연구목적 역학연구 우울척도 개정판은 우울 증상을 평가하는 데에 유용성이 입증된 척도로 알려져 있으며 '정신장애의 진단 및 통계 편람 제4판(DSM-IV)'에 기술되어 있는 주요우울장애의 주요한 우울 증상들을 포괄하고 있다. 이 연구에서는 한국판 역학연구 우울척도 개정판을 제작하여 척도의 신뢰도, 타당도와 특성을 평가하고자 하였다. 방 법 DSM-IV의 진단기준에 근거한 MINI를 사용하여 주요우울증, 기분부전증, 달리 분류되지 않는 우울장애로 진단된 48명의 환자군과 48명의 정상 대조군이 연구에 참여하였다. 연구 참여자들은 한국판 역학연구 우울척도 개정판, 몽고메리-아스버그 우울증 평가척도, 우울증 선별척도, 단축형 우울증상 평가 척도, 상태-특성 불안척도를 포함한 척도검사를 시행하여 교차 검증하였다. Cronbach's alpha 계수, Pearson 상관계수, 주성분 분석, Receiver Operating Characteristic(ROC) 곡선, 최적 절단점 산출을 위한 통계분석을 시행하였다. 결 과 한국판 역학연구 우울척도의 Cronbach's alpha 계수는 0.98이었으며, 한국판 역학연구 우울척도 개정판의 총점은 본 연구에서 시행하였던 다른 우울 및 불안척도의 점수와 높은 상관 관계를 보였다. 주성분 분석에서는 두 요인이 전체 분산의 76.29%를 설명하였으며, ROC 곡선을 이용하였을 때, 한국판 역학연구 우울척도 개정판의 최적 절단점은 13점이었다. 결 론 본 연구는 한국판 역학연구 우울척도 개정판의 표준화를 위한 첫 번째 연구로, 한국판 역학연구 우울척도는 우울 증상을 평가하는데 있어 신뢰성 있고, 타당한 척도임을 밝혔다. 또한 이 척도가 진료 및 역학 연구에서 유용한 선별검사 도구로 사용될 수 있을 것으로 기대한다.

Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.

Objectives : Genome-wide association studies (GWASs) and meta-analyses indicate that single-nucleotide polymorphisms (SNPs) in the a-1C subunit of the L-type voltage-dependent calcium channel (CACNA1C) gene increase the risk for schizophrenia and bipolar disorders (BDs). We investigated the association between the genetic variants on CACNA1C and schizophrenia and/or BDs in the Korean population. Methods : A total of 582 patients with schizophrenia, 336 patients with BDs consisting of 179 bipolar I disorder (BD-I) and 157 bipolar II disorder (BD-II), and 502 healthy controls were recruited. Based on previous results from other populations, three SNPs (rs10848635, rs1006737, and rs4765905) were selected and genotype-wise association was evaluated using logistic regression analysis under additive, dominant and recessive genetic models. Results : rs10848635 showed a significant association with schizophrenia (p=0.010), the combined schizophrenia and BD group (p=0.018), and the combined schizophrenia and BD-I group (p=0.011). The best fit model was dominant model for all of these phenotypes. The association remained significant after correction for multiple testing in schizophrenia and the combined schizophrenia and BD-I group. Conclusion : We identified a possible role of CACNA1C in the common susceptibility of schizophrenia and BD-I. However no association trend was observed for BD-II. Further efforts are needed to identify a specific phenotype associated with this gene crossing the current diagnostic categories.
