BACKGROUND AND AIMS/OBJECTIVE:Three to ten minutes of smoking cessation advice by physicians is effective to increase quit rates but not routinely practised. We examined the effectiveness of physicians' very brief (about 30 seconds) smoking cessation intervention on quit rates among Chinese outpatient smokers. DESIGN/METHODS:A pragmatic, open-label, individually randomized controlled trial. SETTING/METHODS:Seventy-two medical outpatient departments of hospitals and/or community health centers in Guangdong, China. PARTICIPANTS/METHODS:Chinese adults who were daily cigarette smokers (N = 13,671, 99% males) were invited by their physician to participate during outpatient consultation. Smokers who were receiving smoking cessation treatment or were judged to needed specialist treatment for cessation were excluded. INTERVENTIONS/METHODS:The intervention group (n = 7,015) received a 30-second intervention including physician's very brief advice, a leaflet with graphic warnings, and a card with contact information of available cessation services. The control group (n = 6,656) received a very brief intervention on consuming vegetables and fruits. A total of 3,466 participants in the intervention group were further randomized to receive a brief booster advice from trained study personnel through telephone one month following their doctor visit. MEASUREMENTS/METHODS:The primary outcome was self-reported 7-day point prevalence abstinence in the intervention and control group at the 12-month follow-up. Secondary outcomes included self-reported 30-day abstinence and biochemically validated abstinence at 12-month follow-up. FINDINGS/RESULTS:By intention-to-treat, the intervention (vs. control) group had greater self-reported 7-day abstinence (9.1% vs. 7.8%; odds ratio (OR) 1.14; 95% Confidence Interval (CI) 1.03-1.26; P = .008) and 30-day abstinence (8.0% vs. 6.9%; OR 1.14 95% CI 1.03-1.27; P=0.01) at 12-month follow-up. The effect size increased when only participants who received the intervention from compliant physicians were included (7-day PPA OR = 1.42; 1.11-1.74). The group difference in biochemically validated abstinence was small (0.8% vs. 0.8%; OR 1.00 95% CI 0.71-1.42; P=0.99). CONCLUSION/CONCLUSIONS:A 30-second smoking cessation intervention increased self-reported abstinence among mainly male smokers in China at 12-month follow-up (risk difference = 1.3%) and should be feasible to provide in most settings and delivered by all healthcare professionals.

Importance/UNASSIGNED:Secondhand smoke (SHS) exposure is associated with many health conditions in children and adults. Millions of individuals in the US are currently exposed to SHS in their homes. Objective/UNASSIGNED:To investigate whether a federal ban on smoking in public housing settings was associated with a decrease in indoor SHS levels in New York City public housing developments 12 months after the policy's implementation. Design, Setting, and Participants/UNASSIGNED:This cohort study tracked indoor air quality longitudinally from April 2018 to September 2019 and used difference-in-differences analysis to examine SHS exposure before vs after implementation of the 2018 federal smoke-free housing (SFH) policy in 10 New York City Housing Authority (NYCHA) buildings vs 11 matched low-income buildings not subject to the SFH policy (ie, Section 8 buildings). Exposures/UNASSIGNED:Federal SFH policy implementation, beginning July 30, 2018. Main Outcomes and Measures/UNASSIGNED:Comparison of nicotine concentration levels from passive, bisulfate-coated filters before vs 12 months after implementation of the federal SFH policy. Secondary outcomes included changes in particulate matter less than 2.5 μm in diameter, measured with low-cost particle monitors, and counts of cigarette butts in common areas. Results/UNASSIGNED:Air quality was measured repeatedly in a total of 153 NYCHA and 110 Section 8 nonsmoking households as well as in 91 stairwells and hallways. Before the SFH policy implementation, air nicotine was detectable in 19 of 20 stairwells (95.0%) in NYCHA buildings and 15 of 19 stairwells (78.9%) in Section 8 buildings (P = .19) and in 17 of 19 hallways (89.5%) in NYCHA buildings and 14 of 23 hallways (60.9%) in Section 8 buildings (P = .004). Nicotine was detected less frequently inside nonsmoking apartments overall (26 of 263 [9.9%]) but more frequently in NYCHA apartments (20 of 153 [13.1%]) than in Section 8 apartments (6 of 110 [5.5%]) (P = .04). One year after policy implementation, there was no differential change over time in nicotine concentrations measured in stairwells (DID, 0.03 μg/m3; 95% CI, -0.99 to 1.06 μg/m3) or inside nonsmoking households (DID, -0.04 μg/m3; 95% CI, -0.24 to 0.15 μg/m3). Larger decreases in nicotine concentration were found in NYCHA hallways than in Section 8 hallways (DID, -0.43 μg/m3; 95% CI, -1.26 to 0.40 μg/m3). Conclusions and Relevance/UNASSIGNED:The findings suggest that there was no differential change in SHS in NYCHA buildings 12 months after SFH policy implementation. Additional support may be needed to ensure adherence to SFH policies.

