Sleep restriction decreases the physical activity of adults at risk for type 2 diabetes.

ABSTRACT:

Study objective

To test the hypothesis that recurrent sleep curtailment will result in decreased physical activity in adults at risk for type 2 diabetes.

Design

Two-condition 2-period randomized crossover study.

Setting

University General Clinical Research Center.

Participants

Eighteen healthy patients with parental history of type 2 diabetes (9 females and 9 males, age 27 yr [standard deviation 3], body mass index 23.7 [2.3] kg/m²).

Interventions

Two week-long inpatient sessions with 8.5 or 5.5-hr nighttime sleep opportunity. Participants who exercised regularly (39%) could follow their usual exercise routines during both sessions.

Measurements and results

Sleep and total body movement were measured by wrist actigraphy and waist accelerometry. Su
