Background: Though a large proportion of cancer survivors are assumed to be commonly affected by sleep disturbance, few studies have focused on short sleep problems and its correlates among Korean cancer survivors. The purpose of this study was to evaluate the prevalence of short sleep in adult cancer survivors from a nationwide population-based sample and to identify risk factors for short sleep duration. Materials and Methods: Based on the fourth and fifth Korea National Health and Nutrition Examination Surveys (2007-2012), 1,045 cancer survivors and 33,929 non-cancer controls were analyzed. The prevalence of short sleep was compared between these two groups. Associations between short sleep and its correlates were evaluated using multiple logistic regression among cancer survivors: odds ratios (ORs) and 95% confidence intervals (95%CIs) were estimated after adjusting for sociodemographic factors, lifestyle factors, psychological conditions, and cancer-related factors. Results: About 8.1% of cancer survivors slept for less than 5 hours per day (6.2% men and 9.3% women), whereas this was the case for only 3.7% of non-cancer controls. Cancer survivors who had the lowest household income level showed a significantly higher likelihood for short sleep (adjusted OR 2.82, 95%CI 1.06-7.54). Self-reported poor health and depressive symptoms were found to be associated with significantly increased likelihood for short sleep in cancer survivors (adjusted OR 3.60, 95%CI 1.40-9.26 and adjusted OR 2.00, 95%CI 1.17-3.42). Gastric cancer survivors had a 3.97-fold increased risk for short sleep (95%CI 1.60-9.90). Conclusions: The prevalence of short sleep occurs at a high rate among the Korean cancer survivors, which may indicate a poorer quality of life and a higher risk of future complications in survivorship. Targeted interventions that can assist cancer survivors to cope with sleep disturbances as well as ensuring psychological stability are warranted to reduce the latent disease burden.

Purpose: This study was to examine the cardiopulmonary symptoms, quality of sleep, and depression, and to identify the influencing factors in the hospitalized coal worker's pneumoconiosis patient. Methods: 137 hospitalized patients who received pneumoconiosis treatment were conveniently selected. A descriptive correlational study was conducted. Data were collected using structured questionnaires and were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression analysis. Results: The mean score of cardiopulmonary symptoms was relatively high ($3.97{\pm}0.56$, out of 5). The 5 and over score of quality of sleep, sleep disturbance was 94.2%, and the reported depression was 95.6%. The levels of depression depended on the oxygen therapy and family/acquaintance visiting. The depression was significantly correlated with the cardiopulmonary symptoms and quality of sleep. The influential factors affecting depression were cardiopulmonary symptoms and quality of sleep, which explained about 34.1% of the variance. Conclusion: The results of this study indicate that nursing interventions are needed to reduce depression, and to improve cardiopulmonary symptoms and quality of sleep in the hospitalized pneumoconiosis patient. These results can provide for nursing intervention to facilitate reduction of depression.

Objective : The aim of this study was to investigate the relationship between subjective sleep problems and various types of traumatic events of patients with depressive disorder. Methods : A total of 411 patients diagnosed with depressive disorders were recruited in this study. The participants filled out Life Time Events Checklist (LEC), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI). We used the independent t-test and analysis of covariance to compare each component of PSQI between depressive patients with and without traumatic experiences. Results : The groups of patients who experienced a serious accident at work, home or during recreational activity, sexual assault, other unwanted or uncomfortable sexual experience, life-threatening illness or injury, and sudden, unexpected death of a near and dear one showed lower scores in a few components of PSQI. Sleep disturbance was a common problem in all five groups. Lower subjective sleep quality and longer sleep latency was observed in three groups. There were no differences in the other components of PSQI among groups. Conclusion : This study showed that various types of traumatic events may have different effects on subjective sleep quality as a consequence of the traumatic event which they had experienced.

