Care-seeking for difficulties conceiving in sub-Saharan Africa: findings from population-based surveys in eight geographies.

STUDY QUESTION: What is the nature of women's care-seeking for difficulties conceiving in sub-Saharan Africa (SSA), including the correlates of seeking biomedical infertility care at a health facility? SUMMARY ANSWER: Care-seeking for difficulties getting pregnant was low, much of which involved traditional or religious sources of care, with evidence of sociodemographic disparities in receipt of biomedical care. WHAT IS KNOWN ALREADY: Nearly all research on infertility care-seeking patterns in SSA is limited to clinic-based studies among the minority of people in these settings who obtain facility-based services. In the absence of population-based data on infertility care-seeking, we are unable to determine the demand for services and disparities in the use of more effective biomedical sources of care. STUDY DESIGN, SIZE, DURATION: We used cross-sectional, population-based data from the Performance Monitoring for Action (PMA) female survey in eight geographies in SSA, including nationally representative data from Burkina Faso, Côte d'Ivoire, Kenya, and Uganda and regionally representative data from two provinces in the Democratic Republic of the Congo (DRC) (Kinshasa and Kongo Central) and two states in Nigeria (Kano and Lagos). We employed a multi-stage cluster random sampling design with probability proportional to size selection of clusters within each geography to produce representative samples of women aged 15-49. Samples ranged from 1144 in Kano, Nigeria, to 9489 in Kenya. PMA collected these data between November 2021 and December 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: We restricted the sample to women who had ever had sex, with analytic samples ranging from 854 in Kano to 8,059 in Kenya, then conducted descriptive and bivariable analyses to examine characteristics of those who sought care for difficulties getting pregnant. Among those who reported seeking care, we conducted bivariable and multivariable logistic regression analyses to determine factors associated with receipt of biomedical services from a health facility. All analyses were conducted separately by geography. MAIN RESULTS AND THE ROLE OF CHANCE: Our study found low levels of care-seeking for difficulties getting pregnant among sexually active women in eight geographies in SSA, ranging from 3.7% (Kenya) to 15.3% (Côte d'Ivoire). Of this, 51.8% (Burkina Faso) to 86.7% (Kinshasa) involved receipt of biomedical services in health facilities. While many factors were consistently associated with infertility care-seeking from any source across geographies, factors associated with receipt of biomedical care specifically were less pronounced. This may be a result of the highly limited sources of infertility services in SSA; thus, even privileged groups may struggle to obtain effective treatment for difficulties getting pregnant. However, we did observe disparities in biomedical care-seeking in our bivariable results in several geographies, with the wealthiest women, those with more education, and those residing in urban areas generally more likely to have sought biomedical care for difficulties getting pregnant. LIMITATIONS, REASONS FOR CAUTION: Our data lacked details on the nature of the services received and outcomes, and we do not have information on reasons why women chose the sources they did. Small samples of women who sought care limited our power to detect significant differences in care-seeking by women's characteristics in several geographies. WIDER IMPLICATIONS OF THE FINDINGS: Infertility and access to appropriate treatment are issues of reproductive health and human rights. While our results do not indicate to what extent use of non-biomedical sources of care is driven by preferences, cost, or lack of accessible services, it is clear from our results and existing literature that more needs to be done to ensure access to affordable, quality, cost-effective infertility services in SSA.

Prevalence of risk and factors associated with obstructive sleep apnea-hypopnea syndrome in an adult population in Kinshasa, Democratic Republic of Congo.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is an underdiagnosed and lesser known disease in sub-Saharan Africa. We believe that this is the first descriptive and analytical cross-sectional study in Kinshasa (from February 1 to October 31, 2021), which included respondents aged ≥18 years. The study aimed to determine the prevalence of the risk and factors associated with OSAHS. Each participant signed a free and informed consent. Statistical analyses were performed using XLStat 2020 and the Statistical Package for the Social Sciences version 24 for Windows. Odds ratios (ORs) were calculated to determine the degree of association between these variables and a high risk of OSAHS. The significance threshold was p < 0.05 and confidence interval (CI) at 95%. There were 4,162 participants, including 2,287 men (54.9%), with an mean (SD) age of 32 ± 12.6 years. The prevalence of OSAS risk was 17.4% and 7.9% for men and women, respectively. The associated risk factors were male sex (OR 4, 95% CI 3.20-5.54), hypertension (OR 6.7, 95% CI 4.87-9.30), age ≥60 years (OR 8.7, 95% CI 4.07-18.88), obesity/overweight (OR 1.94, 95% CI 1.13-3.78), and excessive daytime sleepiness (OR 2.63, 95% CI 2.05-3.56). The risk of OSAS in Kinshasa is high and it increases with age, male sex, obesity, and hypertension. The Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and male Gender (STOP-BANG) questionnaire is an easy-to-use tool for diagnostic orientation.

Abortion care availability, readiness, and access: linking population and health facility data in Kinshasa and Kongo Central, DRC.

