We aimed to study the effect of soft drink consumption on BMD at 4 hip sites in 273 men and 698 women in the Boston Puerto Rican Osteoporosis Study using dual‐energy X‐ray absorptiometry (DXA). Soft drink intakes were captured by food frequency questionnaire (FFQ). The mean intake of soft drinks was 2.2 ± 4.3 and 1.5 ± 3.0 servings/week, for men and women, respectively. Total intake of cola beverages was significantly associated with lower BMD at the total hip (β= ‐0.004, P‐value 0.002), trochanter (β= ‐0.003, P‐value 0.03) and femoral shaft (β= ‐0.01, P‐value 0.0005), but not at the femoral neck. Intake of diet‐cola was also significant at the femoral shaft and approached significance at the total hip and trochanter. In contrast, non‐cola soft drinks were not significantly associated with any hip measure. Our models were adjusted for age, sex, BMI, height, calcium‐vitamin D supplement use, dietary calcium intake, smoking, alcohol use, total energy intake, physical activity, and season of BMD measurement. In conclusion, the effect of cola, but not other soft drinks suggests that phosphoric acid may have a negative effect on bone statusGrant Funding Source: This study was supported by the National Institutes of Health grants P01 AG023394, P50 HL105185 and
