Perception, interpretation, and implication of non-penile vaginal sex among young adults in tertiary institutions in Northcentral Nigeria.

Young adults in tertiary institutions engage in different sexual behaviours including penetrative and non-penetrative sex. This study explored young adults' perceptions, interpretations and implications for engaging in non-penile-vaginal sex (NPVS) in tertiary institutions of Plateau state, in the north-central Zone. An exploratory qualitative research approach was adopted. Eight (8) focus group discussions (FGDs) of singles and married males and females were conducted with seventy-nine (n=79) participants aged 18 - 30 years). Audio files were transcribed, coded, and managed using NVivo 12 software. Thematic analysis was applied to present themes and a description of key findings. Four (4) themes emerged. All groups acknowledged sexual satisfaction and improved intimacy as benefits of NPVS. The sexual orientation of people who partake in NPVS are often misinterpreted. Young adults involved in NPVS face rejection and stigmatization. Lastly, the sexual orientation misinterpretation, rejection and stigma of those who engage in NPVS is likely to be a result of the general believe that Nigeria is conservative in sociocultural values and expression.

Les jeunes adultes des établissements d'enseignement supérieur adoptent différents comportements sexuels, notamment des relations sexuelles avec et sans pénétration. Cette étude a exploré les perceptions, les interprétations et les implications des jeunes adultes concernant la pratique de relations sexuelles non péniennes-vaginales (NPVS) dans les établissements d'enseignement supérieur de l'État du Plateau, dans la zone centre-nord. Une approche de recherche exploratoire qualitative a été adoptée. Huit (8) discussions de groupe (FGD) d'hommes et de femmes célibataires et mariés ont été menées avec soixante-dix-neuf (n = 79) participants âgés de 18 à 30 ans). Les fichiers audio ont été transcrits, codés et gérés à l'aide du logiciel NVivo 12. L'analyse thématique a été appliquée aux thèmes présentés et à une description des principales conclusions. Quatre (4) thèmes ont émergé. Tous les groupes ont reconnu la satisfaction sexuelle et l'amélioration de l'intimité comme avantages du NPVS. L'orientation sexuelle des personnes qui participent aux NPVS est souvent mal interprétée. Les jeunes adultes impliqués dans les NPVS sont confrontés au rejet et à la stigmatisation. Enfin, l'interprétation erronée de l'orientation sexuelle, le rejet et la stigmatisation de ceux qui s'engagent dans les NPVS sont probablement le résultat de la croyance générale selon laquelle le Nigeria est conservateur en termes de valeurs et d'expression socioculturelles.

Neglected medium-term and long-term consequences of labour and childbirth: a systematic analysis of the burden, recommended practices, and a way forward.

Over the past three decades, substantial progress has been made in reducing maternal mortality worldwide. However, the historical focus on mortality reduction has been accompanied by comparative neglect of labour and birth complications that can emerge or persist months or years postnatally. This paper addresses these overlooked conditions, arguing that their absence from the global health agenda and national action plans has led to the misconception that they are uncommon or unimportant. The historical limitation of postnatal care services to the 6 weeks after birth is also a contributing factor. We reviewed epidemiological data on medium-term and long-term complications arising from labour and childbirth beyond 6 weeks, along with high-quality clinical guidelines for their prevention, identification, and treatment. We explore the complex interplay of human evolution, maternal physiology, and inherent predispositions that contribute to these complications. We offer actionable recommendations to change the current trajectories of these neglected conditions and help achieve the targets of Sustainable Development Goal 3. This paper is the third in a Series of four papers about maternal health in the perinatal period and beyond.

Validation of self-report of uterine fibroid diagnosis using a transvaginal ultrasound scan.

