Text in English with abstracts in English, Venda and Sepedi / Background: Suitable complementary feeding practices in young children can ensure optimal nutrition status and reduce under 5 mortality rates (Jones et al., 2014). Inadequate dietary diversity (DD) of the complementary diet both in quality and quantity is one of the major problems affecting infants and young children worldwide (Ntila et al., 2017). Adequate and appropriate nutrition during infancy and early childhood is vital for the growth and development of every child to reach full human potential (PAHO, 2003; WHO, 2008a; UNICEF, 2016). Nutritional vulnerability increases when other factors are also involved, such as poor breast and complementary feeding practices combined with high rates of infectious diseases (Solomons & Vossenaar, 2013; Ntila et al., 2017). There are pockets of information available on complementary feeding practices and its social determinants from specific areas in South Africa, regarding infant and young child feeding practices beyond six months of age and requires further investigation (Issaka et al., 2015; Seonandan & McKerrow, 2016). Aim: To explore the association between mothers’ socio-cultural environment and the dietary diversity of their children between the ages of 6 and 24 months, who attend the health care clinic in Olievenhoutbosch Township, Gauteng. Methodology: A quantitative cross-sectional explorative study was implemented. Data collection was conducted at Olievenhoutbosch clinic in Gauteng during February and March 2019. Mothers of children aged between 6 and 24 months were included and interviewed. Consecutive sampling was applied. The data collection instruments were a set of structured questions to obtain socio-demographic, nutritional knowledge, maternal attitude and feeding practices data. The infant and young child minimum dietary diversity (IYCMDD) questionnaire adapted from the WHO questionnaire was used to determine the DD of each child. Ethical clearance was obtained from the Ethics Committee of the College of Agriculture and Environmental Sciences (CAES) at the University of South Africa. Descriptive and inferential statistics was applied using SPSS version 25 (SPSS Inc, Chicago, IL, USA). Results: The sample of mothers (n=103) were educated (75% completed matric and 18% completed post-school education), unemployed (73%) and mostly single (53%) which are all factors playing a role in child nutrition. The majority (58%) of children were between the ages of 6 and 11 months while 42% were between the ages of 12 and 24 months. The milk feeding practices differed significantly between the younger and older groups of children with 35% of the younger children receiving breastmilk (in addition to complementary foods), compared to 21% of the older group. Almost half (44%) of the total group reported that maize meal porridge was the first food introduced to their children. Less than half of the mothers (45%) initiated the first foods at the recommended age of 6 months but started as early as one month of age (13%). All children (100%) consumed foods from the “grains, roots and tubers” food group the previous day. Significantly less children from the younger age group were reported to have consumed dairy (38% vs 77%, p<0.001) (other than breast or formula milk), animal flesh foods (31% vs 59%, p=0.014) and legumes (8% vs 24%, p=0.034), compared to the older age group. Significantly more children from the older group met the minimum dietary diversity (MDD) of four food groups compared to the younger group (67% vs 38%, p=0.019). No association was found between most socio-cultural factors (maternal age, marital status, education and employment status) and DD. However, there was an association between maternal ethnicity and DD (𝑥2=16.62, p=0.002). Also, maternal nutrition knowledge and the child’s DD had a significant, positive linear relationship (p=0.026). Lastly, maternal attitude towards feeling confident in not overfeeding the child were associated with meeting the MDD. Conclusion: The diets of young children residing in Olievenhoutbosch, do not meet the criteria for a minimally acceptable diet with only 50% meeting the MDD. Legumes and animal source foods are not consumed in sufficient quantities for complementary feeding. Maternal ethnicity and nutritional knowledge were associated with the child’s DD. More emphasis should be placed on DD for young children. / Vhubvo: Maitele o teaho a thikhedzo ya kuṋetshedzele kwa zwiḽiwa kha vhana vhaṱuku a nga khwaṱhisedza vhuimo ha gumofulu ha pfush na u fhungudza phimo ya dzimpfu dza vhana vha fhasi ha miṅwaha ya fhasi ha 5 (Jones na vhaṅwe, 2014).

