Dietary components can modulate stress, inflammatory indicators, and health risk. This study examined the relationship among diet, metabolic disease risk, and perceived stress in Korean adult females using the 2017-2018 Korea National Health and Nutrition Examination Survey. A total of 4,353 adult women aged 19-64 years were classified into four groups according to perceived stress level: very high stress group (VHSG, n=225), high stress group (HSG, n=1,079), moderate stress group (MSG, n=2,532), and low stress group (LSG, n=517). Data collection included the sociodemographics, anthropometrics, blood profile, and dietary survey. After adjusting for covariates, those in the VHSG had a higher body mass index (p=0.013) and obesity rate (p=0.053) with a shorter sleep time than the LSG group. The VHSG also tended to have a higher plasma LDL-cholesterol, hsC-reactive protein and lower levels of HDL-cholesterol, vitamin A, and vitamin E than the low stress group. High stress subjects demonstrated increased breakfast skipping frequency (p<0.0001), decreased fiber intake (p=0.001), potassium (p=0.041), and vitamin A (p=0.011) than the low stress ones. Therefore the perceived stress level was associated with the inflammatory indicators, obesity, and lack of anti-inflammatory or antioxidant nutrients. The dietary components may be an important mediator of stress and metabolic disease.

Functional foods for health are often consumed among adolescents. To investigate functional food usage, this study surveyed 326 students aged 14-16. 56.3% of the subjects answered that they were interested in health. More than 76% of the subjects thought themselves to be very healthy. Users of functional foods made up 56.7%, and among all types of functional food, probiotic supplements were taken most frequently, followed by nutritional supplements>red ginseng products>enzyme containing products. Most users of functional food got the information on functional food through family (71.3%). 50.3% of users experienced the effectiveness of the functional food when they supplemented. After use, repurchase intent was 58.1%. In order to investigate the relationship between academic stress and functional food usage, groups were classified as stressful (n=124), intermediate (n=122), and low stress (n=84) according to self-perception about stress. There was no significant difference in the intake of functional foods according to academic stress. However, in the intermediate stress group, academic stress index was improved in the users of functional foods. In conclusion, the results of this study can be used to develop functional foods in the future, possibly helping to prepare nutrition education materials, reducing academic stress among adolescents with middle stress.

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.

This study examined the socioeconomic factors that affect self-rated health (SRH) in healthy adults, and the relationship of SRH to health-related habits, serum biochemical indices, and nutritional intakes. Subjects consisted of 1,154 healthy adults without any known disease, aged 19 to 65 years (average age of 36.7), whose information was obtained from the 2013 Korean National Health and Nutritional Examination Survey data. Of these subjects, 73 rated themselves as ‘very healthy,’ 460 indicated that they were ‘healthy,’ 568 self-identified as ‘ordinary’, and 53 put themselves in the ‘unhealthy’ category. The proportion of subjects who chose ‘unhealthy’ was significantly increased with higher frequencies of disruptions in their daily lives (p<0.05), regret after drinking (p<0.05), smoking (p<0.001), and higher levels of stress (p<0.001). On the other hand, the proportion of subjects reported as ‘very healthy’ was significantly higher with regular intense (p<0.001) or moderate physical activities (p<0.05), regular walking (p<0.05), a perception of being ‘normal’ in their body image (p<0.01), a decrease of body weight more than 3 kg in the past year (p<0.05), and without risk factors for metabolic syndrome (p<0.05). Serum triglyceride level was lower, and 25-(OH) vitamin D content was significantly higher, in the ‘very healthy’ group as compared to the ‘unhealthy’ group (p<0.05). Dietary fiber and vitamin C intakes were significantly higher in the ‘very healthy’ group than ‘unhealthy’ group (p<0.05). The overall results suggest that a healthy lifestyle, including regular exercise, non-smoking, good stress management, and higher intakes of fiber and vitamin C, may be potential factors that affect one’s positive perception of health.

