Building peak bone mass through young adulthood is important in the prevention of osteoporosis. This study examined if bone quality was associated with calcium (Ca) intake, restrained eating and physical activity in a group of 99 young adult women. Caucasian volunteers, 20–29 years of age completed a Block Food Frequency Questionnaire, Dutch Eating Behavior Questionnaire (DEBQ) and the International Physical Activity Questionnaire. Heights and weights were measured using standard procedures, and calcaneus stiffness index (SI) scores were recorded using an Achilles Insight GE quantitative ultrasound. Participants had a mean ± SD age, height, weight, BMI, bone quality, restrained eating and physical activity of 21.5 ± 1.7 yrs, 164.0 ± 6.4 cm, 61.4 ± 9.2 kg, 22.8 ± 2.7 g/m 2 , 100.5 ± 15.7 SI, 26.6 ± 7.4 restrained eating DEBQ score and 1523.4 ±1346.8 MET‐min/wk, respectively. Mean ± SE Ca intake was higher among women who supplemented versus those who consumed only dietary Ca (980.11 ± 488.4 mg and 932.2 ± 487.2 mg, respectively (P=0.04)). Based on the EAR, neither group was at risk for inadequate Ca intake. Multiple linear regression controlled for body weight indicated that SI score was not associated with Ca intake, restrained eating or physical activity. Bone quality in this group of young adults was not related to behavioral factors commonly associated with bone health. Funded in part by Federal Hatch Act Funds # LAB 93846
