In South Africa, urbanisation is associated with substantial burdens of adolescent overweight and obesity, making teenagers vulnerable to longer-term non-communicable diseases. In addition, as potential future parents, the nutritional status of adolescents is increasingly recognised as a key driver of health and well-being in the next generation. This review reported on the available literature examining nutritional status and dietary intakes and practices, as well as their determinants, in South African adolescents. Study design and methods: Medline (Pubmed), Web of Science and EMBASE were searched for relevant articles published between 1994 and May 2018. Applicable search terms and phrases were identified in study titles and/or abstracts and fulltext articles were reviewed according to inclusion/exclusion criteria. Data were extracted according to specific review objectives. Results: A total of 67 relevant studies were identified. Only one study used a biochemical marker to describe adolescent nutritional status (vitamin D status; 25(OH)D). Overweight and obesity prevalence increased in South African adolescents over the reference period, with national increases of 6% in boys and 7% in girls between 2002 and 2008. Girls and urbandwellers were particularly vulnerable to excess adiposity. Dietary intakes demonstrated a transition towards energy-dense, processed foods high in sugar and fat, but low in essential micronutrients. Food choices were driven by the adoption of obesogenic behaviours in the teenage years, including irregular breakfast consumption and fewer family meals, increased snacking and low levels of physical activity. Conclusion: South African adolescents-particularly girls-are increasingly burdened by obesity as a result of urbanisationassociated shifts in dietary intake and eating behaviours. However, the implications for micronutrient status and long-term nutritional health are not known. Additionally, more data on the clustering of diet, activity and sedentary behaviours in adolescent boys and girls is needed, as well as on behaviour patterns to facilitate healthy growth and reduced adiposity.

“…The only national survey in children was undertaken in 1999, the National Food Consumption Survey (NFCS), with no follow up for comparison to show trends and changes in diet [15]. Evidence from numerous local studies in South Africa with children and adolescents in both urban and rural areas suggests increases in fat, sugar and salt, due to consumption of energy dense snacks, fast food consumption, and sweetened beverages [16][17][18][19]. The Provincial Dietary Intake Study (PDIS) is a follow-up of the NFCS study in two rapidly urbanizing provinces.…”

The double burden of malnutrition is still prevalent in South Africa, hence the importance of a dietary survey to identify risks of under-and over-nutrition. A multistage stratified cluster random sampling design was applied in two economically active provinces, Gauteng (GTG) (N = 733) and Western Cape (WC) (N = 593). Field workers completed questionnaires, and a 24 h recall with children taking part aged 1-<10-years (N = 1326). Important findings were that 71% and 74%, respectively, of 3-<6-year-olds and 6-<10-year-olds had an energy intake below the estimated energy requirement (EER), while 66% 1-<3-year-olds had intakes above the EER. The percentage of children with a total fat intake below recommended levels decreased as age increased ((51%, 40% and 5%) respectively, for the three age groups). Similarly, the percentage of those who had a total fat intake above the recommendation increased with increasing age (4%, 11% and 26%, respectively, for the three age groups). Saturated fat intake above 10%E was highest in the youngest and oldest children (33% and 32%, respectively). The percentage of children with a free sugars intake above 10%E was 47%, 48% and 52% respectively, and 98-99% had a fibre intake that was less than recommended. Overall, the diet was not healthy, with the main food items being very refined, and the diet being high in salty snacks and sugary items, and low in fruit, vegetables and legumes. non-communicable diseases (NCDs) [6,7]. Rapid weight gain in infancy is also associated with long-term risk of adult weight gain and development of NCDs [8].In a recent publication of the same children whose dietary results are studied here, nutritional status by means of anthropometry was determined [9]. Stunting was found to be 39% and 23% in 1and 2-year-olds, respectively. Overweight and obesity were found to be 23% and 14% in 1-year-olds, and 11% and 9% in 2-year-olds, and those who were both stunted and overweight were 19% and 6%, respectively, in 1-and 2-year-old children. The double burden of malnutrition is clearly illustrated.The double burden of malnutrition is commonly found in many low-and middle-income countries [10] and much of this can be largely attributed to the nutrition transition taking place, in conjunction with decreased levels of physical activity [10]. The nutrition transition implies moving from a traditional diet which is high in carbohydrate and fibre and low in sugar and fat to a more contemporary Western diet which is high in fats, saturated fats, sodium and sugar [11]. One of the main drivers of this transition is urbanization [10,12].A recent review of dietary studies in developing countries by Ochola and Masibo showed what the typical dietary scenario in developing countries is [13]. This review included 50 studies from 42 countries in children and adolescents. The findings were an overall low energy intake, lack of dietary diversity, low intake of fruit and vegetables and micronutrient deficiencies. At the same time the emerging nutrition transition is stressed. This includ...
