A Mask Detection Algorithm Based on Improved Yolov5s

Aiming at the severe form of new coronavirus epidemic prevention and control, a target detection algorithm is proposed to detect whether masks are worn in public places. The Ghostnet and SElayer modules with fewer design parameters replace the BottleneckCSP part in the original Yolov5s network, which reduces the computational complexity of the model and improves the detection accuracy. The bounding box regression loss function DIOU is optimized, the DGIOU loss function is used for bounding box regression, and the center coordinate distance between the two bounding boxes is considered to achieve a better convergence effect. In the feature pyramid, the depthwise separable convolution DW is used to replace the ordinary convolution, which further reduces the amount of parameters and reduces the loss of feature information caused by multiple convolutions. The experimental results show that compared with the yolov5s algorithm, the proposed method improves the mAP by 4.6% and the detection rate by 10.7 frame/s in the mask wearing detection. Compared with other mainstream algorithms, the improved yolov5s algorithm has better generalization ability and practicability. © 2022 ACM.

The Effect of Primary School Education on Preventive Behaviours during COVID-19 in Japan

Education plays a critical role in promoting preventive behaviours against the spread of pandemics. In Japan, handwashing education in primary schools was positively correlated with preventive behaviours against COVID-19 transmission for adults in 2020, during the early stages of COVID-19. The following year, the Tokyo Olympics were held in Japan, and a state of emergency was declared several times. Public perceptions of and risks associated with the pandemic changed drastically with the emergence of COVID-19 vaccines. We re-examined whether the effect of handwashing education on preventive behaviours persisted by covering a longer period of the COVID-19 pandemic than previous studies. A total of 26 surveys were conducted nearly once a month for 30 months from March 2020 (the early stage of COVID-19) to September 2022 in Japan. By corresponding with the same individuals across surveys, we comprehensively gathered data on preventive behaviours during this period. In addition, we asked about the handwashing education they had received in their primary school. We used the data to investigate how and to what degree school education is associated with pandemic-mitigating preventive behaviours. We found that handwashing education in primary school is positively associated with behaviours such as handwashing and mask wearing as a COVID-19 preventive measure but not related to staying at home. We observed a statistically significant difference in handwashing between adults who received childhood handwashing education and those who did not. This difference persisted throughout the study period. In comparison, the difference in mask wearing between the two groups was smaller but still statistically significant. Furthermore, there was no difference in staying at home between them. Childhood hygiene education has resulted in individuals engaging in handwashing and mask wearing to cope with COVID-19. Individuals can form sustainable development-related habits through childhood education.

What is behind the mask? Social representation of mask wearing

Background: During the COVID-19 pandemic, a preventive and widely mandatory use of face masks was a dominant segment of the infection prevention and control of the epidemic. Covering about 60-70% of the facial surface, face masks dramatically affect social interactions-especially emotion recognition, expression and mentalization. Difficulties in communication in the doctor-patient relationship become of paramount importance to the effectiveness of the healing work. This becomes even more critical when the patient suffers from a disorder characterized by a mentalization deficit. In our study, we use the theory of social representations to examine the contents with which mask wearing has become part of our everyday knowledge. Objectives: We aimed to explore the social representations of mask wearing considering its impact on interpersonal communication, in groups where the effectiveness of mutual understanding is critical. Methods: In our study, carried out during the second and third waves of the coronavirus epidemic in Hungary, we gave a free association task to the target word mask-wearing" in a group of medical doctors, and hospitalized somatic and psychiatric patients and healthy controls (total of 81 subjects, mean age 43.1 [13.83] years), then used the obtained associations to form semantic categories and to map the structure of social representations within the groups using a rank-frequency method. Results: The positive experience of safety and the negative experience of physiological discomfort caused by the facemasks were consistently central to the social representations of mask-wearing in all study groups. Differences were found between groups in terms of more mature elaborative categories, as well as anxiety, aggression, helplessness, damaged dependency needs, and forced conformity. Conclusions: The analysis of the social representations revealed ambivalent meanings of the mask wearing. Although there were significant differences in the structure of mask-related social representations, the mask was recognized as an "inconvenient but necessary" health protection measure in most of the groups studied. Based on the results, each group may be at risk in a different way or deal differently with the pandemic based on their specific representations.

