RESUMO
OBJECTIVE: The hearing aid adoption rate among older adults in Japan is lower than that in other developed countries. Herein, a survey was conducted to identify this bottleneck and develop countermeasures. This study aimed to examine whether raising awareness of the relationship between hearing loss and dementia is significant for hearing tests and adopting hearing aids. METHODS: A questionnaire was administered to participants aged 65 or older who visited a general hospital to determine the background factors (1) for a recent history of hearing tests, (2) for the desire to visit an otolaryngologist and have a hearing test, (3) for recognizing the hearing loss-dementia relationship, and (4) for adopting hearing aids. RESULTS: A total of 517 patients (mean age, 78.06; SD 6.97), representing 2.4% of the region's older-adult population, participated in the survey. A history of hearing tests within five years was significantly associated with recognizing the hearing loss-dementia relationship (adjusted OR 2.36, 95% CI 1.49-3.72). The desire to visit an otolaryngologist or have a hearing test was significantly associated with recognizing the hearing loss-dementia relationship (adjusted OR 1.70, 95% CI 1.02-2.85). Moreover, 39.3% were aware of the hearing loss-dementia relationship. The significant associated factors were being female (OR 2.50, 95% CI 1.64-3.81) and having interpersonal hobbies (OR 1.66, 95% CI 1.11-2.49). The significant background factors for adopting hearing aids were older age (OR 6.95, 95% CI 1.90-25.40), self-reported severe hearing impairment (OR 5.49, 95% CI 2.55-11.80), and living alone (OR 2.63, 95% CI 1.18-5.89). Recognizing the hearing loss-dementia relationship was not a significant factor. CONCLUSION: Raising awareness of the hearing loss-dementia relationship was not associated with adopting hearing aids for self-reported hearing impairments. However, it may be associated with otolaryngology visits and hearing tests. Thus, steps like hearing screening for older adults are also essential.

Objective: This study estimated the percentage of mothers who received samples of breast milk substitutes at medical facilities and examined the relationship between receipt of the samples and breastfeeding practices in Japan. Methods: We used the data from the "The Japan COVID-19 and Society Internet Survey (JACSIS)" conducted in 2021. Two groups of mothers were analyzed: mothers 0-5 months postpartum (n = 1,412) and mothers 5-12 months postpartum (n = 2,045). Logistic regression analysis was conducted with the practice of exclusive breastfeeding as the dependent variable and the receipt of the sample as the explanatory variable. Exclusive breastfeeding was defined in different ways for each group: "exclusive breastfeeding under five months" as measured by 24-hour recall for mothers 0-5 months postpartum, and "exclusive breastfeeding for the first five months" as defined by asking mothers 5-12 months postpartum when they first fed infant formula or baby food and when they finished breastfeeding. Results: The proportion of mothers who received the samples was 82.4%. We found that mothers who received the samples were found to be less likely to continue "exclusive breastfeeding under five months" (odds ratio: 0.71, 95% confidence interval [CI]: 0.51-0.98). In addition, a similar trend was found in a subsample analysis restricted to mothers who intended to breastfeed during pregnancy (odds ratio: 0.62, 95% CI: 0.40-0.94). Conclusions: This study showed that more than 80% of mothers had received the samples of breast milk substitutes, and that receipt of the samples decreased the probability of their practicing exclusive breastfeeding. Regulating distribution of the samples at medical facilities is necessary to prevent interruptions of exclusive breastfeeding.
