Evaluation of School-Based Smoking-Cessation Interventions for Self-Described Adolescent Smokers

Abstract

The reformatted NOT program had a modest effect on adolescents interested in quitting. Kickin' Butts, as reformatted for this project, did not have any effect on quit rates.

Effects of Physical Activity on Teen Smoking Cessation

“…We hypothesized that youths who received N-O-TϩFIT would show significantly higher smokingcessation rates than those who received N-O-T or BI. Consistent with previous N-O-T research, 16 we also predicted that youths who received any exposure to N-O-T (whether as N-O-T or as N-O-TϩFIT) would have higher quit rates than their counterparts who received BI. N-O-T was selected as the program of use because it has been demonstrated to be effective and cost-efficient.…”

“…Beyond examination of the influence of physical activity on cessation, this study served as an opportunity to examine quit rates under numerous conditions, including analyses similar to those used by Joffe et al 16 When we analyzed data according to gender, we discovered that the N-O-TϩFIT component decreased the risk of continued smoking fourfold among boys. This finding is consistent with evidence showing that physical activity is protective against smoking initiation and increased smoking levels among youths.…”

“…Research shows that missing values in cessation trials can lead to biased estimates of outcomes that do not represent accurately the potential enrolled population. 16 Popular methods for dealing with missing data to produce complete data sets have serious drawbacks. 35 List-wise deletion can introduce biased estimates and reduced power, and simple mean replacement leads to reduction of the SE estimates.…”

“…35 List-wise deletion can introduce biased estimates and reduced power, and simple mean replacement leads to reduction of the SE estimates. Similar to procedures used by Joffe et al 16 in a 2-armed randomized trial of N-O-T, the multiple-imputation procedure described by Rubin 36 replaces missing values with a set of plausible values, eliminating uncertainty about which are the correct values to impute. The procedure introduces "error" while maintaining adequate power.…”

Prevalence of Tobacco Use Among Adolescents in North Kerala, India

“…A cross sectional study in Noida city reported an overall ever smoking prevalence of 8.8% and also observed no significant difference between the genders regarding the use of other tobacco items such as hokkah, pipe, cigars and ganja, which was more prevalent among males (Narain et al, 2011). An interventional study conducted in Baltimore and Maryland school children reported that 46% control were regular smokers and the treated school children for smoking was 49% (Joffe et al, 2009). The aims of the present study are (a) to assess prevalence of tobacco use among adolescents, (b) to ascertain the reasons for initiating tobacco use (c) to study the type of tobacco use among them.…”
