The relationship between quality of sleep and night shift rotation interval

BACKGROUND: Shift work is closely related with workers' health. In particular, sleep is thought to be affected by shift work. In addition, shift work has been reported to be associated with the type or direction of shift rotation, number of consecutive night shifts, and number of off-duty days. We aimed to analyze the association between the night shift rotation interval and the quality of sleep reported by Korean female shift workers. METHODS: In total, 2,818 female shift workers from the manufacturing industry who received an employee physical examination at a single university hospital from January to August in 2014 were included. Subjects were classified into three groups (A, B, and C) by their night shift rotation interval. The quality of sleep was measured using the Korean version of the Pittsburgh Sleep Quality Index (PSQI). Descriptive analysis, univariate logistic regression, and multivariate logistic regression were performed. RESULTS: With group A as the reference, the odds ratio (OR) for having a seriously low quality of sleep was 1.456 (95% CI 1.171-1.811) and 2.348 (95% CI 1.852-2.977) for groups B and C, respectively. Thus, group C with the shortest night shift rotation interval was most likely to have a low quality of sleep. After adjustment for age, obesity, smoking status, alcohol consumption, exercise, being allowed to sleep during night shifts, work experience, and shift work experience, groups B and C had ORs of 1.419 (95% CI 1.134-1.777) and 2.238 (95% CI 1.737-2.882), respectively, compared to group A. CONCLUSION: Our data suggest that a shorter night shift rotation interval does not provide enough recovery time to adjust the circadian rhythm, resulting in a low quality of sleep. Because shift work is influenced by many different factors, future studies should aim to determine the most optimal shift work model and collect accurate, prospective data.

Anxiety symptoms and occupational stress among young Korean female manufacturing workers

BACKGROUND: The prevalence of anxiety disorders has been increasing in South Korea, with recent studies reporting anxiety disorders as the most common mental disorder among all South Korean females. Anxiety disorders, which are independent risk factors of suicidal ideation and suicide attempts, are significantly correlated with productivity loss, high medical costs, impaired work performance, and frequent worker absence, and thus are potentially serious problems affecting the health of South Korean female workers. In previous studies, anxiety disorders were shown to have a significant correlation with occupational stress. This study seeks to examine the prevalence of anxiety symptoms as well as the relationship between occupational stress and anxiety symptoms among South Korean female manufacturing workers. METHODS: A structured self-reported questionnaire was administered to 1,141 female workers at an electrical appliance manufacturing plant. The questionnaire collected data on general characteristics, health behaviors, sleep quality, job characteristics (shift work, shift work schedule, and job tenure), occupational stress, and anxiety symptoms. Sleep quality was measured using the Pittsburgh Sleep Quality Index, occupational stress with the Korean Occupational Stress Scale-Short Form (KOSS-SF), and anxiety symptoms with the Korean version of the Beck Anxiety Inventory. A chi square test was conducted to determine the distribution differences in anxiety symptoms based on general characteristics, health behaviors, job characteristics, and sleep quality. A linear-by-linear association test was used to determine the distribution differences between anxietysymptoms and the levels of occupational stress. Last, logistic regression analysis was used in order to determine the association between occupational stress and anxiety symptoms. RESULTS: The prevalence of anxiety symptoms was 15.2 %. In the multivariate logistic regression analysis that adjusted for sleep quality and general characteristics, a significantassociation was found for those with anxiety disorders; the odds ratios (OR) were significantly higher the greater the total KOSS-SF score (moderate-risk group OR=2.85, 95 % CI=1.79-4.56; high-risk group OR=5.34, 95 % CI=3.59-7.96). In addition, excluding insufficient job control, all other KOSS-SF subscales were significantly associated with anxiety symptoms, and a relatively high OR was seen in the high-risk group for job demand (OR=3.19, 95 % CI=2.27-4.49), job insecurity (OR=4.52, 95 % CI=2.86-7.13), and occupational culture (OR=4.52, 95 % CI=2.90-7.04). CONCLUSION: There was a significant association between anxiety symptoms and occupational stress stemming from the psychosocial work environment among these South Korean female manufacturing workers. Future longitudinal studies are needed to examine the association between the occupational stress caused by the psychosocial work environment and the incidence of anxiety disorders and anxiety symptoms. Furthermore, intervention programs that aim to address the prevalence of anxiety symptoms and improve the psychosocial work environment, especially for younger female manufacturing workers, are needed.

