Purpose:
This study described female college students' knowledge, self-efficacy and health behaviors related to bone health.
Methods:
A descriptive cross-sectional survey design was used. A total of 214 students were conveniently recruited from a school of nursing in Korea. Participants (mean age=21.2, SD=1.9 years) bone mineral density (BMD) was measured using dual energy x-ray absorptionmetry. Participants also completed a questionnaire consisting of knowledge test, self-efficacy scale and health behaviors related to bone health. Data were analyzed using SPSS/WIN 17.0 program.
Results:
The mean BMD at left femoral neck site was 0.86 g/cm2 and 6.1~12.6%. Results showed that participants were below the expected range of BMD. Level of knowledge (correct rate=54%) and self-efficacy were moderate (mean 54.8 out of 84). More than 84% of subjects drank alcohol more than once a month and 58.4% did participate in regular exercise. Only 7.9% participants took calcium and vitamin-D rich foods every day. There were significant positive correlations between knowledge and self-efficacy (r=.17), health behaviors (r=.14) and self-efficacy and health behaviors (r=.28, all p<.05).
Conclusion:
These results suggest that health care professionals need to provide effective interventions for young women in order to enhance knowledge, self-efficacy and health behaviors related to bone health.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
