1 in every 7 pregnancies have MSAF and, of these cases, approximately 5% of these infants develop<unk> . MSAF is observed 23-52% in pregnancies at 42 weeks therefore, the frequency of<unk>  increases as the length of gestation increases, such that the prevalence is greatest in post-term pregnancies. Conversely, preterm births are not frequently associated with MSAF (only approximately 5% in total contain MSAF). The rate of<unk>  declines in populations where labour is induced in women that have pregnancies exceeding 41 weeks. There are many suspected pre-disposing factors that are thought to increase the risk of<unk> . For example, the risk of MSAF is higher in African American, African and Pacific Islander mothers, compared to mothers from other ethnic groups.
