J Adolesc Health 2024:S1054-139X(24)00377-X. [PMID: 39340497 DOI: 10.1016/j.jadohealth.2024.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 06/04/2024] [Accepted: 07/17/2024] [Indexed: 09/30/2024]
Abstract
PURPOSE Using multipronged recruitment strategies is crucial for reaching diverse smokers, yet research specifically focusing on youths is lacking. This prospective study compared the characteristics and abstinence outcomes of youth smokers enrolled in a youth-centered cessation service by three different methods. METHODS From December 2016 to February 2022, the Youth Quitline enrolled 1,197 smokers aged 10-25 (mean = 19.4) years through traditional method (incoming calls or referrals, n = 276), proactive outreach (n = 735), and online method (website or social media platforms, n = 186). Logistic regression was used to calculate the odds ratio (OR) of biochemically validated tobacco abstinence at 6 months by recruitment methods. RESULTS Proportionally more participants recruited via online method than traditional method and outreach had moderate to heavy nicotine dependence (53.2% vs. 40.9% vs. 27.6%, p < .001), poor self-rated health (27.6% vs. 21.9% vs. 12.3%, p < .001), and risk of depression (51.4% vs. 42.5% vs. 37.4%, p = .003). More participants recruited by outreach (71.6%) had no intention to quit in 30 days than traditional (58.3%) and online (59.7%) methods (p < .001). Compared with traditional method, the 6-month validated abstinence rate was similar in smokers recruited by online method (crude OR 0.77, 95% confidence interval 0.44-1.34) but significantly lower in those recruited by outreach (crude OR 0.44, 95% confidence interval 0.28-0.67). Results were similar after adjusting for sociodemographic and baseline predictors of abstinence. DISCUSSION Online recruitment can attract youth smokers with greater nicotine dependence and poorer health, whereas outreach can engage those with less motivation to quit. The lower quit rate in outreach-recruited participants indicated the need for more effective interventions.

Abstract
BACKGROUND The objective of the present study was to examine the short-term effectiveness of the national German quitline for smoking cessation. METHODS A parallel-group, two-arm, superiority, randomized controlled trial with data collection at baseline and post-intervention (three months from baseline) was conducted. Individuals were randomized to either the intervention group, receiving up to six telephone counselling calls, or the control group, receiving an active control intervention (self-help brochure). The primary outcome was the seven-day point prevalence abstinence at post-assessment. Secondary outcomes included changes in smoking-related cognitions and coping strategies from pre- to post-assessment, the perceived effectiveness of intervention components, and the satisfaction with the intervention. RESULTS A total of n = 905 adult daily smokers were assigned to either the intervention group (n = 477) or the control group (n = 428). Intention-to-treat analyses demonstrated that individuals allocated to the telephone counselling condition were more likely to achieve seven-day point prevalence abstinence at post-assessment compared to those allocated to the self-help brochure condition (41.1% vs. 23.1%; OR = 2.3, 95% CI [1.7, 3.1]). Participants who received the allocated intervention in both study groups displayed significant improvements in smoking-related cognitions and coping strategies with the intervention group showing greater enhancements than the control group. This pattern was also found regarding the perceived effectiveness of intervention components and the satisfaction with the intervention. CONCLUSION The present study provides first empirical evidence on the short-term effectiveness of the national German quitline for smoking cessation, highlighting its potential as an effective public health intervention to reduce the burden of disease associated with smoking. TRIAL REGISTRATION This study is registered in the German Clinical Trials Register (DRKS00025343). Date of registration: 2021/06/07.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E8575. [PMID: 33227929 PMCID: PMC7699292 DOI: 10.3390/ijerph17228575] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 11/10/2020] [Accepted: 11/18/2020] [Indexed: 12/23/2022]
Abstract
The growing popularity of heated tobacco products (HTPs) among youth may act as a gateway for smoking and jeopardize youth health. We aimed to describe the use of HTPs among youth smokers in Hong Kong and examine their risk awareness of HTPs as well as awareness of the proposed legislation. We conducted retrospective data analyses on the Youth Quitline Cohort (n = 731). We extracted participants' sociodemographic data, smoking profiles, and HTP use from 1 January 2017. Participants' HTP use increased from 5.7% in 2017 to 37.9% in 2020. Among the 731 participants, 175 were HTP users and 556 were HTP nonusers. Compared with nonusers, a significantly higher proportion of HTP users had tried using other tobacco products at least once. The most common reason for using HTPs was curiosity. HTP users were more likely than nonusers to misclassify HTPs as e-cigarettes; agree that HTPs were healthier and contained fewer harmful substances than conventional cigarettes; consider HTPs as a smoking cessation aid; and believe that HTPs could reduce conventional cigarette consumption. Overall, 61.2% of youth smokers disagreed with banning HTPs. Risk awareness of HTPs among youth might affect their likelihood of using these products. Stricter regulations on advertising and intensive health education are imperative to avoid misleading information and limit youth exposure to such harmful products.

