Background Tobacco use remains a significant global public health challenge, with a noticeable increase in the consumption of oral smokeless tobacco (OST) in response to stricter smoking regulations. Despite recognizing the health risks associated with OST, there is limited research on the factors influencing individuals’ intention to quit, particularly in Saudi Arabia. The study’s aimed to investigate OST behavior and the demographics and psychosocial determinants of the intention to quit among OST users. Methods A cross-sectional analytical study was conducted, utilizing a convenient sample of current OST users. A structured questionnaire was developed informed by the World Health Organization’s Global Adult Tobacco Survey, literature review, and experts’ consultation. The questionnaire evaluated demographics, tobacco behaviors, perceived control beliefs, subjective norms, and intention to quit. Data were collected through an online platform and subsequently analyzed using SPSS (version 29). Descriptive and inferential statistics were done including multinomial logistic regression to identify which factors significantly predicted the intentions to quit. Results A total of 341 OST users participated (mean age: 39.1 years; 58.4% male; 61.5% married). While 46% expressed a positive intention to quit, demographic factors alone were not significant predictors. Key predictors included OST use for over 15 years, past quit attempts, dentist advice, subjective norms, and perceived control. Gender moderated these effects: females receiving quit advice were 4.48 times more likely to intend to quit, while males showed increased quit intention with stronger subjective norms (AOR = 0.547). Conclusions The findings of this study revealed key determinants influencing OST users’ intention to quit: the longer duration of OST use, prior attempts, dentist quit advice, perceived control beliefs, and subjective norms. Future research is needed to explore gender differences concerning the effectiveness of dentist’s advice and subjective norms.

Objective We aimed to explore dentists’ perceptions toward the implementation of a comprehensive intervention (ISAC) for the early detection and prevention of oral cancer in a dental clinic. Methods The ISAC intervention was presented to ten purposefully sampled dentists in Jazan Dental School (JDS). Participating dental interns were asked to practice the ISAC intervention whilst thinking aloud. A semi-structured interview technique was used to allow free expression of participants’ perceptions related to the ISAC intervention and to control the flow of topics. Fleuren’s framework theory informed the analysis. The interviews were transcribed verbatim and analyzed using the deductive-inductive framework analysis. Results Practicing the ISAC intervention was perceived to enhance the early detection and prevention of oral cancer. Serving community needs and engaging community groups were perceived to be related to a high relevance and compatibility of the ISAC intervention. Being a comprehensive intervention with well-defined objectives and being built on relevant data from the participants’ community and having dentists as a target group were the perceived relative advantages of the ISAC intervention compared to other programs. A supportive environment, gender-concordance, use of regional trainers, standard examination form and collaboration with other sectors were perceived to be the facilitators. Competition with clinical time, use of different examination forms and low organizational leader interests were perceived as impeding factors against effective implementation in a real-world context. Reward, easy to practice, feeling confidence and satisfaction, advertisement as well as use of a role model approach were perceived to be motivating factors. Conclusions Integrating data from representers of different participant groups during intervention conceptualization and development are critical for the intervention compatibility and acceptability. The study findings showed the opportunities of intertwining the intrinsic motivators of satisfaction and altruism existing in the target group and the extrinsic motivator of official diagnostic skill, certification that may boost and sustain the behavior change. Intervention features that influence perceived relevance, compatibility, relative advantage and motivation may be of great importance for intervention practice.

Background In Ethiopia, milk production and handling practices often lack proper hygiene measures, leading to the potential contamination of milk and milk products with Staphylococcus aureus ( S. aureus ), including methicillin-resistant strains, posing significant public health concerns. This study aimed to investigate the occurrence, antimicrobial susceptibility profiles and presence of resistance genes in S. aureus strains isolated from milk and milk products. Methods A cross-sectional study was conducted in the Arsi highlands, Oromia, Ethiopia from March 2022 to February 2023. A total of 503 milk and milk product samples were collected, comprising 259 raw milk, 219 cottage cheese, and 25 traditional yogurt samples. S. aureus isolation and coagulase-positive staphylococci enumeration were performed using Baird-Parker agar supplemented with tellurite and egg yolk. S. aureus was further characterized based on colony morphology, Gram stain, mannitol fermentation, catalase test, and coagulase test. Phenotypic antimicrobial resistance was assessed using the Kirby–Bauer disc diffusion method, while the polymerase chain reaction (PCR) was employed for confirming the presence of S. aureus and detecting antimicrobial resistance genes. Results S. aureus was detected in 24.9% of the milk and milk products, with the highest occurrence in raw milk (40.9%), followed by yogurt (20%), and cottage cheese (6.4%). The geometric mean for coagulase-positive staphylococci counts in raw milk, yogurt, and cottage cheese was 4.6, 3.8, and 3.2 log 10 CFU/mL, respectively. Antimicrobial resistance analysis revealed high levels of resistance to ampicillin (89.7%) and penicillin G (87.2%), with 71.8% of the isolates demonstrating multidrug resistance. Of the 16 S. aureus isolates analyzed using PCR, all were found to carry the nuc gene, with the mecA and blaZ genes detected in 50% of these isolates each. Conclusion This study revealed the widespread distribution of S. aureus in milk and milk products in the Arsi highlands of Ethiopia. The isolates displayed high resistance to ampicillin and penicillin, with a concerning level of multidrug resistance. The detection of the mecA and blaZ genes in selected isolates is of particular concern, highlighting a potential public health hazard and posing a challenge to effective antimicrobial treatment. These findings highlight the urgent need to enhance hygiene standards in milk and milk product handling and promote the rational use of antimicrobial drugs. Provision of adequate training for all individuals involved in the dairy sector can help minimize contamination. These measures are crucial in addressing the threats posed by S. aureus , including methicillin-resistant strains, and ensuring the safety of milk and its products for consumers.

