Abstract

Introduction

The widespread use of face masks by the general public may help to prevent the spread of viruses. Face masks are thought to be a good strategy to protect against respiratory diseases such as the Coronavirus. Identifying student knowledge, attitude, and practice about the use of face masks is crucial to detect vulnerabilities and respond rapidly to avoid the spread of the infection. This study aimed to determine the knowledge, attitude, and practices of face mask utilization and associated factors in the COVID-19 pandemic among college students.

Methods

A cross-sectional study was performed from February to March 2021 among 764 students from Wachemo University, Southern Ethiopia. A multistage sampling technique was used in the study. The sample size for each department was allocated in proportion to the number of students in that department, and each respondent was chosen using a simple random sampling procedure. Data were collected using a pre-tested self-administered questionnaire and analyzed using SPSS version 26. To predict the relationship between the predictor and outcome variables, a logistic regression model was used. At a p-value of 0.05, statistical significance was declared.

Results

The study showed that the overall knowledge of the students was 223 (29.2%), their attitude was 673 (88.1%), and their practice was 684 (89.5%). The students from the college natural and computational sciences (AOR: 0.23; 95%CI: 0.13, 0.40) and students having good knowledge (AOR = 4.40; 95%CI; 2.13, 9.14) were found to be independently associated with face mask utilization.

Conclusion

When compared to other researches, the knowledge about the usage of face masks in this study was low, but the attitudes and practices were high. Authorities in areas that are in danger of a COVID-19 pandemic should plan and implement public awareness and education initiatives.

1. Introduction

Coronavirus disease (COVID-19) appeared as a new public health issue in Wuhan, China, with the public health problem that started in bats also spread to people via unknown intermediary species at the end of 2019 [1, 2]. High-grade fever, cough, sore throat, dyspnea, tiredness, and malaise were frequently observed symptoms in patients infected with the COVID-19 virus. The weaker immune systems of chronic disease patients and the elderly make the effects of COVID-19 more potent to them, which could result in death for those suffering from these comorbidities [1].

The disease has already spread to 219 countries around the world, prompting the World Health Organization (WHO) to declare it a pandemic. As of March 2021, there had been more than 120 million positive COVID-19 cases reported worldwide, with more than 2.5 million deaths and approximately 4 million vaccination doses provided [1, 3, 4].

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a virus that can infect persons of all ages and from all walks of life. It indiscriminately kills as it can affect healthy adults and people suffering from health problems, and it spreads swiftly at an exponential pace [1, 2]. The virus can be spread in two ways, namely, inhalation and contact with contaminated droplets. The incubation period for the disease varies from 2 to 14 days [1].

The disease could have major consequences in both developed and poor nations, where healthcare facilities and resources are inadequate; nevertheless, face coverings help to restrict the proliferation of COVID-19 [1, 57]. Preventive measures, which include the use of masks, hand hygiene, a physical distance of at least 1 meter, proper ventilation in indoor environments, monitoring, contact tracing, quarantine, isolation, and other infection prevention and control (IPC) measures, are all necessary to prevent SARS-CoV-2 transmission from person to person [79].

In collaboration with the government, health officials recommended that the public use face masks or coverings to reduce the risk of transmission, with authorities requiring their use in specific environments, such as public transportation, stores, schools (high, colleges, and universities), police stations, and other public places. Health officials have recommended that medical-grade face masks, such as respirators, be prioritized for use by medical personnel to prevent the shortage of supply for this product. Meanwhile, cotton masks are recommended for the public [8, 10, 11].

During the early stages of the pandemic, public health messages about wearing masks were inconsistent, conflicting, and tinged with contemptuous comments, which caused public discontent and even confusion. Eventually, the recommendations have evolved in lockstep with scientific understanding [8].

The widespread usage of face masks can help reduce virus transmission between individuals who are infected with the virus but have not yet acquired symptoms, as well as between individuals who do not have symptoms but are infected with the virus [1]. Ethiopia has substantially reversed course, aiming to achieve national and state records for new COVID-19 cases by September 2020. As of March 2021, Ethiopia had reported 181,869 confirmed cases and 2,602 deaths [3].

The World Health Organization has recommended that healthy persons wear masks indoors and outdoors for all students, employees, and tourists, with valid medical exemptions, when two meters of social distance cannot be maintained, since June 2020. In situations when physical isolation is problematic, non-medical masks are used to track the transmission of COVID-19 [3, 11, 12]. Many schools and universities require students to wear masks in public places and when they are within six feet of others [13].

