초록

연구목적 이전 연구에 따르면 교대근무는 인간의 자연적인 일주기 리듬에 적응하기 어렵게 만들어 각종 건강문제를 일으킨다. 특히 교대근무자는 근무 일정과 연관된 수면의 어려움을 호소하는 경향이 있으며, 알코올을 수면유도를 위한 자가약으로 사용하는 경우가 있다. 현재까지 교대근무와 수면 및 음주와의 관련성에 관한 명확한 기전이 밝혀지지 않고 있는 상태이다. 따라서 이 연구에서는 교대근무와 수면과의 관련성을 확인하고, 교대근무로 인한 수면의 변화가 음주를 유발하는지에 대해 분석하고자 한다. 방 법 이 연구는 국민건강영양조사 제6기, 제7기 자료 중 2014, 2016, 2018년도를 분석대상으로 하였으며 총 11360명(남성 5704명, 여성 5656명)을 연구대상인원으로 포함시켰다. 6 am-6 pm사이의 근무형태를 주간근무, 이외의 근무형태를 교대근무로 정의하였으며 로지스틱 회귀분석을 통하여 교대근무와 수면의 질, 교대근무와 고위험 음주, 음주량 및 음주 횟수의 관계를 분석하였다. 또한 매개분석을 통하여 수면이 교대근무와 음주의 관계를 매개하는지 여부를 분석하였다. 결 과 교대근무는 남성과 여성에서 수면 질과 유의한 음의 관계를 보였다(남성 OR=1.37, 95% CI=1.11-1.70, 여성 OR=1.26, 95% CI=1.05-1.50). 교대근무와 음주와의 관계에서는 남성의 경우 유의한 관계가 나타나지 않았으나, 여성의 경우 교대근무와 음주횟수에서 유의한 양의 관계를 보였다(OR=1.34, 95% CI=1.04-1.72). 매개분석 시행 시 여성의 수면 질은 교대근무와 음주횟수의 관계를 부분매개하는 것으로 나타났다. 결 론 이 연구의 결과는 교대근무가 수면의 어려움을 유발하며, 여성의 경우에서는 수면의 부분매개효과를 통해 음주를 유발할 수 있음을 시사한다. 여성이 수면장애에 대한 대처방안으로 음주를 선택할 가능성이 높은 점을 고려할 때, 여성 교대근무자에 대한 보다 적극적인 중재방안이 마련된 필요가 있다.

Objectives : Shift work has been known to cause various health problems by making it difficult for humans to adapt to their natural circadian rhythms. In particular, shift workers tend to complain of sleep difficulties associated with work schedules, and sometimes use alcohol as a self-medication to induce sleep. To date, no clear mechanism has been identified regarding the link between shift work and sleep, between shift work and drinking. This study aims to confirm the relationship between shift work and sleep, and to analyze whether the change in sleep caused by shift work causes drinking. Methods : This study included 11360 people (5704 men and 5656 women) among the Korean National Health and Nutrition Survey data in 2014, 2016 and 2018. The work type between 6am-6pm was defined as day work, and other work types were defined as shift work. Using logistic regression analysis, the relationship between shift work and sleep quality, shift work and high risk drinking, drinking amount at 1 time, drinking frequency were analyzed. In addition, we analyzed whether sleep mediates the relationship between shift work and drinking using mediated analysis. Results : Shift work showed a significant negative relationship with sleep quality in men and women (male OR=1.37, 95% CI 1.11-1.70, female OR=1.26, 95% CI=1.05-1.50). There was no significant relationship between shift work and alcohol in the case of men, but in the case of women, there was a significant positive relationship between shift work and the number of alcohol consumption (OR=1.34, 95% CI=1.04-1.72). When mediation analysis was conducted, it was found that women's sleep quality partially mediated the relationship between shift work and the frequency of drinking. Conclusions : The results of this study suggest that shift work causes sleep difficulties, and in the case of women, drinking can be induced through the partial mediating effect of sleep. Considering that women are more likely to choose drinking as a coping method for sleep problems, more active interventions for female shift workers are needed.
