Feasibility of a Sleep Improvement Intervention for Weight Loss and Its Maintenance in Sleep Impaired Obese Adults

Obesity Clinical Trial

Official title: A Pilot Study to Assess the Feasibility and Adherence of a Sleep Improvement Intervention for Weight Loss and Its Maintenance in Sleep Impaired Obese Adults

Status Recruiting

Clinical Trial Summary

The primary objective of the proposed study is to develop, deliver and assess the feasibility and adherence to a targeted behavioral sleep intervention for sleep impaired obese patients.

Secondary objectives are to demonstrate that a targeted behavioral sleep intervention can improve treatment outcomes in obese adult outpatients enrolled to a lifestyle and dietary modification program; and to demonstrate that a targeted behavioral sleep intervention enhances the long-term maintenance of treatment gains in obese adults enrolled in a lifestyle and dietary modification program.

Those with sleep impairment (sleep duration of ≤6.5hours per 24-hours; and/or poor sleep quality [<85% efficiency]; and/or misaligned nocturnal sleep timing [>03:00 on weekdays]) who are also obese (Body Mass Index [BMI] ≥27.5 kg/m2) will be recruited and randomized to a 12-week weight loss intervention with/without sleep improvement. Volunteers will be followed for a further six months to assess multiple outcome measures.

It is hypothesised that inclusion of a targeted behavioral sleep improvement intervention will be feasible and acceptable and will enhance immediate and long-term treatment outcomes of obese adults enrolled to a lifestyle and dietary modification program. The results of the study will be used to better inform the design and development of a future Randomized Controlled Trial (RCT).

Sleep improvement may be incorporated into weight management treatments as a cost-effective alternative/addition.

Clinical Trial Description

Secondary objectives are to demonstrate that a targeted behavioral sleep intervention can improve treatment outcomes in obese adult outpatients enrolled to a lifestyle and dietary modification program; and to demonstrate that a targeted behavioral sleep intervention enhances the long-term maintenance of treatment gains in obese adults enrolled in a lifestyle and dietary modification program.

Those with sleep impairment (sleep duration of ≤6.5hours per 24-hours; and/or poor sleep quality [<85% efficiency]; and/or misaligned nocturnal sleep timing [>03:00 on weekdays]) who are also obese (Body Mass Index [BMI] ≥27.5 kg/m2) will be recruited and randomized to a 12-week weight loss intervention (based on a previously developed specialist lifestyle management program) with/without sleep improvement (based on a cognitive behaviour treatment developed to treatment sleep problems in US military). Volunteers will be followed for a further six months to assess multiple outcome measures. Other secondary measures to be assessed are mood (Hospital Anxiety Depression Scale [HADS], food intake (24-hour food recall), quality of life (IWQOL-LITE & EQ-5D), and sleep (PSQI & RU_SATED), all of which will be assessed using validated questionnaires that have been previously assessed for reliability.

It is hypothesised that inclusion of a targeted behavioral sleep improvement intervention will be feasible and acceptable and will enhance immediate and long-term treatment outcomes of obese adults enrolled to a lifestyle and dietary modification program. The results of the study will be used to better inform the design and development of a future Randomized Controlled Trial (RCT).

Sleep improvement may be incorporated into weight management treatments as a cost-effective alternative/addition. ;
