Regional differences in the utilisation of antenatal care and skilled birth attendant services during the COVID-19 pandemic in Nigeria: an interrupted time series analysis.

INTRODUCTION: The COVID-19 pandemic has had a substantial negative impact on the utilisation of essential health services (EHS) globally, especially in resource-limited settings such as Nigeria. High maternal deaths associated with low access to and utilisation of EHS such as antenatal care (ANC) and skilled birth attendants (SBAs) remain a concern during the COVID-19 era. The study assessed the COVID-19 pandemic effects on ANC and SBA utilisation across regions in Nigeria. METHODS: Monthly data on ANC and SBA between January 2017 and July 2021 were obtained from the Federal Ministry of Health database. An interrupted time-series analysis, implemented using the Prophet model, was conducted to compare the regional variation of outcomes during the COVID-19 pandemic. Average percentage changes (PC) between the observed and predicted outcomes including their 95% CI were reported. RESULTS: From March 2020 to July 2021, the number of ANC visits was significantly lower than expected by a 16%-43% change in five of the six regions in Nigeria. The highest significant reduction was in North-West (PC=-43.4; 95% CI: -52.6 to -34.1) and the least in South-West (PC=-15.5; 95% CI: -24.8 to -6.1), with no significant change in the South-East. The number of deliveries by SBA was significantly lower than expected by a 18%-43% change in all the regions (p<0.01). North-East (PC=-43.3; 95% CI: -51.7 to -34.9) and South-West (PC=-18.3; 95% CI: -25.2 to -11.5), respectively, had the highest and the least decline in SBA utilisation. Overall, ANC and SBA patterns of change were relatively similar across the north-south divide though the change effect was considerably pronounced in the north. CONCLUSION: There was a substantial reduction in ANC and SBA utilisation due to the COVID-19 pandemic in Nigeria, especially in the northern regions. Targeted and contextually relevant interventions should be implemented to alleviate the impact of emergency response on access to EHS and promote access to care during the pandemic.

COVID-19 surveillance in Democratic Republic of Congo, Nigeria, Senegal and Uganda: strengths, weaknesses and key Lessons.

INTRODUCTION: As part of efforts to rapidly identify and care for individuals with COVID-19, trace and quarantine contacts, and monitor disease trends over time, most African countries implemented interventions to strengthen their existing disease surveillance systems. This research describes the strengths, weaknesses and lessons learnt from the COVID-19 surveillance strategies implemented in four African countries to inform the enhancement of surveillance systems for future epidemics on the continent. METHODS: The four countries namely the Democratic Republic of Congo (DRC), Nigeria, Senegal, and Uganda, were selected based on their variability in COVID-19 response and representation of Francophone and Anglophone countries. A mixed-methods observational study was conducted including desk review and key informant interviews, to document best practices, gaps, and innovations in surveillance at the national, sub-national, health facilities, and community levels, and these learnings were synthesized across the countries. RESULTS: Surveillance approaches across countries included - case investigation, contact tracing, community-based, laboratory-based sentinel, serological, telephone hotlines, and genomic sequencing surveillance. As the COVID-19 pandemic progressed, the health systems moved from aggressive testing and contact tracing to detect virus and triage individual contacts into quarantine and confirmed cases, isolation and clinical care. Surveillance, including case definitions, changed from contact tracing of all contacts of confirmed cases to only symptomatic contacts and travelers. All countries reported inadequate staffing, staff capacity gaps and lack of full integration of data sources. All four countries under study improved data management and surveillance capacity by training health workers and increasing resources for laboratories, but the disease burden was under-detected. Decentralizing surveillance to enable swifter implementation of targeted public health measures at the subnational level was a challenge. There were also gaps in genomic and postmortem surveillance including community level sero-prevalence studies, as well as digital technologies to provide more timely and accurate surveillance data. CONCLUSION: All the four countries demonstrated a prompt public health surveillance response and adopted similar approaches to surveillance with some adaptations as the pandemic progresses. There is need for investments to enhance surveillance approaches and systems including decentralizing surveillance to the subnational and community levels, strengthening capabilities for genomic surveillance and use of digital technologies, among others. Investing in health worker capacity, ensuring data quality and availability and improving ability to transmit surveillance data between and across multiple levels of the health care system is also critical. Countries need to take immediate action in strengthening their surveillance systems to better prepare for the next major disease outbreak and pandemic.

