As far as I know not specifically as a separate subject, but very likely to come up when in other topics such as PSHE or History. (e.g. when you do Florence Nightingale or Victorians, bound to be discussed as a key difference to today.) That said the curriculum is about to change!
I try to cover it through topics like FairTrade, where you can look at power issues. Also, looking at history topics such as slavery, civil rights and even things like Ancient Greece and Egypt can provide opportunities to point out that equality is not always the norm. SEAL work on rights and responsibilities can touch on it too. However, where there will be time or opportunity in the proposed new history curriculum I have no idea. I would encourage anyone who thinks social and global history to be important and relevant to respond to the National Curriculum consultation. It is open until 16/4. Can't link, sorry, but the proposals for history are shockingly bad: British history as a succession of British dead, white, males; wars; Crusades; and acts of Parliament - all to be taught sequentially.... Beggars belief.
We recently had a guest come into our class for the morning, who had severe burns/disfigurement due to a terrible accident in his youth. In session one he was very serious, talked about the pain, the struggle with daily life, etc. Then, in session two, he did a really fantastic workshop on beauty and the media's portrayal of attractiveness. The kids were hooked and we've had several good pshe sessions since, which have led from media beauty into gender roles, expectations based on ender, etc. So, so beneficial to the children.
If you're a teacher and would be interested in similar workshops for your school, pm me.
