Clinical staff can promote patients’ engagement in health-promoting behaviors to prevent/treat obesity. However, some clinical staff are overweight/obese and may not model health behaviors for their patients. This cross-sectional survey study tested the hypotheses that clinical staff’s level of (1) motivators and (2) barriers to engaging in health-promoting behaviors would be significantly associated with their body mass index (BMI). Barriers were significantly correlated and motivators were not correlated with caregivers’ BMI. Implications for nurses in professional development are discussed.