BACKGROUND: The Democratic Republic of Congo (DRC) legalized abortion in 2018 to preserve health and pledged to provide quality postabortion care (PAC), yet little is known about the availability of abortion care services and if facilities are prepared to provide them; even less is known about the accessibility of these services. Using facility and population-based data in Kinshasa and Kongo Central, this study examined the availability of abortion services, readiness of facilities to provide them, and inequities in access. METHODS: Data on 153 facilities from the 2017-2018 DRC Demographic and Health Survey Service Provision Assessment (SPA) were used to examine signal functions and readiness of facilities to provide services across three abortion care domains (termination of pregnancy, basic treatment of abortion complications, and comprehensive treatment of abortion complications). To examine PAC and medication abortion provision before and after abortion decriminalization, we compared estimates from the 2017-2018 SPA facilities to estimates from the Performance Monitoring for Action (PMA) data collected in 2021 (n = 388). Lastly, we assessed proximity to PAC and medication abortion using PMA by geospatially linking facilities to representative samples of 2,326 and 1,856 women in Kinshasa and Kongo Central, respectively. RESULTS: Few facilities had all the signal functions under each abortion care domain, but most facilities had many of the signal functions: overall readiness scores were > 60% for each domain. In general, readiness was higher among referral facilities compared to primary facilities. The main barriers to facility readiness were stock shortages of misoprostol, injectable antibiotics, and contraception. Overall, provision of services was higher post-decriminalization. Access to facilities providing PAC and medication abortion was almost universal in urban Kinshasa, but patterns in rural Kongo Central showed a positive association with education attainment and wealth. CONCLUSION: Most facilities had many of the necessary signal functions to provide abortion services, but the majority experienced challenges with commodity availability. Inequities in accessibility of services also existed. Interventions that address supply chain challenges may improve facility readiness to provide abortion care services, and further efforts are needed to narrow the gap in accessibility, especially among poor women from rural settings.

Prevalence and correlates of reproductive coercion across ten sites: commonalities and divergence.

BACKGROUND: Reproductive coercion (RC) is a type of abuse where a partner asserts control over a woman's reproductive health trajectories. Recent research emphasizes that RC experiences may differ within and across low- and middle-income countries (LMICs), as compared to higher income contexts, given social pressures surrounding childbearing. To date, nationally representative surveys have lacked comprehensive measures for RC, leading to gaps in understanding its prevalence and risk factors. Across eight LMICs (10 sites), we aimed to (1) validate the RC Scale; (2) calculate prevalence of RC and specific behaviors; and (3) assess correlates of RC. METHODS: This analysis leverages cross-sectional Performance Monitoring for Action (PMA) data collected from November 2020 to May 2022. Analyses were limited to women in need of contraception (Burkina Faso n = 2767; Côte d'Ivoire n = 1561; Kongo Central, Democratic Republic of Congo (DRC) n = 830; Kinshasa, DRC n = 846; Kenya n = 4588; Kano, Nigeria n = 535; Lagos, Nigeria n = 612; Niger n = 1525; Rajasthan, India n = 3017; Uganda n = 2020). Past-year RC was assessed via five items adapted from the original RC Scale and previously tested in LMICs. Confirmatory factor analysis examined fit statistics by site. Per-item and overall prevalence were calculated. Site-specific bivariate and multivariable logistic regression examined RC correlates across the socioecological framework. RESULTS: Confirmatory factor analysis confirmed goodness of fit across all sites, with moderate internal consistency (alpha range: 0.66 Cote d'Ivoire-0.89 Kinshasa, DRC/Lagos, Nigeria). Past-year reported prevalence of RC was highest in Kongo Central, DRC (20.3%) and lowest in Niger (3.1%). Prevalence of individual items varied substantially by geography. Polygyny was the most common RC risk factor across six sites (adjusted odds ratio (aOR) range: 1.59-10.76). Increased partner education levels were protective in Kenya and Kano, Nigeria (aOR range: 0.23-0.67). Other assessed correlates differed by site. CONCLUSIONS: Understanding RC prevalence and behaviors is central to providing woman-centered reproductive care. RC was most strongly correlated with factors at the partner dyad level; future research is needed to unpack the relative contributions of relationship power dynamics versus cultural norms surrounding childbearing. Family planning services must recognize and respond to women's immediate needs to ensure RC does not alter reproductive trajectories, including vulnerability to unintended pregnancy.

