Background Dysmenorrhea, characterized by painful menstruation, can influence body composition, muscle strength, and metabolic function. This study aimed to investigate differences and relationships between body composition variables, phase angle (PhA), muscle strength, and urine metabolites among Japanese female individuals with and without dysmenorrhea. Methods Thirty-four participants, divided into healthy menstruating control (n = 15) and dysmenorrhea (n = 19) groups, were included. PhA, whole body lean soft tissue (WB LST), visceral fat (VF) and subcutaneous fat (SF), hand grip strength (HGS), leg strength, and urine metabolites were measured using multifrequency bioelectrical impedance analysis, dual-energy X-ray absorptiometry, computed tomography, dynamometry, and liquid chromatography, respectively. Results No significant differences were found in the characteristic variables. BMI, PhA, and muscle strength showed a positive association only in the control group. However, menstrual status (control/dysmenorrhea, 0/1) did not affect muscle strength. Conversely, a negative coefficient (LASSO: -0.098; Elastic net: -0.109) demonstrated that the dysmenorrhea group had lower predictive PhA values than did the control group. PhA and WB LST were identified as meaningful predictors of HGS (R2 = 0.433) and leg strength (R2 = 0.251). Acylcarnitine metabolites were positively associated with VF and PhA in the dysmenorrhea and control groups, respectively. Conclusion The study findings highlight distinct associations among body composition, PhA, muscle strength, and urinary metabolites in these female groups. However, the study is limited by the absence of severity of dysmenorrhea symptoms, phases of menstruation, and no adjustment for lifestyle factors. A future longitudinal study is warranted to understand these physiological association between the control and dysmenorrhea groups.
