Trends and socioeconomic inequality of the burden of congenital abnormalities of the kidney and urinary tract among children and adolescents.

BACKGROUND: Although congenital abnormalities of the kidney and urinary tract (CAKUT) is the leading cause of childhood onset chronic kidney disease (CKD) and kidney failure, comprehensive information on the disease burden among children and adolescents globally is lacking. We aim to report the trends and socioeconomic inequality of CAKUT burden for people aged 0-24 years from 1990 to 2019·. METHODS: We reported the prevalence, mortality and disability-adjusted life-years (DALYs) for CAKUT based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, quantified the association of disease burden and socio-demographic index (SDI), calculated the slope index of inequality (SII) the relative index of inequality (RII) and concentration index. RESULTS: In 2019, the global prevalence, mortality, and DALYs of CAKUT among individuals aged 0-24 years were 167.11 (95%Confident Interval 166.97, 167.25), 0.30 (0.29, 0.30), and 32.22 (32.16, 32.29) per 100 000 population. The greatest prevalence, mortality and DALYs were recorded in the 0-4 year age group. The greatest mortality and DALYs were recorded in low SDI countries and territories. During 1990 to 2019, the prevalence, mortality and DALYs decreased globally, while in low and low-middle countries and territories the reduction was much less slower. India, Nigeria and Pakistan had the highest DALYs. Saudi Arabia and China exhibited a markedly decrease of CAKUT burden. Globally for every 0.1 increase in SDI, there was a 20.53% reduction in mortality, a 16.31% decrease in DALYs, but a 0.38% rise in prevalence. CONCLUSIONS: Inequality for disease burden of varying SDI was increasing globally. Thus, specific preventive and health service measures are needed to reduce the global burden from CAKUT.

Incidence, predictors and immediate neonatal outcomes of birth asphyxia in Nigeria.

OBJECTIVE: To determine the incidence and sociodemographic and clinical risk factors associated with birth asphyxia and the immediate neonatal outcomes of birth asphyxia in Nigeria. DESIGN: Secondary analysis of data from the Maternal and Perinatal Database for Quality, Equity and Dignity Programme. SETTING: Fifty-four consenting referral-level hospitals (48 public and six private) across the six geopolitical zones of Nigeria. POPULATION: Women (and their babies) who were admitted for delivery in the facilities between 1 September 2019 and 31 August 2020. METHODS: Data were extracted and analysed on prevalence and sociodemographic and clinical factors associated with birth asphyxia and the immediate perinatal outcomes. Multilevel logistic regression modelling was used to ascertain the factors associated with birth asphyxia. MAIN OUTCOME MEASURES: Incidence, case fatality rate and factors associated with birth asphyxia. RESULTS: Of the available data, 65 383 (91.1%) women and 67 602 (90.9%) babies had complete data and were included in the analysis. The incidence of birth asphyxia was 3.0% (2027/67 602) and the case fatality rate was 16.8% (339/2022). The risk factors for birth asphyxia were uterine rupture, pre-eclampsia/eclampsia, abruptio placentae/placenta praevia, birth trauma, fetal distress and congenital anomaly. The following factors were independently associated with a risk of birth asphyxia: maternal age, woman's education level, husband's occupation, parity, antenatal care, referral status, cadre of health professional present at the birth, sex of the newborn, birthweight and mode of birth. Common adverse neonatal outcomes included: admission to a special care baby unit (SCBU), 88.4%; early neonatal death, 14.2%; neonatal sepsis, 4.5%; and respiratory distress, 4.4%. CONCLUSIONS: The incidence of reported birth asphyxia in the participating facilities was low, with around one in six or seven babies with birth asphyxia dying. Factors associated with birth asphyxia included sociodemographic and clinical considerations, underscoring a need for a comprehensive approach focused on the empowerment of women and ensuring access to quality antenatal, intrapartum and postnatal care.

Prevalence, perinatal outcomes and factors associated with neonatal sepsis in Nigeria.

