SD smokers make up a substantial segment of the smoking population. They are not just beginning to smoke nor trying to quit. Many have developed a long-standing pattern of nondaily smoking, smoking relatively few cigarettes on the days when they do smoke. They are not substantially younger than daily smokers, as one might expect.

AbstractThis report describes the methodology for the 2007 U.S. national field study to estimate the prevalence of alcohol-, drug-, and alcohol-and-drug-involved driving, primarily among nighttime weekend drivers, but also daytime Friday drivers. This study involved randomly stopping drivers at 300 locations across the continental United States; sites were selected through a stratified random sampling procedure. Data were collected during a 2-hour Friday daytime session at 60 locations, and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on both Friday and Saturday nights) at 240 locations. Both self-report and biological measures were taken. An objective was to obtain at least 7,500 oral fluid samples for analysis. Biological measures included breath alcohol measurements on 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents. Oral fluid and blood samples were subjected to laboratory screening and LC/MS-MS and GC/MS confirmation respectively for both alcohol and 20 categories of drugs. These data are being analyzed to develop the first national prevalence estimate of alcohol-and drug-involved driving. This first report describes the field methods used to conduct this study, including data collection procedures. Overall response rates are also presented. Two other reports will present the results of the data collection and analyses; one will focus on alcohol use prevalence estimates among drivers and compare them with previous National Roadside Surveys conducted in 1973, 1986, and 1996; the other report will provide drug use prevalence estimates among drivers. AcknowledgementsThe authors would like to acknowledge the extensive assistance we received from State and local officials in the conduct of this project. Our data collection procedures were not routine by any means and the willingness of State officials to help us identify local police agencies and the agencies' willingness to participate in the project were essential to our success.

Cost data are useful in comparing various health problems, assessing risks, setting research priorities, and selecting interventions that most efficiently reduce health burdens. Using analyses of national and state data sets, this article presents data on the frequency, costs, and quality-of-life losses associated with unintentional childhood injuries in 1996. The frequency, severity, potential for death and disability, and costs of unintentional injury make it a leading childhood health problem. Unintentional childhood injuries in 1996 resulted in an estimated $14 billion in lifetime medical spending, $1 billion in other resource costs, and $66 billion in present and future work losses. These injuries imposed quality-of-life losses equivalent to 92,400 child deaths. Since Medicaid and other government sources paid for 39% of the days children spent in hospitals due to unintentional injuries, the government has a financial interest in, and arguably a responsibility for, assuring the safety of disadvantaged children. Federal agencies, however, devote relatively few public dollars to injury prevention research and programming. Several proven child safety interventions cost less than the medical and other resource costs they save. Thus, governments, managed care companies, and third-party payers could save money by encouraging the routine use of selected child safety measures such as child safety seats, bicycle helmets, and smoke detectors. Yet, these and other proven injury prevention interventions are not universally implemented.

AbstractThis report presents the first national prevalence estimates for drug-involved driving derived from the recently completed 2007 National Roadside Survey (NRS). The NRS is a national field survey of alcohol-and drug-involved driving conducted primarily among nighttime weekend drivers, but also daytime Friday drivers. The survey involved randomly stopping drivers at 300 locations across the continental United States; sites were selected through a stratified random sampling procedure. This included data that we collected during a two-hour Friday daytime session at 60 locations and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on both Friday and Saturday) at 240 locations. Both self-report and biological measures were taken. Biological measures included breath alcohol measurements on 9,413 respondents, oral fluid from 7,719 respondents, and blood samples from 3,276 respondents. Oral fluid and blood samples were subjected to laboratory screening and LC/MS-MS and GC/MS confirmation for 75 drugs and metabolites, including illegal, prescription, and over-the-counter drugs. These data were analyzed to develop the first national prevalence estimate of alcohol-and drug-involved driving. Two prior reports on the 2007 NRS described: (1) the sampling plan and data collection methodology, summarizing the response patterns to the various stages of the multi-part survey; and (2) the prevalence estimates for alcohol-involved driving derived from the study, and comparing them with the three previous National Roadside Surveys (NRS). iii AcknowledgementsThe authors received extensive assistance from State and local officials in the conduct of this project.

