Lifestyle Intervention for Sleep Disturbances Among Overweight or Obese Individuals

Abstract

Little is known about the effect of different lifestyle interventions on sleep disturbances among sedentary obese or overweight persons. We randomized men and women aged 35–65 to 6 months of a weight loss diet (D); or D combined with supervised exercise training Measurements were self-reported sleep disturbances, the Profile of Mood States questionnaire, BMI, total abdominal subcutaneous and visceral fat by magnetic resonance imaging, and aerobic fitness expressed as VO₂peak. The groups did not differ in changes for body weight, abdominal total fat, VO₂peak, and sleep disturbances. The novel finding herein is that reduced abdominal subcutaneous fat and depressive symptoms, with either D or were associated with less sleep disturbances.
