Sunless and Indoor Tanning Among U.S. Non-Hispanic White Women Ages 18-49 Years.

The use of indoor UV tanning devices (also known as "indoor tanning") has declined in recent years. Less is known about use of dihydroxyacetone-containing products used for tanning (also known as "sunless tanning"). We analyzed data from the 2015 National Health Interview Survey. Analysis was limited to non-Hispanic White women ages 18-49 years. We estimated the proportion of women reporting spray tanning, self-applied lotion tanning, and indoor tanning and used weighted multivariable logistic regression models to examine the relationships between socio-demographic characteristics, skin cancer risk factors, and other cancer risk factors with sunless and indoor tanning. Overall, 17.7% of women reported sunless tanning. Lotion tanning was more common (15.3%) than spray tanning (6.8%), while 12.0% of women engaged in indoor tanning. Among sunless tanners, 23.7% also engaged in indoor tanning. Younger age, ever having a skin exam, skin reactions to the sun, binge drinking, and being at a healthy weight were associated with sunless tanning. While sunless tanning may be less harmful for skin cancer risk than indoor tanning, the frequency with which the two behaviors co-occur suggests that efforts to address societal pressures for women to alter their skin color may have important public health benefits.

Menthol Cigarette Smoking Trends among United States Adults, 2003-2019.

BACKGROUND: Smoking is declining, except among current menthol cigarette smokers. This study examines menthol cigarette smoking in the United States. METHODS: Cross-sectional data from 35,279 self-respondent current adult smokers who selected menthol cigarettes as their usual type, across the 2003, 2006-2007, 2010-2011, 2014-2015, and 2018-2019 waves of the nationally-representative Tobacco Use Supplement to the Current Population Survey, were analyzed in SAS/SUDAAN. Menthol cigarette smoking among current smokers was assessed by sex, age, race/ethnicity, employment, geography, and educational attainment. Linear contrasts were used to assess trends. RESULTS: Overall cigarette smoking (12.6% in 2018-2019 from 17.3% in 2003) and menthol cigarette smoking (4.0% in 2018-2019 from 4.7% in 2003) in the population decreased in 2018-2019 from 2003 (both P < 0.001). Using predicted marginals, adjusted by demographics, menthol smoking among current smokers increased to 33.8% in 2018-2019 from 27.9% in 2003 (P < 0.001). Among current smoking adults, increases in menthol smoking were observed among non-Hispanic Black persons (76.8% in 2018-2019 from 73.0% in 2003), young adults (37.7% in 2018-2019 from 31.7% in 2003), and women (39.6% in 2018-2019 from 32.1% in 2003). CONCLUSIONS: Smoking and menthol smoking in the population has decreased, yet menthol smoking among current smokers increased from 2003 to 2018-2019. Young adult, female, and non-Hispanic Black current smokers were more likely to use menthol cigarettes than their counterparts; these differences have persisted. IMPACT: Increased menthol smoking among current smokers, notably young adults, women, and non-Hispanic Black individuals, highlights the need for targeted tobacco control interventions for these health disparity populations.

Small-Area Estimation of Smoke-Free Workplace Policies and Home Rules in US Counties.

INTRODUCTION: The workplace and home are sources of exposure to secondhand smoke, a serious health hazard for nonsmoking adults and children. Smoke-free workplace policies and home rules protect nonsmoking individuals from secondhand smoke and help individuals who smoke to quit smoking. However, estimated population coverages of smoke-free workplace policies and home rules are not typically available at small geographic levels such as counties. Model-based small-area estimation techniques are needed to produce such estimates. METHODS: Self-reported smoke-free workplace policies and home rules data came from the 2014-2015 Tobacco Use Supplement to the Current Population Survey. County-level design-based estimates of the two measures were computed and linked to county-level relevant covariates obtained from external sources. Hierarchical Bayesian models were then built and implemented through Markov Chain Monte Carlo methods. RESULTS: Model-based estimates of smoke-free workplace policies and home rules were produced for 3134 (of 3143) US counties. In 2014-2015, nearly 80% of US adult workers were covered by smoke-free workplace policies, and more than 85% of US adults were covered by smoke-free home rules. We found large variations within and between states in the coverage of smoke-free workplace policies and home rules. CONCLUSIONS: The small-area modeling approach efficiently reduced the variability that was attributable to small sample size in the direct estimates for counties with data and predicted estimates for counties without data by borrowing strength from covariates and other counties with similar profiles. The county-level modeled estimates can serve as a useful resource for tobacco control research and intervention. IMPLICATIONS: Detailed county- and state-level estimates of smoke-free workplace policies and home rules can help identify coverage disparities and differential impact of smoke-free legislation and related social norms. Moreover, this estimation framework can be useful for modeling different tobacco control variables and applied elsewhere, for example, to other behavioral, policy, or health related topics.

