Chon, Jeon, and Kim: Bone Mineral Density and Factors influencing Bone Mineral Density in College Women

Abstract

Purpose

The purpose of this study was to identify the levels of bone mineral density (BMD) and to explain the factors influencing BMD among female college students in Korea.

Methods

A cross-sectional study was conducted with 144 college women. Lifestyle factors were determined by self-report questionnaire. Body composition was measured by body composition analyzer and bone mineral density was measured by ultrasound bone densitometry. Data were analyzed using SPSS for windows, version 19.0.

Results

The mean BMD at calcaneus site was 0.56 g/cm2 (mean T-score=-0.22). The incidence of osteopenia was 21.5%. Factors predicting BMD were menarche age (r=-.22, p=.009) and height (r=-.18, p=.030) with 7% of explained variance.

Conclusion

These results suggest that health care professionals need to provide young women with program that is intended to affect their intention toward osteoporosis preventive behavior change.

Summary Statement

▪ What is already known about this topic?
Life style and body composition have been implicated as factors related to bone mineral density (BMD), but the results to date have not been consistent.
▪ What this paper adds?
Menarche age and height negatively predicted bone mineral density among college women.
In spite of low bone mineral density, those who did not have any intention to improve their osteoporosis preventive behaviors have displayed low bone density and this group is most likely to be considered as a group that has a high risk towards osteoporosis.
▪ Implications for practice, education and policy
Health care professionals need to provide young women with programs that are intended to affect their intention toward osteoporosis preventive behavior.
