Understanding Physical Distancing and Face Mask Use Across High-Risk African American Subgroups During the COVID-19 Pandemic: Application of Health Belief Model.

Physical distancing and face masks remain frontline prevention strategies due to suboptimal vaccine uptake and the highly infectious COVID-19 variants. Communities of color are disproportionately impacted by a chronic disease burden that places them at higher risk of severe COVID-19 disease. Therefore, they can greatly benefit from face mask use and physical distancing, especially if the individual(s) have not received the vaccine. We applied the Health Belief Model to explore barriers and motivators influencing physical distancing and face mask use among high-risk, Black American subgroups during the early COVID-19 pandemic stages. We conducted 62 semi-structured interviews among four Black American subgroups: young adults, individuals with underlying medical conditions, essential workers, and parents. Thematic analysis, guided by the Health Belief Model, yielded six themes: (1) Knowledge on Face Mask Use and Physical Distancing, (2) Perceived Susceptibility and Severity Varies by Subgroup, (3) Experience with and Perceived Self-Efficacy to Engage in Preventive Behavior, (4) Perceived Benefits to engaging in preventive behaviors, (5) Perceived Barriers to engage in preventive behaviors, and (6) Cues to action to increase participation. Each subgroup's unique experience informed multilevel, tailored approaches that can be used by health promotion practitioners to improve face mask use and physical distancing among uniquely vulnerable Black American subgroups in the current and future pandemic.

Universal use of face mask for the prevention of the spread of COVID-19 in community settings in a South-western State of Nigeria: willingness and barriers.

BACKGROUND AND OBJECTIVES: One of the major drivers of the novel coronavirus (SARS-CoV-2) pandemic is community transmission. Nigeria, like other countries globally, took to strict preventive public health measures including good respiratory and hand hygiene, physical distancing, and the use of face mask to control the spread of COVID-19 disease. Furthermore, the government of Lagos State in Nigeria made a pronouncement on the universal use of face mask in the community. While the use of face masks has proven to be an effective barrier to the transmission of respiratory diseases, its use in the community is uncommon. This study assessed the willingness and compliance with wearing face masks for the reduction of the community spread of COVID-19 and identified possible barriers to use of mask among residents in Lagos State. METHODS: This was a descriptive cross-sectional study, that surveyed 552 respondents who were adult residents of Lagos State. Data collection was quantitative, using a pretested, interviewer-administered questionnaire, and findings were presented in frequencies and percentages. Pearson's chi-square and logistic regression analyses were used to test the association between variables. The level of significance was set at 5%. RESULTS: A majority (75.7%) of the respondents were willing to wear a face mask in public areas but only 21.9% of the respondents were willing to wear a mask at all times. The most identified barriers to wearing mask were discomfort (72.5%) and inconvenience (77.7%). Two-thirds of the respondents reported they were compliant with always wearing a face mask when leaving home. Only 15.0% of the respondents wore the mask continuously and appropriately, covering the nose and mouth. Having a post-secondary education and being older (40 years and above) were found to be positive predictors of both willingness to wear a mask and compliance with universal mask policy (wearing masks continuously and appropriately). CONCLUSION: Our findings suggest that willingness to wear a face mask influences compliance, and that having a post-secondary education and being older (> 40 years) were positive predictors of both willingness to wear a mask and compliance with universal mask policy (wearing it continuously and correctly). The major barriers to wearing masks were discomfort and inconvenience. Effective risk communication strategies to reach diverse groups for better compliance with public health measures are urgently needed even for the future.

Face Mask Use and Associated Factors Among Students: Mixed Methods Study.