Reproductive coercion (RC) is a type of abuse where a partner asserts control over a woman's reproductive health trajectories. While RC was conceptualized in the United States, recent research highlights that it may be prominent in other geographies, including sub-Saharan Africa. Existing national surveillance programs, including the Demographic and Health Surveys, have included a single item on RC beginning in 2018. Given the phased approach to Demographic and Health Survey roll-out, no studies have examined this single item across diverse contexts. Further, this single item may miss the range of abusive experiences women face when seeking to manage their fertility. Using annual national cross-sections in 10 diverse contexts (eight countries), we sought to: (1) validate a comprehensive RC measure; (2) calculate prevalence of RC and specific behaviors; (3) understand risk factors for RC across contexts. We found that the comprehensive RC measure performed well across sites. Prevalence of past-year RC was highest in the Kongo Central region of the Democratic Republic of Congo (20.3%) and lowest in Niger (3.1%). Polygynous marriage was associated with increased risk of RC across six sites, whereas increased partner education levels were protective against RC in two sites. Understanding the prevalence of RC within a given context and range of specific abusive behaviors, as well as risk profiles, can help alert local service providers to women's needs. A thorough understanding of commonalities and divergence of RC experiences and drivers across sites can help inform prevention and response programming to address RC and its health effects.

Prevalence of suspected dementia in a sample of adults living in Kinshasa-Democratic Republic of the Congo.

BACKGROUND: The prevalence of dementia in Sub-Saharan Africa, particularly in French-speaking countries, has received limited attention. This study investigates the prevalence and risk factors of suspected dementia in elderly adults in Kinshasa, Democratic Republic of the Congo (DRC). METHODS: A community-based sample of 355 individuals over 65 years old was selected using multistage probability sampling in Kinshasa. Participants were screened using the Community Screening Instrument for Dementia, Alzheimer's Questionnaire, Geriatric Depression Scale, Beck Anxiety Inventory, and Individual Fragility Questionnaire, followed by clinical interview and neurological examination. Suspected dementia diagnoses were made based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria including significant cognitive and functional impairments. Prevalence and odds ratios (ORs) with 95% confidence interval (CI) were calculated using, respectively, regression and logistic regression. RESULTS: Among 355 participants (mean age 74, SD = 7; 51% male), the crude prevalence of suspected dementia was 6.2% (9.0% in women and 3.8% in men). Female sex was a significant factor associated with suspected dementia [OR = 2.81, 95% CI (1.08-7.41)]. The prevalence of dementia increased with age (14.0% after 75 years and 23.1% after 85 years), with age being significantly associated with suspected dementia [OR = 5.42, 95% CI (2.86-10.28)]. Greater education was associated with a lower prevalence of suspected dementia [OR = 2.36, 95% CI (2.14-2.94), comparing those with ≥7.3 years of education to those with <7.3 years of education]. Other factors associated with the prevalence of suspected dementia included being widowed (OR = 1.66, 95% CI (1.05-2.61), being retired or semi-retired (OR = 3.25, 95% CI (1.50-7.03)], a diagnosis of anxiety [OR = 2.56, 95% CI (1.05-6.13)], and death of a spouse or a relative after age 65 [OR = 1.73, 95% CI (1.58-1.92)]. In contrast, depression [OR = 1.92, 95% CI (0.81-4.57)], hypertension [OR = 1.16, 95% CI (0.79-1.71)], body mass index (BMI) [OR = 1.06, 95% CI (0.40-2.79)], and alcohol consumption [OR = 0.83, 95% CI (0.19-3.58)] were not significantly associated with suspected dementia. CONCLUSIONS: This study found a prevalence of suspected dementia in Kinshasa/DRC similar to other developing countries and Central African countries. Reported risk factors provide information to identify high-risk individuals and develop preventive strategies in this setting.

Under-five mortality in the Democratic Republic of the Congo: secondary analyses of survey and conflict data by province.

Objective: To compare coverage of key child health policy indicators across provinces and to explore their association with under-five mortality and level of conflict in the Democratic Republic of the Congo. Methods: We made a secondary analysis of nationally representative data from 1380 health facilities and 20 792 households in 2017-2018. We analysed provincial-level data on coverage of 23 different indicators for improving common causes of childhood mortality, combined into mean scores for: newborn health, pneumonia, diarrhoea, malaria and safe environment. Using negative binomial regression we compared the scores with provincial-level under-five mortality. With binary logistic regression at the individual level we compared indicators (outcome) with living in a conflict-affected province (exposure). Findings: All grouped coverage scores demonstrated large ranges across the 26 provinces: newborn health: 20% to 61%; pneumonia: 26% to 86%; diarrhoea: 25% to 63%; malaria: 22% to 53%; and safe environment: 4% to 53%. The diarrhoea score demonstrated the strongest association with under-five mortality (adjusted coefficient: -0.026; 95% confidence interval: -0.045 to -0.007). Conflict-affected provinces had both the highest as well as the lowest mortality rates and indicator coverages. The odds of coverage were higher in conflict-affected provinces for 13 out of 23 indicators, whereas in provinces unaffected by conflict only one indicator had higher odds of coverage. Conclusion: Conflict alone is a poor predictor for child health. Ensuring that children in unaffected provinces are not neglected while addressing the needs of the most vulnerable in conflict settings is important. Prevent, protect and treat strategies for diarrhoeal disease could help improve equity in child survival.

