In sub-Saharan Africa, the reasons for low rates of COVID-19 vaccination and unwillingness to accept vaccine vary, so country-specific solutions are needed.1Lazarus JV Ratzan SC Palayew A et al.A global survey potential acceptance a vaccine.Nat Med. 2021; 27: 225-228Crossref PubMed Scopus (1075) Google Scholar Public health action that is humane, culturally relevant, recognises contribution historical, structural, other system dynamics has been called for.2Mutombo PN Fallah MP Munodawafa D...
The South African response to the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus was swift and assertive, although it came with economic social costs.

Anaemia continues to be a persistent concern among South African women of reproductive age (WRA), yet population specific information on its determinants remains sparse. We used baseline data from the Healthy Lives Trajectory Initiative randomised trial (n = 480) quantify factors associated with anaemia in Soweto, Africa aged 18–25 years. multivariable logistic regression describe associations and structural equation modelling assess theoretical model, which tested three categories...
In South Africa, public perceptions of the COVID-19 pandemic and risk mitigation measures remain mixed. To better understand health behaviours in context COVID-19, a qualitative study was conducted, which aimed to investigate relating among African adult population.
In South Africa, haemoglobin (Hb) is measured to screen for iron deficiency (ID). However, low levels of Hb are only a late stage indicator ID. Furthermore, values generally not adjusted altitude even though recommended by WHO. We determined the threshold with highest combined sensitivity and specificity detecting ID among African women living at 1700 m above sea level. cross-sectional study 492 18-25-year-old women, we status biomarkers. Using receiver operating characteristic curves,...
Vitamin D deficiency and anemia impact the health of women reproductive age. Evidence suggests an inverse relationship between serum vitamin (25-hydroxyvitamin [25(OH)D]) anemia/iron deficiency, but less is known about these associations in age, particular a setting with combined burden micronutrient food insecurity, obesity.
The prevalence of anaemia among South African women reproductive age (WRA) remains high at 39%. Multiple micronutrient supplementation (MMS) may be an effective strategy in the prevention and management anaemia. Our aim was to understand facilitators barriers preconception MMS adherence explore perceptions beliefs treatment non-pregnant WRA. This qualitative study embedded a intervention trial WRA conducted two phases. Phase one assessed adherence. Individual interviews were with community...
South Africa (SA) launched their 24-h movement guidelines for birth to five years in December 2018. The guideline dissemination plan adopted a “train-the-trainer” strategy through workshops with community-based organisations (CBOs) working early childhood development. aim of this paper is to: (1) document process; and (2) report on the feasibility implementing workshops, acceptability (and guidelines) different end-user groups, extent which CBO representatives disseminated end-users. Fifteen...

Abstract Introduction In South Africa, public perceptions of the COVID-19 pandemic and risk mitigation measures remain mixed. To better understand health behaviours in context COVID-19, a qualitative study was conducted, which aimed to investigate relating among African adult population. Methods Twelve online focus groups were conducted across following age groups: 18–34, 35–54, 55 + years old (total n = 70) December 2021. Diversity socioeconomic status, geographical areas, urban rural...
Abstract Background – Anaemia continues to be a major public health problem among women of reproductive age (WRA). A thorough understanding anaemia risk factors is necessary design better interventions. This paper examines the determinants WRA in South Africa. Methods - We included baseline data from 480 participating pilot-phase randomized controlled trial (HeLTI). measured haemoglobin (Hb) status using Hemocue. Plasma iron markers (ferritin and soluble transferrin receptor (sTfR)),...
