BackgroundCultural trends in the United States, the nicotine consumer marketplace, and tobacco policies are changing. ObjectiveThe goal of this study was to identify and describe nicotine-related topics of conversation authored by the public and social bots on Twitter, including any misinformation or misconceptions that health education campaigns could potentially correct. MethodsTwitter posts containing the term “nicotine” were obtained from September 30, 2018 to October 1, 2019. Methods were used to distinguish between posts from social bots and nonbots. Text classifiers were used to identify topics in posts (n=300,360). ResultsPrevalent topics of posts included vaping, smoking, addiction, withdrawal, nicotine health risks, and quit nicotine, with mentions of going “cold turkey” and needing help in quitting. Cessation was a common topic, with mentions of quitting and stopping smoking. Social bots discussed unsubstantiated health claims including how hypnotherapy, acupuncture, magnets worn on the ears, and time spent in the sauna can help in smoking cessation. ConclusionsHealth education efforts are needed to correct unsubstantiated health claims on Twitter and ultimately direct individuals who want to quit smoking to evidence-based cessation strategies. Future interventions could be designed to follow these topics of discussions on Twitter and engage with members of the public about evidence-based cessation methods in near real time when people are contemplating cessation.

BackgroundInstagram, one of the most popular social media platforms among youth, offers a unique opportunity to examine blunts—partially or fully hollowed-out large cigars, little cigars, and cigarillos that are filled with marijuana. Cigarillo brands like Backwoods (Imperial Tobacco Group Brands LLC) have product features that facilitate blunt making, including a variety of brand-specific flavors that enhance the smoking experience (eg, honey, dark stout). Backwoods has an active online presence with a user-friendly website. ObjectiveThis study examined the extent to which Backwoods cigarillo–related posts on Instagram showed blunt making. Instagram offers a unique opportunity to examine blunt making as Instagram accounts will contain images reflective of behavior occurring without the prime of a researcher. MethodsData consisted of publicly available Instagram posts with the hashtag #backwoods collected from August 30 to September 12, 2018. Inclusion criteria for this study included an Instagram post with the hashtag “#backwoods”. Rules were established to content analyze posts. Categories included Type of post (ie, photo, video, or both); Blunt-related hashtags (ie, the corresponding post caption contained one or more hashtags like #blunts, #cannabis, and #weed that were identified in previous social media research); Rolling blunts (ie, the post contained an image of one or more individuals rolling a Backwoods cigarillo visibly containing marijuana); and Smoking blunts (ie, the post contained an image of one or more individuals blowing smoke or holding a lit blunt). We coded images for Product flavor reference, where a code of 1 showed a Backwoods cigarillo pack with a brand-specific flavor (eg, honey, dark stout, Russian crème) visible in the blunt-related image, and a code of 0 indicated that it was not visible anywhere in the image. ResultsAmong all posts (N=1206), 871 (72.2%) were coded as Blunt-related hashtags. A total of 125 (10.4%) images were coded as Smoking blunts, and 25 (2.1%) were coded as Rolling blunts (ie, Backwoods cigarillo explicitly used to roll blunts). Among blunt images, 434 of 836 (51.9%) were coded as Product flavor (ie, a Backwoods pack with a brand-specific flavor was visible). ConclusionsMost Backwoods cigarillo–related Instagram images were blunt-related, and these blunt-related images showed Backwoods packages indicating flavor preference. Continued monitoring and surveillance of blunt-related posts on Instagram is needed to inform policies and interventions that reduce the risk that youth may experiment with blunts. Specific policies could include restrictions on product features (eg, flavors, perforated lines, attractive resealable foil pouches, sale as singles) that facilitate blunt making.