Why resist?: opposition to mask-wearing during the Covid-19 pandemic in Greece

This study investigates the factors that might have affected the implementation of the mask-wearing measure in Greek society from March 2020 to November 2021. To do so, this study utilizes a critical review of dominant characteristics of modern Greek society followed by a systematic review of the most recent literature on mask-wearing attitudes. The data in this study is derived from official Greek governmental announcements regarding the mask-wearing measure during the pandemic and the depiction of attitudes towards mask-wearing through Greek digital media, including digital newspapers, informative magazines and websites, and digital news sites. The article argues that the main preventive factors relate to distrust towards authority, including specific identified barriers according to relevant literature. More importantly, this study reinforces the significance of the adequate appreciation of the historical, cultural and social context within which political measures are implemented regardless of their global scale and universal necessity.

Fostering mask-wearing with virality metrics and social media literacy: evidence from the U.S. and Korea.

Although social media can pose threats to the public health by spreading misinformation and causing confusion, they can also provide wider access to health information and opportunities for health surveillance. The current study investigates the ways in which preventive health behaviors and norms can be promoted on social media by analyzing data from surveys and experiments conducted in the U.S. and South Korea. Survey results suggest that the pathway from social media use for COVID-19 information to mask-wearing behavior through mask-wearing norms emerges only among individuals with strong perceived social media literacy in the U.S. Experimental findings show that wear-a-mask campaign posts on social media foster mask-wearing norms and behavioral intention when they come with large (vs. small) virality metrics (e.g., Likes, shares) in both the U.S. and South Korea. Additionally, American users are more willing to engage with posts that come with supportive (vs. mixed) comments by Liking, sharing and commenting. The results highlight the need to cultivate social media literacy and opportunities for exploiting social media virality metrics for promoting public health norms and behaviors.

Intellectual humility predicts COVID-19 preventive practices through greater adoption of data-driven information and feelings of responsibility

Preventive health practices have been crucial to mitigating viral spread during the COVID-19 pandemic. In two studies, we examined whether intellectual humility-openness to one's existing knowledge being inaccurate-related to greater engagement in preventive health practices (social distancing, handwashing, mask-wearing). In Study 1, we found that intellectually humble people were more likely to engage in COVID-19 preventive practices. Additionally, this link was driven by intellectually humble people's tendency to adopt information from data-driven sources (e.g., medical experts) and greater feelings of responsibility over the outcomes of COVID-19. In Study 2, we found support for these relationships over time (2 weeks). Additionally, Study 2 showed that the link between intellectual humility and preventive practices was driven by a greater tendency to adopt data-driven information when encountering it, rather than actively seeking out such information. These findings reveal the promising role of intellectual humility in making well-informed decisions during public health crises.

A Cross-Cultural Study of Mask-Wearing During the Covid-19 Pandemic: Comparing China, Japan and the USA

During the Covid-19 epidemic, Japanese and Chinese have overwhelmingly tended to wear face masks, while Americans have not. Why? In this paper, based on ethnographic interviews with members of these three societies as well as examination of mass media and scholarly reports, I provide a preliminary interpretation of this question.I first consider social psychologists' large-scale analyses of collectivism versus individualism;China and Japan are both considered to be collectivistic societies, whereas the United States is considered to be individualistic. I also consider ethnic belonging to one's nation in China and Japan, as opposed to civic belonging to one's nation in the United States. These explications have value in understanding Covid-19 policies but seem of limited use in explaining mask-wearing. For such understanding, I turn to ethnographic interviews - some twenty in each society - as well as participant-observation in public sites.My findings are these: While in Japan social pressure is paramount in leading to mask wearing, with the state mostly absent, in China state pressure is paramount, with social pressure largely absent. In the United States, with social pressure absent beyond one's sub-group and state pressure hotly contested, mask-wearing becomes a matter of politically-based individual choice. In these three societies, there have thus been different axes as to why mask-wearing is accepted or contested. This research is of too small a scale to fully explicate these factors;but it does show how anthropological analysis is essential in combining with the findings of other disciplines such as social psychology to arrive at a fuller understanding of contemporary social phenomena.

