The North American site in the INTERGROWTH ‐21 st Project was N orth S eattle, W ashington S tate, USA . The majority of the data were collected from within S eattle C ity, which has approximately 12 300 births per year. The sample for the N ewborn C ross‐ S ectional S tudy (NCSS) was drawn from two hospitals ( S wedish M edical C enter and the U niversity of W ashington) covering almost 80% of deliveries within the target population. The F etal G rowth L ongitudinal S tudy (FGLS) sample was recruited from several antenatal clinics serving the U niversity of W ashington M edical C enter and P rovidence E verett M edical C enter. Special activities to encourage participation and raise awareness of the studies included furnishing the recruitment sites with fliers designed by the P roject C oordinating U nit, and presenting the studies to clinical staff to encourage providers to refer appropriate patients. One of the major challenges at this site was the low recruitment rate in the early phase of the FGLS because of the high rates of smoking, maternal age >35 years and body mass index >30 years. This was remedied by the inclusion of other ancillary clinics, as well as increased advertising among the general public.
