A convenience sampling was employed to select participants based on accessibility and willingness to participate on campus, continuing until the required sample size was met. The sample was then proportionally allocated to each university. A multistage sampling method was used, first stratifying Riyadh universities as public or private (three universities for each). This study adhered to strict ethical guidelines. These findings highlight the pressing need https://www.betsomnia-nl.nl/ for sustained antimicrobial stewardship efforts and strict enforcement of antibiotic regulations to mitigate the growing threat of AMR in the region.
Combining prevention and response interventions is essential for effective control in healthcare settings . Family/siblings or friends provided information for 7.0% (47 participants), while social media was a source for 6.8% (46 participants). Pharmacists were the second-most common source, consulted by 9.4% (63 participants). The mean knowledge score related to AR was 63.97 ≈ 64 (±8 SD, range ≈ 49). Sociodemographic characteristics of the participants.

• This study found that non-medical students at Riyadh universities demonstrate strong awareness of antibiotic use information sources, with 76% relying primarily on physicians—a rate markedly higher than the 38% observed among Malaysian university students .
• The effective sample size calculated was 334; however, a larger sample size of 501 students was eventually included in the study, yielding approximately 1.5 times the initial sample size projection (1.5 design effect).
• These behaviors increase the prevalence of resistant infections, leading to harder-to-treat diseases, higher healthcare costs, and increased outbreak risks on university campuses and within the broader community, posing a significant public health threat .
• Al Nasser et al. (2021) reported that while people may possess some knowledge about antibiotics, they often exhibit negative attitudes toward their use .
• The attitude and practice sections utilized a five-point Likert scale (strongly disagree to strongly agree), with responses scored from 1 (least appropriate) to 5 (most appropriate).
• Risky behaviors—such as self-medication and sharing antibiotics without prescriptions—were widespread, revealing a mismatch between partial awareness and actual practices 13,45,46,47,48,49.

Focusing on non-medical students is critical, as they represent a high-risk demographic for antibiotic misuse due to their lack of formal medical training, potential role in shaping public health behaviors, and limited awareness of AR consequences. Similarly, Mostafa et al. (2021) found that Egyptian university students demonstrated low health literacy and limited knowledge about antibiotics, increasing the likelihood of misuse . Understanding public knowledge, attitudes, and practices regarding antibiotics is essential for developing effective strategies to combat AR . The findings also reveal critical gaps in knowledge, attitudes, and practices among such students regarding antibiotic use. Overall, 77.3% demonstrated adequate knowledge, 67.4% positive attitudes, and 49.4% good practices toward antibiotic use.

Associated Data

• Methods A cross-sectional study was conducted among undergraduate students of the Faculty of Allied Health Sciences, Kwame Nkrumah University of Science and Technology, from May–August 2024.
• Additional questions assessed understanding of antibiotic side effects and the perceived efficacy of alternative medicine as a substitute.
• Focusing on non-medical students is critical, as they represent a high-risk demographic for antibiotic misuse due to their lack of formal medical training, potential role in shaping public health behaviors, and limited awareness of AR consequences.
• Attitudes toward antibiotic use were evaluated through twelve questions, including statements such as trusting a physician’s decision when choosing not to prescribe antibiotics and avoiding unnecessary antibiotic use.
• A literature review identified only three studies on antibiotic KAP among healthcare students 9,10,11, with no published research on non-medical university students in Saudi Arabia 28,29,30.
• For engineering students, who demonstrated higher baseline knowledge, introducing an elective course on antibiotic awareness could leverage their scientific literacy and problem-solving skills.
• Younger demographics, particularly university students, are globally recognized as high-risk groups for AR.

While our study primarily focused on university students within Riyadh, we acknowledge that nationality could indeed play a role. Students from literary fields were the most likely to have insufficient knowledge, attitudes, and practices, while those in science and engineering showed better outcomes. While overall awareness and behavior appear positive, nearly four in ten students lack proper understanding and engagement in AR practices. The study converted all antibiotic-related knowledge, attitude, and practice scores into percentages to standardize scoring and classify proficiency levels.

This disparity aligns with the observation that science and engineering students, benefiting from biology/microbiology-rich curricula and practical lab work, demonstrate enhanced antibiotic understanding and practices, thus contributing to improved public health literacy. This study used Pearson’s Chi-Square test to explore the relationship between antibiotic knowledge, attitudes, and practices and demographic factors, after confirming the test’s assumptions, notably that expected cell frequencies were above five. Logistic regression model was computed to identify predictors of inadequate knowledge, negative attitude, and poor practices towards antibiotics use. Data on knowledge, attitudes, and practices (KAP) regarding antibiotic use were collected via a structured, pretested questionnaire.

