Impact of CPAP on activity patterns and diet in patients with obstructive sleep apnea (OSA).

Study Objectives: Patients with severe OSA consume greater amounts of cholesterol, protein, and fat as well as have greater caloric expenditure. However, it is not known whether their activity levels or diet change after treatment with CPAP. To investigate this issue, serial assessments of activity and dietary intake were performed in the Apnea Positive Pressure Long-term Efficacy Study (APPLES); a 6-month randomized controlled study of CPAP vs.

Effects of exercise and nutritional intake on sleep architecture in adolescents.

Purpose: Few studies have evaluated the relationship between sleep architecture and body mass index (BMI), nutrition, and physical activity in children. This study determined the relationship between sleep architecture and diet and exercise.

Methods: Three hundred nineteen Caucasian and Hispanic children aged 10 to 17 years participated in the follow-up assessment of the Tucson Children's Assessment of Sleep Apnea study.

Caffeine and screen time in adolescence: associations with short sleep and obesity.

Objective: To investigate the associations between sleep duration and obesity incidence and risk factors among pre-adolescents and adolescents.

Design: Cross-sectional study of a community based cohort

Setting: The Tucson Children's Assessment of Sleep Apnea follow-up study (TuCASA) cohort.

Participants: 319 Caucasian and Hispanics between 10-17 years.

Longitudinal association between short sleep, body weight, and emotional and learning problems in Hispanic and Caucasian children.

Study Objective: To determine the impact of lower amounts of childhood sleep assessed by polysomnogram on development of obesity, being anxious or depressed, or having learning problems 5 years later.

Design: Prospective cohort.

Participants: Subjects were 304 community participants from the Tucson Children's Assessment of Sleep Apnea study, aged 6-12 years old at baseline.

Associations of dietary intake and physical activity with sleep disordered breathing in the Apnea Positive Pressure Long-Term Efficacy Study (APPLES).

The purpose of this study was to examine whether dietary habits and physical activity patterns were independently associated with severity of sleep disordered breathing (SDB) in adults diagnosed with obstructive sleep apnea. Data collected from 320 adults participating in an ancillary study of The Apnea Positive Pressure Long-term Efficacy Study were analyzed as a cross-sectional assessment at study baseline. The respiratory disturbance index (RDI) was used as a measure of the severity of sleep disordered breathing.