Association between serum vitamin D and depressive symptoms among female workers in the manufacturing industry

BACKGROUND: Vitamin D has been known to maintain the body's balance of calcium and phosphorus as well as skeletal health. There has been increasing emphasis on the importance of vitamin D as recent studies have been reporting the specific functions of vitamin D in the cerebral nervous system and the association between the level of serum vitamin D and depressive symptoms. However, there is currently a paucity of research investigating the association between serum vitamin D and depressive symptoms in Korean subjects. Consequently, this study has aimed to determine the level of serum vitamin D and explore the association between serum vitamin D and depressive symptoms in Korean female workers. METHOD: A medical examination, questionnaire, anthropometric measurements, and a blood test were conducted between February 3 and March 7, 2014 in 1054 subjects among female workers in the manufacturing industry who underwent physical examinations in a university hospital. From this data, we identified the level of serum vitamin D and investigated the association between serum vitamin D deficiency and depressive symptoms. RESULTS: The average serum vitamin D level of the 1054 subjects was 9.07 +/- 3.25 ng/mL, and the number of subjects in the serum vitamin D deficiency group with less than 10 ng/mL was 721 (68.4 %). The odds ratio of the depressive symptom group with a CES-D score of 16 or above being in the deficiency group with a serum vitamin D level less than 10 ng/mL was found to be 1.55 (95 % CI = 1.15-2.07). CONCLUSION: 68.4 % of female workers in the manufacturing industry were in the deficiency group with serum vitamin D levels less than 10 ng/mL. Additionally, we identified an association between serum vitamin D deficiency and depressive symptoms. In the future, if serum vitamin D deficiency is checked regularly in workers, we expect to achieve better outcomes in managing their depressive symptoms.

The Relationship between Coronary Risk Factors and Coronary Calcium Score Detected by Computed Tomography Coronary Angiography in Korean Middle Aged Men / 農村醫學 地域保健

OBJECTIVES: The objective of this study was to investigate the relationship between coronary artery calcification and risk factors of cardiovascular disease with multidetector computed tomography. METHODS: Data were collected from 5,899 males between 30 and 59 years old by interview, survey, physical examination, blood test, and multidetector computed tomography in the university hospital from January 2010 to December 2011. We confirmed the coronary artery calcium scores of subjects by multidetector computed tomography and identified risk factors of cardiovascular disorders. We investigated the relationship between coronary artery calcification and risk factors of cardiovascular disorders. RESULTS: Mean calcium score of the coronary arteries in 5,899 participants was 8.20, and 773 participants (13.1%) exhibited coronary artery calcification. The presence of coronary artery calcification was correlated to risk factors of cardiovascular disease (age, blood pressure, triglyceride, HDL cholesterol, LDL cholesterol, glucose, Apolipoprotein A-1, Apolipoprotein B, body mass index, waist circumference) and risk assessment tools of cardiovascular disorders. Significant predicted factors of coronary artery calcification had different patterns in each age group (30-39, 40-49, 50-59 years old). CONCLUSIONS: We confirmed the relationship between coronary artery calcification and either typical risk factors of cardiovascular disease or risk assessment tools of cardiovascular disease. In addition, we also observed that the pattern of these factors varied according to age. Therefore, age-related variation needs to be considered in management strategies to prevent cardiovascular disease.

