Knowledge, attitude, practice towards breast self-examination and associated factors among women in Gondar town, Northwest Ethiopia, 2021: a community-based study

Abstract

Introduction

Breast cancer is the most common type of cancer among women, particularly in low and middle-income countries. Breast self-examination is one of the non-invasive methods of screening in which a woman looks at her breast for any abnormal findings like lumps, distortions, or swellings. Despite, realized effects of breast self-examination in detecting breast cancer earlier, the vast majority of the cases still present with an advanced stage.

Objective

This study aimed to assess knowledge, attitude, and practices toward breast self-examination and associated factors among women in Gondar Town, Northwest Ethiopia, 2021.

Methods

A community-based cross-sectional study was conducted on women living in Gondar town. A simple random sampling method was used to select 571 participants. Interviewer administered questionnaires were used for data collection. Data was entered into Epi-data version 4.6 and exported to Statistical Package for Social Science (SPSS) version 25 for analysis. Multivariate logistic regression was used where a p-value < 0.05 was used to identify variables significantly associated with the outcome variable.

Result

From the total of 571 women, about 541 participants were involved in the study with a response rate of 94.7%. Of these, 56%, 46% and 45.8% of women had adequate knowledge, favourable attitudes, and performed breast self-examination (BSE) respectively. Women College and above AOR: 3.8 (95% CI: 1.43–10.14) and spouses College and above AOR: 3.03 (95% CI: 1.04–8.84), Women College and above AOR: 4.18 (95% CI: 1.59–10.92) and history of breast cancer AOR: 6.06 (95% CI: 2.19–16.74) and knowledge level AOR: 2.67 (95% CI: 1.18–6.04) were significantly associated with knowledge, attitudes, and practices towards breast self-examination respectively.

Conclusion

The findings of this study were considerable for inadequate knowledge, unfavourable attitude and poor practice towards BSE among women. Emphasis should be made on boosting the knowledge, attitude, and practice of the women toward breast self-examination and strengthening the implementation of comprehensive, systematic, and continuous BSE educational programs that were recommended along with a breast cancer awareness campaign.

Introduction

Breast cancer is a type of malignant tumor that starts in the cells of the breast and commonly occurs in women [1]. This abnormal cell could destroy healthy tissue and then, spread beyond its usual boundaries [2]. Non-communicable diseases (NCD) including breast cancer considered not prevented, which is a noticeable common false perception of the community but it is a preventable cause of morbidity, disability, and mortality [3]. The most common risk factors of breast cancer are being a woman and getting ≥ 50 years old, having dense breasts, having a family history of breast cancer, early menstruation, and late menopause, late pregnancy, being on birth control pills, race, atypical hyperplasia of the breast, and previous treatment using radiation therapy [4, 5]. Lifestyle factors are obesity, lower amounts of physical activity, alcohol, and foods like high fats and low fiber diets [5]. Evidence suggested that; getting regular physical activity, staying at a healthy weight, limiting the amount of alcohol drink, avoiding the use of postmenopausal hormone therapy, breastfeeding, eating more fruits, vegetables, and fewer animal fats is linked with many health benefits and lower the risk of breast cancer [5]. Besides, it not only affect the breast tissue, but also spread to other part of the body organs like liver and lungs [6, 7].

According to global cancer statistics; breast cancer accounts for about 25% and 15% of total incidence and death respectively [8, 9]. In American an average risk of a woman of developing a breast cancer was 13% which is equivalent to one in every eight women had a chance of developing in their life time [10]. It is an important public health issues, not only in the developed world but also in resource limited nations [11]. It is the most frequent cause of death among women and estimated that 70% of all breast cancer cases worldwide were reported in low and middle-resource countries [12]. The incidence of breast cancer accounts for 22.6% of all cases of cancer in Ethiopia [13]. Breast self-examination (BSE) is one of the non-invasive methods of screening in which a woman looks at her breast for any abnormal findings like lumps, distortions, discharges or swellings with an intention to detect it early for early initiation of treatment and better chance of survival for breast cancer patients [14, 15].

