RESUMO

OBJECTIVES: Long-acting reversible contraception (LARC) initiation has been well-studied and intervened upon. Because LARC requires provider intervention for initiation and removal, it is critical to measure informed choice at the time of desired discontinuation as well. We examined perceptions of access to LARC discontinuation among women at two sites in Burkina Faso, where LARC is the dominant method in the contraceptive mix. STUDY DESIGN: We analyzed data from a 2017-2018 population-based, cross-sectional survey of 281 implant users and 55 intrauterine device users at two sites in Burkina Faso. We measured perceptions of access to LARC discontinuation through survey items assessing whether participants (1) were informed on how to discontinue the method, (2) believed they could have LARC removed without a lot of difficulty, (3) believed cost would be a barrier to discontinuation, (4) had ever attempted to have a provider remove LARC, and (5) successfully had LARC removed. The distribution of these measures was examined in the population and for differences by gravida, parity, domestic partnership, fertility desires, and recency of last childbirth. RESULTS: Thirty-eight (11%) of current LARC users reported that they were not informed on how to discontinue, 56 (17%) believed having their device removed would be difficult, and 54 (16%) believed cost would be a barrier to removal. Of women who attempted removal, providers did not immediately remove LARC on request for 10 (28%). CONCLUSIONS: Findings indicate that LARC uptake is an insufficient measure of reproductive access or choice. Future studies should include patient-centered measures that span the full duration of contraceptive use. IMPLICATIONS: This paper finds that a sizable proportion of LARC users lack information about method discontinuation and perceive or experience barriers to method removal. These findings call for a reconsideration of free and informed contraceptive choice to include the entire duration of contraceptive use, not only the time of method provision.

RESUMO

There is very limited data on the extent and determinants of COVID-19 vaccine hesitancy among adults living in sub-Saharan Africa since the global roll-out of vaccines began in 2021. This multi-country survey sought to investigate COVID-19 vaccine hesitancy and other predictors of readiness to get vaccinated. We conducted surveys among adults residing in nine urban and rural areas in Burkina Faso, Ethiopia, Ghana, Nigeria, and Tanzania in late 2021. Log binomial regression models were used to identify prevalence and factors associated with vaccine hesitancy and beliefs around COVID-19 misinformation. We completed a total of 2,833 interviews. Among all respondents, 9% had never heard of a COVID-19 vaccine, 12% had been vaccinated, and 20% knew someone else who had been vaccinated. The prevalence of vaccine hesitancy varied by country (Ethiopia 29%, Burkina Faso 33%, Nigeria 34%, Ghana 42%, Tanzania 65%), but not by rural or urban context. People who did not think the vaccine was safe or effective, or who were unsure about it, were more likely to be vaccine hesitant. Those who reported they did not have a trusted source of information about the vaccine (aPR: 1.25, 95% CI: 1.18,1.31) and those who thought the vaccine would not be made available to them within the year were more likely to be vaccine hesitant. Women were more likely to be vaccine hesitant (aPR: 1.31, 95% CI: 1.19,1.43) and believe COVID-19 falsehoods (aPR: 1.05, 95% CI: 1.02,1.08). The most commonly believed falsehoods were that the vaccine was developed too fast and that there was not enough information about whether the vaccine was effective or not. Educational campaigns targeted at misinformation and tailored to suit each country are recommended to build trust in COVID-19 vaccines and reduce hesitancy.

RESUMO

BACKGROUND: Sub-Saharan Africa faces prolonged COVID-19 related impacts on economic activity, livelihoods and nutrition, with recovery slowed down by lagging vaccination progress. OBJECTIVE: This study investigated the economic impacts of COVID-19 on food prices, consumption and dietary quality in Burkina Faso, Ethiopia, Ghana, Nigeria, and Tanzania. METHODS: We conducted a repeated cross-sectional study using a mobile platform to collect data from July-December, 2021 (round 2). We assessed participants' dietary intake of 20 food groups over the previous seven days and computed the primary outcome, the Prime Diet Quality Score (PDQS), and Dietary Diversity Score (DDS), with higher scores indicating better quality diets. We used generalized estimating equation (GEE) linear regression models to assess factors associated with diet quality during COVID-19. RESULTS: Most of the respondents were male and the mean age was 42.4 (±12.5) years. Mean PDQS (±SD) was low at 19.4(±3.8), out of a maximum score of 40 in this study. Respondents (80%) reported higher than expected prices for all food groups. Secondary education or higher (estimate: 0.73, 95% CI: 0.32, 1.15), medium wealth status (estimate: 0.48, 95% CI: 0.14, 0.81), and older age were associated with higher PDQS. Farmers and casual laborers (estimate: -0.60, 95% CI: -1.11, -0.09), lower crop production (estimate: -0.87, 95% CI: -1.28, -0.46) and not engaged in farming (estimate: -1.38, 95% CI: -1.74, -1.02) were associated with lower PDQS. CONCLUSION: Higher food prices and lower diet quality persisted during the COVID-19 pandemic. Economic and social vulnerability and reliance on markets (and lower agriculture production) were negatively associated with diet quality. Although recovery was evident, consumption of healthy diets remained low. Systematic efforts to address the underlying causes of poor diet quality through transforming food system value chains, and mitigation measures, including social protection programs and national policies are critical.

