Geophagia, nutrition and health of women with pregnancy-induced hypertension

Background: Calcium is a major nutrient implicated in pregnancy-induced hypertension (PIH). Aside dietary sources, geophagia has been reported to provide calcium needed to prevent PIH. These soils are shown to contain significant amount of heavy metals which have been associated with hypertension. Objective: The aim of this study was to determine the relationship between geophagia and PIH, assess the dietary intakes and health of participants. Methods: This study was a case-control involving 30 women with PIH and 70 normotensive pregnant women. Results: Geophagia was not significantly associated with PIH. Women with PIH practicing geophagia recorded significantly low levels of haemoglobin, calcium and ferritin. Hypertensives recorded impaired fasting blood glucose (5.77\ub11.71mmol/L, p=0.051), higher levels of urea (3.60\ub11.29 mmol/L, p=0.000) and creatinine (382.67\ub111.66 \ub5mol/L, p=0.000). Percentage intakes of macronutrients for normotensives were within the Adequate Macronutrient Distribution Range and PIH group recorded higher intakes of carbohydrate (72.75\ub116.16 %), lower protein (9.77\ub15.61 %) and fat (17.15\ub111.99%). Dietary calcium intakes in both groups were lower than recommended (< 1,000 mg/day). Conclusion: In this study, geophagia during pregnancy is not directly associated with PIH but is detrimental to maternal health. The pregnant women in this study had considerably low intakes of energy and nutrients. There is a need for measures to ensure adequate maternal nutrition for a positive health and pregnancy outcomes

Prediction of metabolic syndrome among postmenopausal Ghanaian women using obesity and atherogenic markers

Abstract Background Metabolic syndrome (MetS) is an important health problem which puts individuals at risk for cardiovascular diseases and type 2 diabetes as well as obesity-related cancers such as colon and renal cell in men, and endometrial and oesophageal in women. Objective This study was aimed at examining how obesity indicators and related determinants influence metabolic syndrome, and how the factors can be used to predict the syndrome and its cut-offs in postmenopausal Ghanaian women. Methods Two hundred and fifty (250) Ghanaian subjects were involved in the study with one hundred and forty-three (143) being premenopausal women and one hundred and seven (107) postmenopausal women. The influence of traditional metabolic risk factors including high blood pressure, dyslipidemia and glucose intolerance on obesity and atherogenic indices i.e. body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), Waist-to-thigh ratio (WTR), waist-to-height ratio (WHtR), high density lipoprotein cholesterol to total cholesterol ratio (HDL-C/TC), high density lipoprotein cholesterol to low density lipoprotein ratio (HDL-C/LDL-C) and triglyceride to high density lipoprotein cholesterol ratio (TG/HDL-C) were identified according to the Harmonization (H_MS) criterion. Results The predominant anthropometric marker that significantly influence metabolic risk factors among the pre- and postmenopausal women was waist-to-hip ratio (premenopausal: p- 0.004, 0.026 and 0.002 for systolic blood pressure (SBP), fasting blood glucose (FBG) and HDL-C; postmenopausal: p-0.012, 0.048, 0.007 and 0.0061 for diastolic blood pressure (DBP), FBG, triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) respectively). Using the receiver operating characteristic (ROC) analysis, the area under the curve for WC, WHR, TG/HDL-C and HDL-C/TC among postmenopausal women were estimated at 0.6, 0.6, 0.8 and 0.8 respectively. The appropriate cut-off values for WC, WHR, TG/HDL-C and HDL-C/TC that predicted the presence of metabolic syndrome were 80.5 cm, 0.84, 0.61 and 0.34 respectively. Conclusion The presence of metabolic syndrome among Ghanaian postmenopausal women can be predicted using WC, WHR, TG/HDL-C and HDL-C/TC.</p
