ABSTRACT

BACKGROUND: The COVID-19 outbreak is in an accelerating phase, and South Africa (SA) has had the highest number of documented cases during the early phase of the pandemic in sub-Saharan Africa. OBJECTIVES: To assess South Africans' understanding of and response to COVID-19 during the first week of the country's lockdown period. METHODS: An online survey was conducted in SA from 27 March to 2 April 2020. The survey was distributed widely among several websites and social media networks, including on a data-free platform. Descriptive statistics of knowledge, risk perception, access to and trust in information sources, and public and media opinions were calculated. Estimates were benchmarked to the 2019 national adult population estimates. RESULTS: Of the 55 823 participants, the majority (83.4%) correctly identified the main symptoms of COVID-19. Over 90% had correct knowledge of the incubation period, with lower rates for 18 - 29-year-olds. Knowledge of symptoms and the incubation period varied significantly by population group (p<0.001), dwelling type (p<0.001) and sex (p<0.001). A quarter (24.9%) perceived themselves as at high risk of contracting COVID-19. Risk perception varied by age, population group, employment status and dwelling type (p<0.001). The most prevalent COVID-19 information sources were government sources (72.9%), news websites/apps (56.3%), satellite television (51.6%) and local television (51.4%). CONCLUSIONS: Understanding knowledge, attitudes and behaviours of people facing the COVID-19 pandemic is crucial for guiding strategic policy. These findings provide public understanding of COVID-19 as the phases of the country-level epidemic progress, and also directly inform communication needs and gaps.

ABSTRACT

BACKGROUND: Despite a variety of contraceptives being available for women in South Africa, a considerable number of adolescent girls and young women still face challenges in using them. This paper examines socio-demographic and behavioral predictors of using contraceptives among adolescent girls and young women (AGYW) aged 15 to 24 years. METHODS: A secondary data analysis was conducted based on the 2012 population-based nationally representative multi-stage stratified cluster randomised household survey. Multivariate backward stepwise logistic regression model was used to examine socio-demographic and behavioural factors independently associated with contraceptive use amongst AGYW aged 15 to 24 years in South Africa. RESULTS: Out of 1460 AGYW, 78% (CI: 73.9-81.7) reported using some form of contraceptives. In the model, contraceptive use was significantly associated with secondary education [OR = 1.8 (1.2-2.7), p = 0.005], having a sexual partner within 5 years of their age [OR = 1.8 (1.2-2.5), p = 0.002], and sexual debut at age 15 years and older [OR = 2.5 (1.3-4.6), p = 0.006]. The likelihood of association decreased with other race groups-White, Coloured, and Indians/Asians [OR = 0.5 (0.3-0.7), p = 0.001], being married [OR = 0.4 (0.2-0.7), p = 0.001], never given birth [OR = 0.7 (0.5-0.9), p = 0.045], coming from rural informal [OR = 0.5 (0.3-0.9), p = 0.010] and rural formal settlements [OR = 0.5 (0.3-0.9), p = 0.020]. CONCLUSIONS: Evidence suggest that interventions should be tailor-made to meet the needs of AGYW in order to, promote use and access to contraceptives. The results also suggest that family planning interventions should target those who had not given birth in order to reduce unplanned and or unintended pregnancies and associated risk factors. These findings contribute to public health discourse and reproductive health planning for these age groups in the country.

