    Are the attitudes and practices of foodservice managers, catering personnel and students contributing to excessive food wastage at Stellenbosch University?
    (Co-published by Medpharm Publications, NISC (Pty) Ltd and Taylor & Francis Group, 2017) Marais, M. L.; Smit, Y.; Koen, N.; Lotze, E.
    Objective: The aim was to investigate factors contributing to food wastage by Stellenbosch University (SU) students in selected residences, and to determine the attitudes and practices of students and catering personnel impacting on food waste and a sustainable environment. Design: Cross-sectional, descriptive study. Setting: Stellenbosch University, Western Cape. Subjects: Six foodservice managers, 63 catering personnel and 517 students participated in the study. Outcome measures: A weighed-food wastage study was conducted at seven selected residences during lunch and supper on three non-consecutive weekdays. Food service managers (FSMs) and catering personnel completed interviewer-administered questionnaires, while SU students completed an electronic survey. Results: Ninety percent of students preferred the standard menu options, despite a relatively high average plate waste of 16.9%. More production waste was generated during lunch than supper. The male residence generated more plate waste. Even though students requested larger servings of vegetables, the wastage of these items was high. Factors contributing to wastage were the booking system, menus and serving style, meal plan stipulating the serving of dessert and serving of a large starch portion. All FSMs and 88.5% catering personnel considered it important to reduce food wastage to a minimum. Conclusion: Education of catering personnel and students regarding food waste reduction measures is crucial. A representative forum including students, catering companies and faculty management should be involved when seeking solutions to reduce food wastage and improve communication. By implementing these strategies, a university-wide culture of sustainability with a focus on food waste reduction can be developed and nurtured.

    Assessing the knowledge and perceptions of medical students from the Western Cape, South Africa, regarding the Millennium Development Goals
    (Medpharm Publications, 2012) Yeatman, Toni-Lee; Koen, N.; De Ridder, L.; Fenn, B.; Wormsbacher, L.; Daniels, L.
    Background: Health science students are key players in implementing the Millennium Development Goals (MDG). Knowledge and understanding at university level is essential to achieve the goals by 2015. The primary objective of this study was to assess the knowledge and perceptions of fifth-year medical students at Stellenbosch University and the University of Cape Town regarding the MDG. The secondary objectives were to determine the degree to which students are involved in awareness campaigns and implementation of the MDG, and to assess students’ perceptions regarding the need for the MDG in South Africa. Method: This observational, descriptive, cross-sectional study collected quantitative data. A census was carried out. All participants completed a self-administered questionnaire. Results: Of the 176 participants, 61.14% said they had previously heard or read about the MDG. Forty per cent had heard about the MDG through awareness campaigns. More than half (54.86%) claimed to know what the MDG were, but could not name all of the goals. Participants identified a mean of three out of eight MDG correctly. The majority of students considered MDG implementation in South Africa important but ineffective (69.85%), and 85.82% believed that the MDG would not be achieved on time. Conclusion: It was found that fifth-year medical students in the Western Cape were not adequately informed about the MDG and their importance in South Africa. However, their perceptions were positive, in that the majority agreed that the implementation of the MDG in South Africa is important and that more needs to be done in creating awareness about the goals.

    Assessing the utilization of a child health monitoring tool
    (Health and Medical Publishing Group, 2017) Blaauw, Renee; Daniels, L.; Du Plessis, L. M.; Koen, N.; Koornhof, H. E.; Marais, M. L.; Van Niekerk, E.; Visser, J.
    Objective: The study assessed the implementation of growth monitoring and promotion, immunisation, vitamin A supplementation, and deworming sections of the Road-to-Health Booklet. Caregivers and health care workers knowledge, attitudes and practices were investigated as well as health care workers perceptions of barriers undermining implementation. Methods: A cross-sectional descriptive study was conducted on a proportional sample of randomly selected Primary Health Care facilities across six health districts (35%; n=143) in the Western Cape Province. Health care workers involved in the implementation of the Road-to-Health Booklet, children (0-36 months) and CGs were included. Information was obtained through scrutiny of the Road-to-Health Booklet, observation of consultations and structured questionnaires. Results: A total of 2442 children, 2481 caregivers and 270 health care workers were recruited. Weight (94.7%) measurements were performed routinely. Less than half (40.2%) of caregivers reported that their child’s growth was explained. Sixty-eight percent of health care workers correctly identified criteria for underweight, whereas only 55% and 39% could do so for stunting and wasting respectively. Road-to-Health Booklet sections were completed adequately for immunization (89.3%), vitamin A supplementation (94.6%) but not for deworming (48.8%). Most health care workers (94%) knew the correct regimes for vitamin A supplementation and deworming, but few caregivers knew when treatment was due for vitamin A supplementation (16.4%) and deworming (26.2%). Potential barriers identified related to inadequate training, staff shortages and limited time. Conclusion: Focussed effort and resources should be channelled towards health care workers training and monitoring regarding growth monitoring and promotion to optimize utilization of the Road-to-Health Booklet. Mobilisation of community health workers is needed to strengthen community awareness of preventative health interventions.

