BACKGROUND: To investigate the relationship between body composition and bone mineral density (BMD) in preand post-menopausal women in Korea. METHODS: The data of 4,334 pre- and post-menopausal women older than 20 years from the Korea National Health and Nutrition Examination Survey conducted in 2008-2009 were assessed. BMD and body composition were measured by dual-energy X-ray absorptiometry. All analyses except stepwise multiple linear regression analysis were performed using the KNHANES sample weights to account for the complex survey design. RESULTS: After adjusting for confounding variables, lean mass and fat mass were positively correlated with BMD at both L1-4 spine and femur neck in both pre- and post-menopausal women (P<0.001). For the pre-menopausal women, lean mass was the most important determinant of BMD at both sites (R2=0.156 for L1-4 spine BMD, R2=0.168 for femur neck BMD), and the impact of fat mass were minimal. For the post-menopausal women, fat mass had a greater influence on the BMD at L1-4 spine than lean mass (R2=0.016 vs. R2=0.077), but lean mass had a greater impact than fat mass on the BMD at the femur neck (R2=0.077 vs. R2=0.007). After adjusting for confounding variables, post-menopausal osteoporosis increased as both lean mass and fat mass decreased (P(trend)<0.001). CONCLUSIONS: In Korean pre- and post-menopausal women, both lean mass and fat mass had positive correlations with the BMD at both sites and decreased the risk of osteoporosis. Lean mass had a greater influence on premenopausal BMD at both sites and postmenopausal BMD at the femur neck, whereas fat mass had greater influence on post-menopausal BMD at L1-4 spine.

Influenza is a disease known to continue to afflict a large number f people and cause many deaths throughout the world. Influenza A and B are the two types of influenza that cause epidemic human disease. The influenza illness is characterized by the abrupt onset of fever, myalgia, headache, and sore throat. Amantadine and rimantadine have been used to treatment and prophylaxis of influenza, but these agents can only reduce symptomatic illness due to influenza A virus and are ineffective against influenza B virus. Inhibitors of influenza neuraminidase constitute a new class of anti-influenza agents that reduce replication of influenza A and influenza B. Vaccination against influenza virus is the primary strategy to reduce the morbidity and mortality associated with influenza.