RESUMO

INTRODUCTION: Provider bias has become an important topic of family planning research over the past several decades. Much existing research on provider bias has focused on the ways providers restrict access to contraception. Here, we propose a distinction between the classical "downward" provider bias that discourages contraceptive use and a new conception of "upward" provider bias that occurs when providers pressure or encourage clients to adopt contraception. METHODS: Using cross-sectional data from reproductive-aged women in Burkina Faso, we describe lifetime prevalence of experiencing provider encouragement to use contraception due to provider perceptions of high parity (a type of upward provider bias) and provider discouragement from using contraception due to provider perceptions of low parity (a type of downward provider bias). We also examine associations between sociodemographic characteristics and experiences of provider encouragement to use contraception due to perceptions of high parity. RESULTS: Sixteen percent of participants reported that a provider had encouraged them to use contraception due to provider perceptions of high parity, and 1% of participants reported that a provider had discouraged them from using contraception because of provider perceptions of low parity. Being married, being from the rural site, having higher parity, and having attended the 45th-day postpartum check-up were associated with increased odds of being encouraged to use contraception due to provider perceptions of high parity. CONCLUSION: We find that experiences of upward provider bias linked to provider perceptions of high parity were considerably more common in this setting than downward provider bias linked to perceptions of low parity. Research into the mechanisms through which upward provider bias operates and how it may be mitigated is imperative to promote contraceptive autonomy.

RESUMO

Family planning researchers have traditionally focused efforts on understanding contraceptive non-use and promoting contraceptive uptake. Recently, however, more scholars have been exploring method dissatisfaction, questioning the assumption that contraceptive users necessarily have their needs met. Here, we introduce the concept of "non-preferred method use", which we define as the use of one contraceptive method while having the desire to use a different method. Non-preferred method use reflects barriers to contraceptive autonomy and may contribute to method discontinuation. We use survey data collected from 2017 to 2018 to better understand non-preferred contraceptive method use among 1210 reproductive-aged family planning users in Burkina Faso. We operationalise non-preferred method use as both (1) use of a method that was not the user's original preference and (2) use of a method while reporting preference for another method. Using these two approaches, we describe the prevalence of non-preferred method use, reasons for using non-preferred methods, and patterns in non-preferred method use by current and preferred methods. We find that 7% of respondents reported using a method they did not desire at the time of adoption, 33% would use a different method if they could and 37% report at least one form of non-preferred method use. Many women cite facility-level barriers, such as providers refusing to give them their preferred method, as reasons for non-preferred method use. The high prevalence of non-preferred method use reflects the obstacles that women face when attempting to fulfil their contraceptive desires. Further research on reasons for use of non-preferred methods is necessary to promote contraceptive autonomy.

