Premature babies are at risk of osteopenia due to lack of minerals normally accumulated in the last trimester. This increases the risk of fractures in the short-term and short stature in the long-term.
All enterally fed very preterm babies should receive phosphate as a supplement to breast milk in addition to their routine vitamin D.
