This analysis examines the association between dietary calcium intake and total femur bone mineral density (BMD) using data from the NHANES 2017–2018 cycle. Using simple linear regression, we estimate the direction and magnitude of the calcium–BMD relationship, test whether the association is statistically distinguishable from chance, and generate predicted BMD values at a clinically meaningful calcium intake level. The dataset includes 2,129 adults after excluding observations with missing values on BMD or calcium. Results are interpreted in the context of bone health research, with attention to model fit, prediction uncertainty, and the limitations of drawing causal conclusions from a cross-sectional survey.
