Purpose: This study aimed to examine the effects of interpersonal relationship ability, job stress, and stress coping type on the turnover intention of nurses in the early stage of their careers. Methods: Data were collected from 136 early stage nurses from two general hospitals and one tertiary hospital in Chungbuk province. An early stage nurse was defined as the nurse with a work experience of 3 to 36 months. The collected data were analyzed using independent t-test, one-way ANOVA, Mann-Whitney U test, Person's correlation coefficient, and stepwise multiple regression. Results: It was seen that turnover intention had a negative correlation with interpersonal competency (r=-.20, p=.020) and a positive correlation with job stress (r=.56, p<.001). Job stress due to work over load, inadequate compensation and working environment, interpersonal relationship ability, and length of clinical career were significant factors influencing turnover intention (p<.05). These variables explained for 50.4% of the variance in turnover intention. Conclusion: It is necessary to develop an interpersonal relationship ability improvement program to decrease turnover intention among early stage nurses by helping them to successfully adapt to their job. Moreover, it is important to bring about continuous improvements in terms of provision of adequate workload and appropriate rewards, and creation of a suitable work environment to reduce the job stress of early stage nurses.

Background : The present study was performed to examine the genotype distribution of α-adducin Gly460-〉Trp single nucleotide polymorphism in Korean hypertensive patients. The effects of sodium intake level on the relationship between α-adducin Gly460Trp polymorphism and the blood pressure was also investigated.Methods : Sixty-five hypertensive patients were genotyped for α-adducin Gly460Trp polymorphism by using TaqMan polymerase chain reaction method. Sodium intake level of individual subjects were determined by a dietary questionnaire. These variables were compared with systolic- and diastolic blood pressure levels of the study subjects.Results : The frequencies of genotypes in the study subjects were 26.2% in Gly/Gly, 40% in Gly/Trp, and 33.8% in Trp/Trp, and the frequency of the Trp allele was 54%. All blood pressure values were not significantly different among three genotypes. No association was found among genotypes and blood pressure values with high- or low- dietary sodium intake levels.Conclusion : The present results indicate the absence of effect of α-adducin Gly460Trp polymorphism on blood pressure values in Korean hypertensive patients. However, high frequency of salt-sensitive Trp allele in Korean hypertensives, compared to Caucasians, suggests that this polymorphism may increase the prevalence of hypertension in Korean. Subsequent case-control study is needed to further understand the effect of α-adducin polymorphism and sodium intake levels on blood pressure levels in a Korean population. 연구배경 : 고혈압 환자를 대상으로 한국인에서 소금민감도에 관련된 α-adducin 유전자의 Gly460Trp 단일염기다형성 분포를 조사하고, 나트륨의 섭취 수준에 따라 α-adducin Gly460Trp 유전자 다형성이 혈압에 미치는 영향에 차이가 있는지 알아보고자 하였다.방법 : 2004년 10월부터 11월까지 일개 대학병원에 내원한 고혈압 환자 65명을 대상으로 하였다. α-adducin Gly460Trp 유전자 다형성을 TaqMan polymerase chain reaction을 통해 분석하였고, 나트륨에 대한 식이 설문 조사를 통해 나트륨 섭취량을 추정한 후, 이들 변수들과 수축기 및 이완기 혈압과의 관계를 비교·분석하였다.결 과 :α-adducin 유전자형 분포는 Gly/Trp형이 전체의 40%로 가장 많았으며 그 다음으로 Trp/Trp형 33.8%, Gly/Gly형 26.2%의 순으로, Trp allele를 가진 빈도가 54%인 것으로 나타났다. 각 유전자형별로 수축기 혈압과 이완기 혈압을 비교했을 때 통계적으로 유의한 차이는 없었다. 또한 나트륨 섭취 수준에 따라 대상자를 두 그룹으로 나누어 비교했을 때, 각 그룹에서 유전자형에 따른 수축기 및 이완기 혈압이 통계적으로 유의한 차이를 보이지 않았다.결 론 : 고혈압 환자에서 α-adducin Gly460Trp 유전자 다형성은 혈압 변화에 유의적인 영향 요인이 아닌 것으로 보인다. 하지만, 본 연구 대상자에서 백인에 비해 소금민감도 유발 allele인 Trp allele의 빈도가 매우 높은 것은 α-adducin Gly460Trp 유전자 다형성이 한국인의 고혈압 발생 단계에 있어 주요 인자가 될 수 있음을 시사한다.추가적인 환자-대조군 연구를 통한 α-adducin Gly460Trp 유전자 다형성과 나트륨 섭취의 상호 작용이 한국인의 고혈압 발생에 미치는 영향에 이해가 필요할 것으로 사료된다.

