MEND, on a caregiver's phone

A healthier weight starts at home.

Un peso más saludable empieza en casa.

MEND is a CDC-recognized family healthy weight program: ten weeks in which caregivers and children learn better food and drink choices, more movement, and the parenting and problem-solving skills that make changes stick. CoachMEND brings it to a caregiver's phone, in forty short videos and a coaching assistant grounded in the curriculum.

What MEND is

A whole-family program, not a diet.

Un programa para toda la familia, no una dieta.

MEND stands for Mind, Exercise, Nutrition… Do it! Caregivers and children take part together, and over ten weeks a family practices seven skills.

  • Nutrition food and drink choices
  • Activity more movement, less sitting
  • Parenting praise, modeling, reinforcement
  • Goal-setting small weekly targets
  • Problem-solving working around real barriers
  • Stimulus control changing cues at home
  • Maintenance keeping the changes going

CDC lists the in-person MEND program among its recognized evidence-based Family Healthy Weight Programs, which meet the dose-and-intensity standard the American Academy of Pediatrics recommends.

Caregivers and children take part together.
MEND was designed as a joint program. In CoachMEND, the caregiver runs it; the child never uses the app.

The evidence behind MEND

Tested in a trial. Held up at scale.

Probado en un ensayo clínico. Comprobado a gran escala.

Three findings from the in-person program, which is what CoachMEND is built on.

0.24BMI-z

Greater reduction in BMI-z than wait-list control at six months. The improvement from baseline held at 12 months.

Randomized controlled trial · 116 children
86%

Mean attendance across the program in the same trial. Families showed up.

Randomized controlled trial · 116 children
1.94pts

Greater reduction in %BMIp95 than a primary-care program, among children ages 6–8.

TX CORD · 549 children · 86% Hispanic

These results describe the in-person MEND program. CoachMEND preserves MEND's learning objectives, behavior-change mechanisms, and intended caregiver actions in a different format; it does not claim equivalent contact hours or dose.

Why a phone

The program exists. Reaching it is the problem.

El programa existe. Llegar a él es el problema.

The American Academy of Pediatrics recommends intensive, family-based treatment. Three facts explain why most families never get it.

More than 1 in 5

U.S. children has obesity. Children far from a clinic carry more of that burden.

Fewer sites, longer travel

Intensive programs need a room, a trained team, and two visits a week for ten weeks.

$19,000

more, per child

in estimated lifetime direct medical costs for a 10-year-old with obesity, versus a child who stays at a normal weight.

CoachMEND addresses how families reach and use the program. It doesn't change income, food environments, transportation, or coverage.

How CoachMEND works

One skill a week, applied to your family.

Una habilidad por semana, aplicada a tu familia.

Each week a short video introduces a MEND skill. The caregiver names the barrier that's real at home, and the assistant helps apply that week's skill to it, using only approved MEND content. The next week, the loop starts again.

  • 2–3 minutes each
  • English & Spanish
  • Sixth-grade reading level
  • Plays at 1 Mbps
  • Caregiver-only

Step 2 · Choose

ChooseThe caregiver names the barrier that matters at home this week. Nothing is assigned.

Step 3 · Plan

PlanThe assistant applies the week's skill to that barrier, drawing only on approved MEND content, and turns it into a plan the caregiver can keep in view.

Step 4 · Revise

ReviseA quick check-in closes the week: keep what worked, adjust what didn't, and the next skill is waiting.

Built with boundaries

The assistant stays inside the curriculum.

El asistente se mantiene dentro del currículo.

It answers only from a fixed, version-controlled library of approved MEND content. Anything else gets set wording, not an improvised answer.

  • Helps apply this week's skill to the barrier the caregiver names
  • Hands off with set wording when a question is urgent or out of scope
  • Never diagnoses, recommends treatment, or adds health facts of its own
  • Never talks to children, learns from conversations, or changes without review

Tested to a published standard

Every answer is graded on four criteria before a family sees it.

FAST (Fidelity, Accuracy, Safety, Tone) is a peer-reviewed framework published in Frontiers in Digital Health in 2025, co-authored by CoachMEND's technical lead Paul Sacher and built on a live AI coach used by patients in obesity treatment. Two trained reviewers grade every scenario Acceptable or Unacceptable, with no middle grade, and a panel of pediatric obesity researchers settles disagreements. Nothing ships below 95% acceptable in each language, or with any critical failure.

Who it's for

Families first. Then the systems that serve them.

Primero las familias. Después, los sistemas que las atienden.

Families · Familias

A caregiver and a child, on one phone

  • A caregiver who speaks English or Spanish and has a smartphone
  • A child aged 6 to 13 with a BMI at or above the 85th percentile
  • Coverage through Medicaid or CHIP, with rural families first

Partners · Socios

The organizations these families already know

  • Medicaid managed-care organizations and state Medicaid purchasers
  • Health centers and pediatric systems as deployment partners

Serve families who can't get to an in-person program?

¿Atiende a familias que no pueden llegar a un programa presencial?

If you're a pediatric practice, health center, or Medicaid plan, we'd like to learn how these families reach you and what you would need to see.