The influence of gain-loss framing and its interaction with political ideology on social distancing and mask wearing compliance during the COVID-19 pandemic.

The COVID-19 pandemic has caused millions of cases and over half a million deaths in the United States. While health experts urge citizens to adopt preventative measures such as social distancing and wearing a mask, these recommended behaviors are not always followed by the public. To find a way to promote preventative measures, the present study examined the role of gain-loss framing of COVID-19 related messages on social distancing and mask wearing compliance. Moreover, the study also tested potential moderating effects on framing with three individual characteristics: political ideology, subjective numeracy, and risk attitude. A sample of 375 U.S. adult residents were recruited from Amazon Mechanical Turk. Each participant read either a gain or loss-framed message related to practicing protective behaviors during the COVID-19 pandemic. Participants also completed scales of preventative behaviors, risk attitude, subjective numeracy, political ideology, and other demographic variables. It was found that those who were more liberal, risk-averse and had greater subjective numeracy were more likely to wear a mask and/or follow social distancing. Furthermore, in the presence of demographic and psychological factors, the study found participants in the loss-framed condition than in the gain-framed condition were more likely to adopt both preventative measures, supporting the notion of loss aversion. Additionally, the framing effect was also moderated by political ideology on mask-wearing, with the effect being stronger in liberals than in conservatives. Collectively, the study implies message framing may be a useful means to promote preventative measures in the current pandemic.

When do people increase COVID-19 protective behaviors? A longitudinal analysis of the impact of infections among close contacts and in the community.

Studies examining individual-level changes in protective behaviors over time in association with community-level infection and self or close-contact infection with SARS-CoV-2 are limited. We analyzed overall and demographic specific week-to-week changes in COVID-19 protective behaviors and their association with COVID-19 infections (regional case counts and self or close contacts). Data were collected through 37 consecutive weekly surveys from 10/17/2021 - 6/26/2022. Our survey panel included 212 individuals living or working in St. Louis City and County, Missouri, U.S.A. Frequency of mask-wearing, handwashing, physical distancing, and avoiding large gatherings was self-reported (more/the same/less than the prior week). Close contact with COVID-19 was reported if the panel member, their household member, or their close contact tested positive, got sick, or was hospitalized for COVID-19 in the prior week. Regional weekly COVID-19 case counts were matched to the closest survey administration date. We used generalized linear mixed models to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations. Evidence for effect modification was assessed using the likelihood ratio test. Increased protective behaviors were positively associated with COVID-19 case counts (ORhighest vs. lowest case count category = 4.39, 95% CI 3.35-5.74) and with participant-reported self or close contacts with COVID-19 (OR = 5.10, 95% CI 3.88-6.70). Stronger associations were found for White vs. Black panel members (p <.0001). Individuals modulated their protective behaviors in association with regional COVID-19 case counts and self or close contact infection. Rapid reporting and widespread public awareness of infectious disease rates may help reduce transmission during a pandemic by increasing protective behaviors.

Influence of setting-dependent contacts and protective behaviours on asymptomatic SARS-CoV-2 infection amongst members of a UK university.

