Parity related changes in obesity and some antioxidant vitamins in non-pregnant women of South-Eastern Nigeria.

BACKGROUND: The delivery of many children at short interval is associated with micronutrient depletion and weight gain. However, the relationship between the levels of the micronutrients and the body weight is yet to be ascertained. OBJECTIVES: To determine the relationship between parity, body weight and some antioxidant vitamins in non-pregnant Nigerian women. PATIENTS AND METHODS: Randomly recruited 200 non-pregnant women, comprising 82 primiparous and 118 multiparous women completed the study. Their age, parity, mid-arm circumference (MAC), waist circumference (WC), weight, height and body mass index (BMI) were determined. The serum levels of vitamins A, C and E were assayed using standard methods. Results : The mean BMI, WC and MAC of the multiparous subjects (parity = 3.0 ± 0.58) were significantly higher than that of the primiparous subjects (parity = 1), (P < 0.05, P < 0.01 and P < 0.01 respectively). Furthermore, there were statistically significant decrease in the vitamin A, vitamin C and vitamin E in multiparous compared with the primiparous women (P < 0.005, P < 0.05 and P < 0.005), respectively. CONCLUSION: Multiparty enhances weight gain, but depletes antioxidant vitamin micronutrients in non-pregnant Nigerian women.

Reduced maternal selenium levels in pregnant and lactating Nigerian women: should routine selenium supplementation be advocated?

BACKGROUND: Deficiencies in micronutrients are common in our environment, leading to indiscriminate replacement strategies. Selenium is an antioxidant micronutrient that may undergo depletion during pregnancy and lactation. Regrettably, information in this matter is scanty in Nigeria. OBJECTIVES: To determine maternal selenium concentration during pregnancy and lactation. METHODS: This was a cross-sectional research involving 120 pregnant women, 40 in each trimester. They were attending antenatal clinic of one tertiary and two secondary health care facilities in Enugu, Southeastern Nigeria. Control subjects constitute age, parity and socioeconomic matched 35 apparently healthy, non pregnant women. Serum selenium concentration was measured during pregnancy and postpartum. Breast milk selenium concentration was also determined by Atomic Absorption Spectrophotometer (AAS). RESULTS: The mean serum selenium levels were significantly decreased (P < 0.0001) in pregnancy when compared with non-pregnant control subjects; also as pregnancy progressed. However, there was a non significant increase immediately after birth. In the breast milk, selenium concentration significantly decreased (P < 0.0001) as lactation progressed. CONCLUSION: The observed significant decreases in the levels of selenium during pregnancy and breast milk may leave the mothers and their neonates at risk and, therefore, may necessitate maternal supplementation. Dietary intervention such as food diversification and bio-fortification is recommended to improve dietary selenium intakes in pregnant and lactating mothers, and infants in this region.

Plasma Concentration of Ascorbic Acid and Some Hematological Parameters in Tobacco Snuffers Among the Igbos of Southeastern Nigeria

Tobacco snuffing; like cigarette smoking; is known to be a common habit among the adults of Igbo communities in Nigeria. In view of the various pharmacological actions of nicotine and other additive constituents of tobacco snuff; there is growing concern that ascorbic acid; which is a vital antioxidant; and blood cell production or morphology may be affected. Objective: To investigate the possible effects of prolonged use of tobacco snuff on plasma ascorbic acid concentrations and some hematological parameters. Materials and Methods: Fifty adults of Igbo extraction (35 males and 15 females) residents in and around Enugu metropolis; who have been snuffing tobacco for 6 years and above; were recruited for the study; after they gave informed consent. Also; 50 apparently healthy; age-matched persons (25 males; 25 females); who do not smoke or take tobacco snuff; served as controls. Spectrophotometric method was adopted for ascorbic acid determination while hematological profiles were assessed by Bain method. Results: The results showed no significant difference in the measured parameters relative to the controls AA (P=0.08); Hb (P=0.19); PCV (P=0.10); RC (P=0.06); PC (P=0.20); WBC (P=0.09). Conclusion: The results of the study suggest that tobacco snuff inhalation may not adversely affect plasma ascorbic acid concentration and hematological parameters in adult humans. The study; however; has not concluded that tobacco snuffing is totally wholesome

Copper and selenium status of healthy pregnant women in Enugu, southeastern Nigeria.