BackgroundPublic health organizations have begun to use social media to increase awareness of health harm and positively improve health behavior. Little is known about effective strategies to disseminate health education messages digitally and ultimately achieve optimal audience engagement. ObjectiveThis study aims to assess the difference in audience engagement with identical antismoking health messages on three social media sites (Twitter, Facebook, and Instagram) and with a referring link to a tobacco prevention website cited in these messages. We hypothesized that health messages might not receive the same user engagement on these media, although these messages were identical and distributed at the same time. MethodsWe measured the effect of health promotion messages on the risk of smoking among users of three social media sites (Twitter, Facebook, and Instagram) and disseminated 1275 health messages between April 19 and July 12, 2017 (85 days). The identical messages were distributed at the same time and as organic (unpaid) and advertised (paid) messages, each including a link to an educational website with more information about the topic. Outcome measures included message engagement (ie, the click-through rate [CTR] of the social media messages) and educational website engagement (ie, the CTR on the educational website [wCTR]). To analyze the data and model relationships, we used mixed effects negative binomial regression, z-statistic, and the Hosmer-Lemeshow goodness-of-fit test. ResultsComparisons between social media sites showed that CTRs for identical antitobacco health messages differed significantly across social media (P

BackgroundPrior research suggests that social media–based public health campaigns are often targeted by countercampaigns. ObjectiveUsing reactance theory as the theoretical framework, this research characterizes the nature of public response to tobacco prevention messages disseminated via a social media–based campaign. We also examine whether agreement with the prevention messages is associated with comment tone and nature of the contribution to the overall discussion. MethodsUser comments to tobacco prevention messages, posted between April 19, 2017 and July 12, 2017, were extracted from Twitter, Facebook, and Instagram. Two coders categorized comments in terms of tone, agreement with message, nature of contribution, mentions of government agency and regulation, promotional or spam comments, and format of comment. Chi-square analyses tested associations between agreement with the message and tone of the public response and the nature of contributions to the discussions. ResultsOf the 1242 comments received (Twitter: n=1004; Facebook: n=176; Instagram: n=62), many comments used a negative tone (42.75%) and disagreed with the health messages (39.77%), while the majority made healthy contributions to the discussions (84.38%). Only 0.56% of messages mentioned government agencies, and only 0.48% of the comments were antiregulation. Comments employing a positive tone (84.13%) or making healthy contributions (69.11%) were more likely to agree with the campaign messages (P=0.01). Comments employing a negative tone (71.25%) or making toxic contributions (36.26%) generally disagreed with the messages (P=0.01). ConclusionsThe majority of user comments in response to a tobacco prevention campaign made healthy contributions. Our findings encourage the use of social media to promote dialogue about controversial health topics such as smoking. However, toxicity was characteristic of comments that disagreed with the health messages. Managing negative and toxic comments on social media is a crucial issue for social media–based tobacco prevention campaigns to consider.

BackgroundMobile health (mHealth) approaches offer potentially affordable ways to support the care of HIV-infected patients in overstretched health care systems. However, only few studies have analyzed the costs associated with mHealth solutions for HIV care. ObjectiveThe aim of this study was to estimate the total incremental costs and incremental cost per beneficiary of an interactive SMS text messaging support intervention within a clinical trial. MethodsThe Mobile WAChX trial (NCT02400671) evaluates an interactive semiautomated SMS text messaging intervention to improve adherence to antiretroviral therapy and retention in care among peripartum women infected with HIV in Kenya to reduce the mother-to-child transmission of HIV. Women were randomized to receive one-way versus two-way SMS text messages. Messages were sent weekly, and these messages included motivational and educational content and visit reminders; two-way messaging enabled prompt consultation with the nurse as needed. Microcosting methods were used to collect resource-use data related to implementing the Mobile WAChX SMS text messaging intervention. At 2 sites (Nairobi and Western Kenya), we conducted semistructured interviews with health personnel to identify startup and recurrent activities by obtaining information on the personnel, supplies, and equipment. Data on expenditures and prices from project expense reports, administrative records, and published government salary data were included to estimate the total incremental costs. Using a public provider perspective, we estimated incremental unit costs per beneficiary and per contact during 2017. ResultsThe weighted average annual incremental costs for the two-way SMS text messaging group were US $3725 per facility, US $62 per beneficiary, and US $0.85 per contact to reach 115 beneficiaries. For the one-way SMS text messaging group, the weighted average annual incremental costs were US $2542 per facility, US $41 per beneficiary, and US $0.66 per contact to reach 117 beneficiaries. The largest cost shares were for the personnel: 48.2% (US $1794/US $3725) in two-way and 32.4% (US $825/US $2542) in one-way SMS text messaging groups. Costs associated with software development and communication accounted for 29.9% (US $1872/US $6267) of the costs in both intervention arms (US $1042 vs US $830, respectively). ConclusionsCost information for budgeting and financial planning is relevant for implementing mHealth interventions in national health plans. Given the proportion of costs related to systems development, it is likely that costs per beneficiary will decline with the scale-up of the interventions.