RESUMO
Introduction The global shift toward working from home due to the COVID-19 pandemic has led to concerns about increased sedentary behavior and its potential impact on work engagement, a critical factor for employee well-being and organizational productivity. This study aims to explore the association between sedentary time and work engagement among workers in Japan in the post-pandemic work environment. Methods This cross-sectional analysis utilized data from the Japan COVID-19 and Society Internet Survey (JACSIS), conducted from September to November 2023, after the COVID-19 pandemic period. Participants included employed individuals over 18 years, excluding those in domestic occupations. Sedentary time and work engagement were self-reported and categorized. Logistic regression analysis adjusted for confounders such as socioeconomic status, work characteristics, and mental and physical health was employed to explore this association. Results The study found a significant association between longer sedentary time and lower levels of work engagement. In particular, for desk workers, longer sedentary time was associated with lower work engagement (sedentary time, compared to the reference category "<4 hours/day", 4 to <8 h: OR 1.42, 95% CI: 1.25-1.60; 8 to <12 h: OR 1.77, 95% CI: 1.55-2.01; ≥12 h or unknown: OR 2.14, 95% CI: 1.80-2.51, respectively). Sensitivity analysis confirmed that these results are robust to different definitions of work engagement. Furthermore, analyses in subgroups of desk workers classified according to specific characteristics suggested that desk workers who are full-time workers in non-managerial positions and work from home ≥4 days per week were more strongly associated with prolonged sedentary behavior and low work engagement (in the group of full-time workers who were non-managers, sedentary time, compared to the reference category "<4 hours/day", 4 to <8 h: OR 2.14, 95% CI: 1.52-3.00; 8 to <12 h: OR 2.10, 95% CI: 1.46-3.00; ≥12 h or unknown: OR 3.32, 95% CI: 1.99-6.05; in those with work-from-home frequency of ≥4 days weekly, sedentary time, compared to the reference category "<4 hours/day", 4 to <8 h: OR 1.46, 95% CI: 0.99-2.16; 8 to <12 h: OR 1.73, 95% CI: 1.19-2.56; ≥12 h or unknown: OR 2.41, 95% CI: 1.58-3.67). Conclusions This study revealed a significant association between sedentary time and low work engagement among workers in Japan after the COVID-19 pandemic. In the future, prospective studies are needed to confirm the causal associations between the two, using more validated measures of sedentary behavior.
RESUMO
OBJECTIVE: Utility values enable relative comparisons across various health conditions, providing information for efficient allocation of healthcare resources. This study aimed to (1) quantify the utility values attributable to oral health-related quality of life (OHRQoL) in Japanese adults and (2) develop models for converting the 14-item Oral Health Impact Profile (OHIP-14) scores into EuroQoL 5-dimension 5-level (EQ-5D-5L)-based utility values. METHODS: This was a cross-sectional study. Data from a large-scale Internet survey of Japanese adults conducted in 2022 (n = 28 405; mean age 48.2 years) were analysed. Multiple linear regression models were fitted to investigate the association between OHIP-14 scores and EQ-5D-5L-based utility values, adjusting for confounders. Conversion models were developed using a random half of the participants, and the observed and predicted utility values in the other half were compared to evaluate the model performance. RESULTS: Among the participants, 55.2% scored 0, 20.9% scored 1-5 and 23.9% scored 6-56 on the OHIP-14, corresponding mean utility values of 0.93, 0.90 and 0.84, respectively. A one-point increase in the OHIP-14 score was associated with a lower utility value (coefficient: -0.0053; 95% confidence interval:health-related quality of life -0.0056, -0.0051). The estimated utility value attributable to OHIP-14 was -23.3 per 1000 individuals, greater than that for other prevalent chronic conditions, including hypertension and diabetes (-2.9 and -7.1 per 1000 individuals, respectively). The conversion model incorporated the OHIP-14 total score, age, sex and self-rated health, predicted utility scores on average and captured differences according to the number of teeth lost. However, there was a discrepancy between predicted and observed utility values in the lower utility value groups. CONCLUSION: OHRQoL substantially impacted utility values at the population level. The OHIP-14 holds the potential as a valuable tool for predicting average utility values based on oral health conditions; however, the prediction performance was relatively low for individuals with a lower health-related quality of life.
