Twitter Summary: Key takeaways from Novo Nordisk’s Cities Changing Diabetes Summit in Copenhagen
Our team had the fortune of traveling to Copenhagen, Denmark to attend the inspiring Novo Nordisk Cities Changing Diabetes Summit. The Summit highlighted findings from the first year of the Cities Changing Diabetes Program, which aims to study the main social and cultural drivers of type 2 diabetes in urban settings. Over half of the world’s population lives in cities, including two-thirds of people with diabetes (more than 250 million people). Five cities across the world were chosen for the program’s first year – Houston, Copenhagen, Shanghai, Tianjin, and Mexico City – with Johannesburg and Vancouver joining the program for its second year.
For the most part, all five cities followed the rule of halves: half of all people with diabetes are diagnosed, half of those who are diagnosed are treated, half of those who are treated achieve targets, and half of those who achieve targets avoid complications. There were some notable exceptions, such as the fact that 98% of people diagnosed with diabetes in Copenhagen receive some treatment (not 50%) and closer to 70% (rather than 50%) of diagnosed patients in Mexico are not at their glycemic targets. The overall prevalence of diabetes ranged from ~5% in Copenhagen to just under 18% in Shanghai.
In addition to presenting the initial research findings from the five participating cities, the Summit featured keynote talks and panel discussions including the main social and cultural contributors of “urban diabetes” (type 2 diabetes in cities) and how to use cities as a model for large-scale social change.
Our top five takeaways
1) What are the biggest social risk factors for urban diabetes?
Dr. David Napier (University College London, UK) synthesized the findings from the past year, pointing to four social factors as key determinants of risk in a wide variety of populations:
Financial constraints: He emphasized that financial constraints include not only absolute poverty that prevents people from accessing basic resources, but also perceived constraints that limit people’s capacity to be proactive and hopeful about their future.
Resource constraints: While often linked to financial constraints, resource constraints are more specifically defined as lack of access to local healthcare, medications, nutritious food, exercise, or educational resources.
Geographical constraints: These encompass a range of problems magnified in urban environments, such as pollution, crime, infrastructure, and even isolation.
Time constraints: Dr. Napier’s main point was that people have to prioritize everything in their life. For people of all social classes, healthcare is often nowhere near the top of the list given many people are already overwhelmed by work and family responsibilities.
Dr. Napier stressed that cultural as well as social factors must be considered when addressing diabetes vulnerability. This means asking questions like (i) Do patients feel like they have agency to make changes? (ii) Do dietary recommendations conflict with people’s food traditions? (iii) Is diabetes the person’s biggest problem? and (iv) What does the person perceive as a normal or healthy body type?
2) Climate change and diabetes? A new partnership emerges.
Novo Nordisk Executive Vice President Mr. Jajob Riis announced that Novo Nordisk would be forging an alliance with the C40 Cities Climate Leadership Group. C40 was founded ten years ago in response to the lack of attention to climate change at the G20 summit of world leaders. Since then, it has grown to include 82 “mega-cities” that account for 25% of the world’s GDP and have collectively taken 8,068 concrete actions to reduce emissions as of 2014. C40 Executive Director Mr. Mark Watts noted that the member cities have reported that 30% of their actions resulted directly from sharing knowledge and best practices with other cities in the network, showing that meetings like this Summit can lead to real change.
3) How does peer support impact diabetes outcomes?
Dr. Edwin Fisher (Peers for Progress, Chapel Hill, NC) discussed how peer support can help address the social determinants of diabetes risk. He emphasized that most people with diabetes spend approximately six hours a year in a doctor’s office (at most!) and 8,760 hours a year managing diabetes on their own. As Dr. Fisher succinctly put it – “people need help living those 8,760 hours.” Peer supporters can be particularly well equipped to provide this help, providing assistance in areas such as daily management of diabetes, links to clinical care and community resources, and perhaps most importantly, social and emotional support. Indeed, Dr. Fisher cited studies showing that social isolation is as lethal as cigarette smoking.
Additionally, peer support is able to engage those high-priority groups whom healthcare too often “hardly reaches” – groups with especially high risk or poor clinical status, ethnic minorities, and fewer financial resources.
4) How can we make health easy and enjoyable?
During a very enlightening panel discussion, speakers brought up the importance of making public health interventions convenient and fun for people. As Ms. Helle Søholt (CEO, Gehl Architects) noted, 56% of people in Copenhagen bike to work because the environment compels them to – “it’s the obvious choice because it’s the fastest and easiest way to get around.” US Surgeon General Dr. Vivek Murthy recently spoke on the related topic of “happiness” as a public health focus at the TEDMED 2015 event – citing that happiness can only improve emotional wellness, but physical health as well.
5) Moving towards collective impact.
Cities Changing Diabetes highlights the complex scope of the challenges behind diabetes today. Beyond the biological components of diabetes, there are endless factors that contribute to diabetes risk – and that make it increasingly difficult to manage diabetes once it’s occurred. One critical theme from the Summit was the notion of “collective impact” – solutions that focus on cross-sector collaboration (i.e., food industry working with city planners working with hospitals, etc.) to address complex problems like diabetes prevention. As Mr. John Kania (FSG, Boston) put it, “If you want to change the system, you have to get the system in the room.”
