Eating disorders (EDs) are now often approached as biopsychosocial problems, and are widely recognised as multifactorial in origin. But it has been suggested -particularly by feminist scholars -that all is not equal within this biospsychosocial framework, with the 'social' aspects of the equation relegated to secondary or facilitating factors in treatment contexts. Drawing on data from 12 qualitative interviews with health professionals in a UK region, this article examines the extent to which socio-cultural perspectives on eating disorders (EDs) are valued and explored in ED treatment, with a particular focus on questions of gender (and femininity).Given that girls/women are disproportionately affected by EDs, the article explores to what extent the relationship between EDs and cultural constructions of femininity is actively 2 addressed within treatment. The study revealed high levels of inconsistency in this regard, in so far as some health professionals thought that such issues should be central to treatment, whereas others had 'never really considered' them before. In addition, the study examines the potential limitations to the ways in which such socio-cultural issues are perceived and addressed. Not only was the onus often on the patient to flag the relevance of such issues (rather than these being anticipated and embedded within treatment), but socio-cultural perspectives on EDs were covered little in training, making it potentially difficult for health professionals to know when such concerns were being raised. Furthermore, in drawing on the interview data, the article explores why the often 'obvious' relationship between femininity and EDs may currently be marginalised in treatment, building on a feminist critique of what counts as 'evidence-based' treatment and why.
