Perceived Importance of Health Concerns Among Lesbian, Gay, Bisexual, and Transgender Adults in a National, Probability-Based Phone Survey, 2017

Perceptions of the importance of health problems can drive advocacy, policy change, resource distribution, and individual behaviors. However, little is known about how lesbian, gay, bisexual, and transgender (LGBT), that is, sexual and gender minority (SGM) adults view the health problems facing SGM populations. In a 2017 national, probability-based survey of U.S. SGM adults (N = 453), we asked respondents to identify the most serious health problem facing SGM people today. Participants also rated the seriousness of five specific health problems (HIV/AIDS, suicide, hate crimes, harmful alcohol use, tobacco use). Analyses accounted for the complex sampling design and were stratified by gender identity. One quarter of U.S. SGM adults identified the most serious health problem facing SGM people to be HIV/AIDS (95% confidence interval [20.3, 31.2]). More respondents stated there were no serious LGBT health differences compared with straight/cisgender adults (4.2%, confidence interval [2.6, 5.9]) than identified tobacco use, hate crimes, chronic diseases, cancer, or suicide as the most serious. Importance ratings differed by gender and tobacco/alcohol use were perceived as less serious compared with HIV/AIDS, suicide, and hate crimes. Attention paid to HIV/AIDS by the SGM public, while important, may hinder efforts to address chronic diseases and other health issues affecting SGM people

Sulfur Mineralogy at the Mars Phoenix Landing Site

The Mars Phoenix Scout mission landed at the northernmost location (approx.68deg N) of any lander or rover on the martian surface. This paper compares the S mineralogy at the Phoenix landing site with S mineralogy of soils studied by previous Mars landers. S-bearing phases were not directly detected by the payload onboard the Phoenix spacecraft. Our objective is to derive the possible mineralogy of S-bearing phases at the Phoenix landing site based upon Phoenix measurements in combination with orbital measurements, terrestrial analog and Martian meteorite studies, and telescopic observations

Understanding Why Pictorial Cigarette Pack Warnings Increase Quit Attempts

Background: Our randomized trial found that pictorial cigarette pack warnings elicited more quit attempts than text-only warnings. Purpose: In the current study, we sought to identify psychological mechanisms that explain why pictorial cigarette pack warnings change behavior. Methods: In 2014 and 2015, we recruited 2,149 adult smokers in NC and CA, USA. We randomly assigned smokers to receive on their cigarette packs for 4 weeks either a text-only warning (one of the USA's current warnings on the side of cigarette packs) or a pictorial warning (one of the USA's proposed text warnings with pictures on the top half of the front and back of cigarette packs). Results: Pictorial warnings increased attention to, reactions to, and social interactions about cigarette pack warnings (all p < .05). However, pictorial warnings changed almost no belief or attitude measures. Mediators of the impact of pictorial warnings included increased attention, negative affect, social interactions, thinking about the warning and harms of smoking, and intentions to quit (all p < .05). Analyses also found that pictorial warnings led to greater avoidance of the warnings, which was associated with more quit attempts (p < .05). Conclusions: Pictorial warnings increased quit attempts by eliciting aversive reactions and by keeping the message vividly in smokers' minds. Contrary to predictions from several theories of health behavior, the warnings exerted little of their influence through changes in beliefs and attitudes and none of their influence through changes in risk perception. We propose the Tobacco Warnings Model based on these findings

Provider response and follow-up to parental declination of HPV vaccination

Objective: Parents often decline HPV vaccination, but little is known about how healthcare providers should promote vaccination at a later visit for secondary acceptance. We examined the associations of two factors, providers’ response to declination during the visit and follow-up after the visit, with secondary acceptance. Methods: We conducted a cross-sectional survey of US parents whose 9- to 17-year-old child had not yet completed the HPV vaccination series. Parents who declined HPV vaccination during an initial discussion with a provider (n = 447) reported whether their provider engaged in any active response during the visit (e.g., giving information, trying to change their mind) or any follow-up after the visit (e.g., scheduling another visit). We conducted multivariable logistic regression to determine whether an active response or follow-up was associated with secondary acceptance of HPV vaccination. Results: Only about one-third of parents reported an active response during the visit (35%) or follow-up after the visit (39%) following HPV vaccination declination. Parents had higher odds of secondary acceptance of HPV vaccine if they received any provider follow-up after the visit (43% vs. 20%, aOR:3.19; 95% CI:2.00:5.07). Receipt of an active provider response was not associated with secondary acceptance. More parents thought a provider should actively respond and follow-up (61% and 68% respectively), compared with those who received such a response (both p <.01). Conclusions: Providers’ follow-up after the visit may be important for promoting secondary acceptance of HPV vaccination. Parents who decline HPV vaccination often prefer to receive an active response or follow-up from a provider

Risk, Resilience, and Smoking in a National, Probability Sample of Sexual and Gender Minority Adults, 2017, USA