We survey 62 users of a university asymptomatic SARS-CoV-2 testing service on details of their activities, protective behaviours and contacts in the 7 days prior to receiving a positive or negative SARS-CoV-2 PCR test result in the period October 2020-March 2021. The resulting data set is novel in capturing very detailed social contact history linked to asymptomatic disease status during a period of significant restriction on social activities. We use this data to explore 3 questions: (i) Did participation in university activities enhance infection risk? (ii) How do contact definitions rank in their ability to explain test outcome during periods of social restrictions? (iii) Do patterns in the protective behaviours help explain discrepancies between the explanatory performance of different contact measures? We classify activities into settings and use Bayesian logistic regression to model test outcome, computing posterior model probabilities to compare the performance of models adopting different contact definitions. Associations between protective behaviours, participant characteristics and setting are explored at the level of individual activities using multiple correspondence analysis (MCA). We find that participation in air travel or non-university work activities was associated with a positive asymptomatic SARS-CoV-2 PCR test, in contrast to participation in research and teaching settings. Intriguingly, logistic regression models with binary measures of contact in a setting performed better than more traditional contact numbers or person contact hours (PCH). The MCA indicates that patterns of protective behaviours vary between setting, in a manner which may help explain the preference for any participation as a contact measure. We conclude that linked PCR testing and social contact data can in principle be used to test the utility of contact definitions, and the investigation of contact definitions in larger linked studies is warranted to ensure contact data can capture environmental and social factors influencing transmission risk.

To wear or not to wear? The influence of regulatory focus and individual cultural orientation on face mask wearing

During the COVID-19 pandemic, much focus has been placed on the healthcare benefits of wearing face masks, yet some people resist wearing them. Though mask mandates may enhance face mask adoption in the short run, the effectiveness of such mandates, in the long run, remains questionable. Thus, understanding of psychological and sociological mechanisms behind wearing face masks becomes pertinent. This study by examining these underlying mechanisms, tends to answer two research questions: (1) How does regulatory focus impact one's behavior to wear face masks? (2) How does the impact of regulatory focus on this behavior vary under different cultural orientations? Drawing on the theory of regulatory fit, we found that people with a prevention focus will have fewer concerns about wearing face masks than people with a promotion focus. In addition, we also found that prevention-focused people who exhibited a cultural orientation with higher levels of collectivism, masculinity, power distance, and uncertainty avoidance had fewer concerns about face mask wearing perception and were more likely to wear face masks than did promotion-focused people with the same cultural orientation. The implications of these findings on the relevant literature and practice are also discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Why do people wear a mask? A replication of previous studies and examination of two research questions in a Japanese sample

Wearing masks is an easy and effective way to prevent infection by COVID-19. In Japan, two studies investigated the reasons why people wear a mask;however, the results were inconsistent. Therefore, the present study reexamined the association between mask wearing and the reasons given for doing so, focusing on the differences in and problems of item wording. The results of both studies were found to be almost reproducible, and there were few issues regarding item wording. Furthermore, the results revealed that people wear a mask to prevent them selves and others from infection and to conform to others wearing a mask. We suggest that inconsistencies in the results were due to differences in item wording, and discuss how future research should be conducted.

Should we wear a mask? Household assessment of mask wearing for COVID-19 in Ya'an, China

In late 2019 and 2020, the novel SARS-CoV-2 virus spread worldwide and resulted in the COVID-19 pandemic, the second deadliest pandemic in modern history since the 1918 influenza pandemic. Since the virus was novel, no therapeutics and vaccines existed. Effective implementation of non-pharmaceutical interventions was essential to reducing the transmission of the disease until the discovery of effective therapeutics and vaccines. This study explores the influence of the facilitating protective action attribute on adopting mask-wearing as a protective action in Ya'an, Sichuan Province, China. The study found that perceptions of mask effectiveness to reduce the probability of contracting and spreading the disease, positive social influences, and the influence of an alert emotion shaped the facilitating protective action attribute and the adoption of mask-wearing during the COVID-19 pandemic. The research also revealed a significant positive correlation between the expected consequences from contracting COVID-19, the influence of both the alert and positive emotions, and information sources on the adoption of mask-wearing as a protective action. Lastly, expected consequences from exposure, indirectly affected by age, and information from authorities directly affected the adoption of the recommended protective action. The significance of both expected consequences and information from authorities affected the adoption of the recommended action. The finding suggested what actions public health, public policy, and emergency management leadership can take to enhance the effectiveness of non-pharmaceutical interventions to mitigate the spread of disease during future pandemics.