High-resolution Manometry and Globus: Comparison of Globus, Gastroesophageal Reflux Disease and Normal Controls Using High-resolution Manometry

BACKGROUND/AIMS: Globus is a foreign body sense in the throat without dysphagia, odynophagia, esophageal motility disorders, or gastroesophageal reflux. The etiology is unclear. Previous studies suggested that increased upper esophageal sphincter pressure, gastroesophageal reflux and hypertonicity of esophageal body were possible etiologies. This study was to quantify the upper esophageal sphincter (UES) pressure, contractile front velocity (CFV), proximal contractile integral (PCI), distal contractile integral (DCI) and transition zone (TZ) in patient with globus gastroesophageal reflux disease (GERD) without globus, and normal controls to suggest the correlation of specific high-resolution manometry (HRM) findings and globus. METHODS: Fifty-seven globus patients, 24 GERD patients and 7 normal controls were studied with HRM since 2009. We reviewed the reports, and selected 5 swallowing plots suitable for analysis in each report, analyzed each individual plot with ManoView. The 5 parameters from each plot in 57 globus patients were compared with that of 24 GERD patients and 7 normal controls. RESULTS: There was no significant difference in the UES pressure, CFV, PCI and DCI. TZ (using 30 mmHg isobaric contour) in globus showed significant difference compared with normal controls and GERD patients. The median values of TZ were 4.26 cm (interquartile range [IQR], 2.30-5.85) in globus patients, 5.91 cm (IQR, 3.97-7.62) in GERD patients and 2.26 cm (IQR, 1.22-2.92) in normal controls (P = 0.001). CONCLUSIONS: HRM analysis suggested that UES pressure, CFV, PCI and DCI were not associated with globus. Instead increased length of TZ may be correlated with globus. Further study comparing HRM results in globus patients within larger population needs to confirm their correlation.

Abuse potential of propofol used for sedation in gastric endoscopy and its correlation with subject characteristics / 대한마취과학회지

BACKGROUND: Propofol has been widely used for an induction and/or maintenance of general anesthesia, or for sedation for various procedures. Although it has many ideal aspects, there have been several cases of drug abuse and addiction. The authors investigated whether there are abuse liable groups among the general population. METHODS: We surveyed 169 patients after gastric endoscopic examination, which used propofol as a sedative, with the Addiction Research Center Inventory (ARCI) questionnaire. Other characteristics of the patients, such as past history, smoking habits, depression, anxiety, alcohol abuse liability and sleep disturbance, were recorded by history taking and several questionnaires before the exam. RESULTS: Propofol had a high Morphine-Benzedrine Group (MBG) score (representative value for euphoria) of 6.3, which is higher than marijuana, and a Pentobarbital-Chlorpromazine-Alcohol Group (PCAG) score (representative value of sedation) of 8.1, which is lower than most opioids. The MBG score showed no statistically significant correlation between any of the characteristics of the groups. In females, the PCAG score showed a correlation with age, and in males, it showed a correlation with a sleeping problem. CONCLUSIONS: Propofol had relatively high euphoria and low residual sedative effects. It had a more potent sedative effect in the female group who were young, and in the male group who had a low sleep quality index. There were differences in the abuse liability from a single exposure to propofol in the general population. Further study is needed to evaluate the abuse liability of repeated exposure.

Colorimetric comparison of single layered dental composite with double layered dental composite

OBJECTIVES: This study analyzed the difference in color caused by different thickness in enamel layer of composite resins when applied with single and layering placement technique, and evaluated if the results agreed with the shade guide from the manufacturers to verify reliability of the color matching process of the manufacturers. MATERIALS AND METHODS: For single composite resin samples, 6 mm diameter and 4 mm thickness cylindrical samples were fabricated using Ceram-X mono (DENTSPLY DeTrey) and CIE L*a*b* values were measured with spectrophotometer. Same process was done for layering composite resin samples, making 3 dentinal shade samples, 4 mm thickness, for each shade using Ceram-X duo (DENTSPLY DeTrey) and enamel shade resins were layered in 2 mm thickness and CIE L*a*b* values were measured. These samples were ground to 0.2 mm thickness each time, and CIE L*a*b* values were measured to 1 mm thickness of enamel shade resin. RESULTS: Color difference (DeltaE*) between single and layering composite resin was 1.37 minimum and 10.53 maximum when layering thicknesses were between 1 mm and 2 mm and 6 out of 10 same shade groups suggested by manufacturer showed remarkable color difference at any thickness (DeltaE* > 3.3). CONCLUSION: When using Ceram-X mono and duo for composite resin restoration, following the manufacturer's instructions for choosing the shade is not appropriate, and more accurate information for Ceram-X duo is needed on the variation and expression of the shades depending on the thickness of the enamel.

