Relation between sleeping time and obesity along the shift work of adult workers

While workers in various social areas are doing shift works, workers who don’t adjust to them are suffering from destruction of body and life rhythms and having safety accidents and health problems arisen from physical and mental difficulties. Studies on wrong eating habits and sleep disorders handled various job shift and heath problems focusing on sleeping problems related with stress, quality of life and disease and there are several studies on correlations with obesity increase. So, this study intended to find several factors affecting obesity for adult workers and if there is any correlation between sleeping time and obesity. This study took 2,088 objects with regular jobs (656 persons with shift works and 1,432 persons with normal works) in the order of sleeping time, height, and weight excluding 31 persons’ result measured values for 2,119 regular workers out of more than 19 year old 25,122 persons from 22,809 persons of total study objects at the first year (2010) health investigation of 4th and 5th National Health/Nutrition Survey. In order to classify the work pattern into the shift work and normal work and find out the relation between obesity and demographic factor (gender, age and marriage) that is the confounding factor, social & economical factor (income level & educational level) and health pattern factor (smoking, drinking, sleeping time, walking practice, stress, frequency of eat out & amount of energy intake), the factors that influences on the relation between sleeping time and obesity along the shift work were investigated by performing logistic regression analysis and analyzing odds ration after classifying them into model #1 which corrects gender, sleeping time and work pattern only, model #2 which corrects the interaction between sleeping time and work pattern only to model #1 and model #3 which corrects all factors. It showed the significant difference statistically in gender & sleeping time in case of model #1 which corrects gender, sleeping time and work pattern only and the probability of male of having obesity was higher than female by 2.5 times(95% CI 2.08-3.14) and sleeping time was higher by 1.4 times(95% CI 0.88-1.49) in case of less than 6 hours based on above 8 hours. It showed the significant difference statistically in gender & sleeping time in case of model #2 which corrects the interaction of work pattern only from model #1 and the probability of male of having obesity was higher than female by 2.5 times(95% CI 2.07-3.14) and sleeping time was higher by 1.2 times(95% CI 0.96-1.74) in case of less than 6 hours based on above 8 hours. It showed the significant difference statistically in gender, educational level & sleeping time in case of model #3 which corrects all factors and the probability of male of having obesity was higher than female by 2.3 times(95% CI 0.45-0.94) and the difference of educational level was significant as it showed 0.65 times(95% CI 0.45-0.94) and 0.66 times(95% CI 0.45-0.98) each in cases of above high school graduates and university graduates based on below middle school graduates. Regarding sleeping time, the probability of having obesity was higher by 1.5 times(95% CI 1.11-2.03) in case of less than 6 hours based on above 8 hours of sleeping time. As the result of interacting between work pattern and sleeping time, the result of comparing sleeping time and obesity along shift work and normal work between model #2 and #3 did not show the significant difference statistically.