Self-report of uterine fibroids (UF) has been used for epidemiologic research in different environments. Given the dearth of studies on the epidemiology of UF in Sub-Saharan Africa (SSA), it is valuable to evaluate its performance as a potential tool for much needed research on this common neoplasm in SSA women. We conducted a cross-sectional study of self-report of UF compared with transvaginal ultrasound diagnosis (TVUS) among 486 women who are members of the African Collaborative Center for Microbiome and Genomics Research (ACCME) Study Cohort in central Nigeria. We used log-binomial regression models to compute the classification, sensitivity, specificity, and predictive values of self-report compared to TVUS, adjusted for significant covariates. The prevalence of UF on TVUS was 45.1% (219/486) compared to 5.4% (26/486) based on self-report of abdominal ultrasound scan and 7.2% (35/486) based on report of healthcare practitioner's diagnosis. Self-report correctly classified 39.5% of the women compared to TVUS in multivariable adjusted models. The multivariable adjusted sensitivity of self-report of healthcare worker diagnosis was 38.8%, specificity was 74.5%, positive predictive value (PPV) was 55.6%, and negative predictive value (NPV) was 59.8%. For self-reported abdominal ultrasound diagnosis, the multivariable adjusted sensitivity was 40.6%, specificity was 75.3%, PPV was 57.4%, and NPV was 60.6%. Self-report significantly underestimates the prevalence of UF and is not accurate enough for epidemiological research on UF. Future studies of UF should use population-based designs and more accurate diagnostic tools such as TVUS.

Age-Specific Prevalence of Anal and Cervical Human Papillomavirus Infection and High-Grade Lesions in 11 177 Women by Human Immunodeficiency Virus Status: A Collaborative Pooled Analysis of 26 Studies.

BACKGROUND: Age-specific data on anal, and corresponding cervical, human papillomavirus (HPV) infection are needed to inform female anal cancer prevention. METHODS: We centrally reanalyzed individual-level data from 26 studies reporting HPV prevalence in paired anal and cervical samples by human immunodeficiency virus (HIV) status and age. For women with HIV (WWH) with anal high-grade squamous intraepithelial lesions or worse (HSIL+), we also investigated concurrent cervical cytopathology. RESULTS: In HIV-negative women, HPV16 prevalence decreased significantly with age, both at anus (4.3% at 15-24 years to 1.0% at ≥55 years; ptrend = 0.0026) and cervix (7.4% to 1.7%; ptrend < 0.0001). In WWH, HPV16 prevalence decreased with age at cervix (18.3% to 7.2%; ptrend = 0.0035) but not anus (11.5% to 13.9%; ptrend = 0.5412). Given anal HPV16 positivity, concurrent cervical HPV16 positivity also decreased with age, both in HIV-negative women (ptrend = 0.0005) and WWH (ptrend = 0.0166). Among 48 WWH with HPV16-positive anal HSIL+, 27 (56%) were cervical high-risk HPV-positive, including 8 with cervical HPV16, and 5 were cervical HSIL+. CONCLUSIONS: Age-specific shifts in HPV16 prevalence from cervix to anus suggest that HPV infections in the anus persist longer, or occur later in life, than in the cervix, particularly in WWH. This is an important consideration when assessing the utility of cervical screening results to stratify anal cancer risk.

Heterosexual Oral and Anal Sex: Perceptions, Terminologies, and Attitudes of Younger and Older Adults in Ibadan, Nigeria.

Although heterosexual oral and anal sexual behaviors have been reported in sub-Saharan Africa, little is known about how they are understood and perceived, particularly, in West Africa. We undertook a qualitative exploration of local terminologies and sexual scripts associated with heterosexual oral and anal sex in preparation for a quantitative survey. We held focus group discussions (18) and interviews (44) with younger and middle-aged men and women from the general population and female sex workers (FSWs) in selected communities in Ibadan. Most participants had heard of oral and anal sex. Younger adults aged 18-25 years, particularly male participants and FSWs, appeared more informed than older adults in the general population. Sexually explicit movies were the most cited source of information. Oral and anal sexual behaviors were considered sensitive, with different local names, meanings, and interpretations. Participants advised against the use of slang terms in research. We identified six different scripts employed by participants in discussing oral and anal sex practices: protecting sexual relationship, financial reward, an alternative to vaginal sex, pleasure, male dominance and control, and risk, stigma, and disgust.

Ecological analysis of demographic-, nutritional- and housing-related factors associated with anaemia among women of reproductive age group in Nigeria.