OBJECTIVE: To examine the prevalence, perinatal outcomes and factors associated with neonatal sepsis in referral-level facilities across Nigeria. DESIGN: Secondary analysis of data from the Maternal and Perinatal Database for Quality, Equity and Dignity Programme in 54 referral-level hospitals across Nigeria. SETTING: Records covering the period from 1 September 2019 to 31 August 2020. POPULATION: Mothers admitted for birth during the study period, and their live newborns. METHODS: Analysis of prevalence and sociodemographic and clinical factors associated with neonatal sepsis and perinatal outcomes. Multilevel logistic regression modelling identified factors associated with neonatal sepsis. MAIN OUTCOME MEASURES: Neonatal sepsis and perinatal outcomes. RESULTS: The prevalence of neonatal sepsis was 16.3 (95% CI 15.3-17.2) per 1000 live births (1113/68 459) with a 10.3% (115/1113) case fatality rate. Limited education, unemployment or employment in sales/trading/manual jobs, nulliparity/grand multiparity, chronic medical disorder, lack of antenatal care (ANC) or ANC outside the birthing hospital and referral for birth increased the odds of neonatal sepsis. Birthweight of <2500 g, non-spontaneous vaginal birth, preterm birth, prolonged rupture of membranes, APGAR score of <7 at 5 min, birth asphyxia, birth trauma or jaundice were associated with neonatal sepsis. Neonates with sepsis were more frequently admitted to a neonatal intensive care unit (1037/1110, 93.4% vs 8237/67 346, 12.2%) and experienced a higher rate of death (115/1113, 10.3% vs 933/67 343, 1.4%). CONCLUSIONS: Neonatal sepsis remains a critical challenge in neonatal care, underscored by its high prevalence and mortality rate. The identification of maternal and neonatal risk factors underscores the importance of improved access to education and employment for women and targeted interventions in antenatal and intrapartum care.

Improving struggling medical and nursing students' subjective vitality, school engagement and academic performance through a peer mentorship intervention programme: an intervention protocol.

BACKGROUND: The undergraduate medical training programme is demanding and rigorous. This underlines the importance of a peer mentorship strategy to improve the well-being, self-determination, school connectedness, and performance of struggling medical and nursing students. This study is aimed at identifying struggling medical and nursing students using two cumulative continuous assessment test (CAT) scores, assess their subjective vitality and school engagement and evaluate the impact of the peer mentorship intervention on them. METHODS: The study will adopt a mixed-methods approach and will be conducted in the medical colleges of Nnamdi Azikiwe University, Awka, Nigeria, and the University of Rwanda. Three instruments will be used: The subjective Vitality Scale (SVS), the University Student Engagement Inventory (USEI), and the academic records of the students before and after the commencement of the intervention programme. The consenting least-performing medical and nursing students identified by their low CAT scores (below 45%) in basic medical sciences will be selected for study in each institution. The outcome measures will include students' CAT scores, subjective vitality, and school engagement scores. The data will be analysed both quantitatively and qualitatively. Thematic content analysis will be adopted in the analysis of the responses generated from the focus group discussion. The mean ± standard deviation or median and interquartile range statistic will be adopted for the quantitative data. DISCUSSION: Given the paucity of data on struggling medical and nursing students in Nigeria and Rwanda, this research was designed to help in exploring evidence-based interventions to improve and prevent poor subjective well-being of struggling students. The study is expected to fill these knowledge gaps. TRIAL REGISTRATION: Pan African Clinical Trial registry, PACTR202405546896613, registration date: 27th May, 2024.

A 17 year experience of attrition from care among HIV infected children in Nnewi South-East Nigeria.

BACKGROUND: A large number of HIV-infected children continue to die despite reported scale-up of paediatric HIV services. AIM: The trend in attrition among children enrolled in an anti-retroviral therapy (ART) programme was evaluated. METHODS: This was a retrospective review of children enrolled into NAUTH ART programme between 2003 and 2019. RESULTS: 1114 children < 15 years at enrolment were studied. The male: female ratio was 1:1 while median age at enrolment was 4.3 years. About two-thirds had WHO stage 3 or 4 disease at enrolment. The rate of loss to follow-up (LTFU) and death were 41.0 and 8.4%, respectively, with overall attrition incidence of 108/1000PY. Despite the downward trend, spikes occurred among those enrolled in 2008 to 2011 and in 2017. The trend in 6-, 12-, 24- and 36-months attrition varied similarly with overall rates being 20.4, 27.7, 34.3 and 37.3%, respectively. Among those on ART, > 50% of attrition was recorded within 6 months of care. Advanced WHO stage, young age, non-initiation on ART or period of enrolment (P <  0.001), and caregiver (p = 0.026) were associated with attrition in bivariate analysis. Apart from caregiver category, these factors remained significant in multivariate analysis. Most LTFU could not be reached on phone. Among those contacted, common reasons for being lost to follow-up were financial constraints, caregiver loss, claim to divine healing, family disharmony/child custody issues and relocation of family/child. CONCLUSION/RECOMMENDATION: Attrition rate was high and was mostly due to LTFU. Predictors of attrition were late presentation, young age, delay in ART initiation and financial constraints. Efforts should be intensified at early diagnosis, linkage to care and implementation of "test and treat" strategy. Innovative child centered approaches should be adopted to enable the HIV-infected children remain in care despite challenges which can truncate treatment.