The Role of Vaccination and Face Mask Wearing on COVID-19 Infection and Hospitalization: A Cross-Sectional Study of the MENA Region.

Since the emergence of the Coronavirus disease (COVID-19) pandemic, the disease has affected more than 675 million people worldwide, including more than 6.87 million deaths. To mitigate the effects of this pandemic, many countries established control measures to contain its spread. Their riposte was based on a combination of pharmaceutical (vaccination) and non-pharmaceutical (such as facemask wearing, social distancing, and quarantine) measures. In this way, cross-sectional research was conducted in Algeria from 23 December 2021 to 12 March 2022 to investigate the effectiveness of preventative interventions in lowering COVID-19 infection and severity. More specifically, we investigated the link between mask-wearing and infection on one side, and the relationship between vaccination and the risk of hospitalization on the other. For this purpose, we used binary logistic regression modeling that allows learning the role of mask-wearing and vaccination in a heterogeneous society with respect to compliance with barrier measures. This study determined that wearing a mask is equally important for people of all ages. Further, findings revealed that the risk of infection was 0.79 times lower among those who were using masks (odds ratio (OR) = 0.79; confidence interval (CI) 95% = 0.668-0.936; p-value = 0.006). At the same time, vaccination is a necessary preventive measure as the risk of hospitalization increases with age. Compared with those who did not get vaccinated, those who got vaccinated were 0.429 times less likely to end up in the hospital (OR = 0.429; CI95% = 0.273-0.676; p < 0.0001). The model performance demonstrates significant relationships between the dependent and independent variables, with the absence of over-dispersion in both studied models, such as the Akaike Information Criterion (AIC) scores. These findings emphasize the significance of preventative measures and immunization in the battle against the COVID-19 pandemic.

Covid-19 Control: Face Mask Detection Using Deep Learning for Balanced and Unbalanced Dataset

Facemask wearing is becoming a norm in our daily lives to curb the spread of Covid-19. Ensuring facemasks are worn correctly is a topic of concern worldwide. It could go beyond manual human control and enforcement, leading to the spread of this deadly virus and many cases globally. The main aim of wearing a facemask is to curtail the spread of the covid-19 virus, but the biggest concern of most deep learning research is about who is wearing the mask or not, and not who is incorrectly wearing the facemask while the main objective of mask wearing is to prevent the spread of the covid-19 virus. This paper compares three state-of-the- art object detection approaches: Haarcascade, Multi-task Cascaded Convolutional Networks (MTCNN), and You Only Look Once version 4 (YOLOv4) to classify who is wearing a mask, who is not wearing a mask, and most importantly, who is incorrectly wearing the mask in a real-time video stream using FPS as a benchmark to select the best model. Yolov4 got about 40 Frame Per Seconds (FPS), outperforming Haarcascade with 16 and MTCNN with 1.4. YOLOv4 was later used to compare the two datasets using Intersection over Union (IoU) and mean Average Precision (mAP) as a comparative measure;dataset2 (balanced dataset) performed better than dataset1 (unbalanced dataset). Yolov4 model on dataset2 mapped and detected images of masks worn incorrectly with one correct class label rather than giving them two label classes with uncertainty in dataset1, this work shows the advantage of having a balanced dataset for accuracy. This work would help decrease human interference in enforcing the COVID-19 face mask rules and create awareness for people who do not comply with the facemask policy of wearing it correctly. Hence, significantly reducing the spread of COVID-19.

