Factors influencing COVID-19 preventive behavior in Thanlyin township, Yangon region, Myanmar

INTRODUCTION

COVID-19 according to World Health Organization (WHO), it is a novel lung condition caused by an emerging virus. This virus was originally found in Wuhan, China, in December of 2019. The World Health Organization declared COVID-19 an international public emergency on 30 January 2020, and a pandemic on 11 March 2020. This virus is part of the cluster of severe acute respiratory syndrome (SARS)-like viruses.¹ COVID-19 patients reported symptoms ranging from mild to severe. Symptoms may appear 2-14 days following exposure to the virus. Its symptoms include fever or chills, cough, shortness of breath or difficulty breathing, exhaustion, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea.² The disease is highly contagious and spreads mostly through droplet transmission, which occurs when a person comes into close contact (within 1 m) with someone who has respiratory symptoms (e.g., coughing or sneezing), exposing them to potentially infected respiratory droplets. Fomites in the ill person's immediate environment can also be a source of transmission.³ Behavior by humans has a vital role in disease transmission.

There is a substantial link between different socioeconomic variables and preventive behaviors. Age, lifestyle, health, mental state, and knowledge all have an impact on a person's ability to avoid or control infections through self-care.⁴ Individuals with one or more chronic conditions and knowing someone who has died from COVID-19 were more likely to practice all three preventive behaviors and also knowing someone affected by COVID-19 (has it/died) influences uptake of preventive behaviors due to higher risk perceptions.^4-10 Compared with participants who did not have positive cases in their social circles, those who had immediate family members or close friends and relatives who tested positive were more likely to prevent behavior for COVID-19. Participants' sex, age, ethnicity, marital status, and employment status were also associated with preventive behaviors.¹⁰ Preventive techniques such as handwashing with soap and water, wearing a face mask, social distancing, covering the mouth and nose when coughing, and avoiding touching the face can help minimize COVID-19 transmission.¹¹ COVID-19 related health information received online and family members, close friends or relatives, or people in local communities tested positive for COVID-19 was positively associated with engagement in all types of preventive behaviors.¹⁰

Therefore, this research intended at assessing factors influencing COVID-19 preventive behavior among selected households. Aim of study were to determine the association between socio-demographics, knowledge and preventive COVID-19 behaviors in the Thanlyin township residence over the age of 18 years old. Yangon region, Myanmar.

METHODS

This cross-sectional descriptive study was conducted from July 2022 to December 2023 that collected quantitative data using an interviewer-administered questionnaire that was converted to Open Data Kit (ODK), a mobile data tool in Thanlyin township, Yangon, Myanmar.

Inclusion criteria

The study's inclusion criteria were being at least 18 years old and living in Thanlyin township, Yangon, Myanmar.

Exclusion criteria

Exclusion criteria were unwillingness to continue participating while responding. The number of sample size was calculated with significant level of 5% and 95% confidence level. In which data used from the study conducted by the previous literature.⁵ The required sample size at 700 people. Multi-stage sampling was used.

Statistical analysis

Data analyses were performed using STATA (version 15.1). Data were presented as mean±standard deviation for continuous data and proportions and percentages for categorical or qualitative data. To determine the association between socio-demographics, knowledge and preventive COVID-19 behaviors, one-way analysis of variance (ANOVA) and independent t-test were used. Multiple linear regression was used to analyze the factors influencing preventive COVID-19 behaviors.

Socio-demographic variables were significantly associated with behavior score in univariate analyses (p<0.05) and were adjusted in the regression analysis. Multicollinearity of independent variables was detected if the variance inflation factor (VIF) was more than 10. A p value <0.05 was set as statistically significant.

Measures

The survey included questions on basic socio-demographics, knowledge, and preventive behaviors related to COVID-19.

Socio-demographic factors

Socio-demographic characteristics questionnaire included 10 items, such as residence, gender, age group, marital status, education, occupation, smoking habit. The participants were also asked about their history of chronic illness; history of infection due to COVID-19 in themselves or the people around including family members and their underlying diseases.

Knowledge about COVID-19

Knowledge was assessed based on five domains (i.e., symptoms, the spread of infection, source of information, vulnerable group and prevention), each consisting of true or false statements.

COVID-19 preventive behaviors

Questionnaire to preventive behavior scale consisted of a list of 33 behaviors in three sections including Individual preventive behavior practices, preventive behavior practices when entering the house, preventive behavior practices when leaving the house. The participants’ adherence to each behavior was scored on a 3-point Likert scale of 0=never, 1=sometimes and 2=always.