INTRODUCTION/BACKGROUND:Smoking rates remain disproportionately high among Chinese immigrants in the US, particularly in males. Community-based smoking cessation services and quitlines have low engagement rates. Social media and text messaging programs can be effective in promoting quit rates and improving treatment engagement. This study examined Chinese immigrant smokers' barriers to accessing available smoking cessation services and patterns of using social media platforms and mobile phone text messaging. METHODS:We conducted in-depth interviews (n=30) and a brief survey (n=49) with adult Chinese immigrant smokers leaving in New York City in 2018. Qualitative interviews explored smokers' challenges with smoking cessation, barriers to accessing and using smoking cessation services, and experience using social media and text messaging. The quantitative survey assessed smoking and quitting behaviors, and social media and text messaging use patterns. RESULTS:Qualitative data revealed that participants faced various barriers to accessing cessation services, including the lack of awareness about services, skepticism about treatment effects, reliance on willpower for cessation, and time constraints. WeChat was mainly used to maintain social networking and acquire information. Participants rarely used text messaging or other social media platforms. Quantitative data showed that 55% of participants had no plan to quit smoking. Among those who reported past-year quit attempts (45%), 55% used cessation assistance. WeChat was the most frequently used platform with 94% users. CONCLUSIONS:WeChat has potential to serve as an easily accessible platform for delivering smoking cessation treatment among Chinese immigrant populations. Research is warranted to explore the feasibility and efficacy of employing WeChat in smoking cessation treatment.

Introduction/UNASSIGNED:Smoking prevalence is high in Viet Nam, yet tobacco dependence treatment (TDT) is not widely available. Methods/UNASSIGNED:We conducted a quasi-experimental study that compared the effectiveness of health care provider advice and assistance (ARM 1) vs. ARM 1 plus village health worker (VHW) counseling (ARM 2) on abstinence at 6-month follow-up. This study was embedded in a larger two-arm cluster randomized controlled trial (RCT) conducted in 26 community health centers (CHCs) in Viet Nam. Subjects (N=1,318) were adult patients who visited any participating CHC during the parent RCT intervention period and were self-identified as current tobacco users (cigarettes and/or waterpipe). Results/UNASSIGNED:At 6-month follow-up, abstinences rates in ARM 2 were significantly higher than ARM 1 (25.7% vs. 10.5%; p<.001). In multivariate analyses smokers in ARM 2 were almost three times more likely to quit compared with those in ARM 1 (adjusted odds ratio [AOR]=2.96, 95% confidence interval [CI]=1.78-4.92). Compared to cigarette-only smokers, waterpipe-only smokers (AOR=0.4, 95% CI=0.26-0.62) and dual users (AOR=0.62, 95% CI=0.45-0.86) were less likely to achieve abstinence, however the addition of VHW counseling (ARM 2) was associated with higher quit rates compared with ARM 1 alone for all smoker types. Conclusion/UNASSIGNED:A team approach in TDT programs that offers a referral system for health care providers to refer smokers to VHW-led cessation counseling is a promising and potentially scalable model for increasing access to evidence-based TDT and increasing quit rates in LMICs. TDT programs may need to adapt interventions to improve outcomes for waterpipe users.

BACKGROUND:Little is known about the risk and addiction perceptions of e-cigarettes among Asian populations. We examined e-cigarette perceptions among young adults in Hong Kong and the association between the perceptions and e-cigarette use patterns. METHODS:An online survey was administered to a convenience sample of Hong Kong residents aged 18-35 (N = 1186). Measures of e-cigarette perceptions included perceived harm and addictiveness of e-cigarettes, perceived harm of secondhand e-cigarette aerosol, and perceived popularity of e-cigarette use among peers. Separate multinomial logistic regression models were conducted to examine the associations between the four perceptions and former and current use of e-cigarettes relative to never use, controlling for demographics and current cigarette smoking status. Interactions of e-cigarette perceptions and current cigarette smoking were assessed in all models. Among current e-cigarette users, bivariate exact logistic regression models were used to examine the relationships between each of the perceptions and frequent e-cigarette use (≥3 days in past 30-day vs. 1-2 days). Among participants who had never used e-cigarettes, separate multivariable logistic regression models were conducted to examine the associations between e-cigarette perceptions and susceptibility to e-cigarette use. RESULTS:Overall, 97.2% of participants were aware of e-cigarettes, and 16.1% had tried e-cigarettes (11.3% former users; 4.8% current users). Young adults perceived e-cigarettes (and aerosol) as less harmful, less addictive, and less popular than cigarettes. Current cigarette smokers reported significantly lower perceived harmfulness and addictiveness of e-cigarettes, lower perceived harmfulness of e-cigarette aerosol, and higher perceived popularity than nonsmokers. The lower degree of harm and addiction perceptions, and higher levels of popularity perceptions were associated with greater odds of e-cigarette use, and these relationships were generally stronger among nonsmokers compared to current cigarette smokers. E-cigarette perceptions were not associated with frequent e-cigarette use. Perceiving e-cigarettes (and aerosol) as less harmful and less addictive were associated with greater susceptibility to e-cigarette use. Compared to nonsmokers, current smokers were more likely to report e-cigarette use and susceptibility. CONCLUSIONS:Continued monitoring of e-cigarette use and perceptions is needed. Educational programs should emphasize the potential harmful and addictive properties of e-cigarettes and the risks of secondhand exposure to e-cigarette aerosol.

