Multiple linear regression assessed BMD, and Cox regression models estimated fracture risk. Restricted cubic splines were used to evaluate non-linearity. Participants\u2019 average age was 56\u00b70 years, with 1097 hip fractures and 7889 all fractures recorded over 12\u00b70 years of follow-up. Complex inverted U-shaped associations between UPF intake and BMD were found at the femur trochanter. Compared with the lowest UPF intake, the highest UPF intake was linked to a reduction in BMD at the femoral neck (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    (\n                    <jats:sc>se<\/jats:sc>\n                    ) = \u22120\u00b70061 (0\u00b70024),\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0\u00b705), femur trochanter (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    (\n                    <jats:sc>se<\/jats:sc>\n                    ) = \u22120\u00b70083 (0\u00b70024),\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0\u00b7001), lumbar spine (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    (\n                    <jats:sc>se<\/jats:sc>\n                    ) = \u22120\u00b70114 (0\u00b70036),\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0\u00b701) and total body (\n                    <jats:italic>\u03b2<\/jats:italic>\n                    (\n                    <jats:sc>se<\/jats:sc>\n                    ) = \u22120\u00b70095 (0\u00b70021),\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0\u00b7001).
