BACKGROUND: There is a lack of data on Saudi domestic air travellers' understanding regarding COVID-19 and their attitude towards the COVID-19 vaccination. OBJECTIVES: This study aimed to assess Saudi domestic air travellers' understanding regarding COVID-19 and attitude towards mandating the COVID-19 vaccination for travellers. METHODS: A survey using a self-administered, structured, and closed-ended questionnaire was conducted among domestic air travellers in Saudi Arabia. Participants' socio-demographic information, travel history, health status, and attitudes and willingness to accept the COVID-19 vaccination were collected and analysed. RESULTS: Of the 2236 respondents who participated in the survey, 542 (24.25%) had a history of COVID-19, 803 (35.9%) were exposed to a COVID-19 case, 1425 (63.7%) were concerned about catching COVID-19 during air travel, 796 (35.6%) thought the COVID-19 vaccination should be obligatory for travellers, 1105 (49.4%) thought it should be optional, and 335 (15.0%) thought the vaccination was unnecessary. Being of the male gender (adjusted odds ratio [aOR] 1.41, 95% confidence interval [95% CI] 1.14-1.69), being concerned about contracting COVID-19 (aOR 1.34, 95% CI 1.12-2.10) and frequent travelling (aOR 1.40, 95% CI 1.10-3.40) were predictors of vaccination uptake. CONCLUSION: This study demonstrates that although domestic Saudi travellers were concerned about COVID-19 infection, vaccine hesitancy was prevalent among them.

BACKGROUND: Khat is known to have a stimulating effect on the sympathetic nervous system by producing a temporary sensation of activeness and happiness, along with mood disturbance and anxiety. Despite growing evidence of the association between khat chewing and glycaemic control in patients with diabetes, the position of khat chewing in DM is not fully recognised. AIM: To evaluate the association of khat chewing with the risk of elevated blood glucose levels among patients with type 2 diabetes mellitus. METHOD: A web-based literature search was performed using the electronic databases PubMed, EMBASE and Google Scholar. Databases were searched for studies published about khat chewing and diabetes mellitus in the Jazan region, Saudi Arabia and Yemen. RESULT: Twenty-five published articles studying the relation between khat chewing and diabetes mellitus were identified, but only 10 studies reported an association between khat chewing and blood glucose levels and were included. CONCLUSION: Khat chewing increases fasting blood glucose, post-prandial blood glucose and HbA1c levels in patients with diabetes in the Jazan region, Saudi Arabia and Yemen.
