Crowd-Sourced Focus Groups on Twitter: 140 Characters of Research Insight

Researchers have traditionally relied on in-person focus groups to test and obtain feedback regarding behavioral and technology-based interventions for specific disease processes. An increasing generation of engaged and connected patients turn to Twitter, a popular microblogging service, to discuss health related topics. Regularly scheduled Twitter-based chats (tweetchats) can potentially function as an additional source of input and information from a diverse, global group of engaged participants. We report the first use of a “tweetchat focus group” to explore data collection issues using this methodology. The speed at which tweetchat conversations occur, coupled with the ability to pursue multiple streams of conversation both in real time and in a delayed fashion, make tweetchat data collection particularly challenging. We discuss important considerations and preparation that should be undertaken by the researchers prior to initiating a tweetchat focus group, consider facilitation challenges and issues of confidentiality.

Electronic Cigarette Use Among High School Students and Its Association With Cigarette Use And Smoking Cessation, North Carolina Youth Tobacco Surveys, 2011 and 2013

Although adolescent cigarette use continues to decline in the United States, electronic cigarette (e-cigarette) use among adolescents has escalated rapidly. This study assessed trends and patterns of e-cigarette use and concurrent cigarette smoking and the relationships between e-cigarette use and smoking cessation intentions and behaviors among high school students in North Carolina

Consumers’ Preferences for Electronic Nicotine Delivery System Product Features: A Structured Content Analysis

To inform potential governmental regulations, we aimed to develop a list of electronic nicotine delivery system (ENDS) product features important to U.S. consumers by age and gender. We employed qualitative data methods. Participants were eligible if they had used an ENDS at least once. Groups were selected by age and gender (young adult group aged 18–25, n = 11; middle-age group aged 26–64, n = 9; and women’s group aged 26–64, n = 9). We conducted five individual older adult interviews (aged 68–80). Participants discussed important ENDS features. We conducted a structured content analysis of the group and interview responses. Of 34 participants, 68% were white and 56% were female. Participants mentioned 12 important ENDS features, including: (1) user experience; (2) social acceptability; (3) cost; (4) health risks/benefits; (5) ease of use; (6) flavors; (7) smoking cessation aid; (8) nicotine content; (9) modifiability; (10) ENDS regulation; (11) bridge between tobacco cigarettes; (12) collectability. The most frequently mentioned ENDS feature was modifiability for young adults, user experience for middle-age and older adults, and flavor for the women’s group. This study identified multiple features important to ENDS consumers. Groups differed in how they viewed various features by age and gender. These results can inform ongoing regulatory efforts

Insights into Adolescent Online Conflict through Qualitative Analysis of Online Messages

Given adolescents’ widespread use of online messaging and social media, as well as the prevalence of cyberbullying, analyzing adolescents’ online message-based communication topics and patterns is relevant to public health. To better describe conflict in adolescent online communication, this paper analyzes patterns of conflict in a dataset of adolescent online messages. We describe a qualitative methodology for analyzing these complex data, to expand understanding of adolescents’ online conversations, and to identify how best to categorize conflict within online media datasets. In this study, 14,239 messages from 20 adolescents in the Northeast United States (of which 1,911 were coded) were analyzed using thematic analysis. Several distinct kinds of conflict and responses were identified. Conflict was either direct or indirect, serious or non-serious; it most often was indirect and serious, referenced either insults or romantic contacts, and was frequently related to in-person fights. Coding relied on understanding both textual contexts and referents

