Background of the Study
Urbanization in Lagos State has accelerated dramatically over the past few decades, transforming lifestyles and dietary patterns. Rapid urban growth, characterized by high population density, sedentary occupations, and easy access to processed foods, has contributed to a significant rise in obesity rates among residents (Adeyemi, 2023; Balogun, 2024). Urban environments often limit opportunities for physical activity due to congested infrastructure, unsafe neighborhoods, and inadequate recreational facilities. Moreover, the proliferation of fast-food outlets and convenience stores in urban centers has altered traditional eating habits, leading to increased caloric intake and poor nutritional choices. As a result, obesity is emerging as a major public health challenge in Lagos State, with implications for non-communicable diseases such as cardiovascular disorders and type 2 diabetes (Ogunleye, 2023).
Urbanization also influences psychosocial stressors, which can contribute to weight gain through stress-induced eating behaviors and hormonal imbalances. The interplay between these factors creates an environment where obesity can thrive. Recent studies have shown a strong correlation between urban living and higher body mass index (BMI) levels among Lagos residents, highlighting the urgent need to address environmental and lifestyle factors that contribute to obesity (Ibrahim, 2024). Understanding how urbanization drives these trends is essential for developing targeted public health interventions that promote healthy lifestyles, improve urban planning, and ultimately reduce obesity prevalence in Lagos State.
Statement of the Problem
Despite economic development and modern amenities, Lagos State faces a growing obesity epidemic. The rapid urbanization has brought with it lifestyle changes that favor sedentary behavior and unhealthy eating, leading to increasing obesity rates. However, there remains a lack of comprehensive data linking urban environmental factors directly to obesity outcomes in Lagos. Existing public health interventions have not sufficiently addressed the urban-specific drivers of obesity, such as limited green spaces, poor urban planning, and the aggressive marketing of unhealthy food options (Chinwe, 2023). Furthermore, many residents lack awareness about the health risks associated with obesity, and there is inadequate access to preventive health services in densely populated urban areas. This disconnect has resulted in rising rates of obesity-related conditions, which strain the healthcare system and diminish the overall quality of life. Addressing these issues requires a multifaceted approach that incorporates urban policy, community education, and improved healthcare accessibility (Okeke, 2024).
Objectives of the Study
1. To determine the relationship between urbanization factors and obesity rates in Lagos State.
2. To identify the key urban environmental and lifestyle determinants contributing to obesity.
3. To recommend policy interventions aimed at reducing obesity in urban areas of Lagos.
Research Questions
1. How does urbanization influence obesity rates in Lagos State?
2. What are the primary lifestyle and environmental factors contributing to obesity in urban areas?
3. What policy measures can effectively mitigate obesity in Lagos?
Research Hypotheses
1. Urbanization is significantly associated with higher obesity rates in Lagos State.
2. Limited access to recreational facilities and healthy food options correlates with increased obesity.
3. Implementation of targeted urban health policies will reduce obesity prevalence.
Scope and Limitations of the Study
This study focuses on urban communities within Lagos State. Data will be collected through surveys, public health records, and environmental assessments. Limitations include potential response biases and the difficulty in isolating urbanization effects from other socio-economic factors.