Prevalence, seroconversion and mother-to-child transmission of dual and triplex infections of HIV, hepatitis B and C viruses among pregnant women in Nigeria: study protocol.

BACKGROUND: Nigeria contributes significantly to the global burden of HIV, Hepatitis B and C infections, either singly or in combinations, despite progress in HIV care regionally and globally. Although some limited data on mono infection of HIV, Hepatitis B and C virus infections do exists, that of dual and triplex infections, including seroconversion and mother-to-child transmission (MTCT) rates necessary for planning to address the scourge of infections in pregnancy are not available. OBJECTIVES: To determine the seroprevalence, rate of new infections, MTCT of dual and triple infections of HIV, Hepatitis B and C viruses and associated factors, among pregnant women in Nigeria. METHOD: A multicenter prospective cohort study will be conducted in six tertiary health facilities randomly selected from the six geopolitical zones of Nigeria. All eligible pregnant women are to be tested at enrollment after informed consent for HIV, Hepatitis B and C virus infections. While those positive for at least two of the infections in any combination will be enrolled into the study and followed up to 6 weeks post-delivery, those negative for the three infections or positive for only one of the infections at enrolment will be retested at delivery using a rapid diagnostic test. On enrolment into the study relevant information, will be obtained, and laboratory test of CD4 count, liver function test and full blood counts, and prenatal ultrasonography will also be obtained/performed. Management of mother-newborns pairs will be according to appropriate national guidelines. All exposed newborns will be tested for HIV, HBV or HCV infection at birth and 6 weeks using PCR technique. The study data will be documented on the study case record forms. Data will be managed with SPSS for windows version 23. Ethical approval was obtained from National Health Research Ethics Committee (NHREC) (NHREC/01/01/2007-23/01/2020). CONCLUSION: Pregnant women with multiple of HIV, HBV and HCV infections are at increased risk of hepatotoxicity, maternal and perinatal morbidity and mortality. Additionally, infected pregnant women transmit the virus to their unborn baby even when asymptomatic. Children born with any of the infection have significantly poorer quality of life and lower five-year survival rate. Unfortunately, the seroconversion and MTCT rates of dual or triplex infections among pregnant women in Nigeria have not been studied making planning for prevention and subsequent elimination of the viruses difficult. The study is expected to fill this knowledge gaps. Nigeria joining the rest of the world to eliminate the triple infection among children rest on the availability of adequate and reliable data generated from appropriately designed, and powered study using representative population sample. The establishment of the three-in-one study of prevalence, rate of new infection, rate and risk factor for MTCT of dual and triple infection of HIV, Hepatitis B and C viruses among pregnant women in Nigeria is urgently needed for policy development and planning for the improvement of the quality of life of mothers and the elimination of childhood triplex infection.

Caregiver satisfaction with paediatric HIV treatment and care in Nigeria and equity implications for children living with HIV.

Caregiver satisfaction has the potential to promote equity for children living with HIV, by influencing health-seeking behaviour. We measured dimensions of caregiver satisfaction with paediatric HIV treatment in Nigeria, and discuss its implications for equity by conducting facility-based exit interviews for caregivers of children receiving antiretroviral therapy in 20 purposively selected facilities within 5 geopolitical zones. Descriptive analysis and factor analysis were performed. Due to the hierarchical nature of the data, multilevel regression modelling was performed to investigate relationships between satisfaction factors and socio-demographic variables. Of 1550 caregivers interviewed, 63% (95% CI: 60.6-65.4) reported being very satisfied overall; however, satisfaction varied in some dimensions: only 55.6% (53.1-58.1) of caregivers could talk privately with health workers, 56.9% (54.4-59.3) reported that queues to see health workers were too long, and 89.9% (88.4-91.4) said that some health workers did not treat patients living with HIV with sufficient respect. Based on factor analysis, two underlying factors, labelled Availability and Attitude, were identified. In multilevel regression, the satisfaction with availability of services correlated with formal employment status (p < .01), whereas caregivers receiving care in private facilities were less likely satisfied with both availability (p < .01) and attitude of health workers (p < .05). State and facility levels influenced attitudes of the health workers (p < .01), but not availability of services. We conclude that high levels of overall satisfaction among caregivers masked dissatisfaction with some aspects of services. The two underlying satisfaction factors are part of access typology critical for closing equity gaps in access to HIV treatment between adults and children, and across socio-economic groups.