The final score was the sum of the scores of each section; therefore, the minimum and the maximum scores were 0 and 66, respectively.

RESULTS

Out of 700 respondents, male and female were equal distribution and 25% resided in urban areas and 75% in rural area that is 1:3 ratios in this study with an average age of 42.92 years (SD=12.704, range 18–89 years). Most of the participants were between 41 to 60 years of age (48.1%), 82.4% were married, 22.1% were high educational level, 48.4% were dependent, 72.9% were never smoker (Table 1).

Regarding history of chronic diseases and COVID-19, 51.3% had underlying diseases, only 16.7% had past history of COVID-19 and 70.1% had underlying diseases among COVID-19 patients (Table 1).

Knowledge about COVID-19

The overall mean score of knowledge related to COVID-19 was 25.95±7.07. The COVID-19 knowledge mean score was significantly highest among the participants who live in urban area (26.77±6.993, t=1.189), family members who had COVID-19 history (28.43±6.27, t=4.19), and COVID-19 patients who had underlying diseases (29.00±5.18, t=3.007) and they were statistically significant at p value of p=0.016, p=0.000 and p=0.003 respectively.

Table 5 showed that linear regression analysis of the socio demographic as associated with COVID-19 preventive behaviors. According to the gender distribution, these findings indicated that being male is associated with more preventive COVID-19 behaviors compared to females, however, it is not statistically significant (β=2.231, p=0.05). Regarding the age distribution, these results indicated that 41 to 60 years more preventive COVID-19 behaviors compared to other age group, however, it is not statistically significant (β=2.316, p=0.077). Regarding the marital status distribution, these results indicated that single more preventive COVID-19 behaviors compared to other marital status group, however, it is most statistically significant (β=5.114, p=0.006). Regarding the residence distribution, these results showed that residing in an urban area is associated with more preventive COVID-19 behaviors compared to rural areas which is statistically significant (β=2.665, p=0.042). Regarding the smoking status distribution, this finding showed that people who had current smoking habit had higher preventive COVID-19 behaviors compared to who had never smoke and ex smoke which is not statistically significant (β=0.218, p=0.879). Regarding the educational status, this finding suggested that individuals who passed high school education practices most in preventive COVID-19 behaviors compared to the other educational status which is statistically significant (β=8.663, p=0.000). Regarding the occupational status, this finding suggested that individuals who worked outside practices most in preventive COVID-19 behaviors compared to the other occupational status which is statistically significant (β=1.760, p=0.129). By the comorbidities of the study participants, these results showed that having comorbidities is associated with less preventive COVID-19 behaviors which is statistically significant (β=-2.504, p=0.028). Regarding the family history of COVID-19 among study participants, these results suggested that individuals with a family history of COVID-19 have more preventive COVID-19 behaviors compared to those without such a history which is strongly statistically significant (β=6.913, p=0.000). According the underlying diseases of study participants, these findings indicated that individuals with underlying diseases have more preventive COVID-19 behaviors compared to those without underlying diseases, however, which is statistically significant (β=7.489, p=0.001).

DISCUSSION

In this study, it revealed that disparities between genders in health-related knowledge and practices, frequently linking greater health participation to women which is similar with previous research.^12,13

These results were similar with earlier studies that show younger people typically participate in more preventive practices and have greater levels of health knowledge, for instance, discovered that younger persons had a higher propensity to look for and interact with health information online, which may account for their better knowledge ratings.¹⁴ On the other hand, the older persons may have difficulty obtaining information or may perceive danger differently, which could explain why they score lower on preventative actions and knowledge.¹⁵ It is imperative to comprehend how age affects COVID-19 knowledge and preventative behaviors in order to customize public health interventions. The found substantial differences imply that alternative strategies may be needed for younger and older age groups. For instance, community-based programs or digital literacy initiatives could be used to reach older persons with interventions that emphasize the value of preventive practices and better information access.

Using social media and other online platforms to maintain engagement and reinforce correct knowledge could be beneficial for younger adults.

These results were same with earlier research suggesting that marital status can affect people's health-related beliefs and practices. For example, single people tend to know more about health because they have access to a wider range of information sources than married people, who may depend more on their close friends and family but not difference with previous research.^11,16

People who live in urban frequently have better access to medical facilities and health information, which can result in more effective preventative measures which is similar with the previous study.¹⁷ The necessity for focused public health initiatives is highlighted by the notable differences in preventative practices between urban and rural populations. While rural areas might need more concentrated efforts to increase participation with these habits, urban areas might benefit from strengthening current preventive measures. In order to encourage and facilitate preventive measures, this could entail using mobile health units, community engagement initiatives, and local leaders.

