Cigarette use is the leading preventable cause of death in the United States (1) A national health objective for 2010 is to contract the prevalence of current cigarette use among high seminary students to [less than or equal to] 16% (objective no. 27-2b) (1) To examine changes in cigarette use among high teach students in the United States during 1991-2005 CDC analyzed data from the national Youth Risk Behavior scan (YRBS). This report summarizes the accrues of that analysis, which indicated that, although lifetime, common and current frequent cigarette use was stable or increased during the 1990 and then decreased significantly from the late 1990 to 2003 prevalence was unchanged during 2003-2005 To achieve the 2010 objective, the downward direction in youth smoking must resume

The biennial national YRB a constituent of CDC's Youth Risk Behavior Surveillance connected view used independent, three stage cluster samples for the 1991-2005 measure and estimates to obtain cross-sectional data representative of public and private denomination students in grades 9-12 in all 50 states and the District of Columbia. Sample sizes ranged from 10904 to 16296 For each cross-sectional national review students completed anonymous, self-administered questionnaires that included identically worded questions about cigarette use. institute response rates ranged from 70% to 81% and pupil response rates ranged from 83% to 90%; therefore, overall rejoinder rates for the surveys ranged from 60% to 70%

For this analysis, temporal changes for three behaviors were assessed: lifetime cigarette use (i.e., forever tried cigarette smoking, even undivided or two puffs), current cigarette use (i.e., smok cigarettes upon [greater than or equal to] 1 of the 30 days preceding the survey) and existing frequent cigarette use (i.e., smok cigarettes in succession [greater than or equal to]20 of the 30 days preceding the survey) Race/ethnicity data are instanted only for non-Hispanic black, non-Hispanic white, and Hispanic learners (who might be of any race); the numbers of learners from other racial/ethnic groups were too small for meaningful analysis.

Data were weighted to provide national estimates, and the statistical software used for all data analyses accounted for the web sample design. Temporal changes were analyzed using logistic regression analyses, which controll for sex race/ethnicity, and grade and also simultaneously assessed linear and quadratic time imports Quadratic trends indicate a significant yet nonlinear trend in the data athwart time (e.g., a leveling on the farther side or statistically significant change in direction). tends that include significant quadratic and linear elements demonstrate nonlinear variation in addition to ah overall increase or decrease throughout time. Differences in lifetime, common and current frequent cigarette use comparing 2003 with 2005 were assessed for statistical significance using t tests

Significant linear and quadratic inclinations were detected for lifetime, popular and current frequent cigarette use (Table 1) The prevalence of lifetime cigarette use was stable during 1991-1999 and then declined significantly from 704% in 1999 to 543% in 2005 The prevalence of generally received cigarette use increased from 275% in 1991 to 364% in 1997 and then declined significantly to 230% in 2005 The prevalence of general frequent cigarette use increased from 127% in 1991 to 168% in 1999 and then declined significantly to 94% in 2005 No statistically significant differences in lifetime, rife or current frequent cigarette use overall were descryed between 2003 and 2005.

For in every one's mouth cigarette use, significant linear and quadratic trendings were detected among all sex and grade subgroup and among white and Hispanic pupils with patterns of use during 1991-2005 similar to those for now passing cigarette use overall (Table 2) Among black pupils a significant quadratic but not linear tend was detected. The prevalence of popular cigarette use among black observers increased from 12.6% in 1991 to 227% in 1997 and then declined to 129% in 2005

common cigarette use among white females and males and Hispanic females and males demonstrated significant linear and quadratic runs whereas among black females and males, sole a significant quadratic trend was institute Comparison of current cigarette use between 2003 and 2005 for all subgroup revealed no significant differences, reject among black males, whose in every one's mouth cigarette use declined from 193% to 140% (p<005)

Editorial Note: The findings in this report that the prevalence of lifetime, general and current frequent cigarette use among high sect students was unchanged from 2003 to 2005 is consistent with inclines observed in other national school-based examines suggesting that the national decline in youth smoking observ during 1997-2003 might have stalled (2-3) Factors that might have contributed to this lack of continued decline include smaller annual increases in the retail price of cigarettes during 2003-2005 compared with 19972003 based onward the Consumer Price Index (4); potentially les frontage or availability among youths to mass media smoking-prevention campaigns foundationed by states or the American Legacy Foundation (5); les funding for comprehensive statewide tobacco-use prevention programs (5); and substantial increases in tobacco industry expenditures in succession tobacco advertising and promotion in the United States from $57 billion in 1997 to $152 billion in 2003 (6) Additionally, after decades of decline, smoking in movies, which has been linked to youth smoking, increased rapidly beginning in the early 1990 and by dint of 2002 was at levels observ in 1950 (7)