Even if the study location is known to the investigators, there is little information about knowledge, attitudes, and practices face mask utilization among university students in Ethiopia. Therefore, this study was aimed to determine the knowledge, attitudes, and practices of face mask utilization, as well as associated factors, among Wachemo University (WCU) students in southern Ethiopia; additionally, the findings will be used as a guideline for those interested in researching related topics.

2. Methods and materials

2.1 Study setting, design, and period

An institution-based cross-sectional study design was conducted among Wachemo University’s main campus regular students from February to March 2021 who are recruited from the different departments. Wachemo University is of higher public education institution established in 2012 in Hossana town located in Southern Region at 232km south of Addis Ababa, which is the capital city of Ethiopia, and 194km far from the regional city Hawassa. WCU comprises of Durame campus and Nigist Eleni Mohamed Memorial Comprehensive Specialized Hospital (NEMMCSH) in addition to the Main Campus (MC). There are six colleges in WCU-Main-Campus and 10,371students enrolled in the regular program and from those 3,691 are female and 6,680 are male in the 2020/2021 academic year in the University [1416].

2.2 Sample size determination

The sample size was calculated using the single population proportion formula, considering the following assumptions and taking prevalence of 45.3% which is a study conducted in Police Health Facilities of Addis Ababa, Ethiopia [5].

n=(Zα/2)2p(1-p)d2 (1)

Where n = the desired sample size P = attitude of the healthcare provider towards proper face mask utilization = 45.3% (which is taken from attitude related study conducted at Addis Abebe police health facilities, Ethiopia,2020) Z1-α/2 = Critical value at 95% confidence level (1.96) d = the margin of error = 5% n = (1.96)2.0.453(1–0.453) / (0.05)2 = 381 and Using design effect (Deff = 2), because two stage sampling technique used, the final sample size required is: 2*381 = 762, for possible none response during the study the final sample size was increased by 5% to: n = 762 +5% of 762 which is: 38.1 By adding then, the total sample sizes was 800.

2.3 Sampling procedure

All regular undergraduate students registered for the 2020/2021 academic year in WCU main campus, were considered as the source population. A multistage sampling technique was used in the investigation. The first stage was created utilizing colleges, with three out of six colleges being chosen by lottery to increase representativeness. Seven departments at the selected colleges were proportionally allocated in the second step. The proportional sample size for each department was allocated in proportion to the number of students per department, and each respondent was chosen using a simple random sampling procedure. All regular undergraduate students registered from 1st to 6th year and attending their education during the study period in the main campus, WCU were included in the study. All weekend undergraduate students registered from 1st to 6th year and attending their education during the study period in the main campus were excluded from the study (Fig 1).

2.4 Measurement of variables

The purpose of this study was to determine WCU students’ knowledge, attitude, and practices regarding face mask utilization and associated factors in the COVID-19 pandemic. The primary dependent variable in this study was practice face mask utilization, but knowledge and attitude toward face mask utilization were also considered secondary dependent variables. The predictor variables were respondents’ basic socio-demographic characteristics such as gender, age, religion, family’s main source of income, marital status, students per dorm, current living situation, ethnicity, residency before joining the university, college, department, study years, cumulative grade point average (CGPA), monthly income, and sources of information about cloth face coverings.

In this study, knowledge about face masks and they are used were computed as follows: each correct response in the knowledge category was scored 1 and each incorrect response was scored 0. The final score was calculated and then labeled based on a score out of 9. The correct response of >7 out of 9 questions (>80%) was considered as good knowledge and ≤7 (≤80%) was considered as poor knowledge [5].

The attitude towards face mask utilization was measured by asking eight questions (e.g. willing to know the correct steps of wearing a face mask) to describe their level of agreement in a 5-point Likert Scale response options, scored from 1 to 5, strongly disagree, disagree, neutral, agree, and strongly agree. Subscale scores were obtained by summing item scores and dividing them by the total number of items. If it is above or equal to the average it was considered a positive attitude [5].

The practice of face mask utilization was analyzed as follows: each correct response in the practice category was scored 1, and each incorrect response was scored 0. The correct response of > 14 out of 18 questions (>80%) was considered as good practice and ≤ 14 (≤80%) was considered as poor practice [5].