Menstrual hygiene practices of adolescent secondary school girls in rural Anambra communities.

BACKGROUND: Adolescent girls face numerous challenges which hinder their ability to manage menstruation in a healthy and dignified manner. OBJECTIVES: To examine the menstrual hygiene practices of adolescent girls schooling in rural Anambra communities. STUDY DESIGN: Cross-sectional descriptive study. METHOD: Participants were selected using multistage stratified random sampling technique and interviewed using self-administered semi-structured questionnaire. Data were analysed using Statistical Package for Social Sciences version 22.0. RESULTS: Mean age of all, pre-menarche and post-menarche girls were 14.7 ± 1.84, 12.8 ± 1.09 and 15.1 ± 1.73 years, respectively. About 46% of the pre-menarche girls had not received any information on menstruation. Common sources of initial menstruation information were mother (87.3%), school (52.2%) and peers (20.0%). Among the 1091 (85.0% (1091/1283)) post-menarche girls, last menstrual period, last menstrual period duration and cycle length could not be recalled by 53.9%, 34.4% and 39.3%, respectively. Majority (98.3%) who could recall last menstrual period had a cycle length of ⩽30 days and the mean duration of menses was 4.4 ± 0.84 days. Disposable sanitary pad was mostly (60%) cited as recommended product, but cloth/rags (40.6%) or tissue paper (32. 3%) were predominantly used. Majority (88.6%) took their bath ⩾twice/day, 50.9% changed sanitary product ⩽twice/day while 72.5% exhibited poor hand washing. Sanitary products were mostly discarded by burning (45.4%). Fifty-one percent could not change in school predominantly due to lack of functional toilets/changing rooms (84.2%) while 72.5% of those who changed did so in bushes or unused spaces. Challenges faced during menstruation include restriction from holy places (38.9%), waist pain (74.9%), blood stains (36.1%) and lack of money to buy pad (27.0%). Factors significantly associated with using commercial pads were age (p = 0.047), class (p = 0.006), mother's educational status (p < 0.001), social class (p < 0.001), ability to recall last menstrual period date (p = 0.029) or duration (p = 0.001). CONCLUSION: Menstrual hygiene management was unsatisfactory among studied adolescents. Continuous education of adolescent girls on menstrual hygiene management and advocacy for adequate menstrual hygiene management support are imperative.

A Systematic Review and Meta-Analysis of the Prevalence of Triplex Infections (Combined Human Immunodeficiency Virus, Hepatitis B Virus, and Hepatitis C Virus) among Pregnant Women in Nigeria.

Objective: We systematically identified the prevalence of triplex infections (combined human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV)) in pregnancy. Methods: To gather information on the frequency of triplex infections, we searched the databases of PubMed, CINAHL, and Google Scholar. Without regard to language, we utilized search terms that covered HIV, HBV, HCV, and pregnancy. Pregnant women with triplex infections of HIV, HBV, and HCV were included in studies that also examined the prevalence of triplex infections. Review Manager 5.4.1 was employed to conduct the meta-analysis. Critical appraisal and bias tool risk data were provided as percentages with 95% confidence intervals (95% CIs), and I2 was used as the statistical measure of heterogeneity. The checklist was created by Hoy and colleagues. The study protocol was registered on PROSPERO, under the registration number CRD42020202583. Results: Eight studies involving 5314 women were included. We identified one ongoing study. Pooled prevalence of triplex infections was 0.03% (95% CI: 0.02-0.04%) according to meta-analysis. Subgroup analysis demonstrated a significantly high prevalence of 0.08% (95% CI: 0.06-0.10%; 3863 women) in HIV-positive population than 0.00% (95% CI:-0.00-0.00; 1451 women; P < 0.001) in general obstetric population. Moreover, there was a significant difference in the pooled prevalence between studies published between 2001 and 2010 and between 2011 and 2021 (0.14% (95% CI: 0.12 to 0.16 versus 0.03% (95% CI: 0.02 to 0.04%; P < 0.001))) and participants recruited in the period between 2001 and 2011 and between 2012 and 2021 (0.13% (95% CI: 0.05 to 0.21; p=0.002 versus 0.00% (95% CI: -0.00 to 0.00%; p=1.00))), respectively. Conclusion: The combined prevalence of prenatal triplex infections was 0.03%, with rates notably higher among the group of pregnant women who were HIV-positive and during the recruitment period that took place before 2012. This prevalence still necessitates screening for these infections as necessary.

