factors. Consequently, there is a need to customize and diversify the methods for providing dietary guidelines.