Biennial surveillance of Plasmodium falciparum anti-malarial drug resistance markers in Democratic Republic of Congo, 2017 and 2019.

BACKGROUND: Because of the loss of chloroquine (CQ) effectiveness, the Democratic Republic of Congo (DRC)'s malaria treatment policy replaced CQ by sulfadoxine-pyrimethamine (SP) as first-line treatment of uncomplicated malaria in 2003, which in turn was replaced by artemisinin-based combination therapies (ACT) in 2005. The World Health Organization (WHO) recommends monitoring of anti-malarial drug resistance every 2 years. The study aimed to provide baseline data for biennial molecular surveillance of anti-malarial drug resistance by comparing data from a study conducted in 2019 to previously published data from a similar study conducted in 2017 in the DRC. METHODS: From July to November 2019, a cross-sectional study was conducted in ten sites which were previously selected for a similar study conducted in 2017 across the DRC. P. falciparum malaria was diagnosed by a rapid diagnostic test (RDT) or by microscopy and dried blood samples (DBS) were taken from patients who had a positive test. Segments of interest in pfcrt and pfk13 genes were amplified by conventional PCR before sequencing. RESULTS: Out of 1087 enrolled patients, 906 (83.3%) were PCR-confirmed for P. falciparum. Like in the 2017-study, none of the mutations known to be associated with Artemisinine (ART) resistance in Southeast Asia was detected. However, non-synonymous (NS) mutations with unknown functions were observed among which, A578S was detected in both 2017 and 2019-studies. The overall prevalence of pfcrt-K76T mutation that confers CQ-resistance was 22.7% in 2019-study compared to 28.5% in 2017-study (p-value = 0.069), but there was high variability between sites in the two studies. Like in 2017-study, the pfcrt 72-76 SVMNT haplotype associated with resistance to amodiaquine was not detected. CONCLUSION: The study reported, within 2 years, the non-presence of molecular markers currently known to be associated with resistance to ART and to AQ in P. falciparum isolated in the DRC. However, the presence of polymorphisms with as-yet unknown functions was observed, requiring further characterization. Moreover, an overall decrease in the prevalence of CQ-resistance marker was observed in the DRC, but this prevalence remained highly variable from region to region.

SARS-CoV2 infection in symptomatic patients: interest of serological tests and predictors of mortality: experience of DR Congo.

BACKGROUND: In symptomatic patients, the diagnostic approach of COVID-19 should be holistic. We aimed to evaluate the concordance between RT-PCR and serological tests (IgM/IgG), and identify the factors that best predict mortality (clinical stages or viral load). METHODS: The study included 242 patients referred to the University hospital of Kinshasa for suspected COVID-19, dyspnea or ARDS between June 1st, 2020 and August 02, 2020. Both antibody-SARS-CoV2 IgM/IgG and RT-PCR method were performed on the day of admission to hospital. The clinical stages were established according to the COVID-19 WHO classification. The viral load was expressed by the CtN2 (cycle threshold value of the nucleoproteins) and the CtE (envelope) genes of SARS- CoV-2 detected using GeneXpert. Kappa test and Cox regression were used as appropriate. RESULTS: The GeneXpert was positive in 74 patients (30.6%). Seventy two patients (29.8%) had positive IgM and 34 patients (14.0%) had positive IgG. The combination of RT-PCR and serological tests made it possible to treat 104 patients as having COVID-19, which represented an increase in cases of around 41% compared to the result based on GeneXpert alone. The comparison between the two tests has shown that 57 patients (23.5%) had discordant results. The Kappa coefficient was 0.451 (p < 0.001). We recorded 23 deaths (22.1%) among the COVID-19 patients vs 8 deaths (5.8%) among other patients. The severe-critical clinical stage increased the risk of mortality vs. mild-moderate stage (aHR: 26.8, p < 0.001). The values of CtE and CtN2 did not influence mortality significantly. CONCLUSION: In symptomatic patients, serological tests are a support which makes it possible to refer patients to the dedicated COVID-19 units and treat a greater number of COVID-19 patients. WHO Clinical classification seems to predict mortality better than SARS-Cov2 viral load.

Determinants of the use of contraceptive methods by adolescents in the Democratic Republic of the Congo: results of a cross-sectional survey.

