RESUMO
ObjectivesãIn response to the steady rise in the number of cases of mpox in nonendemic countries, starting with an outbreak in the United Kingdom in May 2022, the World Health Organization declared a public health emergency of international concern on July 23, 2022. As of November 13, 2022, seven cases of mpox have been reported in Japan.MethodsãA community engagement approach was applied to prevent the spread of mpox in Japan.ResultsãA tripartite partnership between academia, community, and government (ACG) was established to promote multisectoral communication between vulnerable communities, medical personnel involved in diagnosis and treatment, public health specialists at public health centers, epidemiologists at the National Institute of Infectious Diseases (NIID), and government and public administration. Through information sharing, this ACG partnership can translate accurate information into effective infection control measures.ConclusionãBy developing and maintaining the ACG partnership, an environment will be created that allows an immediate response to future public health crises affecting vulnerable communities. This Practice Report describes the process of establishing an ACG partnership.

Objective This report aimed to present policy recommendations on the regulation of heated tobacco products based on a review of the literature on the use of heated tobacco products, component analysis of harmful chemical substances, and product characteristics as nicotine delivery device, and on an examination of the influence of the product's increasing usage to the main measures of tobacco control.Methods The literature search was performed using Japan Centra Revuo Medicina and PubMED database. The search yielded 11 articles that examined the use of heated tobacco products, component analysis of harmful chemical substances, and product characteristics as nicotine delivery device. Eight articles were additionally collected from reports of public health research in Japan and public reports in foreign countries. The six main policies advocated by World Health Organization as MPOWER (Monitor, Protect, Offer, Warn, Enforce, Raise) were adopted in considering the expected influence of this product's increasing usage this product epidemic on tobacco control. In addition to the abovementioned 19 articles, 26 documents and materials related to the status of tobacco control were collected and used to examine the influence of the product's increasing usage to the main measures of tobacco control.Results In Japan, heated tobacco products have been available since December 2013, and the spread of use has risen remarkably since 2016. As of October 2016, Japan consumed more than 90% of the heated tobacco products sold internationally. Compared with cigarettes, heated tobacco products can reduce exposure to harmful substances except nicotine. However, their use does not lead to reduced risk of illness. The reduction of exposure to harmful substances cannot be expected when used in combination with cigarettes. Heated tobacco products and cigarettes have similar nicotine exposure levels and pharmacokinetics; thus, use of the former results in nicotine dependence and exacerbates the difficulty in discontinuing tobacco consumption. The popularity of heated tobacco products could adversely affect any of the six main measures of tobacco control.Conclusion Although public health concerns have been identified for the popularity of heated tobacco products, evidence remains insubstantial for the formulation of regulatory implications. Additional research is needed on the health effects to users and bystanders, effects on cigarettes use, and influence on tobacco control policy. From the perspective of the precautionary principle of public health, the same regulation as for cigarettes should be implemented as regards heated tobacco products until their health effects are fully elucidated.

INTRODUCTION: Despite the effectiveness of smoking cessation counseling, participation of nurses in delivering smoking cessation advice has been far from satisfactory in practice. Training nurses is considered to be important for increasing self-efficacy and skills for routine delivery of smoking cessation counseling. The aim of the present study was to evaluate the effectiveness of a smoking cessation educational program for Japanese nurses on subsequent changes of their behavior in delivering smoking cessation counseling, three months later. METHODS: We ran a 6-hour smoking cessation educational program for nurses recruited from the Nursing Associations of 13 prefectures in Japan between May 2019 and February 2020. Surveys were conducted by questionnaire before the start of the program and 3 months thereafter. The successful implementation of smoking cessation counseling behavior was evaluated according to the 5As of the Clinical Practice Guidelines for Treating Tobacco Use and Dependence (Ask, Advise, Assess, Assist, Arrange). RESULTS: We received 289 responses 3 months after the program finished (response rate 46.0%). At that time, 43% of participants had increased the frequency of 'Ask' and 42.1%, 50%, 39.3%, and 28.6%, respectively, had also increased their frequency of 'Advise', 'Assess', 'Assist', and 'Arrange'. We found that smoking cessation counseling was significantly more frequently delivered after the educational program for those participants who had routinely delivered 'Advise' before the program as measured by increased delivery of 'Assess' and 'Assist' afterwards (OR=2.39; 95% CI: 1.00-5.69, OR=2.54; 95% CI: 1.16-5.60 and OR=3.68; 95% CI: 1.40-9.65, OR=2.77; 95% CI: 1.10-7.01, respectively). CONCLUSIONS: The program successfully increased the frequency of nurses providing smoking cessation advice to patients. Readiness to deliver smoking cessation counseling before the program and continuing self-efficacy after the program are important for changing the behavior of nurses in delivering smoking cessation counseling.
RESUMO
The use of a biomarker is mandatory for quantitative analysis of exposure to secondhand smoke (SHS). This article summarizes urinary biomarkers of smoke exposure which can be now quantified. The most reliable urinary biomarkers to assess the exposure to SHS are NNAL 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and NNAL-Glucuronides, which is metabolites of tobacco-specific nitrosamine. These substances were detected even in 50% of children who had undetectable level of cotinine (<0.5 ng/ml). Urinary cotinine, which is determined by a highly sensitive competing enzyme immunoassay, is also a useful biomarker. However, individual variability of CYP2A6 allele,in which nicotine is catalyzed to cotinine, affects the level of urinary cotinine. Approximately 20% of Japanese subjects have homozygotes or heterozygotes of the CYP2A6*4 allele, which has impaired nicotine metabolism and subsequently may underestimate the actual exposure to SHS. In assessing the exposure to SHS, therefore, individual variability of CYP2A6 gene polymorphism should be taken into consideration. The combination of urinary cotinine measurement and self-report of parents' smoking seems to be accurate to assess the exposure to SHS in mass screening.

