Integrated lifestyle intervention for physical activity and weight management

Designing With Dissemination in Mind: Development and Evaluation of a Theory-based Physical Activity Intervention Using the Multiphase Optimization Strategy: Aim 2

This study is testing a new program that combines group classes and personal support to help adults who are overweight and not very active improve their physical activity and manage their weight.

What this trial studies

This pilot trial aims to evaluate the feasibility and acceptability of incorporating the Move physical activity support program into an existing lifestyle intervention designed for individuals struggling with physical inactivity and obesity. Participants will engage in group-based classes, receive fitness memberships, and have access to mental imagery and one-on-one support. The study targets adults aged 18-65 with a BMI between 25-45 kg/m2 who are insufficiently active. The intervention will be delivered in English and requires participants to have access to technology for engagement.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adults aged 18-65 with a BMI of 25-45 kg/m2 who are insufficiently active.

Not a fit: Patients who are already enrolled in other formal weight loss or physical activity programs may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could help patients achieve significant weight loss and improve their physical activity levels.

How similar studies have performed: Other studies have shown success with integrated lifestyle interventions for obesity and physical inactivity, suggesting this approach is promising.

Eligibility criteria

Inclusion Criteria:

* For all types of research participants:

  * Men and Women
  * Age 18-65 years
  * Have access to a computer and/or smart phone, and Wi-Fi
  * Speak English (since all study materials are in English and the intervention will be delivered in a group-class setting with a coach who speaks English, we are only able to accommodate English-speakers at this time)
* For the patient participants only:

  * Body Mass Index 25-45 kg/m2
  * Insufficiently active (defined as \<150 min/week of voluntary exercise at moderate intensity over the past 3 months)
  * Willing not to enroll in any other formal weight loss, or physical activity program over the next 5 months.
  * Have a primary care physician (or has access to a healthcare professional and/or are willing to establish care with a primary care physician prior to study enrollment) to address medical issues which may arise during screening or study procedures/interventions.
  * Capable and willing to give informed consent, understand exclusion criteria, attend the Move program sessions, and complete outcome measures.
* For the provider participants only:

  * \>1 year experience with delivering lifestyle interventions involving changes in diet and/or exercise behaviors.

Exclusion Criteria:

* For patient participants:

  * Considered high risk, based on the American College of Sports Medicine Guidelines for Exercise Testing and Prescription (i.e. have cardiovascular disease symptoms or known cardiovascular disease, diabetes, or end-stage renal disease).
  * Females who are currently pregnant or lactating, were pregnant within the past 3 months, or planning to become pregnant in the next 5 months will also be excluded
  * Self-reported cardiovascular disease:
  * Cardiac, peripheral vascular, or cerebrovascular disease
  * Self-reported symptoms suggestive of cardiovascular disease: pain, discomfort in the chest, neck, jaw, arms, or other areas that may result from cardiac ischemia; shortness of breath at rest or with mild exertion; dizziness or syncope; orthopnea or paroxysmal nocturnal dyspnea; ankle edema; palpitations or tachycardia; intermittent claudication
  * Self-reported end-stage renal disease
  * Self-reported diabetes (history of type 1 or type 2 diabetes)
  * Uncontrolled hypertension, defined as diastolic blood pressure \>100 mmHG, systolic blood pressure \>160 mmHG, or resting heart rate \>100 bpm as measured in duplicate at the screening visit after 5 minutes of rest in a seated position.
  * Self-reported pulmonary disease requiring chronic oxygen supplementation; severe asthma or chronic obstructive pulmonary disease requiring hospitalization in past year.
  * Plans to relocate in the next 16 months
  * Currently participating in or planning to participate in any formal weight loss, dietary modification, or physical activity/exercise programs or clinical trials.
  * Current severe depression or history of severe depression within the previous year, based on Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) criteria for Major Depressive Episode. Score \> 18 on Beck Depression Inventory (BDI) will require further assessment by the Study Medical Doctor (MD) to determine if it is appropriate for the subject to participate in the study.
  * History of other significant psychiatric illnesses (e.g., psychosis, schizophrenia, mania, bipolar disorder) which in the opinion of the Study MD would interfere with ability to adhere to the exercise intervention.
  * History of clinically diagnosed eating disorders including anorexia nervosa, bulimia, binge eating disorder. Score \>20 on the Eating Attitudes Test (EATS-26) or pattern of response on the Questionnaire on Eating and Weight Patterns-5 (QEWP-5) suggestive of possible binge eating disorder or bulimia will require further assessment by the Study MD to determine if it is appropriate for the subject to participate in the study.
  * Current alcohol or substance abuse
  * Nicotine use (current or past 6 months)
  * Regular use of prescription or over-the-counter medications known to significantly impact appetite, weight, sleep, or energy metabolism (e.g., appetite suppressants, lithium, stimulants, anti-psychotics, tricyclic antidepressants)
  * Regular use of obesity pharmacotherapeutic agents within the last 6 months.
  * Previous obesity treatment with surgery or weight loss device, except: (1) liposuction and/or abdominoplasty if performed \> 1 year before screening, (2) lap banding if the band has been removed \> 1 year before screening, (3) intragastric balloon if the balloon has been removed \> 1 year before screening (4) duodenal-jejunal bypass sleeve, if the sleeve has been removed \> 1 year before screening or 5) AspireAssist or other endoscopically placed weight loss device if the device has been removed \> 1 year before screening.

* For provider participants:

  * None