The Relationship of Serum Vitamin D Levels and the Framingham Risk Score among Male Workers in the Manufacturing Sector / 대한산업의학회지

OBJECTIVES: A growing body of evidence states that vitamin D deficiencies may adversely affect cardiovascular disease, however data from Korean workers are lacking. The purpose of this study was to investigate the vitamin D level of the Korean worker and the relationship between vitamin D levels and the Framingham Risk Score. METHODS: 11,448 male workers who visited a university hospital for health screening between March 2010 and August 2011, were enrolled in the study. We measured their of serum vitamin D(25(OH)D) levels and calculated their Framingham Risk Score. RESULTS: The mean serum vitamin D(25(OH)D) level of the surveyed workers was 13.03+/-6.47 ng/mL. 12.4% of the total workers had adequate vitamin D levels. It was found that the lower the vitamin D level, the higher the risk of cardiovascular disease. The Framingham Risk Score and vitamin D levels were found to be significantly related (OR=1.39, 95% CI 1.14~1.68) through a multivariate logistic regression analysis. CONCLUSIONS: 87.6% of workers possessed inappropriate vitamin D levels. Management for this high risk group in regards to cardiovascular disease should be included in the evaluation and vitamin D levels should be corrected.

Plasma Paraquat Concentration and Early Prognostic Factors in Paraquat Poisoning / 대한신장학회지

PURPOSE: Paraquat is a lethal herbicide and induces acute renal failure, hepatic dysfunction, and progressive respiratory failure. The aims of this study are to investigate the correlation between plasma paraquat concentrations and initial laboratory data at Emergency Medical Center and to investigate whether initial laboratory data is useful for predicting outcomes of paraquat-poisoned patients. METHODS: A retrospective analysis by chart review was done on 83 patients who ingested paraquat and who had presented to Emergency center of within 24 hours. Plasma paraquat concentrations, urine dithionite test and initial laboratory parameters including white blood cell count, urine pH, and AST, ALT, BUN, Creatinine, Amylase, Glucose, pH, PaCO2, PaO2, HCO3. Base Excess, Na, K, Cl were obtained at the time of Emergency Center visit. We compared urine dithionite test, plasma paraquat concentrations and Severity Index of Paraquat Pisoning (SSPI) of the survival group to those of the dead group. The patients were divided into four subgroups based on the level of plasma paraquat concentration, their initial laboratory data was compared and analyzed. RESULTS: The mean plasma paraquat concentration in the mortality group was higher than that in the survival group (88.44+/-81.56 vs. 1.32+/-1.72 microgram/mL). Among the initial laboratory data of four subgroups, WBC, Glucose, Cr, pH, HCO3, Bass excess were significantly different between the group of low level of plasma paraquat concentration and higher group. ANCOVA analysis revealed that WBC, HCO3, Bass excess correlated with the level of plasma paraquat concentration significantly. CONCLUSION: The plasma paraquat concentration and SIPP were higher in the mortality group significantly. Initial laboratory data including WBC, Glucose, Cr, pH, HCO3, Bass excess were proven to be significant prognostic factors. Especially WBC, HCO3, Bass excess can be used to predict the outcome of paraquat poisoning.