Knowledge, attitude and practice of BSE have been reported in different countries. In regards to BSE knowledge 22.7% in Vietnam [16], 63.8% in Turkey [17], 41.5% in Libya [18], 34% in Sudan [19], 78% in Cameroon [20], 25.6% in Addis Ababa [21], 34.2% in Arba Minch [22], 43.1% in Jima [23], and 55.5% in Adwa town [24] had an adequate knowledge about breast self-examination. As per women’s attitude 64.01% in Saudi Arabia [25], 87.2% in Pakistan [26], 74.9% in Libya [18], 53.4% in Addis Ababa [21], and 46.3% in Adwa town [24] had a favorable attitude towards BSE. Considering practice towards BSE 43% in Saudi Arabia [27], 24.9% in Pakistan[26], 21% in Oman [28], 15.8% in Vietnam [16], 8.5% in turkey [17], 37.6% in Ghana [29], 38.5% in Cameroon [30], 39.2% in Egypt [31], 12.1% in Libya [18], 20.6% in Sudan [19], 13.3% in Arba Minch [32], and 18.6% in Addis Ababa [33] had a good practice of breast self-examination.

Factors affecting knowledge of the BSE were reported from the different countries. These are age, marital status, level of education, information of BSE, medical background, access to internet, source of information, and level of income. However, only the education levels and medical background for attitude towards BSE [16, 18, 26, 31, 33, 34]. Practice factors are almost similar to that of knowledge other than health education on breast cancer, knowing BSE techniques, occupation, and family history of breast cancer were related to women’s knowledge, attitude and practice towards BSE [16, 18, 33–38].

BSE is the only feasible approach that is cheap and easily applied method across wide population. Its ultimate purpose is early detection and treatment. Despite, its importance as an early detection strategy, poor knowledge of women has been a major obstacle. So, amplifying women’s knowledge, attitude, and practice towards BSE through creating breast cancer awareness campaign [39–43].

In our study area, there is a lack of evidence on women’s knowledge, attitude, and practice towards breast self-examination (BSE). Therefore, this study was aimed at assessing women’s knowledge, attitude, and practice on breast self-examination and thereby generates appropriate information that can be used by the central Gondar zonal health office and non-governmental organizations in the prevention and interventions of breast cancer.

Methods and materials

Study design, and period

A community-based cross-sectional study was conducted from April to May 2021.

Study setting

The study was conducted at Gondar Town, Northwest Ethiopia. Gondar Town is located 748 km from Addis Ababa the capital city of Ethiopia and 180 km from Bahir Dar capital city of Amhara regional state. The town has 6 sub-cities with 25 Kebele and 127,115 houses. Gondar Town is one of the ancient and densely populated towns in Ethiopia. According to the central Gondar zonal health office 2021 GC report, Gondar has a total population of 432,191 of whom 215,663 are men and 216,538 women. Nowadays the town is growing and it had 8 health centers, more than 15 private medical clinics, one private primary hospital, and one Comprehensive Specialized Hospital serving about 5 million populations.

Source population and study population

All adult women who are living in Gondar town were the source population. All women who are living in Gondar town during the data collection period were considered as the study population.

Inclusion and exclusion criteria

All women who were 20–70 age group living in Gondar town during the study period were included. Women who are severely ill during data collection time and those who refuse to participate in the study were excluded.

Sample size determination and calculation

The actual sample size for the study was determined using single population proportion formula with the assumption of 34.2% knowledgeable of BSE [32], 95% confidence interval; (α = 0.05), 5% margin of error, 10% none response rate, and 1.5 design effect.

$$\text{n}=\frac{\left(\text{Z}\mathrm{\alpha }/2\right)2\text{p}\left(1-\text{p}\right)}{\text{d}2}=\frac{\left(1.96\right)2\left(0.342\right)\left(0.658\right)}{\left(0.05\right)2}=346,$$

where n = is the minimum sample required; P = population proportion, 0.342; d = the margin of error, 0.05; Z = the upper percentile of the normal distribution at 95% CI.

By Multiply 1.5 design effect n = 519, adding 10% non-response rate = 52 and the final sample size would be 571 (Table 1). Sample size calculation on second the objective in the same study showed that only practice was significantly associated with BSE (Table 2).

The final sample size was from a single population proportion and the second objective was used the maximal one take from single population proportion knowledge of BSE = 571.

