Design, setting and subjects: A cross-sectional survey and interviews with mothers and caregivers from the KwaMashu Community Health Centre were conducted. One hundred and thirty-four interviews were completed. This information provided the food consumption input for the model using Optifood software. Results: The results revealed that with the current food pattern of infants from the study group in KwaMashu, iron, zinc and calcium are nutrients whose requirements are likely not to be met in the diet. The percentage RNI (recommended nutrient intake) for iron was 25.2%, zinc 51.3% and calcium 77%. Nutrient intakes for these nutrients of concern improved in the ‘No pattern’ diet but iron and zinc intakes remained below the RNI. According to the best diets modelled by Optifood, it appears that infants in KwaMashu would be able to achieve the recommended intakes of energy, protein, and 8 of the 11 micronutrients, as long as breastfeeding on demand continues during the complementary feeding phase. Conclusions: This study calls into question the continued food-based focus to ensure nutrient adequacy in infants. In conjunction with efforts to improve household food security and continued support and promotion of breastfeeding for the first 2 years of life, targeted micronutrient supplementation may be needed to ensure the optimal growth and development of infants in South Africa.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43880414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design A cross-sectional, descriptive study was conducted. Setting Dietitians who were registered with the Health Professions Council of South Africa (HPCSA), and working in the province of KZN at the time of the study, were invited to participate. Methods Data were collected using a self-administered electronic questionnaire distributed through SurveyMonkey, an Internet-based survey programme. Results Dietitians agreed that carbohydrate counting was a useful dietary management approach for diabetes (p < 0.05) and that it was essential to manage T1DM (p < 0.05). However, they felt it was a difficult concept for patients with T1DM to understand (p = 0.001) and teaching it to patients was time consuming (p < 0.05). Although dietitians believed that there was a strong evidence base for teaching carbohydrate counting to patients with T1DM (p < 0.05), they indicated a need for further training or education in it (p < 0.05). Barriers to using carbohydrate counting included a lack of training, confidence and experience, financial resources, time, blood glucose records and poor patient motivation and patient illiteracy (p < 0.05). Conclusions Overall, dietitians who participated in the study had a positive perception towards the use of carbohydrate counting in the management of T1DM. However, further training needs to be addressed for carbohydrate counting to be used with confidence by dietitians in KZN to optimize their management of T1DM.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44777741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, there has been a reported association of 25(OH)D with BMI, BP and lipid levels in some cross-sectional and longitudinal studies. Methods: This is a longitudinal study of a group of adolescents with measurements of 25(OH)D, BP, anthropometry and lipids at the ages of 11, 12 13, 15 and 18–20 years. For age-related changes, year 12 participants (n = 261) were matched with year 18–20 participants (n = 368), resulting in 200 paired participants. Longitudinal analyses using the Generalized Estimating Equations (GEE) comprised the following groups of participants, Year 11 (n = 288), Year 12 (n = 253), Year 13 (n = 292), Year 15 (n = 238) and Year 18–20 (n = 368). The relationship of 25(OH)D with BMI, BP and lipid levels over a period of 10 years was assessed. Results: There were significant increases in mean BMI and BP, and decreases in 25(OH)D levels with age (all p-values < 0.0001). In females, systolic BP was significantly higher in older participants (18–20) years than younger participants (12 years), but 25(OH)D was significantly higher in younger than older participants. In males, there was significant increase in BP in participants between age 12 years and 18–20 years. 25(OH)D, total cholesterol (TC) and low-density lipoprotein (LDL-C) were significantly lower in 18–20-year-old participants compared with 12-year-old participants. Longitudinally, 25(OH)D was inversely associated with LDL-C. Conclusion: There is evidence of changes in 25(OH)D, BMI and BP in adolescents over a period of 10 years. After adjusting for covariates, BMI and LDL-C were significantly negatively associated with 25(OH)D, which suggests that vitamin D status might be associated positively with favourable lipid profiles in children and adolescents.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44037960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food Based Dietary Guidelines (FBDGs) for the SA elderly were developed to address this need. These thirteen guidelines for the elderly collectively offer a basis of health practices that the elderly can follow to ensure that they are taking the right steps toward maintaining their health. While the guideline ‘Eat clean and safe food’ is not included in the current SA FBDGs, this recommendation is of particular importance to the elderly, who face a much higher risk of foodborne illness than most of the general population due to a number of factors. Reduced immunity and other physiological changes are a result of ageing, malnutrition, diseases and and/or medication side effects. All these factors play a role in the elderly’s risk of foodborne illness. Increased susceptibility to certain pathogens also causes higher rates of foodborne illness infection. Lastly, elderly people’s food safety knowledge and pre-established beliefs and practices regarding food handling and preparation can be influential in their sensitivity to foodborne disease. These risk factors, coupled with the heavy burden of foodborne illness and existing gaps in food safety policy, practices and education in SA, substantiate the need for a dietary guideline to address the importance of clean and safe food consumption among the elderly in SA.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44037790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

South Africa (SA) currently has two sets of guidelines, namely the paediatric food-based dietary guidelines and the South African FBDGs for the population aged seven years and older.

Water is essential for life and is necessary for important functions of the body like maintenance of tissue structure, blood volume regulation, temperature regulation and excretion of metabolites through kidneys. Though water is necessary for all, the elderly are especially at risk of dehydration due to altered hormonal activity and body functions that reduce their sensitivity to thirst (water intake) and urination (water excretion). Total body water is also reduced in the elderly, so they are unable to buffer the effects of water loss in the body. Therefore, water intake should be monitored properly in the elderly so that they can lead a happy and healthy life and reduce the economic burden due to hospitalisation caused by water imbalance or dehydration, which is common in the elderly. Two litres of water per day is generally considered adequate, but there is no consensus regarding the exact requirement for water as need varies due to climate and physical activity levels. The importance of water to maintain bodily functions and the risk of dehydration substantiate the need for a dietary guideline to address the importance of clean and safe water/fluid consumption regularly throughout the day among the elderly in SA.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46393339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous publications encouraging alcohol use have referred to two supposedly beneficial effects of alcohol, categorised as: (1) cardioprotective and haemostatic; and (2) promoting a positive balance in iron status. However, more recent evidence has weakened these assertions for all age groups as the disadvantages of alcohol use far outweigh these benefits. Some of these disadvantages can cause severe medical and physical harm to the elderly. Attempts to curb risky drinking among the SA elderly must be adopted through screening by clinicians during consultations, use of various screening and diagnostic tools available for addressing alcohol use and abuse, and exploiting the channels of alcohol exposure for appropriate interventions. Elderly populations are vulnerable to alcohol misuse irrespective of their consumption patterns or levels of use because of their ageing condition and the interaction of alcohol with medication. Therefore, there is a need to sensitise the SA elderly population on the risk posed by alcohol use, misuse or abuse, hence the FBDG ‘If you drink alcohol, drink sensibly’.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47202514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
