The COVID-19 pandemic and its impacts on diet quality and food prices in sub-Saharan Africa.

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.

COVID-19 Preventive Practices, Psychological Distress, and Reported Barriers to Healthcare Access during the Pandemic among Adult Community Members in Sub-Saharan Africa: A Phone Survey.

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.

Continued disruptions in health care services and mental health among health care providers during the COVID-19 pandemic in five sub-Saharan African countries.

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.

Design and Field Methods of the ARISE Network COVID-19 Rapid Monitoring Survey.

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.

Design and field methods of the ARISE Network Adolescent Health Study.

The ARISE Network Adolescent Health Study is an exploratory, community-based survey of 8075 adolescents aged 10-19 in 9 communities in 7 countries: Burkina Faso, Eswatini, Ethiopia, Ghana, Nigeria, Tanzania and Uganda. Communities were selected opportunistically and existing population cohorts maintained by health and demographic surveillance systems (HDSSs). The study is intended to serve as a first round of data collection for African adolescent cohorts, with the overarching goal of generating community-based data on health-related behaviours and associated risk factors in adolescents, to identify disease burdens and health intervention opportunities. Household-based sampling frames were used in each community to randomly select eligible adolescents (aged 10-19 years). Data were collected between July 2015 and December 2017. Consenting participants completed face-to-face interviews with trained research assistants using a standardised questionnaire, which covered physical activity, cigarette and tobacco use, substance and drug use, mental health, sexual behaviours and practices, sexually transmitted infections, pregnancy, food security and food diversity, teeth cleaning and hand washing, feelings and friendship, school and home activities, physical attacks and injuries, health care, health status assessment and life satisfaction, as well as media and cell phone use and socio-demographic and economic background characteristics. Results from this multi-community study serve to identify major adolescent health risks and disease burdens, as well as opportunities for interventions and improvements through policy changes.

L'étude ARISE du réseau sur la santé des adolescents est une étude exploratoire de surveillance basée sur la communauté portant sur 8.075 adolescents âgés de 10 à 19 ans dans 9 communautés de 7 pays: Burkina Faso, Eswatini, Ethiopie, Ghana, Nigéria, Tanzanie et Ouganda. Les communautés ont été sélectionnés de manière opportuniste et les cohortes de population existantes maintenues par des systèmes de surveillance de la santé et démographique (SSSD). L'étude est destinée à servir comme premier cycle de collecte de données pour les cohortes d'adolescents africains, dans le but primordial de générer des données communautaires sur les comportements liés à la santé et les facteurs de risque associés chez les adolescents, afin d'identifier la charge de morbidité et les opportunités d'intervention en matière de santé. Des cadres d'échantillonnage basés sur le ménage ont été utilisés dans chaque communauté pour sélectionner au hasard les adolescents admissibles (âgés de 10-19 ans). Les données ont été collectées entre juillet 2015 et décembre 2017. Les participants consentants ont participé à des entretiens de face à face avec des assistants de recherche formés, à l'aide d'un questionnaire standardisé couvrant l'activité physique, l'usage de la cigarette ou la consommation de tabac, l'usage de drogues et autres substances, la santé mentale, les comportements et pratiques sexuels, les infections sexuellement transmissibles, la grossesse, la sécurité et la diversité alimentaire, le nettoyage des dents et le lavage des mains, les sentiments et les amitiés, les activités scolaires et à domicile, les attaques et les blessures physiques, les soins de santé, l'évaluation de l'état de santé et la satisfaction à l'égard de la vie, l'utilisation des médias et du téléphone portable ainsi que les caractéristiques sociodémographiques et économiques. Les résultats de cette étude portant sur plusieurs communautés permettent d'identifier les principaux risques pour la santé des adolescents et les charges de morbidité, ainsi que les opportunités d'interventions et d'amélioration par le biais de changements de politiques.

The age of opportunity: prevalence of key risk factors among adolescents 10-19 years of age in nine communities in sub-Saharan Africa.

OBJECTIVE: To measure health-related behaviours and risk factors among sub-Saharan African adolescents. METHODS: Cross-sectional study in nine communities in Burkina Faso, Ethiopia, Eswatini, Ghana, Nigeria, Tanzania and Uganda between 2015 and 2017. Community-representative samples of males and females 10-19 years of age were selected. All communities used a uniform questionnaire that was adapted from the WHO Global School-based Student Health Survey. Weighted prevalence estimates and 95% confidence intervals were calculated for each indicator and stratified by age and sex using SAS version 9.4. All prevalence estimates were pooled across communities through random-effects meta-analyses in Stata version 14. RESULTS: A total of 8075 adolescents participated in the study. We observed a high prevalence of inadequate fruit consumption (57-63%) and low physical activity (82-90%); a moderate prevalence of inadequate vegetable consumption (21-31%), unprotected last sex (38-45%), age at first sex <15 years (21-28%) and bullying and physical fighting (12-35%); and a low prevalence of mental health risk factors (1-11%) and alcohol and substance use risk factors (0-6%). We observed a moderate to high prevalence of daily soft drink consumption (21-31%) for all adolescents. Among sexually active adolescents 15-19 years, 37% of females reported ever being pregnant and 8% of males reported to have ever made someone pregnant. Bullying (23%) and physical fighting (35%) were more common among younger male adolescents . The prevalence of low mood was generally higher among older (15-19 years) than younger adolescents (10-14 years). The proportion of adolescents reporting alcohol, drug or cigarette use was very small, with the exception of khat use in Ethiopia. CONCLUSION: Overall, diet and physical activity, violence, sexual and reproductive health, and depression are important risk factors for these sub-Saharan African communities. These findings suggest that more evidence is needed including novel efforts for the collection of sensitive information, as well as a need to move towards community-tailored interventions to reach adolescent populations with varying needs.