2.5 Data collection and quality assurance procedures

The questionnaire was developed by reviewing different literature on the utilization of face masks and the guidelines of the center for health protection World Health Organization (WHO) and the Communicable Disease Control (CDC) [1719] and in consultation with experts from different fields to check the relevance and make necessary changes according to the study requirements. The questions were modified according to the suggestions received from the committee and output from the pre-test. Guidelines for layout, question design, formatting, and pretesting were followed. The questionnaire developed by the investigators contained the following 4 sections: 1 basic demographic characteristics (age, sex, religion, source of income, marital status, students per dorm, living situation, ethnicity, residence before joining university, college, department, study years, cumulative grade point average (cGPA), source of information and monthly income in birr), and 2 knowledge, 3 attitude, and 4 practices regarding face mask utilization. Three days of training were provided for data collected using a self-administered method by two trained data collectors and one supervisor. Data collectors pre-tested the questionnaire on 40 students from the Durame Campus of WCU branches two weeks before the primary study’s data collection began. The collected data were checked for completeness, accuracy, clarity, and consistency by the principal investigator. The questionnaire was prepared in English and then translated common language Amharic to check the consistency of the items and back to English to verify the accuracy in the common language Amharic. Face validation of the questionnaire was determined.

2.6 Data processing and analysis

The coded data were entered in Epi Data version 3.1 and exported for analysis to SPSS version 26. The key investigator was responsible for data entry. The descriptive analysis was performed and presented in frequency, using tables, graphs, and charts. In the bivariate analysis, variables having P-values less than 0.25 were entered into the multivariate analysis.

Bivariate analysis was performed to select variables for multivariate analysis. But, statistical significance was tested at the level of 5% at the multivariate level. Adjusted odds ratios (AOR) and 95% confidence interval using logistic regression were used to verify the existence and intensity of the correlation between independent and dependent variables. The fitness of the model was tested using the 0.796 Hosmer and Lemeshow test.

2.7 Ethical approval

The ethical approval was obtained from the ethical review committee (ERC) of the WCU College of Medicine and Health Sciences. Before beginning the investigation, permission was obtained from universities, colleges, and departments. Respondents were given written consent about the study, its goals, effects, and the significance of the data before they were enrolled. To ensure confidentiality, all information was rendered anonymous.

3. Results

3.1 Characteristics of respondents

Out of the 800 undergraduate students who were eligible to participate in the study, 36 were excluded (36 data were incomplete and were not considered for analysis), resulting in a 95.5% response rate.

This study identified majority of 599 (78.4%) and 660 (86.4%) of the college students were willing to know the correct steps of face mask-wearing and believe that face masks should be carefully put on and taken off, respectively. Regarding the effectiveness of face masks in preventing the spread of droplets, 668 (87.4%) of them believe it is effective while 91 (11.9%) of them disagreed. Half 639 (83.6%) of the professionals believe in changing face masks before going to another patient while 112 (14.65%) think it is not necessary to change face masks before going to another patient. Close to one-fourth of 335 (43.8%) disagreed it is not necessary to wear a face mask while in contact with patients and 320 (41.8%) said it is necessary to wear a face mask as am afraid of getting COVID-19. Almost 113 (14.79%) of the professionals believe that it is necessary to wear a face mask as being infected with COVID-19 is the worst thing that could happen to me (Table 3).

4. Discussion

The major purpose of this study was to assess the knowledge, attitudes, and practices of face mask utilization, as well as associated factors, among students at WCU in Southern Ethiopia during the COVID -19 pandemic. Masks are part of a larger package of preventative and control strategies that can help to restrict the spread of respiratory viral infections like COVID-19. Masks can be used for the protection of healthy people to protect themselves when in touch with an infected person or for source control to prevent onward transmission by an infected person or both [7].

According to the findings, the overall knowledge of the students was 223 (29.2%), their attitude was 673 (88.1%), and their practice was 684 (89.5%), When compared to a previous study conducted in a healthcare worker’s on proper face mask utilization and associated factors in police health facilities in Addis Ababa, Ethiopia [5], this was found to be 1.2 times lower for knowledge, two times higher for attitude, and 2.5 times higher for practice.