Sampling technique and procedures

A multi-stage sampling method was applied for the selection of houses from each Kebele. Firstly, Out of 25 kebeles in the Gondar town, 7 kebeles such as Aribengochi, Adebabayeyesuse, Abajalie, kehaeyesus, Shiwaber, Hidasie, and Aba Samuel kebele were randomly selected by lottery method to represent all kebeles (28% representativeness). Secondly, a systematic sampling technique was used to label the households within each Kebele The proportional allocation formula for each Kebele is $n=\frac{\mathit{njXnf}}{N}$; Were, nf = final sample size, nj = total number of houses each Kebele, N = total number of houses (Fig. 1). Lastly, a simple random sampling was used to select 571 study participants within households using the sampling frame.

Data collection tools and procedures

The questionnaire was adapted from different works of literature [26, 44, 45]. The questionnaire was first prepared in English, and then it was translated into Amharic language and back to English. It contains four parts such as socio-demographic characteristics (n = 9), knowledge (n = 12), attitude (n = 13), and practice (n = 8) items. Then the data were collected by 5 data collectors using face-to-face interviewer administer questionnaires. The overall supervision was carried out by the principal investigator.

Operational definition

Adequate knowledge: It refers to participants who scored mean and above values 8 from the provided 12 close-ended questions about the knowledge of BSE [46].

Inadequate knowledge: It refers to participants who scored below mean values 8 from the provided 12 close-ended questions about the knowledge of BSE [46].

Favorable attitude: It refers to participants who scored mean and above values 6 for attitude-related questions towards BSE, which was measured by the provided 12 questions [46].

Unfavorable attitude: It refers to participants who scored below mean values 6 for attitude-related questions towards BSE, which was measured by the provided 12 questions [46].

Good practice: It refers to those who checked or perform BSE at least once per month just a week after each menses [47].

Poor practice: It refers to those who practice BSE other than the correct time in the cycle [47].

Data quality control

Pretest was done on 5% of the total sample size from the non-selected kebele of the same population before 4 days of actual data collected. Two days of training were given for data collectors and supervisors by investigators on the objectives of the study, ethical considerations, the content of the questionnaire, and how to conduct the interview. Based on the pre-test, questionnaires were edited, and necessary corrections made were on order of questions and that poses participant to confusion. The reliability of the tool on Cronbach’s alpha results knowledge = 0.81, attitude = 0.86, and practice = 0.71. The collected data was checked out for completeness, accuracy, and clarity by the principal Investigators before data entry.

Data processing and analysis

Data were entered using Epi data version 4.6 software and analyzed using SPSS version 25. Data cleaning and cross-checking were done before analysis. Descriptive statistics were summarized using the mean, and standard deviation. Frequencies and percentages were used in the presented table, figures and text. Multivariate logistic regression analysis were used to identify factors where p-value < 0.05 was declared as significantly associated with knowledge, attitudes, and practices of breast self-examination.

Factors associated with breast self-examination

All independent variables entered into the logistic regression (multivariable logistic regression analysis). Women’s and husbands' education level were significantly associated with knowledge. The age of the women and women’s educational level was significantly associated with the attitude of BSE. History of breast cancer and good knowledge of BSE were significantly associated with performing BSE. Women college and above were about 4 times [AOR: 3.8, (95% CI: 1.43–10.14)] more likely to know of BSE than those who uneducated women. The spouses whose educational level College and above was about 3 times [AOR: 3.03, (95% CI: 1.04–8.84)] more likely to be knowledgeable towards BSE than those who had an illiterate husband (Table 7).

Women who have personal and family history of breast cancer were about 6 times [AOR: 6.06, (95% CI: 2.19–16.74)] more likely to perform BSE than women who do have not the history of breast cancer. A woman who has adequate knowledge of BSE about 3 times [AOR: 2.67 (95% CI: 1.18–6.04)] is more likely to perform BSE than women who have inadequate knowledge (Table 9).

Discussion

The aim of this study was to assess knowledge, attitude, practice, and associated factors of breast self-examination among women in Gondar town. In this study, more than half 56% (n = 200) (95% CI: 52–62%) of the study participants had adequate knowledge regarding BSE, which is comparable with study conducted in Ethiopia that indicated 55.5% in Adwa town [24]. This similarities could be due to similar study subjects.

