Structural model for XXXX preventing behavior in postmenopausal @entity1 .

@entity1 @entity170 @entity79 @entity2331 @entity460
BACKGROUND: @entity170 prevention behaviors (OPBs) can prevent and delay @entity79 ; dual-energy X-ray absorptiometry (DXA) scan can identify @entity170 and provide personal @entity170 risk information that may promote prevention behaviors. OBJECTIVES: This study was designed to estimate relationships between receiving personal knowledge of bone mineral density (gained through DXA scan), general knowledge of @entity170 , health beliefs, and the two OPBs of @entity460 intake and weight-bearing exercise in healthy postmenopausal @entity1 50 to 65 years. METHODS: In this longitudinal, randomized clinical trial (including covariates), receipt of personal DXA information was manipulated by random assignment to the experimental or control group. The remaining antecedent and outcome variable measures were collected by questionnaire at three time points (initial [T1; pre-DXA], 6 months [T2], 12 months [T3]) and by bone density assessment from 203 @entity1 over an 18-month period in 2001-2003. RESULTS: The experimental manipulation (DXA results) had a direct positive effect (beta = .23, p < .05) on @entity460 intake at T2, and indirectly at T3 through T2. @entity1 in the experimental group who were informed they had @entity2331 or @entity170 had a greater T1-T2 change in daily @entity460 intake than those with normal bone density (beta = .23, p < .05). However, providing DXA results did not relate to change in exercise. Health beliefs and general @entity170 knowledge predicted initial @entity460 and exercise levels; there was tentative evidence that susceptibility beliefs partially mediate between DXA results and change in @entity460 intake. DISCUSSION: Personal knowledge of DXA results was related significantly to increases in @entity460 intake in postmenopausal @entity1 , but not to exercise. Directions for further study are discussed.