OBJECTIF: Mesurer les comportements liés à la santé et les facteurs de risque chez les adolescents africains subsahariens. MÉTHODES: Etude transversale dans neuf communautés au Burkina Faso, en Ethiopie, à Eswatini, au Ghana, au Nigéria, en Tanzanie et en Ouganda entre 2015 et 2017. Des échantillons représentatifs de la communauté composés d'hommes et de femmes âgés de 10 à 19 ans ont été sélectionnés. Toutes les communautés ont utilisé un questionnaire uniforme adapté de l'Enquête Mondiale sur la Santé des Elèves de l'OMS. Les estimations de prévalence pondérée et les intervalles de confiance à 95% ont été calculés pour chaque indicateur et stratifiées par âge et sexe à l'aide de la version 9.4 de SAS. Toutes les estimations de prévalence ont été poolées dans les communautés via des méta-analyses à effets aléatoires dans Stata, version 14. RÉSULTATS: 8.075 adolescents ont participé à l'étude. Nous avons observé une prévalence élevée de consommation insuffisante de fruits (57-63%) et de faible activité physique (82-90%); une prévalence modérée de consommation insuffisante de légumes (21-31%), du dernier rapport sexuel non protégé (38-45%), du premier rapport sexuel à moins de 15 ans (21-28%) et de l'intimidation et des combats physiques (12-35%), une faible prévalence de facteurs de risque pour la santé mentale (1-11%) et de facteurs de risque pour la consommation d'alcool et de substances (0-6%). Nous avons observé une prévalence modérée à élevée de consommation quotidienne de boissons gazeuses (21-31%) chez tous les adolescents. Parmi les adolescents sexuellement actifs âgées de 15 à 19 ans, 37,0% des femmes ont déclaré avoir déjà été enceintes et 8,0% des hommes ont rapporté avoir déjà enceinté une femme. L'intimidation (23%) et les combats physiques étaient plus fréquents chez les adolescents plus jeunes (35%). La prévalence de la mauvaise humeur était généralement plus élevée chez les adolescents d'âge plus élevé (de 15 à 19 ans) que chez les plus jeunes (de 10 à 14 ans). La proportion d'adolescents déclarant avoir consommé de l'alcool, des drogues ou des cigarettes était très faible, à l'exception de la consommation de khat en Ethiopie. CONCLUSION: Dans l'ensemble, le régime alimentaire et l'activité physique, la violence, la santé sexuelle et reproductive et la dépression sont des facteurs de risque importants pour ces communautés d'Afrique subsaharienne. Ces résultats suggèrent que davantage de données sont nécessaires, notamment de nouveaux efforts pour la collecte d'informations sensibles, ainsi que la nécessité de passer à des interventions adaptées aux communautés pour atteindre les populations adolescentes avec des besoins variés.

Performance of Low-Cost Agar from Gracilaria salicornia on Tissue Culture of Pleurotus HK-37.

Currently, the demand of Pleurotus HK-37 (oyster mushroom) in Tanzania is growing rapidly due to the increasing of awareness on its nutrition, health, and economic benefits. Despite the increasing demand, the availability of strains of Pleurotus HK-37 species is still a challenge due to high cost of tissue culture technology. The high cost of importing agar seems to be among the factors for this failure. This study aimed at investigating the performance of low-cost agar from local Gracilaria salicornia on tissue culture of Pleurotus HK-37. Local extracted agars with different gel strengths ranging between 100, 200, 300, 400, and 500 g/cm2 were used to make PDA media. The average mycelia growth rate (mm/day) ranged between 9.87 ± 1.44 and 14.9 ± 0.85 mm/day. Low-cost agar shows quite similar performance as that of standard agar on active growth of Pleurotus HK-37 mycelia. All PDA plates appeared white and feathery and showed to grow in a circular mode (radial extension). Mycelia growth on standard agar PDA took 5 days while on extracted local agar PDA took 5 to 7 days to fully colonize the plate at 27 ± 2°C. The present study shows that the production cost can be reduced by ∼35-78% by using local agar.

Socio-economic and spatial correlates of subclinical iodine deficiency among pregnant women age 15-49 years in Tanzania.

BACKGROUND: Iodine deficiency is a widespread global health problem that affects about 2 billion people each year. Pregnant women are particularly vulnerable to iodine deficiency due to increased iodine requirement leading to death, miscarriage, and stillbirth. Iodine deficiency also has significant negative effects on newborns including impaired cognitive development, impaired learning capabilities, and stunting. This study looks at the association between subclinical iodine deficiency and demographic factors including age, wealth index, education, family size, geographical zone, number of children, fish consumption, pregnancy trimester and household salt in pregnant women aged 15-49 years in Tanzania. METHODS: The 2010 Tanzania Demographic and Health Survey (TDHS) data was re analysed. Subclinical iodine deficiency is classified as a urinary iodine concentration (UIC) of <150 µg/L. RESULTS: Results showed that the prevalence of iodine deficiency (54%) was unacceptably high among pregnant women. The results of multiple logistic regression model found that number of children, wealth index, household salt, and geographical zone were significantly associated with iodine deficiency in these women. CONCLUSION: These results indicate a need to implement interventions to increase iodine intake that targets pregnant women with the specific demographic characteristics.
