Awareness and Knowledge of Colorectal Cancer in Qassim Region, Saudi Arabia

Colorectal cancer (CRC) is common cancer, and it ranks the third most commonly diagnosed cancer in the world [1]. CRC is also the fourth leading cause of death worldwide [2]. In Saudi Arabia, CRC is the second most common cancer, being the first among men (10.6%) and third among women (8.9%). According to the World Health Organization (WHO) in 2004, the death rate from CRC in Saudi Arabia is 8.3%. Moreover, the Saudi Cancer Registry reported an increase in CRC incidence between Abstract

Introduction cancer) and 63 for both men and women (for rectal cancer), whereas in Saudi Arabia is 60 for men and 57 for women [4].
Furthermore, Saudi patients are more likely to present at a late stage in comparison with western countries [1]. Screening for CRC can improve early diagnosis [3]. Early screening can prevent CRC by early recognition of precancerous polyps. Screening procedures include direct visualization of lesions through a flexible sigmoidoscopy and colonoscopy; a faecal occult blood test also is used. A significant proportion of CRC cases and deaths could be avoidable due to the slow transition from adenoma to adenocarcinoma [5]. Unfortunately, participation in CRC screening worldwide is relatively low despite the significant role of CRC screening in reducing incidence and mortality rates [2]. Barriers of participation in screening programs can be grouped in patient-level factors, including socio-demographics, psychosocial factors, healthcare system, and provider factors [4].
Accordingly, interventions must focus on these factors [2,3]. Knowledge of symptoms and risk factors encourages patients to participate in screening programs and present at an early stage [6]. The symptoms of CRC include a change in bowel habits, rectal bleeding, abdominal pain, and sudden weight loss. Age, family history of CRC, a low fiber diet, red and processed meat consumption, sedentary lifestyle, obesity, smoking, and excessive alcoholism are the risk factors of CRC [4]. Thus, evaluating the CRC knowledge in the Qassim population and assessing the awareness of CRC incidence, risk factors, symptoms, screening, and treatment according to various demographics was the aim of this research. This data will help determine specific areas in need of targeted education programs, with the overall goal of increasing participation

Materials and Methods
A quantitative observational, cross-sectional study Was employed using a self-administered electronic questionnaire in the Arabic language ( The participants selected by the convenience with the inclusion criteria of all males and females in Al-Qassim between March-June 2020 and Arabic speaker, 18 years and older. We excluded medical students, unfinished surveys, and lack of essential ability to read or write. The questionnaire consisted of 13 multiple choice questions and two short answer questions. The components of the inquiry were socio-demographic information, questions on knowledge related to the large bowel. Awareness about early signs/symptoms and risk factors of Colorectal cancer and Methods Used for Screening. The study's purpose was briefed, and the participants were instructed to select multiple answers wherever appropriate. Ethical approval was obtained from the Ethics and Research Committee of Qassim University. Data will be entered and analysed using Statistical Package for the Social Sciences (SPSS) software version 26. (IBM; Armonk, New York).

Results
One thousand four hundred thirty participants were enrolled in the study. Out of the total of 1116 (78%) were females, and 314 (22%) were males. The majority were between 18 -32 (49.7%) old. While 31.7 % were from 33-47, and 17.8% were from 48-62 years old.
The socio-demographic and characteristics of the participants, as shown in Table 1.
The majority of the participants, 829 (58.0%), were married, 18-32 years old (49.7%) university students (75.4%), and were female (78.0%).We further investigated and reported the highest percentage (33.1%) when CRC screening should occur at the age of 50. About 27.6% of participants reported that the most common symptoms of CRC are the presence of blood in the stool. Furthermore, we investigated and found most respondents (16.1%) did not know that smoking is a risk factor for CRC.
In addition, Table 1 reveals significant differences in demographic responses (level of education, age, marital status, and gender).

Level of education
Considering knowledge of participants about colorectal cancer, we performed analysis for seven questions related to the definition of the colon and related symptoms, mean knowledge was calculated. We found that the mean

Gender
In general, when it comes to CRC, gender does not significantly affect the level of knowledge (p-value 0.801), where mean scores of males and females were (3.6 for both). However, there a significant difference (p-value 0.041) concerning risk factors; we found that females have more knowledge about the risk factors than males (Table 4).

Marital status
Substantially, the married or previously married population had more Knowledge concerning CRC than those who had not already married (singles) where the score of knowledge was 3.5573 ± 1.2664 (Table 2).
In Table 3, we showed the percentage of each demographic item that answers each question in correctly.
There was a significant difference concerning knowing what the colon is according to the level of education. Postgraduate selected the correct answer (over 75.9%). However, the intermediate education selected it least frequently (538.9%; p-value 0.010).
Majority of participants knew the definition of the rectum (84.7%), Based on the level of education, likewise, there was a significant difference (P = 0.043); 84.7% of undergraduates responded correctly, although only 67.3% of people with secondary education answered correctly. However, only 67.3% of people with secondary education reacted correctly. Concerning screening for colon cancer, the majority of respondents 38.9% of postgraduates and university students agreed to screen starts at the age of 50. On the contrary, those among secondary education  (Table 3). For instance, formerly married participants (82.4%) correctly answered that the colon as part of the large intestine; compared to single individuals only responded correctly, 57.5% of the time (P ≤0.001). In contrast, regarding screening tools for CRC, single respondents answered correctly, 57.3% opposed to married participants (Table 5).