This study showed that students’ overall utilization of face masks was more than 1.5 times greater than a survey conducted in Malaysia [2, 5], which is similar to the reported from Hong Kong Chinese study [20] and the reported in a Saudi Arabian study [21]. A systematic review and meta-analysis undertaken to investigate the efficiency of face masks in preventing respiratory virus transmission revealed that proper mask use by healthcare and non-healthcare workers can lower the risk of respiratory virus infection by 80% [22]. The current study found that 89.5% of people in the study area used face masks, which is about 2.5 times higher than the research done in Ethiopian police health facilities [5]. This is almost 2.5 times higher than a study conducted at Dessie referral hospital in Northeast Ethiopia [23] and a study conducted in Pakistan [24].

The current study was in line with a study conducted in Hong Kong among community adults, in which the respondents indicated that they always wore face masks when caring for family members who had fevers or respiratory infections [25].

In terms of health professionals’ attitudes regarding face mask use, the current study found 2 times as many positive attitudes toward correct face mask use in police health facilities in Addis Ababa, Ethiopia [5]. These discrepancies could be explained by a qualitative study conducted among Vietnamese healthcare workers, which found that most discussants were hesitant to use face masks to protect against respiratory disease because they lacked adequate data on the effectiveness of face masks in the prevention of respiratory illnesses such as COVID-19 and other commentators also bring up the possibility that wearing a face mask could hurt the patient’s feelings [6].

According to the present study, 29.2% of students had a good understanding of how to use face masks. The result was 2.5 times lower than a study conducted in Ethiopia’s Addis Abebe police health facilities and 3 times lower than a study conducted in Dessie, Ethiopia [1, 23] and 2.5 times lower than in research done in Public Malaysia [2].

When compared to students in college medicine and health sciences, students in college natural and computational sciences were 76.8% less likely to be associated with poor practices in the use of face masks during the COVID -19 pandemic (AOR: 0.23; 95% CI: 0.13, 0.40). This could be because different colleges in higher education had varied grades, understandings, and subject areas.

Students with good knowledge were 4.4 times more likely than students with poor knowledge to have poor practices when using face masks (AOR = 4.40; 95 percent CI; 2.13, 9.14). This could be due to a lack of understanding, and those students with good knowledge would try to use the face mask properly. The diverse study demographics, sample size determination, and operational definition could all play a role in this disparity.

5. Conclusion

When compared to other research, WCU students had positive attitudes and good practices regarding the use of face masks, but they had little knowledge about the use of face masks. Face mask use was strongly linked to the college of natural and computational science and having a thorough understanding of face mask use. For those at risk of a COVID-19 pandemic, comprehensive awareness efforts and education initiatives on the use of about-face masks by authorities were required. During this epidemic, authorities should develop policies and guidelines that cover the many types of face masks, their use, and the importance of face mask utilization.

5.1 Limitation

There are some drawbacks to this study. One of the drawbacks is bias as a result of the study design (cross-sectional) because the data were collected at specific time points and cause and effect relationships could not be investigated. This research was also restricted to a quantitative method. Furthermore, a lack of comparable research hampered the ability to compare the findings of this study to those of other investigations.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The authors presented a very important topic that if properly addressed would help control the spread of COVID-19 pandemic. They intended to identify the KAP of college students as regards the use of face masks.

major changes are needed to make this manuscript suitable for publication:

Introduction section is very long, not properly constructed, no flow of ideas and lacks study rationale. Authors may start by describe the types , importance and uses of face masks mainly during the current pandemic, then present the current evidence in this both internationally and in their country, with a proper rationale statement/paragraph.

the sentences in lines 193, 195, 196 need to be corrected to avoid misunderstanding.

methods section: The results of the students tested in the pilot study were included in the study?

How did the authors use the dependent variable?

all questionnaire items need meticulous language revision and proof reading:

Many questionnaire items are not suitable for the subtitled domain, hence doesn't reflect the targeted domain, e.g.,

Among the Attitude items 27,28,29,30,31,32,34 don't fit as attitude testing items

For practice section : 58,59,60,61,63,64,65 test knowledge or attitude but not practice.

Items with repeated meaning in the questionnaire as

56, 57

63,64,65

many Items are difficult to be understood e.g., 19, 40

results section and discussion need to revised after correcting the methods

conclusion does not reflect the results: awareness campaigns, educational session are needed not training sessions (results of knowledge is poorer than practice and attitude , so training will not solve the problem

Reviewer #2: This is an interesting study of the how facemasks are viewed in the study population during the COVID-19 pandemic. However, there are a few concerns that warrant a revision of the manuscript prior to publication.

