Brief Summary: Cardiovascular disease accounts for 1 in 3 deaths among US adults and is strongly related to physical activity. Most older adults do not participate in healthy levels of physical activity. Physical activity promotion and counseling from a primary health care provider is important for disease prevention. In addition to counseling, an activity monitor can increase physical activity through self-regulation. Two types of monitors are available: pedometers and electronic activity monitors (EAMs). Research shows that both monitors are motivational devices that can increase physical activity. Pedometers count steps of the wearer. EAMs can monitor steps, monitor burned calories, quality of sleep, and sedentary time. EAMs may also offer more behavioral change techniques and opportunities for self-monitoring. The goal of this study is to compare the effectiveness of EAMs compared to a pedometer on increasing physical activity and decreasing cardiovascular risk within older adult, primary care patients. The study will include sedentary, overweight primary care patients, 55-74 years of age with access to a smart phone or tablet. All participants will receive brief physical activity counseling. Participants will then be randomized to receive a self-monitoring device (Digi-walker CW-700/701 or UP24 by Jawbone) to wear for 3 months. Investigators will evaluate the following outcomes: physical activity, cardiovascular risk (Framingham risk calculator, fitness), psychological feeling toward exercise, physical function, health status, exercise motivation and self-regulation. The investigators hypothesize that EAMs will be more effective than pedometers in improving these outcomes. The results of this pilot test will aid in the translation of effective physical activity intervention components to primary care clinics for cardiovascular disease prevention.

Detailed Description: Cardiovascular disease (CVD) is prevalent and the leading cause for mortality in the United States. The American Heart Association's (AHA) 2020 Impact Goal is to improve the cardiovascular health of all Americans by 20 percent while reducing deaths from CVD and stroke by 20 percent. Maintaining healthy levels of physical activity (PA) is critical in maintaining cardiovascular health, but older adults are inactive. Inactivity may be influenced by low levels of motivation. Standard behavioral counseling techniques typically implemented within the primary care setting target increased motivation, but lack the key component of self-control. The addition of electronic activity monitors (EAMs) that provide interactive self-monitoring, feedback, and social support may further increase motivation for exercise by providing more effective behavior change techniques than standard protocols. Investigators will conduct a three month intervention trial that will test the feasibility of adding an EAM system to brief counseling within a primary care setting. Participants (N = 40) will be randomized to receive evidence-based brief counseling plus either an EAM or a pedometer. Investigators propose two Specific Aims:

AIM 1: Evaluate the feasibility and acceptability of implementing a technology-enhanced brief intervention to increase physical activity in a primary care setting. Measures of feasibility will include days the EAM was worn, usage of the app, technological problems, attrition, and adverse events. Acceptability will be measured by self-report and focus groups.

AIM 2: Compare the counseling plus EAM intervention to a counseling plus pedometer intervention. Primary outcomes will be changes in PA and cardiovascular risk. We will also investigate secondary outcomes (differences in adherence, weight and body composition, health status, motivation, physical function, psychological feelings, self-regulation).

Primary Outcome Measures

Name	Time	Method
Composite Measure for Cardiovascular Risk Measured by the Framingham Non-laboratory Risk Calculator	Cardiovascular risk at the end of the 12 week intervention	Factors within the risk calculator include of age in years, systolic blood pressure, gender, and body mass index. These factors are used to create a composite score to estimate the individual's risk for a cardiac event within the next 10 years. The risk score is not bound by maximums and minimums, however a lower number is more favorable. Among women, a composite risk score of 10 equates to a 6% risk of a cardiovascular event, a risk score of 15 equates to a 13% risk, a risk score of 20 equates to a 28.5% risk, and a risk score of 21 or higher equates to \>30% risk of a cardiovascular event within the next 10 years. Among men, a composite risk score of 10 equates to a 9% risk, a risk score of 15 equates to a 21.5% risk, and a risk score of 18 or higher equates to \>30% risk of a cardiovascular event within the next 10 years.
6-minute Walk Test	Fitness at the end of the 12 week intervention	distance walked in 6 minutes
Steps Per Day	Steps per day at the end of the 12 week intervention	Measured by a SenseWear Armband. Average steps per day over a 7 day period
Physical Activity Minutes Measured by a SenseWear Armband	Physical activity minutes at the end of the 12 week intervention	Minutes of moderate-vigorous physical activity over a 7 day period

Secondary Outcome Measures

Name	Time	Method
Waist-to-Hip Ratio	Waist-to-hip ratio at the end of the 12 week intervention	Waist-to-Hip ratio was calculated by divided the waist circumference (in inches) by the hip circumference (in inches).
Psychological Feelings	Psychological feelings at the end of the 12 week intervention	Measured by the Psychological Need Satisfaction in Exercise Scale. Sub-scales include perceived competence, perceived autonomy, and perceived relatedness. Each sub-scale had a range from 1 to 5. Higher scores, in each sub-scale, represent a more favorable outcome.
Resting Pulse	Resting pulse at the end of the 12 week intervention
Weight	Weight at the end of the 12 week intervention
Body Mass Index (BMI)	BMI at the end of the 12 week intervention
Blood Pressure	Blood pressure at the end of the 12 week intervention
Exercise Motivation	Exercise motivation at the end of the 12 week intervention	Measured by Behavioral Regulation in Exercise Questionnaire-2. Sub-scales include intrinsic, identified, introjected, extrinsic, and amotivation. Each subscale ranges from 0 - 4, with 0 being lowest and 4 being highest level of motivation for the given subscale. The different subscales measure varying forms of autonomous motivation; therefore high scores (maximum of 4) of "intrinsic" and "identified" are better. Alternatively, low scores of "introjected", "extrinsic", and "amotivation" are better.
Quality of Life Measured by the SF-36 Questionnaire	Quality of life at the end of the 12 week intervention	Sub-scales include physical functioning, social functioning, physical role limitations, emotional role limitations, mental health, energy/vitality, and pain. All sub-scales have a range of 0 to 100. High scores and scores closer to 100 represent a better outcome for each sub-scale.
Change From Baseline in Self-regulation	Change in self-regulation from baseline and 12-weeks	Measured by the Rovinak et al scale. Sub-scales include exercise goals and exercise plans. The possible scores on both subscales range between 10 and 50, with higher scores representing more favorable outcomes in exercise goals and planning.
Physical Function Measured by the Short Physical Performance Battery	Physical function at the end of the 12 week intervention	Physical function is operationalized by 3 functional tests, including repeated chair stands (5 consecutive stands), balance (semi-tandem stand, side-by-side stand, tandem stand) and 8 feet walk. The time it took for participants to complete each test was timed in seconds. The faster the repeated chair stand and 8 feet walk tests were performed, the better the function of the individual. Therefore, lower scores represent a better outcome. These tests were not bound by maximums. The higher score for tandem balance, maximum of 10, represents a better outcome. The balance test is comprised of three positions but time is only recorded for one. Participants start with the semi-tandem, then if they are able to hold the position for 10 seconds they continue to tandem balance test. If they are not able to hold the semi-tandem position for 10 seconds, they then complete the side by side test. In this study, all participants proceeded to the tandem test, so outcome is labeled "tandem balance."
