Abstract
OBJECTIVE: This study aims to categorise health behaviours in patients with lower limb deep vein thrombosis and explore the factors that influence these behaviours. DESIGN: A cross-sectional study. SETTING: This study was conducted in four tertiary general hospitals in Urumqi, China. PARTICIPANTS: This study included a total of 544 participants. PRIMARY AND SECONDARY OUTCOME MEASURES: Self-rated abilities for health practices, health behaviour motivation, social support and health behaviour were the primary outcome measures. RESULTS: Model 3 demonstrated superior fit across indices, supported by an Entropy value of 0.806 and a significant bootstrap likelihood ratio test (p<0.001). The generalised linear mixed model identified self-rated abilities for health practices (p<0.05), health behaviour motivation and social support (both p<0.001) as factors associated with health behaviour latent profile subgroups among patients with lower limb deep vein thrombosis following hip or knee arthroplasty. CONCLUSION: Three latent health behaviour subgroups, namely low, moderate and good, were identified among patients with lower limb deep vein thrombosis following hip or knee arthroplasty. Self-rated abilities for health practices, health behaviour motivation and social support were associated with these subgroups. These findings may provide preliminary insights for developing targeted interventions to support health behaviour improvement in this patient population.