RESUMO
BACKGROUND: The decline in measles vaccination coverage is a global concern. In Japan, coverage of the first-dose of measles vaccine, which had exceeded the target of 95.0% since fiscal year (FY) 2010, fell to 93.5% in FY 2021. Vaccination coverage increased to 95.4% in FY 2022 but varied by municipality. Few studies have focused on regional disparities in measles vaccination coverage. This study aimed to clarify the regional disparities in measles vaccination coverage by municipality in Japan and their associated factors. METHODS: In this ecological study, the measles vaccination coverage in FY 2022; population density; area deprivation index (ADI, an indicator of socioeconomic status); proportion of foreign nationals, single-father households, single-mother households, and mothers aged ≥30 years; and number of medical facilities, pediatricians, and non-pediatric medical doctors in 1,698 municipalities were extracted from Japanese government statistics. Negative binomial regression was performed with the number of children vaccinated against measles as the dependent variable, number of children eligible for measles vaccination as the offset term, and other factors as independent variables. RESULTS: Vaccination coverage was less than 95.0% in 54.3% of municipalities. Vaccination coverage was significantly positively associated with population density and negatively associated with the proportion of single-father households, mothers aged ≥30 years, and the ADI (incidence rate ratio [IRR]: 1.004, 0.976, 0.999, 0.970, respectively). CONCLUSION: This study showed regional disparities in measles vaccination coverage in Japan. Single-father households, age of mothers, and socioeconomic status may be key factors when municipalities consider strategies to improve vaccination coverage.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) is a respiratory infection that considerably impacts both physical and mental health. In particular, the prolonged nature of psychological issues associated with COVID-19 has become a concern. However, evidence based on longitudinal studies investigating the changes in fear of COVID-19 has been limited, posing a public health challenge. METHODS: We investigated the predictors of changes in the Fear of COVID-19 Scale (FCV-19S) scores in the general Japanese population using data from a large-scale internet-based cohort study. RESULTS: We included 20,712 study participants (mean age = 51.1 years, percentage of males = 49.9%). The baseline FCV-19S score for the research participants was 17.0, and one year later, the FCV-19S score decreased to 15.8. The predictors of increase in FCV-19S scores were older age, male sex, COVID-19 requiring oxygen therapy, higher baseline FCV-19S total score, severe psychological distress, never married, worsening subjective health status, a greater number of COVID-19 vaccinations, a history of alcohol dependency, and living with family members. Conversely, the predictors of decrease in FCV-19S scores included habitual alcohol intake, COVID-19 not requiring oxygen therapy and a higher household income. Our study was an internet-based survey focused on residents of Japan, which raises the possibility of selection bias and makes it unclear whether the findings can be extrapolated to other countries and cultures. CONCLUSION: During the observation period, the FCV-19S scores significantly decreased. Severe COVID-19 requiring oxygen therapy within one year of baseline was the most impactful predictor of an increase in FCV-19S score. On the other hand, mild COVID-19 not requiring oxygen therapy was a predictor of a decrease in FCV-19S scores. Therefore, we believe that it is necessary to adopt individualized approaches stratified by the severity of the infection when addressing the fear of COVID-19.

OBJECTIVE: Although adverse childhood experiences (ACEs) are associated with poor health in adulthood, positive childhood experiences (PCEs) can reduce the risk of negative health outcomes. This study aimed to investigate whether PCEs in the community (CPCEs, ie, trusted adults other than parents, supportive friends, belongingness to school, or community traditions) would have an independent effect on better health outcomes and moderate the association between ACEs and adult illnesses. DESIGN: Cross-sectional survey. SETTING: Data were gathered from a nationwide, cross-sectional internet survey conducted in Japan in 2022. PARTICIPANTS: This study included 28 617 Japanese adults aged 18-82 years (51.1% female; mean age=48.1 years). PRIMARY AND SECONDARY OUTCOME MEASURES: The associations among self-reported ACEs, CPCEs before the age of 18 years and current chronic diseases (eg, cancer and depression) were investigated using multivariable logistic regression models. RESULTS: CPCEs were associated with lower odds of adult diseases (such as stroke, chronic obstructive pulmonary disease (COPD), chronic pain, depression, suicidal ideation and severe psychological distress) after adjusting for ACEs. More CPCEs weakened the association between ACEs and adult diseases. Specifically, among those with ACEs, ≥3 CPCEs (vs 0-2 CPCEs) lowered the adjusted prevalence by ≥50% for stroke (2.4% to 1.2%), COPD (2.2% to 0.7%) and severe psychological distress (16.4% to 7.4%). CONCLUSION: CPCEs could reduce ACE-related risk of poor physical and mental health in later life. Early-life interventions that enhance PCEs in schools and/or neighbourhoods are recommended.

