Predictive factors
IBS, Pain
Singleness decreased the RR of IBS by 0.772 (p = 0.01) but not for SxD (RR = 0.626, p = 0.1). BMI did not affect IBS (RR = 1.3, p = 0.3) or SxD (RR = 1.1, p = 0.7) women. Pain related to menses did not differ between the IBS versus control (47.06% vs. 37.04%, respectively; RR = 0.8, p = 0.3) or SxD positive and negative (37.84% vs. 44.12%, respectively; RR = 1.1, p = 0.6) groups. BSS types 3, 4 and 5 were protective factors associated with IBS compared with controls (62.75% vs. 87.04%, respectively; RR = 0.5543, p = 0.006).