BackgroundPrevention of mother-to-child HIV transmission (PMTCT) relies on long-term adherence to antiretroviral therapy (ART). Mobile health approaches, such as text messaging (short message service, SMS), may improve adherence in some clinical contexts, but it is unclear what SMS content is desired to improve PMTCT-ART adherence. ObjectiveWe aimed to explore the SMS content preferences related to engagement in PMTCT care among women, male partners, and health care workers. The message content was used to inform an ongoing randomized trial to enhance the PMTCT-ART adherence. MethodsWe conducted 10 focus group discussions with 87 HIV-infected pregnant or postpartum women and semistructured individual interviews with 15 male partners of HIV-infected women and 30 health care workers from HIV and maternal child health clinics in Kenya. All interviews were recorded, translated, and transcribed. We analyzed transcripts using deductive and inductive approaches to characterize women’s, partners’, and health care workers’ perceptions of text message content. ResultsAll women and male partners, and most health care workers viewed text messages as a useful strategy to improve engagement in PMTCT care. Women desired messages spanning 3 distinct content domains: (1) educational messages on PMTCT and maternal child health, (2) reminder messages regarding clinic visits and adherence, and (3) encouraging messages that provide emotional support. While all groups valued reminder and educational messages, women highlighted emotional support more than the other groups (partners or health care workers). In addition, women felt that encouraging messages would assist with acceptance of their HIV status, support disclosure, improve patient-provider relationship, and provide support for HIV-related challenges. All 3 groups valued not only messages to support PMTCT or HIV care but also messages that addressed general maternal child health topics, stressing that both HIV- and maternal child health–related messages should be part of an SMS system for PMTCT. ConclusionsWomen, male partners, and health care workers endorsed SMS text messaging as a strategy to improve PMTCT and maternal child health outcomes. Our results highlight the specific ways in which text messaging can encourage and support HIV-infected women in PMTCT to remain in care, adhere to treatment, and care for themselves and their children.

Prevention of COVID-19 with vaccine requires multiple doses and updated boosters to maintain protection; however currently there are no tests that can measure immunity and guide clinical decisions about timing of booster doses. This study examined the association between the risk of COVID-19 breakthrough infections and receptor binding domain (RBD) antibody levels and receipt of booster of COVID-19 vaccines. A community sample of Los Angeles County adults were surveyed between 2021 and 2022 to determine if they had a self-reported breakthrough infection. Predictors included RBD antibody levels, measured by binding antibody responses to the ancestral strain at baseline and self-reported booster shot during the study period. Of the 859 participants, 182 (21%) reported a breakthrough infection. Irrespective of the level of antibodies, the risk of breakthrough infection was similar, ranging from 19 to 23% (P = 0.78). The risk of breakthrough infections was lower among participants who had a booster shot (P = 0.004). The protective effect of a booster shot did not vary by antibody levels prior to receiving the booster. This study found no association between RBD antibody levels and risk of breakthrough infections, while the receipt of booster was associated with lower risk of breakthrough infections, which was independent of pre-booster antibody levels. Therefore, antibody levels might not be a useful guide for clinical decisions about timing of booster doses.

Mobile health (mHealth) short message system (SMS) interventions for maternal and child health (MCH) are being implemented globally. In many low- and middle-income settings in which these mHealth interventions are being rolled out, stillbirths and neonatal and infant deaths are common. It is important that mHealth solutions do not exacerbate emotional stress and pain by continuing with routine messaging for pregnancy or infant care when someone has experienced loss. In this brief viewpoint paper, we argue that SMS programs for maternal and child health need to adapt and make available messaging for miscarriage, stillbirth, and infant loss.