1. The introduction is overly long and contains contradictory information. For example, the WHO stance is mentioned to be both not recommending and recommending masks. The paragraph starting on line 55 seems out of place. A major edit of this section would greatly benefit readability and help emphasize the main point of the paper.

2. The methods regarding how the study population was selected is unclear. Specifically, if the university has approximately twice as many male students, why is the study population primarily female?

3. The survey questions themselves, and how they were scored, are unclear. Were they provided to the participants exactly as shown in the appendix? How were the questions developed?

4. The text of the results section repeats a lot of what is in the tables and figures, and there are typographical errors.

5. The comparison with other similar studies is a bit of an overreach, as the methods varied. However, the authors' conclusions of their own study was reasonable given the study methods.

Overall, this manuscript has the potential to share some interesting information, and may prove especially valuable to locations similar to the study location. However, the manuscript is not publication ready as-is and consultation with a skilled medical editor is suggested.

Reviewer #3: This study examines the knowledge, attitudes and practices surrounding the use of face masks. The topic explored is an important one, especially given its use as a public health measure across the world and the controversy associated with it. While this study attempts to answer an important question, I have a few issues regarding it.

-Abstract: Only one set of results are presented in the abstract. Was this the primary outcome?

-Introduction: Please provide references for the statements made in the introduction line 85, line 88, line 110.

-Line 115: what is the difference between pre-asymptomatic and asymptomatic?

Independent variables: lines 193-198, I assume these are the independent variables but they need to be phrased as such.

-Please provide the objectives and the primary/secondary outcomes of the study.

- What was the rationale behind collecting data on religion, marital status, living situation etc. Did the authors have a hypothesis on whether these variables would affect the outcome?

- Discussion: I'd like to see some explanation and discussion of the results, in addition to comparison with other studies. Give potential explanations as to why there were differences between the groups. e.g. why do the authors think that those who were married had higher rates of negative attitudes?

- Would there have been an element of social desirability bias when questioning students on their attitudes towards face masks?

- Please describe the limitations of the study

-Conclusion: The authors state that "comprehensive training about face mask utilization should be designed and given by authorities". This needs to be expanded in the discussion. How did this study show that training by authorities was required? The study population was quite niche (young students, high education background), these results may not be generalizable to the whole population, so conclusions need to be made with this caveat in mind.

- The manuscript would benefit from a review of the English language/grammar, with particular attention given to tense, punctuation and sentence structure.

Additional Editor Comments:

Thank you for your responses. The responses to the reviewers’ comments are in many cases unclear and I recommend that you review these original comments and ensure that they are addressed, or a detailed response as to why changes have not been made are provided. The items below are particularly of note:

1. Reviewer comments relating to the methods. Specifically,

a. How were the questions developed and validated including how they were assigned to domains? This information needs to be included in the manuscript.

b. How were the questions scored?

c. What was the rationale for the way in which the attitude questions were scored & why was being above the average considered a positive response particularly give this is nonparametric data (line 155-159). Please provide the statistical rationale for this analytic decision.

d. Was the questionnaire provided exactly as in the appendix?

e. If the student population is predominantly male yet the study population is mainly female then this suggests bias in the study recruitment process and limits generalisability of the results. This is not addressed in the manuscript

2. The English has improved but there remain sentences that are unclear, for example “The study showed that the overall knowledge, attitude, and practice of the students towards face 37 mask utilization were 223 (29.2%), 673 (88.1%), and 684 (89.5%) respectively” – it is unclear what is being reported here (i.e. 29.2% for knowledge actually mean). Further it is incorrect to say that a value is ‘about’ and then give the exact value (e.g. line 196 “About 291(38.1%) ..”). Please carefully edit the work for English grammar and spelling.

3. Line 57 “COVID-19 is a virus …” is not correct. The name of the virus is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

4. Please provide the objectives and the primary/secondary outcomes of the study

5. For the cumulative GPA to be meaningful to readers the scale for this measure needs to be given e.g. 1 to 7 with a pass at 4. Please use the same abbreviation for this throughout. What was the rationale for use of 3.25 as threshold for categorising students into two groups?
