Mothers with one or more risk factors for LBW were excluded. The charts that doctors use when assessing a baby's birth weight should take into account the mother's ethnicity, to better predict health problems after birth, a new study from Canada suggests. A value greater than 50 percent means a baby is above average. 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 . less than 1200 grams; or.

Birth Weight and Gestational Age Charts for British Columbia Populations 9 EXECUTIVE SUMMARY This report is the culmination of a project that began with the publication of a birth weight chart in the 1989 Vital Statistics Annual Report followed by a comprehensive report of birth weight and gestational age statistics, including mortality, in 1993. Historically, before accurate measurement of gestational age, birth-weight was the preferred measure.
