Consumer objective and subjective knowledge about healthy foods: An approach to promote healthy lifestyle choices in South Africa.

Unhealthy food choices and consumption, coupled with sedentary lifestyles among consumers, intensify public health concerns regarding the quadruple disease burden, despite Primary Health Care (PHC) policy. However, the current relationship between consumer knowledge about healthy foods and following a healthy lifestyle needs to be explored. Our study, therefore, aimed to determine the association between consumers' subjective and objective knowledge about healthy foods and various healthy lifestyle choices. A cross-sectional survey was conducted among employed consumers (N = 157) from South African corporate settings. We used structural equation modelling (SEM) to determine associations between subjective and objective knowledge about healthy foods and healthy lifestyle choices. Our findings showed that most participants scored high on making healthy lifestyle choices relating to avoiding smoking (69.5%) and limiting drinking alcohol (68.7%) but less so for food and sleep (44.4%) while neglecting exercise, relaxation (13.7%), and choices that require dedicated effort (25.2%). On average, participants had high levels of subjective (mean = 3.59; 5-point Likert scale) knowledge and objective knowledge about healthy foods (88.4-95.9% correct responses). However, their objective knowledge about weight and cholesterol had severe deficiencies (36.7%). SEM confirmed an association between subjective knowledge and most healthy lifestyle choice categories, while income contributed to dedicated effort lifestyle choices. By contrast, objective knowledge did not associate with such choices. Our structural model suggests that subjective knowledge about healthy foods contributes to healthy lifestyle choices. Therefore, subjective knowledge and the objective knowledge deficiencies we identified among corporate consumers can serve as a valuable starting point for informed education to promote PHC policy and healthy lifestyle choices.

Strategies of Modelling Incident Outcomes Using Cox Regression to Estimate the Population Attributable Risk.

When the Cox model is applied, some recommendations about the choice of the time metric and the model's structure are often disregarded along with the proportionality of risk assumption. Moreover, most of the published studies fail to frame the real impact of a risk factor in the target population. Our aim was to show how modelling strategies affected Cox model assumptions. Furthermore, we showed how the Cox modelling strategies affected the population attributable risk (PAR). Our work is based on data collected in the North-West Province, one of the two PURE study centres in South Africa. The Cox model was used to estimate the hazard ratio (HR) of mortality for all causes in relation to smoking, alcohol use, physical inactivity, and hypertension. Firstly, we used a Cox model with time to event as the underlying time variable. Secondly, we used a Cox model with age to event as the underlying time variable. Finally, the second model was implemented with age classes and sex as strata variables. Mutually adjusted models were also investigated. A statistical test to the multiplicative interaction term the exposures and the log transformed time to event metric was used to assess the proportionality of risk assumption. The model's fitting was investigated by means of the Akaike Information Criteria (AIC). Models with age as the underlying time variable with age and sex as strata variables had enhanced validity of the risk proportionality assumption and better fitting. The PAR for a specific modifiable risk factor can be defined more accurately in mutually adjusted models allowing better public health decisions. This is not necessarily true when correlated modifiable risk factors are considered.

Sedentariness and overweight in relation to mortality in sub-Saharan Africa. A mediation analysis based on the World Health Organization-Global Health Observatory data repository.