Predictors of intestinal parasite infection among HIV patients on antiretroviral therapy in Jos, Plateau State, Nigeria, 2016: a cross-sectional survey.

INTRODUCTION: intestinal parasitic infection has been reported as a cause of morbidity and mortality among HIV patients on antiretroviral therapy (ART) due to interruption in treatment of the defaulting HIV patients. This study aimed to determine the prevalence and possible causes of intestinal parasites among HIV patients on ART. METHODS: a survey involving 375 adult HIV/AIDS patients selected using a systematic random sampling technique was conducted in a Jos University Teaching hospital, Plateau State, Nigeria. Socio-demographic and clinical data was collected using semi-structured interviewer administered questionnaire and electronic dataset review. Fresh stool samples were collected from all participants for laboratory identification of intestinal parasites using formol-ether sedimentation and modified Ziehl-Neelsen techniques. Descriptive statistics, odds ratio and logistic regression model were computed at P ≤ 0.05. RESULTS: the mean age of the study participants was 41.6±9.3years. Majority 294 (78.4%) were females, 141 (37.6%) lived in the rural area, 50 (13.3%) respondents did not have toilets in their homes. Most 275 (73.3%) had ART adherence level of 95% and above. Prevalence of intestinal parasites was 28.5%. Females (aOR = 2.14, 95% CI=1.12 - 3.89) and participants with no toilet facilities (aOR = 2.0, 95% CI=1.03 - 3.94) were significantly more likely to have intestinal parasites. CONCLUSION: the prevalence of intestinal parasites was high among HIV patients. Gender and unavailability of toilet in homes were found to be predictors of having parasites. We recommend that HIV patients should be periodically screened for IPs during the follow-up clinic visits.

Recognition and reporting of neglected tropical diseases by primary health care workers in Ibadan, Nigeria.

INTRODUCTION: neglected tropical diseases (NTDs) are serious public health problem worldwide. Primary healthcare (PHC) workers are important in the prevention and control of these diseases. Accurate diagnosis and timely reporting are essential for effective public health response. The study assessed the knowledge of PHC workers on NTDs and identified factors influencing its recognition and reporting. METHODS: the study was a hospital based cross-sectional survey. A multistage sampling technique was used to select 327 healthcare workers from sixty-six PHC facilities in Ibadan, Oyo State, Nigeria. A semi-structured, self-administered questionnaire was used to elicit information on respondent´s socio-demographic characteristics, knowledge, recognition and reporting of NTDs. Data analysis were done using independent sample t-test, analysis of variance and logistic regression with p-value set at 0.05. RESULTS: one hundred and eighty seven (57.2%) respondents had good knowledge of NTDs. The NTDs most known were; Schistosomiasis (78%), Rabies (64.5%), and Onchocerciasis (57.2%). Urban healthcare workers had higher knowledge score on NTDs (p= 0.018). Young age (AOR= 3.40, CI= 1.20 -9.63), length of practice (AOR=4.65, CI= 1.20-18.09) and previous training on NTDs (AOR = 7.09, CI= 3.15 - 15.93) significantly predicted NTDs recognition, while availability of reporting forms (AOR= 3.17, CI=1.07 - 9.35), training on disease reporting (AOR= 3.41, CI= 11.17 - 9.92) and feedback on previous diseases reported (AOR= 4.12, CI= 1.32-12.80) were significant predictors of reporting NTDs. CONCLUSION: the healthcare workers knowledge on NTDs was inadequate. Periodic training and continued education on NTDs are recommended. PHC workers also require supportive supervision.

Domestic Violence and Sexual Assault Service Providers' Perspectives on Nigerian Immigrants' Domestic Violence Experiences.

