Osteoporosis Prevention in College Women: Application of the Expanded Health Belief Model

Lorraine Silver Wallace, PhD  

Objective: To examine personal characteristics and expanded health belief model (EHBM) constructs associated with the practice of osteoporosis-protective behaviors among a random sample of nontraditional college women. Methods: A valid and reliable written mail questionnaire assessing osteoporosis knowledge, EHBM constructs, weight-bearing exercise (EX), and dietary calcium intake (CA) was completed by 273 women. Results: A high proportion of women did not meet current guidelines for EX (50.7%) or CA (67.8%). Exercise self-efficacy and barriers to exercise were the best predictors of overall EX and CA behaviors. Conclusion: The EHBM was useful in predicting EX and CA.
