Summary

Quit and Win contests show higher short-term quit rates than baseline, but their long-term population impact on smoking cessation is minimal. Deception levels can be high, questioning intervention validity.

Area of Science:

  • Public Health
  • Behavioral Science
  • Addiction Medicine

Background:

  • Quit and Win contests, developed in the 1980s, are population-based smoking cessation interventions used globally.
  • International contests have been held biennially since 1994, involving numerous countries.

Purpose of the Study:

  • To evaluate if Quit and Win contests yield higher long-term smoking cessation rates compared to community baseline rates.
  • To assess the population impact of these contests, considering participant engagement and overall community prevalence reduction.

Main Methods:

  • A systematic review of randomized controlled trials and controlled studies was conducted.
  • Searches included major databases (MEDLINE, EMBASE, CINAHL, PsycINFO) and specific keywords like "quit and win" and "contest*."

  • The primary outcome was smoking abstinence for at least six months, using validated rates where possible. A meta-analysis was not performed due to study heterogeneity.

    • Main Results:

    • Three of four included studies showed significantly higher quit rates (8-20%) in Quit and Win groups at 12 months.
    • However, the population impact was small, with fewer than 1 in 500 smokers quitting due to the contest.
    • High levels of deception were noted, and the effectiveness of international contests, particularly in developing countries, requires further study due to limited controlled trials.

    Conclusions:

    • Local and regional Quit and Win contests can increase smoking cessation rates above baseline.
    • The overall population impact of these contests appears limited, and deception may affect intervention validity.
    • International contests show potential, especially in developing nations, but more rigorous comparative studies are needed for definitive conclusions.