Impact of COVID-19 on the Hong Kong Youth Quitline Service and Quitting Behaviors of Its Users. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17228397. [PMID: 33202764 PMCID: PMC7696005 DOI: 10.3390/ijerph17228397] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 11/04/2020] [Accepted: 11/12/2020] [Indexed: 01/08/2023]
Abstract
Tobacco use is a possible risk factor for contracting and spreading COVID-19. We aimed to describe the impact of the COVID-19 pandemic on the Youth Quitline service and quitting behaviors of its users in Hong Kong. We conducted a telephone survey involving 201 participants of the Youth Quitline service, and retrospectively analyzed the operation and use of Quitline since the COVID-19 outbreak in Hong Kong. The number of incoming calls to the Youth Quitline and the participants' quit rate has increased since the COVID-19 outbreak in Hong Kong. Many participants (68%) did not realize that tobacco use potentially increased their risk for developing and spreading COVID-19; however, 43% agreed that the pandemic motivated their intention to quit, and 83% changed their smoking habits during the pandemic. These changes were mainly due to wearing masks (30%), closure of bars/pubs (25%), suspension of classes (14%), and being unable to socialize with friends (24%). Overall, 58% reduced their tobacco use; of these participants, 66% reported a ≥50% reduction in daily cigarette consumption. The participants reduced their smoking during the COVID-19 pandemic despite lacking knowledge about the potentially increased risk for contracting COVID-19 from continued smoking. The pandemic could create new opportunities to motivate young smokers to quit smoking, especially those seeking support for smoking cessation, and may further contribute to reducing the risks posed by COVID-19.

Adolescent Smoking in Hong Kong: Prevalence, Psychosocial Correlates, and Prevention. J Adolesc Health 2019; 64:S19-S27. [PMID: 31122545 DOI: 10.1016/j.jadohealth.2019.01.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 01/04/2019] [Accepted: 01/04/2019] [Indexed: 11/24/2022]
Abstract
Preventing adolescent smoking is important as smoking is typically initiated by young people. This article reviews the prevalence, psychosocial correlates, and prevention of smoking in Hong Kong adolescents. The past 30-day smoking prevalence in adolescents decreased from 9.6% in 2003 to 2.5% in 2017. Tobacco advertisements, parental and best friends smoking, nonintact families, poor family relationships, lower socioeconomic status, being a new immigrant, poor knowledge of smoking-related harm, positive attitudes toward smoking, overestimation of peer smoking, and depressive symptoms were positively associated with smoking outcomes, whereas positive youth development, authoritative mother and permissive father, family functioning, school competence, and stronger tobacco industry denormalization beliefs were protective against smoking. Along with tobacco tax increase, ban on tobacco advertisements, smoke-free law and pictorial warnings, educational efforts through theater performances, social norms campaigns, and positive adolescent training programs have been conducted to prevent adolescent smoking. To achieve the ultimate goal of tobacco endgame, further tax increase, plain packaging, banning point-of-sale display of tobacco products, smoke-free area extension, and raising minimum age of purchase should be implemented. The government proposed law to ban e-cigarettes, and heated tobacco products should be passed soon to protect children and adolescents from using these products.

