| Summary: | 碩士 === 國立臺北教育大學 === 體育學系碩士班 === 106 === Background：C-reactive protein (CRP) has been used as a new indicator for evaluating cardiovascular disease in recent years; C-reactive protein is a better predictor of cardiovascular disease than low-density lipoprotein-cholesterol (LDL-C) index. Purpose：(1) Differences in the relative risk index and risk level of cardiovascular disease among the five groups with different physical activity (classified by daily average steps).(2) The difference in the relative risk index and risk level of cardiovascular disease between the group of "Days of the Day" and "The Steps of the Days".(3) The amount of physical activity (average number of steps per day) is related to the relative risk index and risk level of cardiovascular. Method：In 32 female seniors in Daan District of Taipei City for the study, all subjects fasted overnight once each blood draw, the blood analysis C- reactive protein (CRP), total cholesterol (TC), HDL - cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), and measuring physiological values;The classification of physical activity levels uses a pedometer to track the average number of steps per day; Combine CRP and LDL-C to assess the overall cardiovascular risk level of each subject (classified as high, medium, and low risk), In addition, the CRP and TC:HDL-C ratios were combined to assess the overall cardiovascular relative risk index for each subject. The results were analyzed by ANOVA, Independent sample t-test, Pearson Correlation, and chi-square test. Results：I. There were no significant differences in cardiovascular relative risk index, risk grade, and C-reactive protein concentration among the five different physical activity populations (p>.05). II. "Thousand steps a day without" and "less than ten thousand steps a day in" the number ratio of 40.6% and 59.6%, respectively, relative risk index between the two groups in cardiovascular risk level was no significant difference (p> .05).Conclusion: I. Daan District Seniors female ratio has reached 10,000 steps a day in 40%. II. The relative risk of cardiovascular disease in females in Da'an District is 3.6 times higher than that of normal healthy people. III Suffering from high rates of risk (risk + high risk) accounted for 50%, recommended that these high-risk women or senior citizens can increase physical activity, lifestyle changes or further medical examination. IV. Different physical activity (in terms of daily average steps) cannot be used as a predictor of the relative risk index and risk level of cardiovascular disease.
