Osteoporosis is a major public health concern for U.S. women. 85 Hispanic (H) (29.6 ± 6.7 y; BMI 28.8 ± 6.9 kg/m 2 ; n=42) and Caucasian (C) (30.9 ± 6.1 y; BMI 27.9 ± 7.3 kg/m 2 ; n=43) women were recruited from the local community. Bone mineral density was measured by DEXA (Lunar/GE Prodigy). Participants completed a 7‐d weighed food record and wore a pedometer (Yamax) for 7‐d. No differences were seen in bone health by ANCOVA between the two ethnic groups when adjusted for dietary calcium and body weight (mean femur neck T‐scores, H = −0.02 ± 0.85, C = 0.07 ± 0.77; mean Ward's Triangle T‐scores, H = 0.17 ± 1.09, C = 0.20 ± 1.06; mean trochanter T‐scores, H = −0.19 ± 0.86, C = −0.17 ± 0.91; mean spine T‐scores, H = 0.25 ± 0.93, C = 0.44 ± 1.00). However, osteopenia occurred in 6 (14%) H and 3 (7%) C (femur neck); 6 (14%) H and 6 (14%) C (Ward's triangle); and 6(14%) H and 12 (28%) C (trochanter). Dietary calcium intakes were not different between groups (H = 768 ± 266, C = 814 ± 284 mg/d); 33 (87%) H and 30 (75%) C women had 7‐day average intakes below the calcium AI (1000 mg). Only 9 (21%) H versus 20 (47%) C women reported using a calcium supplement. Average steps/d did not differ between groups (H = 6671 ± 2489, C = 7868 ± 3735 steps/d); only 4 (11%) H and 10 (25%) C women completed over 10,000 steps/day. Dietary calcium was poor for both groups; fewer H women consumed a calcium supplement. Fewer H women completed 10,000 steps/day. Osteopenia was diagnosed in both C and H women. Thus, all young women, regardless of ethnicity, need to improve physical activity and consume nutrients important for bone health.
