PrEP Among Sub-Saharan African Diaspora Communities in Belgium - a Participatory Action Research Study

In Belgium, migrants from Sub-Saharan Africa (SSA) accounted for 45% of new heterosexual HIV infections in 2021, while only 1.5% of PrEP starters were of SSA descent. We explored the acceptance of PrEP and barriers towards PrEP uptake and use among SSA migrant and diaspora communities in Belgium using a participatory action research approach. Trained community researchers (CRs), involved in all phases of the study, co-designed and moderated group discussions (GDs) while simultaneously providing information on HIV and PrEP during workshops. Extensive summaries and field notes were analysed using reflexive thematic analysis. CRs were involved in data analysis, interpretation and reporting. We conducted seven GDs with 51 participants. We identified five major themes: (1) Participants had limited PrEP knowledge, which created feelings of surprise and annoyance about not being informed. This was partly explained by (2) the taboo and stigma that surrounds sexuality and HIV, which could shape PrEP acceptance. (3) Participants shared feelings of otherness due to experiences of racism and discrimination, also in relationship to HIV prevention. (4) PrEP was considered a high-threshold prevention tool, because of its perceived side-effects and its specialized service delivery. (5) Despite nuanced opinions about PrEP, all participants agreed that PrEP promotion should be mainstreamed, so everyone can make an informed decision. In conclusion, PrEP seemed acceptable among our participants. Our qualitative study provides insights into the intersecting barriers to accessing HIV services, showing that SSA diaspora communities are 'hardly reached' rather than 'hard to reach' by PrEP promotion messages.

Explanatory Models of (Mental) Health Among Sub-Saharan African Migrants in Belgium: A Qualitative Study of Healthcare Professionals' Perceptions and Practices

Culturally differing approaches to the distinction between physical and mental health contribute to cultural differences in explanatory models of what we call "mental" health in a Western context. For this reason, we use "(mental) health" in this study when referring to these models or differences in understanding. This interpretative, interview-based qualitative study focuses on Belgian mental health professionals' perceptions of the (mental) health explanatory models held by their patients of sub-Saharan African (SSA) descent. The study goals were threefold: first, to assess professionals' perceptions of the explanatory models of their patients of SSA descent; second, to examine how these perceptions influence treatment practices; and third, to investigate the role of the professionals' cultural backgrounds, comparing the results between professionals with and without an SSA background. Twenty-two in-depth interviews with mental health professionals were thematically analyzed, with ten of the participants of SSA descent. Results show that all professionals perceived differences between Western and SSA explanatory models of (mental) health. Causal beliefs were mentioned as the most important difference, including their influence on coping strategies and health-seeking behavior among patients of SSA descent. Professionals' perceptions and familiarity with SSA explanatory models of (mental) health affected their treatment practices. Language and conceptual interpretation difficulties were encountered less frequently by professionals of SSA descent. Those with a Western background applied "culturally sensitive" practices, while professionals of SSA descent implemented an integrated approach. These results contribute to ongoing discussions about what is considered "cultural competency."

Knowledge and perspectives of community members on risk assessment for stroke prevention using mobile health approaches in Nigeria

OBJECTIVES

To assess the knowledge of community dwelling adults on stroke risk and their willingness to use mobile health (mHealth) technology in assessing their stroke risk.

MATERIALS AND METHODS

A cross-sectional study was conducted among adults (≥18 years old) using survey questionnaires designed by neurologists and health promotion experts and administered by trained study staff. Logistic regression models were used to assess factors associated with receptivity toward knowing individual stroke risk score and willingness to use a mobile application (App) to assess stroke risk.

RESULTS

The survey was administered to 486 participants in Nigeria, with a mean age of 47.4 ± 15.5 years, comprising 53.5% females. Up to 84% of participants wanted to know their risk for developing stroke but only 29.6% of respondents had ever previously had their stroke risk assessed. Factors associated with willingness to know stroke risk were age [aOR (95% CI): 0.97 (0.95 - 0.99)], and Hausa tribe [16.68 (2.16 - 128.92)]. Up to 66% of participants wanted to know their immediate risk of stroke, compared with 6.6% and 2.1% who wanted to know their 5-year or 10-year future stroke risks respectively. Regarding locations, participants preferred stroke risk assessment to be performed at a health facility, at home by health professional, on their own using mHealth (stroke risk calculator application), or at communal gatherings (decreasing order). About 70% specifically wished to learn about their stroke risk via an mHealth application.

