Objectives: In this study our main goal is to evaluate the sociodemographic characteristics of PMS patients.

Methods: This cross-sectional observational study was done in the department of Physiology, Chittagong Medical College, over one-year period from January, 2017 to January, 2018. Total 90 subjects between 18-22 years were selected by purposive sampling according to inclusion and exclusion criteria from the 1^st year female medical students. They were divided in anaemic (Group A) and non anaemic (Group B) on the basis of haemoglobin concentration.

Results: Mean (±SD) weight of the subjects were 53.12 ± 10.4 Kg and 53.56 ± 10.3 Kg in group A and group B respectively. Mean (±SD) TSH of the subjects were 0.98 ± 0.52 mIU/L and 0.90 ± 0.38 mIU/L in group A and group B respectively. Also, in anaemic group 39% had dysmenorrhoea while in non anaemic group 36% had dysmenorrhea.

Conclusion: From our study we can conclude that larger sample size, among different age group and professions, for an extended period including different hormonal assay and study of neurotransmitters with follow up of the subjects after supplementation of haematinics should be continued to find out the causal factors of PMS.
