Preterm or not--an evaluation of estimates of gestational age in a cohort of women from Rural Papua New Guinea.

ABSTRACT:

Background

Knowledge of accurate gestational age is required for comprehensive pregnancy care and is an essential component of research evaluating causes of preterm birth. In industrialised countries gestational age is determined with the help of fetal biometry in early pregnancy.

Methods
