¹Means were estimated from linear regression models adjusted for age, BMI, race-ethnicity, calibrated energy intake, general health, physical activity, history of fracture at age ≥55 y, history of parental fracture, current smoking, corticosteroid use, glucocorticoid use, treated diabetes, rheumatoid arthritis, and hormone use. BMD, bone mineral density; WHI, Women's Health Initiative.
