[Factors causing fatigue in female industrial workers]

In 1698 female workers aged 18-45 a relationship was sought between subjective symptoms of fatigue and factors which directly or indirectly could affect them: age, Hb level, relative body weight, health status, abundance of menstrual bleedings. In 199 women the number of sleep hours and stress in occupational work was taken into account. A strong relation was found between fatigue and age of women. The role of the remaining factors was evaluated after standardisation for age. The occurrence of fatigue was highly statistically dependent on the health status and abundance of menstrual bleedings. The other relations were less pronounced.