Tobacco smoking is the number one preventable cause of disease and death in China as it is globally. Indeed, the toll of smoking in China is much greater than its status as the world's most populous country. There is a persistent and continuing need for China to implement the measures specified in the global tobacco control treaty, the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC), which China ratified in 2005. The theme for the 2021 WHO World No Tobacco Day focuses on the need to support smoking cessation. This article presents findings from the International Tobacco Control (ITC) Policy Evaluation Project cohort surveys in China, in comparison to ITC cohort surveys in two neighboring countries: Japan and the Republic of Korea. These findings demonstrate that smokers in China very much want to quit, but these intentions are not being translated into quit attempts, relative to smokers in Japan and the Republic of Korea. Additionally, about 80% of Chinese smokers want the Chinese government to do more to control smoking. These findings reaffirm the need for China to implement strong, evidence-based measures to reduce smoking. The objective of Healthy China 2030 to reduce deaths from non-communicable diseases by 30% can be achieved by reducing smoking prevalence from its current 26.6% to 20%, and this reduction can be achieved through strong implementation of FCTC measures.
RESUMO
Japan is one of the world's largest cigarette markets and the top heated tobacco product (HTP) market. No forms of tobacco advertising, promotion, and sponsorship (TAPS) are banned under national law, although the industry has some voluntary TAPS restrictions. This study examines Japanese tobacco users' self-reported exposure to cigarette and HTP marketing through eight channels, as well as their support for TAPS bans. Data are from the 2018 ITC Japan Survey, a cohort survey of adult exclusive cigarette smokers (n = 3288), exclusive HTP users (n = 164), HTP-cigarette dual users (n = 549), and non-users (n = 614). Measures of overall average exposure to the eight channels of cigarette and HTP advertising were constructed to examine differences in exposure across user groups and products. Dual users reported the highest exposure to cigarette and HTP advertising. Tobacco users (those who used cigarettes, HTPs, or both) reported higher average exposure to HTP compared to cigarette advertising, however non-users reported higher average exposure to cigarette compared to HTP advertising. Retail stores where tobacco or HTPs are sold were the most prevalent channel for HTP and cigarette advertising, reported by 30-43% of non-users to 66-71% of dual users. Non-users reported similar exposure to cigarette advertising via television and newspapers/magazines as cigarette smokers and dual users; however, advertising via websites/social media was lower among non-users and HTP users than among cigarette smokers and dual users (p < 0.05). Most respondents supported a ban on cigarette (54%) and HTP (60%) product displays in stores, and cigarette advertising in stores (58%).