Background: E-cigarette companies use YouTube to foster brand awareness, market their products, and interact with current and future tobacco users. However, research on the official YouTube channels of e-cigarette companies is limited. This study determined the themes of, and degree of user engagement with, videos posted to the official channels of e-cigarette companies on YouTube. Methods: Data were collected from the official YouTube channels of seven e-cigarette companies by scraping (i.e., electronically copying) the videos. The earliest video was posted on October 10, 2013, and the most recent video was posted on April 22, 2021 (n = 260). An inductive approach was used to identify themes in the data. User engagement with posts including number of likes, dislikes, and comments were also collected. Results: Prevalent themes included branding (n = 250 of 260 videos, 96%), youth use (n = 222, 85%), and tobacco use (n = 210, 81%), while less common themes included misleading health statements (n = 4, 2%), personal choice (n = 4, 2%), and antitobacco (n = 2, 1%). Videos that contained the themes testimonial, product design features, and instructional received the highest mean number of likes. Videos that contained the themes antitobacco, cessation, and testimonial received the highest mean number of dislikes. The 260 videos in this study were collectively viewed 6,619,700 times as of May 5, 2021. Conclusions: Videos from the official YouTube channels of seven e-cigarette companies often focused on branding and user experience but rarely mentioned cessation. While videos about cessation were rare, they received the second highest mean number of dislikes. Future research should assess the impact of exposure to e-cigarette-related content on YouTube and e-cigarette-related attitudes and behaviors.

Following the homicide of George Floyd on May 25, 2020, young adults participated widely in national protests against racism and police brutality. This study examined temporal trends and correlates of self-reported distress about police brutality from May 18 to August 3, 2020 among a cohort of young adults (ages 19-22; N = 2,080) from Los Angeles, CA. Bivariate and adjusted linear regression models estimated the association between survey completion date and distress about police brutality. Distress about police brutality increased substantially in the 2-weeks after Floyd's death (43% increase over baseline), but gradually declined over the ensuing 8 weeks to a 19% increase over baseline. Results suggest that police violence is contributing to stress and worry among young adults.

IntroductionE-cigarette users typically initiate vaping with flavoured e-liquids. People who vape flavours tend to underestimate the harm of vaping. We examined the inter-relationship between flavour preference, vaping for cessation purposes, e-cigarette dependence, e-cigarette harm perception and purchase/use intention, given a hypothetical flavour ban. We hypothesised that non-tobacco flavour preference and vaping for cessation would be negatively associated with harm perception of e-cigarettes and intention to continue vaping if a flavour ban occurred and that these effects would be mediated by e-cigarette dependence.MethodsFrom July 2019 to March 2020, we conducted intercept interviews with 276 customers at 44 vape shops in California. The predictor variables were flavour preference and vaping for cessation. The outcome variables were harm perception of e-cigarettes and intention to purchase/use, given a hypothetical flavour ban. Multilevel structural equation modelling tested whether e-cigarette dependence mediates the effects of flavour preference on hypothetical continued vaping and purchase.ResultsThose who preferred flavours showed significantly lower intention to purchase e-liquids (β=-0.28, p

IntroductionIt is established that higher prediagnostic circulating androgen and estrogen levels are associated with increased breast cancer risk in premenopausal and postmenopausal women. Pooled analyses in postmenopausal women report higher androgen and estrogen levels in current heavy cigarette smokers compared to nonsmokers. However, evidence among premenopausal women has been inconsistent.Aims and methodsWe conducted a systematic review and meta-analysis to estimate differences in standardized mean hormone levels among current premenopausal smokers compared to nonsmokers. We reviewed and collated publications with sex hormone levels by smoking status among healthy, premenopausal women who were nonusers of exogenous hormones, including oral contraceptives, using PubMed through December 2019. A random effects meta-analysis was conducted to combine the standardized mean differences (SMD) and 95% confidence intervals (CIs) for estradiol, progesterone, testosterone, dehydroepiandrosterone, dehydroepiandrosterone-sulfate, and sex hormone-binding globulin by smoking status. Findings were summarized by menstrual cycle phase and overall.ResultsNineteen published peer-reviewed articles were included. Significantly increased testosterone levels among smokers compared to nonsmokers were identified from cross-sectional studies with varied menstrual phase timing (SMD 0.14; 95% CI 0.0005, 0.29) and significantly increased dehydroepiandrosterone-sulfate levels were found over all phases (SMD 0.12; 95% CI 0.01, 0.22). However, substantial heterogeneity existed in these studies.ConclusionsThis meta-analysis suggests that smoking may increase blood androgen levels in healthy premenopausal women which may increase breast cancer risk; however, the differences were modest. Larger and covariate-adjusted studies with standardized collection over the menstrual cycle are needed to better understand this relationship and to reduce heterogeneity.ImplicationsExisting research has described associations between high prediagnostic estradiol and androgen levels with breast cancer risk among premenopausal women and has established active smoking as a breast cancer risk factor. However, the smoking and circulating sex hormone associations among premenopausal women remain inadequately studied. In this meta-analysis, we identified an association between smoking and higher mean testosterone and dehydroepiandrosterone-sulfate levels with consideration of menstrual phase, providing additional information on smoking's potential pathway to premenopausal breast cancer.

