One hundred nine females with full and subthreshold AN (17–45 years old) recorded ED behavior and stress ratings over 2 weeks. Using hierarchical linear modeling, individuals with eumenorrhea and those with amenorrhea or oligomenorrhea were compared.</p> </sec> <sec id="eat22211-sec-0003" sec-type="section"> <title>Results</title> <p>Following episodes of meal skipping, momentary stress decreased in individuals with normal menstrual cycles and increased in those with irregular menstrual cycles.</p> </sec> <sec id="eat22211-sec-0004" sec-type="section"> <title>Discussion</title> <p>Results suggest that changes in stress severity in response to food restriction may differ based on ovarian hormonal status and may be a mechanism by which AN is maintained in individuals without menstrual disturbance. © 2013 Wiley Periodicals, Inc.