ABSTRACT

BACKGROUND: In South Africa, HIV is increasingly becoming a chronic disease as a result of advances in HIV treatment and prevention in the last three decades. This has changed the perception from a life threating to a potentially manageable disease. However, little is known about self-perceived health status of HIV-infected individuals. Self-rated health (SRH) has been shown to be a sensitive indicator of health-relatedchanges directly linked to HIV, but can also be influenced by differences in social and material conditions. The aim of this paper was to identify determinants of excellent/good SRH among HIV-infected individuals using socio-demographic, life style and health related data. METHODS: The study used data from the nationally representative 2012 South African population-based household survey on HIV prevalence, incidence and behaviour conducted using multi-stage stratified cluster sampling design. Bivariate and multivariate logistic regression models were used to identify determinants of SRH among HIV-infected individuals. RESULTS: Out of a total of 2632 HIV positive participants 74.1% (95% CI: 68.4-74.2) reported excellent/good SRH. Increased likelihood of reporting excellent/good SRH was significantly associated with being Black African [OR= 1.97 (95%CI: 1.12-3.46), p = 0.019] and belonging to least poor household [OR= 3.13 (95%CI: 1.26-7.78), p = 0.014]. Decreased likelihood of reporting excellent/good SRH was significantly associated with those aged 25 to 34 years [OR= 0.49 (95% CI: 0.31-0.78), p = 0.003], 35 to 44 years[OR= 0.27 (95% CI: 0.17-0.44), p < 0.001], 45 to 54 years [OR= 0.20 (95% CI: 0.12-0.34), p < 0.001], and those 55 years and older [OR= 0.15 (95% CI: 0.09-0.26), p < 0.001], hospitalization in the past twelve months [OR= 0.40 (95% CI: 0.26-0.60), p < 0.001]. CONCLUSION: To have positive health effects and improve the perceived health status for PLWH social interventions should seek to enhance to support for the elderly HIV-positive individuals, and address the challenge of socio-economic inequalities and underlying comorbid conditions resulting in hospitalization.

ABSTRACT

BACKGROUND: In South Africa, voluntary medical male circumcision (VMMC) has recently been implemented as a strategy for reducing the risk of heterosexual HIV acquisition among men. However, there is some concern that VMMC may lead to low risk perception and more risky sexual behavior. This study investigated HIV risk perception and risk behaviors among men who have undergone either VMMC or traditional male circumcision (TMC) compared to those that had not been circumcised. METHODS: Data collected from the 2012 South African national population-based household survey for males aged 15 years and older were analyzed using bivariate and multivariate multinomial logistic regression, and relative risk ratios (RRRs) with 95 % confidence interval (CI) were used to assess factors associated with each type of circumcision relative no circumcision. RESULTS: Of the 11,086 males that indicated that they were circumcised or not, 19.5 % (95 % CI: 17.9-21.4) were medically circumcised, 27.2 % (95 % CI: 24.7-29.8) were traditionally circumcised and 53.3 % (95 % CI: 50.9-55.6) were not circumcised. In the final multivariate models, relative to uncircumcised males, males who reported VMMC were significantly more likely to have had more than two sexual partners (RRR = 1.67, p = 0.009), and males who reported TMC were significantly less likely to be low risk alcohol users (RRR = 0.72, p < 0.001). CONCLUSION: There is a need to strengthen and improve the quality of the counselling component of VMMC with the focus on education about the real and present risk for HIV infection associated with multiple sexual partners and alcohol abuse following circumcision.

ABSTRACT

The goals of the Abstinence and Be Faithful Among Youth (ABY) project were to enhance local responses among the youth in South Africa to prevent HIV infection through encouraging abstinence; faithfulness and avoidance of unhealthy sexual behaviour among youths over a five-year period. A quantitative baseline evaluation of the ABY project was conducted in five cities in South Africa. Data were collected from learners and youths just before the ABY intervention started at nine randomly selected sites in Johannesburg; Cape Town; Durban; Port Elizabeth and Mthatha using a three-stage cluster sampling design. In total; nine sites were randomly selected from a possible eighteen. At each of the data-collection points; data were collected from 60 participants. In total there were 27 data-collection points and 1620 respondents. Young people have strong views on abstaining from sexual intercourse; as 83said that it was possible not to have sex for as long as you can. There was also strong support for abstinence; as 78.5said that not having sex was the best way of preventing infection with HIV. In total; 68.1of the youths said that the media had a positive influence on encouraging abstinence and 72.1said role models could help them not to have sex; while 84.3said that leadership and life skills workshops were helpful in encouraging them to abstain from sex. In total; 68.7of young people said that the media encouraged faithfulness in relationships and 84.6said that life skills workshops were helpful in encouraging them to remain faithful to one partner. Young people have strong views on and support for abstinence. They also have strong views on and perceptions of remaining faithful to one partner. These findings are a valuable guide to the views and perceptions of young people with respect to abstinence and faithfulness before interventions are implemented

