Physical Activity for Campus Employees (PACE)
研究概览
详细说明
Cardiovascular disease (CVD) persists as the leading cause of mortality in the United States and accounts for 17 percent of the nation's overall health expenditures. Although the mortality rate of CVD has declined in recent years, the burden of disease remains high. Currently, 1 in 3 Americans has some form of CVD. Additionally, according to a recent policy statement published by the American Heart Association (AHA), 40% of the population is projected to have some form of CVD by 2030. Furthermore, the AHA has projected that the cost to treat CVD will triple by 2030. The prevalence and rising financial burden of CVD demonstrate the urgency for effective implementation of disease prevention strategies.
Evidence suggesting the majority of CVD is preventable through modifiable risk factor management continues to grow. Nonetheless, difficulty controlling modifiable risk factors remains an issue for many Americans. The magnitude of this challenge is supported by a study revealing that 78% of adults are candidates for at least one CVD prevention activity. Although national organizations have published a variety of disease prevention recommendations, widespread implementation of and adherence to preventative programs remain problematic. Consequently, a large proportion of the population is not receiving or participating in prevention strategies from which they may benefit. The full potential of reducing the nation's CVD burden cannot be achieved unless interventions are implemented on a larger scale, with reduced costs, and with increased initial and continued participation.
With approximately 130 million Americans currently employed, workplaces provide ideal environments for implementation of sizable, cost-effective CVD prevention programs. However, successful wellness programming remains a laborious, resource intensive challenge for employers. In 2004, a National Worksite Health Promotion Survey disclosed that less than 7% of U.S. employers offered worksite wellness programs. Furthermore, an estimated 25-30% of companies' annual medical costs are spent on employees with CVD risk factors.
In the proposed study, a worksite wellness program that includes health assessments, personal health reports, and pedometer-based tracking of physical activity will be offered to university employees. Participants will not be randomized to an intervention or control group. Rather, program components will be available to all enrolled participants, and each individual may choose whether to wear a pedometer, track their step counts, attend wellness sessions, and/or complete the health assessments. There is no prescribed intervention. Wellness sessions include educational information on lifestyle behaviors to promote cardiometabolic health.

措施说明 |
大体时间 |
---|---|---|
Daily Step Count (determined by pedometer)
大体时间:Baseline, week 4, and week 8
|
Daily step counts, as recorded by pedometers, will be self-reported by participants for 7 continuous days at 3 study time points: baseline, week 4, and week 8.
|
Baseline, week 4, and week 8

次要结果测量
结果测量 |
措施说明 |
大体时间 |
---|---|---|
Body weight
大体时间:Baseline and week 9
|
Body weight will be measured on a digital scale in the morning after an overnight fast.
Shoes, jewelry, sweaters, jackets, belts, and hats will be removed and pockets will be emptied before the measurement is made.
|
Baseline and week 9
|
Body Mass Index (BMI)
大体时间:Baseline and week 9
|
BMI will be computed as weight in kilograms divided by height in meters squared.
Weight Status will be determined using standard CDC BMI categories.
|
Baseline and week 9
|
Body Composition
大体时间:Baseline and week 9
|
Fat mass (kg), fat free mass (kg), and percentage body fat will be determined by bioelectrical impedance analysis using the InBody 520 analyzer.
|
Baseline and week 9
|
waist circumference
大体时间:Baseline and week 9
|
Waist circumference will be measured at the border of the iliac crest using a Gulick II tape measure.
|
Baseline and week 9
|
Blood Pressure
大体时间:Baseline and week 9
|
Systolic and diastolic blood pressure will be measured in duplicate in the right arm after 10 minutes of seated rest using the Omron HEM-907XL Professional Digital Blood Pressure Monitors (Omron Healthcare, Kyoto, Japan).
One minute rest will be provided between the 2 measurements.
|
Baseline and week 9
|
Fasting plasma glucose
大体时间:Baseline and week 9
|
Fasting plasma glucose will be measured from a fingerstick blood sample in the morning after an overnight fast using the Cholestech LDX System® (Hayward, CA).
|

|
Total Cholesterol
大体时间:Baseline and week 9
|
Total cholesterol will be quantified from a fingerstick blood sample in the morning after an overnight fast using the Cholestech LDX System® (Hayward, CA).
|
Baseline and week 9
|
LDL Cholesterol
大体时间:Baseline and week 9
|
LDL cholesterol will be computed using the Friedewald equation from the lipid profile measured from a fingerstick blood sample in the morning after an overnight fast using the Cholestech LDX System® (Hayward, CA).