RESUMO

INTRODUCTION: The global obesity epidemic and its adverse health effects have reached sub-Saharan Africa. In some urban settings, like Burkina Faso's capital Ouagadougou, up to 43% of the adult population are overweight or obese. At the same time, modernised food systems are responsible for 26% of global greenhouse gas emissions, 50% of land use and 70% of freshwater use. International guidelines on the treatment of overweight and obesity recommend dietary intervention programmes that promote reduced calorie intake and increased physical activity. So far, weight loss interventions rarely consider sustainable dietary concepts, including healthfulness, affordability, cultural appropriateness and environmental friendliness. Therefore, we present a study protocol of a novel randomised controlled trial that aims to establish the effects of a sustainable weight loss intervention on cardiometabolic and environmental outcomes in urban Burkina Faso. METHODS AND ANALYSIS: We conduct a non-blinded randomised controlled trial, comparing a 6-month sustainable diet weight loss intervention programme (n=125) with a standard weight loss information material and 5 min oral counselling at baseline (n=125). Primary outcome is a reduction in fasting plasma glucose of ≥0.1 mmol/L. Outcome measures are assessed at baseline, after 6 months and after 12 months. ETHICS AND DISSEMINATION: Ethical approval for the study has been obtained from the Medical Faculty of Heidelberg University (S-376/2019) and from the Ministry of Health and the Ministry of Higher Education, Scientific Research and Innovation in Ouagadougou, Burkina Faso (No 2021-01-001). The results of the study will be disseminated to local stakeholders at a final project meeting and to the wider research community through peer-reviewed publications and conferences. TRIAL REGISTRATION NUMBER: DRKS00025991.

RESUMO

Unmet need for contraception is a widely used but frequently misunderstood indicator. Although calculated from measures of pregnancy intention and current contraceptive use, unmet need is commonly used as a proxy measure for (1) lack of access to contraception and (2) desire to use it. Using data from a survey in Burkina Faso, we examine the extent to which unmet need corresponds with and diverges from these two concepts, calculating sensitivity, specificity, and positive/negative predictive values. Among women assigned conventional unmet need, 67 percent report no desire to use contraception and 61 percent report access to a broad range of affordable contraceptives. Results show unmet need has low sensitivity and specificity in differentiating those who lack access and/or who desire to use a method from those who do not. These findings suggest that unmet need is of limited utility to inform family planning programs and may be leading stakeholders to overestimate the proportion of women in need of expanded family planning services. We conclude that more direct measures are feasible at the population level, rendering the proxy measure of unmet need unnecessary. Where access to and/or desire for contraception are the true outcomes of interest, more direct measures should be used.

RESUMO

There is growing consensus in the family planning community around the need for novel measures of autonomy. Existing literature highlights the tension between efforts to pursue contraceptive targets and maximize uptake on the one hand, and efforts to promote quality, person-centeredness, and contraceptive autonomy on the other hand. Here, we pilot a novel measure of contraceptive autonomy, measuring it at two Health and Demographic Surveillance System sites in Burkina Faso. We conducted a population-based survey with 3,929 women of reproductive age, testing an array of new survey items within the three subdomains of informed choice, full choice, and free choice. In addition to providing tentative estimates of the prevalence of contraceptive autonomy and its subdomains in our sample of Burkinabè women, we critically examine which parts of the proposed methodology worked well, what challenges/limitations we encountered, and what next steps might be for refining, improving, and validating the indicator. We demonstrate that contraceptive autonomy can be measured at the population level but a number of complex measurement challenges remain. Rather than a final validated tool, we consider this a step on a long road toward a more person-centered measurement agenda for the global family planning community.

RESUMO

PURPOSE: This multicountry survey assessed the levels and the determinants of the impacts of the pandemic on education and mental health among adolescents in sub-Saharan Africa and the potential factors that may exacerbate these adverse impacts. METHODS: A phone survey was conducted among adolescents in nine diverse areas in Burkina Faso, Ethiopia, Ghana, Nigeria, and Tanzania between July and December 2021. Approximately 300 adolescents per area and 2,803 adolescents in total were included. The survey collected information on adolescents' sociodemographic characteristics, current COVID-19 preventive measures, and the impacts of the pandemic on daily activities, education, and mental health. Log-binomial models were used to calculate the adjusted prevalence ratios (aPRs) for determinants of education and mental health outcomes. RESULTS: Overall, 17% of the adolescents were not receiving any education. Compared to boys, girls were 15% more likely than boys to lack fully in-person education (aPR: 1.15; 95% confidence interval [CI]: 1.02, 1.30). Rural residence was associated with 2.7 times the prevalence of not currently receiving any education (aPR: 2.68; 95% CI: 2.23, 3.22). Self-reported experience of the current impacts of the pandemic on daily activities was associated with a higher prevalence of possible psychological distress (aPR: 1.86; 95% CI: 1.55, 2.24), high anxiety level (aPR: 3.37; 95% CI: 2.25, 5.06), and high depression level (aPR: 3.01; 95% CI: 2.05, 4.41). DISCUSSION: The COVID-19 pandemic presents continued challenges to adolescents' education and mental health. Multisectoral efforts are needed to ensure that adolescents in sub-Saharan Africa do not fall further behind due to the pandemic.

