High HIV prevalence among men who have sex with men in Nigeria: implications for combination prevention.

Background:This study provides population-based estimates of HIV prevalence and factors associated with HIV infection among men who have sex with men (MSM) in 3 large cities in Nigeria. We aimed to increase the knowledge base of the evolving HIV epidemic among MSM, highlight risk factors that may fuel the epidemic, and inform future HIV prevention packages. Methods:A total of 712 MSM, aged 18 years and older, living in Abuja, Ibadan, and Lagos were recruited using respondent-driven sampling. Participants completed a behavioral questionnaire and tested for HIV. Population-based estimates were obtained using RDSAT software. Factors associated with HIV infection were ascertained using multiple logistic regression adjusting for RDSAT individualized weights. Results:A high proportion of MSM reported high-risk behaviors, including unprotected anal sex with men (30–50%), unprotected vaginal sex with women (40%), bisexual behavior (30–45%), and never been tested for HIV (40–55%). The population-based estimates of HIV among MSM in the 3 cities were 34.9%, 11.3%, and 15.2%, respectively. In Abuja, HIV was significantly associated with unprotected sex and transactional sex. In Ibadan, HIV was significantly associated with unprotected sex and self-identified bisexual. In Lagos, HIV was significantly associated with the older age. Conclusions:HIV prevalence among MSM in the 3 cities was 4–10 times higher than the general population prevalence and was behaviorally linked. In response to a complex set of risks and disadvantages that put African MSM at a greater risk of HIV infection, future interventions targeting MSM should focus on a comprehensive approach that combines behavioral, biomedical, and structural interventions.

Comparison of audio computer assisted self-interview and face-to-face interview methods in eliciting HIV-related risks among men who have sex with men and men who inject drugs in Nigeria.

Introduction Face-to-face (FTF) interviews are the most frequently used means of obtaining information on sexual and drug injecting behaviours from men who have sex with men (MSM) and men who inject drugs (MWID). However, accurate information on these behaviours may be difficult to elicit because of sociocultural hostility towards these populations and the criminalization associated with these behaviours. Audio computer assisted self-interview (ACASI) is an interviewing technique that may mitigate social desirability bias in this context. Methods This study evaluated differences in the reporting of HIV-related risky behaviours by MSM and MWID using ACASI and FTF interviews. Between August and September 2010, 712 MSM and 328 MWID in Nigeria were randomized to either ACASI or FTF interview for completion of a behavioural survey that included questions on sensitive sexual and injecting risk behaviours. Data were analyzed separately for MSM and MWID. Logistic regression was run for each behaviour as a dependent variable to determine differences in reporting methods. Results MSM interviewed via ACASI reported significantly higher risky behaviours with both women (multiple female sexual partners 51% vs. 43%, p = 0.04; had unprotected anal sex with women 72% vs. 57%, p = 0.05) and men (multiple male sex partners 70% vs. 54%, p≤0.001) than through FTF. Additionally, they were more likely to self-identify as homosexual (AOR: 3.3, 95%CI:2.4–4.6) and report drug use in the past 12 months (AOR:40.0, 95%CI: 9.6–166.0). MWID interviewed with ACASI were more likely to report needle sharing (AOR:3.3, 95%CI:1.2–8.9) and re-use (AOR:2.2, 95%CI:1.2–3.9) in the past month and prior HIV testing (AOR:1.6, 95%CI 1.02–2.5). Conclusion The feasibility of using ACASI in studies and clinics targeting key populations in Nigeria must be explored to increase the likelihood of obtaining more accurate data on high risk behaviours to inform improved risk reduction strategies that reduce HIV transmission.

A profile on HIV prevalence and risk behaviors among injecting drug users in Nigeria: Should we be alarmed?

