Glucocorticoids and the risk of osteoporosis

BACKGROUND

Glucocorticoid-induced osteoporosis (GIO) refers to a clinical condition in which a class of corticosteroids increases the susceptibility of bones to fracture. Numerous recent studies have improved our understanding of the underlying biology of this condition, whereas data from randomized controlled trials have provided clinicians with more options for prevention of GIO.

OBJECTIVE

To review the pathophysiology and epidemiology of GIO, as well as current pharmacologic treatment and prevention modalities available. To review the state of healthcare provider concordance with GIO prevention guidelines.

METHODS

Representative examples of various cellular and molecular processes underlying GIO were included, with an emphasis towards more recent discoveries. The data used to describe the epidemiology of GIO were derived from both randomized controlled studies and observational studies, framed through a discussion of known osteoporosis risk factors.

RESULTS/CONCLUSION

Progress has been made in clarifying the pathophysiologic mechanisms that result in GIO. Although the options for preventions and treatment of GIO continue to expand, provider compliance with preventive measures remains suboptimal.

Effects of an osteoporosis educational programme for men

AIM

This paper reports an evaluation of the effects on knowledge, health beliefs and preventive behaviours of an osteoporosis educational programme for men.

BACKGROUND

Osteoporosis is an increasing global health concern, and educational programmes have been identified as a crucial strategy in its prevention. However, the effectiveness of osteoporosis educational programmes has mainly been evaluated in women.

METHODS

A randomized controlled trial was carried out to identify the effects of an osteoporosis educational programme for men. The study was conducted between September 2004 to February 2005, and 128 Hong Kong Chinese men were randomly assigned to an intervention or control group, with 64 in each group. The intervention group attended an osteoporosis educational programme. All participants completed pre- and post-test self-administered questionnaires: Osteoporosis Knowledge Test, Osteoporosis Health Belief Scale and Osteoporosis Self-Efficacy Scale.

RESULTS

The intervention group showed a statistically significant increase in both knowledge (P < 0.0005) and health beliefs (P = 0.007) about osteoporosis and preventive behaviours in comparison with the control group. However, the difference in self-efficacy between the two groups was not statistically significant (P = 0.154).

CONCLUSIONS

An osteoporosis educational programme can increase men's knowledge levels and change their health beliefs about osteoporosis and preventive behaviours. This approach should be more widely used in nursing practice to promoting the adoption of osteoporosis prevention behaviours in men.