Purpose: The purpose of this study was to review previous literature with an aim to explore the sleep disturbance level after a patient undergoes cataract surgery using an integrative review. Methods: We used the key words, 'cataract surgery', 'sleep', and 'intraocular lens' to find peer-reviewed publications in seven databases. Among 450 searched articles, eight articles were selected after exclusion of articles that did not meet the criteria. Results: Five of the articles submitted that subjective sleep quality of the patients with blue-filtering intraocular lens (BF-IOL) implant improved as compared to that before surgery. The change of saliva melatonin concentration after BF-IOL implant did not coincide in two of the articles. Two of the articles reported an increased level of intrinsically photosensitive retinal ganglion cells response after BF-IOL implantation. Conclusion: The published studies stated that BF-IOL implant did not have any negative impact on quality of sleep among cataract patients suffering with poor sleep. Rregardless of intraocular lens type, cataract surgery may increase photoreception of intrinsically photosensitive retinal ganglion cells one year after surgery although the mechanism was not clear. It is necessary to identify various factors influencing the quality of sleep such as gender and activities among cataract patients with BF-IOL implant in the future.

배 경 : 폐쇄성 수면무호흡증은 다양하고 심각한 임상 증상과 합병증을 유발하는 질환으로 국내에서도 흔히 진단되고 있다. 그러나 현재까지 수면다원기록법을 사용해 폐쇄성 수면무호흡증을 확진한 환자들의 대규모 국내 연구를 찾아 볼 수 없었다. 본 연구에서는 종래의 연구에서보다 더 큰 집단을 대상으로 수면다원기록법을 사용해 폐쇄성 수면무호흡증으로 확진된 한국인 환자의 임상적 특성과 수면 양상에 관해 조사하였다. 방 법 : 서울대학교병원 수면다원검사실에 의뢰된 환자들 중 수면다원검사 결과 폐쇄성 수면무호흡증으로 진단된 환자 801명을 대상으로 하였다. 중추성 무호흡증, 주기성 사지운동증, 기면병, 렘수면관련행동장애, 그리고 외국인 환자는 제외하였다. 연구 대상 군의 임상적 특징을 조사하였으며 수면 변인들을 연령, 성별에 따른 정상치와 비교하였다. 그리고 호흡장애지수가 수면변인에 미치는 영향을 분석하였다. 결 과 : 전체 연구대상자 801명 중 남자가 83.4%, 여자가 16.4%이었고 평균 연령은 46.6세였다. 평균 비만정도 지수는 25.8이었고 비만한 환자가 22.8%를 차지하였다. 전체 대상 중 6.2%가 벤조디아제핀계 약물을 복용 중이었다. 연구 대상군에서 정상치에 비해 입면잠복시간은 증가되었고 수면효율, 렘수면 분율, 그리고 서파수면 분율은 감소하였다. 서파수면 분율과 렘수면 분율은 각각 호흡장애지수와 음의 상관성을 보였으나 수면효율과 입면잠복시간은 모두 호흡장애지수와 유의한 상관관계가 없었다. 결 론 : 본 연구에서 다수의 폐쇄성 수면무호흡증 환자가 비만과 무관하였다. 또한 6.2%의 폐쇄성 수면무호흡증 환자가 벤조디아제핀계 약물을 복용하고 있었다. 폐쇄성 수면무호흡증의 발병은 수면효율도 낮추고 서파수면과 렘수면 분율을 감소시키나 호흡장애지수가 커져도 서파수면과 렘수면 분율이 감소할 뿐 수면효율은 별 다른 변화가 없었다. 즉, 수면효율보다는 수면 구조의 변화가 수면 중 호흡장애의 정도에 더 관련되었음을 알 수 있었다.

