Tailored interventions to enhance osteoporosis prevention in women

Abstract

Purpose: The purpose of this pilot study was to determine if tailored nursing interventions based on personal knowledge of bone mineral density from a dual-energy x-ray absorptiometry cause increases in knowledge of osteoporosis, health beliefs, or osteoporosis-prevention behaviors in postmenopausal women 50-65 years of age, 6 months after the intervention.

Method: The design for this pilot study was a two group quasi-experimental design. The treatment group received a tailored intervention; the control group did not. Outcome data were gathered at 6 months after dual-energy x-ray absorptiometry. The tailored intervention was designed and given to each woman via telephone using her dual-energy x-ray absorptiometry results and osteoporosis questionnaire data that addressed her knowledge of osteoporosis and osteoporosis-prevention behaviors of calcium intake, exercise, smoking, and alcohol use. A written mailed copy of the intervention followed the telephone interview. Six months after the intervention, the women were mailed another osteoporosis questionnaire to determine if the tailored intervention made a difference in the outcome variables.

Sample: A total 124 women between the ages of 50 and 65 (101 control, 23 treatment) comprised the sample.

Results: There was no difference in knowledge between groups. On the average, there were significantly more perceived barriers to calcium in the tailored group (mean = 13.48) than in the nontailored group (mean = 11.55) (t = 2.147; df = 122; p = .034). There were significantly more perceived barriers to exercise in the tailored group (mean = 14.39) than in the nontailored group (mean = 12.21) (t = .144; df = 122; p = .034). Daily calcium intake increased in both the tailored and the nontailored groups. The tailored intervention increased women's daily calcium intake from 614.28 to 1039.10 mg (t = -2.896; df = 22; p = .008). The nontailored group daily calcium intake increased from 587.91 to 916.30 mg (t = -3.541; df = 100; p = .001); there was no significant difference between the groups. Weight-bearing exercise behaviors decreased from 96.04 minutes to 59.2 minutes in the tailored group but increased slightly in the nontailored group from 81.47 to 87.26 minutes of exercise.

Conclusion: Tailored interventions increased women's perceived barriers to calcium and exercise. Both groups increased calcium intake. The mixed findings of increased perception of barriers to calcium and exercise and decreased exercise behaviors indicate the need for further study. This important intervention has implications for orthopaedic nurses and healthcare professionals involved in health promotion and prevention of osteoporosis.
