Summary

The purpose of this study is to determine whether the researchers can help people change the amount of time they spend in sitting activities and whether this change might improve health outcomes.

Detailed description

Specific Aim 1: Determine feasibility of a 12-week home and telephone based intervention in older adults with mild cognitive impairment targeting both the impaired individual and their study partner to help initiate and maintain behavior change. We will recruit KUADC registry participants with MCI and their caregivers (as study partners). Behavioral interventions are more effective when there is built in social support. We will evaluate feasibility in terms of successful recruitment and retention of participants, 10% or less of technological failures, rate of participant concerns addressed by phone and at home visits, acceptability of the intervention to participants (measured by questionnaires during home visits). Specific Aim 2: Determine whether a 12-week home and telephone based intervention results in reduced total sitting time and shorter bouts of sitting in older adults with MCI and their caregivers. Electronic postural monitors will record sitting time for a duration of one week at three time points (pre-intervention, mid-intervention, and post-intervention). The intervention includes 1) feedback from baseline monitoring, 2) educational and goal setting session with the participants and research staff, 3) wrist worn monitors that alert wearers to sitting times \>30 minutes, 4) home and telephone visits to address physical, psychological, and home environment barriers to behavior change. Changes in sitting time and breaks from sitting will be compared between baseline, mid-intervention, and post-intervention measurement occasions. Specific Aim 3: Determine whether sedentary behavior intervention results in improved insulin sensitivity and glycemic control. To evaluate whether reduced sitting results in meaningful metabolic changes, we will measure postprandial insulin and glucose, and body composition, and evaluate changes from pre- to post- intervention adjusting for relevant covariates.

Type	Name	Description
DEVICE	Jawbone Up	Jawbone Up is a wrist wore water resistant activity monitor.
BEHAVIORAL	Physical Activity Education	A study team member will discuss benefits of changing sitting habits and ways to make changes to personal habits.
