Healthy Bones, Healthy Life: Habitual Physical Activity on Bone & Metabolic Health in Pediatric Cancer Survivors (HBHL)
December 18, 2023 updated by: University of Nebraska
Healthy Bones, Healthy Life: Effect of Habitual Physical Activity on Bone and Metabolic Health in Pediatric Cancer Survivors
This project will examine habitual physical activity, bone health, and insulin resistance in pediatric acute lymphocytic leukemia (ALL) and lymphoma cancer survivors at two time points: baseline and 6 months.
At the two study timepoints, all study participants will be asked to wear an accelerometer, receive a DXA scan of the lumbar spine and hip, and have blood drawn for analysis.
Study participants will be given a gift card stipend for each study visit attended.
Study visits will coincide with regular office visits to Children's Hospital Oncology Clinic and the Children's Hospital Survivorship Clinics whenever possible.
The potential mechanism by which physical activity mediates bone changes will be explored by concurrently measuring changes in lean/fat mass and metabolic status.
This pilot study will provide data to inform the design of a randomized controlled trial to test the effect of a physical activity intervention on bone health in PCS.

Detailed Description
Childhood cancer treatments are increasingly effective, leading to dramatic improvements in survival rates.
These treatments often have devastating effects on the overall health of pediatric cancer survivors (PCS) since they occur during a critical time of bone growth, including increased risks of poor bone health, fracture, and diabetes.
In normal child development, physical activity habits influence bone density and structure, which affect bone strength in adulthood.
Despite this well-understood principle of bone development, there are no exercise guidelines for improving bone health in PCS.
The long-term goal of this research is to develop an effective exercise intervention to improve bone health after cancer therapy.
As a first step, the investigators propose to test the hypothesis that the intensity and amount of ground impact of a child's daily physical activity will influence changes in bone density in PCS.
The Specific Aims are to (1) examine the effect of physical activity on lumbar bone density of PCS and to (2) evaluate how physical activity influences bone density.
In a prospective cohort study, the investigators will enroll 38 pediatric and adolescent survivors (ages 5-18) of acute lymphoblastic leukemia or lymphoma at any post-treatment time point.
Aim 1: At two assessments, baseline and six months later, bone density and structure (by DXA scan, a type of x-ray that can measure bone density and the amount of muscle and fat in the body) and physical activity level (by accelerometry, a device like a fitness tracker) will be evaluated.
Each child will be categorized as having low or high physical activity based on accelerometry measures averaged from baseline and six-month assessments.
Bone changes (0-6 months) will be compared between low and high activity groups.
Aim 2: Evaluate potential mechanisms by which physical activity mediates changes in bone, including the effects of lean mass (measured by DXA) and metabolic health (lipid panel, insulin sensitivity (HOMA-IR, hemoglobin A1c), vitamin D).
Long-term impact: This research will provide information as to the types of exercise that impact bone health in PCS.
This study will help develop effective, evidence-based exercise therapies.
These therapies may help prevent fractures and associated disability, leading to an improvement in the quality of life for survivors of pediatric cancer.