    The barriers that women face when choosing food for their primary school children : a case study in the Western Cape Province, South Africa
    (Health and Medical Publishing Group, 2017) Smit, Y.; Kassier, S.; Nel, D.; Koen, N.
    Background. Unhealthy food choices made by mothers can impact negatively on child health and may lead to unhealthy eating behaviours that persist into adulthood. Choosing food is a complex process influenced by many factors. Objectives. To determine the factors that influence mothers’ food choices and to investigate barriers to purchasing healthy food. Methods. A cross-sectional, descriptive study, with an analytical component, was conducted. Mothers (N=476) were recruited from three randomly selected primary schools, from a low, middle and high quintile. A self-administered questionnaire was used to collect data on demographics, knowledge, attitude and practices of mothers. Six focus groups (FG) (two per school) were conducted to investigate the factors that prevent mothers from making healthy dietary decisions. Results. The mean nutrition knowledge score for the group was 68.6%. Nutrition knowledge was significantly lower (p<0.01) in mothers from the lower quintile school (64.0%). Primary factors influencing food purchases were cost (60%), nutritional value (37%) and time constraints (29%). Primary sources of nutrition information included magazines and health professionals at 62% and 44%, respectively. Time constraints resulted in mothers purchasing convenience foods more often (p=0.001). The main barriers identified were mixed media messages, the school environments and supermarket layouts. Conclusion. Nutrition education campaigns should include practical advice, e.g. the preparation of economical, wholesome meals. Policymakers should monitor increasing prices of healthy foods. School and supermarket environments, as well as the food industry, can play a pivotal role in facilitating mothers to make healthy food choices

    Food and nutrition labelling : the past, present and the way forward
    (MedPharm Publications, 2016) Koen, N.; Blaauw, Renee; Wentzel-Viljoen, E.
    Current global mortality from noncommunicable diseases (NCDs) remains unacceptably high and is increasing. A major reduction in the burden of NCDs should come from population-wide interventions, including the promotion of a healthy diet through the provision of adequate nutrition information on food labels. However, in order for this type of intervention to be successful, it is important to have a better understanding of the consumer. This review focuses on the need for food and nutrition labelling (the section of information on a food label that specifically declares nutrient content) within the context of NCDs, as well as consumer nutrition label use, and understanding and the impact of nutrition labelling on purchasing behaviour. It provides a summary of the latest global nutrition labelling trends, the current situation in South Africa and the way forward. Consumer knowledge, use and understanding of nutrition labelling has been investigated extensively in the international literature. However, the majority of these investigations were conducted in developed countries. Therefore, additional research on the impact of nutrition labelling in developing countries is necessary, and should be a priority. There have been many developments in South Africa in terms of food and nutrition labelling in the last decade. Although the food industry, health professionals and consumers face many changes, challenges and opportunities with regard to food, and specifically to nutrition labelling, this is also the ideal time to promote the use and understanding of nutrition information on labels by health professionals to consumers.

    Perceptions of dietitians and key role players regarding their role in reporting food labelling transgressions in South Africa
    (Taylor & Francis Group, 2024-05-16) Profe-Fuchsloch, Mikayla; Koen, N.; Wicks, M.
    Objectives: A study was undertaken to describe South African dietitians and key role players’ perceptions regarding their role in reporting food labelling legislation transgressions. Design: A multimethod study design was employed to explore a previously unstudied topic. Setting: Dietitians registered with the Health Professions Council of South Africa (HPCSA) together with key role players in food labelling in South Africa. Methods: Quantitative data were collected using a self-administered electronic questionnaire and qualitative data using a semi-structured interview guide. Quantitative data were analysed using Microsoft Excel and qualitative data using ATLAS.ti software. Data were analysed independently in the results section but integrated for interpretation of the findings. Results: In total, only 6% (n = 7) of the included dietitians (n = 126) reported food labelling transgressions, and 12% (n = 15) believed dietitians have a role to play in reporting transgressions. Interestingly, half of the included dietitians (50%, n = 63) stated they would report an identified transgression. Dietitians demonstrated a lack of awareness of the current food labelling regulations, with 43% wrongly identifying the draft regulation to consult. Almost all (99%, n = 125) of the included dietitians reported that their transgression reporting practices would improve if a clear guideline from the Department of Health: Directorate Food Control (DoH DFC) was available. Key role players (n = 8) cited enforcement issues and a perceived gap in dietitians’ understanding of legislation and reporting processes as barriers to reporting non-compliance. Key role players identified enablers such as awareness of regulations, contacts within the DoH DFC and familiarity with the reporting process for transgressions. They also provided insight on the proper procedure for reporting food labelling transgressions. Conclusion: The low prevalence of food labelling transgression reporting by dietitians stems from several barriers, including a perceived lack of confidence regarding the current regulation, awareness of the applicable legislation, uncertainty regarding the correct reporting procedure and scepticism that transgression reports will be acted upon. Regular communication regarding food and nutrition regulations and the development of an easy-to-use transgression reporting framework could support the implementation and impact of food labelling regulations in South Africa.