Bacterial isolates, antibiogram and outcomes of blood culture proven sepsis in neonates at a tertiary institution in South East Nigeria: a cross-sectional study.

Background: Neonatal sepsis (NNS) in developing countries continues to be a diagnostic and management challenge due to the delays in identifying the aetiologic pathogens and antibiograms. Aim: To determine the predominant bacterial isolates, antibiotic susceptibility pattern and outcomes of blood culture proven sepsis in neonates. Methodology: A hospital-based cross-sectional study of 120 neonates admitted into the Special Care Baby Unit (SCBU) of Nnamdi Azikiwe University Teaching Hospital Nnewi with clinical features suggestive of sepsis. A semi-structured questionnaire and proforma were used to record neonatal, maternal and laboratory information. Blood specimens were collected for aerobic culture using Bactenecin (BACTEC)-Ped plus culture system. Antibiotic susceptibility testing was performed using the Kirby Bauer disc diffusion method. Data obtained were analysed using SPSS version 23.0. p value < 0.05 was considered as significant. Results: There were 68 males and 52 females giving a male-to-female ratio of 1.3:1. The median age at admission was 48 h. Staphylococcus aureus 13 (43.3%) was the most common bacteria isolated. The prevalence of blood culture proven sepsis were 25% and 6.7% of the subjects with positive blood culture died. Gram-positive bacteria isolated were sensitive to gentamicin, vancomycin (VA), linezolid and resistant to penicillin. Gram-negative bacteria isolated were sensitive to meropenem (MEM), imipenem (IPM), ciprofloxacin (CIP) and resistant to ceftazidime, ceftriaxone, ampicillin and amoxicillin-clavulanic acid. Conclusion: The most common bacteria isolated causing NNS using BACTEC automated blood culture system was Staphylococcus aureus. The empirical antibiotics considered for use at the study site are gentamycin, VA for Gram-positive organisms and CIP, IPM and MEM for Gram-negative organisms. Some of the participants with positive blood culture died. Therefore, there is a need for regular antibiogram profiles in all hospitals offering neonatal care.

Mother-to-child transmission of human immunodeficiency virus, hepatitis B virus and hepatitis C virus among pregnant women with single, dual or triplex infections of human immunodeficiency virus, hepatitis B virus and hepatitis C virus in Nigeria: A systematic review and meta-analysis.

Objectives: To systematically review literature and identify mother-to-child transmission rates of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus among pregnant women with single, dual, or triplex infections of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in Nigeria. PRISMA guidelines were employed. Searches were on 19 February 2021 in PubMed, Google Scholar and CINAHL on studies published from 1 February 2001 to 31 January 2021 using keywords: "MTCT," "dual infection," "triplex infection," "HIV," "HBV," and "HCV." Studies that reported mother-to-child transmission rate of at least any of human immunodeficiency virus, hepatitis B virus and hepatitis C virus among pregnant women and their infant pairs with single, dual, or triplex infections of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus in Nigeria irrespective of publication status or language were eligible. Data were extracted independently by two authors with disagreements resolved by a third author. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary mother-to-child transmission rates in terms of percentage with 95% confidence interval. Protocol was prospectively registered in PROSPERO: CRD42020202070. The search identified 849 reports. After screening titles and abstracts, 25 full-text articles were assessed for eligibility and 18 were included for meta-analysis. We identified one ongoing study. Pooled mother-to-child transmission rates were 2.74% (95% confidence interval: 2.48%-2.99%; 5863 participants; 15 studies) and 55.49% (95% confidence interval: 35.93%-75.04%; 433 participants; three studies), among mother-infant pairs with mono-infection of human immunodeficiency virus and hepatitis B virus, respectively, according to meta-analysis. Overall, the studies showed a moderate risk of bias. The pooled rate of mother-to-child transmission of human immunodeficiency virus was 2.74% and hepatitis B virus was 55.49% among mother-infant pairs with mono-infection of HIV and hepatitis B virus, respectively. No data exists on rates of mother-to-child transmission of hepatitis C virus on mono-infection or mother-to-child transmission of human immunodeficiency virus, hepatitis B virus, and hepatitis C virus among mother-infant pairs with dual or triplex infection of HIV, hepatitis B virus and HCV in Nigeria.