Background. There are well-documented inequities in smoking between sexual and gender minority (SGM; e.g., lesbian, gay, bisexual, and transgender [LGBT]) and straight and cisgender people. However, there is less information about risk for and resilience against smoking among SGM people. Such information is critical for understanding etiology and developing interventions. Aims. To conduct a within-group assessment of risks and resiliencies relating to smoking status. Method. In 2017, we conducted a cross-sectional telephone survey with a national, probability-based sample of SGM adults (N = 453). We assessed theory-informed risks (adverse childhood events, substance use–oriented social environment, mental distress, stigma, discrimination, social isolation, and identity concealment) and resiliencies (advertising skepticism, identity centrality, social support, and SGM community participation). We applied survey weights, standardized predictor variables, and fit logistic regression models predicting smoking status. We stratified by age and SGM identity. Results. Patterns of risk and resilience differ by age and identity. Effects were consistently in the same direction for all groups for participating in substance use–oriented social environments, pointing to a potential risk factor for all groups. Advertising skepticism and having people you can talk to about being LGBTQ were potential protective factors. Discussion. Intervention development should address risk and resilience that differs by SGM identity. Additionally, our findings suggest interventionists should consider theoretical frameworks beyond minority stress. Conclusion. While much of the literature has focused on the role of stress from stigma and discrimination in tobacco use, addressing social norms and bolstering protective factors may also be important in SGM-targeted interventions

Questions and concerns about HPV vaccine: A communication experiment

OBJECTIVES: We sought to identify effective responses to parents’ questions and concerns about human papillomavirus (HPV) vaccine. METHODS: In 2017–2018, we surveyed a national sample of 1196 US parents of children aged 9 to 17 years. We recorded brief videos of a pediatrician providing messages that addressed 7 HPV vaccination topics that commonly elicit questions or concerns (eg, recommended age). We randomly assigned parents to 1 of the message topics; parents then viewed 4 videos on that topic in random order and evaluated the messages. RESULTS: Parents were more confident in HPV vaccine when they were exposed to messages that addressed lack of knowledge about HPV vaccine (b = 0.13; P = .01), messages that included information about cancer prevention (b = 0.11; P < .001), messages that required a higher reading level (b = 0.02; P = .01), and messages that were longer (b = 0.03; P < .001). Parents were less confident in HPV vaccine when exposed to messages in which urgency was expressed (b = −0.06; P = .005). Analyses conducted by using HPV vaccine motivation as an outcome revealed the same pattern of findings. CONCLUSIONS: We provide research-tested messages that providers can use to address parents’ HPV vaccination questions and concerns about 7 common topics. Important principles for increasing message effectiveness are to include information on the benefits of vaccination (including cancer prevention) and avoid expressing urgency to vaccinate when addressing parents' questions or concerns. Additionally, providers may need to be prepared to have longer conversations with parents who express concerns about HPV vaccine, especially regarding safety and side effects

Cigarette pack messages about toxic chemicals: A randomised clinical trial

Background The USA can require tobacco companies to disclose information about harmful and potentially harmful chemicals in cigarette smoke, but the impact of these messages is uncertain. We sought to assess the effect of placing messages about toxic chemicals on smokers' cigarette packs. Methods Participants were 719 adult cigarette smokers from California, USA, recruited from September 2016 through March 2017. We randomly assigned smokers to receive either factual messages about chemicals in cigarette smoke and their health harms (intervention) or messages about not littering cigarette butts (control) on the side of their cigarette packs for 3 weeks. The primary trial outcome was intention to quit smoking. Results In intent-to-treat analyses, smokers whose packs had chemical messages did not have higher intentions to quit smoking at the end of the trial than those whose packs had control messages (P=0.56). Compared with control messages, chemical messages led to higher awareness of the chemicals (28% vs 15%, P<0.001) and health harms (60% vs 52%, P=0.02) featured in the messages. In addition, chemical messages led to greater negative affect, thinking about the chemicals in cigarettes and the harms of smoking, conversations about the messages and forgoing a cigarette (all P<0.05). Discussion Chemical messages on cigarette packs did not lead to higher intentions to quit among smokers in our trial. However, chemical messages informed smokers of chemicals in cigarettes and harms of smoking, which directly supports their implementation and would be critical to defending the messages against cigarette company legal challenges. Trial registration number NCT02785484

Public Understanding of Cigarette Smoke Chemicals: Longitudinal Study of US Adults and Adolescents

