Unsafe sex, substance use and dangerous driving : predicting adolescents' risk-taking

Adolescence involves heightened experimentation in risk-taking behaviours that are potentially health damaging. To prevent the negative consequences of increased engagement in risk-taking behaviours, it is necessary to understand the factors that influence adolescents' participation. This study investigated the extent to which late adolescents' sex, risk judgments, self-efficacy for sexual behaviour and substance use, and sensation seeking predict likelihood to engage in risk-taking behaviour. Questionnaires were administered to 46 male and 43 female University of Canterbury students aged between 18 and 20 years. Results indicated that adolescent males have significantly lower perceptions of risk than females. However, there was a tendency for over-estimation of risk. There was the predicted negative relationship between risk perception and likelihood to engage in risk-taking behaviours. Stepwise regression analyses indicated that sensation seeking was the main predictor of risk-taking likelihood, accounting for 36.8% of the variance. The inclusion of risk perception explained an additional 4.7% of the variance. Lower self-efficacy was also significantly related to higher risk-taking likelihood. Implications for adolescent risk intervention and education programmes will be discussed

The impact of social media as a strategic approach to corporate communication when handling crises at a selected South African bank

This study investigates the impact of social media as a strategic approach to corporate communication when handling crises at Bank X in the Gauteng province of South Africa. The study had three over-arching objectives; to determine the challenges that are encountered when handling crises about communication at Bank X, to determine if the leadership has the willingness to change their approach when formulating the strategy; to determine if social media has an impact on strategy formulation of crisis communication at Bank X; and lastly to make recommendations to Bank X’s leadership on how to incorporate the social media component as a communication approach to effectively handle crises. This research followed a qualitative research approach through one-on-one Microsoft Teams in-depth interviews with 10 participants. The study, through the analysis of the primary data, secondary data, and literature reviews, underpins and supports that there is an opportunity for Bank X to incorporate social media as a strategic element to the crisis communication strategy. The organisation’s crisis communication strategy needs to incorporate social media from a strategic perspective for it to be ahead of the curve when a crisis emerges online. The implications for Bank X are a lesson in the evolution of technology in the communication space and how imperative it is for the bank to evolve

A systematic review of the effectiveness of reading comprehension interventions in the South African multilingual context

International comparative measures show that South Africa has extremely low standards in reading. A variety of programmes aimed at boosting reading have been developed, however, the effectiveness of these programmes is unclear. Prior reviews of effective reading instruction practices have focused almost exclusively on learners whose first language and language of instruction is English. This paper reviews evidence from 17 intervention studies which focused on the teaching of reading comprehension in the distinctive multilingual context of South Africa. Although in line with prior reviews, we found some evidence that reading strategy instruction including vocabulary development are features of successful interventions alongside effective teacher education and resourcing of reading. These findings remained inconclusive due to variability in the quality of research, considerable methodological variations of the studies and the limited number of studies. Research in this field requires a more rigorous scientific approach to improve the evidence base

The published version can be accessed at the following link on the publisher’s website: https://doi.org/10.1186/s12884-022-05092-1BACKGROUND: The Midlands has amongst the highest rates of neonatal and infant mortality in the UK. A public health parent education and empowerment programme, aimed at reducing key risks associated with this mortality was established and evaluated in the region. This was undertaken in an attempt to identify areas for optimal delivery of the public health messages around reducing risks for neonatal and infant mortality. METHOD: Qualitatively assessment, using the software package Dedoose®, was undertaken. This involved analysis of reflections by the programme trainers, after the delivery of their training sessions to parents, families and carers, between 01 January and 31 December 2021. These were intended to capture insights from the trainers on parent, family, carer and staff perspectives, perceptions/misperceptions around reducing risks for infant mortality. Potential areas for improvement in delivery of the programme were identified from this analysis. RESULTS: A total of 323 programmes, comprising 524 parents, family members and carers were offered the programme. Analysis of 167 reflections around these interactions and those of staff (n = 29) are reported. The programme was positively received across parents, families, carers and staff. Four overall themes were identified: (a) reach and inclusion, (b) knowledge, (c) practical and emotional support and (d) challenges for delivery of the programme. Recommendations for improved delivery of the programme were identified, based on qualitative analysis. CONCLUSION: This novel approach to empowerment and education around neonatal public health messaging is a valuable tool for parents, families, carers and staff in the Midlands. Key practical recommendations for enhancing delivery of these critical public health messages were identified from this qualitative research. These are likely to be of value in other parts of the UK and globally.This project was funded through the Dudley Council and Dudley Public Health Nurture and Resilience Steering Group.Published onlin

