Diet & Health Behavior Change to Improve Bone Health

In the U.S., osteoporosis and low bone mass currently affect more than 54 million adults aged ≥ 50 y, and this is projected to increase to 71.4 million by 2030.* Those that have it often have back pain and reduced quality of life, and increased healthcare costs.

Osteoporosis increases risk of age-related fracture (small break in a bone), particularly hip fracture, which can lead to long-term disability, institutionalization and mortality. Many nutritional factors contribute to bone development during childhood and early adulthood, as well as to the maintenance of the adult skeleton. Better understanding of how diet (what you eat) and bone are linked, will help in both the promotion of bone health and the prevention of osteopenia, osteoporosis, and skeletal fractures in late life.

This aims of this study are:

  1. Develop a dietary quality index predictive of bone health and to examine cross-sectional associations between the bone-specific dietary quality index and bone mineral density (BMD) using data from the National Health and Nutrition Examination Survey (NHANES).
  2. Adapt the bone-specific index to reflect ethnic-specific food choices that may influence bone status among Caribbean Hispanics using data from the Boston Puerto Rican Osteoporosis Study (BPROS).
