Abstract:
The purpose of this longitudinal repeated measures experimental study was to determine the effects of bone health testing using dual energy X-ray absorptiometry (DXA) on outcomes of intentions toward and actual engagement in bone health behaviors (calcium intake, vitamin D intake, physical activity) among perimenopausal women. The Perimenopausal Bone Health Behaviors Model was developed based on the Theory of Planned Behavior and guided this study to determine how perimenopausal women respond to DXA and bone health information compared to bone health information only.One hundred fifty community-based perimenopausal women (ages 35-55) were randomly assigned to an intervention group (n=75 DXA and bone health information) or to a comparison group (n=75 bone health information). Baseline demographic data were collected. The Prevention Intentions Questionnaire and Behaviors Questionnaire were administered at baseline, at two weeks, and at two months after both groups received assigned interventions.Results showed 32% (n = 24) of intervention group women had low bone density. The intervention of DXA and bone health information showed near-significance (p = .068) over the intervention of bone health information alone in affecting women's intentions, and showed near-significance in affecting calcium intake (p = .052). Lower bone density test scores were related to higher intentions (r(74) = -.23, p = .046) at two weeks after DXA and bone health information, and were related to improved vitamin D intake (r(73) = -.25, p = .03) at two months after DXA and bone health information. At study end, Attitudes contributed 27.0% of the variance in Intentions among women who received DXA and bone health information; Attitudes, Subjective Norms, and Perceived Behavioral Control contributed 62.0% of the variance in Intentions among women who received bone health information only.Nursing interventions focusing on perimenopausal women should include providing bone health information to all perimenopausal women. Interventions targeting attitudes toward bone health behaviors may motivate some perimenopausal women to participate in behaviors that contribute to decreased risk of osteoporosis. Early detection and intervention in perimenopausal bone loss may reduce osteoporosis morbidity and may impact women's quality of life, reduce financial consequences to individuals, families, communities, and the nation.
