The CREATE summer internship program at the University of Hawaiʻi Cancer Center concluded its 2024 session on July 26 with poster presentations showcasing intern research. The Shepherd Research Lab hosted Atasha Bautista, an undergraduate from the University of Guam, who investigated body-composition measurement methods for infants.

Project overview

Bautista’s research centered on testing a baby phantom using three measurement technologies: 3D Optical Scanners, BODPOD, and PEAPOD. She prepared the phantom based on actual 3DO scans of babies, painting it in various Fitzpatrick skin-tone categories, then compared measurement results across systems.

Key findings

Testing revealed that 3DO scans showed declining success with darker-skinned babies. Adjustments to the 3DO system have already been implemented to improve performance with darker skin tones, with further validation planned.

When comparing volumetric measurements, the PEAPOD demonstrated consistent results while the BODPOD produced variable readings. This suggests potential BODPOD limitations when measuring smaller children and raises questions about optimal measurement approaches for infants exceeding PEAPOD capacity.

Research impact

Findings directly informed the Shape Up! Keiki study, which measures body composition in children ages 0–5 on Oʻahu. The research improvements enhance data quality and inclusivity across diverse populations.

Program background

The CREATE internship — supported by a National Cancer Institute grant (R25CA244073) and Meiji Yasuda Life Insurance Company endowment — provides Pacific-region students research experience. Bautista plans to pursue medical school and credited the program with advancing her research skills and professional development.