BACKGROUND: Family planning (FP) is an effective strategy to prevent unintended pregnancies of adolescents. We aimed at identifying the socio-demographic factors underlying the low use of contraceptive methods by teenage girls in the Democratic Republic of the Congo (DRC). METHODS: A secondary analysis targeting teenage girls aged 15-19 was carried out on the Performance, Monitoring and Accountability project 2020 (PMA 2020) round 7 data, collected in Kinshasa and Kongo Central provinces. The dependent variable was the "use of contraceptive methods by sexually active teenage girls", calculated as the proportion of teenagers using modern, traditional or any contraceptive methods. Independent variables were: level of education, age, province, religion, marital status, number of children, knowledge of contraceptive methods and household income. Pearson's chi-square and logistic regression tests helped to measure the relationship between variables at the alpha significance cut point of 0.05. RESULTS: A total of 943 teenagers were interviewed; of which 22.6, 18.1 and 19.9% ​​used any contraceptive method respectively in Kinshasa, Kongo Central and overall. The use of modern contraceptive methods was estimated at 9.9, 13.4 and 12.0% respectively in Kinshasa, Kongo Central and overall. However, the use of traditional methods estimated at 8.0% overall, was higher in Kinshasa (12.7%) and lower (4.7%) in Kongo Central (p < .001). Some factors such as poor knowledge of contraceptive methods (aOR = 8.868; 95% CI, 2.997-26.240; p < .001); belonging to low-income households (aOR = 1.797; 95% CI, 1.099-2.940; p = .020); and living in Kongo central (aOR = 3.170; 95% CI, 1.974-5.091; p < .001) made teenagers more likely not to use any contraceptive method. CONCLUSION: The progress in the use of contraceptive methods by adolescent girls is not yet sufficient in the DRC. Socio-demographic factors, such as living in rural areas, poor knowledge of FP, and low-income are preventing teenagers from using FP methods. These findings highlight the need to fight against such barriers; and to make contraceptive services available, accessible, and affordable for teenagers.

The use of contraceptive methods remains low among adolescents aged 15 to 19 in the Democratic Republic of the Congo. However, family planning (FP) methods can help to prevent unintended pregnancies. This study aimed at identifying the socio-demographic factors that prevent teenage girls from using FP methods. We analyzed the data from the Performance, Monitoring and Accountability project (PMA 2020), seventh round, collected in Kinshasa and Kongo Central provinces. The use of contraceptive methods by sexually active adolescents was measured according to the level of education, age, province, religion, marital status, number of children, knowledge of contraceptive methods and household income. For the 943 adolescent girls interviewed, the use of any contraceptive method was calculated at 22.6, 18.1 and 19.9%, respectively in Kinshasa, Kongo Central and overall. The use of traditional methods was estimated at 8.0% overall, higher in Kinshasa (12.7%) and lower (4.7%) in Kongo Central. However, the use of modern contraceptive methods was estimated at 9.9, 13.4 and 12.0% respectively in Kinshasa, Kongo Central and overall. Poor knowledge of contraceptive methods; low-income and living in Kongo central province were the factors associated with the low use of any contraceptive method. In conclusion, the progress in the use of contraceptive methods by adolescent girls is not yet sufficient, due to some socio-demographic barriers. These results suggest to fight against such factors; and to make contraceptive services available, accessible, and affordable for teenagers.

As long as (I think) my husband agrees : role of perceived partner approval in contraceptive use among couples living in military camps in Kinshasa, DRC.

BACKGROUND: Male partner's approval is a key determinant of contraceptive use for women living in Sub-Saharan Africa and improving men's support and couple communication is a cornerstone of family planning programs. However, approval is often only measured through the women's perception of their partner's opinion. METHODS: This study conducted in Kinshasa compares contraceptive approval variables from matched male and female partners (n = 252 couples) to establish the frequency of (in)accurate perceptions by the woman, then test their association with modern contraceptive use. Additional regressions estimate individual and couple variables associated with (in)correct perceptions. RESULTS: Results confirm women are poorly aware of their partner's opinion but indicate that perceived approval or disapproval by the woman is a much stronger determinant of modern contraceptive use than her partner's actual opinion. Higher educational achievement from the woman is the strongest driver of misunderstanding her partner's approval. CONCLUSIONS: Women's perceptions of partner's approval are much stronger determinant of contraceptive use than the latter's actual opinion, and stereotyping men's opinion of family planning is a common error of appreciation. However, findings also suggest these misunderstandings might serve women's capacity to negotiate contraceptive use.

Research indicates that women living in Sub-Saharan Africa may not use contraceptive methods if their partner disapproves. However, there are methodological gaps in how this relation has been measured so far. For example, women are often the only ones asked whether their partner approves of contraception and surveys rarely assess how women know of their partner's disapproval and how strongly it has been communicated to them, nor do they ask said partner for his actual opinion on the matter.In this study we address some of those questions by interviewing men and women from married couples separately and comparing their opinion of family planning use. The research uses a population-based survey conducted among couples living in military camps in the capital city of the Democratic Republic Congo, Kinshasa.The results show that women overall are poorly aware of their partner's actual opinion, but act based on those perceptions, nonetheless. In particular, women whose husband disapproves of family planning but (falsely) perceive his approval have some of the highest odds in our cohort for contraceptive use. Conversely, women in a "false negative" scenario (husband approves but they perceive disapproval) are less likely to use modern contraception. Additional analysis indicates that this latter scenario is more common among women who are more educated than their partner, possibly because they are stereotyping his family planning desires. The findings and the discussion also raise the possibility that women may however benefit from ignoring their partners' true wishes in order to fulfill their own contraceptive choice.

