Diabetes is surging worldwide, and urban living is a major factor. Here’s what you need to know:
- Global Impact: Over 589 million adults had diabetes in 2021, and this could rise to 853 million by 2050.
- Urban Risks: City life often means less physical activity, unhealthy diets, and chronic stress - all of which increase diabetes risk.
- Costs: In the U.S., diabetes-related expenses hit $412.9 billion in 2022.
- Solutions: Walkable cities, better food access, and community health programs can help reduce risks.
Urbanization changes how we live, eat, and move. While cities offer conveniences, they also create environments that make healthy choices harder. This article explores the links between urban living and diabetes and offers actionable strategies to build healthier communities.

How Urbanization Changes Daily Life
Urban life transforms how people move, eat, and handle stress. With 55% of the world's population now living in urban areas - a number expected to hit 68% by 2050 - these changes are reshaping lifestyles and increasing diabetes risks.
Less Physical Activity in Cities
City living often means less physical activity. Moving to urban areas typically involves a shift from physically demanding jobs in agriculture or manual labor to more sedentary office work. Add to that the growing reliance on cars, and walking or cycling becomes far less common.
The numbers paint a clear picture. A study in China showed that urbanization led to a 57% drop in physical activity for men and a 40% drop for women over nine years. Globally, only 1 in 4 adults meets the World Health Organization’s recommended activity levels.
Urban design also plays a role. Features like sprawling neighborhoods, single-use zoning, and poorly connected streets make walking inconvenient and encourage car use instead.
A 2023 study by Kwadwo Boakye and Marit Bovbjerg examined data from 138,206 adults in 698 communities across 22 countries. It found that higher population density resulted in 12.4% less physical activity, while areas with more paved surfaces saw a 29.2% drop in activity levels.
On top of that, modern conveniences like elevators, escalators, and delivery services reduce the need for even basic physical effort, such as climbing stairs or carrying groceries. This decline in movement often goes hand in hand with dietary changes that further raise diabetes risks.
Food Choices in Urban Settings
Cities reshape eating habits, often in ways that harm metabolic health. While urban areas offer a wider variety of food, many of these choices lean toward unhealthy options.
Processed foods dominate urban diets. People consume more refined carbs, added sugars, edible oils, and animal-based products, while eating fewer legumes, vegetables, and fruits. The "Western diet", characterized by high fat, sugar, and refined carbs, has become more common in cities worldwide.
In wealthier nations, ultra-processed foods account for 42% to 58% of daily calorie intake. Even in countries like Colombia and Mexico, they make up 16% to 30% of total energy consumption.
Cooking habits have also shifted. Frying has replaced traditional methods like steaming or boiling, increasing calorie content and altering nutritional value. Meanwhile, sugar-sweetened beverages and fruit juices are consumed more frequently, further boosting sugar intake.
The health impact is undeniable. A Canadian study found that people who ate the most ultra-processed foods had 31% higher odds of obesity, 37% higher odds of diabetes, and 60% higher odds of hypertension. Similarly, research in the UK revealed 11% higher odds of type 2 diabetes in areas with the highest concentration of ready-to-eat food outlets within a 1-kilometer radius.
Urbanites also rely more on pre-prepared meals or food cooked by others, which limits control over ingredients, portion sizes, and cooking methods - all crucial for managing blood sugar.
But diet isn’t the only factor. City life introduces chronic stress, which further complicates metabolic health.
Urban Stress and Health Effects
Living in cities brings constant stressors that directly affect insulin function and diabetes risk. These stressors - both environmental and psychological - trigger biological responses that disrupt blood sugar regulation.
Urban residents often deal with noise pollution, air pollution, traffic, crime, and violence. These factors not only lower quality of life but also activate stress hormones that interfere with insulin's ability to regulate blood sugar.
As Diabetes UK explains:
"Stress doesn't cause diabetes but it can affect your blood sugar levels and how you look after your condition."
Air pollution, particularly fine particulate matter (PM 2.5), is a serious concern. It triggers inflammation and disrupts hunger and fullness signals, contributing to what some researchers call "diabesity".
