Osteoporosis is serious public health issue and can be a preventable disease. Objective: The purpose of this study was to determine osteoporosis knowledge, health believes and calcium intake in a sample of Saudi adults. Design & Subjects: A descriptive, web-based survey included 572 Saudi adults (287 female, 285 male) aged between 20 and 55 years living in AL-Hasa, Saudi Arabia were recruited by email. Methods: The Osteoporosis Knowledge Test (OKT), Osteoporosis Health Belief Scale (OHBS), and food frequency questionnaire were utilized. Results: There was a lacking in osteoporosis knowledge, with a mean total score for female (9.4+2.7) and male (8.7+2.6) out of a possible 20 correct responses. Mean scores for osteoporosis knowledge were statistically different between groups (P =0.011). Overall, subjects perceived themselves as moderate susceptible to develop osteoporosis and consider osteoporosis to be low serious disease with significant different between groups (P =0.02, 0.008; respectively). Subjects had high perceived benefits of calcium intake, perceived benefits of exercise, and perceived health motivation without significant different between groups. Female had significant (P =0.009) more perceived barriers to exercise (15.7+4.5) comparable to male (16.9+4.1). In addition subjects had moderate perceived barriers to eating calcium rich foods. Perceived susceptibly (R=0.161, P<0.05), perceived severity (R=0.192, P<0.01), and perceived barriers to exercise (R=-0.184,P<0.05) were significantly correlated to calcium intake among female only. Conclusion: These finding suggest that osteoporosis prevention intervention need to increase knowledge, overcome exercise and calcium intake barriers, and motivating them to healthy behaviors.