Is Client Reporting on Contraceptive Use Always Accurate? Measuring Consistency and Change with a Multicountry Study.

The consistency of self-reported contraceptive use over short periods of time is important for understanding measurement reliability. We assess the consistency of and change in contraceptive use using longitudinal data from 9,390 urban female clients interviewed in DR Congo, India, Kenya, Niger, Nigeria, and Burkina Faso. Clients were interviewed in-person at a health facility and four to six months later by phone. We compared reports of contraceptive use at baseline with recall of baseline contraceptive use at follow-up. Agreement between these measures ranged from 59.1 percent in DR Congo to 84.4 percent in India. Change in both contraceptive method type (sterilization, long-acting, short-acting, nonuse) and use status (user, nonuser, discontinuer, adopter, switcher) was assessed comparing baseline to follow-up reports and retrospective versus current reports within the follow-up survey. More change in use was observed with panel reporting than within the cross section. The percent agreement between the two scenarios of change ranged from 64.8 percent in DR Congo to 84.5 percent in India, with cross-site variation. Consistently reported change in use status was highest for nonusers, followed by users, discontinuers, adopters, and switchers. Inconsistency in self-reported contraceptive use, even over four to six months, was nontrivial, indicating that studying measurement reliability of contraceptive use remains important.

Factors influencing client recall of contraceptive counseling at community-based distribution events in Kinshasa, Democratic Republic of the Congo.

BACKGROUND: Clients must recall information from contraceptive counseling sessions to properly use their chosen method. Client recall in community-based settings is challenging given the public nature of these events and the presence of many potential distractions. Understanding the factors that influence client recall during community-based distribution events can guide future training of providers to improve proper use of contraceptive methods and client satisfaction. METHODS: This cross-sectional study employed a convenience sample of 957 women ages 15-49 old who sought contraceptive services from community-based contraceptive distribution events in Kinshasa, Democratic Republic of the Congo, known as Lelo PF. Recall scores were developed by matching direct observations with client exit interviews. The association between recall and client characteristics, provider characteristics and an index for the quality of the provider-client interaction were tested using multivariate linear regression. RESULTS: The average recall score was 67.6%. Recall scores were higher among clients who accepted methods with simpler administration procedures, such as CycleBeads (81.3%), compared to methods requiring more medically advanced administration procedures, such as DMPA-SC (56.6%) and Implanon-NXT (62.1%). This relationship held even after controlling for amount of information each client received. Status as a first-time user was associated with a 5.8 percentage point decrease in recall score (p = 0.002). Time since the provider's initial family planning training and clients' perception of the provider-client interaction were associated with higher client recall scores. CONCLUSION: Results of this study suggest that to improve client recall at Lelo PF events, future provider training should focus on how to deliver clear, specific information to clients, making sure clients feel at ease during the counseling session, and treating clients with respect. First-time family planning users and clients who select methods with more medically advanced administration procedures may require extra attention during the consultation to ensure they are able understand and remember the information. Results suggest that providers who have been offering services longer may be more effective in conveying information in a way that clients can remember. Program managers should consider requesting input from experienced providers to improve training sessions.

Exploring association between MBL2 gene polymorphisms and the occurrence of clinical blackwater fever through a case-control study in Congolese children.

BACKGROUND: Blackwater fever (BWF), one of the most severe and life-threatening forms of falciparum malaria, is characterized by acute massive intravascular haemolysis, often leading to acute renal failure. Thus far, the genetics of the underlying susceptibility to develop BWF is not fully elucidated. Deficiency in the MBL protein, an important component of the innate immune system, has previously been suggested to be a susceptibility factor for the development of severe malaria. This study aimed to evaluate the association between MBL2 gene polymorphisms, known to affect the MBL protein level/activity, and the occurrence of BWF among Congolese children. METHODS: This is a case-control study. Cases were patients with BWF, whereas controls, matched for gender and age, had uncomplicated malaria (UM). Dried blood spot was collected for genotyping. RESULTS: A total of 129 children were screened, including 43 BWF and 86 UM. The common allele in BWF and UM was A, with a frequency of 76.7 and 61.0%, respectively (OR: 2.67 (0.87-829) and p = 0.079). The frequency of the C allele was 18.6 and 29.1% in BWF and UM groups, respectively, with p = 0.858. Not a single D allele was encountered. Genotype AA was at higher risk for BWF whereas genotypes A0 (AB and AC) were over-represented in UM group (OR: 0.21 (0.06-0.78)) with p = 0.019. Nine haplotypes were observed in this study: 3 high MBL expression haplotypes and 6 low MBL expression haplotype. One new haplotype HYPC was observed in this study. None of these haplotypes was significantly associated with BWF. CONCLUSION: This pilot study is a preliminary research on MBL2 gene and infectious diseases in DRC. The study results show a higher risk for BWF in AA. This suggests that future studies on BWF should further investigate the contribution of a strong immune response to the occurrence of BWF.