Background: Globally, noncommunicable diseases (NCDs) have been continuously reported to be the number one leading cause of reduced life expectancy and poor life quality and have thus become a major public health concern. Objective: This study aimed to investigate the complex mediation analysis between physical inactivity and overweight in relation to mortality. Methods: The study is based on public data collected by the Global Health Observatory of the World Health Organization. Results: We showed that the median early mortality attributable to NCDs during the period 2016-2019 in both men and women was 23.2% (5th to 95th range=17.2, 35.6) while that in men alone was 25.1% (16.5, 45.7) and that of women alone was 22.0% (17.0, 27.9). When considering regional early NCDs mortality for both men and women, a systematically high median was observed in Southern Africa [28.7% (22.2, 43.8)] and a low median in Eastern Africa [21.1% (17.15, 27.3)]. The analysis of the overall relation between physical inactivity, overweight and early mortality due to NCDs revealed a statistical significance of the direct association between physical inactivity and early mortality due to NCDs. Conclusion: Our findings revealed three main epidemiological and public health concerns. First, early mortality attributable to NCDs in a range of about 20 to 30% across the sub-Saharan African regions for both sexes was observed. Second, there was a direct effect between physical inactivity and early NCDs mortality as well as the indirect effect mediated by overweight. Finally, a percentage point decrease in physical inactivity prevalence and overweight could effectively generate a reduction in mortality due to NCDs. Future studies are needed to confirm the scientific evidence observed in this study. Such studies should be based on observation of individual subjects, adopt a longitudinal design, and collect information that evaluates the complex relationship between physical inactivity and early NCDs mortality, along with the role of overweight as a possible mediator.

Self-Reported Level of Cultural Competence of Midwives in the North-West Province of South Africa.

INTRODUCTION: Limited research on cultural competence in nursing, midwifery, and education exists within low- and middle-income countries such as South Africa (SA). This study aimed to describe midwives' self-reported levels of cultural competence toward women receiving maternal care. METHODOLOGY: A descriptive, cross-sectional survey design and an all-inclusive sample of (N = 104; n = 82) midwives yielded a 79% response rate. Data were collected using the Transcultural Self-Efficacy Tool (TSET) questionnaire. Participants included midwives recruited from maternity units of five hospitals in South Africa: different hospitals that included one large district, two regional, and two tertiary hospitals in the North-West Province of SA. An all-inclusive sample of (N = 104; n = 82) midwives participated, representing a 79% response rate. RESULTS: Midwives reported an overall moderate level of competence regarding their knowledge and understanding of cultural factors; it was concerning that their confidence in interviewing patients from different cultural backgrounds on factors such as acculturation and worldview were the lowest. DISCUSSION: To the best of the authors' knowledge, this was the first study to assess the cultural competence of midwives in SA using TSET. The study highlighted the need for midwives' training to improve their cultural competence.

Facilitators and barriers to implementing antimicrobial stewardship programs in public South African hospitals.

Objective: The South African National Department of Health released guidelines and recommendations for antimicrobial stewardship (AMS) programs to be established in public healthcare facilities. Their implementation remains challenged, especially in North West Province, where the public health system functions under severe strain. This research explored and interpreted the facilitators that strengthen and barriers that hinder the implementation of the national AMS program in public hospitals in North West Province. Design: A qualitative design and interpretive descriptive approach enabled insight into the realities of AMS program implementation. Setting: Public hospitals in North West Province, sampled through criterion sampling (n = 5). Participants: Purposive criterion sampling of healthcare practitioners (n = 30) actively participating in AMS programs in the 5 sampled public hospitals. Method: Qualitative, interpretive description with semi-structured individual interviews that were digitally recorded and transcribed. The ATLAS.ti version 8 software facilitated content analysis, followed by second-level analysis. Results: In total, 4 themes, 13 categories, and 25 subcategories emerged. We detected dissonance between government AMS ideals and the realities of AMS program implementation in public hospitals. A multilevel AMS leadership and governance vacuum exists in a dysfunctional health ecosystem in which AMS must operate. Healthcare practitioners agreed on the importance of AMS despite different understandings of AMS and ineffective multidisciplinary teams. Discipline-specific education and training are essential for all AMS participants. Conclusions: AMS is essential yet complex, and its contextualization and implementation are underestimated in public hospitals. Recommendations are focused on a supportive organizational culture, contextualized AMS program implementation plans, and changes in management.

Health Promotion Workforce in South Africa: Direction from the Australian Health Promotion Association.