Age group
According to age, there were many significant The colon is?   "Yellow discoloration of the eyes and skin" was the most commonly recognized symptom by participants aged 18-32 years (63.9%), compared to the older population who thought CRC has no signs (p-value 0.003) ( Table 6).

Discussion
As already reported, and to our Knowledge, Currently, data on the perception of colorectal cancer in the Qassim population have not been identified. Therefore, in this study, we aimed to evaluate the level of knowledge and awareness among public in Qassim Region regarding colorectal cancer incidence of the disease, risk factors, symptoms, screening, and treatment options, and to correlate these findings with age, gender, marital status, and educational level.
The mean score of knowledge of the sample about colorectal cancer was 3.5573 ± 1.2664. This score means that most of the participants had answered almost 50 % of the questions correctly. Consequently, the general level of knowledge was moderate among the public in the Qassim region. Generally, gender does not affect while age, social status, and educational level significantly correlate with the degree of knowledge as older age, married with high education, had more understanding than others. Overall, most participants had a reasonable understanding of what colon and rectum are, however, when it came to proper colon function, how prevalent colon cancer is, and when colon cancer should be screened, there were wide gaps in knowledge.
Ahmad M. Zubaidi in his study found that most of the participants in his study had good knowledge about the location of colon and rectum however they had lower knowledge when considering the function of colon however he found that females, older respondents, and more educated respondents had (statistically significant) more Knowledge of CRC. He found that married individuals were more knowledgeable than single individuals [1]. This is in contrast to our study in the conception that females had more knowledge; in our research, we did not observe a significant correlation. The higher understanding of the married population was approved in other studies as Mohammed Alnuwaysir [7].
Most participants had a good knowledge considering the symptoms of colon cancer, especially, the presence of blood in stool and abdominal pain (Figure 3). These results also found in the study of Raed Saeed Saeed, which conducted in Kuwait, where he discovered that blood stool and lower abdominal pain were the most symptoms indicated by participants [8]. Besides, Mona Abdullah Alsayed found that 21.6% of participants in her study were aware of the symptoms associated with colon cancer, where blood in the stool, weight loss, and abdominal pain were the most identified symptoms [9], and this is resembling our study. Moreover, our research   [10,11]. However, many studies found that female and higher education increased the level of knowledge we did not find any association between these factors and knowledge about colon cancer symptoms. Considering risk factors, 26.7% of the sample defines inflammatory bowel disease correctly as a risk factor for CRC, while 20.9% for family history, 18.4% for polyps, 17.8% for fat-rich food, and 16.1 % for smoking Figure 4 ( risk factors). Raed Saeed Saeed found that among many risk factors provided to his participants, the main risk factors identified by them were genetic and family history [8]. Moreover, Ahmad M. Zubaidi, found that the main risk factors for developing CRC determined by the participants in his study include a family history of CRC, inflammatory bowel disease. Also, he found that older participants thought that the family history of CRC is a risk factor for CRC more than other demographics [1], and this in contrast to our results where there is no significant association between age and knowledge about risk factors.
Moreover, Nasaif et al. found in his study conducted in The Kingdom of Bahrain, which assessed the symptoms and risk factors of CRC that there were poor knowledge and awareness among Bahrainis about the signs and risk factors of CRC [12]. Considering screening tools, 45.8 % of participants thought that X-ray has a role in screening of CRC, while 20.9 % knew that microscopic stool examination and only 9.5 % choose a colonoscope as tools in screening CRC. On the other hand, 18.9% thought that barium study and 4.8% thought that ultrasound is a screening tool ( Figure 5). In the study of Mona Abdullah Alsayed, she found that the most critical methods of examining their participants: a colonoscopy, a CT scan of the colon, and a blood test revealed faecal [9]. Surprisingly, we did not find any correlation between gender and level of education, especially considering risk factors and symptoms. Therefore, we should aim the further educational programs to all populations and demographics Qassim region. Furthermore, many methods can be applied to increase the knowledge of the public about the CRC including providing health fairs to encourage public for early CRC screening [13], raise awareness of the public about the seriousness of CRC and how is common in Saudi Arabia than other countries especially in al Qassim region to decrease their hesitation (hesitancy) to go to clinics. Besides that, workplace screening to increase the screening rate of CRC in the different areas of Al-Qassim can be applied. Furthermore, according to our results and the results of previous studies, we found that Saudi Arabian in Qassim region lack some knowledge about CRC and thus a need for national screening program should be considered. Still, this study is limited because of gender bias as most of the sample were female which however indicate that females are more interested in filling this type of questionnaire than male, this predominance of female makes the study not the meaning of the real population. Furthermore, most of the study was from the younger people; however, there is a proper distribution among all ages. Finally, while this study should cover the region of Qassim, it is found that most of the sample was from specific areas rather than others. Therefore, it may not be represented in the real population in Qassim region. On the other side, the study covers large sample, including all age levels, different educational and occupational levels.
In conclusion, we found that the mean score of knowledge among the public in the Qassim region about CRC was 3.5573 ± 1.2664. the most symptoms related to CRC identified by the participants were blood in stool and abdominal pain, while the history of familiar CRC was the most known risk factors. There is a lack in the Knowledge about CRC among the public in Qassim region, and there   is a demand for more investigation to assess the reasons behind this profound knowledge, and to raise awareness of these symptoms, it is crucial to conduct a health promotion program to promote the public to seek medical attention.
