Introduction: Adolescence is a critical time for growth and development, but this age group is often neglected in research and development of nutrition interventions. Despite recommendations from the WHO to provide nutrient supplements to adolescents, evidence remains scarce on the most effective supplementation strategy. This study aims to compare weekly iron and folic acid (IFA) supplementation with daily multiple micronutrient supplements (MMSs) in prevention of anaemia and improvement of school outcomes among adolescents in Burkina Faso and Tanzania.

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.

Introduction: Presently, there are few population-level strategies to address SARS-CoV-2 infection except preventive measures such as vaccination. Micronutrient deficiency, particularly vitamin D and zinc deficiency, has been associated with dysregulated host responses, and may play an important role in COVID-19.

Methods And Analysis: We have designed a 2×2 factorial, randomised, double-blind, multi-centre placebo-controlled trial to evaluate the effect of vitamin D and zinc on COVID-19 outcomes in Maharashtra, India.

Article Synopsis
  • The study investigates how changes in body weight and waist circumference together relate to the risk of all-cause mortality, highlighting a gap in existing research on simultaneous changes in these measurements.
  • It analyzes data from two large longitudinal cohort studies conducted in China, involving over 58,000 adults aged 40 and older, assessing their weight and waist size changes over several years.
  • The findings from both cohorts suggest that variations in weight and waist circumference can significantly impact mortality risk, with the analysis employing sophisticated statistical methods to derive associations while controlling for various factors.

Article Synopsis
  • Dietary folate deficiency is a common issue in Sub-Saharan Africa, leading to neural tube defects in infants, particularly among women of reproductive age in Kersa, Eastern Ethiopia.
  • A study measured dietary folate intake using a Food Frequency Questionnaire and found that 33% of participants had low folate intake, with 73.9% at risk for inadequacy, primarily consuming beans, peas, and dark-green vegetables.
  • Factors such as age, economic status, dietary diversity, seasonal employment, and reliance on market foods were linked to low folate intake, highlighting the need for dietary diversification and fortification efforts in Ethiopia.

Background: Nutritionally inadequate diets in Ethiopia contribute to a persisting national burden of adult undernutrition, while the prevalence of noncommunicable diseases (NCDs) is rising.

Objectives: To evaluate performance of a novel Global Diet Quality Score (GDQS) in capturing diet quality outcomes among Ethiopian adults.

Methods: We scored the GDQS and a suite of comparison metrics in secondary analyses of FFQ and 24-hour recall (24HR) data from a population-based cross-sectional survey of nonpregnant, nonlactating women of reproductive age and men (15-49 years) in Addis Ababa and 5 predominately rural regions.

Background: While the causes of anemia at an individual level (such as certain nutritional deficiencies, infections, and genetic disorders) are well defined, there is limited understanding of the relative burden of anemia attributable to each cause within populations.

Objectives: We sought to estimate the proportion of anemia cases attributable to nutrition, infectious diseases, and other risk factors among women, men, and children in 6 regions of Ethiopia.

Methods: A population-based cross-sectional study was conducted.

Objective: To examine the prevalence of and factors associated with different forms of household-level double burden of malnutrition (DBM) in Ethiopia.

Design: We defined DBM using anthropometric measures for adult overweight (BMI ≥ 25 kg/m2), child stunting (height-for-age Z-score <-2 sd) and overweight (weight-for-height Z-score ≥2 sd). We considered sixteen biological, environmental, behavioural and socio-demographic factors.

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.