BACKGROUND: COVID-19 has gravely affected the world, including students, due to the high level of contracting infections. OBJECTIVE: This study assessed the magnitude of mask use and associated factors among students. METHODS: A cross-sectional study using mixed methods was conducted among students at Gambella Teachers' Education and Health Science College, Gambella Region, Southwest Ethiopia, from March 5 to March 30, 2021. The stratified random sampling technique was used. Proportional allocation of samples was used to randomly select case teams, and a simple random sampling technique was used to recruit the students. The data were collected by trained and experienced enumerators. Data were entered into EpiData (version 3.1; EpiData Association) and exported to SPSS (version 22; IBM Corp) for analysis. Logistic regression was executed. The adjusted odds ratio (AOR) with the 95% CI was used to determine the association and strength with the outcome variable. The qualitative data were transcribed, translated, coded, and analyzed using thematic analysis. Then, the themes were used to triangulate the quantitative study. RESULTS: The study included a total of 379 participants and yielded a response rate of 95.5% (379/397). The majority of study participants were older than 25 years, with the mean age being 26.34 (SD 5.8) years. This study found that the magnitude of mask use among students was 87% (330/379). The odds of mask use were higher among students who were female (AOR 3.32, 95% CI 1.191-9.248), younger (AOR 2.55, 95% CI 1.155-5.627), agreed that not all persons with COVID-19 develop severe disease (AOR 3.38, 95% CI 1.36-8.41), agreed that there is currently no effective cure (AOR 6.28, 95% CI 1.36-28.99), performed proper washing with soap and water (AOR 0.027, 95% CI 0.004-0.182), had started to stay home (AOR 0.168, 95% CI 0.054-0.52), agreed that COVID-19 is fatal (AOR 0.236, 95% CI 0.084-0.666), agreed that a flu vaccine is sufficient for COVID-19 prevention (AOR 3.874, 95% CI 1.540-9.749), and disinfected equipment and working areas at least once a day (AOR 0.222, 95% CI 0.086-0.575). CONCLUSIONS: This study found that the magnitude of mask use among students was relatively moderate in Ethiopia. Sex, age, agreeing that not all persons with COVID-19 develop severe disease, agreeing that there is currently no effective cure, performing proper washing with soap and water, starting to stay home, agreeing that COVID-19 is fatal, and agreeing that the flu vaccine is sufficient to prevent COVID-19 were independently associated with mask use among students. Therefore, colleges should aggressively encourage students to wear masks and monitor the implementation of COVID-19 prevention regulations along with the accessibility of masks.

Knowledge and Practice of Personal Protective Measures Against COVID-19 in Africa: Systematic Review.

BACKGROUND: With COVID-19 being a newly evolving disease, its response measures largely depend on the practice of and compliance with personal protective measures (PPMs). OBJECTIVE: This systematic review aimed to examine the knowledge and practice of COVID-19 PPMs in African countries as documented in the published literature. METHODS: A systematic search was conducted on the Scopus, PubMed, and Web of Science databases using appropriate keywords and predefined eligibility criteria for the selection of relevant studies. Only population-based original research studies (including qualitative, quantitative, and mixed methods studies) conducted in Africa and published in the English language were included. The screening process and data extraction were performed according to a preregistered protocol in PROSPERO (CRD42022355101) and followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. Thematic analysis was used to systematically summarize the studies into 4 predefined domains: knowledge and perception of PPMs, mask use, social and physical distancing, and handwashing and hand hygiene, including their respective levels and associated factors. RESULTS: A total of 58 studies across 12 African countries were included, published between 2019 and 2022. African communities, including various population groups, had varying levels of knowledge and practice of COVID-19 PPMs, with the lack of personal protective equipment (mainly face masks) and side effects (among health care workers) being the major reasons for poor compliance. Lower rates of handwashing and hand hygiene were particularly noted in several African countries, especially among low-income urban and slum dwellers, with the main barrier being the lack of safe and clean water. Various cognitive (knowledge and perception), sociodemographic, and economic factors were associated with the practice of COVID-19 PPMs. Moreover, there were evident research inequalities at the regional level, with East Africa contributing 36% (21/58) of the studies, West Africa contributing 21% (12/58), North Africa contributing 17% (10/58), Southern Africa contributing 7% (4/58), and no single-country study from Central Africa. Nonetheless, the overall quality of the included studies was generally good as they satisfied most of the quality assessment criteria. CONCLUSIONS: There is a need to enhance local capacity to produce and supply personal protective equipment. Consideration of various cognitive, demographic, and socioeconomic differences, with extra focus on the most vulnerable, is crucial for inclusive and more effective strategies against the pandemic. Moreover, more focus and involvement in community behavioral research are needed to fully understand and address the dynamics of the current pandemic in Africa.

