“…For LBW along with preterm, newborn foot length <7.3 cm had 86% sensitivity, 83% specificity, 77% positive predictive value, and 90% negative predictive value in making the diagnosis. 16 Srivastata et al reported very strong positive correlation between newborn foot length and gestational age with correlation coefficient 0.99. 15 Different cut-off points in each study and each country suggests that race or country have a role in determining the cut-off point of the foot length.…”

Background Identification of gestational age, especially within 48 hours of birth, is crucial for newborns, as the earlier preterm status is detected, the earlier the child can receive optimal management. Newborn foot length is an anthropometric measurement which is easy to perform, inexpensive, and potentially efficient for predicting gestational age. Objective To analyze the diagnostic value of newborn foot length in predicting gestational age. Methods This diagnostic study was performed between October 2016 and February 2017 in the High Care Unit of Neonates at Dr. Moewardi General Hospital, Surakarta. A total of 152 newborns were consecutively selected and underwent right foot length measurements before 96 hours of age. The correlation between newborn foot length to classify as full term and gestational age was analyzed with Spearman's correlation test because of non-normal data distribution. The cut-off point of newborn foot length was calculated by receiver operating characteristic (ROC) curve and diagnostic values of newborn foot length were analyzed by 2 x 2 table with SPSS 21.0 software. Results There were no significant differences between male and female newborns in terms of gestational age, birth weight, choronological age, and newborn foot length (P>0.05). Newborn foot length and gestational age had a significant correlation (r=0.53; P=0.000). The optimal cut-off newborn foot length to predict full term status was 7.1 cm. Newborn foot length below 7.1 cm had sensitivity 75%, specificity 98%, positive predictive value 94.3%, negative predictive value 90.6%, positive likelihood ratio 40.5, negative likelihood ratio 0.25, and post-test probability 94.29%, to predict preterm status in newborns. Conclusion Newborn foot length can be used to predict gestational age, especially for the purpose of differentiating between preterm and full term newborns.

“…Newborn anthropometric studies have been done in a number of settings, assessing correlation between birthweight and a variety of other measures, including foot-length, and have generally shown reasonably good test characteristics for foot-length [2,12,15,16,17,18]. Although most of these studies did not find foot-length to be the best proxy for birthweight, foot-length measurement has seemed more practical for field use than other measures that generally performed better (e.g.…”

Background: Most newborn deaths occur among those of low birthweight (LBWt), due to prematurity &/or impaired fetal growth. Simple practices can mitigate this risk. In low-income country settings where many births occur at home, strategies are needed that empower mothers to determine if their babies are higher risk and take protective measures. Earlier studies suggest that foot-length may be a good proxy for birthweight. An earlier Nepal study found a 6.9cm cut-off performed relatively well, differentiating normal from low birthweight.Methods: Community-based, cluster-randomized controlled trial. Objective: to determine whether family-administered screening, with targeted messages improves care practices known to mitigate LBWt risks. Participants: pregnant women participating in a parent trial in rural Nepal. Women were given a 6.9cm card to assess whether the baby’s foot is small; if so, to call number on the card for advice. Follow-up visits were made over 2 weeks following the birth, assessing for: reported skin-to-skin thermal care, and care-seeking outside the home; restricting to low birthweight (using 2 cutoffs: 2,500g and 2,000g). Randomization: 17 clusters intervention, 17 control. The study also documented steps along the presumed causal chain from intervention through behavioral impact.Results: 2,022 into intervention, 2,432 into control. Intervention arm: 519 with birthweight <2,500g (vs. 663 among controls), of which 503 were available for analysis (vs. 649 among controls). No significant difference on care-seeking; for those <2,500g RR 1.13 (95%CI: 0.97-1.131). More of those in the intervention arm reported skin-to-skin thermal care than among controls; for those <2,500g RR 2.50 (95%CI: 2.01-3.1). Process measures suggest this apparent effect cannot be attributed to the intervention; the card performed poorly as a proxy for LBWt, misclassifying 84.5% of those <2,000 as normal.Conclusions: Although the trial found an apparent effect on one key behavioral outcome, this cannot be attributed to the intervention; most likely it was a result of pure chance. Other approaches are needed for identifying at-risk babies in such settings, and targeting them for appropriate care messaging.Trial registration : clinicaltrials.gov identifier: NCT02802332, registered 16 June 2016, https://clinicaltrials.gov/ct2/show/NCT02802332

Background: Most newborn deaths occur among those of low birthweight (LBWt), due to prematurity &/or impaired fetal growth. Simple practices can substantially mitigate this risk. In low-income country settings where many births occur at home, strategies are needed that empower mothers to determine if their babies are higher risk and take measures to reduce risk. Earlier studies suggest that foot-length may be a good proxy for birthweight. An earlier Nepal study found a 6.9cm cut-off performed relatively well, differentiating normal from low birthweight.Methods: Community-based, cluster-randomized controlled trial. Objective: to determine whether family-administered screening, associated with targeted messages improves care practices known to mitigate LBWt-associated risks. Participants: women participating in a parent trial in rural Nepal, recruited late in pregnancy. Women were given a 6.9cm card to assess whether the baby’s foot is small; if so, to call a number on the card for advice. Follow-up visits were made over the 2 weeks following the birth, assessing for 2 behavioral outcomes: reported skin-to-skin thermal care, and care-seeking outside the home; assessed restricting to low birthweight (using 2 cutoffs: 2,500g and 2,000g). Randomization: 17 clusters intervention, 17 control.The study also documented performance along the presumed causal chain from intervention through behavioral impact.Results: 2,022 intervention, 2,432 control.

No significant difference found on care-seeking; for those <2,500g RR 1.13 (95%CI: 0.97-1.131). A higher proportion of those in the intervention arm reported skin-to-skin thermal care than among controls; for those <2,500g RR 2.50 (95%CI: 2.01-3.1).