Background: To assess residents' attitudes towards the United States (U.S.) Department of Housing and Urban Development's new smoke-free public housing policy, perceptions about barriers to policy implementation, and suggestions for optimizing implementation. Methods: In 2017, we conducted 10 focus groups among 91 residents (smokers and nonsmokers) living in New York City public housing. Results: Smokers and nonsmokers expressed skepticism about the public housing authority's capacity to enforce the policy due to widespread violations of the current smoke-free policy in common areas and pervasive use of marijuana in buildings. Most believed that resident engagement in the roll-out and providing smoking cessation services was important for compliance. Resident expressed concerns about evictions and worried that other building priorities (i.e., repairs, drug use) would be ignored with the focus now on smoke-free housing. Conclusions: Resident-endorsed strategies to optimize implementation effectiveness include improving the access to cessation services, ongoing resident engagement, education and communication to address misconceptions and concerns about enforcement, and placing smoke-free homes in a larger public housing authority healthy housing agenda.

BACKGROUND:Little is known about the prevalence and correlates of burnout among providers who work in small independent primary care practices (<5 providers). METHODS:We conducted a cross-sectional analysis by using data collected from 235 providers practicing in 174 small independent primary care practices in New York City. RESULTS:= .034). CONCLUSION/CONCLUSIONS:The burnout rate was relatively low among our sample of providers compared with previous surveys that focused primarily on larger practices. The independence and autonomy providers have in these small practices may provide some protection against symptoms of burnout. In addition, the relationship between adaptive reserve and lower rates of burnout point toward potential interventions for reducing burnout that include strengthening primary care practices' learning and development capacity.

PURPOSE/OBJECTIVE:We wanted to describe small, independent primary care practices' performance in meeting the Million Hearts ABCSs (aspirin use, blood pressure control, cholesterol management, and smoking screening and counseling), as well as on a composite measure that captured the extent to which multiple clinical targets are achieved for patients with a history of arteriosclerotic cardiovascular disease (ASCVD). We also explored relationships between practice characteristics and ABCS measures. METHODS:We conducted a cross-sectional, bivariate analysis using baseline data from 134 practices in New York City. ABCS data were extracted from practices' electronic health records and aggregated to the site level. Practice characteristics were obtained from surveys of clinicians and staff at each practice. RESULTS:= .011) than practices with multiple clinicians. CONCLUSION/CONCLUSIONS:Achieving targets for ABCS measures varied considerably across practices; however, small practices were meeting or exceeding Million Hearts goals (ie, 70% or greater). Practices were less likely to meet consistently clinical targets that apply to patients with a history of ASCVD risk factors. Greater emphasis is needed on providing support for small practices to address the complexity of managing patients with multiple risk factors for primary and secondary ASCVD.

INTRODUCTION/BACKGROUND:The use of alternative tobacco products (ATPs) is becoming increasingly popular among the youth. This study aimed to assess cigarette-only smoking, exclusive ATP use, and concurrent use (cigarettes and ATPs) among adolescents in Hong Kong. METHODS:We analyzed data of the Hong Kong School-based Survey on Smoking among Students 2012/13 from a representative sample of 45 857 secondary school students. Weighted prevalence of cigarette-only smoking, exclusive ATP use, and concurrent tobacco use were calculated. Multinomial logistic regression examined correlates of exclusive ATP use and concurrent use relative to cigarette-only smoking. Among current (past-30-days) cigarette smokers, multivariable logistic regression assessed whether ATP use was associated with nicotine dependence, quit intention and quit attempt. RESULTS:Overall, 5.8% of adolescents reported current tobacco use (2.1% cigarette-only smoking, 2.5% exclusive ATP use and 1.2% concurrent use). Compared with cigarette-only smoking, exclusive ATP use and concurrent tobacco use were associated with younger age, higher perceived family financial status, absence of cigarette smoking peers, poor knowledge about smoking and more frequent alcohol use. Among current cigarette smokers, ATP use was negatively associated with cigarette quit intention and quit attempt. CONCLUSIONS:ATP use was as prevalent as cigarette smoking among adolescents, and ATP users were different from cigarette smokers in many demographic and psychosocial factors. Tobacco control programs among youth should target different types of tobacco users and address all forms of tobacco products.