The Effect of Mask Use on the Ocular Surface During the COVID-19 Pandemic.

Objectives: The new coronavirus disease 2019 (COVID-19) pandemic emerged in Wuhan, China in October 2019 and spread rapidly all over the world, making extended mask use an inescapable rule of daily life. Literature data indicate that the use of face masks increases the symptoms of dry eye in addition to preventing the spread of COVID-19. The aim of our study was to evaluate the relationship between the clinical signs and symptoms of dry eye and the duration of mask use in healthy individuals using regular face masks. Materials and Methods: Thirty-five patients aged 20-60 years with no additional ophthalmologic pathology were included in the study. Participants were stratified by duration of face mask use: ≤6 hours/day (group 1) and >6 hours/day (group 2). The patients were assessed with the Ocular Surface Disease Index (OSDI) questionnaire, fluorescein ocular surface staining, and tear break-up time (TBUT) to evaluate the effect of extended mask use on the ocular surface. Results: A total of 62 eyes of 35 patients, 20 women (57.1%) and 15 men (42.9%), were included in the study. The two mask use duration groups had similar OSDI values (p=0.736). When the ocular surface staining pattern was examined according to the Oxford scale, 50% (10/20) of the eyes in group 1 were assessed as stage 1 and the other 10 eyes as stage 0. In group 2, 47.6% (20/42) of the eyes were assessed as grade 1, 11.9% (5/42) as grade 2, and 4.7% (2/42) as grade 3. Conclusion: Prolonged face mask use was shown to cause decreased TBUT and increased ocular surface staining even in healthy individuals. Further studies are needed to investigate changes in the tear film after extended daily mask use.

Face Mask Use and Social Distancing Attitude of Healthcare Students: A Multi-Disciplinary Study.

This multi-disciplinary, cross-sectional, and descriptive study investigated health care students' face mask use knowledge, attitude, and practices (KAP) and social distancing attitudes. The study was carried out from October to December 2021 and surveyed 543 health care students selected via convenience sampling from the three Shaqra University campuses in Saudi Arabia. Standard multiple linear regressions were conducted on face mask use KAP and social distancing attitude to identify their significant associated factors. The students in this study had poor knowledge and a neutral attitude towards and modest use practices of face masks during the COVID-19 pandemic. Being female, being a nursing student, and having greater self-reported COVID-19-prevention knowledge were related to higher levels of face mask use knowledge. Having higher face mask use knowledge was linked to better attitude and practice. Knowledge of COVID-19 and its prevention and decreased COVID-19 risk perception were associated with better face mask use practices. The students had more positive than negative attitudes toward social distancing. Having known someone who was infected by the virus, lower risk perception, and better face mask use practices were associated with more positive social distancing attitudes. The findings imply the need to ensure that future health care practitioners are knowledgeable, have a positive attitude and good practices concerning face mask use, and have positive attitudes toward social distancing. The study implications are relevant for health care education in Saudi Arabia and elsewhere.

High rates of observed face mask use at Colorado universities align with students' opinions about masking and support the safety and viability of in-person higher education during the COVID-19 pandemic.