Noise pollution adds another layer of stress. Constant exposure to traffic noise or construction sounds has been linked to a higher risk of weight gain - a major factor in diabetes development.
Stress also disrupts hormones, increasing appetite and calorie consumption. Research shows that people with more severe depression symptoms and frequent exposure to urban stressors are more likely to develop insulin resistance. Over time, chronic stress keeps blood sugar levels elevated, increasing the risk of diabetes complications.
The fast-paced, densely populated nature of city life often leaves little room for recovering from these stressors, making it even harder to maintain metabolic health.
How Cities Drive Diabetes Rates
The connection between urbanization and diabetes is anything but simple. While cities provide better access to healthcare and a wide variety of food choices, they also create challenges that can worsen diabetes outcomes, especially for vulnerable groups. Factors like income, geography, and healthcare availability all play a role in shaping this relationship.
Income and Healthcare Access Challenges
The numbers paint a stark picture: diabetes rates climb as income drops. Middle-income Americans experience a 40% higher prevalence of diabetes compared to high-income individuals. For those near the poverty line, the rate jumps to 74.1%, and for individuals living in poverty, it doubles to 100.4% higher. Education levels and neighborhood conditions also matter - adults with less than a high school education face the highest diabetes incidence at 10.4 per 1,000 people and are twice as likely to die from the disease. Living in disadvantaged neighborhoods compounds the problem, with poor adults in these areas twice as likely to have diabetes compared to their nonpoor counterparts. In fact, type 2 diabetes is more common in neighborhoods with lower incomes, fewer high school graduates, more single-parent households, and overcrowded housing conditions.
Access to care is another major hurdle. High medical costs, limited healthcare facilities, and unstable housing make it difficult for many to receive preventive care or manage chronic conditions effectively.
However, targeted community programs show promise. For instance, in three Indianapolis neighborhoods where diabetes prevalence was 23.3% - much higher than the national average of 14.7% - Community Health Worker (CHW) programs yielded positive outcomes. These neighborhoods, which had higher poverty rates (35%–38% compared to 19% nationally) and a larger proportion of people of color (72%–94% versus 44% nationally), saw participants achieve an average reduction of 0.54 in A1C levels over time.
While urban areas face significant disparities, rural communities present a different but equally concerning diabetes narrative.
City vs. Rural Diabetes Rates
Interestingly, despite the hurdles faced in cities, rural areas report even higher diabetes rates. In 2021, the prevalence of diabetes in rural areas was 14.3%, compared to 11.2% in urban areas. Some states showed rural diabetes rates as high as 21.3%, while urban rates ranged from 6.9% to 15.5%.
The gap in diabetes mortality between urban and rural areas has also widened significantly, tripling between 1999 and 2019. Several factors contribute to this disparity. Rural populations tend to be older, have lower household incomes, and face higher obesity rates - 35% compared to 29.6% in urban areas. Additionally, educational attainment is generally lower in rural communities, further exacerbating health challenges.
Healthcare access is another critical issue. Over 63% of primary care Health Professional Shortage Areas are located in rural regions. In 2019, 15.4% of rural residents lived below the federal poverty line, compared to 11.9% of urban residents. Limited economic mobility in these areas also increases exposure to food insecurity and other diabetes risk factors.
Even after accounting for factors like education, income, and obesity, rural–urban diabetes disparities remain striking in states like Florida, Illinois, Kentucky, Maryland, North Carolina, Oregon, and Virginia. Notably, North Carolina and Oregon continue to show significantly higher diabetes rates in rural areas despite these adjustments.

Ways to Lower Diabetes Risk in Cities
Urban living often presents challenges that can increase the risk of diabetes, but cities also hold incredible potential to support healthier lifestyles. Through smart urban planning, better food access, and targeted health initiatives, cities can become environments that actively promote well-being.
Building Walkable Cities and Parks
Creating walkable neighborhoods is one way to directly address diabetes prevention. Studies show that adults living in highly walkable areas have a lower prevalence of obesity (43%) compared to those in less walkable areas (53%). Additionally, people in less walkable neighborhoods face a 20% higher risk of pre-diabetes after eight years and are 30% to 50% more likely to develop diabetes. Moving to a highly walkable area has even been linked to a 54% lower chance of being diagnosed with high blood pressure.