RESUMO

The COVID-19 pandemic has had serious negative health and economic impacts in sub-Saharan Africa. Continuous monitoring of these impacts is crucial to formulate interventions to minimize the consequences of COVID-19. This study surveyed 2,829 adults in urban and rural sites among five sub-Saharan African countries: Burkina Faso, Ethiopia, Nigeria, Tanzania, and Ghana. Participants completed a mobile phone survey that assessed self-reported sociodemographics, COVID-19 preventive practices, psychological distress, and barriers to healthcare access. A modified Poisson regression model was used to estimate adjusted prevalence ratios (aPRs) and 95% CIs to investigate potential factors related to psychological distress and barriers to reduced healthcare access. At least 15.6% of adults reported experiencing any psychological distress in the previous 2 weeks, and 10.5% reported that at least one essential healthcare service was difficult to access 2 years into the pandemic. The majority of participants reported using several COVID-19 preventive methods, with varying proportions across the sites. Participants in the urban site of Ouagadougou, Burkina Faso (aPR: 2.29; 95% CI: 1.74-3.03) and in the rural site of Kintampo, Ghana (aPR: 1.68; 95% CI: 1.21-2.34) had a higher likelihood of experiencing any psychological distress compared with those in the rural area of Nouna, Burkina Faso. Loss of employment due to COVID-19 (aPR: 1.77; 95% CI: 1.47-2.11) was also associated with an increased prevalence of psychological distress. The number of children under 5 years in the household (aPR: 1.23; 95% CI: 1.14-1.33) and participant self-reported psychological distress (aPR: 1.83; 95% CI: 1.48-2.27) were associated with an increased prevalence of reporting barriers to accessing health services, whereas wage employment (aPR: 0.67; 95% CI: 0.49-0.90) was associated with decreased prevalence of reporting barriers to accessing health services. Overall, we found a high prevalence of psychological distress and interruptions in access to healthcare services 2 years into the pandemic across five sub-Saharan African countries. Increased effort and attention should be given to addressing the negative impacts of COVID-19 on psychological distress. An equitable and collaborative approach to new and existing preventive measures for COVID-19 is crucial to limit the consequences of COVID-19 on the health of adults in sub-Saharan Africa.

RESUMO

Background: Continuous monitoring of the pandemic's impact on health service provision and mental health, COVID-19 perceptions, and compliance with prevention measures among health care providers (HCPs) can help with mitigating the pandemic's negative effects. Methods: A computer-assisted telephone interviewing (CATI) survey was conducted among 1499 HCPs in Burkina Faso (Ouagadougou), Ethiopia (Addis Ababa), Nigeria (Lagos and Ibadan), Tanzania (Dar es Salaam), and Ghana (Kintampo). Self-reported mental health, perceptions of the COVID-19 pandemic, and prevention measures available in the workplace were assessed. HCPs' responses to questions regarding the impact of COVID-19 on nine essential health services were summed into a score; high service disruption was defined as a score higher than the total average score across all sites. Modified Poisson regression was used to identify potential factors related to high service disruption. Results: Overall, 26.9% of HCPs reported high service disruption, with considerable differences across sites (from 1.6% in Dar es Salaam to 45.0% in Addis Ababa). A considerable proportion of HCPs reported experiencing mild psychological distress (9.4%), anxiety (8.0%), and social avoidance or rejection (13.9%) due to their profession. Participants in Addis Ababa (absolute risk ratio (ARR) = 2.10; 95% confidence interval (CI) = 1.59-2.74), Lagos (ARR = 1.65; 95% CI = 1.24-2.17), and Kintampo (ARR = 2.61; 95% CI = 1.94-3.52) had a higher likelihood of reporting high service disruption compared to those in Ouagadougou. Reporting ever-testing for COVID-19 (ARR = 0.82; 95% CI = 0.69-0.97) and the presence of COVID-19 guidelines in the workplace (ARR = 0.63; 95% CI = 0.53-0.77) were both associated with lower reported health service disruption among HCPs. Conclusion: The COVID-19 pandemic continues to disrupt essential health services and present a challenge to HCPs' mental health, with important differences across countries and settings; interventions are needed to mitigate these negative effects of the pandemic.

