Abstract: Aims and objectives To examine the roles of two modifiable factors—health‐promoting behaviours and perceived stress—in predicting aneurysmal rupture. Background Unruptured intracranial aneurysm detection produces significant stress and anxiety in patients because of the risk of rupture. Compared to nonmodifiable risk factors for rupture such as age, gender and aneurysm size/location, less attention has been given to modifiable risk factors. Two modifiable factors, health‐promoting behaviours and perceived stress, have hardly been examined as potential predictors of rupture. Design This study used a cross‐sectional design. Methods We assessed 155 patients with intracranial aneurysms—that is, subarachnoid haemorrhage (n = 77) or unruptured intracranial aneurysm (n = 78)—to examine (i) baseline characteristics (patient and aneurysmal factors), (ii) health‐related factors (lifestyle habits and health‐promoting behaviour) and (iii) perceived stress levels (psychological stress and physical stress). Patient records provided medical histories and aneurysmal factors; other data were collected using a structured questionnaire addressing lifestyle habits, the Health‐Promoting Lifestyle Profile‐II to measure health‐promoting behaviour and the Perceived Stress Questionnaire to measure perceived‐psychological stress and perceived‐physical stress levels. Results Bivariate analysis indicated that aneurysm rupture risk was associated with female gender, aneurysm size/location, defecation frequency, hyperlipidaemia, sedentary time, low Health‐Promoting Lifestyle Profile‐II mean scores and high perceived‐psychological stress scores. After adjusting for known risk factors, the mean Health‐Promoting Lifestyle Profile‐II and perceived‐psychological stress scores remained robust predictors of rupture. Furthermore, known risk factors combined with these scores had greater predictive power than known risk factors alone. Conclusion Health‐promoting behaviour and psychological stress are promising modifiable factors for reducing risk of aneurysmal rupture. Relevance to clinical practice Our findings may stimulate greater understanding of mechanisms underlying aneurysmal rupture and suggest practical strategies for nurses to employ in optimising conservative management of rupture risk by teaching patients how to modify their risk. Both health‐promoting behaviour and perceived stress should be addressed when designing preventive nursing interventions for patients with unruptured intracranial aneurysm.
