On March 4, 2026, the Swedish Public Health Agency (Folkhälsomyndigheten) marked World Obesity Day with a call for fundamental changes to living environments to address the growing obesity epidemic. According to the agency, more than half of Sweden's adult population had overweight or obesity in 2025, with the increase being continuous since 1980.
Anna Jansson, head of the unit for health-promoting lifestyles and upbringing conditions at Folkhälsomyndigheten, stated that societal changes are needed to reverse the trend. "To slow down the development, many actors in society need to contribute. It requires structures, support and environments that make it possible for everyone to live healthily," Jansson said.

The agency emphasized that environmental factors such as digitalization, product development, and product placement have affected people's eating habits and physical activity. These changes have also shaped new societal norms. The agency's work on overweight and obesity focuses on shifting from individual responsibility to society's opportunities for change.
World Obesity Day, observed annually on March 4 according to the World Obesity Federation, carries the theme "8 Billion Reasons to Act on Obesity" for 2026. The Swedish agency highlighted that obesity prevention has become particularly important in light of the recently decided cancer strategy "Increased Survival and Better Quality of Life," where overweight and obesity are identified as significant risk factors.