INTRODUCTION: Anaemia remains a major public health concern, particularly, in sub-Saharan Africa (SSA), where it is one of the causes of maternal death. The most common cause of maternal anaemia is iron deficiency or malnutrition. This study examined the prevalence of and risk factors for anaemia among women that participated in the Nigerian Demographic Health Survey. METHOD: We used data of 14,454 women that participated in the 2018 Nigeria Demographic and Health Survey (NDHS). We extracted information such as demographic, social and housing, dietary characteristics and haemoglobin concentration. The descriptive statistic results, prevalence and 95% confidence interval (CIs) of anaemia with the selected respondents background characteristics were presented. The Poisson regression model with robust variance was used to assess the risk of anaemia among women of reproductive age. All analyses were weighted and adjusted for the complex survey design. Statistical significance was interpreted at p value < 0.05. RESULTS: Maternal status, body mass index, education, residence, religion, ethnicity, region and type of cooking fuel were all important determinants of anaemia. The prevalence of anaemia was high among pregnant women (61.8%; 95% CI: 58.5-65.0), adolescents (60.4%; 95% CI: 58.1-62.6), underweight women (62.6%; 95% CI: 59.5-65.5), women who had no formal education (64.1%; 95% CI: 62.2-66.0) and those who belonged to the poorest wealth quintile (65.8%; 95% CI: 63.1-68.4). Similarly, anaemia was high among women residing in rural areas (61.5%; 95% CI: 60.0-63.0), Muslims (59.9%; 95% CI: 58.1-61.6) and women with six or more children (62.1%; 95% CI: 60.0-64.1). The risk of anaemia were 2% less likely among women who took minimum adequate diet compared to those who do not. CONCLUSION: To date, this is the largest data on maternal anaemia in Nigeria. The study highlighted the high burden of maternal anaemia in the country and different risk factors (medical and social) that are associated with this medical condition among women of reproductive age. We recommend future longitudinal studies to test hypothesis in order to assess whether there is any causal relationship between identified risk factors and anaemia in this group of women.

Improving quality of surgical and anaesthesia care in sub-Saharan Africa: a systematic review of hospital-based quality improvement interventions.

OBJECTIVES: To systematically review existing literature on hospital-based quality improvement studies in sub-Saharan Africa that aim to improve surgical and anaesthesia care, capturing clinical, process and implementation outcomes in order to evaluate the impact of the intervention and implementation learning. DESIGN: We conducted a systematic literature review and narrative synthesis. SETTING: Literature on hospital-based quality improvement studies in sub-Saharan Africa reviewed until 31 December 2021. PARTICIPANTS: MEDLINE, EMBASE, Global Health, CINAHL, Web of Science databases and grey literature were searched. INTERVENTION: We extracted data on intervention characteristics and how the intervention was delivered and evaluated. PRIMARY AND SECONDARY OUTCOME MEASURES: Importantly, we assessed whether clinical, process and implementation outcomes were collected and separately categorised the outcomes under the Institute of Medicine quality domains. Risk of bias was not assessed. RESULTS: Of 1573 articles identified, 49 were included from 17/48 sub-Saharan African countries, 16 of which were low-income or lower middle-income countries. Almost two-thirds of the studies took place in East Africa (31/49, 63.2%). The most common intervention focus was reduction of surgical site infection (12/49, 24.5%) and use of a surgical safety checklist (14/49, 28.6%). Use of implementation and quality improvement science methods were rare. Over half the studies measured clinical outcomes (29/49, 59.2%), with the most commonly reported ones being perioperative mortality (13/29, 44.8%) and surgical site infection rate (14/29, 48.3%). Process and implementation outcomes were reported in over two thirds of the studies (34/49, 69.4% and 35, 71.4%, respectively). The most studied quality domain was safety (44/49, 89.8%), with efficiency (4/49, 8.2%) and equitability (2/49, 4.1%) the least studied domains. CONCLUSIONS: There are few hospital-based studies that focus on improving the quality of surgical and anaesthesia care in sub-Saharan Africa. Use of implementation and quality improvement methodologies remain low, and some quality domains are neglected. PROSPERO REGISTRATION NUMBER: CRD42019125570.

