Abstract Preterm birth is an important cause of neonatal morbidity and mortality. The incidence of pre-term birth in India is estimated to be 11-14% in 2004.In Safdarjung Hospital, 17.01% of all births were pre-term in the year 2009. However, only about 10-50% of women who present with signs and symptoms of pre-term labour actually deliver prematurely. It is important to identify which of these women are likely to deliver pre-term, so that appropriate management strategies can be directed towards that particular group. Therefore, there is an urgent need of developing markers to predict the likelihood of pre-term birth in women who present with threatened preterm labor. Cervical length and cervicovaginal âhCG have been evaluated alone, and together, to predict preterm delivery by very few studies in symptomatic women. The current study has been undertaken to evaluate whether a these factors alone, or in combination,will improve the predictability of preterm labour and hence decrease the unnecessary intervention.
