Author(s): Tesfaye Getachew Charkos* and Hunde Lemi
Background: Epidemiological studies examining the impacts of maternal age and body mass index on the birth weight of a newborn is still sparse. We aimed to investigate the relationship between maternal age and body mass index with birth.
Methods: This cross-sectional study identified females aged 15 to 49 years with complete and valid data on the maternal age, maternal body mass index, and birth weight of newborns from the Ethiopian demographic and health survey 2016. Linear regression and Generalized Additive Models (GAMs) were used in this study.
Results: A total of 2110 females were included, with the average of BW, LBW, and macrosomia were 3280 g, 1920 g, and 4880 g respectively. After adjusting all covariates, we found that a one-year increment of maternal age was associated with 6.375 g increases in the birth.. View More»
