Background: Lung cancer (LC) is the most common cause of cancer-related deaths worldwide. With lung cancer often diagnosed at advanced stages, understanding the local population’s awareness levels is crucial for designing effective preventive strategies. By identifying gaps in knowledge, the research aims to inform targeted health education efforts, optimize resource allocation, influence policy development, and contribute to the limited body of research on lung cancer awareness in the region, ultimately fostering improved public health outcomes. Methods: This was a cross-sectional observational study conducted in Jazan region, Saudi Arabia, from July 2022 to June 2023, 671 participants over 18 years old, encompassing both genders, were gsurveyed. Data was collected through a questionnaire covering sociodemographic characteristics and LC-related awareness. SPSS 23 was used for analysis. Factors associated with knowledge scores were explored using independent t-tests and ANOVA, with the Tukey post-hoc test identifying specific group differences. Results: The study included 671 participants, most participants were between 18 and 35 years (73.5%), with 38.5% males and 61.5% females. Lung cancer (LC) awareness was high (95.1%), with 4.9% reporting a family history. Knowledge assessment revealed a mean score of 14.66, with 41.6% having low, 49.5% moderate, and 8.9% high knowledge levels. Correct responses were notable for recognizing LC as a common cancer, a leading cause of death, and associating smoking and shisha with risk. Symptoms were well identified. Screening awareness was at 63.5%, with 78.8% willing to undergo tests if at risk. Age, marital status, and occupation were associated with knowledge, while factors like gender, nationality, residency, education, income, and smoking status showed no significant associations. Conclusion: The findings indicate that there are knowledge gaps related to LC and its screening in Jazan region in Saudi Arabia. Effective awareness programs targeting specific sociodemographic groups are needed to improve the early detection and outcomes.

Background and Objectives: This study aimed to determine the prevalence of overweight, obesity, and the associated risk factors among medical students at Jazan University in Saudi Arabia. Materials and Methods: A cross-sectional study was conducted among 228 medical students from their second to sixth academic years at the Faculty of Medicine, Jazan University. A self-administered questionnaire was used to collect data regarding sociodemographic characteristics, physical activity, dietary habits, comorbidities, medication use, family history, and lifestyle factors. Anthropometric measurements including height, weight, and waist circumference were recorded. Chi-square test and binary logistic regression were used to identify the risk factors associated with obesity. Results: The prevalence of overweight and obesity among the participants was 13.3% and 15%, respectively. Hence, the combined prevalence of overweight and obesity is 28.3%. The mean weight was 63.39 ± 18.93 kg, and the mean height was 163.48 ± 9.78 cm. On the other hand, 17.3% of participants were underweight, whereas 54.4% had normal BMI. Most of the participants (61%) did not engage in regular exercise. A high proportion consumed fruits (82.9%) and vegetables (58.8%) 3 or fewer days per week, and 84.2% consumed 3 or fewer meals per day. Fast-food consumption more than 3 days per week was reported by 42.1% of participants. Obesity was not significantly associated with sociodemographic factors, physical activity, dietary habits, comorbidities, medication use, or family histories. However, those with a monthly family income of SAR 15,000–24,999 had significantly lower odds of obesity than those in the lowest income group (OR 0.230, p = 0.045). Conclusions: The prevalence of overweight and obesity among medical students at Jazan University is high. Although no significant associations were found between obesity and most risk factors, this study highlights the need for interventions that promote healthy lifestyles among medical students. Further research is needed to identify effective strategies for preventing and managing obesity in this population.

Background: Obesity is a global health crisis with a rapidly increasing prevalence among university students. Medical students are a unique population that may be at a higher risk of obesity due to the demanding nature of their studies and the associated stress. Objective: This study aimed to determine the prevalence of overweight, obesity, and the associated risk factors among medical students at Jazan University in Saudi Arabia. Methods: A cross-sectional study was conducted among 228 medical students from their 2nd to 6th academic years at the Faculty of Medicine, Jazan University. A self-administered questionnaire was used to collect data regarding sociodemographic characteristics, physical activity, dietary habits, comorbidities, medication use, family history, and lifestyle factors. Anthropometric measurements including height, weight, and waist circumference were recorded. Chi-square test and binary logistic regression were used to identify the risk factors associated with obesity. Results: The prevalence of overweight and obesity among the participants was 13.3% and 15% respectively. Hence, the combined prevalence of overweight and obesity is 28.3%. The mean weight was 63.39 ± 18.93 kilograms, and the mean height was 163.48 ± 9.78 centimeters. On the other hand, 17.3% of participants had underweight whereas 54.4% had normal BMI. Most of the participants (61%) did not engage in regular exercise. A high proportion consumed fruits (82.9%) and vegetables (58.8%) 3 or fewer days per week, and 84.2% consumed 3 or fewer meals per day. Fast food consumption more than 3 days per week was reported by 42.1% of participants. Obesity was not significantly associated with sociodemographic factors, physical activity, dietary habits, comorbidities, medication use, or family histories. However, those with a monthly family income of 15,000-24,999 riyals had significantly lower odds of obesity than those in the lowest income group (OR 0.230, p = 0.045). Conclusion: The prevalence of overweight and obesity among medical students at Jazan University is high. Although no significant associations were found between obesity and most risk factors, this study highlights the need for interventions that promote healthy lifestyles among medical students. Further research is needed to identify effective strategies for preventing and managing obesity in this population.