Prevalence of Spondylolysis in Pre-employment Screening Examination

OBJECTIVE: In Korea, there appears to be an increase in the diagnosis of lumbar spine disorders recently. This trend has urged employers to screen new employees for this disorder. One of the methods for the investigation is the radiological examination of the lumbar spine. We studied the prevalence of spondylolysis according to age and sex with lumbar X-ray (anterior-posterior view and lateral view) of new employees in pre-employment screening examination. We also estimated the outbreak period of spondylolysis by analysing the prevalence rates at each age group, which were the results of our study. METHODS: We gathered the data of lumbar X-ray findings for new employees, who had recieved pre-employment screening examinations in the department of occupational and environmental medicine of Masan Samsung Hospital Korea during a period from January 1, 2002 to December 31, 2005. We analyzed the data to obtain the age and sex prevalence of spondylolysis and spina bifida. RESULTS: The prevalence of spondylolysis for the pre-employment screening examination was 5.9% (male 6.6%; female 4.3%) in this study. The prevalence of spondylolysis after adjusting age and sex was 9.0%. The prevalence of spondylolysis was positively correlated with age, and showed to be higher in female than male. Body mass index of spondylolytic subjects was higher than that of normal. The prevalence of spondylolysis was significantly higher in those with spina bifida than normal subjects. CONCLUSION: The prevalence of spondylolysis of the pre-employment screening examination was 5.9% in this study. The factors which relates with spondylolysis were age, BMI and the prevalence of spina bifida.

Association between Job Stress and Alexithymic Traits / 대한산업의학회지

OBJECTIVES: We evaluated the association between job stress and alexithymic traits in Korean workers. METHODS: Workers (n=521) who visited two university hospitals for medical check-ups were recruited for this study. Job stress was evaluated using the Korean version of Karasek's Job Content Questionnaire (JCQ), and alexithymic traits were assessed using the Korean version of the Toronto Alexithymia Scale (TAS-20K). Crude and adjusted odds ratios (ORs) of job stress scales (job strain, job insecurity, and job dissatisfaction) with alexithymic traits(total TAS score > or =52) were calculated. RESULTS: High job strain compared with low strain had a high, but insignificant association with alexithymic traits (adjusted OR, 2.26; 95% CI, 0.93-5.44). High job insecurity (adjusted OR, 2.26; 95% CI, 1.21-4.22), and high job dissatisfaction (adjusted OR, 1.99; 95% CI, 1.06-3.74) had significant associations with alexithymic traits. CONCLUSIONS: This study suggests that job stress is associated with alexithymic traits in workers.

A Case of Trichloroethylene Intoxication with Neuropsychiatric Symptoms / 대한산업의학회지

BACKGROUND: Trichloroethylene (TCE) has been widely used as a typewriter correction fluid, paint remover, adhesive, spot removers and, particularly, as a degreasing agent in metal-fabricating operation. However, few studies have reported on the effects of TCE intoxication, in spite of numerous occupational accidents arising from TCE intoxication, even until quite recently used in small companies. TCE affects mainly the central nervous system (CNS) and is carcinogenic, even when carefully used and managed. CASE REPORT: A 48-year-old male worker visited our hospital complaining of decreased motivation and general weakness. In history taking, the patient had suffered insomnia, memory disturbance, stuttering, loss of interest and sexual desire, depressive mood for 4 years, dysesthesia with tingling sensation and pain in both extremities, and a nauseas feeling similar to a hangover which had been aggravated for 4 months before admission. The patient had been engaged in metal degreasing with TCE for 8 years. Electromyography indicated disturbance of autonomic function, but there was neither peripheral neuropathy nor cervical radiculopathy. Organic abnormalities including cerebellar atrophy and CNS infection were ruled out, while there was no indication of malignancy in magnetic resonance imaging (MRI) and metabolic disorders and electrolyte imbalances in laboratory test. The authors performed biological monitoring for the possible exposed chemicals. Urinary 2,5-hexanedione, a metabolite of n-hexane, was undetected but 3,331.1 mg/g creatinine of urinary trichloro-compounds, a metabolite of TCE, was detected. The patient was diagnosed as TCE intoxication due to a level of urinary trichloro-compounds in excess of the normal range (300 mg/g creatinine), in addition to an occupational history and clinical symptoms. TCE exposure was stopped in admission and the neuropsychiatric symptoms of the patient were improved as the urinary trichloro-compounds were decreased from 3,331.1 mg/g creatinine to 64.6 mg/g creatinine in 5 days. CONCLUSION: Low-dose, chronic TCE intoxication shows neuropsychiatric symptoms, which are often misrecognized merely as a psychiatric disorder; its appropriate diagnosis, early treatment and exposure assessment are therefore difficult. The neuropsychiatric symptoms in workers who have been exposed to TCE should be monitored, detailed job history should be taken and biological monitoring should be conducted to gain early insight of chronic TCE exposure.

