The Physique Venture peer-led consuming issues prevention programme


An estimated 1.25 million folks within the UK have an consuming dysfunction (Beat, 2023a). This consists of anorexia nervosa (AN), bulimia nervosa (BN), binge consuming dysfunction (BED) and purging dysfunction (PD), that are related to quite a few unfavourable outcomes, together with suicidality, unhealthy physique weight, misery, useful impairment, and psychological well being service utilisation (Allen et al., 2013; Stice et al., 2013). Regardless of this, most individuals with an consuming dysfunction don’t obtain remedy (Swanson et al., 2011), making prevention a public well being precedence. To do that, we’d like evidence-based prevention programmes which might forestall the onset of consuming dysfunction signs earlier than remedy is required.

The Physique Venture is a prevention programme which goals to cut back the pursuit of the skinny ideally suited amongst people who find themselves at a excessive danger of growing an consuming dysfunction. The skinny ideally suited refers back to the need to own a skinny physique sort (Ralph-Nearman & Filik, 2020), the pursuit of which has been discovered to foretell the longer term onset of BN, BED, and PD (Stice et al., 2017). Nonetheless, analysis has not but established whether or not the Physique Venture can forestall the onset of various kinds of consuming issues, with proof suggesting that it may not be efficient in stopping AN onset (Stice et al., 2023). Subsequently, D’Adamo and colleagues (2023) mixed information from three randomised managed trials (RCTs) to evaluate whether or not peer-led variations of the Physique Venture had been capable of forestall the onset of those 4 various kinds of consuming issues.

The Body Project is a prevention program which has been found to reduce eating disorder onset among various populations, including both heterosexual and homosexual men and women.

The authors mixed information from three earlier research (Ghaderi et al., 2020; Stice et al., 2008, 2020). Every of those research was an RCT evaluating the Physique Venture (n = 339 members) to a management situation (n = 753 members). Research had been carried out within the USA (Stice et al., 2008, 2020) and Sweden (Ghaderi et al., 2020).


Research recruited both feminine highschool and/or faculty college students utilizing a spread of strategies (e.g., flyers, on-line ads). Individuals had been included if that they had physique picture considerations and had been excluded if that they had a present consuming dysfunction (restricted to AN or BN in Stice et al., 2008, 2020 as a result of DSM-IV standards) or if that they had extreme despair, suicidality, or one other critical psychiatric situation (Ghaderi et al., 2020).

Intervention & management situations

All members had been randomised to both the Physique Venture intervention or a management situation. The Physique Venture situations consisted of weekly 1-hour classes both in-person or on-line, and had been led by both peer educators (Stice et al., 2020), the examine authors/graduate college students (Stice et al., 2008), or undergraduate college students (Ghaderi et al., 2020).

Management teams consisted of an schooling brochure (Stice et al., 2008), a documentary (Stice et al., 2020), or an expressive writing train (Ghaderi et al., 2020).

Outcomes measures

Diagnostic interviews had been carried out at baseline, post-intervention, and 6-monthly or yearly intervals for as much as 24 months (Ghaderi et al., 2020), 36-months (Stice et al., 2008), or 48-months (Stice et al., 2020). Research by Stice et al. (2008) used the semi-structured Consuming Dysfunction Diagnostic Interview to evaluate consuming dysfunction signs, and Ghaderi et al. (2020) used the Consuming Dysfunction Examination, which was carried out over the cellphone. Different outcomes had been measured, together with purging behaviours and extreme train.

Statistical strategies

Logistic regression fashions had been used to check whether or not the onset of each subthreshold and threshold consuming dysfunction signs had been decrease within the intervention in comparison with the management situations all through the follow-up durations. Separate fashions had been estimated for AN, BN, BED, and PD.


The mixed participant group (N = 1,092) was on common 19.3 years previous (vary 14-64 years). Some variations at baseline had been recognized throughout the intervention and management teams, however additional analyses supported combining in-person and digital intervention teams, and the entire management teams.

Concerning the onset of particular consuming issues, the examine discovered:

  • For Physique Venture members with out an consuming dysfunction at baseline, the onset of any consuming dysfunction throughout the follow-up interval was 10.6% (n = 36; AN = 3, BN = 10, BED = 16, PD = 7).
  • For management situation members with out an consuming dysfunction at baseline, the onset of any consuming dysfunction throughout the follow-up interval was 17.4% (n = 131; AN = 9, BN = 42, BED = 39, PD = 41).
  • Reductions in signs for these within the Physique Venture group in comparison with the management teams had been 62% (PD), 46% (BN), 25% (AN), and eight% (BED).
  • The discount within the onset of threshold or subthreshold signs of BN (OR = 0.47, p = .02) and PD (OR = 0.35, p = .009) had been discovered to be statistically important within the Physique Venture members in comparison with these within the management group. This was not the case for AN (OR = 0.56, p = .213) or BED (OR = 0.70, p = .149).
Across the three trials, 10.6% of Body Project participants went on to develop an eating disorder in comparison to 17.4% of the control groups, indicating promise in the intervention.