Factors associated with breast disorders detected by clinical breast examination during pregnancy and six months postpartum in Ibadan, South-western Nigeria.

Background: Breast disorders (BD) during pregnancy and postpartum cause anxiety and reduce women's quality of life. The study examined BD risk factors during pregnancy and six months after delivery. Methods: Women attending antenatal clinics at 26 weeks gestation were recruited. 1248 pregnant women were followed six months postpartum. During recruitment, a validated questionnaire was used to collect participant characteristics and risk factors. Palpable lumps, inflammation, persistent pain, and abnormal nipple discharge were classified breast disorders. Statistical analysis used multiple logistic and cox regression models at p<0.05. Results: Women with benign breast disease were more likely to develop BD (aOR = 2.63, 95% CI = 1.50-4.88). One pregnancy increases the risk of BD more than three times (aOR=0.52, 95%CI: 0.29-0.95). History of breast trauma (aHR=3.59, 95%CI: 1.40-9.17) and 3 miscarriages vs. none (aHR=2.23, 95%CI: 1.04-4.23) were also risk factors for BD. The second quartile of physical activity was associated with a lower risk of BD (aHR=0.35, 95%CI: 0.15-0.78). Conclusion: Women with breast trauma and miscarriage are more likely to develop breast disorders during pregnancy and six months after delivery. Our findings highlight the need for additional longitudinal research to validate these findings and plans for prevention and control. Keywords: Breast disorders, pregnancy, postpartum, predictors, longitudinal study.

Epidemiology of uterine fibroid in black African women: a systematic scoping review.

OBJECTIVE: Studies, mainly from high-income countries, suggest that there are ethnic and racial variations in prevalence of uterine fibroids (UF). However, there have been few studies of the epidemiology of UF in sub-Saharan Africa (SSA). We reviewed published articles on the epidemiology of UF in SSA. DESIGN: This was a scoping review of literature. SETTINGS: We searched three databases (PubMed, African Wide Information (EBSCO) and African Journals OnLine (AJOL)). The search for eligible articles was conducted between December 2019 and January 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: To describe the reported prevalence/incidence of, and risk factors for UF in SSA. RESULTS: Of the 1052 articles retrieved, 9 met the inclusion criteria for review. The articles were from Nigeria (4/9), Ghana (2/9), Cameroon (1/9), Kenya (1/9) and South Africa (1/9). Two studies from pathology departments and three studies from radiology departments reported prevalence of UF. We did not find any study on the incidence or genomics of UF in SSA. Of the three studies that reported on the risk factors of UF, only one case-control study that was conducted using retrospective data of attendees at a gynaecological clinic conducted multivariable analysis. CONCLUSION: There is lack of robust epidemiological studies of the prevalence, incidence and risk factors of UF in SSA. There is urgent need to study epidemiological and genomics risk factors of UF in SSA because UF is the most common gynaecological neoplasm in this population where it is associated with significant morbidity and occasional, usually perioperative, mortality.

Utilization of Uterine and Umbilical Artery Doppler in the Second and Third Trimesters to Predict Adverse Pregnancy Outcomes: A Nigerian Experience.

Objective: To assess the utility of uterine and umbilical artery Doppler in the second and third-trimester in predicting adverse pregnancy outcomes. Methodology: In a prospective longitudinal study, the demographic, clinical, Doppler ultrasound parameters of the uterine and umbilical arteries of 84 consecutive women attending the antenatal clinic at 22-24 weeks and 116 women at 30-34 weeks gestation and pregnancy outcomes were documented and analyzed. Results: Pregnant women with adverse pregnancy outcomes had significantly higher second-trimester mean uterine systolic/diastolic (S/D) ratio (p = 0.001), pulsatility index (PI; p = 0.003), umbilical artery S/D (p = 0.016), and resistivity index (RI; p = 0.041) as well as higher third-trimester uterine S/D and PI. While pregnancies with adverse fetal outcomes showed significantly higher uterine artery S/D and PI at the second trimester, third-trimester uterine showed higher S/D, RI, and PI and umbilical artery PI than in women with normal fetal outcomes. The combination of uterine PI and early diastolic notch were predictors of maternal outcomes and correctly predicted 73% (p < 0.001) in the second trimester. By the third trimester, the uterine PI alone was the best predictor and accurately predicted about 62% of maternal outcomes (p = 0.028). In addition, the second-trimester uterine S/D and early diastolic notch and uterine PI in the third trimester correctly predicted 79% and 78% of fetal outcomes, respectively. Conclusion: Among unselected pregnant women population, the second-trimester Doppler parameters are better predictors of maternal adverse pregnancy outcomes, while adverse fetal outcome prediction by uterine and umbilical Doppler at the second- and the third-trimester parameters are comparable.