ABSTRACT. Objective: The purpose of this study was to determine whether the relative risk of being involved in an alcohol-related crash has changed over the decade from 1996 to 2007, a period during which there has been little evidence of a reduction in the percentage of all fatal crashes involving alcohol. Method: We compared blood-alcohol information for the 2006 and 2007 crash cases (N = 6,863, 22.8% of them women) drawn from the U.S. Fatality Analysis Reporting System (FARS) with control blood-alcohol data from participants in the 2007 U.S. National Roadside Survey (N = 6,823). Risk estimates were computed and compared with those previously obtained from the 1996 FARS and roadside survey data. Results: Although the adult relative risk of being involved in a fatal alcohol-related crash apparently did not change from 1996 to 2007, the risk for involvement in an alcohol-related crash for underage women has increased to the point where it has become the same as that for underage men. Further, the risk that sober underage men will become involved in a fatal crash has doubled over the 1996-2007 period. Conclusions: Compared with estimates obtained from a decade earlier, young women in this study are at an increased risk of involvement in alcohol-related crashes. Similarly, underage sober drivers in this study are more at risk of involvement in a crash than they were a decade earlier. (J. Stud. Alcohol Drugs, 73, 341-350, 2012)

The present study examined the relationship between recent smoking cessation activities and sociodemographic characteristics, smoking intensity, and tobacco control policies among daily smokers in the United States. The study used the U.S. Current Population Survey 1998-1999 Tobacco Use Supplement, supplemented with information on state-level tobacco control policies. The sample was limited to individuals aged 25 years or older who were smoking daily 1 year ago. We estimated frequencies and multivariate logistic equations for making a quit attempt and remaining abstinent at least 3 months. These measures were related to demographic characteristics, smoking intensity, and tobacco control policies. Younger, higher socioeconomic status (SES), and less intense (fewer cigarettes per day) daily smokers were more likely to make quit attempts, but the likelihood of remaining abstinent for those making a quit attempt was greater for older, higher SES, and heavy daily smokers. We found evidence that cessation behaviors were related to higher cigarette prices and the presence of state-level media/comprehensive campaigns, but less clear evidence exists for an association with bans restricting workplace smoking. The results indicate that certain types of smokers are more likely to attempt to quit and to have success and that the characteristics of these smokers differ. Price policies can have an important role in helping daily smokers to quit. Further research is needed regarding the role of quantity smoked.

AbstractThis report presents the prevalence estimates for alcohol-involved driving derived from the recently completed U.S. national field survey of alcohol-and drug-involved driving (primarily of nighttime weekend drivers, but also daytime Friday drivers) and compares those estimates with the three previous National Roadside Surveys. This survey involved randomly stopping drivers at 300 locations across the 48 contiguous United States. Data were collected during 2-hour Friday daytime sessions (9:30 a.m. to 11:30 a.m. or 1:30 p.m. to 3:30 p.m.) at 60 locations and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on Fridays and Saturdays) at 240 locations. Both self-report and biological measures were taken. Biological measures included breath-alcohol measurements on 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents. A prior report described the sampling plan and data collection methodology and summarized the response patterns to the various stages of the multipart survey. A third report, based on analyses of the oral fluid and blood specimens collected, will present the first national prevalence estimate of drug-involved driving and of alcohol-plus-drug-involved driving. This report focuses on the alcohol breath-test results and how they relate to previous national surveys. It also summarizes response patterns to survey questions and to an alcohol-use-disorder-screening instrument. The data indicate a continuing trend over the past three decades of fewer alcohol-involved drivers on the Nation's roads during weekend nights.