The purpose of this study was to estimate the relationships between dietary factors and the stress perception levels of College students. A survey was conducted in June, 2010, targeting 332 college students in Gwangju. General environmental factors, stress perception levels, dietary behaviors, and dietary action guide performance of the subjects were evaluated by questionnaire, and food intakes was determined by the 24-hour recall method. The results are summarized as follows.: The score of frequency experiencing was 45.1±16.9 for male students, and 47.0±16.7 for female students. The importance scores were 50.8±18.5 for males, and 53.3±18.7 for females. The total score for dietary action guide performance was 39.6±7.2 for males and 40.6±6.5 for females. Nutrient intake levels were evaluated based on dietary reference intake (DRI), revealing energy intakes to be 68.5% EER in males and 73.9% in females. The mean intakes of nutrient were 54.2% RI for calcium, 73.6% RI for riboflavin, and 51.2% RI for vitamin C but 203.6% AI for sodium, which indicates an imbalance in nutrient intake. Analysis of the correlations between stress perception levels and dietary factors, scholarship achievements, financial problems, future problems, value senses, and family relationships revealed significant correlations with general environment factors, dietary behaviors, Dietary action guide performance, and nutrient intakes (p＜0.05). The higher the stress perception levels of the students, the higher the energy, coffee and alcohol intake, which predicts that appropriate stress control in college students will lead to better dietary habits. It is expected that the results above will be used as basic data for the development of proper nutrition education programs and stress control strategies.

This paper reviewed the relationship between perceived organizational justice(distributive justice, procedural justice, interactional justice) and job stress, and the moderating effect of trust(organizational trust and superior trust). Based on the responses from 176 employees, the results of multiple regression analysis appeared as follow; 1) Distributive justice and interactional justice effect negatively on job stress, but procedural justice does not effect on job stress. 2) While organizational trust and superior trust are stronger, interactional justice effect less negatively on job stress. When interactional justice is higher, job stress is lower in high trust level than in low trust level.

This study investigated the interrelations among acculturative stress, recognition, preference and eating frequency of Korean traditional food by Chinese students in Korea. The acculturative stress score was 3.06±0.32, ‘homesickness’ score was the highest (3.92±0.62) and ‘guiltscore’ score was the lowest (2.28±1.04). The rate of preferred for Korean food was low (20.5%). The places for eating Korean food were ‘restaurant’ (49.6%) and ‘school cafeteria’ (41.1%). The cooking experience regarding Korean food was 45.0% and they had cooked ‘Bulgogi’ (26.7%) and ‘Bibimbap’ (21.9%). The recognition score for Korean traditional food was 0.70±0.27. The preference score for Korean traditional food was 3.14±0.54, and the favorite foods were ‘Galbi’ and ‘Galbitang’ while ‘Ggakdugi’ was the lowest. The eating frequency for Korean traditional food was 2.15±0.82, and ‘Baechukimchi’ and ‘Bibimbap’ were comparatively high. The acculturative stress showed no correlation with the recognition, preference and eating frequency of Korean traditional food. The recognition of Korean traditional food correlated positively with the eating frequency (r=0.175, p<0.05). The preference of Korean traditional food had a significant effect on eating frequency (r=0.274, p<0.001), and the highest positive correlation was shown in ‘Ddeokbokki’ (r=0.470). The explanation power (R2) of recognition and preference on eating frequency was 0.098. This study showed the interrelations among recognition, preference, and eating frequency of Korean traditional food except for acculturative stress.

목적: 본 연구의 목적은 생리조절과 인지조절 심리기술훈련이 시합 스트레스 상황에서 선수들의 심리 및 동기체 계에 영향을 미치는 방식을 전두엽 좌우뇌 비대칭을 통해 조사하는 것이다. 방법: 연구대상자는 대학 남자 축구 선수 30명으로, 생리조절군 8명, 인지조절군 8명, 통제군에 14명씩 무작위 할당되었다. 심리기술훈련은 3주간 단 체훈련 3회기, 개인상담 3회기로 총 6회기가 진행되었다. 심리기술훈련 전과 후 휴식과 스트레스 회상 조건에서 심리상태와 전두엽 좌우뇌 비대칭값(Frontal EEG Asymmetry Score: FAS)이 측정되었다. 결과: 스트레스 조건에서 측정된 불안, 스트레스는 생리조절, 인지조절 집단 모두 훈련 전보다 후에 감소하였으나, 통제집단에서는 차이가 없었다. FAS 분석결과, 생리조절군의 FAS는 훈련 후 Fp2의 활성화 감소에 의해 음(-)의 방향으로 하락한 반면, 인지조절군의 FAS는 훈련 후 Fp2의 활성화 증가에 의해 양(+)의 방향으로 상승하였다. 이상적인 심리상태 유도를 위해, 생리조절훈련은 철회동기체계를 작동시켜 스트레스 상황을 회피하는 방식을, 인지조절 훈련은 철회 동기를 감소시켜 상황에 대한 적극대처 방식으로의 전환을 보였다. 결론: 본 연구는 심리기술훈련의 유형과 방식에 따라 심리변화를 유도하는 과정과 동기체계에 차이가 있을 수 있음을 확인하였다.