Prevalence of Sun Protection Use and Sunburn and Association of Demographic and Behaviorial Characteristics With Sunburn Among US Adults.

Importance: Monitoring sun protection and sunburn over time at the population level can provide valuable information about progress toward skin cancer prevention goals and inform future intervention efforts. Objective: To examine the prevalence of sun protection use (shade, sunscreen, and clothing) and sunburn and the association between sunburn and individual characteristics and health behaviors in the US population. Design, Setting, and Participants: In this cross-sectional study using a nationally representative sample of 31 162 US adults from the 2015 National Health Interview Survey-Cancer Control Supplement, household interviews of civilian, noninstitutionalized US adults were conducted throughout 2015 in person and completed on the telephone when necessary. Data analysis was performed from August 16, 2016, to September 6, 2017. Main Outcomes and Measures: The prevalence of sunburn and use of sun protection and their association with demographic characteristics, sun sensitivity, and health-related behaviors and conditions using multivariable logistic regression modeling. Results: A total of 31 162 respondents (mean [SD] age, 47.0 [0.36] years; 13 932 male [44.7%] and 17 230 female [55.3%]) were included in the analyses, with 34.2% experiencing sunburn in 2015. Sunburn prevalence was higher among younger age groups (51.2% in adults 18-29 years old; 95% CI, 48.8%-53.7%), non-Hispanic white individuals (42.5%; 95% CI, 41.2%-43.9%), and those with sun-sensitive skin (50.2%). However, sunburn was also prevalent among black (13.2%; 95% CI, 11.6%-15.1%) and Hispanic (29.7%; 95% CI, 27.6%-31.9%) individuals, demographic groups that are often considered to be at low risk of skin cancer. The most frequent sun protection behaviors were staying in the shade (37.1%; 95% CI, 36.3%-38.0%) and using sunscreen (31.5%; 95% CI, 30.7%-32.3%) followed by wearing long clothing to the ankles (28.4%; 95% CI, 27.6-29.1). Sun avoidance behaviors (seeking shade and not going in the sun) were significantly (39.5% vs 35.1%; P < .001) associated with a lower prevalence of sunburn. Those who used self-applied sunless tanning products (45.0% of users vs 36.1% of nonusers; P < .001), those who engaged in aerobic activity (37.9% of aerobic exercisers vs 32.8% of non-aerobic exercisers; P < .001), binge drinkers (45.1% of binge drinkers vs 35.0% of non-binge drinkers; P < .001), and overweight or obese individuals (37.9% of overweight or obese individuals vs 34.4% of non-overweight or obese individuals; P < .001) were more likely to experience sunburn compared with the respective comparison groups. Conclusions and Relevance: Sun sensitivity was significantly associated with a higher sunburn prevalence, independent of race/ethnicity, suggesting a need to consider sun sensitivity when identifying target demographic groups for sun safety interventions. Efforts to improve vigilance and consistency with use of sun protection are needed. In addition, those who engage in physical activity, use sunless tanners, or use sunscreen for tanning purposes may require additional intervention strategies to address the unique barriers they face in staying adequately protected.

Skin cancer interventions across the cancer control continuum: A review of experimental evidence (1/1/2000-6/30/2015) and future research directions.

While the general efficacy of skin cancer interventions have been reviewed, employing the cancer control continuum would be useful to identify research gaps at specific cancer control points. We characterized the intervention evidence base for specific behavioral targets (e.g., tanning, sun protection, screening) and clinically related targets (e.g., sunburn, skin exams, cancers) at each point in the cancer control continuum. The review included articles published from 1/1/2000-6/30/15 that had an experimental design and targeted behavioral intervention in skin cancer (e.g., specific behaviors or clinically related targets). The search yielded 86 articles, including seven dissemination studies. Of the 79 non-dissemination studies, 57 exclusively targeted primary prevention behaviors, five exclusively targeted screening, 10 targeted both detection and prevention, and eight addressed cancer survivorship. Among prevention studies (n=67), 29 (43%) targeted children and 38 (57%) targeted adults. Of the 15 screening studies, nine targeted high-risk groups (e.g., men aged ≥50 years) and six targeted the general population. Although research has focused on skin cancer prevention, empirically validated interventions are still needed for youth engaged in indoor tanning and for behavioral interventions to pursue change in clinically relevant targets. Research must also address detection among those at highest risk for skin cancer, amelioration of emotional distress attendant to diagnosis and treatment, and survivorship concerns. We discuss essential qualities and opportunities for intervention development and translational research to inform the field.