OBJECTIVE Injecting drug use is now recognized as a significant risk factor for HIV in sub-Saharan Africa. We evaluated prevalence and correlates of HIV among injecting drug users (IDUs) in Nigeria. METHODS A cross sectional design using respondent driven sampling was conducted in six states in 2010. Weighted HIV prevalence and injecting risk behaviors calculated using RDS analytic tool. Logistic regression was used to determine correlates of HIV infection, stratified by state. RESULTS Total numbers of IDUs ranged from 197 in Lagos to 273 in Cross River and Oyo states. HIV prevalence was highest in Federal Capital Territory (FCT) at 9.3%, Kaduna 5.8%, Oyo 5.1%, Kano 4.9%, CR 3.3% and Lagos 3.0%. Although >90% of participants were male, females had higher HIV prevalence in all states surveyed except FCT (range: 7.4% in CR to 37.7% in Kano). Logistic regression showed that females were significantly more likely to be HIV positive in Kano [OR=33.2, 95% CI: 6.8-160.4], Oyo [AOR=15.9, 95% CI: 3.69-68.51], Lagos [OR=15.5, 95% CI: 2.41-99.5] and Kaduna states [AOR=19.6, 95% CI: 4.4-87.6]. For injecting risk behavior, only receptive sharing was associated with HIV [AOR=7.6, 95% CI: 1.2-48.7] and [AOR=0.2, 95% CI: 0.04-0.92] in Oyo and Kaduna states respectively. CONCLUSIONS Considerable heterogeneity in the prevalence of HIV and associated risk behaviors exist among IDUs across Nigeria. Females had higher HIV prevalence among IDUs in five of six states, suggesting a need for targeted interventions for this hidden subgroup. Further research is needed to understand HIV transmission dynamics of IDUs in Nigeria. Community-based opioid substitution therapy and needle exchange programs should be implemented without delay.

Sexual risk behaviors and HIV among female sex workers in Nigeria.

Background:Female sex workers (FSWs) account for about 20% of new HIV infections in Nigeria. We estimated the change in HIV prevalence and sexual risk behaviors between 2 consecutive rounds of integrated biological and behavioral surveillance surveys (IBBSSs) and determined correlates of HIV transmission among FSWs. Methods:In 2007 and 2010, HIV prevalence and risk behavior data on brothel-based (BB) and non–brothel-based (NBB) FSWs from the integrated biological and behavioral surveillance survey were evaluated in 6 Nigerian states. Logistic regression was used to identify correlates of HIV infection. Results:A total of 2897 and 2963 FSWs were surveyed in 2007 and 2010, respectively. Overall HIV prevalence decreased in 2010 compared to 2007 (20% vs. 33%; P < 0.001), with similar magnitude of declines among BB-FSW (23% vs. 37%; P < 0.0001) and NBB-FSW (16% vs. 28%; P < 0.0001). Consistent condom use with boyfriends in the last 12 months was lower in 2010 compared to 2007 overall (23% vs. 25%; P = 0.02) and among BB-FSWs (17% vs. 23%; P < 0.01] while NBB-FSWs showed a marginal increase (30% vs. 27%; P = 0.08). FSWs residing in the Federal Capital Territory [adjusted odds ratio (AOR): 1.74 (1.34 − 2.27)] and Kano state [AOR: 2.07 (1.59 − 2.70)] were more likely to be HIV-positive while FSWs recruited in 2010 [AOR: 0.81 (0.77–0.85)] and those who had completed secondary education [AOR: 0.70 (0.60–0.80)] were less likely to be HIV-positive. Conclusions:Results suggest significant progress in reducing the burden of HIV among FSWs in Nigeria, although low condom use with boyfriends continued to be a potential bridge between FSWs and the general population. Venue-based prevention programs are needed to improve safer sex practices among BB-FSWs.

Benefits of using magnesium sulphate (MgSO4) for eclampsia management and maternal mortality reduction: lessons from Kano State in Northern Nigeria

BackgroundDespite clear emphasis through the Millennium Development Goals, the problem of high maternal mortality persists especially within low and middle income countries. Various studies report remarkably high maternal mortality rates in northern Nigeria, where maternal mortality rates exceed 1,000 deaths per 100,000 live births and eclampsia contributes approximately 40% of maternal deaths. Across Nigeria, diazepam is routinely used for the management of eclampsia. Prior to February 2008, diazepam was widely used for the management of eclampsia in Kano State (within northern Nigeria) with case fatality rate being over 20%. While magnesium sulphate (MgSO4) is recognized as the most effective drug for the management of eclampsia; this study aims to compare MgSO4 therapy with diazepam therapy in terms of case fatality rates and costs.FindingsThis retrospective study, including 1045 patients with eclampsia and pre-eclampsia during the years 2008 and 2009, reports a drop in case fatality rates from 20.9% (95% CI: 18.7, 23.2) to 2.3% (95% CI: 1.4, 3.2) among eclampsia patients following the MgSO4 intervention. The study observed no significant difference in the cost of using MgSO4 therapy compared to diazepam therapy.ConclusionsThe study found a remarkable reduction in case fatality rate due to eclampsia in those who received MgSO4 therapy with minimal increase in costs when compared to diazepam therapy. Concerted efforts should be focused on properly introducing MgSO4 into emergency obstetric protocols especially within developing countries to reduce maternal mortality and also impact on health system performance.

