View original scientific description
The purpose of this study is determine the effectiveness of a six-month virtually-delivered dietary education intervention (PEDALL) on the prevention of overweight and obesity (OW/OB) during maintenance chemotherapy in children and adolescents with acute lymphoblastic leukemia (ALL).
Interventions
BEHAVIORAL
PEDALL
Twenty-six hour nutrition education intervention delivered virtually over a six month period
OTHER
Standard of care
Nutrition education per institutional standard of care
Primary outcome measures
To prevent the development of OW/OB during maintenance chemotherapy using a six-month virtually delivered dietary education intervention (PEDALL) in English and Spanish speaking families of children and adolescents undergoing treatment for ALL.
Time frame: 3.5 years
Number of participants with overweight or obesity as assessed by body mass index (BMI) for age z-scores \>1 will change from baseline following 6 month virtual diet education intervention. BMI z-score will be evaluated at the end of 6-month intervention in the maintenance phase of ALL therapy. BMI z-scores will be classified by comparing age, sex, height and weight to CDC growth charts. OW is defined as BMI z-score ≥ +1.04 , and OB is defined as BMI z-score ≥ +1.645 . For participants ≥20 years of age, adult classifications will be used to determine weight status as recommended by the CDC and include BMI \< 19 underweight; BMI 19-\<25 healthy weight; BMI ≥ 25 - \<30 overweight; BMI ≥ 30 obese.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
