Obesity and Urban Environments.

Area of Science:

• Epidemiology
• Public Health
• Environmental Science

Background:

• Obesity is a significant global public health concern with severe health implications.
• Individual behaviors are risk factors, but the urban environment's role is increasingly recognized.
• Existing evidence on environmental influences is limited by country and completeness.

Discussion:

• Urban layout, sprawl, and access to healthy food and exercise are key environmental factors.
• The neighborhood social environment also plays a role in obesity and overweight.
• This review synthesizes current literature and highlights contributions within a special issue.

Key Insights:

• Urban physical and social environments are critical determinants of obesity.
• Factors like urban sprawl, food deserts, and lack of recreational spaces contribute to weight gain.
• Community-level interventions addressing environmental factors are needed.

Outlook:

• Further research is needed across diverse countries to fully understand environmental impacts.
• Policy interventions targeting urban planning and food access are crucial.
• Integrated approaches considering both individual and environmental factors are essential for combating obesity.