Association of Cigarette, Cigar, and Pipe Use With Mortality Risk in the US Population.

Importance: Tobacco products have changed in recent years. Contemporary mortality risk estimates of combustible tobacco product use are needed. Objective: To investigate the mortality risks associated with current and former use of cigars, pipes, and cigarettes. Design, Setting, and Participants: The National Longitudinal Mortality Study is a longitudinal population-based, nationally representative health survey with mortality follow-up that includes demographic and other information from the Current Population Survey, tobacco product use information from the Tobacco Use Supplement, and mortality data from the National Death Index. In this study, participants provided tobacco use information at baseline in surveys starting from 1985 and were followed for mortality through the end of 2011. The study includes 357 420 participants who reported exclusively using cigar, pipes, or cigarettes or reported never using any type of tobacco product. Exposures: Current or former exclusive use of any cigar (little cigar, cigarillos, large cigar), traditional pipe, or cigarette and never tobacco use. Information on current daily and nondaily use was also collected. Estimates adjusted for age, sex, race/ethnicity, education, and survey year. Main Outcomes and Measures: All-cause and cause-specific mortality as identified as the primary cause of death from death certificate information. Results: Of the 357 420 persons included in the analysis, the majority of current and former cigar and pipe smokers were male (79.3%-98.0%), and smokers were more evenly divided by sex (46% of current daily smokers were male). There were 51 150 recorded deaths during follow-up. Exclusive current cigarette smokers (hazard ratio [HR], 1.98; 95% CI, 1.93-2.02) and exclusive current cigar smokers (HR, 1.20; 95% CI, 1.03-1.38) had higher all-cause mortality risks than never tobacco users. Exclusive current cigarette smokers (HR, 4.06; 95% CI, 3.84-4.29), exclusive current cigar smokers (HR, 1.61; 95% CI, 1.11-2.32), and exclusive current pipe smokers (HR, 1.58; 95% CI, 1.05-2.38) had an elevated risk of dying from a tobacco-related cancer (including bladder, esophagus, larynx, lung, oral cavity, and pancreas). Among current nondaily cigarette users, statistically significant associations were observed with deaths from lung cancer (HR, 6.24; 95% CI, 5.17-7.54), oral cancer (HR, 4.62; 95% CI, 1.84-11.58), circulatory death (HR, 1.43; 95% CI, 1.30-1.57), cardiovascular death (HR, 1.24; 95% CI, 1.11-1.39), cerebrovascular death (stroke) (HR, 1.39; 95% CI, 1.12-1.74), and chronic obstructive pulmonary disease (HR, 7.66; 95% CI, 6.09-9.64) as well as for daily smokers. Conclusions and Relevance: This study provides further evidence that exclusive use of cigar, pipes, and cigarettes each confers significant mortality risks.

State-Specific Prevalence of Tobacco Product Use Among Adults - United States, 2014-2015.

Despite recent declines in cigarette smoking prevalence, the tobacco product landscape has shifted to include emerging tobacco products* (1,2). Previous research has documented adult use of smokeless tobacco and cigarettes by state (3); however, state-specific data on other tobacco products are limited. To assess tobacco product use in the 50 U.S. states and the District of Columbia (DC), CDC and the National Cancer Institute analyzed self-reported use of six tobacco product types: cigarettes, cigars, regular pipes, water pipes, electronic cigarettes (e-cigarettes), and smokeless tobacco products among adults aged ≥18 years using data from the 2014-2015 Tobacco Use Supplement to the Current Population Survey (TUS-CPS). Prevalence of ever-use of any tobacco product ranged from 27.0% (Utah) to 55.4% (Wyoming). Current (every day or some days) use of any tobacco product ranged from 10.2% (California) to 27.7% (Wyoming). Cigarettes were the most common currently used tobacco product in all states and DC. Among current cigarette smokers, the proportion who currently used one or more other tobacco products ranged from 11.5% (Delaware) to 32.3% (Oregon). Differences in tobacco product use across states underscore the importance of implementing proven population-level strategies to reduce tobacco use and expanding these strategies to cover all forms of tobacco marketed in the United States. Such strategies could include comprehensive smoke-free policies, tobacco product price increases, anti-tobacco mass media campaigns, and barrier-free access to clinical smoking cessation resources (1,4).