BACKGROUND: Over the course of the COVID-19 pandemic, colleges and universities have focused on creating policies, such as mask mandates, to minimize COVID-19 transmission both on their campuses and in the surrounding community. Adherence to and opinions about these policies remain largely unknown. METHODS: The Centers for Disease Control and Prevention (CDC) developed a cross-sectional study, the Mask Adherence and Surveillance at Colleges and Universities Project (MASCUP!), to objectively and inconspicuously measure rates of mask use at institutes of higher education via direct observation. From February 15 through April 11, 2021 the University of Colorado Boulder (CU, n = 2,808 observations) and Colorado State University Fort Collins (CSU, n = 3,225 observations) participated in MASCUP! along with 52 other institutes of higher education (n = 100,353 observations) spanning 21 states and the District of Columbia. Mask use was mandatory at both Colorado universities and student surveys were administered to assess student beliefs and attitudes. RESULTS: We found that 91.7%, 93.4%, and 90.8% of persons observed at indoor locations on campus wore a mask correctly at University of Colorado, Colorado State University, and across the 52 other schools, respectively. Student responses to questions about masking were in line with these observed rates of mask use where 92.9% of respondents at CU and 89.8% at CSU believe that wearing masks can protect the health of others. Both Colorado universities saw their largest surges in COVID-19 cases in the fall of 2020, with markedly lower case counts during the mask observation window in the spring of 2021. CONCLUSION: High levels of mask use at Colorado's two largest campuses aligned with rates observed at other institutes across the country. These high rates of use, coupled with positive student attitudes about mask use, demonstrate that masks were widely accepted and may have contributed to reduced COVID-19 case counts. This study supports an emerging body of literature substantiating masks as an effective, low-cost measure to reduce disease transmission and establishes masking (with proper education and promotion) as a viable tactic to reduce respiratory disease transmission on college campuses.

Association of face mask use with self-reported cardiovascular symptoms during the COVID-19 pandemic.

Introduction: Countries are mandating the use of face masks to stem the spread of coronavirus disease 2019 (COVID-19). Face mask use has been associated with discomfort due to its effects on thermoregulation, breathing and oxygenation. We evaluated the prevalence and severity of self-reported cardiovascular symptoms before and during face mask use. Methods: This was a cross-sectional study of 1,001 participants residing in Singapore, who participated in a self-administered questionnaire between 25 April 2020 and 4 May 2020. Symptom severity before and during mask use, and health-seeking behaviour information were collected. The study outcome was self-reported worsening of cardiovascular symptoms and its association with the type of mask worn, duration of mask worn per day, and intensity of physical activities during mask use. Results: The most common symptom reported during mask use was dyspnoea. Independent predictors for self-reported cardiovascular symptoms during mask use were moderate-high physical activity during mask use (odds ratio [OR] 1.634, 95% confidence interval [CI] 1.176-2.270, P = 0.003), duration of mask use for ≥3 h (OR 1.672, 95% CI 1.189-2.352, P = 0.003) and type of mask used, after adjusting for age, sex, healthcare-based worker status and presence of comorbidities. N95 mask was associated with worse symptoms when compared to surgical mask. Participants with ≥3 worsening symptoms or worsening dyspnoea, palpitations, fatigue and dizziness were more likely to seek medical help. Conclusion: Face mask use has been proven to be an effective way in curbing COVID-19 transmission. However, participants in this study had concerns regarding its use and these concerns should be urgently addressed to enable mask use policies to be enacted.

Estimated Mask Use and Temporal Relationship to COVID-19 Epidemiology of Black Lives Matter Protests in 12 Cities.

BACKGROUND: There is an increased risk of SARS-CoV-2 transmission during mass gatherings and a risk of asymptomatic infection. We aimed to estimate the use of masks during Black Lives Matter (BLM) protests and whether these protests increased the risk of COVID-19. Two reviewers screened 496 protest images for mask use, with high inter-rater reliability. Protest intensity, use of tear gas, government control measures, and testing rates were estimated in 12 cities. A correlation analysis was conducted to assess the potential effect of mask use and other measures, adjusting for testing rates, on COVID-19 epidemiology 4 weeks (two incubation periods) post-protests. Mask use ranged from 69 to 96% across protests. There was no increase in the incidence of COVID-19 post-protest in 11 cities. After adjusting for testing rates, only Miami, which involved use of tear gas and had high protest intensity, showed a clear increase in COVID-19 after one incubation period post-protest. No significant correlation was found between incidence and protest factors. Our study showed that protests in most cities studied did not increase COVID-19 incidence in 2020, and a high level of mask use was seen. The absence of an epidemic surge within two incubation periods of a protest is indicative that the protests did not have a major influence on epidemic activity, except in Miami. With the globally circulating highly transmissible Alpha, Delta, and Omicron variants, layered interventions such as mandated mask use, physical distancing, testing, and vaccination should be applied for mass gatherings in the future.