BACKGROUND: Copper and selenium are important trace elements in man. They function as antioxidants and play roles in oxido-reductase reactions. Several imported multivitamin preparations are given to our women during pregnancy and lactation to correct possible deficiencies. OBJECTIVE: The aim of the study is to determine the serum level of these micronutrients (selenium and copper) in a cross section of pregnant women in Enugu, southeastern Nigeria. MATERIALS AND METHODS: A cross section of 130 healthy pregnant women at different trimesters of pregnancy and 30 non-pregnant controls were selected from two health facilities in Enugu, southeastern Nigeria. Serum from the samples collected was assayed for copper and selenium using atomic absorption spectrophotometer. RESULTS: The mean copper level increased (P = 0.018), while the selenium level decreased (P < 0.0001) as pregnancy advanced. CONCLUSION: High copper levels indicate that supplementation should not be undertaken during normal pregnancy. Dietary intake should be modified to ensure optimal selenium levels during pregnancy.

Zinc Concentration during Pregnancy and Lactation in Enugu; South-East Nigeria

Background: There is no doubt that micronutrient deficiency is common in our environment. Replacements have thus been instituted without adequate information on specific and peculiar micronutrient needs of our people. Zinc is an essential micronutrient which is prone to maternal depletion during pregnancy and lactation. Unfortunately; studies in that regard in Nigeria has received diminutive interest. Objectives: To determine zinc concentration during pregnancy and lactation. Methods: This is a cohort study involving one hundred and twenty (120) pregnant women attending the antenatal clinic of one tertiary and two secondary health care institutions in Enugu. Thirty-five (35) apparently healthy; non pregnant women were used as control subjects. Atomic Absorption Spectrophotometer (AAS) was used to determine the zinc levels in the serum of the mothers during pregnancy; postpartum and in the breast milk. Results: Results showed that mean serum zinc levels were significantly decreased (P 0.0001) in pregnancy when compared with non-pregnant control subjects. The levels decreased as gestation progressed; with the lowest concentration of serum zinc obtained during the third trimester. It was also observed that serum zinc levels which decreased in pregnancy; increased non- significantly (P

Assessment of Iron Content of Breast Milk in Preterm and Term Mothers in Enugu Urban

Background: It is commonly assumed that preterm babies are malnourished and this has led to all forms of micronutrient supplementation including iron. Objective:The aim of the study is to compare the iron content in breast milk of mothers who had preterm and term babies.Methods:Ninety six (96) lactating mothers who delivered their babies at term and 68 lactating mothers who had preterm deliveries were recruited for the study. The mothers were attending the postnatal clinic of one secondary and two tertiary healthcare facilities in Enugu. Breast milk iron concentration was determined by Atomic Absorption Spectrophotometer.Results:The differences in the mean values for the iron concentrations in preterm and term breast milk were statistically significant (39.06±10.78 versus 32.79±14.17 µmol/L, P =0.02). In both groups, the breast milk iron concentration gradually decreased as lactation progressed. (P <0.0001).Conclusion:The iron content of breast milk from mothers who had preterm babies is higher when compared to mothers who had term babies. It may thus be needless to introduce exogenous iron during lactation

Oxidative Stress and Glycaemic Control in Type 2 Diabetic Patients in Enugu; South-East Nigeria

Background: There is growing evidence that excess generation of highly reactive free radicals; largely due to hyperglycaemia causes oxidative stress; which further exacerbates the development and progression of type 2 diabetes and its complications. Objectives: In this study; the level of oxidative stress was compared with glycaemic control in type 2 diabetic patients. Method: Fifty confirmed type 2 diabetic patients; aged between 25 and 70 years were used for the study. 20 patients with good glycaemic control served as positive control while 20 apparently healthy non-diabetic age-matched individuals served as negative control. The FBS; MDA and HbA1c were determined in fasting blood samples using standard methods. Results: Patients with poor glycaemic control had significantly raised MDA and HbA1c (P =0.0001) when compared with non diabetics However; those with good glycaemic control only had a significant increase in the MDA when compared to non diabetic. (P =0.0001).).The MDA level when compared to fasting blood sugar (FBS) and glycated haemoglobin (HbA1c) showed a positive correlation.( r= 0.77; P = 0.0001 and r=0.69; P = 0.0001 respectively) Conclusion: This study showed that both glycaemic control and lipid peroxidation are factors to be monitored or evaluated in the management of type2 diabetics to avoid the development of diabetic complications

Assessment of body mass index and blood pressure among university students in, Enugu, South East, Nigeria.

