A significant health disparity exists, whereby Indigenous populations, a minority, are over-represented in the burden of smoking-related morbidity and mortality. This review highlights the paucity of evidence available to evaluate the effectiveness of smoking cessation interventions, despite the known success of these interventions in non-Indigenous populations. Due to this lack of published investigations, the external validity of this review is limited, as is the ability to draw reliable conclusions from the results. The limited but available evidence reported does indicate that smoking cessation interventions specifically targeted at Indigenous populations can produce smoking abstinence. However this evidence base is not strong with a small number of methodologically sound trials investigating these interventions. More rigorous trials are now required to assist in bridging the gap between tobacco related health disparities in Indigenous and non-Indigenous populations.
The GAINS project: outcome of smoking cessation strategies in four urban Native American clinics. Giving American Indians No-smoking Strategies.
This study was designed to assess the capability of the Doctors Helping Smokers (DHS) model to produce an increase in smoking cessation over controls within four urban Indian Health clinics. A total of 601 Native American smokers were enrolled, surveyed, and measured for cardiovascular risk factors. Of those present in treatment clinics at 1-year follow-up, 7.1% reported being abstinent vs. 4.9% in the control group. Of those who made at least one visit to the clinic during the treatment year, 9.4% self-reported being abstinent in the treatment sites vs. 3.9% in the control group (p = .04). Cotinine validated quits for all enrollees, regardless of whether they attended the clinic during the intervention, are 6.7% (intervention) and 6.8% (control). Number of quit attempts and future quit intentions were greater in the intervention group. Recommendations for future intervention efforts include earlier contact with clinicians, clinic involvement in preplanning, developing the program around the principles and realities of each site, building in more extensive components, and utilizing additional community resources.
