Abstract
BackgroundAll over the world, Indigenous populations have remarkably high rates of commercial tobacco use compared to non-Indigenous groups. The high rates of commercial tobacco use in Indigenous populations have led to a variety of health issues and lower life expectancy than the general population. The objectives of this systematic review were to investigate changes in the initiation, consumption and quit rates of commercial tobacco use as well as changes in knowledge, prevalence, community interest, and smoke-free environments in Indigenous populations. We also aimed to understand which interventions had broad reach, what the common elements that supported positive change were and how Aboriginal self-determination was reflected in program implementation.MethodsWe undertook a systematic review of peer-reviewed publications and grey literature selected from seven databases and 43 electronic sources. We included studies between 1994 and 2015 if they addressed an intervention (including provision of a health service or program, education or training programs) aimed to reduce the use of commercial tobacco use in Indigenous communities globally. Systematic cross-regional canvassing of informants in Canada and internationally with knowledge of Indigenous health and/or tobacco control provided further leads about commercial tobacco reduction interventions. We extracted data on program characteristics, study design and learnings including successes and challenges.ResultsIn the process of this review, we investigated 73 commercial tobacco control interventions in Indigenous communities globally. These interventions incorporated a myriad of activities to reduce, cease or protect Indigenous peoples from the harms of commercial tobacco use. Interventions were successful in producing positive changes in initiation, consumption and quit rates. Interventions also facilitated increases in the number of smoke-free environments, greater understandings of the harms of commercial tobacco use and a growing community interest in addressing the high rates of commercial tobacco use. Interventions were unable to produce any measured change in prevalence rates.ConclusionsThe extent of this research in Indigenous communities globally suggests a growing prioritization and readiness to address the high rates of commercial tobacco use through the use of both comprehensive and tailored interventions. A comprehensive approach that uses multiple activities, the centring of Aboriginal leadership, long term community investments, and the provision of culturally appropriate health materials and activities appear to have an important influence in producing desired change.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-2645-x) contains supplementary material, which is available to authorized users.
Highlights
All over the world, Indigenous populations have remarkably high rates of commercial tobacco use compared to non-Indigenous groups
The high rates of commercial tobacco use in Indigenous populations have led to a variety of health issues and lower life expectancy than the general population [8]
While 87 articles are included in the review, they represent a total of 73 interventions as certain interventions were the same across multiple studies
Summary
Indigenous populations have remarkably high rates of commercial tobacco use compared to non-Indigenous groups. Canada’s Federal Tobacco Strategy has used a variety of different interventions, such as educational campaigns, a quitline and regulating sales, and has seen a 6 % reduction in tobacco use nation-wide over 11 years [9]. While these interventions have positively affected the general population, Aboriginal peoples in Canada have not experienced the same reduction in commercial tobacco use [9]. These health disparities are further compounded by a history of colonialism and social disadvantage for Indigenous peoples across the world [10]