Jazan region of Saudi Arabia has a high prevalence of oral cancer: 35% of cases. However, little is known about the view of dentists and dental students on possible factors that contribute to this high rate with scarce efforts regarding prevention. The study investigated possible factors related to oral cancer as perceived by dentists and dental students, using a qualitative approach. Six focus groups conducted in Jazan Dental School (JDS) and participants included dental students, interns, faculty members, and key decision-makers. All participants acknowledged oral cancer a serious public health issue in Jazan affecting all ages. The majority thought that tobacco is a major risk factor in this region, which can easily be obtained by individuals of any age or gender. Further, formal dental education in the country is not focusing on the local related risk factors. Participants agreed that practicing oral cancer examination and its risk factors education is related to clinicians’ attitude and skills. Several participants declared that no organized effort established toward oral cancer and its risk factors in the region. Cultural acceptance of oral cancer risk factors was mentioned as one of the challenges for patients. The findings indicate that dental education and training at JDS are not focusing on necessary related oral health issues and their risk factors in the community. Also, it casts a new light on the fact that dentists are not educating their patients because they lack the knowledge and the skill of health education and patients’ communication methods.

The education sector experienced substantial impacts during the COVID-19 pandemic resulting from worldwide restrictions. To examine differences in the sleep patterns, sexual activity, screen use, and food intake of students and non-students during the COVID-19 pandemic. This was a global cross-sectional study conducted in the second half of 2020 using multiple social media platforms to recruit study participants globally. A close-ended questionnaire was administered anonymously in English, French, Spanish, Portuguese, and Arabic to adults ages 18 and older. The outcome variables considered in analyses were changes in sleep pattern, sexual activity, screen use, and food intake. The explanatory variable was student status categorized as students vs. non-student. T-test, chi-square, and Mann Whitney U tests were used to assess differences between student and non-student populations. One logistic regression model was built for each outcome variable. Country of residence and country income level were included in the adjusted models. There were 17,008 participants of which 3,793 (22.3%) were students. Of the total sample, 4,889 (28.7%) reported changes in sleep, 4,642 (31.8%) reported increases in sexual activity, 10,278 (70.7%) reported increases in screen use, and 5,662 (40.2%) reported increases in food intake during the pandemic. Compared to non-students, students had significantly higher odds of reporting changes in sleep (AOR = 1.52), increases in sexual activity (AOR = 1.79), and increases in screen use (AOR = 1.36) but lower odds of reporting increase in food intake (AOR = 0.87). Students displayed higher risk of experiencing changes in sleep, sexual behavior, and screen use during the COVID-19 pandemic. This has the potential to lead to broader adverse effects on students' overall wellbeing. The findings and implications raise further obligations on the education sector to put extra-curricular support systems in place that address COVID-19 related behavior changes that have the potential to adversely impact students' wellbeing.

Background Health behaviours are influenced by individual characteristics including age, gender, education and economic level. This study aimed to assess the associations between individual-level determinants and adherence to COVID-19 preventive measures. Methods We performed secondary analyses of international data collected using an online survey during the first wave of the COVID-19 pandemic between June and December 2020. The dependent variables were self-reported adherence to COVID-19 preventive measures (wearing of face masks, frequent washing/sanitizing of hands, physical distancing, working remotely). The independent variables were age, sex at birth (female vs male), having a chronic disease related elevated risk for severe COVID-19 (none/little, might be at increased risk, at increased risk), educational level completed (no formal education, primary, secondary vs college/university) and employment status (retiree, students, not employed vs employed). Four multivariate logistic regression analyses were conducted to determine the associations between the dependent variables and independent variables. Interaction terms with country-income level were tested in regressions to explore its moderating effect. Results Out of 16,866 respondents, 12,634 (74.9%) wore masks or face coverings, 12,336 (73.1%) washed or sanitized their hands frequently, 11,464 (68.0%) reported adherence to physical distancing and 5,646 (33.5%) worked remotely. In adjusted analyses, increased age, college/university education, employment, and having risks for severe COVID-19 were associated with significantly higher odds of adhering to COVID-19 preventive measures. Retirees and students had lower odds of adhering to COVID-19 prevention measures than employed individuals. Males had significantly lower odds of wearing face masks (AOR: 0.901), frequent washing/sanitizing hands (AOR: 0.774) and working remotely (AOR: 0.875) compared to females. Country-income level generally moderated the above relationships such that the associations disappeared in lower income countries. Conclusion The study findings suggest that the individual socio-demographic factors—age, sex, employment status, education status and having a chronic disease – influence adherence to COVID-19 preventive measures. Findings further reiterate the need for health education and health promotion campaigns on preventive health measures to focus on subpopulations, such as younger males, students and retirees, that require targeted or unique messaging.