A Review and Analysis of Outcomes from Prevention of Mother-to-Child Transmission of HIV Infant Follow-up Services at a Pediatric Infectious Diseases Unit of a Major Tertiary Hospital in Nigeria: 2007-2020.

BACKGROUND AND OBJECTIVE: Above 90% of childhood HIV infections result from mother-to-child transmission (MTCT). This study examined the MTCT rates of HIV-exposed infants enrolled in the infant follow-up arm of the prevention of mother-to-child transmission (PMTCT) program in a teaching hospital in Southeast Nigeria. METHODS: This was a 14-year review of outcomes of infants enrolled in the infant follow-up arm of the PMTCT program of Nnamdi Azikiwe University Teaching Hospital Nnewi, Nigeria. The majority of subjects were enrolled within 72 hours of birth and were followed up until 18 months of age according to the National Guidelines on HIV prevention and treatment. At enrollment, relevant data were collected prospectively, and each scheduled follow-up visit was recorded both electronically and in physical copy in the client's folders. Data were analyzed using SPSS version 20. The major outcome variable was final MTCT status. RESULTS: Out of 3,784 mother-infant dyads studied 3,049 (80.6%) received both maternal and infant Antiretroviral (ARV) prophylaxis while 447 (11.8%) received none. The MTCT rates were 1.4%, 9.3%, 24.1%, and 52.1% for both mother and infant, mother only, infant only, and none received ARV prophylaxis respectively. There was no gender-based difference in outcomes. The MTCT rate was significantly higher among mixed-fed infants (p<0.001) and among those who did not receive any form of ARVs (p<0.001). Among dyads who received no ARVs, breastfed infants significantly had a higher MTCT rate compared to never-breastfed infants (57.9% vs. 34.8%; p<0.001). The MTCT rate was comparable among breastfed (2.5%) and never-breastfed (2.1%) dyads who had received ARVs. After logistic regression, maternal (p<0.001, OR: 7.00) and infant (p<0.001, OR: 4.00) ARV prophylaxis for PMTCT remained significantly associated with being HIV-negative. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: Appropriate use of ARVs and avoidance of mixed feeding in the first six months of life are vital to the success of PMTCT programs in developing countries. PMTCT promotes exclusive breastfeeding and reduces the burden of pediatric HIV infection, thereby enhancing child survival.

Public Knowledge and Opinion on Childhood Routine Immunizations in Two Major Cities of Anambra State, Nigeria.

BACKGROUND: Immunization programs suffer recurrent setbacks in developing countries. PURPOSE: We evaluated the knowledge and opinion of parents towards childhood immunization. MATERIALS AND METHODS: A cross-sectional study was conducted among 2400 parents/guardians in two major Anambra cities. RESULTS: The male:female ratio was 1:1 and about two-third (64.3%) of respondents were aged 21-40 years. The majority were married (85.0%), Christians (88.3%), and had heard about childhood immunization (92.3%) mainly from formal settings (56.5%). A little above half (56.2%) of them correctly cited "disease prevention" as reason for childhood immunization. A larger proportion of those that gave this correct response worked in tertiary institutions and had post-secondary school education (p<0.001). The majority of the respondents appropriately agreed or disagreed with opinions that can influence immunization uptake. However, some of them did not agree that immunization was important during the first year of life (16.7%) or afterwards (23.1%); to ensure full immunization (22.8%) or maintain proper immunization records (25.6%) of their children; and to actively support childhood immunization (33.9%). Likewise, some respondents would withhold immunization for perceived fear of adverse reactions (30.7%) or if naturally acquired infection was perceived to confer better protection (28.2%). Respondents who worked in tertiary institutions, and had higher education or family income were more likely to agree or disagree appropriately to opinions. Males had comparable opinions with females although females seemed to do better in opinions that reflect actual vaccination practice. CONCLUSION: Awareness of the term "immunization" was high although knowledge of its indication did not measure up with this awareness, especially among the less educated. Most parents, especially those who worked in tertiary institutions,r had higher income, or education, were favorably disposed towards opinions that could positively influence immunization uptake. Efforts should be intensified at improving awareness on the indication, benefits and safety of immunization, and improving public opinions in order to optimize childhood immunization.

Awareness and prevalence of hepatitis C virus infection among pregnant women in Nigeria: A national pilot cross-sectional study.

