The researcher intended to investigate the rate of absenteeism and other related statistics among the workers in a steel and iron industry with the criteria and the recommendation of the International Association on Occupational Health.
With the well designed questionaire and interview, 1,882 workers were surveyed from July the 24th to the 28th, 1978.
The results were as follows;
The workers who experienced absence were 16.8% in July. The rate of frequency (spells) was 3.24, the duration was 4.65, the frequency (persons) was 345.20, and the lost time was 1.27.
41.0% among the absentee experienced sickness absences, and the rates of sickness absence were as follow; the frequency (spells) was 1.34, the duration was 2.29, the frequency (persons) was 101.06 and the lost time was 0.63, respectively.
The main causes of sickness absence were general symptoms, such as fatigue (50.8%) and gastro-intestinal symptoms (13.8%). The frequency of sickness was highly correlated to the frequency of drinking, the amount of smoking, the physical work-load and the amount of drinking, which was analysed by the stepwize multiple regrssion analysis. The multiple R due to the above mentioned four variables was 0.320 and the R square was 10.3%.