Abstract
BACKGROUND Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines. OBJECTIVES To evaluate the effect of telephone support to help smokers quit, including proactive or reactive counselling, or the provision of other information to smokers calling a helpline. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the ICTRP for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2018. SELECTION CRITERIA Randomised or quasi-randomised controlled trials which offered proactive or reactive telephone counselling to smokers to assist smoking cessation. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We pooled studies using a random-effects model and assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I2 statistic. In trials including smokers who did not call a quitline, we used meta-regression to investigate moderation of the effect of telephone counselling by the planned number of calls in the intervention, trial selection of participants that were motivated to quit, and the baseline support provided together with telephone counselling (either self-help only, brief face-to-face intervention, pharmacotherapy, or financial incentives). MAIN RESULTS We identified 104 trials including 111,653 participants that met the inclusion criteria. Participants were mostly adult smokers from the general population, but some studies included teenagers, pregnant women, and people with long-term or mental health conditions. Most trials (58.7%) were at high risk of bias, while 30.8% were at unclear risk, and only 11.5% were at low risk of bias for all domains assessed. Most studies (100/104) assessed proactive telephone counselling, as opposed to reactive forms.Among trials including smokers who contacted helplines (32,484 participants), quit rates were higher for smokers receiving multiple sessions of proactive counselling (risk ratio (RR) 1.38, 95% confidence interval (CI) 1.19 to 1.61; 14 trials, 32,484 participants; I2 = 72%) compared with a control condition providing self-help materials or brief counselling in a single call. Due to the substantial unexplained heterogeneity between studies, we downgraded the certainty of the evidence to moderate.In studies that recruited smokers who did not call a helpline, the provision of telephone counselling increased quit rates (RR 1.25, 95% CI 1.15 to 1.35; 65 trials, 41,233 participants; I2 = 52%). Due to the substantial unexplained heterogeneity between studies, we downgraded the certainty of the evidence to moderate. In subgroup analysis, we found no evidence that the effect of telephone counselling depended upon whether or not other interventions were provided (P = 0.21), no evidence that more intensive support was more effective than less intensive (P = 0.43), or that the effect of telephone support depended upon whether or not people were actively trying to quit smoking (P = 0.32). However, in meta-regression, telephone counselling was associated with greater effectiveness when provided as an adjunct to self-help written support (P < 0.01), or to a brief intervention from a health professional (P = 0.02); telephone counselling was less effective when provided as an adjunct to more intensive counselling. Further, telephone support was more effective for people who were motivated to try to quit smoking (P = 0.02). The findings from three additional trials of smokers who had not proactively called a helpline but were offered telephone counselling, found quit rates were higher in those offered three to five telephone calls compared to those offered just one call (RR 1.27, 95% CI 1.12 to 1.44; 2602 participants; I2 = 0%). AUTHORS' CONCLUSIONS There is moderate-certainty evidence that proactive telephone counselling aids smokers who seek help from quitlines, and moderate-certainty evidence that proactive telephone counselling increases quit rates in smokers in other settings. There is currently insufficient evidence to assess potential variations in effect from differences in the number of contacts, type or timing of telephone counselling, or when telephone counselling is provided as an adjunct to other smoking cessation therapies. Evidence was inconclusive on the effect of reactive telephone counselling, due to a limited number studies, which reflects the difficulty of studying this intervention.

Abstract
To ease the shortage of professionals, lay volunteers were trained to become health promoters and role models for a large community program to enhance physical activity, well-being, and neighborhood cohesion in socioeconomically disadvantaged groups in Hong Kong. This study aimed to examine the effects on health promoters (trainees) and the feasibility and acceptability of capability-building train-the-trainer workshops (TTTs) using Zero-time Exercise (ZTEx) to implement a community program for about 1,000 participants. A four-session (totally 8 hours) TTT introduced an evidence-based ZTEx intervention to enhance physical activity and well-being, and build capacity for community program implementation. Twenty-eight trainees actively participated in the TTT. Twenty-five and 21 trainees completed the 1- and 3-month questionnaires, respectively. Eleven trainees attended the 1-year focus group interview. Repeated measures analysis of variance and Friedman test were used to compare the parametric and nonparametric data, respectively. Qualitative data were analyzed using thematic content analysis. The trainees reduced their sedentary behavior and improved their interpersonal communication skills, knowledge, and attitude toward ZTEx, grip strength, balance, and perceived well-being. The community participants reported improvements in neighborhood cohesion and grip strength. The 1-year qualitative results supported the 3-month quantitative findings. This brief and innovative TTT affirmed the feasibility of using ZTEx and the role modeling approach for lay health promoters to reduce sedentary behavior and enhance physical activity, fitness, and well-being. They then contributed to the successful implementation of community programs that benefited many. This study provides a new model for building capacity for health promotion in the community.