CONCLUSIONS

Community dwelling Nigerians wanted to know their immediate risk of stroke using digital platforms, such as a mobile phone stroke risk calculator application. Clinical trials are needed to assess the effectiveness of such a strategy for primary prevention of stroke in sub-Saharan African communities.

The use of condoms and other birth control methods among sexually active school-going adolescents in nine sub-Saharan African countries

BACKGROUND

Adolescents in sub-Saharan Africa still face sexual and reproductive health challenges. Contraceptives have been used to address these challenges. Despite efforts at national and global levels, contraceptive uptake among young people in Africa remains a challenge due to personal, societal, and health systems-based barriers. We estimated the prevalence and correlates of condom use and other birth control methods among sexually active school-going adolescents in nine sub-Saharan African (SSA) countries.

METHODS

We conducted a secondary analysis of the Global School-based Student Health Surveys (GSHS) datasets pooled from nine SSA countries. We included a sample of 27,504 school-going adolescents 11 years and younger and 18 years and older. We employed meta-analysis using a random-effects model to estimate the total prevalence of the use of condoms, other birth control methods other than a condom and any birth control method at last sexual intercourse. We conducted complex sample descriptive and logistic regression analyses to determine the characteristics and determinants of not using condoms and other birth control methods among sexually active school-going adolescents in nine sub-Saharan African countries, respectively.

RESULTS

More than half [n = 4430, 53.8% (43.9-63.8)], two-fifth [n = 3242, 39.5% (33.2-45.9) and two-thirds of adolescents [n = 4838, 65.6% (57.5-73.7)] of sexually active in school adolescents across the nine sub-Saharan African countries used condom, other birth control methods and any form birth control method during their last sexual intercourse, respectively. The non-use of condoms at last sex was associated with being younger (less than 16 years) [AOR = 1.48;95%CI: 1.12-1.94], early sexual debut [AOR = 1.81(1.47-2.22)], having two or more sexual partners [AOR = 1.30(1.06-1.58)] and no/minimal parental support [AOR = 1.54(1.17-2.03)]. The non-use of other birth control methods at last sex was associated with being male [AOR = 1.37 (1.09-1.73)], early sexual debut [AOR = 1.83(1.48-2.27) and having no parental support [AOR = 1.64(1.34-2.00)].

CONCLUSION

Contraceptive need among sexually active school adolescents in the nine sub-Saharan African countries is high. Such a need calls for the development of country-specific and or the review of existing school-based sexual health education and youth-friendly sexual and reproductive health interventions that target risky adolescents and promote adolescent-parent effective communication, connectedness and support.

Minimum acceptable diet intake and its associated factors among children age at 6-23 months in sub-Saharan Africa: a multilevel analysis of the sub-Saharan Africa demographic and health survey

Background

Only one in five children aged below 24 months in the low-income countries feed the minimum recommended diet, and significantly varied across socio-economic classes. Though sub-saharan Africa (SSA) shares the huge burden of children under nutrition, as to our search of literature there is limited evidence on the pooled magnitude and factors associated with minimum acceptable diet (MAD) intake among children aged 6 to 23 months in the region. This study aimed to assess the pooled magnitude and associated factors of MAD intake among children aged 6–23 months in SSA using recent 2010–2020 DHS data.

Methods

Demographic and Health Survey datasets of SSA countries were used for this study with a total of 78,542 weighted samples. The data were cleaned using MS excel and extracted and analyzed using STATA V.16 software. A multilevel binary logistic regression model was fitted. The adjusted odds ratio (AOR) with P-value < 0.05 was taken to declare statistical significance.

Results

The pooled magnitude of MAD intake among children aged 6–23 months in SSA was 9.89% [95%CI: 8.57, 11.21%] ranging from 3.10% in Guinea to 20.40% in Kenya. Individual level factors such as; secondary &above women educational status [AOR = 1.41; 95%CI; 1.29, 1.53], having employed women [AOR = 1.25;95%CI;1.17,1.33], having media exposure [AOR = 1.55;95%CI;1.45,1.66], richest household wealth [AOR = 1.93; 95%CI; 1.73, 2.15], plural birth [AOR = 0.68;95%CI; 0.56, 0.82] and breastfed child [AOR = 2.04; 95%CI; 1.89, 2.21], whereas, community level factor such as rural residence [AOR = 0.74; 95%CI; 0.69, 0.79] and living in upper middle income country [AOR = 1.62; [95%CI; 1.41,1.87] were significantly associated with MAD intake.

