Defining prematurity as applying to LBW infants of less than 37 weeks' gestation and classifying those LBW infants of greater than 37 weeks as having IUGR provides an improved means of analyzing different risk factors. 2. In accordance with the method of D'Angelo and Sokol, risk factors have been assigned to the various disease entities and social factors (8). 3. There is a suspicion in some disease entities, such as chronic hypertension, that prematurity is of equal frequency to IUGR, and in others, such as renal disease, that IUGR may not be increased at all, at least in term or near-term gestation. A reevaluation of the relationship of some disease entities to IUGR and prematurity is needed, probably in the sophisticated manner of Hoffman et al (15).

将早产定义为适用于妊娠小于37周的低体重婴儿，并将那些妊娠大于37周的低体重婴儿归类为患有宫内生长受限，这为分析不同风险因素提供了一种改进的方法。2. 根据D'Angelo和Sokol的方法，已将风险因素分配到各种疾病实体和社会因素中(8)。3. 在某些疾病实体中，如慢性高血压，有人怀疑早产与宫内生长受限的发生率相同；而在其他疾病实体中，如肾脏疾病，有人怀疑宫内生长受限可能根本没有增加，至少在足月或接近足月妊娠时是这样。可能需要以Hoffman等人(15)的精细方式重新评估一些疾病实体与宫内生长受限和早产之间的关系。
