OBJECTIVE Sport and scholastic factors are known to be associated with cigarette smoking in adolescence, but little is known about the causality of this association. The aim of this study was to prospectively explore the relationships of different sport and scholastic factors with smoking prevalence initiation in older adolescents from Bosnia and Herzegovina. METHODS In this 2-year prospectiv...

The consequences of starting smoking by age 18 are significant. Early smoking initiation is associated with higher tobacco dependence, increased difficulty in smoking cessation and more negative health outcomes. The purpose of this study is to examine how closely smoking initiation in a well-defined population of American Indians (AI) resembles a group of Non-Hispanic white (NHW) populations bo...

OBJECTIVES Young adults face high prevalence rates for smoking. Recent evidence suggests that many people initiate smoking during young adulthood, but little is currently known about trends in initiation rates for this age group. METHODS We examined rates of initiation to first cigarette (FC) and daily smoking (DS) during youth (5-17 years) and young adulthood (18-25 years) using nationally r...

We examined changes in the patterns of the rates of smoking initiation in the United States by gender for 1950, 1965, and 1980. Data from National Health Interview Surveys on the ages people started smoking (survey years 1970, 1978, 1979, 1980, 1987, and 1988) were used to construct age-specific rates of smoking initiation for males and females 10 to 24 years of age for 1950, 1965, and 1980. We...

From 1965 to 1990, the prevalence of cigarette smoking among US adults (aged > or = 18 years) fell steadily and substantially. Data for the 1990s suggest that the smoking initiation rate is increasing and that the decline in the prevalence of smoking may have stalled, raising the fear that the historical 25-year decline will not continue. The authors used a new dynamic forecasting model to show...

Smoking initiation is a key behaviour that determines the future health consequences of smoking in a society. There is a marked difference in smoking patterns around the world, driven by initiation rates. While a number of high-income countries have seen smoking prevalence decline markedly from peak, many low-income and middle-income countries appear to still be on an upward trend. Unlike cessa...