The role of perceived level of threat, reactance proneness, political orientation, and coronavirus salience on health behavior intentions.

OBJECTIVE: This pre-registered study was designed to test whether reminders of death and coronavirus would have similar or different effects on health behavior intentions concerning COVID-19 (e.g., mask wearing, social distancing) and whether the type of framing of these behaviors would moderate these effects. DESIGN: The study utilized a 3 (threat: mortality salience vs. coronavirus reminder vs. control topic) x 3 (framing: autonomy-supportive vs. controlled vs. neutral) design. Measures of perceived threat of COVID-19, reactance proneness, and political orientation were included as individual differences. RESULTS: Although the interaction between threat and framing conditions was not significant, the data revealed that (1) lower perceived threat of COVID-19 was associated with lower health behavior intentions to reduce the spread of the virus; (2) after an induction to express their thoughts and feelings about COVID-19, participants with low perceived threat of COVID-19 significantly increased their health intentions; (3) perceived threat of COVID-19 moderated the relationship between reactance proneness and health intentions, such that those high in reactance proneness reported lower intentions unless they had high perceptions of threat; and (4) politically conservative participants reported lower intentions to engage in healthy behaviors, and this relationship was mediated by their lower perceived threat of COVID-19.

The Relationship Between Face Mask Use and Face-Touching Frequency in Public Areas: Naturalistic Study.

BACKGROUND: Throughout the COVID-19 pandemic in the United States, a major public health goal has been reducing the spread of the virus, with particular emphasis on reducing transmission from person to person. Frequent face touching can transmit viral particles from one infected person and subsequently infect others in a public area. This raises an important concern about the use of face masks and their relationship with face-touching behaviors. One concern discussed during the pandemic is that wearing a mask, and different types of masks, could increase face touching because there is a need to remove the mask to smoke, drink, eat, etc. To date, there have been few studies that have assessed this relationship between mask wearing and the frequency of face touching relative to face-touching behaviors. OBJECTIVE: This study aimed to compare the frequency of face touching in people wearing a mask versus not wearing a mask in high-foot traffic urban outdoor areas. The purpose of this study was to assess if mask wearing was associated with increased face touching. METHODS: Public webcam videos from 4 different cities in New York, New Jersey, Louisiana, and Florida were used to collect data. Face touches were recorded as pedestrians passed under the webcam. Adult pedestrians wearing masks were compared to those not wearing masks. Quantitative measures of frequency, duration, site of touch, and oral activities were recorded. Linear regression analysis was used to assess the association between mask use and face touching. RESULTS: Of the 490 observed subjects, 241 (49.2%) were wearing a mask properly and 249 (50.8%) were not. In the unmasked group, 33.7% (84/249) were wearing it improperly, covering the mouth only. Face touching occurred in 11.4% (56/490) of the masked group and 17.6% (88/490) in the unmasked group. Of those who touched their face, 61.1% (88/144) of people were not wearing a mask. The most common site of face touching was the perioral region in both groups. Both the masked and unmasked group had a frequency of face touching for 0.03 touches/s. Oral activities such as eating or smoking increased face touching in the unmasked group. CONCLUSIONS: Contrary to expectations, non-mask-wearing subjects touched their face more frequently than those who were wearing a mask. This finding is substantial because wearing a face mask had a negative association with face touching. When wearing a mask, individuals are less likely to be spreading and ingesting viral particles. Therefore, wearing a mask is more effective in preventing the spread of viral particles.

Behavioral changes of preventive activities of influenza among children in satellite cities of a metropolitan area of Tokyo, Japan, by the COVID-19 pandemic.

