Regression models are adjusted for race, clinical site, baseline age, baseline menopausal stage (pre- vs. early perimenopausal), baseline body mass index, smoking, baseline alcohol intake, presence of prevalent fracture, calcium and vitamin D supplement use, physical activity, and use of medications known to influence bone density. High school education or less than high school education was reported by 293 non-Caucasian women and 166 Caucasianwomen. Information regarding educational level was missing for nine non-Caucasian women and for four Caucasian women