Prevalence of sexually transmitted infections among young people in South Africa: A nested survey in a health and demographic surveillance site.

BACKGROUND: Sexually transmitted infections (STIs) and bacterial vaginosis (BV) are associated with increased transmission of HIV, and poor reproductive and sexual health. The burden of STIs/BV among young people is unknown in many high HIV prevalence settings. We conducted an acceptability, feasibility, and prevalence study of home-based sampling for STIs/BV among young men and women aged 15-24 years old in a health and demographic surveillance site (HDSS) in rural KwaZulu-Natal, South Africa. METHODS AND FINDINGS: A total of 1,342 young people, stratified by age (15-19 and 20-24 years) and sex were selected from the HDSS sampling frame; 1,171/1,342 (87%) individuals had ≥1 attempted home visit between 4 October 2016 and 31 January 2017, of whom 790 (67%) were successfully contacted. Among the 645 who were contacted and eligible, 447 (69%) enrolled. Consenting/assenting participants were interviewed, and blood, self-collected urine (men), and vaginal swabs (women) were tested for herpes simplex virus type 2 (HSV-2), chlamydia, gonorrhoea, syphilis, trichomoniasis, and BV. Both men and women reported that sample collection was easy. Participants disagreed that sampling was painful; more than half of the participants disagreed that they felt anxious or embarrassed. The weighted prevalence of STIs/BV among men and women, respectively, was 5.3% and 11.2% for chlamydia, 1.5% and 1.8% for gonorrhoea, 0% and 0.4% for active syphilis, 0.6% and 4.6% for trichomoniasis, 16.8% and 28.7% for HSV-2, and 42.1% for BV (women only). Of the women with ≥1 curable STI, 75% reported no symptoms. Factors associated with STIs/BV included having older age, being female, and not being in school or working. Among those who participated in the 2016 HIV serosurvey, the prevalence of HIV was 5.6% among men and 19% among women. Feasibility was impacted by the short study duration and the difficulty finding men at home. CONCLUSIONS: A high prevalence of STIs/BV was found in this rural setting with high HIV prevalence in South Africa. Most STIs and HIV infections were asymptomatic and would not have been identified or treated under national syndromic management guidelines. A nested STI/BV survey within a HDSS proved acceptable and feasible. This is a proof of concept for population-based STI surveillance in low- and middle-income countries that could be utilised in the evaluation of STI/HIV prevention and control programmes

Sarcoma and the 100,000 Genomes Project: our experience and changes to practice

The largest whole genome sequencing (WGS) endeavour involving cancer and rare diseases was initiated in the UK in 2015 and ran for 5 years. Despite its rarity, sarcoma ranked third overall among the number of patients' samples sent for sequencing. Herein, we recount the lessons learned by a specialist sarcoma centre that recruited close to 1000 patients to the project, so that we and others may learn from our experience. WGS data was generated from 597 patients, but samples from the remaining approximately 400 patients were not sequenced. This was largely accounted for by unsuitability due to extensive necrosis, secondary to neoadjuvant radiotherapy or chemotherapy, or being placed in formalin. The number of informative genomes produced was reduced further by a PCR amplification step. We showed that this loss of genomic data could be mitigated by sequencing whole genomes from needle core biopsies. Storage of resection specimens at 4 °C for up to 96 h overcame the challenge of freezing tissue out of hours including weekends. Removing access to formalin increased compliance to these storage arrangements. With over 70 different sarcoma subtypes described, WGS was a useful tool for refining diagnoses and identifying novel alterations. Genomes from 350 of the cohort of 597 patients were analysed in this study. Overall, diagnoses were modified for 3% of patients following review of the WGS findings. Continued refinement of the variant-calling bioinformatic pipelines is required as not all alterations were identified when validated against histology and standard of care diagnostic tests. Further research is necessary to evaluate the impact of germline mutations in patients with sarcoma, and sarcomas with evidence of hypermutation. Despite 50% of the WGS exhibiting domain 1 alterations, the number of patients with sarcoma who were eligible for clinical trials remains small, highlighting the need to revaluate clinical trial design