Collective health behavior and face mask utilization during the COVID-19 pandemic in Oklahoma, USA.

BACKGROUND: Face mask use offers an important public health tool for reducing the spread of coronavirus disease 2019 (COVID-19), yet the politicization of COVID-19 has resulted in uneven adherence. This study assesses the effects of setting characteristics and the sociodemographic composition of crowds on group-level masking rates. METHODS: We conducted 123 site observations of masking behavior at public locations across Oklahoma (USA) between June and September 2020. We used analyses of variance and t-tests to examine variation in masking and ordinary least squares regression to model the effect of setting and sociodemographic characteristics on site-level masking rates. RESULTS: The masking rate across all sites averaged 34% but varied widely. Site-level masking rates were higher at metropolitan sites and sites with a store or municipal masking mandate. The masking rate at sites where women or older adults (60+) were the predominant group did not differ significantly from other sites. Ethnically diverse sites exhibited significantly higher masking rates compared with predominantly white sites. Findings indicate that setting characteristics explained a greater amount of variation in collective masking rates than sociodemographic differences. CONCLUSIONS: This study underscores the importance of place and policy for mask adherence. In the absence of state-level mandates, masking policies at a more local level may be effective.

Association between self-reported masking behavior and SARS-CoV-2 infection wanes from Pre-Delta to Omicron-predominant periods - North Carolina COVID-19 Community Research Partnership (NC-CCRP).

BACKGROUND: Wearing a face mask is a primary public health method to reduce SARS-CoV-2 transmission. METHODS: We performed a nested case-control analysis within the North Carolina COVID-19 Community Research Partnership (NC-CCRP) of adults who completed daily surveillance surveys, April 2020 - February 2022. We assessed the association between self-reported mask wearing behavior during nonhousehold interactions and COVID-19 infection during 3 pandemic periods using conditional logistic regression models of risk of infection that were adjusted for demographics, vaccination status, and recent known exposure to COVID-19. RESULTS: Among 3,901 cases and 27,813 date-matched controls, there was a significant interaction between mask use and time period (P < .001). Prior to July 2021, the odds of a reported infection were 66% higher (aOR = 1.66, 95% CI = 1.43-1.91) among participants reporting ≥1 day not wearing a mask compared to those who reported no days (1,592 cases, 11,717 controls). During the Delta-predominant period, the results were similar (aOR = 1.53, 95% CI = 1.23-1.89; 659 cases, 4,649 controls). This association was attenuated during the Omicron-predominant period, where odds of an infection was 16% higher (aOR = 1.16, 95% CI = 1.03-1.32; 1,563 cases, 10,960 controls). CONCLUSIONS: While the effect of not wearing a mask remains significant, during the Omicron-predominant period we observed a decrease in the association between self-reported mask wearing and risk of SARS-CoV-2 infection.

Attitudes toward the use of facemasks during the COVID-19 pandemic in the Indian community.

Background: The use of face masks by all community members for the prevention of COVID-19 infection is considered one of the most effective strategies. However, the use of masks by community members was influenced by many factors which affected its efficacy as a preventive measure. Aim: To evaluate the attitudes toward the use of masks during the COVID-19 pandemic in the Indian community. Materials and Methods: We did an online survey with the help of a questionnaire which included information about demographic data, awareness and attitudes about COVID-19 infection and its preventive measures, and attitudes towards mask use in particular. Results: Participants had a positive attitude towards mask use. However, there were certain reasons for not using masks some of which were gender specific. Conclusion: People had good awareness and attitude towards mask use. However, some gender differences in perception of masks used in various settings should be addressed for future awareness and education of the community about mask use.

