A report on empowerment, published by the WHO in 2006 but little known among professionals, demonstrates the proven value of this approach in public health initiatives. Involving the public in the design and implementation of health promotion initiatives increases their effectiveness, the WHO emphasizes. It also helps address inequalities, since empowerment primarily benefits those furthest removed from power and preventive care. Hence the need to adopt this approach, which is still very rarely used. To do so, it is urgent to train professionals and decision-makers in this approach.