Trends and Correlates of Hookah Use Among High School Students in North Carolina

OBJECTIVES Although youth cigarette smoking has declined in the United States, use of alternative tobacco products, such as hookah, has increased. This study assesses changes in prevalence of use from 2011 to 2013, and examines factors associated with current hookah use among North Carolina high school students in 2013.METHODS Data came from the North Carolina Youth Tobacco Survey in 2011 (n = 4,791) and 2013 (n = 4,092). STATA (StataCorp LLC) logistic regression survey procedures account for the complex survey design and sampling weights.RESULTS Prevalence of reported current hookah use significantly increased from 3.6% (95% CI: 2.8-4.5) in 2011 to 6.1% (95% CI: 4.9-7.5) in 2013 while reported lifetime hookah use increased from 9.8% (95% CI: 8.0-12.0) in 2011 to 12.6% (95% CI: 11.0-14.4) in 2013. Correlates of current hookah use included having a weekly disposable income over $50 (adjusted odds ratio (AOR) = 2.05, 95% CI: 1.25-3.35), currently smoking cigarettes (AOR = 4.57, 95% CI: 1.80-11.62), and living with hookah users (AOR = 6.45, 95% CI: 3.21-12.93). Participant self-reports of "liking" or positively commenting on tobacco products on social media were associated with current hookah use (AOR = 1.83, 95% CI: 1.84-4.52). Frequent exposure to online tobacco advertisements (AOR = 1.61, 95% CI: 1.13-2.28) were also associated with current hookah use.CONCLUSIONS Comprehensive product specific communication and policy interventions are needed to educate youth about the dangers of hookah use and reduce social acceptability among youth. To decrease hookah use in North Carolina, policymakers should consider restoring funding for comprehensive tobacco prevention and control programs, and equalizing tobacco tax rates for all tobacco product types

Support Among Middle School and High School Students for Smoke-free Policies, North Carolina, 2009

IntroductionIn the United States, little is known about youth attitudes toward smoke-free policies. Our research measures North Carolina middle school and high school students’ opinions about smoke-free policies in indoor and outdoor public places as well as private places such as vehicles, homes, and work environments.MethodsData come from the 2009 North Carolina Youth Tobacco Survey. The overall middle school response rate was 79.2% (n = 3,805 students); the overall high school response rate was 78.2% (n = 3,301 students). To account for the complex survey design and sampling weights, data were analyzed by using SAS survey procedures.ResultsMost middle school and high school students support smoke-free policies across all venues. Support for smoke-free policies for several venues is also strong among high school students who are current smokers and those who want to stop smoking.ConclusionUntil smoke-free legislation becomes universal, youth are at risk for exposure in many venues. The North Carolina legislature can protect the health and well-being of North Carolina youth by passing new legislation that is concordant with youth preferences regarding smoke-free policies

Evaluation of Community-Based Cessation Programs: How Do Smokers with Behavioral Health Conditions Fare?

Though persons with behavioral health conditions experience large disparities in tobacco use, questions about the efficacy of evidence-based tobacco use treatment remain understudied in community health settings. This evaluation examined outcomes from eight community-based tobacco cessation programs for participants with and without behavioral health conditions (n = 974 participants). The majority (64.8%) of participants reported one or more current behavioral health conditions, including mental illness and/or substance abuse. Participants who used cessation medication during the program and who attended more counseling sessions had an increased likelihood of being quit at 4-month follow-up. Quit rates were between 9.8% (intent-to-treat rate) and 30.6% (responder rate); behavioral health status did not negatively affect reported quit rates. Findings add to the growing literature evaluating community-based interventions within the behavioral health population

Problems in comprehension of informed consent in rural and peri-urban Mali, West Africa

Background: Clinical trials undertaken by industrialized nations in undeveloped nations pose several critical ethical dilemmas. One key potential problem concerns misunderstandings of the consent process by participants. Though other reports have begun to explore this area, needs remain to identify specific areas of misunderstanding. Purpose: To identify deficits in comprehension during consent processes in Mali, West Africa. Methods: After obtaining informed consent for participation for a malaria vaccine trial being conducted in two West African villages, we administered to participants a nine-item questionnaire testing their understanding of information relevant for their consent. After testing their ability to understand a multiple choice format, 78 of 100 subjects were administered the questionnaire in one village and 85 of 100 in the other. Results: Participants had difficulty comprehending several concepts relevant to informed consent: 90% of respondents did not understand withdrawal criterion, 93% did not understand the existence of study side effects, and 74% did not understand that they were enrolled in an investigation as opposed to receiving therapy. The response rate and percentage of correct answers was generally much higher in the village nearer an urban center than the more rural village. The percent of correct answers exceeded 50% for five questions in the urban village and for only two question in the more rural setting. Limitations: Potential limitations of this study are relating to translation, cultural differences in the notion of informed consent, staff differences between each village, the proportion who could not understand the survey instrument and the fact that the study explored participants’ understanding of the consent process but did not observe the process itself. Conclusions: This study illustrates potential areas of miscomprehension in the consent process in a developing country. The degree of miscomprehension found in this study appeared to be more than that found in similar studies conducted in industrialized nations. Despite efforts to obtain truly informed consent, several factors make it more challenging in the developing world. This research highlights the need for more comprehensive studies of consent in developing countries. Such studies may eventually aid investigators in identifying, targeting and addressing specific areas of miscomprehension and thereby improve the informed consent process in the developing world