PurposeTo evaluate the association between lifetime personal cigarette smoking and young-onset breast cancer (YOBC; diagnosed

Social media platforms offer opportunities for targeted health communication ads to improve tobacco and cannabis prevention efforts. This study described tobacco and cannabis-related ads targeted towards adolescents and young adults on Snapchat. Data comprised of publicly available tobacco (n = 70) and cannabis-related (n = 64) ads from Snapchat in 2019. Identified themes included: Health consequences (Health effects of tobacco or cannabis use), Financial & legal consequences (Adverse financial or legal implications of substance use), Quitting (Resources for cessation), Industry tactics (Tobacco industry misleads individuals), Policy advocacy (Cannabis law reforms or legalization). Ad performance metrics included average Ad Impressions (number of views per ad) and Ad Spend (cost per ad). Ads were also categorized by Sponsoring Organizations (Government or Advocacy organizations). Health Consequences was the predominant theme followed by Quitting among tobacco-related ads. Government organizations sponsored most tobacco-related ads. Tobacco-related ads targeting adolescents received mean = 4,122,071 impressions and cost mean = $10,385.6 per ad. Tobacco-related ads targeting young adults received mean = 2,151,217 impressions and cost mean = $5,382.1 per ad. Health Consequences was a predominant theme among cannabis-related ads followed by Policy Advocacy. Advocacy organizations sponsored most cannabis-related ads targeting young adults. Cannabis-related ads targeting adolescents received mean = 415,293.8 impressions and cost mean=$793.92 per ad. Cannabis-related ads targeting young adults received mean = 293,267.7 impressions, and cost mean = $740.58. Government and advocacy organization sponsored ads reached millions of adolescents and young adults on Snapchat. Prevention campaigns may consider these number of impressions and cost per ad by theme when designing platform specific ads in the future.

Oral nicotine pouches may appeal to young adult current nicotine/tobacco users interested in alternative forms of nicotine that lack pulmonary exposure, but may also appeal to young adult non-users of nicotine/tobacco products. We used data from a 2020 remote digital survey of an ongoing cohort study of young adults from Southern California (aged 19-23) to examine differences in pouch perceptions and use willingness across nicotine/tobacco use statuses. Participants who had never used nicotine pouches (N = 1167) viewed text/imagery from mass-marketed pouch packaging and advertising, then completed measures of willingness to use nicotine pouches, pouch harm perceptions, and hypothetical choice of cigarettes or e-cigarettes over pouches. Willingness to use pouches was significantly higher among non-combustible only (33.8%), combustible only (29.3%), and dual (43.9%) users than non-users (14.7%). Overall, 49.1% of participants were uncertain whether pouches were less harmful than cigarettes and 52.4% were uncertain whether pouches were less harmful than e-cigarettes. Relative harm perceptions did not significantly differ by tobacco use status. Those using non-combustible products (either alone or as part of dual use with combustible tobacco) had greater odds than non-users of reporting that they would use e-cigarettes over nicotine pouches. By contrast, all tobacco product user groups reported greater odds than non-users that they would use cigarettes over pouches. In sum, a sizable minority of young adults might be willing to try using nicotine pouches, but most are uncertain about the relative harm of pouches.

