Influencing factors of dysmenorrhoea among hospital nurses: a questionnaire survey in Taiwan

OBJECTIVES Nurses are at high risk of dysmenorrhoea while working with patients. The study objectives were to: (1) describe the demographic and menstruation characteristics of dysmenorrhoea, knowledge about dysmenorrhoea and menstrual attitudes towards menstruation among dysmenorrhoeal and non-dysmenorrhoeal hospital nurses; (2) identify significant differences between the groups; and (3) examine factors influencing dysmenorrhoea. METHODS This cross-sectional survey used a structured questionnaire, administered at two hospitals in southern Taiwan. Participants included hospital nurses at least 18 years of age who agreed to participate. All participants were recruited through random sampling. The questionnaire included demographic data, the Dysmenorrhoea Knowledge Scale and Menstrual Attitude Scale (MAS). RESULTS A total of 420 nurses completed the questionnaire. Among them, 297 (70.7%) had experienced dysmenorrhoea in the past 6 months and 123 (29.3%) had not. Significant differences in age (P<0.001), marital status (P<0.001), childbearing status (P<0.001), age at menarche (P<0.05) and rotating three shift ratio (P<0.05) were identified between the dysmenorrhoea and non-dysmenorrhoea groups. Analysis of the MAS results revealed significant differences between the groups regarding consideration of menstruation as a debilitating (P<0.001) or bothersome event (P<0.05), anticipation and prediction of menstruation onset (P<0.01) and denial of any effects from menstruation (P<0.001). Results of the multiple logistic regression showed that predictive factors included age <40 years (4.46 vs 1.00), working three shift rotations (2.07 vs 1.00), marital status (2.59 vs 1.00), acknowledging menstruation as a debilitating event (2.72 vs 1.00) and denial of effects from menstruation (2.59 vs 1.00). CONCLUSIONS These findings could help nursing managers to create a caring and friendly work environment for hospital nurses at risk of dysmenorrhoea.