Background: Hepatitis B virus (HBV) infection poses a persistent global public health challenge, with substantial associated morbidity, mortality, and healthcare utilization. Although Saudi Arabia has maintained a national HBV vaccination program for decades, population-level data on hepatitis B infection knowledge, attitudes, and practices (KAP) remain scarce and regionally limited. This study aimed to comprehensively assess KAP toward hepatitis B infection prevention among the general adult population across all regions of Saudi Arabia and to identify independent sociodemographic predictors of each domain to inform targeted healthcare interventions. Methods: This nationwide cross-sectional study used a convenience sampling approach and a validated, self-administered questionnaire disseminated via online social media platforms across all regions of Saudi Arabia between August 2024 and February 2025. KAP was assessed using an instrument adapted from Haq et al. (Cronbach’s α = 0.70). Good knowledge was defined as a score ≥11/20 (≥55%), positive attitude as ≥5/7 (≥71.4%), and good practice as ≥6/8 (≥75%). Multivariable linear regression was used to identify independent predictors, adjusting for sociodemographic covariates. Results: A total of 1278 participants were included (mean age 30.3 ± 12.4 years; 60.9% female). Overall, 54.2% demonstrated good knowledge, 68.5% demonstrated positive attitudes, and only 16.2% exhibited good preventive practices. Screening (14.6%) and vaccination uptake (26.5%) were markedly low. Educational program participation was the strongest modifiable predictor across all three domains: knowledge (β = +1.89, 95% CI: 1.20–2.58, p < 0.001), attitude (β = +0.47, 95% CI: 0.25–0.69, p < 0.001), and practice (β = +1.43, 95% CI: 1.09–1.77, p < 0.001). Healthcare sector employment was independently associated with higher KAP scores across all domains. Income demonstrated a positive dose–response relationship with knowledge and practice outcomes. Polygyny was associated with lower scores across all three domains. Conclusions: Despite moderate knowledge and generally favorable attitudes, preventive practices remain critically deficient, revealing a persistent knowledge–practice gap. Integrated, behavior-oriented interventions targeting modifiable determinants, particularly health education, income disparities, and stigma, are urgently needed to support progress toward national and global HBV elimination targets.

Background/Objectives: Topical corticosteroids (TCS) are a cornerstone of dermatological treatment for inflammatory skin conditions; however, irrational fear of their use known as corticophobia undermines adherence and worsens clinical outcomes. This study investigated the prevalence of TCS-related concern and phobic behaviors among the general population in Saudi Arabia and identified factors associated with TCS-related concern and phobic attitudes. Methods: A cross-sectional study was conducted between October and December 2025 using an online self-administered questionnaire distributed via social media platforms among a non-probability convenience sample across multiple geographic zones of Saudi Arabia. A total of 481 participants were enrolled. Descriptive statistics summarized demographic and clinical characteristics. Chi-square and Fisher’s exact tests were used to examine differences in proportions between categorical variables and TCS concern, while independent-samples t-tests and one-way ANOVA compared mean phobia scores across subgroups. Results: Of 481 participants, 254 (52.8%, 95% CI 48.3–57.2) expressed concern about TCS use. The predominant reason for refusing prescribed TCS was fear of side effects (93.5%). Phobic behaviors included fear of long-term use (54.2%) and fear of application to sensitive skin areas (63.0%). On the Likert phobia-scale item, 237 (49.8%) totally agreed they would use TCS if prescribed; a separate dichotomous behavioral-intention item, administered only to non-current users (n = 308), showed that 201 (65.3%) would accept TCS if prescribed and 107 (34.7%) would refuse. Concern was significantly more prevalent among females (58.1%, BH-adj p = 0.005), married participants (61.7%, BH-adj p = 0.010), and those refusing prescribed TCS (77.6%, BH-adj p < 0.001). Mean phobia scores (theoretical range 7–28) were significantly higher among females (20.43 ± 4.06 vs. males 18.84 ± 4.68, p < 0.001), participants with Diploma-level education (21.64 ± 3.12, p < 0.001 across education strata), widowed/divorced individuals (21.82 ± 3.57, p = 0.008), and residents of the Southern (20.47 ± 3.99) and Northern (21.40 ± 3.34) regions (p = 0.002 across regions). Conclusions: TCS-related concern was expressed by over half the participants in this social media-recruited sample, posing a substantial barrier to effective dermatological care. Side-effect concern was the most frequently reported reason for refusing prescribed TCS. In adjusted analyses, female sex was the most consistent independent correlate of TCS-related concern and higher phobia score; married status was independently associated with greater concern. These associations should be replicated in probability-based samples before subgroup-targeted interventions are designed. Conclusions: TCS-related concern was prevalent (52.8%) among adults in Saudi Arabia and represented a substantial barrier to dermatological care. Female sex and married status were independently associated with greater concern. Clinicians should proactively address TCS misconceptions during dermatological consultations to improve treatment adherence.
