Using a representative dataset from the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2011, we analyzed anthropometric and dual-energy X-ray absorptiometry (DXA)-determined body composition findings for 493 cancer survivors (mean age a61. 1 ± 12. 6 years; 35. 7% male). A much higher proportion of men (30. 1%) than women (0. 6%) met the criteria of sarcopenia. SUBJECTS
with a history of lung cancer, genitourinary cancer, or gastric cancer were prone to develop sarcopenia (31.6%, 26. 3%, and 21. 4%, respectively). Furthermore, sarcopenia was more prevalent among elderly (=65 years; P < 0. 001), those with a lower BMI level (<23 kg/m(2); P < 0. 001), heavy drinker (P = 0. 012), or smoker (P < 0. 001), and those with inadequate intakes of protein (P = 0. 017) and vitamin A (P = 0. 024). Multivariable logistic analyses revealed sarcopenia was significantly associated with male gender (odds ratio [OR], 68. 14; 95% CI, 15. 52-299. 13), a BMI of <23 kg/m(2) (OR 35. 93, 95% CI, 8. 24-156. 67), and inadequate protein intake (OR 3. 07, 95% CI, 1. 30-7. 22); these factors are significant predictors of sarcopenia in Korean cancer survivors.
