This study was undertaken to investigate whether the stress caused by day/night shifts on industrial workers can be affected through nutritional status. A sample of 573 female industrial workers, aged 17 through 23 years, from 4 different industries (2 in normal, 2 in 3 shift work pattern) were surveyed by questionaire examining their nutritional status, food intake, dietary habit, sleep complaint, performance of digestive organs, and degree of fatigue. Shift workers were surveyed during night work. The results are summarized as follows: 1. Sleep complaints and degree of fatigue in shift workers were higher than normal workers, whereas the performance of digestive organs were as lower than normal workers. These results showed that shift workers were more stressed than normal workers. 2. The workers who were surveyed were all poor in nutritional status. The intakes of calorie, protein, Ca, riboflavin, and ascorbic acid were lower than Korean Recommanded Dietary Allowences (RDA). Dietary habit of the shift workers was irregular. 3. There was a negative correlation between nutritional status and degrss of fatigue. The intakes of energy nutrients, ascorbic acid, and niain were significantly related to the degree of fatigue in which protein intake was found to be most influential. Among workers with the same level of protein intake, shift workers showed higher degree of fatigue. When the protein intake of shift workers was 100-125% of R.D.A., they showed the same degree of fatigue to the average normal workers.

Background: This study aimed to identify the validity of breast cancer symptom questionnaire of worker's special health examination and its relationship with breast ultrasonography findings in young female night workers. Methods: The breast cancer symptom questionnaire data of worker's special health examination and breast ultrasonography results in young female shift workers who worked in one electronic manufacture company were collected from 2014 to 2018. Results: Of the 857 workers, 18 had a Breast Imaging Reporting and Database System category 4 or higher. Among other variables, shift work tenure alone was associated with the risk of having a Breast Imaging Reporting and Database System category higher than 4. The sensitivity, specificity, positive predictive value, and negative predictive value of the symptom questionnaire were 16.7%, 87.7%, 2.8%, and 98.0%, respectively. Conclusion: The current breast cancer symptom questionnaire of the worker's special health examination is inappropriate due to its low sensitivity and positive predictive value. In the future, female night workers will need alternative measures for more accurate screening for breast cancer.

Genotype of ALAD and VDR yields two alleles, respectively and it has been implicated in susceptibility to lead toxicity. Also genotype known to variety by race. To evaluate the genetic susceptibility of ALAD and VDR gene on health effect of lead exposure, this study was done with new workers who entered lead industries from 1992 to 2001. Among database of lead industries of Soonchunhyang University Institute of Industrial Medicine, only new workers were selected for this study. The total of eligible workers for this category was 3,540 workers including non lead exposed workers of same lead industries. Genotype of ALAD and VDR were measured from stored blood in specimen bank of Soonchunhyang University, blood lead and other relevant information were obtained from database of each workers which were gathered at their first year of employment. Among 3,540 new employed study subjects during period of 1992-2001, 3204 workers(90.5%) had ALAD genotype 1-1; whereas 336 workers(9.5%) had variant type of ALAD (1-2 or 2-2). Lead exposed workers, 9.8%(n=243) male and 8.1%(n=16) female were heterozygous for the ALAD allele. Also non lead exposed workers, 8.9%(n=67) male and 9.3%(n=10) female were heterozygous for the ALAD allele. For VDR genotype, 2,903 workers(89.7%) out of total tested 3,238 workers were belonged to type bb and 335 workers(10.3%) were type bB or BB. Lead exposed workers, 10.4%(n=235) male and 12.2%(n=24) female were heterozygous for the VDR allele. Also non lead exposed workers, 9.2%(n=64) male and 12.5%(n=12) female were heterozygous for the VDR allele. No significant differences were seen in mean blood lead levels by ALAD and VDR genotype, nor was significantly associated with blood lead except age in multiple regression analysis.