RESUMO

Population-based intervention coverage data are used to inform the design of projects, programs, and policies and to evaluate their impact. In low- and middle-income countries (LMICs), household surveys are the primary source of coverage data. Many coverage surveys are implemented by organizations with limited experience or resources in population-based data collection. We developed a streamlined survey and set of supporting materials to facilitate rigorous survey design and implementation. The RADAR coverage survey tool aimed to 1) rigorously measure priority reproductive, maternal, newborn, child health & nutrition coverage indicators, and allow for equity and gender analyses; 2) use standard, valid questions, to the extent possible; 3) be as light as possible; 4) be flexible to address users' needs; and 5) be compatible with the Lives Saved Tool for analysis of program impact. Early interactions with stakeholders also highlighted survey planning, implementation, and analysis as challenging areas. We therefore developed a suite of resources to support implementers in these areas. The toolkit was piloted by implementers in Tanzania and in Burkina Faso. Although the toolkit was successfully implemented in these settings and facilitated survey planning and implementation, we found that implementers must still have access to sufficient resources, time, and technical expertise in order to use the tool appropriately. This potentially limits the use of the tool to situations where high-quality surveys or evaluations have been prioritized and adequately resourced.

RESUMO

While typhoid fever has largely been eliminated in high-income regions which have developed modern water, sanitation, and hygiene facilities, it remains a significant public health burden resulting in morbidity and mortality among millions of individuals in resource-constrained settings. Prevention and control efforts are needed that integrate several high-impact interventions targeting facilities and infrastructure, including those addressing improvements in sanitation, access to safe water, and planned urbanization, together with parallel efforts directed at effective strategies for use of typhoid conjugate vaccines (TCV). The use of TCVs is a critical tool with the potential of having a rapid impact on typhoid fever disease burden; their introduction will also serve as an important strategy to combat evolving antimicrobial resistance to currently available typhoid fever treatments. Well-designed epidemiological surveillance studies play a critical role in establishing the need for, and monitoring the impact of, typhoid fever control and prevention strategies implemented by public health authorities. Here, we present a perspective based on a narrative review of the impact of typhoid fever on morbidity and mortality in sub-Saharan Africa and discuss ongoing surveillance activities and the role of vaccination in prevention and control efforts.

RESUMO

COVID-19 vaccine hesitancy among adolescents poses a challenge to the global effort to control the pandemic. This multi-country survey aimed to assess the prevalence and determinants of COVID-19 vaccine hesitancy among adolescents in sub-Saharan Africa between July and December 2021. The survey was conducted using computer-assisted telephone interviewing among adolescents in five sub-Saharan African countries, Burkina Faso, Ethiopia, Ghana, Nigeria, and Tanzania. A rural area and an urban area were included in each country (except Ghana, which only had a rural area), with approximately 300 adolescents in each area and 2662 in total. Sociodemographic characteristics and perceptions and attitudes on COVID-19 vaccines were measured. Vaccine hesitancy was defined as definitely not getting vaccinated or being undecided on whether to get vaccinated if a COVID-19 vaccine were available. Log-binomial models were used to calculate the adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) for associations between potential determinants and COVID-19 vaccine hesitancy. The percentage of COVID-19 vaccine hesitancy was 14% in rural Kersa, 23% in rural Ibadan, 31% in rural Nouna, 32% in urban Ouagadougou, 37% in urban Addis Ababa, 48% in rural Kintampo, 65% in urban Lagos, 76% in urban Dar es Salaam, and 88% in rural Dodoma. Perceived low necessity, concerns about vaccine safety, and concerns about vaccine effectiveness were the leading reasons for hesitancy. Healthcare workers, parents or family members, and schoolteachers had the greatest impacts on vaccine willingness. Perceived lack of safety (aPR: 3.52; 95% CI: 3.00, 4.13) and lack of effectiveness (aPR: 3.46; 95% CI: 2.97, 4.03) were associated with greater vaccine hesitancy. The prevalence of COVID-19 vaccine hesitancy among adolescents is alarmingly high across the five sub-Saharan African countries, especially in Tanzania. COVID-19 vaccination campaigns among sub-Saharan African adolescents should address their concerns and misconceptions about vaccine safety and effectiveness.