Oral, genital and anal human papillomavirus infections among female sex workers in Ibadan, Nigeria.

BACKGROUND: There are limited data on the epidemiology of HPV in different anatomical sites of female sex workers (FSW). We investigated the prevalence and concordance of cervical, vulval, oral and anal HPV among FSW in Ibadan, Nigeria. METHODS: FSWs aged 18-45 years were enrolled in a cross-sectional survey. After interview and clinical examination, samples were collected from mouth, cervix, vulva and anus. HPV genotyping was done with Anyplex II 28HPV assay. Multivariable analyses were performed to explore associated risk factors and concordance of HPV infections across sites. RESULTS: In total, 315 FSWs participated in the study with a mean age of 30-6.5 years. The prevalence of any HPV infection was 88% in the vulva, 84% in the cervix, 75% in the anus and 24% in the oral cavity. HPV 35 was the most prevalent and concordant high-risk type in the four sites. The risk factors for HPV infection by anatomic site varied. CONCLUSION: This large study showed a high prevalence and concordance of HPV infections of cervical, vulval, oral and anal HPV among FSWs in Nigeria. The potential to acquire and transmit HPV is high in this population, and we highlighted the urgency to protect young women through HPV vaccination.

Prevalence and genotype specific concordance of oro-genital and anal human papillomavirus infections among sexually active Nigerian women.

BACKGROUND: Human papillomavirus (HPV) associated cancers are increasingly reported globally, including in sub-Saharan Africa (SSA). However, with the exception of cervical HPV infection, data from SSA on the epidemiology of oral and genital HPV infections are limited. This study assessed the prevalence and concordance of oro-genital and anal HPV genotype specific infections among women in the general population. METHODS: We conducted a cross-sectional study in sexually active women aged 18-45 years in Ibadan, Nigeria. After a face-to-face interview and clinical examination, oral, cervical, vulvar, and anal samples were collected from participants and tested by the Anyplex II 28 HPV assay. Descriptive and multivariable analyses were used to report prevalence and risk factors associated with HPV infections. RESULTS: The prevalence of any vulva, cervical, anal, and oral HPV infections was 68.0% (210/309), 59.7% (182/305), 56.8% (172/303), and 16.1% (14/286), respectively. There was an inverse relationship between age-group and HPV prevalence of HPV in all anatomic sites except for the oral HPV infections. HPV 35 was the most prevalent high-risk HPV genotype in the vulva, cervix and oral cavity. Associated risk factors for HPV infection in each of the anatomic sites were reported. Overall, 10.0% (31/310) women had concordance of any HPV type in the four anatomic sites. CONCLUSION: There was a high prevalence of oro-genital and anal HPV infections among sexually active Nigerian women, with concordance of HPV types in the cervix, vulva, anus and oral cavity. We advocate large longitudinal studies that will involve sampling of multiple anatomic sites and inclusion of other women in the community for better understanding of HPV epidemiology in this region.

Factors associated with the awareness of vaginal fistula among women of reproductive age: findings from the 2018 Nigerian demographic health cross-sectional survey.

