For each\n subscale, questions were \nasked concerning the month prior to interview and lifetime prevalence (\u2018ever\u2019).<\/jats:p><jats:p><jats:bold>Results.<\/jats:bold> Model fitting indicated that there is a powerful \nrole of the environment in shaping women's \nattitude towards weight, shape, eating and food, ranging from 38% to 100%\n of the variance. For \nall subscales, with the exception of weight concern, the best \nexplanation for individual variation was \none that incorporated additive genetic and non-shared environmental \ninfluences. In contrast, model \nfitting indicated that non-shared and shared environmental influences best\n explained the variance \nof weight concern.<\/jats:p><jats:p><jats:bold>Conclusions.<\/jats:bold> With the exception of the Shape Concern \nsubscale, environmental factors make a \ngreater contribution than genetic factors to the development of \nthe overvalued ideas that are seen \nto be one of the triggers for the development of bulimia nervosa. \nGiven this substantial role of the \nenvironment influences, it seems likely that environmental manipulation\n can be effective in the \nprevention of bulimia nervosa.<\/jats:p>","DOI":"10.1017\/s0033291798006989","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:36:08Z","timestamp":1027776968000},"page":"761-771","source":"Crossref","is-referenced-by-count":57,"title":["Genetic and environmental risk factors for the weight \nand shape concerns characteristic of bulimia nervosa"],"prefix":"10.1017","volume":"28","author":[{"given":"T.","family":"WADE","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.
