Review Measure

Essential Measures are only those items that are critical to the collection of the Measure or are necessary for the interpretation of results. Essential Measures are integral to the Measure. Without such information the data collected would be incomplete and/or misleading.
An additional PhenX Measure that the user may find helpful based on the selection of a particular PhenX Measure. Related PhenX Measures can include additional Measures that are needed to calculate a Derived Variable (e.g., Weight and Height are needed to calculate BMI), Measures that are commonly used in presentations and publications to present the value of the chosen Measures (e.g., Height and Weight by Race and Ethnicity), Measures that are conceptually related to the chosen Measure (e.g., Current Educational Attainment is conceptually related to Annual Family Income and Arm Span is conceptually related to Height), Measures that are physiologically and/or biologically related to the chosen Measure (e.g., Stroke and Heart Disease). Related PhenX Measures are suggestions only.
The Collections are an alternative to the research domains for browsing the PhenX Measures. Measures that are related by a specific topic are grouped together.

Measure: Birth Weight   #020200


Birth weight (measured, recalled, or vital records/chart abstraction) is the weight of the infant in grams or pounds and ounces at birth. Birth weight is directly related to gestational age.


Birth weight is associated not only with the health status of the infant/child, but has also been linked to later-life conditions such as obesity, hypertension, kidney disease, diabetes, and other chronic conditions. Birth weight is influenced by genetics, maternal health, prenatal health, pregnancy complications, environmental factors, multiple-gestation births, and other factors. Low birth (LBW) poses significant health risks. Birth weights, collected as part of a comprehensive reproductive history, may also be linked to later-life conditions in the mother. For example, large infant size may indicate undiagnosed gestational diabetes and an increased risk for adult-onset diabetes in the mother.
