Background: Birth weight acts as a crucial sensitive and reliable tool to prevent infant and child morbidity and mortality. There has been a considerable interest in recent years for using simple anthropometric measures as an alternative to birth weight. Objective of the study is to determine the cut off values of the anthropometric measurements and to assess the accuracy of the anthropometric surrogates to identify low birth weight babiesMethods: This is a cross sectional study conducted for a period of one year from 1st Dec 2011 to 31st Nov 2012 at Christian fellowship hospital, Oddanchatram, Dindigal, Tamilnadu. Study population included all the live newborns of term gestation at the hospital. A total of 500 newborns were included in the study during the period. Birth weight of the newborn was measured using spring scale to the nearest 25 grams. Head circumference, Chest circumference, Mid Upper Arm Circumference, Foot Length, Thigh circumference, Calf circumference, Crown-hell length were measured using proper guidelines to the nearest 0.1 cm.Results: In the present study, low birth weight was present in 262 (52.4%) of the newborns. Thigh circumference with cut off value of 15 cm had higher sensitivity and specificity of 97.5% and 80.9% respectively. It was followed by Mid upper arm circumference with cut off value of 10 cm, sensitivity of 81.5% and specificity of 93.9%. Thigh circumference and mid upper arm circumference had high area under curve of 0.949 and 0.855 respectively. All the anthropometric measurements were statistically significant at 5% level of significance.Conclusions: Thigh circumference with a cut off of 15 cm, followed by mid upper arm circumference of 10 cm were the better surrogate anthropometric measurements with better sensitivity, specificity to identify low birth weight babies.
Introduction: Low birth weight is seen most commonly in developing countries. In India majority of births are conducted at home by the Traditional Birth Attendants (TBA) or relatives, where the estimation of birth weight is not done because of lack of weighing machines. Therefore, an early identification and prompt referral of LBW newborns is vital in preventing neonatal deaths. Objective: To determine the magnitude of low birth weight babies and to correlate birth weight and other anthropometric measurements. Methodology: This is a cross sectional study done at Christian fellowship hospital, Oddanchatram, Dindigal, Tamilnadu from 1 st Dec 2011 to 31 st Nov 2012. 500 newborns were examined within 24 hours of their birth in this hospital during this period. Antenatal history and anthropometric measurements were recorded. Results: The male newborn (57.2%) were more than of female (42.8%). The magnitude of the low birth weight was 262 (52.4%). It was observed that correlation coefficients of all the parameters are positive and are statistically significant (p < 0.001). Maximum and minimum positive correlation was observed in case of thigh circumference (r = 0.776) and Foot length (r = 0.460) respectively.
Objective:To study the incidence and risk factors predisposing to retinopathy of prematurity (ROP) in Bapuji child Health Institute NICU. Design: Prospective cohort observational study. Setting: Infants admitted to a neonatal intensive care unit of Bapuji child Health Institute NICU in a period of two years. Methods: Preterm infants with birth weight < 1500g and gestation <34 weeks were screened for ROP at 4 weeks after birth or 31-33 weeks post conceptional age, whichever was later. Infants with birth weight >1500g and gestation >34weeks were screened only if they had additional risk factors. Those found to have high risk ROP had laser photocoagulation. Results: The incidence of ROP in the 200 infants who were screened was 13.5%. No ROP was found in infants weighing >2000g or with a gestational age more than 36weeks. Risk factors predisposing to ROP were oxygen therapy (P=0.04), apnea [p=0.001], ventilation [0.001], anemia [0.001], blood and blood product transfusion [0.001 ]. Conclusion: One third of the infants with ROP needed laser photo coagulation, the outcome of which was good. Risk factors predisposing to ROP were oxygen therapy, apnea, ventilation, blood transfusion, exchange transfusion.
