Background: This systematic review examined the impact of road safety education (RSE) on lowering teenage traffic accidents and injuries in Southeast Asia based on existing literature. We evaluated the effectiveness of road safety education programs, contextual and cultural adaptations, the integration of practical training, implementation challenges, and the long-term impacts on changing teenage behaviour. Material and Methods: The study followed the guidelines of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). This involved counting the number of studies showing a positive, negative, or no effect. A search of the articles in the electronic databases of PubMed, Scopus, and Google Scholar was conducted. The effectiveness of RSE was assessed by vote counting, tallying the number of studies showing positive, neutral, or negative impacts on teenage driving behaviour aged 13-19 years. A total of seventeen studies were selected for inclusion using predefined criteria. Results: Upon conducting a systematic review, 17 key studies were identified for inclusion, reflecting diverse methodologies and focus areas. Across the research, it is evident that teenagers benefit significantly from receiving both theoretical knowledge and practical training. This comprehensive approach enhances their confidence and skills in adhering to traffic safety laws. Moreover, the involvement of parents and communities emerges as a vital factor for the success of educational initiatives. Conclusion: The study emphasizes the paramount importance of prioritizing long-term behavioural change and sustainability in road safety initiatives, particularly focusing on teenagers. It advocates for a comprehensive approach involving community and parental engagement alongside educational programs. The findings emphasize the necessity for policymakers in Southeast Asia to allocate funding towards culturally sensitive and standardized RSE programs, integrating practical training and long-term reinforcement strategies.

Background: Community-based HPV genotype data remain limited in southern Vietnam, where screening programmes must interpret genotype-specific risk in a population with low documented HPV vaccination. We described HPV prevalence, IARC Group 1 carcinogenic genotype distribution, infection multiplicity, and woman-level detection of HPV16/18 and of at least one genotype included in the nonavalent vaccine. Methods: From January to June 2026, we conducted a community-based cross-sectional study among 1,193 enrolled ever-married women aged 25–65 years in Ca Mau Province, Vietnam; the response-rate denominator was 1,565 women, yielding a response rate of 76.2%. A three-stage sampling design with random selection procedures was used. Because stage-specific selection probabilities were unavailable, prevalence estimates are reported as unweighted descriptive proportions. Cervical specimens were tested by real-time PCR for 23 HPV genotypes, and cervical cytology was performed concurrently. Crude proportions and Wilson 95% confidence intervals (CIs) calculated under a simple-random-sampling assumption are reported; no inferential comparisons were performed. Results: Crude, unweighted HPV prevalence was 7.1% (85/1,193; 95% CI 5.8–8.7); all 85 had a retrievable genotype result. Overall, 78 (91.8%) carried at least one manufacturer-designated high-risk genotype and 66 (77.6%) carried an IARC Group 1 carcinogenic genotype. HPV52 (20/85, 23.5%) and HPV58 (14/85, 16.5%) were the most frequently detected genotypes, followed by HPV16, HPV51 and HPV59 (each 10/85, 11.8%) and HPV18 (4/85, 4.7%); genotype frequencies were not compared statistically. Multiple genotypes were detected in 25/85 HPV-positive women (29.4%). Among women with an IARC Group 1 genotype, 52/66 (78.8%) had neither HPV16 nor HPV18. At least one nonavalent-vaccine genotype was detected in 50/85 HPV-positive women (58.8%). Conclusions: Overall HPV prevalence was low, HPV52 and HPV58 were the most frequently detected genotypes, and nearly four in five women with an IARC Group 1 carcinogenic genotype carried neither HPV16 nor HPV18. Because stage-specific selection probabilities were unavailable, these are unweighted descriptive estimates for the study sample rather than design-based estimates for Ca Mau Province. They describe the baseline genotype distribution in a population with low documented HPV vaccination. Genotype frequency should not be translated into local triage policy without longitudinal evidence linking individual types to histologically confirmed precancer and cancer.

Sarcopenia remains underdiagnosed in Vietnam due to the absence of simple, reliable screening instruments tailored to primary‐care settings, so we developed ViSarco to facilitate early identification of sarcopenia among community‐dwelling older adults; using a six‐phase exploratory mixed‐methods design, we generated candidate items through a comprehensive literature review and in‑depth interviews with 37 frontline healthcare providers, then conducted a cross‑sectional study of 416 adults aged ≥60 years applying AWGS 2019 criteria and logistic regression to assign scores of 2 for body‐mass index, 1 for arm circumference and 1 for calf circumference; we validated ViSarco in an independent cohort of 806 older adults and benchmarked its performance against six established international tools, finding that at a cut‑off score ≥2 it achieved 77.2% sensitivity, 76.6% specificity and an AUC of 0.77 in the derivation sample and maintained 78% overall accuracy with an AUC of 0.83 on external validation, outperforming all comparators; these results demonstrate that ViSarco is a brief, feasible and high‐performing screening tool well suited to resource‐limited primary‐care environments, offering robust diagnostic capability to support timely case finding and intervention for sarcopenia in older Vietnamese populations.
