Introduction: Women are considered to be vulnerable with regards to immunothrombotic conditions. Exploring this bidirectional susceptibility across the different female reproductive phases is important for effective maternal healthcare delivery. This study assessed selected indicators of immunothrombosis between premenopausal and postmenopausal women. Methods: Equal numbers of premenopausal and postmenopausal women totaling one hundred were recruited for this comparative study. Blood sample was collected from each participant into appropriate sample bottles. Blood cell counts were carried out by haemocytometry and microscopic blood film reading. Standard manual methods were also employed for prothrombin time, activated partial thromboplastin time and relative plasma viscosity tests, while blood cell ratios were calculated. Results are expressed as Mean ±SD following student t-test analysis of data on SPSS version 22.0. Statistical significance was drawn at a p≤ 0.05. Results: The eosinophils count (0.42±0.31x109/l), monocyte count (0.05±0.05x109/l) and platelets count (150.04±46.88x109/l) were significantly higher in premenopausal women than postmenopausal women (0.29±0.27x109/l, 0.03±0.03x109/l and 132.62±38.37x109/l respectively), while a significantly higher value was observed in the relative plasma viscosity of postmenopausal women (1.74±0.17mPa/s) than the premenopausal women (1.59±0.10mPa/s). The two derived indicators of inflammation (NLR) and thrombosis (PLR) correlated positively in both premenopausal (r=0.397, p=0.004) and postmenopausal (r=0.293, p=0.039) women. Conclusion: Immune and thrombotic parameters are largely comparable in apparently healthy adult females irrespective of their reproductive phase. However, eosinophil, monocyte and platelet counts were observed to be significantly higher in premenopausal women compared to postmenopausal women.

Introduction: Maternal healthcare takes into consideration the immediate state of an individual woman with regards to health status and subsequent management. Anaemia is a common maternal health challenge that is affected by hormonal shifts in women. Thus, this study focused on prevalence of anaemia and iron requirement across women of premenopausal and postmenopausal phases. Methods: This study enrolled apparently healthy 100 females with equal numbers of premenopausal and postmenopausal subjects. Blood sample was appropriately obtained from each subject for assessment of red cell and iron parameters. Microhaematocrit and cyanmethaemoglobin methods were employed for the measurement of packed cell volume and haemoglobin concentration respectively, while the iron parameters were assayed by colorimetric methods. Transferrin saturation was mathematically derived. Results are expressed as Frequencies and Mean ±SD, while student t-test was used for analysis of data on SPSS version 22.0. Statistical significance was drawn at a p≤ 0.05. Results: Postmenopausal women had significantly higher values of packed cell volume (0.38 ± 0.03 l/l), haemoglobin concentration (125.50 ± 9.30 g/l), serum iron (23.17 ± 0.93 µmol/l) and transferrin saturation (36.88 ± 2.00 %) than the premenopausal women (0.37 ± 0.02 l/l, 121.44 ± 7.83 g/l, 15.53 ± 2.60 µmol/l and 20.70 ± 3.60 % respectively) while the premenopausal women had significantly higher values in total iron binding capacity (75.24 ± 3.32 µmol/l) than the postmenopausal women (62.97 ± 1.88 µmol/l. Whereas 30% of the premenopausal women were anaemic and 10% had low transferrin saturation, anaemia in postmenopausal women occurred at a prevalence of 18% and the indicators of iron need were adequate. Conclusion: This study has shown that among apparently healthy individuals, prevalence of anaemia and iron requirement are lower in postmenopausal women than premenopausal women.
