Abstract
Background: Understanding the effect of biological factors on birth weight of new-borns has public health importance because these indicators are associated with infant health and survival and influence development and health in later life. Aim: The study was undertaken to determine the birth weight and gestational age characteristics in south Indian babies and correlated to biological factors. Settings and design: A retrospective study of consecutive singleton live births, who delivered in the hospital in a metropolitan city of Bangalore, South India. Materials and Methods: A cohort of singleton live births, born from January 2015 to May 2017 were analysed to determine the mean birth weight and gestation and influence of various biological factors such as gender of baby, birth order, mother’s age, obstetric complication such as PIH and Diabetes etc. Results: Among a total of 2789 singleton live births, the mean birth weight was 2873.73 ± 498.6 g, mean gestation was 38.2 ± 2 weeks and Low Birth Weight (LBW) <2500 g was 19.1%. The Term, male, later births, older mothers above 30 years and pregnancy of Pregnancy Induced Hypertension (PIH) and diabetes were associated with statistically significant higher birth weight P=0.001, P=0.002, P=0.0001, P=0.001, P=0.0006 and P=0.0001, respectively.Conclusion: The mean birth weight and gestation for singleton live births in South India were determined, as well as the statistically significant impact of various biological criteria.
Highlights
Birth weight is one of the most important factors that predict the survival, future development and growth pattern of a new-born baby [1,2,3,4,5]
The present study was undertaken in a Speciality hospital in Bangalore, South India to determine the average birth weight and gestation as well the positive correlation of biological factors including complications of pregnancy such as Pregnancy Induced Hypertension (PIH) and Diabetes
Among the 2789 singleton live births included in the study, birth weight was missing for 2.9% (n=81), gestation was missing for 8.9% (n=251), gender was missing for 3.7% (n=105), birth order was missing for 4.1% (n=116) and mother’s age was missing for 7.3% (n=206)
Summary
Birth weight is one of the most important factors that predict the survival, future development and growth pattern of a new-born baby [1,2,3,4,5]. Birth weight is mainly influenced by duration of gestation but other biological factors such as gender, birth order, mother’s age, obstetric complications etc. The present study was undertaken in a Speciality hospital in Bangalore, South India to determine the average birth weight and gestation as well the positive correlation of biological factors including complications of pregnancy such as PIH and Diabetes. Understanding the effect of biological factors on birth weight of new-borns has public health importance because these indicators are associated with infant health and survival and influence development and health in later life
