RT Journal Article T1 Type of Dysmenorrhea, Menstrual Characteristics and Symptoms in Nursing Students in Southern Spain A1 Abreu Sánchez, Ana María A1 Parra Fernández, María Laura A1 Onieva Zafra, María Dolores A1 Ramos Pichardo, Juan Diego A1 Fernández Martínez, Elia AB Dysmenorrhea is a form of chronic pain associated with menstruation that affects ahigh percentage of young people. This study sought to determine the prevalence of primary andsecondary dysmenorrhea among female nursing students in southern Spain and to compare theirmenstrual characteristics and symptoms. A cross-sectional observational study was conducted usinga self-report questionnaire that included sociodemographic variables, menstrual characteristics andrelated symptoms. Descriptive bivariate analysis and binary logistic regression were performed inwhich the dependent variable was secondary dysmenorrhea. The prevalence of dysmenorrhea was73.8% (of which 63.3% had primary dysmenorrhea and 10.5% had secondary dysmenorrhea), and wasmore likely in women with longer periods, heavier bleeding and those not using oral hormonalcontraception (OCP). Secondary dysmenorrhea was 31.75, (confidence interval (CI)95% = 4.44–238.59;p < 0.01) times more likely among those with menstrual headache, 8.37 (CI95% = 2.35–19.80; p < 0.01),times greater among those suffering nausea during menstruation, 6.60 (CI95% = 1.42–30.67; p < 0.01),times greater among those suffering from menstrual vomiting, it was also 1.17 (CI95% = 1.08–1.26;p < 0.01) times more likely for each day that the period was prolonged and 6.63 (CI95% = 1.47–30.01;p = 0.014) times more likely in women with a heavy menstrual flow. These findings may helpguide professionals towards the prescription of additional tests in certain cases in which secondarydysmenorrhea is suspected.