Background: The prevalence of electronic-cigarette (e-cigarette) product placement in music videos is on the rise and currently unregulated. This promotional activity is concerning given the popularity of music videos among young adults. Aims: We examined associations between self-reported levels of exposure to music videos with any e-cigarette product placement or imagery and susceptibility to use e-cigarettes and e-cigarette use. Method: A representative sample of young adults (18-24 years of age), residing in California (n = 1,280), completed online surveys assessing self-reported exposure to music videos with e-cigarette product placement or imagery and susceptibility to use e-cigarettes and e-cigarette use. Adjusted and weighted regression analyses were used for statistical analyses. Results: Participants exposed to any e-cigarette product placement or imagery in music videos were more likely to report lifetime e-cigarette use (relative risk ratio ["RRR"]: 2.81) and past 30-day use ("RRR": 3.64) compared with participants with no exposure. Additionally, participants with greater levels of exposure were more likely to report lifetime e-cigarette use ("RRR": 1.13) and past 30-day use ("RRR": 1.20) compared with participants with lower levels of exposure. Among those with any exposure, participants younger than 21 years of age (i.e., under the tobacco purchasing age in the United States) were more likely to report lifetime e-cigarette use ("RRR": 4.68) compared with those aged 21 years and older. Discussion and Conclusion: Restricting e-cigarette product placement or imagery in music videos may minimize marketing exposure and risk for vaping among young adults, especially among those under the tobacco purchasing age.

BackgroundRecent changes in California's tobacco and cannabis policies could impact the retail availability of little cigars/cigarillos (LCCs) and blunt wraps that are used for blunt smoking. This study was intended to test whether tobacco flavor bans and minimum pack sizes of LCCs have reduced tobacco availability in California jurisdictions, whereas, permissive policies on sales and marketing of cannabis increased availability.MethodsMeasures of retail availability of LCCs and blunt wraps were obtained from the 2016-2019 longitudinal sample of licensed tobacco retailers (LTRs, n = 4062) from California's Healthy Stores for Healthy Communities campaign. Additional data sources included the California Cannabis Local Laws database and geographic location of 1063 cannabis retailers used for constructing a spatial index of accessibility to the LTRs. Two-level generalized structural equation models were developed to assess effects of store- and jurisdiction-level predictors of change in tobacco availability (+, -, no change).ResultsNeither permissive cannabis policies nor accessibility to cannabis retailers were associated with an increase in retail availability of the tobacco products. Enactment of a tobacco flavor ban, however, was associated with reduced availability of LCCs and blunt wraps, which was more pronounced in jurisdictions that had permissive cannabis policies (i.e. policy interaction).ConclusionsA tobacco flavor ban may be an effective strategy to reduce retail availability of LCCs, blunt wraps and possibly other tobacco in California jurisdictions. This finding is of particular relevance as the tobacco industry has successfully petitioned for a referendum vote on California's statewide flavor ban in the 2022 election.

ObjectivesIn February 2020, the US Food and Drug Administration issued a guidance restricting the sales and distribution of cartridge-based e-cigarettes with flavours other than tobacco and menthol. Disposable devices were exempt from this guidance. This study examined the prevalence of disposable pod use and flavour preference compared with refillable pod and other e-cigarette users among vape shop customers.DesignCross-sectional study.SettingIn July 2019-March 2020, trained data collectors visited 44 vape shops in California with permission to recruit customers from shop owners.ParticipantsIntercept interviews with 276 customers were conducted.Outcomes and proceduresCustomers were grouped based on self-reported device type used most often (disposable pod, refillable pod and other e-cigarettes). Groups were compared on self-reported demographics, flavours preferred, daily e-cigarette use, preferred nicotine concentration levels and cigarette use.ResultsOf the 276 customers surveyed, 11.2% used disposable pods in the past 30 days. Among disposable pod users, fruit/candy (80.7%), mint (77.4%) and menthol (67.7%) were common preferred flavours, while tobacco flavours were less commonly preferred (19.4%). When compared with refillable pod and other non-pod e-cigarette device users, disposable pod users were younger, used higher nicotine concentration levels, were more likely to prefer mint and menthol flavours and use e-cigarettes as their first product, while less likely to ever use cigarettes and use e-cigarettes daily.DiscussionDespite using higher nicotine levels and preferred menthol/mint flavours more often than users of other devices, disposable pod users reported lower prevalence of lifetime smoking and daily vaping and were younger. Given the current findings, regulations addressing non-tobacco flavours and nicotine concentration in disposable pod devices merit consideration in efforts to reduce vaping in younger adult never smokers.

