Outcome Measures

Primary Outcomes (5)

  • Table 1 Study Specific Characteristic Part One

    The percentage of female, race, hypertenion history, diabetes history, and hyperlipemia history was calculated.

    at baseline

  • Table 1 Study Specific Characteristic of Age

    the mean and standard deviation of age was calculated in four groups

    at baseline

  • Table 1 Study Specific Characteristic of Body Mass Index (BMI)

    the mean and standard deviation of BMI in four groups was calculated

    at baseline

  • Table 1 Study Specific Characteristic of Blood Pressure (BP)

    systolic BP and diastolic BP in four groups was measure twice between 15minutes

    at baseline

  • Table 1 Study Specific Characteristic of Serum Carotenoids

    serum major carotenoids, including lutein, zeaxanthin, beta-carotene, and lycopene concentration were measured by hyper-pressure liquid chromatography (HPLC)

    at baseline

Secondary Outcomes (3)

  • Changes of Right Common Carotid Arterial Stiffness Parameter β(R-β) at Baseline and After 12 Months

    at baseline and after 12 months

  • Dietary Intake of Energy During the Study Periods

    at baseline and 12 months

  • Dietary Intake of Vitamin C,Vitamin E, Lutein Plus Zeaxanthin and Lycopene During the Study Periods

    at baseline and 12 months