RESUMO

BACKGROUND: Invasive non-typhoidal Salmonella (iNTS) is one of the leading causes of bacteraemia in sub-Saharan Africa. We aimed to provide a better understanding of the genetic characteristics and transmission patterns associated with multi-drug resistant (MDR) iNTS serovars across the continent. METHODS: A total of 166 iNTS isolates collected from a multi-centre surveillance in 10 African countries (2010-2014) and a fever study in Ghana (2007-2009) were genome sequenced to investigate the geographical distribution, antimicrobial genetic determinants and population structure of iNTS serotypes-genotypes. Phylogenetic analyses were conducted in the context of the existing genomic frameworks for various iNTS serovars. Population-based incidence of MDR-iNTS disease was estimated in each study site. RESULTS: Salmonella Typhimurium sequence-type (ST) 313 and Salmonella Enteritidis ST11 were predominant, and both exhibited high frequencies of MDR; Salmonella Dublin ST10 was identified in West Africa only. Mutations in the gyrA gene (fluoroquinolone resistance) were identified in S. Enteritidis and S. Typhimurium in Ghana; an ST313 isolate carrying blaCTX-M-15 was found in Kenya. International transmission of MDR ST313 (lineage II) and MDR ST11 (West African clade) was observed between Ghana and neighbouring West African countries. The incidence of MDR-iNTS disease exceeded 100/100 000 person-years-of-observation in children aged <5 years in several West African countries. CONCLUSIONS: We identified the circulation of multiple MDR iNTS serovar STs in the sampled sub-Saharan African countries. Investment in the development and deployment of iNTS vaccines coupled with intensified antimicrobial resistance surveillance are essential to limit the impact of these pathogens in Africa.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented public health crisis globally. Understanding healthcare providers' (HCPs') knowledge and perceptions of COVID-19 is crucial to identifying effective strategies to improve their ability to respond to the pandemic in sub-Saharan Africa. A phone-based survey of 900 HCPs in Burkina Faso, Ethiopia, and Nigeria (300 per country) was conducted to assess knowledge, perceptions, COVID-19 prevention measures, stigma, and mental health of HCPs. Modified Poisson regression models were used to evaluate predictors of knowledge, perceptions, and prevention measures; adjusted risk ratios (ARRs) and 95% confidence intervals (CIs) were calculated. Three-fourths of the HCPs had adequate knowledge, and over half had correct perceptions of risk and high levels of self-reported prevention measures. The majority of the HCPs (73.7%) reported self-perceived social stigma. There was relatively low prevalence of depression (6.6%), anxiety (6.6%), or psychological distress (18%). Compared with doctors, being a nurse was associated with lower levels of knowledge (ARR: 0.83; 95% CI: 0.77-0.90) and was also negatively associated with having correct perceptions toward COVID-19 (AOR: 0.82; 95% CI: 0.73-0.92). HCPs treating COVID-19 patients had higher likelihood of having high levels of prevention measures (AOR: 1.37; 95% CI: 1.23-1.53). Despite high levels of knowledge among HCPs in sub-Saharan Africa, there is a need to improve COVID-19 perceptions and compliance with prevention measures as well as address social stigma toward HCPs to better ensure their safety and prepare them to deliver health services.

RESUMO

The public health measures instituted by governments to combat the coronavirus disease 2019 (COVID-19) may cause developmental and educational losses to adolescents. The impacts of the COVID-19 pandemic and its mitigation strategies on adolescents in sub-Saharan Africa are unclear. This study aimed to examine adolescents' knowledge, perceptions, and practices related to COVID-19 and the impacts of the pandemic on the daily lives of adolescents in sub-Saharan Africa. The survey was conducted in Burkina Faso, Ethiopia, and Nigeria using computer-assisted telephone interviews to enable rapid and remote data collection. Two sites were included in each country, with approximately 300 adolescents per site and 1,795 adolescents in total. Variations across the six sites were noted for the proportions of the adolescents who could correctly identify all key COVID-19 symptoms (4-25%), transmission methods (16-59%), and prevention approaches (33-79%). Most (> 72%) of the adolescents were no longer going to school due to school closures. Many adolescents (23-81%) were not receiving any education during the pandemic. A considerable proportion of the adolescents (44-83%) self-assessed as having less ability to learn during the pandemic; many expected it to be very difficult to catch up on education after the pandemic. Decreases in the consumption of major food groups were common across sites. Urgent actions are needed in sub-Saharan Africa to address the inadequate knowledge of COVID-19 among adolescents and the impacts of the pandemic on adolescent education and nutrition.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has significant health and economic ramifications across sub-Saharan Africa (SSA). Data regarding its far-reaching impacts are severely lacking, thereby hindering the development of evidence-based strategies to mitigate its direct and indirect health consequences. To address this need, the Africa Research, Implementation Science, and Education (ARISE) Network established a mobile survey platform in SSA to generate longitudinal data regarding knowledge, attitudes, and practices (KAP) related to COVID-19 prevention and management and to evaluate the impact of COVID-19 on health and socioeconomic domains. We conducted a baseline survey of 900 healthcare workers, 1,795 adolescents 10 to 19 years of age, and 1,797 adults 20 years or older at six urban and rural sites in Burkina Faso, Ethiopia, and Nigeria. Households were selected using sampling frames of existing Health and Demographic Surveillance Systems or national surveys when possible. Healthcare providers in urban areas were sampled using lists from professional associations. Data were collected through computer-assisted telephone interviews from July to November 2020. Consenting participants responded to surveys assessing KAP and the impact of the pandemic on nutrition, food security, healthcare access and utilization, lifestyle, and mental health. We found that mobile telephone surveys can be a rapid and reliable strategy for data collection during emergencies, but challenges exist with response rates. Maintaining accurate databases of telephone numbers and conducting brief baseline in-person visits can improve response rates. The challenges and lessons learned from this effort can inform future survey efforts during COVID-19 and other emergencies, as well as remote data collection in SSA in general.

