研究概览
简要总结
The specific aim of this study is to collect preliminary data on the feasibility and validity of home-based data collection methods to measure four constructs:
- Physical Activity: Real-time assessment using Ecological Momentary Assessment (EMA) and pedometers
- Cardiorespiratory Fitness: Step test
- Anthropometry: Waist and hip circumference measurements
- Environmental Variables: Examples include density of neighborhood physical activity facilities (including gyms, parks, walking trails), crime, land use mix, and transportation variables, collected by participants using EMA.
详细描述
SCREENING PHONE CALL:
If you are interested in taking part in this study, the study staff will contact you by phone and you will answer questions about your physical ability to exercise. Based on the answers you give, the study doctor will decide if you are eligible to participate. The phone call will last about 10-15 minutes.
STUDY PROCEDURES:
If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to complete physical activity recall and environmental assessments on a palm pilot either 3 times a day or once a day. For the physical activity recall assessment, you will describe what types of physical activity you did that day. The environmental assessments will be to describe your current location or environment. It should take less than 5 minutes to complete each assessment.

研究组 & 干预措施
Physical Activity Recall
Hand-held computers will be used to record information for 7 days about physical activity. Assessments will be completed either 3 times a day or once a day.
干预措施: Physical Activity Recall (Behavioral)
Environmental Assessment
Environmental assessments on a palm pilot either 3 times a day or once a day. Hand-held computer programs will be used to collect information about the community. Some factors will be assessed only once (e.g., availability of facilities) while other information will be collected over the course of 7 days (e.g., perceptions of neighborhood safety).
干预措施: Environmental Assessments (Behavioral)
结局指标
主要结局
Feasibility of home-based data collection methods: Percentage of Participants Completing Step Test
时间窗: 3 Years
Feasibility measured by the percentage of participants who have adequate cardiorespiratory fitness (i.e., V02 max greater than or equal to 31) to perform the step test. Researchers will consider the test feasible if greater than or equal to 75% of the participants have adequate fitness to perform the test.
