Problem being addressed[edit | edit source]

In the absence of appropriate interventions, low birth weight infants are at increased risk for illness, developmental delay and death. Identifying low birth weight children in resource-poor settings requires an inexpensive, accurate and portable scale that can be understood with minimal literacy or training.

Detailed description of the solution[edit | edit source]

The BIRTHweigh III is a portable handheld non-electronic scale that uses a plastic spring to gauge low birth weight status among newborns. Based on WHO cutoff weights and using color codes, the scale categorizes newborns into normal (>2500 g) birth weight, low (2000-2499 g) birth weight, and very low (<2000 g) birth weight. The three-way classification also has applications for correct dosing of antibiotics to newborns.
