We investigated the influence of skin pressure by clothing on the duration of menstrual cycle with 33 young adult women. The average age was 19.9 ± 2.1 years (mean ± SD), stature 159.5 ± 5.6cm and body mass 50.9 ± 5.5kg. Thirty-three women participated as subjects. They wore their usual clothing including foundation garments, panty stocking, pants or skirt and T-shirt or blouse and cardigan for the first 4 months from December to March ('Tight 1'). For the second 4 months from April to July, the women wore loose clothes, i.e., they did not wear foundation garments at home. Skirt and jeans were worn loosely ('Loose'). For the last 4 months, from August to November, they wore their clothes as tightly as possible, compared to 'Tight 1' ('Tight 2'). Each participant marked the first day of the occurrence of menses in the pocket diary throughout the year. The main results were summarized as follows: 1) The average duration of the menstrual cycle was 44.2 ± 14.9 days (mean ±) in 'Tight 1', 30.4 ± 3.0 days in 'Loose' and 47.4 ± 22.7 days in 'Tight 2'. 2) The number of months when the menses did not occur was 38 for 'Tight 1', 6 for 'Loose' and 40 for 'Tight 2'. 3). The number of participants who had a duration of the menstrual cycles for more than 40 days, was 25 participants for 'Tight', 10 for 'Loose' and 29 for 'Tight'. It can be concluded that skin pressure by clothing could disturb the duration in the menstrual cycle.
