(1) Background: COVID-19 has become a worldwide public health problem. No previous study has investigated factors associated with COVID-19 knowledge, attitude, and practice (KAP) after completely lifting the curfew in all Saudi Arabia regions and cities. Therefore, adequate knowledge, a positive attitude, and correct control of COVID-19 are essential to eradicate the disease. Hence, this study aims to assess factors associated with KAP of COVID-19; (2) Methods: This cross-sectional web-based survey was performed with the participation of 4305 individuals aged over 15 years living in Saudi Arabia from 11 to 19 August 2020. They were included using the snowball sampling method; (3) Results: Of the 4305 participants, 94.9% were Saudis, 60% females, and 45.4% were in the age group of 20–34 years, 61.7% married, and 49.3% from the Eastern Province of Saudi Arabia. Most of the participants demonstrated good KAP levels (89.6%, 87.2%, and 87.2%) towards the COVID-19 pandemic, respectively. In addition, most of the participants (85.8%) used the internet and social media as a source for COVID-19 information (4) Conclusions: The finding showed that most of the participants demonstrated good knowledge of COVID-19, positive attitudes, and demonstrated good practices for preventing the spread of disease infection.

Background: Antimicrobial resistance is a global issue that causes significant morbidity and mortality. Therefore, this study aims to assess knowledge, attitudes, and practices (KAP) of the general Saudi populations toward antibiotics use.Design and methods: A cross-sectional, anonymous online survey was conducted from January 1 to May 11, 2020, across five major regions of Saudi Arabia. Participants (aged ≥18 years) were invited through social media to complete an online self-structured questionnaire. All data were analyzed by Statistical Package (SPSS v.25). Descriptive statistics, Pearson's Chi-squared, t-tests, one-way analysis of variance (ANOVA), and Pearson correlation analyses were conducted. Results: Out of 443 participants, the majority (n=309, 69.8%) were females, 294 (64.4%) were married, 176 (39.7%) were 25-34 years of age, 338 (76.3%) were living in the Eastern Province, 313 (70.7%) had college or higher education, 139 (31.4%) were not working, and 163 (36.8%) had a monthly income of USD 800-1330. Overall, most participants demonstrated good knowledge and practice (88% and 85.6%, respectively).  However, 76.8%had inadequate attitude score levels towards antibiotics use. Of all the respondents, 74.9% knew that not completing a full course of antibiotics may cause antibiotics resistance, 91.33% did not agree that antibiotics should be accessed without a prescription, and 94.04% will not hand over leftover antibiotics to family members. Factors associated with adequate knowledge were female, medical jobs, and higher income (p<0.05). Conclusions: Our findings revealed that while most participants were aware of antibiotics use and demonstrated good knowledge, good practices, they had negative attitudes towards antibiotics use.

Objective: This study aimed to evaluate the impact of cigarette smoking and health-related quality of life among Saudi secondary vocational students during the COVID-19 pandemic. Methods: A convenience sample of 328 answered a web-based self-administered questionnaire based on the Youth Risky Behavior Monitoring System (YRBSS) plus the Short Form 12 (SF-12) were included in the study. The target population included all Saudi students enrolled at the Secondary Industrial Institute in Dammam, Saudi Arabia, during December 2020 and February 2021. Results: Out of the total of 328 male participants, representing a response rate of 38.59%, the highest percentage of respondents were in the first year (45.4%), the mean age of the participants was 17.73 years with a standard deviation (SD) of 1.85 years. The prevalence of current smokers, past smokers, and never smokers accounted for 30.2%, 21.3%, and 48.5%, respectively. First-year students reported relatively high levels of smoking prevalence and low physical scores of healthrelated quality of life (HRQoL). The overall mean of HRQoL of current smokers, past smokers, and never smokers accounted for 58.60, 58.38, and 63.66, respectively. In addition, current smokers reported a relatively low physical score of HRQoL 55.73. Conclusion: This is the first report to explore the impact of smoking on HRQoL of Secondary Industrial Institute students in Saudi Arabia during the COVID-19 pandemic. The results indicate that smoking has a negative impact on the quality of life of vocational students. Therefore, a health strategies plan may be developed to improve the quality of life for vocational students in Saudi Arabia.

(1) Background: Even though irritable bowel syndrome (IBS) is not life-threatening, it can have a significant impact on a patient's daily activities and quality of life. Studies indicate that IBS is more prevalent in women than in men. The mechanism, etiology, and signs of IBS are not well understood, but there is evidence that gender and age is a biological characteristic that affects these subjects. This influence on the quality of life of Saudi adults by gender and age has not previously been compared. (2) Methods: A snowball sampling techniques of 279 people in Qatif, Saudi Arabia, is surveyed online to assess health-related quality of life (HRQoL). The Short SF-36 was self-administered to assess HRQoL; logistic regression models, Mann-Whitney, and the Kruskal-Wallis were used. SPSS version 23.0 was used to store and analyze all data. (3) Results: The prevalence of IBS among Saudi adults was 17.6%. IBS has a statistically significant association with age and gender which is more common among older women. IBS participants have poorer HRQoL than the overall population, particularly in Physical Component Score (PCS). (4) Conclusions: IBS is more prevalent among Saudi adults in Qatif and has a significant negative impact on the HRQoL, particularly among elderly women.
