Relationship between serum vitamin D with severity of primary dysmenorrhea and associated systemic symptoms in dormitories students of Shahid Beheshti University of Medical Sciences

Some studies have shown the relationship between vitamin D3 deficiency, with primary dysmenorrhea and associated systemic symptoms. However, the relationship between pain severity and serum vitamin D level is not known. Therefore, this study was performed with aim to investigate the relationship between the severity of primary dysmenorrhea and associated systemic symptoms with serum levels of vitamin D. This cross-sectional study was performed on 143 students with primary dysmenorrhea in dormitories of Shahid Beheshti University of Medical Sciences in 2018. Data related to menstruation cycle and severity of primary dysmenorrhea were collected using demographic questionnaire, menstrual status and pain index. The serum level of 25-hydroxyvitamin D3 was determined by LIASON device, by Chemiluiminescence method and was analyzed in DiaSorin kit. Data were analyzed by SPSS software (version 24) and Mann-Whitney test and independent t-test. P No significant relationship was found between the mean score of primary dysmenorrhea and serum vitamin D levels (P>0.05). There was a significant relationship between severity of headache, fatigue, nausea and vomiting with serum vitamin D levels (P <0.001), but this relationship was not found with severity of diarrhea (P>0.05). There is no significant relationship between severity of primary dysmenorrhea and serum vitamin D levels, but significant relationship was found with severity of headache, fatigue, nausea and vomiting. Performing larger studies in a non-homogeneous society is suggested for closer evaluation of this relationship.