BACKGROUND: There are no national data on hepatitis C virus awareness and burden among pregnant women to justify its routine screening. OBJECTIVES: To investigate awareness, seroprevalence and risk factors for hepatitis C virus infection among pregnant women in Nigeria. METHODS: A total of 159 pregnant women from antenatal clinics across six geopolitical zones in Nigeria consented to anti-hepatitis C virus testing which was confirmed using polymerase chain reaction technique. Confirmed hepatitis C virus positive women were further tested for hepatitis B and HIV. Participants were evaluated for risk factors for hepatitis C virus. Odds ratios, adjusted odds ratios, and their 95% confidence intervals (CIs) were determined, and p-values of <0.05 were considered significant. RESULTS: Of 159 participants, 77 (48.4%; 95% confidence interval = 38.2%-60.5%) were aware of hepatitis C virus infection and awareness of hepatitis C virus was associated with young age (odds ratio = 2.21; 95% confidence interval = 1.16-4.21), high educational level (odds ratio = 3.29; 95% confidence interval = 1.63-6.64), and participants' occupation (odds ratio = 0.51; 95% confidence interval = 0.26-0.99). In multivariable logistic regression, adjusted for confounders, the association between awareness of hepatitis C virus and participants' young age (adjusted odds ratio = 1.60; 95% confidence interval = 1.09-2.35; p = 0.018) and high educational level (adjusted odds ratio = 1.48; 95% confidence interval = 1.17-1.86; p = 0.001) remained significant. Hepatitis C virus seroprevalence was found to be 1.3% (95% confidence interval = 0.2%-4.5%). All (100.0%, 95% confidence interval = 12.1%-100.0%) the hepatitis C virus-positive participants and 99 (63.1%, 95% confidence interval = 51.3%-76.8%) hepatitis C virus-negative participants had identifiable hepatitis C virus risk factors. Dual seropositivity of anti-hepatitis C virus/anti-HIV and anti-hepatitis C virus/hepatitis B surface antigen each accounted for 0.6%. The most identified risk factors were multiple sexual partners (15.7%), shared needles (13.8%), and blood transfusion (11.3%). There was no significant association between the risk factors and hepatitis C virus positive status. CONCLUSION: Awareness of hepatitis C virus infection among pregnant women in Nigeria is low and those aware are positively influenced by young age and high educational level. The prevalence of hepatitis C virus infection is high and provides preliminary evidence to justify antenatal routine screening.

Pregnant women's hepatitis B vaccination coverage in Nigeria: a national pilot cross-sectional study.

OBJECTIVE: To determine the hepatitis B vaccination coverage, full-dose (⩾3) coverage and the associated factors affecting uptake among pregnant women. METHODS: This was a cross-sectional study among pregnant women attending antenatal care in six tertiary hospitals across all the geopolitical zones of Nigeria. Pregnant women who consented to the study completed screening questions about their hepatitis B vaccination status and coverage. The main outcome measures were hepatitis B vaccination coverage rate, dose, and factors affecting uptake. Bivariate analysis was performed by the chi-square test and conditional logistic regression analysis was used to determine variables associated with uptake of the vaccination. Odds ratios (ORs) and adjusted odds ratios (aORs) were calculated and statistical significance was accepted when p-value was < 0.05. RESULTS: Of 159 pregnant women who completed the interview questions, 21 [13.2%, 95% confidence interval (CI) 7.9-18.5%] were vaccinated for hepatitis B for one to three doses. The numbers of doses received were: three doses (8/159, 5.0%), two doses (5/159, 3.1%), and one dose (8/159, 5.0%). The reasons for non-uptake of vaccination included: lack of awareness of the vaccine 83/138 (60.1%), inadequate access to vaccine 11/138 (8.0%), and positivity to hepatitis B virus 10/138 (7.2%). The uptake of hepatitis B vaccination was significantly affected by the level of education (OR 0.284, 95% CI 0.08-1.01, p = 0.041), but in multivariable logistic regression, adjusted for confounders, the association between hepatitis B vaccination and participants' level of education (aOR 3.09; 95% CI 0.95-10.16; p = 0.061) did not remain significant. CONCLUSIONS: In Nigeria, the national hepatitis B vaccination coverage among pregnant women appears poor, with the full-dose coverage even poorer. The level of education was not positively associated with uptake of hepatitis B vaccination, while lack of awareness of the vaccine was the commonest reason for non-uptake.

Mother-to-child transmission of human immunodeficiency virus (HIV) among HIV-infected pregnant women on highly active anti-retroviral therapy with premature rupture of membranes at term.

