PARAMETERS FOR DIETARY REFERENCE INTAKES

Life Stage Categories

The life stage categories described below were chosen with all the nutrients to be reviewed in mind, rather than only those included in this report. Additional subdivisions within these groups may be added in later reports. For example, pregnancy may be subdivided into two or more periods to accommodate women's changing needs for certain nutrients. Differences will be indicated by gender when warranted by the data.

Infancy

Infancy covers the period from birth through 12 months of age and is divided into two 6-month intervals. The first 6-month interval was not subdivided further because intake is relatively constant during this time. That is, as infants grow, they ingest more food; however, on a body weight basis their intake remains the same.
