    (World Health Organization -- WHO, 2017-4) Delisle, Helene; Shrimpton, Roger; Blaney, Sonia; Du Plessis, Lisanne; Atwood, Stephen; Sanders, David; Margetts, Barrie
    INTRODUCTION: Neglected for several decades, nutrition is now firmly on the development agenda. Important landmarks are the initiation of the Scaling Up Nutrition movement in 2010; the adoption by the World Health Assembly of the Comprehensive Implementation Plan for Maternal, Infant and Young Child Nutrition in 2014; and the World Health Organization’s (WHO) Global Action Plan for the Prevention and Control of Noncommunicable Diseases for 2013–2020. Public health nutrition has to meet multiple new challenges, including the shift from the millennium development goals to the sustainable development goals (SDGs), together with growing issues such as climate change, globalization, urbanization, socioeconomic disparities, migration and wars.

    (Stellenbosch : University of Stellenbosch, 2007-12) Du Plessis, Lisanne; Marais, D.; Labadarios, D.; Singh, T.; University of Stellenbosch. Faculty of Health Sciences. Dept. of Interdisciplinary Health Sciences. Human Nutrition.
    Introduction In order to address poor breastfeeding rates, both nationally and internationally, there is a great need for ongoing breastfeeding training for students of health care professions and health care workers (HCWs). Despite the availability of courses, there is a need for new approaches to ensure greater and more effective coverage in breastfeeding training. The students of today relate well to the use of computers in the learning environment. It was therefore deemed appropriate to explore this training method as a means to enhance the breastfeeding learning experience for students of health care professions and, more specifically, for undergraduate dietetic students. This study was aimed at adapting and validating an Indian computer-based undergraduate breastfeeding training module, intended for use by South African (SA) undergraduate dietetic students, in order to assess whether computer-based learning in breastfeeding training could address the relevancy of the topic, assess how students view the learning experience and determine whether it could contribute to a gain in knowledge of the subject. Methods An Indian computer-based undergraduate breastfeeding training module in PowerPoint format was adapted to suit the SA scenario. It was converted into web-based interactive material using the Virtual Training Studio (VTS) software tool. The adapted module was assessed for face and content validity by 19 peer reviewers and 17 third year Stellenbosch University (SU) dietetic students, by means of a self-administered questionnaire. A focus group discussion was also conducted with the third year students. The impact of the adapted module on knowledge was evaluated by means of a pre- and post-knowledge test on a total of 29 second year SU (n=14) and University of the Western Cape (UWC, n=15) dietetic students. Results All of the peer reviewers and students were of the opinion that their information technology (IT) skills were sufficient to complete the adapted module. The majority of the peer reviewers (94%, n=17) also indicated that they had adequate IT facilities and that it was feasible to administer the module. Peer reviewers and students enjoyed the presentation and delivery mode of the adapted module. Third year students indicated that computer-based learning (CBL) was a “nice way of learning”, but pleaded that it should not be used as the sole source of instruction. The majority of the peer reviewers and students (53%, n=19) rated the mode of learning to be equally effective compared to conventional lectures, 35% rated it as being more effective and 11% as less effective. Eighty six percent of peer reviewers and students felt that the information in the adapted module was sufficient to enable the students to take the necessary preventive- or treatment action. The majority (91%) were of the opinion that the information in the adapted module was appropriate for the specific needs and cultural context in SA. There was a significant increase in the knowledge test scores for second year students at SU and UWC. Conclusion The SA VTS breastfeeding training module can be integrated effectively as part of multi-media methods to increase knowledge and enhance breastfeeding training for undergraduate dietetic students, as well as other students of health care professions and, possibly, HCWs in institutions striving to become Baby Friendly.

    Effects of agricultural biodiversity and seasonal rain on dietary adequacy and household food security in rural areas of Kenya
    (BioMed Central, 2015) M'Kaibi, Florence Kithira; Steyn, Nelia P.; Ochola, Sophie; Du Plessis, Lisanne
    ENGLISH SUMMARY : Background: Kenya has a high prevalence of underweight and stunting in children. It is believed that both agricultural biodiversity and seasonal rainfall influences household food security and dietary intake. In the present study we aimed to study the effects of agricultural biodiversity and seasonal rains on dietary adequacy and household food security of preschool Kenyan children, and to identify significant relationships between these variables. Methods: Two cross-sectional studies were undertaken in resource-poor households in rural Kenya approximately 6 months apart. Interviews were done with mothers/caregivers to collect data from randomly selected households (N = 525). A repeated 24-hour recall was used to calculate dietary intake in each phase while household food security was measured using the Household Food Insecurity Access Scale (HFIAS). A nutrient adequacy ratio (NAR) was calculated for each nutrient as the percent of the nutrient meeting the recommended nutrient intake (RNI) for that nutrient. A mean adequacy ratio (MAR) was calculated as the mean of the NARs. Agricultural biodiversity was calculated for each household by counting the number of different crops and animals eaten either from domestic sources or from the wild. Results: Dietary intake was low with the majority of households not meeting the RNIs for many nutrients. However intake of energy (p < 0.001), protein (p < 0.01), iron (p < 0.01), zinc (p < 0.05), calcium (p < 0.05), and folate (p < 0.01) improved significantly from the dry to the rainy season. Household food security also increased significantly (p < 0.001) from the dry (13.1 SD 6.91) to the rainy season (10.9 SD 7.42). Agricultural biodiversity was low with a total of 26 items; 23 domesticated and 3 from the natural habitat. Agricultural biodiversity was positively and significantly related to all NARs (Spearman, p < 0.05) and MAR (Spearman, p < 0.001) indicating a significant positive relationship between agricultural biodiversity of the household with dietary adequacy of the child’s diet. Conclusion: Important significant relationships were found in this study: between agricultural biodiversity and dietary adequacy; between agricultural biodiversity and household food security and between dietary adequacy and household food security. Furthermore, the effect of seasonality on household food security and nutrient intake was illustrated.