People who with higher education levels were more likely to follow COVID-19 preventive measures, similar with the previous research.^13,14 In this study, findings that those working outside have higher knowledge scores align with other studies. However, the lack of significant differences in preventive behaviors contrasts with some research suggesting that occupational settings can influence health behaviors.¹⁸

These results not similar with some studies that indicate individuals with comorbidities may be more cautious and adhere more strictly to preventive behaviors.¹⁹ The significant difference in preventive behaviors emphasizes the importance of targeted interventions for individuals with comorbidities. Public health strategies should highlight personalized guidance and support for this group to enhance their adherence to preventive measures. This could involve tailored educational materials, remote health monitoring, and accessible healthcare services to mitigate the risk of COVID-19 complications. These results align with existing literature suggesting that personal experiences or proximity to COVID-19 cases can enhance knowledge and prompt behavior change. Studies have shown that individuals with direct exposure to COVID-19 cases are more likely to adhere to preventive measures and seek out accurate information to protect themselves and their families.⁵

These results are consistent with existing literature suggesting that personal or family experiences with severe illness can lead to heightened health awareness and behavior change. Studies have shown that individuals with underlying health conditions are more likely to engage in protective behaviors during pandemics to reduce their risk of infection and severe outcomes.⁵ The significant differences observed in both knowledge and preventive behaviors underscore the profound impact of personal or familial health experiences on health-related attitudes and actions. The significant differences in knowledge and behaviors highlight the importance of personal or familial health experiences in shaping health outcomes during a pandemic. Public health strategies should incorporate these experiences by utilizing personal narratives and real-life examples in educational campaigns. Emphasizing the severity of COVID-19 and the importance of preventive measures through direct accounts can resonate more deeply with individuals and communities affected by underlying health conditions.

Limitations

In this study, one of the main limitations was the sampling method, which could affect the generalizability of the results, as the findings may not be representative of the larger population. Future research could address these limitations by securing representative a sample by utilizing more objective data collection methods.

CONCLUSION

In summary, this research showed that there were no gender-based disparities in our sample's participation with preventative behaviors or understanding of COVID-19. There are notable age-related variations in COVID-19 knowledge and preventative behavior involvement. Older people (above 61) had the lowest knowledge levels, whereas younger people (18–40 years old) showed the highest. These results indicate the necessity of developing age-appropriate public health initiatives in order to successfully spread knowledge and promote preventative practices among all age groups. When compared to rural populations, urban residents showed a stronger commitment to preventive activities. And also point toward the necessity of customized public health initiatives that tackle the particular difficulties faced by rural communities and guarantee fair access to resources and knowledge in order to encourage successful preventative actions. Public health activities can be more successfully focused to reduce the spread of COVID-19 across various populations by being aware of and addressing these discrepancies. Regarding to the educational status, there are notable variations in COVID-19 knowledge and preventative practices. Greater understanding and compliance with preventive actions are linked to higher educational attainment. These results underline the necessity of focused public health initiatives to raise health literacy among individuals with lower educational attainment. In the context of COVID-19 and upcoming public health concerns, public health initiatives can be more successfully focused on improving knowledge and encouraging preventive behaviors across all educational categories by addressing these discrepancies. This will ultimately lead to better health outcomes. In this study, there was a significant difference in preventive behaviors but not in knowledge about COVID-19 among individuals with and without a history of comorbidity. While both groups may have similar levels of knowledge, individuals with comorbidities exhibit lower adherence to preventive behaviors. Public health interventions are essential to address the specific needs and challenges of individuals with underlying health conditions, ensuring comprehensive protection against COVID-19 and promoting overall health and well-being in vulnerable populations. This study showed that a past history of COVID-19 among family members significantly impacts both knowledge about COVID-19 and engagement in preventive behaviors. Individuals with direct family exposure to COVID-19 exhibit higher levels of knowledge and more proactive preventive behaviors. These findings underscore the importance of personal experiences in shaping health outcomes and suggest that public health interventions should harness these experiences to effectively communicate and promote preventive measures in communities. In addition, also showed that a history of underlying diseases in COVID-19 patients significantly impacts both knowledge about COVID-19 and engagement in preventive behaviors. Individuals with direct or familial exposure to severe cases of COVID-19 exhibit higher levels of knowledge and more proactive preventive behaviors. These findings highlight the importance of personal or familial health experiences in shaping health outcomes and suggest that public health interventions should harness these experiences to effectively communicate and promote preventive measures in communities. By understanding and addressing these dynamics, public health efforts can be more targeted and impactful in mitigating the spread of COVID-19 and similar infectious diseases in the future.