Feasibility and acceptability of using medical and nursing students to provide Implanon NXT at the community level in Kinshasa, Democratic Republic of Congo.

BACKGROUND: The use of implants has steadily increased in Kinshasa since 2013 but clinic-based access to this family planning method is limited due to distance and costs barriers. The objective of this study was to examine the feasibility and acceptability of providing Implanon NXT at the community level using medical and nursing students (M/N) as distributors, as part of a strategy to improve contraceptive uptake in the Democratic Republic of Congo. METHODS: A cohort of 531 women who chose to receive Implanon NXT from a M/N student during community-based campaign days participated in three rounds of a quantitative survey administered at the time of insertion of the method, and at 6 and 12 months later. We conducted descriptive analysis to assess the feasibility and acceptability of providing the method through M/N students in terms of method choice, user profiles, contraceptive history, experience with insertion and side effects, continuation / discontinuation of the method, and overall satisfaction with FP services as well as students' preparedness and capacity to safely offer the method, and their satisfaction with the experience.. RESULTS: The study demonstrated the feasibility of training students for community-based provision of Implanon NXT and 95% of them were satisfied with their experience. Acceptability of both the method and the service delivery strategy was high among participants, including among young and first-time contraceptive users. Out of the 441 women with a known outcome at 12 months, 92% still had Implanon NXT inserted, despite some of them reporting experiencing side effects. The vast majority (79%) would "strongly recommend" obtaining NXT from a M/N student if a friend wanted to avoid pregnancies. CONCLUSIONS: The provision of Implanon NXT at the community-level is a promising solution to address some of the barriers to accessing this method for women living in Kinshasa. However, strengthening pre-insertion counseling, particularly on expected side-effects and the possibility of early removal, is necessary to increase informed choice for the women and potentially limit method discontinuation.

Association between sickle cell anemia and alpha thalassemia reveals a high prevalence of the α3.7 triplication in congolese patients than in worldwide series.

BACKGROUND: Information about the association with alpha thalassemia in sickle cell patients is unknown in the Democratic Republic of Congo. There is very little data on the alpha thalassemia in patients suffering from sickle cell anemia in Central Africa, and their consequences on the clinical expression of the disease. METHODS: A cross-sectional study was conducted in 106 sickle cell patients living in the country's capital Kinshasa. The diagnosis of sickle cell anemia was confirmed with a molecular test using PCR-RFLP (restriction fragment length polymorphism) technique. The diagnosis of thalassemia was performed by the technique of multiplex ligation dependent probe amplification. RESULTS: The mean age of our patients was 22.4±13.6 years. The α3.7 heterozygous deletion, the α3.7 homozygous deletion and the α3.7 triplication were respectively encountered in 23.6%, 25.5% , and 11.3% of patients. Patients with normal αα/αα genotype represented 39.6% of the study population. The average of severe vaso-occlusive crises, the rates of blood transfusions per year, the rate of osteonecrosis, cholelithiasis and leg ulcers were significantly lower in the group of patients with α3.7 homozygous deletion and α3.7 triplication. CONCLUSION: The prevalence of α3.7 triplication was higher in sickle cell patients in the Democratic Republic of Congo than in worldwide series. The α3.7 triplication and α3.7 homozygous deletion were associated with less severe forms of the Sickle cell anemia in Congolese patients. These results showed the need to investigate systematically the alpha-globin gene mutations in sickle cell population in Central Africa.

Serum Soluble Transferrin Receptor Concentrations Are Elevated in Congolese Children with Glucose-6-Phosphate Dehydrogenase Variants, but Not Sickle Cell Variants or α-Thalassemia.

Background: Anemia is common in Congolese children, and inherited blood disorders may be a contributing cause. The presence of sickle cell variants, X-linked glucose-6-phosphate dehydrogenase (G6PD) deficiency and α-thalassemia, has been previously reported. G6PD A- deficiency is characterized by the co-inheritance of G6PD 376 and 202 variants and is common in sub-Saharan Africa.Objective: We aimed to measure the associations between inherited blood disorders and hemoglobin, ferritin, and soluble transferrin receptor (sTfR) concentrations in Congolese children.Methods: Venous blood was collected from 744 children aged 6-59 mo from 2 provinces. We measured biomarkers of nutritional and inflammation status and malaria. Pyrosequencing was used to detect sickle cell variants. Polymerase chain reaction was used to detect G6PD variants and α-thalassemia deletions.Results: Overall, 11% of children had a sickle cell variant, 19% of boys were G6PD A- hemizygotes, 12% and 10% of girls were G6PD A- hetero- or homozygotes, respectively, and 12% of children had α-thalassemia. Multivariable linear regression models (adjusted for age, province, altitude, malaria, and biomarkers of nutritional and inflammation status) showed that G6PD A- hemizygous boys and G6PD 376 homozygous girls had higher sTfR concentrations [geometric mean ratios (95% CIs): 1.20 (1.03, 1.39) and 1.25 (1.02, 1.53), respectively] than children with no G6PD variants. Hemoglobin and ferritin concentrations were not independently associated with any of the inherited blood disorder genotypes.Conclusions: We found that 2 G6PD variant genotypes were associated with elevated sTfR concentrations, which limits the accuracy of sTfR as a biomarker of iron status in this population.

