Antenatal haemoglobin profile at the Port Moresby General Hospital.
From 1 November 1995 to 10 April 1996, 1001 consecutive mothers who had attended the Port Moresby General Hospital (PMGH) antenatal clinic and were delivered in the Maternity Unit of the PMGH were surveyed for their antenatal haemoglobin (Hb) levels. One or more Hb results had been noted in the antenatal records of 997 subjects. The mean of the first Hb level for this sample was 10.6 +/- 1.72 g/dl. The first Hb level was below 10.0 g/dl in 33% of the 997 subjects. The dates were reliable in 777 subjects. The mean first Hb for this group was the same as for the total sample. A subgroup of 449 subjects with reliable dates and first Hb measurement at < or = 26 weeks gestation had a first Hb mean of 10.9 +/- 1.78 g/dl. Among those with reliable dates, 569 had two or more Hb measurements, the last being at > or = 34 weeks. In this subgroup, the mean of the last Hb was 11.1 +/- 1.60 g/dl. The first Hb was measured at < or = 26 weeks in 352 subjects in this subgroup. The means for the first and last Hb levels for this subset were 10.9 +/- 1.78 and 11.1 +/- 1.57 g/dl, respectively; the paired t test did not show any difference between the first and last Hb levels. For subjects in the total sample who had two or more Hb measurements, the mean for the lowest Hb level was 10.0 +/- 1.54; 45% had levels below 10.0 g/dl at some time during the pregnancy.
