We examined whether use of snus influenced cognitions in terms of smoking expectancies and smoking prototype perceptions in a direction that could promote smoking initiation, thus highlighting potential causal mechanisms between the use of snus and smoking behavior. A telephone-based longitudinal survey among Norwegian adolescents was conducted with two points of measurement during a 1-year per...

BACKGROUND AND AIMS A strong correlation exists between smoking and the use of alcohol and cannabis. This paper uses polygenic risk scores to explore the possibility of overlapping genetic factors. Those scores reflect a combined effect of selected risk alleles for smoking. METHODS Summary-level P-values were available for smoking initiation, age at onset of smoking, cigarettes per day and sm...

PURPOSE To evaluate the ability of social-psychological risk factors to predict adolescent smoking behavior. METHODS Nonsmoking adolescents (n = 4032) who participated in the 1989 and 1993 Teenage Attitudes and Practices Surveys (TAPS I) were selected for analyses. Four multivariate logistic models were used to examine (a) adolescents' smoking initiation, (b) adults' smoking initiation, (c) a...

We examine whether this also applies in economically less developed countries. METHODS Data from 7218 respondents in the 25-64 age group came from two National Health Interview Surveys conducted in 2000 and 2003 in Hungary. Independent e...
