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.
