Table 2. Comparison of Type D personality and depression scores and rates between the groups
Correlation analysis showed a negative correlation between PMSS score and age at menarche (r=-0.1, p=0.02) and a positive correlation between PMSS score and the volume of menstruation (r=0.1, p=0.04), BDI-21 (r=0.4, p<0.0001), NA (r=0.3, p< 0.0001) and SI score (r=0.2, p<0.0001). NA and SI scores were also strongly correlated with BDI-21 score (p<0.0001) (Data not shown). Regression analysis was performed to investigate the association between Type D personality and PMS. A positive association between Type D personality and PMS persisted after the adjustment of age, BMI, age at menarche, duration of menstruation and cycle, volume of menstruation, regularity of menstruation, smoking, alcohol, sportic activity (p=0.02, OR[95%CI]=2.05[1.08-3.86]). Depression (p<0.0001, OR[95% CI]= 6.23[3.28-11.85]) and volume of menses (p=0.02, OR [95% CI]=1.28 [1.03-1.6]) were also positively associated with the presence of PMS Table 3.