"The built environment can influence physical activity levels by promoting active forms of transportation, such as walking and cycling over passive ones, such as car use", explains Dr. Gillian L. Booth, M.D., M.Sc., from the University of Toronto.
Public transportation also plays a role in encouraging physical activity. Around 29% of public transit users clock more than 30 minutes of daily physical activity just by walking to and from transit stops.
Cities can adopt practical strategies to boost walkability, such as adding bike lanes, safe crossings, well-maintained sidewalks, and adequate lighting. Urban planning that mixes residential, commercial, and recreational spaces can also make it easier for people to walk or bike to work, school, or shops.
"We need policies that promote healthier eating habits and opportunities to engage in active forms of transportation. Designing neighborhoods that have safe and effective public transit options, cycling infrastructure, and walking paths may reduce traffic-related pollution", Dr. Booth emphasizes.
Making Healthy Food Available
Access to healthy food is another critical factor in reducing diabetes risks in urban settings. Currently, 40 million Americans struggle to find fresh, affordable food in their neighborhoods. Low-income areas have 25% fewer supermarkets and more convenience stores compared to middle-income neighborhoods, making it harder for residents to maintain a balanced diet.
The presence of supermarkets can make a big difference. Adults living in areas with supermarkets have lower obesity rates (21%) compared to those in areas without them (32% to 40%). Supermarkets also encourage healthier eating habits, as residents are more likely to meet fruit and vegetable consumption guidelines when they have access to one.
Programs like DC Central Kitchen's Healthy Corners initiative prove that change is possible. By working with 54 corner stores to offer affordable produce at wholesale prices, they’ve sparked a 162% increase in produce sales. Their SNAP Match program, which provides $5 coupons for fresh produce, has further boosted sales by 70% for local produce and 16% overall.
"Healthy Corners is the ultimate myth-busting food access program. There is proof that small businesses want to be part of a healthier, more sustainable community and that low-income consumers are interested and want to put healthy food on the table for themselves and their families", says Alexander Moore, Chief Development Officer at DCCK.
Policymakers can support similar initiatives by forming Food Policy Councils, increasing SNAP enrollment, encouraging farmers' markets, and incentivizing supermarkets to open in underserved areas.
Local Health Programs
Community-based health programs are essential for addressing diabetes risks, especially in urban areas where racial and ethnic minorities face disproportionately high rates of diabetes-related health issues. For example, 12.6% of African-American adults have diabetes compared to 7.1% of non-Hispanic white adults, and diabetes-related complications are 50% to 100% higher in minority populations.
Some successful programs include Detroit’s Community Health and Social Services (CHASS), which used a multi-disciplinary team to address uncontrolled diabetes in 35% of its patients. In Richmond, The Daily Planet integrated primary care, pharmacy, behavioral health, and nutrition services to help high-risk, homeless patients. Meanwhile, the Institute for Family Health in Harlem provided bilingual diabetes education alongside primary and behavioral health care for 1,000 patients. Washington, D.C.’s Mary’s Center introduced a nurse-led program combining case management, group education, and social engagement to improve patient self-management.
Community Health Workers (CHWs) have proven especially effective in urban settings. By providing education and support in familiar, community-centered environments, CHWs help bridge gaps in care.
"A strong network of community health centers is critical to improve access to our health system, and this year's winners represent what's possible for community health in the U.S. The wellness, prevention, and care community health centers provide help avoid unnecessary hospital visits and sometimes represent the only care for some of our country's most vulnerable populations", notes Vincent A. Forlenza, Chairman, CEO, and President of BD.
Tailored education programs, CHWs, and quality improvement strategies can significantly reduce diabetes disparities when thoughtfully designed to meet the needs of specific populations, including those with disabilities and racial or ethnic minorities. By focusing on these targeted approaches, cities can make meaningful strides in improving public health.
