Sleep During Weight Loss and Weight Loss Maintenance

May 12, 2020 updated by: Jessica.K.Salwen-Deremer, Dartmouth-Hitchcock Medical Center
The purpose of the study is to examine the changes of sleep during weight loss and weight loss management. The research staff will also obtain data on sleep disturbances, insomnia symptoms, risk of sleep apnea, circadian preferences, weight loss self-efficacy, emotional eating, executive functioning, loneliness and social isolation, and patients' beliefs about how sleep might impact their weight control or vice versa.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study is an observational study using a longitudinal data collection design with non-invasive measures. Fifty participants who are about to begin the Healthy Lifestyle Program (HLP) at the Weight and Wellness Clinic (WWC) and another 50 participants who are about to complete HLP will be recruited to the study. After informed consent is obtained, the patient will be asked to complete several questionnaires about sleep and wellbeing. Their height and weight will also be measured by the research staff. The patient will then be given a wrist-worn accelerometer to wear for 16 weeks to measure their sleep and physical activity. They will be asked to complete the same set of questions at approximately the 8th and 16th week at a research visit. Data on existing diagnosis of sleep disorders will be extracted from the patients' electronic medical records.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in sleep duration
Time Frame: Week 1 and 16th week
Sleep parameters measured by the ActiGraph model wGT3X-BT, a wrist-accelerometer. Measured in minutes of sleep per night. Higher number indicating longer sleep duration. Change from week 1 to week 16 will be measured.
Week 1 and 16th week
Changes in physical activity
Time Frame: Week 1 and 16th week
Measured by the Actigraph model wGT3X-BT, a wrist accelerometer. Measured in minutes of moderate to vigorous activity.
Week 1 and 16th week
Change in sleep quality
Time Frame: Week 1, 8th week, and 16th week
Pittsburgh Sleep Quality Index (PSQI) will be used to assess a range of sleep disturbances including insomnia, sleep-related breathing difficulties, and use of sleep aids. A total score of 5 or more is indicative of poor sleep quality. Possible score range is 0-21.
Week 1, 8th week, and 16th week
Change in Severity of Insomnia
Time Frame: Week 1, 8th week, and 16th week
Insomnia Severity Index (ISI) will be used to assess the severity of insomnia symptoms and subjective daytime impairments.The total score ranges from 0 to 63, with higher scores indicating more severe anxiety symptoms.
Week 1, 8th week, and 16th week
Change in Risk for sleep apnea
Time Frame: Week 1, 8th week, and 16th week
The STOP-BANG Questionnaire will be used to assess the patient's risk for sleep apnea. Scores range from 0-8. The higher the score indicates an increase in the probability of sleep apnea.
Week 1, 8th week, and 16th week
Change in Peak alertness
Time Frame: Week 1, 8th week, and 16th week
The Morningness-Eveningness Questionnaire (MEQ) will be used to assess whether the patient's circadian rhythm produces peak alertness in the morning or the evening. Multiple choice, 4-5 point scale. The sum gives a score ranging from 16 to 86; scores of 41 and below indicate "evening types", scores of 59 and above indicate "morning types", scores between 42-58 indicate "intermediate types".
Week 1, 8th week, and 16th week
Change in self-efficacy in one's ability to lose or maintain weight
Time Frame: Week 1, 8th week, and 16th week
The Weight Loss Self-Efficacy Scale will be used to assess self-efficacy in one's ability to lose or maintain weight. Measured by subjective rating percentages of confidence, 0-100%. The higher the percentage the higher the ability to maintain or lose weight.
Week 1, 8th week, and 16th week
Change in strategies to lose weight
Time Frame: Week 1, 8th week, and 16th week
The Weight Control Strategies Scale will be used to assess strategies used to lose weight. The sum of scores ranges from 0-120. The higher the scores the more strategies being used to lose weight.
Week 1, 8th week, and 16th week
Change in emotional and disinhibited eating
Time Frame: Week 1, 8th week, and 16th week
Three Factors Eating Questionnaire will be used to measure emotional and disinhibited eating. Comprised of 18 items , which are aggregated to three separate scale scores. A 4-point response format is used.
Week 1, 8th week, and 16th week
Mood symptoms
Time Frame: Week 1, 8th week, and 16th week
will be assessed using the Patient Healthy Questionnaire (PHQ9). The PHQ9 scores range from 0-27, with lower numbers indicating minimal to no depression and higher numbers indicating severe depression.
Week 1, 8th week, and 16th week
Change in Delayed Discounting Index
Time Frame: Week 1, 8th week, and 16th week
Executive functioning will be assessed using the delay discounting task and the response disinhibition task. K index corresponding to the degree to which a participant discounts future rewards compared to immediate rewards. Will be computed based on a validated algorithm.
Week 1, 8th week, and 16th week
Change in social isolation
Time Frame: Week 1, 8th week, and 16th week
Social isolation will be assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) isolation scale. The PROMIS scale has six items each with a response options ranging in value from one to five. The lowest possible score is 6 and highest possible score is 30.
Week 1, 8th week, and 16th week
Anxiety symptoms
Time Frame: Week 1, 8th week, and 16th week
will be assessed using the Generalized Anxiety Disorder-7 (GAD7). The GAD7 scores range from 5-21, with 5-9 indicating mild, 10-14 moderate, and greater than 15 severe anxiety.
Week 1, 8th week, and 16th week