OBJECTIVE: In children in a metropolitan area of Tokyo, Japan, behavioral change and influenza infection associated with the frequency of nonpharmaceutical interventions (NPI) was assessed from the 2018-2019 season (Preseason) and the 2020-2021 season (coronavirus disease 2019 [COVID-19] season). METHODS: We conducted an exclusive survey among children attending preschool, elementary school, and junior high school in the Toda and Warabi regions, Japan, during the 2018-2019 (Preseason, distributed via mail) and 2020-2021 seasons (COVID-19 season, conducted online). The proportion of preventive activities (hand washing, face mask-wearing, and vaccination) was compared in the Preseason with that of the COVID-19 season. The multivariate logistic regression model was further applied to calculate the adjusted odds ratio (AOR) with 95% confidence intervals (CIs) for influenza infection associated with NPI frequency (hand washing and face mask wearing) in each Preseason and COVID-19 season. RESULTS: The proportion of vaccinated children who carried out hand washing and face mask wearing was remarkably higher during the COVID-19 season (48.8%) than in the Preseason (18.2%). A significant influenza infection reduction was observed among children who washed hands and wore face masks simultaneously (AOR, 0.87; 95% CI, 0.76-0.99; P = 0.033). CONCLUSIONS: A strong interest and performance in the intensive measures for the prevention of influenza under the COVID-19 pandemic was demonstrated. Positive association was observed from a combination of NPI, hand washing, and face mask-wearing and influenza infection. This study's findings could help in activities or preventive measures against influenza and other communicable diseases in children.

Psychosocial Factors Predict Mask-Wearing: A Longitudinal Study Across 3 Phases of the COVID-19 Pandemic.

Determinants of mask-wearing during a pandemic range from the personal to the political. Using a repeated measures design, we examined psychosocial predictors of self-reported mask-wearing 3 times during the early stage of the COVID-19 pandemic. Participants completed surveys at baseline (summer 2020), 3 months (fall 2020), and 6 months (winter 2020-2021). The survey assessed the frequency of mask-wearing and psychosocial predictors from various theories, including fear of COVID-19, perceived severity, perceived susceptibility, attitude, health locus of control, and self-efficacy. Results indicated that the strongest predictors of mask-wearing varied as a function of the stage in the pandemic. In the earliest phase, fear of COVID-19 and perceived severity were the strongest predictors. Three months later, attitude was the strongest predictor. Finally, another 3 months later, self-efficacy became the strongest predictor. Overall, the results suggest that the primary determinants of a novel protective behavior shift over time and with increased familiarity.

The association between tobacco or nicotine product use behaviors and non-compliance with mask wearing in COVID-19 pandemic period.

Objectives: It is necessary to investigate tobacco or nicotine product(TNP) use which acts as a risk factor for COVID-19 infection. Especially, mask wearing is difficult to practice when using TNP. Therefore, this study aimed to examine the association between TNP use behaviors and non-compliance with mask wearing in COVID-19 pandemic. Methods: The samples of 208,618 Korean adults aged 19 years or older were used. As an independent variable, TNP use behaviors such as TNP use status, changes in TNP use after COVID-19, TNP types, and attempt to quit were used. Logistic regression was performed on sex-stratified participants. Results: Among men, Odds ratio(OR) of current TNP users was 2.00(95%CI [1.66, 2.40]), and OR of former users was 1.32[1.09, 1.60] compared to never users. In women, OR was 1.50[1.00-2.26] for former users. Cigarette use was more associated with not wearing a mask than NCTNP use (OR=1.53[1.12, 2.08]). Men whose TNP use decreased had lower non-compliance (OR=0.52[0.36, 0.74]). Women whose TNP use increased had lower non-compliance (OR= 0.13[0.07, 0.26]). Conclusion: Current and former users were less likely to wear masks. Cigarette use was more associated with not wearing a mask than non-cigarette tobacco or nicotine products(NCTNP) use. Changes in TNP use showed association, but in opposite direction for men and women. Therefore, we suggest that more attention should be paid to TNP use prevention and cessation support during the epidemic of respiratory infectious diseases. In addition, it is necessary to identify risk factors of cigarette users in compliance with mask wearing.