ABSTRACT

In epidemiological studies where subjects are seen periodically on follow-up visits, interval-censored data occur naturally. The exact time the change of state (such as HIV seroconversion) occurs is not known exactly, only that it occurred sometime within a specific time interval. Methods of estimation for interval-censored data are readily available when data are independent. However, methods for correlated interval-censored data are not well developed. This paper considers an approach for estimating the parameters when data are interval-censored and correlated within sexual partnerships. We consider the exact event times for interval-censored observations as unobserved data, only known to be between two time points. Dependency induced by sexual partnerships is modelled as frailties assuming a gamma distribution for frailties and an exponential distribution on the time to infection. This formulation facilitates application of the expectation-maximization (EM) algorithm. Maximization process maximizes the standard survival frailty model. Results show high degree of heterogeneity between sexual partnerships. Intervention strategies aimed at combating the spread of HIV and other sexually transmitted infections (STI)s should treat sexual partnerships as social units and fully incorporate the effects of migration in their strategies.

ABSTRACT

In October 1998, cohorts of circular migrant men and their non-migrant sexual partners, and non-migrant men and their non-migrant sexual partners from rural South Africa were recruited and followed-up every 4 months until October 2001. At each visit, information on sociodemographic, sexual behaviour, sexually transmitted infections (STIs) and HIV was collected. In total, 553 individuals aged between 18 and 69 years were recruited. A man and his sexual partner(s) form a sexual partnership. Migration status, age, marital status, age at sexual debut, recent sexual partners and HIV status were found to be important determinants of STI. The risk of STI varies (sigma2 = 1.45, P < 0.001) significantly across sexual partnerships even after controlling for important determinants. The variance implies substantial correlation (0.59) between members of the same sexual partnership. Ignoring this correlation leads to incorrect inference. Migration contributes significantly to the spread of STIs. Community interventions of HIV/STI should target co-transmitter sexual partnerships rather than high-risk individuals.

ABSTRACT

OBJECTIVE: Available evidence on the relationship between marital status and HIV is contradictory. The objective of this study was to determine HIV prevalence among married people and to identify potential risk factors for HIV infection related to marital status in South Africa. METHODS: A multistage probability sample involving 6 090 male and female respondents, aged 15 years or older was selected. The sample was representative of the South African population by age, race, province and type of living area, e.g. urban formal, urban informal, etc. Oral fluid specimens were collected to determine HIV status. A detailed questionnaire eliciting information on socio-demographic, sex behaviour and biomedical factors was administered through face-to-face interviews from May to September 2002. RESULTS: HIV prevalence among married people was 10.5% compared with 15.7% among unmarried people (p-value < 0.001). The risk of HIV infection did not differ significantly between married and unmarried people (odds ratio (OR) = 0.85, 95% confidence interval (CI): 0.71 - 1.02) when age, sex, socio-economic status, race, type of locality, and diagnosis of a sexually transmitted infection (STI) were included in the logistical regression model. However, the risk of HIV infection remained significantly high among unmarried compared with married people when only sex behaviour factors were controlled for in the model (OR 0.55; 95% CI: 0.47 - 0.66). CONCLUSIONS: The relationship between marital status and HIV is complex. The risk depends on various demographic factors and sex behaviour practices. Increased prevention strategies that take socio-cultural context into account are needed for married people.

