The implications of defining obesity as a disease: a report from the Association for the Study of Obesity 2021 annual conference
Unlike various countries and organisations, including the World Health Organisation and the European Parliament, the United Kingdom does not formally recognise obesity as a disease. This report presents the discussion on the potential impact of defining obesity as a disease on the patient, the healthcare system, the economy, and the wider society. A group of speakers from a wide range of disciplines came together to debate the topic bringing their knowledge and expertise from backgrounds in medicine, psychology, economics, and politics as well as the experience of people living with obesity. The aim of their debate was not to decide whether obesity should be classified as a disease but rather to explore what the implications of doing so would be, what the gaps in the available data are, as well as to provide up-to-date information on the topic from experts in the field. There were four topics where speakers presented their viewpoints, each one including a question-and-answer section for debate. The first one focused on the impact that the recognition of obesity could have on people living with obesity regarding the change in their behaviour, either positive and empowering or more stigmatising. During the second one, the impact of defining obesity as a disease on the National Health Service and the wider economy was discussed. The primary outcome was the need for more robust data as the one available does not represent the actual cost of obesity. The third topic was related to the policy implications regarding treatment provision, focusing on the public's power to influence policy. Finally, the last issue discussed, included the implications of public health actions, highlighting the importance of the government's actions and private stakeholders. The speakers agreed that no matter where they stand on this debate, the goal is common: to provide a healthcare system that supports and protects the patients, strategies that protect the economy and broader society, and policies that reduce stigma and promote health equity. Many questions are left to be answered regarding how these goals can be achieved. However, this discussion has set a good foundation providing evidence that can be used by the public, clinicians, and policymakers to make that happen
Development and initial qualitative evaluation of a novel school-based nutrition intervention – COOKKIT (Cooking Kit for Kids)
Abstract Background Excess weight and an unhealthy diet are risk factors for many cancers, and in high income countries, both are more prevalent among low income families. Dietary interventions targeting primary-school aged children (under 11) can improve healthy eating behaviours, but most are not designed to support the translation of skills learnt in the classroom to the home setting. This paper assessed attitudes and approaches to cooking and eating at home, and the potential to enhance engagement in healthy eating through the COOKKIT intervention. Methods COOKKIT is an intervention to deliver weekly cooking classes and supportive materials for low-income families to maintain healthy eating at home. Preliminary qualitative interviews were conducted with teachers and parent–child dyads from a range of primary schools in the UK to explore attitudes, barriers and facilitators for healthy eating and inform the development of COOKKIT. Following implementation, ten children (8–9 y/o) participated in post-intervention focus groups, alongside interviews with teaching staff and parents. Results Thematic analysis identified five themes under which to discuss the children’s experience of food, cooking and the impact of COOKKIT: Involving children in planning and buying food for the family; Engaging children in preparing meals at home; Trying to eat healthy meals together in the midst of busy lives; Role-modelling; and Balancing practicalities, information and engagement when delivering cooking classes. Conclusions Results suggest COOKKIT provides engaging and easy to follow in-school resources for children and school staff with take-home kits facilitating continued engagement and reinforcing lessons learned in the home environment. Importantly, participants highlighted the combination of healthy eating information, applied practical skills and low costs could support families to continue following the COOKKIT advice beyond the intervention, suggesting further evaluation of COOKKIT is warranted

Analysis of the ARTIC V4 and V4.1 SARS-CoV-2 primers and their impact on the detection of Omicron BA.1 and BA.2 lineage-defining mutations
The ARTIC protocol uses a multiplexed PCR approach with two primer pools tiling the entire SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) genome. Primer pool updates are necessary for accurate amplicon sequencing of evolving SARS-CoV-2 variants with novel mutations. The suitability of the ARTIC V4 and updated V4.1 primer scheme was assessed using whole genome sequencing of Omicron from clinical samples using Oxford Nanopore Technology. Analysis of Omicron BA.1 genomes revealed that 93.22 % of clinical samples generated improved genome coverage at 50× read depth with V4.1 primers when compared to V4 primers. Additionally, the V4.1 primers improved coverage of BA.1 across amplicons 76 and 88, which resulted in the detection of the variant-defining mutations G22898A, A26530G and C26577G. The Omicron BA.2 sub-variant (VUI-22JAN-01) replaced BA.1 as the dominant variant by March 2022, and analysis of 168 clinical samples showed reduced coverage across amplicons 15 and 75. Upon further interrogation of primer binding sites, a mutation at C4321T [present in 163/168 (97 %) of samples] was identified as a possible cause of complete dropout of amplicon 15. Furthermore, two mutations were identified within the primer binding regions for amplicon 75: A22786C (present in 90 % of samples) and C22792T (present in 12.5 % of samples). Together, these mutations may result in reduced coverage of amplicon 75, and further primer updates would allow the identification of the two BA.2-defining mutations present in amplicon 75: A22688G and T22679C. This work highlights the need for ongoing surveillance of primer matches as circulating variants evolve and change.Publisher PDFPeer reviewe