The market growth of heated tobacco products (HTPs), such as IQOS, Ploom TECH, and glo, has increased dramatically in Japan since 2016. Little is known about the reasons why current and former smokers are using HTPs. The data for this cross-sectional study were from the 2018 (Wave 1) International Tobacco Control (ITC) Japan Survey, a national web-based survey of 4500 people, including 658 current HTP users, of whom 549 were concurrently smoking cigarettes and 109 were former smokers. The most common reasons for regularly using HTPs were: beliefs that HTP are less harmful than cigarettes to themselves (90.6%) or to others (86.7%), enjoyment (76.5%), and social acceptability (74.4%). About half of current smokers (55.1%) reported using HTPs because these products might help them quit smoking. However, a near-equal percentage (52.0%) of current smokers reported using HTPs to replace some of the cigarettes they smoked so that they did not have to give up smoking altogether. If smokers are using HTPs to complement rather than quit their smoking, then the harm reduction potential of HTPs suggested by the toxicity studies will be diminished.

This paper describes the methods of the Wave 1 (2018) International Tobacco Control (ITC) Japan Survey. The respondents were adults aged 20 years and older in one of four user groups: (1) cigarette-only smokers who smoked at least monthly and used heated tobacco products (HTPs) not at all or less than weekly, (2) HTP-only users who used HTPs at least weekly and smoked cigarettes not at all or less than monthly, (3) cigarette-HTP dual users who smoked at least monthly and used HTPs at least weekly, and (4) non-users who had never smoked or who smoked less than monthly and used HTPs less than weekly. Eligible respondents were recruited by a commercial survey firm from its online panel. Respondents were allocated proportionally to sample strata based on demographic, geographic, and user type specifications benchmarked to a national reference. Survey weights, accounting for smoking/HTP use status, sex, age, education, and geography, were calibrated to benchmarks from a nationally representative survey in Japan. Response rate was 45.1% and cooperation rate was 96.3%. The total sample size was 4615 (3288 cigarette smokers, 164 exclusive HTP users, 549 cigarette-HTP dual users, and 614 non-users). The 2018 ITC Japan Survey sampling design and survey data collection methods will allow analyses to examine prospectively the use of cigarettes and HTPs in Japan and factors associated with the use of both products and of transitions between them.

Health warnings are an effective strategy for communicating the health harms of smoking, encouraging quitting, and preventing smoking initiation. This study examines the effectiveness of existing text-only health warnings, identifies key predictors of warning effectiveness, and assesses support for pictorial warnings in Japan. Data are from the 2018 International Tobacco Control (ITC) Japan Survey, a cohort survey of adult cigarette smokers (n = 3306), dual users of cigarettes and heated tobacco products (n = 555), and non-cigarette smokers (n = 823). Weighted multivariable logistic regression models were used to assess predictors of warning effectiveness and support for pictorial warnings. Overall, 15.6% of respondents noticed warnings, and 7.9% read or looked closely at warnings. Overall, 10.3% of smokers and dual users said the warnings stopped them from having a cigarette, and 7.2% avoided warnings. Overall, 27.5% of respondents said the warnings made them think about health risks of smoking, but only 2.7% of smokers and dual users said the warnings made them more likely to quit. Overall, 57.6% of respondents supported pictorial warnings. The weak effectiveness of Japan's text-only warnings is consistent with that in other countries with similar warnings. There is majority support for pictorial warnings in Japan, although the level of support is lower than in other countries.

Comprehensive smoke-free policies such as those called for by the WHO FCTC are the only way to protect the public effectively from the harms of secondhand smoke (SHS), yet Japan has been slow to implement this important health measure. This study examines baseline levels of smoking and SHS exposure in public places and support for smoking bans in Japan prior to the implementation of the 2018 national smoke-free law. Data are from the International Tobacco Control (ITC) Japan Wave 1 Survey (Feb-Mar 2018), a web survey of adult cigarette smokers, heated tobacco product users, dual users, and non-users (total N = 4684). Measures included prevalence of smoking (whether respondents noticed people smoking inside restaurants and bars at their last visit, and workplaces in the last month), and support for complete smoking bans in these venues. Smoking prevalence in each venue was high overall in 2018 (49% of workplaces, 55% of restaurants, and 83% of bars), even higher than in China, the country with the greatest toll of SHS. Support for complete smoking bans was very high overall (81% for workplaces, 78% for restaurants, and 65% for bars). Non-users were less likely to be exposed to SHS and had higher support for smoking bans than tobacco users. These findings point to the ineffectiveness of partial smoke-free laws in Japan and reinforce the call for comprehensive smoke-free laws, which even smokers would support at higher levels than in many other ITC countries.