ABSTRACT

This study was a prospective audit of patients receiving either intravenous induction of anaesthesia with propofol 2 mg/kg or inhalational induction using 8% sevoflurane for patients undergoing electroconvulsive therapy (ECT). All patients received inhaled 50% nitrous oxide. The anaesthetic agent was determined by psychiatrist preference. Each psychiatrist nominated only one induction technique for all his or her patients. Seventy treatments were studied in each group. Induction time was longer in the sevoflurane group. The time from commencing induction to loss of verbal contact was [mean (SD)] 64 (29.9) seconds for sevoflurane and 36 (33.6) seconds for propofol (P=0.001). Time to loss of eyelash reflex was 82 (32.6)s for sevoflurane and 44 (17.9)s for propofol (P<0.001). The duration of seizure activity was longer in sevoflurane patients, 35 (17.8)s, compared with 20 (9.8)s in the propofol group (P< 0.001). Discharge times were similar Minor adverse effects occurred in three patients, all in the sevoflurane group (one bradycardia and two episodes of post-procedural nausea). There were no major adverse events in either group. Propofol and sevoflurane both appear to be suitable agents for induction of anaesthesia for ECT.

ABSTRACT

We investigate the prevalence of, and risk factors for, HIV infection among women in an urban South African setting. A random sample of 834 women was recruited into a community-based cross-sectional study. HIV prevalence was 37.1% with higher prevalence among migrant women (46.0%) than non-migrant women (34.7%), (odds ratio [OR]=1.61, 95% confidence interval [CI]: 1.11-2.31). The highest HIV prevalence (50.9%) was between ages 26 and 35 years. Having two or more lifetime partners increased the risk of HIV infection (OR=4.88, 95% CI: 3.01-7.89). Migration, age, marital status, alcohol use, syphilis and gonorrhoea were independently associated with HIV infection. Migration increases the risk of HIV infection. Provision of services to treat sexually transmitted diseases and educational empowerment programmes that will promote safer sex among migrant women are urgently needed.

ABSTRACT

BACKGROUND: Syphilis remains a significant cause of preventable perinatal death in developing countries, with many women remaining untested and thus untreated. Syphilis testing in the clinic (on-site testing) may be a useful strategy to overcome this. We studied the impact of on-site syphilis testing on treatment delays and rates, and perinatal mortality. METHODS: We conducted a cluster randomised controlled trial among seven pairs of primary healthcare clinics in rural South Africa, comparing on-site testing complemented by laboratory confirmation versus laboratory testing alone. Intervention clinics used the on-site test conducted by primary care nurses, with results and treatment available within an hour. Control clinics sent blood samples to the provincial laboratory, with results returned 2 weeks later. RESULTS: Of 7134 women seeking antenatal care with available test results, 793 (11.1%) tested positive for syphilis. Women at intervention clinics completed treatment 16 days sooner on average (95% confidence interval: 11 to 21), though there was no significant difference in the proportion receiving adequate treatment at intervention (64%) and control (69%) clinics. There was also no significant difference in the proportion experiencing perinatal loss (3.3% v 5.1%; adjusted risk difference: -0.9%; 95% CI -4.4 to 2.7). CONCLUSIONS: Despite reducing treatment delays, the addition of on-site syphilis testing to existing laboratory testing services did not lead to higher treatment rates or reduce perinatal mortality. However on-site testing for syphilis may remain an important option for improving antenatal care in settings where laboratory facilities are not available.

ABSTRACT

BACKGROUND: In South Africa, where health care resources are limited, it is important to ensure that drugs provision and use is rational. The Essential Drug List includes depot medroxyprogesterone acetate (DMPA) and norethisterone oenanthate (NET-EN) as injectable progestagen-only contraceptives (IPCs), and both products are extensively used. OBJECTIVES AND METHODS: Utilisation patterns of the injectable contraceptive products DMPA and NET-EN are compared in the context of current knowledge of the safety and efficacy of these agents. Utilisation patterns were analysed by means of a Pareto (ABC) analysis of IPCs issued from 4 South African provincial pharmaceutical depots over 3 financial years. A case study from rural KwaZulu-Natal, South Africa, is used to examine utilisation patterns and self-reported side effects experienced by 187 women using IPCs. RESULTS: IPCs accounted for a substantial share of total state expenditure on drugs. While more DMPA than NET-EN was issued, NET-EN distribution from 2 depots increased over the 3-year period. Since DMPA was cheaper, if all NET-EN clients in the 1999/2000 financial year (annualised) had used DMPA, the 4 depots could have saved 4.95 million South African Rands on product acquisition costs alone. The KZN case study showed slightly more NET-EN (54%) than DMPA (46%) use; no significant differences in self-reported side effects; and that younger women were more likely to use NET-EN than DMPA (p = 0.0001). CONCLUSIONS: Providing IPCs on the basis of age is not appropriate or cost effective. Rational use of these products should include consideration of the cost of prescribing one over another.