OBJECTIVES: The COVID-19 pandemic has highlighted the long-term consequences of SARS-CoV-2 infection, termed long COVID. However, in the absence of comparative groups, the differentiation of disease progression remains difficult, as COVID-19 symptoms become indistinguishable from symptoms originating from alternative etiologies. This study aimed to longitudinally investigate the association between COVID-19 exposure and the somatic symptoms in the Japanese general population. DESIGN: This was a longitudinal cohort study with 1-year follow-up. SETTING AND PARTICIPANTS: Longitudinal data from 19 545 individuals who participated in the Japan Society and New Tobacco Internet Survey (JASTIS) 2022 and 2023 were included. In this study, we used data from the 2022 JASTIS as baseline data and the 2023 JASTIS as follow-up data. Based on questionnaire responses, respondents were classified into three categories of exposure to COVID-19. OUTCOME MEASURES: The somatic symptoms were assessed by the Somatic Symptom Scale-8 (SSS-8). Using generalised linear models adjusted for baseline covariates, we calculated the ORs of having very high somatic symptoms assessed by SSS-8, attributable to COVID-19 exposure (no COVID-19 cases as the reference group). RESULTS: Follow-up completers were divided into three groups according to COVID-19 exposure (no COVID-19, n=16 012; COVID-19 without O2 therapy, n=3201; COVID-19 with O2 therapy, n=332). After adjusting for all covariates, COVID-19 cases with O2 therapy had a significant positive association (OR 7.60, 95% CI 5.47 to 10.58) with a very high somatic symptoms burden while other COVID-19 exposure groups did not. Pre-existing physical and psychological conditions were also associated with increased risk of somatic symptoms. CONCLUSION: The findings of our study suggest that the severity of COVID-19 symptoms requiring O2 therapy in the acute phase led to high somatic symptoms. Pre-existing conditions were also associated with a subsequent risk of somatic symptoms.

There is limited information on whether the COVID-19 pandemic was associated with decreased breast cancer screening uptake and if COVID-19 vaccination was associated with an increase in screening uptake. Our study explored the uptake of breast cancer screening in Japan after the COVID-19 pandemic and assessed its association with the COVID-19 vaccination. We analyzed data from the Japan COVID-19 and Society Internet Survey (JACSIS), a web-based prospective cohort survey, and we included 6110 women without cancer history who were aged 40 to 74 years that participated in the 2012 and 2022 surveys. We examined the regular breast cancer screening uptake before and after the pandemic and employed a multivariable Poisson regression model to seek any association between COVID-19 vaccination and screening uptake. Of 6110, 38.2% regularly participated in screening before the pandemic and 46.9% did so after the pandemic. Individuals unvaccinated due to health reasons (incidence rate ratio (IRR) = 0.47, 95% CI: 0.29-0.77, p = 0.003) and for other reasons (IRR = 0.73, 95% CI: 0.62-0.86, p < 0.001) were less likely to undergo screening compared to fully vaccinated individuals. There was no long-term decrease in breast cancer screening uptake after the pandemic in Japan. Vaccination was linked to increased uptake, but there was no dose relationship.
