A Prospective Exploration of Cognitive Dietary Restraint, Subclinical Ovulatory Disturbances, Cortisol, and Change in Bone Density over Two Years in Healthy Young Women

Context: Cross-sectional studies have found associations among elevated cognitive dietary restraint (CDR), increased ovulatory disturbances, and lower bone mass, possibly mediated by cortisol. Objective: To determine whether healthy young women with higher CDR have more menstrual cycles with subclin...

Description
Summary:Context: Cross-sectional studies have found associations among elevated cognitive dietary restraint (CDR), increased ovulatory disturbances, and lower bone mass, possibly mediated by cortisol. Objective: To determine whether healthy young women with higher CDR have more menstrual cycles with subclinical ovulatory disturbances (SOD), elevated 24-h urinary free cortisol (UFC), and less positive 2-yr areal bone mineral density change (Δ-aBMD). Design, Setting, and Participants: We conducted a 2-yr longitudinal study of 123 healthy, community-dwelling, nonobese, regularly menstruating women aged 19–35 yr. Main Outcome Measures: Key variables were Three Factor Eating Questionnaire Restraint score, percent of cycles with anvoluation and/or luteal phase length