We investigated 13 domestic violence (DV) and sexual assault agency directors' perspectives regarding Nigerian immigrants' experiences of violence, DV-related service needs, and best strategies for providing those needs. Directors across five U.S. states were surveyed. Descriptive analyses showed the most common DV types were controlling behavior and cultural/traditional. The most important DV support needs were informational, informal, and legal. Formal support from DV agencies, support groups, and law enforcement was rated the most helpful strategies. Participants wanted to learn more about Nigerian immigrants' DV experiences. Findings highlight implications for the development of Nigerian-specific DV services.

Prevalence of bovine tuberculosis in slaughtered cattle and factors associated with risk of disease transmission among cattle handlers at Oko-Oba Abattoir, Lagos, Nigeria.

BACKGROUND AND AIM: Bovine tuberculosis (bTB) is a zoonotic disease of major public health importance, especially in many developing countries, including Nigeria, where control measures are largely not applied, and the risks of human infection are high. This study was aimed at determining the current prevalence of bTB in slaughtered cattle and identifying factors associated with the risk of disease transmission among cattle handlers toward making informed control measures to limit human-animal interface disease transmission. MATERIALS AND METHODS: Serum samples at slaughter and lesions suggestive of bTB collected during postmortem examination of 187 slaughtered cattle at the Oko-Oba Abattoir, Agege, Lagos State, Nigeria, were subjected to lateral flow and Ziehl-Neelsen (ZN) techniques, respectively. Furthermore, a structured questionnaire was interviewer-administered to 156 cattle handlers to investigate associated exposure factors to bTB infection. Data were analyzed using bivariate and multivariate logistic regression. RESULTS: The prevalence of bTB in cattle was 25.7% and 7.0% by lateral flow technique and ZN, respectively. The seropositivity was highest in cattle with poor body condition (50.0%), then with good (36.4%) and fair (25.0%) body conditions. The questionnaire survey revealed that being in livestock handling business for >6 years (p=0.001), not knowing the mode of transmission (p=0.02) and ignoring TB lesions at slaughter (p=0.02) were exposure factors associated with increased risk of bTB infection among the cattle handlers. Further, multivariate analysis showed that those who spent more than 6 years in livestock handling were about 4 times (Adjusted odds ratio [AOR]=3.5; 95% confidence interval [CI]=1.1-7.6, p=0.01) more likely to be exposed to bTB infection than those with lesser years. Again, respondents who called the attention of meat inspectors on seeing lesions in animals were about 4 times less likely to be exposed to bTB infection than those who ignored it (AOR=0.3; CI=0.1-0.8, p=0.01). CONCLUSION: This study has reiterated the endemicity of bTB in cattle population in Nigeria, with the prevalence of 25.7% and 7.0% of bTB by lateral flow and ZN techniques, respectively. This portends potential risk for disease transmission at the human-animal interface, particularly at the abattoir setting. The study also identified important knowledge and practice gaps which would enable informed, all-inclusive, and well-directed programs for effective control of the disease in both human and cattle populations.

Factors associated with induced abortion among women of reproductive age attending selected health facilities in Addis Ababa, Ethiopia: a case control study.

BACKGROUND: There has been a significant reduction of abortion rates in high-income countries, while the rates remain unchanged in low- and middle-income countries. In Ethiopia, for example, the number of women of reproductive age seeking an induced abortion is increasing. However, there is limited information concerning the reasons why the occurrence of this procedure is increasing. Thus, this study aimed to identify factors associated with having induced abortion in Addis Ababa, Ethiopia. METHODS: An unmatched case-control study was conducted using a semi-structured, interviewer-administered questionnaire from October to December 2017. The cases were 147 women of reproductive age who underwent abortion in a health facility or presented with complications due to induced abortion conducted outside the health facility. The controls were 295 women who came for antenatal care and who reported never having had an induced abortion. The cases were selected by consecutive sampling from nine health facilities, whereas the controls were selected by systematic sampling from the same health facilities. Bivariate and multivariate logistic regression models were employed using STATA version 14 to identify factors associated with induced abortion. RESULTS: The mean age of cases was 26.5 ± 5.7 years, while for the controls it was 28.1 ± 4.8 years. Being unmarried (AOR = 9.6; 95% CI: 1.5-61.7), having primary (AOR = 5.3; 95% CI: 1.5-18.3) and tertiary (AOR = 5.7; 95% CI: 1.6-21.1) education, earning monthly income 100-300 USD (AOR = 0.2; 95% CI: 0.1-0.4) and >  300 USD (AOR = 0.1; 95% CI: 0.0-0.2), initiating first intercourse between ages of 15 and 19 (AOR = 4.7; 95% CI: 1.4-15.6), marrying before the age of 18 (AOR = 2.9; 95% CI: 1.3-6.7), and having two children (AOR = 4.7; 95% CI: 1.8-12.7) were independent predictors of induced abortion. CONCLUSION: Family planning programs hoping to reduce the occurrence of induced abortion should specifically target unmarried women, low income, and those who have two children. The government should also work on preventing early marriage and providing sexual and reproductive health education to help adolescents delay age at first sexual experience.