The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables—COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60–3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20–0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.

Background/Objectives: Artificial intelligence is revolutionizing healthcare across multiple areas, and periodontology is no exception to this emerging trend. This systematic study sought to rigorously assess the applicability and efficacy of artificial intelligence (AI) models in the diagnosis, classification, and prediction of periodontal diseases. Methods: A web-based search was performed across many reputable databases, including PubMed, Scopus, Embase, Cochrane, Web of Science, Google Scholar, and the Saudi Digital Library. Articles published between January 2000 and January 2025 were included in the search. Following the application of the inclusion criteria, 33 publications were selected for critical analysis utilizing QUADAS-2, and their certainty of evidence was evaluated using the GRADE technique. Results: The primary applications of AI technology include the diagnosis, classification, and grading of periodontal diseases; diagnosis of gingivitis; evaluation of the radiographic alveolar bone level and degree of alveolar bone loss; and prediction of periodontal disease risk. The AI models utilized in these studies outperformed current clinical methods in diagnosing, classifying, and predicting periodontal diseases, demonstrating a superior level of precision and accuracy. Their accuracies ranged from 73% to 99.4%, their sensitivities from 75% to 100%, and their precisions from 56% to 99.5%. Conclusions: AI has a lot of potential to help with periodontal diagnosis and risk assessment. Its performance is often similar to or better than that of traditional clinical approaches. But before it can be used widely in clinical settings, problems with the quality of the dataset, its generalizability, its interpretability, and its acceptance by regulators must be solved. AI should be seen as a tool that helps doctors make better decisions and not as a way to replace their knowledge and skills.

Background Most diagnosed oral cancer cases in Saudi Arabia are in the Jazan region. A common type of smokeless tobacco \"Shammah\" is prevalent in this region. This study aimed to gain an in-depth understanding of the possible psychosocial determinants of Shammah consumption among adult Shammah users in Jazan region. Methods A qualitative study was conducted by means of one-on-one interviews among thirty adult Shammah users. Participants were recruited by means of a purposive sampling technique. Data were collected using a semi-structured interview guide utilizing face-to-face and phone-call interviews. Thematic analysis with hybrid approach was used to analyze the dataset. Results Twenty-four sub-codes within four overarching themes were generated. Participants revealed uncertainty related to Shammah composition, how to quit knowledge and Shammah prevention/cessation programs. Shammah use identified as a normal phenomenon in society. Its use was frequently reported in participants’ close network but most users faced family and peers’ disapproval. Some users expressed joy, happiness and focused when using Shammah. Others were disgusted or neutral. Many users believed Shammah causes cancer and tears oral tissues. Others believed it relieves toothache or has no effect. Majority of users were confident to quit and recalled some quitting aids. Toothache, craving, drinking tea and chewing Khat (leaves of Catha edulis plant that causes moderate euphoria) perceived to be triggers to use Shammah. Availability of Shammah, withdrawal symptoms, stress, lack of support, seeing others using Shammah, losing part of routine and toothache were barriers to quit. Conclusions Shammah use was associated with uncertainty about Shammah composition and quitting knowledge, social acceptability, influence from family/friends, a range of positive and negative attitudinal beliefs toward its use and high quitting efficacy beliefs. Future interventions targeting Shammah should address the acknowledged triggers and barriers in the present study including the dual use of Shammah and Khat.

Despite free health care services in Saudi Arabia, the prevalence of caries in children is substantially greater in comparison to other high-income countries. Dental fear in children may be an important issue that needs attention. Therefore, the aim was to investigate the role of dental fear in predicting untreated dental caries in schoolchildren. This analytical cross-sectional study included children aged 8–10 years residing in Saudi Arabia. Dental status via oral examinations was surveyed with the WHO standardized chart and the Children Fear Survey Schedule—Dental Subscale was used to score dental fear. Descriptive, binary, and multivariable logistic regression analyses were performed to report the findings at 5% statistical significance. Overall, there were 798 schoolchildren with an average fear score of 36. Nearly 70.4% reported fear of someone examining their mouth. About 76.9% had at least one carious tooth in their oral cavity. Children with dental fear were 1.8 times (OR = 1.80; 95% CI = 1.26, 2.56) more likely to have at least one untreated carious tooth in their oral cavity than those who did not express fear during oral examinations and dental procedures. Thus, the current study concludes that fear of dentists and dental treatment procedures successfully predicts untreated carious teeth in schoolchildren.