    Evaluation of selected aspects of the Nutrition Therapeutic Programme offered to HIV-positive women of child-bearing age in Western Cape Province, South Africa
    (AOSIS Publishing, 2015-04-28) Hansen, Tine T.; Herselman, Marietjie; Du Plessis, Lisanne; Daniels, Luzette; Bezuidenhout, Tirsa; Van Niekerk, Cora; Truter, Laura; Iversen, Per O.
    Background: The Nutrition Therapeutic Programme (NTP) involves the provision of food supplements at primary health clinics (PHCs) to correct nutritional deficiencies in vulnerable groups. Although previous studies have identified problems with implementing the programme at PHCs, assessments of its efficiency have been scarce. Objective: To evaluate implementation of the NTP at PHCs that provide antiretroviral therapy. Methods: A cross-sectional, descriptive study was conducted at 17 PHCs located within 3 districts of Western Cape Province. Two target groups were chosen: 32 staff members working at the sites and 21 women of child-bearing age enrolled in the NTP. Questionnaires were used to obtain data. Results: Only 2 women (10%) lived in food-secure households; the rest were either at risk of hunger (29%) or classified as hungry (61%). Most of the women knew they had to take the supplements to improve their nutritional status, but the majority only recalled receiving basic nutritional advice, and the information was mainly given verbally. Ten of the women had shared their supplements with others, mostly with their children. The study identified lack of clearly defined NTP responsibilities at the PHCs, causing confusion amongst the staff. Although many staff members expressed problems with the NTP, only 38% of them reported having routine evaluations regarding the programme. Conclusion: Several aspects compromised the effectiveness of the NTP, including socioeconomic factors leading to clients’ non-compliance. The strategic organisation and implementation of the NTP varied between different PHCs offering antiretroviral therapy, and staff experienced difficulties with the logistics of the programme.

    Selected facets of nutrition during the first 1 000 days of life in vulnerable South African communities
    (Health & Medical Publishing Group, 2016-03) Du Plessis, Lisanne; Herselman, Martha G.; McLachlan, Mildred H.; Nel, Johanna H.
    Background. Optimal nutrition during the first 1 000 days of life can reap lasting benefits throughout life. Objectives. To assess infant and young child-feeding (IYCF) practices and mother/caregiver-child anthropometry in two vulnerable Breede Valley communities, Western Cape. Methods. Mothers of children aged 0 - 23 months (N=322) were interviewed to assess IYCF practices. Anthropometric measurements of mothers/caregivers and children were performed according to standard procedures. Results. Mothers reported early breastfeeding (BF) initiation in 75.2% (242/322) of cases. Of infants <6 months old, 38.5% (45/117) were recorded as exclusively breastfed (EBF). Cross-checking this figure with other research from the area, however, suggests significant over-reporting of EBF. One in five infants <6 months were exclusively bottle fed (19.7%; 23/117) and 48.4% (156/322) aged 0 - 23 months had received bottle feeding in the preceding 24 hours. Eighty-four percent (36/43) of 6 - 8-month-old infants were receiving complementary foods. BF was continued in 32.5% (13/40) of children 12 - 15 months old. In children 6 - 23 months, 44.0% (90/205) received foods from four or more food groups, 71.0% (145/205) received complementary foods the recommended minimum number of times or more, and 44.4% (91/205) received a minimum acceptable diet. The prevalence of stunting and overweight in children was 28.9% and 21.8%, respectively. The prevalence of overweight in mothers/caregivers was 28.9%, and 33.7% were obese, with a mean waist circumference of 88.6 cm. Conclusion. Indicators showed sub-optimal IYCF practices with child under- and overnutrition coexisting with maternal/caregiver overnutrition. This profile signals a need for urgent and appropriate interventions focusing on the first 1 000 days of life.