In Japan, the tobacco industry promotes heated tobacco products (HTPs) as a reduced-risk tobacco product. This study examines: (1) smokers' harm perceptions of HTPs relative to combustible cigarettes; (2) differences in relative harm perceptions between exclusive smokers and smokers who use HTPs (concurrent users) and between concurrent users based on frequency of product use; and (3) if smokers who were exposed to HTP advertising hold beliefs that are consistent with marketing messages of lower harmfulness. This cross-sectional study included 2614 adult exclusive cigarette smokers and 986 concurrent users who reported their perceptions of harmfulness of HTPs compared to cigarettes, as well as their exposure to HTP advertising in the last six months. Among all smokers, 47.5% perceive that HTPs are less harmful than cigarettes, 24.6% perceive HTPs to be equally as harmful, 1.8% perceive HTPs as more harmful, and 26.1% did not know. Concurrent users are more likely than exclusive smokers to believe that HTPs are less harmful (62.1% versus 43.8%, p < 0.0001) and less likely to report that they did not know (14.3% versus 29.4%, p < 0.0001). Frequent HTP users are more likely than infrequent users to believe that HTPs are less harmful (71.7% versus 57.1%, p ≤ 0.001). Believing that HTPs are less harmful than cigarettes was associated with noticing HTP advertising on TV (p = 0.0005), in newspapers/magazines (p = 0.0001), on posters/billboards (p < 0.0001), in stores where tobacco (p < 0.0001) or where HTPs (p < 0.0001) are sold, on social media (p < 0.0001), or in bars/pubs (p = 0.04). HTP users were significantly more likely than non-HTP users to believe that HTPs are less harmful than cigarettes, with this belief being more prominent among frequent users. Smokers who have been exposed to HTP advertising were more likely to perceive HTPs as less harmful than cigarettes.

Use of heated tobacco products (HTPs) among current smokers is becoming increasingly popular in Japan. This study aims to compare characteristics and tobacco-related behaviors among concurrent users of HTPs and combustible cigarettes (n = 644) with exclusive smokers (n = 3194) or exclusive HTP users (n = 164). The secondary aim was to explore heterogeneity within concurrent use subgroups. Data were from Wave 1 of the ITC Japan Survey, a nationally representative web survey conducted from February to March 2018. Concurrent cigarette-HTP users were younger and wealthier than exclusive smokers. However, there were no difference in the frequency of smoking, number of cigarettes per day, and smoking cessation behaviors between the two groups, suggesting that HTPs reinforce nicotine dependence. Compared to exclusive HTP users, concurrent cigarette-HTP users reported higher frequency of non-daily HTP use, and lower number of tobacco-containing inserts per day. Almost all concurrent cigarette-HTP users smoked every day (93.9%); 48.4% both smoked and used HTPs daily (dual daily users, n = 396), while 45.5% were daily smokers and non-daily HTP users (predominant smokers, n = 213). Concurrent user subgroups differed from each other on age, tobacco use behaviors, and quit intention. Alongside heterogeneity between concurrent and exclusive product users, differences across concurrent use subgroups highlight the importance of considering frequency of use in characterizing poly-tobacco users.

Heated tobacco products (HTPs), such as IQOS, glo, and Ploom TECH, with a variety of flavored tobacco-containing inserts, have reportedly achieved a significant market share in Japan. We analyzed data from Wave 1 of the ITC Japan Survey, a nationally representative web survey conducted in February to March 2018 among 4684 adult participants to estimate the prevalence of HTP use, describe characteristics of HTP users, and explore user preferences for HTP device and flavor. The overall prevalence of monthly HTP use was 2.7% (1.7% daily use). Virtually all HTP users were current cigarette smokers (67.8%) or former smokers (25.0%); only 1.0% of HTP users were never smokers. Among HTP users, IQOS was the most frequently reported brand used (64.5%), and menthol was the most common flavor reported (41.5%). IQOS was used more by younger respondents and those who reported daily use, while Ploom TECH was more popular among older respondents and non-daily HTP users. This is one of the first non-industry funded studies to explore the use of HTPs in Japan.

Although heated tobacco products (HTPs) have become increasingly popular in Japan, little is known about whether these emerging tobacco products are being used within indoor public spaces. Nationally representative data were obtained prior to implementation of a comprehensive smoke-free law in Japan as part of Wave 1 of the International Tobacco Control Japan Survey (February-March 2018). We estimated the weighted prevalence of HTP use within indoor public spaces among tobacco users and compared these to estimates for combustible cigarettes (CCs). Overall, 15.6% of current tobacco users in Japan declared that they used HTPs within indoor public spaces. Any HTP use within indoor public spaces was significantly lower than any CC use (80.1% vs. 96.7%). Dual HTP + CC users reported using CCs more frequently than using HTPs within indoor public spaces (97.7% vs. 76.0%). In conclusion, HTP use is less common than CC use within indoor public spaces. Findings of this study can inform the development of targeted smoke-free policies to benefit public health.

