UNLABELLED OBJECTIVES. This study aims to assess the trend in initiation and cessation of smoking across successive birth cohorts, according to gender and education, in order to provide useful suggestion for tobacco control policy. STUDY DESIGN. The study is based on data from the "Health conditions and resort to sanitary services" survey carried out in Italy from October 2004 to September 2005...

This study was designed to determine whether the relation between parents' recency of (lifetime) marijuana use (RMU) and their adolescent children's subsequent marijuana initiation was mediated by the adolescents' expectancies regarding the consequences of usage, their anticipated severity of punishment for use, and their evaluative attitudes toward marijuana. Parents and their initially mariju...

This paper examines the relative contributions of compositional and contextual effects on the one hand, and behavioural and material factors on the other, to help explain smoking initiation. We present results from a cross-sectional, multi-level analysis linking data from pre-adolescents, their households and their neighbourhoods across Quebec, Canada. Results show a significant geographical ar...

OBJECTIVE To identify factors associated with age of smoking initiation and distinguish vulnerable periods for initiation according to those factors. METHOD Discrete time hazards analysis was used to model smoking initiation as a function of age (5-23), demographic and familial influence variables (measured at age 13), and their interactions in a cohort of 6255 youths who completed six assess...

OBJECTIVE This report examines the prevalence and common correlates of early smoking initiation among male and female school children across seven African countries. METHOD The total sample included 17,725 school children aged 13 to 15 years from nationally representative samples in seven African countries. Univariate and multivariate analyses were conducted to assess the relationship between...

Introduction: It has been well documented that resilience is a protective factor against the abuse of a variety of drugs. To date, this factor has not been examined regarding waterpipe smoking. This study aims to investigate the predictive role of resilience in tobacco use among students of the University of Medical Sciences. Materials and Methods: A cross-sectional study was conducted among a...

BACKGROUND Smoking prevalence in Italy decreased by 37% from 1980 to now. This is due to changes in smoking initiation and cessation rates and is in part attributable to the development of tobacco control policies. This work aims to estimate the age- and sex-specific smoking initiation and cessation probabilities for different time periods and to predict the future smoking prevalence in Italy, ...

OBJECTIVE To show long-term trends of smoking initiation in Great Britain including unanalysed data and assess the impact of early smoking initiation on the lung cancer mortality in later ages focusing on birth cohorts. DESIGN Reanalysis of repeated cross-sectional surveys conducted 13 times during 1965-1987. SETTING Great Britain. PARTICIPANTS Men and women aged 16 years and over in each...

PURPOSE To investigate the relationship between perceived prevalence of smoking and smoking initiation among Hong Kong primary second- to fourth-grade-students. METHODS A cohort of 2,171 students was surveyed in 2006 and again in 2008. Students who perceived ever-smoking prevalence in peers as "none" or "some" were considered as correct (reference group), whereas those who perceived it as "ha...