RESUMO
The study aimed to examine the association of expanded adverse childhood experiences (ACEs) with psychological distress in adulthood. The data from nation-wide online cohort was used for analysis. Community dwelling adults in Japan were included. The ACEs was assessed by 15 items of ACE-J, including childhood poverty and school bullying. Severe psychological distress was determined as the score of Kessler 6 over 13. Multivariable logistic regression analysis was conducted, by using sample weighting. A total of 28,617 participants were analyzed. About 75% of Japanese people had one or more ACEs. The prevalence of those with ACEs over 4 was 14.7%. Those with ACEs over 4 showed adjusted odds ratio = 8.18 [95% CI 7.14-9.38] for severe psychological distress. The prevalence of childhood poverty was 29% for 50-64 year old participants and 40% of 65 or older participants. The impact of childhood poverty on psychological distress was less than other ACEs in these age cohorts. Bullying was experienced 21-27% in young generations, but 10% in 65 or older participants. However, the impact on psychological distress in adulthood was relatively high in all age groups. ACEs have impacted mental health for a long time. Future research and practice to reduce ACEs are encouraged.

BACKGROUND: To enhance tobacco control in Japan, the government set a future smoking rate target (smoking prevalence = 12% by 2022) arguing that the "smoking rate target is expected if only smokers who want to quit smoking now, actually quit". However, ideally both those wanting to quit now and those who wanted to in the past will succeed in the future. We aimed to re-define smokers who intend to quit and estimate their number. We also examined determinants of intention to quit, including daily tobacco consumption and tobacco use categories (exclusive combustible cigarette users, exclusive heated tobacco product (HTP) users, and dual (combustible cigarette and HTP)) users. METHODS: Using data from the 2021 Japan 'Society and New Tobacco' Internet Survey, we analyzed 5,072 current smokers (had used combustible cigarettes or HTPs in the past 30 days) aged 20-80 years. Smokers who intend to quit were defined as total smokers who want to quit now, have previously attempted or previously wanted to quit. Log-Poisson regression models were used to calculate adjusted odds ratios (aORs) with 95% confidence intervals (95%CI) for intention to quit (current or current/past), adjusting for potential covariates such as tobacco use categories. RESULTS: Among current smokers, 40.6% want to quit now, 27.0% have previously attempted and 9.0% have previously wanted to quit. Smokers of over 20 tobacco sticks/day are less likely to want to quit now than 1-10 /day (aOR = 0.79, 95%CI = 0.71-0.87) and less likely to intend to quit (both current and past) (aOR = 0.93, 95%CI = 0.88-0.98). Exclusive HTP and dual users were more likely to intend to quit (both current and past) than exclusive combustible cigarette users (aOR = 1.09, 95%CI = 1.04-1.14) and (aOR = 1.07, 95%CI = 1.03-1.12). CONCLUSIONS: In total, 76.6% of current smokers, were defined as having intention to quit (both current and past). Applying this percentage to the target calculation, Japan's smoking rate target would be 3.9%, considerably lower than the current target of 12%. The Japanese government may have to revise the smoking rate target. Additionally, we found that the usage of HTPs reduces intention to quit smoking. These insights have implications for setting of smoking rate targets and regulating HTPs in different countries.

BACKGROUND AND AIMS: Night-shift work disturbs sleep and is associated with poor health conditions among workers. We aimed to investigate the association between night-shift work and gambling among workers and the association between night-shift work and problem gambling in working and gambling participants. METHODS: This cross-sectional study used data from an online survey conducted between February 6 and 27, 2023 in Japan. A total of 21,134 workers participated in this study, including 9,739 respondents who had gambled in the past year. We estimated the association between night-shift work and gambling among workers and the association between night-shift work and problem gambling among those who gambled at the survey. We defined problem gambling as a score ≥ 8 on the Problem Gambling Severity Index. All estimates were weighted using a nationally representative survey in Japan. We fitted multivariable weighted logistic regression models after adjusting for 14 confounders. RESULTS: The weighted prevalence of gambling among non-night and night-shift workers was 42.1 % and 55.4 %, respectively. When focusing on workers gambling in the survey, the prevalence of problem gambling among non-night and night-shift workers was 8.8 % and 24.2 %, respectively. The weighted multivariable logistic regression analyses showed that night-shift work was associated with gambling participation among workers (adjusted odds ratio [aOR], 1.39, 95 % confidence interval [CI] 1.25-1.53, p < 0.001). In addition, night-shift work was associated with problem gambling among those who gambled (aOR 1.94, 95 % CI 1.57-2.40, p < 0.001). CONCLUSIONS: Night-shift work was associated with gambling among workers and with problem gambling among those who gambled.

