Sleep pattern disruptions have been reported to be associated with an increased risk of obesity. This study was performed to investigate the association between sleep quality and sleep duration with dietary consumption, psychological factors, and obesity in Korean adults. A total of 288 Korean men and women who visited a public health center were included in this study. Data on general characteristics, health-related habits, psychological symptoms, dietary intake, and sleep patterns (including quality and duration) were collected using self-report questionnaires. Approximately half of the included Korean adults experienced sleep of low quality and short duration. Subjects who reported short sleep durations had a significantly higher weight (P=0.015), body mass index (P<0.001), and prevalence of obesity (P=0.012) than those reporting proper sleep durations. After adjustment for covariates, subjects reporting short sleep durations consumed more dietary carbohydrates (P=0.043) and higher levels of perceived stress (P=0.001), depression (P=0.001), and anxiety (P<0.001) than subjects reporting proper sleep durations. However, obesity-related variables, dietary intake and psychosocial symptoms did not differ significantly by reported sleep quality. The results of this study demonstrated that sleep duration but not sleep quality was associated with dietary macronutrient intake and psychological symptoms, which might affect obesity.

본 연구는 사회적 문제로 대두되는 있는 치매를 예방하기 위한 접근방법으로 알츠가드(Alzguard)를 제안하고자 한다. 알츠가드는 치매의 전단계인 경도인지장애를 치료하여 치매를 예방할 수 있도록 하는 카카오톡 플랫폼 기반 대화형 디지털 테라퓨틱스이다. 디지털 테라퓨틱스는 디지털 매체를 통해 질병 관리가 가능한 치료제를 말하는데, 비대면 관리와, 개인화된 치료가 가능한 접근방법이다. 이를 통해 경도인지장애 치료를 위한 요소인 훈련 몰입, 다각적 접근, 개인화된 훈련을 효과적으로 전달할 수 있다. 알츠가드는 이러한 요소를 중점으로 에이전트 ‘새미’와의 대화, 5 개 영역의 인지강화 훈련, 건강정보와 소셜 기능을 제공하며 이를 통해 경도인지장애를 치료하고 더 나아가 치매를 예방하고자 한다.

<P>The neural mechanisms underlying the development and maintenance of posttraumatic stress disorder (PTSD) have long been studied. However, little is known about the neural correlates of the recovery process from PTSD. A 5-year longitudinal study was conducted to investigate the trajectory of structural connectivities of the amygdala in disaster survivors with PTSD. Thirty disaster survivors, who were diagnosed with PTSD, and 29 healthy individuals, who were not exposed to trauma, underwent three waves of assessments including neuroimaging scanning over a 5-year period from the time of the disaster at approximately 1.3-year intervals. All disaster survivors showed significant improvements in PTSD symptoms over time. Using diffusion tensor imaging analysis, a 5-year trajectory of amygdalar structural connectivities with key brain regions was assessed. The amygdala insula connection was initially strengthened and then normalized during recovery, while the amygdala prefrontal cortex (PFC) connection was at first unaffected, then strengthened, and eventually normalized. The lower tract strength of the amygdala thalamus connection normalized during recovery, while that of amygdala hippocampus connection remained low. The greater amygdala PFC connectivity was associated with less PTSD symptom severity. The present longitudinal study revealed that recovery from PTSD parallels dynamic and sequential shifts in amygdalar connectivities with multiple brain regions, suggesting the expanded view of fear circuitry including the insula and-thalamus, beyond the traditional model which primarily involves the amygdala, PFC, and hippocampus.</P>
한국 농촌 여성의 스트레스 정도에 따른 항산화 영양소 섭취와 대사증후군 위험도

본 연구는 스트레스 정도에 따른 영양소 섭취와 대사증후군 위험도를 분석하고자 수행되었다. 본 연구는 40~69세 일반인구 집단을 대상으로 실시한 한국인 역학조사 사업 중 농촌기반코호트를 이용하여 진행하였고, 그중 여성을 대상으로 분석하였다. 대상자들은 사회 심리적 건강측정도구(Psy chosocial Well-being Index, PWI)를 기초로 하여 개발된 18문항의 단축형(PWI-SF)의 평균값을 기준으로 0~26점의 저스트레스군과 27점 이상인 고스트레스군으로 분류되었다. 영양 섭취 상태 및 식습관은 반정량식품섭취빈도조사방법(semi-quantitative food frequency questionnaire, SQFFQ)을 이용하여 평가하였다. 고스트레스군 대상자들은 저스트레스군보다 나이, 허리둘레, 혈압이 유의적으로 낮았으며 신장은 유의적으로 높았다. 혈액분석 결과에서는 고스트레스군이 저스트레스군보다 공복혈당, 인슐린 저항성 지수, 중성지방, 동맥경화 지수가 유의적으로 높았다. 영양소섭취를 분석한 결과 고스트레스군 대상자들이 저스트레스군보다 항산화 영양소인 비타민 A, 비타민 C, 비타민 E, 엽산, 아연, 카로틴을 더 적게 섭취하였다. 과일과 채소의 섭취량 또한 고스트레스군이 저스트레스군보다 유의적으로 적었다. 스트레스와 대사증후군 위험의 관계를 살펴본 결과 고스트레스군 대상자들이 저스트레스군보다 대사증후군의 교차비가 유의적으로 높았다. 결과적으로 한국 농촌 여성에서 스트레스가 높을수록 항산화 영양소와 과일 및 채소의 섭취가 적었으며 대사증후군 위험이 증가하는 것으로 나타났다. The aim of the present study was to investigate antioxidant nutrient intake and risk of metabolic syndrome based on stress level in rural Korean women. Subject were participants from the Multi-Rural Communities Cohort Study, which was a part of the Korean Genome and Epidemiology Study. According to scores of the Psychosocial Well-Being Index Short-Form, a total of 10,111 subjects were classified into ‘low stress group (n=8,015)’ from 0 to 26 points and ‘high stress group (n=2,096)’ above 27 points. Data were collected using self-administered questionnaires, anthropometric measurements, and blood chemical analysis. Dietary nutrient consumption was assessed by a semi-quantitative food frequency questionnaire. High stress group showed lower intake of antioxidant nutrients, such as vitamin A, vitamin C, vitamin E, folate, zinc, and carotene compared to the low stress group. Intake of fruits and vegetable was lower in the high stress group compared to the low stress group. Subjects with high stress showed higher risk of hypertension [odd ratio (OR), 95% confidence interval (CI)=1.226 (1.112∼1.351)] and hypertriglyceridemia [OR, 95% CI=1.227 (1.110∼1.356)] than subjects with low stress. High stress group had a significantly greater odds ratio for metabolic syndrome compared with the low stress group [OR, 95% CI=1.216 (1.101∼1.342]). Thus, the present study suggests that high stress might be associated with low intake of antioxidant nutrients and high risk of metabolic syndrome in rural Korean women.