Skin cancer interventions across the cancer control continuum: Review of technology, environment, and theory.

The National Cancer Institute's Skin Cancer Intervention across the Cancer Control Continuum model was developed to summarize research and identify gaps concerning skin cancer interventions. We conducted a mapping review to characterize whether behavioral interventions addressing skin cancer prevention and control from 2000 to 2015 included (1) technology, (2) environmental manipulations (policy and/or built environment), and (3) a theoretical basis. We included 86 studies with a randomized controlled or quasi-experimental design that targeted behavioral intervention in skin cancer for children and/or adults; seven of these were dissemination or implementation studies. Of the interventions described in the remaining 79 articles, 57 promoted only prevention behaviors (e.g., ultraviolet radiation protection), five promoted only detection (e.g., skin examinations), 10 promoted both prevention and detection, and seven focused on survivorship. Of the 79 non-dissemination studies, two-thirds used some type of technology (n=52; 65.8%). Technology specific to skin cancer was infrequently used: UVR photography was used in 15.2% of studies (n=12), reflectance spectroscopy was used in 12.7% (n=10), and dermatoscopes (n=1) and dosimeters (n=2) were each used in less than 3%. Ten studies (12.7%) targeted the built environment. Fifty-two (65.8%) of the studies included theory-based interventions. The most common theories were Social Cognitive Theory (n=20; 25.3%), Health Belief Model (n=17; 21.5%), and the Theory of Planned Behavior/Reasoned Action (n=12; 15.2%). Results suggest that skin cancer specific technology and environmental manipulations are underutilized in skin cancer behavioral interventions. We discuss implications of these results for researchers developing skin cancer behavioral interventions.

Changes in Self-Reported Smokefree Workplace Policy Coverage Among Employed Adults-United States, 2003 and 2010-2011.

Introduction: The workplace is a major source of exposure to secondhand smoke from combustible tobacco products. Smokefree workplace policies protect nonsmoking workers from secondhand smoke and help workers who smoke quit. This study examined changes in self-reported smokefree workplace policy coverage among U.S. workers from 2003 to 2010-2011. Methods: Data came from the 2003 (n = 74,728) and 2010-2011 (n = 70,749) waves of the Tobacco Use Supplement to the Current Population Survey. Among employed adults working indoors, a smokefree workplace policy was defined as a self-reported policy at the respondent's workplace that did not allow smoking in work areas and public/common areas. Descriptive statistics were used to assess smokefree workplace policy coverage at two timepoints overall, by occupation, and by state. Results: The proportion of U.S. workers covered by smokefree workplace policies increased from 77.7% in 2003 to 82.8% in 2010-2011 (p < .00001). The proportion of workers reporting smokefree workplace policy coverage increased in 21 states (p < .001) and decreased in two states (p < .001) over this period. In 2010-2011, by occupation, this proportion ranged from 74.3% for blue collar workers to 84.9% for white collar workers; by state, it ranged from 63.3% in Nevada to 92.6% in Montana. Conclusions: From 2003 to 2010-2011, self-reported smokefree workplace policy coverage among indoor adult workers increased nationally, and occupational coverage disparities narrowed. However, coverage remained unchanged in half of states, and disparities persisted across occupations and states. Accelerated efforts are warranted to ensure that all workers are protected by smokefree workplace policies. Implications: This study assessed changes in the proportion of indoor workers reporting being covered by smokefree workplace policies from 2003 to 2010-2011 overall and by occupation and by state, using data from the Tobacco Use Supplement to the Current Population Survey. The findings indicate that smokefree workplace policy coverage among U.S. indoor workers has increased nationally, with occupational coverage disparities narrowing. However, coverage remained unchanged in half of states, and disparities persisted across occupations and states. Accelerated efforts are warranted to ensure that all workers are protected by smokefree workplace policies.