Prevalence and correlates of intimate partner violence, before and during pregnancy among attendees of maternal and child health services, Enugu, Nigeria: mixed method approach, January 2015.

INTRODUCTION: Intimate Partner Violence (IPV) is an under-reported public health problem. This study determined the prevalence of IPV and types of IPV, complications and factors associated with IPV among women accessing health services. METHODS: we conducted a cross-sectional survey of 702 women accessing maternal and child health services in Enugu State, Nigeria using multi-stage sampling technique. Quantitative data was collected using semi-structured questionnaire, qualitative data by key informant interview (KII). We analysed data using descriptive statistics, bivariate and multivariate logistic regression analysis. The level of statistical significance was set at p-value < 0.05. Qualitative data was analysed using thematic content analysis. RESULTS: mean age of respondents was 27.71 ± 5.14 years and 654 (93.2%) were married. Prevalence of IPV, a year before last pregnancy, was 307 (43.7%) and during last pregnancy was 261 (37.2%). Frequent involvement in physical fights with other men, controlling behaviour and younger aged partners (< 40 years) were independent predictors of IPV experience both before and during pregnancy. Independent predictors of IPV experience before and during pregnancy were younger aged partners (< 40 years). [Adjusted Odds Ratio AOR 1.72; 95% confidence interval (CI) = 1.17, 2.53], partner having controlling behaviour AOR 2.24; 95% C.I=1.51-3.32) and Partner's frequent involvement in physical fights (AOR 2.29; 95% C.I = 1.43-3.66). Having a male child and married/cohabiting were protective against violence. KII revealed poverty, lack of education and infidelity as common triggers of IPV. CONCLUSION: the prevalence of IPV and types of IPV was high and the predisposing factors of IPV in Enugu were multifactorial. Couple counselling sessions that focus on non-violence conflict resolution techniques is crucial to end IPV.

Trends in mortality at Federal Medical Centre, Owo, Ondo State, Nigeria 2006-2014.

INTRODUCTION: vital events registration is not accurately done in Nigeria. Hence, mortality data is often not available. Health facility-based data can provide useful information on the trends in mortality of a population. This study describes the trend of deaths in a tertiary health facility. METHODS: a retrospective review of the medical records of all patients that died in the Federal Medical Centre, Owo, Ondo State, Nigeria from 2006 to 2014 was conducted. Data extracted from the records included age, sex, primary cause of death and date of admission and death. Frequencies were done and the median age of male and female deaths were compared using Mann-Whitney U test. RESULTS: a total of 1,326 deaths occurred in the hospital. The median age at death was 46 years (range: 0-110), median age was 49 years in males and 43 years in females (p = 0.025). One fifth (20.9%) of deaths was in infants. The median length of hospital stay was 4 days (range: 0-277). The highest proportion of death (16.4%) was in 2009 and on Wednesdays (15.9%). More deaths occurred in January (11.5%) and (10.3%) in February than in other months. The leading cause of communicable disease death in age 1 and above were HIV (15.2%) and TB (2.5%). Birth asphyxia (39.3%) and low birth weight (46%) were the commonest cause of death in infants. CONCLUSION: over the years the leading causes of mortality were preventable. Infant mortality remains a public health problem. Hospital mortality data could guide health decision making and interventions in Nigeria. Interventions to reduce death from communicable diseases and in infants are urgently recommended.

