Predictors of BMD loss ≥ 5% at the lumbar spine or femoral neck in DMPA users over 24 months of use

Characteristics	Odds ratio (95% CI)
Race/ethnicity
Black	Reference
White	0.34 (0.10–1.17)
Hispanic	0.90 (0.26–3.10)
Previous DMPA injection (#)	0.90 (0.80–1.02)
Parity	0.49 (0.29–0.82)
Total calcium intake	0.81 (0.65–0.99)
Current smoker	3.88 (1.26–11.96)

Based on logistic regression analysis

R-squared value: 0.20

Area under the ROC curve: 0.79

P value for Hosmer-Lemeshow goodness of fit test=0.25

Dependent variable: BMD loss (≥ 5% vs. <5%)

Predictors: race/ethnicity (non-Hispanic black, non-Hispanic white, Hispanic), previous use of DMPA injection (# of injection), parity (continuous), total calcium intake (in 100 mg/day), current smoker (current smoker vs. not current smoker)
