Assessing the prevalence of anaemia, iron deficiency and iron deficiency anaemia among non-pregnant and pregnant women is essential for evidence-based intervention programs. The purpose of this prospective outpatient and community-based cross-sectional study was to assess the prevalence of those conditions among pregnant women resident in the National Capital District (NCD) and attending the Outpatient Antenatal Clinic in Port Moresby General Hospital. Blood samples were collected from 50 non-pregnant and 157 pregnant women who gave consent. HemoCue was used to measure haemoglobin; the serum ferritin, soluble transferrin receptor (sTfR) and C-reactive protein were measured by specialized 96-well enzyme-linked immuno-sorbent assay (ELISA) kits. The ‘sTfR-F index’ was calculated. Mild to moderate anaemia, low serum ferritin and elevated serum sTfR were found in 28% of the non-pregnant women; the sTfR-F index showed that 16% of them had iron deficiency anaemia. Among the pregnant women, 60% had mild to severe anaemia indicating severe public health significance; 48% had low serum ferritin and 38% had elevated serum sTfR; the sTfR-F index showed that 38% of them had iron deficiency anaemia. Mild to severe anaemia was present in 47%, 71% and 62% of the pregnant women in the first, second and third trimesters respectively, while iron deficiency anaemia was present in 20%, 53% and 48% of the pregnant women in the first, second and third trimesters respectively. The sTfR-F index showed that iron deficiency anaemia was present in 36% of primigravida and 40% of multigravida. Social mobilization, intensive and focused education, aggressive awareness campaigns, including all relevant target groups and policy makers, are required to effectively address this major public health issue.

This cross-sectional study assessed the zinc status of non-pregnant and pregnant women resident in the National Capital District (NCD), Papua New Guinea (PNG). Non-fasting morning blood samples were collected by venipuncture from consented women. Flame atomic absorption spectrometry was used to measure the serum zinc concentration in 27 non-pregnant and 100 pregnant women. C-reactive protein (CRP) in serum was measured by enzyme immunoassay and used to interpret the serum Zn data. For all the non-pregnant women, the median serum zinc concentration was 42.7 mug/dl with an interquartile range (IQR) of 27.6 to 91.2 mug/dl. Zinc deficiency was prevalent among 59% in this group of women. For those with normal CRP the median and IQR serum zinc concentrations were 48.9 mug/dl and 30.2 to 98.7 mug/dl, respectively. The median and IQR for all the pregnant women were 63.8 mug/dl and 40.9 to 93.2 mug/dl, respectively. Prevalence of zinc deficiency was 42% using the cut-off point of 56.0 mug/dl. Of the 100 pregnant women, 16 (16%) were in the first trimester, 51 (51%) in the second trimester and 33 (33%) in the third trimester. The median serum zinc concentrations of pregnant women in the first, second and third trimesters were 87.0 mug/dl, 61.6 mug/dl and 60.8 mug/dl, respectively. Using gestational period-specific cut-off points, zinc deficiency was prevalent among 31%, 39% and 36% of the pregnant women in the first, second and third trimesters, respectively. Our results clearly indicate suboptimal zinc status among non-pregnant and pregnant women in the NCD. According to the International Zinc Nutrition Consultative Group (IZiNCG) criteria, this should be considered as a public health problem among these groups of women in the NCD. To effectively address the issue, social mobilization, intensive education and awareness campaigns, with all relevant target groups and policy makers, are urgently required.
