Design: This was a cross-sectional survey. Setting: The University of Pretoria (UP) was the site of the survey. Population: The study encompassed first- (2012–2015) and third- (2012–2017) year female dietetics students (N = 368). Outcome: Dietary intake data from multiple-day weighed food records were analysed on nutrient, food group and meal and snacking pattern levels. Results: Recorded energy intakes of participants (n = 105 first years, n = 166 third years; response rate: 73.6%) were below Estimated Energy Requirements. Across year groups, intakes exceeded and fell below the Acceptable Macronutrient Distribution Range for fat and carbohydrates respectively; however, third years consumed cereals, grains and starchy vegetables more often. Over 50% of first and third years exceeded Estimated Average Requirements of respectively 3 and 6 of 10 tested micronutrients. Third years recorded higher (all p < 0.001) intakes of protein, magnesium, calcium, zinc and vitamin A than first years. Similarly, their Nutrient Adequacy Ratios were higher (all p < 0.001) for magnesium, calcium and vitamins A, B6 and B12. Average Mean Adequacy Ratios were 70% (first years) and 77% (third years). The year groups differed in terms of food group intake. The number of daily eating occasions decreased over weekends for first and third year students, yet intakes of energy (p < 0.05) and fat (p < 0.001) were higher over weekends. Conclusions: Amidst likely under-recording and/or under-eating, UP female dietetics students’ intakes of some micronutrients may be low. Recorded intakes of third years exceeded those of first years. Recorded nutrient intake improved from the first to the third year of the study in dietetics students.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"142 - 148"},"PeriodicalIF":1.1,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45476084","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}

The Acute Care Hospital Foodservice Patient Satisfaction Questionnaire was administered. Meals were weighed before and after consumption to calculate energy and protein intake per patient/day. \u0000 Results:\u0000 A total of 128 patients (males = 71) participated. Total protein served did not meet patient requirements in any of the hospitals. Consumed energy and protein were significantly below requirements in all hospitals (p < 0.002). Perceived food quality (r = 0.38, p = 0.039) and staff/service issues (r = 0.39; p = 0.035) were significantly positively correlated with protein intake, while appetite correlated positively (r = 0.42, p = 0.006; r = 0.41, p = 0.008) and length of stay (LOS) correlated negatively (r = −0.46, p = 0.002; r = −0.42, p = 0.008) with energy and protein intake, respectively. \u0000 Conclusion:\u0000 Energy and protein served was significantly lower than participants’ requirements in all three hospitals and none achieved the official ration scale amounts. Nearly 40% reported having a normal appetite and did not receive additional food from family or friends, which may lead to hospital-acquired malnutrition and increased hospital length of stay (LOS). Improved hospital food quality, quantity, mealtimes and staff training should be a focus to improve patient energy and protein intake.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"133 - 141"},"PeriodicalIF":1.1,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45959392","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}

Subjects: A total of 359 adult participants were included in this study. Outcome measures: Objective understanding was measured by asking participants to rank food products according to their nutritional quality, using the displayed front-of-pack label. Results: The type of front-of-pack label significantly influenced ranking ability (p < 0.00001). All the evaluative front-of-pack labels significantly improved the participants’ ability to identify healthier food products compared with the no-label control. The reductive Reference Intake, however, showed no significant impact on consumer understanding. Conclusion: Evaluative front-of-pack labels significantly improved the participants’ ability to identify healthier food products, when compared with the Reference Intake and no-label control.

Design: A rapid-assessment mixed-methods approach using qualitative and quantitative studies was adopted. Secondary data sources supported in-field findings. Setting/Subjects: Qualitative approaches included 17 key informant interviews from 7 SADC member states. Quantitative methods of an online survey elicited feedback from 61 participants from 11 SADC member states. Outcome measures: More strategic, best practice, infant and young child feeding SBCC programmes are recommended in SADC. Results: Programme challenges included increased demands on health systems from Covid-19, poor attitudes and beliefs toward IYCF behaviours, the dual burden of undernutrition and overnutrition, and financial and human resource capacity challenges to implement and evaluate SBCC campaigns at scale. Opportunities were also identified for improved detection, better meeting IYCF nutritional needs from locally sourced foods, training and capacity building for greater engagement of front-line field staff, effective policy development to support parent-friendly hospitals and workplaces, and improved regional integration. Conclusions: The needs assessment demonstrated that priority programme planning can continue while the health sector deals with a pandemic threat. The adaptation to virtual support provided a variety of learnings for research designs, data collection and analysis, albeit over an extended timeframe of six months. A number of innovative approaches were identified in the resultant SBCC strategy for SADC along with opportunities for regional efficiencies in adapting existing, best practice SBCC creative and programming approaches.","PeriodicalId":45938,"journal":{"name":"South African Journal of Clinical Nutrition","volume":"35 1","pages":"115 - 121"},"PeriodicalIF":1.1,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42529214","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, 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":"35 1","pages":"100 - 107"},"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":"35 1","pages":"94 - 99"},"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":"35 1","pages":"88 - 93"},"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":"34 1","pages":"S41 - S50"},"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}
