Dysmenorrhea: Relationship to Body Mass Index (BMI) and Blood Pressure

A. Omorogiuwa, O.A Ekhegbesela

Abstract


Dysmenorrhea constitutes a major gynecological challenge amongst adolescent and young adult females. The use of Non Steriodal Antiinfamatory Drugs (NSAIDS) has been identified as the commonest group of drugs for the management of dysmenorrhea amongst Nigerian
undergraduates. NSAIDS and BMI are close associates of cardiovascular disease like high blood pressure. This study investigates the effect of BMI and blood pressure on dysmenorrhea. We carried out a cross sectional study on 240 undergraduates that were selected by a multistaged sampling technique. We obtained ethical approval from the ethical committee of the university. Subjects gave informed consent for the study and we gave them a semi-structured questionnaire for the study. Blood pressures, weight and the height of the subjects were measured respectively with sphygmomanometer, bathroom scale Hana BR-9011 UK and a standard standiometer. BMI was equal to weight(Kg)/height 2 (m). 158 (77.5%) had dysmenorrhea while 46 (22.5%) had eumenorrhea. The mean age of the subjects with dysmenorrhea was 19.16 + 2.98 while the mean age of the subjects with eumenorrhea was 19.97 + 2.43 (p = 0.07). The mean ages for menarche for subjects with dysmenorrhea andeumenorrhea were12.49+2.43 and 12.51+ 2.41 respectively (p = 0.961).The BMI for subjects with dysmenorrhea and eumenorrhea were 21.28 + 1.02 Kg/m 2 and 20.74+ 2.12 Kg/m 2 (p = 0.017). The difference in the blood pressures for eumenorrheic subjects and dysmenorrheic subjects were not significant statistically. Thus, increased body mass index is a risk factor for dysmenorrhea.
