Abstract

BACKGROUND:

Cardiovascular disease (CVD) and osteoporosis are 2 major public health problems that share common pathophysiological mechanisms. It is possible that strategies to reduce CVD risk may also benefit bone health.

OBJECTIVE:

We tested the hypothesis that adherence to the 2006 American Heart Association Diet and Lifestyle Recommendations (AHA-DLR) is associated with bone health.

DESIGN:

We previously developed a unique diet and lifestyle score (American Heart Association Diet and Lifestyle Score; AHA-DLS) to assess adherence to the AHA-DLR. In a cross-sectional study of 933 Puerto Ricans aged 47-79 y, we modified the AHA-DLS to test associations with bone health. Bone mineral density (BMD) at the femoral neck, trochanter, total hip, and lumbar spine (L2-L4) was measured by using dual-energy X-ray absorptiometry.

RESULTS:

For every 5-unit increase in the modified AHA-DLS, BMD at the femoral neck, trochanter, total hip, and lumbar spine (L2-L4) was associated with a 0.005-0.008-g/cm(2) (P < 0.05) higher value. No component of the AHA-DLR alone was responsible for the observed positive associations. For every 5-unit increase in the modified AHA-DLS, the odds for osteoporosis or osteopenia at the trochanter, total hip, and lumbar spine (L2-L4) were lower by 14% (OR: 0.86; 95% CI: 0.79, 0.92), 17% (OR: 0.83; 95% CI: 0.76, 0.92), and 9% (OR: 0.91; 95% CI: 0.84, 0.99), respectively.

CONCLUSIONS:

Dietary guidelines for CVD risk reduction may also benefit bone health in this Hispanic cohort. Synchronizing dietary guidelines for these 2 common diseases may provide a simplified public health message. This trial was registered at clinicaltrials.gov as NCT01231958.