Background The prevalence of atopic dermatitis is increasing. The purpose of this study was to examine the prevalence of atopic dermatitis and associated dietary factors in preschool children.Methods We obtained the data on 1,104 preschool children aged 3-6 years from 18 preschools in metropolitan area. Prevalence of atopic dermatitis were studied using a questionnaire made by the International Study of Asthma and Allergy in Childhood (ISAAC) committee. Dietary information was obtained by using mini dietary assessment. All questions were answered by the parent of the study subjects.Results "Atopic dermatitis ever " was reported in 30.5% of the children. Prevalence of the current atopic dermatitis was 23.2%. There was no difference in the prevalence according to sex, age, and living area. Current atopic dermatitis was associated with "Eat vegetables (besides kimchi) in every meal (OR=0.47, p〈0.001) ", "Eat meat, fish, egg, bean or tofu in every meal (OR=0.48, p〈0.01) " and "Eat a variety of foods (OR=0.57, p〈0.01) ".Conclusions We found a high prevalence of atopic dermatitis in 3 to 6-year old children living in metropolitan area. Dietary pattern such as eating vegetables in every meal, eating protein-rich food in every meal, and eating a variety of foods appears to be inversely related with the development of atopic dermatitis. 연구배경 아토피 피부염은 만성 알레르기성 피부 질환으로 최근 들어 유병률이 급증하는 것으로 알려져 있으나, 아토피 피부염이 주로 시작되는 유아기 어린이들을 대상으로 한 대규모 연구는 미비한 편이다. 본 연구에서는 유치원생을 대상으로 아토피 피부염 유병률과 이에 영향을 미치는 식생활 및 관련 요인을 알아보고자 하였다.방 법 서울과 경기 지역에서 임의로 선정된 18곳의 유치원생을 대상으로 보호자가 설문지에 기입하는 방식으로 조사를 실시하였다. 아토피 피부염 유병률은 한국어로 번역된 ISAAC (international study of allergy and asthma in childhood) 설문지를 이용하였고, 간이식생활진단표를 이용하여 식습관을 조사하였다. 조사 기간은 2006년 5월부터 7월까지 3개월간 시행되었으며 분석 대상자는 총 1,104명(남자 어린이: 546명, 여자 어린이 : 558명)이었다.결 과 전체 대상자 중 337명 (30.5%)이 태어나서 지금까지 아토피 피부염 증상을 경험한 적이 있는 것으로 파악되었고, 최근 12개월 동안 아토피 피부염 증상이 있었던 경우도 전체의 23.2%로 높게 나타났다. 한 달 가구 평균 소득이 높을수록 유병률이 낮게 나타났으며(p〈0.05, χ2-test), 성별, 나이, 조사 대상 거주지역에 따른 유병률에는 유의한 차이가 없는 것으로 나타났다. 아토피 피부염과 관련된 식생활 요인을 분석한 결과, 아토피 피부염군은 그렇지 않은 대상자들과 비교했을 때 “모든 음식을 골고루 섭취한다”, ”육류, 생선, 달걀, 콩, 두부 등으로 된 음식을 끼니마다 먹는다”, “김치 이외의 채소를 식사할 때마다 먹는다“ 의 문항에 대해 ”항상 그런 편이다“라고 답한 빈도가 낮은 것으로 나타났다(p〈0.05).결 론 수도권 일부에 거주하는 유치원생들에서 아토피 피부염 유병률이 매우 높음을 알 수 있었으며, 균형적인 식품의 섭취, 매 끼니 식사에서 단백질 함유 식품 및 채소류의 높은 섭취가 아토피 피부염에의 위험도를 감소시킬 수 있는 것으로 보인다.

The purpose of this study was to investigate the dietary factors associated with characteristics of attention deficit hyperactivity disorder (ADHD) in upper-grade elementary school students. The study subjects were 397 students, and 52% of total study subjects were boys. The risk for developing ADHD was assessed by using a DSM-IV questionnaire. Boy`s ADHD score was higher than that of girls (p<0.001). Subjects were divided into two groups according to the median of the ADHD score in boys and girls. The high ADHD score group showed higher frequency of skipping breakfast and a lower score for good dietary habits, as compared to the normal group. Further, the high ADHD score group showed higher frequency of processed food intake with lower frequency of vegetable intake, as compared to the normal group. These results suggest that undesirable eating habits and frequent intake of processed foods may be associated with higher risk of developing ADHD in elementary school students.

Increasing numbers of Korean adults, especially women, are adopting vegetarian diets for various reasons. In this study, the characteristics of vegetarianism among females residing in Seoul were examined. In addition, the dietary habits and eating behaviors between vegetarians and non-vegetarians were investigated. A total of 148 females (73 vegetarians, 75 non-vegetarians) were recruited and questionnaires regarding their demographic characteristics and eating habits were completed. The eating behavior and daily intake of food groups was assessed using the three factor eating questionnaire-R18 (TFEQ-R18) and food frequency questionnaire, respectively. The ages, BMI, education, and religious affiliation were not significantly different between the two groups. More than 30% of vegetarians had followed a vegetarian diet for longer than 24 months. The most common motivations for vegetarianism in study participants were ‘health or weight control’ (46.6%) followed by ‘environmental concerns or animal welfare’ (24.7%). Vegetarians had a lower intake of cereals, Kimchi, and soda, but a higher intake of potatoes and sweet potatoes, vegetables, mushrooms, seaweed, and fruits compared to non-vegetarians. Significant differences in eating behavior scores were also found between the two groups; in particular, vegetarians reported higher levels of restrained eating and emotional eating than non-vegetarians. Scores of uncontrolled eating, however, were not significantly different between the two groups. In conclusion, these results suggest that while vegetarianism is associated with healthy dietary habits, it is associated with restrained eating behaviors which may increase the risk of eating disorders in women.

