Call for body image lessons in UK schools 10 October 2013 Last updated at 03:36 By Helen Briggs BBC News The self-esteem of teenage girls could be improved by training teachers to deliver classes in body image, a UK study shows. In the pilot study, 261 teenage girls at three secondary schools were given a course of six lessons on body image. This had significant effects on their body image and self-esteem compared with the regular curriculum, say psychologists at King's College London. As many as one in three teenagers say they are dissatisfied with their body. Poor body image has been associated with depression, eating disorders, overuse of cosmetic surgery, obesity and unhealthy weight loss behaviours. We're hopeful that as we continue with this research that we'll be able to make the programme even more effective and that it could then go on to be effective in reducing disordered eating  End Quote Dr Helen Sharpe King's College London Dr Helen Sharpe and colleagues at the Institute of Psychiatry developed a course on positive body image for teenage girls. The six-part programme focused on ideals of beauty, unhealthy interactions with peers - such as "fat talking," or making negative comments about weight - and practical measures for boosting mood and self-esteem. The course was delivered by teachers in three state-funded girls' schools. Dr Sharpe told the BBC: "We have tested whether a series of lessons being delivered by teachers to students in school are helpful in improving body esteem - we found this was the case." She said the research, published in The British Journal of Psychiatry, showed promise in being able to tackle problems caused by low body esteem, such as eating disorders. "We're hopeful that as we continue with this research we'll be able to make the programme even more effective and that it could then go on to be effective in reducing disordered eating - things like binge eating and unhelpful weight loss," said Dr Sharpe. Interventions delivered by teachers would have wide reach and be of minimal cost, said the researchers. MP recommendations Some schools were relying on programmes that were not evidence-based and could be harmful, they added. Last year, MPs recommended that all schoolchildren should take part in compulsory body image and self-esteem lessons. An inquiry by the All-Party Parliamentary Group on Body Image heard evidence that more than half of the public had a negative body image. Girls as young as five now worried about how they looked, the MPs' report said, while cosmetic surgery rates had increased by nearly 20% since 2008.