Mindfulness-based interventions (MBIs) may offer a means for Latinx families to ameliorate stress, enhance emotion regulation, and foster social support. We assessed pilot data from Latinx parents in Eastside Los Angeles (n = 27) matched with their children aged 10-16 (n = 32) to determine whether participation in a community-derived MBI was associated with greater improvements in dispositional mindfulness, perceived stress, emotion regulation, and family social support compared to a control condition. Compared to the control group, parents in the MBI group showed greater reductions in perceived stress scale (PSS) scores (B =  - 2.94, 95% CI [- 5.58, - 0.39], p = 0.029), while their children reported greater increases in perceived social support from family (B = 2.32, 95% CI [0.26, 4.38], p = 0.027). Findings show a community-derived MBI may improve stress in Latinx parents and social support for their children.

IntroductionPast studies have documented disparities in regulation compliance among tobacco retailers with respect to ethnic diversity in neighbourhoods. This study investigated the association between compliance with the Food and Drug Administration (FDA) and California state rules and neighbourhood ethnic composition of a vape shop location.MethodsWe recruited 122 vape shops located in 'ethnic enclave' neighbourhoods in Southern California. Trained teams of data collectors visited each of the consented vape shops and coded items in the shops that were visible and on display. Location data for the percentages of ethnic composition for a given city were obtained from the U.S. Census Bureau, American FactFinder. Multilevel logistic regression models examined the relationship between the city-level neighbourhood ethnic composition and vape shop rule violation status: not displaying Ask4ID sign and offering free samples.ResultsVape shops located in neighbourhoods/communities with more white residents were significantly less likely to not display Ask4ID sign (p=0.03) and less likely to offer free sampling (p=0.009), controlling for other neighbourhood ethnic characteristics.DiscussionGreater enforcement for proper signage display is needed for vape shops located in racial/ethnic minority locations to ensure that minors are discouraged from purchasing e-products.

BackgroundIn response to the recent government restrictions, flavored JUUL products, which are rechargeable closed-system electronic cigarettes (e-cigarettes), are no longer available for sale. However, disposable closed-system products such as the flavored Puff Bar e-cigarette continues to be available. If e-cigarette consumers simply switch between products during the current government restrictions limited to 1 type of product over another, then such restrictions would be less effective. A step forward in this line of research is to understand how the public discusses these products by examining discourse referencing both Puff Bar and JUUL in the same conversation. Twitter data provide ample opportunity to capture such early trends that could be used to help public health researchers stay abreast of the rapidly changing e-cigarette marketplace.ObjectiveThe goal of this study was to examine public discourse referencing both Puff Bar and JUUL products in the same conversation on Twitter.MethodsWe collected data from Twitter's streaming application programming interface between July 16, 2019, and August 29, 2020, which included both "Puff Bar" and "JUUL" (n=2632). We then used an inductive approach to become familiar with the data and generate a codebook to identify common themes. Saturation was determined to be reached with 10 themes.ResultsPosts often mentioned flavors, dual use, design features, youth use, health risks, switching 1 product for the other, price, confusion over the differences between products, longevity of the products, and nicotine concentration.ConclusionsOn examining the public's conversations about Puff Bar and JUUL products on Twitter, having described themes in posts, this study aimed to help the tobacco control community stay informed about 2 popular e-cigarette products with different device features, which can be potentially substituted for one another. Future health communication campaigns may consider targeting the health consequences of using multiple e-cigarette products or dual use to reduce exposure to high levels of nicotine among younger populations.

