Background

Urbanization is a defining demographic trend of the 21st century. While urban growth contributes to economic development and improved access to services, it also presents substantial public health challenges, including environmental pollution, infectious disease transmission, non-communicable diseases, mental health disorders, inadequate housing, and healthcare inequities.

Objective

To examine the relationship between urbanization and public health challenges and identify key determinants influencing health outcomes in rapidly growing urban populations.

Methods

A cross-sectional analytical study was conducted using data collected from 1,500 urban residents across metropolitan and peri-urban regions. Structured questionnaires, environmental assessments, and healthcare utilization records were analyzed. Descriptive statistics, chi-square tests, and multivariable logistic regression were employed.

Results

Approximately 68.4% of participants reported exposure to environmental pollution, while 41.7% experienced inadequate sanitation services. Non-communicable diseases were identified in 36.2% of respondents, and 28.4% reported significant mental health concerns. Rapid urban growth, overcrowding, low socioeconomic status, and limited healthcare accessibility were significantly associated with adverse health outcomes.

Conclusion

Urbanization has created complex public health challenges requiring integrated policy approaches. Sustainable urban planning, environmental protection, improved healthcare infrastructure, and health equity interventions are critical for promoting healthier cities.