INTRODUCTION: Involuntary leakage of urine and or stool per vaginam (vaginal fistula) after childbirth remains a public health challenge in Africa and South East Asia. To the best of our knowledge, there is no previous national data that examined the awareness of vaginal fistula among women in Nigeria. AIM: To determine the prevalence of awareness of urinary/faecal incontinence due to vaginal fistula, and the associated risk factors among women with no previous experience of incontinence. METHODS: We used a cross-sectional study, the 2018 Nigerian Demographic Health Survey, to analyse awareness of vaginal fistula among women with no previous leakage of urine or stool. The primary outcome was childbirth experience, and other variables were demographics, access to information and reproductive or sexual history. The descriptive, univariate and multivariable models were presented. RESULTS: Of 26 585 women interviewed, 50 (0.2%) who had experienced fistula were excluded from the risk factor analysis. The mean age of women with childbirth experience was 32.8±8.6 years, while that of women without childbirth experience was 20.3±6.2 years. The prevalence of vaginal fistula awareness was 52.0%. Factors associated with the awareness include the following: childbirth experience (adjusted OR (AOR)=1.14; 95% CI, 1.01 to 1.30); age of 20-24 years (AOR=1.36; 95% CI, 1.18 to 1.56) and older; currently working (AOR=1.35; 95% CI, 1.22 to 1.49) and ownership of a mobile phone (AOR=1.16; 95% CI, 1.05 to 1.27). Other associated factors include the following: having at least secondary education; wealth quintiles, ethnicity, regional location, religion, access to radio, newspaper and internet; age up to 17 years at first sex; history of previous termination of pregnancy and use of contraception. CONCLUSION: A significant number of young women with no childbirth experience had low level of awareness. We recommend vaginal fistula awareness programmes that will target women at risk of vaginal fistula and the inclusion of other useful questions to improve the quality of information in future surveys.

Modeling for Predictors of Knowledge Score on Etiology and Prevention Strategies for Cervical Cancer Among Women of Reproductive Age in Ibadan.

PURPOSE: Poor knowledge regarding cervical cancer in at-risk populations directly affects health-seeking behavior and is associated with high mortality among women with cervical cancer. This study aims to evaluate the knowledge of women regarding the causes, risk factors, and prevention strategies of cervical cancer. METHODS: A multistage cross-sectional study of 1,002 women of reproductive age (18-49 years) in Ibadan was conducted. Knowledge of cervical cancer risk causes and prevention strategies was assessed using 13 and 9 question items, respectively. The knowledge score was graded as 0 (no knowledge), 1-4 (poor knowledge), or ≥ 5 (good knowledge). The proportional or partial proportional odds model was used to fit 3 models using the forward stepwise selection. All analysis was performed using Stata 15.0 (Stata Corp, College Station, TX). RESULTS: The median age of participants was 29 years (interquartile range [IQR], 23-35 years). The median knowledge scores of participants on causes and prevention strategies of cervical cancer were 3 (IQR, 0-4) and 3 (IQR, 0-5), respectively. The assessment of knowledge on causes and prevention strategies for cervical cancer revealed that having multiple sexual partners and no previous opportunity for counseling on cervical cancer screening were factors associated with lower odds of knowledge. CONCLUSION: The knowledge of women about the risk factors, causes, and prevention strategies of cervical cancer was poor. It is worrisome that poor knowledge was common among women with potential demographic risk factors for cervical cancer. We recommend innovative community mobilization to improve women's knowledge of the risk factors associated with cervical cancer and prevention strategies.

Economic status, a salient motivator for medicalisation of FGM in sub-Saharan Africa: Myth or reality from 13 national demographic health surveys.

Female Genital Mutilation or Cutting (FGM) and its medicalisation remain a challenge in sub-Sahara African (SSA). Early identification of at-risk women might help in instituting focused counselling against FGM medicalisation. We hypothesised that the risk of medicalised FGM by girls/women is associated with socioeconomic status (SES) their household belongs. We used 2010-2019 Demographic and Health surveys data from 13 countries in SSA. We analysed information on 214,707 women (Level 1) nested within 7299 neighbourhoods (Level 2) from the 13 countries (Level 3). We fitted 5 multivariable binomial multilevel logistic regression models using the MLWin 3.03 module in Stata. The estimation algorithms adopted was the first order marginal quasi-likelihood linearisation using the iterative generalised least squares. The odds of FGM medicalisation increased with the wealth status of the household of the woman, with 29%, 45%- and 75%-times higher odds in the middle, richer and richest household wealth quintiles, respectively than those from the poorest households (p < 0.05). The more educated a woman and the better a woman's community SES was, the higher her odds of reporting medicalisation of FGM. Rural community was associated with higher odds of medicalised FGM than urban settings. Medicalised FGM is common among women from a high socioeconomic, educational background and rural settings of SSA. We recommend a culturally sensitive policy that will discourage perpetuation of FGM, particularly by healthcare providers. Future studies should focus on identifying drivers of FGM among the high social class families in the society in SSA.

