Foot tape measure for identification of low birth weight newborns
1K.E.M. Hospital Research Center, Rasta Peth, Pune.
The majority of births in rural India take place at home, Logistic constraints make early and reliable identification of low birth weight babies difficult. Using neonatal foot length as a proxy measure for birth weight, we devised a tri colored foot tape intended for use at home by the neonatal caretaker or birth attendant. The tape was field tested in a rural community in the Pune district. Results showed a sensitivity of 68.2% and a predictive value of 45.5% for identifying low birth weight. For very low birth weights (< 1500 g) the sensitivity was 100%, specificity 95.2% and the positive predictive value 60%. Interobserver reliability comparing a trained medical social worker and the household member was high (kappa score of 0.82). If implemented on a larger scale this simple, low cost technology has the potential to significantly enhance the yield of identification of low birth weight babies born at home.
