| Conditions: |
|
-Obstructive Sleep Apnea |
| Purpose: |
|
The overall goal of this study is to determine the efficacy of a lifestyle intervention,
consisting of a weight loss diet and exercise on sleep apnea in older adults. The
investigators will conduct a 3-month intervention in men and women who are sedentary with
suspected sleep apnea. The investigators hypothesize that the intervention will lead to
marked improvements in sleep apnea severity and cardiovascular risk markers.

| Study Summary: |
|
Frailty, a condition characterized by a decrease in physiological reserve and increased risk
for adverse health-related outcomes, is an increased risk of aging, especially in the
presence of co-morbid conditions. Sleep apnea is also highly prevalent with increasing age.
Both conditions share common pathologies, suggesting that sleep apnea may increase the risk
of developing or exacerbate the consequences of frailty. Lifestyle interventions as
strategies for treating sleep apnea and associated co-morbidities, thereby highlighting a
feasible approach by which to reduce the incidence or progression of frailty. The specific
aims of this study are to: 1) determine the effectiveness of a lifestyle intervention (LI),
consisting of a weight loss diet and supervised exercise, on reducing sleep apnea in older
adults, and 2) determine whether this intervention is effective at improving parameters that
are common to both sleep apnea and frailty, such as poor physical functional capacity and
body composition, impaired or abnormal cardiometabolic function and increased levels of
inflammation.