Abstract
INTRODUCTION Young smokers often report depressive symptoms while receiving smoking cessation counseling. This study examines time patterns in the quitting process among young smokers with or without notable depressive symptoms. METHODS The quitting trajectories of young smokers aged 12 to 25 (n = 578) who called the Youth Quitline in Hong Kong between March 2006 and May 2011 were recorded and analyzed through multiple telephone sessions over periods of up to 6 months. The time patterns of young smokers who had or did not have notable depressive symptoms were compared using nonparametric Kaplan-Meier methods with log-rank tests. RESULTS Among young smokers with low levels of nicotine dependence, those who had notable depressive symptoms were less likely to initiate a quit attempt within 28 days after their baseline telephone intervention (probability = .38 vs. .60; P value = .04). Furthermore, young smokers who had notable depressive symptoms were less likely to remain abstinent from smoking for 2 days after starting a quit attempt (probability = .50 vs. .64; P value = .012). Young adults aged 18 or above were more likely to relapse into smoking (adjusted HR = 1.50, 95% CI = 1.01, 2.22). CONCLUSIONS Depressive symptoms may delay young smokers from initiating quit attempts and shorten their abstinence. A baseline screening process is suggested for identifying youths with co-occurring depressive disorder and nicotine dependence. Further studies should examine a collaborative model of smoking cessation that involves both counselors and physicians in preventing young smokers from rapid relapses after they make quit attempts.

Abstract
BACKGROUND Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines. OBJECTIVES To evaluate the effect of proactive and reactive telephone support via helplines and in other settings to help smokers quit. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2013. SELECTION CRITERIA randomized or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters. DATA COLLECTION AND ANALYSIS One author identified and data extracted trials, and a second author checked them. The main outcome measure was the risk ratio for abstinence from smoking after at least six months follow-up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I² statistic. We considered trials recruiting callers to quitlines separately from studies recruiting in other settings. Where appropriate, we pooled studies using a fixed-effect model. We used a meta-regression to investigate the effect of differences in planned number of calls, selection for motivation, and the nature of the control condition (self help only, minimal intervention, pharmacotherapy) in the group of studies recruiting in non-quitline settings. MAIN RESULTS Seventy-seven trials met the inclusion criteria. Some trials were judged to be at risk of bias in some domains but overall we did not judge the results to be at high risk of bias. Among smokers who contacted helplines, quit rates were higher for groups randomized to receive multiple sessions of proactive counselling (nine studies, > 24,000 participants, risk ratio (RR) for cessation at longest follow-up 1.37, 95% confidence interval (CI) 1.26 to 1.50). There was mixed evidence about whether increasing the number of calls altered quit rates but most trials used more than two calls. Three studies comparing different counselling approaches during a single quitline contact did not detect significant differences. Of three studies that tested the provision of access to a hotline two detected a significant benefit and one did not.Telephone counselling not initiated by calls to helplines also increased quitting (51 studies, > 30,000 participants, RR 1.27; 95% CI 1.20 to 1.36). In a meta-regression controlling for other factors the effect was estimated to be slightly larger if more calls were offered, and in trials that specifically recruited smokers motivated to try to quit. The relative extra benefit of counselling was smaller when it was provided in addition to pharmacotherapy (usually nicotine replacement therapy) than when the control group only received self-help material or a brief intervention.A further eight studies were too diverse to contribute to meta-analyses and are discussed separately. Two compared different intensities of counselling, both of which detected a dose response; one of these detected a benefit of multiple counselling sessions over a single call for people prescribed bupropion. The others tested a variety of interventions largely involving offering telephone counselling as part of a referral or systems change and none detected evidence of effect. AUTHORS' CONCLUSIONS Proactive telephone counselling aids smokers who seek help from quitlines. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness. There is limited evidence about the optimal number of calls. Proactive telephone counselling also helps people who receive it in other settings. There is some evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increase the chances of quitting compared to a minimal intervention such as providing standard self-help materials, or brief advice, or compared to pharmacotherapy alone.

