dc.description.abstract사회심리적 스트레스는 잠재적으로 식행동을 조절할 수 있다고 알려져 있을 뿐 아니라 비감염성 질환의 독립적인 위험인자임이 밝혀졌다. 본 연구는 한국인유전체역학조사사업(Korean Genome and Epidemiology Study, KoGES)의 지역사회 기반 코호트 자료를 토대로 2005년부터 2015년까지의 10년 동안의 추적조사를 통해 40-69세의 성인 4,411명을 대상으로 사회심리적 스트레스와 식행동 및 복부비만의 관련성을 분석하였다. 스트레스 수준을 평가하기 위해 사회심리적웰빙지수(Psychosocial Well-being Index Short Form, PWI-SF)를 이용하였으며, 식행동은 식품 다양성 점수(Dietary Variety Score, DVS)를 중심으로 하여 분석하였다. 여성의 경우 스트레스 수준이 높을수록 식품 다양성 점수는 감소하였다. 스트레스 수준이 높을수록 곡물류 및 정제곡물류의 섭취량은 증가하는 반면, 과일류 섭취량은 감소하였다. 또한 여성의 경우 스트레스 수준이 높을수록 에너지 섭취량이 낮았음에도 불구하고 탄수화물의 섭취량은 높았다. 여성의 경우 곡물류 및 정제곡물류의 섭취량이 많을수록 복부비만의 위험비가 유의적으로 높게 나타났다 (HR: 1.36, 95% CI: 1.04–1.78, P = 0.0233; HR: 1.28, 95% CI: 1.03–1.59, P = 0.0247, respectively). 또한 스트레스 수준이 높을수록 복부비만의 위험비가 증가하였다(HR: 1.27, 95% CI: 1.00–1.59, P = 0.0470). 결과적으로 높은 사회심리적 스트레스는 식품 다양성이 낮고, 정제곡물류의 섭취가 높은 식행동을 야기하여, 추적조사 기간 동안 복부비만의 위험성을 높이는 것으로 사료된다.;Psychosocial stress is recognized as a potential modulator of eating behavior. Psychosocial stress also constitutes an independent risk factor for the development of non-communicable diseases. We performed a longitudinal analysis of the relationships among perceived stress, eating behavior, and abdominal obesity in 4,411 adults aged 4069 years during a 10-year follow-up of the Korean Genome and Epidemiology Study (KoGES). Psychosocial stress was evaluated using the Psychosocial Well-being Index Short Form (PWI-SF), and eating behavior was analyzed with a focus on the dietary variety score (DVS). Higher stress levels were associated with higher consumption of grains, especially refined grains, but lower consumption of fruits. Moreover, as stress levels increased, the DVS decreased in women. A low DVS was positively associated with the consumption of grains and refined grains but was negatively associated with the consumption of fruits. In addition, women with higher levels of stress showed higher carbohydrate intake despite a lower total energy intake. Prospectively, a higher consumption of grains and refined grains in women increased the risk of abdominal obesity (HR: 1.36, 95% CI: 1.04–1.78, P = 0.0233; HR: 1.28, 95% CI: 1.03–1.59, P = 0.0247, respectively). By contrast, in all subjects, a higher consumption of fruits decreased the risk of abdominal obesity (men, HR: 0.56, 95% CI: 0.45–0.70, P < .0001; women, HR: 0.51, 95% CI: 0.40–0.65, P < .0001). Furthermore, higher stress levels showed a borderline significant association with the risk of abdominal obesity in women (HR: 1.27, 95% CI: 1.00–1.59, P = 0.0470). These findings suggested that psychosocial stress might contribute to abdominal obesity by interacting with eating behavior represented by a low DVS. The approach to consume a diet with a high DVS might help decrease the risk of abdominal obesity among people in stressful environments.-