BACKGROUND: South Africa's progress towards forming a health promotion workforce lags behind the health promotion career opportunities and professional standards guided by the Australian Health Promotion Association (AHPA), from which South Africa can learn valuable lessons. PROBLEM STATEMENT: Despite the existence of a national health promotion strategy, inconsistencies in health promotion workforce standards are a national reality. In one of the 10 National Health Insurance pilot districts in South Africa, researchers investigated health care workers' experiences of the barriers and enablers for the health promotion workforce. METHODOLOGY: A qualitative explorative descriptive design was used. Health care workers (health promoters, n = 8; operational managers, n = 6; senior managers, n = 3) in Dr Kenneth Kaunda District's public health sector were sampled using purposive proportional quota sampling. Data were gathered through semi-structured individual interviews until data saturation was reached (N = 17). Transcribed interviews were thematically analysed, supported by ATLAS.ti 8. RESULTS: Five themes and thirteen sub-themes emerged, and barriers to the health promotion workforce exceeded enablers. Health promotion workforce structure and policies were deficient. Managerial supervision and monitoring were lacking. The health promotion workforce received insufficient resources with limited implementation of health promotion programs. Formal and informal health promotion training was necessary. RECOMMENDATIONS: The AHPA's proposed Health Promotion Workforce model is considered, focusing on a clear workforce structure, strengthened by managerial buy-in and efficient monitoring and evaluation. Formal and informal health promotion training and advocacy of the health promotion workforce industry are highlighted. Countries with emerging economies and similar health systems to South Africa might find this article useful.

Sedentariness and overweight in relation to mortality in Sub-Saharan Africa. A Mediation analysis based on the WHO-Global Health Observatory Data Repository

Aims: The aim of the study was to investigate the complex mediation analysis between physical inactivity and overweight in relation to mortality. Methods: The study is based on public data collected by the Global Health Observatory (GHO) of the World Health Organisation. Results: We showed that the median early mortality attributable to NCDs during the period 2016 - 2019 in both men and women all together was 23.2% (5th to 95th range = 17.2, 35.6) while that in men alone was 25.1% (16.5, 45.7) and that of women was 22.0% (17.0, 27.9). When considering regional early NCDs mortality for both men and women, a systematically high median was observed in Southern Africa (28.7% (22.2, 43.8)) and a low median in Eastern Africa (21.1% (17.15, 27.3)). The analysis of the overall relation between physical inactivity, overweight and early mortality due to NCDs revealed a statistical significance of the direct association between physical inactivity and early mortality due to NCDs. Conclusion: Our findings revealed three main epidemiological and public health concerns. First, an early mortality attributable to NCDs in a range of about 20% to 30% across the SSA regions for both sexes were observed. Second, there was a direct effect between physical inactivity and early NCDs mortality as well as for the indirect effect mediated by overweight. Finally, a percentage point decrease of physical inactivity prevalence and overweight could effectively generate a reduction of mortality due to NCDs. Future studies are needed to confirm the scientific evidence observed in this study. Such studies should be based on observation of individual subjects, adopt a longitudinal design, and collect information that evaluate the complex relation between physical inactivity and early NCDs mortality, along with the role of overweight as a possible mediator.

Prognostic values of modifiable risk factors for cardiovascular events in South African health promotion.

