    Abstract

    Introduction: Smoking rates are higher among Indigenous populations in most high-income countries with initiation primarily occurring in adolescence for all population groups. This review aims to identify protective and risk factors for smoking behavior among Indigenous adolescents and young adults.

    Aims and Methods: We searched Medline, Embase, and Psychinfo for all original research published between January 2006 and December 2016 that reported influences on smoking for Indigenous adolescents or young adults aged 10–24 living in Australia, New Zealand, Canada, and the United States (US). Extracted data were coded to individual, social, and environmental level categories using a modified Theory of Triadic Influence framework.

    Results:
    A total of 55 studies were included, 41 were descriptive quantitative and 14 qualitative, and 26 included Indigenous participants only. The majority were from the US (32). Frequently reported influences were at the individual and social levels such as increasing age; attitudes and knowledge; substance use; peer and family relationships; smoking norms; mental health; physical activity. At the environmental level, smoke-free spaces; second-hand smoke exposure; high community level prevalence; and social marketing campaigns were also frequently reported. Some studies referenced price, access, and traditional tobacco use. Few reported historical and cultural factors.

    Conclusions: Young Indigenous people experience similar influences to other populations such as smoking among family and friends. Greater youth smoking is related to broader community level prevalence, but few studies explore the distal or historical contributing factors such as traditional tobacco use, colonization, experiences of intergenerational trauma and discrimination, or the role of cultural connection.

    Implications: This review identified a range of factors that influence Indigenous youth smoking and contributes to an understanding of what prevention measures may be effective. Youth tobacco use occurs alongside other substance use and may also serve as an indicator of mental health. Comprehensive community-based programs that work more broadly to address the risk factors related to tobacco, including improving youth mental health, will be important for other behaviors as well. This research highlights the importance of social influence and need for ongoing denormalization of smoking. Future Indigenous led and community owned research is needed to identify likely protective cultural factors.
