ABSTRACT
Background: Work-related low back pain (LBP) has received growing attention, especially regarding the effect it has on work productivity and activities of daily living (ADL). Supermarket cashiers are at high risk of LBP due to maintaining awkward postures for prolonged periods. Objectives: To investigate the prevalence and intensity of LBP among supermarket cashiers in KwaZulu-Natal, South Africa, and to identify occupational and non-occupational risk factors for LBP. Methods: Supermarket cashiers from 12 conveniently selected stores of a major South African supermarket franchise were included in this cross-sectional study. Questionnaires were administered in October and November 2018. Mean LBP disability scores were used as a measure of pain intensity experienced during various activities. Univariate analysis of variance (ANOVA) was used to measure the effect size of different variables on the LBP intensity score. The associations between LBP and both occupational and non-occupational factors were assessed using Fischer's exact test and forward stepwise logistic regression analysis. Results: One hundred and forty-six cashiers participated in the study. Most of the participants reported having minimal LBP (n = 132, 90.4%), indicating that they could cope with most living activities. Based on the mean disability scores, only the effect size of age was large. The odds of having LBP were associated with age 30 years and older (p = 0.001), race other than black African (p = 0.037), and working for more than 10 hours a day (p = 0.039). Conclusion: Reporting of LBP was common among the supermarket cashiers in this study. Older workers are at a higher risk of having LBP, which may be exacerbated by long working hours. Workplace interventions such as ergonomic programmes, structured and defined working hours, and home-based interventions such as exercise therapy, should be implemented.

Low Back PainABSTRACT
Background. Maternal mental health during the perinatal period has been of interest to many researchers, with antenatal depression and postnatal depression (PND) being a leading cause of morbidity. The adverse effects of maternal depression on the offspring throughout infancy, childhood and adolescence are well documented. Studies on the mental health of persons living with HIV have also reported a high prevalence of depression. Objectives. To describe the prevalence of PND in a sample of HIV-positive and HIV-negative mothers delivering healthy singleton infants at one obstetric unit in KwaZulu-Natal (KZN) Province, South Africa, and the subsequent factors influencing neonatal behaviour and perceptions of caregiver competence. Correlations between the presence of PND and perceptions of caregiver competence (with the mother as caregiver), and between infant behaviour, the mother's confidence in her competence as caregiver, and demographic and medical variables, were also examined. Methods. Demographic and clinical data were collected from 132 mothers at initial contact and from 32 mothers at the 6-week follow-up appointment. Mothers independently completed the Edinburgh Postnatal Depression Scale at each time point, and the Mother and Baby Scales (MABS) at the 6-week follow-up appointment. Results. The prevalence of depression among all mothers at initial contact was 72.0%, remaining high (68.8%) among the mothers who returned for follow-up. There was a statistically significant correlation between depression and employment at follow-up (p=0.013), and between depression and delivery method (p=0.030). The majority of mothers reported being 'able to laugh and see the funny side of things' and 'looking forward with enjoyment to things' at initial contact and follow-up. Thoughts of self-harm were reported by 44.7% of mothers at baseline, and by 53.1% at follow-up. Although most infants scored in the average clinical band for neonatal behavioural factors in the MABS, mothers reported lack of confidence, globally and in caring for their infant. Conclusion. This study of maternal mental health of a sample of HIV-positive and HIV-negative mothers of infants in KZN revealed a higher prevalence of PND than reported in other studies. This population of mothers and infants is at risk of adverse outcomes of maternal depression, in addition to other possible risk factors.

Background. The use of social media for professional practice is an emerging trend for healthcare professionals; however, limited literature exists on the phenomenon. Social media usage is prevalent among students, as it is incorporated into many health professions education curricula. This poses potential ethical dilemmas.Objective. To examine the nature of social media usage and knowledge of ethical considerations by occupational therapy (OT) students for professional purposes.Methods. A quantitative, cross-sectional survey was administered to the entire cohort of OT students (N=128) enrolled at the University of KwaZulu- Natal, Durban, South Africa in 2016. Data were analysed descriptively using Microsoft Excel 2013 (Microsoft, USA).Results. The most commonly used device to access social media was mobile phones, with WhatsApp and YouTube frequently used for both general and professional purposes. Uses included accessing social media for developing professional skills and knowledge, and in fulfilling academic requirements. Ethical dilemmas were evident among students, who indicated that social media ethical considerations should be incorporated into the curriculum.Conclusion. The study highlighted that most students use some form of social media as part of their professional practice, which has the potential to be used effectively to enhance learning opportunities. Future studies of a qualitative nature could shed light on students' perceptions of social media and practical implications for practice
