| dc.description.abstract | Given that humans spend one third of their lives sleeping, maintaining high-sleep quality is essential to life. Recent studies have suggested that dietary factors might improve sleep quality. In particular, seafood and its components, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been known to exert beneficial effects on sleep quality. This study investigated the longitudinal association of seafood consumption with the risk of poor sleep quality in 2,333 adults aged 45–75 years during a 6-year follow-up of the Korean Genome and Epidemiology Study (KoGES). Dietary consumption and composite dietary antioxidant index (CDAI) were assessed using a validated 106-item food frequency questionnaire. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The subject’s inflammatory status was assessed by measuring high-sensitivity C-reactive protein (hs-CRP) levels. The risk of poor sleep quality according to seafood consumption was examined using the Cox’s proportional hazard model. During a 6-year follow-up period, 118 (9.5%) men and 192 (17.6%) women experienced poor sleep quality. Higher seafood consumption was positively associated with intakes of omega-3 fatty acids, EPA, DHA, and antioxidant nutrients. Longitudinally, the cumulative incidence of poor sleep quality was significantly lower in the group with a higher seafood consumption among women (P = 0.0075). Moreover, a higher seafood consumption was associated with a lower risk of poor sleep quality (P = 0.0420). Additionally, seafood consumption was associated with decreasing risk of poor sleep quality among women in a group with high CDAI scores (P = 0.0487) and low hs-CRP levels (P = 0.0461). These findings suggested that seafood consumption might have beneficial effects on improving sleep quality along with foods rich in antioxidants nutrients among Korean adults.;인간이 일생의 3분에 1을 잠을 자는데 보낸다는 점을 고려하면 수면의 질은 생명 유지에 가장 중요한 요소이다. 최근 연구에 따르면 식이 요인이 수면의 질을 개선하고 수면 장애를 예방하는 효과가 있다고 한다. 특히, 수산식품은 오메가-3계 지방산을 비롯한 다양한 영양소가 풍부하게 함유되어 있어 수산식품의 섭취는 수면의 질에 긍정적인 영향을 미칠 것으로 사료된다. 이 연구는 한국인유전체역학조사사업(Korean Genome and Epidemiology Study, KoGES)의 6년 추적 조사 기간 동안 45-75세 성인 2,333명을 대상으로 수산식품 섭취와 좋지 않은 수면의 질 발생 위험 간의 연관성을 조사하였다. 식이 섭취량과 복합식이항산화지수(Composite Dietary Antioxidant Index, CDAI)는 106개 항목으로 구성된 검증된 음식빈도 설문지를 사용하여 평가하였으며, 수면의 질은 피츠버그 수면의 질 지수(Pittsburgh Sleep Quality Index, PSQI)를 사용하여 평가하였다. 대상자의 염증상태는 hs-CRP 수준을 측정하여 평가하였다. 수산식품 섭취량에 따른 좋지 않은 수면의 질 발생 위험은 COX 회귀분석을 사용하여 조사하였다. 6년간 장기추적결과, 남성 118명(9.5%), 여성 192명(17.6%)이 좋지 않은 수면의 질을 겪는 것으로 나타났다. 수산식품 섭취량이 많을수록 오메가-3계 불포화 지방산, 에이코사펜타엔산 (eicosapentaenoic acid, EPA), 도코사헥사엔산 (docosahexae-noic acid, DHA) 및 항산화 영양소 섭취량이 증가하였다. 수산식품 섭취량이 많아질수록 좋지 않은 수면의 질 누적발생률은 유의적으로 낮았다 (P=0.0075). 또한, 수산식품 섭취량이 많아질수록 좋지 않은 수면의 질 발생 위험이 감소한 것으로 나타났다(P=0.0420). 게다가, 복합식이항산화지수가 높은 여성과 hs-CRP 수준이 낮은 여성에게서 수산식품 섭취가 증가할수록 좋지 않은 수면의 질 발생 위험이 감소하였다 (P=0.0487,P=0.0461). 이러한 연구 결과는 수산식품 섭취는 한국 성인의 수면의 질에 유익한 영향을 미칠 수 있으며 항산화 영양소가 풍부한 식품을 함께 섭취한다면 한국 성인의 수면의 질에 유익한 영향을 미칠 수 있음을 시사한다. | - |