Characteristics of Eating Behaviors of the Long-lived Elderly People in Kyungpook Sung-Ju / 대한지역사회영양학회지

The purpose of this study was to find out the common characteristics of eating behaviors of the long-lived elderly in order to offer the basic data for establishing dietary guidelines for a long and healthy life for the general population. The subjects were three-hundred elderly people over age 85 living in Kyungpook Sung-ju who have no problems in daily living. The general characteristics, nutrition knowledge and attitudes, meal patterns, and food preferences of the subjects were surveyed by individual intervies. The levels of the nutrition knowledge of the subjects were very low(average score ; 4.3) and the correlation coefficient between their nutrition knowledge and attitude score was also low(r=0.323, p=0.000). Most of the subjects(93%) had a regular meal pattern consuming three meals a day. The major staple food was rice mixed with other grains(75%) and the number of side dishes was mostly under four(99%). A majority(73%) had no habit of overeating and 51% of the subjects were taking snacks besides regular meals. Thirty one percent of the subjects had drinking habits and 80% of the drinking subjects had over 40 years of drinking history. The most common frequencies for intakes of various food groups were ; more than once a day(95%) for vegetables ; 2~3 times a week(74%) for green and orange color vegetables ; 2~3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2~3 times a week(49%) for milk ; 2~3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2-3 times a week(49%) for milk ; 2-3 times a week(85%) for seaweeds and 2-3 times a week(81%) for foods cooked with oil. The most preferred foods by the subjects were white rice(staple foods), soybean paste soup(soups), beef and eggs(meats and eggs), yellow croaker and hair tail(fish and shellfish), yoghurt(milk and milk products), all vegetables except carrot(vegetables), and watermelon(fruits). The popular food preparation methods included mixing with seasonings and the most preferred taste was sweet. The results showed that the eating pattern of long-lived elderly was characterized by regularity, simplicity, and no overeating.

Physical Characteristics and Instrumental Activities of Daily Living of the Elderly(85+) in Kyungpook Sung-Ju Area / 대한지역사회영양학회지

The purpose of this study was to investigate the physical characteristics and instrumental activities of daily living(IADL) of the elderly (85+). The subjects were three-hundred elderly people over the age of 85, living in Kyungpook Sung-Ju area who have no problems in daily living. The survey on anthropometric measures and IADL were carried out by individual measurement and interviews using measuring devices and questionnaires. The subject group of the study was composed of 27% males and 73% females, the average age being 87 years old. Notable physical features of the subjects include considerably short statues and small physiques compared to the average Korean elder. The mean Body Mass Index(BMI) was 20.9. The average percentage of body fat in male and female was 21.7% and 29.5% respectively, and the average waist/hip ratio(WHR) was 0.9 and 0.85 respectively. The percentage of the subjects who were able to perform all the IADL was 51% in males and 25% in females. The male subjects were more capable than the females in all the IADL except for preparing meals. BMI showed positive correlations withy weight(r=699), WHR(r=0.157), body fat percentage(r=0.57), lean body mass(r=0368) and total body water(r=0.368). WHR also had positive correlation with weight(r=0.184), BMI(r=0.157), lean body mass(r=0.149) and total body water (r=0.148). Body fat percentage had a positive correlation with weight(r=0.147) and BMI(r=0.265) and total body water(r=0.265). In summary, the elderly(85+) in the Sung-Ju area had considerably smaller physiques than the average Korean elderly and showed a normal range of BMI in average. The IADL of the elderly(85+) appeared to have a positive correlation with lean body mass and total body water and a negative correlation with body fat percentage.
