this was in the news yesterday but i didn't have time to post about it
this is the bbc report www.bbc.co.uk/news/health-32350566
press release from UCL www.ucl.ac.uk/news/news-articles/0415/200415-emotional-problems-girls-rose
peer-reviewed article (behind paywall) www.jahonline.org/article/S1054-139X(15)00064-6/fulltext
it's a comparison of two questionnaires, one completed in 2009 and one in 2014, indicating a sharp rise in reported emotional problems in girls aged 11-13
the researchers suggest that reasons for this could be "increasing stresses on girls and young women, ranging from academic pressure to their increasing sexualisation and objectification amplified by social media"
it's both worrying and not surprising IMO