The current study was designed to address gaps in the existing literature by examining the role of discrimination and familism values as predictors of multiple forms of prosocial behaviors across time in a sample of recent immigrant Latino/a adolescents. Participants were 302 recent immigrant Latino/a adolescents (53.3% male; average age 14.51 years, range = 13-17). Data were collected from adolescents in two US cities: Los Angeles (n = 150) and Miami (n = 152). Adolescents completed measures of their own discrimination experiences, familism values, and tendency to engage in six forms of prosocial behaviors. Results indicated generally positive links between familism values and prosocial behaviors. Discrimination also positively predicted public prosocial behaviors and negatively predicted altruistic prosocial behaviors. We discuss the development of cultural processes and perceptions of discrimination experiences, and how these factors predict helping behaviors among immigrant adolescents.

Background: School-based COVID-19 testing is a potential strategy to limit COVID-19 transmission among youth in congregate settings such as schools, sports programs, and summer camps. The purpose of this study is to evaluate the feasibility and effectiveness of frequent rapid antigen testing at a supervised distance-learning setting for elementary and middle school children while their schools were closed. Methods: This evaluation examines participation rates and testing data in addition to qualitative analysis of focus groups from a Los Angeles City-sponsored rapid antigen testing pilot program. In total, 434 children and staff were enrolled in the 13-week pilot program in the spring of 2021. Results: In this pilot program, 2482 rapid antigen tests were administered, resulting in 3 positive test results, 1 of which was a false positive (confirmed by polymerase chain reaction testing) and 0 outbreaks or community spread. Conclusions: Throughout this pilot program, implementing rapid antigen tests allowed for the quick identification and isolation of potentially COVID-19-positive children, improved perceived safety for parents and staff who interact with children, and demonstrated the ability for staff and non-health care professionals in a school-based setting to implement a widespread COVID-19 screening program with minimal training.

With a growing population of Latinx youth immigrating to the United States, it is important to understand how Latinx youth adapt to mainstream U.S. culture. Given that the majority of research examining social development among recent immigrant adolescents has focused on negative adjustment outcomes, research examining positive social behaviors is needed to avoid deficit approaches to their development, gain a holistic understanding of youth development, and improve interventions with this population.This study examined the associations among trajectories in cultural integration and multiple prosocial behaviors among recent immigrant U.S. Latinx adolescents in Miami, Florida and Los Angeles, California. Adolescents (N = 302; 53.3% males; M age = 14.51 years) completed measures of integration and prosocial behaviors across six time points. Latent growth curve models indicated that integration significantly increased, though this growth tapered off over time. The growth in prosocial behaviors depended on the specific form of helping assessed. While the growth in altruistic and compliant prosocial behaviors was stagnant, there was an increase in anonymous prosocial behaviors and a decrease in public and dire prosocial behaviors. Emotional behaviors did not linearly change, though slightly tapered off by the final time points. Parallel process latent growth curve model results indicated positive correlations between the slopes of cultural integration and most forms of prosocial behaviors. These findings highlight the positive role of cultural integration as an acculturative process for U.S. Latinx youth and the multidimensionality of prosocial behaviors.

With a growing population of Latinx youth immigrating to the United States, it is important to understand how Latinx youth adapt to mainstream U.S. culture. Given that the majority of research examining social development among recent immigrant adolescents has focused on negative adjustment outcomes, research examining positive social behaviors is needed to avoid deficit approaches to their development, gain a holistic understanding of youth development, and improve interventions with this population.This study examined the associations among trajectories in cultural integration and multiple prosocial behaviors among recent immigrant U.S. Latinx adolescents in Miami, Florida and Los Angeles, California. Adolescents (N = 302; 53.3% males; M age = 14.51 years) completed measures of integration and prosocial behaviors across six time points. Latent growth curve models indicated that integration significantly increased, though this growth tapered off over time. The growth in prosocial behaviors depended on the specific form of helping assessed. While the growth in altruistic and compliant prosocial behaviors was stagnant, there was an increase in anonymous prosocial behaviors and a decrease in public and dire prosocial behaviors. Emotional behaviors did not linearly change, though slightly tapered off by the final time points. Parallel process latent growth curve model results indicated positive correlations between the slopes of cultural integration and most forms of prosocial behaviors. These findings highlight the positive role of cultural integration as an acculturative process for U.S. Latinx youth and the multidimensionality of prosocial behaviors.
