Maternal and cord blood collected from 33 Nigerian mother-child pairs were tested for measles-sepcific IgG. All 33 had protective measles antibodies at the time of delivery with a positive correlation of r = 0.87. Determination of the rate of waning of these antibodies revealed that 58 per cent of these children had lost the protective maternal antibody by the age of 4 months and only 3 per cent of the children had enough antibody to protect them between the ages of 6-9 months. Fifty-five colostrum samples from the same mothers and 347 breastmilk samples collected at various periods of breastfeeding also showed that anti-measles IgA had dropped below the protective cut-off within the first 2 weeks of birth. It is evident that the Nigerian child is born with solid anti-measles antibody but the rate of waning has left a large number unprotected before the first dose of the vaccine. There is an urgent need to review the measles vaccination programme in Nigeria to protect these susceptible infants.

Air-drying characteristics of fresh and osmotically pretreated (40°B, 50°B and 60°B sucrose solutions for 9 h) four pepper cultivars namely, Rodo (Capsicum annuum), Shombo (Capsicum frutescens), Bawa (Capsicum frutenscens) and Tatashe (Capsicum annuum), and CIE L*a*b* parameters of air-dried (50, 60, 70 and 80°C) peppers were investigated. Moisture diffusivity and activation energy (E a ) were calculated from Fick's law and analogous Arrhenius equation, respectively. Colour difference, chroma and hue angle of fresh-and osmo-oven dried peppers were evaluated. Drying rates occurred predominantly in the falling rate. Moisture diffusivity varied from 8.071×10 −10 -1.048×10 −8 , 7.710×10 −11 -1.018×10 −9 , 9.807×10 −9 -1.746×10 -8 and 8.748×10 −10 -1.464×10 −9 m 2 /s for Bawa, Rodo, Shombo, and Tatashe, respectively. E a for moisture diffusion during drying of peppers varied from 53.86 to 84.86 kJ/mol and was affected by cultivars and osmotic pretreatment concentration. Osmotic pretreatment and drying temperature had significant effect (p<0.05) on a*, b*, chroma and hue angle values of dried peppers.

ObjectivesLiterature has assessed skilled birth attendants (SBAs) utilisation, but little is known about what contributes to the changes in SBA use. Multivariate decomposition analysis was thus applied in this study to examine; levels, trends, inequalities and drivers of changes in SBA utilisation.Design and settingA cross-sectional analysis of five-waves of NDHS-data (1990, 2003, 2008, 2013, and 2018), collected through similar multistage sampling across the 36 states and the federal-capital-territory of Nigeria.ParticipantsWomen of reproductive age (15–49 years), and with at least one birth in the last 5 years preceding each of the surveys.Main outcome measureSBA use is the response variable while explanatory variables were classified into; Demographics, Health, Economic and Corporal factors.MethodsChi-square test for trends of proportions across the ordered survey years assessed trends in SBA use. MDA that quantifies and partition predictors effect into endowment and coefficient components evaluated contributors to changes in SBA use. Statistical analysis was carried out at a 95% confidence interval in Stata 16.ResultsSBA use increased with significant (p<0.05) linear trends by 12% between 2003 and 2018. The decomposition analysis showed that differences in characteristics (endowment) accounted for 11.5% of the changes while the remaining 88.5% were due to differences in effects (coefficient). SBA utilisation rises by 61% when respondents decided on her health compared to when such decisions were made by the spouse. Utilisation of SBA, however, fell by 88% among women who reside in the states with high rural populations percentage.ConclusionsSBA use remained low in Nigeria, and slowly increase at the rate of <1% yearly. Women health decision-making power contributed most to positive changes. Residing in states with high rural populations has a negative impact on SBA use. Maternal health programmes that strengthen women’s health autonomy and capacity building in rural communities should be encouraged.

Background Completing maternity continuum of care from pregnancy to postpartum is a core strategy to reduce the burden of maternal and neonatal mortality dominant in sub-Saharan Africa, particularly Nigeria. Thus, we evaluated the level of completion, dropout and predictors of women uptake of optimal antenatal care (ANC) in pregnancy, continuation to use of skilled birth attendants (SBA) at childbirth and postnatal care (PNC) utilization at postpartum in Nigeria. Methods A cross-sectional analysis of nationally representative 21,447 pregnancies that resulted to births within five years preceding the 2018 Nigerian Demographic Health Survey. Maternity continuum of care model pathway based on WHO recommendation was the outcome measure while explanatory variables were classified as; socio-demographic, maternal and birth characteristics, pregnancy care quality, economic and autonomous factors. Descriptive statistics describes the factors, backward stepwise regression initially assessed association (p < 0.10), multivariable binary logistic regression and complementary-log–log model quantifies association at a 95% confidence interval (α = 0.05). Results Coverage decrease from 75.1% (turn-up at ANC) to 56.7% (optimal ANC) and to 37.4% (optimal ANC and SBA) while only 6.5% completed the essential continuum of care. Dropout in the model pathway however increase from 17.5% at ANC to 20.2% at SBA and 30.9% at PNC. Continuation and completion of maternity care are positively drive by women; with at least primary education (AOR = 1.27, 95%CI = 1.01–1.62), average wealth index (AOR = 1.83, 95%CI = 1.48 –2.25), southern geopolitical zone (AOR = 1.61, 95%CI = 1.29–2.01), making health decision alone (AOR = 1.39, 95%CI = 1.16–1.66), having nurse as ANC provider (AOR = 3.53, 95%CI = 2.01–6.17) and taking at least two dose of tetanus toxoid vaccine (AOR = 1.25, 95%CI = 1.06–1.62) while women in rural residence (AOR = 0.78, 95%CI = 0.68–0.90) and initiation of ANC as late as third trimester (AOR = 0.44, 95%CI = 0.34–0.58) negatively influenced continuation and completion. Conclusions 6.5% coverage in maternity continuum of care completion is very low and far below the WHO recommended level in Nigeria. Women dropout more at postnatal care than at skilled delivery and antenatal. Education, wealth, women health decision power and tetanus toxoid vaccination drives continuation and completion of maternity care. Strategies optimizing these factors in maternity packages will be supreme to strengthen maternal, newborn and child health.

