A survey of perceptions and behavioural responses towards the COVID-19 pandemic in South Africa
Full text linkBackground: The South African response to the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus was swift and assertive, although it came with economic and social costs. An understanding of the pandemic experiences of different population groups is integral to enhancing disease control.
Aim: The aim of this study was to identify behavioural responses and public perceptions relating to the coronavirus disease 2019 (COVID-19) pandemic.
Setting: The study was conducted in South Africa.
Methods: In June 2022, a national online survey (N = 3018) was conducted among adults ( 18 years). Logistic regression was used to examine the factors associated with adherence to government measures and vaccination. Structural equation modelling (SEM) was applied to examine the direct and indirect relationship of socioeconomic status (SES) with protective behaviours.
Results: Data showed no direct association between SES and vaccination uptake, but SES was indirectly and positively associated with vaccination uptake. Socioeconomic status was also indirectly and positively associated with adherence to government measures through pathways mediated by access to the Internet, access to local news, government trust and positive government experiences.
Conclusion: This study highlights the complexity of government measures and vaccination adoption and the socioeconomic barriers affecting these.
Contribution: Results from this study should be used to inform future pandemic preparedness plans. In particular, policymakers should consider the importance of providing scientific information through channels accessible to each socioeconomic group to promote positive behavioural changes, as well as the need to adapt pandemic responses to different socioeconomic groups
Alignment between chronic disease policy and practice : case study at a primary care facility
No full textIncludes bibliographical references.Current literature supports the need to make the prevention and management of chronic diseases an international health priority. In South Africa, our Health Minister has committed the government to tackling the burden of chronic diseases alongside communicable diseases. The Western Cape has developed an excellent policy and framework to guide and improve the prevention and management of chronic diseases at a primary care level, however limited literature exists around the alignment of the policy with current practice and around any challenges to its implementation. Should the policy be well implemented, it has the potential to make a significant difference to the health of the population served. For this reason, the overall purpose of this study is to improve the care and management of patients with chronic diseases within primary health care facilities. The aim of this study is to assess the alignment of current primary care practices with the PGWC Adult Chronic Disease Management policy (which includes an audit tool), using one primary health care facility in the Cape Town metropolis as a case study
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Cost-effectiveness of a complex continuum of care intervention targeting women and children: protocol for an economic evaluation of the Bukhali trial in South Africa
No full textIntroduction As nearly two-thirds of women presenting at their first antenatal visit are either overweight or obese in urban South Africa, the preconception period is an opportunity to optimise health and offset transgenerational risk of both obesity and non-communicable diseases. This protocol describes the planned economic evaluation of an individually randomised controlled trial of a complex continuum of care intervention targeting women and children in Soweto, South Africa (Bukhali trial).Methods and analysis The economic evaluation of the Bukhali trial will be conducted as a within-trial analysis from both provider and societal perspectives. Incremental costs and health outcomes of the continuum of care intervention will be compared with standard care. The economic impact on implementing agencies (programme costs), healthcare providers, participants and their households will be estimated. Incremental cost-effectiveness ratios (ICERs) will be calculated in terms of cost per case of child adiposity at age years averted. Additionally, ICERs will also be reported in terms of cost per quality-adjusted life year gained. If Bukhali demonstrates effectiveness, we will employ a decision analytical model to examine the cost-effectiveness of the intervention over a child’s lifetime. A Markov model will be used to estimate long-term health benefits, healthcare costs and cost-effectiveness. Probabilistic sensitivity analyses will be conducted to explore uncertainty and ensure robust results. An analysis will be conducted to assess the equity impact of the intervention, by comparing intervention impact within quintiles of socioeconomic status.Ethics and dissemination The Bukhali trial economic evaluation has ethical approval from the Human Ethics Research Committee of the University of the Witwatersrand, Johannesburg, South Africa (M240162). The results of the economic evaluation will be disseminated in a peer-reviewed journal and presented at a relevant international conference