Tobacco control in California compared with the rest of the USA: trends in adult per capita cigarette consumption.

BACKGROUND: In the 1990s, California led the USA in state-level tobacco control strategies. However, after 2000, California lost ground on cigarette taxes, although it maintained higher levels of smoke-free homes among smokers. METHODS: Trends in per capita cigarette consumption were assessed through taxed sales data and from self-report in repeated national cross-sectional surveys. Linear regressions identified changes in trends after year 2000 separately for California and the rest of the USA. Using data from each state, a linear regression tested the association between different tobacco control strategies and per capita consumption. Change in self-reported per capita consumption was partitioned into contributions associated with initiation, quitting and reduction in cigarette consumption level. RESULTS: Both taxed cigarette sales and per capita consumption declined rapidly in the USA from 1985 to 2015. Declines were particularly fast in California before 2000 but slowed thereafter. In 2014, per capita consumption in California was 29.4 packs/adult/year, but 90% higher in the rest of the USA. Modelling state-level data, every $1 increase in cigarette taxes reduced consumption by 4.8 (95% CI 2.9 to 6.8) packs/adult/year. Every 5% increase in the proportion of smokers with smoke-free homes reduced consumption by 8.0 (95% CI 7.0 to 8.9) packs/adult/year. The different patterns in California and the rest of the USA are at least partially explained by these two variables. The slow down in per capita consumption in California can be attributed to changes in initiation, quitting and especially smokers reducing their consumption level. CONCLUSIONS: Tobacco control strategies need to be continually updated to maintain momentum towards a smoke-free society.

Research on Skin Cancer-Related Behaviors and Outcomes in the NIH Grant Portfolio, 2000-2014: Skin Cancer Intervention Across the Cancer Control Continuum (SCI-3C).

Importance: The Surgeon General's Call to Action to Prevent Skin Cancer broadly identified research gaps, but specific objectives are needed to further behavioral intervention research. Objective: To review National Institute of Health (NIH) grants targeting skin cancer-related behaviors and relevant outcomes. Design, Setting, and Participants: A portfolio analysis of the title, abstract, specific aims, and research plans of identified grant applications from 2000 to 2014 targeting skin cancer-related behaviors or testing behavioral intervention effects on cancer-relevant outcomes along the cancer continuum. Main Outcomes and Measures: Funding trends were compared along the cancer control continuum, with respect to investigator demographics and use of theory, technology, policy, and changes to environmental surroundings (built environment). Results: A total of 112 submitted applications met inclusion criteria; of these, 40 (35.7%) were funded, and 31 of the 40 were interventions. Comparing the 40 funded grants with the 72 unfunded grants, the overall success rates did not differ significantly between male (33.3%) and female (37.3%) investigators, nor did the frequency of R01 awards (36.7% and 28.1%, respectively). Among intervention awards, most (24 of 31) addressed prevention. Fewer awards targeted detection alone or in conjunction with prevention (3) or cancer survivorship (4), and no grant addressed emotional sequelae or adherence behavior related to diagnosis or treatment. Fewer than half of funded grants aimed for clinically related targets (eg, sunburn reduction). Use of theory and technology occurred in more than 75% of grants. However, the full capability of proposed technology was infrequently used, and rarely did constructs of the proposed behavior change theory clearly and comprehensively drive the intervention approach. Policy or environmental manipulation was present in all dissemination grants but was rarely used elsewhere, and 19.4% included policy implementation and 25.8% proposed changes in built environment. Conclusions and Relevance: Grant success rate in skin cancer-related behavioral science compares favorably to the overall NIH grant success rate (approximately 18%), and the success rate of male and female investigators was not statistically different. However, gaps exist in behavioral research addressing all points of the skin cancer control continuum, measuring interventions that hit clinically related targets, and leveraging technology, theory, and environmental manipulation to optimize intervention approach.

E-cigarette use and smoking reduction or cessation in the 2010/2011 TUS-CPS longitudinal cohort.