BACKGROUND: Cardiovascular diseases (CVDs) are increasing at an alarming rate among the South African population. This study aimed to determine the prognostic value of modifiable CVD risk factors for fatal and non-fatal events to inform cardiovascular health promotion practices in the South African public health system. METHODS: Data was collected from individuals participating in the South African leg of a multi-national prospective cohort study. Binary logistic regression was applied to estimate odds of total, non-fatal and fatal cardiovascular events. RESULTS: Binary logistic regression analyses identified age as a predictor of non-fatal and fatal CV events, with ORs of 1.87 to 3.21, respectively. Hypertension increased the odd of suffering a non-fatal CV event by almost two and a half (OR = 2.47; 95% CI = 1.26, 4.85). Moreover, being physically active reduced the odd of non-fatal CVD events by 38% (OR = 0.62; 95% CI = 0.46, 0.83 for 1 Standard deviation increase of the weighted physical activity index score (WPA)). On the one hand, gamma-glutamyltransferase (GGT) was associated with a higher fatal cardiovascular disease risk OR = 2.45 (95% CI = 1.36, 4.42) for a standard deviation increase. CONCLUSIONS: Elevated blood pressure, GGT, and physical activity have significant prognostic values for fatal or non-fatal CV events. These findings emphasise the importance of highlighting hypertension and physical activity when planning cardiovascular health education and intervention programmes for this population, with attention to the monitoring of GGT.

When online learning becomes compulsory: Student nurses' adoption of information communication technology in a private nursing education institution.

BACKGROUND: Integrating the use of information communication technology (ICT) in nursing curricula when preparing student nurses for the digital health future such as the sudden online learning as a result of the coronavirus disease 2019 (COVID-19) pandemic is vital. However, when student nurses in a South African private nursing education institution, struggled to complete obligatory online learning courses, nurse educators had to search for solutions. OBJECTIVES: To explore the barriers and enablers for ICT adoption by a diverse group of student nurses in a private nursing education institution in the Free State Province. METHOD: Following a qualitative, explorative, interpretive-descriptive design, student nurses were invited to participate. Based on all-inclusive, purposive sampling with inclusion criteria enabled selecting, a total of 17 participants who took part in three focus groups and written narratives. Transcribed interviews underwent thematic analysis with co-coder consensus. The study adhered to strategies to enhance trustworthiness. RESULTS: Students shared their views related to ICT and online learning within their theory and practice training. Student nurses held positive, negative and contrasting views of ICT adoption and online learning. Actions to master ICT adoption and online learning are highlighted. Information communication technology brings a challenging interdependence between nurses and technology. CONCLUSION: Integration of ICT into nursing programmes is important. The enablers and barriers to ICT are described. Expose students to different technologies, especially using smart phones to search for (academic/non-academic) information. The adoption of ICT should enhance the learning process and facilitate deep learning. Students preferred online learning for self-assessment and described how they tried to master ICT and online learning. Information communication technologies in the clinical setting highlight the challenged interdependence between nurses and technology. Context-specific recommendations are proposed.

Predictors of parents' infant vaccination decisions: A concept derivation.

The myths surrounding coronavirus disease 2019 (COVID-19) vaccines have prompted scientists to refocus their attention on vaccine hesitancy, which is fuelled by the spread of misinformation. The scientific investigation of behavioural concepts relating to vaccine hesitancy can be enhanced by the examination of behavioural concepts from the field of consumer sciences. South African consumer scientists study personal decisions that contribute to individuals' well-being, including the decisions to prevent ill health. Current data on the predictors of vaccination decisions do not incorporate consumer science constructs imperative in decision-making, which could provide fresh insights in addressing vaccine hesitancy. This study aimed to investigate and illustrate the analogy between concepts of the Health Belief Model (HBM) as parent model, and consumer behaviour that could affect parents' infant vaccination decisions, by applying a concept derivation approach. The HBM was analysed within the context of public health, including literature from consumers' vaccination decisions, medical decisions, paediatrics, vaccinology, virology and nursing. Through a qualitative, theory derivation strategy, six main concepts of the HBM were redefined to consumer sciences, using four iterative concept derivation steps. Concept derivation resulted in consumer behaviour concepts that could be possible predictors of parents' infant vaccination decisions, including consumers' values; risk perception; consideration of immediate and future consequences; self-efficacy; cues to action; demographics; personal information and knowledge. These predictors could be a starting point for a context- and product-specific consumer primary preventive healthcare decisions model. Our findings highlight the opportunities for interdisciplinary collaboration in investigating consumer primary healthcare-related behaviour. CONTRIBUTION: This study introduced interfaces between consumer science and health science literature. Through interdisciplinary collaboration, a better understanding of influences to promote primary preventive healthcare can be achieved.