Contextualising individual, household and community level factors associated with sugar-sweetened beverage intake and screen time in Soweto, South Africa
No full textThis study examined the relationship between individual, household, and community-level factors with obesity-related health behaviors. Households (n = 6110) were enumerated, and participants (>18 years) reported their screen time and how many sugar-sweetened beverages they consumed per day. Individuals from food insecure and higher SES households were more likely to report higher sugar-sweetened beverage consumption. Screen time was negatively associated with age (p < .01), and being female was associated with 35 minutes more screen time per day (p < .01). Community and household factors were independent drivers of behavior that need to be incorporated into individual level interventions, or considered in analyses.</p
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Exploring early childhood development interventions for building human capital in sub-Saharan Africa: a scoping review
No full textBackground: Inequalities in the provision and implementation of early childhood development (ECD) interventions in Sub-Saharan Africa remain a challenge. This scoping review aimed to investigate the types and extent of ECD interventions in this region, using the Nurturing Care framework (NCF).Methods: This review included randomised controlled trial (RCT) studies related to ECD interventions in Sub-Saharan Africa. Sources from 2019 to 2024 were included. PubMed, MEDLINE (Ebsco), Web of Science, ProQuest and PsychInfo were searched in September 2024. Abstracts and full texts were reviewed using Rayyan.Results: Of 85 studies retrieved, 21 conducted across 13 countries were included in our review. Most were conducted in Eastern and Southern Africa, with Western and Central Africa notably underrepresented. Sample sizes varied from 134 to over 9000 participants. ECD interventions targeting children from 0 to 8 years old were included. Nutrition-focused interventions were the most common (n = 9) and showed the biggest positive impact on child weight and growth. Responsive caring interventions were the second most common (n = 2), resulting in fewer reports of maltreatment, reduced endorsement of corporal punishment and fewer behavioural problems in children. The remaining three NCF dimensions (i.e., early learning opportunities, safety and security, and good health) each had only one intervention focusing solely on that dimension and showed mixed results on child development. Multidimensional interventions were common, with seven studies combining multiple ECD support elements to create a holistic approach. Although these interventions showed mixed results, they were more likely to report positive outcomes across multiple NCF domains compared to single-focus interventions.Conclusions: Most interventions focus only on a couple of NCF elements. There is a need for increased focus on underrepresented regions to address local ECD needs effectively and to develop and evaluate interventions that incorporate all elements of NCF in African contexts
Development, implementation, and process evaluation of Bukhali: an intervention from preconception to early childhood
No full textThe Healthy Life Trajectories Initiative, an international consortium developed in partnership with the World Health Organization, is addressing childhood obesity from a life-course perspective. It hypothesises that an integrated complex intervention from preconception, through pregnancy, infancy and early childhood, will reduce childhood adiposity and non-communicable disease risk, and improve child development. As part of the Healthy Life Trajectories Initiative in South Africa, the Bukhali randomised controlled trial is being conducted with 18–28-year-old women in Soweto, where young women face numerous challenges to their physical and mental health. The aims of this paper were to describe the intervention development process (including adaptations), intervention components, and process evaluation; and to highlight key lessons learned. Intervention materials have been developed according to the life-course stages: preconception (Bukhali), pregnancy (Bukhali Baby), infancy (Bukhali Nana; birth—2 years), and early childhood (Bukhali Mntwana, 2–5 years). The intervention is delivered by community health workers, and includes the provision of health literacy resources, multi-micronutrient supplementation, in-person health screening, services and referral, nutrition risk support, SMS-reminders and telephonic contacts to assist with behaviour change goals. A key adaption is the incorporation of principles of trauma-information care, given the mental health challenges faced by participants. The Bukhali process evaluation is focussing on context, implementation and mechanisms of impact, using a mixed methods approach. Although the completion of the trial is still a number of years away, the documentation of the intervention development process and process evaluation of the trial can provide lessons for the development, implementation, and evaluation of such complex life-course trials
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
