| Research Abstract |
We have performed a prospective 2-year cohort study for 208 Japanese institutionalized elderly to study the risk factors for all-cause mortality and upper tract respiratory infection with emphasis on serum vitamin D level and BMI. Vitamin D deficiency(25OHD<10ng/mL) was associated with increased infection, although not statistically significant by Kaplan. Meier plots(log-rank test ; p=0.20). Serum vitamin D level was not significantly associated with all-cause mortality or upper respiratory tract infection by Cox regression analyses. BMI was a significant predictor for all-cause mortality(HR, 0.86, 95% CI ; 0.76-0.97) by Cox regression analyses. BMI. 20.3 kg/m2 was associated with significantly increased risk of mortality.
