Positive and negative psychosocial factors related to healthy and unhealthy weight control among nursing students.

ABSTRACT

BACKGROUND: Although nursing students are educated on the importance of exercising regularly and maintaining a well-balanced diet, many do not practice healthy weight management behaviors, and some even use unhealthy weight loss methods. Yet, little research has examined both positive and negative psychosocial variables related to weight control among nursing students. PURPOSE: The present study aimed to identify the most salient psychosocial variables related to healthy and unhealthy weight control among nursing students. METHOD: Using survey data from 241 nursing students, structural equation modeling was conducted to examine the relative contributions of eight interrelated psychosocial variables, including constructs from a strengths perspective (health-specific hope, health self-efficacy, social support, and body satisfaction) and from a deficit perspective (depression, anxiety, weight perception, and barriers to physical activity). RESULTS: Results showed that the degree to which individuals perceive themselves to be overweight was related to both healthy and unhealthy weight control. Aside from weight perception, health self-efficacy produced the strongest association with healthy weight control, and anxiety produced the strongest association with unhealthy weight control. The structural model explained 23 % of the variance in healthy weight control and 29 % of the variance in unhealthy weight control. CONCLUSIONS: These findings emphasize the need for tailored, integrated weight management interventions for nursing students that equip them with effective anxiety management skills and build self-efficacy.
