Not Applicable
Completed
Conditions
Sedentary Lifestyle
Interventions
Device: ActivPAL inclinometer
Other: Tools to prompt standing
Registration Number
NCT02905929
Lead Sponsor
University of California, San Diego
Brief Summary

Project 2 of the University of California, San Diego (UCSD) American Heart Association (AHA) Women's Health Program will assess 3-month changes in sitting time, standing time, physical activity and blood pressure in a randomized control trial (RCT). This 2-arm RCT will occur in the community with post menopausal Latina women (N=250) who spend at least 8 hrs/day sitting and have increased risk for cardiovascular disease through high BMI and other cardiometabolic risk factors. Women will be identified through the San Ysidro Health Center and assessed at the South Bay Latino Research Center.

Detailed Description

Project 2 will address the following aims:

1. Investigate the 3 month effect of the intervention to impact the primary behavioral outcomes of sitting, standing and stepping time assessed objectively by a thigh worn inclinometer (ActivPAL) in Latinas at risk for heart disease.

2. Investigate the 3 month effect of the intervention to impact the secondary health outcomes of blood pressure, depressive symptoms, and anthropometrics.

3. Explore the psychosocial \& environmental mediators \& moderators of changes in sitting time.

GroupInterventionDescription
Sitting Less groupTools to prompt standingThe 'reduce sitting' intervention group will receive three in-person health coaching sessions followed by five counseling phone calls. Participants will wear a thigh worn inclinometer for the first 3 weeks of the intervention, and at the mid-point of the intervention. At each in-person health coaching session participants will receive feedback from the ActivPAL showing periods throughout the day where participants have been sitting. In addition to the three initial in-person counseling sessions using the ActivPAL feedback, participants will receive phone calls from the health educator biweekly to help overcome barriers, to work on self-monitoring and planning skills, and to prepare relapse prevention. Tools to help prompt standing, including a standing desk, will also be provided.

Primary Outcome Measures
NameTimeMethod
Sitting, standing and stepping time3 months

Change in daily time spent sitting, standing and stepping during waking hours as measured objectively by the ActivPAL

Secondary Outcome Measures
NameTimeMethod
Psychosocial and environmental mediators: habit formation3 months

Assessed using the Self-Report Habit Index

Anthropometrics3 months

Change in body mass index (BMI)

Psychosocial and environmental mediators: benefits and barriers3 months

Investigators will use measures adapted for our pilot that include benefits and barriers to sitting less.

Psychosocial and environmental mediators: self-efficacy3 months

Investigators will use measures adapted for our pilot including self-efficacy to sit less.

Demographic moderators: retirement status3 months

Self-reported items on the baseline survey. Some of these demographic variables will also be considered covariates in analyses.

Demographic moderators: age3 months

Self-reported items on the baseline survey. Some of these demographic variables will also be considered covariates in analyses.

Demographic moderators: education3 months

Self-reported items on the baseline survey. Some of these demographic variables will also be considered covariates in analyses.

Blood pressure3 months

Change in blood pressure

Depressive symptoms3 months

Change in depressive symptoms, measured with Center for Epidemiologic Studies Depression (CESD) short form. Scores greater than 10 indicate probable depressive symptoms.

Psychosocial and environmental mediators: home environment support3 months

Investigators will use measures adapted for our pilot including home environment support surrounding sitting less.

Improvement in Quality of Life3 months

Change in quality of life, measured with the EURO-QOL 5-D, a brief 5 item standard scale that has demonstrated validity in populations with diabetes and cardiovascular diseases.

Psychosocial and environmental mediators: social support3 months

Investigators will use measures adapted for our pilot including social support surrounding sitting less.

Demographic moderators: sex3 months

Self-reported items on the baseline survey. Some of these demographic variables will also be considered covariates in analyses.

Demographic moderators: marital status3 months

Self-reported items on the baseline survey. Some of these demographic variables will also be considered covariates in analyses.