Despite the acknowledged relationship between the usual (preferred) walking speed (UWS) and health, there is currently no practical method available to reliably and accurately detect slight changes in UWS. This study aimed to explore whether either of the following two phenomena occurs during continuous daily walking in various periods: (a) Similarity between the most frequent cadences in the two periods. (b) The occurrence of the most frequent cadence in at least one of the two periods during the other period, with a frequency close to that of the most frequent cadence. In August 2021, invitations to participate in the study were extended via email to participants that took part in the Japan COVID-19 and Society Internet Surveys (JACSIS). A mobile phone application that collected step data during continuous walking was provided to the participants, and data were collected from December 1, 2021, to January 31, 2022. While 1022 participants installed the phone application, only 505 had measurement data for ten days or more in each of the two months of the study duration. The cadence during continuous walking was automatically measured daily from 05:00 to 21:00. Most participants exhibited at least one of the phenomena mentioned above, confirming a common, notably frequent, invariant cadence over time. Overall, this method allows for the identification of minor reductions and lower bounds of decline in UWS. This study illustrates the potential for tracking a decreasing trend in UWS. Early detection of a downward trend permits individuals to take timely remedial action, as recovery is relatively easy, and the confirmation of even a slight recovery bolsters recovery motivation.
RESUMO
Various vaccinations are recommended for older adults; however, unlike childhood immunization programs, there is often no systematic immunization schedule for older adults, and management of the immunization schedule is the responsibility of the individuals. Self-managing immunization status can be challenging and potentially lead to missed vaccinations. This study aimed to describe the statuses and patterns of indicated vaccine uptake among older adults. This descriptive study utilized data from a large-scale nationwide internet survey in Japan (n = 6,828). Participants aged 65 years and older were asked about their immunization status for four vaccines in Japan: coronavirus disease 2019, influenza, pneumococcal, and herpes zoster vaccines. Overall, 6.8 % of the participants received all four vaccines, whereas 9.5 % had not received any of four vaccines. Many participants received one to three types of vaccinations (one type: 24.7 %, two types: 30.8 %, three types: 28.1 %). Attention should be focused on vaccine uptake among older adults.

BACKGROUND: Mother-to-infant bonding (MIB) is foundational for nurturing behaviors and an infant's development. Identifying risk factors for difficulties or problems in MIB is vital. However, traditional research often dichotomizes MIB using cutoff thresholds, overlooking its underlying complexities. This research utilizes latent profile analysis (LPA) to discern MIB subtypes in a nationwide Japanese dataset. METHODS: We conducted LPA on data from the Mother-to-Infant Bonding Scale (MIBS), collected from 3,877 postpartum women within one year of childbirth. To empirically validate the derived profiles, we examined their associated risk factors, focusing on sociodemographic, health, and perinatal variables. RESULTS: Four distinct MIB profiles emerged. Profile 1 indicated minimal difficulties, while Profile 4 exhibited severe multifaceted difficulties. Profiles 2 and 3 showed moderate difficulties distinguished by lack of positive affection and presence of negative affection (especially indifference), respectively. Compared to Profile 1, women in Profiles 2-4 had a higher likelihood of postpartum depression and low family support. Each profile also presented unique risk factors: medium family support in Profile 2, maternal working status in Profile 3, and pre-pregnancy underweight status in Profile 4. Notably, both Profiles 3 and 4 were also linked to increased feelings of loneliness since the onset of the COVID-19 pandemic. CONCLUSION: This study represents the first application of LPA to MIB, revealing distinct subtypes and their respective risk profiles. These insights promise to enhance and personalize early interventions for difficulties in MIB, affirming the necessity of acknowledging MIB's heterogeneity.