Coverage and factors associated with vitamin A supplementation among children aged 6-59 months in twenty-three sub-Saharan African countries.

OBJECTIVE: The present study aimed to give an overall view of the pattern of high-dose vitamin A supplementation (VAS) coverage in twenty-three sub-Saharan African countries and factors associated with receipt of VAS among children aged 6-59 months. DESIGN: Cross-sectional data from the twenty-three Demographic and Health Surveys conducted from 2011 to 2015 in twenty-three sub-Saharan African countries were pooled. A multilevel logistic regression model was used to explore factors associated with VAS. SETTING: Twenty-three sub-Saharan African countries.ParticipantsChildren (n 215 511) aged 6-59 months. RESULTS: The overall coverage of VAS among children aged 6-59 months for the surveys included was 59·4 %. In the multivariable analysis, children whose mothers had primary (adjusted OR (aOR)=1·43; 95 % CI 1·39, 1·47) or secondary or above (aOR=1·72; 95 % CI 1·67, 1·77) educational status were more likely to receive VAS than children whose mothers had no formal education. Other factors associated with significantly increased likelihood of VAS were: living in urban areas; children of working mothers; children whose mothers had higher media exposure; children of older mothers v. children of mothers aged 15-19 years; and older children v. children aged 6-11 months. At the country level, lower media exposure was significant and negatively associated with VAS. CONCLUSIONS: Broader VAS coverage is needed according to our data. More efforts are needed to scale up coverage, focusing mostly on groups at risk of non-receipt of vitamin A.

Conflict pressure cooker: Nurse managers' conflict management experiences in a diverse South African workplace.

BACKGROUND: Nurse managers are central to conflict management and a healthy work environment. South Africa is one of the most diverse countries globally and workplace diversity is a reality in healthcare organisations. There is a gap in academic literature on conflict management by nurse managers in diverse workplaces in South Africa. AIM: This research aims to understand nurse managers' experiences of conflict management within a diverse South African workplace (military hospital) in order to facilitate a healthy work environment. SETTING: The context was a diverse, medical military organisation servicing all nine South African provinces. This military hospital employed staff of varying nationalities, catering to military and private patients, and functioned within a strict hierarchical structure. METHODS: Purposive sampling was used. Thirteen unstructured, individual interviews were conducted based on a qualitative, phenomenological design. The interviews were followed by content analysis and five main themes emerged as a result. RESULTS: A hierarchical, diverse organisational culture complicates conflict management. The ranking structure, resource shortages, intergenerational dynamics, poor communication and distrust cause conflict. Nurse managers experience conflict daily and are central to conflict management. As such, they have certain personal characteristics and display specific conflict management skills. Conflict management skills can be taught, but this requires an intra- to interpersonal process. A major challenge for the nursing profession today is the younger nurses who seem less passionate and nurse managers who are under more pressure than before. CONCLUSION: A medical military organisation presents an organisational culture that combined with diversity is predisposed to conflict, which endangers the work environment. Yet, both conflict and workplace diversity can, when managed correctly, enrich a healthcare organisation. Nurses and nurse managers will benefit from reflective conflict management training as an intra- to interpersonal process.

Prediction of cadmium concentration in selected home-produced vegetables.

