Menstruation and industrial efficiency. I. Absenteeism and activity level

Abstract

96 women in aircraft, parachute, and garment factories were used to study the relationship between the menstrual cycle and activity level and absence rate. The results indicated that: (1) there were no discernible changes in activity level in any of the factories; (2) in the parachute factory, there were low menstrual absence rates, but high post-menstrual rates; (3) in the aircraft factory, no significant trend; (4) in the garment factory, high menstrual absences, but low premenstrual. Possible explanations of the results are discussed. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
