Stroke is one of the top causes of disability in Malaysia, yet caregivers have limited access to structured, culturally tailored education to support poststroke care.

To develop and validate the CaknaStrok Education Package (CEP), a blended learning intervention comprising a printed guidebook and a trilingual mobile health application for informal stroke caregivers in Malaysia.

Methodological study involving the development and validation of a caregiver education programme guided by the Analyse, Design, Develop, Implement, Evaluate (ADDIE) instructional design framework.

Development and validation were conducted in Malaysia between January 2022 and December 2023. Both experts and caregivers were recruited from two tertiary hospitals on the East Coast of Malaysia, with caregivers identified from inpatient wards and outpatient clinics at these hospitals.

Content validation involved 10 multidisciplinary experts. Face validation involved 14 informal stroke caregivers who met eligibility criteria, and all completed the study.

CEP was developed based on prior needs assessment and expert input. Content validation was undertaken using the Content Validity Index (CVI) and face validation using the Face Validity Index (FVI), both assessed on a four-point Likert scale. Qualitative feedback was also obtained from the participants.

CEP consists of six modules delivered via a printed guidebook and a trilingual app with videos, assessment tools and local resources. Experts rated the content highly valid (Scale-level (S)-CVI/the average method (Ave): 0.97–0.99 across domains). Caregivers reported strong acceptability (S-FVI/Ave: 0.95–0.99). Qualitative feedback from experts and caregivers informed refinements to content clarity, usability and presentation, including improved navigation, consistent language use and enhanced visual design. Suggestions requiring substantial structural changes were documented for future iterations.

The CEP shows strong content and face validity as a blended caregiver education tool. By combining printed and digital formats, CEP addresses cultural and access challenges and provides a scalable model for stroke caregiver education in Malaysia. Further pilot or feasibility studies are warranted to evaluate usability, engagement and implementation in real-world settings prior to effectiveness evaluation.

To determine the prevalence and its associated factors of dual tobacco use among Malaysian adolescents in developing effective public health strategies.

Cross-sectional study.

This study analysed data from the National Health and Morbidity Survey (NHMS) 2022: Adolescent Health Survey (AHS), a nationwide cross-sectional survey conducted among secondary school students across Malaysia.

This cross-sectional study used data from the NHMS 2022: AHS, which included a representative national sample of Malaysian adolescents between the ages of 13 and 17. Using a two-stage stratified sampling approach, this study included participation from 33 523 adolescents from 240 schools nationwide.

The primary outcome was the prevalence of dual tobacco use among Malaysian school-going adolescents aged 13–17, defined as self-reported concurrent use of conventional cigarettes and e-cigarettes in the past 30 days. Secondary outcomes included the factors associated with dual tobacco use, such as sociodemographic characteristics, dual tobacco use behaviour, marital status of parents, tobacco use of parent or guardian, supervision, connectedness, bonding and respect for privacy of parent or guardian, along with peer support and truancy. A complex sample analysis was performed using SPSS V.27.0, maintaining a 95% CI and multiple logistic regression was applied.

Out of 33 380 Malaysian adolescents surveyed, 1728 (5.5%; 95% CI: 4.88% to 6.28%) reported dual tobacco use. The prevalence was significantly higher among males (9.7%; 95% CI: 8.54% to 10.98%) compared with females (1.4%; 95% CI: 1.15% to 1.70%) and highest among 17 years (8.6%; 95% CI: 7.05% to 10.41%), with a decreasing trend in younger age groups. Predominant vapers constituted the largest proportion (9.9%, 95% CI: 8.66% to 10.13%) among adolescents who reported dual tobacco use, followed by predominant smokers (6.2%, 95% CI: 5.53% to 7.06%), dual daily users (4.5%, 95% CI: 3.18% to 5.64%) and non-daily dual users (3.9%, 95% CI: 2.79% to 4.39%). Dual tobacco use was more prevalent among adolescents whose parents or guardians used tobacco (8.1%; 95% CI: 7.10% to 9.20%). Multiple logistic regression analysis suggested that significant predictors of dual tobacco use included older age (adjusted OR (AOR) for 17 years: 2.92; 95% CI: 2.19 to 3.89), male sex (AOR: 8.53; 95% CI: 6.78 to 10.74), ‘others’ ethnicity (AOR: 1.82; 95% CI: 1.40 to 2.35), predominant vapers (AOR 2.65, 95% CI: 1.96 to 2.72), separated or widowed parental status (AOR: 1.69; 95% CI: 1.42 to 2.02), parental or guardian tobacco use (AOR: 2.47; 95% CI: 2.08 to 2.94), lack of bonding (AOR: 1.79; 95% CI: 1.49 to 2.14), lack of privacy respect (AOR: 1.53; 95% CI: 1.29 to 1.81), lack of peer support (AOR: 1.65; 95% CI: 1.39 to 1.96) and truancy (AOR: 1.81; 95% CI: 1.55 to 2.10).

This study highlights a concerning prevalence of dual tobacco use (5.5%) among Malaysian adolescents, which is notably higher than the current prevalence of exclusive cigarette smoking (6.2%) and closely approaches that of e-cigarette use (14.9%). Compared with previous national surveys and international benchmarks, the prevalence of dual use among Malaysian youth appears to be rising and represents a significant public health concern. These findings underscore the urgent need for targeted prevention and control strategies addressing both conventional and emerging tobacco products in this population.
