Background: Eighty percent of the 10 million people with osteoporosis and the additional 34 million with osteopenia are women. Few are tested for bone density before menopause, and are unaware of their bone health despite the rapid perimenopausal decline. This study will provide beginning data on perimenopausal women's predicted and actual behavioral response to bone health testing. Purpose: To determine effects of bone health testing using dual energy X-ray absorptiometry (DXA) on outcomes of intention and actual osteoporosis preventive behaviors (OPB) among perimenopausal women. Aims: 1. To determine effects of DXA intervention on OPB intention and actual behaviors. 2. To determine differences in OPB intention and actual behaviors among women with abnormal DXA and normal DXA results. 3. To explore the influence of OPB attitudes, subjective norms, and perceived behavioral control on OPB intentions and actual behaviors. Theoretical Framework: The Perimenopausal Osteoporosis Preventive Behavior Model (POPBM) is based on Ajzen's Theory of Planned Behavior (TPB). TPB constructs are Intention and Actual OPB (calcium/vitamin D intake and exercise) with independent antecedent constructs of Attitude, perception of social pressure (Subjective Norm), and perceived ease or difficulty of performing OPB (Perceived Behavioral Control). Methods/Proposed Study Design: The POPBM is untested. A longitudinal repeated measures experimental design will use random assignment to consign 80 qualified women to a comparison group (n=40, usual and customary Targeted Osteoporosis Education [TOE]) or to a treatment group (n=40, TOE and DXA). Baseline demographic data will be collected; outcomes of actual OPB and the Perimenopausal Bone Health Motivation (PBHM) Scale using TPB constructs will be measured at baseline, after target group DXA application, and at two months after baseline. Statistical analysis of covariance will analyze Aim 1, analysis of variance for Aim 2, and multiple regression for Aim 3. Implications for Nursing: Studying this osteoporosis-vulnerable population is important. Early identification and focus on promoting bone health may reduce overall osteoporosis morbidity thus impacting women's quality of life, and reducing significant financial consequences.
