Before 20 weeks it is not viable (miscarriage);after 37 weeks,it can be considered term.Although these terms are used interchangeably,they have different meanings: preterm birth describes the length of gestation (before 37 weeks)regardless of weight;low birth weight describes weight only (2500 g or less)at the time of birth,whenever it occurs.Low birth weight is anything below 2500 g,or about 5.5 pounds.In 2006,the preterm birth rate in the United States was 12.8%;however,the rate is increasing in frequency.