Conclusion and recommendations

Minimum acceptable diet intake in SSA is relatively low. Variables such as; secondary &above maternal education, having employed mother, exposure to media, richest wealth, breast feeding child, and upper middle income country have a significant positive association, whereas having plural birth and living in rural residence have a significant negative association with MAD intake. These findings highlight that policymakers and other stakeholders had better give prior attention to empowering women, enhance household wealth status and media exposure to increase the MAD intake in the region.

Acculturation and Perceived Ethnic Discrimination Predict Elevated Blood Glucose Level in Sub-Saharan African Immigrants in Australia

Sub-Saharan African migrants experience significant sociocultural challenges, including those related to acculturation and perceived ethnic discrimination (PED), in addition to increased risk of non-communicable diseases, such as type 2 diabetes mellitus (T2DM). Although acculturation and PED are each established risk factors for elevated blood glucose level (EGBL) and T2DM, they have not been studied in relation to EBGL risk in a single model. This study aimed to investigate associations between acculturation, PED and EBGL in a sub-Saharan African migrant population in Australia. Face to face survey using a purposive sampling method was used to collect data from 170 adults, aged 18-72 years. A large proportion (41.8%) of the study group was in the integration mode of acculturation, which strongly correlated positively with EBGL/T2DM, although traditional mode correlated inversely with EBGL/T2DM. PED correlated positively with EBG/LT2DM. Immigrants manifesting the integration mode were 4.2 times more likely to have EBGL/T2DM than other acculturation modes. Multiple linear regression showed that the association between integration mode and EBGL/T2DM was mediated by PED. The apparent interaction between PED and acculturation in relation to EBGL/T2DM risk suggests that interventions to lower T2DM risk in this population may benefit from incorporating strategies to address these two important health determinants.

Depression Mediates Association Between Perceived Ethnic Discrimination and Elevated Blood Glucose Levels Among Sub-Saharan African Migrants in Australia

Depression and perceived ethnic discrimination (PED) are both implicated in type 2 diabetes mellitus (T2DM) risk in some migrant populations. The role of these factors remains understudied in sub-Saharan African migrants, who comprise a significant at-risk group for T2DM in Australia. To assess interactions between PED, depression scores and elevated blood glucose levels among sub-Sahara African immigrants in North-Eastern Australia. Face to face surveys were used to assess PED and depressive tendencies in a purposive sample of 170 adults (aged ≥18 year). Fasting blood glucose levels (FBGL) were measured at the time of interviews. Prevalence of elevated FBGL (≥6.1 mmol/L), PED and severe depression (SD) were: 17.6% (n = 30), 14.7% (n = 25) and 18.8% (n = 32), respectively. Prevalence of elevated FBGL, PED and SD were all higher in males than females. The highest prevalence of elevated BGL, PED and SD each occurred in the 40-50 year age group. Strong positive correlations of both high level PED and SD with elevated FBGL were observed. There was also a strong positive association between PED and SD. Depression score was found to mediate partially the strong association between PED and elevated FBGL (β-value for PED dropped from β = 0.452 to β = 0.246, p < 0.01 and the associated between FBGL and SD remained strong β = 0.554, p < 0.01). The strong association between elevated FBGL and PED seems to be moderated by SD, indicating that interventions to attenuate depression and PED may be a useful adjunct to diabetes prevention programs in this population. Interventions targeted to specific age groups may also be warranted.

Wastewater surveillance for Covid-19: An African perspective

The COVID-19 pandemic has once again highlighted the importance of access to sufficient quantities of safe water and sanitation in public health. In the current COVID-19 pandemic, an early warning wastewater system has been proposed as a platform for SARS-CoV-2 surveillance, and a potentially important public health strategy to combat the disease. This short communication on wastewater surveillance in sub-Saharan Africa highlights challenges, opportunities and alternatives taken into account the local context.

