Perimenopausal Night Sweats Study

Too young for night sweats? If so, we are inviting you to join a new study conducted by UBC endocrinologist Dr. Jerilynn Prior.

Already a participant? Enter our password-protected participants’ lounge to download resources, view the instructional video, and pass along your comments & questions. If you haven't already received the login/password details, please contact Dr. Hitchcock at 604-875-5917 or email chris.hitchcock@ubc.ca.

The primary aim of the study is to determine the feasibility of a potential future randomized control trial of progesterone therapy in perimenopause, and to estimate the number of women who would be needed for that study, as well as to examine whether cyclic hormonal changes affect perimenopausal night sweats.

This is a great opportunity to learn more about yourself and help us understand night sweats in women aged 35-50 who still have regular periods.

This UBC study is observational (no study medications), and takes 4 menstrual cycles.

Who can participate?

You may be eligible for the study if you are a woman who:

  • Is between age 35 and 50
  • Had menstrual periods no more than 60 days apart in the past year
  • Is not taking hormone therapy or birth control
  • Has night sweats (hot flushes during sleep time)

What will I be asked to do?

  • Visit our office (at VGH) for an hour-long interview session
  • Keep a daily record (the Daily Perimenopause Diary) for 4 menstrual cycles
  • Record the first morning temperature
  • Collect a small amount of urine each morning for the first full menstrual cycle
