Simple anthropometric measurements to predict birth weight: A clinical study
Journal Title: Medpulse International Journal of Pediatrics - Year 2017, Vol 4, Issue 3
Abstract
Background: Of the approximately four million global neonatal deaths that occur annually, 98% occur in developing countries, where most newborns die at home while they are being cared by mothers, relatives, and traditional birth attendants. Aims and Objectives: To study Simple anthropometric measurements to predict birth weight. Methodology: After approval from institutional ethical committee this cross-sectional study carried out in the newborn’s of a tertiary health care center, the anthropometric measurements were taken within the first 24 hours of life. The anthropometry which studied were ; the body length and the foot length (FL), as well as circumferences of head (OFC), chest (ChC), thigh (ThC) and calf (CaC) were measured to the nearest 0.1 cm using a non-elastic, flexible measuring tape, while the MUAC was measured using the UNICEF tri-coloured flexible measuring tape. The statistical analysis done by regression analysis , Area undercurve , Cutt-off value Positive predictive value (PPV) and Negative predictive value (NPV) SPSS Software 19 version . Result: In our study we have found that The parameters like ChC, MUAC, CaC, ThC, OFC, FL, Length well corelated with Normal birth weight i.e. 0.51 (0.01), 0.48 (0.01), 0.54(0.001), 0.46 (0.00), 0.39 (0.001), 0.29 (0.001), 0.31 (0.001); and with LBW<2.5 kg was 0.71 (0.001), 0.67 (0.002), 0.65 (0.001), 0.61 (0.001), 0.52 (0.001), 0.50 (0.001), 0.49 (0.001) and not corelated with VLBW except FL -0.44 (0.02) respectively co-relation co-efficient and p-value. Cut-off value (cm), PPV % (95% CI), NPV % (95% CI) respectively for; ChC -≤ 28.92, 76.0 (66.2–81.23), 93.9 (90.1–94.6) , CaC - ≤9, 73.82 (67.3–79.7), 93.4 (91.3–95.2) , MUAC -≤9.67, 73.8 (65.0–79.6), 90.9 (88.7–92.7) , OFC -≤30.2, 65.2 (58.4–71.7), 90.1 (86.5–91.0) ; FL-≤7.5, 62.1 (53.1–72.2), 84.1 (80.42–88.2) ; ThC -≤14.20, 50.0 (45.01–58.2), 94.1 (91.1–96.0) ; Length-≤46.12, 42.3 (37.2–47.1), 92.2 (89.54–95.3). Conclusion: It can be concluded that In resource-poor settings , a large proportion of deliveries take place at home and birth-weight is most often not recorded. Therefore, there is a need to develop simple, inexpensive and practical methods to identify LBW newborns soon after birth