청소년의 에너지 음료 섭취수준에 따른 식습관, 생활습관 및 정신건강 관련 특성: 제10-13차 청소년 건강행태 온라인 조사를 이용하여

Background: Energy drinks (EDs), functional beverages with high concentrations of caffeine, can cause health risks. This study examined the frequency of ED consumption and related factors in Korean adolescents. Methods: Data from the 10th-13th Korea Youth Risk Behavior Web-based Survey was used, and a total of 137,101 boys and 130,806 girls were included in the final analyses. Differences in ED consumption and associated factors were analyzed using the Rao-Scott chi-square test and a multivariate logistic regression analysis, reflecting of the complex sample design. Results: In total, 17.3% boys and 12.9% girls consumed EDs more than once a week (P<0.001). In particular, 24.2% of all high-school students in the 12th grade consumed more than three EDs a week. After adjusting for confounding factors, a multivariate logistic regression analysis indicated that higher ED consumption was significantly associated with a higher soda, sweet-drink, and fast food intake; skipping breakfast; a lower vegetable intake; depression; suicidal thoughts; sleep deprivation; and increased smoking and alcohol drinking. Conclusions: ED consumption is associated with undesirable dietary-, lifestyle-, and mental health-related behaviors, suggesting the need for appropriate nutrition education in adolescents. 연구배경: 본 연구는 우리나라 청소년에서 에너지 음료 섭취 실태와 이에 따른 영향 요인을 파악하고자 수행되었다. 방법: 제10-13차 청소년건강행태온라인조사의 원시자료를 통합하여 만 12-18세 남학생 137,101명, 여학생 130,806명을 대상으로 분석하였다. 교란변수를 통제한 후 에너지 음료섭취 빈도와 각 요인의 관련성을 파악하고자 다중 로지스틱회귀분석을 실시하였다. 결과: 에너지 음료를 주 1회 이상 섭취하는 대상자가 전체학생의 15.1% (남: 17.3%; 여: 12.9%)였으며, 특히, 고등학교 3학년 학생의 24.2%가 주 3회 이상 섭취하고 있었다. 에너지 음료 주 3회 이상 섭취군은 비섭취군에 비해 탄산음료, 단맛 음료, 패스트푸드 등의 섭취는 증가하고, 주 1-2회 섭취군의 채소 섭취는 감소하였다. 또한, 에너지 음료 섭취빈도는 우울이나 자살 생각의 증가와 수면시간과 수면의 질의유의적인 감소와 관련이 있었다. 이 밖에, 생활습관 요인으로는 흡연과 음주의 유의적인 증가와 관련이 있었다. 결론: 청소년의 에너지 음료 섭취는 바람직하지 않은 식습관, 생활습관 및 정신건강 악화와 관련될 수 있으므로, 청소년에서 에너지 음료를 분별 있게 섭취할 수 있도록 적절한 교육이 필요하다.

Purpose: This study examined the changes in the nutrient intake and the prevalences of obesity and metabolic syndrome according to the eating alone behavior in middle-aged men and women. Methods: The data from the 2013~2017 Korean National Health and Nutrition Examination Survey were analyzed. A total of 7,728 adults (3,404 male, 4,324 female) aged 40 ~64 years old were included. The subjects were classified into three groups according to the number of times eating alone per day (0, 1~2, and 3 times/day). Dietary data were collected by a 1-day 24-h recall. The nutrient intakes were compared among the three groups. Survey logistic regression analyses were conducted to examine the association of the eating alone behavior with obesity and metabolic syndrome, adjusting for the related confounding variables. Results: In men, eating alone was associated significantly with a lower intake of potassium (p-for-trend=0.048) and lower intake of calories from protein (p-for-trend=0.04). In women, the proportion of subjects consuming energy less than 75% of the estimated energy requirement (p=0.001) and less than the estimated adequate requirement of riboflavin (p<0.001) differed significantly according to the eating alone behavior. The eating alone behavior was positively associated with an increased risk of developing metabolic syndrome (p-for-trend=0.033), increased blood pressure (p-for-trend<0.001), and increased waist circumference (p-for-trend=0.004). On the other hand, in women, however, the eating alone behavior was associated with a decreased risks of developing obesity (p-for-trend=0.02). No association was found between the eating alone behavior and the risk of metabolic syndrome in women. Conclusion: These results suggest that the eating alone behavior is a risk factor for the development of metabolic syndrome in middle-aged Korean men.
