This proposal aims to study the issues of health behaviors in the domains of diet, exercise, stress, and sleep. We aim to improve health behaviors in these domains by evaluating lifestyle choices and communication preferences with a three phase investigation. Phase 1 has the specific objective of lifestyle assessment. Phase 1 will evaluate dietary habits and choices, exercise practices, perceived stress levels, and quantity and timing of sleep utilizing a web-based health survey. The web-based survey tool will populate a secure research database. The data will include demographic information, anthropometric data, actigraphic data to measure exercise levels and sleep time, and laboratory studies that measure glucose metabolism, lipids, and other laboratory markers for cardiovascular risk assessment.
Phase 2 constitutes a pilot study in a limited number of university students to determine the feasibility of causing healthy behavior change with the use of electronic messaging to university students up to six times per week over 8 weeks. Experience from this feasibility study will inform the design of Phase 3.
Phase 3 will measure improvements in the lifestyle behaviors of students as a result of health coaching and electronic feedback messages over an 8 week period comparing their indices of health with a control group that does not receive the coaching and electronic feedback messages. Utilizing lessons learned from Phase 2, subjects randomized to an intervention arm but not subjects randomized to a control arm, will receive health coaching and electronic messages at the rate of up to six times per week over an 8 week period. Before and after this intervention period, measurements of lifestyle choices, anthropometrics, actigraphy for objective exercise and sleep patterns, and cardiac-relevant laboratory studies will be measured. Data from the intervention group will be compared with that of the control group.