Success Providing Postpartum Intrauterine Devices in Private-Sector Health Care Facilities in Nigeria: Factors Associated With Uptake

41% of women delivering in the social franchise private facilities chose the postpartum IUD. Factors associated with acceptance included lower education, higher parity, and being single. Scale-up of postpartum IUD services in both public and private facilities has the potential to significantly increase use of long-acting reversible contraception in Nigeria. 41% of women delivering in the social franchise private facilities chose the postpartum IUD. Factors associated with acceptance included lower education, higher parity, and being single. Scale-up of postpartum IUD services in both public and private facilities has the potential to significantly increase use of long-acting reversible contraception in Nigeria. ABSTRACT Background: Use of modern contraceptive methods in Nigeria remained at 10% between 2008 and 2013 despite substantive investments in family planning services. Many women in their first postpartum year, in particular, have an unmet need for family planning. We evaluated use of postpartum intrauterine device (IUD) insertion and determined factors associated with its uptake in Nigeria. Methods: Data were collected between May 2014 and February 2015 from 11 private health care facilities in 6 southern Nigerian states. Women attending antenatal care in participating facilities were counseled on all available contraceptive methods including the postpartum IUD. Data were abstracted from participating facility records and evaluated using a cross-sectional analysis. Categorical variables were calculated as proportions while continuous variables were calculated as medians with the associated interquartile range (IQR). Multivariate logistic regression analysis was used to identify factors associated with uptake of the postpartum IUD while controlling for potential confounding factors, including age, educational attainment, marital status, parity, number of living children, and previous use of contraception. Results: During the study period, 728 women delivered in the 11 facilities. The median age was 28 years, and most women were educated (73% had completed at least the secondary level). The majority (96%) of the women reported they were married, and the median number of living children was 3 (IQR, 2–4). Uptake of the postpartum IUD was 41% (n = 300), with 8% (n = 25) of the acceptors experiencing expulsion of the IUD within 6 weeks post-insertion. After controlling for potential confounding factors, several characteristics were associated with greater likelihood of choosing the postpartum IUD, including lower education, having a higher number of living children, and being single. Women who had used contraceptives previously were less likely to choose the postpartum IUD than women who had not previously used contraception (adjusted odds ratio, 0.68; 95% confidence interval, 0.55 to 0.84). Conclusion: A high percentage (41%) of women delivering in private health care facilities in southern Nigeria accepted immediate postpartum IUD insertion. Scale-up of postpartum IUD services is a promising approach to increasing uptake of long-acting reversible contraceptives among women in Nigeria.

Evaluating the effect of HIV prevention strategies on uptake of HIV counselling and testing among male most-at-risk-populations in Nigeria; a cross-sectional analysis.

Objective The aim of this study was to evaluate the effects of three strategies in increasing uptake of HIV counselling and testing (HCT) among male most-at-risk-population (M-MARPs) using programmatic data. Design HIV prevention strategies were evaluated in a cross-sectional analysis. Methods Three HCT strategies were implemented between July 2009 and July 2012 among men who have sex with men (MSM) and people who inject drugs (PWIDs) in four states in Nigeria. The first strategy (S1), involved key opinion leaders (KOLs) who referred M-MARPs to health facilities for HCT. The second strategy (S2) involved KOLs referring M-MARPs to nearby mobile HCT teams while the third (S3) involved mobile M-MARPs peers conducting the HCT. χ2 statistics were used to test for differences in the distribution of categorical variables across groups while logistic regression was used to measure the effect of the different strategies while controlling for confounding factors. Results A total of 1988, 14 726 and 14 895 M-MARPs were offered HCT through S1, S2 and S3 strategies, respectively. Overall, S3 (13%) identified the highest proportion of HIV-positive M-MARPs compared with S1 (9%) and S2 (3%), p≤0.001. Also S3 (13%) identified the highest proportion of new HIV diagnosis compared with S1 (8%) and S2 (3%), respectively, p≤0.001. When controlled for age, marital status and occupation, MSM reached via S3 were 9 times (AOR: 9.21; 95% CI 5.57 to 15.23) more likely to uptake HCT when compared with S1 while PWIDs were 21 times (AOR: 20.90; 95% CI 17.33 to 25.21) more likely to uptake to HCT compared with those reached via S1. Conclusions Peer-led HCT delivered by S3 had the highest impact on the total number of M-MARPs reached and in identifying HIV-positive M-MARPs and new testers. Training M-MARPs peers to provide HCT is a high impact approach in delivering HCT to M-MARPs.

