The purpose of this study is to improve the estimate of number of quit attempts prior to quitting successfully. Design: We used data from 1277 participants who had made an attempt to quit smoking in the Ontario Tobacco Survey, a longitudinal survey of smokers followed every 6 months for up to 3 years beginning in 2005. We calculated the number of quit attempts prior to quitting successfully under four different sets of assumptions. Our expected best set of assumptions incorporated a life table approach accounting for the declining success rates for subsequent observed quit attempts in the cohort. Results: The estimated average number of quit attempts expected before quitting successfully ranged from 6.1 under the assumptions consistent with prior research, 19.6 using a constant rate approach, 29.6 using the method with the expected lowest bias, to 142 using an approach including previous recall history. Conclusions: Previous estimates of number of quit attempts required to quit may be underestimating the average number of attempts as these estimates excluded smokers who have greater difficulty quitting and relied on lifetime recall of number of attempts. Understanding that for many smokers it may take 30 or more quit attempts before being successful may assist with clinical expectations.

Borzekowski, Auteur ; Joanna E Cohen, Auteur Editeur : American Academy of Pediatrics Année de publication : 2013 Collection : Pediatrics - Official journal of the American Academy of Pediatrics, ISSN Borzekowski num. 132 Importance : p.e825 - e831 Langues : Anglais (eng) Catégories : [DIVERS] géographie:Afrique:Afrique subsaharienne:Nigeria [DIVERS] géographie:Amérique:Amérique latine:Brésil [DIVERS] géographie:Asie:Asie du Sud:Inde [DIVERS] géographie:Asie:Extrême-Orient:Chine [DIVERS] géographie:Asie:Proche et Moyen-Orient:Pakistan [DIVERS] géographie:Asie:Russie [DIVERS] personne:famille:enfant [TABAC] économie du tabac:marketing [TABAC] économie du tabac:marketing:publicité [TABAC] tabagisme:aspect psychologique:comportement Index. décimale : TA 8.8 Publicité Résumé : BACKGROUND: Prosmoking messages, delivered through marketing and the media, can reach very young children and influence attitudes and behaviors around smoking. This study examined the reach of tobacco marketing to 5 and 6 year olds in 6 low- and middle-income countries. METHODS: Researchers worked one-on-one with 5 and 6 year olds in Brazil, China, India, Nigeria, Pakistan, and Russia (N = 2423). The children were asked to match logos with pictures of products, including 8 logos for cigarette brands. Analyses examined, overall and by country, whether gender, age, location, household use of tobacco, and knowledge of media characters were associated with awareness of cigarette brand logos. Additional analyses considered the relationship between cigarette brand logo awareness and intentions to smoke. RESULTS: Overall, 68% of 5 and 6 year olds could identify at least 1 cigarette brand logo, ranging from 50% in Russia to 86% in China. Across countries, being slightly older and having someone in the household who used tobacco, were significantly associated with greater odds of being able to identify at least 1 cigarette brand logo. CONCLUSIONS: The majority of young children from low- and middleincome countries are familiar with cigarette brands. This study’s findings suggest that more effective measures are needed to restrict the reach of tobacco marketing.