Infiltration of water into the soil is an important physical process affecting the fate of water under field conditions, especially the amount of subsurface recharge and surface runoff and hence the hazard of soil erosion. The study was conducted to evaluate the infiltration models of soils developed on coastal plain sands and to select a suitable models as a basis to improve the management of the soil. A total of 16 infiltration runs were made with the double ring infiltrometer. For the purpose of getting best fitting model, the results obtained from various infiltration models were compared with observed field data. The parameters considered for best fitting of model were correlation coefficient and coefficient of variability (CV). Model-predicted cumulative infiltration consistently deviated from field-measured data, that is, the models under-predicted cumulative infiltration by several orders of magnitude for Kostiakov, Green Ampt and Philip model but the model over predicted cumulative infiltration for Horton model. The results of the soil samples analysed revealed that the mean values of 707.50, 208.13 and 84.38 gkg-1 for sand, silt and clay with the textural class of sandy loam. The bulk density, particle density and total porosity had mean values of 1.84 gcm-3, 2.44 gcm-3 and 22.56%. However, there was a fairly good agreement between mean-measured cumulative infiltration (7.30 cm/hr, CV = 32.19%); Philips (1.93 cm/hr, CV = 42.49%); Kostiakov (0.13 cm/hr, CV = 30.77%); Horton (64.49 cm/hr, CV = 22.39%) and Green Ampt model (42.04 cm/hr, CV = 0.57%) respectively. The data however showed that the correlation coefficient for Kostiakov (1.00) was best fitting in predicting the field measured data and this was closely followed by Green Ampt (0.88); while Philip’s model and Horton model showed a negative correlation (r = -0.88 and r = -0.82) with the field measured data. Conservation measures involving mulching, cover cropping and afforestation are recommended to improve the soil structure and infiltration capacity.

Background Despite uptake of antenatal care (ANC), 70% of global burden of maternal and child mortality is prevalent in sub-Saharan Africa, particularly Nigeria, due to persistent home delivery. Thus, this study investigated the disparity and barriers to health facility delivery and the predictors of home delivery following optimal and suboptimal uptake of ANC in Nigeria. Methodology A secondary analysis of 34882 data from 3 waves of cross-sectional surveys (2008–2018 NDHS). Home delivery is the outcome while explanatory variables were classified as socio-demographics, obstetrics, and autonomous factors. Descriptive statistics (bar chart) reported frequencies and percentages of categorical data, median (interquartile range) summarized the non-normal count data. Bivariate chi-square test assessed relationship at 10% cutoff point (p < 0.10) and median test examined differences in medians of the non-normal data in two groups. Multivariable logistic regression (Coeff plot) evaluated the likelihood and significance of the predictors at p < 0.05. Results 46.2% of women had home delivery after ANC. Only 5.8% of women with suboptimal ANC compared to the 48.0% with optimal ANC had facility delivery and the disparity was significant (p < 0.001). Older maternal age, SBA use, joint health decision making and ANC in a health facility are associated with facility delivery. About 75% of health facility barriers are due to high cost, long distance, poor service, and misconceptions. Women with any form of obstacle utilizing health facility are less likely to receive ANC in a health facility. Problem getting permission to seek for medical help (aOR = 1.84, 95%CI = 1.20–2.59) and religion (aOR = 1.43, 95%CI = 1.05–1.93) positively influence home delivery after suboptimal ANC while undesired pregnancy (aOR = 1.27, 95%CI = 1.01–1.60) positively influence home delivery after optimal ANC. Delayed initiation of ANC (aOR = 1.19, 95%CI = 1.02–1.39) is associated with home delivery after any ANC. Conclusions About half of women had home delivery after ANC. Hence disparity exist between suboptimal and optimal ANC attendees in institutional delivery. Religion, unwanted pregnancy, and women autonomy problem raise the likelihood of home delivery. Four-fifth of health facility barriers can be eradicated by optimizing maternity package with health education and improved quality service that expand focus ANC to capture women with limited access to health facility.