BACKGROUND: Electronic cigarettes (e-cigarettes) are heavily marketed and widely perceived as helpful for quitting or reducing smoking intensity. We test whether ever-use of e-cigarettes among early adopters was associated with: 1) increased cigarette smoking cessation; and 2) reduced cigarette consumption. METHODS: A representative cohort of U.S. smokers (N = 2454) from the 2010 Tobacco Use Supplement to the Current Population Survey (TUS-CPS) was re-interviewed 1 year later. Outcomes were smoking cessation for 30+ days and change in cigarette consumption at follow-up. E-cigarettes use was categorized as for cessation purposes or for another reason. Multivariate regression was used to adjust for demographics and baseline cigarette dependence level. RESULTS: In 2011, an estimated 12 % of adult U.S. smokers had ever used e-cigarettes, and 41 % of these reported use to help quit smoking. Smokers who had used e-cigarettes for cessation were less likely to be quit for 30+ days at follow-up, compared to never-users who tried to quit (11.1 % vs 21.6 %; ORadj = 0.44, 95 % CI = 0.2-0.8). Among heavier smokers at baseline (15+ cigarettes per day (CPD)), ever-use of e-cigarettes was not associated with change in smoking consumption. Lighter smokers (<15 CPD) who had ever used e-cigarettes for quitting had stable consumption, while increased consumption was observed among all other lighter smokers, although this difference was not statistically significant. CONCLUSIONS: Among early adopters, ever-use of first generation e-cigarettes to aid quitting cigarette smoking was not associated with improved cessation or with reduced consumption, even among heavier smokers.

National and state prevalence of smoke-free rules in homes with and without children and smokers: Two decades of progress.

OBJECTIVE: The home is the primary source of secondhand smoke (SHS) exposure for children. We assessed national and state progress in smoke-free home (SFH) rule adoption in homes with and without children and adult smokers. METHODS: Data came from the 1992-1993 and 2010-2011 Tobacco Use Supplements to the Current Population Survey, a U.S. national probability household survey. Households were defined as having a SFH rule if all household respondents aged ≥18 indicated no one was allowed to smoke inside the home at any time. Households with children were those with occupants aged <18. Smokers were those who smoked ≥100 lifetime cigarettes and now smoked "everyday" or "some days". RESULTS: From 1992-1993 to 2010-2011, SFH rule prevalence increased from 43.0% to 83.0% (p<.05). Among households with children, SFH rules increased overall (44.9% to 88.6%), in households without smokers (59.7% to 95.0%), and households with ≥1 smokers (9.7% to 61.0%) (p<.05). Among households without children, SFH rules increased overall (40.8% to 81.1%), in households without smokers (53.4% to 90.1%), and households with ≥1 smokers (6.3% to 40.9%) (p<.05). Prevalence increased in all states, irrespective of smoker or child occupancy (p<.05). In 2010-2011, among homes with smokers and children, SFH rule prevalence ranged from 36.5% (West Virginia) to 86.8% (California). CONCLUSIONS: Considerable progress has been made adopting SFH rules, but many U.S. children continue to be exposed to SHS because their homes are not smoke-free. Further efforts to promote adoption of SFH rules are essential to protect all children from this health risk.

A comparison of alternative methods for measuring cigarette prices.

BACKGROUND: Government agencies, public health organisations and tobacco control researchers rely on accurate estimates of cigarette prices for a variety of purposes. Since the 1950s, the Tax Burden on Tobacco (TBOT) has served as the most widely used source of this price data despite its limitations. PURPOSE: This paper compares the prices and collection methods of the TBOT retail-based data and the 2003 and 2006/2007 waves of the population-based Tobacco Use Supplement to the Current Population Survey (TUS-CPS). METHODS: From the TUS-CPS, we constructed multiple state-level measures of cigarette prices, including weighted average prices per pack (based on average prices for single-pack purchases and average prices for carton purchases) and compared these with the weighted average price data reported in the TBOT. We also constructed several measures of tax avoidance from the TUS-CPS self-reported data. RESULTS: For the 2003 wave, the average TUS-CPS price was 71 cents per pack less than the average TBOT price; for the 2006/2007 wave, the difference was 47 cents. TUS-CPS and TBOT prices were also significantly different at the state level. However, these differences varied widely by state due to tax avoidance opportunities, such as cross-border purchasing. CONCLUSIONS: The TUS-CPS can be used to construct valid measures of cigarette prices. Unlike the TBOT, the TUS-CPS captures the effect of price-reducing marketing strategies, as well as tax avoidance practices and non-traditional types of purchasing. Thus, self-reported data like TUS-CPS appear to have advantages over TBOT in estimating the 'real' price that smokers face.

The association between demographic and behavioral characteristics and sunburn among U.S. adults - National Health Interview Survey, 2010.

