Influence of new tobacco control policies and campaigns on Quitline call volume in Korea.

introductionWhile tobacco control policies have been adopted and enforced, and anti-smoking campaigns have been conducted, the evaluation of their impact on tobacco quitting is lacking in Korea. Therefore, the effectiveness of tobacco control policies and mass media campaigns to encourage use of the Quitline were evaluated by monitoring call volume on Quitline, which has been in operation since 2006, in Korea.

methodsTobacco control policies and mass media campaigns, from 1 January of 2007 to 31 December of 2016, were assessed from the review of government documents and the history of law and regulation changes. The corresponding period incoming call volumes of the Quitline were assesed. The average monthly call volume, when policies and anti-smoking advertising were implemented, was compared with that of the whole year or baseline years (2007 and 2008).

resultsPeak call volume occurred in 2010 when the Quitline was directly promoted on television. The call volume in the month the TV campaign aired was 5.5 times higher than the average monthly call volume in the year 2010. A relatively gradual rise in call volume was found from 2013 to 2016 when the tobacco control policies and campaigns, such as Quitline number included on cigarette packs, a fear-oriented anti-tobacco campaign on mass media, and a tax increase on tobacco was implemented, were introduced sequentially. In that period, the average monthly call volume was about five times higher than in 2007 and 2008.

conclusionsContinuous efforts to contribute to tobacco control policies and campaigns by the promotion of the Quitline is a most effective approach to raise quitting attempts. Based on the Korean experience, Quitline data may be useful for assessing the impact of tobacco control policies and campaigns in Asian Pacific countries.