Socioeconomic correlates of face mask use among pedestrians during the COVID-19 pandemic: An ecological study.

Background: Many countries have recommended using face masks for the general population in public places to reduce the risk of COVID-19 transmission. This study aimed to assess the effects of socioeconomic status on face mask use among pedestrians during the COVID-19 pandemic. Methods: This cross-sectional study was conducted in Ahvaz, southwest Iran in August 2020. A total of 10,440 pedestrians have been studied from 92 neighborhoods of the city. Three socioeconomic indicators including Land price, Literacy rate, and the Employment rate for each neighborhood were used in this study. Analysis of Covariance and partial correlation coefficients were applied to assess the relationship between prevalence rates of mask usage and SES indicators. Results: The mean ± SD age of the pedestrians was 32.2 ± 15.1 years. Of 10,440 observed participants, 67.9% were male. The overall prevalence of face mask usage was 45.6%. The prevalence of mask usage in older people and women was significantly higher than the others. The three assessed socioeconomic indicators were directly correlated to the prevalence of mask usage at individual and neighborhood levels. Conclusion: We found that literacy had the strongest correlation with the prevalence of mask usage compared to the land price and employment rate among the three assessed SES indicators. Hence, it can be concluded that the social component of socioeconomic status has a greater effect on mask usage by people than the economic component of socioeconomic status.

Education-related inequalities in beliefs and behaviors pertaining to COVID-19 non-pharmaceutical interventions.

BACKGROUND: The coronavirus pandemic has exposed existing social inequalities in relation to disease preventive behaviors, risk of exposure, testing and healthcare access, and consequences as a result of illness and containment measures across different population groups. However, due to a lack of data, to date there has been limited evidence of the extent of such within-country inequalities globally. METHODS: We examined education-related inequalities in four COVID-19 prevention and testing indicators within 90 countries, using data from the University of Maryland Social Data Science Center Global COVID-19 Trends and Impact Survey, in partnership with Facebook, over the period 1 June 2021 to 31 December 2021. The overall level of education-related inequalities, as well as how they differ across country income groups and how they have changed over time were analyzed using the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII). We also assessed whether these education-related inequalities were associated with government policies and responses. RESULTS: Education-related inequalities in beliefs, mask wearing, social distancing and testing varied across the study countries. Mask wearing and beliefs in the effectiveness of social distancing and mask wearing were overall more common among people with a higher level of education. Even after controlling for other sociodemographic and health-related factors, social distancing practice was higher among the most educated in low/lower middle income countries, but was higher overall among the least educated in high income countries. Overall there were low education-related inequalities in COVID-19 testing, though there was variation across countries. CONCLUSIONS: The study highlights important within-country education-related differences in COVID-19 beliefs, preventive behaviors and testing, as well as differing trends across country income groups. This has implications for considering and targeting specific population groups when designing public health interventions and messaging during the COVID-19 pandemic and future health emergencies.

Mask Use for Athletes: A Systematic Review of Safety and Performance Outcomes.