BACKGROUND: Body Mass Index (BMI) has been described as a significant predictor of Blood Pressure (B.P) but few studies have demonstrated this association in our environment. The study aims to determine the pattern of relationship between BMI and blood pressure in our environment. METHODOLOGY: Two thousand and ninety six (2096) students in two Universities located in Enugu, South East Nigeria completed the study. The blood pressure, weight and height were measured. Body mass index was calculated as weight in Kilograms divided by height in meters square (kg/m2). RESULTS: More females than males were underweight (9.4% versus 4.7%). More males than females were overweight (8% versus 4%).Obesity occurred more in males than females (7% versus 0.9%). Blood pressure parameters increased significantly with BMI (p < 0.0001) with higher values in males than in females; (the mean systolic blood pressure 124.88 +/- 10.97 mmHg versus 114.93 +/- 6.82 mmHg, P < 0.0001; the mean diastolic blood pressure was 80.1 +/- 7.2 mmHg versus 73.36 +/- 6.82 mmHg, p = 0.035 and the mean arterial Pressure (MAP) 95.02 +/- 7.78 mmHg versus 87.2 +/- 9.58 mmHg, p < 0.0001). CONCLUSION: A significant relationship between BMI and Blood pressure was demonstrated among university students in South East Nigeria.

Atherogenic index of plasma as useful predictor of cardiovascular risk among postmenopausal women in Enugu, Nigeria.

BACKGROUND: Menopausal health in our environment has received little attention. As an independent risk factor for dyslipidaemia, the degree and pattern of derangement, though difficult to assess may adversely affect the cardiovascular health of our women. OBJECTIVES: To estimate the serum lipid profile and the atherogenic index of plasma in normal post menopausal women. METHODS: This is a cross sectional study involving 80 apparently healthy women voluntarily recruited from staff of the University of Nigeria and the Teaching Hospital (UNTH) located in Enugu. They include 50 postmenopausal subjects aged between 50 and 70 years and 30 premenopausal controls aged between 25 and 49 years. Total cholesterol (TC), and the various subfractions; high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), low density lipoprotein cholesterol (LDL-C) and triglycerides (TG) were determined. Atherogenic index of plasma (AIP); log (TG/HDL-C) was calculated. RESULTS: There were statistically significant increases (P< 0.0001) in TC, TG, LDL-C, VLDL-C and AIP but a statistically significant decrease (P<0.0001) in HDL-C in postmenopausal women when compared with the premenopausal subjects. Except HDL-C that showed insignificant reduction, there were statistically significant derangement of other lipid subfractions as the duration of menopause increased. CONCLUSION: Menopause, no doubt alters lipid profile. A triglyceride based index (AIP) can significantly add value when assessing the risk of developing atherosclerosis in Nigeria.

Assessment of Body Mass Index and Blood Pressure among University Students in; Enugu; South East; Nigeria

The effect of potassium bromate on some haematological parameters of Wistar rats.

Potassium bromate used widely in foods has been associated with various complications in humans. However there is paucity of literature on adverse effects on haematological parameters. Thus we decided to carry out an experimental study to determine the effects of potassium bromate on some blood indices using Wistar rats. Twenty (20) male Wistar rats aged 2-3 months obtained from the department of Veterinary Medicine, University of Nigeria Nsukka were acclimatized for two weeks. They were divided into five groups and fed with graded doses of potassium bromate solution for six weeks. One of the groups served as the control. Pre and post administration blood samples were collected and analyzed the same day using standard methods. The results revealed significant [P<0.05] decrease in the platelet count when compared with the controls. There were no statistically significant differences in the mean cell haemoglobin concentration, haematocrit, and total leukocyte counts between the test and control rats. Potassium bromate is injurious to health if consumed continuously and in high quantity. It has been shown to reduce platelet count in rats, and thus may cause thrombocytopenia in humans. It is therefore imperative to take adequate measures to eliminate the use of potassium bromate in the preparation of food products.

Evaluation of serum uric acid levels in normal pregnant Nigerian women.

BACKGROUND: Hypertensive disorders in pregnancy are common in our environment. The aetiology is unknown and the prognostic indicators of the severity of maternal and fetal complications are variable. The level of uric acid, which is one of the prognostic indicators, is altered in normal pregnancy and as pregnancy advances. Base line values are thus extremely important to enable reasonable prognostic assessment in hypertensive pregnancies. OBJECTIVES: To determine levels of serum uric acid during normal pregnancy in University of Nigeria Teaching Hospital (UNTH) Enugu. STUDY DESIGN: settings and methods: Sixty- five pregnant and 65 non-pregnant women with age range 20-38 years were recruited. The pregnant women were in their second and third trimesters, attending antenatal clinic at the University of Nigeria Teaching Hospital Enugu. Serum levels of uric acid were determined for the entire subjects. RESULTS: The serum uric acid levels were significantly lower in the pregnant women than in controls (P < 0.001). 0.15 +/- 0.03 mmol/L in the second trimester, 0.14 +/- 0.02 mmol/L in the third trimester and 0.29 +/- 0.04 mmoL for control. CONCLUSION: The low levels in pregnancy and as pregnancy progresses should be taken into consideration when monitoring hypertensive disorders in pregnancy using serum uric acid. Thus levels that are within normal for non pregnant population may indeed be an indication for intervention in pregnancies complicated by preeclampsia.
