    OBJECTIVE: This study aims to examine the behavioural intention of students to make voluntary blood donations. Moreover, it uses a theory of planned behaviour as its guiding principle and does so within the context of Malaysia, a developing nation.

    METHODS: Data were collected via a self-administered questionnaire from a sample of 500 students at a public higher learning institution in Malaysia. Structural equation modelling approach (SEM) was performed to assess the strength of the hypothesized relationships of the proposed model simultaneously via the two-stage model-building process.

    RESULTS: The SEM approach revealed that knowledge was the most influential predictor of students' intention to make a voluntary blood donation. With the knowledge that the more blood they donate, the more lives will be saved, the inclination to donate blood is intensifying among students. Moreover, all of the TPB constructs applied were also seen to significantly influence students' response to voluntary blood donation.

    CONCLUSIONS: The nexus of attitude, subjective norm, perceived behavioural control, and knowledge about students' intention to perform voluntary blood donation are evidenced in a developing nation. The implications of the study and directions for future research are provided.

    Adverse donor reactions (ADR) are common to occur during the blood donation process. The most common is vasovagal reactions (VVR) and it cause negative impact in the donor return rate. The aim of this study is to determine the prevalence of VVR among blood donors and to study its associated factors, at Hospital University Sains Malaysia (USM). This retrospective case-control study was conducted from June 2018, until June 2021. Data was extracted from the blood bank database system and from donor adverse reaction form. Donors who developed adverse donor reactions were chosen and without VVR were chosen at random as controls. A total of 159 donors, out of 35 134 donors were reported to have VVR which resulted in an overall prevalence of 0.45 %. Dizziness or mild VVR were the most frequently observed adverse reactions, accounting for approximately 87/159 (54.7 %) of all adverse reactions. Multiple logistic regression (MLR) analysis showed VVR were significantly associated with age, female gender, first-time donor, and 450 ml volume of blood collected. The prevalence of vasovagal reactions among blood donors in this study was low which was similar to a few previous studies. Although it was low, still it is very important to reduce risks to a minimum so that the donor return rate could be maintained. The information regarding its associated factors can be used to identify high-risk donors to prevent the incidence in the future.
