A recent systematic review by the Children’s Health Policy Centre identified two programs that successfully prevented the onset of eating disorders for teen girls — one in a general population (Education Program) and one for those at risk (Body Project). These findings suggest the following recommendations for practice and policy.
- Invest in effective prevention programs. Both successful programs addressed an established risk factor for the development of eating disorders in teen girls — body dissatisfaction. As well, both taught skills for resisting social pressures to be thin. While replication studies are needed, these evaluations suggest that it is possible to prevent new cases of eating disorders and the suffering that accompanies them. Policy-makers in BC could support offering these successful examples, while evaluating the impact in local settings. Canadian studies evaluating new approaches and programs would also be helpful.
- Make use of virtual delivery’s added benefits. Virtual delivery allows programs to reach more young people in need, particularly in rural and remote communities. And the Body Project study suggests another potentially under-recognized benefit of virtual programs: recording the sessions allows young people to catch up on any missed content. This approach can not only improve program completion but also help young people integrate information on their own time.
- Sustain prevention efforts long term. Some programs included in the review showed that selected gains diminished over time. For example, Dissonance, a precursor program to Body Project, reduced dieting at one-year but not three-year follow-up, while the Body Project reduced self-reported eating disorder symptoms at six-month but not two-year follow-up. These findings suggest that some girls may benefit from booster sessions to ensure ongoing benefits.
- Address established risk and protective factors. The programs we reviewed focused on body dissatisfaction, a risk factor often first detected in adolescence. Yet, other factors can emerge earlier in childhood, including problematic eating patterns and high anxiety levels. Therefore, it may be possible to help more children by intervening in the early years. Intervening early should include offering effective anxiety prevention programs, such as those featured in our Effective Interventions report, to reduce this condition in and of itself and as a precursor to eating disorders. Practitioners can also bolster protective factors, including assisting with parent-teen relationships to improve closeness and relationship satisfaction.
Expanding efforts to prevent eating disorders is a crucial way to reduce the number of young people experiencing these conditions and the associated mental and physical stress and distress. Beyond helping young people achieve well-being and meet their potential, effective prevention efforts should also reduce later treatment costs by reducing the numbers in need. Given the benefits for individual children and families and for society, new prevention investments are therefore strongly warranted.
