Purpose: (1) Difference of homocysteine in female elderly with different body shapes. (2) Correlation between functional physical fitness and homocysteine. (3) Correlation between physiological values. Methods: The study objects comprised 32 female elderly aged 65 years old, whose body mass index (BMI) was applied to categorize all respondents into 11 respondents in normal weight group (18.5≦BMI＜24), 12 respondents in overweight group (24≦BMI＜27), and 9 respondents in obesity group (BMI≧27). All respondents underwent 8 hours of fasting overnight for blood drawing to analyze the concentration of homocysteine, folic acid, and Vitamin B12 in blood. The respondents also took measurement of physiological values (including BMI, body fat rate, waistline, and waist-hip ratio). Tests of functional physical fitness include: two-minute step test (aerobic endurance test), back scratch test (upper limb flexibility), seated forward bend (lower limb flexibility), eight-foot up-and-go (dynamic balance), 30-second single-leg stand (static balance), arm curls (upper limb muscle strength), and 30-second chair-to-stand (lower limb muscle strength). The results yielded then underwent one-way ANOVA, independent sample t-test, Pearson’s correlation coefficient, and multiple regression analysis. Results: (1) There is no significant difference (p＞.05) among homocysteine, folic acid and Vitamin B12 between the normal weight group, overweight group and obesity group. (2) For correlation between homocysteine and functional physical fitness, only seated forward bend (lower limb flexibility) reached significance (p＜.05). (3) Multiple regression analysis was conducted using BMI, waistline and body fat rate as independent variables while homocysteine was used as dependent variable. The results showed that only the body fat rate reached significance (p＜.05) and R2＝.34. Conclusion: Different body shapes (using BMI as indicator) do not have significant difference in homocysteine and body fat rate is the forecast indicator for the concentration of homocysteine in blood, which explains 34% of variance.