Predictors of COVID-19 Vaccine Hesitancy in South African Local Communities: The VaxScenes Study

South Africa launched a mass COVID-19 vaccination campaign in May 2021, targeting 40 million adults. Understanding predictors of COVID-19 vaccine intentions was required to achieve this goal. We conducted a population-based survey in June–July 2021 using the WHO Behavioral and Social Drivers (BeSD) of COVID-19 Vaccination tool to determine predictors of vaccine hesitancy, defined as intention to refuse or uncertainty whether to accept COVID-19 vaccination. There were 1193 participants, mean age 39 (standard deviation 15) years, and 53% women, of whom 58% trusted information provided by healthcare workers and 32% were vaccine hesitant. Independent predictors of vaccine hesitancy included concerns about side effects (odds ratio (OR) 11.41; 95% confidence interval (CI) 3.5–50.80), lack of access to the online vaccine registration platform (OR 4.75; CI 2.15–10.37), distrust of government (OR 3.0; CI 1.33–6.77), belief in conspiracy theories (OR 3.01; CI 1.32–6.77), having no monthly income (OR 1.84; CI 1.12–3.07), and depending on someone else to make vaccination decision (OR 2.47; CI 1.06–5.77). We identified modifiable predictors of vaccine hesitancy at the start of South Africa’s COVID-19 vaccination rollout. These factors should be addressed by different stakeholders involved in the national immunization program through tailored communication and other effective strategies that increase vaccine literacy, reach low-income households, and engender confidence in government

Emerging trends in non-communicable disease mortality in South Africa, 1997 - 2010

Objectives. National trends in age-standardised death rates (ASDRs) for non-communicable diseases (NCDs) in South Africa (SA) were identified between 1997 and 2010.Methods. As part of the second National Burden of Disease Study, vital registration data were used after validity checks, proportional redistribution of missing age, sex and population group, demographic adjustments for registration incompleteness, and identification of misclassified AIDS deaths. Garbage codes were redistributed proportionally to specified codes by age, sex and population group. ASDRs were calculated using mid-year population estimates and the World Health Organization world standard.Results. Of 594 071 deaths in 2010, 38.9% were due to NCDs (42.6% females). ASDRs were 287/100 000 for cardiovascular diseases (CVDs), 114/100 000 for cancers (malignant neoplasms), 58/100 000 for chronic respiratory conditions and 52/100 000 for diabetes mellitus. An overall annual decrease of 0.4% was observed resulting from declines in stroke, ischaemic heart disease, oesophageal and lung cancer, asthma and chronic respiratory disease, while increases were observed for diabetes, renal disease, endocrine and nutritional disorders, and breast and prostate cancers. Stroke was the leading NCD cause of death, accounting for 17.5% of total NCD deaths. Compared with those for whites, NCD mortality rates for other population groups were higher at 1.3 for black Africans, 1.4 for Indians and 1.4 for coloureds, but varied by condition.Conclusions. NCDs contribute to premature mortality in SA, threatening socioeconomic development. While NCD mortality rates have decreased slightly, it is necessary to strengthen prevention and healthcare provision and monitor emerging trends in cause-specific mortality to inform these strategies if the target of 2% annual decline is to be achieved
