Applying Social Practice Theory to Explore Australian Preschool Children's Oral Health

INTRODUCTION

Despite substantial research and provision of dental care, significant morbidity remains for children's oral health. Guided by social practice theory (SPT), this research moves away from the often-ineffective focus on changing individual behavior to rethinking the centrality of the social world in promoting or undermining oral health outcomes. We define social practice as a routinized relational activity linking and integrating certain elements (competence, materials, and meanings) into the performance of a practice that is reproduced across time and space.

OBJECTIVE

To investigate oral health in preschool children in Perth, Western Australia, using social practice theory.

METHODS

With no definitive methodology for investigating SPT, we chose focused ethnography as a problem-focused, context-specific approach using mainly interviews to investigate participants' experience caring for their children's oral health. The focus of analysis was the practice of oral health care, not individual behavior, where themes identified from participants' transcripts were organized into categories of elements and performance.

RESULTS

Eleven parents, all of whom were married or partnered, were interviewed in 2021. Findings identified social practices relevant to oral health within parenting and family relations linked to routine daily activities, including shopping, consumption of food and beverages, and toothbrushing. Oral health literacy was reflected in integrating competence, materials, and meanings into performing oral health care, notably preferences for children to drink water over sugary beverages and information often being sourced from social media and mothers' groups rather than health providers.

CONCLUSION

Focusing on social practices as the unit of analysis offers a more layered understanding of elements in young children's oral health care that can indicate where the problem may lie. Findings provide an opportunity to consider future research and policy directions in children's oral health.

KNOWLEDGE TRANSFER STATEMENT

Examining social practices related to young children's oral health care identifies parents/carers' knowledge about, for example, toothbrushing, the resources required, and why toothbrushing is important. Analyzing these separate elements can reveal both enablers and barriers to oral health care. This provides researchers, clinicians and policymakers an opportunity to focus on not changing individual behavior but understanding how social context impacts parents/carers' capacity to make optimum decisions around young children's oral health.

Next-generation sequencing as a screening tool for foodborne pathogens in fresh produce

Next generation sequencing (NGS) approaches are increasingly applied to tracing microbial contaminants entering the food chain due to NGS' untargeted nature and ability to investigate non-culturable (and/or difficult to culture) organisms while yielding genomic information about the microbiota. So far, a plethora of microbes has been shown to be associated with fresh produce, but few studies have utilised NGS to identify contamination with human pathogens. This study aims to establish the limit of detection (LoD) for Salmonella and phage MS2 (a Norovirus surrogate) contamination of fresh produce employing NGS approaches on the Illumina MiSeq: 16S amplicon-sequencing, and RNA-seq, using ScriptSeq (Illumina) and NEBNext (New England BioLabs) kits. ScriptSeq proved the most sensitive approach; delivering an LoD of 10⁴ CFU reaction^-1 (Colony Forming Units) for Salmonella and 10⁵ PFU reaction^-1 (Plaque Forming Units) for phage MS2. Use of the NEBNext kit resulted in detection of Salmonella at 10⁶ CFU reaction^-1 and phage MS2 at 10⁷ PFU reaction^-1. 16S amplicon-sequencing yielded a similar LoD of 10⁵ CFU reaction^-1 for Salmonella but could not detect MS2. The tested NGS methodologies, in combination with bioinformatics approaches applied, proved less sensitive than conventional microbial detection approaches.

Virtual worlds and avatars as the new frontier of telehealth care

We are entering a new age where people routinely visit, inhabit, play in and learn within virtual worlds (VWs). One in eight people worldwide are VW participants, according to the latest 2011 figures from KZERO [1]. VWs are also emerging as a new and advanced form of telehealth care delivery. In addition to existing telehealth care advantages; VWs feature three powerful affordances that can benefit a wide range of physical and psychological issues. First, the highly social nature of VWs encourages social networking and the formation of essential support groups. Secondly, the type of spaces that have been proven in the physical world to promote psychological health and well-being can be virtually recreated. Finally, research suggests that embodied avatar representation within VWs can affect users psychologically and physically. These three aspects of VWs can be leveraged for enhanced patient-client interactions, spaces that promote healing and positive responses, and avatar activities that transfer real benefits from the virtual to the physical world. This paper explains the mounting evidence behind these claims and provides examples of VWs as an innovative and compelling form of telehealth care destined to become commonplace in the future.

A low-cost approach to public health education using multimedia packages

The effect of health education programmes depends on the number of people exposed to the messages, as well as the method and style in which the information is transmitted. We conducted a pilot project to encourage healthier lifestyles by presenting culturally sensitive information using a variety of media. Material intended to provoke discussion was shared with a range of audiences in Barbados and Montserrat in the West Indies by a series of lecture discussions, which were videorecorded for local television and sound recorded for local radio. The lecture was also disseminated by newspaper articles, a special magazine and by publication on the Internet. The aim of the project was to achieve maximum effect for minimum effort, thus making optimum use of resources. The feedback obtained at the lecture discussions and in response to the radio broadcasts and newspaper articles provided a needs assessment on which to base a definitive programme, and confirmed that radio and television are the most effective media for health education.

Low-cost video-films in the teaching of undergraduate and postgraduate medical students

The high cost of producing good-quality video-films for teaching has hindered the use of this method, which has been shown to improve significantly the efficiency of teaching and the retention of knowledge. During the last five years, a series of short video-films has been produced using inexpensive video-cameras and home video-recording and editing equipment. A variety of techniques were developed to allow recording of lecture presentations, while using the equipment as a teaching aid, without the need for technical staff. The positioning of the camera, the monitor, the slide projector and lighting were critical to the productions. Similar productions at low cost were obtained from recordings of operating theatre sessions, tutorials and clinical ward rounds. A survey of students exposed to teaching with video-film as part of a lecture presentation confirmed that the subject matter being taught was more easily understood and enjoyable and generated more discussions on than other forms of teaching.

The ward milieu and its effect on the behaviour of psychogeriatric patients

Research relating environment and behaviour indicates that relatively minor changes in the environment, such as restructuring a dayroom, can result in significantly improved psychosocial functioning in psychogeriatric patients. A project introducing multiple changes designed to improve the quality of life on a geriatric ward in a provincial mental hospital is described and discussed in the light of that research and suggestions are made regarding its replication under more rigorous experimental conditions.
