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 https://www.betsomnia-nl.nl/ projection (1.5 design effect). Verbal informed consent was obtained from all participants, detailing the study’s purpose, procedures, risks, and benefits. These deficiencies in health literacy and antibiotic education underscore the urgent need for targeted educational interventions .

• Logistic regression model was computed to identify predictors of inadequate knowledge, negative attitude, and poor practices towards antibiotics use.
• 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.
• A national study on Gram-positive bacteria in Saudi Arabia revealed alarming resistance trends.
• This study aimed to assess knowledge, attitudes, and practices toward AR among non-medical university students in Riyadh, Saudi Arabia, and to identify factors influencing antibiotic use.
• Sources of information about the participants’ antibiotic use.

Associated Data

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 for sustained antimicrobial stewardship efforts and strict enforcement of antibiotic regulations to mitigate the growing threat of AMR in the region.

3.2. Data Collection Instrument

• This study provides vital data for public health initiatives and informs effective strategies to promote responsible antibiotic use.
• Notably, the majority of participants were in the age group 19–20 years old (36.8%), unmarried (96.0%), female (60.0%), and of Saudi nationality (94.5%).
• Understanding public knowledge, attitudes, and practices regarding antibiotics is essential for developing effective strategies to combat AR .
• 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.
• 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.
• Age is one factor linked to less responsible antibiotic behaviors, suggesting certain groups are more prone to misuse.

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.
Proposed strategies include integrating AR education into university curricula, launching campus-wide campaigns (e.g., digital outreach, mandatory health literacy modules), and partnering with pharmacies to reinforce responsible practices. This suggests that the majority of participants had a moderate level of practice towards antibiotic use, similar to the reported findings from university student in Nepal and in line with the almost around the global average of 56%, according to the 2020 WHO survey . Overall, the study highlights the need for interventions to improve students’ understanding of AR and promote appropriate practices. However, nationality and university affiliation showed no significant associations across knowledge, attitude, or practice, with all p-values greater than 0.05. Specifically, 43% (289 out of 672) of the participants demonstrated an adequate understanding of antibiotic resistance, while the remaining 57% (383 out of 672) exhibited an inadequate knowledge of this topic. 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 .

Associated Data

This study provides vital data for public health initiatives and informs effective strategies to promote responsible antibiotic use. This study reveals a significant lack of knowledge and understanding about AR among non-medical university students. The Center for Disease Control and Prevention (CDC) and other global health agencies advocate for integrated public health strategies to fight MDROs, particularly among university students.

Among Staphylococcus aureus isolates, 32% were methicillin-resistant (MRSA), while Streptococcus pneumoniae demonstrated penicillin G resistance (33%) and erythromycin resistance (26%) .

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).
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.
When it came to the field of study, the majority were enrolled in business programs (34.1%). Notably, the majority of participants were in the age group 19–20 years old (36.8%), unmarried (96.0%), female (60.0%), and of Saudi nationality (94.5%). All the questionnaires were reviewed before entering the data into the analysis program.
Participants scoring above 60% were deemed to have adequate KAP, whereas those at or below this threshold were categorized as having insufficient understanding or behaviors in antibiotic use. Knowledge-related questions were scored with a binary system, where incorrect or uncertain (“don’t know”) responses received a score of 0, while correct answers were awarded 1 point. Domains with less than 0.07 were reviewed carefully, and targeted questions were modified or deleted accordingly. It was piloted among 5% of the sample (35 students). Data collection was conducted from 4 September to 19 October 2023 by a team of trained students from the College of Medicine at AlMaarefa University, who followed standardized protocols for accuracy and consistency. This in-person approach ensured direct participant engagement, comprehensive responses, and efficient data collection.

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.
