The average birth weight in babies of European descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.5 kilograms (5.5 and 9.9 lb). The overall neonatal mortality rates for whites, Hispanics, and blacks were 3.24, 3.45, and 8.16 neonatal deaths per 1000 live births, and the proportion of births <28 weeks was 0.35%, 0.45%, and 1 .

In 100.04B , gestational age is the infant's age based on the date of conception as recorded in the medical record. Introduction. Frequency line graphs of the birth weight distribution. All low birth weight (LBW) and very low birth weight (VLBW) infants and children (up to 2 years of age) who have reached the equivalent age of 40 weeks gestation, shall be assessed for growth using the 2000 CDC Birth to 36 Months Growth Charts . SGA babies may be proportionately small (equally small all over) or they may be of normal length and size but have lower weight and body mass.

Historically, before accurate measurement of gestational age, birth-weight was the preferred measure. A majority of LBW infants are preterm infants, but in some cases, they are Small for Gestational Age. Abstract Background: This study was taken up to identify the main types of low birth weight(LBW) for the development of weight for gestational age charts relevant to thecountry/regional level for the formulation of preventive strategies.Materials and Methods: A sample of mothers registered by Public Health Midwives(PHMs) from two Medical Officers of Health (MOH) areas in . 30.