OBJECTIVE: To examine the association between demographic and behavioral characteristics and sunburn among U.S. adults. METHOD: We used 2010 National Health Interview Survey data (N=24,970) to conduct multivariable logistic regressions examining associations with having 1 or more sunburns in the past year and having 4 or more sunburns in the past year. RESULTS: Overall, 37.1% of adults experienced sunburn in the past year. The adjusted prevalence of sunburn was particularly common among adults aged 18-29years (52.0%), those who repeatedly burn or freckle after 2weeks in the sun (45.9%), whites (44.3%), indoor tanners (44.1%), those with a family history of melanoma (43.9%), and those who are US-born (39.5%). Physical activity, alcohol consumption, and overweight/obesity were positively associated with sunburn (all P<0.001); sun protection behaviors were not significantly associated with sunburn (P=0.35). Among those who were sunburned in the past year, 12.1% experienced 4 or more sunburns. CONCLUSION: Sunburn is common, particularly among younger adults, those with a more sun-sensitive skin type, whites, those with a family history of melanoma, the highly physically active, and indoor tanners. Efforts are needed to facilitate sun-safety during outdoor recreation, improve the consistency of sun protection practices, and prevent sunburn, particularly among these subgroups.

Reliability of adult self-reported smoking history: data from the tobacco use supplement to the current population survey 2002-2003 cohort.

INTRODUCTION: This study examined the reliability of self-reported smoking history measures. The key measures of interest were time since completely quitting smoking among former smokers; age at which fairly regular smoking was initiated among former and current smokers; the number of cigarettes smoked per day and the number of years of daily smoking among former smokers; and never smoking. Another goal was to examine sociodemographic factors and interview method as potential predictors of the odds of strict agreement in responses. METHODS: Data from the 2002-2003 Tobacco Use Supplement to the Current Population Survey were examined. Descriptive analysis was performed to detect discrepant data patterns, and intraclass and Pearson correlations and kappa coefficients were used to assess reporting consistency over the 12-month interval. Multiple logistic regression models with replicate weights were built and fitted to identify factors influencing the logit of agreement for each measure of interest. RESULTS: All measures revealed at least moderate levels of overall agreement. However, upon closer examination, a few measures also showed some considerable differences in absolute value. The highest percentage of these differences was observed for former smokers' reports of the number of years smoking every day. CONCLUSIONS: Overall, the data suggest that self-reported smoking history characteristics are reliable. The logit of agreement over a 12-month period is shown to depend on a few sociodemographic characteristics as well as their interactions with each other and with interview method.

Prevalence of sunburn, sun protection, and indoor tanning behaviors among Americans: review from national surveys and case studies of 3 states.

BACKGROUND: Exposure to ultraviolet radiation (from solar and nonsolar sources) is a risk factor for skin cancer. OBJECTIVE: We sought to summarize recent estimates on sunburns, sun-protection behaviors, and indoor tanning available from national and selected statewide behavioral surveys. METHODS: Estimates of the prevalence of sunburn, sun-protection behaviors, and indoor tanning by US adults, adolescents, and children collected in national surveys in 1992, 2004 to 2005, and 2007 to 2009 were identified and extracted from searches of computerized databases (ie, MEDLINE and PsychINFO), reference lists, and survey World Wide Web sites. Sunburn estimates from 3 state Behavioral Risk Factors Surveillance Systems were also analyzed. RESULTS: Latest published estimates (2005) showed that 34.4% of US adults were sunburned in the past year. Incidence of sunburns was highest among men, non-Hispanic whites, young adults, and high-income groups in national surveys. About 3 in 10 adults routinely practiced sun-protection behaviors, and women and older adults took the most precautions. Among adolescents, 69% were sunburned in the previous summer and less than 40% practiced sun protection. Approximately 60% of parents applied sunscreen and a quarter used shade to protect children. Indoor tanning was prevalent among younger adults and females. LIMITATIONS: Limitations include potential recall errors and social desirability in self-report measures, and lack of current data on children. CONCLUSION: Many Americans experienced sunburns and a minority engaged in protective behaviors. Females and older adults were most vigilant about sun protection. Substantial proportions of young women and adolescents recently used indoor tanning. Future efforts should promote protective hats, clothing, and shade; motivate males and younger populations to take precautions; and convince women and adolescents to reduce indoor tanning.
