At least they\’re not trying to cover up (sorry) the cause here:
Rickets, a softening of bone tissue often characterised by bowed legs, is caused by a vitamin D deficiency and was associated with Victorian slums. But a study found that there were 56 suspected cases between 2003 and 2005 in the catchment area of two primary care trusts that cover Blackburn with Darwen and Burnley, Pendle and Rossendale, in Lancashire. A large proportion of the cases came from the Asian community of Blackburn with Darwen.
Public health officials say that the problem is genetic and cultural. The religious imperative to use a hijab to cover up in public means that some women are not exposed to enough sunlight. Dr Ellis Friedman, the director of public health for East Lancashire, said rickets “is caused by a combination of skin colouration, diet and dress, not poverty”.
There\’s a reason why us adapted to northern climes have pale skin: yes, it makes us more liable to skin cancer, but less so to rickets. Add in, as they say, the covering up and….well, the usual "cure" for rickets is to drink milk isn\’t it? Something not part of the traditional South Asian diet?