3.2. Data Collection Instrument

Additionally, many individuals discontinue antibiotics as soon as they feel better rather than completing the full course, further exacerbating AR risks. Al-Shibani et al. (2017) found that self-medication with antibiotics, even for minor illnesses like sore throats, is common in Riyadh . In 2018, the Saudi Ministry of Health (MOH) implemented a national policy requiring a prescription for all antibiotic sales in pharmacies, aiming to curb the misuse of antimicrobials. Antimicrobial resistance (AMR) poses an urgent global health crisis, contributing to approximately 700,000 deaths worldwide annually.
Initiating a health awareness campaign can assist legislators in making informed decisions to increase awareness. However, other studies from Italy and Nepal reported a very high level of knowledge to antibiotic use compared to our findings (84.8%, 94%) 30,31. This study aims to assess the level of awareness about AR. Sources of information about the participants’ antibiotic use. The primary source of information about antibiotic use among participants was their doctor, with 76.8% (516 participants) relying on this source (Figure 1).
Other statements examined self-medication behaviors, such as taking antibiotics based on past similar symptoms (e.g., toothache, gastrointestinal issues), using expired antibiotics, or discontinuing antibiotic courses prematurely upon feeling better. Additional statements addressed misconceptions, including the use of antibiotics for viral conditions (e.g., colds, flu), pain relief, fever reduction, and availability as over-the-counter drugs. The attitude section had a possible score range of 12–60, while the practice section ranged from 18–90. The attitude and practice sections utilized a five-point Likert scale (strongly disagree to strongly agree), with responses scored from 1 (least appropriate) to 5 (most appropriate). Three questions related to knowledge from the previous literature were found not appropriate to the local context and then not included in the final version of the questionnaire. A structured, paper-based, self-administered questionnaire—designed based on validated instruments from prior studies 16,31,34,35,36,37,38—was distributed as printed copies to target participants across multiple university campuses.

While these trends align with regional studies, they contrast with European data 15,16,40,50,51, likely reflecting cultural or institutional differences in health education. Factors such as cultural health beliefs, access to healthcare information, and variations in national health policies could all contribute to differences in awareness. In our Riyadh-based sample, participants were predominantly Saudi nationals, reflecting the local university demographics. Age is one factor linked to less responsible antibiotic behaviors, suggesting certain groups are more prone to misuse. Inappropriate antibiotic use, which is concerning, fuels antibiotic resistance. Since 2018, Saudi Arabia’s Ministry of Health has enforced regulations under the Health Practice Law, prohibiting pharmacists from dispensing antibiotics without a valid prescription from a licensed physician.
The aim of this study was to investigate the knowledge and awareness of appropriate antibiotic use among university students. The study highlights persistent knowledge gaps about AR among non-medical university students in Riyadh, despite moderate general awareness. This study found that non-medical students at Riyadh universities demonstrate strong awareness of antibiotic use information sources, with 76% relying primarily on physicians—a rate markedly higher than the 38% observed among Malaysian university students . Our study revealed a lack of knowledge regarding the safe use of antibiotics and inadequate medical practices related to their consumption among the population.

The datasets generated and/or analyzed during the current study are available from the corresponding author upon reasonable request. Targeted education is crucial to improve antibiotic awareness, especially among specific demographics. First, the reliance on self-reported data introduces risks of recall bias (e.g., inaccuracies in recalling past antibiotic use) and social desirability bias (over reporting adherence to guidelines), potentially compromising the validity of responses. These elements collectively strengthen insights into antibiotic awareness in an understudied demographic. Key strengths include a robust, gender-balanced sample of non-medical Riyadh students, enhancing statistical power and representativeness. The results advocate for tailored educational programs to enhance antibiotic awareness, particularly in demographics where age, gender, and academic discipline significantly influence outcomes.

2. Study Design and Settings

On the other hand, literary students had 52.2% lower odds of sufficient knowledge compared to sciences students. Notably, students aged 19–20 demonstrated the highest rates of insufficient knowledge and unsafe behaviors compared to other age groups. In terms of university affiliation, IMSU had the highest representation, with 54.0% of participants. Although the dataset contained minimal missing values, specifically about ten instances within the attitude assessment, mean imputation was employed to address these gaps. A 60% proficiency threshold—determined through pilot study analyses (mean and median of knowledge scores)—was adopted to assess adequacy across domains. Additional questions assessed understanding of antibiotic side effects and the perceived efficacy of alternative medicine as a substitute.
Al Nasser et al. (2021) reported that while people may possess some knowledge about antibiotics, they often exhibit negative attitudes toward their use . Antibiotic resistance has emerged as a critical global health challenge, driven by the widespread misuse and overuse of antibiotics, leading to the emergence of multidrug-resistant organisms (MDROs), which significantly complicate treatment options 1,2. Additionally, the absence of clinical validation—such as prescription audits or medical records—may lead to overestimations of appropriate antibiotic practices Such initiatives would bridge technical expertise with public health priorities, positioning engineers as advocates for antibiotic stewardship. Collaborations with medical or public health faculties could foster interdisciplinary solutions, empowering engineers to design innovations (e.g., wastewater treatment systems) that mitigate AMR risks. For engineering students, who demonstrated higher baseline knowledge, introducing an elective course on antibiotic awareness could leverage their scientific literacy and problem-solving skills.
Among Staphylococcus aureus isolates, 32% were methicillin-resistant (MRSA), while Streptococcus pneumoniae demonstrated penicillin G resistance (33%) and erythromycin resistance (26%) .