CONTEXT: With the current Centers for Disease Control and Prevention recommendations for mask use to minimize transmission of coronavirus 2019 (COVID-19) coupled with concern for future pandemics that would require mask wearing, providing data-driven guidance with respect to athletic performance is essential. OBJECTIVE: The purpose of this study was to perform a systematic review of existing literature on the use of face masks while exercising to assess the physiologic effects of face masks worn during athletic activities. DATA SOURCES: A systematic review was conducted of studies on face mask use during exercise according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Potential studies were identified through searches of MEDLINE, Embase, Cochrane CENTRAL and CINAHL databases. STUDY SELECTION: Screening was completed independently by 2 coauthors who sought to identify studies that described the effects of oronasal mask use, if any, on sports/exercise/physical activity, for any age, gender, or level of sport. Articles describing mask effects without exercise, articles published before 1980, and non-English language studies were excluded. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 3. DATA EXTRACTION: Data extraction focused on physiologic parameters measured during physical activity performed while wearing a face mask. RESULTS: Twenty-two articles met all inclusion criteria. Study analysis revealed that the use of masks in healthy volunteers during exercise had no significant effect on physiologic parameters measured including heart rate (HR), respiratory rate (RR), oxygen saturation, and perceived exertion. Of the studies that investigated N95 masks in the healthy adult population, 2 reported modest changes in RR and maximum power output indicative of decreased athletic performance when subjects were exercising at maximum effort. Similar findings were seen in studies of subpopulations including children and pregnant women. CONCLUSION: Available data suggest that healthy individuals can perform moderate-to-vigorous exercise while wearing a face mask without experiencing changes in HR, RR, and oxygen saturation that would compromise individual safety or athletic performance. In the specific situation in which an N95 mask is worn, maximum power generated may be impaired. WHAT IS KNOWN ABOUT THE SUBJECT: To date, there has been no systematic review of the existing literature to provide a clear consensus on whether face mask use significantly impacts athletic performance. Mask use has been demonstrated safe in the workplace; however, the use of face masks during exercise has not been examined on a large scale, particularly with respect to physiologic parameters. WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE: This analysis highlights that available data suggest that healthy individuals can perform heavy exercise in face masks with minimal physiologic changes. This is the first systematic review of studies analyzing exercise use wearing masks. With the evidence presented here commonly cited concerns about both safety and performance decrements with mask use during physical activities may be allayed.

Self-reported mask use among persons with or without SARS CoV-2 vaccination -United States, December 2020-August 2021.

Wearing a facemask can help to decrease the transmission of COVID-19. We investigated self-reported mask use among subjects aged 18 years and older participating in the COVID-19 Community Research Partnership (CRP), a prospective longitudinal COVID-19 surveillance study in the mid-Atlantic and southeastern United States. We included those participants who completed ≥5 daily surveys each month from December 1, 2020 through August 31, 2021. Mask use was defined as self-reported use of a face mask or face covering on every interaction with others outside the household within a distance of less than 6 feet. Participants were considered vaccinated if they reported receiving ≥1 COVID-19 vaccine dose. Participants (n = 17,522) were 91% non-Hispanic White, 68% female, median age 57 years, 26% healthcare workers, with 95% self-reported receiving ≥1 COVID-19 vaccine dose through August 2021; mean daily survey response was 85%. Mask use was higher among vaccinated than unvaccinated participants across the study period, regardless of the month of the first dose. Mask use remained relatively stable from December 2020 through April (range 71-80% unvaccinated; 86-93% vaccinated) and declined in both groups beginning in mid-May 2021 to 34% and 42% respectively in June 2021; mask use increased again since July 2021. Mask use by all was lower during weekends and on Christmas and Easter, regardless of vaccination status. Independent predictors of higher mask use were vaccination, age ≥65 years, female sex, racial or ethnic minority group, and healthcare worker occupation, whereas a history of self-reported prior COVID-19 illness was associated with lower use.

Survey data of determinants related to Covid-19 preventive behaviors during the second waves in Indonesia using the reasoned action approach.

The dataset presented in this article examines preventive behaviors related to Covid-19 among Indonesians, i.e., wearing a mask, hand washing, and distancing, and its related determinants. Data collection was carried out when Indonesia was facing the second waves due to the rapid transmission of the Delta variant virus. The data assessing socio-demographic information, beliefs related to Covid-19 preventive behaviors based on the reasoned action approach, general beliefs about Covid-19, and Covid-19 preventive behaviors, from 18th June to 18th August 2021, gathering a total of 863 completed responses. The sampling technique in this online survey used a combination of purposive and snowball sampling methods to gather the participants via social media such as Instagram, Twitter, Facebook, and WhatsApp throughout Indonesia. The survey data were analyzed using frequency distributions and bivariate correlation analysis. The data will help to understand the psychosocial determinants of Covid-19 preventive behaviors and provide insight for the development of behavior change intervention to limit the spread of Covid-19 among Indonesians.
