An interesting publication where the vitamin D status is compared in 34 children aged 9-24 months living in a region of Delhi known for high levels of air pollution (Mori Gate), with a comparable age range of less pollinated children (Gurgaon) from the city.

The mean value of 25 (OH) D in the Mori gate area was 12.4 (7) ng / ml, compared with 27.1 (7) ng / ml in children living in Gurgaon District (p <0.001 ).

The authors recommend that children living in areas with high atmospheric pollution should be offered vitamin D supplements because they are at risk of developing vitamin D deficiency rickets.
