Decreased frequency of sugar-sweetened beverages intake among young children following the implementation of the health promotion levy in South Africa
Objective: This study assessed the association between baseline sociodemographic variables, body composition and 4-year changes in the intake of food groups, including sugar-sweetened beverages (SSB) among children, after the implementation of the health promotion levy. Design: Prospective cohort study. Setting: Ten schools in North West Province, South Africa. Participants: 950 children aged 5–9 years at baseline and data of 672 children at foll…
Nutrient intake of young South African adults from the baseline of the African-PREDICT cohort study
Objective: This study aimed to describe and compare the nutrient intake of young adults in the African Prospective Study on the Early Detection and Identification of Cardiovascular Disease and Hypertension (African-PREDICT) study according to ethnicity and socio-economic status (SES). Design: Cross-sectional analysis of baseline nutrient intakes in the African-PREDICT study. Setting: North West Province, South Africa Participants: Black and white…
The association between an energy-adjusted dietary inflammatory index and inflammation in rural and urban Black South Africans
Objective: To quantify the inflammatory potential of the diet of rural and urban Black South Africans using an adapted energy-adjusted dietary inflammatory index (AE-DII) and to investigate its relationship with inflammatory and cardio-metabolic disease risk markers. Dietary inflammatory potential has not been investigated in African populations. Design: Cross-sectional investigation. Setting: Rural and urban sites in the North West province of S…
Associations of dietary diversity with anaemia and iron status among 5- to 12-year-old schoolchildren in South Africa
Objective: To examine the associations of dietary diversity with anaemia and iron status among primary school-aged children in South Africa. Design: An analysis was conducted with pooled individual data from the baseline surveys from three previously conducted independent intervention studies. Two different dietary diversity scores (DDS) were calculated based on data from 1-day (1-d) and 3-day (3-d) dietary recall periods, respectively. Logistic …
