Brief description of study

The purpose of this study is to examine how depression symptoms develop when women begin the transition to menopause. This study will investigate depression symptoms by looking at how fluctuations in reproductive hormones (specifically, the hormone estradiol) might impact the body's biological sleep rhythms. This study will also look at how regularity of daily routines (like mealtimes, social interactions) and life stressors (like taking care of family members, employment concerns) can be another way in which these symptoms may develop.