However, the finding is higher than that of Vietnam 22.7% [16], 34% Sudan [19], 41.5% Libya [18], 34.2% Arba Minch [32], 43.1% Jimma [23], and 25.6% Addis Ababa [21]. The difference might be due to by self-reporting data collection technique in Vietnam and Sudan, and the clustered sampling procedure was used in Libya. The self-reporting data collection method requires participants to respond to the researcher's questions without his/her interference [48]. In Ethiopia, the possible justification might be the educational level difference. In our study, 29.8% of participants were College and above educational status, but only 14.4% of study participants in Arba Minch, and 18.8% in Jima were college and above educational status. This finding is lower than the study conducted in Cameroon 78% [20], and 63.8% in Turkey [17]. The possible justification might be due to socio-economic, and study population differences. The current study was community-based, but that of Cameroon was conducted on patients attending a surgical outpatient clinic.

In this finding, about 46% (95% CI: 42–52%) of participants had a positive attitude towards breast self-examination, which is comparable with the study conducted in Ethiopia that indicated 46.3% in Adwa town [24].This consistency might be due to similar socio-cultural status and study population whose age were 20–70. However, it is lower than the studies conducted in Saudi Arabia 64.01% [25], 87.2% Pakistan [26], and 74.9% Libya [18]. This difference might be due to sampling size difference, educational level, and participant’s knowledge towards BSE, occupational difference, and information access availability.

In this finding, Nearly one-third 31% (n = 77) (95% CI: 25–37%) of participants had good practices towards BSE, which is comparable with the study done in Addis Ababa, 28.4% [33]. This consistency might be due to similar socio-cultural and economic status. Besides, factors that affect practice for early detection of BSE might be similar in both study settings. On contrary, this study is higher than the studies conducted in Arba Minch 13.3% [32], 12.1% Libya [18], and 8.5% Turkey [17]. The difference might be knowledge difference, and in Arba Minch, the majority (45%) of the participants are illiterate. On the other hand, this finding was lower than the studies conducted in Saudi Arabia 43% [27], and 37.6% in Ghana [29]. The possible justification might be educational and knowledge differences. In Saudi Arabia, the majority (65%) of participants had adequate knowledge about BSE, and 79% of the participant had an educational level completed university, whereas 88% of participants were aware of BSE in Ghana.

In this study, women’s educational level at College and University were about 4 times [AOR: 3.8, 95% CI: (1.43–10.14)] more likely to be knowledgeable with BSE than those who are illiterate. Also, the women whose husbands had an educational level College and University were about 3 times [AOR: 3.03, 95% CI: (1.04–8.84)] more likely to knowledgeable than those had illiterate husbands. Evidence shows that training women about breast self-examination goes correspondingly with their educational attainment of College level and above has a positive impact on their related knowledge and practices [49, 50].

Women’s College and above was also one of the significant factors for the attitudes of breast self-examination, women’s College and above was about 4 times AOR:4.18, (95% CI: 1.59–10.92) and secondary school was about 3 times [AOR: 2.80, 95% CI: (1.25–6.29)] more likely to had positive attitude towards BSE than women those who are illiterate. it was supported by the study done in Libya [18], and Turkey [17]. This might be due to educational attainment of secondary school and above could increase women’s attitudes towards breast self-examination besides it also enhance compliance towards breast self-examination behavior [51].

In this study, women who have a history of breast cancer were about 6 times [AOR: 6.06, 95% CI: (2.19–16.74)] more likely to perform BSE than their counter parts. This study was in line with the studies conducted in Jimma [23], Addis Ababa [36], and Libya [18]. A family history of breast cancer is positively affecting the practice of breast self-examination [52]. This could be women with a history of breast cancer performing breast self-examination at a regular basis and making them more cognizant, which in turn may lead to an earlier diagnosis of breast cancer.

Limitations

As practice was not directly observed rather we used checklist that will not know how exactly they were practicing it. Other limitations were being conducted in a single urban community, which may not be representative of the rural community or other urban communities in Ethiopia.

Conclusion

The findings of this study were considerable for inadequate knowledge, unfavorable attitude and poor practice towards BSE among women. Emphasis should be made to boost the attitude and practice of the women towards breast self-examination and strengthening of the implementation of comprehensive, systematic, and continuous BSE educational programs were recommended along with a breast cancer awareness campaign.