ABSTRACT

BACKGROUND: The lightwand may be useful as an alternative for tracheal intubation during a rapid-sequence induction of anesthesia in the presence of a full stomach. This study was undertaken to assess the effect of application of cricoid pressure on the success of lightwand intubation. METHODS: Sixty adult female patients presenting for abdominal hysterectomy were randomly allocated to lightwand intubation with and without cricoid pressure. The time to successful intubation and number of attempts were recorded. RESULTS: All 30 patients allocated to intubation without cricoid pressure were intubated successfully at the first attempt within a median time of 28 s (95% confidence interval, 18-77 s). Lightwand intubation with cricoid pressure was successful in 26 of 30 patients at the first attempt, but the median time to successful intubation was significantly longer at 48.5 s (95% confidence interval, 36-78 s; P = 0.001). Three patients required two attempts for successful intubation, and one could not be intubated with the lightwand while cricoid pressure was being applied. CONCLUSIONS: The lightwand cannot be recommended for the first attempt at intubation where cricoid pressure is being applied because the time to successful intubation is significantly prolonged, and the failure rate for the first attempt at lightwand intubation is 13%.

ABSTRACT

To determine knowledge of, attitudes toward, and use of emergency contraception (EC), interviews were held with 1068 clients of 89 public sector primary healthcare facilities in two urban and two rural areas of South Africa. Only 22.8% of the clients had heard of EC. Awareness was significantly lower in the most rural area and among older, less educated women. Knowledge of EC was superficial, with 47.1% unsure of the appropriate interval between unprotected intercourse and starting EC and 56.6% not knowing whether it was available at the clinic. Few (9.1%) of those who knew of EC had used it. After explaining EC, attitudes toward its use were found to be positive, with 90.3% indicating that they would use it if needed. Awareness was lower than in developed countries, but higher than in other developing countries. Findings indicate that if women know of EC, where to get it, and how soon to take it, they would use it if needed.

ABSTRACT

OBJECTIVE: To demonstrate the impact on perinatal mortality of inadequate treatment for maternal syphilis despite adequate screening. METHOD: In 12 clinics providing antenatal care in Hlabisa, South Africa 1783 pregnant women were screened for syphilis at their first antenatal visit between June and October 1998. Pregnancy outcome was determined among those with syphilis. RESULTS: A total of 158 women were diagnosed with syphilis: prevalence 9% (95% CI 8-10%). Mean gestation at first antenatal visit was 24 weeks. Thirty women (19%) received no treatment and 96 (61%) received all three recommended doses of penicillin. Among those receiving at least one dose, mean delay to the first dose was 20 days. Among those fully treated mean delay to treatment completion was 34 days. Pregnancy outcome was known for 142 women (90%) and there were 17 perinatal deaths among 15 women (11%). Eleven of 43 women (26%) who received one or fewer doses of penicillin experienced a perinatal death whilst only four of 99 women (4%) who received two or more doses of penicillin did so (P = 0.0001). Protection from perinatal death increased with the number of doses of penicillin: linear modelling suggests that one dose reduced the risk by 41%, two doses by 65% and three doses by 79%, compared with no doses. A dose-specific, categorical model confirmed reduction in risk by 79% for all three doses. CONCLUSION: Despite effective screening, many pregnant women with syphilis remain inadequately treated, resulting in avoidable perinatal mortality. Delays in starting and finishing treatment, as well as incomplete treatment occur. Near-patient syphilis testing in the antenatal clinic with early treatment could improve treatment of syphilis and reduce perinatal mortality, and a randomized trial to test this is underway.
