Item An exploration of the adoption of personal nonpharmaceutical intervention measures by students at a university of technology in response to the COVID-19 pandemic(2024) Kell, Colette Melissa; Haffejee, Firoza; Jinabhai, Champaklal C.Background In March 2020 the World Health Organisation (WHO) declared coronavirus disease (COVID-19) to be a global pandemic. Due to the novel nature of the virus, there was no effective vaccine or established treatment methods, and public health officials turned to the personal non-pharmaceutical protective intervention (NPI) measures of physical distancing, hand sanitisation and the wearing of masks to interrupt disease transmission and ‘flatten’ the pandemic curve. Despite the WHO recommendation that NPIs should be included as part of any pandemic response, prior to the COVID-19 pandemic, little behavioural science research had been conducted on how to improve NPI adoption. During the COVID-19 pandemic, many Knowledge, Attitude and Practice (KAP) surveys investigated NPI compliance, but there is a dearth of qualitative literature to provide insight into the barriers and facilitators to adoption in specific populations. Over the past two decades, the South African Higher education sector has largely been transformed to accommodate students from poor and rural backgrounds. As a result, students requiring accommodation in the urban centres where universities are often based, has dramatically increased. During the COVID-19 pandemic these students effectively became mobile members of their households, returning home at various times and lockdown levels, potentially spreading the disease to relatively isolated areas. In addition, studies have consistently found that young people were more likely to be considered non adopters of the COVID-19 NPIs, partly due to the increase in risk taking behaviour associated with adolescence. In South Africa, the risk behaviour of young people is also of significant public health concern in the context of HIV/AIDS, teenage pregnancy, substance abuse and violence, this is compounded by the limited success of large research interventions. Yet, despite the acknowledgement of the need for specificity in designing youth targeted interventions, there has been little exploration of how and why South African adolescents adopt positive behaviours. Knowledge of which would be useful to better understand behaviour motivation and inform strategies for positive behaviour change. Aim This study aimed to gain an understanding of the factors influencing the adoption of the personal NPIs in response to the COVID-19 pandemic, among students at a University of Technology (UOT). Insight into these factors was used to develop guidelines to inform the design of targeted interventions to promote positive behaviour change by South African adolescents. Methodology This exploratory, qualitative study sought to understand behaviour change using the Capability, Opportunity, Motivation, Behaviour (COM-B) model. Eighteen student participants at a UOT were selected using purposive, maximum variability sampling. Each participant was interviewed individually via Microsoft Teams. Data was transcribed verbatim and analysed both deductively and inductively. Deductive analysis was guided by Theoretical Domains Framework which was developed to integrate with the COM-B model. Where possible, participant statements were coded to the appropriate domain, statements relevant to the aim of the study but did not align with the TDF domains which were inductively analysed using the Tesch approach to qualitative analysis and Braun and Clarke (2006) thematic approach. Findings This study found that NPI adoption among students evolved over time, closely aligned to the available published literature regarding NPI efficacy and WHO recommendations, but not necessarily aligned to or in compliance with government regulations. A notable exception was the reduced compliance when interacting with loved ones. In these circumstances, despite high levels of both the psychological and physical capability to perform the protective behaviours, the participants lacked the social opportunity and emotional motivation to do so. Notable factors that facilitated NPI adoption included trust in international health organisations, personal experience of COVID-19 and an altruistic desire to protect others. Factors that acted as barriers to NPI adoption included in-group trust, government distrust and social disapproval for adoption. The major themes that emerged included the need for autonomy in adolescent health decision making, the importance of social connection, the influence of social media, and the need to include young people in the development of targeted behaviour change interventions (BCIs). Conclusion This study contributes to the limited body of knowledge regarding the factors that served as barriers and facilitators to the adoption of positive health behaviours by South African adolescents in the context of the COVID-19 pandemic. These factors contributed to the development of guidelines which can be utilised by the relevant stakeholders when designing BCIs targeting this group.Item The role of psychosocial risk factors on the prevalence of low back pain amongst Grade 12 learners in public schools in the greater Durban area(2010) Seethal, Verusha J.; Van Niekerk, L.; Wilson, Laura MaieBackground: Low back pain (LBP) is the most prevalent musculoskeletal condition experienced by human beings and the most common cause of disability in developed nations. Psychosocial factors, involving aspects of social and psychological behaviour, have previously been documented as potential risk factors in the development of adult LBP. However, more research is required to fully understand the role of psychosocial risk factors on the prevalence of LBP amongst adolescents. Objective: To determine the prevalence of LBP and to identify selected psychosocial risk factors associated with LBP amongst Grade 12 learners in the Greater Durban area. Methods: A population-based study was conducted amongst a stratified random sample of 20 public secondary schools in all three educational districts in the Greater Durban area. Data was collected by means of a structured questionnaire administered to the sample population consisting of Grade 12 learners. Using an exploratory research design, the individuals reported on demographics as well as prevalence, severity, frequency and chronicity of LBP. In addition, data was obtained regarding various psychosocial risk factors including depression, exam stress and anxiety, socio-economic status, family history of LBP, smoking, alcohol and drug abuse amongst the respondents. Results: The prevalence of LBP was 57.42% with a median frequency of 8 times a month. About a third (33.9%) of the respondents experienced difficulty bending whilst 35% reported that their LBP spread down to the legs below their knees. The daily activity most affected by LBP was having a good night‟s sleep (50.6%), followed closely by playing sports (47.4%) and concentrating in class (46.6%). The majority of the respondents that suffered from LBP had taken pain relief medication (47.1%) whilst only 21% of the respondents had missed school because of LBP. With regards to the psychosocial risk factors under investigation, three of the risk factors did not show any association to LBP. They included socio-economic status, smoking and recreational drug use. In contrast, five psychosocial risk factors showed an 6 association to LBP. They included alcohol abuse, family history, exam stress, anxiety and depression. Finally, after adjusting for all other risk factors for adolescent LBP, depression and high exam stress showed the strongest correlation with the occurrence of LBP amongst Grade 12 learners in the Greater Durban area. Conclusion: LBP amongst adolescents is a common problem that increases with age, representing a risk for LBP in adulthood. The researcher is of the opinion, that this illustrates the need for further investigations with more profound studies on the risk factors so that more light can be shed on how to manage this ever-growing problem.