Fate of conjugated natural and synthetic steroid estrogens in crude sewage and activated sludge batch studies

This document is the unedited author's version of a Submitted Work that was subsequently accepted for publication in Environmental Science & Technology, copyright © American Chemical Society after peer review. To access the final edited and published work see http://pubs.acs.org/doi/abs/10.1021/es801952h.Steroids are excreted from the human body in the conjugated form but are present in sewage influent and effluent as the free steroid, the major source of estrogenic activity observed in water courses. The fate of sulfate and glucuronide conjugated steroid estrogens was investigated in batch studies using activated sludge grown on synthetic sewage in a laboratory-scale Husmann simulation and crude sewage from the field. A clear distinction between the fate of sulfate and glucuronide conjugates was observed in both matrices, with sulfated conjugates proving more recalcitrant and glucuronide deconjugation preferential in crude sewage. For each conjugate, the free steroid was observed in the biotic samples. The degree of free steroid formation was dependent on the conjugate moiety, favoring the glucuronide. Subsequent degradation of the free steroid (and sorption to the activated sludge solid phase) was evaluated. Deconjugation followed the first order reaction rate with rate constants for 17α-ethinylestradiol 3-glucuronide, estriol 16α-glucuronide, and estrone 3-glucuronide determined as 0.32, 0.24, and 0.35 h respectively. The activated sludge solid retention time over the range of 3−9 days had 74 to 94% of sulfate conjugates remaining after 8 h. In contrast, a correlation between increasing temperature and decreasing 17α-ethinylestradiol 3-glucuronide concentrations in the activated sludge observed no conjugate present in the AS following 8 h at 22 °C Based on these batch studies and literature excretion profiles, a hypothesis is presented on which steroids and what form (glucuronide, sulfate, or free) will likely enter the sewage treatment plant.EPSR

Effects of framing proximal benefits of quitting and motivation to quit as a query on communications about tobacco constituents

Introduction: Little is known on how to communicate messages on tobacco constituents to tobacco users. This study manipulated three elements of a message in the context of a theorybased communication campaign about tobacco constituents: (1) latency of response efficacy (how soon expected health benefits would accrue), (2) self-efficacy (confidence about quitting), and (3) interrogative cue ("Ready to be tobacco-free?"). Methods: Smokers (N = 1669, 55.4% women) were recruited via an online platform, and were randomized to a 3 (Latency of response efficacy) × 2 (Self-efficacy) × 2 (Interrogative cue) factorial design. The dependent variables were believability, credibility, perceived effectiveness of the communication message, and action expectancies (likelihood of seeking additional information and help with quitting). Results: Latency of response efficacy influenced believability, perceived effectiveness, credibility, and action expectancies. In each case, scores were higher when specific health benefits were said to accrue within 1 month, as compared to general health benefits occurring in a few hours. The interrogative cue had a marginal positive effect on perceived effectiveness. The selfefficacy manipulation had no reliable effects, and there were no significant interactions among conditions. Conclusions: Smokers appear less persuaded by a communication message on constituents where general health benefits accrue immediately (within a few hours) than specific benefits over a longer timeframe (1 month). Additionally, smokers appeared to be more persuaded by messages with an interrogative cue. Such findings may help design more effective communication campaigns on tobacco constituents to smokers. Implications: This paper describes, for the first time, how components of tobacco constituent messages are perceived. We now know that smokers appear to be less persuaded by communication messages where general health benefits accrue immediately (within a few hours) than specific benefits over a longer timeframe (1 month). Additionally, including an interrogative cue ("Ready to be tobacco free?") may make messages more effective, whereas the self-efficacy manipulation designed to increase confidence about quitting had no effect. While messages were universally impactful across smoker subpopulations, everyday smokers and smokers with less trust in the government may be less receptive to communication campaigns
