Abstract
in English, French

Purpose: To evaluate and summarize evidence on the effectiveness of interventions available to public health staff regarding the protection of the public from environmental risks.

Method: This systematic review involved a comprehensive literature search, screening for relevance, quality assessment of relevant studies, data extraction and synthesis.

Results: Fourteen of 65 relevant studies were of 'moderate' or 'strong' quality. Intervention types in these 14 studies included: mass campaign, counselling, school curriculum, educational sessions, and distribution of printed materials. Short-term improvements in awareness or knowledge were observed in 13 of the 14 studies. Eight of 13 studies that examined behavioural outcomes observed short-term improvements in self-reported behavioural outcomes.

Conclusions: Positive short-term changes in health-protective awareness, knowledge and self-reported behaviour appear to be associated with relatively intensive interventions that use multiple methods and settings, and/or are delivered over multiple sessions.

Objet: Évaluer et résumer les preuves de l’efficacité des interventions dont dispose le personnel de la santé publique pour protéger la population contre les risques liés à l’environnement.

Méthode: Cette étude systématique s’est composée d’une analyse documentaire exhaustive, d’un tri des résultats en fonction de leur pertinence, d’une évaluation de la qualité des études sur la question et de l’extraction et de la synthèse des données.

Résultats: Quatorze des 65 études pertinentes étaient de qualité « moyenne » ou « élevée ». Parmi les types d’intervention recensés dans ces 14 études, on trouve les campagnes de masse, le counseling, les séances de sensibilisation et la diffusion de documents imprimés. Dans 13 des 14 études, on a observé des améliorations rapides de la prise de conscience et de la connaissance du sujet. Dans 8 des 13 études portant sur les résultats comportementaux, on a observé des améliorations rapides dans les résultats déclarés par les répondants.

Conclusions: Les changements positifs rapides (sensibilisation aux mesures de protection de la santé, connaissances et modification auto-déclarée du comportement) semblent associés aux interventions relativement intensives, qui ont recours à de multiples méthodes et milieux ambiants, et (ou) sont répétées à maintes reprises.