BACKGROUND: It has been reported that there is an inverse association between osteoarthritis (OA) and osteoporosis. However, the relationship of bone mass to OA in a Japanese population whose rates of OA are different from Caucasians remains uncertain. METHODS: We studied the association of appendicular bone mineral density (second metacarpal; mBMD) and quantitative bone ultrasound (calcaneus; stiffness index) with knee and hand OA among 567 Japanese community-dwelling women. Knee and hand radiographs were scored for OA using Kellgren-Lawrence (K/L) scales. In addition, we evaluated the presence of osteophytes and of joint space narrowing. The hand joints were examined at the distal and proximal interphalangeal (DIP, PIP) and first metacarpophalangeal/carpometacarpal (MCP/CMC) joints. RESULTS: After adjusting for age and body mass index (BMI), stiffness index was significantly higher in women with K/L scale, grade 3 at CMC/MCP joint compared with those with no OA. Adjusted means of stiffness index and mBMD were significantly higher in women with definite osteophytes at the CMC/MCP joint compared to those without osteophytes, whereas there were no significant differences for knee, DIP and PIP joints. Stiffness index, but not mBMD, was higher in women with definite joint space narrowing at the CMC/MCP joint compared with those with no joint space narrowing. CONCLUSIONS: Appendicular bone mass was increased with OA at the CMC/MCP joint, especially among women with osteophytes. Our findings suggest that the association of peripheral bone mass with OA for knee, DIP or PIP may be less clearcut in Japanese women than in other populations.
RESUMO
Trends of cancer mortality in Japan were reviewed in comparison with all-cause mortality, by major sites and age groups. The proportion of cancer mortality to all-cause mortality is on the increase among young children, and the middle-aged population, due to the decreased mortality other than cancer. The number of deaths from cancer is still on the increase, mainly due to the aging population. But the age-standardized rates now seem to be leveling off among males and bottoming out for females. The trends are not simple, because the cancer mortality has been influenced by many factors such as the rapidly aging population or the drastic change in the social situation after World War II. In lung or liver cancer, the apparent birth cohort effect was observed; there were birth cohorts suggested to have lower or higher cancer mortality. Such birth cohort effects were related to the trends in strong risk factor such as tobacco smoking or hepatitis virus, and thus may influence the trends of cancer mortality. Therefore, on estimating the future trends of cancer mortality in Japan, it is important to take into account such trends in risk factors.

Kanagawa Prefecture became the first subnational government in Japan to implement an ordinance for the prevention of exposure to secondhand-smoke in public facilities. The ordinance aims to protect people from the negative health impacts of secondhand smoke; however, it has wide exemptions especially for hospitality and leisure business establishments. In addition, designated smoking areas are allowed in all public facilities, in contravention of the WHO Framework Convention on Tobacco Control. Nevertheless, its rapid enactment benefited from the political leadership of the governor as well as intensive communication between the government and a wide range of stakeholders in Kanagawa and beyond. The smoke-free efforts of Kanagawa could facilitate smoke-free action by other subnational and national governments for healthier environments.

OBJECTIVES: This study analysed 112 municipalities enforcing municipal smoking restrictions on streets in Japan to examine anti-smoking measures implemented in urban settings from a health perspective and derive lessons for future tobacco control. METHODS: Municipal governments implementing ordinances which restrict smoking on streets were identified through grey literature review. Implementation period, characteristics, scope, and department responsible were examined. RESULTS: Since the first municipal regulation was introduced in 1997, many other municipalities have followed. Enforcement of fines started in 2002, which is now a common practice nationwide. Nevertheless, the health impact of exposure to secondhand smoke is not clearly articulated in the ordinances. Street smoking bans have been developed in connection with "beautification" and littering prevention for environmental purposes, and local health departments do not have responsibility for these ordinances. CONCLUSIONS: There is potential to further prevent secondhand smoke exposure if such measures are expanded to indoor environments and integrated into broader policies. For policy-makers and advocates, the Japanese experience provides information on an additional tobacco control intervention as well as clues in the process of design, implementation and enforcement of such municipal measures. A more comprehensive and health-driven approach is required to effectively address the harm of secondhand smoke in Japan.
