Reduce the proportion of adults with osteoporosis — O‑01 Data Methodology and Measurement

About the National Data

Data

Baseline: 7.3 percent of adults aged 50 years and over had osteoporosis in 2013-14

Target: 5.5 percent

Numerator
Number of adults aged 50 years and over with a femoral neck bone mineral density (BMD) value less than or equal to 0.56 gm/cm2.
Denominator
Number of adults aged 50 years and over.
Target-setting method

Minimal statistical significance

Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because recent data suggested an increase or leveling off in osteoporosis prevalence. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because the Healthy People 2030 Workgroup Subject Matter Experts expected the data to continue to be difficult to change, so a conservative target was selected.

Methodology

Methodology notes

Bone mineral densities are determined from measurements made as part of the NHANES battery of examinations. The choice of a femoral BMD of 0.56 or less is the measure of 2.5 or more standard deviations below the reference mean for young adults aged 20-29 years.

History

Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.