Breast Cancer Knowledge Assessment of Health Workers in Ibadan, Southwest Nigeria.

PURPOSE: Breast cancer is the most common cancer among women, and in low- to middle-income countries late-stage diagnosis contributes to significant mortality. Previous research at the University College Hospital, a tertiary hospital in Ibadan, Nigeria, on social factors contributing to late diagnosis revealed that many patients received inappropriate initial treatment. METHODS: The level of breast cancer knowledge among health practitioners at various levels of the health system was assessed. We developed a tool tailored to local needs to assess knowledge of symptoms, risk factors, treatments, and cultural beliefs. The recruitment included doctors, nurses, and pharmacists in public hospitals, physicians and pharmacists in private practice, nurses and health care workers from primary health care centers, community birth attendants, and students in a health care field from state schools. RESULTS: A total of 1,061 questionnaires were distributed, and 725 providers responded (68%). Seventy-eight percent were female, and > 90% were Yoruba, the dominant local ethnic group. The majority were Christian, and 18% were Muslim. Median knowledge score was 31 out of 56, and the differences in scores between health care worker types were statistically significant (P < .001). Nearly 60% of the participants believed breast cancer is always deadly. More than 40% of participants believed that keeping money in the bra causes breast cancer, and approximately 10% believed that breast cancer is caused by a spiritual attack. CONCLUSION: Our questionnaire revealed that, even at the tertiary care level, significant gaps in knowledge exist, and knowledge of breast cancer is unacceptably low at the level of community providers. In addition to efforts aimed at strengthening health systems, greater knowledge among community health care workers has the potential to reduce delays in diagnosis for Nigerian patients with breast cancer.

Association between Knowledge of Sexually Transmitted Infections and Sources of the Previous Point of Care among Nigerians: Findings from Three National HIV and AIDS Reproductive Health Surveys.

Background. Adequate knowledge of sexually transmitted infections (STIs) is critical for effective control of disease. Health education/counselling at the point of care provides ample opportunities to improve knowledge of patient seeking treatment. There is no study from Nigeria that investigates association between sources of previous point of care of STI and quality of knowledge of people on STI. We hypothesised that previous treatment of STI will be associated with better knowledge of STI and HIV infection. Methods. Three consecutives nationally representative cross-sectional surveys on HIV and AIDS Reproductive Health in Nigeria, conducted in 2005, 2007, and 2012 were analysed. Outcome measures were knowledge of STI only, and a combined knowledge of STI and HIV transmission and prevention. We designed a knowledge scale of 14-item questions for STI and 41-item questions for STI and HIV. Logistic regression was used to identify risk factors at 5% significance level. Results. Knowledge of STI increased from 13.4% in 2005 to 15.0% in 2007 to 26.5% in 2012. Respondents that received treatment from pharmacy and patient medicine vendors had higher odds of good knowledge of STI than those who did not receive any treatment (aOR = 2.55) in 2005. In 2012, respondents treated at health facilities were over two times likely to have good knowledge of STI and HIV transmission and prevention (aOR = 2.35). STI positive individuals in the highest economic class were two times likely to have good knowledge of STI and HIV transmission and prevention than those in the lowest class. Conclusion. Participants that previously sought care from health facilities, pharmacy, and patient medicine vendors had better knowledge of STIs and HIV infection prevention and transmission than those who sought care from unorthodox sources. We recommend a national awareness creation on STI prevention including provision of information on safe point of care for STIs in Nigeria.

