Background: Obesity rates among Saudi adolescents are increasing, with regional variations highlighting the need for tailored interventions. School-based health programs in Saudi Arabia are limited and often emphasize weight and body size, potentially exacerbating body image dissatisfaction. There is limited knowledge on the feasibility of non–weight-centric educational programs in Saudi Arabia and their effects on health behaviors and body image. Objectives: This study aimed to (1) assess the prevalence of obesity using BMI-for-age z score (BAZ) and fat percentage among Saudi adolescents; (2) evaluate key health behaviors, cardiovascular fitness, and health literacy; and (3) assess the feasibility and impact of a low-intensity, non–weight-centric educational intervention designed to improve knowledge of macronutrients and metabolic diseases, while examining its safety on body image discrepancies. Methods: A quasi-experimental, pre-post trial with a parallel, nonequivalent control group design was conducted among 95 adolescents (58 boys and 37 girls; mean age 16.18, SD 0.53 years) from 2 public high schools in Medina City, Saudi Arabia. Participants were randomly assigned to either the weight-neutral Macronutrient + Non-Communicable Diseases Health Education group or the weight-neutral Macronutrient Health Education group. Anthropometry (BAZ and fat percentage), cardiovascular fitness, physical activity, and eating behaviors were measured at baseline. Independent t tests and χ² tests were conducted to compare group differences, and a 2-way mixed ANOVA was used to evaluate the effect of the intervention on macronutrient knowledge and body image discrepancies. A total of 69 participants completed the postintervention assessments. Results: The prevalence of overweight and obesity based on BAZ was 37.9% (36/95), while 50.5% (48/95) of participants were classified as overfat or obese based on fat percentage. Students with normal weight status were significantly more likely to have had prior exposure to health education related to metabolic diseases than students with higher weight status (P=.02). The intervention significantly improved macronutrient-metabolic knowledge (F_1,64=23.452; P<.001), with a large effect size (partial η²=0.268). There was no significant change in students’ body image from pre- to postintervention (P=.70), supporting the safety of these weight-neutral programs. The intervention demonstrated strong feasibility, with a recruitment rate of 82.6% and a retention rate of 72.6%. Conclusions: This study reveals a high prevalence of obesity among Saudi adolescents, particularly when measured using fat percentage. The significant improvement in knowledge and the nonimpact on body image suggest that a non–weight-centric intervention can foster better health outcomes without exacerbating body image dissatisfaction. Region-specific strategies that prioritize metabolic health and macronutrient education over weight-centric messaging should be considered to address both obesity and body image concerns in adolescents.

Background/Objectives: Tranexamic acid (TXA) is a synthetic antifibrinolytic agent that inhibits plasminogen activation, thereby reducing bleeding. The aim of this systematic review was to investigate its role in aneurysmal subarachnoid hemorrhage (SAH)—a condition indicated by bleeding between two layers of brain tissue—to stop rebleeding and improve patient outcomes. Methods: We conducted a systematic review and meta-analysis of randomized controlled trials from 1981 to 2024, focusing on the efficacy and safety of TXA in treating aneurysmal SAH (PROSPERO registration: CRD42024504834). Our comprehensive search of the PubMed and Cochrane Library databases identified studies assessing TXA at dosages of 3 to 6 g per day and examining outcomes such as rebleeding incidence, mortality, thromboembolic events, and other adverse effects. Results: From six included studies involving 2990 patients, the meta-analysis showed TXA largely lowered rebleeding risk (OR 0.54 95% CI 0.43–0.68; p < 0.00001), yet mortality rates were not largely different between the TXA group (385 out of 1201), and the control group (344 out of 1193) (OR 1.18 95% CI 0.98–1.40; p = 0.07). Likewise, there were no large differences in the occurrence of cerebral ischemia and blood clot-related events between the groups. Conclusions: TXA effectively reduces the risk of rebleeding in SAH patients, but does not significantly alter mortality or the incidence of thromboembolic complications. These findings back the careful use of TXA and demonstrate the need for further research to better its clinical use and assess long-term impacts.
