Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Diagnosis of mild to moderate IDD as determined by a Community Service Provider operating in Kansas under the auspices of a Community Developmental Disability Organization (CDDO). Participants will be judged competent to provide by their CDDO, or will have a guardian with power of attorney.
  • Ability to provide assent, regardless of guardian consent.
  • of 25 to 45 kg/m2
  • Sufficient functional ability to understand directions, communicate preferences (e.g. foods), wants (e.g. more to eat/drink), and needs (e.g. assistance with food preparation) through spoken language
  • Living at home with a parent/guardian, or in a supported living environment with a caregiver who assists with food shopping, meal planning, and meal preparation and agrees to serve as a study partner
  • No plans to relocate outside the study area over the next 24 months
  • Internet access in the home

Exclusion criteria

Exclusion Criteria:

  • Unable to participate in moderate-to-vigorous physical activity (MVPA)
  • Insulin dependent diabetes
  • Participation in a weight management program involving diet and physical activity in the past 6 months
  • Serious food allergies, consuming special diets (vegetarian, Atkins etc.), aversion to common foods (e.g., unwilling to consume dairy products, vegetables), diagnosis of Prader-Willi Syndrome
  • Pregnancy during the previous 6 months, currently lactating or planned pregnancy in the following 24 months.
  • Serious medical risk, e.g., cancer, recent heart attack, stroke, angioplasty
  • Unwilling to be randomized.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Study arms

  • Active comparator
    In-person Group

    Participants randomized to this group will have a health educator to their house for in-person meetings. Participants will use paper forms to track progress in other parts of the study. Participants will be asked follow the Enhanced Stop Light Diet (eSLD) and take part in structured physical activity each week.

  • Experimental
    Computer Group

    Participants randomized to this group will use an iPad to talk to the health educator via video conference meetings. Participants will use the iPad to track progress in other parts of the study. Participants will be asked follow the Enhanced Stop Light Diet (eSLD) and take part in structured physical activity each week.

Interventions

  • BehavioralVideo Conference Meetings

    Individual video conferencing with a health educator using an iPad.

  • BehavioralIn-person Meetings

    Individual face-to-face (FTF) meetings with a health educator.

  • BehavioralEnhanced Stop Light Diet

    Diet composed of healthy, pre-packaged meals, balance of fruits, vegetables, and low calories snacks, and shakes. Participants and study partners will be trained to use a color coded chart which categorize foods based on the Stop Light system (green, yellow, red) to assist in meal planning, grocery shopping, decisions regarding snack foods, and compliance with the diet in special situations such as eating away from home (restaurants, parties, etc.).

    Also known as: eSLD

  • BehavioralPhysical Activity

    Participants will be asked to complete a set amount of time of moderate-to-vigorous physical activity each week. Participants in the Computer group will be asked to attend remote exercise sessions 2 times a week.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2018 to primary completion in Mar 2021, 36 months.

Results were first posted in Mar 2023, 1 year 11 months after primary completion.

Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 36 months is above that.

Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 7, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
