Background:
Studies on yawning during menstrual cycle are lacking.
 
Objectives:
To find out the frequency of yawning among adolescent girls during menstrual cycle and to correlate with the various symptoms during menstruation.
 
Material and Methods:
Adolescent girls were enlightened about the study and informed consent was obtained for their participation. They were asked to note down the frequency of Yawning in a structured proforma during the period of menstruation (from the first day to last day). Again they were asked to record the frequency of yawning 4 days after the last menstrual day for three consecutive days. The average episodes of yawning during menstrual period and pre-ovulatory period per day were calculated for each subject and compared with each other.
 
Results:
Out of the 200 girls (age range 18 to 22 and median age 19 years) addressed, 188 agreed to participate in the study. Out of them, the proforma was completed on all the aspects in 150 only. Thus, the response rate was 79.8%. The frequency of yawning was significantly (P<0.01) more among girls during the period menstruation when compared to pre- ovulatory phase, and more so among those who had heavy bleeding, tiredness and a sense of sleepiness.
 
Comments:
Increased frequency of yawning during the period of menstruation among adolescent girls may likely to be related to the neurohormonal mechanisms involved both in yawning and menstrual cycle. However, further studies are warranted to confirm or refuse the observation/hypothesis.