Attitudinal and Behavioral Factors Associated with Extramarital Sex Among Nigerian Men: Findings from a National Survey

ABSTRACT Using couple data from a national survey, this article examines couples characteristics associated with extramarital sex among Nigerian men. We found 15.4% of married men had extramarital sex in the past 12 months. Extramarital sex was significantly associated with mens attitude toward extramarital sex (OR = 1.7 [1.4–3.0]), early sexual debut (OR = 1.9 [1.6–2.3]), alcohol use (OR = 1.7 [1.4–2.1]), and intimate partner violence against wife (IPV) (OR = 1.4 [1.2–1.7]). Increased wifes education was associated with decreased husbands extramarital sex. Men living in rural areas and in the Central and Southern regions were also more likely to have extramarital sex. The findings suggest useful implications for HIV prevention programs in Nigeria. Interventions should focus on influencing social norms around protective behaviors for men to avoid risks associated with extramarital sex and IPV, helping men to change attitudes toward extramarital sex and IPV, and promoting delay in age at first sex among young men.

HIV Risk Perception and Risk Behaviors among Men Who Have Sex with Men in Nigeria

Background: Some studies have shown that greater perceived vulnerability to HIV is associated with less involvement in risk taking. We evaluated prevalence and correlates of HIV risk perception among men who have sex with men (MSM) in Nigeria. Methods: A cross sectional study using respondent driven sampling (RDS) was conducted in six Nigerian states in 2010. Weighted HIV risk perceptions were calculated using an RDS analytic tool. Logistic regression was used to determine correlates of HIV risk perception, stratified by state. Results: The total number of MSM ranged from 217 in Abuja to 314 in Cross River state. Median age ranged from 22 years in Cross River state to 26 years in Kano. HIV risk perception ranged from 10% in Cross River state to 58% in Kaduna state and was 38%, 44%, 19% and 20% in Kano, Lagos, Abuja and Oyo states respectively. Factors associated with HIV risk perception include purchasing sex (AOR: 3.11, 95% CI: 1.09-8.88) and never being tested for HIV (AOR = 0.34, 95% CI: 0.14 - 0.85] in Cross River; no comprehensive knowledge of HIV (AOR = 0.21, 95% CI: 0.05 - 0.90) and receptive anal partners (AOR = 10.07, 95% CI: 2.07 - 49.02) in Abuja; being older than 25 years (AOR = 0.16, 95% CI: 0.03 - 0.98) in Kano; no exposure to peer education in Kaduna (AOR = 0.08, 95% CI: 0.01 - 0.89); never being tested for HIV in Lagos (AOR = 0.11, 95% CI: 0.03 - 0.40) and Oyo state (AOR = 0.21, 95% CI: 0.06 - 0.80) and selling sex (AOR = 3.24, 95% CI: 1.00 - 10.61) in Oyo state. Conclusion: This study shows that HIV risk perception and comprehensive HIV knowledge are very low among MSM in Nigeria. Heterogeneity in associated factors suggests that targeted interventions are needed to increase HIV risk perception in the different states. The role of HIV counseling and testing in increasing risk perception needs further evaluation.

Obstetric knowledge of nurse-educators in Nigeria: Levels, regional differentials and their implications for maternal health delivery

Objective: To assess the knowledge of nurse-midwife educators on the major causes of maternal mortality in Nigeria. Setting: Schools of nursing and midwifery in Nigeria. Method: A total of 292 educators from 171 schools of nursing and midwifery in Nigeria were surveyed for their knowledge of the major causes of maternal mortality as a prelude to the design and implementation of a train-the-trainer intervention geared towards improved maternal health-care delivery. Results: There was paucity of knowledge across all major causes. Only 57.2% and 62.7% of educators could diagnose pre-eclampsia and severe pre-eclampsia, respectively. While 86% knew about magnesium sulphate (MgSO4) as the ‘gold standard’ for treating eclampsia, only 16.8% knew of calcium gluconate as an antidote to MgSO4 toxicity. Of the educators, 63.7% could not describe the components of active management of third stage of labour, while 29.5% were not aware of uterine atony as a cause of postpartum haemorrhage. Furthermore, 65.4% believed that misoprostol is the preferred oxytocic for hospital delivery. Other potentially harmful knowledge gaps were also found, such as 47.3% of the participants reporting that they would perform episiotomies on all primigravidae. Conclusion: Nurse/midwife educators in Nigeria are not as knowledgeable as previously thought, especially concerning the causes of maternal mortality. In order to scale up the quality of obstetric care, updated pre-service curricula should be implemented fully while in-service appraisal and continuing education should be introduced.