Reverse epidemiology of elevated blood pressure among chronic hemodialysis black patients with stroke: a historical cohort study.

BACKGROUND: Stroke is the third leading cause of cardiovascular mortality in dialysis patients. The objective of this study was to assess the extent of stroke in chronic hemodialysis patients. METHODS: Historical cohort of patients enrolled in two hemodialysis (HD) centers from January 1, 2010 to December 31, 2011, including 191 patients (mean age 52 years, 68% men). Incidence curves and survival time analysis between the first day of HD and the end of the study were described by the Kaplan-Meier method. Independent stroke predictors were identified by multiple logistic regression analysis. P < 0.05 defined the level of statistical significance. RESULTS: 12 incident stroke were recorded during the study period, with 1622.1 person-months (PM), a stroke incidence rate of 7.4 cases per 1000 PM (95% CI = 7.35-7.44) at the point date. The incidence of stroke at 6 months, 12 months and 24 months was 9.8%, 11.9% and 13%, respectively. Only the absence of arterial hypertension (RR = 5.7, 95% CI: 1.52-21.42) emerged as an independent determinant of stroke. CONCLUSION: The high incidence of stroke in Kinshasa HD centers is partially explained by reverse epidemiology. Efforts must be made to understand this phenomenon in order to reduce its impact.

Clinical phenotypes and the biological parameters of Congolese patients suffering from sickle cell anemia: A first report from Central Africa.

BACKGROUND: The influence of phenotype on the clinical course and laboratory features of sickle cell anemia (SCA) is rarely described in sub-Saharan Africa. METHODS: A cross-sectional study was conducted in Kinshasa. A clinical phenotype score was built up. The following definitions were applied: asymptomatic clinical phenotype (ACP; score≤5), moderate clinical phenotype (MCP; score between 6 and 15), and severe clinical phenotype (SCP; score≥16). ANOVA test were used to compare differences among categorical variables. RESULTS: We have studied 140 patients. The mean body mass index (BMI) value of three groups was lower (<25 kg/m2 ) than the limit defining overweight. BMI of the subjects with ACP was significantly higher than those of other phenotypes (P<.05). Sickle cell patients with ACP have a high mean steady-state hemoglobin concentration compared to those with MCP and SCP (P<.001). A significant elevated baseline leukocyte count is associated with SCP (P<.001). Fetal Hemoglobin (HbF) was significantly higher in ACP. Significant elevation of alpha 1 and alpha 2 globulins in SCP were observed. CONCLUSION: In our study, fetal hemoglobin has an influence on the clinical severity and the biological parameters of SCA. The study provides data concerning the sickle cell anemia clinical and biological variability in our midst.

Albuminuria, serum antioxidant enzyme levels and markers of hemolysis and inflammation in steady state children with sickle cell anemia.

BACKGROUND: Oxidative stress is thought to be involved in the pathogenesis of microalbuminuria in Sickle cell anemia (SCA). Antioxidant enzymes such as glutathione peroxidase (GPx) and Cu-Zn superoxide dismutase (SOD) may play an important protective role. This study aimed to evaluate the association between albuminuria and these two antioxidant enzymes. METHODS: We consecutively recruited Steady state children aged between 2 and 18 years old with established diagnosis of homozygous SCA in two hospitals of Kinshasa/DR Congo. The relationship between Urinary Albumin Creatinine Ratio (UACR) and other variables of interest (age, systolic blood pressure, diastolic blood pressure, plasma GPx and Cu-Zn SOD, free plasmatic hemoglobin, LDH, indirect bilirubin, white blood cells (WBC), percentage of fetal hemoglobin, serum iron, ferritin, CRP) was analyzed by Bivariate correlation (Pearson's correlation coefficient). Microalbuminuria was defined by urine albumin/creatinine ratio between 30 and 299 mg/g. RESULTS: Seventy Steady state Black African children with SCA (56% boys; average age 9.9 ± 4.3 years; 53% receiving hydroxyurea) were selected. Prevalence of microalbuminuria was 11.8%. LDH (r = 0.260; p = 0.033) and WBC count (r = 0.264; p = 0.033) were positively correlated with UACR whereas GPx (- 0.328; p = 0.007) and Cu-Zn SOD (- 0.210; p = 0.091) were negatively correlated with UACR. CONCLUSIONS: Albuminuria is associated with decreased antioxidant capacity and increased levels of markers of hemolysis and inflammation. Therefore, strategies targeting the reduction of sickling and subsequent hemolysis, oxidative stress and inflammation could help preventing or at least delaying the progression of kidney disease in SCA children.
