Child abuse is a global problem. Shaken baby syndrome (SBS) is a result of child abuse, with shaking being the most common form of maltreatment, causing mortality or severe brain damage in infants. A lack of awareness of SBS among current and future healthcare professionals can have serious consequences. To date, no studies have been conducted in Saudi Arabia to examine student nurses' awareness of SBS, so we sought to assess this issue in an academic institution in Riyadh, Saudi Arabia. For this questionnaire-based study, we employed a cross-sectional, descriptive design. The target population was nursing students from every year of study in the institution's five-year undergraduate nursing programme, who received an online questionnaire during the 2022-2023 academic year. The data were analysed using descriptive and inferential statistical analysis. Of the 293 respondents, 100.0% confirmed that they were not aware of SBS through their nursing curricula, and 62.1% reported not being made aware of SBS at all during their academic journey. The majority of participants were unaware of the negative consequences of shaking a baby. Most were not aware that shaking a baby vigorously can cause permanent blindness (73.4%), postural impairments (56.7%), sleep disorders (61.1%), or convulsions (60.1%). The results of our study revealed a statistically significant relationship between nursing students' awareness of SBS and both their year of study and marital status. Those at higher academic levels and those who were married were more aware of SBS. To improve nursing students' knowledge of SBS and help them to better inform the public of this syndrome, particularly parents, child maltreatment topics should be added to nursing curricula in Saudi Arabia, and their importance should be emphasised. This will help reduce the prevalence and burden of SBS nationally.