Abstract
BACKGROUND Behavioral theories suggest that a past quit attempt influences psycho-social determinants to predict smokers' intention to quit, although no study has tested the hypothesis among youth smokers. METHODS A sample of 1561 Chinese secondary students, who were current smokers, were collected in a cross-sectional school-based survey in Hong Kong. RESULTS For the 943 students with past quit attempts, those with lower daily cigarette consumption; who perceived smoking would not elicit positive social responses from others; who had one parent/teacher who prohibited them to smoke; who were aware of the health hazards of smoking and being male smokers, were more likely to have an intention to quit smoking. For the 618 students without a past quit attempt, those who did not perceive any benefit from smoking; who had parents and teachers to prohibit them to smoke and who received social support to quit, were more likely to have an intention to quit smoking. CONCLUSION Strengthening the prohibition of smoking and providing social support may help initiate the intention to quit among youth smokers without a past quit attempt, while de-normalizing social images of smoking, providing information about the health hazards of smoking and relieving nicotine addiction may sustain quitting intentions among youth smokers with past quit attempts.

Abstract
INTRODUCTION New smoke-free legislation implemented in Hong Kong on 1 January 2007, prohibited smoking in the vast majority of indoor workplaces and public places. Experiences of western countries indicated that the need for smoking cessation services would increase after enactment of the smoke-free legislation, but no systematic study of this issue has been undertaken in Southeast Asia. The present study aimed to examine the impact of smoke-free legislation in promoting smoking cessation through a local quitline. METHODS The present study reports the results of a telephone survey using interrupted time-series analysis. We operated a toll-free smoking cessation hotline (quitline) for the general public from August 2005 to September 2007. The present study measured the percent change in the number of telephone calls received and handled before and after the smoke-free legislation. RESULTS We evaluated the quitline for 9-month periods before (January-September 2006) and after (January-September 2007) the smoke-free legislation was implemented. The call rate in the initial period was 27.6 per month compared with 34.9 per month after enactment of the legislation, a 26% increase. Based on interrupted time-series models, the initial impact of the smoke-free legislation was to increase the number of telephone calls received and handled per week (p < .001), but the impact was temporal and deteriorated within 6 months. DISCUSSION Implementation of the new smoke-free legislation had a short-term effect in promoting the utilization of a smoking cessation quitline in Hong Kong. A systematic and long-term tobacco control campaign should be combined with smoke-free legislation to promote and sustain smokers' interests in smoking cessation.

Abstract
BACKGROUND Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines. OBJECTIVES To evaluate the effect of proactive and reactive telephone support to help smokers quit. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group trials register for studies using free text term 'telephone*' or the keywords 'telephone counselling' or 'Hotlines' or 'Telephone' . Date of the most recent search: January 2006. SELECTION CRITERIA Randomized or quasi-randomized controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters. DATA COLLECTION AND ANALYSIS Trials were identified and data extracted by one person (LS) and checked by a second (TL). The main outcome measure was the odds ratio for abstinence from smoking after at least six months follow up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst sub groups of clinically comparable studies using the I(2) statistic. Where appropriate, we pooled studies using a fixed-effect model. A meta-regression was used to investigate the effect of differences in planned number of calls. MAIN RESULTS Forty-eight trials met the inclusion criteria. Among smokers who contacted helplines, quit rates were higher for groups randomised to receive multiple sessions of call-back counselling (eight studies, >18,000 participants, odds ratio (OR) for long term cessation 1.41, 95% confidence interval (CI) 1.27 to 1.57). Two of these studies showed a significant benefit of more intensive compared to less intensive intervention. Telephone counselling not initiated by calls to helplines also increased quitting (29 studies, >17,000 participants, OR 1.33, 95% CI 1.21 to 1.47). A meta-regression detected a significant association between the maximum number of planned calls and the effect size. There was clearer evidence of benefit in the subgroup of trials recruiting smokers motivated to quit. Of two studies that provided access to a hotline one showed a significant benefit and one did not. Two studies comparing different counselling approaches during a single session did not detect significant differences. A further seven studies were too diverse to contribute to meta-analyses and are discussed separately. AUTHORS' CONCLUSIONS Proactive telephone counselling helps smokers interested in quitting. There is evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increases the odds of quitting compared to a minimal intervention such as providing standard self-help materials, brief advice, or compared to pharmacotherapy alone. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness.