RESUMO

Coronavirus disease 2019 (COVID-19) can have far-reaching consequences for developing countries through the combined effects of infection and mortality, and the mitigation measures that can impact food systems and diets. Using a mobile platform, this cross-sectional study evaluated the effect of COVID-19 on food prices and dietary quality for 1797 households in Nouna and Ouagadougou in Burkina Faso, Addis Ababa and Kersa in Ethiopia, and Lagos and Ibadan in Nigeria. We assessed the consumption of 20 food groups during the previous 7 days. The dietary diversity scores (DDS) and Prime Diet Quality Scores (PDQS) were used to assess dietary diversity and quality. We used generalized estimating equation (GEE) linear models to evaluate associations between price changes for staples, pulses, vegetables, fruits, and animal source foods (ASFs) with the DDS and PDQS PDQS. Most participants reported increasing prices of staples, pulses, fruits, vegetables and ASF, and ≥ 40% reported the decreased consumption of staples, legumes, and other vegetables and fruits. The DDS (except in Kersa and Ouagadougou) and PDQS were lower during the COVID-19 pandemic. Higher pulse prices were associated with lower DDS (estimate, -0.35; 95% confidence interval [CI], -0.74 to 0.03; P = 0.07) in the combined analysis and in Burkina Faso (estimate, -0.47; 95% CI, -0.82 to -0.11). Higher vegetable prices were positively associated with the DDS (estimate, 0.22; 95% CI, 0.08 to 0.37). Lower crop production (estimate, -0.54; 95% CI, -0.80 to -0.27) was associated with lower DDS. The price increases and worsening dietary diversity and quality call for social protection and other strategies to increase the availability and affordability of nutrient-rich foods during the COVID-19 pandemic and public health emergencies.

RESUMO

Coronavirus disease 2019 (COVID-19) is a public health emergency affecting the lives of millions of people globally. Different measures and extraordinary steps are being taken to contain the transmission of the virus. The levels of knowledge and implementation of preventive practices related to COVID-19 in sub-Saharan African countries are unclear. Additionally, there is a lack of evidence regarding the impacts of the pandemic on mental health. This study aimed to describe knowledge and practices related to COVID-19 and to assess mental health status among adults in three sub-Saharan African countries: Burkina Faso, Ethiopia, and Nigeria. A total of 1,797 adults were included in the survey, and data were collected using computer-assisted telephone interviews. The proportions of adults who identified more than 80% of COVID-19 symptoms, transmission methods, and prevention mechanisms were 69.9%, 79.2%, and 90.7%, respectively. The practice of preventive measures was relatively lower for avoiding social gatherings and disinfecting contaminated surfaces. Better education, urban residence, and believing the pandemic is real were factors associated with good knowledge on COVID-19 symptoms, transmission methods, and preventive actions. Additionally, being male was associated with good knowledge on symptoms and transmission methods, whereas being in an older age group was associated with knowledge of transmission methods. Mild, moderate, and severe psychological distress was reported by 20.6%, 5.9%, and 1.1% of the participants, respectively. Although this study found high levels of knowledge regarding COVID-19, interventions are needed to increase the uptake of recommended preventive practices among adults in sub-Saharan Africa.
