简要总结
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).
详细描述
Acute lymphoblastic leukemia (ALL) has been referred to as a "pre-obese state", with many studies describing the onset of obesity during treatment. Weight gain typically begins within the first month of ALL diagnosis, stabilizes, and then resumes at the beginning of maintenance and continues into survivorship. Children and adolescents with healthy weight at diagnosis are the most vulnerable to weight gain; up to 70% develop overweight/obesity (OW/OB) by the end of treatment (EOT). Weight gain during treatment is one of the most consistently reported risk factors for weight gain in survivorship and is associated with an increased odds of being OW/OB 5-years post-EOT. Significant clinical ramifications are associated with being OW/OB. A meta-analysis led by the Children's Oncology Group nutrition committee found that OW/OB is associated with a 31% increased risk of mortality in ALL.
The objective of the study team is 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. Once enrolled, subjects will be randomized to PEDALL or standard of care (SOC). Subjects in the PEDALL group will receive 26 contact hours of specialized nutrition education and counseling via a virtual platform.
The purpose of this study is to determine the effectiveness of a virtually-delivered dietary education intervention in the prevention of OW/OB compared to SOC during maintenance chemotherapy. The clinical impact of this study will improve the understanding of pre-treatment factors predictive of the efficacy of intervention to prevent unhealthy weight gain among patients treated for ALL. Study findings may lead to the allocation of limited clinical resources to individuals most susceptible to OW/OB. Information obtained from this study may also direct the refinement of counseling techniques to enhance the likelihood of success over the course of treatment for ALL and into survivorship. The long-term goal is to enhance the likelihood of success of weight maintenance during therapy thereby mitigating excess toxicities during treatment and reducing nutrition-related late-effects associated with OW/OB among survivors of childhood ALL.

结局指标
主要结局
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.
时间窗: 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.
次要结局
- The modifying effect of multi-level sociodemographic factors on the efficacy of PEDALL for the prevention of OW/OB in children and adolescents undergoing treatment for ALL.(4 years)
- The effect of intervention on BMI z-score trajectories over time (from time zero to one-year post-completion of treatment for ALL) and modification of this effect by genetic and sociodemographic factors.(4 years)
- The modifying effect of genetic predisposition to OW/OB, defined by a genome-wide polygenic score (GPS) for obesity optimized for Hispanic and Non-Hispanic application, on the efficacy of PEDALL intervention(4 years)
- Understand contextual factors that shaped the recruitment and retainment of participants and to identify strategies that may hinder or support implementation within routine care at sites(4 years)
- The effect of intervention on reported lifestyle behaviors as measured by World Cancer Research Foundation/American Institute for Cancer Research lifestyle guidelines.(4 years)
- Understand individual factors and site-specific factors that shaped both experience with and response to the intervention using a one-time, brief open-ended questionnaire to patients and caregivers.(4 years)