The multidimensional vulnerability of people with disability to HIV infection: Results from the handiSSR study in Bujumbura, Burundi

BACKGROUND

In resource-limited contexts, available data indicate that people with disability are disproportionally affected by the HIV epidemic. While disability resulting from chronic HIV infection has received some attention, few epidemiologic studies have examined the vulnerability of people with disability to HIV acquisition. The aims of the study were as follows: to estimate and compare HIV prevalence among people with and without disability living in Bujumbura, Burundi; to examine how the interaction among disability, gender and socioeconomic environment shapes vulnerability to HIV; and to identify potential pathways to higher HIV risk.

METHODS

In this cross-sectional population-based study, 623 persons with disability (302 with disability onset ≤10 years ["early disability"]) and 609 persons without disability matched for age, sex and location were randomly selected to be tested for HIV and to participate in an interview about their life history, their social environment and their knowledge of sexual health.

FINDINGS

A total of 68% of men and 75% of women with disability were affected by multidimensional poverty compared to 54% and 46% of their peers without disability (p<0.0001). Higher HIV prevalence was observed among women with disability (12.1% [8.2-16]) than among those without (3.8% [1.7-6], ORa 3.8, p<0.0001), while it was similar among men with disability and those without (p = 0·8). Women with disability were also at higher risk of sexual violence than were those without (ORa 2.7, p<0.0001). The vulnerability of women with early disability to HIV was higher among those who were socially isolated (HIV prevalence in this group: 19% [12-27]). In addition, education level and sexual violence mediated 53% of the association between early disability and HIV (p = 0.001).

INTERPRETATION

This study highlights how the intersection of disability, gender and social environment shapes vulnerability to HIV. It also shows that the vulnerability to HIV of women who grew up with a disability is mediated by sexual violence.

A comparative analysis of the diagnostic performances of four clinical probability models for acute pulmonary embolism in a sub-Saharan African population: a cross-sectional study

Background

The diagnosis of acute pulmonary embolism (PE) is one of the most challenging in emergency settings where prompt and accurate decisions need to be taken for life-saving purposes. Here, the assessment of the clinical probability of PE is a paramount step in its diagnosis. Although clinical probability models (CPM) for PE are routinely used in emergency departments (EDs) of low-resource settings, few studies have cited their diagnostic performances in sub-Saharan Africa (SSA). We aimed to comparatively assess the accuracy of four CPM in the diagnosis of acute PE in sub-Saharan Africans.

Methods

We carried out a cross-sectional study to compare the sensitivity, specificity, positive and negative predictive values and accuracy of four CPM namely; the Wells, simplified Wells, revised Geneva and the simplified revised Geneva (SRG) Scores to computed tomography pulmonary angiography (CTPA) in all adults patients with suspected PE admitted to the EDs of the Gynaeco-obstetric and Paediatric Hospital of Yaoundé and the Yaoundé Central Hospital in Cameroon between January 1, 2017 and April 30, 2018.

Results

In total, we enrolled 30 patients with clinical suspicion of acute PE. PE was confirmed on CTPA in 16 (53.3%) cases. Their mean age was 53.7 ± 15.5 years and 36.7% were males. All four scores had a diagnostic performance superior to 50% in all criteria assessed. The simplified Wells score had the highest sensitivity (62.5%) followed by the Wells score (56.3%). The SRG score had the highest specificity (71.4%). The score with highest PPV was the SRG score (66.7%) and that with the highest NPV was the Wells score (56.3%). Overall the models with the highest accuracies were the Wells and SRG scores (60% for each).

Conclusion

All CPM had a suboptimal diagnostic performance, perhaps highlighting the need of a more optimal CPM for acute PE in SSA. However, the Wells and the SRG scores appeared to be most accurate than the other two scores in the ED. Hence, both or either of them may be used in first intention to predict PE and guide which ED patients should undergo further investigations in an emergency SSA setting.

Subjective integration and quality of life of Sub-Saharan African migrants in Germany

OBJECTIVE

This article presents empirical evidence on the quality of life (QoL) of Sub-Saharan African (SSA) migrants in Germany, exploring its association with subjective integration and the influence of some socio-economic and sociodemographic characteristics.

STUDY DESIGN

This is a cross-sectional study design using quantitative data from 518 SSA migrants collected across the 16 federal states of Germany, and these data were analysed in this study.

METHODS

Association between participants' QoL, measured by the four domains of the Bref version of the World Health Organisation QoL measure, subjective integration and sociodemographic characteristics were evaluated using Pearson product-moment correlations. Stepwise multiple linear regressions were performed to explore the contribution of predictor variables on the QoL domain.