Throughout the three trials, 10.6% of Physique Venture members went on to develop an consuming dysfunction compared to 17.4% of the management teams, indicating promise within the intervention.


The outcomes of this examine point out that the Physique Venture will not be appropriate for all consuming dysfunction varieties. A big discount in consuming dysfunction onset was noticed for BN and PD, the place peer-led Physique Venture teams produced a 46% and 62% discount in symptom onset respectively. While this has vital prevention results, the identical reductions weren’t seen for AN and BED, which means different preventative methods could have to be thought-about for these liable to growing these consuming issues.

Whilst the Body Project was found to significantly reduce symptoms of bulimia nervosa and purging disorder, it was not found to be effective in reducing onset of anorexia nervosa or binge eating disorder.

While the Physique Venture was discovered to considerably cut back signs of bulimia nervosa and purging dysfunction, it was not discovered to be efficient in lowering onset of anorexia nervosa or binge consuming dysfunction.

Strengths and limitations

This examine has numerous strengths:

  • By combining three separate trials collectively, the exterior validity of the outcomes could also be improved as a result of a extra diversified pattern being examined inside a number of populations and settings.
  • Comply with-up occasions had been intensive, starting from 24-months to 48-months throughout the three research. Provided that the inhabitants of those research had been these with out consuming issues, enough follow-up occasions can be wanted to permit sufficient time for consuming dysfunction onset.

Nonetheless, limitations of this examine embody:

  • The mixture of separate research with completely different management teams and follow-up lengths will increase variability and will have lowered the statistical energy of this examine. Nonetheless, the truth that these research share different methodological similarities of their inhabitants, recruitment strategies, and intervention additionally imply that the results of this paper shouldn’t be discounted.
  • The usage of management teams which had been so completely different to the intervention could imply that the constructive impact of the Physique Venture could also be all the way down to non-specific remedy results, such because the interplay with friends as a part of the intervention. Future research could as an alternative think about different management situations, corresponding to wait-list management teams, to have the ability to decide the affect of the intervention with out different peer affect.
  • Solely the research by Stice et al. (2008, 2020) collected information on ethnicity, whereby 66% of the pattern had been White. This implies we’re unable to know the true variation of the mixed pattern, which was already restricted to the inclusion of solely females, which means that outcomes can’t be generalised to males or some other figuring out individuals. Analysis means that roughly 25% of these with consuming issues are male (Beat, 2023b), highlighting the significance of contemplating males in consuming dysfunction analysis.
The sample of these studies was limited to young women, who were largely White. Future research should focus on testing this intervention across gender, ethnicity, and socioeconomic class.

Implications for observe

The outcomes of the present paper point out that the Physique Venture could also be efficient for these with BN (bulimia nervosa) and PD (purging dysfunction). This is a crucial discovering, on condition that <50% of individuals with these issues obtain full restoration (Forney et al., 2021). This highlights the necessity for efficient preventative interventions to cut back the incidence of those issues and the variety of folks requiring acute remedy; nonetheless, given the amounting stress on providers to offer remedy to these in acute want (Beat, 2023c), the availability of preventative interventions to these with out signs appears unlikely. Implementation of preventative interventions in colleges and universities to focus on these in danger needs to be thought-about, alongside additional analysis carried out with extra energetic management teams, to find out whether or not the intervention stays efficient and what the particular results are.

Regardless of these promising outcomes, the truth that the Physique Venture didn’t seem efficient for AN (anorexia nervosa) and BED (binge consuming dysfunction) highlights the necessity for additional analysis to focus on transdiagnostic danger elements which predict all 4 consuming issues. Analysis signifies that the over-evaluation of weight and form and worry of weight acquire could also be predictors of all 4 consuming dysfunction varieties (Stice et al., 2021). The authors of this paper recommend growing a refined model of the Physique Venture in an try to focus on these shared danger elements which have but to be focused inside a prevention programme.

Given the homogenous pattern examined within the three research reported on this paper, extra analysis can be now wanted to check whether or not the Physique Venture is efficient throughout gender, ethnicity, and socio-economic class. That is particularly vital on condition that the prevalence of physique dissatisfaction has elevated probably the most in boys in recent times (Solmi et al., 2021), and the latest discovering that those that establish with a couple of racial group have larger prevalence of consuming dysfunction pathology in comparison with those that have a monoracial identification (learn extra in Andie’s Psychological Elf weblog right here). Analysis corresponding to this highlights the necessity for efficient preventative interventions for a spread of populations.

Research looking at preventative interventions are desperately needed, particularly in males who have seen the biggest increase in the prevalence of body dissatisfaction in recent years.

Analysis taking a look at preventative interventions are desperately wanted, significantly in males who’ve seen the most important improve within the prevalence of physique dissatisfaction in recent times.