Response to an unusual outbreak in a high-risk situation.

In 2010, a series of lead poisoning outbreaks linked to artisanal gold processing killed at least 400 young children in Zamfara State in northwestern Nigeria. There were several efforts to respond to the outbreaks as they occurred. Subsequent recurrence of lead poisoning outbreaks within Zamfara and beyond suggested that there were no efforts to mitigate the outbreaks as recommended for disaster management. This case study, to be completed within 3 hours, is suitable for senior level public health officials and those training for such positions. It enables participants to review and apply epidemiological principles for managing disasters and suggest steps toward development of policy recommendations based on the context of environmental lead exposure. It will serve as a generic training module for managers/responders of other natural (floods, heat stroke) and man-made disasters (civil strife, conflict, insurgency) based on the general/standard principle of the complete disaster management cycle.

Contact tracing following outbreak of Ebola virus disease in urban settings in Nigeria.

An outbreak of Ebola virus disease occurred in Nigeria between July and September 2014. Contact tracing commenced in Lagos, and extended to Port Harcourt and Enugu as the outbreak continued to spread. A total of 899 contacts were traced. Contact tracing enhanced immediate identification of symptomatic contacts, some of whom eventually became cases. Contact tracing could be challenging in urban cities. However, use of electronic technology, adequate logistics, and highly skilled personnel enhanced the tracing of contacts to facilitate the successful containment of the outbreak. Nigeria was certified to be Ebola free on 21st October 2014. Ebola virus surveillance needs to be maintained to ensure the disease has been contained and to prevent future outbreaks. This case study aims to help trainees to review concepts, apply skills, and address challenges for contact tracing based on the experience of the Nigerian Field Epidemiology Training Network during the 2014 Ebola virus disease outbreak.

Setting research priorities for HIV/AIDS-related research in a post-graduate training programme: lessons learnt from the Nigeria Field Epidemiology and Laboratory Training Programme scientific workshop.

In Nigeria the current prevalence of HIV is 4.1% with over 3.5 million infected and estimated 1.5 million in need of anti-retroviral treatment. Epidemiological and implementation studies are necessary for monitoring and evaluation of interventions. To define research areas which can be addressed by participants of the Nigeria Field Epidemiology and Training Programme (NFELTP) a workshop was held in April 2013 in Abuja, Nigeria. Priority research areas were identified using criteria lists for ranking of the relevance of research questions. Based on a research matrix, NFELTP residents developed the aims and objectives, study design for HIV-related research proposals. This workshop was the first workshop held by the NFELTP to establish an inventory of research questions which can be addressed by the residents within their training period. This inventory will help to increase HIV/AIDS-related activities of NFELTP which are in accordance with research needs in Nigeria and PEPFAR objectives.

Prevalence of violence against pregnant women in Abeokuta, Nigeria.

AIM: To determine the prevalence of violence to pregnant women within 12 months prior to and during the current pregnancy. METHODS: Cross-sectional study of 534 pregnant women attending three secondary and one tertiary health facility in Abeokuta, Nigeria using semistructured interviewer-administered questionnaires. RESULTS: Prevalence of violence within 12 months prior to pregnancy was 14.2%. Polygamous union, low level of education in both woman and partner and consumption of alcohol by partners were significant (P < 0.05) risk factors of violence prior to pregnancy. Verbal abuse was the most common (66.2%) type of abuse. Others included flogging (10.8%), slaps (9.5%), threats of violence (6.8%) and forced sexual intercourse (2.7%). The perpetrators were often husbands (65.8%) and the parents (15.8%). Some 2.3% of pregnant women had experienced violence during current pregnancy. Low level of education was significantly (P < 0.05) associated with experiencing violence during pregnancy. Although almost 25% of the pregnancies were unplanned, this was not significantly associated with experiencing violence (P > 0.05). There were similarities in the perpetrators and forms of violence experienced before and during pregnancy, with partners being the most common perpetrators. CONCLUSION: Gender-based violence is common in our environment. Health-care providers should routinely screen for gender-based violence during antenatal visits in order to protect the health of both mother and child.
