Comparison of the proportions of participants with menstrual cycle onset in the light and dark periods showed no significant differences in the higher BMI group (BMI ? 20.5, n = 260, light period: 386 (50%), dark period: 383 (50%), z = 0.11, p = 0.91) or the lower BMI group (BMI < 20.5, n = 269, light period: 382 (48%), dark period: 408 (52%), z = ?0.93, p = 0.36).

New binominal sample revealed that brand new ratio of good sleepers having menstrual cycle beginning for the white period try significantly more than one for the dark period (z = dos.30, p = 0.02), because ratio of bad sleepers that have menstrual period beginning while in the this new ebony several months are significantly more than one when you look at the white period (z = ?2.66, p = 0.01).
Comparisons between good and poor sleepers showed no significant differences in mean age (good sleepers: 31.6 years old, poor sleepers: 31.5 years old, t(527) = 0.20, p = 0.85), BMI (good sleepers: 21.1, poor sleepers: 21.6, t(527) = ?0.84, p = 0.40), or menstrual cycle length (good sleepers: 29.9 days, poor sleepers: 30.2 days, t(527) = ?1.66, p = 0.10). Physical health component summary (PCS), mental health component summary (MCS) , and menstrual symptom (the modified Menstrual Distress Questionnaire (mMDQ)) scores were significantly worse among poor sleepers than among good sleepers (PCS: 50.4 vs. 47.8, t(527) = 4.39, p < 0.001; MCS: 46.1 vs. 40.8, t(527) = 7.65, p < 0.001; mMDQ: 27.4 vs. 38.3, t(527) = ?6.69, p < 0.001).
On the other hand, we classified the new Pcs, MCS, and you will mMDQ results on highest and you can lowest groups and you may opposed the brand new level of menstrual cycle onsets inside the light and you will dark attacks.