Introduction: The US Food and Drug Administration has increased communication efforts that aim to raise public awareness of the harmful constituents (ie, chemicals) in cigarette smoke. We sought to investigate whether the public's awareness of these chemicals has increased in light of such efforts. Methods: Participants were national probability samples of 11 322 US adults and adolescents recruited in 2014-2015 (wave 1) and 2016-2017 (wave 2). Cross-sectional telephone surveys assessed awareness of 24 cigarette smoke chemicals at both timepoints. Results: The proportion of US adults aware of cigarette smoke chemicals did not differ between waves 1 and 2 (25% and 26%, p =. 19). In contrast, awareness of chemicals among adolescents fell from 28% to 22% (p <. 001), mostly due to lower awareness of carbon monoxide, arsenic, benzene, and four other chemicals. Belief that most of the harmful chemicals in cigarette smoke come from burning the cigarette also fell from waves 1 to 2 (adults: 31% vs. 26%; adolescents: 47% vs. 41%, both ps <. 05). Participants were more likely to be aware of cigarette smoke chemicals if they had been exposed to anti-smoking campaign advertisements (p <. 05) or had previously sought chemical information (p <. 05). Cigarette smoke chemical awareness did not differ between smokers and nonsmokers. Conclusion: Awareness of cigarette smoke chemicals remains low and unchanged among adults and decreased somewhat among adolescents. The association of chemical awareness with information exposure via campaigns and information seeking behavior is promising. More concerted communication efforts may be needed to increase public awareness of cigarette smoke chemicals, which could potentially discourage smoking. Implications: Awareness of the toxic chemicals in cigarette smoke may contribute to quitting. The US Food and Drug Administration is making efforts to increase public awareness of these chemicals. Two national surveys (2014-2017) found that chemical awareness was low among adults and adolescents. Although awareness did not change among adults, awareness among adolescents dropped over time. In addition, exposure to anti-smoking campaigns and chemical information seeking behavior were associated with higher awareness of chemicals in cigarette smoke. Campaigns and other efforts may be needed to increase awareness of cigarette smoke chemicals

Using Social Networks to Supplement RDD Telephone Surveys to Oversample Hard-to-Reach Populations: A New RDD+RDS Approach

Random digit dialing (RDD) telephone sampling, although experiencing declining response rates, remains one of the most accurate and cost-effective data collection methods for generating national population-based estimates. Such methods, however, are inefficient when sampling hard-to-reach populations because the costs of recruiting sufficient sample sizes to produce reliable estimates tend to be cost prohibitive. The authors implemented a novel respondent-driven sampling (RDS) approach to oversample cigarette smokers and lesbian, gay, bisexual, and transgender (LGBT) people. The new methodology selects RDS referrals or seeds from a probability-based RDD sampling frame and treats the social networks as clusters in the weighting and analysis, thus eliminating the intricate assumptions of RDS. The authors refer to this approach as RDD+RDS. In 2016 and 2017, a telephone survey was conducted on tobacco-related topics with a national sample of 4,208 U.S. adults, as well as 756 referral-based respondents. The RDD+RDS estimates were comparable with stand-alone RDD estimates, suggesting that the addition of RDS responses from social networks improved the precision of the estimates without introducing significant bias. The authors also conducted an experiment to determine whether the number of recruits would vary on the basis of how the RDS recruitment question specified the recruitment population (closeness of relationship, time since last contact, and LGBT vs. tobacco user), and significant differences were found in the number of referrals provided on the basis of question wording. The RDD+RDS sampling approach, as an adaptation of standard RDD methodology, is a practical tool for survey methodologists that provides an efficient strategy for oversampling rare or elusive populations

Coaching and Communication Training for HPV Vaccination: A Cluster Randomized Trial

BACKGROUND AND OBJECTIVES: US health departments routinely conduct in-person quality improvement (QI) coaching to strengthen primary care clinics' vaccine delivery systems, but this intervention achieves only small, inconsistent improvements in human papillomavirus (HPV) vaccination. Thus, we sought to evaluate the effectiveness of combining QI coaching with remote provider communication training to improve impact. METHODS: With health departments in 3 states, we conducted a pragmatic 4-arm cluster randomized clinical trial with 267 primary care clinics (76% pediatrics). Clinics received in-person QI coaching, remote provider communication training, both interventions combined, or control. Using data from states' immunization information systems, we assessed HPV vaccination among 176 189 patients, ages 11 to 17, who were unvaccinated at baseline. Our primary outcome was the proportion of those, ages 11 to 12, who had initiated HPV vaccination at 12-month follow-up. RESULTS: HPV vaccine initiation was 1.5% points higher in the QI coaching arm and 3.8% points higher in the combined intervention arm than in the control arm, among patients ages 11 to 12, at 12-month follow-up (both P < .001). Improvements persisted at 18-month follow-up. The combined intervention also achieved improvements for other age groups (ages 13-17) and vaccination outcomes (series completion). Remote communication training alone did not outperform the control on any outcome. CONCLUSIONS: Combining QI coaching with remote provider communication training yielded more consistent improvements in HPV vaccination uptake than QI coaching alone. Health departments and other organizations that seek to support HPV vaccine delivery may benefit from a higher intensity, multilevel intervention approach
