Conclusions
Patients with previous spontaneous preterm birth from 16 weeks onwards
are at high risk for recurrent preterm birth and should be considered
and treated as such with preventive measures. A short interpregnancy
interval of 0-3 months was associated with a significantly increased
risk for subsequent PTB and should be actively discouraged in these
patients.