Ghana subscribed to the global target of reaching at least 50% of exclusive breastfeeding in the first six months of birth by the year 2030. Policies and programmes to promote exclusive breastfeeding have been formulated and implemented in the country. In spite of these efforts, existing evidence showed that the rate of exclusive breastfeeding in the first six months post-delivery has been declining over the past decade. It was therefore important to understand behavioural factors that influence exclusive breastfeeding among teenage-mothers and propose a behavioural conceptual model based on the understanding of exclusive breastfeeding from the perspective of the teenage-mothers and their social environments. The study was conducted in three phases using multistrand mixed methods within the pragmatism philosophical framework. The Theory of Planned Behaviour and the six steps framework for developing models to address public health issues were used as frameworks in the study. In the first phase, the researcher used qualitative exploratory descriptive design to gain an understanding of the behavioural determinants of exclusive breastfeeding from the perspective of teenagers aged between 13 - 19 years attending antenatal care services at public facilities. Data were generated through focus group discussions and analysed using Group-level thematic and content analysis. In the second phase, longitudinal descriptive correlational designs were used to establish the relationships between the exclusive breastfeeding intentions during the prenatal period and actual breastfeeding practices at six months post-delivery. Structured questionnaires were used to collect data during the last visit of antenatal care visits and six months post-delivery. Data generated were analysed through descriptive inferential statistics. In the last phase, the researcher used meta-inferences to identify the key concepts of conceptual model from the integrated qualitative and quantitative results. Theoretical triangulations were used to define and establish relationships between the concepts and to structure the conceptual model. The integrated results of the two phases of the study showed that exclusive breastfeeding practices among teenage-mothers within the social context of Ghana are determined by certain personal and social related behavioural factors. The approval of the exclusive breastfeeding practice by the teenagers’ mothers and nurses/midwives’ capabilities to provide effective breastfeeding education were the strongest determinants of exclusive breastfeeding up to six months among teenage-mothers in Ghana. From these results, the researcher proposed an integrated behavioural conceptual model that provides an understanding of exclusive breastfeeding practice and the process of promoting exclusive breastfeeding among teenage-mothers in the social context of Ghana. The findings of this study have implications for public health policy-makers, health services managers, health sciences education and further research. / Health Studies / D. Lit. et Phil.

The objectives of this study were to determine the nature of data recorded on the Road to Health Card (RtHC) and its utilisation by nurses at primary health care setting, comparing it with norms and standards on the RtHC guideline, and to provide guidelines for optimal utilisation of the RtHC by health workers. A quantitative nonexperimental descriptive method was used. Two methods were used to collect data; document analysis of the RtHC and structure observation of nurses. A structured exit interview of caregivers was conducted to validate observations from nurses. A sample size of 18 nurses from all categories from six clinics was observed, and 36 RtHC of children under five years of age were analysed. Results indicated that data recorded on the RtHC was mostly inaccurate, incomplete and not interpreted. The study identified a need to train health workers on optimal utilisation of the RtHC facilitating health improvement of children under five years of age. / Health Studies / M.A. (Health Studies)

This cross-sectional exploratory and descriptive quantitative study explored the factors that impact on feeding practices of infants 0-12 months, encountered in the Child Welfare Clinic in Tema Manhean Health Centre and to determine the possible factors that lead to malnutrition. The population for this study comprised all infants who attended the Child Welfare Clinic at the Tema Manhean Health Centre. Three hundred and ninety infants participated in this study. Data was collected by means of a structured questionnaire and analysed using the Statistical Package for the Social Sciences (SPSS) Version 20. Findings of the study revealed that a larger number of the mothers were still breastfeeding at the time of data collection. All infants aged six months or older were given complementary foods. Some of the factors found to be associated with infant malnutrition included education of mother, employment status of mother, marital status, cultural practices and parity. / Health Studies / M.A.(Public Health)

Vertical transmission of HIV is still a growing concern in South Africa. Breastfed infants are still at risk as HIV is present in breast milk, leaving HIV-positive mothers unsure of the best feeding option for their infants. However, there are various infant feeding techniques that HIV-positive mothers can use to supplement breastfeeding and flash-heat is one of them. Flash-heat is heat treating expressed breast milk to deactivate HIV for infant feeding. This study explored the possibility of HIV-positive mothers to practice flash-heating method for their infants exclusively for four months as a strategy to prevent vertical transmission of HIV. A descriptive, explorative and contextual design using a mixed method was used to obtain data from mothers in a post natal ward at Tembisa hospital. The mixed method used was useful in identifying the number of HIV-positive mothers who would adopt the flash-heat technique, the characteristics of mothers whom the technique could be promoted to, the factors that influence/affect the choice of infant feeding for these mothers, as well as their feelings associated with the feeding technique. Most (74%) mothers had a positive response to the flash-heat technique compared to 10% who were uncertain. They believed that heat treating their breast milk would result in their infants being HIV-free. In addition they believed that this method was cheaper than formula feeding and expressed positive feelings about touching their breast milk while expressing with no adverse feelings of expressing into a glass jar. Furthermore, findings of this study indicated that HIV-positive mothers in a public health facility would adopt flash-heat as an alternative infant feeding method. Thus practical guidelines to promote this feeding method were proposed. The proposed draft guidelines which promote the use of the flash-heat infant feeding method for HIV-positive mothers in public sector facilities will be communicated to relevant authorities such as the National Department of Health. These guidelines support the new policy shift to exclusive breastfeeding as a child survival strategy in South Africa. / Health Studies / D.Litt. et Phil. (Health Studies)