Soil contaminated with cadmium presents a potential hazard for humans, animals and plants. The latter play a major role in the transfer of cadmium to the food chain. The uptake of cadmium and its accumulation by plants is dependent on various soil, plants and environmental factors. In order to identify soil properties with statistically significant influence on cadmium concentration in vegetables and to reduce the collection of data, time and costs, regression models can be applied. The main objective of this research was to develop regression models to predict the concentration of cadmium in 9-vegetable species: zucchini, tomato, cabbage, onion, potato, carrot, red beet, endive and chicory, based on soil properties. Soil samples were collected from 123 home gardens of the Municipality of Celje and 59 of these gardens were also included in vegetable sampling. The concentration of elements (e.g. arsenic, cadmium, copper, lead, and zinc) in the samples was determined by Inductively Coupled Plasma Mass Spectrometry. Single (for cabbage, potato, red beet and chicory) and multiple (for tomato, onion, carrot and endive) linear regression models were developed. There was no statistically significant regression model for zucchini. The most significant parameter for the influencing the cadmium concentration in vegetables was the concentration of cadmium in soil. Other important soil properties were the content of organic matter, pH-value and the concentration of manganese. It was concluded that consuming carrots, red beets, endives, onions, potatoes and chicory which are grown in gardens with Cd concentrations (mgkg(-1) DW) above 2.4, 3.2, 6.3, 7.9, 8.3 and 10.9, respectively, might represent an important contribution to dietary Cd exposure.

Exploring home visits in a faith community as a service-learning opportunity.

BACKGROUND: Within South Africa the Psychiatric Nursing Science curriculum in undergraduate Baccalaureate nursing education utilizes home visits as a service-learning opportunity. In this context faith communities are currently unexplored with regards to service-learning opportunities. With limited literature available on this topic, the question was raised as to what are these students' and family members' experience of home visits within a faith community. PURPOSE: To explore and describe nursing students' and family members' experiences of home visits within a faith community. DESIGN: A qualitative approach was used that was phenomenological, explorative and descriptive and contextual in nature. SETTING: The research was conducted within a faith community as service learning opportunity for Baccalaureate degree nursing students. This community was situated in a semi-urban area in the North-West Province, South Africa. PARTICIPANTS: Eighteen (n=18) final year nursing students from different cultural representations, grouped into seven groups conducted home visits at seven (n=7) families. METHODS: Comprehensive reflective reporting after the visits, namely that the students participated in a World Café data collection technique and interviews were conducted with family members. RESULTS: Three main themes emerged: students' initial experiences of feeling overwhelmed but later felt more competent; students' awareness of religious and cultural factors; and students' perception of their role. Two main themes from the family members emerged: experiencing caring and growth. CONCLUSIONS: There is mutual benefit for nursing students and family members. Students' experiences progress during home visits from feeling overwhelmed and incompetent towards a trusting relationship. Home visits in a faith community seems to be a valuable service learning opportunity, and the emotional competence, as well as spiritual and cultural awareness of nursing students should be facilitated in preparation for such home visits.

Practice environment, job satisfaction and burnout of critical care nurses in South Africa.

AIM: To describe the practice environment, job satisfaction and burnout of critical-care nurses (CCNs) in South Africa (SA) and the relationship between these variables. BACKGROUND: CCNs are more sensitive to job satisfaction and burnout, and several studies have been published on the relationship between these variables. However, the research that was undertaken did not focus exclusively on the practice environment of CCNs or the context of SA. METHOD: The RN4CAST survey was used. A stratified sample of 55 private hospitals and seven national referral hospitals were included in the study. A total of 935 CCNs completed the survey. RESULTS: The practice environment is positive, except for staffing and resource adequacy, and governance. The greatest job dissatisfaction is experienced with regard to wages, opportunities for advancement and study leave. CCNs have a high degree of burnout. CONCLUSION: The high degree of burnout is related to dissatisfaction with wages, opportunities for advancement, study leave and a practice environment with inadequate staffing and resources, and lack of nurse participation in hospital affairs. IMPLICATIONS FOR NURSING MANAGEMENT: Managers should ensure that adequate numbers of CCNs are on the staff allocation and provide opportunities for CCNS to participate in policy and governance of the hospital, while giving attention to good salaries and providing opportunities for advancement and study leave.