PURPOSE: To determine mother-to-child transmission (MTCT) rate and associated risk factors of human immune-deficiency virus (HIV) among HIV-infected pregnant women with term premature rupture of membranes (PROM) in comparison with those without PROM at term. MATERIALS AND METHODS: All optimally managed HIV-positive pregnant women of Nnamdi Azikiwe University Teaching Hospital, on highly active anti-retroviral therapy (HAART) who had PROM at term were enrolled. Maternal HIV-1 viral load was not assessed. Follow up was for a minimum of 18 months for evidence of HIV infection. RESULTS: Of the 121 women with PROM at term, 46 (38.0%) were HIV sero-positive, 22/46 (47.8%) of which had their babies followed up till 18 months. The mean latency period was 10.5 ± 5.3 h in PROM group. Apart from duration of PROM (OR = 0.01; 95%CI = 0.00-0.13; p < 0.001), there were no differences in risk factors seen between cases and controls (p > 0.05). Of the 22 (47.8%) babies followed-up in the PROM group and 13 in non-PROM group, none tested positive to HIV, given an MTCT rate of 0%. CONCLUSIONS: MTCT rate was 0% following term PROM and in women without PROM. Since maternal HIV-1 viral load was not assessed, we need to be critical while interpreting the findings.

Knowledge and attitude of donating and using cord blood for transfusion among patients attending Nnamdi Azikiwe University Teaching Hospital, Nnewi, South East Nigeria.

BACKGROUND: Allogeneic blood for transfusion is in short supply in most parts of the developing world. Cord blood for transfusion can be a significant source of blood supply to our health institutions. AIMS: This study aims to investigate the knowledge and attitude to the donation and use of umbilical cord blood (UCB) for transfusion among the patients receiving services in a tertiary health institution in South-East Nigeria. MATERIALS AND METHODS: This was a cross-sectional study; an anonymous structured questionnaire was used. A total of 549 consenting patients randomly selected from the antenatal, postnatal, sickle cell clinics, and wards were the subjects. Statistical analysis of the data was done using SPSS version 20.0. RESULTS: The mean age of the participants was 31.9 ± 9.5 years. The majority were females (77.2%), married (86.4%). About 26.2% of the respondents were willing to accept UCB for transfusion to them or their child. Following counseling, the acceptance rate increased to 71.5%. Most of the respondents (80.0%) were willing to donate the UCB of their baby; or be tested for HIV (93.3%), if necessary. Educational level was significantly associated with knowledge of UCB. After logistic regression, occupation, and gender were significantly associated with acceptance of UCB for transfusion. Up to 52% belonged to low income family background, approximately 150 US dollars monthly family income (50,000 naira). CONCLUSION: The knowledge and acceptance of UCB for transfusion are low in our environment. However, proper counseling and public enlightenment could change this attitude.

Changes in breastfeeding and nutritional status of Nigerian children between 1990 and 2008, and variations by region, area of residence and maternal education and occupation.

BACKGROUND: Inadequate breastfeeding practices contribute to malnutrition in young children. AIMS AND OBJECTIVES: This study examined changes in breastfeeding practices and the nutritional status of children (0-35 months, n = 37154) using data from the nationally-representative Nigerian Demographic and Health Surveys for 1990-2008. METHODS: The study estimated the relative changes in the proportion of children meeting recommended breastfeeding practices and the anthropometric indices of the children during the study period, by region, place of residence, maternal education and maternal occupation. RESULTS: In each study year, over 97% of the children were ever breastfed. The proportion of infants breastfed within 1 hour and 1 day of birth increased from 34% to 45.8%, and from 63.8% to 82.3%, respectively. Overall, breastfeeding for ≥ 12 months changed from 88.9% to 95.2%, an increase of 7%; however, an increase of 14% was observed in the northern region (from 86.1% to 97.8%) while a decline of 7% was observed in the southern region (from 97.1% to 89.9%). Over the study period, the prevalence of all the assessed indicators of malnutrition (stunting, wasting and underweight) increased in the northern region while the southern region experienced a decline in all except severe wasting. In both urban and rural areas, stunting and wasting increased, while underweight declined. Children of non-formally educated and unemployed mothers were more malnourished in all the study years. CONCLUSION: Improvement in some breastfeeding practices did not result in improvement in the nutritional status of Nigerian children during 1990-2008, particularly in northern Nigeria and among socially disadvantaged mothers. Improving maternal education and employment, and integrating messages on techniques and benefits of optimal infant feeding with other maternal and child healthcare services could be beneficial.