RESULTS

Participants' age averaged 32.5 years (standard deviation [SD] 7.93). The sample reported a low QoL score with a mean score of 64.3 (SD 14.4, range 70.2). Multiple linear regression analyses revealed that subjective integration, age, education and gender had significant associations and explained up to 27% of the variance in the QoL domain scores.

CONCLUSION

The findings of this study support the conclusion that subjective integration positively and significantly associates with the physical health, psychological health, social relationships and environmental domains of SSA migrants' QoL in Germany.

Prevalence of severe hypertension in a Sub-Saharan African community

Background

Though some data from in-hospital or selected populations are available, there are no studies reporting community-level prevalence of Severe Hypertension (SH) in sub-Saharan Africa.

Methods

Study participants were recruited within the framework of The Heart Fund's global health initiative. Data were collected in August 2016 from 6 randomly selected sites, ensuring representativeness of both urban and rural areas. Blood pressure (BP) was measured twice, 10 ​min apart, after optimal resting time. SH was defined as systolic blood pressure ≥180 and/or diastolic blood pressure ≥110 ​mmHg ​at both readings. Demographics and data on cardiovascular history/risk factors were collected in the field.

Results

Among 1785 subjects examined, 1182 aged between 18 and 75 years were included in this analysis. The prevalence of SH was 14.1% (12.5% females vs 17.0% males; P ​= ​.03) (Fig. 1). Among participants with severe hypertension, 28.9% were either undiagnosed or untreated. Alarmingly, subjects at high cardiovascular risk (age ​≥ ​60 years and/or obese) had even higher prevalence of overall SH (29.6% and 24.9%, respectively) as well as undiagnosed/untreated SH (29.4% and 24.6%). SH prevalence was almost double in urban compared to rural areas (17.0% vs. 9.2%, P ​= ​.02); however, conversely, undiagnosed/untreated SH was significantly higher in rural areas (50.4% vs 21.9%).

Conclusion

(s): Our community-based study revealed very high prevalence of SH among adults in Abidjan area, with almost one out of every seven having SH. This underscores SH as a growing public health problem in sub-Saharan Africa.

Barriers and motivators of Ghanaian and African-Surinamese migrants to donate blood

African migrants are underrepresented as blood donors in many Western countries, which can lead to shortages of specific blood types for transfusion. More insight in the reasons for this underrepresentation is required to improve blood donor recruitment and retention strategies. The aim of this qualitative study was to explore barriers and motivators for donating blood among migrants of African background. The research population consisted of first and second generation African-Surinamese (n = 20) and Ghanaian (n = 16) migrants living in the Netherlands. In semi-structured personal interviews performed in 2016 and 2017, their experiences and opinions regarding blood donation, barriers, and motivators to (not) become a blood donor and their suggestions to improve recruitment were explored. Data collection was continued until data saturation was achieved. The interviews revealed that although all participants knew about blood donation in general, only four had previously heard of the Dutch national blood bank organisation. Participants expected that if blood was needed, the blood bank would directly approach them, as in their country of origin. Other main blood donation barriers were fear (e.g., of needles, losing too much blood) and issues related to health and non-eligibility to donate. Main motivators were mainly of altruistic nature (e.g., saving a life) and an increased awareness of the need via personal recruitment appeals. It is concluded that expectations regarding donor recruitment-derived from the country of origin-and unawareness of the need for blood can act as important barriers in blood donation among African migrants. Contrary to studies in the United States and Australia, perceived discrimination and social exclusion did not seem to be a donation deterrent among migrants in the Netherlands. Creating awareness of the need of blood by actively approaching, and informing migrants about the donation procedure in the host country, should be considered by blood banks.

Culturally based health assumptions in Sub-Saharan African immigrants: Body mass index predicting self-reported health status

This study examined whether Sub-Saharan African adult immigrants maintained cultural preferences for curvier/higher body size post-migration to the United States. Linear and multiple regression analyses were utilized to discern the predicting effects of Sub-Saharan African immigrants' body mass index score on their self-reported health status at two post-migration data collection points. The initial assessment reveals that Sub-Saharan African immigrants' overweight body mass index score predicted better self-reported health status. Four to six years later, higher body mass index score predicted a better self-reported health status and lower dietary acculturation moderated the predicting effect of body mass index on self-reported health status. Limitations of the study and implications for research and practice are explored.
