[New technology of diabetes management: learning together and in situation]. / Nouvelle technologie de gestion du diabète: apprendre ensemble et en situation.

The introduction of a new technology for the management of diabetes raises questions about their actual use. This is the case with the Freestyle Libre sensor, a tool that measures the interstitial glucose levels. Some studies have provided recommendations about its use, but little is known about how users learn to use it in the daily management of the disease. This ethnographic research explores this issue in the context of a summer camp for young people living with diabetes. The results describe three different levels (material, epistemic and moral) at which learning occurs. They show that its use requires an active appropriation process, the importance of a setting that promotes interactions between the participants and that the features of the tend to reconfigure the expert-lay person relationship.

L'introduction d'une nouvelle technologie de gestion du diabète soulève des questions sur son usage effectif. C'est le cas du capteur FreeStyle Libre, un outil mesurant la glycémie interstitielle. Des études ont fourni des recommandations sur son usage, mais on en sait peu sur la manière dont les usager-ère-s apprennent à l'utiliser dans la gestion quotidienne du diabète. Cette recherche ethnographique étudie cette question dans le cadre d'un camp d'été pour jeunes vivant avec un diabète. Les résultats décrivent trois niveaux différents (matériel, épistémique et moral) auxquels cet apprentissage se réalise. Ils montrent que son usage requiert un travail d'appropriation actif, l'intérêt d'un dispositif qui favorise les interactions entre participant-e-s et que les caractéristiques de l'outil tendent à reconfigurer la relation expert-profane.

Techno-social reconfigurations in diabetes (self-) care.

This article focuses on the ways in which a flash glucose monitoring system, FreeStyle Libre®, is introduced and used by people living with type 1 diabetes, their relatives and healthcare professionals. It draws on a multi-sited ethnography in a variety of clinical and daily situations, and on interviews with caregivers and people living with diabetes. We explore how the users develop knowledge-in-practice, and consider the use of self-management technologies to be largely dependent on locally grounded and situated care acts, and resulting from the relational, pragmatic and creative maneuvering of technology-in-practice. Our findings show that adjustments between users, their bodies and the technology are required, and show the reflexive work and practices of patients and relatives who learn to use the device in a proper way. Moreover, we reveal that practitioners see this technology as a tool that not only improves self-care practices but also clinical practices, and that wearing and using this new medical device may become a moral injunction for self-improvement. Our results illustrate the techno-social reconfigurations at work and the development of new ways of feeling, thinking and acting in diabetes (self-) care.

Socioeconomic Differences and the Potential Role of Tribes in Young People's Food and Drink Purchasing Outside School at Lunchtime.

Socioeconomic deprivation has been linked to food consumption practices, but studies investigating the food environment around schools provide mixed findings. Peer influence and marketing cues are considered important influencers of young people's behaviors. This study used a tribal theory lens to investigate the factors affecting pupils' purchasing and consumption of food/drinks outside schools at lunchtime. A survey was conducted with 243 pupils from seven UK secondary schools of differing socioeconomic status (SES). A purchasing recall questionnaire (PRQ) was developed and administered online at the participating schools to capture food and drink purchasing, intake, and expenditure. No significant differences were found in terms of energy and nutrients consumed or food/drink expenditure between pupils from schools of lower and higher SES. Enjoyment of food shopping with friends was linked with higher food energy intake and spend. Higher susceptibility to peer influence was associated with greater influence from food advertising and endorsements. Without ignoring the impact that SES can have on young people's food choices, we suggest that tribal theory can be additionally used to understand pupils' eating behaviors and we present implications for social marketers and policy makers.

Socio-Economic Factors, the Food Environment and Lunchtime Food Purchasing by Young People at Secondary School.

The aim of this paper is to report on the lunchtime food purchasing practices of secondary school students and some of the factors related to this purchasing, including the influence of socio-economic status (SES) and the food environment within and around schools. A mixed-methods study incorporating an online purchasing recall questionnaire and multiple qualitative methods was undertaken at seven UK secondary schools. The analysis shows that SES was intricately woven with lunchtime food practices. Three-quarters of participants regularly purchased food outside of school; those at low SES schools were more likely to report regularly leaving school to buy food. Young people's perception of food sold in schools in areas of low SES was often negative and they left school to find "better" food and value for money. Taste, ingredients and advertisements were factors that mattered to young people at schools with low or mixed SES; health as a driver was only mentioned by pupils at a high SES school. For public health initiatives to be effective, it is critical to consider food purchasing practices as complex socio-economically driven phenomena and this study offers important insights along with suggestions for designing interventions that consider SES. Availability of food outlets may be less important than meeting young people's desires for tasty food and positive relationships with peers, caterers and retailers, all shaped by SES. Innovative ways to engage young people, taking account of SES, are required.
