RESUMO
INTRODUCTION: Symptoms of nicotine dependence among adolescents occur at an early stage in smoking onset and can be present even with low exposure to cigarettes. We aim to examine the early occurrence of symptoms of nicotine dependence and how they predict later smoking behavior. METHODS: Participants were ninety-four currently smoking 9th-graders attending high school in Targu Mures, Romania. They were followed for 6 months with two assessment points: baseline, and follow-up at 6 months. We assessed the following: 1) the number of smoked cigarettes in the last 30 days, 7 days, and 24 hours using the Minnesota Smoking Index; 2) vulnerability to addiction manifested in cessation difficulties, using the 9-item version of the Hooked On Nicotine Checklist (HONC), 3) loss of autonomy using the endorsement of at least one HONC item, and 4) dependence, using the modified Fagerström Tolerance Questionnaire (mFTQ). We performed statistical analysis with SPSS version 19, using paired-sample t-tests for comparing the differences between baseline and follow-up data. We also conducted linear regression analysis to demonstrate the predictive role of the assessed variables, such as the scores of the mFTQ and the HONC in maintaining smoking and reported smoking status. RESULTS: Regression models indicated that baseline-measures for symptoms of dependence (ß=0.64, p<0.001), vulnerability to addiction (ß=0.47, p<0.001), and loss of autonomy (ß=0.34, p<0.001) regarding smoking cessation were significant predictors of smoking, explaining 41.7% of the variability of the reported increase in cigarette consumption. At follow-up at 6-months, the three variables were responsible for 14.9% for the variance in cigarette consumption (R2=0.14, F(1,92)=16.05, p<0.01). CONCLUSIONS: Nicotine dependence at baseline and at follow-up show significant differences in the control group while in the intervention group the scores remained stable. The findings suggest that participation in the Romanian version of ASPIRE was protective against progression towards nicotine addiction.
RESUMO
INTRODUCTION: Although web-based, multimedia smoking prevention programs have been tested in several high-income countries, their efficacy in Central and Eastern Europe is unknown. The aim of this trial was to assess the short-term effects of ASPIRA, among Romanian and Hungarian speaking ninth graders in Tirgu Mures, Romania. ASPIRA is the Romanian acronym for the translated and adapted version of ASPIRE, "A Smoking Prevention Interactive Experience," an evidence-based smoking prevention program originally developed to prevent tobacco use among high school students in the United States. METHODS: Sixteen high schools in Tirgu Mures, Romania were randomized to receive five weekly sessions of the ASPIRA web-based, multimedia program or to a control condition. Socio-demographic data, psychosocial characteristics, and smoking behavior were collected from students at baseline and at 6 months. A hierarchical logistic regression analysis was conducted to test the efficacy of the intervention on smoking initiation and current smoking among 1369 students. RESULTS: Never-smoker students in the intervention arm were 35% less likely to report smoking initiation 6 months after the baseline assessment (OR = 0.65, 95%CI: 0.44-0.97). Reduced smoking initiation was observed most notably among students who were exposed to at least 75% of the ASPIRA program. There was no statistically significant effect of the intervention on current tobacco use (OR = 0.80, 95%CI: 0.44-1.46). CONCLUSIONS: ASPIRA, an adapted version of the evidence-based, multimedia ASPIRE program that was originally developed and tested in the United States may decrease smoking initiation among multi-ethnic adolescents in Central and Eastern Europe. IMPLICATIONS: (1). Web-based, multimedia smoking prevention programs may be effective tools to prevent smoking initiation among multi-ethnic adolescent communities in Central and Eastern Europe. (2). The degree of exposure is critical, only high exposure to the multimedia smoking prevention program is associated with reduced smoking initiation.
