BACKGROUND: Osteoporosis is a common disease in women over age 45 years.Calcium intake is among the factors that help prevent osteoporosis. Identifying the social‑cognitivedeterminants of calcium intake can have a major role in the development of osteoporosis preventionprograms.MATERIALS AND METHODS: This cross‑sectional study was conducted on 400 womenaged <50 years from 10 health centers by cluster sampling in Isfahan in 2016. A hypotheticalsocial‑cognitive model was assessed using path analysis, and the fit indices and explanatory powerof the model were assessed. The constructs, including self‑efficacy, outcome expectations, socialsupport, and self‑regulation, were taken as the explanatory variables and calcium intake as thecriterion variable.RESULTS: The mean age of the participating women was 34.07 years (standard deviation = 7.99)(range = 19–50), and their mean calcium intake was reported as 909.94 (12. 6) mg/day. Theconceptual model was able to explain 73% of the variance in calcium intake and had good fit indices.Self‑regulation was identified as the strongest predictor of calcium intake, and outcome expectationwas eliminated from the model since it was the weakest explanatory factor of calcium intake.CONCLUSIONS: The theoretical model of this study is recommended as a suitable framework forthe development of targeted osteoporosis prevention interventions.