Robustness of zero-augmented models over generalized linear models in analysing fertility data in Nigeria.

OBJECTIVE: Fertility is a count data usually rightly skewed and exhibiting large number of zeros than the distributional assumption of the generalized linear models (GLMs). This study examined the robustness of zero-augmented models over GLMs to fit fertility data across regions in Nigeria. The 2013 Nigeria Demographic and Health Survey data were used. The fertility models fitted included: Poisson, negative binomial, zero-inflated Poisson, zero-inflated negative binomial, hurdle Poisson and hurdle negative binomial. Akaike Information Criteria (AIC) and Bayesian Information Criteria (BIC) were used to identify the model with best fit (α = 0.05). RESULTS: The percentage of zero count in the fertility responses were 21.3, 23.9, 31.1, 30.7, 37.6 and 42.4 in North West, North East, North Central, South West, South South and South East regions respectively. In all the six regions in Nigeria, the zero-augmented models were better than the generalized linear models except for North Central. Extensively, the zero-augmented negative binomial based models were of better fit than their Poisson based counterparts; or in rare cases maybe indistinguishable. However, specific family of zero-augmented model is recommended for each region in Nigeria.

Reported oral and anal sex among adolescents and adults reporting heterosexual sex in sub-Saharan Africa: a systematic review.

BACKGROUND: Oral and anal sexual behaviours are increasingly reported among adolescents and adults reporting heterosexual sex in peer-reviewed journals in high income countries, but less is known about these behaviours in low and middle-income countries, especially in sub-Saharan Africa. The aim of this systematic review is to describe the prevalence of, and motivations for, oral and anal sex among adolescents and adults reporting heterosexual sex in sub-Saharan Africa. METHODS: A systematic review of published articles that reported oral and or anal sex in sub-Saharan Africa was conducted from seven databases up to and including 30th August 2018. RESULTS: Of 13,592 articles, 103 met the inclusion criteria. The prevalence of reporting ever practising oral sex among adolescents, university students and a combined population of adolescents/adults ranged from 1.7-26.6%, 5.0-46.4% and 3.0-47.2% respectively. Similarly, prevalences of reported ever practising anal sex ranged from 6.4-12.4% among adolescents, 0.3-46.5% among university students and 4.3-37.8% amongst combined population of adolescents and adults. Higher prevalences of oral and anal sex were reported among populations at high-risk for sexually transmitted infections and HIV and university students and, in most studies, both behaviours were more commonly reported by males than females. Heterosexual oral and anal sexual acts were associated with some high-risk behaviours such as inconsistent condom use and multiple sexual partners. CONCLUSION: Reported oral and anal sex between men and women are prevalent behaviours in sub-Saharan Africa. Health professionals and policy makers should be aware of these behaviours and their potential associated health risks.

The association between sperm quality and asymptomatic chlamydial infection in infertile men at a private fertility clinic in Nigeria

BACKGROUND: Association between chlamydia trachomatis infection and male infertility is debated in literature. There is little or no information from Nigeria. The study aimed to determine the prevalence of chlamydial infection and its association with sperm quality parameters among a symptomatic men that present for infertility treatment in a Nigeria facility. METHODS: A cross-sectional study conducted at a private assisted conception clinic in Lagos, Nigeria among 138 men seeking infertility care. Seminal fluid analysis and IgG Chlamydial serology were performed for each participant. Data obtained were analysed using SPSS; p was significant at <0.05. RESULTS: Of the 138 men screened, 13.9% were Chlamydia-positive. Twenty-one per cent of clients who tested positive to Chlamydia had predominantly immotile sperm, compared with 10.2% without the infection; 26.3% with non-progressive motility had Chlamydia, compared with 2.8% men who were not infected. These differences were statistically significant (p = 0.001). More of those (57.9%) with Chlamydia (compared to 33.1% without) had significant leukocyte counts (p = 0.037). There were no statistically significant differences in sperm count and percent motility between serologically positive and negative men. CONCLUSION: Positive Chlamydia serology is associated with non-progressive motility and leukocytospermia in infertile Nigerian men