Conclusion
The link between urbanization and diabetes paints a complicated picture, filled with challenges that require urgent action. With over 55% of the global population now living in cities - and this figure expected to climb to 68% by 2050 - the health risks tied to urban lifestyles are becoming increasingly pressing. Factors like less physical activity, unhealthy eating habits, and chronic stress create a perfect storm for rising diabetes rates, emphasizing the need for focused solutions.
Urban areas consistently show higher diabetes risks, as global data confirms. But these challenges also present an opportunity for creative and impactful interventions.
The financial toll of diabetes is staggering. On average, individuals with diabetes face annual medical costs of about $19,700 - more than twice the expenses of those without the condition. Without decisive action, the prevalence of diabetes is expected to rise by 54% by 2030, compounding both personal and economic hardships.
Still, cities hold immense potential for change. Urban environments can serve as testing grounds for large-scale health initiatives. For example, efforts to create walkable neighborhoods and launch community health programs have already shown success in reducing diabetes risks. By expanding on these strategies - such as improving access to fresh foods and addressing social determinants of health - cities can shift from being part of the problem to becoming part of the solution. Collaboration among urban planners, healthcare professionals, policymakers, and community leaders is key to fostering environments where healthy choices are the easy choices.
Advancements in research and the availability of health information are essential in this fight. As urban health issues grow more complex, platforms like MetforminDaily play a crucial role in making science-backed guidance on diabetes management and lifestyle changes accessible. Emerging technologies, such as AI models and digital twins, also bring exciting possibilities for personalized diabetes care in urban settings. When combined with proven public health strategies, these tools can help transform cities into hubs of prevention and wellness.
The connection between urbanization and diabetes goes beyond medical concerns - it reflects deeper issues in how cities are designed and lived in. By addressing these challenges with evidence-based solutions, we have the chance to significantly improve the health and well-being of billions of people living in urban areas. The time to act is now.
FAQs
How does urbanization lead to higher diabetes rates?
Urbanization has a major impact on rising diabetes rates, largely due to shifts in lifestyle and surroundings. City life often means less physical activity, higher consumption of processed, calorie-dense foods, and greater exposure to stressful environments. Together, these factors significantly increase the likelihood of developing type 2 diabetes.
Studies reveal that people living in urban areas are 2 to 4 times more likely to develop diabetes compared to their rural counterparts. The rapid expansion of cities also tends to bring higher rates of obesity and other metabolic issues, both of which are strongly tied to diabetes. Tackling these problems calls for encouraging healthier eating habits, improving access to exercise options, and addressing urban stressors to foster better overall health.
What steps can cities take to lower diabetes risks for urban residents?
Cities have the power to make a real difference in reducing diabetes risks for their residents by taking a few key steps. For starters, making parks and green spaces more accessible can encourage people to get moving and embrace healthier habits. Whether it’s jogging, walking, or simply spending time outdoors, these spaces promote an active lifestyle.
Improving walkability and ensuring neighborhoods are safe can also inspire more people to walk or bike as part of their daily routines. When streets and public areas are designed with pedestrians and cyclists in mind, regular exercise becomes a natural part of life.
Another game-changer? Investing in public transportation and making sure residents have access to affordable, nutritious food. These efforts tackle issues like obesity and inactivity, both of which are major contributors to diabetes. By prioritizing these initiatives, cities can foster healthier environments and help their communities thrive.
Why are diabetes rates often higher in rural areas compared to cities?
Rural areas often grapple with higher diabetes rates compared to cities, and several factors contribute to this disparity. One major issue is limited access to healthcare. People in rural communities may have to travel long distances to see a doctor, making regular checkups and early diagnosis more challenging. On top of that, finding healthy food options can be tough, with fewer grocery stores offering fresh produce. Combine that with fewer opportunities for exercise - like gyms or safe walking paths - and managing or preventing diabetes becomes even harder.
Other contributing factors include higher obesity rates, lower income levels, and an aging population, all of which increase the risk of diabetes. While urban areas have their own health challenges, they tend to provide better access to healthcare and more resources to support a healthier lifestyle.