RESUMO
During the COVID-19 pandemic, people often modified their behaviors and performed individual infection control practices despite the uncertain effectiveness of these in preventing COVID-19. A cross-sectional study using a nationwide internet survey (Japan COVID-19 Society Internet Survey) was conducted from September 2022 through October 2022. The questionnaire consisted of individual-level social distancing behaviors and infection prevention measures, and COVID-19 vaccination status. A multivariate logistic regression was performed to determine factors associated with the diagnosis of COVID-19 in the last two months of the survey date. In total, 19,296 respondents were selected for the primary analysis. Of 19,296 respondents, those with COVID-19 diagnosed in the last two months were 1,909 (9.9%). Factors independently associated with a recent history of COVID-19 were meeting colleagues in person ⧠1 per week (adjusted odds ratio [aOR] 1.72). The response of "never or rarely" to the question of taking out (i.e., dining in) foods was marginally associated with a recent history of COVID-19 (aOR 1.27). Most individual, infection prevention practices and behavioral modifications during the omicron variant phase of the pandemic did not substantially impact COVID-19 prevention in the community.

INTRODUCTION: The global market of flavour capsule cigarettes (FCCs) has grown significantly over the past decade; however, prevalence data exist for only a few countries. This study examined prevalence and perceptions of FCCs among adults who smoke across five countries. METHODS: Cross-sectional data among adults who smoked cigarettes came from the International Tobacco Control Policy Evaluation Project Surveys-Brazil (2016/2017), Japan (2021), Republic of Korea (2021), Malaysia (2020) and Mexico (2021). FCCs use was measured based on reporting one's usual/current brand or favourite variety has flavour capsule(s). Perceptions of the harmfulness of one's usual brand versus other brands were compared between those who used capsules versus no capsules. Adjusted logistic regression models examined correlates of FCC use. RESULTS: There were substantial differences in the prevalence of FCC use among adults who smoke across the five countries: Mexico (50.3% in 2021), Republic of Korea (31.8% in 2021), Malaysia (26.5% in 2020), Japan (21.6% in 2021) and Brazil (6.7% in 2016/2017). Correlates of FCC use varied across countries. Capsule use was positively associated with being female in Japan and Mexico, younger age in Japan, Republic of Korea and Malaysia, high education in Brazil, Japan and Mexico, non-daily smoking in Republic of Korea, and having plans to quit in Japan and Republic of Korea. There was no consistent pattern of consumer perceptions of brand harmfulness. CONCLUSION: Our study documented the high prevalence of FCCs in some countries, pointing to the need to develop and implement regulatory strategies to control these attractive products.

Background: Most cancers are lifestyle-related and are thus preventable. Lifestyle habits can be improved by individual efforts; for example, because oral health is suggested to play a preventive role in cancer risk, toothbrushing is considered a critical and fundamental measure for controlling oral health. This study aimed to investigate the association between toothbrushing and cancer risk. Methods: Cross-sectional data from the Japan COVID-19 and Society Internet Survey, a large-scale (n = 32,000) online survey conducted in 2022, were used. From September 12 to October 19, 2022, questionnaires were distributed to candidates selected by simple random sampling from a Japanese Internet research company's panelists to represent the Japanese population. The association between toothbrushing and cancer risk according to cancer prevalence was then analyzed. Results: Among all 32,000 participants, 2,495 (7.8%) who had any cancer previously were analyzed. Multivariable logistic regression analysis revealed a significant association between toothbrushing habit and cancer risk. Conclusion: The findings of this study suggest that daily toothbrushing is essential for maintaining oral health and preventing cancer.
