A scoping review to identify the type and effect of hand hygiene interventions on the reduction of infectious diseases (including COVID-19) in preschool children

Background. Proper handwashing can reduce the burden of diseases related to hand hygiene (HH) and so contribute reducing under-5 mortality. Preschoolers can benefit from HH interventions by the burden of disease and absenteeism being reduced. Objective. To perform a scoping review of literature to assess the types and effectiveness of HH interventions at preschools, with a view to providing a guideline for appropriate interventions for South African facilities. Methods. A literature search was conducted through the PubMed database to identify relevant studies. An iterative screening process to focus the review allowed for information on the type and effectiveness of interventions to be collated. An updated PubMed search was conducted to determine whether any interventions related to COVID-19 at preschools could be included. Results. No additional studies relating to COVID-19 were found. Of the 305 studies identified during the initial search, only 12 fitted the specific search criteria. Of these, 10 studies showed improvements in HH-related indicators following the interventions. Only two studies used health education as an intervention, whereas the others included the supply of HH products (to varying extents) as part of the intervention. Conclusion. HH interventions appear successful in reducing diseases spread by poor HH, improving general HH practices and reducing absenteeism among preschoolers. Studies using innovative, entertaining methods of educating children have shown to be successful in improving handwashing techniques and decreasing microbial growth on children's hands. HH interventions are suggested as an effective measure to improve HH during the COVID-19 pandemic.

Prevalence of tobacco use in selected Johannesburg suburbs

Background. Tobacco smoking is estimated to kill more than 44 000 South Africans every year. Studies have shown that since the introduction of tobacco control measures, national smoking prevalence has declined in South Africa (SA). Objective. To determine the prevalence of tobacco smoking over a 7-year period in five impoverished neighbourhoods in Johannesburg, SA.Methods. Data were collected through the annual administration of a prestructured questionnaire to one adult respondent in preselected dwellings from 2006 to 2012. Information was collected on socioeconomic status, smoking practices and health status.Results. Over the 7-year period of the analysis, smoking levels remained unchanged. The proportion of households with one or more smokers varied significantly across the five study neighbourhoods. Approximately 20% of households in Hillbrow and as many as 77% in Riverlea had a member who smoked.Conclusions. Despite a national downward trend in smoking levels, tobacco use remains high and persistent in certain vulnerable communities, requiring scaled-up action to reduce the risk of a range of tobacco-related diseases

The Prevalence and Health Implications of Violence in Impoverished Communities in Johannesburg

The experience of violent crime can have a significant impact on the physical and psychological well-being of victims and their families. This paper looks at household experience of violence in five impoverished sites in the city of Johannesburg; South Africa. Five sites were purposefully selected to reflect the prevailing housing profiles in settings of relative impoverishment in Johannesburg. A structured questionnaire was used to obtain information on demographic profiles; socioeconomic data; environmental conditions and health status. Bivariate analyses were conducted to assess the relationship between household experience of violence; and potential risk factors and health/social outcomes. Overall; members of 28of households had been a victim of violence in the year preceding the study. Across sites; experience of violence within households ranged from 21to 36. Perceptions of drug abuse (p=0.01) and drug peddling (p=0.03) as being major problems in the neighbourhood; and living in a house of poor quality (p=0.01); were significantly associated with household experience of crime. In households with experience of violence; fear of crime (p=0.03) and depression (p 0.001) were elevated; and levels of exercise in men were decreased (p
