Vitamin D and associated factors, among pregnant women in southeastern Nigeria.

In this prospective study on vitamin D and its associated factors conducted on 256 pregnant women from Anambra state of southeastern Nigeria, Vitamin D deficiency (VDD) occurred in 36 (14.1%). Vitamin D levels were significantly associated with parity, gestational age, social class, place of abode, skin colour, workplace location, and compliance to ANC drugs. Pregnant women with these features are considered to be at risk for vitamin D deficiency. The study however did not show any association between vitamin D and maternal age, social class of the pregnant women, and the season of the year. It is recommended that vitamin D supplementation be considered routinely for women with the risk factors - especially for the grandmultipara, women at term gestational age, women of dark complexion, those with indoor work location, and of urban habitat.Impact statementWhat is already known on this subject? Vitamin D is a fat-soluble vitamin primarily responsible for calcium and phosphorous homeostasis in the human body. it is derived in the human body both from endogenous sources through cutaneous synthesis following exposure to sunlight, and from endogenous conversion from pre-vitamin D to 25-hdroxycholecalciferol (25 (OH)D. Vitamin D is essential in pregnancy for maternal health, foetal skeletal growth and bone development. Vitamin D deficiency (VDD) in pregnancy occurs globally with a prevalence of 4.7% to as high as 80%.What do the results of this study add? This study shows that parity, gestational age, social class, place of domicile, skin colour, workplace location, and compliance to ANC drugs constitutes associated factors to vitamin D levels.What are the implications of these findings for clinical practice and/or further research? These findings imply that grandmultiparous pregnant women, women at term gestational age, of dark complexion, with indoor work location, and of urban habitat, by virtue of their relatively lower levels of vitamin D, should be considered for routine vitamin D supplementation.

Impact of thyroid function abnormalities on reproductive hormones during menstrual cycle in premenopausal HIV infected females at NAUTH, Nnewi, Nigeria.

BACKGROUND: This was a prospective study designed to evaluate the impact of thyroid function abnormalities on reproductive hormones during menstrual cycle in HIV infected females at Nnamdi Azikiwe University Teaching Hospital Nnewi, South-East Nigeria. METHODS: The study randomly recruited 35 Symptomatic HIV infected females and 35 Symptomatic HIV infected females on antiretroviral therapy (HAART) for not less than six weeks from an HIV clinic and 40 apparently heathy control females among the hospital staff of NAUTH Nnewi. They were all premenopausal females with regular menstrual cycle and aged between 15-45 years. Blood samples were collected at follicular and luteal phases of their menstrual cycle for assay of Thyroid indices (FT3, FT4 and TSH) and Reproductive indices (FSH, LH, Estrogen, Progesterone, Prolactin and Testosterone) using ELISA method. RESULTS: The result showed significantly higher FSH and LH but significantly lower progesterone (prog) and estrogen (E2) in the test females compared to control females at both phases of menstrual cycle (P<0.05). There was significantly lower FT3 but significantly higher TSH value in Symptomatic HIV females (P<0.05). FSH, LH and TSH values were significantly lowered while prog and FT3 were significantly higher in Symptomatic HIV on ART compared to Symptomatic HIV females (P<0.05). FT3, FT4, Prog and E2 were inversely correlated while FSH and LH were positively correlated with duration of HIV infection in HIV females (P<0.05 respectively). There was a direct correlation between CD4+ count and FT3 while inverse correlation was found between CD4+ count and TSH levels (P<0.05). DISCUSSION: The present study demonstrated hypothyroidism with a significant degree of primary hypogonadism in Symptomatic HIV infected females at both follicular and luteal phases of menstrual cycle which tends to normalize on treatments.

Lipid patterns, alcohol intake and BMI of adult Nigerians in a sub-urban slum in Enugu, Nigeria.

INTRODUCTION: Demonstration of cardiovascular disease (CVD) markers in healthy subjects with normal blood chemistry tests underscores the need to study social determinants of risk factors to aid primary prevention worldwide; particularly in slums which harbor nearly 80% of rural to urban migrants in the epidemiologically transiting Africa where CVDs were previously unknown. The objective of this study was to assess lipids in relationship to alcohol consumption and BMI in a Nigerian slum. METHODS: Cross sectional community based prevalent study involving 191 apparently healthy inhabitants aged 18-85 years recruited by convenient sampling. Heights, weights and BMIs were measured/ calculated, venous blood samples collected and lipid analysis done procedurally. Excel 13 and SPSS statistical soft ware were used for analysis and chart representation. RESULTS: THEIR MEAN PARAMETERS WERE: Age (43.87±1.62 years), triglycerides (TG; 1.20±0.08 mmol/L), total Cholesterol (TC; 4.54±1.70 mmol/L), low density lipoprotein cholesterol (LDLC; 3.69±1.69 mmol/L), high density lipoprotein cholesterol (HDLC; 0.61±0.24 mmol/L), RPI (7.12±5.24), body mass index (BMI; 25.08±5.18 Kg/M2). TG and HDLC values were lowest in obese non alcohol drinkers while all other lipid parameters increased with BMI in both drinkers and non drinkers. Low HDLC prevalence was lowest in obese alcohol drinkers and highest (100%) in their non drinking counterparts. Having favourable HDLC was highest in daily alcohol consumers. No weekly drinker (0%) had favourable HDLC. CONCLUSION: Ignorance, poor nutritional and health education may be major factors in the strategic challenge posed by the emergence of non communicable diseases in Africans.