Purpose: This study was performed to evaluate the effects of non-pharmacological interventions on sleep disturbance amongst adults aged 55 and above. Methods: PubMed, Cochrane Library, EMBASE, CINAHL and several Korean databases were searched. The main search strategy combined terms including non-pharmacological interventions and presence of insomnia. Non-pharmacological interventions included cognitive behavioral therapy, auricular acupuncture, aromatherapy, and emotional freedom techniques. Methodological quality was assessed using Cochrane's Risk of Bias for randomized studies and Risk of Bias Assessment tool for non randomized studies. Data were analyzed by the RevMan 5.3 program of Cochrane Library. Results: Sixteen clinical trials met the inclusion criteria with a total of 962 participants. Non-pharmacological interventions was conducted for a mean of 5.5 weeks, 7.7 sessions, and an average of 70 minutes per session. The effects of non-pharmacological interventions on sleep quality (ES=-1.18), sleep efficiency (ES=-1.14), sleep onset latency (ES=-0.88), awakening time after sleep onset (ES=-0.87), and sleep belief (ES=-0.71) were significant, and their effect sizes were ranged from moderate to large. However, the effects on total sleep time and insomnia severity were not significant. Conclusion: The findings of the current study suggest that non-pharmacological interventions have a positive impact on attitudes and beliefs about sleep, sleep quality, sleep duration, and sleep efficiency. Therefore, the findings of the study provide an evidence to incorporate various non-pharmacological interventions into nursing practice to improve both sleep quality and quantity in patients with insomnia.

Jet lag can be defined as the cumulative physiological and psychological effects of rapid air travel across multiple time zone. The consequences of jet lag include fatigue, general malaise, sleep disturbances, and reductions of cognitive and psychomotor performance, all of which have been documented in experimental biological and air crew personnel studies. Thus authors tried to study the jet lag of natural travellers by modified self reporting sleep log. Total 61 healthy travellers was studied for 3 days before and 7 days after jet-flights across seven to ten time zone. The eastbound travelling group was 38 persons, aged 19 -70 and westbound travelling group was 23 persons, aged 13 - 69. Sleep onset time, wake-up time, sleep latency, awakening frequency on night sleep, awakening duration on night sleep, sleepiness at wake-up and nap length were evaluated. Our results suggested that the 7 to 10 time zone shift gave significant influence to traveller's sleep-wake cycles. The date which subjective physical condition was recovered on was $5.16{\pm}1.50$ day after arrivals for eastbound, while for westbound, $4.91{\pm}1.62$ day. In eastbound travelling, sleep onset time became later than baselines and could not recover until 7th day. But in westbound, it became earlier than baseline and could recover until 6th day. The mean score of 24-hour sleepiness was greater in eastboumd than westbound. Therefore the eastbound travelling caused more sleep-wake cycle disturbance and daytime dysfunction than westbound travelling. In other parameters, there was no definite difference between east and westbound. From our results, it was suggested that the symptom severity of jet lag was dependent on the travelling direction. To demonstrate more definite evidence, large sized data collections and comparision by age difference were needed.

This study aimed to analyze the correlation between working from home and sleep disorders among domestic workers using data from the 5th Working Environment Survey in 2017. Out of the total 30,108 wage workers, 818 employees work from home and 4,090 work in an office. A random sample of 1:5 pairs, considering gender and occupational group, was selected from these employees as the study subjects. The analysis included personal characteristics, occupational characteristics, work-from-home arrangements, and sleep disorders. Age, education, employment status, years in the workforce, weekly working hours, work-life balance, self-perceived health, depression, and anxiety were all adjusted as potential confounding variables. Conditional logistic regression analysis was conducted to examine the relationship between working from home (independent variable) and sleep disorder (dependent variable). This analysis aimed to analyze the correlation between working from home and sleep disorder. The analysis revealed that working from home was associated with sleep onset latency disorder OR=3.23 (95% CI=2.67~3.91), sleep maintenance disorder OR=3.67 (95% CI=3.02~4.45), and non-restorative sleep OR=3.01 (95% CI=2.46~3.67), which showed a statistically significant relationship with all three types of sleep disorders. Factors influencing the correlation between working from home and sleep disorders included work-life balance, social isolation, and anxiety.
